Currently the design runs on FPGA verification platform via SDR (Software Defined Radio) methodology. With the design running, the FPGA board could become WiFi AP, WiFi client, ad-hoc node or sniffer. Besides the standard WiFi functionality (802.11a/g/n), it also has some special features, such as non-standard frequencies (<6GHz); CSI; IQ sample; configurable low MAC behavior; time slicing; etc.

We manage the project called "schul-frei", which aims to bring digitisation with free software to schools. We especially value the participation of youth in these projects, because they are the people which are affected by digitisation the most. Our educational concept is also based around the idea that young people should be judged by their abilities, not by age. They should learn to take responsibility and be independent. An example of this would be the AlekSIS project. It is (mostly) developed by adolescents from Teckids e.V. and from the school Katharineum zu Luebeck, where it is actively used.

As sensors and compute nodes are now (close to) ubiquitous, it follows thatthere is no longer a static or traceable relationship between ownership of aphysical processing unit and the personal identifiable data it processes.
A future internet architecture must take this into account, whilst respectingand protecting user's privacy and data protection concerns, also from aregulatory point of view. At the same time,sharing data in this proliferation of processing units also favours distributedapproaches over the web's decentralised architecture.
This session outlines the future the Interpeer Project envisions, and reportson achieved outcomes to date.

This was a deliberate tactical choice made by the OpenStack community years ago, forming a so called "Big Tent" for vendors to collaborate in to build Open Source cloud options. It made a lot of sense at the time to be honest. However, OpenStack today finds itself constrained by the large number of permutations it must support, ten years of software and backwards compatability legacy, and a decreasing investment from those same vendors that OpenStack courted so actively.
OpenStack Compute wasn't always like this though. The first public git commit had about 5,000 lines of code in it, and was surprisingly functional. What would a simpler and more opinionated IaaS compute component look like? Especially if it could take advantage of the general improvement of Open Source tooling in the last decade that OpenStack has driven? This was what I was pondering in late 2019 as I started to drift away from the OpenStack community for various reasons. Then, a series of natural disasters in Australia and globally presented me with an opportunity to cancel all my extracurricular activities and really give an experiment a go. That experiment is called Shaken Fist (as in old man shakes fist at cloud), is about the same size as the original OpenStack Compute commit, and is available at https://shakenfist.com. I'd appreciate the opportunity to discuss some of the simplifying assumptions made, what functionality is available, whether the experiment tells us anything interesting, and possible future directions.

DESCRIPTION:Management is difficult even under the best of circumstances and managing globally-distributed teams is even more so. With the global COVID-19 pandemic and the restrictions it forced on all of us, management is nothing like the best of circumstances.With the pandemic, suddenly everyone is a remotee – even people who have no experience in working remotely, and no desire to work in such an environment.In this talk, I’ll explore how the lessons learned from navigating a globally-distributed open source community can come in to play when managing a suddenly disturbed team. I’ll examine how taking a cue from open source communities can help managers handle this new landscape with flexibility, clemency, and above all, empathy.

At 5 years, it's still a young language, but some patterns are emerging that make it quite suitable for practicing your programming chops, or embark in some side project. In this talk we will introduce some interesting programming patterns that are seen, possibly, nowhere else, from "grammaroles" through "piggybacking objects".On the other hand, for a language where TIMTOWDI, there is more than one way to do it, talking about antipatterns might look paradoxical. So let's see how we get out of this catch-22 situation.

DESCRIPTION:The ever increasing need for the ability to easily customize, reproduce and migrate applications and workflows are steadily increasing amongst the High Performance Computing (HPC)community,as non-traditional HPC software environments and applications are starting to require HPC resources to tackle “real world” scientific problems. In addition,traditional HPC software are becoming more complex and are often deployed on multiple different architectures.In this talk, we discuss the issues associated with the deployment of containerized environments on secure HPC systems and how we successfully deployed traditional and non-traditional HPC applications on a secure large scale HPC production system with HPC specific containers.

One alternative is to rethink conventional processor design methodologies and propose innovative ideas to unlock additional performance and efficiency. In an attempt to overcome these difficulties, we propose a compiler-informed non-speculative out-of-order commit processor, that attacks the limitations of in-order commit in current out-of-order cores to increase the effective instruction window and use critical resources of the core more intelligently. We build our core based on the open source RISC-V ISA. The hardware and software ecosystem around RISC-V enables building custom hardware and experimenting new HW/SW cooperative ideas.

Embedded systems are tailored to a specific task aimed at minimizing resource and energy consumption (e.g. ADi PlutoSDR). Cross-compiling benefits from powerful personal computer computational resources and user-friendly interfaces while removing the burden on the embedded board of running the compiler. GNU Radio was ported to Buildroot to provide SDR enthusiasts access to the many boards supported by this cross-compilation framework. We demonstrate its use in a graduate course project aimed at developing an embedded network analyzer.

Fluence enables developers to host applications in the decentralized network and collaborate on live applications, reusing components and data. The protocol creates an open marketplace of compute capacity, so availability and pricing are not controlled by a single company and instead are driven by competitive market forces.
Applications are faster to build, easier to integrate, and more secure due to the enhanced composability. Business logic is incorporated into data packets orchestrating the execution of distributed components. Just as code collaboration creates better products, composition via network protocol enables live apps to be forked, expanded, or re-arranged into new and enhanced user experiences.

More than ever companies choose FOSS, however the world of safety is behind the curve. Software developed for safety applications often use old development practices and are closed source. Too commonly this code is seen as a competitive advantage, and having spent vast sums developing and analysing for safety, companies are reluctant to share their code. Ultimately this is to the detriment of everyone, and leaves us all vulnerable to unsafe software.
This talk will outline the problems with software in safety currently, detail how using FOSS practices could benefit not just the wider community but the leading industry suppliers, and talk about what we need to do as FOSS creators to convince industry that this is the way forward and make the software we use safer for all.

Much has changed since the early days, both within the project and in the world in which people build and monitor networks. Surprisingly little has changed with respect to the project's mission, even as major changes are happening with the project's corporate steward, The OpenNMS Group.
Newcomers will receive a brief background on the OpenNMS project, and longtime users will come up to date with the project's latest advancements and near-term plans. If you're interested in monitoring your networked resources with a free platform that integrates events, metrics, flows, ML-enabled correlation, and more in a multi-protocol, distributed, and fault-tolerant model, this talk might be for you.

DESCRIPTION:Software emulators are wonderful tools to study old computer systems for different purpose from running legacy application to retrogaming. This talk explores the context of digital preservation triggered by on-going work in a Belgian computer museum where emulators help in rediscovering old systems, maintaining/recovering knowledge on their design and sharing the experience with the audience without stressing fragile old machines. This talk aims at exploring and somehow engaging the audience about some simple questions from that perspective: where to look for emulators (MAME/MESS, specific development, javascript ports...) ? How to select one for some usage context ? And last but not least as emulators are themselves part of history: How to make sure/contribute to the sustainability of those nice piece of software on the long run ?

In addition, new paradigms such as Continuous Integration (CI) and Continuous Delivery (CD) allow organisations to do this much faster than before, empowering them to go to market ahead of the competition.
Despite its many advantages, the CI/CD ecosystem has its challenges. This session will discuss issues arising from the lack of interoperability across proliferating CI/CD technologies. We will look at end user case studies, including existing integration initiatives such as that between Tekton and Jenkins X. However, these initiatives are localised to the projects involved and do not address the challenges holistically. We will highlight the necessity, and greater sustainability, of a holistic approach to interoperability in the CI/CD ecosystem and invite attendees to join community efforts.

Over to you! DESCRIPTION:KernelCI has now been a Linux Foundation project for just over a year. Duringthat time, it has set the basis needed to fulfil its mission of being the defacto upstream kernel test system. We can now build many more kernels, runmany more tests and collate results from many more test labs. We also have agrowing team of core contributors, an on-going commitment from our membercompanies as well as more presence in the kernel community. Together, we aregathering the momentum needed to start a trend.
Now we need to make KernelCI a natural part of upstream kernel development andrealise its true potential. The CommunitySurveyin June 2020 showed there is great value and interest in having a moretest-driven workflow. While this is going to be a long-term goal, we alreadyhave a process to let the community shape the KernelCI tools according to theirown needs. This talk gives an overview of how it would work, essentially byallowing decisions to be based on feedback from the whole ecosystem(developers, maintainers, OEMs...). We want to hear from you!

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).
This year, however, we added production-grade native Matrix support for the first time to a major 3rd party chat system: Gitter (https://gitter.im) over the course of about 5 weeks. This talk will explain how we did it it, and show how easily other existing chat systems can extend their reach into the whole Matrix ecosystem; breaking open those walled gardens forever.

Veracruz uses Arm TrustZone, Intel SGX, AWS Nitro Enclaves, or the high-assurance seL4 microvisor, to provide a "neutral ground" within which a collaborative computation takes place, shielded from prying or interference by the host of the computation. The computation itself is realised by a WebAssembly program which sandboxes the computation, means Veracruz programs are portable across different isolation technologies, and allows multi-party computations to be quickly written in high-level programming languages with standard development tools. Potential use-cases for Veracruz include support for privacy-preserving collaborative machine-learning, privacy-preserving surveys, polls, elections, or auctions, and safely delegating computations from weak devices to more powerful devices, amongst many others.

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.
Fuzion was influenced by many other languages including Java, Python, Eiffel,Rust, Go, Lua, Kotlin, C#, F#, Nim, Julia, Clojure, C/C++, and many more. Thegoal of Fuzion is to define a language that has the expressive power present inthese languages and allow high-performance implementation and powerful analysistools. Furthermore, Fuzion addresses requirements for safety-criticalapplications by adding support for contracts that enable formal specification andenable detailed control over runtime checks.
The talk will explain Fuzion's motivation and present its main concepts, featuredeclarations and feature calls. It will not go into details of the syntax, butpresent Fuzion's approach to immutability, memory management and type inference.

A relative positioning device (mouse and trackball) provides the operating system with a vector of the cursor movement instead of its coordinates. As a result, different cursor acceleration formulas are breaking the coincidence of host and guest systems cursor. Fortunately, modern guest operating systems support absolute positioning devices (tablets), which provide real cursor coordinates. Desktop virtualization systems emulate such devices (USB Wacom tablet in case of QEMU), allowing the host cursor to control guest systems in so-called "mouse integration mode".
Until recent times mouse integration was available only if guest OS either has a driver from the virtual machine vendor or supports USB tablet. In all other situations, desktop virtual machines use "mouse lock mode". The host cursor is hidden, and the user can only interact with the guest system until some dedicated keypress.
Starting from version 1.9, QEMU had accepted our GSOC-developed patch intended for the osimeline project (HTML-based live demo of historical operating systems) and can emulate the RS-232 Wacom tablet as a "wctablet" character device backend.Currently, QEMU is the only virtualization system with such capabilities.

Fluence not only allows hosting services inside p2p network but also provides JS SDK for building web applications, which communicate with the services.After the introductory talk, we will dive right into something very practical. We will demonstrate the process of making a web application with Fluence JS SDK. We will start with an empty create-react-app project and work our way towards the fully functional solution.By the end of this talk, we will develop a text editor, which synchronizes it’s state and the user online status with collaborators over Fluence p2p network. The application will be interacting with two minimalistic services pre-deployed to Fluence: user-list and history, but all of the features will be implemented on client-side without any need to modify existing software.Expect a lot frontend and a lot of code in TypeScript!

Some tasks, like upgrading dependencies to the right versions, are still tedious and time consuming. There's also compatibility gotchas because of the lack of metadata.
This talk will start with a mention of the different problems that come with dependency management in real-world projects.Then it'll show how the developer tool refreshVersions (MIT licensed) tackles some of these issues in Gradle projects, saving a lot of time when upgrading dependencies.
Finally, I'll talk about what the future can be for dependency management, be it from new features in future Gradle versions, or tools or conventions that the community can create to improve the status quo.

DepClean performs a deep static analysis of the dependency network and suggests direct and transitive dependencies to be removed or excluded. Given an application and its build file, DepClean collects the complete dependency tree (the list of dependencies declared in the pom.xml, as well as the transitive dependencies) and analyzes the bytecode of the artifact and all its dependencies to determine the presence of bloated dependencies. DepClean also generates a clean variant of the build file in which bloated dependencies are removed.

The primary means of data exchange between architects, structural, MEPF engineers, cost planners, surveyors, program schedulers, asset/facility management and more revolve around a concept known as Building Information Modeling (BIM) in addition to CAD. Many of these tools do not exist as free software, or are drastically better, or are dominated by a monopoly vendor market with lock-in business practices.
Free software implementations of BIM have seen rapid growth in the past year, with new utilities available for OpenBIM building models, quality auditing, diffing, clash detection, issue management, facility management, environmental simulation, and more. This is supported by a newly formed community known as OSArch. Dion Moult, a main developer of the BlenderBIM Add-on, IfcOpenShell contributor, and one of the OSArch founders, will present a summary of these events, demonstrate how free software communities have collaborated and shared resources, and where this leads in the future. The BlenderBIM Add-on was recently awarded the buildingSMART 2020 Awards in Technology, the international standards body for BIM.

We will discuss questions of reliability and reproducibility, but also how tools are taking part in shaping which questions are being asked and how research is done in practice - making open source particularly relevant as a form of methodological transparency. Two aspects have become particularly important for our tool-making practice: the relationship with large platform companies and their Web-APIs as well as concerns about user privacy and legal compliance with regulations such as the GDPR. Our talk will address these in turn, scoping the issue and proposing ways forward.

Unlike other tracing backends Tempo can hit massive scale without a massive and difficult to manage Elasticsearch or Cassandra cluster. The current trade off for using object storage is that Tempo supports search by trace id only. However, we will see how this trade off can be overcome using the other pillars of observability.
In this session we will use an OpenTelemetry instrumented application to demonstrate how to use logs and Prometheus exemplars to find traces effectively in Tempo. Internal Grafana metrics will also be shared as we all discuss how to scale tracing as far as possible with less operational cost and complexity than ever before.

Thus more and more users and customers are starting to consider using these datacenter hardware options for their business. Big Data is one of the most important areas.
On the contrary, the open source ecosystem for Big Data on ARM is not that perfect: most of the software in the Big Data ecosystem does not care too much about running on ARM in advance, or developers have not officially tested their codes on ARM, and there are a lot of unsolved problems. In order to make those software solutions able to run on ARM, one has to search and read tons of articles and to do a lot of patches and build a numbers of dependencies on their own. And once the upstream changes or upgrades, there might be new problems since it is not tested on ARM in upstream. All these challenges made users concerned to use ARM for their business.
In order to change this situation and make the Big Data open source ecosystem more friendly to ARM platform and its users, our team started by proposing adding ARM CI to those open source projects. By doing this, the projects will be fully tested on ARM and also all future changes will as well be tested on ARM. In the process, we fixed a lot of problems directly in upstream, which benefits all users. And then, we started to perform performance comparison tests between ARM and x86, to give users an overview of the status. And there are also large numbers of TODO items, for the future.
In this session, you can learn the current status of ARM CI for Big Data ecosystem projects like Hadoop, Spark, Hbase, Flink, Storm, Kudu, Impala etc. and our efforts on fixing ARM related problems. We will also introduce our future plans.

As such a restriction,FDWs for schemaless databases need to change the foreign table definition, when some columns are added in remote database.This restriction can not take full advantage of the schemaless feature. In this time, we considered implementing FDW that does not require changing the external table when columns are added onexternal database. I would like to introduce this study based on the time-series database InfluxDB as schemaless database.

This talk will introduce the new Adaptive Query Execution (AQE) framework and how it can automatically improve user query performance. AQE leverages query runtime statistics to dynamically guide Spark's execution as queries run along. The talk will go over the main features in AQE and provide examples on how it can improve on the previous static query plans. Finally, we'll present the significant improvements we have seen on the TPC-DS benchmark with AQE.

In particular, use of third-party libraries or the Ada standard libraries may weaken the analysis, if the relevant properties of the library API are not specified.We progressively added contracts to some of the GCC GNAT Ada standard libraries to enable users to prove additional properties when using them, thus increasing the safety of their programs. In this talk, I will present the different levels of insurance those contracts can provide, from preventing some run-time errors to occur, to describing entirely their action.

The library is designed to be extensible such that it can be adapted for various movement analysis tasks. The library has been developed as part of a collaboration between HERE Technologies, Eindhoven University of Technology and Utrecht University under the Commit2Data program.
This talk is intended to showcase the scalability of MoveTK to large geo-spatial data sets. Moreover, through visualisations, we will demonstrate the various movement analysis algorithms that are available in MoveTK. Any scalable movement analysis task can be based on three fundamental building blocks: (a) the representation of (geo-)spatial movement data (b) the shape and specifically geometric aspect of movement and (c) algorithms that have theoretical bounds on their time and space complexity. Therefore, we will present the design decisions adopted in MoveTK, that allows seamless interoperability between these fundamental building blocks.

Aquamarine language. DESCRIPTION:Aquamarine is the multi-process composition medium based on pi-calculus, designed for distributed applications/backends, both in private deployments and open networks. Aquamarine scripts define the topology of the execution (when and where to move control flow) and data dependency graph (what results and what arguments to pass where), essentially describing the composition of (micro)services, e.g. using one service's output as another service's input. The language primitives are based on pi-calculus operations describing certain topological effects and secured by cryptographic signatures of involved peers. The Aquamarine approach allows building distributed systems of any complexity, effectively expressing network behavior.

Will cover a simple contrived data race, entirely in user land, to demonstrate the basics. Then we will move onto real world examples within the kernel, including when a delay bias is required to ensure a particular chronological order of events.
Fuzzy Sync was developed for reproducing Linux kernel bugs, however it may be used to collide events in user land, another kernel or other contexts. No particular kernel features or instrumentation are required. The Linux Test Project is a large test suite for the Linux kernel and POSIX. Most of the tests are stand alone executables which run in user land and interact with some low level kernel interface. Fuzzy Sync is primarily used in regression tests which attempt to reproduce a particular bug. This ensures the bug is not reintroduced and indicates if a patch needs back porting to older kernels.

Some of these expectations are explicit in contributing files, whereas others are implicit and more of a cultural behaviour we as a group have taken on over the years. Governments and civil servants come from a very different background and when they start developing publishing software in the open under a free licenses, these cultures may meet, and sometimes even clash. We know that individual volunteer contributors differ from corporate contributors, how do public workers as contributors fit into this.
How public workers contribute has to do with how they operate, and how the society expect them operate in other fields of their operation. If not understood properly, this can lead to frustration of a FOSS contributor who want to make a useful contribution to a codebase developed by a public organization. In this talk we will try to give you the tools and the mindset that will help you succeed when submitting those merge requests.
"As a volunteer I am making contributions to a codebase managed by a public organization and it's behaving differently than the FOSS I am used to and here is why and how to adapt."

Modern enough that it leapfrogs the capabilities of the OO systems of many other dynamic languages. I’ve been stealing ideas from Stevan Little, Damian Conway, and anyone else foolish enough to leave their ideas lying around. I have no pride. Sawyer’s expressed interest and it's likely it will go into the Perl core, though with the upcoming Perl governance changes, the timeline is unclear.
I’m not going to beat around the bush: writing object-oriented code in Perl is a shambolic mess. Some people want to use bless and hand-roll everything, others insist upon using Moo/se, while still others others reach for Class::Std, Spiffy, Class::Tiny, some in-house monstrosity their company uses and so on. You have to relearn it again and again and again. It's time to put this embarrassment aside.

For instance, a CD system receives an event that describes a new version of an application, and it runs a workflow in response.When the workflow starts or when it reaches completion, the CD system generates events for the benefit of other processes that may want to trigger tests against the newly deployed application version.In this short presentation, we introduce the "Events in CI/CD" interest group, part of the Continuous Delivery Foundation, and its mission of standardization and interoperability between CI/CD systems via events.

This talk provides a deep dive on recently added BPF kernel as well as Cilium extensions for Kubernetes environments which significantly reduce application tail latencies with the help of the earliest departure time (EDT) model for egress bandwidth management. Furthermore, recently added BPF redirection helpers are discussed which offer a low-latency switch into Pod network namespaces. Last but not least the talk also covers how Cilium's BPF kube-proxy replacement improves reliability for its high-performance XDP-based north-south service load-balancing through a BPF-based Maglev consistent hashing implementation. We'll discuss our path towards implementing these features, our lessons learned as well as future follow-up work.

In multi-party settings in which the parties may not always fully trust each other, attestation of multiple pieces of code or data images via these means is cumbersome and inefficient. For example, consider the case of a secure cloud service running a JavaScript interpreter, which interprets a third-party script, in which case both, the interpreter and the script, can interfere with each other's attestation evidence as they share an address space. Similarly, a group of users may want to compute a shared result over all of their combined data, but without sharing their data with each other. Attestation in such scenarios is greatly simplified by a technique called Extended Enclave Initialization Data (EEID), which provides a secure and convenient means to combine all required attestation evidence, and to automatically re-sign images (with a well known service key) during enclave startup to ensure that all of the code and data is loaded and attested appropriately. An added benefit is that even single-party applications can use this technique to automatically re-sign enclave images with modified configuration settings (like memory size and thread count), independent of, or in addition to, underlying TEE support for configuration changes. EEID is currently available as an experimental feature for SGX enclaves in the Open Enclave SDK and it is used in multiple prototype services at Microsoft.

However, to develop games with JavaFX effectively, numerous domain-specific concepts are needed.
To address this need, the FXGL game engine extends JavaFX and brings support for real-world game development techniques. These include the entity-component model, A* pathfinding, particle systems, sprite sheet animations, and many other features.
As a result, JavaFX (including Java and Kotlin) developers can produce games more quickly and more effectively with FXGL.

However, most people use these tools in temporary scripts for a one-time tweets collection. Moving to a robust application for collecting and indexing tweets over long periods of time requires some programming knowledge that most social science researchers do not master. In order to meet this need, the medialab has developed gazouilloire, a tool that makes it possible to easily configure the collection parameters (keywords searched, language of tweets, location of tweets, etc.) and can then be launched from the command line.
Gazouilloire combines two methods to collect tweets from the Twitter API ("search" and "filter") in order to maximize the number of collected tweets, and automatically fills the gaps in the collection in case of connexion errors or reboots. It also provides a large range of features that are not directly available from the free Twitter API: collecting during specific periods of time, resolving redirected urls, downloading only certain types of media contents (only photos and no videos, for example) or unfolding Twitter conversations. The user can then choose to export the tweets in csv format, and select the fields that will form the columns of the table.
Social science researchers have already used gazouilloire for a wide variety of studies: measuring online activity during COVID-19 lockdown, studying the public discourse of anti-vaxxers, or monitoring urban nature policies, among many others...

In addition to this, empirical evidence has shown that these package managers adhere to a large extent to semantic versioning principles. Packages that are still in major version zero are considered unstable according to semantic versioning, as some developers consider such packages as immature, still being under initial development.
This presentation reports on large-scale empirical evidence on the use of dependencies towards 0.y.z versions in four different software package distributions: Cargo, npm, Packagist and RubyGems. We study to which extent packages get stuck in the zero version space, never crossing the psychological barrier of major version zero. We compare the effect of the policies and practices of package managers on this phenomenon. We do not reveal the results of our findings in this abstract yet, as it would spoil the fun of the presentation.

The tool first identifies computational units which, in our terminology, are the atoms of parallelization. Then, it profiles memory accesses inside the source code to detect data dependencies. Mapping dependencies to CUs, we create a data structure which we call the program execution tree (PET). Further, DiscoPoP inspects the pet of a program to find parallel design patterns and parallelization suggestions in terms of OpenMP constructs and clauses. By far, DiscoPoP detects doall, reduction, pipeline, task parallelism, and geometric decomposition in a program.
We used DiscoPoP to create OpenMP versions of 49 sequential benchmarks and compared them with the code produced by three state-of-the-art parallelization tools: Our codes are faster in most cases with average speedups relative to any of the three ranging from 1.8 to 2.7. Moreover, we analyzed the LULESH program and an astrophysics simulation code with DiscoPoP. In LULESH, we identify most of the parallelization opportunities which have been parallelized by expert programmers manually. In the astrophysics code, DiscoPoP finds unexploited parallelism opportunities and achieves a speed-up of up to 35%.
DiscoPoP is released as an open source software and can be downloaded from:

It becomes harder and harder when the number of databases to manage raise continuously. At OVHcloud, a major cloud computing provider in Europe, we used to manage such changes approximately. With our startup mindset, we used to yell "Who can ALTER my database?" and hope for someone sitting next to you to answer. Database engineers were used to copy paste bunch of SQL statements on production databases directly. What happens if a bad character is inserted? What if there is no transaction in the script? What if you run the migration on the wrong database? It works, sometimes. Lots of tasks are boring. This one was on top of our list. In this talk, you will discover our feedback on how we have reduced efforts, time and human errors by automating databases schema migrations using git, code reviews, CI/CD, migration tools, service discovery and automation systems at the OVHcloud scale.

One can create their own types, operators, access methods, etc. or use powerful PL/pgSQL language to write functions, extensions, and so on and so on. Everything is thoroughly documented, supported and ready to use. However, there is also a very intimate extensibility layer, which allows external developers to peek right into the PostgreSQL core — hooks. For some reason this topic is not covered enough by official documentation.
First, this talk will focus on which core hooks do exist, which options they provide for potential developers, and which PostgreSQL extensions get use of them to achieve an additional out-of-core functionality.
Next part will show an example of how one can consistently distribute some DDL across multiple PostgreSQL instances. This is based on experience got from Postgres Professional's take on sharded Postgres (first alpha version of shardman extension is available here).
Finally, there will be demonstrated a tricky way to extend CREATE TABLE syntax using PostgreSQL hooks without even touching the core. So one was able to do, e.g.:
CREATE TABLE users ( id int not null, name text) WITH (distributed_by = 'id', num_parts = 12, colocate_with = 'companies');We made the Web accessible to human. What about making the web (of data)accessible to computers?Publish open data could be struggling. Deposit a CSV file on a web server is not enough. The data model used should be explicitly defined.
The Linked Open Data (https://www.w3.org/standards/semanticweb/data) solves this with:* standardized implementation format (RDF)* standardized data access (Content negociation, SPARQL endpoint)* standardized data indentification (URI, data model as data)
For example all the data from the Bibliothèque National de France (national library of France) are widely accessible by using these standards.This allowed the development of data federation initiatives, such as Europeana (https://www.europeana.eu).
CubicWeb is a semantic web application framework, licensed under the LGPL,that follows Linked Open Data best practices.During this presentation we will discuss about Linked Open Data benefits,and how CubicWeb could be used as a "on shelve" framework to do so.

What information can you get out of it, and to what degree does this information help to troubleshoot operational issues? What if you want/need to log all the queries? That may bring heavy trafficked databases down.
At OnGres we’re obsessed with improving PostgreSQL’s observability. So we worked together with Tetrate folks on an Envoy’s Network Filter extension for PostgreSQL, to provide and extend observability of the traffic inout a cluster infrastructure. This extension is public and open source. You can use it anywhere you use Envoy. It allows you to capture automated metrics and to debug network traffic. This talk will be a technical deep-dive into PostgreSQL’s protocol decoding, Envoy proxy filters and will cover all the capabilities of the tool and its usage and deployment in any environment.

DESCRIPTION:What do you do when the interest of your different constituencies are in conflict? Who do you favor and why?
The 4 Freedoms and the OSD were designed for a small community of hobbyists. They offer little help when it comes to addressing the challenges open source faces today.
Does open source need a W3C-inspired "priority of constituencies?"
In this talk we’ll dig into the priority of constituencies, see how it could apply to open source, and get some interesting insights out of doing so.

Common assertions such as “the use of CRISPR technologies has skyrocketed in laboratories all around the world since 2012” can now be easily verified in both quantitative and qualitative perspectives using those platforms. Such services as Elsevier’s Scopus propose inbuilt functions to explore corpuses chronologically and geographically. They don’t, however, allow for hand curation and enrichment of the corpus. This lecture advocates for a solution to this methodological issue using PANDORÆ, a free and open source software designed for that purpose. PANDORÆ requests corpuses from the Scopus API, enriches its data by geolocating each document’s affiliations, and then uploads the resulting dataset to a Zotero library. The user is then free to curate the corpus, adding, editing or removing items. PANDORÆ allows downloading it back from Zotero to its internal databases, and to display the enriched corpuses on a map, on a timeline, or as an author-directed force-layout network graph.
This presentation will also introduce more advanced PANDORAE features, such as displaying Twitter dataset obtained through Gazouilloire, mapping web entities loaded from Hyphe and scraping biorXiv results using Artoo.

The goal of buildbot.mariadb.org is to ensure that each change is properly tested on all supported platforms and operating systems. Our new CI uses almost exclusively latent workers, more exactly Docker latent workers. In this talk, I will present a main overview of the CI infrastructure, the advantages of using latent workers and talk about the challenges that we encountered along the way. This includes a broad range of aspects, ranging from misconfigurations to Buildbot code changes to ensure that everything runs smoothly.

This year I propose a demo about how to create a public website with XWiki, and use XWiki like a content management system (but a collaborative one). The appeal of XWiki for such a usage is the possibility to integrate all usages in a single tool (intranet - see last year's talk - or any other content centric collaborative platform - see the talk from 2 years ago), while not completely missing the presentation features of "classical" content management systems.

One of these things is the C++ library that is used to implement the WebRTC functionality such as audio, video and data channels in the Chrome browser.The library is a complex beast with more than a million lines of code and a history dating back to 2004. It implements a wide range of network protocols and audio/video codecs.The interaction between WebRTC and Chrome is heavily influencing the how features are developed, reviewed and shipped to millions of users.In order to successfully contribute one has to understand both the tooling as well as the review process and how changes get into Chrome eventually.
I am going to explain that process using two examples:- a trivial logging change- a feature to enable audio redundancy
The logging change, while trivial, is a great example of the mechanics how a change gets uploaded, reviewed and shipped.
Audio redundancy is a complex feature that attempts to solve a very hard problem, audio quality. Getting that feature considered even required data about the efficiency.The implementation turned out to be relatively complex, involving ten different changes in total.While implemented in the WebRTC library, it has not yet been shipped enabled by default in Chrome since evaluating and tuning the implementation at scale in the real world is difficult.
Contributing back to the WebRTC library may be difficult, it is possible and contributions are welcomed. We just need more of them!

DESCRIPTION:Iaso is a platform created to support geo-rich data collection efforts, mainly in public health in emerging countries. The key feature that it supports is that any survey is linked to an organizational unit that is part of a canonical hierarchy. Each one of these org. units can have a location and a territory. The mobile data collection tool can be used to enrich this hierarchy with additional GPS coordinates, names corrections, etc ... which can then be validated by officials of the organizations in question through the web dashboard. This leads to continuous improvements of the geographic references available through the routine activities already planned (e.g. locating and registering health facilities while investigating malaria cases).
The tool has been used in multiple data collection efforts, notably in the domain of Performance Based Financing of health services in D.R. Congo, Niger, Cameroon and Nigeria and is more and more used to compare multiple versions of official organisational hierarchies when a canonical one needs to be rebuilt. We are for example working on such efforts to rebuild a school map for DRC with the NGO Cordaid. To help for this type of project, we provide location selection interfaces, multiple levels of audits and an API open to data scientists for analysis and mass edits.
This presentation will demo the main features of the platform, and give some context about its creation.

It will be based on personal experience with a team project that aimed to analyze the Twitter follow graph of last year’s FOSDEM and CHAOSScon participants. The project used open source tools and agile management: data was collected with a command line tool (Twarc), network visualization was done with Gephi, and Framagit provided a collaborative framework for managing code, data, visualization and text.
Implementing this project led to insight about what it takes for social scientists who have minimal tech knowledge and culture, to practice open research with FLOSS tools. This talk will specifically address three types of challenges I faced : training, documenting, and collaborating.

Exciting advancements in the open source Vulkan Project are enabling developers to take advantage of general purpose GPU computing capabilities in cross-vendor mobile and desktop GPUs including AMD, Qualcomm, NVIDIA & friends.
In this talk we will learn to write GPU accelerated algorithms which will be able to run on virtually any GPU hardware, including non-NVIDIA GPUs. We'll introduce an intuition and key concepts around GPU computing, as well as show how you can get started with the Vulkan Kompute framework with only a handful of lines of C++ or Python code.
Throughout the talk we will also dive into the GPU computing terminology around asynchronous & parallel workflow processing, cover the core principles of machine learning data parallelism, explain the hardware concepts of GPU queues & queueFamilies, and talk about how advancements in new and upcoming graphics cards will enable for even bigger speedups (such as the NVIDIA Ampere GA10x architecture which will support up to 3 parallel queue processing workloads).
In more detail these are the topics of the talk:
• GPU computing intuition, hardware and foundations
• Deeper dive into the OSS Vulkan C++ SDK enabling cross-vendor GPU computing
• The C++ Kompute Framework and its architecture which augments Vulkan
• Simple C++ Example with Kompute
• Deeper Optimizations (Batch Commands, Asynchronous and Parallel Workloads)
• FamilyQueues for Hardware-Parallel Workloads
• C++ Example for FamilyQueue Hardware-Parallel Workload

With this presentation, I will bring you a short journey as a result of my experience as DBA in the usage of the Percona Operator for MySQL.We will see from one side failures, misunderstanding and some frustration. From the other side a learning process that brings me to have better comprehension of the possible utilization and the best way to achieve it. Finally my personal considerations.

With a database service, the HA properties apply to both the service itself and of course to the data set.
In this talk we learn how to think about specific HA needs of your production environment and how to achieve your requirements with Open Source tooling when it comes to your database of choice, PostgreSQL. In particular, we dive in many options that could be implemented for Postgres to evolve its offering from being a toolset to being “batteries included”. What does it mean in the context of HA? How to achieve it?

We provide the open standard and open source tools to democratise communication away from the proprietary closed communication silos (Slack, Discord, Telegram, WhatsApp etc) that currently dominate.
In this talk, we'll explain all the features we've been adding to let Matrix scale to support massive virtual communities such as FOSDEM itself, Mozilla, KDE and others. This includes Spaces: the ability to group rooms into a hierarchy, for ease of discovery and management; Widgets: the ability to add arbitrary webapps to chatrooms to provide dashboards of additional functionality (e.g. the FOSDEM livestreams and video conferences); Threading: the ability (at last!) to support threaded conversations in Matrix; and Decentralised Reputation - the ability to empower users to tune out content they dislike on their own terms. Our goal is to ensure no open source project ever uses Slack/Discord/Telegram to collaborate ever again. Finally, we'll give a quick tour of the FOSDEM-specific work we've done in order to run FOSDEM 2021 on Matrix!

It can be seen as a way to enforce existing power structures. The very act of making software entails describing exactly how the system can be used and for what. Furthermore, ever more data about the usage of systems is gathered. This combined with machine learning has given rise to a whole new class of systems that can be very hard to reason about. Especially given that the data or the algorithms can be controlled or bought by external parties.
What if that doesn't need to be the case, what if we could make software that is both subjective and in control of the user. I will be presenting one such system - Scuttlebutt, detail how it is different from the systems described above, and also different from federated systems.
In this particular talk, we delve into how Scuttlebutt apps can be built straight in the browser, no additional application needed. With the expert at hand there will be plenty of time to dive in and explore your own ideas once learning how to build your own SSB apps in the browser.

However, PaaS solutions quickly become cost-prohibitive for compute- or memory-intensive applications. In this talk, I’ll demo an open source infrastructure automation toolchain based on Ansible, Github Actions, Vagrant, Packer, Terraform, and Sentry. Once instrumented, this toolchain incurs a $0 recurring cost and can be safely and trivially scaled up. Each component of the toolchain requires minimal operational expertise and is managed through a UI. State-change notifications are routed to email or a Slack channel, ensuring everyone stays on the same page. Test, deploy, monitor, and scale transparently, and with confidence!

Many languages that apply this style attempt to minimize or eliminate side effects by describing what the program must accomplish in terms of the problem domain, rather than describe how to accomplish it as a sequence of the programming language primitives. Declarative programming is the basis for functional programming, logic programming and dataflow.

The main feature of our framework is to provide a high level of abstraction over the platform-specific TEE layer and over the secure communication between different modules, leaving to a developer only the task to write the application’s logic. We provide a notion of event-driven programming to develop distributed enclave applications in Rust and C for heterogeneous TEEs, including Intel SGX, ARM TrustZone and the open-source Sancus. This heterogeneity brings our work to a broad range of use cases, which include cloud processing, mobile devices and lightweight IoT. Our framework ensures strong security guarantees based upon mutual attestation of security-critical software components.

That is changing with the introduction of Compose for Desktop, which will allow building application UI for Linux, macOS and Windows.

In the best case scenario, a downstream user detects it early thanks to good tests, files an issue, and the maintainer can fix it before too many people have upgraded. Other scenarios involve various degrees of brokenness and games of "is it broken for everyone or just me?".
Renovate Bot is an open source dependency automation tool but which also is run as a free app on github.com, where it is installed into almost 200,000 repositories. A feature called "Merge Confidence" helps downstream users know if a release is likely good or not based on automatically sourced crowd data (tests, deployments, rollbacks). Now we are planning to turn the focus upstream to help open source maintainers get an early indication of accidentally breaking releases and even provide a mechanism for downstream users to opt into silent pre-release testing so that major features can be smoke tested downstream before release.

DESCRIPTION:2020 was a very bad year for most of us, under the shadow of all that was going on there was a troubling trend we all need to be aware of: the erosion of the classic open source model and values. For years vendors have been slowly chipping away at the freedom and openness provided by open source, this year saw unprecedented changes to how people view and value OSS. From licensing changes to as a service exclusive, what was open is no longer. Is this being driven solely by the cloud? or is this purely corporate greed and others viewing open Source as a successful business model to replicate? Let's not only discuss but bring to light the trouble trends that threaten open source projects and development as we know it.

Part of this discussion relates to how the new paradigmincorporates support for accessing accelerators, e.g. GPUs, FPGAs. That kind ofsupport has been made available to traditional programming models the lastcouple of decades and its tooling has evolved to be stable and standardized(eg. CUDA, OpenCL/OpenACC, Tensorflow etc.).
On the other hand, what does it mean for a highly distributed applicationinstance (i.e. a Serverless deployment) to access an accelerator? Should thefunction invoked to classify an image, for instance, link against the wholeacceleration runtime and program the hardware device itself? It seems quitecounter-intuitive to create such bloated functions.
Things get more complicated when we consider the low-level layers of theservice architecture. To ensure user and data isolation, infrastructureproviders employ virtualization techniques. However, generic hardwareaccelerators are not designed to be shared by multiple untrusted tenants.Current solutions (device passthrough, API-remoting) impose inflexible setups,present security trade-offs and add significant performance overheads.
To this end, we introduce vAccel, a lightweight framework to expose hardwareacceleration functionality to VM tenants. Our framework is based on a thinruntime system, vAccelRT, which is, essentially, an acceleration API: it offerssupport for a set of operators that use generic hardware accelerationframeworks to increase performance, such as machine learning and linear algebraoperators. vAccelRT abstracts away any hardware/vendor-specific code byemploying a modular design where backends implement bindings for popularacceleration frameworks and the frontend exposes a function prototype for eachavailable acceleration function. On top of that, using an optimized paravirtualinterface, vAccelRT is exposed to a VM’s user-space, where applications canbenefit from hardware acceleration via a simple function call.
In this talk we present the design and implementation of vAccel on two KVMVMMs: QEMU and AWS Firecracker. We go through a brief design description andfocus on the key aspects of enabling hardware acceleration for machine learninginference for ligthweight VMs both on x86_64 and aarch64 architectures. Ourcurrent implementation supports jetson-inference & TensorRT, as well as GoogleCoral TPU, while facilitating integration with NVIDIA GPUs (CUDA) and IntelIris GPUs (OpenCL).
Finally, we present a demo of vAccel in action, using a containerized environmentto simplify configuration & deployment

It goes well beyond many CRM, ERP, PM, etc, offerings which are good at what they do but typically narrow in focus, by giving users a wide mix of hundreds of tools in many categories - Front-end, Back-end, Databases, Admin and Mobile. Big 'Features', supporting 'Features' and countless small but handy plugins all combine, allowing users to literally create any app for any business sector. This less focused and 'utilitarian' nature is more relevant than ever as Tiki resolves a problem so many organizations today are struggling to solve - too many apps with little to no integration between them. Tiki offers so much, in fact, that it allows individuals to become Full Stack Developers - this is my story and where I'm at after using Tiki for over 8 years. However, since it's FLOSS software it also fits developers like a glove, as unlike proprietary 'No-Code/Low-Code' offerings where even developers would need to submit Bug Reports and wait for responses, Tiki allows them to get 'under the hood' and debug complex configurations at their convenience.
This presentation briefly covers a few 'No-Code/Low-Code' development tools in each of the 5 categories that Full Stack Developers need, various user roles and the levels on which they can participate as well as gives examples of 'No-Code' and 'Low-Code' within Tiki.

Well... soft of. But what's the price to pay in terms of usability? How are you actually able to use an OS like that for common everyday user (web browsing, document editing) and developer (writing and building code) activities? Come to this talk and learn how it's being to use one of them, i.e., openSUSE MicroOS, as a daily driver since the last few months and how that compares with using other similar solutions, like Fedora Silverblue and Endless OS.
It is impossible to bring every idea, every innovation, and every improvement you can think of to fruition. Doing a little less allows you to honor the finite amount of time each person can give to your cause or project or workplace. But how do you start cutting those todo's down to a manageable level?

Besides the general equipment of schools with free software, an equal involvement of students in the development is for us important. One of the solutions presented by the project schul-frei is AlekSIS, a web-based school information system that is being developed jointly by Teckids e.V. and students of the Katharineum in Lübeck. The django-based platform provides data structures that can be used by separately developed apps. The special feature of this project compared to other information systems is that apps can be developed that cover specific application areas of a school. AlekSIS is a framework for apps that can be developed together with students in computer science classes, for example, because the development of such apps with python is easy to follow.Since AlekSIS is just a part of the free software curation, it can be excellently combined with other services or network accounts that are used in school.In our talk we will show, how this framework concretely looks like and how people can contribute to this project or use this system, for example at schools.

Companies like BackYard Brains made it accessible for all at a relatively affordable price, with their initiative of neuroscience for all. The price of their device and the ease of usability it comes with is pretty good for a school student who's just looking for an introduction to neuroscience but, the resolution of Arduino's ADC (10bit) doesn't allow it to be used for any real neuroscience research project. The company called OpenBCI also creates some good hardware for Biopotential amplification (4/8ch 24bit) and their hardware is much more capable but, it's very costly and certainly not for everybody.
As an engineer myself, I believe we can create much cheaper hardware for Brain-Computer interface devices than currently available in the market without losing any signal quality. I have started working on some prototypes already and one of the devices is called BioAmp v1.5 (github.com/upsidedownlabs/udlabsBioAmpv1.5) which takes benefit of the already available high-resolution ADC input of your computer which is normally used to record audio. The device basically converts the muscle into an audio source and provides us with the option to directly listen to it using earphones OR to visualize/record the signal on our mobile/laptop using Audacity/BYB Spike Recorder.

Consequently, using Terraform to maintain Kubernetes clusters and resources is a very common use-case. And it requires careful integration of many moving parts, from Terraform providers and modules, to CI/CD pipelines and triggers.
However, despite this being such a popular use-case, teams previously had no alternative than writing everything from scratch. On the software development side we use frameworks to avoid reinventing the wheel for similarly common use-cases. But for the less mature infrastructure as code ecosystem use-case specific frameworks are a new concept.
This talk will introduce Kubestack. An open-source framework for Terraform, that brings the developer experience of frameworks from application development to infrastructure as code. Get an overview of how you can use the framework as a foundation to build even advanced multi-cloud and multi-cluster Kubernetes automation. And how Kubestack's GitOps workflow allows teams to reliably suggest, review, validate and apply changes to their infrastructure environments.

GNUEmacs as a long history, and is still widely used and supported by avery active community of users and developers. A very popular featureof GNU Emacs is Org-mode which, at its core, offers a markup languagesimilar to Markdown.
Following a brief introduction to Org-mode, this presentationdemonstrates its use for reproducible research: straightforward mixingof prose and code, execution of code blocks as well as display of theresults. With Org-mode, GNU Emacs is turned into a computationalnotebook which functionalities goes well beyond popular alternativessuch as Jupyter. Code blocks are not restricted to a particularprogramming language and data can be passed between them: generatedata in C, analyse it in Python, visualise it with R, all in onesingle executable document. Moreover, Org-mode documents are nothingbut plain text, making them inherently portable, sustainable, andsuited to version control - crucial qualities for academic research.Moving on, I illustrate the export of Org-mode documents to richerformats: PDF, ODT, HTML and many more - all from within GNU Emacs.Lastly, I broaden the scope of this presentation and discuss the opennature of GNU Emacs itself. Indeed, GNU Emacs is free (as in freedom)software under a copyleft license. This ensures that GNU Emacs remainssustainable, community-owned software: GNU Emacs will never be"discontinued" or its features reduced inside a "community edition".

In this talk, I will give a brief introduction to SigDigger, what are its use cases, and why it is a reasonable option with respect to existing alternatives. In order to better illustrate these use cases, I will perform a live demonstration of its features and capabilities and give some real-time performance figures. I will then describe its internals, how the demodulator pipeline is implemented, why it is so fast, and why it could be even faster. I will finish with the mid-term goals of the project, WIP, and a request for collaboration for anyone who could be interested in making this software grow.

Thanks to the insertable streams feature which shipped in Chrome at just the right time, we were able to ship a working E2EE implementation in a reasonably short amount of time.
In this presentation we'll walk through all that was needed, what our plans for the future are and how others can leverage what we learned to add E2EE to their WebRTC applications.

Open source has core principles that make it rely on collaboration between contributors and companies in order to achieve a common goal. To attain more collaborations, onboarding in most open source communities should be considered a priority. Oftentimes, beginners who are new to open source projects develop cold feet a short while after joining a community because they are not properly onboarded into the community. Onboarding plays a major role in the performance of and productivity of contributors. In this session, I would like to talk on:- What is quality onboarding?- Effects of poor Onboarding in a community-The need for improved onboarding- How onboarding can be improved?- Impact of quality onboarding

Aligned with the grand trends towards heterogeneous and near-data computing, computational storage has gained tremendous momentum and led to an on-going industry-wide effort on expanding the NVMe standard to support CSD. The first generation CSD products have built-in transparent compression, which can be deployed into existing computing infrastructure without any changes to the OS and applications. This proposed talk will discuss and present: (1) brief introduction to commercially available CSDs with built-in transparent compression, (2) experimental results that show, by replacing leading-edge normal SSD with CSD, one could reduce the storage cost by over 50% and meanwhile achieve 30% better Postgres TPS performance, and (3) experimental results that show CSD could meanwhile significantly reduce the Postgres write amplification, which enables the use of emerging low-cost QLC flash memory to further reduce the system storage cost. Finally, this proposed talk will discuss the potential of leveraging CSDs to improve the efficiency of important operations in Postgres.

We then review the history of high-speed software dataplanes. We explain the evolution of graph-based (software) network packet processing from the early 2000s with the emergence of the Click Modular Router, and continue up to today's ecosystem, where many similar systems, such as VPP, BESS, and FastClick, coexist. We analyze the upcoming challenges to process packets at multi-hundred-gigabit-per-second rates. We argue that multi-hundred-gigabit networks should prevent performing memory accesses, as the interarrival time of packets is shrinking to a few nanoseconds, i.e., smaller than L3 cache access time. For instance, a 100-Gbps NIC could receive a minimal-sized frame every 6.72ns while operating at its maximum rate.
To address these challenges, we propose PacketMill, our latest work, where we discuss other efforts/optimizations required to improve the performance of packet processing. PacketMill's ideas are directly applied to FastClick, so it comes for free. More specifically, we develop/use a better integration of DPDK to minimize the memory footprint of the high-speed software dataplanes. Furthermore, we propose a pipeline to reduce the number of instructions required for processing packets by using new data structures directly derived from the graph of network functions and compiler optimization techniques.

Between the wild range ofapplications, the complexity and variety of the networking hardware,getting good performances while keeping the stack easily usable fromuserspace has been a long-standing challenge.
Nowadays, complex Network Interface Controllers (NICs) can be found evenon small embedded systems, bringing powerful features that were previouslyfound only in the server world closest to day to day users.
This is a good occasion to dive into the Linux Networking stack, to discoverwhat is used to make networking as fast as possible, by both using allthe features of the hardware, but also implementing some cleversoftware tricks.
In this talk, we'll cover these various techniques, ranging from simplebatch processing with NAPI, queue management with RSS, RPS, XPS and so on,flow steering and filtering with ethool and TC, to finish with the newestbig change that is XDP.
We'll dive into these various techniques and see how to configure them tosqueeze the most out of your hardware, and discover that what waspreviously in the realm of datacenters and huge computers can now alsobe appliable to embedded linux development.

Apart from the usual benefits arising from Open Source nature, OpenBMC brings in additional advantages like a.) state-of-the-art build system based on Yocto - an embedded linux distribution - which simplifies the process of building customized Linux, b.) Robust Managebility framework based on (4 pillars - REST, JSON, HTTPS, ODATAv4) RedFish, c.) Superior Modularity with D-bus IPC mechanism which is known for its well defined interfaces, d.) Ability to customize the code, e.) Support for IPMI, etc.
In this video, I will show you:
1. OpenBMC introduction 2. Yocto & Systemd concepts 3. Demo of building your first OpenBMC image in toaster environment and running it in QEMU, 4. Short-demo of OpenBMC porting to new platform using JSON files.Porting OpenBMC to new platforms becomes easy with easily customizable JSON files representing the platforms entities like baseboard, PSU, chassis, etc. i.e.) Platform entities are abstracted as JSON files, and sensors properties of each entity is represented as JSON key-value pairs. This can help any one having little or no experience in OpenBMC to easily port it to new platforms in quick time.PostgreSQL follows the SQL Standard. What's that mean? Why do we care?

Traditional diff implementations, such as GNU Diff, treat files as aflat list of lines. A tree-diff algorithm that can produce minimal andsemantically meaningful output is a surprisingly more difficult andcomplex problem. In fact, for unordered trees, the problem is NP-hard.
In this talk, I will demonstrate a very early working prototype of anS-expression diff program. The program can operate on two versions ofsome lisp source code and extract a meaningful tree-diff. The programaims to replace 'git diff' and related tools for lisp projects.

Whenever a central low-level component fails, dependent software stacks suffer under the outage. The talk presents Genode's recent breakthroughs to address this second part of the story, in particular making the system resilient against flaky device drivers.

There are several reasons for this, such as many viewing documentation as a separate product from code or a belief that people will be able to make sense of what the code is doing by reading the code.
For these and other reasons, documentation work is often done at the last minute and done by people with low motivation and minimum effort. So the quality of the output will naturally suffer. These issues can be addressed by ensuring that documentation is everyone’s responsibility and that documentation is a core part of the product created using the same development and community processes. Besides, documentation is often an entry point for new community members and is a great place for early contributions. When everyone in the community is actively engaged in documentation--e.g., reviewing documentation fixes--it can help provide a valuable onboarding experience for new community members.
In this session, the speakers will share their experience in documentation from both foundation-based open source projects and open source software companies. There will be a discussion on how community contributions for documentation can be encouraged and how community members can apply their learnings from documentation to other areas of open source communities.

Projects involve data collected with dozens of different instruments on dozens of different samples that are related to eachother in a hierarchical fashion. For each new project, researchers struggle with questions like: how should I organize my files and data? How should I name my samples? How should I keep track of the links between data and samples? Since no standard answer to these questions has been formulated, labs and individuals just improvise. The result is that most data and samples become utterly useless once the person who conducted the research leaves; no one else can find their way through the ad-hoc naming conventions and various excel sheets. This eventually translates into a lot of wasted and repeated efforts.
The biological sciences have long ago figured out solutions to these problems, and they are lab information systems (LIMS) and digital lab notebooks. In this talk I will present how I organize my research workflow in eLabFTW, a free and open source lab notebook with some LIMS capabilities. The tool was originally developed with molecular biologists in mind, but most of the tooling is useful for materials scientists. I will also talk about how I could leverage the python API for tailoring the tool to my needs, for example for printing QR-code stickers for database items.

DESCRIPTION:Every software ecosystem seems to have a package manager these days, but reusing software across these ecosystems is still a challenge. Major Linux distributions package software from a wide range of languages, but they restrict the versions you can install, and they make deep assumptions about compilers and runtime libraries to keep everything compatible. If you need a newer libc or a newer Python than the OS offers, you're often on your own. Python packaging supports native libraries, but it imposes strict rules on package builders to ensure that the binaries work in many places. Some packagers break the rules, e.g., TensorFlow binary packages (wheels) will only work on Ubuntu, frustrating users of other distributions. Containers provide some hope, but only if you stay inside their sandbox. If you your container to talk to a fast network or a GPU, you'll need to ensure binary compatibility between the container and the host OS. Is every ecosystem a walled garden or can we make it easier to bridge the gap?
This talk takes a deeper look at the Application Binary Interface (ABI) and its place at the heart of nearly every software ecosystem. We'll look at the assumptions made by modern dependency management systems about toolchains and ABI. Most tools assume that toolchains and ABI are fixed, making it hard to take a package from one ecosystem and transplant it in another. We'll talk about how we can build dependency managers that can reason better about ABI compatibility, making decisions not just about which software versions to install but also about how those software versions should be built. We'll look at the types of metadata that need to be managed to enable a more flexible software environment, and how it affects the complexity of dependency resolution. Finally, we'll look at how some of these issues are being addressed in Spack, an open source package manager for high performance computing applications, which can span multiple languages, compilers, platforms, and software stacks.

In this talk we provide a practical deep dive of the best practices, principles, patterns and techniques around production monitoring of machine learning models. We will cover standard microservice monitoring techniques applied into deployed machine learning models, as well as more advanced paradigms to monitor machine learning models through concept drift, outlier detector and explainability.
We'll dive into a hands on example, where we will train an image classification machine learning model from scratch, deploy it as a microservice in Kubernetes, and introduce advanced monitoring components as architectural patterns with hands on examples. These monitoring techniques will include AI Explainers, Outlier Detectors, Concept Drift detectors and Adversarial Detectors. We will also be understanding high level architectural patterns that abstract these complex and advanced monitoring techniques into infrastructural components that will enable for scale, introducing the standardised interfaces required for us to enable monitoring across hundreds or thousands of heterogeneous machine learning models.

Last year, support for pointers, aka access types, wasadded to SPARK. It works by enforcing an ownershippolicy somewhat similar to the one used in Rust. It ensures inparticular that there is only one owner of a given data at all time,which can be used to modify it. One of the most complex parts forverification is the notion of borrowing. It allows to transfer theownership of a part of a data-structure, but only for a limited time.Afterward ownership returns to the initial owner. In this talk, I willexplain how this can be achieved and, in particular, how we candescribe in the specification the relation between the borrower andthe borrowed object at all times.

However, Intel has addressed this issue with microcode updates.
We later discovered that there is a physical connection on the motherboard which allows us to control the voltage and conduct fault injection. In this talk, we will present a low-cost device: Voltpillager, which use this physical connection to break the guarantees provided by SGX again.

Until recent years, electroencephalography devices were too expensive and too complicated for most UX researchers, but now there are affordable consumer-grade EEG devices.
The talk covers EEG headsets produced by NeuroSky and Emotiv, as well as the open hardware OpenBCI project. Each headset has its advantages and disadvantages for UI/UX research. Specifics of data that can be acquired from each headset is reviewed, and existing open-source tools and libraries to get these data are discussed. The talk explains how we can use EEG headsets to evaluate mind concentration and relaxation, as well as rejection and arousal factors, which can be used to detect positive and negative emotions. EEG usage scenarios are discussed with examples of the FLOSS projects exposed to such UI testing.

Two distributions on nearly opposite ends of the spectrum include OpenMandriva (which uses binary packages, builds and updates each package individually, applications are part of the OS, ...) and OpenHarmony (which builds the OS from source in one go, is updated through OTA images, and treats applications as something separate, ...)
A developer involved in both projects explains how the 2 projects go about building their respective OSes, why both projects made the choices they made, how the approaches differ from a developer and user perspective, and what approach works better for what particular use case.

Prior, the XWiki team had been working distributively, building open-source software, for over 15 years. Some of us were working remotely full time. Other colleagues opted to go to the office. The majority of the team chose to blend the two, depending on their preferences and needs. Almost a year on, what seemed a temporary change feels like a permanent arrangement.
Being able to work entirely remotely has been, in many ways, a privilege. But collaborating during a pandemic is not business as usual. This talk reflects on the specific challenges we faced, the changes and tools we implemented to address them, and the ways we tried to support each other through this uncertain period. While there’s no one size fits all, we hope sharing our experience will prove useful for teams navigating similar challenges. We’re in this together.

DESCRIPTION:Even to this day, there's something utterly captivating about bringing to life a piece of software effectively frozen in time, designed to run on what was originally a black box, by means of a device that one uses to check up on cat facts. Adding to this, it can even be enhanced and possibly perform better than its developers ever hoped for.
If you also got to play around with your first computer in the early 2000s, chances are that console emulators were amongst the first pieces of software you've ever run on a computer. Submitting this talk was an endeavour to explore this unexplainable (or is it?) fascination by what seems to conceptually be a compatibility layer. More importantly, the talk aims to have you intrigued about emulation development and the scene in general in the year 2021, by presenting the significance of the emulation community in the context of education and history preservation.
It will also highlight how emulation development is more accessible today compared to the early days of the likes of PSEmu Pro, Project64 and NO$GMB - thanks, in no small part, to the FOSS community.
TLDR: this will focus on the "why" (rather than on the "how") you should have a go at writing your first emulator.

This is an invaluable tools to inspect and to better understand the structure of UNO objects, which is particularly useful for writing macros or extensions.The problem is that the existing object inspector tools are not so simple to use, because of their nature as an extension and in addition the user has to search and install it in addition to LibreOffice. For this reasons TDF has offered a tender to implement a build-in tool, that can be more integrated into LibreOffice and is always available to the user.The tender has been awarded to Collabora and we are in the process of implementing it. In this talk we want to present the tool, what has been done so-far and how it will look like when finished.

We will go over the different obstacles that Raphaël and his colleagues atOctobus faced during the rewrite of the ubiquitous hg status, and thesolutions they came up with to make this command (and others) a lot faster.For example, running hg status in a Mozilla working copy moved from 1.1s to0.04s, a ×25 improvement.
Themes covered include:
- Rust and Python interoperability- Fast (and slow) Rust datastructures- Fast directory traversal- Version control internals- Append-only binary formats- Mtime caching- Safe mmap usage in a concurrent context- Multithreading- Unix vs MacOS vs Windows issuesContainer registries are becoming an important source of software distribution.Why package content in a container image?A container image includes an assorted collection of software - often hundreds of software components. This format facilitates use of the software, because a complete set of the needed components are delivered as a single unit.
In this talk we look into how to ship content regardless of how it is packaged (rpm, python, ansible roles) in a container image and build the image with just one single tool - Pulp3.With Pulp3 you will be able to take advantage of software distribution using the container first strategy :
In this interview/conversation, acclaimed emulator programmer Randal Linden takes us on a journey down the depths of reverse engineering and emulator development.

Larrabee or more specifically Nyuzi showed that a software-only "Traditional Vector Processor" architecture makes for a fantastic High Performance Compute Engine that, unfortunately, also turns out to have only 25% the performance/watt of current competitive embedded mobile GPUs. Not only that but SIMD, despite being (seductively) easy to implement by hardware engineers, has been shown to have harmful consequences at the software level (setup and loop end cleanup). A recent patch to glibc6 to add POWER9 VSX strncpy was a whopping 250 hand-crafted assembly instructions, where its equivalent using Cray Vector principles is around 14.
All of this was solved decades ago by Cray Vector designs, and then forgotten. Only now is variable-length Vectorisation being rediscovered and deployed in modern architectures: RISC-V RVV, ARM SVE2 and also Simple-V. This talk therefore goes through the background and concepts behind Simple-V. Thanks to a grant from NLnet, SV will be formally documented and proposed formally as an extension to OpenPOWER, for review by the OpenPOWER Foundation.

DESCRIPTION:WebRTC was the technology everyone wanted to learn in 2020. With COVID and WFH new developers and companies came pouring into the scene. They had lots of problems making their vision happen. Many of them didn't even know what WebRTC was. When they figured that out they still had to make the long journey of figuring out how to build. This talk is my reflection of helping developerswith Pion WebRTC. WebRTC has so much potential. We just need to solve some technical, educational and cultural problems.
Out of those experiences we started WebRTC for the Curious and tried to make Pion easier to use. I also have some future ideas that I would love help from the RTC community.

One can search for keywords, Journal of Economic Literature codes, and geographical origin of data. It informs about 670 replications, that is studies reanalyzing previously published results, as well as corrections and retractions.The wiki helps researchers to compare their results to those of previous studies. It is a resource that helps to identify useful teaching examples for statistical methods, replication and studies of social science. It allows advanced students and practicing researchers to find guidance on how to publish their replication research in various journals. A collection of teaching resources, useful tools, and literature helps instructors to integrate replication into their teaching and students to integrate open science practices into their own research. With the ongoing expansion of the wiki, currently covering more than 4,500 empirical studies, it is becoming an ever more powerful tool for social science research and education.

Execution efficiency has beenfacilitated by the introduction of specialized compute elements (eg. GPUs), inorder to accelerate specific parts of tasks/workloads (such is imageprocessing). At the same time, too abstract deployment andmanagement burdens, service providers use virtualization and containertechnologies. Eliminating the software overheads of these abstractions,especially in the context of hardware off-load/acceleration is a challenge andrequires a number of factors to be taken into consideration: (a) portability,(b) performance, and (c) security.
In this talk, we attack the first two factors and examine the option ofunikernels and their surrounding ecosystem (application porting frameworks,orchestration frameworks, lightweight virtualization backends) in the contextof hardware acceleration.
We present our efforts in porting a novel hardware acceleration framework,vAccel, to the rumprun unikernel, digging into the internals of semanticabstraction for ML inference, as well as its implementation on rumprun andQEMU/KVM. We describe the frontend/backend driver port, the runtime needed tosupport the actual execution on the hardware and showcase our results in abrief demo of two unikernel frameworks performing ML inference on images.

DESCRIPTION:With Kubernetes gaining popularity for performance-critical workloads such as 5G, Edge, IoT, Telco, and AI/ML, it is becoming increasingly important to meet stringent networking and resource management requirements of these use cases. Performance-critical workloads like these require topology information in order to use co-located CPU cores and devices. Despite the success of Topology Manager, aligning topology of requested resources, the current native scheduler does not select a node based on it. It's time to solve this problem!We will introduce the audience to hardware topology, the current state of Topology Manager, gaps in the current scheduling process, and prior out-of-tree solutions. We'll explain the workarounds available right now: custom schedulers, creating scheduling extensions, using node selectors, or manually assigning resources semi-automatically. All these methods have their drawbacks.Finally, we will explain how we plan to improve the native scheduler to work with Topology Manager. Attendees will learn both current workarounds, and the future of topology aware scheduling in Kubernetes.

Result: a highly privacy-respecting, in theory secure, yet very slow, personal bank. Meet diva.exchange - the first non-profit, non-corporate, very-small-tech and research-driven association developing "Free Banking Technology - For Everyone". All licensed under AGPLv3+.
The presentation is about the technology stack of the truly distributed free banking technology "DIVA". It's also about the fact that "distributed technology" does not offer anything like a "business model" in the old-fashioned-cloudy way. It's about the overlay network "I2P". It's about the distributed storage engine "Iroha" and the challenges with a very slow network. It's about banking business logic, the user interface and its challenges being fully distributed. And it's about the research co-operations in Switzerland.
DIVA is small and local tech for everyone.

Our big project is a Bitcoin Design Guide to help both designers and developers create better Bitcoin experiences faster. We also work to promote the idea of open design, to bring more designers into the space, and to help open-source projects adopt better design processes. This presentation will provide an overview of all these efforts, where we are (early) and what the future might hold.

Languages following this pattern are an excellent fit for the sort of large software companies that typically sponsor their development. However, they are not necessarily a good fit for typical free/open-source software projects, which face different challenges and constraints. If a language were designed from the ground up to fit the free-software usecase, what would it look like? What values would it maximize, what tradeoffs would it be willing to make, and what would it be like to program in every day?

No? Well I have!
But it's not possible, right? A Go WebAssembly binary can run in browsers, but cannot serve HTTP... Or could it?
Could we run a Go WebAssembly binary into a browser's ServiceWorker, and serve HTTP from it? Well let's find out!

You will build your own toolchain, bootloader and kernel, that you will run on system with the new Risc-V open Instruction Set Architecture emulated by QEMU. You will also build a minimal root filesystem by yourself thanks to the BusyBox project. You will finish by controlling the system through a tiny webserver. The approach will be to provide only the files that are strictly necessary. That's all the interest of embedded Linux: you can really control and understand everything that runs on your system, and see how simple the system can be. That's much easier than trying to understand how a GNU/Linux system works from a distribution as complex as Debian!
You will also get details about what's specific to the Risc-V architecture, in particular about the various stages of the boot process. At the end of the presentation, you will leave with all the hardware (!), source code build instructions and demo binaries to reproduce everything by yourself at home, and add your own improvements. Most of the details should also be useful to people using other hardware architectures (in particular arm and arm64).

To keep it simple, it's usually explained that Python will automatically pass the current instance as the first argument to the method: "self" will refer to the instance the method was called on. This high-level explanation really helps with keeping the focus on learning the basics of classes, but it also side-steps what is really going on: It makes it sound like process of inserting "self" is something automagical that the language just does for you. In reality, the mechanism behind inserting self isn't magical at all and it's something you can very much play with yourself.
In this intermediate level talk, Sebastiaan Zeeff will take you down into the heart of the Python data model to explain how the mechanism behind inserting "self" works. He will talk about the descriptor protocol and how it allows you to modify how attributes are accessed, assigned, or deleted in Python. He hopes that understanding how descriptors work will demystify "self" in Python.

However, not all platforms implement UEFI, including IBM's Power machines.
In this talk, I will talk about my team's ongoing work on secure boot of virtual machines on Power. This is an important use case, as many Power machines ship with a firmware hypervisor, and all user workloads run as virtual machines or "Logical Partitions" (LPARs).
Linux Virtual Machines on Power boot via an OpenFirmware (IEEE1275) implementation which is loaded by the hypervisor. The OpenFirmware implementation then loads grub from disk, and grub then loads Linux. To secure this, we propose to:
Teach grub how to verify Linux-module-style "appended signatures". Distro kernels for Power are already signed with these signatures for use with the OpenPower 'host' secure boot scheme.
Sign grub itself with an appended signature, allowing firmware to verify grub.
Pulp helps you fetch, upload, organize, and distribute software packages.
With Pulp 2 approaching EOL and Pulp 3 being more stable than before, we strongly encourage you to move to Pulp 3. It might be a big deal if you have a large setup and a lot of carefully curated content and repositories.
To make it easy for you, we'd like to introduce a plugin which allows you to migrate from Pulp 2 to Pulp 3 smoothly and without recreating everything from scratch.

Recently it even has been accepted as ISO standard. However, compliance in todays world is not possible without tool support. To get a grip on the different tools, understand what they can do and where their limitations are, the OC tooling workgroup decided to develop a capability model. This model outlines all required capabilities to cope with the open source challenge and allows to map the functionality of tools. Thus the model can be seen as a map through the djungle of tools.In this talk, Jan will introduce the model as well as briefly outline the most relevant capabilities. Links to further resources as well as first maps will be provided.

Leaving fashions aside, some other technologies may actually be a better solution for some use cases and projects. Kubernetes is actually a very complex technology, with limited support for multi-tenancy and lacking secure isolation between tenants. Kubernetes does not offer cloud-like self-service provision features for users either. Cloud providers and cloud management tools try to bridge these gaps by offering managed Kubernetes-as-a-Service platforms, adding an extra control layer that ends up increasing management complexity, resource consumption and associated costs.
OpenNebula brings exciting new features to the container orchestration ecosystem. OpenNebula’s recent integration with Docker Hub provides users with immediate access to official Docker images. Now they can be easily imported into an OpenNebula cloud and orchestrated as a KVM-based virtual machine, as a LXD system container or even as a Firecracker micro-VM. With its native support for multi-tenancy, self-service provision and secure isolation between tenants, OpenNebula has become a simpler alternative to Kubernetes to easily set up multi-tenant Containers-as-a-Service on private, hybrid and edge cloud environments.
In this talk we will show a live demo on how to automatically deploy a Containers-as-a-Service on the edge to orchestrate multi-container applications using OpenNebula’s recent integration with the Docker Hub marketplace.

Have your cake and eat it too! DESCRIPTION:RETURNING retrieves the modified, inserted or deleted values of columns. Without RETURNING, there would be a need to run an extra SELECT query.So, along with many other benefits like triggering actions in your application based on what really gets modified, it helps to avoid a round trip and still gets the same job done! Number of queries running can be important for performance of your application as well. So you can have your cake and eat it too!

The main idea is to prevent the untrusted code from runningon our platform. The general approach is similar across vendors, but there isno standardization in this area.
During this talk we will review the Secure Boot features in ARM SoCs from someof the most popular vendors. Not only will we analyze the Secure Boot presenceor its features, but we will also focus on the tools and documentationavailability. It is a known fact that often such documentation requires asigned NDA with an SoC vendor, which makes it difficult to use by regularusers.

DESCRIPTION:In this talk we give an update on the Unikraft Linux Foundation open source project, a fully modular and librarized unikernel that aims to provide outstanding performance while making it easy to port off-the-shelf applications into unikernels. In particular, we will go into details how Unikraft (1) fully modularizes OS primitives so that it is easy to customize the unikernel and include only relevant components, (2) exposes a set of composable, performance-oriented APIs in order to make it easy for developers to obtain high performance and (3) aims for POSIX compatibility, already supporting over 130+ syscalls. In addition, there are ongoing efforts to integrate Unikraft into popular frameworks such as Kubernetes and Prometheus in order to finally bring the promise of unikernels to the mainstream. Our recent evaluation using off-the-shelf popular applications such as Nginx, SQLite, and Redis shows that running such applications on Unikraft results in a 30%-50% performance improvement compared to Linux guests. Unikraft images for these apps are around 1MB, require less than 10MB of RAM to run, and boot in around 1ms on top of the VMM time (total boot time 2ms-70ms). During the talk we will show a brief demo. Unikraft is Xen Project incubator project.

Here's one way to perform this change, in as unobtrusive a manner as possible while your table keeps serving users, by avoiding long DDL table locks and leveraging procedural transaction control.
GitOps looks straightforward from the outset, but early implementations showed that piecing together your GitOps workflow involves many decisions - big and small - adding up to a lot of work.

This model, LGPL and a proprietary commercial license today, has served the project well for more than 25 years. It is less well known that the dual-licensing model is supported by a community contract which guarantees the freedom of Qt beyond what is in the license covered. This contract is maintained by the KDE Free Qt Foundation and has kept Qt free through multiple acquisitions and other turbulences.
This presentation will explain the community contract, how it augments the dual-licensing model, and how it has evolved and served its purpose for 25 years and counting. It will also discuss what are the lessons learned and how it can serve as a model for projects today.

This next generation virtualization technology was launched by AWS in late 2018 and is designed for secure multi-tenant container-based services. This integration provides an innovative solution to the classic dilemma between using containers—lighter but with weaker security—or Virtual Machines—with strong security but high overhead.
Firecracker is an open source technology that makes use of KVM to launch lightweight Virtual Machines—called micro-VMs—for enhanced security, workload isolation, and resource efficiency. It is widely used by AWS as part of their Fargate and Lambda services. Firecracker opens up a whole new world of possibilities as the foundation for serverless offerings that need to deploy containerized critical applications nearly instantly while keeping them in isolation.
OpenNebula is a simple, yet robust, open source platform for building Enterprise Clouds and managing Data Center virtualization. Its integration with public cloud providers offers additional flexibility in creating True Hybrid and Edge infrastructures. By incorporating Firecracker, OpenNebula now provides users with a powerful solution for serverless computing and an alternative, native model for secure container orchestration.
In this talk we will explain the technical details of this integration and will show a live demo on how to easily deploy and orchestrate a composition of Docker Hub images running as Firecracker microVMs on a distributed bare-metal Edge infrastructure.

An introduction to Object Storage for Kubernetes DESCRIPTION:Kubernetes graduated Container Storage Interface (CSI) to GA status in v1.13. Since CSI’s origin, it has evolved to support a large number of vendors and storage formats. It has brought the industry together in consensus about the best practices in storage. However, CSI’s major limitation is that it only supports Block and File storage. The rapid growth of Object storage means that a growing share of the ecosystem is currently using ad-hoc solutions to leverage this new technology.Object storage is a fundamentally different paradigm where data is accessed over the network rather than locally. It allows applications to remain stateless while offloading state into a black box over the network. Object storage is the key enabler for cloud migration. This paradigm, however, does not have a standard mechanism for consumption in Kubernetes. COSI fundamentally exists to enable the natural consumption of object storage with Kubernetes.

Right now all the known quantum computers are owned by major players. The lack of availability of quantum computers makes it beneficial to centralize the power of quantum computers, using a SaaS model to democratize access to them, therefore making the cloud a suitable home for quantum computing.
The first part of the session introduces an open-source co-processor model where classical computers can offload specialized tasks that are better suited to quantum computers thus lowering the onramp to incorporating quantum computing into applications today.
The next part of the sessions demonstrate how to build a co-processor model on the cloud using two community operators that provide quantum acceleration by leveraging Qiskit, an open-source SDK for developing quantum circuits, classical components powered by Red Hat OpenShift and IBM Quantum Experience as the quantum backend
The session concludes with a small demonstration of how to run a quantum circuit on the cloud using the co-processor model.

The time has come for Kuma — the platform that powered MDN Web Docs — to evolve. For quite some time now, the MDN developer team has been planning a radical platform change. That change has now landed. In short, we have moved away from our wiki model where the content was stored in a centralized SQL database, to a decentralized pull request model via Github. Our tech stack has also radically changed, paving the way for faster future development, ease of maintenance, and opening up the platform for contribution from our community. During this talk, I will share the history of the project, talk about our recent achievements, demonstrate how to contribute to both the MDN Web Docs content and the underlying platform, and take a peek at what the future looks like for MDN Web Docs.

DESCRIPTION:Have you heard of TDD? Are you interested or familiar with this practice but have never been able to understand it?
In this session I'd like to present the benefits of Test-Driven Development (TDD), explaing how it works and what the benefits are of using it. We will see in a more detailed approach this way of developing software, where our software is always built guided by tests.
We will go over some history about TDD, which is the main process we must follow when we work with this mechanic and the rules that surround it. We will also list the main advantages and disadvantages that most developers who practice TDD find and whether the arguments in favour add up to more than those that subtract. Finally, we will review some good habits and practices when applying TDD and see how to do it step by step with a Java code example.
At the end of the session, I hope attendees will have a wider understanding of what TDD is, what advantages it brings, why it is interesting to master it and also that you will take with you some tricks and good practices to be able to apply them in your day-to-day life when writing code 😉

DESCRIPTION:The lack of accessible quality healthcare is one of the biggest problems in Africa and other developing countries. This is not only due to the unavailability of resources, but also to the absence of a structured formative process for the design and management of healthcare facilities. This situation strongly contributes to deepening inequalities in access to quality healthcare.Through an Open Society Foundations funded project, the Mboalab aims to remedy these inequalities by building Open-Source devices for medical labs. Local manufacturing can address the infrastructural barriers that prevent imported or donated equipment from being properly used, and can facilitate the diffusion of innovation into healthcare practice. This project is part of the large MboaLab mission to contribute to the Common good and catalyze sustainable local development through Open Science.

The world of EDA file formats is divided by vendors, with low flexibility to move from one program to another one. The design is for a proprietary program? Well you need to either buy the program, or hope to convert it to your favorite file-format using an error-prone conversation process. Not ideal, but better than nothing.
This talk will show you the basics to write an importer yourself, with focus on reverse-engineering of the questionable file-format. Thus, going from seemingly arbitrary zeros and ones to the basic file structure and the actual data such as a track. While this is quite easy for text-based files such as the KiCad file format, binary files can be seen more like a puzzle to solve.

However, there are not many available GIS tools that can compute this watershed parameter. At the same time, there have been almost little to no efforts in improving its computational efficiency since its first, to the presenter's best knowledge, introduction by Smith (1995) when the geospatial data resolution was relatively coarser. In this talk, the presenter introduces a new algorithm that applies Hack's law to the discovery of the longest flow path and its efficient implementation as a GRASS module called r.accumulate. He compares its performance to that of commercial ArcHydro's Longest Flow Path tool. Lastly, he introduces a proof-of-concept version of the Web-based Hydrologic Modeling System (WHydroMod) built using GRASS, PyWPS, MapServer, and OpenLayers, and discusses how r.accumulate can be used to improve the efficiency of geospatial computation for WHydroMod.

Traditionally it was an area of responsibility of three different roles: Development, DBA, and System Administrators. Now DevOps handle these all. But there is a gap. Knowledge, gained by MySQL DBAs after years or focus on a single product is hard to gain when you focus on more than one. This is why Sveta Smirnova (Percona, Support Team) is doing this session. She will show minimal, but the most effective, set of options that will improve your MySQL performance. For illustrations, she will use real user stories from her Support experience.

If the system depends on Linux, it is important to understand Linux within that system context and how Linux is used in that system. The challenge is selecting Linux components and features that can be evaluated for safety and identifying gaps that exist where more work is needed to evaluate safety sufficiently.
The ELISA project has taken on the challenge to make it easier for companies to build and certify Linux-based safety-critical applications. This talk will be given by Shuah Khan from the Linux Foundation to give an overview of the ELISA project and its technical strategy.

This narrow definition is concerned only with the shape of business contracts designed to de-risk corporate involvement in FLOSS. But we all know that what makes open source amazing is not the licensing, but the community. Open source is defined in practice by its community-driven, collaborative mode of software development. So it should be no surprise that the best open source projects have a laser focus on building thriving communities. Nor should it surprise us that many projects using OSI-approved licenses appear open source in name only. Ethics is the study of how to get along with others. This makes it the perfect tool for understanding how to build thriving, successful communities. In this talk, I argue that the Ethical Source Definition actually provides a more compelling definition of "open source" than the OSD. It better accords with community usage of the term, capturing what makes open source unique and successful.

GitOps & Chaos Engineering are at the forefront of this new CD approach, with an ever-increasing pattern involving Git-backed pipeline definitions that implement “chaos stages” in pre-prod environments to gauge service-level objective (SLO) compliance.In this talk, Juergen Etzlstorfer (maintainer of Keptn CNCF project) will discuss how you can construct pipelines that include chaos experimentation (using LitmusChaos) while simulating real-world load, and implement quality gates (based on SLOs) to ensure only resilient applications are deployed into production. He will also demonstrate how you can include chaos tests to your existing CD pipelines without the need of rewriting them.

Though there have been many projects over the years to address some of these goals, many aspects are challenging to do in the current GNU Radio runtime.
One year ago, several of us got together at the pre-FOSDEM hackfest and started planning how to "write a GNU Radio runtime that works for humans". Since that time the project has taken several different directions, all aiming to make the core aspects of GNU Radio modular and easier to use by laying a fresh foundation. In this talk, we will overview the current state of the "newsched" project, and where we plan to take it.

As applications become more complex and more distributed, they may span multiple Kubernetes clusters, or a combination of Kubernetes and on-premise workloads. While internal traffic within a Kubernetes cluster is handled by the CNI plugin, the external traffic between these workloads, or from workloads to end users, is often carried over a Software Defined Wide Area Network (SD-WAN), which is used for traffic optimization. The Cloud Native SD-WAN (CN-WAN) open source project was created to help SD-WAN deployments to identify Kubernetes applications and optimize traffic based on application requirements, thereby bridging together the DevOps from Kubernetes' cloud native world with the NetOps from the SD-WAN world.
CN-WAN enables developers to annotate their applications, specifying the type of network traffic generated by the Kubernetes workload, and this information is then published into a service registry. The NetOps configuring the SD-WAN can take these annotations and develop network optimization policies with the clear knowlegde of the traffic type they intend to optimize.
Join us for this presentation, where we will describe the components of the solution, the interfaces between the components, and how you can adapt this solution to different SD-WAN products and service registries.

Over the history of Linux, a number of system calls APIs have been introduced to improve upon the performance, features, and interface design. Developers may ask themselves which API they should use and how they differ.
This talk covers select(2), poll(2), epoll(7), as well as the more recent Linux AIO and io_uring APIs. We will look at the classic scalability challenges with these APIs as well as the latest shared kernel memory ring and polling approaches. An understanding of the evolution of file descriptor monitoring in Linux exposes API design topics that have relevance even if you don't need to implement an event loop in your application.

However, prior enclave systems are far from the ideal for three reasons.1) Scalability: only support limited secure memory or limited number of instances;2) Performance: not well-fit the requirements of high-performance application, e.g., poor secure communication performance;3) Security: many still have security flaws, e.g., suffering cache-based side channels attacks.
Penglai-Enclave is proposed to overcome these challenges. The Penglai open-source project aims to build a scalable and efficient TEE system based on RISC-V, which is made powerful through hardware-assisted scalable physical memory isolation extensions. Our evaluations show that Penglai can achieve more than 1,000 concurrently running instances even in a resource-restricted device. We also have supported libraries like ARM PSA on Penglai to ease the development of trusted applications, and applied formal methods to validate its software TCB.

Jupyter notebooks have become a popular tool to create and share documents that contain narrative text, visualizations and live code, and the xeus-cling kernel provides support for native C/C++ code via the Cling interpreter. In this talk, we will present how we extended these technologies to support parallel programming with MPI and OpenMP, the de-facto standards in HPC.
In the context of parallel programming, the resulting environment supports rapid prototyping and e-learning equally well. We will present an overview about its capabilities, demonstrate selected use cases and resources that we developed. In addition, we incorporated support for runtime correctness checking of MPI and OpenMP parallel programs. We will explain how we added support to write out binary programs from Jupyter notebooks and how to run code under the control of existing open source correctness tools.

We use an example application Riemann problem, a common problem in fluid dynamics, as our testing ground. This example application is implemented in GenASiS, a code being developed for astrophysics simulations. While OpenMP and CUDA are supported on the Summit supercomputer, its successor, an exascale supercomputer Frontier, will support OpenMP and translate CUDA-like models via HIP. In this work, we study and describe the differences and trade-offs between these programming models in terms of efforts and performance. Our hope is to provide insights on productivity and portability issues within these programming models.

And their concerns are fully justified.
So we at ONLYOFFICE, an open-source project with the focus on advanced and secure document processing, do our best to provide a comprehensive level of security for online doc editing and collaboration.
With GDPR compliant ONLYOFFICE Docs, you get a wide range of security tools and services to protect yourself from unauthorized access, data leaks, or insider actions. Self-hosted ONLYOFFICE can be installed on your own private server, so all your data always stays ‘in-house.’ The server level of data protection is implemented, among other things, with JSON Web Token and configurable cache lifetime. Important is, that no user data is stored on the ONLYOFFICE server. Besides, there are additional security features such as restriction on copying, downloading and printing, watermarking, flexible document permissions, etc.
The same applies to the integration of ONLYOFFICE Docs with other open-source services and platforms so that users of the combined solutions also get secure document editing and co-authoring.
To make your experience even more secure, last year we implemented:
Custom filter access permission that allows hiding the data you don’t want to show before sharing your spreadsheet. In other words, users won’t be able to change the filter you’ve applied before sharing your spreadsheet and will be able to work only with the specified fields.
Storage encryption so that you can protect data at rest against breaches. If the storage encryption option is enabled, all the files stored in your ONLYOFFICE will be encrypted using the Advanced Encryption Standard, symmetric block cipher, also known as Rijndael, that encrypt data blocks of 128 bits using symmetric keys of 256 bits.
The first version of ONLYOFFICE Private Rooms, protected workplaces where every symbol you type is encrypted using the unbreakable AES-256 algorithm, even if you are co-editing documents with your teammates in real-time. Files that are created, stored and shared within a Private Room never leave the directory and cannot be copied, re-distributed, or decrypted. Document encryption and decryption is performed strictly on the user’s machine end-to-end.
Besides, we are now working on multi-functional secure forms for building any document template and secure form filling when your co-author is not permitted to see some parts of the doc.

Nevertheless, it was shown that query optimizer often fails to find a good execution plan because of incorrect cardinality estimations.The perspective approach to improve cardinality estimation quality is adaptive query optimization. In contrast with classical approaches, which rely on the precomputed histograms, it utilizes the execution statistics of the previously executed queries to refine cardinality estimations. However, the original AQO uses a modification of kNN machine learning method, which implies a number of limitations on the AQO applicability.In the current lecture we will make an introduction to the kNN-based AQO. Afterwards, we will present you our novel neural network-based AQO which can potentially overcome the limitations of the kNN-based AQO, and will demonstrate the first experimental results.

DESCRIPTION:Most of the free software projects I know do little to none research with their users. Well: the vast majority do absolutely none, and very few do a teensy little bit, most of the time with the most vocal members of their user base. Why is that? Why is free software afraid of user research?
This presentation will propose a classification of free software types based on their ideas and attitudes towards user research. The classification is really just a joke, but I hope it will help me debunk some of the misunderstandings and myths that surround user research in free software circles. I will also try to explain what user research is actually about, how it can help your free software project, and give you some advice on how to get started with it.

During this presentation we'll learn how to scale FreeSWITCH capabilities so to handle high volume / high frequency transactions by having a mid-registrar absorbing the most transactions and only bother FreeSWITCH with the bare minimum info it needs (is the user reachable, and where). Multiple parallel calls can be "forked" if the user is registered as present at various devices (eg: deskphone and smartphone app), push notifications can be sent to "wake up" the user's app. We'll use OpenSIPS as an example of mid-registrar, but the same concepts and techniques can be implemented by any open source SIP proxy, like Kamailio, Repro, etc

More database capacity? Resources for your artificial intelligence use case? Just spin-up another instance and you are good to go. While most cloud images (e.g., AMIs on Amazon EC2) are meant to run a single service (e.g., nginx), for convenience these tend to be built on top of general-purpose OSes and full distributions, often resulting in GB-sized images that sometimes only need to perform a simple task such as serving static web pages. One of the main contributing factors to this status quo is the myriad kernel inter-dependencies, rendering debloating of a Linux kernel image far from trivial. In this talk we will show results from a proof-of-concept deployment on Amazon EC2 using Unikraft, a fully modular library OS that makes it easy to remove unneeded components, and to optimize the remaining ones. On EC2, a Unikraft nginx image is able to outperform an nginx Debian image by 2x in terms of requests/sec when serving static content, all the while consuming 1/6 of the memory (we will show a brief Unikraft demo). Unikraft is an open source Xen Project incubator under the auspices of the Linux Foundation.

This talk will try to answer those questions and compress multiple decades into less than an hour - or at least give an overview of the big-picture events this project lived through. As the audience may be more familiar with recent than earlier years, more emphasis will be put on times when the project was still young - for some things even reaching back to times before the speaker joined the community in 1999. After attending this talk, you will hopefully have a better understanding of the background of the Mozilla project and how it has helped shaping the web for the better, something that will hopefully continue into the future.

At the University of Maryland I created an elective for undergraduates in the CS dept. that introduced DSP and SDR in a hands-on manner, and have since taught the course twice. During this course, students learn basic wireless communications and DSP concepts, and how to implement the techniques onto SDRs. Additional course learning objectives include digital signals, filtering, frequency domain, digital modulation, noisey channels, cellular, and IoT. The course utilizes open-source SDR toolkit software including GNU Radio and Python libraries, allowing students more interesting and engaging assignments/exercises and more advanced concepts to be explored. Every student had a PlutoSDR to use during the semester. What is unique about this course is that this material is typically taught at the graduate level within ECE, spread across numerous individual courses. CS students, at least at our university, do not get exposed to any DSP or signals background which is normally required to learn about SDR using traditional methods/textbooks, so they must start from scratch, which is why this course has heavy use of graphics, animations, and examples. As such, this course does not dive as deep into the mathematics behind the theory as a normal graduate level ECE course would. There is much more emphasis on "learning by doing", and actually creating SDR applications.
In addition to the course I have created a free online textbook called PySDR, that is based on the material I taught in my course, which anyone can use to learn DSP and SDR using Python. My textbook does not use any custom libraries or code, it's essentially showing how to use straight Python (e.g. mostly numpy, scipy, and matplotlib) to actually do DSP and create SDR applications. Through feedback I've gotten from people using this online textbook, I have learned about what it takes to teach DSP and SDR to folks in a non-university setting. The source code used to generate the textbook (using Sphinx) is hosted on GitHub, so that readers can submit issues or even PRs, to date there has been several contributors. I'm hoping this presentation can show that you don't need to be a EE with a masters degree to dive into DSP and SDR.

We present GossipSub, a gossip-based pubsub protocol, which, in contrast to past pubsub protocols, incorporates resilience against a wide spectrum of attacks.
Firstly, GossipSub's mesh construction implements an eager push model keeps the fan-out of the pubsub delivery low and balances excessive bandwidth consumption and fast message propagation throughout the mesh. Secondly, through gossip dissemination, GossipSub realises a lazy-pull model to reach nodes far-away or outside the mesh. Thirdly, through constant observation, nodes maintain a score profile for the peers they are connected to, allowing them to choose the most well-behaved nodes to include in the mesh. Finally, and most importantly, a number of tailor-made mitigation strategies designed specifically for these three components make GossipSub resilient against the most challenging Sybil-based attacks. We test GossipSub in a testbed environment involving more than 5000 VM nodes deployed on AWS and show that it stays immune to all considered attacks. GossipSub is currently being integrated as the main messaging layer protocol in the Filecoin and the Ethereum 2.0 (ETH2.0) blockchains.

Instead of building a single instance of TEE hardware, Keystone provides security primitives, which can be composed by the software framework. The enclave developer and the platform provider can customize the TEE in order to meet their threat models or platform configurations. The Keystone project aims to build an open standard for TEEs by providing a generic and formally-verified interface for a wide range of devices. We envision that every hardware can have a secure TEE with almost no additional cost. In this talk, we will discuss the current state and future directions of the project.

Working towards sustainable solutions with PubPub. DESCRIPTION:Having started on a very typical path for open source projects - needing to solve our own problems - we were struck by the challenge that our technology wouldn’t be sufficient for our eventual goal: improving the culture and process of scientific publishing. The challenge is not only technologically broad and complicated - but there are also enormous cultural and operational logistics needed to approach real solutions. Not least of which is the ability to provide resource-constrained, technologically-limited organizations with the stability and support they need to make commitments that will last years if not decades.
We’ll share our experience with PubPub and the Knowledge Futures Group (a non-profit organization dedicated to building digital infrastructure as a public utility), what it’s taught us about building sustainable open source products, and welcome contributions to make our work more supportive and inclusive of the entire knowledge community.

Fast forward more than 3 years and the Vonage API Developer is now running on a custom-built open-source tool we call Station. Station powers multiple documentation portals, and allows us to achieve numerous organizational goals.
How did we arrive at Station and not get derailed in the process?
In this talk, we will take a deep dive into the technical journey behind Station. What does the tech stack look like? How did we solve some serious technical challenges converting a Ruby on Rails website into an executable tool, and what did we learn along the way?
We haven't reached the end of the line in the evolution of Station yet, and we will discuss what stops are next in the journey. In the dialectic between being feature-rich and being overly complex and complicated, Station presents a model forward. Let's explore that model together.

The EESSI codebase (https://github.com/eessi) is open source and heavily relies on various other open-source software, including Ansible, archspec, CernVM-FS, Cluster-in-the-Cloud, EasyBuild, Gentoo Prefix, Lmod, ReFrame, Singularity, and Terraform.
The concept of the EESSI project was inspired by the Compute Canada software stack, and consists of three main layers:- a filesystem layer leveraging the established CernVM-FS technology, to globally distribute the EESSI software stack;- a compatibility layer using Gentoo Prefix, to ensure compatibility with different client operating systems (different Linux distributions, macOS, Windows Subsystem for Linux);- a software layer, hosting optimized installations of scientific software along with required dependencies, which were built for different processor architectures, and where archspec, EasyBuild and Lmod are leveraged.
We use Ansible for automating the deployment of the EESSI software stack. Terraform is used for creating cloud instances which are used for development, building software, and testing. We also employ ReFrame for testing the different layers of the EESSI project, and the provided installations of scientific software applications. Finally, we use Singularity containers for having clean software build environments and for providing easy access to our software stack, for instance on machines without a native CernVM-FS client.
In this talk, we will present how the EESSI project grew out of a need for more collaboration to tackle the challenges in the changing landscape of scientific software and HPC system architectures. The project structure will be explained in more detail, covering the motivation for the layered approach and the choice of tools, as well as the lessons learned from the work done by Compute Canada. The goals we have in mind and how we plan to achieve them going forward will be outlined.
Finally, we will demonstrate the current pilot version of the project, and give you a feeling of the potential impact.

AFXDP is a new type of socket that is optimized for high performance packet processing based on eBPF and eXpress Data Path-XDP. XDP allows you to attach an eBPF program to a lower-level hook inside the kernel (aka the NIC Driver). It offers some very promising performance increases for microservices while allowing them to adhere to cloud native design principles. There are however some challenges for deploying a microservice based on AFXDP. This talk will cover an introduction to AF_XDP, why it is suited to cloud native microservices, how it can be deployed today and the deployment challenges as well as their solutions.

There are many profiling tools that can instrument serial and parallel codes, and gather performance data. However, analytics and visualization tools that are general, easy to use, and programmable are limited. Hatchet is an open-source Python library that can read profiling output of several tools, and enables the user to perform a variety of programmatic analyses on hierarchical performance profiles. Hatchet brings the power of modern data science tools such as pandas to bear on performance analysis. In this talk, we present a set of techniques and operations that build on the pandas data analysis library to enable analysis of performance profiles. These techniques, implemented in Hatchet, enable the filtering, aggregation, and pruning of structured data. In addition, Hatchet facilitates comparing performance profiles from multiple executions to understand the differences between them.

Database vendors are moving away from traditional deployment methods and embracing database as a service (DBaaS) as the default method to offer their database technologies to consumers and users. Much of this movement has been built because of the success and popularity of DBaaS offerings by major cloud vendors. Unfortunately, this is leading to a new era of NROSS (Not really open source) technologies that pretend to be free, open, and transparent but simply are not.As people wake up from the hangover’s caused by the incompatibilities, lack of portability, and increased costs they are looking at how to reclaim the openness, transparency, and freedom true OpenSource has provided them in the past. We will explore the trends and give his opinions and ideas on how we need to disrupt the current trends to keep open source open, and give users the freedom of having a quality alternative.

This happens because the query optimizer does not realize that the queries are equivalent. In this presentation, we will discuss how we can rewrite queries to help the optimizer find a better query plan. We will show several examples of how we can transform subqueries to make them more efficient, and we will also discuss how we can identify queries that can become faster if a subquery is replaced by window functions. Finally, we will discuss how MySQL 8.0 can do some of these transformations automatically.

In many cases, it is the most suitable option for geometric data like points, boxes, etc. An easy way to increase the selection speed is to eliminate the need for the results recheck by a table. But with the index being single-column by design we could not enjoy index-only scans for multicolumn queries.
The talk covers my improvement of the SPGiST access method. Non-key columns can now be included in a single key-column index in a way, similar to that have in GiST and B-tree. This adds the ability to make fast index-only scans for multicolumn queries. Also, non-key columns with data types without SPGiST opclass can be added, which creates an opportunity for the new use cases. In my presentation, I will justify the modification, discuss new use cases of GiST and SPGiST indexes, and share some performance benchmarks.

Ever had troubles with code that "works on my machine" only? Do you consider your Research and Development smooth and straightforward? Is your code scalable? Tough questions, I know. But if you've mentally answered 'no' to any of those you could use a tool to help with some of the pain-points of your workflow. Kedro is an open-source Python library that helps data scientists write data pipelines following software engineering best practices from the start. Known as the Django of ML/DS projects, Kedro is an opinionated framework based on cookiecutter data science that allows for modularity and scalability on data science projects.
In this talk, I will explore the workflow of a Kedro project, introduce some of the most outstanding features of the framework, such as the Data Catalog and show how to convert a Jupyter Notebook into a Kedro project, allowing for scalability and team collaboration.

The project was to implement a new dependency resolver and improve pip's usability. It was a difficult project as personally, I knew very little about software package managers apart from doing "pip install". How do you do UX design with a piece of software used by hundreds of thousands (possibly millions!) of users on a small budget? Where do you find those users? Combined with this the maintainers were under pressure to do a lot of complicated work in a short period of time.
This session will be a recorded discussion between the UX designers and the pip maintainers. We'll talk about what it was like to spend a year working together, the challenges, and the lessons we can teach others. We'll leave 5 minutes (approx) at the end for Q&A.

With their standardization at the IETF almost complete and several mature implementations being deployed, we can start looking into which performance improvements they bring in practice. There's just one problem though: they're quite complex and difficult to test. Using high level tooling like lighthouse might show that they're faster or slower, but rarely why.
But problems are there to be solved, and that's what I've been doing for the past 2 years with the qlog and qvis projects. The qlog structured endpoint logging format (https://github.com/quiclog/internet-drafts) is supported by over 70% of all QUIC implementations and allows you to extract low-level protocol information in JSON directly from the client and server. These traces can then be loaded for analysis in different interactive visualizations in our open-source qvis toolsuite (https://qvis.edm.uhasselt.be). This brings an unparalleled opportunity to analyze performance problems and opportunities to the new protocols, as these tools start where the browser devtools end.
In this talk, we will explore QUIC and HTTP/3's main performance oriented features, such as 0-RTT connection establishment, advanced congestion and flow control, stream multiplexing and prioritization, and Head-of-Line blocking removal in-depth. We discuss how they are supposed to work, why it's not always that easy in practice, and of course: how to diagnose issues with these features using qlog and qvis. We will use concrete examples of bugs found in major implementations to teach how to interpret the behavior of these new protocols, based on some of our research (https://qlog.edm.uhasselt.be/epiq).
We explain how to properly approach testing the new protocols in the future, as great care should be taken in interpreting any results and their root causes. Along the way we debunk some common misconceptions on the protocols and their potential improvements (no, the fact that QUIC runs on top of UDP does not mean it no longer needs congestion control or magically becomes faster, no matter what that Hackernews commenter claims).

As such, DSSoCs can boost the performance and energy-efficiency of software-defined radio (SDR) applications without degrading their flexibility.Harvesting the full potential of DSSoCs depends critically on integrating an optimal combination of computing resources and their effective runtime utilization. For this reason, the design space exploration process requires evaluation frameworks to guide the design process. Full-system simulators, such as gem5, can perform instruction-level cycle-accurate simulation. However, this level of detail leads to long execution times and is beyond high-level design space exploration requirements. In contrast, hardware emulation using Field-Programmable Gate Array (FPGA) prototypes are substantially faster. However, they involve significantly higher development effort to implement the target SoC and applications. Given the design complexity, there is a strong need for a simulation environment that enables rapid, high-level, simultaneous exploration of scheduling algorithms and power-thermal management techniques.To this end, we present DS3, an open-source system-level domain-specific system-on-chip simulation framework that targets SDR applications. DS3 framework enables (1) run-time scheduling algorithm development, (2) dynamic thermal-power management (DTPM) policy design, and (3) rapid design space exploration. DS3 facilitates plug-and-play simulation of scheduling algorithms; it also incorporates built-in heuristics and a constraint programming-based scheduler to provide an upper bound of performance (i.e., optimal schedule for a set of applications and an SoC configuration) for users. Hence, it can be used to develop and evaluate new schedulers that can be integrated into GNU Radio. DS3 also includes power dissipation and thermal models that enable users to design and evaluate new DTPM policies. Furthermore, it features built-in dynamic voltage and frequency scaling (DVFS) governors deployed on commercial SoCs.In this talk as we discuss the DS3 capabilities, we will present a benchmark application suite with applications from wireless communications and radar processing domains including WiFi TX/RX, low-power single-carrier TX/RX, range detection, and pulse Doppler. We will conclude the talk with design-space exploration studies using these applications.

However, in the same way DevOps will involve teams that code, test and set up infraestructure, ClassOps will have to add teachers to that equation. At any rate, it will imply that teachers will need to lay down in code the requirements of a student assignment (which can be as simple as testing for inclusion of a file or as complex of setting up the infrastructure to probe the code in different ways) and set up CI pipelines to actually test, and give meaningful (and fast!) feedback to the student so that it's included in their learning experience. This (lightning) talk will explain how the speaker set up that kind in infrastructure in Travis and, lately, GitHub actions, and how that resulted as a learning experience for him and his students.

While they defy simple computation, they are computationally expensive, involving computation of perhaps millions of probabilities and weights. While these computations can be done outside of the database, there are specific advantages of doing machine learning inside the database, close to where the data is stored. This presentation explains how to do machine learning inside the Postgres database.

Buildtest (https://buildtest.readthedocs.io/) is an HPC testing framework to aid HPC facilities to perform acceptance testing for their system. HPC systems are growing in complexity, with a tightly coupled software and system stack that requires a degree of automation and continuous testing. In the past decade, two build frameworks (Spack, EasyBuild) have emerged and widely used in HPC community for automating build & installation process for scientific software. On the contrary, testing frameworks for HPC systems are limited to a few handful (ReFrame, Pavilion2, buildtest) that are in active development.
In buildtest, users will write test recipes in YAML called buildspecs that buildtest process to generate a shell script. buildtest utilizes versioned-based JSON Schema for validating buildspecs and currently, we support two main schemas (compiler, script). The script schema and compiler schema are used for writing traditional shell-scripts (bash, sh, csh), python-scripts and single source compilation test. In this talk we will present an overview of buildtest and how one can write buildspecs. Furthermore, we will discuss Cori Testsuite (https://github.com/buildtesters/buildtest-cori) in buildtest with several real examples on testing various components for Cori system at NERSC.

The fragmentation of different technical solutions makes it difficult for 3rd parties or developers to work with easily accessible vehicle APIs.
To tackle this, the GENIVI Cloud & Connected Services project is designing an end-to-end communication framework starting from the data transfer from embedded systems in the vehicles and spanning to cloud based APIs. The framework is built on open protocols and is demonstrated with open-source reference code with the aim of simplifying implementation work for both car manufacturers and 3rd party developers. This presentation will detail the work results to date and will be co-presented by Kevin Valdek from HIGH MOBILITY and Ulf Bjorkengren from Geotab.

The Asynchronous Replication Connection Failover featurecomplements this by further increasing the resilience of replicationconnections between a replica and a set of sources. It allowsasynchronous replicas to switch to a new replication source when thecurrent connection fails. Therefore, an asynchronous replica canautomatically switch-over its replication connection to a new member,when it is replicating from a Group Replication group, for instance.
In this session we will present how Asynchronous ReplicationConnection Failover feature automates the process of re-establishing areplication connection to another source, upon failure of the currentone. We will also present about how this feature integrates withGroup Replication and thus how setting it up can be automatedas well.
Come and learn more about this new and exciting replication feature inMySQL, directly from the engineers developing the product.

DESCRIPTION:Disaggregated computing today relies more on add-in-cards like FPGAs/Smart NICs/xPUs. Traditionally add-in-cards have relied on IPMI based manageability solutions. However, the newer standards from DMTF (PMCI protocol stack) provide more robust and scalable solutions for add-in card manageability.SPDM provides the attestation and secure communication channel between the BMC and the add-in cards. MCTP/PLDM stack provides mechanisms for the BMC to auto discover card’s capabilities and carry out manageability functions like sensor monitoring, event logging, firmware updates etc. This provides significant advantage over IPMI which lacked secure communications and had limitations on supporting advanced high speed interfaces like PCIe and had limitations on number of sensors it could support.
We plan to present on how add-in-cards can be managed through PMCI protocols and how do we model the add-in-cards’ manageability functions in a way a DataCentre orchestration software can consume it (i.e. Redfish modelling of add-in-cards). The implementation is planned for OpenBMC and a variety of Add-In-Cards can be supported through a standard manageability model.

Writing concurrent programs is hard. Testing the concurrent program is harder. Debugging the concurrent program is a nightmare.
The incorrect concurrent program can run for years, tricking us to believe it is stable code. And then fail spectacularly when we least expect.
Why run this risk when OpenJDK provides an amazing tool to test the correctness of your concurrent programs?
Meet JCStress. A concurrency stress test tool used by JVM developers to test the correctness of the JVM itself!
In this session, you will understand how to use JCStress and how to test your concurrent programs. You will write tests and learn how to deal with different scenarios.
Start using JCSTress on your projects today. Eliminate the risk of catastrophic concurrency failures in your Java applications. Test now so you don't have to debug it later.

And despite being a 16-bit command line operating system, DOS was actually pretty good for the era. This presentation will look back at DOS in the 1980s and 1990s, and remind us why we started FreeDOS in 1994.
We've continued working on FreeDOS since then. We released FreeDOS 1.2 in 2016, and are currently working on FreeDOS 1.3. DOS stopped being a moving target in 1995, but FreeDOS re-imagines what a "modern DOS" could look like in 2021. We'll also look at the current state of FreeDOS (FreeDOS 1.3), and what's coming up next (FreeDOS 2.0).

A few Linux distributions already have good support and have compiled most of their packages for it. The boot process has been neglected and only recently did everyone start using the widely used embedded bootloader U-Boot instead of a custom research bootloader. We have ported the EDK2 reference implementation of UEFI to make the boot process more like current desktops and servers. This talk explains how we did that, how it works and how we got Linux to boot.We also want to explain what's left to do and how we can move in the direction of a RISC-V server platform.

Think big data, storage, analytics, 5G, virtual network functions, then encrypt it all at 40Gbps line rates. Kubernetes and the Kubernetes network model are increasingly seen as essential to help manage these workloads at scale. But the cost of containerization and container networking can be hard to swallow for workloads that are often used to having dedicated NICs and physical hardware. Our novel solution was to cook up a feast that is a fusion of two worlds: combining Calico, the popular cloud native Kubernetes network plugin, with VPP, a very fast and scalable userspace packet processing software. In this talk we will lift the lid on what we’ve been cooking and the key ingredients that made it possible to offer an all you can eat buffet for your hungriest workloads.

Originally conceived for graphic designers to provide a series of tasks not available with other tools, it evolved into a platform widely used in research and data journalism contexts that provides simple ways to map data dimensions onto visual variables. It presents a chart-based approach to data visualisation: each visual model is an independent module exposing different visual variables that can be used to map data dimensions. Consequently, users can create complex data visualisations. Finally, the tool is meant to produce outputs that are open, that is, not subjected to proprietary solutions, which can be further edited.Thanks to an intuitive user interface and experience drafting visualizations become an easy task, enabling the user to produce the visualizations not only as a mere output but also as a tool within the research process.Last year we launched a successful crowdfunding campaign to raise funds for the redesign and development of a new version of RAWGraphs, that will be released in the first months of 2021.The new version is written from scratch with the aim to make the tool more flexible for customisation and to create an active community also on the development side.The talk aims at presenting how RAWGraphs has been used in research context and our strategies to keep the project free, open source, economically sustainable and independent.

In this article we will explain how our internal solution evolved from a Proof of Concept to a broader deploy in other major companies, to perform Continuous Delivery, Continuous Testing and Monitoring at scale.

This is due to the fact that a variety of celestial objects emit electromagnetic radiation at radio wavelengths, which has led to the development of radio telescopes capable of revealing the otherwise-hidden astrophysical properties of the universe. An important requirement that makes radio astronomy observations and analysis possible is an appropriate software pipeline compatible with the spectrometers with which radio observatories are equipped. In this work, we present Virgo: a versatile software solution for radio telescopes.
Virgo is an easy-to-use open-source spectrometer and radiometer based on Python and GNU Radio (GR) that is conveniently applicable to any radio telescope working with a GR-supported software-defined radio (SDR). In addition to data acquisition, Virgo also carries out automated analysis of the recorded samples, producing an averaged spectrum, a calibrated spectrum, a dynamic spectrum (waterfall), a time series (power vs time) and a total power distribution plot.
By additionally providing the observer with an important set of utilities, Virgo also makes for a great tool for planning (radio) observations. This includes the ability to compute the position of astronomical sources in the sky for a given date, estimate the right ascension and declination given the observer's coordinates along with the altitude and azimuth the telescope is pointing to and convert equatorial to galactic coordinates with the help of the open-source Astropy package.

Instead of focussing on a lack of tools or skills, I want to show that the difficulties are also rooted in different views on what makes a "good" user and a desireable mode of collaboration. Open Source projects, prototypically, focus on the developer/user who scratches an own itch and coordinates in an stigmergic, bazaar-like way, while design usually focusses on expertise in designing for others and a plan/execution model instead. While no easy fix can resolve these differences, I want to suggest some ways to ease communication for developers and designers.

We go beyond this complete framework by exploiting library-OS/unikernel idea in a container runtime. We ported containerd to macOS first (*1), which is currently under review, and run Linux applications with Linux Kernel Library (LKL), a library version of Linux kernel, which have no compatibility concerns as LKL is derived from Linux kernel. As a bonus, we benefit from the extensibility of the kernel components of Linux containers (as Kata containers does), while keeping low resource footprint of containers (as Nabla or other unikernels implementations can).
Because the containerd port is still undergoing, we aim this talk at giving a broader view the pull request, with why we've been worked on for this direction, how it internally works, what benefit we can obtain, and where we are moving forward. We will also give a simple demonstration of running Linux containers on macOS (on Intel but hopefully on arm64 if it's getting ready).

On the other hand, they give rise to a number of challenges on a) designing and implementing a suitable architecture for the needs of the target applications, b) deploying dynamic and low-overhead resource management strategies, and c) effectively enabling execution of pipelined workflows for streaming applications. Furthermore, application developers need productive tools to port their software-defined radio applications to increasingly heterogeneous SoCs. We think that application developers should not waste their time reading datasheets or APIs for SoC-specific kernel extensions just to take full advantage of their hardware. With these in mind, this talk will discuss strategies we are using to address the aforementioned inter-related challenges through our vertically integrated compile-time and run-time environment CEDR: a Compiler-integrated, Extensible, DSSoC Runtime.
CEDR is an open-source ecosystem that runs in Linux user-space and enables compilation and development of user applications, resource management strategies, and accelerator integration in one unified framework. CEDR supports highly recurring, stream-based application graphs through pipelined execution and processing element based work queues. CEDR is built on a thread-per-PE scheduling methodology, enables integration of complex resource management heuristics that rely on work queues and require reservation-based policies. CEDR supports contemporary scheduling algorithms built on imitation learning (IL) that uses complex schedulers offline to construct an Oracle and effortlessly replicates those decisions online using machine learning models such as regression trees and neural networks. We will demonstrate CEDR deployed on the Zynq UltraScale MPSoC by conducting execution time, throughput, resource utilization analysis through dynamically arriving workload scenarios composed of Radar and WiFi applications. We will demonstrate the distinct plug-and-play integration points offered by CEDR for application engineers and hardware architects through case studies that illustrate our ability to rapidly evaluate various configurations of applications, schedulers, and accelerator IPs.

For this same reason, there are mechanisms that support us to make that possible. Surely callbacks were a thing in the past, however, they were an antipattern themselves due to the lack of readability. Now we don't need to deal with them any more thanks to Kotlin Coroutines.Getting ready for Declarative UIs with Kotlin Coroutines and friends is indeed feasible, now we could use suspend functions, Flow and in the end StateFlow would make our Reactive apps ready for Declarative UIs.Let’s define a single entry point, receive data, transform it into a state, and render each state. Let’s get our apps ready for a Declarative UI world on Android.

• Because development environments are configured separately from CI (and are often pared down and simplified), devs run into hard-to-predict CI errors caused by discrepancies in environments.
• Integration and end-to-end tests are commonly available only in CI, meaning that troubleshooting these test failures requires long and inefficient feedback loops—every fix requires a developer to push and wait for another CI run.
In this talk, we will describe and demonstrate how to use the open source project Garden to ensure that environments are consistent and predictable at every step of the pre-production pipeline—from development, to testing, to CI. We’ll also show how to give developers the ability to run integration and end-to-end tests during the development process, making it easier to catch and fix issues when it’s most efficient.

It leverages merkle-linked graphs in order to parallelize retrieval and verify content integrity. Bitswap is being used in the InterPlanetary File System architecture as the main content exchange protocol, as well as in the Filecoin network as part of the block synchronisation protocol. In this work, we present Bitswap’s baseline design and then apply several new extensions with the goal of improving Bitswap’s efficiency and efficacy and minimizing its bandwidth fingerprint. Most importantly, our extensions result in a substantial increase to the protocol’s content discovery rate. This is achieved by using the wealth of information that the protocol acquires from the content routing subsystem to make smarter decisions on where to fetch the content from.
This talk is focused on sharing the operation of Bitswap, the testbed we build to test improvements of Bitswap, and the ways in which we improved Bitswap building the foundation for research lines on file-sharing in P2P networks.

The overarching design goal is to provide a fluent API that enables the user to express the design in a natural way. CQ is based on the open source CAD kernel from OpenCascade [2] and therefore offers industry standard B-Rep modeling capabilities and allows exporting to STEP and many other formats.
With the upcoming 2.1 release [3] there many improvements coming to CQ. I will briefly summarize them but will focus on the new assembly system. The new CQ version allows the user to combine individual CQ objects into an assembly with the possibility of nesting. The individual object positions can be specified manually in terms of constraints that are solved using a numerical solver. Once an assembly is defined and all the positions specified it can be exported to STEP preserving the assembly structure or an internal OpenCascade XML format. In the I will discuss the current assembly system design, capabilities, limitations and possible future development directions.

Many people might be switching open source communities these days stepping in their new roles. The pandemic might bring you to where you would never expected to be. What if you need to start working for a competing vendor and become an advocate of a totally different technology ecosystem?
“Just do it” would answer many of your questions, but not all of them. Ethical issues related to integrity, practical failures related to lack of knowledge, the inability to use background info accumulated previously would become factors preventing you from success.
In our talk, we will combine practical advice from a community manager who moved from MySQL to PostgreSQL environment, with recent findings from academic research in community management. We’ll talk about practical techniques to transform a good community professional into a person of high trust. We will discuss ways to build your community not only around vendors, projects or technologies, but also around yourself, as an inspiring community professional. Finally, we’ll speak about scientifically based ways of building trust in a new community, and leveraging the old ties in the ethical and constructive way.

However, testing these extensions is rather tricky in practice. Often extensions require external resources which have to be injected into the development environment. Unit tests are quite bad at testing the UI itself, as they require extensive setup code and a lot of mocking (= implementation of the production API in the testing environment that exposes the same interface). Checking the results of them still requires one to manually verify that the UI looks correct. All this combined can easily lead to false-positives and false-negatives. Integration tests on the other hand are not a silver bullet either as they can be rather brittle, slow, lengthy to write, hard to set up while also not being able to cover edge-cases very efficiently.This talk will focus on what we learned while developing the Open Build Service Connector: which testing strategies work, which don't and what tools to use. We will cover some viable approaches to unit testing and the vscode-extension-tester module that we used for integration tests.

From the humble generic GNU Make to large scale platforms like Apache Airflow you would think that there is something there to satisfy everyone. All of these systems have one thing in common: they have a strong focus on partitioning large computations and scheduling work units, but when it comes to managing the software environments that are the context of each of the planned computations, they are often remarkably shy to offer opinionated solutions.
Software management and deployment often seems like an afterthought. Workflow language designers increasingly seem to be following the devops trend of resorting to opaque application bundles to satisfy application and library needs. While this strategy has some advantages it also comes with downsides that rarely seem to be weighed carefully.
We present the Guix Workflow Language --- not as a solution to the question of software deployment in HPC workflows, but as an instance of convergent evolution: growing a workflow language out of a generic reproducible software management and deployment system (GNU Guix) instead of sprucing up a workflow language with software deployment features. We hope to encourage a discussion about the current state of workflow languages in HPC: when it comes to software and distributed computations, are we approaching the peak or do we circle a local maximum?

However, portable, efficient and easy-to-use scheduling of these workflows is still an unsolved problem. In this talk, we present Flux, a next-generation RJMS designed specifically to address the key scheduling challenges of modern workflows in a scalable, easy-to-use, and portable manner. At the heart of Flux lies its ability to be seamlessly nested within batch allocations created by itself as well as other system schedulers (e.g., SLURM, MOAB, LSF, etc), serving the target workflows as their “personal RJMS instances”. In particular, Flux’s consistent and rich set of well-defined APIs portably and efficiently support those workflows that can feature non-traditional patterns such as complex co-scheduling, massive ensembles of small jobs and coordination among jobs in an ensemble.
We will also cover how the Flux-Framework project is structured around open-source development, including our use of the Collective Code Construction Contract (C4), RFCs, LGPL, and various online open-source platforms. We discuss how these choices of open-source processes have influenced the repo structure, the code, our collaborations, and even the sub-teams within the project.

SPDM’s vision is to resolve the long-lasting problem of compatible secure communication solution between two endpoints of embedded systems. Protocols defined by SPDM can be used for a wide range of security functionalities including authentication of hardware/firmware identities, delivering measurements, performing attestation, and establishing session keys for secure communication channels.
This presentation introduces OpenSPDM, an open-source sample implementation which implements an SPDM requester utility to validate a vendor’s responder implementation. The talk covers SPDM 1.0 device authentication and firmware measurement collection, and SPDM 1.1 session creation for data communication protection.
The audience will learn the main components of the SPDM protocol. A firmware solution builder will learn how to implement a SPDM requester to perform device authentication/attestation and create a secured session with a target device. A device builder will learn how to implement a SPDM responder for authentication/measurement requests and create a secured session to protect communications.

This simplification of cloud programming appears ideal (in theory) but the catch is that when someone needs to perform a more complex task, things could get a bit more complicated.
Hardware acceleration, for instance, has been a pain point, even for traditional cloud computing programming models: IaaS providers chose dedicated solutions to avoid interference and preserve tenant isolation (device passthrough), while losing one of the most important benefits of virtualization, flexibility in workload placement through live migration. Various solutions have been proposed to overcome this limitation (API remoting, hardware slicing etc.). In the Serverless world though, do we need users to interface with a hardware device directly?
Most serverless deployments are backed by containers, however, the most popular (and used) one, AWS Lambda, uses a ligthweight VMM (AWS Firecracker) integrated in the container ecosystem, in order to ensure strict isolation, while maintaining scalability. To this end, enabling hardware acceleration on this kind of deployment incurs the same pain points with traditional cloud infrastructure.
Kata containers evolved from clear containers and offer hypervisor support for popular orchestrators container deployments such as docker, Kubernetes etc. Through kata containers, AWS Firecracker VMs can be easily provisioned as Pods on a kubernetes system, serving workloads prepared as container images. We build on the kata container runtime and port the necessary components to support vAccel, a lightweight framework for hardware acceleration on VMs, on Firecracker.
In this talk, we briefly go through vAccel, its design principles and implementation, while focusing on the integration with kata-containers and the end-to-end system applicability on ML inference workloads. We present a short patch for kata-containers to support AWS Firecracker v0.23.1, and go through the necessary patching to add the vAccel framework on k8s. Finally, we present a short demo that scales image classification purpose-built microVMs across a working K8s cluster with GPUs.
Hardware acceleration for serverless deployments has never been more secure!

Using QEMU for liberating driver developers from being bound to hardware schedules isn't new. Not so common however, is adding support for new hardware to QEMU while the spec is still being revised. The coupling of driver development and emulation development helped find spec issues early, and allowed us to submit patches for a basic driver on the day that the specification wasreleased.
This talk will discuss how we used QEMU to meet our goals, the challenges in enabling CXL 2.0 for QEMU, an review of what CXL is, an overview of the architecture and implementation, and ways in which we'd love to get help.

This results in the language and its core classes behaving in a way that it is surprising — particularly to those coming from other languages — but also intuitive. The philosophy also carries over to those who develop modules as well, particularly as certain features in Raku allow for modules to integrate themselves deeply (and often transparently) into the language.

Each issue serves as a collective lab, where we test and validate novel approaches to content production, distribution, and monetization, with a unique cohort of contributors every quarter. Through subsequent issues of COMPOST, our learnings and code will be published to the commons as Distributed Press. Along with inspiring creators and readers with our magazine, our objective is to develop better open-source tools for decentralized publishing to catalyze an interdependent ecology of publishing projects.
In our talk, we will present the organizational and technical scaffolding of COMPOST and Distributed Press. We will share our learnings from the first issue working directly with writers and artists to inform features and user experience of our tool. We will present how Distributed Press will help publish works to the DWeb (IPFS, Hypercore, Scuttlebutt), enable monetization, add a disintermediated social layer to publishing, and verify content, in a manner aligned with our values. Finally, we will talk about radical practices that ensure decentralization extends into governance, decision making, and community building.

Unfortunately, the GNU Radio SDR framework does not directly support such devices. Many workarounds have been developed to allow accelerator devices to be used within GNU Radio, but each comes with performance and/or flexibility tradeoffs. To solve these problems work is currently underway to develop generic support for accelerator devices within GNU Radio itself. The focus of this work is to modify GNU Radio to allow support for custom buffers. Custom buffer support will allow GNU Radio to directly utilize device specific buffers (e.g. DMA buffers) and therefore eliminate the need to double copy in order to move data into and out of an accelerator device. Furthermore, the custom buffer concept can be extended to allow “zero copy” data access between two kernels on the same accelerator device. This presentation will cover the design and current status of custom buffer support for GNU Radio.

The situation in the database space is more complicated. There is the SQL family of databases, but in so far the SQL standard is too limited. To be ready for every situation possible you need to re-invent yourself all the time, for each database system its idiosyncrasies. What about a database paradigm that builds upon existing knowledge, that you can re-use in many situations and program with your favorite Scheme?
After brief note on database history, we will dive into what is a database, and how to choose one. Then we will look into the particular case of Ordered Key-Value Stores (OKVS), explain and demonstrate how with a single interface they cover a large palette of use-cases, and a glimpse of it: so called relational, text and geometric with the help of a new representation. At last, we will see what are the downsides, and try to answer the question: will Ordered Key-Value remain a tool of the experts?

It is silicon-proven, having been used with Alliance auto-scaleable nsxlib Cell Libraries to produce ("tape out") NDA-free GDS-II files that resulted in successful working 180nm ASICs, and has been used in ASICs up to 800k gates. The input is HDL (verilog, VHDL, and yosys RTLIL) and the output is 100% complete GDS-II, with IO pads, cells, SRAMs all fully "Placed and Routed", ready for ASIC manufacture.
However unlike traditional P&R software (which may or may not have had, at some point in its development, a scripting language added as an afterthought), coriolis2 is written in a hybrid of c++ and python modules. Layout is done not by a file format that must be loaded by a GUI: layout for each ASIC is actually a python program that, through the coriolis2 python modules imported by that program, reads the HDL, reads the Cell Libraries, and, fully under parametric programmatic control, creates the layout.
This talk provides a demo walkthrough of coriolis2 in action, to produce an actual GDS-II layout including the IO Ring and IO Pads.

DESCRIPTION:Elephant flows appear irregularly, can consume almost half of the available bandwidth and are consequently associated with a host of issues. Securing elephant flows with IPsec is a well-known challenge to SDN and SD-WAN solutions on commodity hardware. The key problems for those developing solutions are:- How to seamlessly enable dedicated HW to accelerate IPsec processing when available?- How to distribute workloads to more CPU cores and maintain packets ordering to scale?- How to scale up/scale down the computer resource usage when the elephant flow appears and disappears?In this talk we will discuss our recent work done on open-source project FD.io/VPP to address the above problems. We will describe how we utilized and enriched the VPP architecture to accelerate on-demand IPsec elephant flow processing in a unified and seamless way.

Since the kernel already provides symmetric ciphers, we focus on asymmetric cryptography only, elliptic curves in particular.
Use used the mbed TLS library as the foundation and almost fully rewrote it to make is x40 faster. During our development we also use parts of WolfSSL library. While WolfSSL outperforms OpenSSL, it uses the same algorithms, which are 5-7 years of old. Tempesta TLS uses newer and more efficient algorithms from the modern cryptography research.
While we still improving performance of Tempesta TLS, the implementation already establishes 40-80% more TLS handshakes per second than OpenSSL/Nginx and provides up to x4 lower latency in several tests.
This talk covers following topics with plenty of benchmarks:
The fundamentals of elliptic curve computations and the most "hot spots"
Side channel attacks (SCA) and methods to prevent them
How the recent CPU vulnerabilities impact TLS handshakes
Basics of the new fast algorithms used in the Tempesta TLS
The design trade offs in OpenSSL, WolfSSL, mbed TLS, and Tempesta TLS
The funny assembly code with is more straightforward than C
Performance is a crucial property of software for both closed and open source software. Assuring that performance requirements are met in the CI process using benchmarks or load tests requires heavy manual effort for benchmark and load test specification. Unit tests often cover a big share of the use cases of a software and are maintained anyway. While they have some downsides for measuring the performance, e.g. since they test corner cases or use functional utilities like mocks, they still are a way of measuring realistic use cases with nearly no manual effort.
Therefore, we develop the tool Peass (https://github.com/DaGeRe/peass), which transforms unit tests into performance unit tests and measures their performance. The stand-alone tool Peass can be integrated into the CI-process using Peass-CI, which makes it possible to run performance tests with every build in Jenkins.

Coroutines, Kotlin's conciseness and syntactic sugar enabled the efficient codebase of scenery to integrate with popular image processing tools, and support Virtual Reality rendering, both on headsets and on distributed multi-projector systems like CAVEs. We'll show code, demos, lessons learned, and demonstrate how we use the framework in a visualisation software for end users, sciview, that we have also developed.

Knowing that a good document requires both good content and presentation, I proposed and led the creation of a simple workflow amenable to our team's software engineers and data scientists: treating the white paper text as code with technologies including Markdown, GitHub Enterprise, Pandoc, LaTeX, and a review process that gets the tooling out of the way in order to enable content authors to focus less on logistics and more on writing and reviewing. The result was that a team of seven engineers and data scientists created a 50-page document containing text, diagrams, equations, graphics, and more in just two weeks. The result greatly pleased our directors and executives. They praised our team not only for the incredibly valuable content but also for the professional appearance of the document. When they learned about the peer review process we used to create it, they wanted more teams to use it.
This talk focuses on the problems of passing around files by email or shared drives, the problems of collaborative editing of online documentation, and the problems we're still addressing in our solution that we've now used to author several significant internal documents.

We pick up pieces of different patterns and techniques, blindly applying them without understanding their implications, in an attempt to ship software. Testing and packaging become significant pain points for many developers, and this need not be so.
In this talk, Jason C. McDonald breaks down the best way to structure a Python project for maximum portability and maintainability...and more important, explain WHY these patterns exist.

This is why events such as FOSDEM are so essential to enable us to meet members of our communities face to face to create these essential connections. In 2020 the annual OSS physical event circuit was broken due to the pandemic, and was replaced with online versions. It has meant we spent the year on weekly zoom project team/ steering committees & more meetings online. Then we have yet more zoom webinar or some other online tool for our flagship OSS events. This can be sufficient when you know the people on a mature community, as you may have met them before, but what for new OSS communities just starting out?. How can we get that personal connection that is needed to help avoid unnecessary conflicts due to simple misunderstandings. What people see in print, say in a gerrit review comment, can seem a lot more severe if you do not really know the person who had typed it. That is why I'd like to give my experience from 2020. Lessons I have learned and adapted in my meeting. To take the time to step back/zoom out in our OSS commnity meetings, and take just a little time so we can zoom in on the people.

Eviction flushing is necessary when all least recently used blocks are dirty (modifications exist in the buffer pool). Checkpoint flushing (writing out the oldest modified page first) allows the log checkpoint to advance, shortening the potential recovery time by logically discarding the start of the log. Any write of a persistent page must be preceded by a corresponding log write and optional doublewrite, to guarantee that crash recovery works.
We will cover some improvements in this area in MariaDB Server's version of InnoDB storage engine. We will also discuss how a database could be configured to minimize write amplification.

In this presentation Stefan will address questions every FOSS developer will have, when hearing about OpenHarmony for the first time. If you are curious about thearchitecture, used FOSS projects, or want to know more about contribution guidelines and start picking in the code this talk would be a good start.

I want to acknowledge the Coast Salish people including the səl̓ilwətaɁɬ təməxʷ (Tsleil-Waututh), Skwxwú7mesh-ulh Temíx̱w (Squamish), S’ólh Téméxw (Stó:lō), Stz'uminus, and xʷməθkʷəy̓əm (Musqueam) whose lands were stolen but have rights to these lands even today.
Google Scholar, Web of Science, Scopus, Dimensions, Crossref, Scite.ai, ... What used to be the home turf of for-profit publishers has become a buzzing field of technological innovation. Scholarly metrics, not only limited to citations and altmetrics, come from a host of data providers using an even wider range of technologies to capture and disseminate their data. Citations come as closed or open data, using traditional text processing or AI methods by private corporations, research projects or NGOs. What is missing is a language and standard to talk about the provenance of scholarly metrics.
In this lightning talk, I will present an argument why we need to pay more attention to the processes of tracing and patterning that go into the creation of the precious data that determine our academic profiles, influence hiring and promotion decitions, and even national funding strategies. Furthmermore, I present an early prototype of Metrics in Context, a data specification for scholarly metrics implemented in Frictionless Data. Additionally, the benefits and application of Metrics in Context is presented using both traditional citation data and a selection of common altmetrics such as the number of Tweets or FB shares.
[1] "Unceded lands are territories that were never signed away by the Indigenous people who inhabited them before Europeans settled in North America. In other words, this land was stolen. (It's worth noting that territories covered by treaties also weren't necessarily ceded — in many cases, the intent of the agreements was the sharing of territory, not the relinquishing of rights.)"

This makes it a really nice fit for micro-controllers, or otherwise hardware constrained environments (or to just use less resources in general). Based on my experiences with Nim and micro-controllers I'll dive into how meta-programming, DSLs, and Nims rich type system can be used to make nice readable code for micro-controllers without any added overhead compared to C. Both in terms of code-size, but also in terms of speed, in fact the code executed on the controller is pretty much the exact same thing, but with vastly improved ergonomics.

One of the reasons OSS Review Toolkit was started by its creators was a need to go beyond the usual allow/deny license policy in most SCA tools. For instance we wanted to be able to write checks with multiple levels of compliance depending on what was being reviewed or based on package meta data. In this session we will demonstrate how one can write license policy with checks/rules that take into account package metadata date or the code, license and product context.

For example, a Suricata alert might require the context of Zeek's connection logs for the alert to become actionable. Normally the best way to make such correlations is by manually identifying the flow tuple involved, in each of the monitor outputs involved, around the timestamps in question -- a tedious and error-prone task.
To simplify this process we're standardizing a straightforward algorithm, dubbed "Community ID" (https://github.com/corelight/community-id-spec), that produces short textual hashes that reliably identify network flows directly at the source. Flow correlation then becomes a straightforward string comparison operation. Popular open-source network monitoring solutions now include support for this emerging standard, including Suricata, Wireshark, and Zeek, and there's a growing library of reusable implementations in various common programming languages.
In this talk we will motivate the Community ID standard, report on its current implementation status, and demonstrate it to the community.

Reverse-engineering consists in studying an object (or a method) in order to determine its internal functioning. Reverse-engineering consists in identifying a precise case, making a recognition, disassembling step by step and piece by piece, then understanding the mechanism; and finally reassembling the object (or the method) with a new value proposition in its operation.
We are experimentally trying to revisit the practice of reverse-engineering to explore these possible and effective contributions in the case of investigation (journalism, activism, science, art).
