Over the past 2 years, we have designed and built multiple Blockchain applications and proof of concepts for fortune 500 companies. In this process, we have made many rookie mistakes and the experience has helped us to create a record of best practices in designing and building Blockchain applications. This knowledge has also enabled us to design Blockchain elective courses for Universities which we share with them freely so that students can learn from it.</p> <p>In this talk, I will share our Blockchain application development best practices as well as demonstrate (with code) how to leverage them with different Blockchain platforms like Ethereum, Hyperledger and R3 Corda. By the end of the talk, you should have a clear idea on what techniques have delivered good results and things that should be avoided when you plan on building a Blockchain application.</p> PUBLIC CONFIRMED Blockchain and Crypto Currencies https:/fosdem.org/2019/schedule/event/cancelled_best_practices_for_building_scalable_blockchain_applications/ H.1302 (Depage) Girish Nuli PUBLISH 7747@FOSDEM19@pentabarf.org 7747 ceph_data_services ceph_data_services AMENDMENT Data services in a hybrid cloud world with Ceph Making data as portable as your stateless microservices en en_US Storage 2019-02-03 09:00:00 +0100 2019-02-03 09:50:00 +0100 00:50:00:00 20190203T090000 20190203T095000 00:50:00:00 AMENDMENT Data services in a hybrid cloud world with Ceph- Making data as portable as your stateless microservices <p><em>PLEASE NOTE: Sage was delayed travelling and this talk has been rearranged from 13.00 on Saturday.</em></p> <p>IT organizations of the future (and present) are faced with managing infrastructure that spans multiple private data centers and multiple public clouds. Emerging tools and operational patterns like kubernetes and microservices are easing the process of deploying applications across multiple environments, but the achilles heel of such efforts remains that most applications require large quantities of state, either in databases, object stores, or file systems. Unlike stateless microservices, state is hard to move.</p> <p>Ceph is known for providing scale-out file, block, and object storage within a single data center, but it also includes a robust set of multi-cluster federation capabilities. This talk will cover how Ceph's underlying multi-site capabilities complement and enable true portability across cloud footprints--public and private--and how viewing Ceph from a multi-cloud perspective has fundamentally shifted our data services roadmap, especially for Ceph object storage.</p> PUBLIC CONFIRMED Storage https:/fosdem.org/2019/schedule/event/ceph_data_services/ H.2215 (Ferrer) Sage Weil PUBLISH 7982@FOSDEM19@pentabarf.org 7982 containers_kubic containers_kubic openSUSE Kubic for Container People Exploring the Containerised Frontiers en en_US Containers 2019-02-03 09:00:00 +0100 2019-02-03 09:30:00 +0100 00:30:00:00 20190203T090000 20190203T093000 00:30:00:00 openSUSE Kubic for Container People- Exploring the Containerised Frontiers <p>As the world moves more and more towards containerised solutions, a number of real questions start to appear. - What is the perfect platform for running containers atop? - How to use this platform as part of a flexible, scalable, highly available infrastructure fabric? - How to minimize the maintenance and administration of this platform at scale?</p> <p>All of these problems are well answered in an enterprise environment by SUSE CaaS Platform, but for developers more interested in the state of containers &amp; kubernetes upstream, new issues start to appear. With such fast moving upstreams, developers and enthusiasts need a platform that can keep up and is closely involved with those upstream developments. This platform needs to not only be able to run containers at scale, but also on single machine, all the while preserving the attributes of low maintenance so the focus can be on the containers, not the base system beneath them.</p> <p>This talk will introduce openSUSE Kubic, and explains how it addresses the above, being the perfect platform for container developers and enthusiasts. The session will mention how Kubic is based on the Tumbleweed rolling release and various upstreams including kubeadm and CRI-O. The kubeadm Kubernetes cluster boostrapping tool will be discussed in some detail and demonstrated, with some sneak peaks into how it may be extended in the future.</p> <p>Attendees should come away from this talk with everything they need to know to get starting using, developing with and contributing to openSUSE Kubic.</p> PUBLIC CONFIRMED Containers https:/fosdem.org/2019/schedule/event/containers_kubic/ UA2.114 (Baudoux) Richard Brown PUBLISH 8150@FOSDEM19@pentabarf.org 8150 rapids rapids RAPIDS Data Science on GPUs en en_US HPC, Big Data and Data Science 2019-02-03 09:00:00 +0100 2019-02-03 09:45:00 +0100 00:45:00:00 20190203T090000 20190203T094500 00:45:00:00 RAPIDS - Data Science on GPUs <p>The next big step in data science will combine the ease of use of common Python APIs, but with the power and scalability of GPU compute.

By learning from the human-oriented components of code, recent research has invented models that start to "understand" some aspects of source code. This opens the exciting possibility of using machine learning to assist developers in their everyday tasks, such as writing new code and finding bugs.</p> <p>In this talk, I will give a brief tour of our lab's recent explorations in this area.

Indeed, in its recent releases, the Linux kernel can be extended with small BPF bytecode programs whose memory and fault safety is statically verified at load time. These programs are usually written in a subset of C and compiled to the BPF bytecode. To access kernel memory they must use special functions, called helpers.</p> <p>The bcc framework provides Python, Lua, and C++ wrappers to install and interact with these programs, as well as syntactic sugar for the C subset. In particular, bcc allows developers to access kernel memory as easily as they would access the BPF stack. C programs are transparently rewritten at load time, before their compilation to BPF bytecode, to translate all dereferences of pointers to kernel memory (called external pointers) into calls to the appropriate helpers.</p> <p>In this talk, after providing the necessary background on BPF, we will discuss bcc's use of Clang to track external pointers throughout the code and rewrite their dereferences. We will describe the problems we had to overcome with code examples and detail the limitations of the current implementation. Among other things [2], bcc performs three traversals of the AST to track external pointers across BPF programs (through persistent data structures), follows external pointers through assignments, return values, and structure members, and keeps track of their indirections levels.</p> <p>1 - https://github.com/iovisor/bcc 2 - https://github.com/iovisor/bcc/blob/master/src/cc/frontends/clang/b_frontend_action.cc</p> PUBLIC CONFIRMED LLVM https:/fosdem.org/2019/schedule/event/llvm_bpf_rewriting/ K.4.201 Paul Chaignon PUBLISH 7587@FOSDEM19@pentabarf.org 7587 ml_on_code_code_review_suggestions ml_on_code_code_review_suggestions Suggesting Fixes during Code Review with ML en en_US ML on Code 2019-02-03 09:50:00 +0100 2019-02-03 10:30:00 +0100 00:40:00:00 20190203T095000 20190203T103000 00:40:00:00 Suggesting Fixes during Code Review with ML <p>Many developers hate doing code reviews.

Visibility tools that have access to packets are, in theory, able to produce metrics up to the packet-by-packet resolution, that is, the best one could hope for. Nevertheless, high-resolution metrics are particularly demanding in terms of storage and this has actually posed a practical upper-limit on the metrics resolution, that rarely offer sub-minute samplings. Fortunately, thanks to the tremendous evolution of big-data stores, it is now possible to rethink network visibility solutions for the generation and storage of high-resolution network metrics. This talk discuss the challenges behind the generation and storage of high-resolution metrics and demonstrates how opensource software ntopng, InfluxDB, and Grafana can be used together to build an effective high-resolution network visibility solution.

Nowadays, more than half of accepted papers pass artifact evaluation and share related code and data. Unfortunately, lack of a common experimental framework, common research methodology and common formats places an increasing burden on evaluators to validate a growing number of ad-hoc artifacts. Furthermore, having too many ad-hoc artifacts and Docker snapshots is almost as bad as not having any (!), since they cannot be easily reused, customized and built upon.</p> <p>While overviewing more than 100 papers during artifact evaluation at HPC conferences, we noticed that many of them use similar experimental setups, benchmarks, models, data sets, environments and platforms. This motivated us to develop Collective Knowledge (CK), an open workflow framework with a unified Python API to automate common researchers’ tasks such as detecting software and hardware dependencies, installing missing packages, downloading data sets and models, compiling and running programs, performing autotuning and co-design, crowdsourcing time-consuming experiments across computing resources provided by volunteers similar to SETI@home, reproducing results, automatically generating interactive articles, and so on: http://cKnowledge.org .</p> <p>In this talk I will introduce CK concepts and present several real world use cases from the Raspberry Pi foundation, ACM, General Motors, Amazon and Arm on collaborative benchmarking, autotuning and co-design of efficient software/hardware stacks for emerging workloads including deep learning. I will also present our latest initiative to create an open repository of reusable research components and workflows at HPC conferences.

Which deprecated functions are central to crates.io and should not be deleted? Am I breaking important clients and their dependencies with my new release? These are questions that package publishers and owners of package repositories crave for answers to. To solve this problem, we created RustPräzi: a call-based dependency network that represents a gigantic single large versioned call graph of all crates.io packages.</p> <p>In this talk, I will describe how RustPräzi is developed, the challenges we faced while compiling the entire crates.io and the future directions.

About 75% of Debian official packages do build fine, it has mainstream gcc/glibc/llvm support, go and rust ports are ongoing, it can be installed with the Debian installer and GuixSD and Arch ports are ongoing...</p> <p>Yet not so much has been happening within the Hurd itself in the past couple of years. We have notably added a PCI arbiter, which allows for both flexible and safe PCI access for end users, and some basic ACPI support is ongoing. But many exciting features could be achieved with a bit of work.</p> <p>This talk will discuss some of these promising features, to give a sort of ideas roadmap for contributions. Some have implementation sketches which just need to be polished to be more production-ready, such as httpfs, mboxfs, or writing translators in more high-level languages than C. Other features are at early stage, such as adding sound support through rump, getting complete rid of disk drivers from the kernel by moving them to userland, or also getting valgrind support.

"WHY in the world did we choose Lua for our data files again?" was an interrogation I had not so far in the past, when I was working for a big game company. "HOW did we let this Grunt file grow more than 8000 js lines?" was a more recent one. Programming languages are NOT a good fit for data files. But there may be another way... Today, I want to talk about my favorite part of lisp languages: <strong>making your own languages when you need them</strong>. By that I don't mean making a big pile of utility functions or macros for the savvy lisper to drool upon, but actually taking the time to think about a file format, may it be completely static, and make it from scratch using s-expressions.

This data is being collected, analyzed, sold and aggregated to cast profiles about us by companies across the globe.</p> <p>In the physical world, if a stranger was to follow you everywhere you go, keep a log of who you talk to and meet with, read your mails and then share all this information with others, wouldn’t you be concerned? But somehow in the digital world we do not seem to worry too much about the same scenarios.</p> <p>One of the main reasons for this is lack of awareness about how most Internet companies are making money these days. In fact, as a consequence of the business model of brokering personal data, a surveillance capitalism emerges.</p> <p>With the advent of SaaS, website and app owners usually outsource functionality like analytics, recommendations, A/B tests to be managed by third parties, with legitimate business purposes.</p> <p>While these use-cases might seem legit, the way data is collected to solve the legit use-cases are bound to harm the user’s privacy. You end up sharing sensitive user data with the companies you may have never heard of. They can not only link the webpages you visit but also have the ability to de-anonymize you by knowing your name, email, address, passport number etc.</p> <p>Once this information leaves your machine, it is out of your control. From it, a detailed profile about you is created, which is then available to a whole bunch of parties, which may or may not live to any ethical standards. With accurate enough profiles, companies and data brokers can simulate the behaviors and decision making of the world's population. They don't even need everyone's interactions because they can infer the whole population behavior from just a few examples of each cluster.</p> <p>This is why privacy is everyone’s concern so we need to raise awareness: - The general public needs to know how every move that they make in the online world is being tracked, shared and used. - Developers need to consider how their users and customers' data deserves to be treated with respect and care, not sold unknowingly to faceless companies.</p> <p>But how do you transmit this complex reality to the broader audience outside our community?

Today, there are six libraries focused on classical computing: alice, easy, kitty, lorina, mockturtle and percy. All libraries are well documented and tested. Furthermore, being header-only, the libraries can be readily used as core components in complex design automation systems, e.g., Yosys.</p> <p>In this talk, I will demonstrate how simple it is to compose these libraries to create a personalized synthesis tool capable of reading a Verilog description of a circuit, building a logic network out of it, optimizing the logic network, and then map it to lookup tables of six inputs (LUT6).</p> <p>The libraries: - The alice library is a lightweight wrapper for shell interfaces, which is the typical user interface for most design automation applications. It includes a Python interface to support scripting. - The lorina library is a parsing library for simple CAD file formats. - The kitty library is a truth table library for explicit representation and manipulation of Boolean functions. - The mockturtle library implements several logic network representations and logic optimization algorithms. - percy is an exact synthesis library with multiple engines to find optimum logic networks.</p> PUBLIC CONFIRMED CAD and Open Hardware https:/fosdem.org/2019/schedule/event/epfl_logic_synthesis/ AW1.125 Bruno Schmitt PUBLISH 8774@FOSDEM19@pentabarf.org 8774 learning_to_rank learning_to_rank Learning to Rank Explained for Dinosaurs en en_US Search 2019-02-03 11:00:00 +0100 2019-02-03 11:50:00 +0100 00:50:00:00 20190203T110000 20190203T115000 00:50:00:00 Learning to Rank - Explained for Dinosaurs <p>Internet search has evolved from its early days.

Such products might produce a core-file that is used for investigating cause of problem that produced it. First thing from which we start debug analysis is call-trace from a crash. In such traces most of the parameters are reported as optimized out due to variety of reasons. Some of parameters are really optimized out, but some of their locations could be calculated. Expert software developers are able to find what values parameters had at function entry point by using the technique that requires searching those values in disassembly of caller frame at place of that particular function call. Automation of such technique is described by DWARF 5 specifications and it is already implemented in GCC and GDB since 2011. The goal of this paper is to present ideas, implementation and problems that we encountered while we were working on this feature in LLVM. We will also show the improvement by presenting recovered parameters in some of the call-traces.

At the same time, it poses a great challenge to the systems and application engineers to continuously maintain regression tests that cover as many aspects as possible of the user experience. In this presentation, we present ReFrame, a new framework for writing regression tests for HPC systems. ReFrame is designed to abstract away the complexity of the interactions with the system and separate the logic of a regression test from the low-level details, which pertain to the system configuration and setup. Regression tests in ReFrame are simple Python classes that specify the basic parameters of the test plus any additional logic. The framework will load the test and send it down a wel-defined pipeline which will take care of its execution. All the system interaction details, such as programming environment switching, compilation, job submission, job status query, sanity checking and performance assessment, are performed by the different pipeline stages. Thanks to its high-level abstractions and modular design, ReFrame can also serve as a tool for continuous integration (CI) of scientific software, complementary to other well-known CI solutions. Finally, we present the use cases of two large HPC centers that have adopted or are now adopting ReFrame for regression testing of their computing facilities.</p> PUBLIC CONFIRMED HPC, Big Data and Data Science https:/fosdem.org/2019/schedule/event/reframe/ UA2.118 (Henriot) Victor Holanda PUBLISH 8658@FOSDEM19@pentabarf.org 8658 graph_gephi_js graph_gephi_js Gephi JS: Exploring the dystopian future of a Javascript Gephi en en_US Graph Processing 2019-02-02 11:15:00 +0100 2019-02-02 11:55:00 +0100 00:40:00:00 20190202T111500 20190202T115500 00:40:00:00 Gephi JS: Exploring the dystopian future of a Javascript Gephi <p>Gephi is a popular network analysis open source software written in Java. This talk about its future is a joint effort by the Gephi dev team and Javascript experts to explore the issues and opportunities of web technologies for large-scale network analysis and visualization.</p> <p>Gephi relies on the Swing library for the general user interface plus an OpenGL insert for network visualization. This choice made more than 10 years ago was one of the very few options available for a multiplatform software able to harness GPU power for displaying millions of nodes and edges. Despite a number of issues, the situation was considered relatively satisfying.</p> <p>However two long-term trends force the Gephi dev team to reconsider its future: computer infrastructures are moving away from true multiplatform software to web-based interfaces, and Java is moving away from user interface development to server-side computation. Most if not all UX developers agree that web technologies are better supporting modern UX design than the Java ecosystem. However the specific use of OpenGL puts Gephi is a special situation. We know from user surveys that scaling up your network is key to most users. No Gephi user has only small networks, and many of them has tried to analyze networks with hundred thousands nodes or more. This use case is far from usual in the world of web technologies. Is WebGL up to the task of visualizing such amount of objects?</p> <p>We used existing Javascript libraries to build a stack comparable to the basic features of Gephi. Graphology was used as a Javascript equivalent of Gephi's GraphStore library, and a tweaked version of Sigma JS WebGL renderer was used as display engine. We used this prototype to benchmark the performance of web technologies for rendering large graphs in OpenGL.</p> <p>In parallel we explored the possibility to keep the project in the Java world but stop relying on the JOGL library that is at risk of being less and less maintained.

This could provide more privacy and less censorship, or less privacy and more censorship, depending on how it is deployed and who gets to control the resolvers.

Mainly driven by hardware prototype iterations, it makes project time and cost hard to forecast. While software modifications can be done in a modular and non-destructive way, reworking on hardware implies production of new prototypes. Moreover, software optimizations being strongly hardware-dependent, the software development could remain idle during hardware re-prototyping. This uncertainty on time and cost makes embedded systems projects hard to fund. In the end, ambitious projects are mostly reserved to large companies. Hardware simulation and virtual prototyping contributes to solve this issue. A virtual prototype consists in a software application representing the system's hardware behavior, allowing system's software to be directly executed without the real hardware. Once available, a virtual prototype reduces embedded system time-to-market and development cost. However, virtual prototype development cost makes them inaccessible. Hardware simulation leverages models which are hard to find and which interoperability is lacking. Each company should invest and maintain its own virtual prototyping solution. That is why in Hiventive, we believe that the emergence of an open source, unified, normalized hardware and software ecosystem leveraging state-of-the-art virtual prototyping technologies and methodologies is necessary to boost and widely generalize the use of virtual prototypes. Thus, we will present our innovative open source collection of solutions to enable and empower virtual prototyping for everyone.</p> PUBLIC CONFIRMED CAD and Open Hardware https:/fosdem.org/2019/schedule/event/virtual_prototyping/ AW1.125 Guillaume Delbergue PUBLISH 7872@FOSDEM19@pentabarf.org 7872 multikuber multikuber Multilingual Kubernetes The kubernetes.io stack, how we got there, and what it took to get there en en_US Tool the Docs 2019-02-02 11:30:00 +0100 2019-02-02 11:55:00 +0100 00:25:00:00 20190202T113000 20190202T115500 00:25:00:00 Multilingual Kubernetes- The kubernetes.io stack, how we got there, and what it took to get there <p>How Kubernetes SIG Docs changed our stack, our git workflow, and the world.</p> PUBLIC CONFIRMED Tool the Docs https:/fosdem.org/2019/schedule/event/multikuber/ UD2.119 Zach Corleissen PUBLISH 8148@FOSDEM19@pentabarf.org 8148 community_guidelines community_guidelines Now what?

In October 2016, the European Parliament accepted a directive on the accessibility of websites and mobile applications provided by public sector bodies (Directive (EU) 2016/2102). New public sector websites in the EU will need to conform by 23 September 2019, all public sector websites will need to conform by 23 September 2020, and all public sector mobile apps will need to conform by 23 June 2021. The directive references standard EN 301 549, which has been updated to reflect the requirements in the Web Content Accessibility Guidelines (WCAG) 2.1. This new legal situation will create a greater demand for accessibility-related training and training resources for public sector bodies. The EU-funded project MOOCAP (MOOC Accessibility Partnership, https://moocap.gpii.eu/, September 2014 - August 2017) created 11 free online courses about various aspects of digital accessibility.

For some applications (e.g. grep, awk, cc, ...) this is very straightforward. Others are a lot harder to test, for example firewalls. Typically testing firewalls takes two to three hosts. One to send traffic, the firewall test host and one to receive traffic. This makes automated test orchestration complex and brittle. This in turn means that tests either don't get written, are difficult to write and/or suffer random failures unrelated to issues in the firewall itself.

That is, the code a scientist runs locally must be able to run identically on any computational resource. Until recently, the job of ensuring that fell to system administrators who needed to manage a complex web of tools and dependencies on those resources. However, with the introduction of HPC containers via Singularity, the ability to mobilize the compute environment has never been easier. Singularity allows anybody to run their own containers on HPC, ushering in a new era of computational mobility, validity, and reproducibility.</p> <p>Singularity is the most widely used container solution in high-performance computing (HPC). Enterprise users interested in AI, Deep Learning, compute drive analytics, and IOT are increasingly demanding HPC-like resources. Singularity has many features that make it the preferred container solution for this new type of “Enterprise Performance Computing” (EPC) workload. Instead of a layered filesystem, a Singularity container is stored in a single file. This simplifies the container management lifecycle and facilitates features such as image signing and encryption to produce trusted containers. At runtime, Singularity blurs the lines between the container and the host system allowing users to read and write persistent data and leverage hardware like GPUs and Infiniband with ease. The Singularity security model is also unique among container solutions. Users build containers on resources they control or using a service like the Sylabs Remote Build Service. Then they move their containers to a production environment where they may or may not have administrative access and the Linux kernel enforces privileges as it does with any other application. These features make Singularity a simple, secure container solution perfect for HPC and EPC workloads.</p> PUBLIC CONFIRMED HPC, Big Data and Data Science https:/fosdem.org/2019/schedule/event/containers_hpc_singularity/ UA2.118 (Henriot) Eduardo Arango PUBLISH 8455@FOSDEM19@pentabarf.org 8455 chips4makers chips4makers Lesson learned from Retro-uC and search for ideal HDL for open source silicon en en_US CAD and Open Hardware 2019-02-03 11:45:00 +0100 2019-02-03 11:55:00 +0100 00:10:00:00 20190203T114500 20190203T115500 00:10:00:00 Lesson learned from Retro-uC and search for ideal HDL for open source silicon <p>The <a href="https://www.crowdsupply.com/chips4makers/retro-uc">Retro-uC</a> was a crowdfunding campaign for an open source silicon project.

We argue that this is due to the design of the API of cryptographic libraries, which requires knowledge about cryptographic mechanisms and how to correctly embed them into specific use cases. However, most developers do not possess the required expert knowledge in this area. The lack of expertise in one specialist area is not a bad thing in itself, as developers excel in other areas. Therefore, we argue that the design of APIs of cryptographic libraries have to be substantially improved. We show you how easy it is to make mistakes during the integration of cryptographic mechanisms. We discuss how a few simple and well-known programming techniques can be utilized to make cryptographic APIs more usable for application developers and introduce a free software library which integrates cryptographic functions using an easier API in order to avoid common pitfalls.</p> <p>The improvement of the correct integration of established cryptographic tools is a quite simple but essential step to achieve a higher level of security in general.</p> PUBLIC CONFIRMED Security https:/fosdem.org/2019/schedule/event/crypto_pitfalls/ UD2.218A Maximilian Blochberger PUBLISH 8538@FOSDEM19@pentabarf.org 8538 media_gstreamer_rust media_gstreamer_rust Fearless Multimedia Programming using GStreamer & Rust en en_US Open Media 2019-02-02 12:00:00 +0100 2019-02-02 12:25:00 +0100 00:25:00:00 20190202T120000 20190202T122500 00:25:00:00 Fearless Multimedia Programming- using GStreamer & Rust <p>GStreamer is a popular framework of choice for multimedia programming in the Linux world, especially for embedded.

It scales, has great support for full-text search, and many features you like. On the other side, a relational database. It has transactions, relational capabilities, implements standards, and lots of developers are familiar with it. Each is a great datastore targeting specific needs. What if you have many needs? What if you want both? Transactions, relations <em>and</em> scale; full-text search <em>and</em> SQL. Preferably without headaches.</p> <p>Enters Hibernate Search. This Java library allows to define a mapping from Hibernate ORM entities to Elasticsearch documents, to transparently index entities as they are persisted in the ORM, and to conveniently query the index through APIs that make the most of a mixed entity/document model. Doing so, it solves the problems that arise when synchronizing data from a relational database to Elasticsearch:</p> <ul> <li>Entities are generally too small to be mapped directly to a useful Elasticsearch document: you need to map <em>trees</em> of entities to a single document. How to handle complex mappings, i.e. how to infer that when entity A is written to, then entity D, three relations away, needs to be reindexed?</li> <li>The database cannot be fully reindexed every minute: synchronization needs to be smart. How to accurately detect database changes without adding boilerplate everywhere in database writing code?</li> <li>The database may be transactional, but Elasticsearch is not. How to correctly handle transactions, generating documents and sending indexing commands at just the right time?</li> </ul> <p>In this talk, I will demonstrate how Hibernate Search 6, the new major version of Hibernate Search currently in development, can be used in an application based on Hibernate ORM.</p> PUBLIC CONFIRMED Search https:/fosdem.org/2019/schedule/event/hibernate_search_6/ K.3.201 Yoann Rodiere PUBLISH 8757@FOSDEM19@pentabarf.org 8757 ux_overhaul_ooni ux_overhaul_ooni Designing for Activism An overview of the UX overhaul of OONI Probe en en_US Open Source Design 2019-02-02 12:00:00 +0100 2019-02-02 12:20:00 +0100 00:20:00:00 20190202T120000 20190202T122000 00:20:00:00 Designing for Activism- An overview of the UX overhaul of OONI Probe <p>How do you design a user experience to guide both grassroot contributors as well as the advanced data researchers?

Over the years, several filtering frameworks have been added to Linux. While at the lower level, ethtool can be used to configure N-tuple rules on the receive side for the hardware, the upper layers of the stack got equipped with rules for firewalling (Netfilter), traffic shaping (TC), or packet switching (Open vSwitch for example).</p> <p>This presentation reviews the needs for those filtering frameworks and the particularities of each one. Then it focuses on the changes brought by eBPF and XDP in this landscape: as BPF programs allow for very flexible processing and can be attached very low in the stack—at the driver level, or even run on the NIC itself—they offer filtering capabilities with no precedent in terms of performance and versatility in the kernel. Lastly, the third part would explore potential leads in order to create bridges between the different rule formats and to make it easier for users to build their filtering eBPF programs.</p> PUBLIC CONFIRMED Software Defined Networking https:/fosdem.org/2019/schedule/event/network_filtering_with_bpf/ H.2214 Quentin Monnet PUBLISH 8715@FOSDEM19@pentabarf.org 8715 opengreffe opengreffe OpenGreffe Decentralised company register for decentralised companies en en_US Blockchain and Crypto Currencies 2019-02-03 12:10:00 +0100 2019-02-03 12:25:00 +0100 00:15:00:00 20190203T121000 20190203T122500 00:15:00:00 OpenGreffe- Decentralised company register for decentralised companies <p>A company register is a centrepiece of the legal existence of firms in a given country.

With an increasing gap between CPU and memory speed, the memory accesses themself now represent one of the largest performance impact which increase the impact of the memory layout on performance. On the other side, the memory size available is still growing with now easily reachable TB memory systems which make a huge space to handle with a management cost which if badly done can become non neglectable.</p> <p>In order to better address those questions I will present two tools I developped during my post-docs arround the HPC fields: MALT [MALloc Tracker] and NUMAPROF.</p> <p>MALT is dedicated to memory management analysis by tracking calls to malloc and annotate the source code of a C/C++/Fortan application. It provides many metrics arround memory management, like the allocations sizes, lifetime, time charts to better understand the memory behavior of you application in them of memory management. The tool comes with the nice web based graphical interface.</p> <p>NUMAPROF is built arround the same code base to provide NUMA (Non Uniform Memory Access) performance analysis by tracking the memory location of every access in a NUMA system by using binary instrumentation. It is usefull to easily track the remote of unbound memory access which can be a source of large performance loss in such systems.

It allows the operating system to interact with the supervisor execution environment (SEE). The SEE always runs in higher privileged mode than the supervisor OS. It can be a simple bootloader in low-end hardware platform, a hypervisor-provided virtual machine in a high-end server, or simply machine mode software in bare metal systems. An unchecked rapid development of many RISC-V systems could lead to incompatibilities between different systems SEE, preventing the use of a common OS binary image.</p> <p>The RISC-V ISA has defined SBI to provide a cleaner interface for the supervisor OS which makes virtualization and bring-up of new hardware platforms much easier. In hypervisor extended supervisor (HS) mode, an OS or hypervisor interacts with the machine through the same SBI as an OS normally does from supervisor mode. An HS-mode hypervisor is expected to implement the SBI for its virtualized supervisor (VS) mode guest. The current RISC-V SBI only defines a few mandatory functions such as inter-processor interrupts (IPI) interface, reprogramming timer, serial console, and memory barrier instructions. Many important functionalities such as CPU/system power management are not yet defined due to difficulties in accommodating modifications without breaking backward compatibility with the current interface.</p> <p>This talk presents the ongoing work to make SBI an extensible yet robust specification. The proposal to extend SBI is based on the foundation policy of RISC-V i.e. modularity and openness. It will always be backward compatible with previous versions including the existing aka legacy version. To achieve that, the focus will be only to develop a Base SBI extension that will contain feature list, version and vendor type queries. Once that is ratified, the future extension such as CPU/system power management, vendor extensions can be developed in parallel. The use cases and calling convention of these extensions will be discussed in details. We will also talk about a reference implementation i.e. OpenSBI for the SBI specification. This project will be licensed under most permissive software license which will allow everybody to reuse the OpenSBI code base in their favorite software eco-system in whatever way choose to do so. This will help in reducing SBI fragmentation in future as well.</p> <p>In the spirit of the open design nature of RISC-V, the goal of this presentation is to continue the open discussion leading to the formalizing RISC-V SBI specification simplifying both hardware and software designs and doing so, contributing to further development of the RISC-V ecosystem.</p> PUBLIC CONFIRMED RISC-V https:/fosdem.org/2019/schedule/event/riscvsbi/ AW1.126 Atish Patra PUBLISH 8235@FOSDEM19@pentabarf.org 8235 ml_on_code_deduplicating_pga ml_on_code_deduplicating_pga Deduplication on large amounts of code Fuzzy deduplication of PGA using source{d} stack en en_US ML on Code 2019-02-03 12:30:00 +0100 2019-02-03 13:10:00 +0100 00:40:00:00 20190203T123000 20190203T131000 00:40:00:00 Deduplication on large amounts of code- Fuzzy deduplication of PGA using source{d} stack <p>In this talk I will discuss how to deduplicate large amounts of source code using the source{d} stack, and more specifically the Apollo project.

However, measuring latency correctly is not easy. In contrast to familiar metrics like CPU utilization or request counts, the "latency" of a service is not easily expressed in numbers. Percentile metrics have become a popular means to measure the request latency, but have several shortcomings, especially when it comes to aggregation. The situation is particularly dire if we want to use them to specify Service Level Objectives (SLOs) that quantify the performance over a longer time horizons. In the talk we will explain these pitfalls, and suggest three practical methods how to implement effective Latency SLOs.</p> PUBLIC CONFIRMED Monitoring and Observability https:/fosdem.org/2019/schedule/event/latency_slos_done_right/ UB2.252A (Lameere) Heinrich Hartmann PUBLISH 8891@FOSDEM19@pentabarf.org 8891 improving_libreoffice_quality_together improving_libreoffice_quality_together Improving LibreOffice quality together A summary of what happened in 2018 en en_US Open Document Editors 2019-02-02 12:30:00 +0100 2019-02-02 13:00:00 +0100 00:30:00:00 20190202T123000 20190202T130000 00:30:00:00 Improving LibreOffice quality together- A summary of what happened in 2018 <p>Improving LibreOffice quality together.

However, ever since row-based replication was introduced, it has also been widely used as an integration point between a MySQL server and other components in an IT infrastructure. It is often used as a capture-data-changes stream, as a source of data for extract-transform-load operations or even as an event notification trigger (e.g., propagating transaction information to proxy layers).</p> <p>Commonly deployed setups revolve around collecting/subscribing to data changes and propagating these to downstream consumers through a message bus, like Kafka for instance.</p> <p>This session will present such use cases, highlighting the additional metadata added to the binary log in the latest releases, explain how to efficiently make the most out of these and how to optimize the implementation of a change capture procedure.

Machine learning (ML) systems are only as good as the data they are trained on and getting the data in the right format at the right time is a challenge. ML systems are trained using sets of features, a feature can be as simple as the value of a column in a database entry, or it can be a complex value that is computed from diverse sources.</p> <p>A feature store is a central vault for storing documented and curated features, ideally with support for access control. A feature store enables automatic feature analysis and monitoring, feature sharing across models and teams, feature discovery, feature backfilling, and feature versioning. The feature store is a data management layer that fills an important piece in the modern machine learning infrastructure, it empowers enterprises to scale their machine learning workflows and make full use of their investment in machine learning.</p> <p>In this talk, we will present key points on how to take your machine learning workflow to the next level using a feature store, and demonstrate how the feature store fits into the larger machine learning pipeline. We will introduce HopsML, an open-source, end-to-end machine learning pipeline built on the world's most fastest and most scalable Hadoop distribution, Hops Hadoop. With HopsML you can build production-ready machine learning pipelines using open source software, where features are stored in a shared feature store that is automatically backfilled as new data arrive, where machine learning models can be trained on datasets in the order of billions examples using distributed deep learning, where data scientists can follow engineering principles by using versioned and reproducible experiments, and where models can be automatically deployed in an elastic manner using auto-scaling.</p> PUBLIC CONFIRMED HPC, Big Data and Data Science https:/fosdem.org/2019/schedule/event/feature_store/ UA2.118 (Henriot) Kim Hammar PUBLISH 8826@FOSDEM19@pentabarf.org 8826 containers_lttng containers_lttng A follow-up on LTTng container awareness System level tracing in a containerized world en en_US Containers 2019-02-03 12:50:00 +0100 2019-02-03 13:10:00 +0100 00:20:00:00 20190203T125000 20190203T131000 00:20:00:00 A follow-up on LTTng container awareness- System level tracing in a containerized world <p>Follow up on the work that was done since last year's 'LTTng: The road to container awareness' presentation.

Those who have models and generate data from those models, a process known as 'simulation', and those who have data and infer models from the data ('analytics'). The former often originate from disciplines such as Engineering, Physics, or Climatology, while the latter are most often active in Remote sensing, Bioinformatics, Sociology, or Management.</p> <p>Simulations often require large amount of computations so they are often run on generic High-Performance Computing (HPC) infrastructures built on a cluster of powerful high-end machines linked together with high-bandwidth low-latency networks. The cluster is often augmented with hardware accelerators (co-processors such as GPUs or FPGAs) and a large and fast parallel filesystem, all setup and tuned by systems administrators. By contrast, in analytics, the focus is on the storage and access of the data so analytics is often performed on a BigData infrastructure suited for the problem at hand. Those infrastructure offer specific data stores and are often installed in a more or less self-service way on a public or private 'Cloud' typically built on top of 'commodity' hardware.</p> <p>Those two worlds, the world of HPC and the world of BigData are slowly, but surely, converging. The HPC world realises that there are more to data storage than just files and that 'self-service' ideas are tempting. In the meantime, the BigData world realises that co-processors and fast networks can really speedup analytics. And indeed, all major public Cloud services now have an HPC offering. And many academic HPC centres start to offer Cloud infrastructures and BigData-related tools.</p> <p>This talk will focus on the latter point of view and review the tools originating from the BigData and the ideas from the Cloud that can be implemented in a HPC context to enlarge the offer for scientific computing in universities and research centres.</p> PUBLIC CONFIRMED HPC, Big Data and Data Science https:/fosdem.org/2019/schedule/event/convergence_hpc_big_data/ UA2.118 (Henriot) Damien François PUBLISH 8456@FOSDEM19@pentabarf.org 8456 typescript_time_to_migrate typescript_time_to_migrate TypeScript-It's time to migrate! en en_US .NET and TypeScript 2019-02-02 13:15:00 +0100 2019-02-02 13:30:00 +0100 00:15:00:00 20190202T131500 20190202T133000 00:15:00:00 TypeScript-It's time to migrate! <p>TypeScript adoption it's been a reality in the last years.

But in the last couple of years this has changed, and it's looking more and more like Vulkan will take over the throne. This means that we currently need two graphics drivers for each GPU, one per API. But it's not like the available workforce for opensource drivers all of a sudden doubled, so this leaves us with a scalability problem.</p> <p>To remedy this, we have started working on Zink, a new Mesa Gallium driver that implements OpenGL on top of Vulkan. This means that in the future, GPU vendors can focus on one, high-performance Vulkan driver, and leave OpenGL as a legacy/compatibility feature. This does come at a loss of performance, but this might not be as bad as one would fear.</p> <p>This approach also has some extra interesting benefits when virtualizing GPU access, where the channel through the VM to the GPU needs to be thoroughly vetted for security issues. Allowing this to be done once rather than twice has obvious benefits.</p> <p>This talk will cover what the current status of the project is, what problems are on the horizon, and where it'll hopefully go in the future.</p> PUBLIC CONFIRMED Hardware Enablement https:/fosdem.org/2019/schedule/event/zink/ K.4.401 Erik Faye-Lund PUBLISH 8109@FOSDEM19@pentabarf.org 8109 js_teaching_tool js_teaching_tool JavaScript for open computing education en en_US Javascript 2019-02-03 13:30:00 +0100 2019-02-03 13:55:00 +0100 00:25:00:00 20190203T133000 20190203T135500 00:25:00:00 JavaScript for open computing education <p>Prof. dr.

The reason is that developing a specializer for a new language remains still a from-scratch endeavor, and it's hard.</p> <p>It is the lack of general-purpose flexible program specialization tools that often leads projects to creating custom just-in-time compilers for their specific use cases. These compilers, even if based on mature compiler infrastructures such as LLVM's, immediately become way harder to develop and maintain than simple interpreters they make obsolete. In many cases, however, program specialization could bring the proverbial 80% of the benefits for a fraction of the cost, while maintaining simplicity and testability of the original design.</p> <p>It is our belief that developing a specializer for a new language should be as easy as adding some supporting syntactic and semantic definitions to a language front-end and reusing an existing specializer in the middle end.</p> <p>Such a language-independent specializer preferably has to:</p> <ul> <li>remove as much interpretation overhead as possible, and add no extra interpretation overhead of its own;</li> <li>be able to produce both interpreters and compilers from the same code base, to enable gradual transition and to preserve debugging and testing properties of the original source code;</li> <li>include a binding-time analysis component to simplify binding-time improvements of the source program;</li> <li>be guided by annotations embedded in the source program as opposed to external annotations, to ease development and maintenance;</li> <li>support multiple compilation stages to take advantage of as many specialization points as necessary;</li> <li>be flexible enough with resource management to fit in both managed and unmanaged environments.</li> </ul> <p>We will present the design and the prototype implementation of a multi-stage offline specializer generator that ticks most of these boxes. The generator is based on LLVM and runs in compile time along with the compilation of a source program. It is controlled by intrinsics and function and parameter attributes in LLVM IR. Being developed in the middle-end of the LLVM optimizer, the specializer generator can be used with any language front-end. We will talk about some elements of its design, its limitations, and ways to improve.</p> PUBLIC CONFIRMED LLVM https:/fosdem.org/2019/schedule/event/llvm_mix/ K.4.201 Eugene Sharygin PUBLISH 8411@FOSDEM19@pentabarf.org 8411 vai_monitoring_kubernetes vai_monitoring_kubernetes Monitoring Kubernetes and Virtualization en en_US Virtualization and IaaS 2019-02-02 13:30:00 +0100 2019-02-02 14:00:00 +0100 00:30:00:00 20190202T133000 20190202T140000 00:30:00:00 Monitoring Kubernetes and Virtualization <p>Now that Kubevirt, a converged infrastructure that brings virtualization on top of Kubernetes came into the world, it’s time to take a look on the monitoring aspects of this solution.

Two classes of faults dominate: runtime errors like buffer overflows, and logic errors in protocol state machines. The main reasons for runtime errors is the use of unsafe programming languages. Better alternatives with formal guarantees like Rust, SPARK or Frama-C exist, but re-implementing complex protocols means a lot of effort. Logic errors are caused by the complexity of protocols and imprecise specifications in natural language.</p> <p>RecordFlux is a framework for the secure implementation of communication protocols. From a formal protocol specification written in a domain-specific language the tools generate SPARK code, for which the absence of runtime errors can be proven automatically. In the future RecordFlux will also allow the specification of dynamic protocol semantics and support formal correctness proofs for protocol state machines. In this talk we give an overview of the current state and speak about an upcoming project that uses RecordFlux for a complex real-world application, the compartmentalized implementation of TLS 1.3 for component-based operating systems.</p> PUBLIC CONFIRMED Security https:/fosdem.org/2019/schedule/event/recordflux/ UD2.218A Tobias Reiher PUBLISH 8612@FOSDEM19@pentabarf.org 8612 sdr_equinox sdr_equinox Equinox: A C++11 platform for realtime SDR applications en en_US Free Software Radio 2019-02-03 13:30:00 +0100 2019-02-03 14:00:00 +0100 00:30:00:00 20190203T133000 20190203T140000 00:30:00:00 Equinox: A C++11 platform for realtime SDR applications <p>Equinox: A C++11 platform for realtime SDR applications</p> <p>Equinox is a block programming platform suitable for SDR applications. It is written in C++11 and targets mainly realtime applications. To accomplish that, it exploits the flowgraph topology trying to optimize the scheduling of the different components and the data exchange between them. Using graph analysis algorithms and based on the available CPU cores, overheads like threading synchronization, as well as data dependencies or memory copies can be reduced.</p> <p>At the same time, the platform tries to provide such an abstraction so it can easily adapt on the application requirements. To do so, it provides an abstracted scheduling mechanism, that can be easily extended. Currently there are two available schedulers. A simplified one, trying to equally distribute the number of blocks into the available CPU cores and a more sophisticated one, using the spectral graph partitioning algorithm which targets the minimum data dependencies between different CPU cores. Both of them can be used based on a user defined configuration parameter, without altering the flowgraph. For the DSP, Equinox will utilize the liquid-dsp library, abstracted in a visual block programming way.</p> <p>As block programming platform, it provides a QT5 based GUI (equinox-ui) in order users to be able to develop their application with ease. The UI is responsible for generating the C++ source file and build system, so it can be then compiled and executed.</p> <p>The code is licensed under the GPLv3 license and is available at the https://gitlab.com/equinox-sdr repository.</p> PUBLIC CONFIRMED Free Software Radio https:/fosdem.org/2019/schedule/event/sdr_equinox/ AW1.120 Manolis Surligas PUBLISH 8672@FOSDEM19@pentabarf.org 8672 dotnet_interactive_fsharp_with_jupyter dotnet_interactive_fsharp_with_jupyter Interactive Computing with F# Jupyter en en_US .NET and TypeScript 2019-02-02 13:30:00 +0100 2019-02-02 14:00:00 +0100 00:30:00:00 20190202T133000 20190202T140000 00:30:00:00 Interactive Computing with F# Jupyter <p>Notebooks let you blend code, data, and graphical visualisations to explore and share explanations.

When it comes to interoperability with other formats, notably OOXML, this causes another interesting source of problems: there are features available in the editor that might not be available in the counterpart product and consequently neither in OOXML format. The result might be loss of work time: the user assumes if she saves her carefully crafted document in OOXML it will be retained. In some unlucky cases this might not be true because of differences between the LO feature set and the file format preferred by the user or her peers.</p> <p>My proposed solution to this is a small, simple and gradually extensible one: let's offer a configuration key that might be turned on by system administrators and this in turn would disable elements of the LibreOffice UI that offer features not available in the OOXML file format, or set different defaults in certain situations.</p> PUBLIC CONFIRMED Open Document Editors https:/fosdem.org/2019/schedule/event/preventing_ooxml_interoperability_problems_in_libreoffice/ UA2.114 (Baudoux) Gabor Kelemen PUBLISH 8933@FOSDEM19@pentabarf.org 8933 ada_database ada_database Persistence with Ada Database Objects en en_US Ada 2019-02-02 13:30:00 +0100 2019-02-02 13:50:00 +0100 00:20:00:00 20190202T133000 20190202T135000 00:20:00:00 Persistence with Ada Database Objects <p>The presentation describes how Ada Database Objects helps in connecting to an SQLite/MySQL/PostgreSQL database from Ada.

Special Guests Tensorflow and Apache Spark) <p>Data Science, Machine Learning, and Artificial Intelligence has exploded in popularity in the last five years, but the nagging question remains, “How to put models into production?” Engineers are typically tasked to build one-off systems to serve predictions which must be maintained amid a quickly evolving back-end serving space which has evolved from single-machine, to custom clusters, to “serverless”, to Docker, to Kubernetes. In this talk, we present KubeFlow- an open source project which makes it easy for users to move models from laptop to ML Rig to training cluster to deployment. In this talk we will discuss, “What is KubeFlow?”, “why scalability is so critical for training and model deployment?”, and other topics.</p> <p>Users can deploy models written in Python’s skearn, R, Tensorflow, Spark, and many more. The magic of Kubernetes allows data scientists to write models on their laptop, deploy to an ML-Rig, and then devOps can move that model into production with all of the bells and whistles such as monitoring, A/B tests, multi-arm bandits, and security.</p> PUBLIC CONFIRMED HPC, Big Data and Data Science https:/fosdem.org/2019/schedule/event/kubeflow/ UA2.118 (Henriot) Holden Karau Trevor Grant PUBLISH 7761@FOSDEM19@pentabarf.org 7761 homebrew_2 homebrew_2 Homebrew 2.0.0 en en_US Distributions 2019-02-03 13:45:00 +0100 2019-02-03 14:15:00 +0100 00:30:00:00 20190203T134500 20190203T141500 00:30:00:00 Homebrew 2.0.0 <p>Talk discussion the major features, leadership and community changes accompanying Homebrew 2.0.0 (which will be released at or shortly after FOSDEM 2019).</p> PUBLIC CONFIRMED Distributions https:/fosdem.org/2019/schedule/event/homebrew_2/ K.3.401 Mike McQuaid PUBLISH 8026@FOSDEM19@pentabarf.org 8026 hardware_software_co_design hardware_software_co_design Hardware/Software Co-Design for Efficient Microkernel Execution en en_US Microkernels and Component-based OS 2019-02-03 13:45:00 +0100 2019-02-03 14:20:00 +0100 00:35:00:00 20190203T134500 20190203T142000 00:35:00:00 Hardware/Software Co-Design for Efficient Microkernel Execution <p>While the performance overhead of IPC in microkernel multiserver operating systems is no longer considered a blocker for their practical deployment (thanks to many optimization ideas that have been proposed and implemented over the years), it is undeniable that the overhead still does exist and the more fine-grained the architecture of the operating system is (which is desirable from the reliability, dependability, safety and security point of view), the more severe performance penalties due to the IPC overhead it suffers.

The main ingredients are the precise statement of the problem, an algorithm to solve it, and an assessment of the errors. From algorithm, there is a long journey to a program: the method needs to be more user-friendly (handling of error cases, etc.), has to be implemented in a programming language, and tested. The resulting program is not only a practical product, but also a very precise description of the algorithm. If the reader is a computer, nothing is left to interpretation as long as the translator is correct. In my talk, I would like to introduce an effort to preserve mathematical software: the histoRicalg project, and summarize some of its results.</p> <p>In two decades from 1970 to 1990, there was an upsurge in the writing and publication of mathematical software. Much of this has been collected in subroutine libraries or published in print or in machine readable form. Traditionally, scientific results are published in journals, and journal papers are archived in libraries. However, as programs grew larger, they were no longer printed with the papers, but sent to interested readers on tape, diskettes, or other forms of data storage.</p> <p>The knowledge accumulated in these codes is extensive and valuable. Its preservation, however, is more difficult than that of papers. Storage technologies come and go, programming languages come into fashion, then become forgotten. To preserve the algorithms, one needs to constantly copy their source code from old computers to newer ones and preserve the tools needed to compile them.</p> <p>In this poster, I plan to introduce one effort to preserve mathematical codes: the histoRicalg project. Its primary objective is to find, document, and preserve the originals of the numerical codes that have found their way into the R statistical programming system. In particular, I will summarize my experience with attempts to run the originals of these codes on a modern Linux PC.</p> PUBLIC CONFIRMED Retrocomputing https:/fosdem.org/2019/schedule/event/retro_preserving_algorithms/ K.4.601 Arpad Laszlo Lukacs PUBLISH 7602@FOSDEM19@pentabarf.org 7602 monitoring_anon monitoring_anon Privacy-preserving monitoring of an anonymity network Data Collection, Analysis, and Visualisation from the public Tor network en en_US Monitoring and Observability 2019-02-03 13:50:00 +0100 2019-02-03 14:15:00 +0100 00:25:00:00 20190203T135000 20190203T141500 00:25:00:00 Privacy-preserving monitoring of an anonymity network- Data Collection, Analysis, and Visualisation from the public Tor network <p>The goals of a privacy and anonymity network like Tor are not easily combined with extensive data gathering, but at the same time data is needed for monitoring, understanding, and improving the network.

The rapidly growing Internet of Things is no exception. This talk will discuss why we think that JavaScript is a good option to kick-start building your own Internet of Things. Solutions we have been used for building an end to end IoT system using JavaScript will be discussed. An introduction to JerryScript, an ultra-light JavaScript engine from Samsung, will be given to address the issue of resource restriction in embedded devices. It is followed by a look at JavaScript platforms based on JerryScript that provide direct JavaScript APIs to developers.

Unfortunately, there are many more challenges that are not often talked about, like the significantly decreased development speed due to all the code being implemented on the client side, the increased difficulty and complexity in upgrading the protocol and many others.</p> <p>In this talk Tom will use EteSync as an example for a secure application to show some of the more interesting challenges he faced while creating it, and new challenges that he encountered as the user-base grew and the protocol evolved. Tom will also cover some of the issues that affect EteSync today, how they will be addressed in the future, where EteSync is going, and what's currently holding it back.

Numba however puts some restrictions on the code that can be accelerated. These restrictions can force you to compromise, making your code less readable or more difficult to integrate with the rest of your code. This tradeoff makes Numba less attractive. In this talk I'll share what I've learned integrating Numba in our simulator.

The session will go over the ONOS modular architecture, its main tenets, use cases, and applications. It will describe the APIs that enable programmability in the network, both at the control and data planes.</p> <p>The talk will detail how your needs in network programmability are easily solved by new apps, REST APIs and other tools that the ONOS platform offers. ONOS has become production ready. The code undergoes strict and high-quality testing. ONOS is currently in production in data centers managing traffic on thousands of customers in mission critical networks. The talk will highlight how ONOS serves as a building block for opensource and commercial projects, such as Software enabled Broadband Access (SEBA), SONA for networking in Openstack and others. ONOS is also deployable in a kubernetes environment through docker containers. ONOS also keeps pushing the boundary of new technologies, for example enabling data plane programmability through P4 and P4Runtime and by providing support and connectivity to edge cloud deployments to better offer low-latency, personalised and secure services to the end-users.</p> <p>Finally, the talk will dive into the great ONOS open-source community, its strengths and how to become part of it.</p> PUBLIC CONFIRMED Software Defined Networking https:/fosdem.org/2019/schedule/event/onos_introduction/ H.2214 Laszlo Papp PUBLISH 8766@FOSDEM19@pentabarf.org 8766 freebsd_graphics freebsd_graphics FreeBSD Graphics en en_US BSD 2019-02-02 14:05:00 +0100 2019-02-02 14:40:00 +0100 00:35:00:00 20190202T140500 20190202T144000 00:35:00:00 FreeBSD Graphics <p>FreeBSD Graphics - what is it, and how does it work?</p> <p>In this presentation I will talk about the FreeBSD Graphics effort and the team behind it.

For such systems, compiled code density is a critical factor, particularly for deeply embedded and low power systems, where memory may be very constrained. Architectures in this space are often designed to improve code density. Thus ARM has its Thumb-2 instructions and RISC-V has its compressed instructions.</p> <p>If compiler tool chains are to generate compact code, we need to be able to measure how well we are doing. In this talk I shall present measurements of code density for 32-bit RISC-V, ARM and ARC architectures using the GCC and Clang/LLVM compiler tool chains using the BEEBS benchmark suite for deeply embedded systems (http://beebs.eu/). I shall show how confounding factors (such as emulation library implementation and C run-time startup) can be eliminated from such measurements, to ensure the results are meaningful.</p> <p>The purpose of this exercise is not to show that any one architecture is "best" but to provide insight which will drive compiler optimization for code density. I shall use the data to highlight areas where the RISC-V compiler tool chain can be improved, drawing on customer work carried out by Embecosm during 2018.</p> PUBLIC CONFIRMED RISC-V https:/fosdem.org/2019/schedule/event/riscvcompact/ AW1.126 Jeremy Bennett PUBLISH 8484@FOSDEM19@pentabarf.org 8484 set_versioned_package_dependencies set_versioned_package_dependencies Set-versioned package dependencies addressing the problem of shared library updates en en_US Distributions 2019-02-03 14:15:00 +0100 2019-02-03 14:45:00 +0100 00:30:00:00 20190203T141500 20190203T144500 00:30:00:00 Set-versioned package dependencies- addressing the problem of shared library updates <p>Set-versioned package dependencies is a free software technology invented in ALT and implemented in ALT package repositories and distributions since 2010 to prevent breakages caused by updates of shared libraries containing incompatible changes.</p> PUBLIC CONFIRMED Distributions https:/fosdem.org/2019/schedule/event/set_versioned_package_dependencies/ K.3.401 Dmitry Levin PUBLISH 8591@FOSDEM19@pentabarf.org 8591 ohw_rpi ohw_rpi Making Open Source Hardware for Retrogaming on Raspberry Pi en en_US Retrocomputing 2019-02-02 14:15:00 +0100 2019-02-02 14:40:00 +0100 00:25:00:00 20190202T141500 20190202T144000 00:25:00:00 Making Open Source Hardware for Retrogaming on Raspberry Pi <p>Raspberry Pi, the most popular single board computer for hobbyists and students, is an affordable and widely used platform for retrogaming.

It organized multiple events, led various public campaigns and even took part in defining some local standards. But over the years, many of the early members have moved on and the activities slowly dwindled. By 2014, all that remained was several old-timers debating over a mailing list and a yearly gathering that was becoming difficult to organize. There were barely enough volunteers left to fill the legal requirements for running a non-profit.</p> <p>Ironically, just as Open Source was becoming popular, the organization was fighting for its life. An emergency general assembly was called to discuss the possibility of disbanding the organization. With a narrow margin of 4:2, the members decided to continue operating. From that point, the organization started on a path of growing its activities and working on its rejuvenation, attracting new members and adapting to the current trends in the FOSS world.</p> <p>In 2018, Hamakor provided the platform for organizing multiple conferences, held regular monthly open source hack nights, and got to the point of working towards hiring it's first paid employee.</p> <p>We will discuss what worked, what didn't work, the lessons learned, what challenges we faced along the way and what are the challenges ahead as we continue to grow.</p> <p>While the talk is a case study of one organization, much of the content will be relevant to other mature organizations facing similar situations, and to younger organizations that wish to avoid making into the same mistakes we made.</p> PUBLIC CONFIRMED Community devroom https:/fosdem.org/2019/schedule/event/community_back_from_the_dead/ UB5.132 Tomer Brisker PUBLISH 7904@FOSDEM19@pentabarf.org 7904 sustain_in_open_source_with_gitcoin sustain_in_open_source_with_gitcoin Sustain in Open Source with Gitcoin Gitcoin is a decentralized application where you can use various ERC-20 tokens to grow and sustain in Open Source and many other things. en en_US Blockchain and Crypto Currencies 2019-02-03 14:20:00 +0100 2019-02-03 14:40:00 +0100 00:20:00:00 20190203T142000 20190203T144000 00:20:00:00 Sustain in Open Source with Gitcoin- Gitcoin is a decentralized application where you can use various ERC-20 tokens to grow and sustain in Open Source and many other things. <p>Open Source Software and Open Source contributors provide for a massive percentage of today's softwares and web and other technical ecosystems.

For instance, the detection of commits that fulfill a given criterion (e.g., bugfixing commits) is one of the most frequent tasks done to understand the software evolution. However, to our knowledge, there is not open-source tools that, given a Git repository, returns all the instances of a given source code change pattern. In this talk, we present Coming, a tool that takes an input a Git repository and mines instances of source code change patterns on each commit. For that, Coming computes fine-grained changes between two consecutive revisions, analyzes those changes to detect if they correspond to an instance of a change pattern (specified by the user using XML). Finally, after analyzing all the commits, Coming presents the frequency of code changes and the instances found on each commit.</p> PUBLIC CONFIRMED ML on Code https:/fosdem.org/2019/schedule/event/ml_on_code_coming/ H.2213 Matias Martinez PUBLISH 8785@FOSDEM19@pentabarf.org 8785 lucene_upgrade_jira_8 lucene_upgrade_jira_8 Lucene Upgrade in Jira 8.0 How we fought and killed the code debt beast en en_US Search 2019-02-03 14:30:00 +0100 2019-02-03 14:55:00 +0100 00:25:00:00 20190203T143000 20190203T145500 00:25:00:00 Lucene Upgrade in Jira 8.0- How we fought and killed the code debt beast <p>Jira 8.0 will be shipped with Lucene 7.3.

Consequently, there an abundance of graph processing tools which build on distributed data processing frameworks, including <a href="https://spark.apache.org/graphx/">Spark GraphX</a>, <a href="https://flink.apache.org/news/2015/08/24/introducing-flink-gelly.html">Flink Gelly</a> and <a href="https://giraph.apache.org/">Giraph</a> (which runs on Hadoop). According to a <a href="https://arxiv.org/abs/1607.02646">recent survey</a>, most of these systems build on the <em>vertex-centric programming model</em>, originally introduced in Google’s <a href="https://ai.google/research/pubs/pub37252">Pregel paper</a>. This model defines graph analytical algorithms in terms of vertices communicating with their neighbours through message passing, which allows both easy parallelization (for the systems) and intuitive formalization of the computation (for developers). While these systems indeed exhibit horizontal scalability, they introduce numerous inefficiencies requiring a large amount of resources even for moderately sized graphs. Most practical applications only use graphs up to a few hundred million vertices and edges, which can now be stored comfortably on a single machine. For such graphs, it is worth investigating techniques that allow their evaluation without the additional cost and complexity of operating a distributed cluster.</p> <h2>GraphBLAS</h2> <p>The <a href="http://graphblas.org/">GraphBLAS</a> initiative is an effort to design a set of standard building blocks that allow users to formulate graph computations <a href="http://bookstore.siam.org/se22/">in the language of linear algebra</a>, using operations on sparse adjacency matrices defined on custom semirings. Since its inception, GraphBLAS has been implemented for multiple languages (e.g. <a href="http://faculty.cse.tamu.edu/davis/suitesparse.html">C</a>, <a href="https://github.com/cmu-sei/gbtl">C++</a>, and <a href="https://github.com/Accla/graphulo">Java</a>). Additionally, GraphBLAS is being designed in collaboration with hardware vendors (such as Intel and Nvidia) to define a standardized set of interfaces, which will allow building specialized hardware components for graph processing in the future.</p> <h2>Multiplex graph metrics</h2> <p>Graph analysis has a significant overlap with <em>network science</em>, a field that aims to uncover the hidden structural properties of graphs and determine the interplay between their vertices. Most works in network science only study homogeneous (<em>monoplex</em>) graphs, and do not distinguish between different types of vertices and edges. We believe this abstraction is wasteful for most real-life networks, which are heterogeneous (<em>multiplex</em>) and emerge by different types of interactions. To illustrate such analyses, we calculated <a href="https://arxiv.org/abs/1308.3182">multiplex clustering metrics</a> on the <a href="https://offshoreleaks.icij.org/pages/database">Paradise papers data set</a> to find interesting entities that were engaged in disproportionately high levels of activities with their interconnected neighbours. We found that even on this relatively small data set (2M vertices and 3M edges), naive implementations did not terminate <em>in days</em>. Hence, we adapted techniques from GraphBLAS to optimize the computations to finish in a few minutes.</p> <h2>Outline of the talk</h2> <p>This talk gives a brief overview of how linear algebra can be used to define graph computations on monoplex graphs, and how we applied it to <a href="https://www.db.bme.hu/preprints/tdk2018-matrix-based-analysis-of-multiplex-graphs.pdf">speedup the calculation of multiplex graph metrics</a>.

Evaluating search quality is important both to understand and size the improvement or regression of your search application across the development cycles, and to communicate such progress to relevant stakeholders. In the industry, and especially in the open source community, the landscape is quite fragmented: such requirements are often achieved using ad-hoc partial solutions that each time require a considerable amount of development and customization effort. To provide a standard, unified and approachable technology, we developed the Rated Ranking Evaluator (RRE), an open source tool for evaluating and measuring the search quality of a given search infrastructure. RRE is modular, compatible with multiple search technologies and easy to extend. The focus of the presentation will be on a live demo showing an example project with a set of initial relevancy issues that we will solve iteration after iteration: using RRE output feedbacks to gradually drive the improvement process until we reach an optimal balance between quality evaluation measures.</p> PUBLIC CONFIRMED Search https:/fosdem.org/2019/schedule/event/rated_ranking_evaluator/ K.3.201 Andrea Gazzarini Alessandro Benedetti PUBLISH 8823@FOSDEM19@pentabarf.org 8823 online_under_the_hood online_under_the_hood Online - under the hood How to bring LibreOffice to your web app en en_US Open Document Editors 2019-02-02 15:00:00 +0100 2019-02-02 15:30:00 +0100 00:30:00:00 20190202T150000 20190202T153000 00:30:00:00 Online - under the hood- How to bring LibreOffice to your web app <p>The Online code-base can bring LibreOffice into an iframe in your web app. Come and hear how this works, how to integrate it with your software, and about all the options and tweaks that go with this.</p> PUBLIC CONFIRMED Open Document Editors https:/fosdem.org/2019/schedule/event/online_under_the_hood/ UA2.114 (Baudoux) Michael Meeks PUBLISH 8860@FOSDEM19@pentabarf.org 8860 data_modeling_normalization_and_denormalization data_modeling_normalization_and_denormalization Data Modeling, Normalization and Denormalization en en_US PostgreSQL 2019-02-03 15:00:00 +0100 2019-02-03 15:50:00 +0100 00:50:00:00 20190203T150000 20190203T155000 00:50:00:00 Data Modeling, Normalization and Denormalization <p>As a developer using PostgreSQL one of the most important tasks you have to deal with is modeling the database schema for your application.

Weaknesses in TLS 1.2 and below, as well as pressure to improve the protocol's efficiency, lead the Internet Engineering Task Force (IEFT) to engage in development of a new version of the protocol, namely TLS 1.3. In the design of TLS 1.3, the IETF welcomed analyses of the protocol prior to its official release, with the intention of remedying flaws and weaknesses before users would be affected. This "analysis-prior-to-deployment" design process was in sharp contrast to previous versions of the protocol. In this talk I will present two analyses of TLS 1.3 using the Tamarin prover, a state-of-the-art formal methods tool designed specfically for cryptographic protocol analysis. The first analysis, of draft 10, found a serious attack against the protocol and informed the next draft of this critical protocol. The TLS 1.3 draft, however, was a rapidly moving target, and the second analysis effort, of draft 21, went on to confirm the stability of the protocol, showing that after four years of development, the logical core of the protocol was sound. This confirmation gave the IETF confidence to release the protocol, and it was officially approved in August of 2018.</p> PUBLIC CONFIRMED Mozilla https:/fosdem.org/2019/schedule/event/automated_analysis_of_tls_1_3/ UD2.208 (Decroly) Thyla van der Merwe PUBLISH 7741@FOSDEM19@pentabarf.org 7741 sip3 sip3 VoIP Troubleshooting and Monitoring with SIP3 Twenty Thousand MPS under the SIP: VoIP network troubleshooting and monitoring simplified en en_US Real Time Communications (RTC) 2019-02-03 15:15:00 +0100 2019-02-03 15:35:00 +0100 00:20:00:00 20190203T151500 20190203T153500 00:20:00:00 VoIP Troubleshooting and Monitoring with SIP3- Twenty Thousand MPS under the SIP: VoIP network troubleshooting and monitoring simplified <p>An exciting journey from troubleshooting to monitoring or how VoIP network monitoring can simplify troubleshooting and shorten customer tickets resolution time.</p> PUBLIC CONFIRMED Real Time Communications (RTC) https:/fosdem.org/2019/schedule/event/sip3/ H.1309 (Van Rijn) Oleg Agafonov PUBLISH 8779@FOSDEM19@pentabarf.org 8779 xanadu_strawberry_fields xanadu_strawberry_fields Strawberry Fields - software for photonic quantum computing en en_US Quantum Computing 2019-02-02 15:15:00 +0100 2019-02-02 16:00:00 +0100 00:45:00:00 20190202T151500 20190202T160000 00:45:00:00 Strawberry Fields - software for photonic quantum computing <p>n this talk, we introduce Strawberry Fields, an open-source quantum software library for light-based quantum computers.

The library also contains built-in examples of several paradigmatic algorithms, including teleportation, (Gaussian) boson sampling, instantaneous quantum polynomial, Hamiltonian simulation, and variational quantum circuit optimization.</p> PUBLIC CONFIRMED Quantum Computing https:/fosdem.org/2019/schedule/event/xanadu_strawberry_fields/ AW1.121 Joshua Izaac PUBLISH 7504@FOSDEM19@pentabarf.org 7504 geo_streetview geo_streetview OpenTrailView 360 FOSS StreetView for hikers en en_US Geospatial 2019-02-03 15:20:00 +0100 2019-02-03 15:50:00 +0100 00:30:00:00 20190203T152000 20190203T155000 00:30:00:00 OpenTrailView 360- FOSS StreetView for hikers <p>OpenTrailView is a project to create a StreetView-like application by walkers with contributors providing stitched 360-degree panoramas of locations on hiking trails. First discussed at State Of the Map Girona 2010, the project has been dormant for several years due to the high barrier of entry; at the time contributors had to manually stitch photos to produce a panorama using third-party stitching software. The recent availability of 360-degree cameras with auto-stitching has revived the author's interest in the project.

Ansible is a great tool for system management, but keeping Ansible playbooks working across major distribution version upgrades can be challenging due to this interface instability. We present Linux System Roles (github.com/linux-system-roles) which allow to manage RHEL, CentOS and Fedora with sufficient abstraction to enable using the same playbooks for different releases and to avoid the need of changing playbooks due to implementation changes. The main difficulty of this approach is getting the interface right to avoid the need of incompatible changes in the future.

Current cloud infrastructure allows to implement cheap microservices by hosting them in VMs. To leverage host resources, VMs are launched on demand, i.e., when the microservice is idle, the VM is shutdown and it is only powered on when a request arrives. In this context, the time that takes the VM to be ready and serves incoming requests becomes very important. We have identified two problems that prevent VMs to start up on time: first, the initialization of the hypervisor, and second, the size of the image. In this talk, we present three approaches that work around on these problems, i.e., Qboot, NEMU and Firecracker. We evaluate these approaches on a Toro appliance that is a unikernel dedicated to microservices.

This optimization path is available both for native methods implemented as callouts to C code and for methods that are defined in Java. In both cases the method needs to be flagged as a HotspotIntrinsic and provided with a JITted code implementation. The intrinsic implementation defines the hand-crafted definition of as a high-level intermediate representation (IR) graph for the C2 JIT. This means it can be inlined into the IR graph for caller methods, providing even greater opportunities for optimization.</p> <p>This talk will demonstrate how to implement an intrinsic by walking through a specific real-life example that is currently under review as a JEP candidate. It will start by motivating the need for the intrinsic and defining the candidate as a Java method which relies on an underlying native implementation. It will then show how the candidate can be replaced with an intrinsic implementation, working through the changes required in the VM, the JIT compiler front and back end and, ultimately, the assemblers for x86 and AArch64.</p> PUBLIC CONFIRMED Free Java https:/fosdem.org/2019/schedule/event/compiler_instrinsic/ H.1302 (Depage) Andrew Dinn PUBLISH 8361@FOSDEM19@pentabarf.org 8361 ceph_rgw_sync_modules ceph_rgw_sync_modules Exporting Ceph Object Storage data to the outside world RGW Sync Modules for fun & profit! en en_US Software Defined Storage 2019-02-03 15:55:00 +0100 2019-02-03 16:10:00 +0100 00:15:00:00 20190203T155500 20190203T161000 00:15:00:00 Exporting Ceph Object Storage data to the outside world- RGW Sync Modules for fun & profit! <p>RGW (Rados Gateway) is the HTTP REST frontend to Ceph, exposing a S3 and Swift API.

We'll take a brief look into the design of sync modules, peer into the crystal ball for what the future holds and also cover the currently available ElasticSearch and Cloud Sync modules, which allows data to be exported to external clouds supporting a S3 like API including Amazon S3.</p> PUBLIC CONFIRMED Software Defined Storage https:/fosdem.org/2019/schedule/event/ceph_rgw_sync_modules/ H.2214 Abhishek Lekshmanan PUBLISH 8405@FOSDEM19@pentabarf.org 8405 extend_emacs_2019 extend_emacs_2019 Extend Emacs in C or Other Languages en en_US Free Tools and Editors 2019-02-03 15:55:00 +0100 2019-02-03 16:25:00 +0100 00:30:00:00 20190203T155500 20190203T162500 00:30:00:00 Extend Emacs in C or Other Languages <p>Starting with GNU Emacs 25, your favorite editor can now load and execute shared objects at runtime.

Linux and Free and Open Source software killed proprietary UNIXes in bare metal data centers and went on to dominate cloud services to such a point that it has even caused Microsoft to completely change their stance and embrace Linux and Free and Open Source software or risk the future of Azure and arguably the future of their company.</p> <p>Yet in many ways, this dominance has also bred complacence in the community. On top of all of those Linux instances are many proprietary services, abstraction layers and APIs that make cloud services easy to use for developers, but also turn them into the largest-scale proprietary operating system on the planet, where the network is the computer. Left unchecked, this proprietary operating system has the potential to undo the achievements Open Source software has made in the past two decades.</p> <p>The FOSS community has seen this "network is the computer" pattern before with Sun Microsystems and Solaris--a proprietary UNIX operating system that administrators ultimately loaded up with GNU software and free software services before deploying to the data center. Instead of Linux images running your dynamic Rails application or Docker container you ran CGIs in Apache and portable Java apps in Tomcat. Instead of disposable instances you had hot-swappable CPUs and RAM. Instead of S3 you had NFS. Expert users would use well-documented but proprietary CLI tools and libraries to interact with the OS and manage their free software processes. Yet in the end, administrators were subject to the roadmaps, whims, pricing structures, expensive hardware, and overall vendor lock-in from Sun. For all of Sun's talented engineers and sophisticated hardware and software, the freedom and values from Linux and Free and Open Source software combined with low-price commodity hardware ultimately dominated the server room.</p> <p>This keynote is part history lesson and part rallying cry. Proprietary OSes and services aren't dead, they just morphed into the cloud. By remembering why Linux was important in the age of Solaris, we can apply those lessons to cloud services before their proprietary APIs and vendor lock-in risk undoing the freedom, open standards, and overall progress our community has made over the last 20 years.</p> PUBLIC CONFIRMED Keynotes https:/fosdem.org/2019/schedule/event/cloud_is_another_sun/ Janson Kyle Rankin PUBLISH 8030@FOSDEM19@pentabarf.org 8030 pargo pargo Parallel programming in Go for performance with the Pargo library en en_US Go 2019-02-02 16:00:00 +0100 2019-02-02 16:30:00 +0100 00:30:00:00 20190202T160000 20190202T163000 00:30:00:00 Parallel programming in Go for performance with the Pargo library PUBLIC CONFIRMED Go https:/fosdem.org/2019/schedule/event/pargo/ UD2.120 (Chavanne) Pascal Costanza PUBLISH 8072@FOSDEM19@pentabarf.org 8072 dl_parallel_db dl_parallel_db Deep Learning on Massively Parallel Processing Databases en en_US HPC, Big Data and Data Science 2019-02-03 16:00:00 +0100 2019-02-03 16:25:00 +0100 00:25:00:00 20190203T160000 20190203T162500 00:25:00:00 Deep Learning on Massively Parallel Processing Databases <p>In this session we will discuss the use of massively parallel databases for deep learning, drawing on experience from running deep learning frameworks like Keras and TensorFlow with GPU acceleration using free and open source software like Greenplum Database and the Apache MADlib machine learning library.

In this talk we are going to see examples of Open Source Hardware in Academia, current repositories curating these types of projects, and see more technical details of one of these tools, the FlyPi, an open source “all in one” biology lab to perform state-of-the-art methods in neuroscience, built using off-the-shelf components and 3D printed parts, costing 10-20X less then proprietary counterparts.</p> PUBLIC CONFIRMED CAD and Open Hardware https:/fosdem.org/2019/schedule/event/scientific_oshw/ AW1.125 Andre Maia Chagas PUBLISH 8663@FOSDEM19@pentabarf.org 8663 media_libre media_libre How libre can you go?

For the first time, .NET developers will have the ability to directly exercise underlying CPU features, very similar to what C/C++ developers could do with intrinsic functions for their performance critical code. The Intel Hardware Intrinsics in .NET Core include more than 1300 intrinsic functions, which cover the instruction set architecture (ISA) SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AVX, AVX2, FMA, LZCNT, POPCNT, BMI1, BMI2, PCLMULQDQ, and AES. Many of the intrinsic functions are designed for Single Instruction Multiple Data (SIMD) computation, a common used technology to speed up computation intensive algorithms. To illustrate the benefits of using Hardware Intrinsics, we implemented a Structure of Array (SoA) based RayTracer and compared its performance with that of the traditional Array of Structure (AoS) based RayTracer which uses System.Numerics.Vectors. Our experience shows that significant performance improvement is possible when using Hardware Intrinsics for this particular application. Another use case is ML.NET, an open source machine learning framework for .NET developers, which leverages the Intel Hardware Intrinsics to simplify the acceleration of machine learning scenarios.</p> <p>We will give an overview of SIMD and the Intel Hardware Intrinsics in .NET Core. In addition, we will talk about the differences of System.Numerics.Vectors and System.Runtime.Intrinsics, which are the two different ways to use SIMD in .NET Core. we will show live demos on how to use Intel hardware intrinsics. By the end of the presentation, the audience will learn the current status of the Intel Hardware Intrinsics in .NET Core and how to use the Intel Hardware Intrinsics to speed up their code.</p> PUBLIC CONFIRMED .NET and TypeScript https:/fosdem.org/2019/schedule/event/dotnet_intel_intrinsics_netcore/ K.3.201 Han Lee PUBLISH 8760@FOSDEM19@pentabarf.org 8760 improving_smartart_import_in_libreoffice_impress improving_smartart_import_in_libreoffice_impress Improving SmartArt import in LibreOffice Impress en en_US Open Document Editors 2019-02-02 16:00:00 +0100 2019-02-02 16:30:00 +0100 00:30:00:00 20190202T160000 20190202T163000 00:30:00:00 Improving SmartArt import in LibreOffice Impress <p>LibreOffice Impress was capable of importing your SmartArt graphics from PPTX files for a long time.

Thus the purpose of this presentation is to provide a technical overview of the following enhancements: reimplementation of the Singularity core in a combination Go and C; the introduction of the Singularity Image Format (SIF) as a file-based paradigm for encapsulating cryptographically signable and verifiable container images; expansion of the Singularity ecosystem through cloud-hosted services for signing and verifying cryptographic keys for SIF images, remotely building images as well as a repository for storing and sharing images; plus miscellaneous enhancements regarding instance support and networking management. Platform enhancements, together with an expanded and better-enabled container ecosystem, combine to set Singularity apart as the optimal choice for compute-driven workloads wherever they exist. Because the Go-based core and SIF enhancements are essential to the roadmap for Singularity, allusions are made here with respect to standards compliance as well as integration with Kubernetes for container orchestration.</p> PUBLIC CONFIRMED Containers https:/fosdem.org/2019/schedule/event/containers_singularity_update/ UA2.114 (Baudoux) Eduardo Arango PUBLISH 7673@FOSDEM19@pentabarf.org 7673 community_collaboration_open_source_is_the_better_way community_collaboration_open_source_is_the_better_way "Collaboration in Open Source Is the Better Way" en en_US Community devroom 2019-02-03 16:05:00 +0100 2019-02-03 16:35:00 +0100 00:30:00:00 20190203T160500 20190203T163500 00:30:00:00 "Collaboration in Open Source Is the Better Way" <p>Do you wish that your project team was more productive?

RDMA enables the network hardware to directly read and write to memory, without the cpu's involvement. My rust implementation ensures that memory regions are exclusively either owned by client code, or enqueued for use by the underlying RDMA stack. This makes sure that data cannot be changed by hardware while owned by safe rust code, and that user logic cannot mutate data while it is being read by the card. In this talk, I'll go over the design of the library and how it embraces rust's ownership transfer semantics.</p> <p>In rust's safe/<code>unsafe</code> model, the burden of upholding safety guarantees at the <code>unsafe</code> boundary is entirely up to the programmer who's writing the wrappers. These guarantees are not formally specified, which makes it harder to reason about the safety of the wrapped <code>unsafe</code> logic; this issue is compounded by the fact that undefined behaviour can seep into safe rust from <code>unsafe</code> code that doesn't match rust's expected semantics. I'll discuss how this improves ergonomics in safe code, but requires careful engineering of <code>unsafe</code> code because it doesn't allow the programmer to reason locally.</p> PUBLIC CONFIRMED Rust https:/fosdem.org/2019/schedule/event/rust_ffi_rdma/ UD2.208 (Decroly) Andrea Lattuada PUBLISH 8957@FOSDEM19@pentabarf.org 8957 countless_beautiful_contributions countless_beautiful_contributions Countless, Beautiful Contributions en en_US Mozilla 2019-02-02 16:10:00 +0100 2019-02-02 16:40:00 +0100 00:30:00:00 20190202T161000 20190202T164000 00:30:00:00 Countless, Beautiful Contributions <p>If you're joining us in the Mozilla devroom, you're likely already passionate about some of the things Mozillans do to build a better internet, contribute to cutting edge technologies or to help teach and share knowledge.

A real world industry example for an escalator use case from a large railroad company underlines the advantages of this approach. In particular, it is shown that even in situations with initially scarce amounts of data accurate predictions can be made using a hybrid analytics approach.

Because of this, a JIT compiler's activities may hinder application throughput and create performance hiccups that can affect quality of service while also complicating resource provisioning. On top of that, it takes a while even for the best JIT compilers to fully compile the performance critical methods of an application to deliver the steady state performance we all expect from the JVM. An approach we are exploring is to decouple the JIT compiler from the rest of the JVM so that JIT compilation can operate as a separate, remote service. This approach opens up the possibility of an elastic, cloud based service offering JIT compilation for many applications, languages, and even different architectures simultaneously.</p> <p>In this talk we will present our experience building an open source JIT-as-a-service prototype based on the Eclipse OpenJ9 JVM.

Software and hardware systems are increasingly complex, vulnerabilities increasingly publicised and attack methodologies increasingly sophisticated. This trend began long ago as did efforts to design and implement foundational technologies to curtail it. The trusted platform module (TPM) is one such technology. It was specifically designed to thwart attacks that aim to steal or misuse sensitive cryptographic keys. Despite its obvious benefits, TPM adoption on OSS platforms was historically minimal.</p> <p>The next iteration of TPM implementations (TPM2) is quickly reaching critical mass in consumer computing platforms. Aiming to capitalize on the availability of TPM2 hardware, the tpm2-software organization on Github (https://github.com/tpm2-software) has coalesced as a community around the implementation of the TCG standard APIs, and their integration into common software tool and infrastructure. This talk will start with an overview of the tpm2-software community, it's history, it's current direction and how new users can get involved. The talk will then shift to discuss the technical details of the TPM2 software stack (TSS2) infrastructure and programming APIs and our current efforts to improve the security properties of OSS through their adoption. Finally, we'll conclude by presenting a use case driving the implementation of a new TPM2 Command Transmission Interface (TCTI) module enabling use of the TPM2 from with the SGX trusted execution environment.</p> PUBLIC CONFIRMED Hardware https:/fosdem.org/2019/schedule/event/tpm2/ Janson Philip Tricca Andreas Fuchs PUBLISH 7860@FOSDEM19@pentabarf.org 7860 organisational_processes_in_decentralized_software organisational_processes_in_decentralized_software Organisational Processes in Decentralized Software roundtable open to decentralized software developers en en_US Decentralized Internet and Privacy 2019-02-02 17:00:00 +0100 2019-02-02 17:30:00 +0100 00:30:00:00 20190202T170000 20190202T173000 00:30:00:00 Organisational Processes in Decentralized Software- roundtable open to decentralized software developers <p>We would like to invite developers for a round table to discuss the specificity of the organization of decentralized software, and to address organizational issues that are crucial for the survival of the projects we love.</p> PUBLIC CONFIRMED Decentralized Internet and Privacy https:/fosdem.org/2019/schedule/event/organisational_processes_in_decentralized_software/ UD2.218A Natacha Roussel zeyev PUBLISH 8090@FOSDEM19@pentabarf.org 8090 v4l2 v4l2 V4L2: A Status Update en en_US Graphics 2019-02-02 17:00:00 +0100 2019-02-02 17:25:00 +0100 00:25:00:00 20190202T170000 20190202T172500 00:25:00:00 V4L2: A Status Update <p>In the past year a lot of work has been put into improving the V4L2 subsystem.

This trend has advanced DPDK, leading to the development of new APIs with the aim of leveraging the heterogeneous features and capabilities of NICs. This level of diversity in PMDs and APIs is a catalyst for an inconsistent development environment, making it difficult for applications to accommodate all types of NIC. To overcome this, we propose DPDK SoftNIC, which is capable of being programmed to build custom NIC pipelines to augment missing features to HW NICs by using advanced DPDK features without requiring an application redesign.

The physical IOMMU guarantees the DMA transfers initiated by the guest are properly translated and isolated.</p> <p>When a virtual IOMMU is exposed to a guest, the physical IOMMU needs to be programmed with the combination of two mappings: the IOVA/GPA mapping programmed by the guest OS and the former GPA/HPA mapping programmed by the hypervisor.</p> <p>Some IOMMU architectures implement nested paging, including the ARM SMMUv3.

Ada mitigates these issues by having much less need for pointers overall (thanks to first-class arrays, parameter modes, generics) and stricter rules for pointer manipulations that limit access to dangling memory. Still, dynamic memory management in Ada may lead to use-after-free, double-free and memory leaks, and dangling memory issues may lead to runtime exceptions.</p> <p>The SPARK subset of Ada is focused on making it possible to guarantee properties of the program statically, in particular the absence of programming language errors, with a mostly automatic analysis. For that reason, and because static analysis of pointers is notoriously hard to automate, pointers have been forbidden in SPARK until now. We are working at AdaCore since 2017 on including pointer support in SPARK by restricting the use of pointers in programs so that they respect "ownership" constraints, like what is found in Rust.</p> PUBLIC CONFIRMED Ada https:/fosdem.org/2019/schedule/event/ada_pointers/ AW1.125 Yannick Moy PUBLISH 8948@FOSDEM19@pentabarf.org 8948 when_perf_html_met_a11y when_perf_html_met_a11y When perf-html Met A11y en en_US Mozilla 2019-02-02 18:30:00 +0100 2019-02-02 19:00:00 +0100 00:30:00:00 20190202T183000 20190202T190000 00:30:00:00 When perf-html Met A11y <p>One in seven people is disabled.</p> <p>And accessible websites (and apps!) enable them to work on an even playing field, while also being more usable for everyone.</p> <p>For the past couple of months, I've been working on improving the accessibility of perf-html, Mozilla's virtuoso profiler.</p> <p>During this talk, I'll be sharing my journey into the world of accessibility and demonstrating how perf-html aims to make Mozilla not just more performant, but also more usable for everyone.</p> <p>Topics covered: Focus, keyboard navigation, semantic HTML, ARIA and Accessibility inspector &lt;3</p> PUBLIC CONFIRMED Mozilla https:/fosdem.org/2019/schedule/event/when_perf_html_met_a11y/ UD2.208 (Decroly) Eva Dovc PUBLISH 8958@FOSDEM19@pentabarf.org 8958 riscvfedora riscvfedora Fedora on RISC-V 64-bit Introduction, Brief Overview and Latest Developments en en_US RISC-V 2019-02-02 18:30:00 +0100 2019-02-02 19:00:00 +0100 00:30:00:00 20190202T183000 20190202T190000 00:30:00:00 Fedora on RISC-V 64-bit- Introduction, Brief Overview and Latest Developments <p>The talk provides introduction to Fedora/RISCV bootstrap efforts for the last 2+ years.

While some solutions require extra extensions, individual PHP builds or a lot of process control management, this talk will show you how to configure and use the built-in PHP FastCGI Process Manager (php-fpm) to execute requests asynchronously in an isolated, tunable process pool and eventually handle their responses in a reactive way.</p> <p>Please note that this talk replaces one entitled "Instant Upgrades with Rector" that was due to have been given by Tomas Votruba, who has sent his apologies but is now unable to attend as he has fallen ill.

It is intended to allow the selective disclosure of information in a document while keeping other parts of the document secret. Typically the result is a document that is suitable for publication or for dissemination to others than the intended audience of the original document. For example, when a document is subpoenaed in a court case, information not specifically relevant to the case at hand is often redacted. Another example is patient information of hospitals, which is distributed to be used for research purposes.</p> <p>A new document redaction feature for Collabora Office is being developed, and it will also be available on the next major version of LibreOffice. This new feature will provide a much more efficient means than the traditional print-redact-scan process, and will try to prevent also the accidental leakage of redacted information by completely removing them in the resulting PDF document, rather than just hiding.</p> PUBLIC CONFIRMED Collaborative Information and Content Management Applications https:/fosdem.org/2019/schedule/event/collab_drwl/ UD2.119 Muhammet Kara PUBLISH 8886@FOSDEM19@pentabarf.org 8886 open_source_design_closing_session open_source_design_closing_session Closing session en en_US Open Source Design 2019-02-02 18:50:00 +0100 2019-02-02 19:00:00 +0100 00:10:00:00 20190202T185000 20190202T190000 00:10:00:00 Closing session <p>We will close the Open Source Design devroom with a few words from all the collective and some comments from the people attending.</p> PUBLIC CONFIRMED Open Source Design https:/fosdem.org/2019/schedule/event/open_source_design_closing_session/ AW1.120 Bernard Tyers Open Source Design Collective PUBLISH 8942@FOSDEM19@pentabarf.org 8942 ada_wrapup ada_wrapup Informal Discussions & Closing en en_US Ada 2019-02-02 18:50:00 +0100 2019-02-02 19:00:00 +0100 00:10:00:00 20190202T185000 20190202T190000 00:10:00:00 Informal Discussions & Closing <p>Informal discussion on ideas and proposals for future events.</p> PUBLIC CONFIRMED Ada https:/fosdem.org/2019/schedule/event/ada_wrapup/ AW1.125 Dirk Craeynest
