manual &amp; automated testing with over 1 million downloads. It has been made by testers and licensed under GPLv2. Our mission is to transform the testing process by making it more organized, transparent &amp; accountable for everyone on your team. Kiwi TCMS is used during software testing and quality assurance to collect information about what, when and how has been tested. This information is later used when making a go/no-go decision before a release, monitoring and planning the workload of the QA team or answering questions like "How did we test this?" and "Why didn't we catch this bug before?"!

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

Recently, this trend has penetrated the fields of crime and police research. The presentation highlights use cases of big data computation and HPC for typical datasets in crime science: crime records, emergency call data, and police GPS data. The focus lies on spatiotemporal applications (i.e., geocoding, map matching, spatial and temporal algorithms). The datasets come from a collaborative project with a Belgian police force and encompass approximately 200,000 crime records and 400 million individual GPS datapoints (x and y coordinates + timestamp). The project aims at establishing the crime preventive effect of police patrols through a longitudinal research design. Besides offering novel computational solutions for crime scientist, these kinds of datasets introduce important ethical considerations as well as potential biases in human-led data entry and collection. These considerations underline the need for social scientists to become more literate in the computational sciences and support the framework of ‘crime science’ as a discipline of exact methods and data sources.</p> PUBLIC CONFIRMED HPC, Big Data, and Data Science https:/fosdem.org/2022/schedule/event/big_data_police_crime/ D.hpc Philipp M.

It does so by taking a compositional approach that reduces the complexity of managing configuration from a combinatorial problem to a linear problem. CUE is based on 20 years of experience in the field of configuration. Its declarative, aspect-oriented approach is powerful yet simple, making it possible to manage large amounts of configuration data and policies in multiple formats (JSON, YAML, Protocol Buffers, OpenAPI, etc.) with relative ease. It also makes CUE well suited to a wide range of applications.</p> <p>This all sounds great! But for someone new to CUE, it may not be obvious how to get started.</p> <p>In this talk, Marcel van Lohuizen and Paul Jolly start with a quick overview of CUE the language, then move on to present practical examples of CUE in action, including common patterns for validation, policy, integration with existing non-CUE configuration and more.

They are rich in text, images, objects, people and events, heterogeneous, eminently linkable and sparse-matrix. Personal computers, the internet and other accessible technologies have spawned an exploding field (or fad?) known as Digital Humanities (DH), and opened exciting new horizons for research and public engagement.</p> <p>However, this technological turn has created many problems for a poorly funded research culture with 1-3 year grant funding cycles - choice of appropriate technology, finding and retaining technical staff, initial and ongoing costs, sustainability ... The outcome is often least-effort and inadequate technology (eg. spreadsheets) or ad hoc development, incomplete functionality, maintenance nightmares, data silos and rapid end-of-funding decay; only rich or statutory organisations can maintain a multi-component system for long. Heurist aims to overcome these problems by mutualised Open Source development, schemas stored as editable data rather than fixed structures, demand-driven priority development, and free centralised services and maintenance.</p> <p>In this presentation I will outline the evolution of our development process, from haphazard experimentation and many costly unused features (2005 - 2009) to a coherent, stable but evolving structure and Extreme Programming (aka living dangerously!), driven by immediate user requirements and incremental daily interface refinement. I will outline some of the fundamental principles we use to maintain backwards compatibility, stability, rapid development and low cost of maintenance for such a complex beast and for so many projects, on a self-funding staff of just 3 FTE. I also hope to attract some technical collaborators, as most of our users are (by design) non-technical.</p> PUBLIC CONFIRMED Open Research Tools and Technologies https:/fosdem.org/2022/schedule/event/open_research_heurist/ D.research Ian Johnson PUBLISH 12733@FOSDEM22@pentabarf.org 12733 mariadb_model mariadb_model MariaDB Server's new release model en en_US MariaDB Server 2022-02-05 10:05:00 +0100 2022-02-05 10:25:00 +0100 00:20:00:00 20220205T100500 20220205T102500 00:20:00:00 MariaDB Server's new release model <p>As was announced in December 2021 https://mariadb.org/new-innovation-release-model/, MariaDB Server now has a new release model, with more frequent major releases.

OSPOs often oversee aspects of a company’s open source license compliance process and supply chain as one of the first activities.

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

Based on this experience, we will also discuss the conditions we consider relevant for the durability of the software in a new interconnected phase.

Many tools, such as ImageJ, QuPath or CellProfiler are heavily used by researchers to quantitatively interpret those complex images. These tools perform tasks such as normalization, image segmentation, image masking or feature extraction. However, these tools are designed for usage on local workstations with a GUI and for the most part only allow vertical scaling to deal with an increase in dataset size. This limited scalability poses a problem as bioimaging datasets keep growing in volume.</p> <p>Here, we introduce Scalable Cytometry Image Processing (SCIP). SCIP is an open-source tool that implements single-cell bioimage processing on top of Dask, a framework for distributed computing written in Python. By utilizing Dask to execute all computations, scalability is integral to the software allowing it to be executed on high performance computing clusters. Dask's smart task scheduling ensures computational resources are used efficiently. SCIP also takes advantage of Dask features such as fault tolerance, load balancing or data locality. This allows SCIP to process large datasets more efficiently and more robustly compared to other tools.</p> PUBLIC CONFIRMED HPC, Big Data, and Data Science https:/fosdem.org/2022/schedule/event/scip_scalable_cytometry_image_processing_dask/ D.hpc Maxim Lippeveld PUBLISH 12820@FOSDEM22@pentabarf.org 12820 arcon_rust_streaming arcon_rust_streaming Uncovering Arcon: A state-first Rust streaming analytics runtime en en_US HPC, Big Data, and Data Science 2022-02-05 10:30:00 +0100 2022-02-05 11:00:00 +0100 00:30:00:00 20220205T103000 20220205T110000 00:30:00:00 Uncovering Arcon: A state-first Rust streaming analytics runtime <p>In this talk, I will present Arcon, a Rust-native streaming runtime that integrates seamlessly with the Apache Arrow ecosystem.

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

Over the years, I have contributed to a variety of free and open source software projects, and since 2019, I have developed and maintained <code>textnets</code>, a Python package for text analysis that represents collections of texts as networks of documents and words, providing novel possibilities for the visualization and analysis of texts. In my field, such software development efforts are not usually rewarded, but I have been very fortunate. My academic superiors have been supportive of my endeavors, and a publication in the <em>Journal of Open Source Software</em> also helped me get official recognition for this work in the standard currency of my field.</p> <p>While I developed <code>textnets</code> to scratch my own itch, I seek to make the package widely available by providing extensive documentation and making it easily installable across multiple platforms. This part of my software development work -- learning the intricacies of version control, package managers, continuous integration testing, and dependency management -- puts me in a position to learn not just about the technical side of coding, but about the social side of the choices developers make. At least in the Python world, the way you learn about what dependencies to use, if any, and how many, is informed by norms more than by technical considerations, and the same is true for much else. By engaging in software development work, I engage in a version of the research method of participant observation -- learning by taking part -- that sociologists have called observant participation -- becoming part of what you want to learn about. In my case, I want to learn not just about software development and its culture and norms, but the wider world of free software, hacker culture, artistic practice based on FOSS tools, and more.</p> <p>In my talk, I provide some background to the development of <code>textnets</code>, give a brief demonstration of the package's features, and finally reflect on my experiences engaging in observant participation as well as some of the insights I have gained and still hope to gain.</p> PUBLIC CONFIRMED Open Research Tools and Technologies https:/fosdem.org/2022/schedule/event/open_research_textnets/ D.research John Boy PUBLISH 12856@FOSDEM22@pentabarf.org 12856 open_source_license_compliance_project open_source_license_compliance_project Developing an open source license compliance project : our trials, tribulations and achievements en en_US Software composition and dependency management 2022-02-06 10:40:00 +0100 2022-02-06 11:00:00 +0100 00:20:00:00 20220206T104000 20220206T110000 00:20:00:00 Developing an open source license compliance project : our trials, tribulations and achievements <p>This talk aims at presenting our trials and tribulations as well as our achievements in designing a compliance software project for open source licenses.</p> <p><em>"Are all module licenses in our software project compliant with each other ?"</em> Many of our customers have asked us this question even though they already had a plethora of software solutions (not always FOSS software) dealing with this topic.

This code safely modifies page tables that are concurrently used by the CPU. Usually, unit tests only check whether the state after an operation meets the expectation of the programmer. In contrast, Hedron employs completely deterministic unit tests that show that the CPU will always see a valid virtual memory mappings while a page table manipulation is in progress (for the tested cases).</p> <p>The goal of this task is to show that unit tests can be a powerful tool even for properties of code that are usually not deemed unit testable.</p> PUBLIC CONFIRMED Microkernel and Component-based OS https:/fosdem.org/2022/schedule/event/jstecklina/ D.microkernel Julian Stecklina PUBLISH 12615@FOSDEM22@pentabarf.org 12615 dependencymanagement dependencymanagement Free Software, Dependency Management, and what I got wrong at FOSDEM 21 en en_US Raku 2022-02-05 10:50:00 +0100 2022-02-05 11:35:00 +0100 00:45:00:00 20220205T105000 20220205T113500 00:45:00:00 Free Software, Dependency Management, and what I got wrong at FOSDEM 21 <p>Writing Free Software is very different from writing proprietary software for a huge software company like Google or Facebook – the team size, incentives, and likelihood of turnover are all completely different – and, as a result, the ideal languages are very different as well.

There is now a concerted global interest in open science uptake, but barriers exist. The formal training curriculum in most, if not all, universities in the global South do not equip students with the knowledge and tools to practice open science in their research or develop open-source tools. To work openly, collaboratively, and build a community, there is a need for awareness and training in using and developing open science tools. Through the OpenScienceKE framework, we developed a model to narrow the gap: the sensitize-train-hack-collaborate model. Using the model, we sensitised through seminars, trained on the use of tools through workshops, applied the skills learned in training through hackathons to develop open-source tools collaboratively.

Such a practice poses a variety of challenges in terms of website design and development ; but also and maybe more importantly, it asks for experimenting specific workflows for coordinating a variety of expertises ranging from social sciences disciplines (history, sociology, etc.) to data science, information design and web-related skills. It also reconfigures, for the research processes themselves, the relationships between activities of (data-related) enquiry and (communication-oriented) writing, creating a renewed space for discovery, invention and verification for the data sustaining a given argument or narrative.</p> <p>Relying on recent experiments in making collective digital publications grounded in sociology of technology (https://medialab.github.io/carnet-algopresse/#/publication/en) and history of economy (https://medialab.github.io/portic-storymaps-2021/), this talk accounts for the diverse challenges arising from such activities of “data visualization-driven writing”, and some strategies we used to cope with them. It describes and compares the technical and methodological workflows we developed in order to simultaneously develop text, datasets and visualizations, taking into account a variety of aims, data materials, and distribution of skills. Doing so, it advocates for an extended understanding of the notion of “academic writing”, encompassing the practices of writing software, data and diagrams. Such an extended understanding, we argue, is necessary to design and develop writing workflows allowing to foster a multimodal and scientifically productive dialogue between these heterogeneous practices, taking full advantage of the web publication format as a research situation.</p> PUBLIC CONFIRMED Open Research Tools and Technologies https:/fosdem.org/2022/schedule/event/open_research_writing_data_visualization/ D.research Robin De Mourat PUBLISH 12593@FOSDEM22@pentabarf.org 12593 unit_testing_linux_drivers unit_testing_linux_drivers Unit testing Linux kernel drivers en en_US Testing and Automation 2022-02-05 11:20:00 +0100 2022-02-05 11:55:00 +0100 00:35:00:00 20220205T112000 20220205T115500 00:35:00:00 Unit testing Linux kernel drivers <p>The technical presentation is about how to use mocks to unit test Linux kernel drivers.

In ToroV, applications run as Virtual Machines without the need of an OS, unikernel nor device-model. ToroV combines a minimalist Virtual Machine Monitor and a virtualized guest program communicating through POSIX APIs. When the guest application requires to open or write a file, it just invokes the VMM using hypercalls. The VMM intercepts those hypercalls, processes the request, and returns to the guest. The sysadmin defines the ACL (Access Control List) of authorized hypercall per virtualized guest application. This allows the user to control the host’s surface that is exposed to the guest. In this talk, we propose to present the ToroV architecture together with several ongoing experiments. For example, the minimalist VMM allows us to boot up a VM in KVM in less than 6 ms. Also, we show how we debug guest applications by simply using GDB and the KVM API for debugging. During the talk, we discuss the main differences with unikernels and containers and how ToroV gets the best of both worlds. Also, we present the main differences with gVisor, which is a similar project from Google.</p> PUBLIC CONFIRMED Virtualization and IaaS https:/fosdem.org/2022/schedule/event/vai_torov/ D.virtualization Matias Vara PUBLISH 12398@FOSDEM22@pentabarf.org 12398 multidimensional_bloom_filters multidimensional_bloom_filters Multidimensional Bloom Filters A Survey of What, When, Why en en_US HPC, Big Data, and Data Science 2022-02-06 11:30:00 +0100 2022-02-06 12:00:00 +0100 00:30:00:00 20220206T113000 20220206T120000 00:30:00:00 Multidimensional Bloom Filters- A Survey of What, When, Why <p>Claude Warren will present an overview of his recent work to implementing multidimensional Bloom filters.

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

In this talk we present what we learned through our experience, how we tune the codes for MI100, how we expect to tune them in the future for LUMI GPU, the AMD MI250X, compare the previously mentioned programming models on some kernels across the GPUs, present a performance comparison for single precision benchmark, discuss the updated software roadmap, and a brief update for the porting workflow.</p> PUBLIC CONFIRMED HPC, Big Data, and Data Science https:/fosdem.org/2022/schedule/event/utilizing_amd_gpus/ D.hpc Georgios Markomanolis PUBLISH 12661@FOSDEM22@pentabarf.org 12661 continuous_testing_in_cloud continuous_testing_in_cloud Continuous testing in a cloud based infrastructure using virtualization and real hardware in the loop en en_US Testing and Automation 2022-02-05 12:00:00 +0100 2022-02-05 12:40:00 +0100 00:40:00:00 20220205T120000 20220205T124000 00:40:00:00 Continuous testing in a cloud based infrastructure using virtualization and real hardware in the loop <p>The concerns about code complexity, cybersecurity and LTS have made a continuous testing infrastructure a must have.</p> <p>The tests must take place both in virtual and real target.

It is concerned especially with these interactions between the trusted and untrusted worlds. This notion underpins Guardian: an open-source tool that we have created to help enclave developers check their enclaves are orderly before they are deployed. It automatically validates enclaves and reports violations to our notion of orderliness.

It combines a powerful syntax and safety features based on the design-by-contract principle with a simple intermediate representation that enables powerful optimizing compilers and static analysis tools to verify correctness aspects.</p> <p>This talk will focus on Fuzion's aspects related to safety-critical software development. A fundamental idea of Fuzion is to provide a simple language at a high level of abstraction and move implementation decisions from the developer to the compiler. To enable this, the language defines a simple but powerful intermediate representation for static analysis tools to operate on.</p> <p>Furthermore, pre- and post-conditions for design-by-contract are provided in a way that enables different levels of verification: static analysis as well as dynamic checks at different levels from safety to debugging.</p> <p>Fuzion does not support exceptions, a run-time error has to be part of the result of a call and must be checked explicitly. Fuzion does not support dynamic loading of code. Numeric operations such as 'infix +' check for overflow.</p> <p>Fuzion applications consist of a set of library modules and a main modules. Modules are verified for correctness individually as well as whole applications.

The datasets had different sizes 10-20 years ago and the cost model is not always accurate for current workloads.</p> <p>Thus, there is now an ongoing effort to significantly improve the calculations that the MariaDB Optimizer is doing. With the addition of JSON Histograms, the range optimizer is one of the most impacted modules. The end goal of this effort is to provide the user with a better query optimizer, but also put the user in control and allow the user to tweak many more parameters than were previously available.

As a result, new languages are often engineered (or "over-engineered") for that glorious future where millions of programmers spend their lives working with the language, and a small army is maintaining the compiler and related tools. But how would you design a language that assumes this bountiful future will never arrive? A language that, even in the best of circumstances, will always be obscure and secondary? Futhark is a programming language designed for a very specific domain: high-level, deterministic, data-parallel number crunching. It explicitly disavows general-purpose use, and it is absolutely not possible to write full applications in it. Thus, even if Futhark somehow managed to become the largest conceivable success and completely dominate its domain, that would not translate into very many programmers. And even then, it would at best be a secondary or third language for most of its users.</p> <p>In this talk I will talk about how such a perspective has affected the design of the Futhark language and its tools. To a first approximation, this is just the "principle of least surprise" applied to every part of the language and ecosystem. As a niche language, Futhark's novelty budget is quite limited, and its users will not have the inclination to learn about syntactical subtleties, elaborate package managers or build systems. At the same time, it's trying to innovate in a challenging domain, so some things definitely will have to be novel. Balancing these concerns has been interesting, and my experiences are perhaps even useful for designers of languages, tools, or systems in similar situations.</p> PUBLIC CONFIRMED Declarative and Minimalistic Computing https:/fosdem.org/2022/schedule/event/langdesert/ D.minimalistic Troels Henriksen PUBLISH 12479@FOSDEM22@pentabarf.org 12479 reporting_vulnerabilities_within_complex_software_environment_cve_bin_tool reporting_vulnerabilities_within_complex_software_environment_cve_bin_tool Reporting vulnerabilities within a complex software environment Using the CVE-Bin-Tool en en_US Software composition and dependency management 2022-02-06 12:40:00 +0100 2022-02-06 13:00:00 +0100 00:20:00:00 20220206T124000 20220206T130000 00:20:00:00 Reporting vulnerabilities within a complex software environment- Using the CVE-Bin-Tool <p>Detecting known software vulnerabilities is hard to do perfectly. However, the CVE Binary Tool is a tool which has been designed to analyse and trace dependencies by performing a binary analysis that attempts to detect the versions of the libraries in compiled applications in order to determine the vulnerabilities that may be present. Since the tool was initially released, the number of libraries which can be detected has steadily increased so now over 100 libraries can be detected primarily through the effort of students working under the Google Summer of Code (GSOC) programme. Supported libraries have typically been prioritised based on the number and frequency of vulnerabilities reported in the CVE database. The latest version of tool released at the end of 2021 has added capabilities to perform vulnerability scanning of Linux distros, Python applications and to consume Software Bill of Materials (both the SPDX and CycloneDX formats are supported).

Managarm is a pragmatic microkernel-based OS with a focus on asynchronous operations. The talk covers various aspects of the microkernel, such as its IPC model, resource management, and user space API. Managarm's microkernel employs a capability-based design to manage hardware resources. In contrast to current mainstream OSes, Managarm's system calls never block but report completion asynchronously whenever possible. This includes system calls for common tasks such as memory management or inter-process communication (IPC). A lock-free ring buffer is used to quickly deliver asynchronous completion notifications to user space. Managarm implements a POSIX subsystem to be able to run various well-known UNIX applications (e.g., a Wayland desktop) on top of the microkernel. This subsystem is implemented entirely in user space. The kernel uses various acceleration strategies to to efficiently support this use case.</p> PUBLIC CONFIRMED Microkernel and Component-based OS https:/fosdem.org/2022/schedule/event/agrinten/ D.microkernel Alexander van der Grinten PUBLISH 13098@FOSDEM22@pentabarf.org 13098 mqtt mqtt Benefits Of MQTT For IoT Apps And Beyond en en_US Friends of OpenJDK 2022-02-06 12:40:00 +0100 2022-02-06 13:20:00 +0100 00:40:00:00 20220206T124000 20220206T132000 00:40:00:00 Benefits Of MQTT For IoT Apps And Beyond <p>A quick study on several popular MQTT brokers!</p> <p>We will learn about the benefits of MQTT, which has become the de facto standard for IoT messaging.

LLVM being emerging compiler framework, there was some gap to be bridged w.r.t. Fortran language debug info generation. This is because Fortran language has few features which are very powerful, as compared to other languages.</p> <p>Fortran dynamic arrays are one such powerful language feature. There are variety of arrays like adjustable array, assumed shape, assumed size, assumed rank, allocatable and pointer arrays. LLVM generated debug info was not sufficient to debug these many variety of arrays with GDB/LLDB. The LLVM was lacking support for multiple DWARF operators (DW<em>OP</em>push<em>object address, DW</em>OP<em>over), DWARF attributes (DW</em>AT<em>data</em>location, DW<em>AT</em>allocated, DW<em>AT</em>associated, DW<em>AT</em>rank) and a DWARF TAGs (DW<em>TAG</em>generic_subrange). Other than these, existing support for DISubrange was not sufficient to handle Fortran arrays. The same was true for Fortran strings which is not mere pointer to character type and needed more support from LLVM. Other features which needed similar LLVM support for debugging were Fortran modules, namelist and signed constants etc.</p> <p>All these enhancements made in LLVM are as per DWARF4 or DWARF5 specification for the Fortran language. These enhanced debug info are used by GDB/LLDB and user debugging experience is improved now while handling these Fortran features with GDB/LLDB. In order to make use of these enhanced debug info emitted by LLVM, GDB/LLDB is also enhanced in cases where required. With these enhancements added now in LLVM, Fortran program debugging experience with the clang/flang emitted programs are on par with gcc/gfortran emitted programs and in some cases it’s even better than gcc/gfortran.</p> PUBLIC CONFIRMED LLVM https:/fosdem.org/2022/schedule/event/llvm_fortran_debug/ D.llvm Alok Sharma Bhuvanendra Kumar N PUBLISH 13012@FOSDEM22@pentabarf.org 13012 security_sbom security_sbom The distinctive qualities of Software Bill of Materials en en_US Security 2022-02-06 13:00:00 +0100 2022-02-06 13:45:00 +0100 00:45:00:00 20220206T130000 20220206T134500 00:45:00:00 The distinctive qualities of Software Bill of Materials <p>Software Bill of Materials (SBOMs) have emerged as a powerful tool for guiding supply chain security in modern software development environments.

In this talk, I discuss how these features allow the initialization of a container data type for heterogeneous values (a-la JSON) without the need of crutch functions (like the usual "+"). Such an structure could be used for compiled-in definitions but, more ambitiously, a relatively simple parser for a strict subset of Ada could leverage this data structure for natural-looking (to the Ada programmer) configuration files.

On resource-constrained devices, an RTOS such as Zephyr is able to even run on devices with as little as a few hundred KB of RAM and storage.</p> <p>However, the kernel is a small part of the device's software stack - there is middleware, application frameworks, security policies, key management, OTA and multi-year maintenance that the company needs to budget into the device's engineering support costs.</p> <p>Viewing the Linux and RTOS ecosystems as two parts of a single product platform allows for a coherent view of both ecosystems by developers. You want to make sure that you can apply the same set of software configurations and policies across both ecosystems e.g. library versions, compatible protocol suites, security configurations, OTA mechanisms and even a single set of IP compliance tools.</p> <p>As an example, when you decide you want to secure all your network communications out-of-the-box in your product platform, you need to:</p> <ul> <li>Find an SSL library that'll fit both footprints</li> <li>Configure it to have a coherent set of modern ciphers compatible across the two ecosystems</li> <li>Get the various protocol libraries to build against the chosen SSL library</li> <li>Create key provisioning tools that can work across the two ecosystems</li> <li>Perform interoperability tests</li> </ul> <p>Now repeat this exercise across every key component of the OS - security policy, networking features, OTA, toolchain hardening, IP compliance tools and you end up with a meta-project that spans and contributes to both ecosystems.</p> <p>We've started to build such a open product platform with opinionated defaults that follow community best practices with Eclipse Oniro.

Unikernels represent a compile-time specialization strategy and leverage the joining of user and kernel space via a library Operating System in order to achieve this, offering as a result incredible runtime performance whilst increasing application security via isolated hardware virtualization. As Unikraft, an open-source unikernel SDK and library Opeating System toolkit, has grown over the last few years, the number of available off-the-shelf applications, interpreted languages, libraries, target hypervisors and architectures has grown significantly. In order to ensure consistency between builds, prevent bugs and performance regression, and to allow for new features, a massive effort has been undertaken to facilitate massive build permutations of specialized unikernels which target and include variations of this growing ecosystem based on new commits and Github Pull Requests. In this talk, we discuss the journey of this undertaking, highlight and demo several CI/CD solutions in this space with Concourse, and how we are continuing to expand the ecosystem to automatically and intelligently build unique additional performance-oriented permutations from configurations available in the underlying libOS.</p> PUBLIC CONFIRMED Continuous Integration and Continuous Deployment https:/fosdem.org/2022/schedule/event/massive_unikernel_matrices_with_unikraft_concourse_and_more/ D.cicd Alexander Jung PUBLISH 12387@FOSDEM22@pentabarf.org 12387 lt_openhps lt_openhps Rapid Prototyping of a Positioning System Using the OpenHPS Framework en en_US Lightning Talks 2022-02-06 13:40:00 +0100 2022-02-06 14:00:00 +0100 00:20:00:00 20220206T134000 20220206T140000 00:20:00:00 Rapid Prototyping of a Positioning System- Using the OpenHPS Framework <p>The creation of a positioning system has use cases for indoor, outdoor and even small-scale deployments.

However, Users are unsatisfied due to delays in getting test results and Imprecise diagnosis. Misdiagnosis is usually experienced since most health care facilities use only Widal test without confirmation of results with a second test method.

The simplification of IaaS appears ideal (in theory) but providers and users are presented with several challenges: providers aim to reduce infrastructure maintenance overheads; users require isolation, flexibility and programming freedom.</p> <p>Serverless deployments are mostly backed by sandboxed containers. To enable programming freedom for users, providers allow the use of containers for function deployment, however, to ensure strict isolation, these containers are sandboxed in VMs. As a result, this bloated stack brings complicated maintenance costs: (a) several layers of abstraction between the user function to be executed and the actual execution environment; (b) increased attack surface; (c) increased request-to-exec time; (d) reduced set of feature availability for functions (hardware acceleration).</p> <p>Unikernels promise fast boot times, small memory footprint and stronger security but lack in terms of manageability. Additionally, Serverless frameworks only support containers. Moreover, unikernels provide a different environment for applications, with limited or no support for widely used libraries and OS features. This issue is even more apparent in the case of ML/AI workloads. ML/AI libraries are often dynamically linked and have numerous dependencies, which directly contradict the statically linked notion of unikernels. Finally, hardware acceleration is almost non-existent in unikernel frameworks, mainly due to the absence of suitable virtualization solutions for such devices.</p> <p>In this talk, we present the design of a flexible serverless framework designed for the cloud and the edge, backed by unikernels that can access hardware accelerators. We go through the components that comprise the framework and elaborate on the challenges in building such a software stack: we first present an overview of the necessary components of a serverless framework; then we focus on the function execution framework based on two popular unikernel frameworks; finally, we present a hardware acceleration abstraction to expose semantic acceleration functionality to workloads running on top of this framework.</p> <p>A short demo of the working components will be presented, discussing the challenges and trade-offs of this approach.</p> PUBLIC CONFIRMED Microkernel and Component-based OS https:/fosdem.org/2022/schedule/event/anano/ D.microkernel Anastassios Nanos Charalampos Mainas PUBLISH 13544@FOSDEM22@pentabarf.org 13544 ost2 ost2 OST2: A new way to grow security talent for open source projects Open Security Training 2 en en_US Open Source Firmware, BMC and Bootloader 2022-02-05 13:50:00 +0100 2022-02-05 14:45:00 +0100 00:55:00:00 20220205T135000 20220205T144500 00:55:00:00 OST2: A new way to grow security talent for open source projects- Open Security Training 2 <p>In this talk, we'll describe how OpenSecurityTraining2 (OST2) can help grow security talent and awareness on open source projects, and we'll use the coreboot open source firmware as a case study.</p> <p>Newly structured as a 501c3 non-profit, OST2's core goal is to provide free and open training that helps increase system security.

Granting access to a very specific resource is easy. A problem comes up when one wants to grant access to a whole database <em>except</em> for a particular resource (table, column, etc.). The only solution thus far is to grant access to each individual resource and omit the ones that must not be accessible. Clearly this is not maintainable, nor practical.</p> <p>This is where the DENY command comes in. The gist of the feature: A user will not be able to access denied resources unless the deny is explicitly revoked.

Many ECS frameworks are oriented around components or entities, and systems use run time queries or filters to match their component data requirements against the live state.</p> <p>In this talk, a system oriented ECS is presented which removes all run time work for systems by storing execution state in the systems themselves.

As compiler engineers we experience an increase in demand for security-related features: we simply work on security-related features more often. We find it tough to analyze whether the hardenings we implement are easy or hard to circumvent by attackers. After chatting about this with many compiler developers, our experience is that most feel their work would benefit from a deeper understanding of attacks and hardening techniques. After having looked around, we didn't find much educational material that gives a broad overview, covering all aspects compiler developers ought to know about. Therefore, we recently started an open source book titled "Low Level Software Security for Compiler developers" at https://github.com/llsoftsec/llsoftsecbook/. It aims to improve the industry-wide knowledge about security hardening in compilers and related tools; ultimately leading to more innovation and better implementations of security features. In this presentation, we'll explain the rationale for this new open source project in more detail. We will discuss what content we have so far and what content we plan to add. The project very much welcomes new contributors: we need more new content, more review of content, discussion of ideas for how to make the book better, improvement in the design and layout of the produced HTML and PDF output, etc. We hope this presentation will reach both anyone interested in learning more about low-level software security and anyone interested in helping to grow this project further.</p> PUBLIC CONFIRMED LLVM https:/fosdem.org/2022/schedule/event/llvm_llsoftsecbook/ D.llvm Kristof Beyls PUBLISH 12617@FOSDEM22@pentabarf.org 12617 minimalsyntaxes minimalsyntaxes Knowledge Management Through Minimal Syntaxes Appreciating How Terse Syntaxes Are Capable of Being Combined In Unexpected Ways en en_US Declarative and Minimalistic Computing 2022-02-06 14:35:00 +0100 2022-02-06 15:05:00 +0100 00:30:00:00 20220206T143500 20220206T150500 00:30:00:00 Knowledge Management Through Minimal Syntaxes- Appreciating How Terse Syntaxes Are Capable of Being Combined In Unexpected Ways <p>Presentation of the main components behind gLean - a knowledge-management application which treats problem-domains as a collection of blocks. gLeans USP is in choosing terse components which syntactically do not impede each-other - permitting collections of block to be parsed and interpreted with minimal concerns for complexity.

Despite being fundamental, they are rarely part of the curriculum in universities, thus undergrad and early career researchers often struggle to code data analysis pipelines and to automate data collection from experimental setups. Neurosciences, in particular, relies a lot on these skills, with behavioural experiments planning, design of the testing boxes, data visualisation and analysis. To Successfully complete these tasks, researchers need to acquire a significant level of skill in programming and hardware design. To address these problems, we are developing a flexible open hardware platform to lower the barrier in creating experimental setups: BeeHive. It consists of a main board, which nests an ESP32 microcontroller, and several dedicated “daughter boards”, each designed to perform one function (e.g. one board senses temperature, another controls motors, etc). These boards are connected to one another using a standard system already used by other Open Hardware systems, so that there is no need to reinvent the wheel. We can then focus on developing things that are not available yet. The system runs MicroPython, which is a Python derivative for microcontrollers. This architecture allows users to be in control of everything that the platform is doing while also providing plenty of room for completely new applications. Modular structure helps users to get familiar with electronic components already at entry-level expertise while Python is employed for its strong points such as simplicity and widespread usage. In this presentation we set out to explore the core concept of Beehive, describe existing and possible applications.</p> PUBLIC CONFIRMED Open Research Tools and Technologies https:/fosdem.org/2022/schedule/event/open_research_beehive/ D.research Andre Maia Chagas Ihor Sobianin PUBLISH 12541@FOSDEM22@pentabarf.org 12541 comparing_dpdk_rcu_and_user_space_rcu_library comparing_dpdk_rcu_and_user_space_rcu_library Faster memory reclamation with DPDK RCU Comparing the DPDK and Userspace RCU libraries en en_US Network 2022-02-06 14:40:00 +0100 2022-02-06 15:00:00 +0100 00:20:00:00 20220206T144000 20220206T150000 00:20:00:00 Faster memory reclamation with DPDK RCU- Comparing the DPDK and Userspace RCU libraries <p><a href="https://www.dpdk.org">DPDK</a> added a RCU library with a novel method to reclaim resources.

FlexOS is an OS allowing users to easily specialize the safety and isolation strategy of an OS at compilation/deployment time, instead of design time. Depending on the configuration, the same FlexOS code can mimic a microkernel with multiple address-spaces, a single-address-space OS with Intel MPK compartments, or many other OS isolation approaches.

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

An Edge Cluster, built on open source technologies that already exist in the Linux operating system, is a hyperconverged functional set of managed objects that include storage, network, and host resources. An Edge Cluster provides all the resources needed to run virtualized or containerized applications. OpenNebula’s management services, including scheduling, monitoring and life-cycle management, run in the cloud Front-end and orchestrate from there the local or remote Edge Clusters. The Front-end also provides access to the administration tools, user interfaces, and API. Although the requirements may vary depending on the number and size of the clusters and API load, the Front-end node only requires 8 GB of main memory and 4 cores. The Edge Cloud Architecture is able to provide a lightweight and easy-to-use storage platform for medium-sized clusters consisting of tens of nodes. OpenNebula’s Edge Cloud Architecture is able to manage hundreds of these clusters, as they operate autonomously in terms of networking and storage, and handle thousands of virtualized hosts and tens of thousands of virtualized applications. In this presentation we will explain in detail the deployment model for Edge Clusters, the specialized storage solution they incorporate (OneStor), and the performance benefits of this multi-cloud architecture as confirmed by the latest benchmarks.</p> PUBLIC CONFIRMED Virtualization and IaaS https:/fosdem.org/2022/schedule/event/vai_deploying_vms/ D.virtualization Alejandro Huertas PUBLISH 12679@FOSDEM22@pentabarf.org 12679 osd_when_to_invest_in_the_ux_of_scientific_open_source osd_when_to_invest_in_the_ux_of_scientific_open_source When to invest in the UX of (scientific) open source en en_US Open Source Design 2022-02-05 15:00:00 +0100 2022-02-05 15:25:00 +0100 00:25:00:00 20220205T150000 20220205T152500 00:25:00:00 When to invest in the UX of (scientific) open source <p>Software has become increasingly central to scientific research. Both software development and its use are essential activities for scientific teams. But investment in its production, maintenance, and adoption is often overlooked, and academia often fails to leverage best practices for software engineering from industry, the open source community, or elsewhere. Furthermore, investment in the user experience (UX) and usability of scientific software is largely an afterthought, if considered at all. As such, any future investment in UX is expected to have a disproportionately positive impact on adoption of scientific tools (i.e. broadening access) and on scientific discovery itself. Currently, the impact of this kind of investment (or lack thereof) is largely unknown.</p> <p>Scientific software stands to benefit from the learnings and current practices in open source design. This talk will explore the unique workflows and incentives of research institutions (and other contexts in which scientific software is produced) and map them to current practices of open source design with the intention of bringing to light the opportunities to better understand how and when to invest in the UX of research software, how to grow expertise in UX, and how to cultivate norms on peer-production platforms toward good UX practices.</p> PUBLIC CONFIRMED Open Source Design https:/fosdem.org/2022/schedule/event/osd_when_to_invest_in_the_ux_of_scientific_open_source/ D.design Elizabeth Vu PUBLISH 12723@FOSDEM22@pentabarf.org 12723 crowdsecurity crowdsecurity Crowdsecurity A participative IDS/IPS en en_US Miscellaneous 2022-02-05 15:00:00 +0100 2022-02-05 16:00:00 +0100 01:00:00:00 20220205T150000 20220205T160000 01:00:00:00 Crowdsecurity- A participative IDS/IPS <p>The <a href="https://github.com/crowdsecurity/crowdsec/">CrowdSec</a> project aims at providing a crowdsourced approach to common infrastructure defense problems, by distributing free &amp; open-source software allowing to protect yourself and share information about malevolent actors.

Unfortunately, despite many attempts to introduce isolation to the kernel, modern systems remain monolithic. Historically, software and hardware mechanisms introduce a prohibitively high overhead for the isolation of subsystems with the tightest performance budgets. Today, however, the balance of isolation and performance is starting to change with the development of Rust, arguably, the first practical programming language that achieves safety without garbage collection.</p> <p>RedLeaf is a new operating system developed from scratch in Rust with the goal to explore the impact of language safety on operating system organization, and specifically on the ability to utilize fine-grained isolation and its benefits in the kernel. In contrast to commodity systems, RedLeaf does not rely on hardware address spaces for isolation and instead uses only type and memory safety of the Rust language. Departure from costly hardware isolation mechanisms allows us to explore the design space of systems that embrace lightweight fine-grained isolation of kernel subsystems. We develop a new abstraction of a language-based isolation domain that implements a unit of information hiding and isolation of faults. Domains can be dynamically loaded and cleanly terminated. Building on RedLeaf isolation mechanisms, we demonstrate the possibility to implement end-to-end zero-copy, fault isolation, and transparent recovery of device drivers.</p> <p>To evaluate the practicality of RedLeaf abstractions, we implemented a subset of the POSIX interface as a collection of RedLeaf domains. RedLeaf's isolation mechanisms allow us to support the transparent recovery of device drivers. To demonstrate that Rust and fine-grained isolation introduce a practically-acceptable overhead, we develop efficient versions of 10Gbps network and PCIe-attached solid state-disk NVMe device drivers that match the performance of carefully-optimized kernel-bypass device drivers used in modern network and storage processing frameworks.</p> PUBLIC CONFIRMED Microkernel and Component-based OS https:/fosdem.org/2022/schedule/event/vnarayanan/ D.microkernel Vikram Narayanan Anton Burtsev PUBLISH 13004@FOSDEM22@pentabarf.org 13004 vulkan_borders vulkan_borders Fun with border colors in Vulkan An overview of the story behind VK_EXT_border_color_swizzle en en_US Graphics 2022-02-06 15:00:00 +0100 2022-02-06 15:45:00 +0100 00:45:00:00 20220206T150000 20220206T154500 00:45:00:00 Fun with border colors in Vulkan- An overview of the story behind VK_EXT_border_color_swizzle <p>The talk will give an overview of texel input operations according to the Vulkan specification text and how border colors, specified when creating Vulkan samplers, are supposed to fit in them.

As a friendly fork of CoreOS Container Linux it continues the project under a new name. The main features are the A/B partitions for automatic updates and rollbacks, and the integration of Ignition for declarative configuration on first boot. Declarative configuration is a key element for managing machines following the principle of Immutable Infrastructure, but causes friction if it means that the whole machine has to be reprovisioned for configuration changes. With Ansible instead of Ignition for the configuration management we can find a compromise by giving up on avoiding configuration drift due to leftovers of old configurations and their side effects. Out of this experience the idea was born to rerun Ignition on configuration changes. While the big hammer method is to reformat the filesystem and losing application data, a more fine-grained solution could exist by clearing only parts of the filesystem. This talk shows how to use Flatcar Container Linux with Terraform, Ignition, and Ansible, and ends with a proof-of-concept demo for Flatcar Container Linux to allow configuration changes through Ignition while avoiding configuration drift.</p> PUBLIC CONFIRMED Infra Management https:/fosdem.org/2022/schedule/event/flatcar_container_linux/ D.infra Kai Lüke PUBLISH 12681@FOSDEM22@pentabarf.org 12681 lispforeveryone lispforeveryone Lisp, but Beautiful; Lisp for Everyone en en_US Declarative and Minimalistic Computing 2022-02-06 15:05:00 +0100 2022-02-06 15:45:00 +0100 00:40:00:00 20220206T150500 20220206T154500 00:40:00:00 Lisp, but Beautiful; Lisp for Everyone <p>The old joke goes that LISP stands for "Lots of Irritating Superfluous Parentheses", but another spin could be "LISP Isn't Structurally Parenthetical".

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

This style of testing is admirably concise, but can lead to cryptic test messages that make it very difficult to determine what a test was attempting to check without opening up the file containing the failing test. At the other extreme, it's possible to write very expressive tests with a fluent, method-chaining API. For example, using the Chai.js assertion library, a test might read <code>beverages.should.have.property('tea').with.lengthOf(3)</code>. This allows tests to automatically generate much more useful messages but comes at the cost of creating a fairly complex test API with many new methods to learn.</p> <p>Raku's core Test module falls somewhere between these two extremes – it offers an API with a handful of functions that's easier to learn than a full fluent API but more expressive than simple <code>assert</code> statements. This is a sensible compromise.</p> <p>But I claim (assert?) that, with a bit of metaprogramming trickery, Raku lets us have the best of both worlds: we can have a zero-learning-curve test API that's just as simple as assert statements while <em>also</em> being just as expressive as a long chain of method calls in a fluent style. I'll present this style of testing, discuss its use in Raku, and consider ways in which Raku lets us improve on the status quo.</p> PUBLIC CONFIRMED Raku https:/fosdem.org/2022/schedule/event/simpletesting/ D.raku Daniel Sockwell PUBLISH 12713@FOSDEM22@pentabarf.org 12713 mysql_pitr_rockstar mysql_pitr_rockstar MySQL 8.0: Logical Backups, Snapshots and PITR like a rockstar en en_US MySQL 2022-02-06 15:15:00 +0100 2022-02-06 15:50:00 +0100 00:35:00:00 20220206T151500 20220206T155000 00:35:00:00 MySQL 8.0: Logical Backups, Snapshots and PITR like a rockstar <p>Logical dumps are becoming popular again.

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

Data repositories are improving in their ability to store this data, but there is a growing need for interoperability between disparate data sources and applications. The Breeding Application Programming Interface (BrAPI) project offers a solution to this problem with a standardized RESTful web service API specification. This specification provides a standard data model for the plant breeding domain, plus a well-defined set of methods for interacting with the data. The goal of the project is to promote interoperability, data sharing, and open source code sharing across organizations who produce and consume data in this domain. The BrAPI project is a community built project and that community is well established and continuously growing. The standard is built based on concrete use cases to solve real interoperability challenges faced by the community. Beyond the core standard, the community has built a variety of open source tools and resources to help build and test implementations of the specification. The community is also constantly producing new BrAPI compliant applications, analysis tools, and visualizations that will work with any BrAPI data source.</p> PUBLIC CONFIRMED Open Research Tools and Technologies https:/fosdem.org/2022/schedule/event/open_research_brapi/ D.research Peter Selby PUBLISH 12635@FOSDEM22@pentabarf.org 12635 conference_pgeu conference_pgeu Using pgeu-system to manage your conference en en_US Conference Organisation 2022-02-05 15:20:00 +0100 2022-02-05 16:20:00 +0100 01:00:00:00 20220205T152000 20220205T162000 01:00:00:00 Using pgeu-system to manage your conference <p>The pgeu-system is an integrated system for managing conferences.

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

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

AOSC OS/Retro, as an official branch of AOSC OS (the modern-device-facing mainline), runs a generally similar feature set - systemd, Glibc/Binutils/GCC/Coreutils/Util-Linux, X.org/Mesa, etc. and shares the same source tree with the latter.</p> <p>With over a year of spending our spare time on the project, tweaking features, designing a desktop experience, and optimising compiler flags, we have a usable distribution that could run on systems as slow as a 486SX, and as fast as "modern" Core Duo systems.

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

We will show how this impacts specifically flowgraphs that have CUDA enabled blocks as a concrete example.</p> PUBLIC CONFIRMED Free Software Radio https:/fosdem.org/2022/schedule/event/radio_gr3_10/ D.radio Josh Morman PUBLISH 13538@FOSDEM22@pentabarf.org 13538 openpower_workstation openpower_workstation OpenPOWER Ask Me Anything (AMA) *RESCHEDULED* en en_US OpenPOWER 2022-02-05 15:30:00 +0100 2022-02-05 16:00:00 +0100 00:30:00:00 20220205T153000 20220205T160000 00:30:00:00 OpenPOWER Ask Me Anything (AMA)- *RESCHEDULED* <p>This is the OpenPOWER Foundation Ask Me Anything session.

As such, extracting information from the machine can prove difficult. Moreover, because Unikraft offers support for running a single process at a time, alternate solutions had to be found for exporting data. Prometheus is a common tool used to collect and visualize data that offers decoupling from the observed system, as such, we saw it as a prime candidate for exporting information.</p> <p>Our solution was to port a Prometheus exporter inside Unikraft as a separate library and run it on a separate thread. Information from the unikernel is extracted by Prometheus through an intermediary library, named ukstore, that behaves like a simplified ProcFS. ukstore offers an easy method for accessing information and metrics from the system. Using Prometheus with Unikraft, we are thus able to extract performance metrics from highly-specialized virtual machines, store them in a time series database and display them using plots.</p> PUBLIC CONFIRMED Monitoring and Observability https:/fosdem.org/2022/schedule/event/unikraft/ D.monitoring Cezar Craciunoiu PUBLISH 12963@FOSDEM22@pentabarf.org 12963 not_only_python_kotlin_for_scripts not_only_python_kotlin_for_scripts Not only Python: Kotlin for scripts en en_US Kotlin 2022-02-06 15:40:00 +0100 2022-02-06 16:10:00 +0100 00:30:00:00 20220206T154000 20220206T161000 00:30:00:00 Not only Python: Kotlin for scripts <p>Python is ubiquitous in scripts, and it has definite benefits.

Following the pioneering work of the Gene Ontology at the turn of the century, the Open Biomedical and Biological Ontologies (OBO) Foundry was created to coordinate the development of a family of interoperable ontologies sharing a core set of principles. The Foundry now includes more than 150 ontologies. The Ontology Development Kit (ODK) [1] was developed to facilitate the implementation of standardized ontology development practices across the Foundry. It takes the form of a Docker image that provides ontology editors with all the command-line tools they need to manage, edit, build, and test their ontologies, as well as standardized and carefully crafted Makefile rules to pilot all steps of the ontology life cycle. In recent years, many ontologies such as the Uberon multi-species anatomy ontology, the Cell Ontology (CL), or the Unified Phenotype Ontology (uPheno) have been converted to use the ODK. By moving most of the management, building, and testing logic from the individual ontologies to the ODK, the kit aims to make the life of ontology editors easier, by allowing them to focus solely on actual ontology editing, all the while contributing to the standardisation of the various ontologies.</p> PUBLIC CONFIRMED Open Research Tools and Technologies https:/fosdem.org/2022/schedule/event/open_research_ontology_development_kit/ D.research Damien Goutte-Gattat PUBLISH 12891@FOSDEM22@pentabarf.org 12891 ada_outsiders_guide ada_outsiders_guide The Outsider's Guide to Ada Lessons from Learning Ada in 2021 en en_US Ada 2022-02-06 15:50:00 +0100 2022-02-06 16:25:00 +0100 00:35:00:00 20220206T155000 20220206T162500 00:35:00:00 The Outsider's Guide to Ada- Lessons from Learning Ada in 2021 <p>Ada can be difficult to approach due to using a different vernacular to most other languages, and also having many unfamiliar structures and ways of doing things.</p> <p>This is an overview of the Ada language by someone who is new to the language, for programmers from other languages, kept as neutral and objective as possible.

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

This lowers battery usage, improves latency and leaves the 3D engine free for clients to use. The display engines found in modern GPUs often can support this zero-copy mechanism only if the buffers have been allocated in a special fashion. However, buffers allocated this way won't be optimal for rendering, and only a handful of buffers can be directly displayed.</p> <p>As a result, a trade-off between zero-copy display and optimal rendering needs to be made. The compositor is the natural place where a decision can be made, because it has a global view of all apps which need to be presented. Once the compositor has taken a decision, it needs to be communicated to the clients. The brand new linux-dmabuf feedback protocol enables this negotiation between the compositor and the clients.</p> <p>If you're up for some window system integration madness, grab some popcorn and come enjoy the show!</p> PUBLIC CONFIRMED Graphics https:/fosdem.org/2022/schedule/event/dmabuffeedback/ D.graphics Simon Ser PUBLISH 12816@FOSDEM22@pentabarf.org 12816 collabcarbonio collabcarbonio How to overcome development challenges when building self-hosted collaboration platform Our experience with Carbonio Community Edition en en_US Collaboration and Content Management 2022-02-05 16:00:00 +0100 2022-02-05 16:30:00 +0100 00:30:00:00 20220205T160000 20220205T163000 00:30:00:00 How to overcome development challenges when building self-hosted collaboration platform- Our experience with Carbonio Community Edition <p>While the world is moving toward SaaS and Cloud infrastructures, many companies want to keep things in a self-hosted platform or in a private cloud.

There are multiple reasons for this increase of interest. First, the rise of big data analytics, high performance computing, machine learning workloads that need high-bandwidth and low latency and sometimes even requires access to special hardware devices like GPUs or DPUs. And at the same time, in the telecommunication space, the 5G networks technology stacks that drive the need for IPv6, SR-IOV, Container Network Functions (CNFs), NUMA topologies, and other innovations in containerized applications on bare metal.</p> <p>All of these emphasize the need for the ability to easily create Bare Metal based OpenShift clusters as automatically as possible.</p> <p>Central Infrastructure Management (CIM) exposes an intuitive user interface, allowing the infrastructure administrator to define a pool of Bare Metal machines making them available for users to independently create OpenShift clusters from them.</p> <p>Assisted Installer is an operator that introduces a new way to deploy a new OpenShift cluster on bare metal basically by only booting the nodes that will be part of the cluster, with an ISO it generates.

It aims to facilitate collaboration across various institutional and individual partners in order to ensure the continued development and long-term sustainability of Wikibase, a suite of tools for data management within a linked open data environment. Wikibase is currently developed and maintained by Wikimedia Germany, a chapter of the non-profit Wikimedia Foundation. Wikibase is vital infrastructure for the public linked data project Wikidata, but since its open release in 2015 it has been increasingly taken up in research, cultural and institutional contexts due to its flexible, open and collaborative architecture. Rhizome have been piloting the use of Wikibase within GLAM contexts since its release, and have co-organized the first set of public meetups and events around the emerging Wikibase community and ecosystem of decentralized Wikibase instances. Following the success in bringing the community together through these events Rhizome and a few early adopters started the Wikibase Stakeholder Group at the end of 2020.

Right now, it is a bootable system targeting a variety of CPU architectures (aarch64, ppc64le, riscv64, x86_64...) that is easily bootstrappable (and capable of building itself), testable, lightweight and fast (but still in heavy development).

It is a great opportunity to thank people for their work and highlight their contributions to the rest of the community. However, we need to evaluate if we’re truly being inclusive with our community recognitions. For example, when discussing contributors, we still see a lot of emphasis on the volume of contributions on project repositories (i.e., code) that some may find intimidating. This focus on code is partly because contributions on tools like GitHub and GitLab are easier to measure and quantify.</p> <p>On the other hand, it can be more challenging to measure (or even notice) how much a community member is helping others on platforms like Discord, Matrix, Slack, etc. When someone helps a newcomer by answering a quick question in chat, it’s easy to miss that among other discussion threads. Even though it can be more challenging to quantify non-code contributions, it’s crucial to look beyond repositories to see how people are helping to improve our communities. In addition to contributions in chat-like platforms, this can include sharing their use cases, participating in meetups, providing honest feedback in 1-on-1 conversations, etc. Looking across a broad spectrum of contributions will help ensure that we recognize everyone regardless of their background, interests, and skillset.</p> PUBLIC CONFIRMED Community https:/fosdem.org/2022/schedule/event/community_recognition/ M.community Ray Paik PUBLISH 12568@FOSDEM22@pentabarf.org 12568 go_json go_json JSON Serialization - The Fine Print A journey of JSON serialization en en_US Go 2022-02-05 16:15:00 +0100 2022-02-05 16:50:00 +0100 00:35:00:00 20220205T161500 20220205T165000 00:35:00:00 JSON Serialization - The Fine Print- A journey of JSON serialization <p>We'll look into JSON serialztion, starting from the easy cases and moving toward more advanced ones.</p> PUBLIC CONFIRMED Go https:/fosdem.org/2022/schedule/event/go_json/ D.go Miki Tebeka PUBLISH 12691@FOSDEM22@pentabarf.org 12691 vai_hardware_accel vai_hardware_accel Hardware-accelerated graphics in secure multi-tenant environments What is the current status, and what is blocking it? en en_US Virtualization and IaaS 2022-02-05 16:15:00 +0100 2022-02-05 17:15:00 +0100 01:00:00:00 20220205T161500 20220205T171500 01:00:00:00 Hardware-accelerated graphics in secure multi-tenant environments- What is the current status, and what is blocking it? <p>Hardware-accelerated graphics is becoming an essential part of modern computing environments, yet it is currently very difficult to impossible to use in secure environments such as Qubes OS.

When such a package adheres to semantic versioning, backports can be recognised as new releases in a lower major train. This is particularly useful in case a substantial number of software packages continues to depend on that lower major train. In this talk, we discuss the backporting practices in four popular package distributions, namely Cargo, npm, Packagist and RubyGems.

In particular, we find that a majority of security vulnerabilities affect more than one major train but are only fixed in the highest one, letting thousands of dependent packages exposed to the vulnerability.

The GNAT compiler implements this support in its runtime library, which comes in a number of different flavors, with more or less capability. The GNAT light runtime library is a version of the runtime library targeted at embedded platforms and certification, with an Operating System or without it (baremetal). It contains around 180 units focused mostly on I/O, numerics, text manipulation, memory operations.</p> <p>Variants of the GNAT light runtime library have been certified for use at the highest levels of criticality in several industrial domains: avionics (DO-178), space (ECSS-E-ST40C), railway (EN 50128), automotive (ISO-26262). Details vary across certification regimes, but the common approach to certification used today is based on written requirements traced to corresponding tests, supported by test coverage analysis. Despite this strict certification process, some bugs were found in the past in the code. An ongoing project at AdaCore is applying formal proof with SPARK to the light runtime units, in order to prove their correctness: that the code is free of runtime errors, and that it satisfies its functional specifications.</p> <p>So far, 30 units (out of 180) have been proved, and a few bugs fixed along the way (including a security vulnerability). In this talk, I will describe the approach followed, what was achieved, and what we expect to achieve.</p> PUBLIC CONFIRMED Ada https:/fosdem.org/2022/schedule/event/ada_proving_gnat_light_runtime/ D.ada Yannick Moy PUBLISH 12600@FOSDEM22@pentabarf.org 12600 commonworkflowlang commonworkflowlang Concise Common Workflow Language Concision and elegance in a workflow language using lisp en en_US Declarative and Minimalistic Computing 2022-02-06 16:25:00 +0100 2022-02-06 17:00:00 +0100 00:35:00:00 20220206T162500 20220206T170000 00:35:00:00 Concise Common Workflow Language- Concision and elegance in a workflow language using lisp <p>Scientific workflows are readily and most easily expressed as shell scripts. However, shell scripts are notorious for being "duct tape", and are hard to adapt to different hardware and software environments. Workflow languages such as the Common Workflow Language (CWL) were developed to address this pain point. However, CWL does come at the cost of increased verbosity and reduced readability. Even seasoned scientists shy away from writing CWL, and fall back to the familiarity of shell scripts.</p> <p>This need not be. There is no reason to inflict the behind-the-scenes complexity of workflow languages on the user. It should be possible to automatically translate (in other words, compile) a simple shell-like script into a workflow language specification. In effect, we create a new domain specific language that is almost as easy to write as a shell script, but compiles to CWL. No other language is better suited to this task of creating domain specific languages than lisp. The lisps with their homoiconicity and unique macro system empower the programmer to use ordinary code to hack the compiler itself.</p> <p>In this talk, I will present the Concise Common Workflow Language (ccwl). The Concise Common Workflow Language (ccwl) is a concise syntax to express CWL workflows. It is a compiler that compiles a simple lispy shell-like workflow specification into a CWL workflow. It is implemented in the Scheme programming language, a minimalist dialect of lisp. I will discuss the considerations that went into the design of ccwl, and demonstrate its expressive power with illustrative examples.</p> PUBLIC CONFIRMED Declarative and Minimalistic Computing https:/fosdem.org/2022/schedule/event/commonworkflowlang/ D.minimalistic Arun Isaac PUBLISH 12334@FOSDEM22@pentabarf.org 12334 venix venix A Venix/86 emulator A step in recreating Venix/86 Sources en en_US Emulator Development 2022-02-06 16:30:00 +0100 2022-02-06 17:15:00 +0100 00:45:00:00 20220206T163000 20220206T171500 00:45:00:00 A Venix/86 emulator- A step in recreating Venix/86 Sources <p>Venix/86 was the first commercially available Unix for the IBM PC. PC/IX was the first one that IBM supported, but VentureCom created released this port about the time PC/IX was announced. They ported it to a number of the 'near compatible' systems as well, so for many people the first Unix available on those early 8086/8088 machines was Venix. This included the DEC Rainbow 100B with Venix/86R.</p> <p>A companion project to recreate the sources for Venix/86 from 7th edition tapes now available was hampered by the slow speed of the DEC Rainbow, so I wrote the emulator to seed that along.</p> <p>This talk will be about the emulator's structure, system call interface and portability to other ancient 8088/8086 Unixes.

This provides significant new capabilities for multi-process abstractions such as mmap and fork, which will be beneficial for enclavizing legacy software.</p> <p>However, taking a VM image and running it in an enclave is not great from a TCB minimization standpoint. For platforms where there's currently no alternative (AMD, AWS), how can we build--with a minimal TCB--an abstraction that's similar to single-process enclaves? Of course you can “just run Linux” with a single process but this again is clearly suboptimal.

Nowadays, models with up to billions of parameters are trained for vast arrays of downstream tasks and obtain performance that defies what a lot considered possible 20 years ago. However, the reliance of machine learning models on the spurious correlations often prevents them from learning the intrinsic and invariant features of data, leading to their failure to generalize to Out-Of-Distribution (OOD) data. Understanding and overcoming these failures have led to a research program on OOD generalization.</p> <p>The field has been extensively explored in the static computer vision tasks (Domainbed, WILDS) but has been severely underexplored for time series tasks essential for multiple areas of applied machine learning, e.g., medical, finance, communication. We propose a set of new open source out-of-distribution generalization datasets for sequential prediction tasks spanning multiple modalities that act as benchmarks for potential algorithms that promote invariant learning. Along with the datasets, we provide a fair and systematic open-source platform for evaluating the performance of existing and potential algorithms on these datasets. We also provide a leaderboard that currently consists of popular algorithms' performance in the field of OOD generalization.</p> PUBLIC CONFIRMED HPC, Big Data, and Data Science https:/fosdem.org/2022/schedule/event/woods_ood_generalization_benchmarks/ D.hpc Jean-Christophe Gagnon-Audet PUBLISH 12487@FOSDEM22@pentabarf.org 12487 collabcsp collabcsp Deploying Containerised Open-Source CSP platforms Alfresco and Nuxeo in action! en en_US Collaboration and Content Management 2022-02-05 16:30:00 +0100 2022-02-05 17:30:00 +0100 01:00:00:00 20220205T163000 20220205T173000 01:00:00:00 Deploying Containerised Open-Source CSP platforms- Alfresco and Nuxeo in action! <p>Understand containerised deployment with Open-Source CSP (Content Service Provider) platforms.

In order to simplify application development, service mesh architectures have emerged as the evolutionary architectural paradigms for taking care of bulk of application communication logic such as health checks, circuit breaking, secure communication, resiliency (among others), thereby decoupling application logic with communication infrastructure. The latency to throughput ratio needs to be measurable for high performant deployments at the Edge. Providing benchmark data for various edge deployments with Bare Metal and virtual machine-based scenarios, this paper digs into architectural complexities of deploying service mesh at edge environment, performance impact across north-south and east-west communications in and out of a service mesh leveraging popular open-source service mesh Istio/Envoy using a simple on-prem Kubernetes cluster.

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

I took on the challenge to implement NTFS, the primary filesystem used by Windows, in a Rust crate that is equally usable from the firmware level up to user-mode.</p> <p>While Rust has been conquering the system software landscape for the past few years, there are next to no examples for implementing filesystems. Likewise, NTFS only has a single major open-source implementation known as ntfs-3g, and it was developed in C over a decade ago.</p> <p>This talk will cover my motivation for targeting NTFS and various use cases for such a Rust crate. I will introduce you to the internals of the NTFS filesystem, how they influenced the crate's design, and how Rust's features can be leveraged to create a safe and maintainable implementation. My talk will cover the current implementation, but also the necessary iterations until I got there. Finally, we will also deal with the current limitations of the Rust ecosystem and possible future improvements to the crate.</p> <p>You will see that Rust has many advantages for implementing filesystems, and I hope to see more such crates in the future.</p> PUBLIC CONFIRMED Miscellaneous https:/fosdem.org/2022/schedule/event/misc_ntfs_rust/ M.misc Colin Finck PUBLISH 12836@FOSDEM22@pentabarf.org 12836 tracking_software_dependencies tracking_software_dependencies Tracking Software Dependencies en en_US Software composition and dependency management 2022-02-06 17:00:00 +0100 2022-02-06 17:20:00 +0100 00:20:00:00 20220206T170000 20220206T172000 00:20:00:00 Tracking Software Dependencies <p>The accurate identification of software elements and their dependency relationships are critical for understand when specific software is exploitable.

Most importantly, we want to encourage people without strong computer science background to apply fundamental best practices, e.g., version control, from the start.

Starting from version control, the topics range to fully automated experiments using CI/CD workflows. Many of the existing examples concern OpenFOAM development due to the knowledge-base’s heritage in TU Darmstadt’s CRC 1194.

Our glossary helps by providing brief explanations of relevant terms used throughout the articles.

We envision “groupware” (like calendars, simple games, chat, collaborative docs, etc.) decoupled from reputation and group culture metrics (e.g. entry and exit rules, engagement incentives, likes or claps, visibility and feed ordering); in social platforms on the centralized web, these distinct functions are typically combined. To facilitate neighbourhoods, we are building a language and “interchange” for reputation data on Holochain such that users can connect a portable reputation extension to bundles of Holochain groupware.</p> <p>Groups can then use the neighbourhoods framework to bundle p2p modules with reputational and cultural inputs that relate to their particular use cases and style of relating. This also means individuals’ reputation and activity records are stored on their devices, and so can be ported to other neighbourhoods and verified using Holochain’s gossip protocol for data validation. Neighbourhoods is centered on the Holochain ecosystem, but it may also be of interest to dWeb communities and projects aspiring to traffic in “richer” data than ownership claims &amp; token counts - especially when those data support community collective intelligence.</p> <p>Much of the system remains to be built, but the core language - <code>rep_lang</code> - has been integrated with Holochain. We’ll close with a brief demo showing one key aspect of the system: <code>rep_lang</code> computations being validated by multiple agents on Holochain.</p> PUBLIC CONFIRMED Web3 Infrastructure https:/fosdem.org/2022/schedule/event/neighbourhoods/ D.web3 Emaline Friedman Michael Hueschen PUBLISH 13515@FOSDEM22@pentabarf.org 13515 plan_9_cpu_cmd plan_9_cpu_cmd Plan 9 CPU command, in Go, for Linux the network is the computer -- for real this time en en_US Open Source Firmware, BMC and Bootloader 2022-02-05 17:00:00 +0100 2022-02-05 17:50:00 +0100 00:50:00:00 20220205T170000 20220205T175000 00:50:00:00 Plan 9 CPU command, in Go, for Linux- the network is the computer -- for real this time <p>I have reimplemented the Plan 9 cpu command in pure Go, available at github.com/u-root/cpu.

Use the UI, the command line or an REST API to manage servers and desktop efficiently from a central place.</p> <p>RPort is a comprehensive solution for remote management of servers and desktop systems. Even if they are behind firewalls, routers and NAT. RPort is built on the client-server principle, clients connect to the server, the management component, using a secure reverse tunnel. Unlike pure SSH, RPort is made for heterogeneous environments (Windows, Linux, macOS) and addresses four basic needs of system administrators: • Secure remote access from anywhere via tunnels and SSH/RDP/VNC/HTTP and other TCP connections • Script and command execution on target machines via a central dashboard. • Automation of recurring tasks such as updates, inventory, configuration and fine-tuning of systems. • Monitoring and logging system load and resource usage.</p> <p>With RPort, a complete IT infrastructure with Windows, Linux and macOS systems can be managed via command line or a convenient web-based, central dashboard. The server component can be self-hosted or deployed in minutes using the automated installer provided by RPort. RPort is released under the MIT open-source license.</p> PUBLIC CONFIRMED Infra Management https:/fosdem.org/2022/schedule/event/rport_remote_access_management/ D.infra tkramm PUBLISH 13539@FOSDEM22@pentabarf.org 13539 openpowerfoundation openpowerfoundation OpenPOWER Foundation 2.0 en en_US OpenPOWER 2022-02-05 17:00:00 +0100 2022-02-05 18:00:00 +0100 01:00:00:00 20220205T170000 20220205T180000 01:00:00:00 OpenPOWER Foundation 2.0 <p>This is a presentation about the revamp of OpenPOWER platform by the OpenPOWER Foundation</p> PUBLIC CONFIRMED OpenPOWER https:/fosdem.org/2022/schedule/event/openpowerfoundation/ D.openpower James Kulina PUBLISH 12634@FOSDEM22@pentabarf.org 12634 mariadb_json mariadb_json Introducing MYSQL_JSON plugin en en_US MariaDB Server 2022-02-05 17:05:00 +0100 2022-02-05 17:35:00 +0100 00:30:00:00 20220205T170500 20220205T173500 00:30:00:00 Introducing MYSQL_JSON plugin <p>MYSQL_JSON plugin is created in MariaDB as a bridge to bypass the confusion between MySQL and MariaDB JSON data type representation and to help MariaDB users in that regard.

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

Such applications are composed of components referred to as micro services. With the increasing number of micro services, it becomes increasingly difficult to understand how all the components communicate.</p> <p>This is where Istio service mesh comes into play. Istio allows developers to manage and monitor network traffic between micro services and by providing features like mutual TLS, request retries or request circuit breaking. Vendoring these features from Istio helps keeping micro services focused on the actual application logic as they don't need to be implemented by the micro services. The IT industry has broadly adopted this architecture, but there are still plenty of legacy workloads running in virtual machines, which can't easily take the advantage of the features provided by service mesh. At least not until recently when KubeVirt introduced support for Istio service mesh.</p> <p>Attendees of this talk gain insight into the concept of the Istio sidecar proxy. A short demonstration showing typical use case of Istio service mesh -- canary deployment -- is presented. Next, this talk explains subtle differences of network traffic routing between regular Kubernetes pods and containerized KubeVirt virtual machines, leading to the challenges that these differences pose for traffic proxying. Finally, the changes necessary to support Istio for KubeVirt virtual machines are explained and the resulting functionality presented using the same scenario, but with the workload running in virtual machines instead of Kubernetes Pods.</p> <p>The takeaway of this talk is understanding of routing concepts behind Istio proxy sidecar with regular Kubernetes pods as well as with containerized KubeVirt virtual machines. Audience will have a chance to observe typical use case of Istio with both pods and virtual machines and get insight into the necessary changes that made this possible.</p> PUBLIC CONFIRMED Virtualization and IaaS https:/fosdem.org/2022/schedule/event/vai_tracing_kubevirt/ D.virtualization Radim Hrazdil PUBLISH 12797@FOSDEM22@pentabarf.org 12797 container_singularity_apptainer container_singularity_apptainer From Singularity to Apptainer en en_US Containers 2022-02-06 17:15:00 +0100 2022-02-06 17:45:00 +0100 00:30:00:00 20220206T171500 20220206T174500 00:30:00:00 From Singularity to Apptainer <p>Singularity, an open-source containerization platform built for high performance computing use cases and utilized by HPC sites all over the world, was recently moved into the Linux Foundation and renamed to "Apptainer."

We present our vision of "Open Cloud Services" that provide the same openness and freedom to users and developers as open-source software. But running a cloud service requires resources so how can that be funded? An ideal solution would be simple, equitable and fair -- and not compromise the ethos of open source. We'll discuss our attempt at solving this puzzle, a funding mechanism we call cloud funding. Next, we'll introduce Unfurl, our DevOps tool for building reproducible, cloud-provider independent open cloud services and then look to future Web3 and decentralization technologies that make this possible -- specifically how blockchain-based decentralized data and remote attestation, transparent and reproducible open cloud services, and next-generation secure-computing cloud infrastructure all combine to provide the building blocks of a free and open cloud.</p> PUBLIC CONFIRMED Web3 Infrastructure https:/fosdem.org/2022/schedule/event/onecommons/ D.web3 Adam Souzis PUBLISH 13122@FOSDEM22@pentabarf.org 13122 closing_public_code closing_public_code Closing of the Public Code devroom Reflections from the day en en_US Public Code 2022-02-06 17:30:00 +0100 2022-02-06 17:50:00 +0100 00:20:00:00 20220206T173000 20220206T175000 00:20:00:00 Closing of the Public Code devroom- Reflections from the day <p>Closing of the devroom with some reflections of what we have heard through the day.

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