The WiFi router, the smart light, the TV, the phone, etc., all have WiFi chips inside. Ever imagine replacing those chips with an open-source design?
The openwifi project has been online for more than 2 years. We have paved solid steps towards an open-source WiFi chip. Now if you have commercial off the shelf FPGA boards, you can download our design onto your board and start to use this FPGA based WiFi in the same way as other commercial WiFi chips!

Itake care of my personal and professional notebooks. I also maintain apowerful build server at home and a remote VPS hosting my blog. From times totimes I even use a single board computer to host some services.
A few years ago, all those machines ran different, dedicated Linuxdistributions: Ubuntu, ArchLinux, Debian, Raspbian, making the maintenance anightmare. That was before diving into GNU Guix.
In this talk, I'll expose how GNU Guix, as an advanced package manager andLinux distribution can be advantageously used on any kind of machine fromsingle board computers to VPS machines.
The declarative aspect of GNU Guix allows to have various operating systemdefinitions inheriting from each other while the associate tooling such as"guix system" and "guix deploy" ease the deployment and upgrade tasks.

The reason for this popularity extends beyond the syntax of the language to the power of the Java Virtual Machine (JVM). With its ability to handle internet-scale workloads, the JVM delivers the performance required for mission-critical enterprise applications.
In this session, we’ll explore Java as it is in 2022. JDK 17 is the ninth (yes, ninth) release in four years. As a long-term support (LTS) release, this is one that many users will choose to use in production. We’ll review the significant new features developers will now be able to exploit as they develop their next applications. With JDK 18 just around the corner and longer term projects like Loom likely to be included soon, what does this year hold for Java?

And you don’t have to be a developer to search, aggregate and visualise your data. Whether you need an affordable business analytics tool or you want to analyse log data in near real time, OpenSearch can help you. And all of it through a visual interface of OpenSearch Dashboards.
After listening to this talk you’ll understand the basics of working with an OpenSearch cluster and different use cases it supports. You’ll also learn to create your first search and aggregation query and visualise the outcomes with the help of OpenSearch Dashboards.
This talk is for those who have little or no previous experience of OpenSearch (and Elasticsearch) and who are looking for solutions for searching, monitoring or data analysis with no coding required.

In this session, you will get a tour of key Kafka features using the delightful web UI of Jupyter notebooks.
Use the notebooks to see Kafka and Python in action, producing and consuming records. We’ll also cover how to get the best from your application by making good use of topic partitioning and consumer groups. From high-level concepts to nitty-gritty details, this session will equip you with the skills you need to build applications with Kafka. Recommended for anyone curious about Apache Kafka or using Jupyter to work with or learn new data platforms.

Trying to solve these type of problems by hand is a tedious task often resulting in sub-optimal decisions.
In this talk, we'll understand how PostgreSQL recursive queries can help. Starting from the proper problem definition, we'll then explore how to build queries that call themselves recursively, what are the risks associated with this approach and safeguards we can set to optimise performances. Finally we'll demonstrate how two new features released in PostgreSQL 14 enable an easier handling of the recursive statements.
If you're into PostgreSQL and eager to understand how recursion works, this session is for you!

After 10 years, it was necessary to review and update the strategy based on the evolution of the office suite market, to improve the sustainability model. Enterprises are not supporting the project as much as individual users. Over time, this can represent a threat for the sustainability of the project. We have changed our strategy to educate enterprises about the right approach to FOSS, by giving back to ensure the long term sustainability of the LibreOffice project.

Recently, this trend has penetrated the fields of crime and police research. The presentation highlights use cases of big data computation and HPC for typical datasets in crime science: crime records, emergency call data, and police GPS data. The focus lies on spatiotemporal applications (i.e., geocoding, map matching, spatial and temporal algorithms). The datasets come from a collaborative project with a Belgian police force and encompass approximately 200,000 crime records and 400 million individual GPS datapoints (x and y coordinates + timestamp). The project aims at establishing the crime preventive effect of police patrols through a longitudinal research design. Besides offering novel computational solutions for crime scientist, these kinds of datasets introduce important ethical considerations as well as potential biases in human-led data entry and collection. These considerations underline the need for social scientists to become more literate in the computational sciences and support the framework of ‘crime science’ as a discipline of exact methods and data sources.

That means: Where it is, Who can see it, Who can't see it.
Used as a global file system, Peergos provides a private space where you can store, share and view your media and documents. Individual content can be shared outside peergos via secret links and whole static sites can be hosted via a gateway.
Used as an application platform, Peergos provides productivity tools like a calendar, todo/project boards and document viewer/editors. In the near future users will be able to add their own applications using the same secure application protocol.
Used as a communication platform, Peergos provides a social media feed, group chat and an email bridge.
Peergos is open source and self-hostable.
This talk with introduce Peergos. It will expand on the project's goals, its architecture and some of the technical details. It will provide a walkthrough of the current functionality and a sneak-peak of what the future may hold.

The project consists of all necessary RTL components, e.g. PCIe DMA engine, NIC datapath, MAC, PHY and integration of vendor specific IP cores, such as transceivers and PCIe hard-IP cores. In combination with the provided driver and debugging utility the ready-to-experiment state just requires a supported FPGA card + compiler to kick-off playing with the project.
The existing state provides the platform for future In-Network Compute platform research, allowing for application logic to be balanced across hardware acceleration and software flexibility. The platform uniquely allows for experiments with lower layer protocols, e.g. PHY layer coding.
The talk concludes with an overview about short term and mid term goals of the project.

What if this self-sovereign, user owned and controlled, privately sharable trust network could become the backbone to unite our many disparate decentralized web apps and platforms? These are the goals of Trust Graph, and its reference implementation built on Holochain.
In this talk we will cover:
source, target, semantic content, normalized scalar valueFlame graph is way to visualize profiling data that allows the most frequent code paths to be identified quickly and accurately. They can be generated using Brendan Gregg's open source programs on github.com/brendangregg/FlameGraph, which create interactive SVG files to be checked in browser. The source of profiling data does not really matter - it can be perf profiler, bpftrace, Performance Schema, EXPLAIN output or any other source that allows to convert the data into the expected format of comma-separated "path" plus metric per line.

Commercial debates over licensing and revenue models around FOSS based businesses peak in 2021 with the Elastic transition away from FOSS to an SSPL licence and the fallout and debate from this.
The European Commission's Digital Decade is clear that its basis will be a FOSS infrastructure and Europe has been passing laws and regulations to support its open first approach, as it seeks digital and data sovereignty.
The inevitable success and adoption of FOSS in our national infrastructures and recent security issues have the minds of Governments focused on FOSSS, to the extent that the White House plans a meeting to discuss FOSS security in January having issued an ordinance recommending the use of Software Bill of Materials.
China's Ministry of Industry and Information Technology has shared a 5 year software plan saying "software defines the world of the future, open source determines the future of software," as it plans global collaboration to improve its open source activities.
In the UK, hosting COP26 shone a spotlight on energy and the UK Energy Sector Digitalisation Task force which has already suggested Open Data, will consider the use of open source software by default in its recommendations to Government in January. Whilst the NHS' data strategy issued in 2021 requires that open source software should be the default in healthcare.
This talk will stitch together these global threads, laws and policies to take a holistic view on the insurmountable success of FOSS in the last decade and the inevitable challenges being faced as a consequence of that success and the very nature and heart of FOSS in the Commons.
Sharing some policy suggestions and thoughts this talk will consider whether it may be time to shift the landscape. Is 2022 the year to recognise the need for FOSS to be characterised as a public good and to secure the interaction not only of business but of the State in funding and securing FOSS in the long term? How can this ensure sustainability of FOSS through its maintenance and sustainability of the planet by elevating the role of FOSS within environmental sustainability?
With a deep consideration of recent economic and policy discussions this keynote talk with pull many strands together to start 2022 with a focus on FOSS, funding and a secure and sustainable future.

Version 0.0.1 was released 20 years ago. The latest release was also the first release that included support for a few Director games.
MacroMedia Director, later Adobe Director, was a multimedia application authoring platform. Its ease of use led to a huge number of graphic adventure games being written with it. This was the late 90's. Some well known games are the Journeyman Project, Total Distortion and Spaceship Warlock.
One challenge to over come was to work on the code without breaking other parts.We'll go over the architecture of ScummVM, dive deeper into the Director Engine and land on how tests improved the code.

In some circumstances, developers have to reboot their systems in order to patch security vulnerabilities, fix bugs, and add new features, which will bring unavoidable downtime for running applications. Live-patch is an elegant solution. But, it can only work in 30 percent of circumstances. In our project, we put another solution into practice. We use a checkpoint-and-restart mechanism to retore applications' status and then switch the kernel fastly.

It does so by taking a compositional approach that reduces the complexity of managing configuration from a combinatorial problem to a linear problem. CUE is based on 20 years of experience in the field of configuration. Its declarative, aspect-oriented approach is powerful yet simple, making it possible to manage large amounts of configuration data and policies in multiple formats (JSON, YAML, Protocol Buffers, OpenAPI, etc.) with relative ease.It also makes CUE well suited to a wide range of applications.
This all sounds great! But for someone new to CUE, it may not be obvious how to get started.
In this talk, Marcel van Lohuizen and Paul Jolly start with a quick overview of CUE the language, then move on to present practical examples of CUE in action, including common patterns for validation, policy, integration with existing non-CUE configuration and more. Because CUE is new, established patterns are still in the making, but at the very least it will be a reflection of the current thinking.
No previous experience of CUE required, although familiarity with an existing configuration and data languages will help provide some context to the examples.

Although it wasn't a complete implementation, it was impressive enough to be remembered now, almost 40 years later. But running it in 2022 requires at least an emulator, ROM file, and the .P file, which limits the appeal to retro enthusiasts and excludes the intended audience - chess players!
So, I modified the EMF emulator (and the game) to run as an emulator-as-a-service, so that it can be played via the lichess servers with a modern web-friendly interface.

However, attackers will still use various methods to attack SGX and user’s Enclaves. And user’s code inside Enclave may also have bugs, which can be leveraged by the attackers. We are from intel SGX SDK team, we have conducted security analysis and pen-test for SGX Enclave (based on SGX SDK) during the past 10+ years. We want to summarize some past exploits we encountered in our daily work and what's the mitigation, hope it can help the Enclave developers to write more secure Enclave code.

Humanities data are interesting (both technically and to the public). They are rich in text, images, objects, people and events, heterogeneous, eminently linkable and sparse-matrix. Personal computers, the internet and other accessible technologies have spawned an exploding field (or fad?) known as Digital Humanities (DH), and opened exciting new horizons for research and public engagement.
However, this technological turn has created many problems for a poorly funded research culture with 1-3 year grant funding cycles - choice of appropriate technology, finding and retaining technical staff, initial and ongoing costs, sustainability ... The outcome is often least-effort and inadequate technology (eg. spreadsheets) or ad hoc development, incomplete functionality, maintenance nightmares, data silos and rapid end-of-funding decay; only rich or statutory organisations can maintain a multi-component system for long. Heurist aims to overcome these problems by mutualised Open Source development, schemas stored as editable data rather than fixed structures, demand-driven priority development, and free centralised services and maintenance.
In this presentation I will outline the evolution of our development process, from haphazard experimentation and many costly unused features (2005 - 2009) to a coherent, stable but evolving structure and Extreme Programming (aka living dangerously!), driven by immediate user requirements and incremental daily interface refinement. I will outline some of the fundamental principles we use to maintain backwards compatibility, stability, rapid development and low cost of maintenance for such a complex beast and for so many projects, on a self-funding staff of just 3 FTE. I also hope to attract some technical collaborators, as most of our users are (by design) non-technical.

MariaDB Server 10.7 is the first release following this model.
Some of these releases will have 1 year support cycles, while others will be supported long term just like before. In this talk, I will present the pros and cons of this new release model, what it means for the MariaDB Server community, its users and also its developers. This will also give the community a chance to better understand the changes and give us feedback and ultimately ensure MariaDB Server properly serves its purpose of being a true Open Source Database.

This provides a concise, clean and extensible tool for parsing text and triggering Actions according to the content. Navigation aids such as buoys and markers sport flashing lights with characteristics such as color, duration, phase, occulting, speed, height, visibility and so on are represented on navigation charts by way of a short code e.g. Fl(4)15s37m28M.
This talk aims to show how raku provides the average coder (me) with a new practical alternative to Regexs and/or specialist recursive descent modules. It should illustrate how the combination of the raku built-in OO system and Grammars/Actions keeps the problem domain / problem solution in focus via code and visual examples.

Ada is a feature-rich language, but what really makes Ada stand-out is that the features are nicely integrated towards serving the goals of software engineering. If you prefer to spend your time on designing elegant solutions rather than on low-level debugging, if you think that software should not fail, if you like to build programs from readily available components that you can trust, you should really consider Ada

OSPOs often oversee aspects of a company’s open source license compliance process and supply chain as one of the first activities. The responsibilities include:
To a certain degree, any organization calling itself an OSPO likely indicates the organization has reached a maturity stage where Executive-level recognition that OSS is an important strategic asset and builds a critical mass of processes, procedures, and tools to streamline and facilitate open source consumption and participation across divisions. Indeed, these activities also include a wide range of software composition analysis solutions such as Software Bill of Materials (SBOM), license management scanning, or continuous monitoring tools.
While some OSPOs rely on Software composition analysis vendors like Synopsys and Tidelift, others decide to make their own built-in solutions. During this presentation, Ana Jimenez, PM at TODO group (an open community of organizations who run OSPOs worldwide), will introduce the evolution and expansion of OSPOs over the years from a supply chain perspective, some of the common SCA tooling used, as well as how OSPOs can contribute and nurture the ecosystem of SCA tools to adapt to the needs of the different industries.

Today electronics can use data rates of several gigabits per second. At such speed wires and tracks are far from being perfect, bugs and glitches may arise because of them. Even low-speed designs are not safe and can encounter high-speed problems because they use high-speed capable chips.
While the electronic CAD software KiCad has the tools to design high-speed boards, there is no tool to validate them. The usual way is to apply all good practice rules, even if they are sometimes overly conservative and might waste some board space. The layout plays an important part in both PCB performance and cost. A PCB simulator, integrated into KiCad, would help designers to find their balance between the two. This presentation is a short introduction to IBIS and FEM, tools that will most certainly be needed for such high-speed simulations, and provides application examples.

To elevate from a collection of patterns to a system, you need to provide clear standards and reasoning. Clear and comprehensive documentation helps you put this system together into something everyone can use.
This talk will go through how we open sourced the documentation for the Orbit design system and discuss what we learned from the process. It will discuss creating both visual and content standards for the docs and how it was all accomplished. The lessons from this experience can help in the creation of useful and accessible documentation to guide the design process.

Based on dictionaries and semi-automatic classification, it mainly allows its user to combine approaches of statistical computation, co-occurrence network and search for nested patterns. Inspired by pragmatic sociology, it focuses on the multiple forms of expression and argumentation used by actors, on language regimes and on the identification of transformations occurring in the research case. Initially distributed commercially, then from 2011, by the Doxa association, as shareware under a non-profit and ethical charter, it is now hosted by the Corpora association and developed under the aGPLV3 CECILL variant Affero compliant license.
In this presentation, we will discuss more specifically the question of the permanence of a research-targeted software approach, through its evolution over almost 30 years. During this period, evolving expectations and technical developments have led to a client/server step (which remained in the prototype stage) and now to the transition to SaaS. Based on this experience, we will also discuss the conditions we consider relevant for the durability of the software in a new interconnected phase. The broadening of its audience of users and developers calls for ever greater interoperability, on the technical level, but with an approach that combines non-profit and academic models (with limited resources) and business uses.

Garage is developped by Deuxfleurs, an experimental self-hosting collective.
Garage targets primarily home-grown clusters composed of second-hand commodity hardware, spread over multiple physical locations for redundancy. This deployment scenario implies strong constraints on the software, such as having to deal with slow nodes and high latency between nodes. In a fist part of this talk, we will show how Garage's design enables it to function very well in this scenario, contrarily to other solutions we have tested such as Minio or Glusterfs.
Garage is focused on implementing the Amazon S3 protocol, a de-facto standard that makes it directly usable as a storage backend for many web applications (such as Nextcloud) or as a backup target. A second part of this talk will be focused on showing how Garage integrates with Deuxfleurs' current self-hosting stack, and how it can be easily configured with a variety of applications.

Many tools, such as ImageJ, QuPath or CellProfiler are heavily used by researchers to quantitatively interpret those complex images. These tools perform tasks such as normalization, image segmentation, image masking or feature extraction. However, these tools are designed for usage on local workstations with a GUI and for the most part only allow vertical scaling to deal with an increase in dataset size. This limited scalability poses a problem as bioimaging datasets keep growing in volume.
Here, we introduce Scalable Cytometry Image Processing (SCIP). SCIP is an open-source tool that implements single-cell bioimage processing on top of Dask, a framework for distributed computing written in Python. By utilizing Dask to execute all computations, scalability is integral to the software allowing it to be executed on high performance computing clusters. Dask's smart task scheduling ensures computational resources are used efficiently. SCIP also takes advantage of Dask features such as fault tolerance, load balancing or data locality. This allows SCIP to process large datasets more efficiently and more robustly compared to other tools.

The Arcon philosophy is streaming first, similarly to systems such as Apache Flink and Timely Dataflow. However, unlike all existing systems, Arcon features great flexibility when it comes to its application state. Arcon's TSS query language allows extracting and operating on state snapshots consistently based on application-time constraints and interfacing with other systems for batch and warehouse analytics.

As talking to your database often forms a significant portion of the input and output of your application, it's important to do that asynchronously as well. With the release of version 1.4, SQLAlchemy added support for Asynchronous I/O for both its core and ORM features. This means that you can now use the popular SQL toolkit for Python in your asynchronous applications.
In my talk, I will introduce you to the newly added support for asyncio in SQLAlchemy. I will go over how easy it is to set up the new AsyncEngine, point you to some of the differences with synchronous SQLAlchemy, and show you some of the pitfalls to avoid. In addition, I will also show you how you can run your existing synchronous SQLAlchemy code asynchronously to help you transition to a fully asynchronous application. By the end of my talk, you should know enough to start your own asynchronous SQLAlchemy adventure.

Over the years, I have contributed to a variety of free and open source software projects, and since 2019, I have developed and maintained textnets, a Python package for text analysis that represents collections of texts as networks of documents and words, providing novel possibilities for the visualization and analysis of texts. In my field, such software development efforts are not usually rewarded, but I have been very fortunate. My academic superiors have been supportive of my endeavors, and a publication in the Journal of Open Source Software also helped me get official recognition for this work in the standard currency of my field.
While I developed textnets to scratch my own itch, I seek to make the package widely available by providing extensive documentation and making it easily installable across multiple platforms. This part of my software development work -- learning the intricacies of version control, package managers, continuous integration testing, and dependency management -- puts me in a position to learn not just about the technical side of coding, but about the social side of the choices developers make. At least in the Python world, the way you learn about what dependencies to use, if any, and how many, is informed by norms more than by technical considerations, and the same is true for much else. By engaging in software development work, I engage in a version of the research method of participant observation -- learning by taking part -- that sociologists have called observant participation -- becoming part of what you want to learn about. In my case, I want to learn not just about software development and its culture and norms, but the wider world of free software, hacker culture, artistic practice based on FOSS tools, and more.
In my talk, I provide some background to the development of textnets, give a brief demonstration of the package's features, and finally reflect on my experiences engaging in observant participation as well as some of the insights I have gained and still hope to gain.
This talk aims at presenting our trials and tribulations as well as our achievements in designing a compliance software project for open source licenses.
"Are all module licenses in our software project compliant with each other ?"Many of our customers have asked us this question even though they already had a plethora of software solutions (not always FOSS software) dealing with this topic.This surprised us, and led us to seek out the cause of their uncertainty. We then discovered that many solutions only look for potential risks and provide reports both too detailed, from the legal POV, for practical use by an engineer, and too technical for practical use by a lawyer.
As engineers are bound to do, we thought there might be a technical solution to this and launched a project.As engineers launching a project are bound to do, we encountered a few hitches and made some discoveries along the way.
Today, here we are to show off the problems we encountered and how we overpassed them, but also to mention that we are open to your contributions (on technical matter or just for suggestions).

It gets worse when hardware interaction is required. This leads to a comparatively poor culture of unit testing in kernel code, where both come together.
In this talk, I’m going to highlight one particular method of unit testing the page table manipulation code in Hedron, a microkernel written in C++ specially geared towards virtualization workloads. This code safely modifies page tables that are concurrently used by the CPU. Usually, unit tests only check whether the state after an operation meets the expectation of the programmer. In contrast, Hedron employs completely deterministic unit tests that show that the CPU will always see a valid virtual memory mappings while a page table manipulation is in progress (for the tested cases).
The goal of this task is to show that unit tests can be a powerful tool even for properties of code that are usually not deemed unit testable.

Or at least, this was the thesis for my 2021 FOSDEM talk "Imagining the Ideal Language for Writing Free Software".
Over the past year, however, I've concluded that this argument – while correct any many areas – does not apply to dependency management. When it comes to dependency management, writing Free Software isn't on the opposite end of the spectrum from writing code for Google — it's on the same end, but even further along. This talk will elaborate on what I mean by that statement and discuss the implication I believe that this has for Raku.

However, in the case of CryptPad, implementing such functionality presents a number of challenges to preserve our privacy requirements. This has long held back adoption of our platform as it prevented users from migrating existing documents and/or integrating CryptPad in their workflows.
In this talk I will summarize our work on INTEROFFICE, a project realized by the CryptPad team in 2021 with funding from the EU's Next Generation Internet (NGI) DAPSI program. The core of this work consists of a new set of converters that use Web Assembly to perform conversions between file formats in the browser. This allows for CryptPad to be vastly more inter-operable while preserving end-to-end encryption (the server still has no access to the content being converted).
Speaking as the designer on the team, I will focus on the research we conducted with users and on the ways this new functionality is making its way into CryptPad's interface.

Instead of focusing on inclusion, innovation, and collaboration a new generation of so called open source drive companies has emerged flush with investor money and looking to maximize the returns for their investors and shareholders at all costs. In an effort to accelerate “revenue” and “profits” these companies are looking to rewrite the definition of what they consider open source. We are in a battle for not only the hearts and minds of the FOSS community but our collective future. As new developers start open source projects more will be compelled to choose more restrictive licensing models ( i.e. SSPL ), invest less in the community, and “control” as much of the code and product as possible. I will talk about the trend, talk about the common business models, and offer a few alternatives.

Then, a lot of factors leading up to today led to the environment changing very significantly, and today's community has some good groups in some areas, but not the kind of connected movement that existed in those earlier times. The speaker has been part of all of that development, starting off as a volunteer very early in the project, working on Mozilla staff for a few years in between, and still being part of the volunteer community in recent years. From that point of view, he'll bring up some ideas and suggestions on how this community can become stronger and grow again, so that a significant voice for the Open Web and the Mozilla Manifesto will hopefully be out there also in the future.

In a large-scale distributed scenario, efficiently implementing joins poses unique challenges as the data is usually spread around a cluster of machines instead of stored on a single machine. The goal of this talk is to illustrate the approach to implementing distributed joins in the CrateDB database that exhibits significant performance improvements compared to the existing algorithms. In the first part of the talk, we will cover the limitations of the nested loop and block nested loop join algorithms. The second part will show how the hash algorithm can work in distributed settings by addressing some of its memory limitations. Finally, we will introduce the distributed block hash join algorithm and how it enables CrateDB to analyze massive amounts of data 23 thousand times faster compared to the initial nested loop implementation.

DESCRIPTION:As research becomes more globalised and its output grows exponentially, especially in data, the need for open scientific research practices is more evident — the future of modern science. There is now a concerted global interest in open science uptake, but barriers exist. The formal training curriculum in most, if not all, universities in the global South do not equip students with the knowledge and tools to practice open science in their research or develop open-source tools.To work openly, collaboratively, and build a community, there is a need for awareness and training in using and developing open science tools. Through the OpenScienceKE framework, we developed a model to narrow the gap: the sensitize-train-hack-collaborate model. Using the model, we sensitised through seminars, trained on the use of tools through workshops, applied the skills learned in training through hackathons to develop open-source tools collaboratively. In this talk, I will demonstrate the need to Contextualize open source to ensure that no one is left behind, especially the Global South, and highlight some of our work in building an empowered community.

The effort resulted in the launch of two projects: Developers Italia and Designers Italia, which started a virtuous ecosystem involving administrations, businesses, and enthusiasts who want to improve public services and citizens' lives. Today, the two communities attract over 20.000 technical talents capable of contributing to their country's development and have created together hundreds of open source packages. We launched internationally at FOSDEM 2018, with the help of the Free Software community. We're returning four years later to provide updates, share lessons learned, and continue the conversation on how to make Italy the most hacker-friendly country in the world.

In order to meet the principle of least privilege, developers make rules for applications based on data flow and control flow of processes, such as SELinux and AppArmor. This step can be automated with secPaver. With the permission description of application, secPaver can generate security policy for different security mechanisms. By this way, security design can be simplified, and developers do not need to know many details about security mechanisms.
secPaver is a policy development tool that supports multiple security mechanisms. It aims to help users implement end-to-end security policy development, including visible policy design, iterative development, and policy release. It provides functions such as policy configuration, automatic generation, running test, missing rule gathering, and policy package export. secPaver shields security mechanism details and abstracts unified policy configuration file definitions and operation interfaces for different security mechanisms, improving policy development efficiency and reducing learning costs for developers.

The external tools and multi-cloud gateway providers add overhead to the latency and may not leverage full capabilities of On-Prem infrastructure. To overcome this, Ceph distributed storage, often handling petabytes of data, provides ways to move data directly from its OnPrem S3 RGW servers to multiple cloud providers, thus easing data movement.
In this session, we will briefly discuss about the CloudSync and CloudTransition features in Ceph RadosGateway (RGW) which can be used to replicate and migrate data to any external cloud providers.

The Foreman Project is planning to drop support for EL7-based deployments in Foreman 3.3, mostly due to the fact that EL7 is considered "feature complete" and there are no further updates (besides security fixes) planned for it.Contrary to Debian or Fedora, EL-based distributions aren't designed to be upgraded in-place without special tooling. This tooling exists in form of the LEAPP project for RHEL and the ELevate fork by AlmaLinux for AlmaLinux, CentOS, Rocky Linux, and Oracle Linux.We have developed a plugin for LEAPP that helps with the Foreman-specific parts of the migration, which we would like to present to you. As usual, there were a few challenges during the development, which will hopefully entertain you and maybe even help if you need to write own LEAPP plugins.And last but not least, we will also discuss other approaches you can take for the migration, if you do not want to upgrade in-place.

Both software-defined radio and FPGA are interesting. Especially, the combination of AD936X RF transceiver and ZYNQ 7020 level FPGA SoC is capable of running openwifi. Price has been keeping average DIYers away from this kind of platform as evaluation boards from ADI and Xilinx are both extremely expensive. Cheaper ones like ANTSDR exist, but seems all of them have tied the RF and ZYNQ chip together, so these are not suitable for generic ZYNQ development anymore.
In this talk, I want to introduce an openwifi capable low-cost AD936X extension board design and realization for the wildly available PYNQ-Z1 board by Digilent. This provides openwifi and PlutoSDR functionalities meanwhile keeping the major if not all functions of PYNQ-Z1 intact, with summed price potentially lower than all currently available openwifi capable platforms. Similar designs may also be applicable to other ZYNQ boards like ZYBO Z7-20 or Arty Z7-20, thus these could make openwifi available to much more people, especially those who already have a ZYNQ board. Besides this extension board, I'll also touch on tools and workflows for "modern" circuit board DIY, which enabled me to build this 4-layer board with BGA chip comfortably at home.
For more about openwifi, please visit the Free Software Radio devroom for "Opensource WiFi chip (openwifi) progress and future plan" on Sunday afternoon.

At that time I had little idea about Ada, programming or game development (nothing has changed about that to this day). But by September 2020 it had taken the early form of a Civilization clone. After more than a year of development, it has become almost a real game with its own features.

It helps users who have big volumes of spatio-temporal data, to explore it through analytics and geo-analytics views.
In this devroom we will use ARLAS to explore OSM data with an Analytic perspective. We will go through the following steps:- Download and index OSM data in a search engine (Elasticsearch) and make it available to exploration by ARLAS stack- Configure ARLAS dashboards based on this data and create analytical and geo-analytical views
We will be able to answer questions such as:- How many buildings are in the downloaded dataset? And how are they distributed geographically ?- What are the different existing types of buildings? With what proportions ?- When this data has been created/edited and with what frequency ?

Such a practice poses a variety of challenges in terms of website design and development ; but also and maybe more importantly, it asks for experimenting specific workflows for coordinating a variety of expertises ranging from social sciences disciplines (history, sociology, etc.) to data science, information design and web-related skills. It also reconfigures, for the research processes themselves, the relationships between activities of (data-related) enquiry and (communication-oriented) writing, creating a renewed space for discovery, invention and verification for the data sustaining a given argument or narrative.
Relying on recent experiments in making collective digital publications grounded in sociology of technology (https://medialab.github.io/carnet-algopresse/#/publication/en) and history of economy (https://medialab.github.io/portic-storymaps-2021/), this talk accounts for the diverse challenges arising from such activities of “data visualization-driven writing”, and some strategies we used to cope with them. It describes and compares the technical and methodological workflows we developed in order to simultaneously develop text, datasets and visualizations, taking into account a variety of aims, data materials, and distribution of skills. Doing so, it advocates for an extended understanding of the notion of “academic writing”, encompassing the practices of writing software, data and diagrams. Such an extended understanding, we argue, is necessary to design and develop writing workflows allowing to foster a multimodal and scientifically productive dialogue between these heterogeneous practices, taking full advantage of the web publication format as a research situation.

Its microkernel design has been evolving over the years and the project has not quite hit mainstream use. I believe this is due to one main reason: the lack of drivers for peripherals and hardware. In this talk, I explain how NetBSD kernel drivers have been reused in a microkernel setting and demonstrate their use to boot up a GNU/Hurd system via a userspace rump disk driver, with a driverless Hurd kernel, gnumach. The ACPI management, PCI management, and actual driver are in separate processes with RPC interfaces between them, which separates out their debugging, licencing concerns and execution. I believe this aligns with the original vision for the operating system, (as a Hurd of servers).

In ToroV, applications run as Virtual Machines without the need of an OS, unikernel nor device-model. ToroV combines a minimalist Virtual Machine Monitor and a virtualized guest program communicating through POSIX APIs. When the guest application requires to open or write a file, it just invokes the VMM using hypercalls. The VMM intercepts those hypercalls, processes the request, and returns to the guest. The sysadmin defines the ACL (Access Control List) of authorized hypercall per virtualized guest application. This allows the user to control the host’s surface that is exposed to the guest. In this talk, we propose to present the ToroV architecture together with several ongoing experiments. For example, the minimalist VMM allows us to boot up a VM in KVM in less than 6 ms. Also, we show how we debug guest applications by simply using GDB and the KVM API for debugging. During the talk, we discuss the main differences with unikernels and containers and how ToroV gets the best of both worlds. Also, we present the main differences with gVisor, which is a similar project from Google.

Traditionally, logs, metrics and traces have been considered the three pillars of observability, but more recently profiling has emerged as a fourth pillar to be used alongside these other observability tools.
Continuous Profiling, in particular, adds a dimension of time that allows you to understand your system’s resource usage (i.e. CPU, Memory, etc.) over time and gives you the ability to locate, debug, and fix issues related to performance.
In this talk, we'll present Pyroscope, an Open Source Continuous Profiling platform, explain the particular challenges it needs to tackle and showcase how it can be used to analyze and fix performance bottlenecks:

The main motivation behind the Container Object Storage Interface is to provide a similar experience for Object Store. Basic idea is to provide a generic, dynamic provisioning API to consume the object store and the app pods can access the bucket in the underlying object-store like a PVC. The major challenge for this implementation there is no standard protocol defined for object and the COSI project need to be vendor agonistic. For example, in the case of RGW, the application can request for S3 bucket and Swift bucket from the same ceph-cosi driver. Ideally, the Kubernetes resource for the bucket can be migrated to the different cloud if the drivers support it and the application can seamlessly continue with the same k8s object. It won't handle the orchestration/management of object store, rather it will be another client and provide bucket access on behalf of applications running in Kubernetes.A similar session was given in last FOSDEM'21, but the whole project went through design changes and will share that information.

Veracruz uses strong isolation technologies, such as AWS Nitro Enclaves, Arm CCA Realms, and the high-assurance seL4 hypervisor, to provide a safe, neutral ground, within which a sandboxed WebAssembly program executes.Recent enhancements to Veracruz have made it possible to support larger, more complex privacy-preserving computations: we have adopted the WebAssembly System Interface (WASI) as our programming model, which can be used by executing WebAssembly programs to query and modify an efficient in-memory filesystem, for example.In this talk, I will first introduce Veracruz before finally focusing on a real-world use-case for Veracruz, in privacy-preserving video object detection, developed as part of a collaboration between the Veracruz team and IOTEX, a manufacturer of IoT cameras.

It provides a statically typed API, dependency injection, modern persistence, structured logging and automation capabilities.
kalasim is designed for simulation practitioners, process analysts and industrial engineers, who need to go beyond the limitations of existing simulation tools to model and optimize their business-critical use-cases. In contrast to many other simulation tools, kalasim is neither low-code nor no-code. It is code-first to enable change tracking, scaling, refactoring, CI/CD, unit-tests, and the rest of the gang that makes simulation development fun.
In the talk, we will learn about its core concepts and study several examples from different application domains.

Also, its document format, while ASCII, is a bit cryptic, and contains extra information pertaining to the GUI (window and panel sizes, last modification date, etc.), making it inconvenient for placing in revision control.
A Domain Specific Language for generating GTKWave documents was developed, separating signal description and structure from style, not unlike HTML+CSS, but described using Python Lists and Dictionaries. This makes it especially suitable for embedding in Python-based Hardware Description Languages and Simulators.
While it fits my own needs, I'm hopping to gather some feedback on this tiny library, so it could be made more generally useful.

Understanding of these systems can help us understand the genealogy of the data generation. There are various applications that transcend from the basic understanding of geospatial as technological systems. I am analyzing OpenStreetMap and trying to define its digital spaces to understand what forms of plurality exist in data production. Conceptualization of Digital spaces of OpenStreetMap is important in order to visualise how we can define ethical boundaries and to answer the underlying question of “what is quality?”. I am currently interviewing, sending out questionnaires to OpenStreetMap users and conducting texture analysis of previous conference talks related to OpenStreetMap. In this talk I would like to present my ongoing progress on the research project OSM Utopia and present the small part in which I would like to increase the support from different researchers and practitioners, which is conceptualizing OpenStreetMap digital spaces.Furthermore, In this talk I explain how I planned to explore the interconnection and interdependence of analogue and digital spatiality of OSM and different research paradigms that needed to be explored. Also, will share the current progress on the way of defining digital spaces of OpenStreetMap and how we can categorise different analogues and digital assemblages that form these digital spaces. Limitations of these methods are also addressed. End goal that is targeted is that the data quality for OpenStreetMap requires a certain level of rethinking.

In this talk we assume the audience is familiar with the content of the previous presentation. One year later, we have executed many codes on AMD MI100 GPU, tuned the performance on various codes and benchmarks, utilized and tuned a few programming models such as HIP, OpenMP offloading, Kokkos, and hipSYCL on AMD MI100 and compared their performance additionally with NVIDIA V100 and NVIDIA A100 (including CUDA). Furthermore, a new open source software is released by AMD, called GPUFort, to port Fortran+CUDA/OpenACC codes to Fortran+HIP for AMD GPUs. In this talk we present what we learned through our experience, how we tune the codes for MI100, how we expect to tune them in the future for LUMI GPU, the AMD MI250X, compare the previously mentioned programming models on some kernels across the GPUs, present a performance comparison for single precision benchmark, discuss the updated software roadmap, and a brief update for the porting workflow.

Its interface with the untrusted software stack is a perhaps the largest attack surface that adversaries can exploit; unintended interactions with untrusted code can expose the enclave to memory corruption attacks, for instance.
We have proposed a notion, called orderliness, that embodies good practice set out by academic papers and the principles of the Intel SGX SDK’s programming model. It is concerned especially with these interactions between the trusted and untrusted worlds. This notion underpins Guardian: an open-source tool that we have created to help enclave developers check their enclaves are orderly before they are deployed. It automatically validates enclaves and reports violations to our notion of orderliness. These violations help find parts of their code that may need changing – they should usually point to an attack primitive.
We have found some security issues in enclaves that had been extensively vetted by other researchers – one of which was crafted by Intel engineers.

The majority of CVEs we encounter are due to memory safety issues and I'm here to talk about how a language like Rust is the way forward in avoiding those. Rust is a great programming language. It is a developer favorite and is rapidly gaining a foothold outside of systems programming. It has the potential to become a great general-purpose language with little of the overhead of traditional high-level general-purpose languages. Rust is fast, safe, and sustainable. Today I'm going to take you through the strengths and weaknesses of Rust and why it will be a great general-purpose language. Beware, I'll be doing comparisons with your favorite languages.

Let's be honest, JNI is not that secure and is controversial and it's high time we move away from it and adopt FFI like in many other modern languages. But is the new API enough or do we need to consider external libraries like JNA or JNR-FFI? I'll showcase some examples of using the new API with some of my other favorite languages.

While there are a plethora of sources for sample data and tools to import it, you can end up spending too much time finding representative data to work with. In our day-to-day work at Timescale, we often need to quickly create lots of sample time-series data to demonstrate new features, run a benchmark, or help community members with examples as they learn.
Although using real application data would be ideal, PostgreSQL provides the generate_series() function which makes it easy to create a representative time-series dataset using varying cardinalities and different lengths of time.
In this talk we'll introduce generate_series() and demonstrate how to use it to create realistic-looking time-series data of all shapes and sizes, using custom PostgreSQL user-defined functions. Once we've mastered the basics, we'll dial it up a notch by incorporating PostgreSQL math functions and relational data to create realistic time-series patterns of data for various use cases like sales or website visits.

Once deemed near-impossible to emulate in real-time, we now celebrate the 10th anniversary of its most popular emulator: RPCS3, a free and open-source software capable of running two thirds of the console's catalogue on PC.
This talk describes the hardware and software stack of the PlayStation 3, covering the IBM Cell/B.E. CPU, Nvidia RSX GPU and Sony's CellOS operating system in detail. We compare these against earlier and later consoles, explaining how their design and complexity has shaped a new generation of emulators and binary translators, before delving into the history and internals of RPCS3 and other PlayStation 3 emulators.

DESCRIPTION:Fuzion is a modern general purpose programming language that unifies conceptsfound in structured, functional and object-oriented programming languages intothe concept of a Fuzion feature. It combines a powerful syntax and safetyfeatures based on the design-by-contract principle with a simple intermediaterepresentation that enables powerful optimizing compilers and static analysistools to verify correctness aspects.
This talk will focus on Fuzion's aspects related to safety-critical softwaredevelopment. A fundamental idea of Fuzion is to provide a simple language at ahigh level of abstraction and move implementation decisions from the developerto the compiler. To enable this, the language defines a simple but powerfulintermediate representation for static analysis tools to operate on.
Furthermore, pre- and post-conditions for design-by-contract are provided in away that enables different levels of verification: static analysis as well asdynamic checks at different levels from safety to debugging.
Fuzion does not support exceptions, a run-time error has to be part of the resultof a call and must be checked explicitly. Fuzion does not support dynamicloading of code. Numeric operations such as 'infix +' check for overflow.
Fuzion applications consist of a set of library modules and a main modules.Modules are verified for correctness individually as well as wholeapplications. This is possible since dynamic loading of code is not supported.

The IETF has started to look into WebRTC for that, starting from ingestion using the WHIP protocol. This presentation will introduce WHIP, some existing implementations, and how this could be expanded to distribute streams to a wide audience via WebRTC as well.

This requires a significant infrastructure: Koji/RPM builders, Angular-based WebUI, Gitlab forge, network and RPM package dependency management, Qemu test lab management, all need to come together and be connected, in a mix of Qemu virtual machines and LXC containers. Fortunately, Ansible and Proxmox comes to the rescue to manage this complexity.
In this talk, we'll present our architecture of a self-contained CI/CD environment in the cloud, to cross-build RPM packages and Linux images. We will then dive into the specifics of using Ansible to drive Proxmox and deploy a mix of Packer-built Qemu virtual machines and LXC containers. Those provide a full Koji build system (hub and builders), an Angular frontend, Go backend, a Gitlab forge as well as network isolation/firewalling and a Qemu virtual target lab.We'll continue with lessons learned from doing these deployments for multiple customers. We will finish describing solutions we are currently working on, like Ansible AWX, to address the challenges of doing it at scale and increase automation.

Historically the network has been made up of newly written native Matrix clients, or bridges to 3rd party existing chat systems (e.g. Slack, Discord, Telegram).
The matrix-rust-sdk is a modular Matrix client library, meant to be a robust implementation of the protocol, and to make even the most advanced features such as E2EE easy to use.This talk will walk you through the design decisions and the tradeoffs that come with it, give you an overview of where we're at and where we're going with Web-Assembly, and finally what the future holds for the matrix-rust-sdk. Finally it will be connected to a real-life example of software using the matrix-rust-sdk: Fractal-Next.

However, during the last years, WebAssembly is finding its way also outside of the browser because of the many benefits it provides like portability, security and flexibility. We think WebAssembly can be leveraged by Kubernetes in many ways. This short session will focus on how WebAssembly can be used to write Kubernetes admission policies. We will show an open source Kubernetes Dynamic admission controller that uses policies written in WebAssembly to validate and mutate the requests made against the Kubernetes API server.

To be specific: Distros have been reduced from being the universal FOSS product that delivers a complete solution to the user, to a set of very nicely maintained “free beer” types of repos full of packages that make up application building blocks for custom stacks packaged with Docker. The good news is that distros did not fail to deliver the spirit of FOSS as badly on the desktop and server side as they have for embedded Linux.

Being a long standing project, it has inherited a number of quirks and features that -at the time of coding- made sense. The datasets had different sizes 10-20 years ago and the cost model is not always accurate for current workloads.
Thus, there is now an ongoing effort to significantly improve the calculations that the MariaDB Optimizer is doing. With the addition of JSON Histograms, the range optimizer is one of the most impacted modules. The end goal of this effort is to provide the user with a better query optimizer, but also put the user in control and allow the user to tweak many more parameters than were previously available. In this talk I will go through the major changes that are upcoming in MariaDB, changes that could impact query performance (for the better) and also raise awareness about which parameters have the highest impact on query optimizer performance.

Common examples of such predicates are orientation tests for 2D or 3D points. If these predicates are evaluated for floating-point coordinates, they can yield incorrect results due to round-off errors, which can cause algorithms to fail or to return invalid constructions. This talk presents a C++ template metaprogramming implementation of fast, robust floating-point predicates, which guarantee correct results without severe performance penalties.

Do you feel like you need to change your tech stack continuously?
If the answer is yes to both of the questions, join my talk about the solutions I’ve found so we can ca discuss your best practice as well.
Accelerators (technology kits) are opinionated yet pragmatic that I’ve identified and tested on the projects in production.They allow me to go faster on delivering high-quality code with an easy to master architecture, to on-board other team members on the project and increase their productivity without reinventing everything from scratch.
We will discuss about the main JS frameworks (Vue.js, React, Svelte, Angular) and their meta-framework (why use them?), the state management (local and server state), the accessibility (how to integrate it from the beginning?), the testing and styling (CSS, SCSS, CSS-In-JS, Tailwind, which one to choose?).
Of course, take everything that will be said in this talk as an opinion, not as an absolute word because there is only one way to develop.
Be ready to share your tips during Q&A session.

As a result, new languages are often engineered (or "over-engineered") for that glorious future where millions of programmers spend their lives working with the language, and a small army is maintaining the compiler and related tools. But how would you design a language that assumes this bountiful future will never arrive? A language that, even in the best of circumstances, will always be obscure and secondary? Futhark is a programming language designed for a very specific domain: high-level, deterministic, data-parallel number crunching. It explicitly disavows general-purpose use, and it is absolutely not possible to write full applications in it. Thus, even if Futhark somehow managed to become the largest conceivable success and completely dominate its domain, that would not translate into very many programmers. And even then, it would at best be a secondary or third language for most of its users.
In this talk I will talk about how such a perspective has affected the design of the Futhark language and its tools. To a first approximation, this is just the "principle of least surprise" applied to every part of the language and ecosystem. As a niche language, Futhark's novelty budget is quite limited, and its users will not have the inclination to learn about syntactical subtleties, elaborate package managers or build systems. At the same time, it's trying to innovate in a challenging domain, so some things definitely will have to be novel. Balancing these concerns has been interesting, and my experiences are perhaps even useful for designers of languages, tools, or systems in similar situations.

However, the CVE Binary Tool is a tool which has been designed to analyse and trace dependencies by performing a binary analysis that attempts to detect the versions of the libraries in compiled applications in order to determine the vulnerabilities that may be present. Since the tool was initially released, the number of libraries which can be detected has steadily increased so now over 100 libraries can be detected primarily through the effort of students working under the Google Summer of Code (GSOC) programme. Supported libraries have typically been prioritised based on the number and frequency of vulnerabilities reported in the CVE database. The latest version of tool released at the end of 2021 has added capabilities to perform vulnerability scanning of Linux distros, Python applications and to consume Software Bill of Materials (both the SPDX and CycloneDX formats are supported). Further enhancements are planned in 2022.
This presentation will describe how the tool works, how to use it in a number of use cases and show how you can contribute to further develop the capabilities of the tool.

Managarm is a pragmatic microkernel-based OS with a focus on asynchronous operations. The talk covers various aspects of the microkernel, such as its IPC model, resource management, and user space API. Managarm's microkernel employs a capability-based design to manage hardware resources. In contrast to current mainstream OSes, Managarm's system calls never block but report completion asynchronously whenever possible. This includes system calls for common tasks such as memory management or inter-process communication (IPC). A lock-free ring buffer is used to quickly deliver asynchronous completion notifications to user space. Managarm implements a POSIX subsystem to be able to run various well-known UNIX applications (e.g., a Wayland desktop) on top of the microkernel. This subsystem is implemented entirely in user space. The kernel uses various acceleration strategies to to efficiently support this use case.

DESCRIPTION:French citizens have a right to request source code developed by their administration. This includes source code developed by public research labs. But the research sector has a distinct place in the "public code" landscape. It produces open source gems like scikit-learn, and many researchers contribute to Free Software, but some source code is never published because public labs are requested to use them as assets for new startups. This talk will explore this distinct place, the work that has been done in France to promote the publication of research source code and the challenges ahead.

DESCRIPTION:DirectFB2 is a fork of DirectFB, a graphics library designed with embedded systems in mind that was widely used in the GNU/Linux embedded world. DirectFB2 comes with changes such as a Meson build system, a pure C implementation and a modularization of the source code.
Access to the low-level display is based on a DRM/KMS system module (or possibly on a legacy Framebuffer system module), and depending on the platform, hardware-accelerated graphics rendering can be achieved using the architecture of the GFX driver modules.
The core library is very light (no external dependencies) and provides basic font/image/video rendering support which can be demonstrated with the DirectFB-examples.
The use of additional DirectFB providers based on external libraries is also possible thanks to the DirectFB-media package, such as rendering fonts with the FreeType library, rendering images with libpng or jpeg libraries, rendering videos with FFmpeg or GStreamer libraries.
For 3D graphics, OpenGL or Vulkan rendering can be done with the DirectFB graphics backend. As an example, the Mesa 3D implementation makes OpenGL rendering possible with a DirectFBGL module or with EGL for the DirectFB platform, and the SwiftShader implementation makes Vulkan rendering possible with the DirectFB WSI.
This talk aims at getting started with DirectFB2 which may be worth considering on some devices.

The constant pressure to move DATA in containers and Kubernetes is creating a lot of confusion and misunderstanding.
This is particularly dangerous when talking about Relational Database Management System.
MySQL, as well as Oracle, Postgres or SQL Server, is a RDBM, as such subject to the erroneous interpretation caused by this new crazy shining things that will solve all.In this short talk we will clarify, that first of all, we are not looking to something new and second why we need to be very careful when talking about using Kubernetes and containers for RDBMS.
REST, the architecture underlying the web's protocols, has proven its benefits in creating a globe-spanning, decentralized information network. However, REST is showing its age - it was designed when surveillance capitalism, identity theft, information warfare, and other threats were largely hypothetical concerns. Unavoidably, REST leaves many of these issues unaddressed. Best practices fill some gaps, but may not be universally adopted.
The Interpeer Project has been awarded a grant from the Internet Society Foundation for research and development into a next generation architecture that addresses current and future Internet user needs. Such an architecture needs to embrace the strengths of REST, incorporate known best practices, but ideally make worst practices impossible.
This talk presents the issues with REST in some detail and lays out proposed solution sketches. The ideal is to invite participation, however. The 'net needs a wide range of view points to be fixed.

With the ever increasing data storage and query requirements, new challenges are brought forward for horizontal elastic expansion and security of the PostgreSQL database.How to provide existing PostgreSQL databases with incremental capabilities such as data sharding, data encryption and other functions is of great concern to many PostgreSQL users.This session will focus on introducing how to empower PostgreSQL thanks to the ecosystem provided by Apache ShardingSphere - an open source distributed database, plus an ecosystem users and developers need for their database to provide a customized and cloud-native experience. ShardingSphere doesn't quite fit into the usual industry mold of a simple distributed database middleware solution. ShardingSphere recreates the distributed pluggable system, enabling actual user implementation scenarios to thrive and contributing valuable solutions to the community and the database industry.The aim of ShardingSphere is the Database Plus concept.

However, actually contributing as someone not familiar with the project, its workflows and its tools is usually everything but simple and requires a substantial time investment. This is especially the case if you are not a programmer or not as experienced with the technology in use, which can ultimately discourage otherwise potential willing contributors.
This talk will illustrate concrete steps that you, the maintainers of Open Source Projects, can undertake to simplify the hoops one has to jump through for their first contribution. We will cover various tools that you can use for this, be it for communication, localization, editing or publishing, how to provide good introductory material and how to build a welcoming atmosphere.

Early works such as the Xoar architecture demonstrated the need for virtualized environments to begin with a lightweight, restricted bootstrap from which isolation of PCI management could be established. Since that time, knowledge of real IOMMU implementations and how to leverage them for system integrity has evolved. In this presentation, the new Hyperlaunch capability for starting hypervisors will be presented with a short discussion of the Xen implementation. The talk will progress to a discussion of how Hyperlaunch is connected with TrenchBoot (Linux Secure Launch) and Mandatory Access Control communication fabrics. With a focus on how it enables dedicated PCI management constructs that can provide secure and trustworthy isolation for PCI devices, with the potential for CXL devices. The talk will close with an open discussion on how hypervisors might unify around a common approach for IOMMU management.

So, I had to talk many of the background knowledges to the students as an 'introduction' so that students could understand the OSS licences with compliances with ease. Fortunately, there were good feedbacks from the students, though, I need to improve my lecture more gathering more use cases etc.I will give a talk my experiences there at the university and discuss how to improve my lecture to teach such 'licences and compliances' to students. the feedbacks/ideas for my talk are really welcome!

LLVM being emerging compiler framework, there was some gap to be bridged w.r.t. Fortran language debug info generation. This is because Fortran language has few features which are very powerful, as compared to other languages.
Fortran dynamic arrays are one such powerful language feature. There are variety of arrays like adjustable array, assumed shape, assumed size, assumed rank, allocatable and pointer arrays. LLVM generated debug info was not sufficient to debug these many variety of arrays with GDB/LLDB. The LLVM was lacking support for multiple DWARF operators (DWOPpushobject address, DWOPover), DWARF attributes (DWATdatalocation, DWATallocated, DWATassociated, DWATrank) and a DWARF TAGs (DWTAGgeneric_subrange). Other than these, existing support for DISubrange was not sufficient to handle Fortran arrays. The same was true for Fortran strings which is not mere pointer to character type and needed more support from LLVM. Other features which needed similar LLVM support for debugging were Fortran modules, namelist and signed constants etc.
All these enhancements made in LLVM are as per DWARF4 or DWARF5 specification for the Fortran language. These enhanced debug info are used by GDB/LLDB and user debugging experience is improved now while handling these Fortran features with GDB/LLDB. In order to make use of these enhanced debug info emitted by LLVM, GDB/LLDB is also enhanced in cases where required. With these enhancements added now in LLVM, Fortran program debugging experience with the clang/flang emitted programs are on par with gcc/gfortran emitted programs and in some cases it’s even better than gcc/gfortran.

As an 'ingredients list' of files, package dependenciesand other artefacts that a piece of software is made up of, SoftwareBill of Materials are becoming an essential part of modern softwaredevelopment practices.
Open source software provides great transparency and can yield rapidvulnerability patching, but this is too often compromised by sprawlingdependency trees which make it difficult to find vulnerable componentsin larger software projects. With SBOMs, there's a way of effectivelycataloguing software components and the package metadata needed to checkthe integrity, pedigree and provenance of software supply chains. Thistalk will cover the benefits of having a common standard for creating,sharing and consuming Software Bill of Materials, what SBOMs should andshould not contain, and how to use SBOMs to inform security measuresacross the diverse range of package ecosystems.

By being light, simple, and cheap, bicycles confer huge amounts agency to their users. 'Web3' doesn't have a lot of bicycles.
Instead it's got a lot of hyperloops: slick, complex, expensive, and with very little application.
What can we learn from bicycles when we design new tools for the web? Earthstar occupies a relatively unexplored band of the contemporary web3 spectrum: ephemerality, lightness, offline-ness, malleability, and serving groups of people who already know each other.
This project was funded through the NGI Assure Fund, a fund established by NLnet with financial support from the European Commission's Next Generation Internet programme, under the aegis of DG Communications Networks, Content and Technology under grant agreement No 957073.

DESCRIPTION:The CHAOSS project represents a potential force for power and good in open source and is demonstrating significant progress toward its stated aims during its first four years. In particular, the CHAOSS project advances the development of metrics and programs that can help other projects to first understand their own diversity, equity, and inclusion and second work to improve their project in these areas. This roundtable includes speakers who took part in a year-long reflection on DEI practices within the CHAOSS project. The roundtable talk will help other open source projects in their work towards improving diversity, equity, and inclusion by exploring practices within the CHAOSS project first, then using those examples as points of reference for other projects. In particular, the roundtable talk will advance these goals, aimed at answering the question of: How do we design open source communities to be more diverse, equitable, and inclusive?

Unikernels cannot be easily administrated or monitored? While unikernels have the potential to revolutionize our infrastructures and take cloud computing into the next era, many worry that unikernels cannot be seamlessly integrated into today’s development and production workflows.At the Unikraft team, we are heavily working on addressing these concerns and changing the status quo. Although unikernels are monolithic bundles of only necessary kernel functions and an application, we follow the concept that everything is a (micro-)library. Users can pick and choose kernel functionality at build time. The same applies for monitoring and debugging: In this talk, we will give an overview of our current debugging and monitoring capabilities, and we will present our vision for how these pieces will enable a cloud-native experience. We will also give a deep dive into our GDB backend implementation with a live demo.

It was built on open data and open source libraries. But what separates it from the rest is not code - but experience. Maps on mobile screens are hard to do properly, and there's always a temptation to add another screen, another button. Turns out you need a bit more than skills to make a perfect app: at least you need to use it daily.

Arguably small syntax sugar additions combine for the programmer's comfort, like for example user-defined literals and container aggregates, that allow natural initialization of user-defined containers with the same expressions used for basic arrays since the beginnings of Ada. In this talk, I discuss how these features allow the initialization of a container data type for heterogeneous values (a-la JSON) without the need of crutch functions (like the usual "+"). Such an structure could be used for compiled-in definitions but, more ambitiously, a relatively simple parser for a strict subset of Ada could leverage this data structure for natural-looking (to the Ada programmer) configuration files. Such configuration files could be useful for tools that are strictly Ada-oriented, written by and for Ada programmers.

However, there is nothing worse than writing a lot of boilerplate code just before even start implementing those features. In this talk, you will learn about Flutter code generation tools and various tips on how to avoid implementing boilerplate code and focus on your next-gen project.

Do you know the implications of adding elements to an slice, or new keys to a map?
Do you know why you can’t relay in maps order? Do you know how channels handle the buffer or the blocked goroutines? If you don’t know about that, this is your talk. I going to access the go runtime memory state of the maps, slices and channels, and show you how they evolve over time while we change them.

It is built using reactjs on the top of matrix-js-sdk.
The main focus behind making Cinny is to have a client that is simple, elegant and doesn't feel heavy on end user. Cinny was launched publicly in end of July 2021 and since then it has matured a lot. Cinny has support for end-to-end encryption with options to import and export encryption keys. It also has basic support for Spaces (coolest feature of Matrix). Cinny also has ton of other features most notably full UIAA (User-Interactive Authentication API including SSO Login), carefully crafted themes, Rich replies, Reactions, Markdown and the list goes on.
Our roadmap also includes some other great features in near future; such as room settings, full support for spaces and later a responsive interface that also support mobile screens. We are also working on standalone app of Cinny using Tauri (exciting thing here is that app size is considerably less and doesn't require to have chromium to work).

Additionally, open-source allows for reconfigurable expertise, or the ability to combine people from different backgrounds in ways depending on the task at hand. This talk will discuss the challenges associated with spontaneous interdisciplinary, in addition to opportunities provided by reconfigurable expertise. Examples from three open-source communities: OpenWorm Foundation, Rokwire Community, and the Orthogonal Research and Education Lab. The community building aspects of maintaining members for this type of adaptive and resilient resource are also addressed. When applied to academic-based communities, the ability to reconfigure working groups based on both the immediate and long-term needs of expertise is a valuable model for project management.

Data science and machine learning offer a unique opportunity to empower scientists in LMIC by providing cost-effective tools ideal for underfunded settings, but there is a gap in accessibility, infrastructure and skills that must be bridged before these tools can be effectively implemented.We are developing the Ersilia Model Hub, a FLOSS platform where scientists can browse through a catalogue of AI/ML models and run them without the need to write a single line of code. The platform features both models published in the literature and models developed by us on-demand or in collaboration with researchers in LMIC. The pilot tool focuses on models for drug discovery in infectious and neglected tropical diseases, but we plan to expand to other global health.

This means they inherit Matrix's nice properties, including E2EE, decentralization, and user control.
Under the hood, the apps use Collabs, a TypeScript library I'm developing. Collabs provides collaborative data structures - specifically CRDTs. These are classes that have APIs like ordinary data structures (Map, Array, etc.) but also automatically sync between clients, guaranteeing eventual consistency. I will briefly describe the unique features of Collabs and show what it's like to program an app using the library.

However, error messages and general logging can leak sensitive data, and in some cases even compromise your whole stack, as developers worldwide have recently learned from the log4j vulnerability.
With Confidential Computing, the world gets much more complicated, as every piece of information that a malicious entity on the host (including the host itself!) can gather may be leaking vital information about your workload. This talk details some of the problems that arise, and discusses some options to address them whilst considering real life workloads and application lifecycles.

It is driving the industrial revolution and digital transformation of our world. This history is composed of many events related to conceptual and technological breakthroughs. In order to help in the analysis (by researchers) and explanation (to citizens), the NAM-IP Computer Museum is actively developing the "Trajectware" Open Source framework based on a the structuration of illustrated events in the form of timeline fragments that can be explored using various navigation operations to focus on specific periods, aspects (technological, conceptual, cultural, contextual,...) or the involved people/organisations.
This talk is intended to everyone. It will first present the global design based on (1) a knowledge base back-end inspired by different ontology standards (SEM, DOLCE/Spatial History Ontology, Constructed Past Theory, DBPedia) and accessed through queries and/or a specific API to extract a relevant timeline, and (2) a navigation front-end, currently based on ReactNative. Different timeline navigation features will be illustrated on a concrete application case: the "micro-computer, meg@ revolution" exhibition of the NAM-IP museum.
Through our presentation, we hope to trigger interesting discussion about our current work and to gather suggestions and interests to grow this project !

Linux is a fairly obvious choice to build these product that have greaterthan 128MB of RAM and storage. On resource-constrained devices, an RTOSsuch as Zephyr is able to even run on devices with as little as a fewhundred KB of RAM and storage.
However, the kernel is a small part of the device's software stack - thereis middleware, application frameworks, security policies, key management,OTA and multi-year maintenance that the company needs to budget into thedevice's engineering support costs.
Viewing the Linux and RTOS ecosystems as two parts of a single productplatform allows for a coherent view of both ecosystems by developers. Youwant to make sure that you can apply the same set of softwareconfigurations and policies across both ecosystems e.g. library versions,compatible protocol suites, security configurations, OTA mechanisms andeven a single set of IP compliance tools.
As an example, when you decide you want to secure all your networkcommunications out-of-the-box in your product platform, you need to:
Now repeat this exercise across every key component of the OS - securitypolicy, networking features, OTA, toolchain hardening, IP compliance toolsand you end up with a meta-project that spans and contributes to bothecosystems.
We've started to build such a open product platform with opinionateddefaults that follow community best practices with Eclipse Oniro. Andthis is our story about our plans for the future.

On the flip side, if your database often gets updated, keeping your materialized views up-to-date can be challenging. Especially when working with time-series data where timeliness is often an important requirement.

XWiki has pioneered wikis by including structured data on the same level as free text content, thus enhancing significantly the expressiveness of the built knowledge bases; this same usage is also popularized by Confluence and Notion, with different user experience choices and more importantly with business models that are keeping user's data locked-in on the Cloud or in proprietary software.
In this talk we will present XWiki's journey to provide the best FOSS alternative to proprietary knowledge management tools, based on both current features and future roadmap.
We will showcase XWiki's approach for collaboration on text & structured data, including the newly conceived "livedata" component for inline editing of structured tabular data as well as the new realtime editor based on the realtime editing technology from CryptPad.

Unikernels represent a compile-time specialization strategy and leverage the joining of user and kernel space via a library Operating System in order to achieve this, offering as a result incredible runtime performance whilst increasing application security via isolated hardware virtualization. As Unikraft, an open-source unikernel SDK and library Opeating System toolkit, has grown over the last few years, the number of available off-the-shelf applications, interpreted languages, libraries, target hypervisors and architectures has grown significantly. In order to ensure consistency between builds, prevent bugs and performance regression, and to allow for new features, a massive effort has been undertaken to facilitate massive build permutations of specialized unikernels which target and include variations of this growing ecosystem based on new commits and Github Pull Requests. In this talk, we discuss the journey of this undertaking, highlight and demo several CI/CD solutions in this space with Concourse, and how we are continuing to expand the ecosystem to automatically and intelligently build unique additional performance-oriented permutations from configurations available in the underlying libOS.

These solutions often use a broad range of technologies and algorithms that each have their advantages as well as limitations. Existing open source positioning solutions often offer a complete package for indoor navigation or asset tracking that allows developers to set up a specific application with minimal effort. However, these positioning solutions offer little room for developers to customise them.
OpenHPS is an open source hybrid positioning framework for creating a positioning system without being bound to a specific technology or a set of algorithms. Developers are free to choose the data they want to use, from where they want to obtain this data, how to process the data and finally how to use the outcome of the positioning system. In this presentation we will present the modularity and ecosystem around the OpenHPS framework, some technical aspects as well as the current state of the project.

Out of an estimated 11–21 million cases of typhoid fever and 200,000 deaths occur worldwide each year. Other elements contribute to this situation and particularly in rural areas where patients to doctors ratio is very low, lack of medical facilities and costly tests. There are a number of tests available presently, from molecular to immunological and biochemical to microbiological. However, Users are unsatisfied due to delays in getting test results and Imprecise diagnosis. Misdiagnosis is usually experienced since most health care facilities use only Widal test without confirmation of results with a second test method. In addition, the diagnosis of Typhoid involves several levels of uncertainties. Patients cannot tell exactly how they feel, doctors and nurses cannot tell exactly what they observe. There is therefore, an urgent need to develop a rapid, highly sensitive and cheap diagnostic tool for diagnosis of typhoid fever.

The past two years have been exceptionally trying. Any guesses as to why that is? :)
In this session, I will share our experiences from the 6 online Ansible Contributor Summits that we have held through 2020-2021. While the virtual platform gave us more flexibility in many ways (such as having 3 events in a year instead of the usual 1), it definitely presented many new challenges as well. From pre-event marketing to technologies used during the summits, post-event surveys + feedback that feed into the next event, it's a continuous cycle of trials, errors, and improvements.
There is also a major shift towards using open source tools and workflows for the summits, at the request of some community memebers as well as the desire within our team. I'll share what fell short and what thrived, and how the changes impacted not just conference management for our team, but also how the Ansible community received these events. Because at the end of the day, these conferences are for the community contributors and participants!

The simplification of IaaS appears ideal (in theory) but providers and users are presented with several challenges: providers aim to reduce infrastructure maintenance overheads; users require isolation, flexibility and programming freedom.
Serverless deployments are mostly backed by sandboxed containers. To enable programming freedom for users, providers allow the use of containers for function deployment, however, to ensure strict isolation, these containers are sandboxed in VMs. As a result, this bloated stack brings complicated maintenance costs: (a) several layers of abstraction between the user function to be executed and the actual execution environment; (b) increased attack surface; (c) increased request-to-exec time; (d) reduced set of feature availability for functions (hardware acceleration).
Unikernels promise fast boot times, small memory footprint and stronger security but lack in terms of manageability. Additionally, Serverless frameworks only support containers. Moreover, unikernels provide a different environment for applications, with limited or no support for widely used libraries and OS features. This issue is even more apparent in the case of ML/AI workloads. ML/AI libraries are often dynamically linked and have numerous dependencies, which directly contradict the statically linked notion of unikernels. Finally, hardware acceleration is almost non-existent in unikernel frameworks, mainly due to the absence of suitable virtualization solutions for such devices.
In this talk, we present the design of a flexible serverless framework designed for the cloud and the edge, backed by unikernels that can access hardware accelerators. We go through the components that comprise the framework and elaborate on the challenges in building such a software stack: we first present an overview of the necessary components of a serverless framework; then we focus on the function execution framework based on two popular unikernel frameworks; finally, we present a hardware acceleration abstraction to expose semantic acceleration functionality to workloads running on top of this framework.
A short demo of the working components will be presented, discussing the challenges and trade-offs of this approach.

Newly structured as a 501c3 non-profit, OST2's core goal is to provide free and open training that helps increase system security. This can take multiple forms, such as training dedicated security engineers, training developers to write more secure code, training potential contributors to security-focused projects, or training engineers on safer alternatives to technologies they're already using. In this talk we'll describe current and future examples of all the previous use cases, and drill deeper into a case study of how 3mbdeb, a licensed service provider for the coreboot open source firmware project, is contributing to OST2 to advance the state of open source firmware security.

More specifically, Decidim is a web environment (a framework) produced in Ruby on Rails (a programming language) that allows anyone to create and configure a website platform to be used as a political network for democratic participation. The platform can be deployed by any organization (local/regional/national governments, associations, universities, NGOs, or cooperatives) to host large scale citizen participatory processes for strategic planning, participatory budgeting, public consultations and collaborative policy-making. The project was launched in 2017 in Barcelona and, 4 years later, there are more than 400 active instances of Decidim around the world. In this talk we will present the lessons from this outreach process advocating for a radical model of participatory democracy in contexts as different as the Helsinki City Council, the Mexico City Government, the New York City Commission on Civic Engagement, the French National Assembly, the Italian Government or the European Commission.

Now used by the ham radio community, we consider how hellschreiber is emitted using a Raspberry Pi GPIO pin configured as radiofrequency emitter, an approach made popular by rpitx and generalized to GNU Radio with our gr-rpitx OOT sink block (https://github.com/jmfriedt/gr-rpitx). The transmitted signal is recorded by a RTL-SDR DVB-T receiver and decoded using gr-hellschreiber (https://github.com/tlavarenne/gr-hellschreiber).Preparing this presentation was an opportunity to become familiar with GNU Radio 3.9 and the presentation concludes with some of the challenges (and solutions) met when porting gr-acars(https://sourceforge.net/projects/gr-acars/) to this new version of the signal processing framework.

But...what do you do with it? How does user feedback correspond to issues in the backlog? How do you get the wider OSS community team up to speed if they haven’t been part of the synthesis process? These are some of the questions you may ask yourself after participating in user testing or usability testing. You’re ready for a synthesis process!
The USABLE team has already published two resources about user testing and usability testing, now they are presenting their third resource about user insight synthesis. You’ll see how they supported open source software tool teams to work with user insights in an open source way of user testing, usability and synthesis work.In this session you will observe how the USABLE team supported OSS tool teams with user insight synthesis processes with detailed explanations of why, how and when to do synthesis. You will also view clips of a previous closed session in which the USABLE team and OSS tool teams collaborated on a synthesis work session.

We protect our servers, encrypt filesystems and/or datafiles. But what about log files? And especially log files that contain actual data such as the MySQL binary or relay logs. These are technically called log files but they contain the actual data going through your MySQL systems for replication purposes. I will describe how you can enable and use them and also, in case of disaster, how you can recover your encrypted binary logs so you can use them for point in time recovery.

Kubernetes holds a promise to enable automation and process improvement directly contributing to a system's reliability. Establishing a declarative API and providing a cheap and disposable environment, Kubernetes makes it easy to create uniform experiments, which may run manually or be exercised multiple times over the development cycle through a CI/CD system. Despite their abundance, existing benchmarks and Chaos engineering tools work in isolation, thus restricting the complexity of testing scenarios we can build.
This talk will present Frisbee: an automated suite for the unified testing of distributed applications over Kubernetes. Frisbee simplifies a series of time-demanding activities, including the spin-up of the dependency stack required to bring the system into a steady state, the combined execution of workloads and faultloads, and the validation of the system's behavior via test cases. We will demonstrate Frisbee through a series of tests, focusing on uncertainties at the level of application (e.g., dynamically changing request patterns), infrastructure (e.g., crashes, network partitions), and deployment (e.g., saturation points).

However, it is a fundamental institution in security provisions in today's socio-technical societies. But it remains impossible to harmonize the transnational Open Source system with sovereign systems: both cannot be clearly mapped to each other. Yet, international arbitration provides a type of remedy that already exists in software development, illustrating how a shift from just fighting bugs to mitigating architectural flaws can look like.

Each app connecting to its own server on its own schedule, perhaps using inefficient technologies, can cause a lot of battery drain. Push Notification services are systems that can route all the important updates our devices need - whether they're instant message, VoIP, or social updates - into one shared channel.
Unfortunately, the status quo in push notification services rely on centralized, proprietary services hosted by a third party. UnifiedPush is a set of free and open source specifications that allow you to get push notifications while picking your own hosting provider. This presentation goes over the history of UnifiedPush, current state of the project and architecture, and what the future goals of UnifiedPush are. It also discusses push notifications on Linux phones.

Countless links emerge and die off every minute. Each of us have our own habits and patterns across it. Our browsing is increasingly complex, so it makes no sense why we're still using technology based on filing cabinets -- tabs, files, folders. Quark is the DWeb browser x social platform that shows you paths across the internet. Imagine if you could bump into someone else looking at similar content/search results, see where they've been, and tag along to discover content together.
In this presentation, I'll share use cases for The Quark Browser, as well as how this tool can address the existential crises of the siloed Web 2.0 internet by making the internet more serendipitous, visual, and communal.

It greatly enhances your ability to write complex user facing software and control systems.
Broadly speaking, it belongs to the category of libraries which includes Redux, MobX, Rx (Reactive Extensions), and XState.
It works by providing a new unit of composition which we call the behavior. Behaviors are simple blocks of code together with their dependency relationships.
We developed Behavior Graph to address our own complexity challenges while building an iOS video playing library which is used internally throughout the suite of native Yahoo mobile apps. After years of development and production usage, it has proven to be incredibly competent at scale.
We have since ported it to multiple languages including Javascript/Typescript. It is less than 1500 lines of code and contains no external dependencies.
Behavior Graph should appeal to anyone with an interest in software architectures and willingness to rethink how we write software applications.

If we think of computing devices as programmable tools for active exploration, how should they look like? What programming model should they be based on? It's fair to assume that it shouldn't look like what passes for regular programming nowadays, since that is clearly out of touch with users. Perhaps something more... declarative? ...minimalistic? So, how can we bring declarative and minimalistic computing to the masses? And... maybe we have already?

The model that has been chosen in VPP to provide up to date statistics is built upon shared memory and optimistic locking.The counters are updated in this shared memory at a rather low cost by the data plane and can be read out at almost any time by all the consumers.We will first describe this model in more details.
The consumption of these stats may take various forms depending on the use case and the application needs.That's why we have developed different high-level components to access them:
1) A filesystem in userspace: thanks to go-fuse, we can mount a filesystem ordering statistics in folders and files, in a similar fashion to '/proc' in Linux
2) A Prometheus agent: applied to Calico/VPP, a new dataplane for Calico - the popular cloud native Kubernetes network plugin - based on VPP. Prometheus is integrated as a monitoring tool in order to export our statistics in the form of real-time metrics collected from targets. Metrics come from our pod interfaces statistics, and targets are Calico/VPP agents running on our Kubernetes cluster nodes.
During the presentation, you will have a quick demo of these components.

Granting access to a very specific resource is easy. A problem comes up when one wants to grant access to a whole database except for a particular resource (table, column, etc.). The only solution thus far is to grant access to each individual resource and omit the ones that must not be accessible. Clearly this is not maintainable, nor practical.
This is where the DENY command comes in. The gist of the feature: A user will not be able to access denied resources unless the deny is explicitly revoked. MDEV-14443 - Reverse privileges in MariaDB is an ongoing tasks that will implement it. During this talk we will go through use cases, comparison to similar features of other databases well as implementation details of the feature which will (very likely) be part of MariaDB 10.9.

GitBuilding uses your tags and meta-data to automatically generate and insert bills of materials into your documentation. It correctly links different steps to one another (even when you have multiple variants), allowing you to write instructions once and reuse them for multiple projects. It also shows previews of 3D files and lets you easily include links to generated zips and other files in the correct places. You can output the entire documentation in pure Markdown, HTML, or PDF.

The pattern is focused on run time composition. Entities are mutable sets of component data types, and systems run for entities with specific sets of components. Many ECS frameworks are oriented around components or entities, and systems use run time queries or filters to match their component data requirements against the live state.
In this talk, a system oriented ECS is presented which removes all run time work for systems by storing execution state in the systems themselves. Changing an entity's components leverages Nim's static typing and powerful AST macros to precalculate affected systems and generate pared down system state changes.
The result is statically defined and intrinsically optimised to the user's system/component design, allowing efficient embedded event loops through to complex interactive simulations.

Together with cmod, the reference pre-processor/code generator (written using C% itself), this project enables the C programmer with generic meta-programming constructs such as: parameterized verbatim code snippets, mapping code to static data tables (in TSV or JSON format), multi-pass code evaluation (allowing meta-meta-programming), compile-time command execution (allowing code generation from any other software/language), etc. as well as C-specific constructs such as: function types, named parameters, selection over strings and structs, etc. The C% standard library provides convenience constructs for inclusion in C programs.

Try mixing in the same pot: a SQL SELECT for providing the structure, Python expressions for defining transformations and conditions, the essence of awk as a data-processing language, and the JSON handling capabilities of jq.
In this event I will describe the SPyQL language, highlighting its unique features. By the end of this presentation you will know how to write SPyQL queries (probably you already know :-) ), and you will be looking forward to starting using it! I will be solving the task of calculating aggregations in awk (for a CSV), in jq (for a JSON) and in SPyQL (for both).

Asking good questions is a must have skill for software developers, especially if you are involved in open source projects. The problem with poor questions is clear when the person answering starts explaining what you already know or what you think isn't relevant. Or they might go ahead and assume that you know a lot and you end up being confused.
In this talk, Navendu walks through his experience as an open source contributor and a maintainer and how he was able to improve this skill and how it has benefitted him.

Most proprietary solutions were not suited for the task, as they were not compliant with GDPR, as they were profiling users beyond the provided service, and in many cases could not guarantee that end user data were maintained within Europe acconrding to EU legislations. Unfortunately, EU governments ignored the situation and signed contracts with big techs for remote work and remote teaching, exposing the personal information of million of EU citizens - the majority of them being students - to unauthorized practices. OSS could be the answer, but was ignored because there wasn't enough time to deploy appropriate solutions. The talk tries to provide a different perspective.

Using outdated networking software from these systems on today's Internet is a security risk (to the user and the Internet as a whole), and old software might fail altogether (old SSH clients can't connect to modern SSH server, Webbrowser can't load websites using modern transport encryption, TLS).
pkgsrc is a cross-platform package manager maintained by the NetBSD project. With pkgsrc, it is possible to compile and install modern Linux/Unix tools and applications on Unix systems that were abandoned by their makers.
In this talk, I will give my experience, tips and tricks with keeping old Unix systems up-to-date:
The option to choose a decentralized storage network in the stack of your application is far-reaching but perhaps not well understood. In this presentation, I intent to give guidance and understanding by answering the question of when it makes sense to use Swarm in your stack.I start with a brief introduction to Swarm after which I highlight 3 (not so) typical applications which already run on top of Swarm. I end by introducing the paradigm shift that we see happening when developers start to explore Swarm and truly get to know what it means for them--the avenues that Swarm opens and the new patterns that can be explored.
I hope to see you at my presentation and be sure to take all your questions to the live Q&A!

In this talk, we’ll learn what the shadow DOM is and how to use it when building reusable components. We’ll use Stencil, a web components compiler, to demonstrate the common use cases of the shadow DOM, and where it fits in the context of a design system.

As compiler engineers we experience an increase in demand for security-related features: we simply work on security-related features more often.We find it tough to analyze whether the hardenings we implement are easy or hard to circumvent by attackers. After chatting about this with many compiler developers, our experience is that most feel their work would benefit from a deeper understanding of attacks and hardening techniques. After having looked around, we didn't find much educational material that gives a broad overview, covering all aspects compiler developers ought to know about.Therefore, we recently started an open source book titled "Low Level Software Security for Compiler developers" at https://github.com/llsoftsec/llsoftsecbook/. It aims to improve the industry-wide knowledge about security hardening in compilers and related tools; ultimately leading to more innovation and better implementations of security features.In this presentation, we'll explain the rationale for this new open source project in more detail. We will discuss what content we have so far and what content we plan to add. The project very much welcomes new contributors: we need more new content, more review of content, discussion of ideas for how to make the book better, improvement in the design and layout of the produced HTML and PDF output, etc. We hope this presentation will reach both anyone interested in learning more about low-level software security and anyone interested in helping to grow this project further.

The hope is that gLean will be able to provide YahooPipes style functionality through combining blocks of references; content; annotations; and parsing-logic.
The following areas are covered:
The talk extols the virtue of the individual components (Gemini protocol's GemText; Emacs-Hyperbole's Kotl; the parser and Lisp, TXR; Jonathan McHugh's Qiuy (a 'Recursive Modelling Language')) as exemplary specialist utilities.
Examples for how Kotl format and GemText markdown can interoperate (to for instance turning a file into representative Kotl blocks; or export Kotl blocks into GemText)
The beautiful/unholy ability for TXR to read a 'raw' GemText file containing TXR syntax and for a 'compiled' GemText file to emerge (given this unintended behaviour requires no additional coding and was not designed I consider this particularly special)
The use of annotations leading blocks to provide logical structures for how a document or a collection of documents should be treated
Continuous Integration is a very important part in order to ensure a high quality software product. In order to be able to test the MariaDB server across multiple platforms, operating systems and configurations, the MariaDB Foundation has developed a continuous integration framework based on Buildbot. This talk will focus on describing the design decisions in order to be able to scale and test the MariaDB server on over 100 different configurations. We use a multi-master setup and combine Docker latent workers with LibVirt workers and classical Buildbot workers in order to achieve this.

The Raku Programming Language allows developers to specify the exact version of a module that is needed in production. This is a very good thing, and makes sysadmins all over the world pretty happy, as they know they can install new versions of modules without fear of breaking production code.
However, developers can also remove distributions from the ecosystem. This presentation describes efforts to make sure that this will never become a problem for production.

Despite being fundamental, they are rarely part of the curriculum in universities, thus undergrad and early career researchers often struggle to code data analysis pipelines and to automate data collection from experimental setups. Neurosciences, in particular, relies a lot on these skills, with behavioural experiments planning, design of the testing boxes, data visualisation and analysis. To Successfully complete these tasks, researchers need to acquire a significant level of skill in programming and hardware design.To address these problems, we are developing a flexible open hardware platform to lower the barrier in creating experimental setups: BeeHive. It consists of a main board, which nests an ESP32 microcontroller, and several dedicated “daughter boards”, each designed to perform one function (e.g. one board senses temperature, another controls motors, etc). These boards are connected to one another using a standard system already used by other Open Hardware systems, so that there is no need to reinvent the wheel. We can then focus on developing things that are not available yet. The system runs MicroPython, which is a Python derivative for microcontrollers.This architecture allows users to be in control of everything that the platform is doing while also providing plenty of room for completely new applications. Modular structure helps users to get familiar with electronic components already at entry-level expertise while Python is employed for its strong points such as simplicity and widespread usage. In this presentation we set out to explore the core concept of Beehive, describe existing and possible applications.

We have been running tests to understand the performance differences between the DPDK RCU and the user space RCU library. In our tests, we find that DPDK RCU can perform reclamation faster and perform significantly better when pre-emptive readers are involved. Other than the performance, DPDK RCU has several advantages such as not requiring a background thread for reclaiming resources and the ability to integrate with existing libraries without having to modify the application.
This talk will present various testing done on DPDK RCU and the user space RCU library and their results. It will go into the details of pre-emptive reader problem, which affects use cases beyond DPDK, and show that DPDK RCU library can reduce the reclamation time significantly.

In this talk, we will present a tool called SBOM Resolver which generates detailed SBOMs for Alpine software images. It specifically leverages meta-data from the Alpine package management system to resolve all dependencies of a list of desired packages and enhances the resulting SBOM with additional information such as patches applied by the Alpine community.
The current implementation is specific to Alpine, however, this presentation aims to introduce the key concepts and based on those start a discussion of how to apply SBOM Resolver to other distributions.

I would consider speed to be low on the order of priorities. However, it’s also one of the most limiting factors to your release cycle: if your build takes T, you cannot release faster than each T. Hence, you’ll probably want to speed up your builds after you’ve reached a certain maturity level to enable more frequent releases.
I want to detail some techniques you can leverage to make your Maven builds faster.

It has an active community that has created editors, personal projects, research projects, examples for new and advanced users, and plugins that extend the functionality of CadQuery. The project is maintained by a small core team and numerous community members. CadQuery is built on the OpenCASCADE (OCCT) CAD kernel, and has support for 2D and 3D primitives, allows 3D assemblies and 2D sketches to be created with constraints, and makes heavy use of features like selectors to help capture design intent.
There are multiple editors available for CadQuery including CQ-editor (desktop application), Jupyter-CadQuery (web based), and CadHub (web based CodeCAD sharing platform). There are repositories dedicated to examples and plugins, as well as separate projects for generating sprockets, chains, fasteners, polyhedra, and complex curves. Community members are responsible for much of the content in these repositories. There are also projects that rely on CadQuery, including in fusion research (Paramak), electrical component 3D model generation (KiCAD), and a more mouse-driven CAD application called Semblage. There are several ways of connecting with the community, including Discord, Matrix, Google Group and GitHub. Please introduce yourself and connect with other CadQuery users.

These motivate different engineering trade-offs for Kubernetes at the far edge than for cloud or near-edge scenarios.
In this lightning talk we will introduce an open source project called microshift and demonstrate how microshift can run and manage workloads on disconnected far edge devices by making frugal use of system resources. We will demonstrate managing edge deployments that can tolerate severe networking constraints, update/rollback securely, safely, speedily, and seamlessly, esp without disrupting workloads, and build on and integrate cleanly with edge-optimized OSes like Fedora IoT. Microshift can be used as a development tool, we provide a MicroShift image that bundles host dependencies like CRI-O and useful tools like the kubectl client, so it can run on most modern Linux distros, on OSX, and on Windows.

Backporting kernel patches is a complex and expensive overhead. The Linux project's position is - quite rightly - to instruct down-streams to upgrade to the latest release.
In practice, upgrading is difficult, scary and sometimes avoided. It takes time and effort before there is enough confidence that new releases will work in context: full system testing in embedded environments can be arduous. What if we could have continuous, automated full system tests, from from UI, to OS, to kernel, on hardware?
This talk will provide an overview of how this can be achieved with a combination of OpenQA, LAVA and Continuous Integration pipelines. The talk will cover:- How the same tests can be used in both kernel space and user space testing- How the same tests can run in both virtualisation (with OpenQA and QEMU, developed originally for GNOME-OS) and also on hardware- How images are then deployed and tested in hardware (LAVA triggers OpenQA via VNC to begin testing on boards)

This new library builds on what Libhandy did for GTK3 but takes it even further, streamlining many of the most common things app developers need to build great apps for GNOME, across both desktop and mobile.
This includes standardized patterns and widgets for basic layout elements like lists and cards, adaptive navigation, touch/touchpad gestures, easier ways of using color in apps, and much more.
This talk will give a quick overview of the current capabilities of the platform, and show how app developers are making use of it to build apps that work well on computers of all shapes and sizes.

Decades of experience in research and industry showed that there is no silver bullet and that different use-cases might demand different approaches to optimize safety and performance.
What if we tried to design an operating system able to be easily reconfigured into any of these points in the OS design space? What if the OS could be a microkernel, a unikernel, or a monolithic OS, at will, and using a wide range of hardware- and software-backed isolation mechanisms?
In this talk, we will present FlexOS, the result of our recent research work in trying to answer this question. FlexOS is an OS allowing users to easily specialize the safety and isolation strategy of an OS at compilation/deployment time, instead of design time. Depending on the configuration, the same FlexOS code can mimic a microkernel with multiple address-spaces, a single-address-space OS with Intel MPK compartments, or many other OS isolation approaches. We have implemented a prototype of FlexOS on top of Unikraft, a popular library OS framework.

Such a project has a lot of interesting challenges but in this talk, mostly the technical aspects will be introduced. The perspective and the journey of the editor of the book will be demonstrated, whose responsibility was to combine the chapters written by three different authors into a single, ready-to-print document.
The main tools were LibreOffice Writer and Draw but GIMP and InkScape also played a significant role.

Fueled by its radioisotope generators, after more than 40 years of flight it is still sending us data about the interstellar medium using its 3.7 metre dish antenna and 8.4 GHz transmitter. In this talk we report two adventures regarding the reception of the Voyager 1 signal.
In the first part, we show the successful detection of the Voyager 1 signal using one of the 6.1 metre dishes at the Allen Telescope Array in November 2020. Calculations show that using stable frequency references and accurate Doppler correction, this feat might also be possible for amateurs with smaller dishes if they integrate several hours of data to pull out the very weak signal from the noise. In the second part, we use some recordings done by the 100 metre Green Bank Telescope in 2015 and 2020 to decode the data transmitted by Voyager 1. The spacecraft predates the modern CCSDS standards, so its data has some interesting aspects.
All this work has been done using GNU Radio, Python, and other open source tools. The data and results are publicly available.

DESCRIPTION:The number of devices on which users cannot run Free Software is exponentially increasing. The consequence is an increased loss of control over users’ technology. In order to remediate this situation, the FSFE has been working with the concept of Device Neutrality, understood as a policy principle that ensures users equal access and non-discriminatory use of their devices. The FSFE has advocated for four main principles: stricter consent rules for pre-installed apps, no vendor lock-in, full interoperability, and real-time data portability. The talk will explain the concepts and the challenges ahead.

It offersself-healing, low latency and IPv6 connectivity without a single point offailure. In addition to the lower layer mesh functionality it alsooffers mesh network management, as well as secure onboarding of headlessdevices.
OpenThread is an open source project implementing the Thread protocol and itscomponents. The focus of this talk is to demonstrate a Linux based OpenThreadborder router and Zephyr based mesh nodes. Tight together by a Yocto basedbuild system this talk shows all components you need to have an IPv6 enabledmicro-processor on a low-power wireless link. The used power is small enoughto allow operating a small sensor for months or years on a coin cell battery in such ascenario. All served by a Linux based border router to allow for internetaccess and end-to-end IPv6 connectivity.
All of the above is bundled together in an Eclipse Oniro Project blueprintfor a transparent IoT gateway.

While eBPF has taken the cloud native community by storm, the technology has yet to make significant inroads within the embedded Linux ecosystem. I will explain the reasons for this current situation and demonstrate a possible way forward.
The bpftrace dynamic tracing language relies on the LLVM-based BCC toolchain to compile scripts down to eBPF bytecode. Because of its dependency on LLVM, BCC only supports a few 64-bit CPU architectures, severely limiting the use of eBPF in embedded systems. Fortunately, the IO Visor Project offers a lightweight alternative to bpftrace called ply. Like bpftrace, ply’s syntax is inspired by both DTrace and awk. Unlike bpftrace, ply targets embedded CPU architectures like ARM and PowerPC making it possible to deploy eBPF to many more devices. Buildroot includes ply as of its 2021.02 LTS release.

Despite the fact that a lot of types and there alignment can be defined with the “target datalayout” string, the “character” and “short” type have been hard-coded into clang and llvm.

An Edge Cluster, built on open source technologies that already exist in the Linux operating system, is a hyperconverged functional set of managed objects that include storage, network, and host resources. An Edge Cluster provides all the resources needed to run virtualized or containerized applications. OpenNebula’s management services, including scheduling, monitoring and life-cycle management, run in the cloud Front-end and orchestrate from there the local or remote Edge Clusters. The Front-end also provides access to the administration tools, user interfaces, and API. Although the requirements may vary depending on the number and size of the clusters and API load, the Front-end node only requires 8 GB of main memory and 4 cores. The Edge Cloud Architecture is able to provide a lightweight and easy-to-use storage platform for medium-sized clusters consisting of tens of nodes. OpenNebula’s Edge Cloud Architecture is able to manage hundreds of these clusters, as they operate autonomously in terms of networking and storage, and handle thousands of virtualized hosts and tens of thousands of virtualized applications. In this presentation we will explain in detail the deployment model for Edge Clusters, the specialized storage solution they incorporate (OneStor), and the performance benefits of this multi-cloud architecture as confirmed by the latest benchmarks.

Both software development and its use are essential activities for scientific teams. But investment in its production, maintenance, and adoption is often overlooked, and academia often fails to leverage best practices for software engineering from industry, the open source community, or elsewhere. Furthermore, investment in the user experience (UX) and usability of scientific software is largely an afterthought, if considered at all. As such, any future investment in UX is expected to have a disproportionately positive impact on adoption of scientific tools (i.e. broadening access) and on scientific discovery itself. Currently, the impact of this kind of investment (or lack thereof) is largely unknown.
Scientific software stands to benefit from the learnings and current practices in open source design. This talk will explore the unique workflows and incentives of research institutions (and other contexts in which scientific software is produced) and map them to current practices of open source design with the intention of bringing to light the opportunities to better understand how and when to invest in the UX of research software, how to grow expertise in UX, and how to cultivate norms on peer-production platforms toward good UX practices.

These software components, of which Crowdsec is the main piece, work by processing logs and enriching them, to apply behaviour-based scenarios (heuristics) that will identify attacks pattern. One of the core concepts of Crowdsec is to separate the detection of an attack and its reaction, to be suitable for modern architectures. While Crowdsec is in charge of the detection, the reaction is performed by "bouncers" that aim to be deployable at any level of the applicative / infrastructure stack.

These resources—along with CPU and networking— are key factors to achieve optimal performance.
In this session, we'll explore how memory allocation at the container or operating system level influences the performance of buffered disk IO, which is typically how IO is handled by PostgreSQL. We'll also examine Linux memory management details and the different ways disk IO could be performed. From there, we'll walk through a number of examples that reveal the typical dynamics of cached and non-cached IOs, as well as the differences between the two.
Understanding these dynamics is critical to learn how PostgreSQL IO works.

It was created for exascale HPC systems, where launching a computational job can involve tens of thousands of nodes and bootstrapping MPI (Message Passing Interface) becomes cumbersome. PMIx reduces launch times in such systems from minutes to a few seconds.
Even though the lower launch times are less critical in smaller clusters (but always welcome), the high efficiency of PMIx is also desirable at sub-exascale. The low data footprint and data exchange, as well as leveraging fast interconnects is useful on systems with lower-end network fabrics. Moreover, its tight integration with the resource manager is very helpful to minimize idling on clusters with limited resources.
At VUB (Vrije Universiteit Brussel), we have recently transitioned our tier-2 HPC cluster to Slurm and enabled PMIx in a mixture of TCP and InfiniBand networks. We will share the lessons learned in the process and practical tips to deploy a reliable setup with open source software.

According to the National Vulnerability Database, OSS often has security vulnerabilities. On the other hand, research has shown that developers do not update their dependencies. Because existing security tools suffer from a high false-positive rate as they analyze software at the package level.
FASTEN analyzes software packages at the finer-grain level by producing an enormous network of software ecosystems. This allows giving vulnerability information at the method level. With this information, developers are notified when their code uses vulnerable methods, and hence they are more confident to update their dependencies. The said functionality will be provided in the famous package managers such as Maven and PyPI.

Unfortunately, despite many attempts to introduce isolation to the kernel, modern systems remain monolithic. Historically, software and hardware mechanisms introduce a prohibitively high overhead for the isolation of subsystems with the tightest performance budgets. Today, however, the balance of isolation and performance is starting to change with the development of Rust, arguably, the first practical programming language that achieves safety without garbage collection.
RedLeaf is a new operating system developed from scratch in Rust with the goal to explore the impact of language safety on operating system organization, and specifically on the ability to utilize fine-grained isolation and its benefits in the kernel. In contrast to commodity systems, RedLeaf does not rely on hardware address spaces for isolation and instead uses only type and memory safety of the Rust language. Departure from costly hardware isolation mechanisms allows us to explore the design space of systems that embrace lightweight fine-grained isolation of kernel subsystems. We develop a new abstraction of a language-based isolation domain that implements a unit of information hiding and isolation of faults. Domains can be dynamically loaded and cleanly terminated. Building on RedLeaf isolation mechanisms, we demonstrate the possibility to implement end-to-end zero-copy, fault isolation, and transparent recovery of device drivers.
To evaluate the practicality of RedLeaf abstractions, we implemented a subset of the POSIX interface as a collection of RedLeaf domains. RedLeaf's isolation mechanisms allow us to support the transparent recovery of device drivers. To demonstrate that Rust and fine-grained isolation introduce a practically-acceptable overhead, we develop efficient versions of 10Gbps network and PCIe-attached solid state-disk NVMe device drivers that match the performance of carefully-optimized kernel-bypass device drivers used in modern network and storage processing frameworks.

DESCRIPTION:(With a $4 microcontroller to build fun, accessible, and unique forms of interaction)
The magic of computers and smartphones is the fact that they provide a very malleable interface - the screen. Without having to manufacture extra parts for every new application, this is a massive time and cost saving for engineers. However, this comes at a cost of accessibility and usability, as well as diminishing the physical connection one might have to the device they are using. Physical interfaces are now much easier to develop, and can even be constructed by the end user, since MCUs are now very cheap and readily available, along with lots of modular parts to construct interfaces with. Web Serial provides the added benefit of being able to use the highly distributed and easy to code with JavaScript / Web platform with these MCUs. This means rapid prototyping can be performed, along with user testing, very easily, making it much cheaper and faster to reach an end product. This talk intends to demonstrate some basic examples along with some steps to getting a process together yourself.

Lispers seem to come to like parentheses eventually and defend them, and newcomers with no preconceptions seem to not have problems as much as existing programmers do, but the fear of lisp in the general programming world remains strong. But is parenthetical notation really the best way to represent lisp? In this talk we explore several alternate representations and their practical use, and speculate on a future where everyone could benefit from lisp's unique properties without fear.

At present, there is no meta-data standard for actigraphy and light exposure data that describe aspects of the data collection, such as device manufacturer, sampling rate, or instructions given to the participant. However, meta-data like those are critical for aggregating data and comparing data collected in different samples or across various research sites. Over the past 1+ year, we have been working on developing a consensus meta-data standard for describing actigraphy and light exposure data. The standard is written in JSON-schema, and is extendable to other time-series modalities (such as temperature). The standard is the joint effort of two teams of researchers volunteering their time. In this talk, I will describe the journey from inception to standard, along with the challenges and barriers encountered.

This style of testing is admirably concise, but can lead to cryptic test messages that make it very difficult to determine what a test was attempting to check without opening up the file containing the failing test. At the other extreme, it's possible to write very expressive tests with a fluent, method-chaining API. For example, using the Chai.js assertion library, a test might read beverages.should.have.property('tea').with.lengthOf(3). This allows tests to automatically generate much more useful messages but comes at the cost of creating a fairly complex test API with many new methods to learn.
Raku's core Test module falls somewhere between these two extremes – it offers an API with a handful of functions that's easier to learn than a full fluent API but more expressive than simple assert statements. This is a sensible compromise.
But I claim (assert?) that, with a bit of metaprogramming trickery, Raku lets us have the best of both worlds: we can have a zero-learning-curve test API that's just as simple as assert statements while also being just as expressive as a long chain of method calls in a fluent style. I'll present this style of testing, discuss its use in Raku, and consider ways in which Raku lets us improve on the status quo.

The quantification of light, particularly in parameters relevant for humans, is subject to international consensus documents developed by the International Commission on Illumination (abbreviated as CIE = Commission Internationale de l’Eclairage). This includes quantities for the intensity of light exposure (e.g., illuminance, measured in lux) or indices of how well a light source renders colours (e.g., Rf). The CIE provides various spreadsheet-based tools for calculating these quantities from spectral measurements of radiant energy. Here, we present and discuss the open-source and open-access web platform luox, which was developed with researchers in mind to simplify the process of calculating relevant aspects of light exposures in experiments with human participants. We specifically focus on the challenges of translating written documents and equations into a web based platform using ES6 and ReactJS.

Data repositories are improving in their ability to store this data, but there is a growing need for interoperability between disparate data sources and applications. The Breeding Application Programming Interface (BrAPI) project offers a solution to this problem with a standardized RESTful web service API specification. This specification provides a standard data model for the plant breeding domain, plus a well-defined set of methods for interacting with the data. The goal of the project is to promote interoperability, data sharing, and open source code sharing across organizations who produce and consume data in this domain. The BrAPI project is a community built project and that community is well established and continuously growing. The standard is built based on concrete use cases to solve real interoperability challenges faced by the community. Beyond the core standard, the community has built a variety of open source tools and resources to help build and test implementations of the specification. The community is also constantly producing new BrAPI compliant applications, analysis tools, and visualizations that will work with any BrAPI data source.

Originally developed for Postgresql Europe's own conferences, the system has grown into a generic system for managing events, visitors, speakers, sponsors, and volunteers. It integrates the functions such as call-for-papers, managing schedules, invoicing, accounting, and more.
In this talk we will do a whirlwind tour of the tool, from the context of the foss-north conference.

However, the programming models for heterogeneous hardware accelerators inherently support C/C++, thereby hindering the exploitation of heterogeneous resources from managed languages, such as Java. In the University of Manchester, we have been developing TornadoVM; an open-source software technology that can be used as a plugin to OpenJDK and other JVM distributions to enable hardware acceleration in a programmer friendly manner.
In this talk, we will present a practical view of TornadoVM and focus on two parts: (i) analyze what can impact the performance of applications on heterogeneous co-processors, and (ii) how Java developers can utilize TornadoVM to increase the performance of their applications.

While these technologies virtualise different layers of software and hardware, they have one common thing: they are quite inefficient in terms of communication between isolated entities. The isolation relies on MMU and involves a privileged intermediary, which leads to heavy transitions or sharing data at the page granularity. The escape from this trap we see in the hardware capabilities introduced in CHERI. The CHERI architecture efficiently combines hardware memory capabilities with conventional MMU architectures. It gives not only safety to memory pointers, but also provides lightweight isolation mechanisms.
In this talk, I will present Introvisor, a lightweight hypervisor for microservices. It uses CHERI capabilities for isolation and data sharing, does not require software porting thus compatible with existing software, and provides strong security guarantees.

In this presentation, we'll take a look at a radically different approach to building web apps in Java.
Vaadin Flow is a unique web framework that lets you build apps in plain Java using an extensive library of included UI components. The resulting app is a highly-interactive single-page app based on the latest web technologies.
You'll learn the basics of building apps using this open-source framework and be ready to start turning your idea into an app.

If they are not water resistant, they offer an internal µSD card slot containing the whole operating system and bootloader so that sounds like an invitation to do something interesting with them besides just reading books. Especially in prolonged outdoor activities, the display and their low power consumption have their merits. Hardware is quite similar, so you also have chances to get a replacement next corner.Several devicetrees and also some drivers made their way into mainline linux now, on others upstreaming work is in progress. Support is starting to find its way into mobile linux distributions like postmarketOS and graphics start to work with standard APIs.In this talk I talk about my experiences, especially the current state of support in mainline linux, what is missing and what are the challenges. I will also talk about requirements for the graphics userspace and shortly present my favorite use case: displaying maps.

The dependency on the network continues to grow as more and more microservices depend on it. However, there is no way to predictably leverage the network for the specific demands of your application. What if we could tag certain applications as needing a priority from the network. This would enhance the networking capabilities offered from Kubernetes and compliment the deployment of applications that require predictable behavior of the network.

The result is that it is still complicated to create fast and responsive virtual machines locally.
Phyllome OS is a Fedora Remix based on Fedora Server which attempts to make it easier to run virtual machines locally on computers that support hardware-assisted virtualization, using mostly paravirtualization (aka virtio-devices). It currently relies on existing technologies (libvirt; KVM/QEMU; virt-manager; GNOME Shell; etc), but will eventually implement its own virtual machine manager, package the cloud hypervisor as an alternative to QEMU, and use filesystem-level encryption to protect virtual machines disks. The main idea behind this OS is to treat the host, Phyllome OS, as a read-only system, i.e. as a mere appliance to host virtual machines. The presentation will give a demonstration of Phyllome OS in its current state.

AOSC OS/Retro, as an official branch of AOSC OS (the modern-device-facing mainline), runs a generally similar feature set - systemd, Glibc/Binutils/GCC/Coreutils/Util-Linux, X.org/Mesa, etc. and shares the same source tree with the latter.
With over a year of spending our spare time on the project, tweaking features, designing a desktop experience, and optimising compiler flags, we have a usable distribution that could run on systems as slow as a 486SX, and as fast as "modern" Core Duo systems. We also have an active effort to port AOSC OS/Retro across multiple architectures, with the tally currently standing at eight architectures - and counting (alpha, armv4, armv6hf, armv7hf, i486, loongson2f, powerpc, ppc64). We still have a long list of issues to solve, such as login delays and throttled I/O on ISA-based systems. I hope to gather feedback and criticism through this presentation.

The data acquired from photo-detection module, received after a sweep of laser source, needs to undergo sophisticated post processing to obtain the final results. The system must monitor position of a large number of elements every second. Dealing with 1000s of target points in less than 1 second required time-optimized and precise calculation. Thus, GPU was employed to provide faster and precise results. This required to use signal processing algorithms like: Butterworth Filter, Hilbert Transform, Savitzky-Golay smoothing Filter in GPU.This talk will cover steps involved in adopting signal processing algorithm to GPU to achieve better performance and understand the effects of parallelism achieved. For the initial development, CuPy library for NVIDIA GPUs is used and later moved to implementation in C. CuPy provides wrapper for most of the CUDA toolkit in Python. We will also provide highlight about performance metrics with respect to increase in the data size and possible optimizations of its processing.

We will step through the new features and what they enable before going further in depth with some examples of the upstreamed Hardware Accelerator Support that was presented last year at FOSDEM. This feature provides streamlined data movement via support of "custom buffers" which allow a device-compatible mapping of the memory presented to a block's work function, eliminating additional ingress/egress in and out of device memory. We will show how this impacts specifically flowgraphs that have CUDA enabled blocks as a concrete example.

It is a proxy between MongoDB clients/driver and PostgreSQL, developed in Go. Since the very first commit, it used a version of Go which soon will be released as Go 1.18. The two biggest reasons for that were first-class support for type parameters (generics) and fuzzing. In my talk, I will cover both of them: how they work in theory and our practice, how they were useful for us (spoiler: very useful), and what are their downsides and gotchas.

As such, extracting information from the machine can prove difficult. Moreover, because Unikraft offers support for running a single process at a time, alternate solutions had to be found for exporting data. Prometheus is a common tool used to collect and visualize data that offers decoupling from the observed system, as such, we saw it as a prime candidate for exporting information.
Our solution was to port a Prometheus exporter inside Unikraft as a separate library and run it on a separate thread. Information from the unikernel is extracted by Prometheus through an intermediary library, named ukstore, that behaves like a simplified ProcFS. ukstore offers an easy method for accessing information and metrics from the system. Using Prometheus with Unikraft, we are thus able to extract performance metrics from highly-specialized virtual machines, store them in a time series database and display them using plots.

It will demonstrate how games and other software can define their entire logic as a series of independent rules, and how it decouples your data much like (but more powerful than) an entity component system.

Services and policies are implemented at user-level, the kernel focuses on fast IPC, and it uses a strong capability-based access control mechanism. It has historically focused on being a research laboratory for strange features including a thread-migration-based IPC, user-level scheduling of system-level threads, user-level definition of capability policies, a wait-free kernel that scales linearly with increasing cores, and temporal capabilities to coordinate between untrusting schedulers. It also scales down and supports paravirtualized RTOSes on microcontrollers (with on the order of 64KiB SRAM, between 16 and 200 Mhz, and MPUs). Composite represents a design that deviates from the L4 lineage in some interesting ways. In this talk, we'll discuss the design with a focus on how the system provides the challenging combination of predictability, performance, and scalable parallelism.

Following the pioneering work of the Gene Ontology at the turn of the century, the Open Biomedical and Biological Ontologies (OBO) Foundry was created to coordinate the development of a family of interoperable ontologies sharing a core set of principles. The Foundry now includes more than 150 ontologies.The Ontology Development Kit (ODK) [1] was developed to facilitate the implementation of standardized ontology development practices across the Foundry. It takes the form of a Docker image that provides ontology editors with all the command-line tools they need to manage, edit, build, and test their ontologies, as well as standardized and carefully crafted Makefile rules to pilot all steps of the ontology life cycle. In recent years, many ontologies such as the Uberon multi-species anatomy ontology, the Cell Ontology (CL), or the Unified Phenotype Ontology (uPheno) have been converted to use the ODK. By moving most of the management, building, and testing logic from the individual ontologies to the ODK, the kit aims to make the life of ontology editors easier, by allowing them to focus solely on actual ontology editing, all the while contributing to the standardisation of the various ontologies.

State management is a controversial topic among all developers, and it's, at the same time, one of the most complex topics that developers should decide on when they are building a Flutter app. Many developers say one solution is the best, whereas some disagree! What if I tell you that, in my opinion, there is no right and wrong answer! If you ask a software architect, which state management is the best for an application? The answer is evident; It Depends.This talk discusses how to think like an architect and understand, recognize, and analyze tradeoffs and characteristics when choosing state management. I will show you why all state management might be best and worst, at the same time for your application which eventually helps you to make your mind to determine your appropriate solution.

CPU management may seem complex, but it can be explained in such a way that even your inner toddler will comprehend. With this talk, we will give a path to success.
You may have a multi-socket node cluster where your AI/ML workloads care about the proximity of your CPUs to GPUs. You may be running scientific workloads where you want to pin in cores within containers instead of just a pod level. You may have a single-socket server where you want to save a single core outside of Kubernetes for a daemon dedicated to mining bitcoin, without affecting your other jobs (please do not do this). We will cover these and more, helping you understand the intricacies of CPU management within the kubelet and what Kuberenetes can and cannot currently do. We will also cover how you can help escalate the visibility of use cases not currently covered within Kubernetes.

However, the reality of high concurrency usage is often disappointing, with less throughput than one would expect. Because of its internals and its multi-process architecture, PostgreSQL is very particular about how it likes to deal with high concurrency and in some cases it can slow down to the point where it looks like it's not performing as it should. In this talk we'll take a look at potential pitfalls when you throw a lot of work at your database. Specifically, very high concurrency and resource contention can cause problems with lock waits in Postgres. Very high transaction rates can also cause problems of a different nature. Finally, we will be looking at ways to mitigate these by examining our queries and connection parameters, leveraging connection pooling and replication, or adapting the workload.

In the servers’ domain, resource utilization is nowhere near as relevant as it is in the embedded domain. The different languages and technologies that power the tools and mechanisms through which containers are leveraged in the bare metal server and /cloud worlds just don’t fit into the requirements of embedded.

With a p2p backend, an application can easily move between connecting people over the internet, to local and ad-hoc networks, and working entirely offline. We take this ability a step further by integrating several protocols into web browsers so that applications can be authored and distributed just like any other data in the network.
This talk will go over some of these protocols, their strengths and weaknesses, and how we have applied them to the web. We'll also have a live demo of what it looks like as a developer.

This lowers battery usage, improves latency and leaves the 3D engine free for clients to use. The display engines found in modern GPUs often can support this zero-copy mechanism only if the buffers have been allocated in a special fashion. However, buffers allocated this way won't be optimal for rendering, and only a handful of buffers can be directly displayed.
As a result, a trade-off between zero-copy display and optimal rendering needs to be made. The compositor is the natural place where a decision can be made, because it has a global view of all apps which need to be presented. Once the compositor has taken a decision, it needs to be communicated to the clients. The brand new linux-dmabuf feedback protocol enables this negotiation between the compositor and the clients.

The sensitive nature of these tools makes them difficult to use in a testing environment. On the one hand, exposing access to production keys in your CI is obviously a terrible idea. But on the other hand, setting up and maintaining a fully functional "mock" PKI environment is also pretty tricky. What can you do about that?

This presentation will cover various techniques tried by the Webrecorder project to keep Flash content still working in today's browsers, such as running old browsers in containers, running full system emulation in WebAssembly, and using the Ruffle emulator. We will cover the trade-offs between these approaches and the current challenges in combining web archives and emulation, and present the tools we have built to make these approaches possible.
As one of the options, will also talk about the OldWeb.today project (https://oldweb.today/) which provides several JS-based emulation connected to web archives, how it works and how it can be used to run not only Flash, but also old Java applets that may exist in web archives.

However, current software localization in modern JS frameworks and other software is complicated and fairly time-consuming for all involved participants. Thanks to the in-context localization feature of open-source project Tolgee, this tool offers easier localization process, more relevant translations delivery and finally less work for developers.
The workshop will contain live demo where I would like to describe using Tolgee JavaScript software development kits on simple React.js web application example. However, Tolgee is currently compatible with other frameworks such as Angular, Svelte, Vue.js or Next.js.
Participants will learn easy localization workflow using by Tolgee tool, simple localization texts management, how to integrate Tolgee into web app in less than one minute, how to take advantage of different Tolgee features as e.g. automatic generation of screenshots or in-context localization.

First, the rise of big data analytics, high performance computing, machine learning workloads that need high-bandwidth and low latency and sometimes even requires access to special hardware devices like GPUs or DPUs. And at the same time, in the telecommunication space, the 5G networks technology stacks that drive the need for IPv6, SR-IOV, Container Network Functions (CNFs), NUMA topologies, and other innovations in containerized applications on bare metal.
All of these emphasize the need for the ability to easily create Bare Metal based OpenShift clusters as automatically as possible.
Central Infrastructure Management (CIM) exposes an intuitive user interface, allowing the infrastructure administrator to define a pool of Bare Metal machines making them available for users to independently create OpenShift clusters from them.
Assisted Installer is an operator that introduces a new way to deploy a new OpenShift cluster on bare metal basically by only booting the nodes that will be part of the cluster, with an ISO it generates. The Assisted Installer will report inventory, run validations and orchestrate the needed steps based on the user parameters.
CIM and Assisted Installer are components of Open Cluster Management (OCM), an operator that enables a single OCP cluster to manage a fleet of clusters.
In this session, you will learn about Central Infrastructure Management and Assisted Installer architecture and its components. We will discuss the installation flow and how the components interact with each other. Finally, we will demonstrate how to build a pool of Bare Metal and install an OpenShift cluster on them via the CIM user interface.

It aims to facilitate collaboration across various institutional and individual partners in order to ensure the continued development and long-term sustainability of Wikibase, a suite of tools for data management within a linked open data environment. Wikibase is currently developed and maintained by Wikimedia Germany, a chapter of the non-profit Wikimedia Foundation. Wikibase is vital infrastructure for the public linked data project Wikidata, but since its open release in 2015 it has been increasingly taken up in research, cultural and institutional contexts due to its flexible, open and collaborative architecture. Rhizome have been piloting the use of Wikibase within GLAM contexts since its release, and have co-organized the first set of public meetups and events around the emerging Wikibase community and ecosystem of decentralized Wikibase instances. Following the success in bringing the community together through these events Rhizome and a few early adopters started the Wikibase Stakeholder Group at the end of 2020. In this talk, we will present the activities of the Group to date, lessons learned from our experiences in collective decision-making, funding for collaborative development efforts, and negotiating between individual project requirements towards a common roadmap in line with ongoing efforts of the Wikimedia team.

We are able to saturate a PCIe link (7 Gbps) in loopback mode. IQ samples are streamed from the RF IC at more than 350 Mbps. Implementation of this architecture required the development of a new LiteX-based Artix FPGA gateware, and a new SDR framework written in the Julia programming language. The combination of extremely high throughput, GPU computing power, and efficient Julia code will open the doors to a new generation of phased-array and machine-learning experimentation.

After getting a bunch of real world maintenance experience managing the POWER architecture support in Void Linux, I have decided to make those ideas a reality - a distribution with the Linux kernel, but FreeBSD userland, LLVM/Clang system toolchain and core runtime, musl libc and a fair amount of custom tooling. Right now, it is a bootable system targeting a variety of CPU architectures (aarch64, ppc64le, riscv64, x86_64...) that is easily bootstrappable (and capable of building itself), testable, lightweight and fast (but still in heavy development). It uses the apk package manager (of Alpine Linux) and a completely custom source packages collection and build system written in Python, allowing for sandboxed, fully unprivileged package builds.

DESCRIPTION:Recognizing community members is one of the most enjoyable activities for community managers. It is a great opportunity to thank people for their work and highlight their contributions to the rest of the community. However, we need to evaluate if we’re truly being inclusive with our community recognitions. For example, when discussing contributors, we still see a lot of emphasis on the volume of contributions on project repositories (i.e., code) that some may find intimidating. This focus on code is partly because contributions on tools like GitHub and GitLab are easier to measure and quantify.
On the other hand, it can be more challenging to measure (or even notice) how much a community member is helping others on platforms like Discord, Matrix, Slack, etc. When someone helps a newcomer by answering a quick question in chat, it’s easy to miss that among other discussion threads. Even though it can be more challenging to quantify non-code contributions, it’s crucial to look beyond repositories to see how people are helping to improve our communities. In addition to contributions in chat-like platforms, this can include sharing their use cases, participating in meetups, providing honest feedback in 1-on-1 conversations, etc. Looking across a broad spectrum of contributions will help ensure that we recognize everyone regardless of their background, interests, and skillset.

This has led to the creation of many public test suites — test suites independent of any particular emulator, which can usually even run on real hardware. But these suites tend to assume a lot of working functionality beyond the part they are specifically testing, being designed by an intelligent human being to test complete emulators holistically.
This presentation covers an alternative source and target of emulator tests: random numbers, to test individual processor instructions, so that future emulator authors can test from day one.

DESCRIPTION:Of the three observability data types supported by OpenTelemetry (metrics, logs, and traces) the latter is the one with most potential. Tracing gives users insights into how requests are processed by microservices in a modern, cloud-native architecture.
Jaeger and Grafana can visualize a single trace, showing how an individual request traversed your entire system. This helps for distributed debugging and analysis, but using traces only this way is limiting.
What if you stored tracing data in a SQL database? You could ask global questions about your system. You could find slow communication paths, where the error rate spiked since the last deployment, or where the request rate suddenly dropped. Thus, tracing can be used proactively to help you spot issues before your customers do.
This talk will show you how to do all the above by ingesting OpenTelemetry traces into a PostgreSQL/TimescaleDB database, and building custom dashboards using SQL to make the most out of your tracing data.

When such a package adheres to semantic versioning, backports can be recognised as new releases in a lower major train. This is particularly useful in case a substantial number of software packages continues to depend on that lower major train. In this talk, we discuss the backporting practices in four popular package distributions, namely Cargo, npm, Packagist and RubyGems. We observe that many dependent packages could benefit from backports provided by their dependencies. In particular, we find that a majority of security vulnerabilities affect more than one major train but are only fixed in the highest one, letting thousands of dependent packages exposed to the vulnerability. Despite that, we find that backporting updates is quite infrequent, and mostly practised by long-lived and more active packages for a variety of reasons.

The GNAT compiler implements this support in its runtime library, which comes in a number of different flavors, with more or less capability. The GNAT light runtime library is a version of the runtime library targeted at embedded platforms and certification, with an Operating System or without it (baremetal). It contains around 180 units focused mostly on I/O, numerics, text manipulation, memory operations.
Variants of the GNAT light runtime library have been certified for use at the highest levels of criticality in several industrial domains: avionics (DO-178), space (ECSS-E-ST40C), railway (EN 50128), automotive (ISO-26262). Details vary across certification regimes, but the common approach to certification used today is based on written requirements traced to corresponding tests, supported by test coverage analysis. Despite this strict certification process, some bugs were found in the past in the code. An ongoing project at AdaCore is applying formal proof with SPARK to the light runtime units, in order to prove their correctness: that the code is free of runtime errors, and that it satisfies its functional specifications.
So far, 30 units (out of 180) have been proved, and a few bugs fixed along the way (including a security vulnerability). In this talk, I will describe the approach followed, what was achieved, and what we expect to achieve.

However, shell scripts are notorious for being "duct tape", and are hard to adapt to different hardware and software environments. Workflow languages such as the Common Workflow Language (CWL) were developed to address this pain point. However, CWL does come at the cost of increased verbosity and reduced readability. Even seasoned scientists shy away from writing CWL, and fall back to the familiarity of shell scripts.
This need not be. There is no reason to inflict the behind-the-scenes complexity of workflow languages on the user. It should be possible to automatically translate (in other words, compile) a simple shell-like script into a workflow language specification. In effect, we create a new domain specific language that is almost as easy to write as a shell script, but compiles to CWL. No other language is better suited to this task of creating domain specific languages than lisp. The lisps with their homoiconicity and unique macro system empower the programmer to use ordinary code to hack the compiler itself.
In this talk, I will present the Concise Common Workflow Language (ccwl). The Concise Common Workflow Language (ccwl) is a concise syntax to express CWL workflows. It is a compiler that compiles a simple lispy shell-like workflow specification into a CWL workflow. It is implemented in the Scheme programming language, a minimalist dialect of lisp. I will discuss the considerations that went into the design of ccwl, and demonstrate its expressive power with illustrative examples.

PC/IX was the first one that IBM supported, but VentureCom created released this port about the time PC/IX was announced. They ported it to a number of the 'near compatible' systems as well, so for many people the first Unix available on those early 8086/8088 machines was Venix. This included the DEC Rainbow 100B with Venix/86R.
A companion project to recreate the sources for Venix/86 from 7th edition tapes now available was hampered by the slow speed of the DEC Rainbow, so I wrote the emulator to seed that along.
This talk will be about the emulator's structure, system call interface and portability to other ancient 8088/8086 Unixes. It will also discuss how many of the early ports coped with lack of a MMU in clever ways. It will touch on the path here, and then focus on the current implementation.

More recent platforms (AMD SEV, Intel TDX, AWS Nitro Enclaves) operate at the VM level. This provides significant new capabilities for multi-process abstractions such as mmap and fork, which will be beneficial for enclavizing legacy software.
However, taking a VM image and running it in an enclave is not great from a TCB minimization standpoint. For platforms where there's currently no alternative (AMD, AWS), how can we build--with a minimal TCB--an abstraction that's similar to single-process enclaves? Of course you can “just run Linux” with a single process but this again is clearly suboptimal. We'll explore the solution space in this interactive session.

Nowadays, models with up to billions of parameters are trained for vast arrays of downstream tasks and obtain performance that defies what a lot considered possible 20 years ago. However, the reliance of machine learning models on the spurious correlations often prevents them from learning the intrinsic and invariant features of data, leading to their failure to generalize to Out-Of-Distribution (OOD) data. Understanding and overcoming these failures have led to a research program on OOD generalization.
The field has been extensively explored in the static computer vision tasks (Domainbed, WILDS) but has been severely underexplored for time series tasks essential for multiple areas of applied machine learning, e.g., medical, finance, communication. We propose a set of new open source out-of-distribution generalization datasets for sequential prediction tasks spanning multiple modalities that act as benchmarks for potential algorithms that promote invariant learning. Along with the datasets, we provide a fair and systematic open-source platform for evaluating the performance of existing and potential algorithms on these datasets. We also provide a leaderboard that currently consists of popular algorithms' performance in the field of OOD generalization.

In this talk, we will cover in detail a unique way of integrating a robust and secure over-the-air software (OTA) updates with the NVIDIA JetPack 4.6 production release that works for all Jetson System-on-Modules (SoMs) with support for the official L4T (Ubuntu-based) operating system, running JetPack 4.6 or later. As it is built on top of the latest JetPack SDK release, there is no need to have separate integrations when building and deploying applications on different Jetson SoMs. This has the benefit of enormously cutting down the bringup time of an OTA solution to do all types of OTA updates. It has low maintenance costs since it does not involve modifying the boot process and rather relying on officially supported tools by NVIDIA which should not “break” with new L4T releases or board changes. We will cover the details of the integration with the high-level user flow as outline below, which “clones” the running image of a golden device and deploys it in a robust manner to the entire fleet of devices:

But is it really that fast (spoiler: yes, but not when used with python)? In this talk, I will be covering a real-world example in the domain of genetics, and demonstrating how I was able to out-perform numpy code running on my intel-7700k machine with a raspberry pi running code from the Nim programming language!
I will also be providing optimization tips for speeding up your code, with a focus on comparing python with the Nim programming language.
The talk can be roughly divided into the following sections:
Part 1 (32 min) - Introduction to myself. Describing a computationally expensive problem that I have experienced when working with Python.- My background is in data science and biology- Biologists tend to work with large datasets- One common problem we face is preprocessing of large amounts of data. A common technique used here using distance calculations- Why I decided to learn a different languagePart 2 (1 min) - High level introduction to Nim- Nim is a statically compiled programming language- Etc...Part 3 (10 min) - Going through step-by-step on how to write performance optimal code with Nim. Describing common performance pitfalls that Python users may not be aware of.- Inlining- Using the type system to your advantage- Taking advantage of domain knowledge- Multi-threading (openmp)- Bounds checking- Compiler flags- Mathematical and algorithmic optimizationsPart 4 (3 min) - Benchmarks and closing statement- Show benchmark comparing the naive python numpy implementation with the highly optimized Nim one- Top tips to keep in mind when writing high performance code.
Please note: the purpose of this talk isn't to be an exploration of some new state-of-the-art way of doing performance optimization or some relatively unknown optimization techniques. This is a general introduction for people hoping to use Nim for HPC that are coming from Python. Lots of emphasis will be put comparing the two languages.

LibreOffice consistency represents a strong advantage over the "siloed" approach of all other office suites, where there is a different software engine for each application and each platform. The result is a lack of consistency for files, which are also different by platform. LibreOffice Technology is the best open source platform for personal productivity, and is tightly integrated on desktop, mobile and cloud.

While Kubernetes allows for other paradigms on top of it which allows pods to coordinate on individual jobs, setting them up and making them play nice with ML platforms is not straightforward. Using Apache Spark and Apache Mahout we can work with matrices of any dimension and distribute them across an unbounded number of pods/nodes, and we can use Kubeflow to make our work quickly and easily reproducible. In this talk, we’ll discuss how we used Apache Spark and Mahout to denoise DICOM images of lungs of COVID patients and published our Pipeline with Kubeflow to make the process easily repeatable which could help doctors in more resource limited hospitals, as well as other researchers seeking to automate the detection of COVID.

By using the Readability library, along with some haphazard PHP, I was able to take modern sites down to text content and HTML 1.1 on the server side. FrogFind.com serves as a web portal for limited browsers, such as old versions of Mosiac, or even text browsers like Contiki's on an Apple ][, to make much of the web's content accessible to them in a perfectly readable way.

Those allow teams to develop a feature throughout multiple releases without users being aware that this feature is under development. Shorter release cycle are still possible without hindering quality teams or users.
At GitGuardian, we use feature flags for multiple purposes: distinguishing between code deployment and feature rollout, managing differences for premium accounts and A/B testing. We will talk about how we handle feature flags for saas and on premise deployment and how to avoid some common on premise pitfalls with feature flags.

The Flux Ecosystem is a suite of decentralized computing services and blockchain-as-a-service solutions together to offer an interoperable, decentralized AWS-like developmentenvironment. Flux utilizes a native POW coin to power this ecosystem, providing incentive for hardware hosters, governance on-chain, and bad actor mitigation via stakingrequirements for running hardware. The Flux operating system runs on top of Linux to provide the network with verified, enterprise-grade compute power and utilizes theblockchain to ensure transparency in governance operations. This allows almost anyone to be rewarded for providing hardware to the network, from anywhere in the world.

DESCRIPTION:Keeping the size of of your containers small is more important than ever, especially when distributing container images for others to build upon them. However, once multiple container layers get involved, even the data collection aspect becomes challenging and most existing tools do not primarily focus on visualization.
We will present a simple tool that we created for this: it is a simple web app that produces sunburst graphs for each layer of a container image and can thereby aid you in finding out where the size bloat comes from. Go and grab it from https://github.com/dcermak/container-layer-sizes and give it a spin yourself!

Instead of building an end-to-end solution for MLOps, Crane focuses on one piece of the puzzle and provides a friendly solution to a problem we encountered daily. Building a container, dealing with registries, and keeping track of what you’ve already built, are tedious tasks, but they’re things you need to do often. Let’s build a tool for it and save time for data scientists, then they can focus on the real problems to solve.
When it comes to building a container image, there are lots of gaps to fill. In this talk, we’re going to share why we build Crane, how could it help data scientists, why we choose to build Crane with the community, and what’s the possibilities Crane has to boost productivity for data scientists.

In order to simplify application development, service mesh architectures have emerged as the evolutionary architectural paradigms for taking care of bulk of application communication logic such as health checks, circuit breaking, secure communication, resiliency (among others), thereby decoupling application logic with communication infrastructure. The latency to throughput ratio needs to be measurable for high performant deployments at the Edge. Providing benchmark data for various edge deployments with Bare Metal and virtual machine-based scenarios, this paper digs into architectural complexities of deploying service mesh at edge environment, performance impact across north-south and east-west communications in and out of a service mesh leveraging popular open-source service mesh Istio/Envoy using a simple on-prem Kubernetes cluster. The performance results shared indicate performance impact of Kubernetes network stack with Envoy data plane. Microarchitecture analyses indicate bottlenecks in Linux based stacks from a CPU micro-architecture perspective and quantify the high impact of Linux’s Iptables rule matching at scale. We conclude with the challenges in multiple areas of profiling and benchmarking requirement and a call to action for deploying a service mesh, in latency sensitive environments at Edge.

Do you wonder how to automate chaos tests into your delivery pipeline to validate your services can deal with failing nodes? When we at Dynatrace started our microservice journey, we had to deal with precisely those and many more questions. Using Keptn as a control plane for application delivery, we can orchestrate all those tasks to avoid any bad deployments while providing a unified deployment experience for our developers. In this talk, I will bring some light into combined infrastructure and application deployment using Keptn to show you how those seemingly separated activities can be unified.

Every Linux distribution has got mostly separate maintainers and hardware distributors are handling these communities really often disconnected. That has been identified also for the architecture s390x. Therefore, openSUSE, Fedora and Debian have established together with IBM a Linux Distributions Working Group for a better collaboration together and with the goal to receive better support. In this presentation you should receive an overview about a good collaboration between Linux distributions and what you can achieve together with such a Working Group.

Using the latest features in sudo lets you watch some functions that previously were blind spots and you can also control access to them. There were several minor and major changes since the 1.9.0 release that I discussed in my previous FOSDEM talks. Here are the four major new features allowing you see your blind spots:
instead of giving full shell access, you can fine-tune the working directory and chroot settings
JSON-formatted logs give you more details on events and are easier to act on
relays in sudo_logsrvd make session recording collection more secure and reliable
you can log and control sub-commands executed by the command that is run through sudo
Have you ever wondered why spreadsheets look and act that way? Why does LibreOffice and Excel use letters for columns and numbers for rows? In this high energy presentation, Jim Hall will discuss a brief history of spreadsheets, from LANPAR to VisiCalc to Lotus 1-2-3 to LibreOffice. A great history lesson and practical demonstration.

But why would you use it? How is it used in the real world? We will explore the "power levels": starting from generics, continuing to templates and finally arriving at macros.
We will first look at generics usage in VMath (Vector Math Library) and Jsony (JSON Parsing Library). Then we will continue on to templates and how they are used in VMath and Windy. Finally we will look macros, the top of the "power levels", and how they are used in Shady (a Nim to GLSL compiler) and Genny (Generates bindings for Nim libraries).

CubicWeb is a SCMS (Semantic Content Management System) for Linked Open Data (https://forge.extranet.logilab.fr/cubicweb/cubicweb).This python-based framework can be used to import OWL schema and RDF data automatically to generate a new CubicWeb instance.This instance can be used out-of-the-box as a single application to serve RDF data through a conventional web interface for browsing and throughcontent negotiation for downloading. No need to configure anything, just import and launch the app.The CubicWeb framework implements an administration interface to manage data easily evenfor non-technical people.

It’s easy for aspiring talents to feel lost, be ashamed and give up in the process due to the transparent aspect of work in open source. We believe we found a quite neat shortcut to this!
The solution is called “structured mentoring” and in this talk, Prem and Bartek, maintainers of CNCF projects, will explain why this is a game-changer, based on their experience mentoring 20+ talents for the Thanos and Prometheus projects.
There are many mentoring programs like LFX, GSoC or Outreachy but it is easy to make mistakes, get lost and have no results from mentoring if not done carefully.
Join us to learn what processes worked the best to get the most out of the open-source mentorship. Learn what mistakes to avoid, how to get mentored and how to start mentoring in your company or open source project today

Environmental conditions influence agricultural activity; in particular, climatic conditions have a favorable or detrimental effect on production. Thus, it is essential to monitor and analyze the different agro-meteorological variables to describe these conditions and their impact on agricultural and livestock production. With this approach, INTA has an extensive ground network of conventional and automatic weather stations. In addition, there is an information system (http://siga.inta.gob.ar) with predefined queries and visualization on this data for internal and external use. All the information generated by the institution is openly shared under a CC-BY-NC license.INTA is a decentralized institution and generates research, analysis, and reports at different scales (national to local). The processes to perform these tasks use various software tools and different methodologies. Moreover, these processes are in the computer and the head of the researchers.
Developing internal packages or libraries has great potential to promote reproducible analysis frameworks, improve an organization's code quality, enhance knowledge management (Riederer, 2021), standardize and make processes transparent, and open software and data to society.
The {agromet} package includes a series of functions that can be used regularly for the calculation of agrometeorological indices and statistics. The input meteorological data works under the tidy data philosophy, so the package functions are generic. They can be applied to any tabular dataset regardless of its origin, order, or column names. However, according to INTA's internal requirements, the package also incorporates tools to read data in an INTA format. This package has implemented functions for calculating indexes and variables of agricultural interest, standardizing how these computations are made. It also incorporates mapping functions with scale and reports templates.
The package {siga} downloads and reads data from INTA's Agrometeorological Information and Management System programmatically.
This talk will discuss the decision process to generate a series of internal packages designed to be used by INTA users but with enough generality to be helpful to a broad community. Their development, current use, and this experience encouraged the generation of similar packages for soil data.

This also includes basics such as filesystem support.I took on the challenge to implement NTFS, the primary filesystem used by Windows, in a Rust crate that is equally usable from the firmware level up to user-mode.
While Rust has been conquering the system software landscape for the past few years, there are next to no examples for implementing filesystems.Likewise, NTFS only has a single major open-source implementation known as ntfs-3g, and it was developed in C over a decade ago.
This talk will cover my motivation for targeting NTFS and various use cases for such a Rust crate. I will introduce you to the internals of the NTFS filesystem, how they influenced the crate's design, and how Rust's features can be leveraged to create a safe and maintainable implementation. My talk will cover the current implementation, but also the necessary iterations until I got there.Finally, we will also deal with the current limitations of the Rust ecosystem and possible future improvements to the crate.
You will see that Rust has many advantages for implementing filesystems, and I hope to see more such crates in the future.

With the knowledge-base we pursue the goal to make sustainable software development possible for everybody. Most importantly, we want to encourage people without strong computer science background to apply fundamental best practices, e.g., version control, from the start. We believe this is necessary since many engineers – and not computer scientists – write scientific code. Starting from version control, the topics range to fully automated experiments using CI/CD workflows. Many of the existing examples concern OpenFOAM development due to the knowledge-base’s heritage in TU Darmstadt’s CRC 1194. Since then, we also are working with the Lehrstuhl für Hydromechanik und Hydrosystemmodellierung (LH²) as well as with the Institute of Wasserbau and the Institute of Fluidsystemtechnik at TU Darmstadt.
While curating the content, which we maintain in a Gitlab repository using the HUGO website generator, we realized that one of the most important additions that we provide is an actively maintained and simple glossary. Especially for people not yet very familiar with the technologies used, the pure number of terms can be intimidating and confusing. Our glossary helps by providing brief explanations of relevant terms used throughout the articles. An addition for which we modified the actual HUGO template is that we provide a taxonomy of articles rather than a pure folder structure to ease the navigation.
The knowledge-base is an on-going effort in which we appreciate feedback and contributions. In the presentation, we will take a closer look on the different materials provided for people developing software, people using software, and how people can actively contribute to the knowledge base through our peer-review process and material creation.

We envision “groupware” (like calendars, simple games, chat, collaborative docs, etc.) decoupled from reputation and group culture metrics (e.g. entry and exit rules, engagement incentives, likes or claps, visibility and feed ordering); in social platforms on the centralized web, these distinct functions are typically combined.To facilitate neighbourhoods, we are building a language and “interchange” for reputation data on Holochain such that users can connect a portable reputation extension to bundles of Holochain groupware.
Groups can then use the neighbourhoods framework to bundle p2p modules with reputational and cultural inputs that relate to their particular use cases and style of relating. This also means individuals’ reputation and activity records are stored on their devices, and so can be ported to other neighbourhoods and verified using Holochain’s gossip protocol for data validation. Neighbourhoods is centered on the Holochain ecosystem, but it may also be of interest to dWeb communities and projects aspiring to traffic in “richer” data than ownership claims & token counts - especially when those data support community collective intelligence.
Much of the system remains to be built, but the core language - rep_lang - has been integrated with Holochain. We’ll close with a brief demo showing one key aspect of the system: rep_lang computations being validated by multiple agents on Holochain.
I have reimplemented the Plan 9 cpu command in pure Go, available at github.com/u-root/cpu. It uses the ssh transport protocol for data, and the 9p protocol for file system traffic.
If you are used to ssh, cpu will look very similar, to the point of even honoring your .ssh/config! What's different is that when you cpu from your local note to a remote node, file systems of your choosing are visible on the remote node, mounted over 9p, connected to a server running in the cpu command itself. Translation: you don't ever need to talk to a sysadmin to get network mounts set up. Want to use programs from your local node, libraries from your node, and see your home directory? No problem, run with the default namespace. Is the node a different architecture, but you want to use your /home? No problem, just tailor the CPUNAMESPACE variable, e.g.: CPUNAMESPACE=/home:/bin=/arm/bin:/usr=/arm/usr:/lib=/arm/lib cpu cat /proc/cpuinfo. Want all this from power-on/reset? No problem, we embed kernels and a cpu daemon in flash on any of x86, ARM, ARM64, and RISC-V. Want to embed a cpu capability into your Go program? No problem there is a simple package that implements the Go exec.Command interface. Want to understand cpu? No problem, it's easy to read, consisting of 1164 lines of code for the client and 799 for the server.

Use the UI, the command line or an REST API to manage servers and desktop efficiently from a central place.
RPort is a comprehensive solution for remote management of servers and desktop systems. Even if they are behind firewalls, routers and NAT. RPort is built on the client-server principle, clients connect to the server, the management component, using a secure reverse tunnel. Unlike pure SSH, RPort is made for heterogeneous environments (Windows, Linux, macOS) and addresses four basic needs of system administrators:• Secure remote access from anywhere via tunnels and SSH/RDP/VNC/HTTP and other TCP connections• Script and command execution on target machines via a central dashboard.• Automation of recurring tasks such as updates, inventory, configuration and fine-tuning of systems.• Monitoring and logging system load and resource usage.
With RPort, a complete IT infrastructure with Windows, Linux and macOS systems can be managed via command line or a convenient web-based, central dashboard. The server component can be self-hosted or deployed in minutes using the automated installer provided by RPort.RPort is released under the MIT open-source license.

It was clear that a cryptographically secure chip level boot assistance was required, which guided subsequent patented ECC work at NeXT and Apple. Post Apple, in a “Social Purpose” company of his own, work has continued to fully realize this dream. The 1988 nanokernel had no threads and delivered messages across upcall channels to a thread simulation, yet that was unsatisfactory. The social element of phishing etc. is now the most feared secuirity breach, and in new work, discussed, the complete solution space is described, in the first half. New hardware is underway, solving such issues as weak memory models.
In the second half of the talk, key lockless queuing primitives are discussed that form the basis fo a multi-core actor runtime (MART) to subsume most if not all duties of the executive. Far richer than a hypervisor, the executive manages memory in new manners, in a memory safe programmer nature. In practice, a single core actor runtime (START), running across 32, 64 arm, x86, and extensa cpu architectures is available. The language and runtime are destined to the Open Source world, unless the larger project, TheDew, makes file systems and databases obsolete in its first rollout, which will include unhackable identity.

One of the pillars to promote open government at any level of government is that there should exist an open data policy. However, in the Mexican context, although one already exists at the federal level, very few states and municipalities have open data policies. This is partly due to the lack of knowledge and culture about open government, especially at the municipal level.
From Codeando México we work to promote citizen participation and open government, and we have carried out several exercises to co-create open data policies with the three levels of government: federal, state and municipal.
With this experience, we saw the need for the creation of an open data policy with a free use license. This policy, a work in progress, will be hosted in an open repository, will allow any level of government that wants to have an open data policy to adopt it and adapt it to their needs in a short time.
This project is nourished not only by the experience of Mexican civil society of the last 10 years but also, being an open source project, it will be in continuous evolution and improvement with the contributions of governments, civil society and any interested citizen.

Such applications are composed of components referred to as micro services.With the increasing number of micro services, it becomes increasingly difficult to understand how all the components communicate.
This is where Istio service mesh comes into play. Istio allows developers to manage and monitor network traffic between micro services and by providing features like mutual TLS, request retries or request circuit breaking. Vendoring these features from Istio helps keeping micro services focused on the actual application logic as they don't need to be implemented by the micro services.The IT industry has broadly adopted this architecture, but there are still plenty of legacy workloads running in virtual machines, which can't easily take the advantage of the features provided by service mesh. At least not until recently when KubeVirt introduced support for Istio service mesh.
Attendees of this talk gain insight into the concept of the Istio sidecar proxy. A short demonstration showing typical use case of Istio service mesh -- canary deployment -- is presented. Next, this talk explains subtle differences of network traffic routing between regular Kubernetes pods and containerized KubeVirt virtual machines, leading to the challenges that these differences pose for traffic proxying.Finally, the changes necessary to support Istio for KubeVirt virtual machines are explained and the resulting functionality presented using the same scenario, but with the workload running in virtual machines instead of Kubernetes Pods.
The takeaway of this talk is understanding of routing concepts behind Istio proxy sidecar with regular Kubernetes pods as well as with containerized KubeVirt virtual machines. Audience will have a chance to observe typical use case of Istio with both pods and virtual machines and get insight into the necessary changes that made this possible.

The data recorded by the detectors such as the CMS experiment are analysed by thousands of physicists all over the world. The CMS Collaboration has made openly available more than 2.5 petabytes of data on the CERN Open Data Portal, containing billions of recorded and simulated events.
Open Data are, however, only useful when accompanied by realistic usage examples. The sheer amount of data as well as the fact that the software used to analyse them is often more than ten years old poses several challenges. In this presentation, Clemens will discuss how the CMS Data Preservation and Open Access group tries to overcome these challenges so that potentially everyone could use the data to unveil hidden physics.

But running a cloud service requires resources so how can that be funded? An ideal solution would be simple, equitable and fair -- and not compromise the ethos of open source. We'll discuss our attempt at solving this puzzle, a funding mechanism we call cloud funding.Next, we'll introduce Unfurl, our DevOps tool for building reproducible, cloud-provider independent open cloud services and then look to future Web3 and decentralization technologies that make this possible -- specifically how blockchain-based decentralized data and remote attestation, transparent and reproducible open cloud services, and next-generation secure-computing cloud infrastructure all combine to provide the building blocks of a free and open cloud.

Confidential computing addresses this at the root by protecting data in use: sensitive workloads are run inside hardware-isolated and runtime-encrypted environments called enclaves.
We have developed the first open-source database based on MariaDB designed for confidential computing. EdgelessDB is a MySQL-compatible database that runs entirely inside Intel SGX enclaves.
In this talk, we'll introduce EdgelessDB and compare it to conventional databases as well as existing database encryption solutions. We'll explore the benefits, novelties, and why confidentiality is an important feature of a database. Finally, you'll learn about uses cases and how to easily get started.

However, we'd also like to restrict the capability of computers to do things we don't intend. These constraints present a problem: how our computers should determine our intention, when the software we use is written by others. Most programming languages ignore this problem, by running untrusted programs with completely open doors. Browsers run programs with a single policy that is mostly hard-coded (no file system access) but also complex, so that it's often unclear what is protected. In this talk I'll describe my attempts to come up with a model that is both flexible and easy to understand.

We'll go over how 1 to 1 calls work in Matrix today, our Jitsi widget we've used for group calls so far, and the changes we've made to support native group calls in Matrix.

Each project is given 2 minutes to present. In those 2 minutes, they should briefly introduce the project, explain what design help they need, and provide contact details so designers can reach them after FOSDEM.
The Open Source Design collective will use the information to submit a "job" for each project to the Open Source Design "jobs board" (https://opensourcedesign.net/jobs/), so that the request for design help reaches not just the designers in the room, but also the wider design community.
