Recent security best-practices recommend, and certain highly security-conscious organizations are beginning to require, that SECCOMP be used to the extent possible. The major web browsers, container runtime engines, and systemd are all examples of software that already support SECCOMP.</p> <p>This talk covers SECCOMP applied to PostgreSQL via 2 different methods -- namely top-down using systemd, and at the session level using a PostgreSQL extension called pgseccomp. The two methods will be explained and compared. We will also discuss how and why the two methods might be used in conjunction. Finally, a process to determine the list of expected/legitimate PostgreSQL kernel syscalls is described.</p> PUBLIC CONFIRMED Databases https:/fosdem.org/2020/schedule/event/seccomp/ K.1.105 (La Fontaine) Joe Conway PUBLISH 9246@FOSDEM20@pentabarf.org 9246 continuous_delivery_starts_with_continuous_infrastructure continuous_delivery_starts_with_continuous_infrastructure Continuous Delivery starts with Continuous Infrastructure en en_US Continuous Integration and Continuous Deployment 2020-02-02 09:00:00 +0100 2020-02-02 09:40:00 +0100 00:40:00:00 20200202T090000 20200202T094000 00:40:00:00 Continuous Delivery starts with Continuous Infrastructure <p>Most organisations start their journey towards Continuous Delivery with their development teams, or often their web or mobile teams. I’ve seen many of these journeys fail because “ops” was not included in the picture. The organisation assumed DevOps didn’t need ops. So the team didn’t adapt, didn’t provide the right stacks, couldn’t support the tools. I’ve started a number of successful journeys with the ops teams doing Continuous Delivery of their infrastructure as code. They changed their mindset, allowing them to understand, support and onboard the development teams.

Ceph Object Storage Gateway (RGW) provides a RESTful object storage interface to the Ceph Storage cluster. It provides an interface that is compatible with a large subset of AWS S3 APIs.</p> <p>In this talk we discuss the implementation of a subset of the APIs of AWS Secure Token Service (STS). AWS STS is a web service which enables identity federation and cross-account access by providing temporary security credentials.</p> <p>Ceph Object Storage Gateway now supports some APIs of AWS STS particularly related to web identity federation and cross-account access. The advantages of these temporary credentials are that they automatically expire after a certain duration, provide limited access (via IAM policies) to resources, are provided to the user upon request, and obviate the need for users/ applications to save permanent security credentials thereby removing a potential security loophole.</p> <p>As an example consider a web application that has users and needs access to RGW S3 buckets to read/ write large files. The application can delegate identity management to a trusted third party identity provider(IDP). It can get temporary credentials from STS after authenticating with the IDP and access the required RGW S3 buckets.</p> PUBLIC CONFIRMED Software Defined Storage https:/fosdem.org/2020/schedule/event/sds_ceph_sts_in_object_storage/ H.1308 (Rolin) Pritha Srivastava PUBLISH 9394@FOSDEM20@pentabarf.org 9394 osi osi Open Source Under Attack How we, the OSI and others can defend it en en_US Freedom 2020-02-02 09:00:00 +0100 2020-02-02 09:50:00 +0100 00:50:00:00 20200202T090000 20200202T095000 00:50:00:00 Open Source Under Attack- How we, the OSI and others can defend it <p>Whether it is "Open Core", the Mongo SSPL or the Common Clause, the core ethos of open source has been under attack for some time.

They’re becoming increasingly popular, for DevOps and other teams, due to recruitment, diversity, flexibility and cost savings. Challenges arise due to timezones, language barriers, cultures and ways of working. People actively participating in Open Source communities tend to be effective in distributed teams. This session looks at how to apply core Open Source principles to distributed teams in Enterprise organisations, and the importance of shared purposes/goals, (mis)communication, leading vs managing teams, sharing and learning. We'll also look at practical aspects of what's worked well for others, such as alternatives to daily standups, promoting video conferencing, time management and virtual coffee breaks. This session is relevant for those leading or working in distributed teams, wanting to know how to cultivate an inclusive culture of increased trust and collaboration that leads to increased productivity and performance.

The data journey undertaken by the Expedia Group is probably similar to many others who have been operating in this space over the past two decades - scaling out from relational databases to on premise Hadoop clusters to a much wider ecosystem in the cloud. This talk will give an overview of that journey and then describe the various open source components that Expedia Group have used and built to create multi-petabyte data lakes. These include existing open source projects like Hive, Hadoop, Terraform, Docker, Kubernetes as well as open source tools that we built to overcome some of the unexpected challenges we faced. The first of these is Circus Train — a dataset replication tool that copies Hive tables between clusters and clouds. We will also discuss various other options for dataset replication and what unique features Circus Train has. The second tool is Waggle Dance — a federated Hive metadata service that enables querying of data stored across multiple Hive metastores. We will then look at Apiary - a means to simplify the deployment of the various components of an open source data lake at scale including the Hive metastore, Waggle Dance, S3 bucket access, metadata change notifications and much more.

However, in recent years, the hardware added new challenges that need to be addressed as well, demanding approaches that include the hardware into the picture. First, hardware is getting more and more heterogeneous and consists not only of general-purpose cores, but contains also various accelerators. Second, system designers need to integrate untrusted third-party components (e.g., accelerators or modems) to meet today's performance, energy, and development-time demands. And third, security vulnerabilities such as Meltdown, Spectre, and Fallout have shown that today's complex general-purpose cores should not be trusted anymore to properly enforce isolation boundaries between different software components.</p> <p>In my talk, I will present a new system architecture that takes existing microkernel ideas to the "next level" to address the mentioned challenges. We use a hardware/operating system co-design consisting of a small and simple hardware component, called <em>trusted communication unit</em> (TCU), that we add next to each processing element (core, accelerator, modem, etc.) and an operating system, called <em>M³</em>, that takes advantage of it. The TCU provides a uniform interface for all processing elements, simplifying the management and usage of heterogeneous processing elements, and enables secure communication between arbitrary processing elements. M³ is designed as a microkernel-based system and runs its components on different processing elements with TCU-based communication channels between them. To account for the security vulnerabilities in today's cores, M³ places components onto different and physically isolated processing elements by default, but allows sharing of processing elements as a fallback.</p> PUBLIC CONFIRMED Microkernels and Component-based OS https:/fosdem.org/2020/schedule/event/uk_m3/ K.4.601 Nils Asmussen PUBLISH 9411@FOSDEM20@pentabarf.org 9411 pwas_on_steroids pwas_on_steroids PWAs on steroids en en_US JavaScript 2020-02-02 10:00:00 +0100 2020-02-02 10:25:00 +0100 00:25:00:00 20200202T100000 20200202T102500 00:25:00:00 PWAs on steroids <p>PWAs bring the best of both mobile and native apps to user.

Originally focused on voice, aditionnal functionalities were rapidly added like video, group chat and presence. All of these communication modes imply privacy.</p> <p>To achieve a good level of privacy, users must be able to ensure that their communications can only be displayed to the receiver of those communications, especially no-one from server infrastructure crossed by the messages shall be in the position of compromising secrecy of the communication. Basically, this is what end-to-end encryption is aiming to achieve.</p> <p>Linphone does implement end-to-end encryption for voice and video communications thanks to ZRTP (rfc 6189). However, for messaging, security was only performed using point-to-point cyphering, based on SIP TLS. To bring users of instant messaging features the same level of security, we decided to implement end-to-end encryption mechanisms for messaging too, including group chat.

Carpenter of IAB and Fred Baker of IETF wrote a co-statement on cryptographic technology and the internet. This RFC wasn't a request for a technical standard, it was a statement on their concerns about Governments trying to restrict or interfere with cryptography. They felt that there was a need to offer "All Internet Users an adequate degree of privacy"</p> <p>Since that time successive governments around the world have sought to build back doors into encrypted apps and services to access more citizen and visitor data. As of July 2019, the AG of the United States William Barr stated: “Some argue that, to achieve at best a slight incremental improvement in security, it is worth imposing a massive cost on society in the form of degraded safety,” i.e For security Americans should accept weakened encryption. The head of the FBI also claimed that weakened encryption wouldn't break it. At the moment the US Government is actively trying to stop Facebook implementing end to end encryption across it's suite of apps.</p> <p>In Australia the metadata retention laws have been abused against journalists with 58 searches carried out by the AFP. In 2015 ACT police carried out 115 metadata searches. UK officials have a cavalier attitude to the EU SIS database which tracks undocumented migrants, missing people, stolen cars, or suspected criminals.</p> <p>The EU isn't immune to this either with France considering implementing Facial Recognition on its government services.</p> <p>IETF Session 105 mentioned privacy and concerns with the mass collection of data. While the IAB and IESG were worried about US export controls on cryptography there is an argument for RFC 1984 to be updated to include the unnecessary mass collection of data and to use it as a term for IT professionals, privacy advocates and the public to rally behind.</p> <p>In this talk let's recount a brief history of governments around the world wanting to weaken encryption as RFC 1984 warned us about.</p> <p>We live in a time where citizens put data into commercial, healthcare and Government systems to access services, some services are only accessible online. From CCTV to Facebook people have little understanding of why mass collection of data is dangerous. There is little scrutiny of who can access that data, from Scotland to the US.</p> <p>Open Surveillance is only a small part of the picture when profiling citizens. It still counts as personal data, when combined with metadata and the actual data that people put into social media and services like ancestor DNA test kits. Businesses who use CCTV have to put up signs to warn the public they are recording. So called anonymized data still contains identifiers that can tie to individuals.</p> <p>Let's talk about Ovid and peacocks. Let's explore how to expand the RFC to cover recent developments in surveillance capitalism with governments accessing that data, but not securing it. We need to make it clear weakened encryption, the mass collection and careless retention of data isn't acceptable. RFC1984 became Best Practice in 2015, we need to do more to raise awareness and to implement it in our projects.</p> PUBLIC CONFIRMED Decentralized Internet and Privacy https:/fosdem.org/2020/schedule/event/dip_rfc1984/ UA2.220 (Guillissen) Esther Payne PUBLISH 10351@FOSDEM20@pentabarf.org 10351 magic_castle magic_castle Magic Castle: Terraforming the Cloud for HPC en en_US HPC, Big Data, and Data Science 2020-02-02 10:00:00 +0100 2020-02-02 10:25:00 +0100 00:25:00:00 20200202T100000 20200202T102500 00:25:00:00 Magic Castle: Terraforming the Cloud for HPC <p>Compute Canada provides HPC infrastructures and support to every academic research institution in Canada. In recent years, Compute Canada has started distributing research software to its HPC clusters using with CERN software distribution service, CVMFS. This opened the possibility for accessing the software from almost any location and therefore allow the replication of the Compute Canada experience outside of its physical infrastructure.</p> <p>From these new possibilities emerged an open-source software project named Magic Castle, which aims to recreate the Compute Canada user experience in public clouds. Magic Castle uses the open-source software Terraform and HashiCorp Language (HCL) to define the virtual machines, volumes, and networks that are required to replicate a virtual HPC infrastructure. The infrastructure definition is packaged as a Terraform module that users can customize as they require. Once their cluster is deployed, the user is provided with a complete HPC cluster software environment including a Slurm scheduler, a Globus Endpoint, JupyterHub, LDAP, DNS, and over 3000 research software compiled by experts with EasyBuild. Magic Castle is compatible with AWS, Microsoft Azure, Google Cloud, OpenStack, and OVH.</p> <p>Compute Canada staff has been using this software to deploy ephemeral clusters for training purposes every other week for the past two years. Magic Castle is also gaining in popularity with HPC cluster users for development, testing, and continuous integration.</p> <p>In this talk, we will give a live demonstration of the creation of a cluster. We will present the architecture of Magic Castle, explain infrastructure and provisioning design, and present use cases. We will conclude by describing some of the challenges experienced while developing this novel usage of Terraform.</p> PUBLIC CONFIRMED HPC, Big Data, and Data Science https:/fosdem.org/2020/schedule/event/magic_castle/ UB5.132 Félix-Antoine Fortin PUBLISH 10453@FOSDEM20@pentabarf.org 10453 kotlin_migrating_fosdem_companion kotlin_migrating_fosdem_companion Migrating FOSDEM Companion to Kotlin en en_US Kotlin 2020-02-02 10:00:00 +0100 2020-02-02 10:25:00 +0100 00:25:00:00 20200202T100000 20200202T102500 00:25:00:00 Migrating FOSDEM Companion to Kotlin <p>FOSDEM Companion is currently the most used mobile application at FOSDEM.

They decided not to interveine and let the market fix the problem. Now, 9 years later, the market has made a mess out of it: there is no uniform way of exchanging medical data in The Netherlands. Architects write countless of pages with solutions, the government pours millions into subsidised programs, but the problem is only getting bigger.</p> <p>So, 2 years ago together with a group of other software vendors we started a foundation called Nuts. The goal is to end this impasse by building an open source decentralised infrastructure that nobody controls and can be used by everyone. It should be cheap to join, privacy by design, and use technology over lawyers.</p> <p>Our infrastructure allows parties to exchange data "peer to peer", only helping them solve four generic problems: user identity, patient consent, discovery of endpoints and logging.</p> <p>In this talk I would like to show our architecture, explain which choices we made, what we have learned while working with a distributed software and some anecdotes about what happens if you pitch such an idea to the establishment.</p> <hr /> <p>A little more background: I'm one of the main devs. The system is written mostly in Go and some parts in Java. Every software vendor can spin up a node and join the network. Patient Consents are distributed by a DLT (Corda) and are only stored on the nodes of vendors who already process the patient`s data. No medical data flows through the system, Nuts is only used to connect them and provide a level of trust. Identities are managed by a self-sovereign Identity system called IRMA (irma.app) which is based on IBM idemix.</p> PUBLIC CONFIRMED Decentralized Internet and Privacy https:/fosdem.org/2020/schedule/event/dip_fixing_healthcare_data/ UA2.220 (Guillissen) Steven van der Vegt PUBLISH 9278@FOSDEM20@pentabarf.org 9278 hfaf hfaf Homebrew: Features and Funding en en_US Distributions 2020-02-02 10:30:00 +0100 2020-02-02 10:55:00 +0100 00:25:00:00 20200202T103000 20200202T105500 00:25:00:00 Homebrew: Features and Funding <p>A talk about the Homebrew package manager and how we've been working with our users to introduce new features to subsets of users, encouraging users to donate to the project and communicating both these to as many users as possible without being annoying.</p> PUBLIC CONFIRMED Distributions https:/fosdem.org/2020/schedule/event/hfaf/ K.3.201 Mike McQuaid PUBLISH 9345@FOSDEM20@pentabarf.org 9345 openoffice_build_system openoffice_build_system Openoffice Build system A walk through building OpenOffice en en_US Open Document Editors 2020-02-01 10:30:00 +0100 2020-02-01 10:55:00 +0100 00:25:00:00 20200201T103000 20200201T105500 00:25:00:00 Openoffice Build system- A walk through building OpenOffice <p>This talk will be about the OpenOffice Build system.

We will focus on LLDB, the debugger, and sanitisers (e.g. AddressSanitizer and LeakSanitizer). No prior knowledge is required, but if you're familiar with GDB or Valgrind then this talk will introduce you to alternatives available within LLVM.</p> <p>LLDB is a very powerful and extensible command line debugger available on Linux, Mac OS, FreeBSD, Windows and Android. It is used internally in XCode and Android Studio and available on various hardware platforms (e.g. X86, ARM, AArch64, PowerPC, Mips). LLDB is built as a set of reusable components which highly leverage existing libraries in LLVM. It has a very powerful expression evaluation engine, intuitive CL interface (with tab-completion), easy to navigate help pages and a "graphical" user interface. In this presentation we will explore basic usage as well as some lesser known features. LLDB has come a long way and we want to present how intuitive, helpful and powerful it can be when used pragmatically.</p> <p>While LLDB will let you easily examine and debug a program at the point of failure, it can be harder to diagnose the underlying problem if it occurred before the program crashed or printed an incorrect result. LLVM provides some extra features in the form of 'sanitizers' to help find the root cause of some extra problems, like accessing a wrong-but-still-valid memory address or unintentionally wrapping a signed integer value. This presentation will explore how to use the sanitizers to debug programs and some examples of bugs they can catch.</p> PUBLIC CONFIRMED LLVM https:/fosdem.org/2020/schedule/event/debugging_with_llvm/ K.4.201 Andrzej Warzynski Graham Hunter PUBLISH 9814@FOSDEM20@pentabarf.org 9814 iotsphactor iotsphactor Sphactor: actor model concurrency for creatives Sphactor: actor model concurrency for creatives en en_US Internet of Things 2020-02-02 10:30:00 +0100 2020-02-02 10:50:00 +0100 00:20:00:00 20200202T103000 20200202T105000 00:20:00:00 Sphactor: actor model concurrency for creatives- Sphactor: actor model concurrency for creatives <p>We propose a combined visual and text-based programming environment based on the actor model suitable for novice to expert programmers.

It is based around the tenants of modularity, high availability, scalability, low-overhead networking, and ease of deployment. And a number of companies such as Google has shown that it is really possible to achieve these properties with it. But the architectural basis of cloud-native is quite different from the ones of virtualization-based NFV, but nevertheless, in many cases we continue to use the software packages that were designed for that drastically different architecture. The question is, how well does the current set of open source projects used in NFV work in a cloud-native environment and what needs to change in them in order to realize the cloud-native vision?</p> <p>In this presentation, I will define what I mean with cloud-native networking and from that derive the system requirements needed to realize that vision. Based on these requirements, we can deduce a number of basic architectural properties, features and services that are needed in the system to be able to satisfy these requirements. Then I will go through the most popular open source projects such as Linux, DPDK and OVS and see how they satisfy these architectural properties and features. The main contribution of this presentation will be to show what we need to work on within these SW packages in order to realize cloud-native networking.

It uses an in order 2 stage pipe and is best suited for area and power sensitive rather than high performance applications. However there is scope for meaningful performance gains without major impact to power or area. This talk describes work done at lowRISC to analyse and improve the performance of Ibex. The RTL of an Ibex system is simulated using Verilator to run CoreMark and Embench and the traces analysed to identify the major sources of stalls within them. This informs where improvements should be targeted. The open source implementation tools Yosys and openSTA are used to assess potential timing and area impacts of these improvements. In this talk you’ll learn about the pipeline of Ibex, methods to analyse the performance of CPU microarchitecture and how to use Yosys and openSTA to analyse what limits clock frequency in a design.</p> PUBLIC CONFIRMED RISC-V https:/fosdem.org/2020/schedule/event/riscv_lowrisc/ K.3.401 Greg Chadwick PUBLISH 10130@FOSDEM20@pentabarf.org 10130 tracing_ceph tracing_ceph Jaegertracing in Ceph An interesting case of distributed tracing en en_US Monitoring and Observability 2020-02-02 10:30:00 +0100 2020-02-02 10:55:00 +0100 00:25:00:00 20200202T103000 20200202T105500 00:25:00:00 Jaegertracing in Ceph- An interesting case of distributed tracing <p>Jaeger and Opentracing provide ready to use tracing services for distributed systems and are becoming widely used de-facto standard because of their ease of use.

It is an open ended language that inherits functionality from the target platform's development tools.</p></li> <li><p>seedForth (&lt;550 LOCs) a minimal stack based extensible programming system accepting tokenized source code. seedForth can be extended in various ways: as stand alone applications, as fully interactive systems, as umbilical target system for embedded system's programming</p></li> </ul> <p>We try to use Forth wherever possible in order to minimize semantic and formalism mismatches. Everything should be readily available - no hidden secrets.</p> <p>Of course many of the subjects we are looking at have been used by others in the Forth community and outside - we are dwarfs standing on the shoulders of giants - however we believe our new synthesis to be original.</p> PUBLIC CONFIRMED Minimalistic, Experimental and Emerging Languages https:/fosdem.org/2020/schedule/event/forth_new_synthesis/ AW1.125 Ulrich Hoffmann PUBLISH 10255@FOSDEM20@pentabarf.org 10255 containers_podman containers_podman Podman - The Powerful Container Multi-Tool An use case driven hands-on to the container management tool Podman en en_US Containers 2020-02-01 10:30:00 +0100 2020-02-01 10:50:00 +0100 00:20:00:00 20200201T103000 20200201T105000 00:20:00:00 Podman - The Powerful Container Multi-Tool- An use case driven hands-on to the container management tool Podman <p>Podman is the container management tool of your choice when it comes to boosting day-to-day development tasks around containers.

Building up from conversations we had with other designers moving in the sphere of Libre Software and Libre Culture, we want to: - present terms and try to define their scope in the hopes of improving the ways in which open design can be explained to others - distinguish between possible stances inside the sphere of open design, such as using libre tools vs. proprietary toolchains, designing for free software vs. designing with free software - explore how we understand other designers/studios/communities' ideas and practices - better understand how we can present our views and work vis-à-vis other design approaches -- especially to "traditional" and proprietary-oriented audiences</p> <p>This talk is a follow-up to "Open Design, Libre Graphics: Why terminology matters", that we presented at Libre Graphics Meeting 2019.

Also sightseeing? Geocaching? Tried to optimize your way along the sights or to find many caches without making it a hike? Then you've got the traveling salesman problem! Famous in computer science because finding the optimum is extremely difficult and finding good approximations can be done easily.</p> <p>Last year we had a talk about 3geonames.org where the Hilbert curve was mentioned to be used in name generation. When researching about this space curve it turned out that such space filling curves give good approximations for the traveling salesman problem. This has already been evaluated scientifically. Route finding using thees curves is extremely simple. Other algorithms need much more computational effort. Using a space filling curve to find a route proposal and improving it with 2-Opt optimization algorithm gives the quality of 2-Opt at high speed. Even so fast that it keeps track with interactive changes of the waypoints on a moving map display.</p> <p>This mechanism gives short routes for your sightseeing or geocaching planning and can also be used professionally if you have to visit several locations on a single tour as in package delivery, meals on wheels, or elderly care.</p> PUBLIC CONFIRMED Geospatial https:/fosdem.org/2020/schedule/event/getting_inspired_by_open_software_for_a_web_site_g3nfyi/ AW1.126 Thomas Bremer PUBLISH 10534@FOSDEM20@pentabarf.org 10534 xmpp xmpp XMPP: get your shopping cart ready!

There is also much talk about maintainer burn out and community exploitation. However, the same people who talk about this still paraphrase the most famous quote from the Cathedral and the Bazaar "Scratching your own itch". They forget this is your own itch not everyone else's because Open Source begins as a selfish activity. The fact that communities do form around a load of selfish competing individuals is actually a testament to the unacknowledged power of open source to co-opt the selfish instinct and make it synergistic to some communal good.</p> <p>This talk will explore the selfish origins of free and open source and dissect the co-option power it has to form broad and deep communities from what are apparently simple transactional engagements. We'll also explain how some of the more recent community failures have been engendered by the concentration on long term community to the detriment of enabling purely transactional mechanics by which initially selfish contributors come to the project.</p> PUBLIC CONFIRMED Community and Ethics https:/fosdem.org/2020/schedule/event/selfish_contributor/ K.1.105 (La Fontaine) James Bottomley PUBLISH 9284@FOSDEM20@pentabarf.org 9284 uk_linux uk_linux Linux Kernel Library A Library Version of Linux Kernel en en_US Microkernels and Component-based OS 2020-02-02 11:00:00 +0100 2020-02-02 11:25:00 +0100 00:25:00:00 20200202T110000 20200202T112500 00:25:00:00 Linux Kernel Library- A Library Version of Linux Kernel <p>LKL (Linux Kernel Library) is aiming to allow reusing the Linux kernel code as extensively as possible with minimal effort and reduced maintenance overhead.

Apache Beam’s Stateful Stream processing capabilities are a perfect match here including support for scalable Weak Supervision.</p> <p>Prior work on using Beam’s State coupled with Flink’s dynamic processing capabilities to store and update word embeddings for real-time Online Topic Modeling of text has been presented at Flink Forward Berlin 2018. Similar streaming pipelines would also work for real-time model updates using Weak Supervision and Transfer Learning. In this talk, we’ll be looking at a framework - Snorkel BeamBell - a framework leveraging Stanford’s Snorkel library for Weak Supervision and Apache Beam for large scale Weak Supervision Learning for online labeling of large amounts of data that can continuously learn new classification models based on Stateful Learning Functions and user feedback.</p> PUBLIC CONFIRMED HPC, Big Data, and Data Science https:/fosdem.org/2020/schedule/event/snorkel_beambell/ UB5.132 Suneel Marthi PUBLISH 10046@FOSDEM20@pentabarf.org 10046 heptapod_mercurial heptapod_mercurial The Heptapod project Bringing Mercurial to GitLab en en_US Lightning Talks 2020-02-02 11:00:00 +0100 2020-02-02 11:15:00 +0100 00:15:00:00 20200202T110000 20200202T111500 00:15:00:00 The Heptapod project- Bringing Mercurial to GitLab <p>Heptapod is a friendly fork of GitLab CE that supports the Mercurial DVCS.

In the former industry setting modern team development tools and methods are used (version control, continuous integration, Scrum, ...) to develop software in teams with a focus on the final software product. In contrast, in the latter scientific environment a large fraction of scientific code is produced by individual scientists lacking thorough training in software development with a specific research goal in mind. Indeed, it is only in the last decades that scientific software development started to become a fully recognized part of scientific work. Still, formal training in software development is largely missing in the scientific curricula of many universities. Additionally, due to the exploratory nature of the scientific method at the frontier of knowledge, most projects require the implementation of custom code. The combination of these circumstances promotes the development of scientific code not suited for sharing and long term maintenance, limiting the reusability and reproducibility of scientific data and findings. The systematic development and adoption of open source packages by the scientific community can emend this situation. Here we present examplary open source packages from the field of neuroscience and discuss the special requirements for open source software development and services in this research area.</p> <p>Acknowledgements: This project has received funding from the European Union’s Horizon 2020 Framework Programme for Research and Innovation under Specific Grant Agreement No. 785907 (Human Brain Project SGA2).

ReaR can store the details about your systems on disks (NAS, USB, SAN,...) or network (PXE, NFS, CIFS,...) including the complete backup. It also creates a bootable image which you need to recreate your system from scratch. Furthermore, thanks to the modular concept, ReaR integrates perfectly with external backup solutions (be commercial and/or open source ones) to do the backup and restore part which makes ReaR very scalable in big enterprises.

Formal methods could improve the situation, but program verification remains a complex and time-consuming task. Often, the verification of existing software is infeasible and a complete rewrite can be prohibitively expensive. Both, however, is not necessarily required to improve on the current state. By replacing critical parts of an existing software by verified code, security can be strengthened significantly with moderate effort.</p> <p>We show the feasibility of this approach by the example of a FLOSS TLS implementation. The basis of our PoC is the TLS 1.3 library <a href="https://github.com/facebookincubator/fizz">Fizz</a> which is written in C++. The existing message parser was replaced by a verified version implemented in the <a href="https://www.adacore.com/about-spark">SPARK</a> language. Our <a href="https://github.com/Componolit/RecordFlux">RecordFlux</a> toolset was used to automatically generate the parser based on a formal message specification. With the SPARK tools we can prove automatically that an attacker cannot cause any overflows, runtime errors or undefined state by sending malformed messages to the modified library. Because of mismatches in the data structures used in C++ and SPARK, some glue code had to be written manually to integrate the verified parser into Fizz. Still, the modified TLS implementation shows only a slight performance loss while providing higher security.</p> PUBLIC CONFIRMED Security https:/fosdem.org/2020/schedule/event/security_securing_existing_software_using_formally_verified_libraries/ UA2.114 (Baudoux) Tobias Reiher PUBLISH 10315@FOSDEM20@pentabarf.org 10315 coverity_and_ossfuzz_issue_solving coverity_and_ossfuzz_issue_solving coverity and oss-fuzz issue solving common patterns for solving reported issues en en_US Open Document Editors 2020-02-01 11:30:00 +0100 2020-02-01 11:55:00 +0100 00:25:00:00 20200201T113000 20200201T115500 00:25:00:00 coverity and oss-fuzz issue solving- common patterns for solving reported issues PUBLIC CONFIRMED Open Document Editors https:/fosdem.org/2020/schedule/event/coverity_and_ossfuzz_issue_solving/ UB4.136 Caolán McNamara PUBLISH 10343@FOSDEM20@pentabarf.org 10343 kotlin_missing_asyncronism_with_coroutines kotlin_missing_asyncronism_with_coroutines AMENDMENT Modern asynchronism with coroutines Presentation and best practices of the coroutines framework en en_US Kotlin 2020-02-02 11:30:00 +0100 2020-02-02 11:55:00 +0100 00:25:00:00 20200202T113000 20200202T115500 00:25:00:00 AMENDMENT Modern asynchronism with coroutines- Presentation and best practices of the coroutines framework <p>Presentation of Kotlin Coroutines, a great new framework for asynchronism which makes it more powerfull and easier to manage.</p> <p><em>Please note that this talk replaces one entitled "Experimenting with the Kotlin Compiler" that was due to have been given by Jossi Wolf, who has sent his apologies but is now unable to attend as he has fallen ill.

By embracing open source, standards orgs benefit from the speed and collaborative spirit of open source and get timely feedback on the clarity and correctness of standards as they evolve in parallel with running code. Open source communities gain users, address additional use cases, and gain the stability of standards to ease integration efforts and avoid forks.

However, while accelerator “sockets” have been defined and used (e.g., Rocket Chip’s custom coprocessor/RoCC), accelerators require <em>additional</em> collateral to be generated like structured metadata descriptions, hardware wrappers, and device drivers. Requiring manual effort to generate this collateral proves both time consuming and error prone and is at odds with an agile approach to hardware design. However, the existence and use of hardware construction languages and hardware compilers provides a means to automate this process. Through the use of the Chisel hardware description language [4] and the FIRRTL hardware compiler [5], we provide a definition of an abstract accelerator template which users then implement to integrate an accelerator with the Embedded Scalable Platform (ESP) System-on-Chip platform [2, 8]. Through the use of this template, we are able to automatically generate XML metadata necessary to integrate accelerators with the ESP platform and work on generating all collateral is in progress.

On the other hand, living organisms like strawberry plants draw their own observability requirements, such as disease detection, physiological measurements, nutrient absorption, water analysis, or exposition rate to pollinating bumblebees.</p> <p>The purpose of this talk is to highlight observability challenges and best practices that are specific to indoor farming, and to illustrate them through the learnings that were made at Agricool when building observability pipelines.</p> PUBLIC CONFIRMED Monitoring and Observability https:/fosdem.org/2020/schedule/event/strawberries/ UD2.120 (Chavanne) Jean-Marc Davril PUBLISH 10720@FOSDEM20@pentabarf.org 10720 tornadovm tornadovm TornadoVM: A Virtual Machine for Exploiting ​High-Performance Heterogeneous ​Execution of Java Programs​ en en_US Free Java 2020-02-01 11:50:00 +0100 2020-02-01 12:15:00 +0100 00:25:00:00 20200201T115000 20200201T121500 00:25:00:00 TornadoVM: A Virtual Machine for Exploiting ​High-Performance Heterogeneous ​Execution of Java Programs​ <p>The proliferation of heterogeneous hardware in recent years has driven us to consider that every system we program, most likely includes a mix of computing elements; each of which with different hardware characteristics enabling programmers to improve performance while reducing energy consumption. These new heterogeneous devices include multi-core CPUs, GPUs and FPGAs. This trend has been accompanied by changes in software development norms that do not necessarily favor programmers. A prime example is the two most popular heterogeneous programming languages, CUDA and OpenCL, which expose several low-level features to the API making them difficult to use by non-expert users.</p> <p>Instead of using low-level programming languages, developers in industry and academia tend to use higher-level, object-oriented programming languages, typically executed on managed runtime environments, such as Java, R, and Javascript. Although many programmers might expect that such programming languages would have already been adapted for transparent execution on heterogeneous hardware, the reality is that their support is either very limited or absent.</p> <p>In this talk, we present TornadoVM (https://github.com/beehive-lab/TornadoVM), a heterogeneous programming framework for Java programs. TornadoVM co-exists with standard JVMs (e.g., OpenJDK) that implement the JVMCI. TornadoVM consists of three components: 1) a simple API for composing pipelines of existing Java methods, 2) an optimizing JIT compiler that extends the Graal compiler with hardware-aware optimizations that generate OpenCL C code, and 3) a runtime system that executes TornadoVM specific bytecodes, performs memory management, and schedules the code for execution on GPUs, multicore CPUs, and FPGAs. Essentially, TornadoVM is a “VM-in-a-VM” that can adapt execution completely dynamically and transparently to the user, always finding the highest-performing combination of hardware accelerators through dynamic reconfiguration.</p> PUBLIC CONFIRMED Free Java https:/fosdem.org/2020/schedule/event/tornadovm/ H.1302 (Depage) Thanos Stratikopoulos PUBLISH 10769@FOSDEM20@pentabarf.org 10769 quantum_computing_hardware_and_control_systems quantum_computing_hardware_and_control_systems Quantum computing hardware and control systems en en_US Quantum Computing 2020-02-01 11:50:00 +0100 2020-02-01 12:25:00 +0100 00:35:00:00 20200201T115000 20200201T122500 00:35:00:00 Quantum computing hardware and control systems PUBLIC CONFIRMED Quantum Computing https:/fosdem.org/2020/schedule/event/quantum_computing_hardware_and_control_systems/ UA2.118 (Henriot) Felix Tripier PUBLISH 9235@FOSDEM20@pentabarf.org 9235 cognitivebias cognitivebias Cognitive biases, blindspots and inclusion en en_US Community devroom 2020-02-02 11:55:00 +0100 2020-02-02 12:20:00 +0100 00:25:00:00 20200202T115500 20200202T122000 00:25:00:00 Cognitive biases, blindspots and inclusion <p>Open source thrives on diversity.

The protocol is extremely lightweight, decentralised, and its speed and load per node do not depend on cluster size.</p> <p>The protocol solves several tasks at once. First - build and keep up to date topology of a cluster without explicit configuration. The task is quite intricate because:</p> <ul> <li>new just started nodes know nothing about others, and they should somehow discover them;</li> <li>already working nodes can fail, and it should be detected so as to change a master, or evict an unrecoverable node from the cluster, or restart it.</li> </ul> <p>According to the protocol, cluster nodes broadcast packets and send p2p ping requests. Broadcast helps to discover new nodes, p2p pings help to detect failure of a known node.</p> <p>A second task - events dissemination in a cluster. Event is a node failure; UUID change; IP address update; new node appearance - anything that affects cluster state. Sometimes users define their own event types. When a node learns about an event, it needs to disseminate the event to other nodes. SWIM protocol describes an algorithm how to detect and disseminate events, and gives the following guarantees:</p> <ul> <li>it takes a constant time to learn about an event on at least one node in the cluster;</li> <li>it takes logarithmic from cluster size time to disseminate that event to each node of the cluster.</li> </ul> <p>In the talk I tell about how SWIM works, how and with which essential improvements it was implemented, how to use SWIM, and what are the practical performance results.</p> <p>Implementation is a part of Tarantool DBMS. Tarantool is the biggest Russian Open-Source DBMS. Tarantool currently goes toward better scalability, improvements in horizontal scaling, in cluster-wide calculations, and better cluster management.

The market is dominated by vendors offering monolithic and proprietary software due to the critical nature of the supported processes and - in some cases - due to legal requirements. The “digital transformation”, “big data” and “artificial intelligence” are some of the hypes that demand for improved exchange of health care data in routine health care and medical research alike. Exchanging data at these scales requires open data formats and protocols, multi-stakeholder collaboration, and agile development. As an example, the de-facto messaging standard organization in medicine HL7 noticed a much more positive response from the medical research community regarding their openly available FHIR specification in comparison to the for-members-only and XML-based HL7v3 messaging standard specification. While some past (or rather: ongoing) projects on a national scale in the German health care system have tried centralized, top-down specification and development approaches, more recent infrastructure projects embrace the competitive collaboration of a decentralized, bottom-up strategy. As a result, importance and recognition of free software increase in the Medical Informatics research community.</p> <p>In a series of rapid spotlights, we present tools and frameworks that serve as cornerstones for the envisioned health data exchange infrastructure, including: Organization and collaboration tools; data extraction from clinical source systems, data transformation and de-identification; data management systems and long-term archival using persistent globally-unique object identifiers; federated queries across multiple independently managed clinical data integration centers.</p> <p>We aim to encourage participants to actively add tools and frameworks within the discussion and highlight their experiences and challenges with using open systems in Medical Informatics.</p> PUBLIC CONFIRMED Open Research Tools and Technologies https:/fosdem.org/2020/schedule/event/open_research_secure_health_data/ AW1.126 Markus Suhr Marcel Parciak PUBLISH 10463@FOSDEM20@pentabarf.org 10463 vai_lightweight_virt_at_the_edge vai_lightweight_virt_at_the_edge Lightweight virtualization in the Cloud and at the Edge hypervisors gone rogue en en_US Virtualization and IaaS 2020-02-02 12:00:00 +0100 2020-02-02 12:30:00 +0100 00:30:00:00 20200202T120000 20200202T123000 00:30:00:00 Lightweight virtualization in the Cloud and at the Edge- hypervisors gone rogue <p>Running applications in the Cloud has changed the way users develop and ship their code. Quite recently, the community has given rise to microservices-based approaches, towards solutions that follow the paradigm of Platform-, Software-, and Function-as-a-Service (PaaS, SaaS, and FaaS respectively).</p> <p>To accommodate user demands, while maintaining security and isolation, Cloud vendors have adopted a hybrid approach where user workloads are being executed in lightweight sandboxed environments, where micro-hypervisors provide the isolation and container-based images facilitate application deployment. As a result, lighter virtualization stacks remains a key aspect to maximize performance in a multi-tenant but isolated environment.</p> <p>To this end, we started experimenting with various Virtual Machine Monitors (VMMs) that could provide the ideal trade-off between performance, flexibility and application portability. In this talk, we present the design of a minimal VMM, based on KVM, residing entirely in the Linux Kernel and showcase the merits and shortcomings (minimal footprint, security concerns), for each use-case (Cloud FaaS, edge multi-tenancy).

To take advantage of these fully, users need to understand the basic concept of indexes, to be able to compare the different index types and how they apply to different application scenarios. Only then can you make an informed decision about your database index strategy and design. One thing is for sure: not all indexes are appropriate for all circumstances, and using a ‘wrong’ index can have the opposite effect that you intend and problems might only surface once in production. Armed with more advanced knowledge, you can avoid this worst-case scenario! We’ll take a look at how to use pg<em>stat</em>statment to find opportunities for adding indexes to your database. We’ll take a look at when to add an index, and when adding an index is unlikely to result in a good solution. So should you add an index to every column?

In processing systems ranging from connected cars and autonomous vehicles, to those on-board satellites and spacecrafts, these processors are targeted to function in safety-critical systems, where Reliability, Availability and Serviceability (RAS)-based considerations are of paramount importance. Along with potential system vulnerabilities caused primarily due to random errors, these processors may also be sensitive to targeted errors, possibly from malicious entities, which raises serious concerns regarding the security and safety of the processing system. Consequently, such systems necessitate the incorporation of RAS-based considerations right from an early stage of processor design.</p> <p>While the hardware and software ecosystem around RISC-V has been steadily maturing, there have, however, been limited developments in early stage reliability-aware design and verification. The Early-stage Reliability And Security Estimation for RISC-V (ERASER) tool attempts to address this shortcoming. It consists of an open source framework aimed at providing directions to incorporate such reliability and security features at an early, pre-silicon stage of design. These features may include what kind of protection to be applied and which components within the processor should they be applied to. The proposed infrastructure comprises of an open source toolchain for early stage modeling of latch vulnerability in a RISC-V core (SERMiner [1]), a tool for automated generation of stress marks that maximize the likelihood of a transient-failure induced error (Microprobe (RISC-V) [2]), and verification by means of statistical and/or targeted fault injection (Chiffre [3]). While the infrastructure is targeted towards any core that uses the RISC-V ISA, the repository provides an end-to-end flow for the Rocket core [4].</p> <p>ERASER thus evaluates “RAS-readiness”, or the effectiveness of protection techniques in processor design such that processor vulnerability in terms of Failures-In-time (FIT) rate is minimized, for a specified power/performance overhead. FIT rate is defined as the number of failures in one billion hours of operation and is a standard vulnerability metric used in industry.</p> <p>ERASER is an open source tool available for download at https://github.com/IBM/eraser. The tool currently supports analysis of all latches in the design across a single Rocket core and the generation of stressmarks that can be used to evaluate the vulnerability of these latches. In addition to radiation-induced soft errors, we plan to extend ERASER to also model errors due to voltage noise, thermal and aging-induced failures, both in memory and logic, and generate representative stressmarks.</p> <p>ERASER is an initial effort to devise a comprehensive methodology for RAS analysis, particularly for open-source hardware, with the hope that it spurs further research and development into reliability-aware design both in industry and academia.</p> <p>References:</p> <ol> <li><p>K.

At the heart of the performance gain, eBPF (extended Berkeley Packet Filter) and XDP (eXpress Data Path) have brought new possibilities in terms of tracing and network packet processing. eBPF is a trendy topic in the Linux world, and today it needs little introduction among the SDN and NFV community. But the technology is still under heavy development, bringing new features, more flexibility, and better performance to the users. This presentation is an update on the latest evolutions in the eBPF world!</p> <p>Many of those changes occur directly inside the eBPF subsystem architecture. New program types are being added. Early constraints such as the maximal number of instructions for programs, or the unavailability of loops, are changing. The internals are improved with support for debug information (BTF) or 32-bit instructions. And many new mechanisms are implemented, such as global data support, the “BPF trampoline”, batched map operations, dynamic linking. Let's review all the latest trends in eBPF kernel development!</p> <p>But beyond kernel code, eBPF has grown as a full ecosystem, with a variety of tools used to work with it, or to build upon it. Bpftool, a reference utility to manage eBPF programs, keeps evolving. The networking projects using eBPF keep growing in number (e.g. Katran, Suricata, Sysdig, Hubble, Libkefir) or in features (e.g. Cilium). Let's review (briefly) some of those projects that assert eBPF as one of the essential fast dataplane solutions in the Linux world.</p> PUBLIC CONFIRMED Software Defined Networking https:/fosdem.org/2020/schedule/event/endless_network_programming/ H.1308 (Rolin) Quentin Monnet PUBLISH 10699@FOSDEM20@pentabarf.org 10699 bareosintro bareosintro Overview of Bareos What is Bareos and what is new in 19.2? en en_US Backup and Recovery 2020-02-01 12:10:00 +0100 2020-02-01 12:35:00 +0100 00:25:00:00 20200201T121000 20200201T123500 00:25:00:00 Overview of Bareos- What is Bareos and what is new in 19.2? <p>This talk will give quick overview of Bareos and the new features in Bareos 19.2.</p> PUBLIC CONFIRMED Backup and Recovery https:/fosdem.org/2020/schedule/event/bareosintro/ UD2.119 Andreas Rogge PUBLISH 10741@FOSDEM20@pentabarf.org 10741 discover_the_new_firefox_profiler discover_the_new_firefox_profiler Discover the New Firefox Profiler en en_US Mozilla 2020-02-02 12:15:00 +0100 2020-02-02 12:40:00 +0100 00:25:00:00 20200202T121500 20200202T124000 00:25:00:00 Discover the New Firefox Profiler <p>Using a profiling tool help developers to get detailed information about the execution of their application and allow them to understand the behavior of it.</p> <p>The Firefox Profiler is a profiler that is built into Firefox.

All those things are closely related and affect each other.</p> <p>We'll discuss different deployment strategies and answer a couple of questions. Is your application stateful or stateless? Does its architecture permit scaling? How do you roll back? How do you scale up and down? Do you need your application to run always? Should you use Kubernetes Deployments instead of, let's say, StatefulSets? Answers to those questions will not serve much unless we are familiar with some of the most commonly used deployment strategies. Not only that knowledge will help us choose which one to pick, but they might even influence the architecture of our applications.</p> PUBLIC CONFIRMED Continuous Integration and Continuous Deployment https:/fosdem.org/2020/schedule/event/choosing_the_right_deployment_strategy/ UB4.136 Viktor Farcic PUBLISH 9653@FOSDEM20@pentabarf.org 9653 rook_cloud_native_storage_for_kubernetes rook_cloud_native_storage_for_kubernetes AMENDMENT Rook Cloud Native Storage for Kubernetes Overview and what is new about Rook en en_US Software Defined Storage 2020-02-02 12:20:00 +0100 2020-02-02 12:55:00 +0100 00:35:00:00 20200202T122000 20200202T125500 00:35:00:00 AMENDMENT Rook Cloud Native Storage for Kubernetes- Overview and what is new about Rook <p>What is Rook and the architecture of Rook + the storage run in Kubernetes.

The overarching design goal is to be extremely fluent and as close as possible to the design intent. CQ is based on the open source CAD kernel from OpenCascade and therefor offers industry standard B-Rep modeling capabilities and allows exporting to lossless formats such as STEP as well as lossy ones such as STL. Originally it used Python bindings based on FreeCAD [2] but recently we switched to PythonOCC [3] to be more flexible and have full access to the underlying CAD kernel capabilities. In the talk I will summarize the current status of the CQ project, show some interesting usage examples and discuss newly implemented features. Furthermore I will elaborate on the future plans of the core development team and touch on some of the challenges of maintaining a project such as CQ. I will also present a fairly new addition to the CQ ecosystem – CQ-editor [3]. It is a Python/PyQt5 based lightweight cross-platform GUI editor that allows to quickly develop and preview CQ 3D models. It also offers graphical debugging and CQ stack introspection capabilities which dramatically lowers the entry barrier for trying out and using CQ.</p> <p>References</p> <p>[1] https://github.com/CadQuery/cadquery [2] https://www.freecadweb.org [3] https://github.com/tpaviot/pythonocc-core [4] https://github.com/CadQuery/CQ-editor</p> PUBLIC CONFIRMED Open Source Computer Aided Modeling and Design https:/fosdem.org/2020/schedule/event/cadquery/ H.2213 Adam Urbanczyk PUBLISH 9953@FOSDEM20@pentabarf.org 9953 openolitor_community_supported_agriculture openolitor_community_supported_agriculture A tool for Community Supported Agriculture (CSA) management, OpenOlitor en en_US Lightning Talks 2020-02-01 12:20:00 +0100 2020-02-01 12:35:00 +0100 00:15:00:00 20200201T122000 20200201T123500 00:15:00:00 A tool for Community Supported Agriculture (CSA) management, OpenOlitor <p>OpenOlitor is a SaaS open-source tool facilitating the organization and management of CSAs (Community Supported Agriculture) communities.

Goavec-Merou, P.-Y. Bourgeois, J.-M. Friedt <p>Combining the flexibility of FPGA hardware configuration with the high abstraction level of an operating system running on a general purpose central processing unit (CPU) requires mastering a broad range of knowledge, from low level hardware configuration to kernel drivers to libraries and userspace application. While some vendor specific frameworks tackle the challenge, we focus on a vendor independent solution applicable to current FPGA Systen on Chip providers: the OscImp Digital framework provides a comprehensive set of FPGA IP, associated Linux driver, library and userspace examples based on GNU Radio running on the embedded CPU. We demonstrate its use on the Redpitaya platform processing baseband signals as well as the Zynq, most significantly associated with the AD9363 radiofrequency frontend on the PlutoSDR board. In both cases, the FPGA is not only used to stream I/Q coefficients but pre-process the datastream in order to reduce bandwidth and efficiently feed the CPU: we demonstrate embedded FM broadcast radio reception as well as GPS decoding on the PlutoSDR custom bitstream.

In this talk, we will give an accelerated tutorial on how to get started with OpenPiton+Ariane, the spec-compliant RISC-V platform it offers, and how the firmware and OS can be modified and run on top. We will show a number of applications built and running for our present Debian distribution and the software development environment that this offers. We will then highlight how hardware and software can be co-designed on OpenPiton+Ariane with the ability to recompile the hardware underlying the cloud FPGA image and deploy it for use by others.

Merely providing file access is insufficient for a simple reason: data are not static. Data often (and should!) continue to evolve; file formats can change, bugs will be fixed, new data are added, and derived data needs to be integrated. While (distributed) version control systems are a de-facto standard for open source software development, a similar level of tooling and culture is not present in the open data community.</p> <p>The lecture introduces DataLad, a software that aims to address this problem by providing a feature-rich API (command line and Python) for joint management of all digital objects of science: source code, data artifacts (as much as their derivatives), and essential utilities, such as container images of employed computational environments. A DataLad dataset represents a comprehensive and actionable unit that can be used privately, or be published on today's cyberinfrastructure (GitLab, GitHub, Figshare, S3, Google Drive, etc.) to facilitate large and small-scale collaborations.</p> <p>In addition to essential version control tasks, DataLad aids data discovery by supporting a plurality of evolving metadata description standards. Moreover, Datalad is able to capture data provenance information in a way that enables programmatic re-execution of computations, and as such provides a key feature for the implementation of reproducible science. DataLad is extensible and customizable to fine tune its functionality to specific domains (e.g., field of science or organizational requirements).</p> <p>DataLad is built on a few key principles:</p> <ol> <li><p><strong>DataLad only knows about two things: Datasets and files.</strong> A DataLad dataset is a collection of files in folders. And a file is the smallest unit any dataset can contain. At its core, <strong>DataLad is a completely domain-agnostic, general-purpose tool to manage data</strong>.</p></li> <li><p><strong>A dataset is a Git repository</strong>. A dataset is a Git repository. All features of the version control system Git also apply to everything managed by DataLad.</p></li> <li><p><strong>A DataLad dataset can take care of managing and version controlling arbitrarily large data</strong>. To do this, it has an optional <em>annex</em> for (large) file content: Thanks to this annex, DataLad can track files that are TBs in size (something that Git could not do, and that allows you to restore previous versions of data, transform and work with it while capturing all provenance, or share it with whomever you want). At the same time, DataLad does all of the magic necessary to get this important feature to work quietly in the background. The annex is set-up automatically, and the tool <a href="https://git-annex.branchable.com">git-annex</a> manages it all underneath the hood.</p></li> <li><p>DataLad follows the social principle to <strong>minimize custom procedures and data structures</strong>. DataLad will not transform your files into something that only DataLad or a specialized tool can read. A PDF file (or any other type of file) stays a PDF file (or whatever other type of file it was) whether it is managed by DataLad or not. This guarantees that users will not loose data or data access if DataLad would vanish from their system, or even when DataLad would vanish from the face of Earth. Using DataLad thus does not require or generate data structures that can only be used or read with DataLad -- DataLad does not tie you down, it liberates you.</p></li> <li><p>Furthermore, DataLad is developed for <strong>complete decentralization</strong>. There is no required central server or service necessary to use DataLad. In this way, no central infrastructure needs to be maintained (or paid for) -- your own laptop is the perfect place to live for your DataLad project, as is your institutions webserver, or any other common computational infrastructure you might be using.</p></li> <li><p>Simultaneously, though, DataLad aims to <strong>maximize the (re-)use of existing 3rd-party data resources and infrastructure</strong>. Users <em>can</em> use existing central infrastructure should they want to. DataLad works with any infrastructure from GitHub to Dropbox, Figshare, or institutional repositories, enabling users to harvest all of the advantages of their preferred infrastructure without tying anyone down to central services.</p></li> </ol> PUBLIC CONFIRMED Open Research Tools and Technologies https:/fosdem.org/2020/schedule/event/open_research_datalad/ AW1.126 Michael Hanke PUBLISH 10452@FOSDEM20@pentabarf.org 10452 coreboot_amd coreboot_amd Status of AMD platforms in coreboot en en_US Hardware Enablement 2020-02-02 12:30:00 +0100 2020-02-02 12:55:00 +0100 00:25:00:00 20200202T123000 20200202T125500 00:25:00:00 Status of AMD platforms in coreboot <p>The presentation is about AMD's involvement in coreboot evolution and development.

With just 20 lines of code we can build a connected lightbulb, and within seconds we can wirelessly deploy it. Write a couple of lines more, and you can even remotely control a car.

Considerable research and industry effort has gone into developing TEE runtime libraries with the purpose of transparently shielding enclave application code from an adversarial environment. However, our analysis reveals that shielding requirements are generally not well-understood in real-world TEE runtime implementations. We expose several sanitization vulnerabilities at the level of the Application Binary Interface (ABI) and the Application Programming Interface (API) that can lead to exploitable memory safety and side-channel vulnerabilities in the compiled enclave. Mitigation of these vulnerabilities is not as simple as ensuring that pointers are outside enclave memory. In fact, we demonstrate that state-of-the-art mitigation techniques such as Intel’s edger8r, Microsoft’s “deep copy marshalling”, or even memory-safe languages like Rust fail to fully eliminate this attack surface. Our analysis reveals 35 enclave interface sanitization vulnerabilities in 8 major open-source shielding frameworks for Intel SGX, RISC-V, and Sancus TEEs. We practically exploit these vulnerabilities in several attack scenarios to leak secret keys from the enclave or enable remote code reuse. We have responsibly disclosed our findings, leading to 5 designated CVE records and numerous security patches in the vulnerable open-source projects, including the Intel SGX-SDK, Microsoft Open Enclave, Google Asylo, and the Rust compiler.</p> <p>Please note that this talk was originally scheduled to begin at the later time of 13:00</p> PUBLIC CONFIRMED Hardware-aided Trusted Computing https:/fosdem.org/2020/schedule/event/tale/ K.4.601 Jo Van Bulck PUBLISH 10700@FOSDEM20@pentabarf.org 10700 bareosovirt bareosovirt oVirt-Plugin for Bareos Backing up oVirt using Bareos en en_US Backup and Recovery 2020-02-01 12:40:00 +0100 2020-02-01 12:55:00 +0100 00:15:00:00 20200201T124000 20200201T125500 00:15:00:00 oVirt-Plugin for Bareos- Backing up oVirt using Bareos <p>Backing up virtual machines in larger environments is usually not a simple task.

Software installation brings forth many challenges that requires a team of domain expertise and countless hours troubleshooting to build an optimal software state that is tuned to the architecture. In the past decade, two software build tools (Easybuild, Spack) have emerged that are widely accepted in HPC community to accelerate building a complete software stack for HPC systems. The support team are constantly involved in fulfilling software request for end-users which leads to an ever-growing software ecosystem. Once a software is installed, the support team hands it off to the user without any testing because scientific software requires domain expertise in order to test software. Some software packages are shipped with a test suite that can be run at post build while many software have no mechanism for testing. This poses a knowledge gap between HPC support team and end-users on the type of testing to do. Some HPC centers may have developed in-house test scripts that are suitable for testing their software, but these tests are not portable due to hardcoded paths and are often site dependent. In addition, there is no collaboration between HPC sites in building a test repository that will benefit the community. In this talk I will presents buildtest, a framework to automate software testing for a software stack along with several module operations that would be of interest to the HPC support team.</p> PUBLIC CONFIRMED HPC, Big Data, and Data Science https:/fosdem.org/2020/schedule/event/buildtest/ UB5.132 Shahzeb Siddiqui PUBLISH 10106@FOSDEM20@pentabarf.org 10106 webrtc_misc webrtc_misc WebRTC isn't just for (video) conference calls en en_US Real Time Communications 2020-02-02 12:45:00 +0100 2020-02-02 13:05:00 +0100 00:20:00:00 20200202T124500 20200202T130500 00:20:00:00 WebRTC isn't just for (video) conference calls <p>WebRTC is showing up in many places: security cameras, babymonitors, games streaming, autonomous cars etc I'll describe the advantages of WebRTC in these devices but also the challenges of non-mainstream usage.

To manage this complexity, architects, system software designers, and application developers need design and programming technologies to be flexible, accurate, efficient, and productive. Recently, our team has started to explore the mapping of GnuRadio to various heterogeneous SoCs in order to understand how programming technologies can support this goal of making this SDR framework performance portable. Using our software stack, we are porting several SDR applications to GPUs from NVIDIA, AMD, and ARM, and to NVIDIA Xavier SoCs, Qualcomm Snapdragon, and Xilinx Zynq devices. Our current approach uses a directive-based programming model and a new intelligent runtime scheduler to port and execute the workflows. We are evaluating several open programming models to enable performance portability; initially, they include directive-based compilers, OpenCL, and SYCL. All of these approaches will generate tasks that are then queued and scheduled by our open-source intelligent runtime scheduler, which is a critical component of our approach. Initial performance results appear promising; however, more automation will further broad deployment. Also, we have developed a host of tools to examine and profile SDR workflows and modules. Specifically, these analysis tools enable automated characterization of the behavioral and computational features of GNU Radio blocks and workflows. The static tools in GR-tools help developers to create ontologies and queries to classify GR modules based on custom scenarios. The dynamic toolset provides automated profiling capabilities of GR workflows and presents detailed statistics on how components in a given software defined radio application perform. GR-tools also produces a graph-based representation of the analyzed data and provides powerful visualization options to filter and display the information obtained from the static and dynamic tools. Our software is available as open-source software and will be made available to the community.</p> PUBLIC CONFIRMED Free Software Radio https:/fosdem.org/2020/schedule/event/fsr_striving_for_performance_portability/ AW1.120 Jeffrey Vetter PUBLISH 9790@FOSDEM20@pentabarf.org 9790 web3 web3 Web3 - the Internet of Freedom, Value, and Trust On exiting the system and reclaiming control of our digital and physical lives en en_US Lightning Talks 2020-02-01 13:00:00 +0100 2020-02-01 13:15:00 +0100 00:15:00:00 20200201T130000 20200201T131500 00:15:00:00 Web3 - the Internet of Freedom, Value, and Trust- On exiting the system and reclaiming control of our digital and physical lives <p>For as long as human society has existed, humans have been unable to trust each other.

It is a fact that Docker has found wide spread of use during the past years, mostly because of it being very easy to use , economic w.r.t resources used, fast and easy to deploy when compared with a full blown virtual machine. More and more servers are being operated as Docker hosts on which micro-services run in containers. From a security point of view, two aspects of it arise in the context of this talk and the inherent time-limitations it has. Firstly, the aspect of the already quite talked-through question, “is it secure ?”.Secondly the less analyzed aspect of incident analysis and the changes introduced with respect to known methods and evidence.In this presentation we will briefly outline some security considerations about Docker and the average user and then we will try to examine how Docker introduces changes to the workflow related to incident analysis and forensics in its environment.</p> PUBLIC CONFIRMED Security https:/fosdem.org/2020/schedule/event/security_docker_security_considerations_incident_analysis/ UA2.114 (Baudoux) John Lionis PUBLISH 10328@FOSDEM20@pentabarf.org 10328 dip_dat_browser dip_dat_browser DAT protocol in the browser: Progress and Challenges en en_US Decentralized Internet and Privacy 2020-02-02 13:00:00 +0100 2020-02-02 13:30:00 +0100 00:30:00:00 20200202T130000 20200202T133000 00:30:00:00 DAT protocol in the browser: Progress and Challenges <p>Dweb protocols, like DAT and IPFS, promise significant benefits over the standard client-server protocols for web content.

Part of the page_pool evolution involves adding the recycling support in the kernel's SKB stack and leverage the increased performance attributes of the API.</p> PUBLIC CONFIRMED Software Defined Networking https:/fosdem.org/2020/schedule/event/xdp_and_page_pool_api/ H.1308 (Rolin) Ilias Apalodimas Lorenzo Bianconi PUBLISH 10100@FOSDEM20@pentabarf.org 10100 riscv_bootflow riscv_bootflow RISC-V Boot flow: What's next ? en en_US RISC-V 2020-02-01 13:10:00 +0100 2020-02-01 13:30:00 +0100 00:20:00:00 20200201T131000 20200201T133000 00:20:00:00 RISC-V Boot flow: What's next ? <p>RISC-V boot flow has come a long way since in recent times by leveraging the various opensource boot loaders/firmware projects. This also helped in achieving a well-supported and standard boot flow for RISC-V. As a result, developers can use the same boot loaders to boot Linux on RISC-V as they do in other architectures. Currently, U-Boot is used as the last stage boot loader and OpenSBI as the machine mode run time service provider, but there's more work to be done. A few of such future works includes U-boot SPL support, UEFI boot in RISC-V Linux and booting protocol improvements. This talk will focus on some of these ongoing works which are necessary to declare that RISC-V is truly ready for world domination.</p> PUBLIC CONFIRMED RISC-V https:/fosdem.org/2020/schedule/event/riscv_bootflow/ K.3.401 Atish Patra PUBLISH 10209@FOSDEM20@pentabarf.org 10209 histograms histograms Secret History of Prometheus Histograms en en_US Monitoring and Observability 2020-02-02 13:10:00 +0100 2020-02-02 13:35:00 +0100 00:25:00:00 20200202T131000 20200202T133500 00:25:00:00 Secret History of Prometheus Histograms <p>Representing distributions in a metrics-based monitoring system is both important and hard.

Initiated by Mozilla, now under the umbrella of Bytecode Alliance, WASI has the potential to revolutionise the way we think about the "build once, run anywhere" in a truly secure manner. But could WASI also lend itself to a task of running any code within a network of distributed, untrusted nodes such as BOINC or Golem Network, and ensuring that the results received are indeed correct? The short answer is yes, if determinism of computations could be enforced which opens many ways at verifying the results. Enforcing determinism is a rather difficult thing to achieve in other platforms such as JVM etc., now possible thanks to Wasm and WASI.

The idea is based on moving the core computational logic and storage to distant locations that are closer to the entities they interact with (e.g. users or sensors). The benefits come from improving network latencies, increasing user experience with the provided service, and lowering the transfers to the central locations. Edge clouds bring the flexibility and proven workflows of cloud computing to the edge.</p> <p>OpenNebula is an open source framework to build private and hybrid clouds based on KVM, LXD, and/or VMware vCenter. While the main domain is the corporate private on-premises cloud, it comes with simple and extensible tooling ("oneprovision") for automated deployment of edge clouds. When provided with a deployment descriptor, it allocates the physical hosts on the public bare-metal cloud provider, configures all necessary services (e.g. install libvirt/KVM or LXD), and enables them for use in OpenNebula. The process is as simple as running a command-line tool and the cloud administrator gets a fully usable configured edge cluster in a few minutes.</p> <p>As part of a usability validation exercise, we successfully deployed public gaming servers from scratch to running services on 17 different locations worldwide in just 25 minutes: https://opennebula.org/opennebula-a-lightning-fast-video-gaming-edge-use-case-2 .</p> <p>This talk introduces the OpenNebula "edge" concept and shows the current state, capabilities, and limitations of edge cloud deployment tooling.

Incrementality, namely, the ability to efficiently compute the output for increasing inputs, or to request longer outputs, is often a property of the implementation rather than an explicit feature of a mode.</p> <p>A doubly-extendable cryptographic keyed (or deck) function is a new kind of object that makes incrementality an integral part of its definition. Writing modes for various applications, such as authenticated encryption of a network channel or disk encryption with a wide block cipher, on top of a deck function turns out to be a simple exercise and leads to less error-prone implementations than on top of a block cipher. We illustrate this with the session-supporting authenticated encryption modes SANE and SANSE. (Sessions naturally protect a continuous flow of messages or a client-server dialog.)</p> <p>While a deck function can be constructed from existing primitives, like a block cipher, we show two more natural ways of making a deck function in practice.</p> <ul> <li><p>The first one is based on the well-known permutation-based duplex construction, of which a nice instantiation is the <a href="https://strobe.sourceforge.io/">Strobe protocol framework</a>. Strobe was showcased in <a href="https://www.discocrypto.com/">Noise+Strobe=Disco</a> as an advantageous replacement to all kinds of primitives in the <a href="https://noiseprotocol.org/">Noise protocol framework</a>, resulting in <a href="https://permutationbasedcrypto.org/2018/slides/David_Wong.pdf">much simpler specifications and a lighter implementation</a>. Xoodyak, our candidate to the NIST Lightweight Cryptography competition, is another example.</p></li> <li><p>The second one is based on the recent Farfalle construction, which relies on the parallel application of a permutation. Farfalle's inherent parallelism yields deck functions that are at the same time simple and efficient on a wide range of platforms. In particular, we point out the nice performance of Kravatte and Xoofff, two deck functions based on the Keccak-p and the Xoodoo permutation, respectively. It is worth noting that Kravatte and Xoofff are much faster than AES-128 in software, and at least competitive with and often faster than AES-128 using dedicated AES instructions <a href="https://keccak.team/sw_performance.html">on the more recent Intel and AMD processors</a>!</p></li> </ul> PUBLIC CONFIRMED Security https:/fosdem.org/2020/schedule/event/security_incrementality_and_deck_functions/ UA2.114 (Baudoux) Gilles Van Assche PUBLISH 10440@FOSDEM20@pentabarf.org 10440 dip_tor_dev_intro dip_tor_dev_intro An Introduction to the Tor Ecosystem for Developers en en_US Decentralized Internet and Privacy 2020-02-02 13:30:00 +0100 2020-02-02 14:00:00 +0100 00:30:00:00 20200202T133000 20200202T140000 00:30:00:00 An Introduction to the Tor Ecosystem for Developers <p>Tor is a free and open-source software anonymization system that allows people around the world to use the internet safely. The Tor network itself is operated by various volunteering individuals and organizations around the globe, and the network carries around 200 Gbit/s of traffic and helps somewhere between 2,000,000 and 8,000,000 users every day. The Tor ecosystem is much larger than the anonymity system that Tor provides itself: The Tor Project, the non-profit behind the anonymity system, also develops and maintains a web browser based on Mozilla Firefox. The organization also does monitoring of the network, work on emerging anti-censorship technology, work with translators, and downstream distributions that do packaging in free software operating system distributions.</p> <p>In this presentation, we will have a look at what it takes to develop and maintain an anonymity system like Tor and the various other components in the Tor ecosystem. We will look at what The Tor Project has been up to lately, primarily with a focus on core Tor itself. However, we will also have a look at some of our recent developments with anti-censorship technology.

The most general model of future vehicular transportation is that of artificially intelligent, connected, autonomous vehicles (CAVs) [1].</p> <p>In this talk, we present a representative open-source application for CAVs operating as a collaborative swarm and communicating via GNU Radio. The application, called ERA [2], incorporates local sensing, creation of occupancy grid maps, vehicle-to-vehicle (V2V) communication of grid maps between neighboring vehicles using GNU Radio-based dedicated short-range communication (DSRC), and map fusion to create a joint higher-accuracy grid map [3]. Specifically, each vehicle in ERA uses its onboard sensors to generate local occupancy grid maps, which it communicates to other nearby vehicles using DSRC. When a vehicle receives occupancy maps from nearby cars, it merges the received ones with the locally-generated occupancy maps, expanding the scope and increasing the accuracy of this vehicle's perception. The DSRC transceiver adopted in ERA is an open-source GNU Radio implementation of the IEEE 802.11p standard by Bastian Bloessl [4]; while perception and map creation is implemented using ROS (Robot Operating System) [5]. We created an appropriate software interface between GNU Radio and ROS which enables proper execution and interaction of both frameworks.</p> <p>In addition to presenting a deep dive into ERA's code, we will also show performance analysis results of ERA (including its GNU Radio components) and discuss potential acceleration opportunities for performance and efficiency improvement -- including optimizations of Viterbi decoding and complex exponential through hardware acceleration. We believe that ERA can help to fill the gap between the fast-growing CAV R&amp;D domain and GNU Radio, specifically when it comes to the wireless communication aspect of future vehicles.</p> <p>[1] A.

In this session, I would like to take you to an alternative world - a world where programming languages are not parsed, a world where languages can be downloaded from the Internet and plugged easily into your IDE. A world where you have the power to customize the languages that you use. You’ll see that projectional editing in JetBrains MPS gives you incredible freedom in how you express your thoughts. It allows you to choose notations that best fit the task at hand. Your code can be edited as text, tables, diagrams, a form, or a combination of those. This is especially useful for Domain-specific languages and we’ll see real-life examples from domains such as the insurance industry, embedded software development, bioinformatics, enterprise systems and legislation. We’ll also discuss the downsides and integration challenges that projectional editors face. My goal is that you’ll leave this session inspired, enriched and motivated to try something new.</p> PUBLIC CONFIRMED Free Tools and Editors https:/fosdem.org/2020/schedule/event/projectional_editing_and_its_implications/ UD2.119 Václav Pech PUBLISH 9357@FOSDEM20@pentabarf.org 9357 perconamongodb perconamongodb Percona Backup for MongoDB: Status and Plans Open Source solution for consistent backups of multi-shard MongoDB en en_US Backup and Recovery 2020-02-01 13:40:00 +0100 2020-02-01 13:55:00 +0100 00:15:00:00 20200201T134000 20200201T135500 00:15:00:00 Percona Backup for MongoDB: Status and Plans- Open Source solution for consistent backups of multi-shard MongoDB <p>A brief overview of the current state of backup tool, architecture, existing features, and the roadmap.</p> PUBLIC CONFIRMED Backup and Recovery https:/fosdem.org/2020/schedule/event/perconamongodb/ UD2.119 Mykola Marzhan PUBLISH 9851@FOSDEM20@pentabarf.org 9851 pictor_radio_telescope pictor_radio_telescope PICTOR: A free-to-use open source radio telescope en en_US Lightning Talks 2020-02-02 13:40:00 +0100 2020-02-02 13:55:00 +0100 00:15:00:00 20200202T134000 20200202T135500 00:15:00:00 PICTOR: A free-to-use open source radio telescope <p>PICTOR, located in Athens, Greece, consists of a 1.5-meter parabolic antenna that allows anyone to make continuous and spectral (i.e. hydrogen line) drift-scan observations of the radio sky in the 1300~1700 MHz regime for free.

However, existing solutions suffer from well-known shortcomings in terms of soundness, performance and usability.</p> <p>We present <em>SaBRe</em>, a novel load-time framework for selective binary rewriting. SaBRe rewrites specific constructs of interest — mainly system calls and function prologues — when the program is loaded into memory. This enables users to intercept those constructs at runtime via a modular architecture allowing custom plugins to be linked with SaBRe using a simple and flexible API. We also discuss the theoretical underpinnings of disassembling and rewriting, including conditions for coverage, accuracy, and correctness; and how they affect SaBRe.</p> <p>We developed two backends for SaBRe — one for x86_64 and one for RISC-V — which were in turn used to implement two open-source plugins: a fast system call tracer and a fault injector. Our evaluation shows that SaBRe imposes little performance overhead, between 0.2% and 4.3% on average. In addition to explaining the architecture of SaBRe and demonstrating its performance, we also show on a concrete example how easy creating a new plugin for SaBRe is.</p> <p>SaBRe is a free open-source software released under the GPLv3 license and originally developed as part of the Software Reliabilty Group at Imperial College London.</p> PUBLIC CONFIRMED Miscellaneous https:/fosdem.org/2020/schedule/event/sabre/ K.1.105 (La Fontaine) Paul-Antoine Arras PUBLISH 9237@FOSDEM20@pentabarf.org 9237 open_source_won open_source_won AMENDMENT Open Source Won, but Software Freedom Hasn't Yet A Guide & Commiseration Session for FOSS activists en en_US Freedom 2020-02-02 14:00:00 +0100 2020-02-02 14:50:00 +0100 00:50:00:00 20200202T140000 20200202T145000 00:50:00:00 AMENDMENT Open Source Won, but Software Freedom Hasn't Yet- A Guide & Commiseration Session for FOSS activists <p>Karen and Bradley, building on the substantial feedback from last year's keynote, follow up their 2019 FOSDEM keynote with real-world suggestions, ideas, and discussion about how we, as software freedom activists, can live in a world with so much proprietary software.

The vertically integrated Cloud now is the predominant operational paradigm and is threatening to undermine software freedom. To many all seems lost, but the world keeps changing and decentralized compute is making a comeback. Containers and Kubernetes are already having a deep impact on the Linux operating system (OS) that goes well beyond DevOps and cloud-native applications. The concepts of application-centric packaging, process isolation through Linux containers, and immutable infrastructure are shaking up the core traditions of today's GNU/Linux operating systems. These concepts are also challenging the assumptions and approaches derived from the past 40+ years of work that originated with UNIX. The Linux distribution as we know it is coming to an end, and is being replaced by a new concept of containerized, multi-instance, multi-user applications, which can be deployed in scale-out environments as well as for widely distributed compute scenarios.

While graph algorithms and their complexity is textbook material, efficient implementation of such algorithms is still a major challenge due to a number of reasons. First, the irregular and unstructured nature of graphs leads to a massive amount of random data access, which makes it difficult to use typical caching and parallelization techniques. Second, to optimize their code, developers need to be aware of the nuances of the underlying hardware which, at the very least consists of multiple CPU cores but often also incorporates heterogeneous components such as GPUs or even FPGAs. During the last decade, a number of graph programming models (such as Google's Pregel) have been proposed but most of these focused defining high-level abstractions for distributed execution environments and introduced a significant runtime overhead.</p> <p>A potential approach for defining efficient graph processing algorithms is to exploit the well-known duality of graphs and sparse adjacency matrices, using matrix operations to capture algorithms. Surprisingly, only a few recent research prototypes have used this model with little consensus on the set of necessary building blocks. The GraphBLAS initiative (launched in 2013) aims to define a standard to capture graph algorithms in the language of linear algebra - following the footsteps of the BLAS standard which, starting four decades ago, revolutionized scientific computing by defining constructs on dense matrices.</p> <p>In this talk, I give an overview of the GraphBLAS standard and its key components. First, I illustrate how matrix operations on various semirings correspond to the steps in graph algorithms. I then use these operations to present fundamental graph algorithms such as breadth-first search, shortest paths, and the clustering coefficient. Finally, I demonstrate the scalability of the GraphBLAS-based algorithms with the LDBC Graphalytics benchmark. The presented implementations are available open-source as part of LAGraph, a library built on top of GraphBLAS to demonstrate how to design efficient algorithms in linear algebra.</p> PUBLIC CONFIRMED HPC, Big Data, and Data Science https:/fosdem.org/2020/schedule/event/graphblas/ UB5.132 Gabor Szarnyas PUBLISH 10031@FOSDEM20@pentabarf.org 10031 python2020_celery python2020_celery Follow Your Celery Tasks en en_US Python 2020-02-01 14:00:00 +0100 2020-02-01 14:25:00 +0100 00:25:00:00 20200201T140000 20200201T142500 00:25:00:00 Follow Your Celery Tasks <p>All Python developer who want to run asynchronous tasks should know Celery.

SRv6 leverages the IPv6 dataplane to provide overlay networking, traffic engineering, load balancing, network policy and service chaining.</p> <p>In this talk, we present an SRv6-based solution for k8s networking. We will show how SRv6 is used for pod-to-pod communication, k8s services and service function chaining (SFC), and how SRv6 solves several k8s networking challenges. We will also show the integration of our solution in Contiv-VPP.

The funny thing is: every engineer needs to re-read reference designs! Even though there are tens of thousands of designs with new components documented and available on Github. The reason: it is almost impossible to find a relevant project. The solution? Instead of using Github search, which only retrieves files by filename, our approach creates a local database that takes the search results from Github, and then parses the used components inside the PCB designs to index them. That way, you can easily search a component and get the most relevant designs as a reference.</p> <p>This talk will give an overview of the software that was created, discusses the difficulties that were overcome and the potential for improvement in future work.</p> <p>We have currently indexed 8,000 KiCad-projects on GitHub containing 37,000 electronic components as a proof-of-concept.

However, web mining can be incredibly useful to social sciences since it enables researchers to tap into a formidable source of information about society.</p> <p>But researchers may not have the possibility to invest copious amount of times into learning web technologies in and out. They usually rely on engineers to collect data from the web. The object of this talk is to explain how Sciences Po's <a href="https://medialab.sciencespo.fr/en">médialab</a> designed &amp; developed tools to empower researchers and enable them to perform web mining tasks to answer their research questions. Here is an example of issues we will tackle during this talk:</p> <ul> <li>How a social sciences laboratory life can be a very fruitful context for tool R&amp;D regarding webmining</li> <li>How to create performant &amp; effective webmining tools that anyone can use (multithreading, parallelism, JS execution, complex spiders etc.)</li> <li>How to re-localize data collection: researchers should be able to conduct their own collections without being dependent on external servers or resources</li> <li>How to teach researchers the necessary skills: HTML, the DOM, CSS selection etc.</li> </ul> <p>Examples will be taken mainly from the <a href="https://github.com/medialab/minet">minet</a> CLI tool and the <a href="https://medialab.github.io/artoo/">artoo.js</a> bookmarklet.</p> <h2>Speaker</h2> <p><a href="https://github.com/Yomguithereal">Guillaume Plique</a> is a research engineer working for SciencesPo's <a href="https://medialab.sciencespo.fr/en">médialab</a>.

Its aim is to provide tamper evident logging, i.e., to adequately protect log records of an information system against tampering and to provide a sensor indicating attack attempts. The secure logging service achieves this by authentically encrypting each log record with an individual cryptographic key used only once and protects integrity of the whole log archive by a cipher{based message authentication code. Each attempt to tamper with either an individual log record or the log archive itself will be immediately detected during log archive verification. Therefore, an attacker can no longer tamper with log records without being detected which greatly enhances the use of log archives in forensic investigations.</p> PUBLIC CONFIRMED Security https:/fosdem.org/2020/schedule/event/security_secure_logging_with_syslog_ng/ UA2.114 (Baudoux) Stephan Marwedel PUBLISH 10217@FOSDEM20@pentabarf.org 10217 om_spleeter om_spleeter Spleeter by Deezer Open-Sourcing a Machine-Learning Music Source Separation Software en en_US Open Media 2020-02-02 14:30:00 +0100 2020-02-02 14:55:00 +0100 00:25:00:00 20200202T143000 20200202T145500 00:25:00:00 Spleeter by Deezer- Open-Sourcing a Machine-Learning Music Source Separation Software <p>Source separation, stem separation, de-mixing are all different ways of referring to the same problem of recovering the mono-instruments tracks that were mixed together to produce a music file.

The Mesa 3D project makes OpenGL rendering possible using only the Linux Framebuffer with GLFBDev or EGL: mesa-demos and yagears programs will be shown. We will then cover graphics libraries (GLUT, SDL, EFL, GTK, Qt) that allow to integrate high level applications running directly on top of the Linux Framebuffer with no compositor.

While this approach provides a lot of flexibility, building software from source remains a huge barrier for users accustomed to simple, fast binary package mangers. Most package managers and container registries label binaries with a high-level architecture family name, e.g., x86_64 or ppc64le, but there is no standard way to label binaries for specific microarchitectures (haswell, skylake, power9, zen2, etc.).</p> <p>We’ll present a new project called “archspec” that aims to bridge this gap. Archspec provides a standard set of human-understandable labels for many popular microarchitectures. It models compatibility relationships between microarchitectures, and it aggregates information on ISA extensions, compiler support, and compiler flags needed to optimize these machines. Finally, it provides a standard set of names for both microarchitectures and ISA features. These features allow container tools and package managers to detect, build, and use optimized binaries.</p> <p>Archspec grew out of the Spack package manager, but it is intended for widespread use by other build, packaging, and containerization tools. We will describe how it has been used in practice so far, how it has simplified writing generic packages, and our plans to get contributions from vendors and the broader community.</p> PUBLIC CONFIRMED HPC, Big Data, and Data Science https:/fosdem.org/2020/schedule/event/archspec/ UB5.132 Todd Gamblin PUBLISH 10468@FOSDEM20@pentabarf.org 10468 online_open_document_editing_new_possibilities online_open_document_editing_new_possibilities Online Open Document Editing New Possibilities en en_US Open Document Editors 2020-02-01 15:00:00 +0100 2020-02-01 15:25:00 +0100 00:25:00:00 20200201T150000 20200201T152500 00:25:00:00 Online Open Document Editing New Possibilities <p>Open Document editing is, as many things in life, more and more an online action.

By combining the right set of hardware resources (cores, accelerators, chip interconnects and memory technology) along with an adequate software stack (operating system and programming interface), heterogeneous chips have become an effective high-performance and low-power computing alternative.</p> <p>However, heterogeneous architectures come with new challenges. Fundamentally, the complexity derived from the design's heterogeneous nature challenges the effective scheduling of tasks (processes), a scenario that becomes even more critical when real-time execution deadlines must be met. This is particularly important in the context of GNU Radio, given that its underlying scheduler is completely unaware of chip heterogeneity today. Early stage prototyping and evaluation of GNU Radio scheduling policies in heterogeneous platforms becomes a valuable asset in the design process of a future GNU Radio scheduler.</p> <p>In this talk, we present a new open-source simulator for fast prototyping of task scheduling policies, called STOMP (Scheduling Techniques Optimization in heterogeneous Multi-Processors) [1]. It is written in Python and implemented as a queue-based discrete-event simulator with a convenient interface that allows users and researchers to "plug in" new scheduling policies in a simple manner. We also present a systematic approach to task scheduling in heterogeneous platforms through the evaluation of a set of progressively more "intelligent" scheduling policies using STOMP. We rely on synthetic kernels representative of a GNU Radio application [2], including functions like Viterbi decoding and fast Fourier transform (FFT) that have to be scheduled across general-purpose cores, GPUs or hardware accelerators to meet the application's real-time deadlines.

This ensures that the execution of each build tool is deterministic and not subject to system-wide state. Unfortunately, creating these sandboxes is costly, and every millisecond added to the runtime of each action has a large impact on total build time. Just consider that Bazel focuses on large-ish builds with thousands of actions in them: each little inefficiency quickly multiplies and can result in significant slowdowns, and developers always want faster build times. In this talk, I'll explain how Bazel implements sandboxing and I will cover a FUSE file system I've been developing, sandboxfs, to optimize this process.

OpenStreetMap is the best source of information for cycle routes and these relations can easily be downloaded using the OverpassAPI.</p> <p>In this talk I will present an Open Source tool to download GPX tracks of cycle routes, and a website for people to download the generated GPX files. I will discuss some of the nuances of how cycle routes are stored as relations and what processing needs to be performed in order to create a continuous route. In addition, I will speak about how the tool can be used to identify inconsistencies in OpenStreetMap data.</p> PUBLIC CONFIRMED Geospatial https:/fosdem.org/2020/schedule/event/creating_gpx_tracks_from_cycle_routes_in_openstreetmap/ AW1.126 Henry Miskin PUBLISH 9380@FOSDEM20@pentabarf.org 9380 graph_graffiti graph_graffiti Graffiti A historical, distributed graph engine en en_US Graph Systems and Algorithms 2020-02-01 15:25:00 +0100 2020-02-01 15:45:00 +0100 00:20:00:00 20200201T152500 20200201T154500 00:20:00:00 Graffiti- A historical, distributed graph engine <p>Graffiti is the graph engine of Skydive - an open source networking analysis tool.

However the commoditization of compute resources and the introduction of new scientific fields such as life sciences to high performance computing has caused a shift in this paradigm. Today, an increasing number of biological software is made accessible through web portals. This improved ease of use has led towards a democratization of access to computational resources Users of those fields don’t have the same computational knowledge as traditional HPC users from physics or chemistry and additionally require different kinds of workloads and applications that don’t fit traditional non-interactive batch scheduling resource management systems. Additionally, cloud computing is becoming more and more relevant and various efforts to lift HPC into the Cloud were started.</p> <p>We manage the HPC infrastructure for 3 life science and 2 particle physics institutions at the Vienna Bio Center (VBC). For the new HPC system that was procured at the end of 2018, we decided to go with an on-prem cloud framework based on OpenStack to accommodate the various emerging workflows and programs. OpenStack is not a finished product and requires considerable amount of engineering. It took us around 2 years of testing and engineering to feel confident in deploying the new HPC infrastructure on top of OpenStack. Since summer 2019 we have our 200 node production SLURM cluster running on top of VMs in OpenStack.</p> <p>In this talk we want to share our experiences from our endeavor into HPC on OpenStack. We want to briefly discuss the reasoning behind HPC in the cloud and specifically OpenStack. Often times these kind of projects either completely fade away in case of failure or get published in a high-level white paper that is only useful as marketing material. We want to share our honest experience from both implementer and operator perspective. We discuss how we use 3 environments to test updates and configuration changes. We will also explain our approach to automation and infrastructure as code all the way from the underlying infrastructure to the SLURM payload and how we keep our sanity using development procedures around pull requests and code reviews. We will also share some stories from the trenches, such as why you still learn new things about OpenStack after 1000 deploys or discover that a simple config change can destroy performance. This talk will contain information that you won’t find in success stories or white papers but is hopefully very helpful or anyone who considers deploying HPC on OpenStack.</p> PUBLIC CONFIRMED HPC, Big Data, and Data Science https:/fosdem.org/2020/schedule/event/hpc_openstack/ UB5.132 Ümit Seren PUBLISH 10085@FOSDEM20@pentabarf.org 10085 new_features_vue new_features_vue New features of Vue 3.0 en en_US JavaScript 2020-02-02 15:30:00 +0100 2020-02-02 15:55:00 +0100 00:25:00:00 20200202T153000 20200202T155500 00:25:00:00 New features of Vue 3.0 <p>Vue 3.0 is scheduled to be released in Q1 2020.

Somewhat improbably, the format was picked up across the iron curtain in the German Democratic Republic, where it experienced its age of greatest popularity.

To measure the impact of such changes, going beyond the classic W3C notion of page load time, a number of Web performance metrics has been proposed (such as SpeedIndex, Above-The-Fold and variants). At the same time, there is still a limited amount of understanding on how these metrics correlate with the user perception (e.g., such as user ratings, user-perceived page load time, etc.).

(Examples includes Drakvuf, PANDA, PyREBox, icebox, etc...). If we want to make the most out of VMI in the future, we need to build the libraries that will unify this ecosystem and let the developers focus on what matters: building quality VMI apps.</p> <p>This is where libmicrovmi comes into play. It aims to solve this problem, by providing a core, foundation library, written in Rust, to be cross-platform, hypervisor-agnostic and emulator-agnostic, on top of which higher-level libraries and apps can rebase.</p> <p>Rust makes a lot of sense for VMI for 2 main reasons:</p> <ul> <li>Rust is safe: considering that we are processing untrusted input from virtual machines, we cannot allow any crash or exploitation in the introspection agent. Also one of our use case is OS hardening, which needs an excellent level of trust</li> <li>Rust is fast: processing an event requires to pause the VCPU. The longer the pause, the more delayed the guest execution will be, and when scaling to thousands of events per second this can dramatically influence how many breakpoints you are willing to put, especially on production systems. Speed matters.</li> </ul> <p>Therefore Rust is the de facto choice for VMI apps in the future, and we are building it today, by providing libmicrovmi, a new foundation for VMI.</p> <p>Libmicrovmi has drivers for:</p> <ul> <li>Xen</li> <li>KVM</li> <li>Hyper-V (in progress)</li> </ul> PUBLIC CONFIRMED Rust https:/fosdem.org/2020/schedule/event/rust_vm_introspection/ K.3.401 Mathieu Tarral PUBLISH 10412@FOSDEM20@pentabarf.org 10412 deployment_to_hardware deployment_to_hardware Deployment to hardware A multi pipeline challenge en en_US Continuous Integration and Continuous Deployment 2020-02-02 15:40:00 +0100 2020-02-02 16:20:00 +0100 00:40:00:00 20200202T154000 20200202T162000 00:40:00:00 Deployment to hardware- A multi pipeline challenge <p>Our project takes a fun, road-following app which leverages a basic neural network and deploys it to real hardware with an OStree update system.

However, as user count and resource demand increase, these setups become more complex. While these frameworks typically provide good support for cloud based deployments in container orchestrations, it is often preferable to deploy them on existing compute infrastructure that provides access to both software packages and the data to be analysed. The deployment on HPC batch systems specifically brings challenges on how to handle authentication, user identities, and job submissions.</p> <p>The architecture of these applications can be considered as following the master -- minion paradigm in most cases. One central component manages user access and acts as a gateway. It launches one or multiple per-user instances of a compute component, that provides the actual user environment.</p> <p>We want to demonstrate how we provide applications like Galaxy, Jupyterhub, and RStudio to scientists of the Vienna Biocenter.

This is mostly because operating system components have to be individually specialized and developed for each target application and target platform.</p> <p>In this talk we give an update on the Unikraft open source project. Unikraft is a toolkit for creating specialized unikernels and it aims to remove the need for time-consuming, expert work. In the past two years, the community has put a lot of effort into supporting OS functionality, drivers, and platforms, porting libraries, and providing tools to ease porting of existing applications. We will give an overview of all the exciting achievements and conclude with an outlook of recent project directions: binary compatibility (Linux ABI), support for a wide range of compiled and interpreted languages (e.g., web assembly, Go, Python, Ruby, etc.), enhanced safety features, and the ability to seamlessly produce images ready to run as extremely lean VMs, containers, or directly on bare metal. The aim is that Unikraft will represent a step forward towards wider adoption of unikernels beyond the research community.</p> PUBLIC CONFIRMED Microkernels and Component-based OS https:/fosdem.org/2020/schedule/event/uk_unicraft/ K.4.601 Simon Kuenzer PUBLISH 10288@FOSDEM20@pentabarf.org 10288 online_wrestling_web_copypaste_to_usability online_wrestling_web_copypaste_to_usability Online: wrestling web Copy/Paste to usability Defeating the API and implementation disasters in copy/paste en en_US Open Document Editors 2020-02-01 16:00:00 +0100 2020-02-01 16:25:00 +0100 00:25:00:00 20200201T160000 20200201T162500 00:25:00:00 Online: wrestling web Copy/Paste to usability- Defeating the API and implementation disasters in copy/paste <p>Overcoming the synchronous web copy/paste API's limitations in real browsers is extremely non-trivial.

The simulation of quantum circuits is usually achieved by gate matrix product, such as in Qiskit and ProjectQ. Thanks to the Lindblad master equation solver, QuTiP is developing a simulator that simulates quantum circuits at the level of the real quantum evolution happening in your quantum device. This framework offers pulse-level control and a flexible way of noise simulation. Upon it, we are going to define different back-ends for different physics systems such as Cavity QED, Ion trap or Superconducting system.

These are commonly used to transport media streams from remotes to the content provider, or the content provider to distribution. They allow, for example, streams from a pro basketball game to be transported over public Internet from stadium to network NOC without error; or as another example, packages of ethnic TV channels, to be moved from continent to continent. Players include DVEO, which uses the proprietary Dozer protocol for which the speaker holds the patent; WOWZA uses a customized SRT which is based on open source, and a few more. They all work on the principle of shooting off a bunch of udp packets from one IP to another, setting up a buffer, and then using an automatic re-request mechanism to request re-sends of lost or corrupted udp packets. RIST was designed with the participation of several vendors to bring some of the features normally found in proprietary error correction protocols into the free and open source world. It may even become a "lingua franca" between vendors. VLC, upipe and gstreamer can already reassemble and play back RIST transported streams. We will talk about a new open source project that provides an easy to use lib for rist and we'll discuss two pre-packaged images we've made available for AWS, Azure, VMWare and KVM.

One challenge faced by this approach is how to distribute metadata among the MDSs. Unlike data storage and it's associated I/O throughput, which can be scaled linearly with the number of storage devices, file-system metadata is a fairly complex entity to scale due to it's hierarchical nature. In hindsight, a pure hashing based metadata distribution strategy seems like a perfect fit. But, this is not exactly the case. What are the pitfalls then? Too many inter-MDS hops (due to POSIX traversal semantics), loss of hierarchical locality degrades file-system performance, and as a result, this is not beneficial for a workload whose directory hierarchy tree grows in depth rather than breadth. CephFS's metadata balancer takes a different approach by partitioning metadata sub-trees across MDSs thereby preserving good locality benefits. Although efficient, this involves a lot of back and forth migrations of sub-trees and the locality benefits are sometimes trumped by sub-optimal distributions.</p> <p>In this talk, we present a new metadata distribution strategy employed in CephFS - Ephemeral Pinning. This strategy combines the benefits of hashing and naive sub-tree partitioning by intelligently pinning sub-trees to MDSs so as to obtain a balanced distribution as the workload metadata grows by depth and breadth. A consistent hashing based load balancer helps in maintaining an optimal distribution during addition or failure of MDSs.</p> PUBLIC CONFIRMED Software Defined Storage https:/fosdem.org/2020/schedule/event/ephemeral_pinning_a_dynamic_metadata_management_strategy_for_cephfs/ H.1308 (Rolin) Sidharth Anupkrishnan PUBLISH 10666@FOSDEM20@pentabarf.org 10666 kubernetes_gitops kubernetes_gitops AMENDMENT How secure is your build/server? a story of packages and trust en en_US Continuous Integration and Continuous Deployment 2020-02-02 16:25:00 +0100 2020-02-02 17:00:00 +0100 00:35:00:00 20200202T162500 20200202T170000 00:35:00:00 AMENDMENT How secure is your build/server?- a story of packages and trust <p>We have learned that we need to trust others, but as our parents used to say - don’t trust strangers.

However, many scientific experiments benefit from the flexibility, stability and reconfigurability of digital signal processing even when handling radiofrequency signals. In this presentation, we address two demonstrations of this concept. First, readily available SDR hardware is used to replace general purpose laboratory instruments (spectrum analyzer, lock in amplifier) for characterizing radiofrequency processing acoustic transducers (filters, resonators). The benefit of SDR lies in communication bandwidth: while general purpose instrument communication protocols (GPIB, VXI11 over Ethernet) require hundreds of milliseconds or seconds to transfer data, SDR platforms stream at high bandwidth I/Q coefficients collected on the fly on a ZeroMQ socket by the (GNU/Octave) processing software. We demonstrate a 10000 fold bandwidth gain when converting a general purpose instrument experiment to a SDR approach. Another approach is to address high bandwidth radiofrequency oscilloscopes as radiofrequency source for time of flight measurement. The gr-oscilloscope GNU Radio source demonstrates how to communicate between GNU Radio and laboratory grade equipment, here oscilloscopes, for processing discontinuous data streams using GNU Radio.</p> PUBLIC CONFIRMED Free Software Radio https:/fosdem.org/2020/schedule/event/fsr_software_defined_radio_based_scientific_instrumentation/ AW1.120 Jean-Michel Friedt PUBLISH 9515@FOSDEM20@pentabarf.org 9515 ema_yocto_extra_tools ema_yocto_extra_tools How Yocto extra tools help industrial project Yocto is not (only) bitbake en en_US Embedded, Mobile and Automotive 2020-02-01 16:30:00 +0100 2020-02-01 17:20:00 +0100 00:50:00:00 20200201T163000 20200201T172000 00:50:00:00 How Yocto extra tools help industrial project- Yocto is not (only) bitbake <p>Yocto is the most famous "build system" for embedded Linux.

A variety of products, such as ECMWF reanalyses and archived forecasts, are additionally available to users via the MARS archive and the Copernicus data portal. Transferring, storing and locally modifying large volumes of such data prior to integration currently presents a significant challenge to users. The key aim for ECMWF within the H2020 HiDALGO project is to migrate some of these tasks to the cloud, thereby facilitating fast and seamless application integration by enabling precise and efficient data delivery to the end-user. The required cloud infrastructure development will also feed into ECMWF's contribution to the European Weather Cloud pilot which is a collaborative cloud development project between ECMWF and EUMETSAT.</p> <p>ECMWF and its HiDALGO partners aim to implement a set of services that enable the simulation of complex global challenges which require massive high performance computing resources alongside state-of-the-art data analytics and visualization.</p> <p>ECMWF's role in the project will be to enable seamless integration of two pilot applications with its meteorological data and services delivered via ECMWF's Cloud and orchestrated by bespoke HiDALGO workflows. The demonstrated workflows show the increased value of weather forecasts, but also derived forecasts for air quality as provided by the Copernicus Atmospheric Monitoring Service (CAMS).</p> <p>The HiDALGO use-case workflows are comprised of four main components: pre-processing, numerical simulation, post-processing and visualization. The core simulations are ideally suited to running in a dedicated HPC environment, due to their large computational demands, coupled with the heavy communication overhead between parallel processes. However, the pre-/post-processing and visualisation tasks generally do not demand more than a few cores to compute and do not require message passing between instances, hence they are good candidates to run in a cloud environment. Enabling, managing and orchestrating the integration of both HPC and cloud environments to improve overall performance is the key goal of HiDALGO.</p> <p>This talk will give a general overview of HiDALGO project and its main aims and objectives. It will present the two test pilot applications which will be used for integration, and an overview of the general workflows and services within HiDALGO. In particular, it will focus on how ECMWF's cloud data and services will couple with the test pilot applications to improve overall workflow performance and enable access to new data for the pilot users.</p> <p>This work is supported by the HiDALGO project and has been partly funded by the European Commission's ICT activity of the H2020 Programme under grant agreement number: 824115.</p> PUBLIC CONFIRMED HPC, Big Data, and Data Science https:/fosdem.org/2020/schedule/event/ecmwf/ UB5.132 John Hanley PUBLISH 10064@FOSDEM20@pentabarf.org 10064 building_confidence_in_security building_confidence_in_security Building Confidence & Overcoming Insecurity The ultimate software supply chain self-help guide en en_US Dependency Management 2020-02-01 16:30:00 +0100 2020-02-01 17:00:00 +0100 00:30:00:00 20200201T163000 20200201T170000 00:30:00:00 Building Confidence & Overcoming Insecurity- The ultimate software supply chain self-help guide PUBLIC CONFIRMED Dependency Management https:/fosdem.org/2020/schedule/event/building_confidence_in_security/ UD2.119 Jeff McAffer PUBLISH 10117@FOSDEM20@pentabarf.org 10117 web_of_twins web_of_twins Web of Twins From IoT to Immersive worlds and beyond... en en_US JavaScript 2020-02-02 16:30:00 +0100 2020-02-02 16:55:00 +0100 00:25:00:00 20200202T163000 20200202T165500 00:25:00:00 Web of Twins- From IoT to Immersive worlds and beyond... <p>Overview of Web of Things concept, Mozilla WebThings IoT platform demonstrated using A-Frame 3D framework for building virtual reality experiences.</p> PUBLIC CONFIRMED JavaScript https:/fosdem.org/2020/schedule/event/web_of_twins/ H.1302 (Depage) Philippe Coval PUBLISH 10211@FOSDEM20@pentabarf.org 10211 monitoring_large_scale_uni_network monitoring_large_scale_uni_network Monitoring of a Large-Scale University Network: Lessons Learned and Future Directions en en_US Monitoring and Observability 2020-02-02 16:30:00 +0100 2020-02-02 16:55:00 +0100 00:25:00:00 20200202T163000 20200202T165500 00:25:00:00 Monitoring of a Large-Scale University Network: Lessons Learned and Future Directions <p>The complexity of network monitoring strongly depends on the size of the network under observation. Challenges in monitoring large-scale networks arise not only from dealing with a large volume of traffic, but also from keeping track of all traffic sources, destinations, and who-talks-to-whom communications. Analyzing this information allows to uncover new behaviors that would have not been visible by merely observing common metrics such as bytes and packets. The drawback is that extra pressure is put on the monitoring system as well and on the downstream data- and timeseries-stores.</p> <p>This talk presents a case study based on the monitoring of a large-scale university network. Challenges faced, findings, and lessons learned will be examined. It will be shown how to make sense of the input data to properly manage and reduce its scale as early as possible in the monitoring system. The discussion will also highlight the advantages and limitations of the opensource software components of the monitoring system. In particular, the opensource network monitoring tool ntopng and the timeseries-store InfluxDB will be considered. It will be shown what happens when ntopng and InfluxDB are pushed to their limits and beyond, and what it can be done to ensure their smooth operation. Relevant findings, behaviors uncovered in the network traffic, and future directions will conclude the talk. Intended audience is technical and managerial individuals who are familiar with network monitoring.</p> PUBLIC CONFIRMED Monitoring and Observability https:/fosdem.org/2020/schedule/event/monitoring_large_scale_uni_network/ UD2.120 (Chavanne) Simone Mainardi Tobias Appel PUBLISH 10284@FOSDEM20@pentabarf.org 10284 infratesting infratesting Infrastructure testing, it's a real thing! en en_US Infra Management 2020-02-01 16:30:00 +0100 2020-02-01 17:25:00 +0100 00:55:00:00 20200201T163000 20200201T172500 00:55:00:00 Infrastructure testing, it's a real thing! <p>Software developers have been testing their code for years.

As a result, multiple small experiments are developed and outputs are gathered as best as possible to be presented in a scientific paper. However, science is not only about sharing results but also sharing methods. How can we make our results reproducible when we developed multiple, usually undocumented analyses? What do we do if the program is only applicable to our computer directory architecture? This is always possible to take time to rewrite, re-arrange and document analyses at the time we want/have to share them. Here, I will take the exemple of a "collaboration fest" where we dissected R scripts of a researcher in ecology. We started a reproducible, documented and open-source R-package along with its website, automatically built using continuous integration: <a href="https://cesco-lab.github.io/Vigie-Chiro_scripts/">https://cesco-lab.github.io/Vigie-Chiro_scripts/</a>.<br/> However, can we think, earlier in the process, a better way to use our small programming time slots by adopting a method that will save time in our future? In this aim, I will present a documentation-first method using little time while writing analyses, but saving a lot when the time has come to share your work.</p> PUBLIC CONFIRMED Open Research Tools and Technologies https:/fosdem.org/2020/schedule/event/open_research_shareable_workflow/ AW1.126 Sébastien Rochette PUBLISH 10342@FOSDEM20@pentabarf.org 10342 integrate_collabora_online_with_web_applications integrate_collabora_online_with_web_applications Integrate Collabora Online with web applications en en_US Open Document Editors 2020-02-01 16:30:00 +0100 2020-02-01 16:55:00 +0100 00:25:00:00 20200201T163000 20200201T165500 00:25:00:00 Integrate Collabora Online with web applications <p>Come and hear how to integrate Collabora Online – a powerful online office suite based on LibreOffice code – with web applications.

At the same time, the hype surrounding computing and Internet of Things Gateways has led to an increase in network appliance devices. Our target was to create a less-insecure virtual network appliance using TrenchBoot, Trusted Platform Module 2.0 and AMD SKINIT Dynamic Root of Trust for Measurement to establish a Xen hypervisor with a meta-virtualized pfSense firewall. We are going to present it with an update of the status of support of TrenchBoot for AMD processors. This appliance is supported by are supported by apu2, a reliable low-SWaP x86 device from Swiss OEM PC Engines. It can be used as a Single Office / Home Office firewall or an industrial edge device and has mostly open-source hardware, coreboot firmware, mPCIe extensibility and an extended support lifecycle for the embedded Central Processing Unit and motherboard. In this talk, we will show how to create a system, which enables a significant portion of computations to the edge devices while maintaining security. Using a simple, well-known platform, we will conduct a secure boot using the Static Root of Trust for Measurement with coreboot, move to the Dynamic Root of Trust for Measurement by SKINIT in TrenchBoot and use all of this to provide a complete chain of trust for the Xen hypervisor, a virtual firewall appliance isolated by an input–output memory management unit (IOMMU) from the physical network interface controller (NIC) devices.

Today, there are also many companies with businesses built around open source software. At first glance, it may seem impossible to build an open and authentic community for a company-based open source project when you need to balance the needs of the company with those of the community. In this talk, you will find that there are actually a lot similarities between contributors in company-based and traditional open source projects. Additionally, it is possible to build a thriving community by satisfying the intrinsic motivation of contributors and providing opportunities for community members to have a voice in how the community (or even the business) is run.

This has resulted in a fast-growing community that has been developing various database and algorithmic innovations in this area, many of which will be gathering together in this conference. We joined this field as computer architecture researchers and are currently building a complete hardware-software design, called DECADES, that aims to accelerate the execution of these algorithms.</p> <p>From a computer architecture point of view, applications involving dense matrix operations such as neural networks have garnered much attention for their acceleration through specialized hardware such as GPUs and TPUs, while graph applications remain difficult to improve even with modern specialized accelerator designs. The reason for this is the characteristic pointer-based data structures of graph applications and the resulting irregular memory accesses performed by many of these workloads. Such irregular memory accesses result in memory latency bottlenecks that dominate the total execution time. In this talk, as part of the DECADES infrastructure, we present an elegant hardware-software codesign solution, named FAST-LLAMAs, to overcome these memory-bottlenecks, and thus, accelerate graph and sparse applications in an energy efficient way.</p> PUBLIC CONFIRMED Graph Systems and Algorithms https:/fosdem.org/2020/schedule/event/graph_hardware_software_co_design/ AW1.121 Margaret Martonosi Aninda Manocha PUBLISH 10742@FOSDEM20@pentabarf.org 10742 fosdem_infrastructure fosdem_infrastructure FOSDEM infrastructure review en en_US Lightning Talks 2020-02-02 16:40:00 +0100 2020-02-02 16:55:00 +0100 00:15:00:00 20200202T164000 20200202T165500 00:15:00:00 FOSDEM infrastructure review <p>Informational and fun.</p> PUBLIC CONFIRMED Lightning Talks https:/fosdem.org/2020/schedule/event/fosdem_infrastructure/ H.2215 (Ferrer) Richard Hartmann PUBLISH 10762@FOSDEM20@pentabarf.org 10762 geochallenge geochallenge Wallonia GeoChallenge geodata, ideas and challenges en en_US Geospatial 2020-02-02 16:40:00 +0100 2020-02-02 17:00:00 +0100 00:20:00:00 20200202T164000 20200202T170000 00:20:00:00 Wallonia GeoChallenge - geodata, ideas and challenges <p>During the first months of 2020, the Geoportail of Wallonia, and some partners will organise a public event called « The GeoChallenge ».</p> <p>In a few words, the idea is to ask participants to solve public services or citizens expectations by using Wallonia’s geographic information and ressources.</p> <p>More than a hackathon, the event will last a few weeks with the idea to create results that translate into concrete benefits.</p> <p>The first call for proposals will be launched in february and will last until the end of 16th of march.</p> PUBLIC CONFIRMED Geospatial https:/fosdem.org/2020/schedule/event/geochallenge/ AW1.126 Emmanuel Jauquet PUBLISH 9597@FOSDEM20@pentabarf.org 9597 retro_reviving_minitel retro_reviving_minitel Reviving Minitel How web technologies make it easy to emulate Minitel en en_US Retrocomputing 2020-02-01 16:45:00 +0100 2020-02-01 17:15:00 +0100 00:30:00:00 20200201T164500 20200201T171500 00:30:00:00 Reviving Minitel- How web technologies make it easy to emulate Minitel <p>Using web technologies, one can easily emulate the Minitel ecosystem, not only the iconic french terminal but also its servers.

At NVIDIA, we use containers extensively in our GPU clusters for both HPC and deep learning applications. We love containers for how they simplify software packaging and enable reproducibility without sacrificing performance. Docker is a popular tool for running application containers on Linux, and while it is possible to enable container workflows for users by granting them access to the docker daemon, the security impact needs to be carefully considered, especially in a shared environment. Relying on docker for the container runtime also requires a large amount of complicated boilerplate code to start multi-node jobs using the Message Passing Interface (MPI) for communication. In this presentation, we will introduce a new lightweight container runtime inspired from LXC and an associated plugin for the Slurm Workload Manager. Together, these two open-source projects enable a more secure architecture for our clusters, while also enabling a smoother user experience with containers on multi-node clusters.</p> PUBLIC CONFIRMED Containers https:/fosdem.org/2020/schedule/event/containers_hpc_unprivileged/ UD2.208 (Decroly) Felix Abecassis Jonathan Calmels PUBLISH 10729@FOSDEM20@pentabarf.org 10729 npes npes Helpful NullPointerExceptions - The little thing that became a JEP en en_US Free Java 2020-02-01 16:50:00 +0100 2020-02-01 17:15:00 +0100 00:25:00:00 20200201T165000 20200201T171500 00:25:00:00 Helpful NullPointerExceptions - The little thing that became a JEP <p>One of the most prevalent - if not the most prevalent - exception type in Java is the NullPointerException. While Java set out to overcome the possibilities to do the mistakes one can do when programming in languages like C/C++ by not exposing pointers in the Java language, the misleading term 'pointer' sneaked into this exception. To this day, NullPointerExceptions thrown by the runtime system didn't contain messages. All you had was a callstack and a line number. But in typical expressions and statements there are several dereferences where an NPE can occur in one line.</p> <p>We - some engineers in the SAP team - thought this could be helped by a little enhancement. The new NPE message gives precise information about the location and tries to explain what was going on when a null reference was encountered. However, due to its prominent nature, it eventually became a JEP.</p> <p>In my talk I'll demonstrate the improvements that come with this enhancement. I will lift the hood a little and provide a glance at its implementation details.

While programming support for basic general-purpose accelerators such as GPUs has become quite mature in many ways, general heterogeneous SoCs in particular can feature a much broader range of accelerators in their efforts to minimize power consumption while maximizing performance. Many SoCs, though, are designed with accelerators tailored for the domain -- such as signal processing -- in which they’ll be used: Domain-Specific SoCs. As SoC platforms become ever-more heterogeneous, we think that application developers shouldn’t need to waste time reading datasheets or APIs for SoC-specific kernel extensions just to take full advantage of their hardware. With this in mind, in this talk we will discuss strategies we are using to automate mapping of LLVM-compatible languages to heterogeneous platforms with no intervention (not even #pragmas) from the programmer.</p> <p>To this end, we present our prototype of a software stack that seeks to address both of these needs. To meet the first need, we developed an LLVM-based hybrid compile/run-time toolchain to extract the semantic operations being performed in a given application. With these semantic operations extracted, we can link in additional libraries that enable dispatch of certain kernels (such as a Fast Fourier Transform) to accelerators on the SoC without user intervention. To evaluate the functionality of this toolchain, we developed a runtime system built on top of QEMU+Linux that includes scheduling and task dispatch capabilities targeting hypothetical SoC configurations. This enables behavioral modeling of these accelerators before silicon (or even FPGA) implementations are available. The focus here will be on the LLVM-mapping aspects, but a brief overview of our SoC simulation environment will be presented as well.</p> PUBLIC CONFIRMED LLVM https:/fosdem.org/2020/schedule/event/llvm_aut_prog_het_soc/ K.4.201 Joshua Mack Nirmal Kumbhare PUBLISH 10034@FOSDEM20@pentabarf.org 10034 clc_weblate_localize_your_project_the_developer_way clc_weblate_localize_your_project_the_developer_way AMENDMENT Weblate!

As analysing the traces for possible branches and loops is hard and stressful work, we created our own framework for automatic reverse engineering. Our framework allows to capture and analyse MMIO traces, fuzz the BLOB under test and finally generates readable code in a high level language, like C, for easy analysing.</p> <p>During this talk, we will discuss the legal side, the motivation behind reverse engineering, and the benefit for the Open Source community.

Much effort has been spent on this problem for modern single-language ecosystems, but many of these ecosystems rely on natively compiled libraries, and dependency mangers often fail at managing the additional complexities that native libraries entail. Further, dependency resolution has traditionally been modeled as a SAT problem, where the package manager should find <em>any</em> workable solution to satisfy package constraints. However, <em>any</em> solution may not be good enough. Users want the most tested, most optimized, or most secure configuration, and this is a SAT problem coupled with complex optimization.</p> <p>Spack is a package/dependency manager rapidly gaining popularity in High Performance Computing (HPC) that aims to address many of the complexities of native, multi-language, cross-platform dependency management. Spack has recently been reworked to use Answer Set Programming (ASP), a declarative logic programming paradigm that also provides sophisticated facilities for optimization. This talk will cover how we’ve been able to model the compiler toolchain, ISA, build options, ABI, and other constraints on native libraries. We’ll also talk about how ASP has been a useful tool for finding <em>optimized</em> dependency configurations. This work can be used to improve dependency resolvers in general — so that they can prefer more secure or tested configurations instead of simply selecting the most recent workable versions.</p> PUBLIC CONFIRMED Dependency Management https:/fosdem.org/2020/schedule/event/dependency_solving_not_just_sat/ UD2.119 Todd Gamblin PUBLISH 10606@FOSDEM20@pentabarf.org 10606 ema_ptxdist ema_ptxdist The State of PTXdist en en_US Embedded, Mobile and Automotive 2020-02-01 17:30:00 +0100 2020-02-01 17:55:00 +0100 00:25:00:00 20200201T173000 20200201T175500 00:25:00:00 The State of PTXdist <p>PTXdist has been around as a build tool for embedded systems for more than 16 years now, but many new features were added in the recent time.

The actual project description (made of work packages, tasks, deliverable items, ...) has lots of redundancies and cross-references that makes its coherency as frail as a house of cards. For example, if the duration of a task is changed most probably you'll need to update the effort in person-months of the task and of the including work package; you must update the start date of depending tasks and the deliver date of any deliverable items; most probably also the WP efforts and length need update too; not to mention the need of updating all the summary tables (summary of efforts, deliverable, ..) and the GANTT too. Any small changes is likely to start a ripple of updates and the probability of forgetting something and getting an incoherent project description is large. Given the harsh competition in project funding, if your project is incoherent the probability of getting funded is nil.</p> <p>One day I got sick of this state of affair and I wrote my own project generator: 10k lines of Ada code that reads a non-redundant project description from a simple-format text file and produces a set of files ready to be imported in the proposal, GANNT chart included.

However, not everyone in those enterprises has the skills to participate in OpenSource communities, feels ready to contribute something or to create and run a vibrant OpenSource community. I observed that there are two distinct groups of people - one with OSS background, ability and willingness to operate in that domain and those that will likely only use OSS without any likeliness to contribute or participate. Let's change that and build a bridge between those two groups while generating value for the enterprise making it more likely to receive support for this activity. InnerSource, the application of OpenSource principles and practices within the enterprise, can be this bridge. You'll learn about creating opportunities for people who haven't been exposed to OpenSource collaboration to learn about the OpenSource ways of collaboration in a safe environment within their organization by creating shared projects internally that follow OpenSource practices and principles. You'll also learn about how organizations can profit from cross-team/silo collaboration and knowledge exchange. Also, the acquisition of very valuable skills by their employees that can facilitate the successful transition of those internal projects into OpenSource and creation of vibrant communities around them. This approach is successfully used by many enterprises, and I'm part of a community who has built and is building OpenSource-d training material for this.

We will briefly describe at a high-level the key parallel abstraction of hierarchical dataflow graphs used in HPVM, and then focus on on how HPVM is integrated on top of LLVM. A second part of the talk will briefly describe how we are extending HPVM to enable greater energy efficiency and performance by taking advantage of <em>approximation</em> opportunities in application domains such as machine learning and image processing. To conclude, I will briefly discuss how HPVM might be added as a dialect in MLIR so that other MLIR dialects and MLIR-based compilers can use HPVM for code generation to diverse heterogeneous hardware targets, including GPUs, FPGAs, and custom accelerators.</p> PUBLIC CONFIRMED LLVM https:/fosdem.org/2020/schedule/event/llvm_hpvm/ K.4.201 Vikram Adve PUBLISH 10400@FOSDEM20@pentabarf.org 10400 containers_bpf_tracing containers_bpf_tracing Inspektor Gadget and traceloop Tracing containers syscalls using BPF en en_US Containers 2020-02-01 17:45:00 +0100 2020-02-01 18:05:00 +0100 00:20:00:00 20200201T174500 20200201T180500 00:20:00:00 Inspektor Gadget and traceloop- Tracing containers syscalls using BPF <p>I will present Inspektor Gadget and traceloop, a tracing tool to trace system calls in cgroups or in containers using BPF and overwritable ring buffers.</p> PUBLIC CONFIRMED Containers https:/fosdem.org/2020/schedule/event/containers_bpf_tracing/ UD2.208 (Decroly) Alban Crequy PUBLISH 9024@FOSDEM20@pentabarf.org 9024 closing_fosdem closing_fosdem Closing FOSDEM 2020 en en_US Keynotes 2020-02-02 17:50:00 +0100 2020-02-02 18:15:00 +0100 00:25:00:00 20200202T175000 20200202T181500 00:25:00:00 Closing FOSDEM 2020 <p>Some closing words.

Whether we have got it all right is left as a follow-up exercise for attendees.</p> PUBLIC CONFIRMED Free Java https:/fosdem.org/2020/schedule/event/secure_jvm/ H.1302 (Depage) Andrew Dinn PUBLISH 10777@FOSDEM20@pentabarf.org 10777 quantum_computer_brands_connecting_apples_and_oranges quantum_computer_brands_connecting_apples_and_oranges Quantum computer brands: connecting apples and oranges en en_US Quantum Computing 2020-02-01 17:50:00 +0100 2020-02-01 18:25:00 +0100 00:35:00:00 20200201T175000 20200201T182500 00:35:00:00 Quantum computer brands: connecting apples and oranges PUBLIC CONFIRMED Quantum Computing https:/fosdem.org/2020/schedule/event/quantum_computer_brands_connecting_apples_and_oranges/ UA2.118 (Henriot) Petar Korponaić PUBLISH 9861@FOSDEM20@pentabarf.org 9861 openelectronicslab openelectronicslab Designing Hardware, Journey from Novice to Not Bad Reflections from the OpenElectronicsLab en en_US Open Source Computer Aided Modeling and Design 2020-02-01 17:55:00 +0100 2020-02-01 18:15:00 +0100 00:20:00:00 20200201T175500 20200201T181500 00:20:00:00 Designing Hardware, Journey from Novice to Not Bad- Reflections from the OpenElectronicsLab <p>The three main contributors to the OpenElectronicsLab projects started out as relative novices.

This model fits naturally within a streaming architecture, where new events can be inserted directly into the graph upon arrival from a data source, being compared to related entities or historical state. However, the vast majority of graph processing systems only consider traditional graph analysis on static data, with some outliers supporting batched updating and temporal analysis across graph snapshots. This talk will cover recent work defining a temporal graph model which can be updated via event streams and investigating the challenges of distribution and graph maintenance. Some notable challenges within this include partitioning a graph built from a stream, with the additional complexity of managing trade-offs between structural locality (proximity to neighbours) and temporal locality (proximity to an entities history). Synchronising graph state across the cluster and handling out-of-order updates, without a central ground truth limiting scalability. Managing memory constraints and performing analysis in parallel with ongoing update ingestion. To address these challenges, we introduce Raphtory, a system which maintains temporal graphs over a distributed set of partitions, ingesting and processing parallel updates in near real-time. Raphtory's core components consist of Graph Routers and Graph Partition Managers. Graph Routers attach to a given input stream and convert raw data into graph updates, forwarding this to the Graph Partition Manager handling the affected entity. Graph Partition Managers contain a partition of the overall graph, inserting updates into the histories of affected entities at the correct chronological position. This removes the need for centralised synchronisation, as commands may be executed in any given arrival order whilst resulting in the same history. To deal with memory constraints, Partition Managers both compress older history and set an absolute threshold for memory usage. If this threshold is met a cut-off point is established, requiring all updates prior to this time to be transferred to offline storage. Once established and ingesting the selected input, analysis on the graph is permitted via Analysis Managers. These connect to the cluster, broadcasting requests to all Partition Managers who execute the algorithm. Analysis may be completed on the live graph (most up-to-date version), any point back through its history or as a temporal query over a range of time. Additionally, multiple Analysis Managers may operate concurrently on the graph with previously unseen algorithms compiled at run-time, thus allowing modification of ongoing analysis without re-ingesting the data. Raphtory is an ongoing project, but is open source and available for use now. Raphtory is fully containerised for ease of installation and deployment and much work has gone into making it simple for users to ingest their own data sources, create custom routers and perform their desired analysis. The proposed talk will discuss the benefits of viewing data as a temporal graph, the current version of Raphtory and how someone could get involved with the project. We shall also touch on several areas of possible expansion at the end for discussion with those interested.</p> PUBLIC CONFIRMED Graph Systems and Algorithms https:/fosdem.org/2020/schedule/event/graph_raphtory/ AW1.121 Ben Steer PUBLISH 10586@FOSDEM20@pentabarf.org 10586 retro_mainframe_on_laptop retro_mainframe_on_laptop Running a mainframe on your laptop (for fun and profit) en en_US Retrocomputing 2020-02-01 17:55:00 +0100 2020-02-01 18:25:00 +0100 00:30:00:00 20200201T175500 20200201T182500 00:30:00:00 Running a mainframe on your laptop (for fun and profit) <p>Yes, this talk is about running your own mainframe on your own hardware.

However many users still interact with these systems through proprietary models served on specialized cloud hardware. In this talk we discuss co-design efforts between researchers in natural language processing and computer architecture to develop an open-source software/hardware system for natural language translation and understanding across languages. With this system, users can access state-of-the-art models for translation, speech, and classification, and also run these models efficiently on edge device open-hardware designs.</p> <p>Our work combines two open-source development efforts, OpenNMT and FlexNLP. The OpenNMT project is a multi-year collaborative project for creating an ecosystem for neural machine translation and neural sequence learning. Started in December 2016 by the Harvard NLP group and SYSTRAN, the project has since been used in many research and industry applications. The project includes highly configurable model architectures and training procedures, efficient model serving capabilities for use in real world applications, and extensions to tasks such as text generation, tagging, summarization, image to text, and speech to text. FlexNLP is an open-source fully retargetable hardware accelerator targeted for natural language processing. Its hardware design is targeted to key NLP computational functions such as attention mechanisms and layer normalization that are often overlooked by today’s CNN or RNN hardware accelerators. FlexNLP’s rich instruction set architecture and microarchitecture enable a diverse set of computations and operations that are paramount for end-to-end inference on state-of-the-art attention-based NLP models. Together they provide an open pipeline for both model training and edge device deployment.</p> PUBLIC CONFIRMED Coding for Language Communities https:/fosdem.org/2020/schedule/event/clc_open_edge_hardware_and_software_for_language_translation_and_understanding/ AW1.120 Alexander Rush Thierry Tambe PUBLISH 10467@FOSDEM20@pentabarf.org 10467 firmware_culisfu firmware_culisfu Capsule Update & LVFS: Improving system firmware updates Improving reliability and security by simplifying distribution of firmware updates en en_US Open Source Firmware, BMC and Bootloader 2020-02-01 18:00:00 +0100 2020-02-01 18:25:00 +0100 00:25:00:00 20200201T180000 20200201T182500 00:25:00:00 Capsule Update & LVFS: Improving system firmware updates- Improving reliability and security by simplifying distribution of firmware updates <p>As the rich capabilities of platforms increase, so does their complexity. As hypervisors and operating systems harden their attack surfaces, malware has been moving deeper into the platform. For example, a modern laptop may have over 15 updatable firmware elements, each with low-level access to a specific hardware domain. From the early days of proprietary BIOS in the 1980’s and 1990’s, to the world of standards in the 2000’s, to the post-PC world of the last few years, the nature of firmware has changed. In order to provide security guarantees for platform firmware, the servicing model of the platform takes center stage.</p> <p>This session discusses the evolution of platform servicing using examples based on device firmware, non-host/system on a chip (SOC) firmware, and implementation of the Unified Extensible Firmware Interface (UEFI). A modern servicing model features elements for component-based update, resiliency in case unexpected conditions, a more seamless user experience, lowering the friction of update integration, and telemetry for a view into platform health and firmware inventory.</p> <p>This talk will discuss current trends in standards such as UEFI and associated EDK II firmware, and how the Linux Vendor Firmware System (LVFS) used these components as part of a holistic, open source approach to seamless firmware updates.</p> PUBLIC CONFIRMED Open Source Firmware, BMC and Bootloader https:/fosdem.org/2020/schedule/event/firmware_culisfu/ K.4.601 Brian Richardson PUBLISH 10483@FOSDEM20@pentabarf.org 10483 lightning_talk_session lightning_talk_session Lightning talk session en en_US Open Document Editors 2020-02-01 18:00:00 +0100 2020-02-01 18:55:00 +0100 00:55:00:00 20200201T180000 20200201T185500 00:55:00:00 Lightning talk session PUBLIC CONFIRMED Open Document Editors https:/fosdem.org/2020/schedule/event/lightning_talk_session/ UB4.136 Thorsten Behrens PUBLISH 10562@FOSDEM20@pentabarf.org 10562 ema_lognplot ema_lognplot lognplot - logging and plotting data from micro's Tracing data on a modern laptop en en_US Embedded, Mobile and Automotive 2020-02-01 18:00:00 +0100 2020-02-01 18:25:00 +0100 00:25:00:00 20200201T180000 20200201T182500 00:25:00:00 lognplot - logging and plotting data from micro's- Tracing data on a modern laptop <p>Embedded systems are hard to debug.

As a result, research software and the time spent developing it have become invisible scholarly contributions. This lack of visibility reduces the incentives that are necessary to produce and share high quality software that are essential for the progress of science. The Journal of Open Source Software (JOSS) is an open source, open access journal primarily designed to make it easier for those individuals authoring research software to gain career credit for their work by publishing short software papers. Software papers are a recognized mechanism for authors of research software to create a citable ‘entity’ which can easily be cited in journals and as such directly impact a researcher’s career via established metrics such as the h-index. JOSS is unique in that it only accepts very short (~ 1-2 pages) papers, with short summaries and links to the software repository. In that sense, the software papers are not the focus of the review. Instead, we ask reviewers to conduct a thorough review of the associated software (which must be open source) ensuring that it is well documented, straightforward to install and functions as expected. In this talk I will describe the origin and impact that JOSS has had on research open source and also touch upon issues such as sustainability and credit.</p> PUBLIC CONFIRMED Open Research Tools and Technologies https:/fosdem.org/2020/schedule/event/open_research_joss/ AW1.126 Karthik Ram PUBLISH 10693@FOSDEM20@pentabarf.org 10693 ada_rad ada_rad On Rapid Application Development in Ada en en_US Ada 2020-02-01 18:00:00 +0100 2020-02-01 18:20:00 +0100 00:20:00:00 20200201T180000 20200201T182000 00:20:00:00 On Rapid Application Development in Ada <p>In the Ada world we typically write mission critical software that just has to work, but in a way one could argue that a lot more software is mission critical than is usually admitted.</p> <p>What does it take to actually perform rapid application development in any language?

We, therefore, extended the distributed graph analytics framework Gradoop for time-related graph analysis by introducing a new temporal property graph data model. Our model supports bitemporal time dimensions for vertices and edges to represent both rollback and historical information. In addition to the data model, we introduce several time-dependent operators (e.g, Snapshot, Diff and Grouping) that natively support the natural evolution of the graph. Since this is an extension of Gradoop, the temporal operators are compatible and can be combined with the already known operators to build complex analytical tasks in a declarative way. In our talk, we will give a brief overview of the Gradoop system, the temporal property graph model and how we support the time-dependent analysis of large graphs. Based on real-world use-cases, we show the expressiveness and flexibility of our temporal operators and how they can be composed to answer complex analytical questions.</p> PUBLIC CONFIRMED Graph Systems and Algorithms https:/fosdem.org/2020/schedule/event/graph_temporal_gradoop/ AW1.121 Kevin Gomez Christopher Rost PUBLISH 10297@FOSDEM20@pentabarf.org 10297 webperf_building_openspeedmonitor webperf_building_openspeedmonitor The journey of building OpenSpeedMonitor Learnings from unexpectedly finding ourselves developing a FLOSS project en en_US Web Performance 2020-02-01 18:20:00 +0100 2020-02-01 18:55:00 +0100 00:35:00:00 20200201T182000 20200201T185500 00:35:00:00 The journey of building OpenSpeedMonitor- Learnings from unexpectedly finding ourselves developing a FLOSS project <p>Keeping track caring about web performance is hard with constantly changing standards, improving browsers, frameworks and devices.

GPUs have powerful parallel processing capabilities that are adopted to accelerate the execution of applications. In a cloud environment, containers may require one or more GPUs to fulfill the resource requirement of application execution, while on the other hand exclusive GPU resource of a container usually results in underutilized resource. Therefore, how to share GPUs among containers becomes an attractive problem to cloud providers. In this presentation, we propose an approach, called vCUDA, to sharing GPU memory and computing resources among containers. vCUDA partitions physical GPUs into multiple virtual GPUs and assigns the virtual GPUs to containers as request. Elastic resource allocation and dynamic resource allocation are adopted to improve resource utilization. The experimental results show that vCUDA only causes 1.015% of overhead by average and it effectively allocates and isolates GPU resources among containers.</p> PUBLIC CONFIRMED Containers https:/fosdem.org/2020/schedule/event/containers_gpu_virtualization/ UD2.208 (Decroly) Shengbo Song PUBLISH 9233@FOSDEM20@pentabarf.org 9233 20_min_mysql_plugin 20_min_mysql_plugin 20 mins to write a MySQL Shell Plugin Extend the MySQL Shell with a plugin created from scratch en en_US MySQL, MariaDB and Friends 2020-02-01 18:40:00 +0100 2020-02-01 19:00:00 +0100 00:20:00:00 20200201T184000 20200201T190000 00:20:00:00 20 mins to write a MySQL Shell Plugin- Extend the MySQL Shell with a plugin created from scratch <p>MySQL Shell is a new client for MySQL.
