We especially value the participation of youth in these projects, because they are the people which are affected by digitisation the most. Our educational concept is also based around the idea that young people should be judged by their abilities, not by age. They should learn to take responsibility and be independent. An example of this would be the AlekSIS project.

This was a deliberate tactical choice made by the OpenStack community years ago, forming a so called "Big Tent" for vendors to collaborate in to build Open Source cloud options. It made a lot of sense at the time to be honest. However, OpenStack today finds itself constrained by the large number of permutations it must support, ten years of software and backwards compatability legacy, and a decreasing investment from those same vendors that OpenStack courted so actively.</p> <p>OpenStack Compute wasn't always like this though. The first public git commit had about 5,000 lines of code in it, and was surprisingly functional. What would a simpler and more opinionated IaaS compute component look like? Especially if it could take advantage of the general improvement of Open Source tooling in the last decade that OpenStack has driven? This was what I was pondering in late 2019 as I started to drift away from the OpenStack community for various reasons. Then, a series of natural disasters in Australia and globally presented me with an opportunity to cancel all my extracurricular activities and really give an experiment a go. That experiment is called Shaken Fist (as in old man shakes fist at cloud), is about the same size as the original OpenStack Compute commit, and is available at https://shakenfist.com. I'd appreciate the opportunity to discuss some of the simplifying assumptions made, what functionality is available, whether the experiment tells us anything interesting, and possible future directions.</p> PUBLIC CONFIRMED Cloud Computing https:/fosdem.org/2021/schedule/event/cloud_shaken_fist/ M.misc Michael Still PUBLISH 10853@FOSDEM21@pentabarf.org 10853 perl_raku_welcome perl_raku_welcome Welcome to the Perl & Raku devroom Introduction, lineup, CoC, AoB en en_US Perl and Raku Programming 2021-02-06 10:00:00 +0100 2021-02-06 10:15:00 +0100 00:15:00:00 20210206T100000 20210206T101500 00:15:00:00 Welcome to the Perl & Raku devroom- Introduction, lineup, CoC, AoB <p>A brief introduction to the 2021 virtual FOSDEM devroom, talk overview, code of conduct and Community Affairs Team.</p> <p>Please ask any questions after the introduction - there will be 10 minutes for discussion.</p> <p>TPF Code of Conduct applies to our devroom</p> PUBLIC CONFIRMED Perl and Raku Programming https:/fosdem.org/2021/schedule/event/perl_raku_welcome/ D.perl Juan Julián Merelo Stuart J Mackintosh PUBLISH 10909@FOSDEM21@pentabarf.org 10909 community_devroom_abracadabra_everyones_remote community_devroom_abracadabra_everyones_remote Abracadabra, now everyone's a remotee! en en_US Community devroom 2021-02-07 10:00:00 +0100 2021-02-07 10:30:00 +0100 00:30:00:00 20210207T100000 20210207T103000 00:30:00:00 Abracadabra, now everyone's a remotee! <p>Management is difficult even under the best of circumstances and managing globally-distributed teams is even more so.

More than ever companies choose FOSS, however the world of safety is behind the curve. Software developed for safety applications often use old development practices and are closed source. Too commonly this code is seen as a competitive advantage, and having spent vast sums developing and analysing for safety, companies are reluctant to share their code. Ultimately this is to the detriment of everyone, and leaves us all vulnerable to unsafe software.</p> <p>This talk will outline the problems with software in safety currently, detail how using FOSS practices could benefit not just the wider community but the leading industry suppliers, and talk about what we need to do as FOSS creators to convince industry that this is the way forward and make the software we use safer for all.</p> PUBLIC CONFIRMED Safety and Open Source https:/fosdem.org/2021/schedule/event/safety_opensource_foss_safety/ D.safety PUBLISH 11860@FOSDEM21@pentabarf.org 11860 monitoring_observability_intro monitoring_observability_intro Monitoring & Observability intro en en_US Monitoring and Observability 2021-02-07 10:00:00 +0100 2021-02-07 10:15:00 +0100 00:15:00:00 20210207T100000 20210207T101500 00:15:00:00 Monitoring & Observability intro <p>Our customary welcome.</p> PUBLIC CONFIRMED Monitoring and Observability https:/fosdem.org/2021/schedule/event/monitoring_observability_intro/ D.monitoring Richard Hartmann PUBLISH 12283@FOSDEM21@pentabarf.org 12283 ow2_telosys ow2_telosys Hey, developers, stop writing repetitive code, let Telosys do it for you! en en_US OW2 Open Source Community stand 2021-02-06 10:00:00 +0100 2021-02-06 11:00:00 +0100 01:00:00:00 20210206T100000 20210206T110000 01:00:00:00 Hey, developers, stop writing repetitive code, let Telosys do it for you! <p>Presentation of OW2 Telosys project</p> PUBLIC CONFIRMED OW2 Open Source Community stand https:/fosdem.org/2021/schedule/event/ow2_telosys/ S.ow2 PUBLISH 12289@FOSDEM21@pentabarf.org 12289 checkmk_askusanything2 checkmk_askusanything2 Ask-us-Anything Ask us about anything IT monitoring en en_US Checkmk stand 2021-02-06 10:00:00 +0100 2021-02-06 10:45:00 +0100 00:45:00:00 20210206T100000 20210206T104500 00:45:00:00 Ask-us-Anything- Ask us about anything IT monitoring PUBLIC CONFIRMED Checkmk stand https:/fosdem.org/2021/schedule/event/checkmk_askusanything2/ S.checkmk PUBLISH 12315@FOSDEM21@pentabarf.org 12315 ow2_mrl_2 ow2_mrl_2 OW2 Market Readiness Levels and OSS long-term sustainibility en en_US OW2 Open Source Community stand 2021-02-07 10:00:00 +0100 2021-02-07 10:30:00 +0100 00:30:00:00 20210207T100000 20210207T103000 00:30:00:00 OW2 Market Readiness Levels and OSS long-term sustainibility <p>Presentation of OW2 MRL : Market Readiness Levels.</p> PUBLIC CONFIRMED OW2 Open Source Community stand https:/fosdem.org/2021/schedule/event/ow2_mrl_2/ S.ow2 PUBLISH 10974@FOSDEM21@pentabarf.org 10974 nemoopennms nemoopennms What's new with OpenNMS Technology and roadmap update en en_US Network monitoring, discovery and inventory 2021-02-06 10:05:00 +0100 2021-02-06 10:50:00 +0100 00:45:00:00 20210206T100500 20210206T105000 00:45:00:00 What's new with OpenNMS- Technology and roadmap update <p>In March 2021, OpenNMS will celebrate its twenty-first year as a free software project.

Veracruz uses Arm TrustZone, Intel SGX, AWS Nitro Enclaves, or the high-assurance seL4 microvisor, to provide a "neutral ground" within which a collaborative computation takes place, shielded from prying or interference by the host of the computation. The computation itself is realised by a WebAssembly program which sandboxes the computation, means Veracruz programs are portable across different isolation technologies, and allows multi-party computations to be quickly written in high-level programming languages with standard development tools. Potential use-cases for Veracruz include support for privacy-preserving collaborative machine-learning, privacy-preserving surveys, polls, elections, or auctions, and safely delegating computations from weak devices to more powerful devices, amongst many others.</p> PUBLIC CONFIRMED Hardware-Aided Trusted Computing https:/fosdem.org/2021/schedule/event/tee_veracruz/ D.hardware.trusted Dominic Mulligan PUBLISH 10970@FOSDEM21@pentabarf.org 10970 monarch_open_source_reimplementation monarch_open_source_reimplementation A Google Monitoring System, Monarch… in Open Source? en en_US Monitoring and Observability 2021-02-07 10:30:00 +0100 2021-02-07 11:00:00 +0100 00:30:00:00 20210207T103000 20210207T110000 00:30:00:00 A Google Monitoring System, Monarch… in Open Source? <p>Recently Google published a paper on their monitoring system Monarch, which happened to have similar design choices to the existing CNCF Incubated project: Thanos!

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

Unlike other tracing backends Tempo can hit massive scale without a massive and difficult to manage Elasticsearch or Cassandra cluster.

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

Furthermore, recently added BPF redirection helpers are discussed which offer a low-latency switch into Pod network namespaces.

In multi-party settings in which the parties may not always fully trust each other, attestation of multiple pieces of code or data images via these means is cumbersome and inefficient. For example, consider the case of a secure cloud service running a JavaScript interpreter, which interprets a third-party script, in which case both, the interpreter and the script, can interfere with each other's attestation evidence as they share an address space. Similarly, a group of users may want to compute a shared result over all of their combined data, but without sharing their data with each other. Attestation in such scenarios is greatly simplified by a technique called Extended Enclave Initialization Data (EEID), which provides a secure and convenient means to combine all required attestation evidence, and to automatically re-sign images (with a well known service key) during enclave startup to ensure that all of the code and data is loaded and attested appropriately. An added benefit is that even single-party applications can use this technique to automatically re-sign enclave images with modified configuration settings (like memory size and thread count), independent of, or in addition to, underlying TEE support for configuration changes. EEID is currently available as an experimental feature for SGX enclaves in the Open Enclave SDK and it is used in multiple prototype services at Microsoft.</p> PUBLIC CONFIRMED Hardware-Aided Trusted Computing https:/fosdem.org/2021/schedule/event/tee_oe/ D.hardware.trusted Christoph M.

However, most people use these tools in temporary scripts for a one-time tweets collection. Moving to a robust application for collecting and indexing tweets over long periods of time requires some programming knowledge that most social science researchers do not master. In order to meet this need, the medialab has developed gazouilloire, a tool that makes it possible to easily configure the collection parameters (keywords searched, language of tweets, location of tweets, etc.) and can then be launched from the command line.</p> <p>Gazouilloire combines two methods to collect tweets from the Twitter API ("search" and "filter") in order to maximize the number of collected tweets, and automatically fills the gaps in the collection in case of connexion errors or reboots. It also provides a large range of features that are not directly available from the free Twitter API: collecting during specific periods of time, resolving redirected urls, downloading only certain types of media contents (only photos and no videos, for example) or unfolding Twitter conversations. The user can then choose to export the tweets in csv format, and select the fields that will form the columns of the table.</p> <p>Social science researchers have already used gazouilloire for a wide variety of studies: measuring online activity during COVID-19 lockdown, studying the public discourse of anti-vaxxers, or monitoring urban nature policies, among many others...</p> PUBLIC CONFIRMED Open Research Tools and Technologies https:/fosdem.org/2021/schedule/event/open_research_gazouilloire/ D.research Béatrice Mazoyer PUBLISH 11169@FOSDEM21@pentabarf.org 11169 realtime_netlisting realtime_netlisting Real-time Netlisting in KiCad Motivation, Implementation, and Benefits en en_US Open Source Computer Aided Modeling and Design 2021-02-07 11:25:00 +0100 2021-02-07 11:50:00 +0100 00:25:00:00 20210207T112500 20210207T115000 00:25:00:00 Real-time Netlisting in KiCad- Motivation, Implementation, and Benefits <p>KiCad 6 features a new real-time netlisting system that is used to determine connectivity between items in schematics as the user draws them.

In addition to this, empirical evidence has shown that these package managers adhere to a large extent to semantic versioning principles. Packages that are still in major version zero are considered unstable according to semantic versioning, as some developers consider such packages as immature, still being under initial development.</p> <p>This presentation reports on large-scale empirical evidence on the use of dependencies towards 0.y.z versions in four different software package distributions: Cargo, npm, Packagist and RubyGems. We study to which extent packages get stuck in the zero version space, never crossing the psychological barrier of major version zero.

The tool first identifies computational units which, in our terminology, are the atoms of parallelization. Then, it profiles memory accesses inside the source code to detect data dependencies. Mapping dependencies to CUs, we create a data structure which we call the program execution tree (PET). Further, DiscoPoP inspects the pet of a program to find parallel design patterns and parallelization suggestions in terms of OpenMP constructs and clauses. By far, DiscoPoP detects doall, reduction, pipeline, task parallelism, and geometric decomposition in a program.</p> <p>We used DiscoPoP to create OpenMP versions of 49 sequential benchmarks and compared them with the code produced by three state-of-the-art parallelization tools: Our codes are faster in most cases with average speedups relative to any of the three ranging from 1.8 to 2.7. Moreover, we analyzed the LULESH program and an astrophysics simulation code with DiscoPoP. In LULESH, we identify most of the parallelization opportunities which have been parallelized by expert programmers manually. In the astrophysics code, DiscoPoP finds unexploited parallelism opportunities and achieves a speed-up of up to 35%.</p> <p>DiscoPoP is released as an open source software and can be downloaded from:</p> <p>https://github.com/discopop-project/discopop</p> PUBLIC CONFIRMED HPC, Big Data and Data Science https:/fosdem.org/2021/schedule/event/discopop/ D.hpc Mohammad Norouzi PUBLISH 11021@FOSDEM21@pentabarf.org 11021 postgresql_database_schema_management_for_lazybones_from_chaos_to_heaven postgresql_database_schema_management_for_lazybones_from_chaos_to_heaven Database schema management for lazybones: from chaos to heaven en en_US PostgreSQL 2021-02-06 11:30:00 +0100 2021-02-06 12:30:00 +0100 01:00:00:00 20210206T113000 20210206T123000 01:00:00:00 Database schema management for lazybones: from chaos to heaven <p>Performing schema changes on a live system is challenging because it often involves high level of locks leading to downtime.

One can create their own types, operators, access methods, etc. or use powerful PL/pgSQL language to write functions, extensions, and so on and so on.

Common assertions such as “the use of CRISPR technologies has skyrocketed in laboratories all around the world since 2012” can now be easily verified in both quantitative and qualitative perspectives using those platforms. Such services as Elsevier’s Scopus propose inbuilt functions to explore corpuses chronologically and geographically. They don’t, however, allow for hand curation and enrichment of the corpus. This lecture advocates for a solution to this methodological issue using PANDORÆ, a free and open source software designed for that purpose. PANDORÆ requests corpuses from the Scopus API, enriches its data by geolocating each document’s affiliations, and then uploads the resulting dataset to a Zotero library. The user is then free to curate the corpus, adding, editing or removing items. PANDORÆ allows downloading it back from Zotero to its internal databases, and to display the enriched corpuses on a map, on a timeline, or as an author-directed force-layout network graph.</p> <p>This presentation will also introduce more advanced PANDORAE features, such as displaying Twitter dataset obtained through Gazouilloire, mapping web entities loaded from Hyphe and scraping biorXiv results using Artoo.</p> PUBLIC CONFIRMED Open Research Tools and Technologies https:/fosdem.org/2021/schedule/event/open_research_pandorae_tool/ D.research Guillaume Levrier PUBLISH 11531@FOSDEM21@pentabarf.org 11531 mariadb_buildbot_the_journey_of_a_reinvention mariadb_buildbot_the_journey_of_a_reinvention MariaDB Buildbot, the journey of a reinvention en en_US Continuous Integration and Continuous Deployment 2021-02-07 11:35:00 +0100 2021-02-07 11:55:00 +0100 00:20:00:00 20210207T113500 20210207T115500 00:20:00:00 MariaDB Buildbot, the journey of a reinvention <p>Recently, the MariaDB Foundation has been developing a new continuous integration framework for the MariaDB Server.

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

The key feature that it supports is that any survey is linked to an organizational unit that is part of a canonical hierarchy. Each one of these org. units can have a location and a territory. The mobile data collection tool can be used to enrich this hierarchy with additional GPS coordinates, names corrections, etc ... which can then be validated by officials of the organizations in question through the web dashboard. This leads to continuous improvements of the geographic references available through the routine activities already planned (e.g. locating and registering health facilities while investigating malaria cases).</p> <p>The tool has been used in multiple data collection efforts, notably in the domain of Performance Based Financing of health services in D.R. Congo, Niger, Cameroon and Nigeria and is more and more used to compare multiple versions of official organisational hierarchies when a canonical one needs to be rebuilt.

Spaces: The Final Frontier! <p>Matrix (https://matrix.org) is an open protocol for secure, decentralised communication - defining an end-to-end-encrypted real-time communication layer for the open Web suitable for instant messaging, VoIP, microblogging, forums and more. We provide the open standard and open source tools to democratise communication away from the proprietary closed communication silos (Slack, Discord, Telegram, WhatsApp etc) that currently dominate.</p> <p>In this talk, we'll explain all the features we've been adding to let Matrix scale to support massive virtual communities such as FOSDEM itself, Mozilla, KDE and others. This includes Spaces: the ability to group rooms into a hierarchy, for ease of discovery and management; Widgets: the ability to add arbitrary webapps to chatrooms to provide dashboards of additional functionality (e.g. the FOSDEM livestreams and video conferences); Threading: the ability (at last!) to support threaded conversations in Matrix; and Decentralised Reputation - the ability to empower users to tune out content they dislike on their own terms. Our goal is to ensure no open source project ever uses Slack/Discord/Telegram to collaborate ever again.

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

A feature called "Merge Confidence" helps downstream users know if a release is likely good or not based on automatically sourced crowd data (tests, deployments, rollbacks). Now we are planning to turn the focus upstream to help open source maintainers get an early indication of accidentally breaking releases and even provide a mechanism for downstream users to opt into silent pre-release testing so that major features can be smoke tested downstream before release.</p> PUBLIC CONFIRMED Dependency Management https:/fosdem.org/2021/schedule/event/dep_early_warning_signs_for_open_source_breakages/ D.dependency Rhys Arkins PUBLISH 11129@FOSDEM21@pentabarf.org 11129 open_source_under_attack open_source_under_attack The Death of Openness and Freedom?

For years vendors have been slowly chipping away at the freedom and openness provided by open source, this year saw unprecedented changes to how people view and value OSS. From licensing changes to as a service exclusive, what was open is no longer. Is this being driven solely by the cloud? or is this purely corporate greed and others viewing open Source as a successful business model to replicate?

Part of this discussion relates to how the new paradigm incorporates support for accessing accelerators, e.g. GPUs, FPGAs. That kind of support has been made available to traditional programming models the last couple of decades and its tooling has evolved to be stable and standardized (eg. CUDA, OpenCL/OpenACC, Tensorflow etc.).</p> <p>On the other hand, what does it mean for a highly distributed application instance (i.e. a Serverless deployment) to access an accelerator? Should the function invoked to classify an image, for instance, link against the whole acceleration runtime and program the hardware device itself? It seems quite counter-intuitive to create such bloated functions.</p> <p>Things get more complicated when we consider the low-level layers of the service architecture. To ensure user and data isolation, infrastructure providers employ virtualization techniques. However, generic hardware accelerators are not designed to be shared by multiple untrusted tenants. Current solutions (device passthrough, API-remoting) impose inflexible setups, present security trade-offs and add significant performance overheads.</p> <p>To this end, we introduce vAccel, a lightweight framework to expose hardware acceleration functionality to VM tenants. Our framework is based on a thin runtime system, vAccelRT, which is, essentially, an acceleration API: it offers support for a set of operators that use generic hardware acceleration frameworks to increase performance, such as machine learning and linear algebra operators. vAccelRT abstracts away any hardware/vendor-specific code by employing a modular design where backends implement bindings for popular acceleration frameworks and the frontend exposes a function prototype for each available acceleration function. On top of that, using an optimized paravirtual interface, vAccelRT is exposed to a VM’s user-space, where applications can benefit from hardware acceleration via a simple function call.</p> <p>In this talk we present the design and implementation of vAccel on two KVM VMMs: QEMU and AWS Firecracker. We go through a brief design description and focus on the key aspects of enabling hardware acceleration for machine learning inference for ligthweight VMs both on x86_64 and aarch64 architectures. Our current implementation supports jetson-inference &amp; TensorRT, as well as Google Coral TPU, while facilitating integration with NVIDIA GPUs (CUDA) and Intel Iris GPUs (OpenCL).</p> <p>Finally, we present a demo of vAccel in action, using a containerized environment to simplify configuration &amp; deployment</p> <ul> <li>[1] https://blog.cloudkernels.net/posts/vaccel</li> <li>[2] https://blog.cloudkernels.net/posts/vaccel_v2</li> <li>[3] https://vaccel.org</li> <li>[4] https://github.com/nubificus/docker-jetson-inference</li> </ul> PUBLIC CONFIRMED Virtualization and IaaS https:/fosdem.org/2021/schedule/event/vai_ml_lightweight_vmms/ D.virtualization Anastassios Nanos Babis Chalios PUBLISH 11760@FOSDEM21@pentabarf.org 11760 switchtoopenpowerhardware switchtoopenpowerhardware It's the right time to switch computing to Open Hardware Power Architecture en en_US OpenPOWER 2021-02-06 12:15:00 +0100 2021-02-06 13:00:00 +0100 00:45:00:00 20210206T121500 20210206T130000 00:45:00:00 It's the right time to switch computing to Open Hardware Power Architecture <p>The game has changed, FOSS OS and software is everywhere running on every CPU architectures and devices.

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

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

Consequently, using Terraform to maintain Kubernetes clusters and resources is a very common use-case. And it requires careful integration of many moving parts, from Terraform providers and modules, to CI/CD pipelines and triggers.</p> <p>However, despite this being such a popular use-case, teams previously had no alternative than writing everything from scratch. On the software development side we use frameworks to avoid reinventing the wheel for similarly common use-cases. But for the less mature infrastructure as code ecosystem use-case specific frameworks are a new concept.</p> <p>This talk will introduce Kubestack. An open-source framework for Terraform, that brings the developer experience of frameworks from application development to infrastructure as code.

GNU Emacs as a long history, and is still widely used and supported by a very active community of users and developers. A very popular feature of GNU Emacs is Org-mode which, at its core, offers a markup language similar to Markdown.</p> <p>Following a brief introduction to Org-mode, this presentation demonstrates its use for reproducible research: straightforward mixing of prose and code, execution of code blocks as well as display of the results. With Org-mode, GNU Emacs is turned into a computational notebook which functionalities goes well beyond popular alternatives such as Jupyter. Code blocks are not restricted to a particular programming language and data can be passed between them: generate data in C, analyse it in Python, visualise it with R, all in one single executable document. Moreover, Org-mode documents are nothing but plain text, making them inherently portable, sustainable, and suited to version control - crucial qualities for academic research. Moving on, I illustrate the export of Org-mode documents to richer formats: PDF, ODT, HTML and many more - all from within GNU Emacs. Lastly, I broaden the scope of this presentation and discuss the open nature of GNU Emacs itself. Indeed, GNU Emacs is free (as in freedom) software under a copyleft license. This ensures that GNU Emacs remains sustainable, community-owned software: GNU Emacs will never be "discontinued" or its features reduced inside a "community edition".</p> PUBLIC CONFIRMED Open Research Tools and Technologies https:/fosdem.org/2021/schedule/event/open_research_emacs_orgmode/ D.research Thibault Lestang PUBLISH 11146@FOSDEM21@pentabarf.org 11146 dep_as_strong_as_the_weakest_link dep_as_strong_as_the_weakest_link As Strong as the Weakest Link Securing the Software Supply Chain en en_US Dependency Management 2021-02-07 12:45:00 +0100 2021-02-07 13:25:00 +0100 00:40:00:00 20210207T124500 20210207T132500 00:40:00:00 As Strong as the Weakest Link- Securing the Software Supply Chain <p>The Solarwinds breach at the end of 2020 is an event that we won't truly understand the breadth and depth of for some time - if ever.

Aligned with the grand trends towards heterogeneous and near-data computing, computational storage has gained tremendous momentum and led to an on-going industry-wide effort on expanding the NVMe standard to support CSD. The first generation CSD products have built-in transparent compression, which can be deployed into existing computing infrastructure without any changes to the OS and applications. This proposed talk will discuss and present: (1) brief introduction to commercially available CSDs with built-in transparent compression, (2) experimental results that show, by replacing leading-edge normal SSD with CSD, one could reduce the storage cost by over 50% and meanwhile achieve 30% better Postgres TPS performance, and (3) experimental results that show CSD could meanwhile significantly reduce the Postgres write amplification, which enables the use of emerging low-cost QLC flash memory to further reduce the system storage cost. Finally, this proposed talk will discuss the potential of leveraging CSDs to improve the efficiency of important operations in Postgres.</p> PUBLIC CONFIRMED Performance https:/fosdem.org/2021/schedule/event/computational_storage/ M.misc Tong Zhang PUBLISH 11102@FOSDEM21@pentabarf.org 11102 sdn_fastclick sdn_fastclick FastClick and Beyond: A Look at High-Speed Software Dataplanes and Their Upcoming Challenges Click here to build your 100-Gbps router, load-balancer, firewall, NAT, DPI, and more! en en_US Software Defined Networking 2021-02-07 13:00:00 +0100 2021-02-07 13:20:00 +0100 00:20:00:00 20210207T130000 20210207T132000 00:20:00:00 FastClick and Beyond: A Look at High-Speed Software Dataplanes and Their Upcoming Challenges- Click here to build your 100-Gbps router, load-balancer, firewall, NAT, DPI, and more! <p>In this talk, we first show how to prototype high-speed network functions with FastClick, an open-source packet processing framework, which comes with hundreds of pre-built building blocks and leverages DPDK or Netmap to build 100-Gbps-capable firewalls, load-balancers, NATs, or IDSes.</p> <p>We then review the history of high-speed software dataplanes. We explain the evolution of graph-based (software) network packet processing from the early 2000s with the emergence of the Click Modular Router, and continue up to today's ecosystem, where many similar systems, such as VPP, BESS, and FastClick, coexist. We analyze the upcoming challenges to process packets at multi-hundred-gigabit-per-second rates. We argue that multi-hundred-gigabit networks should prevent performing memory accesses, as the interarrival time of packets is shrinking to a few nanoseconds, i.e., smaller than L3 cache access time. For instance, a 100-Gbps NIC could receive a minimal-sized frame every 6.72ns while operating at its maximum rate.</p> <p>To address these challenges, we propose PacketMill, our latest work, where we discuss other efforts/optimizations required to improve the performance of packet processing. PacketMill's ideas are directly applied to FastClick, so it comes for free. More specifically, we develop/use a better integration of DPDK to minimize the memory footprint of the high-speed software dataplanes. Furthermore, we propose a pipeline to reduce the number of instructions required for processing packets by using new data structures directly derived from the graph of network functions and compiler optimization techniques.</p> PUBLIC CONFIRMED Software Defined Networking https:/fosdem.org/2021/schedule/event/sdn_fastclick/ D.sdn Tom Barbette Alireza Farshin PUBLISH 11132@FOSDEM21@pentabarf.org 11132 openchain_overview openchain_overview Openchain overview updates and information on the OpenChain project en en_US OpenChain 2021-02-06 13:00:00 +0100 2021-02-06 13:10:00 +0100 00:10:00:00 20210206T130000 20210206T131000 00:10:00:00 Openchain overview- updates and information on the OpenChain project <p>A short overview of the OpenChain project, its purpose, goals and the current state</p> PUBLIC CONFIRMED OpenChain https:/fosdem.org/2021/schedule/event/openchain_overview/ D.openchain Jan Thielscher PUBLISH 11207@FOSDEM21@pentabarf.org 11207 performance_analysis_troubleshooting performance_analysis_troubleshooting Performance Analysis and Troubleshooting Methodologies for Databases en en_US Monitoring and Observability 2021-02-07 13:00:00 +0100 2021-02-07 13:30:00 +0100 00:30:00:00 20210207T130000 20210207T133000 00:30:00:00 Performance Analysis and Troubleshooting Methodologies for Databases <p>Have you heard about the USE Method (Utilization - Saturation - Errors), RED (Rate - Errors - Duration) or Golden Signals (Latency - Traffic - Errors - Saturations)?

There are several reasons for this, such as many viewing documentation as a separate product from code or a belief that people will be able to make sense of what the code is doing by reading the code.</p> <p>For these and other reasons, documentation work is often done at the last minute and done by people with low motivation and minimum effort. So the quality of the output will naturally suffer. These issues can be addressed by ensuring that documentation is everyone’s responsibility and that documentation is a core part of the product created using the same development and community processes. Besides, documentation is often an entry point for new community members and is a great place for early contributions. When everyone in the community is actively engaged in documentation--e.g., reviewing documentation fixes--it can help provide a valuable onboarding experience for new community members.</p> <p>In this session, the speakers will share their experience in documentation from both foundation-based open source projects and open source software companies. There will be a discussion on how community contributions for documentation can be encouraged and how community members can apply their learnings from documentation to other areas of open source communities. </p> PUBLIC CONFIRMED Community devroom https:/fosdem.org/2021/schedule/event/community_devroom_documentation_first_class_citizen/ D.community Ray Paik Sofia Wallin PUBLISH 11172@FOSDEM21@pentabarf.org 11172 sdn_terabit_csit sdn_terabit_csit Born Ready for Secure Terabit Internet!

Projects involve data collected with dozens of different instruments on dozens of different samples that are related to eachother in a hierarchical fashion. For each new project, researchers struggle with questions like: how should I organize my files and data? How should I name my samples? How should I keep track of the links between data and samples? Since no standard answer to these questions has been formulated, labs and individuals just improvise. The result is that most data and samples become utterly useless once the person who conducted the research leaves; no one else can find their way through the ad-hoc naming conventions and various excel sheets. This eventually translates into a lot of wasted and repeated efforts.</p> <p>The biological sciences have long ago figured out solutions to these problems, and they are lab information systems (LIMS) and digital lab notebooks. In this talk I will present how I organize my research workflow in eLabFTW, a free and open source lab notebook with some LIMS capabilities.

Major Linux distributions package software from a wide range of languages, but they restrict the versions you can install, and they make deep assumptions about compilers and runtime libraries to keep everything compatible. If you need a newer libc or a newer Python than the OS offers, you're often on your own. Python packaging supports native libraries, but it imposes strict rules on package builders to ensure that the binaries work in many places. Some packagers break the rules, e.g., TensorFlow binary packages (wheels) will only work on Ubuntu, frustrating users of other distributions. Containers provide some hope, but only if you stay inside their sandbox. If you your container to talk to a fast network or a GPU, you'll need to ensure binary compatibility between the container and the host OS. Is every ecosystem a walled garden or can we make it easier to bridge the gap?</p> <p>This talk takes a deeper look at the Application Binary Interface (ABI) and its place at the heart of nearly every software ecosystem. We'll look at the assumptions made by modern dependency management systems about toolchains and ABI. Most tools assume that toolchains and ABI are fixed, making it hard to take a package from one ecosystem and transplant it in another. We'll talk about how we can build dependency managers that can <em>reason</em> better about ABI compatibility, making decisions not just about which software versions to install but also about how those software versions should be built. We'll look at the types of metadata that need to be managed to enable a more flexible software environment, and how it affects the complexity of dependency resolution. Finally, we'll look at how some of these issues are being addressed in Spack, an open source package manager for high performance computing applications, which can span multiple languages, compilers, platforms, and software stacks.</p> PUBLIC CONFIRMED Dependency Management https:/fosdem.org/2021/schedule/event/dep_reusing_dependencies_across_ecosystems/ D.dependency Todd Gamblin PUBLISH 11515@FOSDEM21@pentabarf.org 11515 kuberig_kubernetes_without_yaml kuberig_kubernetes_without_yaml Kuberig, Kubernetes without the YAML burn-out! en en_US Continuous Integration and Continuous Deployment 2021-02-07 13:25:00 +0100 2021-02-07 13:45:00 +0100 00:20:00:00 20210207T132500 20210207T134500 00:20:00:00 Kuberig, Kubernetes without the YAML burn-out! <p>The Kubernetes tooling landscape is littered with template based solutions to deal with all the YAML needed to get things done.

We describe the frontend/backend driver port, the runtime needed to support the actual execution on the hardware and showcase our results in a brief demo of two unikernel frameworks performing ML inference on images.</p> PUBLIC CONFIRMED Microkernel https:/fosdem.org/2021/schedule/event/microkernel_hardware_acceleration_for_unikernels/ D.microkernel Charalampos Mainas PUBLISH 11666@FOSDEM21@pentabarf.org 11666 zig_intro zig_intro Welcome to the Zig Programming Language en en_US Zig Programming Language 2021-02-06 13:45:00 +0100 2021-02-06 14:45:00 +0100 01:00:00:00 20210206T134500 20210206T144500 01:00:00:00 Welcome to the Zig Programming Language <p>An introduction to the Zig programming language and the talks that will follow.</p> PUBLIC CONFIRMED Zig Programming Language https:/fosdem.org/2021/schedule/event/zig_intro/ D.zig Loris Cro PUBLISH 12291@FOSDEM21@pentabarf.org 12291 checkmk_askusanything3 checkmk_askusanything3 Ask-us-Anything Ask us about anything IT monitoring en en_US Checkmk stand 2021-02-06 13:45:00 +0100 2021-02-06 16:45:00 +0100 03:00:00:00 20210206T134500 20210206T164500 03:00:00:00 Ask-us-Anything- Ask us about anything IT monitoring PUBLIC CONFIRMED Checkmk stand https:/fosdem.org/2021/schedule/event/checkmk_askusanything3/ S.checkmk Checkmk Team PUBLISH 10842@FOSDEM21@pentabarf.org 10842 nemonaemon nemonaemon Monitoring Large Networks with Naemon, Thruk, Mod-Gearman and LMD challenges in distributed monitoring at global scale. en en_US Network monitoring, discovery and inventory 2021-02-06 13:50:00 +0100 2021-02-06 14:35:00 +0100 00:45:00:00 20210206T135000 20210206T143500 00:45:00:00 Monitoring Large Networks with Naemon, Thruk, Mod-Gearman and LMD- challenges in distributed monitoring at global scale. <p>An introduction to techniques required to scale Naemon like Thruk, Mod-Gearman and LMD.</p> PUBLIC CONFIRMED Network monitoring, discovery and inventory https:/fosdem.org/2021/schedule/event/nemonaemon/ D.network Sven Nierlein PUBLISH 10860@FOSDEM21@pentabarf.org 10860 community_devroom_mental_health_free_software community_devroom_mental_health_free_software Mental health and free software What I wish I’d been told before I got into free software, and more en en_US Community devroom 2021-02-07 13:50:00 +0100 2021-02-07 14:30:00 +0100 00:40:00:00 20210207T135000 20210207T143000 00:40:00:00 Mental health and free software- What I wish I’d been told before I got into free software, and more <p>Mental health is becoming a bigger and bigger focus, and this rise in awareness picked up even more speed with the current health crisis.

Performance-critical workloads like these require topology information in order to use co-located CPU cores and devices. Despite the success of Topology Manager, aligning topology of requested resources, the current native scheduler does not select a node based on it. It's time to solve this problem! We will introduce the audience to hardware topology, the current state of Topology Manager, gaps in the current scheduling process, and prior out-of-tree solutions. We'll explain the workarounds available right now: custom schedulers, creating scheduling extensions, using node selectors, or manually assigning resources semi-automatically. All these methods have their drawbacks. Finally, we will explain how we plan to improve the native scheduler to work with Topology Manager. Attendees will learn both current workarounds, and the future of topology aware scheduling in Kubernetes.</p> PUBLIC CONFIRMED Cloud Computing https:/fosdem.org/2021/schedule/event/cloud_kube_scheduler/ M.misc SWATI SEHGAL PUBLISH 10932@FOSDEM21@pentabarf.org 10932 ntsc ntsc Emulating the full NTSC stack Creating objective video artefacts en en_US Emulator Development 2021-02-06 14:00:00 +0100 2021-02-06 15:00:00 +0100 01:00:00:00 20210206T140000 20210206T150000 01:00:00:00 Emulating the full NTSC stack- Creating objective video artefacts <p>Many emulators offer a CRT filter, an artist's rendition of classic video.</p> <p>This presentation describes emulation of the an entire NTSC or PAL video device, to produce an engineer's rendition — starting from sync discrimination and separation, through PLLs into scan placement and via QAM to extracting colour.</p> PUBLIC CONFIRMED Emulator Development https:/fosdem.org/2021/schedule/event/ntsc/ D.emulator Thomas Harte PUBLISH 10958@FOSDEM21@pentabarf.org 10958 bach bach Bach Builds (on(ly)) Java Modules en en_US Friends of OpenJDK 2021-02-06 14:00:00 +0100 2021-02-06 14:40:00 +0100 00:40:00:00 20210206T140000 20210206T144000 00:40:00:00 Bach Builds (on(ly)) Java Modules <p>Java build tools were developed before Java modules were around -- Bach builds (on(ly)) Java modules!</p> PUBLIC CONFIRMED Friends of OpenJDK https:/fosdem.org/2021/schedule/event/bach/ D.openjdk Christian Stein PUBLISH 10963@FOSDEM21@pentabarf.org 10963 ttddocusaurus ttddocusaurus Taming the 'Saurus My experiments with the Docusaurus en en_US Tool The Docs 2021-02-07 14:00:00 +0100 2021-02-07 14:30:00 +0100 00:30:00:00 20210207T140000 20210207T143000 00:30:00:00 Taming the 'Saurus- My experiments with the Docusaurus <p>Originally having been developed for the open source projects at Facebook, Docusaurus now serves as an easy-to-use tool across many open-source projects.

To keep it simple, it's usually explained that Python will automatically pass the current instance as the first argument to the method: "self" will refer to the instance the method was called on. This high-level explanation really helps with keeping the focus on learning the basics of classes, but it also side-steps what is really going on: It makes it sound like process of inserting "self" is something <strong>automagical</strong> that the language just does for you. In reality, the mechanism behind inserting self isn't magical at all and it's something you can very much play with yourself.</p> <p>In this intermediate level talk, Sebastiaan Zeeff will take you down into the heart of the Python data model to explain how the mechanism behind inserting "self" works. He will talk about the <a href="https://docs.python.org/3/reference/datamodel.html#descriptors">descriptor protocol</a> and how it allows you to modify how attributes are accessed, assigned, or deleted in Python.

To get a grip on the different tools, understand what they can do and where their limitations are, the OC tooling workgroup decided to develop a capability model. This model outlines all required capabilities to cope with the open source challenge and allows to map the functionality of tools. Thus the model can be seen as a map through the djungle of tools. In this talk, Jan will introduce the model as well as briefly outline the most relevant capabilities.

Leaving fashions aside, some other technologies may actually be a better solution for some use cases and projects. Kubernetes is actually a very complex technology, with limited support for multi-tenancy and lacking secure isolation between tenants. Kubernetes does not offer cloud-like self-service provision features for users either. Cloud providers and cloud management tools try to bridge these gaps by offering managed Kubernetes-as-a-Service platforms, adding an extra control layer that ends up increasing management complexity, resource consumption and associated costs.</p> <p>OpenNebula brings exciting new features to the container orchestration ecosystem. OpenNebula’s recent integration with Docker Hub provides users with immediate access to official Docker images. Now they can be easily imported into an OpenNebula cloud and orchestrated as a KVM-based virtual machine, as a LXD system container or even as a Firecracker micro-VM. With its native support for multi-tenancy, self-service provision and secure isolation between tenants, OpenNebula has become a simpler alternative to Kubernetes to easily set up multi-tenant Containers-as-a-Service on private, hybrid and edge cloud environments.</p> <p>In this talk we will show a live demo on how to automatically deploy a Containers-as-a-Service on the edge to orchestrate multi-container applications using OpenNebula’s recent integration with the Docker Hub marketplace.</p> PUBLIC CONFIRMED Containers https:/fosdem.org/2021/schedule/event/containers_opennebula_k8s/ D.containers Marco Mancini PUBLISH 11308@FOSDEM21@pentabarf.org 11308 mariadb_json mariadb_json JSON Support: news, non-news, and the bigger picture en en_US MariaDB 2021-02-06 14:20:00 +0100 2021-02-06 14:45:00 +0100 00:25:00:00 20210206T142000 20210206T144500 00:25:00:00 JSON Support: news, non-news, and the bigger picture <p>This talk aims to cover everything about the current state of JSON support.</p> <p>First, I'll cover the newest addition, JSON_TABLE in MariaDB 10.6.</p> <p>Then, I'll discuss the power of JSONPath in MariaDB and how it compares to the SQL Standard and other databases.

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

This next generation virtualization technology was launched by AWS in late 2018 and is designed for secure multi-tenant container-based services. This integration provides an innovative solution to the classic dilemma between using containers—lighter but with weaker security—or Virtual Machines—with strong security but high overhead.</p> <p>Firecracker is an open source technology that makes use of KVM to launch lightweight Virtual Machines—called micro-VMs—for enhanced security, workload isolation, and resource efficiency. It is widely used by AWS as part of their Fargate and Lambda services. Firecracker opens up a whole new world of possibilities as the foundation for serverless offerings that need to deploy containerized critical applications nearly instantly while keeping them in isolation.</p> <p>OpenNebula is a simple, yet robust, open source platform for building Enterprise Clouds and managing Data Center virtualization. Its integration with public cloud providers offers additional flexibility in creating True Hybrid and Edge infrastructures. By incorporating Firecracker, OpenNebula now provides users with a powerful solution for serverless computing and an alternative, native model for secure container orchestration.</p> <p>In this talk we will explain the technical details of this integration and will show a live demo on how to easily deploy and orchestrate a composition of Docker Hub images running as Firecracker microVMs on a distributed bare-metal Edge infrastructure.</p> PUBLIC CONFIRMED Virtualization and IaaS https:/fosdem.org/2021/schedule/event/vai_serverless_opennebula/ D.virtualization Christian Gonzalez PUBLISH 11195@FOSDEM21@pentabarf.org 11195 firmware_baicipfosf firmware_baicipfosf Building an interactive Continuous Integration platform for Open Source Firmware en en_US Open Source Firmware, BMC and Bootloader 2021-02-06 14:30:00 +0100 2021-02-06 14:55:00 +0100 00:25:00:00 20210206T143000 20210206T145500 00:25:00:00 Building an interactive Continuous Integration platform for Open Source Firmware <p>During that presentation I will run a quick demo of the OSFCI infrastructure which is developed by HPE to validate and build Open Source Firmware stack on Proliant server.

An introduction to Object Storage for Kubernetes- Moving beyond file and block storage in Kubernetes <p>Kubernetes graduated Container Storage Interface (CSI) to GA status in v1.13. Since CSI’s origin, it has evolved to support a large number of vendors and storage formats. It has brought the industry together in consensus about the best practices in storage. However, CSI’s major limitation is that it only supports Block and File storage. The rapid growth of Object storage means that a growing share of the ecosystem is currently using ad-hoc solutions to leverage this new technology. Object storage is a fundamentally different paradigm where data is accessed over the network rather than locally. It allows applications to remain stateless while offloading state into a black box over the network. Object storage is the key enabler for cloud migration. This paradigm, however, does not have a standard mechanism for consumption in Kubernetes. COSI fundamentally exists to enable the natural consumption of object storage with Kubernetes.</p> PUBLIC CONFIRMED Software Defined Storage https:/fosdem.org/2021/schedule/event/sds_object_storage_for_k8s/ D.sds Jiffin Tony Thottan Krish Chowdhary PUBLISH 11392@FOSDEM21@pentabarf.org 11392 community_devroom_online_converences_newnormal community_devroom_online_converences_newnormal Online Conferences and the "new normal". en en_US Community devroom 2021-02-07 14:30:00 +0100 2021-02-07 14:50:00 +0100 00:20:00:00 20210207T143000 20210207T145000 00:20:00:00 Online Conferences and the "new normal". <p>In the MariaDB Foundation we have been trying to respond to the challenges of the "new normal" by organising a series of online events that we called MariaDB ServerFest.

And yet it works even without the root privilege.</p> <p>More info: https://norouter.io/docs/</p> PUBLIC CONFIRMED Software Defined Networking https:/fosdem.org/2021/schedule/event/sdn_norouter/ D.sdn Akihiro Suda PUBLISH 11072@FOSDEM21@pentabarf.org 11072 open_research_gaspard_monge open_research_gaspard_monge Free/Open source Research Software production at the Gaspard-Monge Computer Science laboratory Lessons learnt en en_US Open Research Tools and Technologies 2021-02-06 14:35:00 +0100 2021-02-06 15:00:00 +0100 00:25:00:00 20210206T143500 20210206T150000 00:25:00:00 Free/Open source Research Software production at the Gaspard-Monge Computer Science laboratory- Lessons learnt <p>In this talk we present the experience of the software produced, as part of the research activities, at the French Gaspard-Monge Computer Science laboratory (Laboratoire d'informatique Gaspard-Monge or LIGM in French).</p> PUBLIC CONFIRMED Open Research Tools and Technologies https:/fosdem.org/2021/schedule/event/open_research_gaspard_monge/ D.research Teresa Gomez-Diaz PUBLISH 11176@FOSDEM21@pentabarf.org 11176 nemolargescalemon nemolargescalemon Large-scale Network Monitoring: 3 Rules to Rule Them All en en_US Network monitoring, discovery and inventory 2021-02-06 14:35:00 +0100 2021-02-06 15:35:00 +0100 01:00:00:00 20210206T143500 20210206T153500 01:00:00:00 Large-scale Network Monitoring: 3 Rules to Rule Them All <p>So you want to monitor a large-scale network-- where do you start?

This is not only due to the unavailability of resources, but also to the absence of a structured formative process for the design and management of healthcare facilities. This situation strongly contributes to deepening inequalities in access to quality healthcare. Through an Open Society Foundations funded project, the Mboalab aims to remedy these inequalities by building Open-Source devices for medical labs. Local manufacturing can address the infrastructural barriers that prevent imported or donated equipment from being properly used, and can facilitate the diffusion of innovation into healthcare practice. This project is part of the large MboaLab mission to contribute to the Common good and catalyze sustainable local development through Open Science.</p> PUBLIC CONFIRMED Lightning Talks https:/fosdem.org/2021/schedule/event/prototyping_in_cameroon/ L.lightningtalks ELISEE JAFSIA PUBLISH 11183@FOSDEM21@pentabarf.org 11183 reverse_engineering reverse_engineering Reverse-Engineering of (binary) File-Formats From seemingly arbitrary zeros and ones to a PCB file. en en_US Open Source Computer Aided Modeling and Design 2021-02-07 14:40:00 +0100 2021-02-07 15:15:00 +0100 00:35:00:00 20210207T144000 20210207T151500 00:35:00:00 Reverse-Engineering of (binary) File-Formats- From seemingly arbitrary zeros and ones to a PCB file. <p>Ever found an interesting PCB design, but you are not able to open it with your favorite program?

At the same time, there have been almost little to no efforts in improving its computational efficiency since its first, to the presenter's best knowledge, introduction by Smith (1995) when the geospatial data resolution was relatively coarser. In this talk, the presenter introduces a new algorithm that applies Hack's law to the discovery of the longest flow path and its efficient implementation as a GRASS module called r.accumulate. He compares its performance to that of commercial ArcHydro's Longest Flow Path tool. Lastly, he introduces a proof-of-concept version of the Web-based Hydrologic Modeling System (WHydroMod) built using GRASS, PyWPS, MapServer, and OpenLayers, and discusses how r.accumulate can be used to improve the efficiency of geospatial computation for WHydroMod.</p> PUBLIC CONFIRMED Geospatial https:/fosdem.org/2021/schedule/event/raccumulate/ D.geospatial Huidae Cho PUBLISH 11628@FOSDEM21@pentabarf.org 11628 jakartaee9beyond jakartaee9beyond Jakarta EE 9 and Beyond en en_US Friends of OpenJDK 2021-02-06 14:40:00 +0100 2021-02-06 15:20:00 +0100 00:40:00:00 20210206T144000 20210206T152000 00:40:00:00 Jakarta EE 9 and Beyond <p>Jakarta EE 9 lowers the barriers of entry, ease migration, and lays a foundation for future innovation.</p> PUBLIC CONFIRMED Friends of OpenJDK https:/fosdem.org/2021/schedule/event/jakartaee9beyond/ D.openjdk Ivar Grimstad PUBLISH 11649@FOSDEM21@pentabarf.org 11649 jib jib Containerizing Spring Boot Applications with Jib en en_US Friends of OpenJDK 2021-02-07 14:40:00 +0100 2021-02-07 15:20:00 +0100 00:40:00:00 20210207T144000 20210207T152000 00:40:00:00 Containerizing Spring Boot Applications with Jib <p>Jib is a Java containerizer from Google that lets Java developers build containers using build tools like Maven and Gradle.</p> PUBLIC CONFIRMED Friends of OpenJDK https:/fosdem.org/2021/schedule/event/jib/ D.openjdk Ashish Choudhary PUBLISH 11117@FOSDEM21@pentabarf.org 11117 opensuse_microos opensuse_microos openSUSE MicroOS, a platform for everything from containers, to IoT, and even the desktop Bigger isn't better, slower isn't safer en en_US Distributions 2021-02-06 14:45:00 +0100 2021-02-06 15:30:00 +0100 00:45:00:00 20210206T144500 20210206T153000 00:45:00:00 openSUSE MicroOS, a platform for everything from containers, to IoT, and even the desktop- Bigger isn't better, slower isn't safer <p>An overview and discussion regarding the openSUSE Project's latest rolling-release distribution, MicroOS.

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

As applications become more complex and more distributed, they may span multiple Kubernetes clusters, or a combination of Kubernetes and on-premise workloads. While internal traffic within a Kubernetes cluster is handled by the CNI plugin, the external traffic between these workloads, or from workloads to end users, is often carried over a Software Defined Wide Area Network (SD-WAN), which is used for traffic optimization. The <a href="https://github.com/CloudNativeSDWAN"><strong>Cloud Native SD-WAN (CN-WAN) open source project</strong></a> was created to help SD-WAN deployments to identify Kubernetes applications and optimize traffic based on application requirements, thereby bridging together the <em>DevOps</em> from Kubernetes' cloud native world with the <em>NetOps</em> from the SD-WAN world.</p> <p>CN-WAN enables developers to <strong>annotate their applications</strong>, specifying the type of network traffic generated by the Kubernetes workload, and this information is then published into a service registry. The NetOps configuring the SD-WAN can take these annotations and develop network optimization policies with the clear knowlegde of the traffic type they intend to optimize.</p> <p>Join us for this presentation, where we will describe the components of the solution, the interfaces between the components, and how you can adapt this solution to different SD-WAN products and service registries.</p> PUBLIC CONFIRMED Software Defined Networking https:/fosdem.org/2021/schedule/event/sdn_k8s_cloud_native/ D.sdn Lori Jakab PUBLISH 11336@FOSDEM21@pentabarf.org 11336 open_compliance_reference_tooling open_compliance_reference_tooling Open Compliance Reference Tooling Leveraging Open Source Tools for Open Source Management en en_US OpenChain 2021-02-06 14:55:00 +0100 2021-02-06 15:40:00 +0100 00:45:00:00 20210206T145500 20210206T154000 00:45:00:00 Open Compliance Reference Tooling- Leveraging Open Source Tools for Open Source Management <p>Open Compliance Reference Tooling in action.

And their concerns are fully justified.</p> <p>So we at ONLYOFFICE, an open-source project with the focus on advanced and secure document processing, do our best to provide a comprehensive level of security for online doc editing and collaboration.</p> <p>With GDPR compliant ONLYOFFICE Docs, you get a wide range of security tools and services to protect yourself from unauthorized access, data leaks, or insider actions. Self-hosted ONLYOFFICE can be installed on your own private server, so all your data always stays ‘in-house.’ The server level of data protection is implemented, among other things, with JSON Web Token and configurable cache lifetime. Important is, that no user data is stored on the ONLYOFFICE server. Besides, there are additional security features such as restriction on copying, downloading and printing, watermarking, flexible document permissions, etc.</p> <p>The same applies to the integration of ONLYOFFICE Docs with other open-source services and platforms so that users of the combined solutions also get secure document editing and co-authoring.</p> <p>To make your experience even more secure, last year we implemented:</p> <ul> <li><p>Custom filter access permission that allows hiding the data you don’t want to show before sharing your spreadsheet. In other words, users won’t be able to change the filter you’ve applied before sharing your spreadsheet and will be able to work only with the specified fields.</p></li> <li><p>Storage encryption so that you can protect data at rest against breaches. If the storage encryption option is enabled, all the files stored in your ONLYOFFICE will be encrypted using the Advanced Encryption Standard, symmetric block cipher, also known as Rijndael, that encrypt data blocks of 128 bits using symmetric keys of 256 bits.</p></li> <li><p>The first version of ONLYOFFICE Private Rooms, protected workplaces where every symbol you type is encrypted using the unbreakable AES-256 algorithm, even if you are co-editing documents with your teammates in real-time. Files that are created, stored and shared within a Private Room never leave the directory and cannot be copied, re-distributed, or decrypted. Document encryption and decryption is performed strictly on the user’s machine end-to-end.</p></li> </ul> <p>Besides, we are now working on multi-functional secure forms for building any document template and secure form filling when your co-author is not permitted to see some parts of the doc.</p> PUBLIC CONFIRMED Collaborative Information and Content Management Applications https:/fosdem.org/2021/schedule/event/onlyofficeultimatesecurity/ D.collab Alex Mikheev PUBLISH 11517@FOSDEM21@pentabarf.org 11517 postgres_query_optimization postgres_query_optimization Adaptive Query Optimization in PostgreSQL: approaches and challenges en en_US PostgreSQL 2021-02-06 15:00:00 +0100 2021-02-06 15:30:00 +0100 00:30:00:00 20210206T150000 20210206T153000 00:30:00:00 Adaptive Query Optimization in PostgreSQL: approaches and challenges <p>Query optimizer is one of the key components which determines DBMS performance under OLAP workload. Nevertheless, it was shown that query optimizer often fails to find a good execution plan because of incorrect cardinality estimations. The perspective approach to improve cardinality estimation quality is adaptive query optimization. In contrast with classical approaches, which rely on the precomputed histograms, it utilizes the execution statistics of the previously executed queries to refine cardinality estimations.

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

At the University of Maryland I created an elective for undergraduates in the CS dept. that introduced DSP and SDR in a hands-on manner, and have since taught the course twice. During this course, students learn basic wireless communications and DSP concepts, and how to implement the techniques onto SDRs. Additional course learning objectives include digital signals, filtering, frequency domain, digital modulation, noisey channels, cellular, and IoT. The course utilizes open-source SDR toolkit software including GNU Radio and Python libraries, allowing students more interesting and engaging assignments/exercises and more advanced concepts to be explored. Every student had a PlutoSDR to use during the semester. What is unique about this course is that this material is typically taught at the graduate level within ECE, spread across numerous individual courses. CS students, at least at our university, do not get exposed to any DSP or signals background which is normally required to learn about SDR using traditional methods/textbooks, so they must start from scratch, which is why this course has heavy use of graphics, animations, and examples. As such, this course does not dive as deep into the mathematics behind the theory as a normal graduate level ECE course would. There is much more emphasis on "learning by doing", and actually creating SDR applications.</p> <p>In addition to the course I have created a free online textbook called PySDR, that is based on the material I taught in my course, which anyone can use to learn DSP and SDR using Python. My textbook does not use any custom libraries or code, it's essentially showing how to use straight Python (e.g. mostly numpy, scipy, and matplotlib) to actually do DSP and create SDR applications. Through feedback I've gotten from people using this online textbook, I have learned about what it takes to teach DSP and SDR to folks in a non-university setting. The source code used to generate the textbook (using Sphinx) is hosted on GitHub, so that readers can submit issues or even PRs, to date there has been several contributors. I'm hoping this presentation can show that you don't need to be a EE with a masters degree to dive into DSP and SDR.</p> PUBLIC CONFIRMED Free Software Radio https:/fosdem.org/2021/schedule/event/fsr_pysdr_guide_to_sdr_and_dsp_using_python/ D.radio Marc Lichtman PUBLISH 11167@FOSDEM21@pentabarf.org 11167 dynamicproxies dynamicproxies Dynamic Proxies in Java en en_US Friends of OpenJDK 2021-02-07 15:20:00 +0100 2021-02-07 16:00:00 +0100 00:40:00:00 20210207T152000 20210207T160000 00:40:00:00 Dynamic Proxies in Java <p>Java frameworks often need to dynamically create classes.</p> <p>One approach to do that easily in Java is dynamic proxies.</p> <p>In this talk, we will show how they compare to hand-written classes.</p> <p>We will then examine how we can use dynamic proxies to reduce the amount of code that we have to write.</p> PUBLIC CONFIRMED Friends of OpenJDK https:/fosdem.org/2021/schedule/event/dynamicproxies/ D.openjdk Heinz Kabutz PUBLISH 11247@FOSDEM21@pentabarf.org 11247 raku_digital_audio_das_server raku_digital_audio_das_server Programming Digital Audio Server (DAS) backend with Raku JUCE+Raku as the backend for Linux driven web audio services en en_US Perl and Raku Programming 2021-02-06 15:20:00 +0100 2021-02-06 16:20:00 +0100 01:00:00:00 20210206T152000 20210206T162000 01:00:00:00 Programming Digital Audio Server (DAS) backend with Raku- JUCE+Raku as the backend for Linux driven web audio services <p>Musicians, producers and composers use digital audio workstations (DAW) in daily work.

We present GossipSub, a gossip-based pubsub protocol, which, in contrast to past pubsub protocols, incorporates resilience against a wide spectrum of attacks.</p> <p>Firstly, GossipSub's mesh construction implements an eager push model keeps the fan-out of the pubsub delivery low and balances excessive bandwidth consumption and fast message propagation throughout the mesh. Secondly, through gossip dissemination, GossipSub realises a lazy-pull model to reach nodes far-away or outside the mesh. Thirdly, through constant observation, nodes maintain a score profile for the peers they are connected to, allowing them to choose the most well-behaved nodes to include in the mesh. Finally, and most importantly, a number of tailor-made mitigation strategies designed specifically for these three components make GossipSub resilient against the most challenging Sybil-based attacks. We test GossipSub in a testbed environment involving more than 5000 VM nodes deployed on AWS and show that it stays immune to all considered attacks. GossipSub is currently being integrated as the main messaging layer protocol in the Filecoin and the Ethereum 2.0 (ETH2.0) blockchains.</p> PUBLIC CONFIRMED Lightning Talks https:/fosdem.org/2021/schedule/event/gossipsub/ L.lightningtalks Yiannis Psaras PUBLISH 11433@FOSDEM21@pentabarf.org 11433 perl_the_hidden_gem perl_the_hidden_gem Perl, the hidden automation gem On how Perl can be used in almost every CI/CD environment, and you probably didn't know en en_US Lightning Talks 2021-02-07 15:20:00 +0100 2021-02-07 15:40:00 +0100 00:20:00:00 20210207T152000 20210207T154000 00:20:00:00 Perl, the hidden automation gem- On how Perl can be used in almost every CI/CD environment, and you probably didn't know <p>Modern deployment workflows extensively employ CI/CD tools for tasks that go from simple testing to automating the creation of container images.

Terraform is used for creating cloud instances which are used for development, building software, and testing. We also employ ReFrame for testing the different layers of the EESSI project, and the provided installations of scientific software applications. Finally, we use Singularity containers for having clean software build environments and for providing easy access to our software stack, for instance on machines without a native CernVM-FS client.</p> <p>In this talk, we will present how the EESSI project grew out of a need for more collaboration to tackle the challenges in the changing landscape of scientific software and HPC system architectures.

There are many profiling tools that can instrument serial and parallel codes, and gather performance data. However, analytics and visualization tools that are general, easy to use, and programmable are limited. Hatchet is an open-source Python library that can read profiling output of several tools, and enables the user to perform a variety of programmatic analyses on hierarchical performance profiles. Hatchet brings the power of modern data science tools such as pandas to bear on performance analysis. In this talk, we present a set of techniques and operations that build on the pandas data analysis library to enable analysis of performance profiles. These techniques, implemented in Hatchet, enable the filtering, aggregation, and pruning of structured data. In addition, Hatchet facilitates comparing performance profiles from multiple executions to understand the differences between them.</p> PUBLIC CONFIRMED HPC, Big Data and Data Science https:/fosdem.org/2021/schedule/event/hatchet/ D.hpc Abhinav Bhatele PUBLISH 11214@FOSDEM21@pentabarf.org 11214 public_database_as_a_service_for_open_source_distribution public_database_as_a_service_for_open_source_distribution Why Public Database as a Service is Prime for Open Source Distribution en en_US Distributions 2021-02-06 15:30:00 +0100 2021-02-06 15:55:00 +0100 00:25:00:00 20210206T153000 20210206T155500 00:25:00:00 Why Public Database as a Service is Prime for Open Source Distribution <p>The database market is changing drastically in ways no one imagined 5 years ago. Database vendors are moving away from traditional deployment methods and embracing database as a service (DBaaS) as the default method to offer their database technologies to consumers and users. Much of this movement has been built because of the success and popularity of DBaaS offerings by major cloud vendors. Unfortunately, this is leading to a new era of NROSS (Not really open source) technologies that pretend to be free, open, and transparent but simply are not. As people wake up from the hangover’s caused by the incompatibilities, lack of portability, and increased costs they are looking at how to reclaim the openness, transparency, and freedom true OpenSource has provided them in the past. We will explore the trends and give his opinions and ideas on how we need to disrupt the current trends to keep open source open, and give users the freedom of having a quality alternative.</p> PUBLIC CONFIRMED Distributions https:/fosdem.org/2021/schedule/event/public_database_as_a_service_for_open_source_distribution/ D.distributions Peter Zaitsev PUBLISH 11273@FOSDEM21@pentabarf.org 11273 lo_lowithmariadb lo_lowithmariadb Using LibreOffice with MariaDB [and Docker] en en_US LibreOffice 2021-02-07 15:30:00 +0100 2021-02-07 16:00:00 +0100 00:30:00:00 20210207T153000 20210207T160000 00:30:00:00 Using LibreOffice with MariaDB [and Docker] <p>This talk will show how to use LibreOffice's graphical user interface (GUI) to interact with your favorite database.

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

In many cases, it is the most suitable option for geometric data like points, boxes, etc. An easy way to increase the selection speed is to eliminate the need for the results recheck by a table. But with the index being single-column by design we could not enjoy index-only scans for multicolumn queries.</p> <p>The talk covers my improvement of the SPGiST access method. Non-key columns can now be included in a single key-column index in a way, similar to that have in GiST and B-tree. This adds the ability to make fast index-only scans for multicolumn queries. Also, non-key columns with data types without SPGiST opclass can be added, which creates an opportunity for the new use cases. In my presentation, I will justify the modification, discuss new use cases of GiST and SPGiST indexes, and share some performance benchmarks.</p> PUBLIC CONFIRMED PostgreSQL https:/fosdem.org/2021/schedule/event/postgresql_speed_improvements_and_new_use_scenarios_for_spgist_access_method/ D.postgresql Pavel Borisov PUBLISH 11519@FOSDEM21@pentabarf.org 11519 python_kedro python_kedro From Jupyter Notebook to production code a Kedro introduction en en_US Python 2021-02-07 15:30:00 +0100 2021-02-07 16:00:00 +0100 00:30:00:00 20210207T153000 20210207T160000 00:30:00:00 From Jupyter Notebook to production code- a Kedro introduction <p>Have you ever had issues to share your Jupyter Notebooks?

With their standardization at the IETF almost complete and several mature implementations being deployed, we can start looking into which performance improvements they bring in practice. There's just one problem though: they're quite complex and difficult to test. Using high level tooling like lighthouse might show that they're faster or slower, but rarely why.</p> <p>But problems are there to be solved, and that's what I've been doing for the past 2 years with the qlog and qvis projects. The qlog structured endpoint logging format (https://github.com/quiclog/internet-drafts) is supported by over 70% of all QUIC implementations and allows you to extract low-level protocol information in JSON directly from the client and server. These traces can then be loaded for analysis in different interactive visualizations in our open-source qvis toolsuite (https://qvis.edm.uhasselt.be). This brings an unparalleled opportunity to analyze performance problems and opportunities to the new protocols, as these tools start where the browser devtools end.</p> <p>In this talk, we will explore QUIC and HTTP/3's main performance oriented features, such as 0-RTT connection establishment, advanced congestion and flow control, stream multiplexing and prioritization, and Head-of-Line blocking removal in-depth.

As such, DSSoCs can boost the performance and energy-efficiency of software-defined radio (SDR) applications without degrading their flexibility. Harvesting the full potential of DSSoCs depends critically on integrating an optimal combination of computing resources and their effective runtime utilization. For this reason, the design space exploration process requires evaluation frameworks to guide the design process. Full-system simulators, such as gem5, can perform instruction-level cycle-accurate simulation. However, this level of detail leads to long execution times and is beyond high-level design space exploration requirements. In contrast, hardware emulation using Field-Programmable Gate Array (FPGA) prototypes are substantially faster. However, they involve significantly higher development effort to implement the target SoC and applications. Given the design complexity, there is a strong need for a simulation environment that enables rapid, high-level, simultaneous exploration of scheduling algorithms and power-thermal management techniques. To this end, we present DS3, an open-source system-level domain-specific system-on-chip simulation framework that targets SDR applications. DS3 framework enables (1) run-time scheduling algorithm development, (2) dynamic thermal-power management (DTPM) policy design, and (3) rapid design space exploration. DS3 facilitates plug-and-play simulation of scheduling algorithms; it also incorporates built-in heuristics and a constraint programming-based scheduler to provide an upper bound of performance (i.e., optimal schedule for a set of applications and an SoC configuration) for users. Hence, it can be used to develop and evaluate new schedulers that can be integrated into GNU Radio. DS3 also includes power dissipation and thermal models that enable users to design and evaluate new DTPM policies. Furthermore, it features built-in dynamic voltage and frequency scaling (DVFS) governors deployed on commercial SoCs. In this talk as we discuss the DS3 capabilities, we will present a benchmark application suite with applications from wireless communications and radar processing domains including WiFi TX/RX, low-power single-carrier TX/RX, range detection, and pulse Doppler. We will conclude the talk with design-space exploration studies using these applications.</p> PUBLIC CONFIRMED Free Software Radio https:/fosdem.org/2021/schedule/event/fsr_optimization_of_sdr_apps_on_heterogeneous_socs/ D.radio Samet E Arda PUBLISH 11125@FOSDEM21@pentabarf.org 11125 reuse reuse REUSE Best practices for declaring copyright and licenses en en_US OpenChain 2021-02-06 15:45:00 +0100 2021-02-06 16:30:00 +0100 00:45:00:00 20210206T154500 20210206T163000 00:45:00:00 REUSE- Best practices for declaring copyright and licenses <p>Why is it so hard to detect the licensing and copyright information of source code?

The Asynchronous Replication Connection Failover feature complements this by further increasing the resilience of replication connections between a replica and a set of sources. It allows asynchronous replicas to switch to a new replication source when the current connection fails. Therefore, an asynchronous replica can automatically switch-over its replication connection to a new member, when it is replicating from a Group Replication group, for instance.</p> <p>In this session we will present how Asynchronous Replication Connection Failover feature automates the process of re-establishing a replication connection to another source, upon failure of the current one. We will also present about how this feature integrates with Group Replication and thus how setting it up can be automated as well.</p> <p>Come and learn more about this new and exciting replication feature in MySQL, directly from the engineers developing the product.</p> PUBLIC CONFIRMED MySQL https:/fosdem.org/2021/schedule/event/automatic_mysql_failover/ D.mysql hemant dangi PUBLISH 11437@FOSDEM21@pentabarf.org 11437 the_open_source_designers_toolbox the_open_source_designers_toolbox The Open Source Designer's ToolBox Recommended Techniques and Tools for Open Source Designers en en_US Open Source Design 2021-02-07 16:00:00 +0100 2021-02-07 16:20:00 +0100 00:20:00:00 20210207T160000 20210207T162000 00:20:00:00 The Open Source Designer's ToolBox- Recommended Techniques and Tools for Open Source Designers <p>As designers get introduced to FOSS, what should they know?

Traditionally add-in-cards have relied on IPMI based manageability solutions. However, the newer standards from DMTF (PMCI protocol stack) provide more robust and scalable solutions for add-in card manageability. SPDM provides the attestation and secure communication channel between the BMC and the add-in cards. MCTP/PLDM stack provides mechanisms for the BMC to auto discover card’s capabilities and carry out manageability functions like sensor monitoring, event logging, firmware updates etc. This provides significant advantage over IPMI which lacked secure communications and had limitations on supporting advanced high speed interfaces like PCIe and had limitations on number of sensors it could support.</p> <p>We plan to present on how add-in-cards can be managed through PMCI protocols and how do we model the add-in-cards’ manageability functions in a way a DataCentre orchestration software can consume it (i.e. Redfish modelling of add-in-cards). The implementation is planned for OpenBMC and a variety of Add-In-Cards can be supported through a standard manageability model.</p> PUBLIC CONFIRMED Open Source Firmware, BMC and Bootloader https:/fosdem.org/2021/schedule/event/firmware_ospsifam/ D.firmware Sumanth Bhat Cezary Sobczak PUBLISH 11550@FOSDEM21@pentabarf.org 11550 concurrencydebugging concurrencydebugging JCStress: Eliminating the Nightmare of Debugging Concurrency Problems en en_US Friends of OpenJDK 2021-02-07 16:00:00 +0100 2021-02-07 16:40:00 +0100 00:40:00:00 20210207T160000 20210207T164000 00:40:00:00 JCStress: Eliminating the Nightmare of Debugging Concurrency Problems <p>Are you sure your concurrency code will not fail?</p> <p>Writing concurrent programs is hard.

Think big data, storage, analytics, 5G, virtual network functions, then encrypt it all at 40Gbps line rates. Kubernetes and the Kubernetes network model are increasingly seen as essential to help manage these workloads at scale. But the cost of containerization and container networking can be hard to swallow for workloads that are often used to having dedicated NICs and physical hardware. Our novel solution was to cook up a feast that is a fusion of two worlds: combining Calico, the popular cloud native Kubernetes network plugin, with VPP, a very fast and scalable userspace packet processing software.

Originally conceived for graphic designers to provide a series of tasks not available with other tools, it evolved into a platform widely used in research and data journalism contexts that provides simple ways to map data dimensions onto visual variables. It presents a chart-based approach to data visualisation: each visual model is an independent module exposing different visual variables that can be used to map data dimensions. Consequently, users can create complex data visualisations. Finally, the tool is meant to produce outputs that are open, that is, not subjected to proprietary solutions, which can be further edited. Thanks to an intuitive user interface and experience drafting visualizations become an easy task, enabling the user to produce the visualizations not only as a mere output but also as a tool within the research process. Last year we launched a successful crowdfunding campaign to raise funds for the redesign and development of a new version of RAWGraphs, that will be released in the first months of 2021. The new version is written from scratch with the aim to make the tool more flexible for customisation and to create an active community also on the development side. The talk aims at presenting how RAWGraphs has been used in research context and our strategies to keep the project free, open source, economically sustainable and independent.</p> PUBLIC CONFIRMED Open Research Tools and Technologies https:/fosdem.org/2021/schedule/event/open_research_rawgraphs/ D.research Giorgio Uboldi PUBLISH 11405@FOSDEM21@pentabarf.org 11405 tee_trusted_rv tee_trusted_rv Trusted RV: 64bit RISC-V TEE with Secure CoProcessor as Root of Trust en en_US Hardware-Aided Trusted Computing 2021-02-06 16:15:00 +0100 2021-02-06 16:40:00 +0100 00:25:00:00 20210206T161500 20210206T164000 00:25:00:00 Trusted RV: 64bit RISC-V TEE with Secure CoProcessor as Root of Trust <p>Trusted RV is a combination of 4 core 64bit RISC-V (AC: Application Core) and 1 core 32bit RISC-V Secure Coprocessor (SU: Secure Unit).

This is due to the fact that a variety of celestial objects emit electromagnetic radiation at radio wavelengths, which has led to the development of radio telescopes capable of revealing the otherwise-hidden astrophysical properties of the universe. An important requirement that makes radio astronomy observations and analysis possible is an appropriate software pipeline compatible with the spectrometers with which radio observatories are equipped. In this work, we present Virgo: a versatile software solution for radio telescopes.</p> <p>Virgo is an easy-to-use open-source spectrometer and radiometer based on Python and GNU Radio (GR) that is conveniently applicable to any radio telescope working with a GR-supported software-defined radio (SDR). In addition to data acquisition, Virgo also carries out automated analysis of the recorded samples, producing an averaged spectrum, a calibrated spectrum, a dynamic spectrum (waterfall), a time series (power vs time) and a total power distribution plot.</p> <p>By additionally providing the observer with an important set of utilities, Virgo also makes for a great tool for planning (radio) observations. This includes the ability to compute the position of astronomical sources in the sky for a given date, estimate the right ascension and declination given the observer's coordinates along with the altitude and azimuth the telescope is pointing to and convert equatorial to galactic coordinates with the help of the open-source Astropy package.</p> PUBLIC CONFIRMED Lightning Talks https:/fosdem.org/2021/schedule/event/virgo/ L.lightningtalks Apostolos Spanakis-Misirlis PUBLISH 10906@FOSDEM21@pentabarf.org 10906 ttdlinkcheck ttdlinkcheck Check your links with the Link Check suite Benefits of using Markdown Link Check and related tools en en_US Tool The Docs 2021-02-07 16:30:00 +0100 2021-02-07 17:00:00 +0100 00:30:00:00 20210207T163000 20210207T170000 00:30:00:00 Check your links with the Link Check suite- Benefits of using Markdown Link Check and related tools <p><a href="https://github.com/tcort/markdown-link-check">Thomas Cort link checking suite</a> is Node.js software to make the checking of links in documentation sites (and not only doc) easy and efficient.

We ported containerd to macOS first (*1), which is currently under review, and run Linux applications with Linux Kernel Library (LKL), a library version of Linux kernel, which have no compatibility concerns as LKL is derived from Linux kernel.

On the other hand, they give rise to a number of challenges on a) designing and implementing a suitable architecture for the needs of the target applications, b) deploying dynamic and low-overhead resource management strategies, and c) effectively enabling execution of pipelined workflows for streaming applications. Furthermore, application developers need productive tools to port their software-defined radio applications to increasingly heterogeneous SoCs. We think that application developers should not waste their time reading datasheets or APIs for SoC-specific kernel extensions just to take full advantage of their hardware. With these in mind, this talk will discuss strategies we are using to address the aforementioned inter-related challenges through our vertically integrated compile-time and run-time environment CEDR: a Compiler-integrated, Extensible, DSSoC Runtime.</p> <p>CEDR is an open-source ecosystem that runs in Linux user-space and enables compilation and development of user applications, resource management strategies, and accelerator integration in one unified framework. CEDR supports highly recurring, stream-based application graphs through pipelined execution and processing element based work queues. CEDR is built on a thread-per-PE scheduling methodology, enables integration of complex resource management heuristics that rely on work queues and require reservation-based policies. CEDR supports contemporary scheduling algorithms built on imitation learning (IL) that uses complex schedulers offline to construct an Oracle and effortlessly replicates those decisions online using machine learning models such as regression trees and neural networks. We will demonstrate CEDR deployed on the Zynq UltraScale MPSoC by conducting execution time, throughput, resource utilization analysis through dynamically arriving workload scenarios composed of Radar and WiFi applications. We will demonstrate the distinct plug-and-play integration points offered by CEDR for application engineers and hardware architects through case studies that illustrate our ability to rapidly evaluate various configurations of applications, schedulers, and accelerator IPs.</p> PUBLIC CONFIRMED Free Software Radio https:/fosdem.org/2021/schedule/event/fsr_runtime_strategies_and_scheduling_of_sdr_on_heterogeneous_hw/ D.radio Joshua Mack PUBLISH 11538@FOSDEM21@pentabarf.org 11538 declarative_ready_unidirectionaldataflow_with_coroutines declarative_ready_unidirectionaldataflow_with_coroutines Getting ready for Declarative UIs with Unidirectional Data Flow using Kotlin Coroutines Unidirectional Data Flow in action: suspend functions, Flow & StateFlow to make our Reactive apps prepared for Declarative UIs. en en_US Kotlin 2021-02-07 16:40:00 +0100 2021-02-07 17:25:00 +0100 00:45:00:00 20210207T164000 20210207T172500 00:45:00:00 Getting ready for Declarative UIs with Unidirectional Data Flow using Kotlin Coroutines- Unidirectional Data Flow in action: suspend functions, Flow & StateFlow to make our Reactive apps prepared for Declarative UIs. <p>Unidirectional Data Flow (UDF) is a powerful technique that enhances our Reactive apps to work deterministically. Synchronising our views with fresh data was never an easy task to accomplish. For this same reason, there are mechanisms that support us to make that possible. Surely callbacks were a thing in the past, however, they were an antipattern themselves due to the lack of readability. Now we don't need to deal with them any more thanks to Kotlin Coroutines. Getting ready for Declarative UIs with Kotlin Coroutines and friends is indeed feasible, now we could use suspend functions, Flow and in the end StateFlow would make our Reactive apps ready for Declarative UIs.

Bitswap is being used in the InterPlanetary File System architecture as the main content exchange protocol, as well as in the Filecoin network as part of the block synchronisation protocol. In this work, we present Bitswap’s baseline design and then apply several new extensions with the goal of improving Bitswap’s efficiency and efficacy and minimizing its bandwidth fingerprint. Most importantly, our extensions result in a substantial increase to the protocol’s content discovery rate. This is achieved by using the wealth of information that the protocol acquires from the content routing subsystem to make smarter decisions on where to fetch the content from.</p> <p>This talk is focused on sharing the operation of Bitswap, the testbed we build to test improvements of Bitswap, and the ways in which we improved Bitswap building the foundation for research lines on file-sharing in P2P networks.</p> PUBLIC CONFIRMED Beyond Blockchain - Distributed Web https:/fosdem.org/2021/schedule/event/ipfs/ D.blockchain Alfonso de la Rocha PUBLISH 10980@FOSDEM21@pentabarf.org 10980 nyxtbrowser nyxtbrowser Nyxt browser configurable computing en en_US Declarative and Minimalistic Computing 2021-02-07 16:45:00 +0100 2021-02-07 17:10:00 +0100 00:25:00:00 20210207T164500 20210207T171000 00:25:00:00 Nyxt browser- configurable computing <p>Nyxt is the configurable web browser.

The individual object positions can be specified manually in terms of constraints that are solved using a numerical solver. Once an assembly is defined and all the positions specified it can be exported to STEP preserving the assembly structure or an internal OpenCascade XML format.

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

From the humble generic GNU Make to large scale platforms like Apache Airflow you would think that there is something there to satisfy everyone. All of these systems have one thing in common: they have a strong focus on partitioning large computations and scheduling work units, but when it comes to managing the software environments that are the context of each of the planned computations, they are often remarkably shy to offer opinionated solutions.</p> <p>Software management and deployment often seems like an afterthought. Workflow language designers increasingly seem to be following the devops trend of resorting to opaque application bundles to satisfy application and library needs. While this strategy has some advantages it also comes with downsides that rarely seem to be weighed carefully.</p> <p>We present the Guix Workflow Language --- not as a solution to the question of software deployment in HPC workflows, but as an instance of convergent evolution: growing a workflow language out of a generic reproducible software management and deployment system (GNU Guix) instead of sprucing up a workflow language with software deployment features. We hope to encourage a discussion about the current state of workflow languages in HPC: when it comes to software and distributed computations, are we approaching the peak or do we circle a local maximum?</p> PUBLIC CONFIRMED HPC, Big Data and Data Science https:/fosdem.org/2021/schedule/event/guix_workflow/ D.hpc Ricardo Wurmus PUBLISH 11037@FOSDEM21@pentabarf.org 11037 flux flux Flux: Solving Exascale Workflow and Resource Challenges Plus - How Open-Source Drives Our Project Design en en_US HPC, Big Data and Data Science 2021-02-07 17:00:00 +0100 2021-02-07 17:30:00 +0100 00:30:00:00 20210207T170000 20210207T173000 00:30:00:00 Flux: Solving Exascale Workflow and Resource Challenges- Plus - How Open-Source Drives Our Project Design <p>Many emerging scientific workflows that target high-end HPC systems require a complex interplay with resource and job management software (RJMS). However, portable, efficient and easy-to-use scheduling of these workflows is still an unsolved problem. In this talk, we present Flux, a next-generation RJMS designed specifically to address the key scheduling challenges of modern workflows in a scalable, easy-to-use, and portable manner. At the heart of Flux lies its ability to be seamlessly nested within batch allocations created by itself as well as other system schedulers (e.g., SLURM, MOAB, LSF, etc), serving the target workflows as their “personal RJMS instances”. In particular, Flux’s consistent and rich set of well-defined APIs portably and efficiently support those workflows that can feature non-traditional patterns such as complex co-scheduling, massive ensembles of small jobs and coordination among jobs in an ensemble.</p> <p>We will also cover how the Flux-Framework project is structured around open-source development, including our use of the Collective Code Construction Contract (C4), RFCs, LGPL, and various online open-source platforms. We discuss how these choices of open-source processes have influenced the repo structure, the code, our collaborations, and even the sub-teams within the project.</p> PUBLIC CONFIRMED HPC, Big Data and Data Science https:/fosdem.org/2021/schedule/event/flux/ D.hpc Stephen Herbein PUBLISH 11094@FOSDEM21@pentabarf.org 11094 firmware_uoifaaffsdc firmware_uoifaaffsdc Using OpenSPDM in Firmware as a Foundation for Secure Device Communication en en_US Open Source Firmware, BMC and Bootloader 2021-02-07 17:00:00 +0100 2021-02-07 17:45:00 +0100 00:45:00:00 20210207T170000 20210207T174500 00:45:00:00 Using OpenSPDM in Firmware as a Foundation for Secure Device Communication <p>Security Protocol and Data Model (SPDM) is a standard published by the Distributed Management Task Force (DMTF) organization Platform Management Components Intercommunication (PMCI) working group.

This simplification of cloud programming appears ideal (in theory) but the catch is that when someone needs to perform a more complex task, things could get a bit more complicated.</p> <p>Hardware acceleration, for instance, has been a pain point, even for traditional cloud computing programming models: IaaS providers chose dedicated solutions to avoid interference and preserve tenant isolation (device passthrough), while losing one of the most important benefits of virtualization, flexibility in workload placement through live migration. Various solutions have been proposed to overcome this limitation (API remoting, hardware slicing etc.). In the Serverless world though, do we need users to interface with a hardware device directly?</p> <p>Most serverless deployments are backed by containers, however, the most popular (and used) one, AWS Lambda, uses a ligthweight VMM (AWS Firecracker) integrated in the container ecosystem, in order to ensure strict isolation, while maintaining scalability. To this end, enabling hardware acceleration on this kind of deployment incurs the same pain points with traditional cloud infrastructure.</p> <p>Kata containers evolved from clear containers and offer hypervisor support for popular orchestrators container deployments such as docker, Kubernetes etc. Through kata containers, AWS Firecracker VMs can be easily provisioned as Pods on a kubernetes system, serving workloads prepared as container images. We build on the kata container runtime and port the necessary components to support vAccel, a lightweight framework for hardware acceleration on VMs, on Firecracker.</p> <p>In this talk, we briefly go through vAccel, its design principles and implementation, while focusing on the integration with kata-containers and the end-to-end system applicability on ML inference workloads. We present a short patch for kata-containers to support AWS Firecracker v0.23.1, and go through the necessary patching to add the vAccel framework on k8s.

Unfortunately, the GNU Radio SDR framework does not directly support such devices. Many workarounds have been developed to allow accelerator devices to be used within GNU Radio, but each comes with performance and/or flexibility tradeoffs. To solve these problems work is currently underway to develop generic support for accelerator devices within GNU Radio itself. The focus of this work is to modify GNU Radio to allow support for custom buffers. Custom buffer support will allow GNU Radio to directly utilize device specific buffers (e.g. DMA buffers) and therefore eliminate the need to double copy in order to move data into and out of an accelerator device. Furthermore, the custom buffer concept can be extended to allow “zero copy” data access between two kernels on the same accelerator device. This presentation will cover the design and current status of custom buffer support for GNU Radio.</p> PUBLIC CONFIRMED Free Software Radio https:/fosdem.org/2021/schedule/event/fsr_improving_gnu_radio_accelerator_device_dataflow/ D.radio David Sorber PUBLISH 11299@FOSDEM21@pentabarf.org 11299 minimalistdb minimalistdb Ordered Key-Value Stores A minimalist's database en en_US Declarative and Minimalistic Computing 2021-02-07 17:10:00 +0100 2021-02-07 17:30:00 +0100 00:20:00:00 20210207T171000 20210207T173000 00:20:00:00 Ordered Key-Value Stores- A minimalist's database <p>One of the great strength of Scheme is how flexible it is to the extent where you feel at home whatever the Scheme, the system will adapt itself to your needs, making it possible to re-use your knowledge.

While they have some downsides for measuring the performance, e.g. since they test corner cases or use functional utilities like mocks, they still are a way of measuring realistic use cases with nearly no manual effort.</p> <p>Therefore, we develop the tool Peass (https://github.com/DaGeRe/peass), which transforms unit tests into performance unit tests and measures their performance. The stand-alone tool Peass can be integrated into the CI-process using Peass-CI, which makes it possible to run performance tests with every build in Jenkins.</p> PUBLIC CONFIRMED Continuous Integration and Continuous Deployment https:/fosdem.org/2021/schedule/event/identifying_performance_changes_using_peass/ D.cicd David Georg Reichelt PUBLISH 11709@FOSDEM21@pentabarf.org 11709 realtime_3d_graphics_with_kotlin realtime_3d_graphics_with_kotlin Realtime 3D graphics and VR with Kotlin and Vulkan Let's enjoy the scenery en en_US Kotlin 2021-02-07 17:25:00 +0100 2021-02-07 18:00:00 +0100 00:35:00:00 20210207T172500 20210207T180000 00:35:00:00 Realtime 3D graphics and VR with Kotlin and Vulkan- Let's enjoy the scenery <p>This talk is gonna be about the scenery framework, a framework we have developed for visualising geometry and large volumetric data (TB+) using Kotlin and Vulkan or OpenGL.

Knowing that a good document requires both good content and presentation, I proposed and led the creation of a simple workflow amenable to our team's software engineers and data scientists: treating the white paper text as code with technologies including Markdown, GitHub Enterprise, Pandoc, LaTeX, and a review process that gets the tooling out of the way in order to enable content authors to focus less on logistics and more on writing and reviewing. The result was that a team of seven engineers and data scientists created a 50-page document containing text, diagrams, equations, graphics, and more in just two weeks. The result greatly pleased our directors and executives. They praised our team not only for the incredibly valuable content but also for the professional appearance of the document. When they learned about the peer review process we used to create it, they wanted more teams to use it.</p> <p>This talk focuses on the problems of passing around files by email or shared drives, the problems of collaborative editing of online documentation, and the problems we're still addressing in our solution that we've now used to author several significant internal documents.</p> PUBLIC CONFIRMED Tool The Docs https:/fosdem.org/2021/schedule/event/ttddatascience/ D.docs Colin Dean PUBLISH 10890@FOSDEM21@pentabarf.org 10890 python_escaping_cargo_cult python_escaping_cargo_cult Escaping the Cargo Cult How to structure your project without losing your mind. en en_US Python 2021-02-07 17:30:00 +0100 2021-02-07 18:00:00 +0100 00:30:00:00 20210207T173000 20210207T180000 00:30:00:00 Escaping the Cargo Cult- How to structure your project without losing your mind. <p>Structuring a Python project is often non-trivial.

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

What used to be the home turf of for-profit publishers has become a buzzing field of technological innovation. Scholarly metrics, not only limited to citations and altmetrics, come from a host of data providers using an even wider range of technologies to capture and disseminate their data. Citations come as closed or open data, using traditional text processing or AI methods by private corporations, research projects or NGOs. What is missing is a language and standard to talk about the provenance of scholarly metrics.</p> <p>In this lightning talk, I will present an argument why we need to pay more attention to the processes of tracing and patterning that go into the creation of the precious data that determine our academic profiles, influence hiring and promotion decitions, and even national funding strategies. Furthmermore, I present an early prototype of Metrics in Context, a data specification for scholarly metrics implemented in Frictionless Data. Additionally, the benefits and application of Metrics in Context is presented using both traditional citation data and a selection of common altmetrics such as the number of Tweets or FB shares.</p> <hr /> <p>[1] "Unceded lands are territories that were never signed away by the Indigenous people who inhabited them before Europeans settled in North America.

For example, a Suricata alert might require the context of Zeek's connection logs for the alert to become actionable. Normally the best way to make such correlations is by manually identifying the flow tuple involved, in each of the monitor outputs involved, around the timestamps in question -- a tedious and error-prone task.</p> <p>To simplify this process we're standardizing a straightforward algorithm, dubbed "Community ID" (https://github.com/corelight/community-id-spec), that produces short textual hashes that reliably identify network flows directly at the source. Flow correlation then becomes a straightforward string comparison operation. Popular open-source network monitoring solutions now include support for this emerging standard, including Suricata, Wireshark, and Zeek, and there's a growing library of reusable implementations in various common programming languages.</p> <p>In this talk we will motivate the Community ID standard, report on its current implementation status, and demonstrate it to the community.</p> PUBLIC CONFIRMED Software Defined Networking https:/fosdem.org/2021/schedule/event/sdn_community_id/ D.sdn Christian Kreibich PUBLISH 11280@FOSDEM21@pentabarf.org 11280 open_research_reverse_engineering open_research_reverse_engineering Reverse-engineering as a crossroads for investigation, science and open tools and technologies We are experimentally trying to revisit the practice of reverse-engineering to explore these possible and effective contributions in the case of investigation (journalism, activism, science, art). en en_US Open Research Tools and Technologies 2021-02-06 17:40:00 +0100 2021-02-06 17:50:00 +0100 00:10:00:00 20210206T174000 20210206T175000 00:10:00:00 Reverse-engineering as a crossroads for investigation, science and open tools and technologies- We are experimentally trying to revisit the practice of reverse-engineering to explore these possible and effective contributions in the case of investigation (journalism, activism, science, art). <p>“We want (Exposing the Invisible) to inspire a new generation of people committed to transparency and accountability.” (Tactical Tech).
