I want to learn Perl 6 myself, and I also want to create material that can be used to raise passion for the language when it's used as a first(ish) language. So I have convinced my daughters to create a study group where I will prepare materials and follow a project-based and design-thinking approach to learn Perl 6. My intention is also to find the way towards a more gender-balanced, inclusive community and test new ways of learning computer programs by eating my own dog food (as presented in other conferences).</p> <p>During the talk, which will be a dialogue, and maybe staged as a play, we will present our experience, what we have learned from it, what we haven't learned from it (hope Perl 6 is not in this category) and how others might benefit from it.

In particular for one of the core data categories in science and engineering, massive multi-dimensional arrays, out-of-memory solutions typically employ their own, different models.</p> <p>We discuss this situation on the example of the scalable open-source array engine, rasdaman ("raster data manager") which offers access to and processing of Petascale multi-dimensional arrays through an SQL-style array query language, rasql. Such queries are executed in the server on a storage engine utilizing adaptive array partitioning and based on a processing engine implementing a "tile streaming" paradigm to allow processing of arrays massively larger than server RAM. The rasdaman QL has acted as blueprint for forthcoming ISO Array SQL and the Open Geospatial Consortium (OGC) geo analytics language, Web Coverage Processing Service, adopted in 2008. Not surprisingly, rasdaman is OGC and INSPIRE Reference Implementation for their "Big Earth Data" standards suite.</p> <p>Recently, rasdaman has been augmented with a python interface which allows to transparently interact with the database (credits go to Siddharth Shukla's Master Thesis at Jacobs University). Programmers do not need to know the rasdaman query language, as the operators are silently transformed, through lazy evaluation, into queries. Arrays delivered are likewise automatically transformed into their python representation.</p> <p>The presenter is Principal Architect of rasdaman, editor of several "Big Data" standards, and co-chair of "Big Data" relevant working groups in several high-impact bodies. In the talk, the rasdaman concept will be illustrated with the help of large-scale real-life examples of operational satellite image and weather data services, and sample python code will be demonstrated live.</p> PUBLIC CONFIRMED Python https:/fosdem.org/2017/schedule/event/python_datacubes/ H.1308 (Rolin) Peter Baumann PUBLISH 5199@FOSDEM17@pentabarf.org 5199 graph_intro_graph_databases graph_intro_graph_databases Intro to Graph databases en en_US Graph 2017-02-04 10:30:00 +0100 2017-02-04 11:00:00 +0100 00:30:00:00 20170204T103000 20170204T110000 00:30:00:00 Intro to Graph databases <p>An introduction to graph databases.

New container technology like Singularity focuses on the portability of compute, allowing us to ease deployment, reducing administrative overhead and user support. However, some issues still need special attention, for example how to handle different MPI configurations (e.g. over Infiniband), and how to handle special resources like GPUs.</p> <p>Today, there is no need to have applications installed on any cluster or HPC/scientific resource; we can use container technology to encapsulate all the software and libraries of any specific application, ensuring the operation thereof in any possible operating system, software, and hardware architecture, avoiding  incompatibilities and retaining native or near-native performance. Our design strategy makes the container agnostic to the queue system i.e. the container works with SLURM, TORQUE and stand alone.</p> <p>This talk will cover creating such portable containers using multiple resources, and showing how simple is to deploy a complex MPI dependant application across multiple TOP500 supercomputer with only a regular user account, including the ability to exploit existing resources like Infiniband and GPGPUs.</p> <p>Also we’ll show how to add open source profiling tools to the container.

It remarkably raised testing versatility and provided a high flexibility to users and developers. But supporting the Genode API on self-contained third-party kernels is sometimes also accompanied with deficiencies, redundancies, or work-arounds. To also have the option of a basic kernel without such compromises, the custom Genode kernel was developed. Its main distinguishing mark may be that it not only trusts the Genode Core-component but even more is a mere library to it. The implications of this new design and other characteristics of the custom Genode kernel, such as scheduling, capabilities, and ARM virtualization, are discussed in this lecture.</p> PUBLIC CONFIRMED Microkernels and Component-based OS https:/fosdem.org/2017/schedule/event/microkernel_kernel_library/ AW1.125 Martin Stein PUBLISH 5591@FOSDEM17@pentabarf.org 5591 libreoffice_ui_concept libreoffice_ui_concept LibreOffice UI Concept A personal, user friendly and flexible interface en en_US Open Document Editors 2017-02-04 10:50:00 +0100 2017-02-04 11:10:00 +0100 00:20:00:00 20170204T105000 20170204T111000 00:20:00:00 LibreOffice UI Concept- A personal, user friendly and flexible interface <p>Starting from LibreOffice 5.3, LibreOffice user interface will be improved with the addition of a notebook bar which integrates with the existing layout.

With the assistance of the Flemish Inter-university Council (VLIR), lots of hard work and hardware donations by Ghent University they have succeeded in setting up a nation-spanning architecture comprised of three datacenters, in Havana (West), Santa Clara (central) and Santiago de Cuba (East). Their campuses are spread geographically across the 1000 km long island and are interconnected by a 20 Mbps network that covers up to the furthest regions of the island where remote rural universities are given the opportunity to take advantage of the magnificent capacities of massive parallel processing.</p> <p>Thus was born "HPC Cuba" the national center for academic supercomputing. While fully depending on Free Software for their operations, HPC Cuba has also joined the global Free Software community by producing installation packages for software not yet covered by EasyBuild.</p> <p>On a tropical island where access to resources is being limited by a US imposed trade embargo, setting up a datacenter capable of hosting a proper supercomputer "no es fácil" ("it is not easy", a Cuban saying).

From most perspectives, from Clang through to code generation, the size of most operations do not make much difference to the ease of implementation. However there are some assumptions that are baked deeply into the compiler; one of which is the memory access width, more specifically that it is addressible in 8-bit words. This however is not always the case, many embedded DSPs can only access memory with 16-bit addressibility, and trying to teach LLVM about this proves to be a challenge.</p> <p>In this talk, we will present our first explorations in this area, and share our thoughts on how we can make LLVM more memory agnostic for all targets with non-8-bit memory.</p> PUBLIC CONFIRMED LLVM Toolchain https:/fosdem.org/2017/schedule/event/llvm_16_bit/ K.3.201 Simon Cook PUBLISH 5352@FOSDEM17@pentabarf.org 5352 hpc_deployment_guix hpc_deployment_guix Optimized and reproducible HPC Software deployment with free software and GNU Guix en en_US HPC, Big Data and Data Science 2017-02-04 11:30:00 +0100 2017-02-04 11:55:00 +0100 00:25:00:00 20170204T113000 20170204T115500 00:25:00:00 Optimized and reproducible HPC Software deployment- with free software and GNU Guix <p>HPC computing environment and especially super computing has its bag of challenges when it comes to software deployment. As scientists we often do not get root access which means that we either depend on what software is available or we build software in a dedicated directory using tools such as Brew, Conda or even from source. Unfortunately these solutions depend on already installed tools from an underlying distribution, often proprietary or dated compilers, and, for example, modules. Any binary that gets produced, therefore, tends to be totally unique, both in the generated binary and its set of dependencies. This is bad, both for trouble shooting and for pursuing reproducible science. With GNU Guix we are developing a fully reproducible free software stack including all dependencies targeting cross-builds for heterogeneous computing environments, such as the Beacon Intel PHI-based supercomputer, without having a requirement for containers.

As your project grows, reality hits: some components or files may need to use different licenses than originally anticipated. There are many reasons why this can happen: you may need to interface with projects of another license, you may want to import code from other projects or your developers may not understand the subtleties of the licenses in use. Besides the obvious challenges of managing mixed license FOSS projects, such as license compatibility and tracking what licenses you use, you are running the risk of exposing your project to unintended consequences.</p> <p>This talk will explore unintended consequences, risks and best practices using some examples from the recent history of the Xen Project.

Given our current technology, that would be magic. The lack of wizarding skills did not stop us, however, from tackling the problem by using smart caching structures, which are witchcrafts on their own.</p> <p>Why is this challenge important? Several applications evaluate global queries on continuously changing graphs: <a href="https://neo4j.com/resources/recommendations-business-white-paper/">fraud detection in financial transactions</a>, <a href="http://docs.inf.mit.bme.hu/ingraph/pub/stein-daniel-static-analysis.pdf">analysis of source code repositories</a> and <a href="http://link.springer.com/chapter/10.1007/978-3-319-11653-2_40">validating engineering models</a>. Current approaches employ domain-specific optimizations, which are difficult and error-prone to implement. Meanwhile, the requirements of these (and similar) use cases could be uniformly addressed by incremental graph query evaluation. With this technique, the first execution of the queries takes some time, but once the result are calculated, they can be efficiently maintained for each change in the graph.</p> <p>To allow incremental queries on property graphs, we implemented the <a href="https://github.com/FTSRG/ingraph">ingraph</a> engine, based on the <a href="http://www.opencypher.org/">openCypher</a> language specification. We aim to support the <a href="https://github.com/opencypher/openCypher/blob/master/docs/standardisation-scope.adoc">standard subset</a> of openCypher, as most standard constructs can be calculated incrementally. We already mapped some of the standard constructs to <a href="http://docs.inf.mit.bme.hu/ingraph/pub/opencypher-report.pdf">relational algebra</a>, defined <a href="http://docs.inf.mit.bme.hu/preprints/perpol2016-gqo.pdf">incremental relational algebraic operators</a> and implemented them in an <a href="https://github.com/FTSRG/ire">incremental relational engine</a> using <a href="http://akka.io/">Akka</a> actors.</p> <p>We start the talk by presenting use cases that evaluate complex global queries on continuously changing graphs and discuss the idea of incremental graph queries. We show the mapping of basic openCypher constructs (e.g. <code>MATCH</code>, <code>WHERE</code>, <code>WITH</code>, <code>RETURN</code>) to relational operators, such as joins, selections and projections. Finally, we show our approach for optimizing incremental graph queries and outline related challenges.</p> <p>Target audience: Developers, looking for a deeper understanding of openCypher and/or facing complex queries on continuously changing graphs</p> PUBLIC CONFIRMED Graph https:/fosdem.org/2017/schedule/event/graph_incremental_queries_open_cypher/ H.2214 Gabor Szarnyas PUBLISH 5497@FOSDEM17@pentabarf.org 5497 libreoffice_interoperability_regression_testing libreoffice_interoperability_regression_testing Interoperability regression testing in LibreOffice en en_US Open Document Editors 2017-02-04 11:50:00 +0100 2017-02-04 12:10:00 +0100 00:20:00:00 20170204T115000 20170204T121000 00:20:00:00 Interoperability regression testing in LibreOffice PUBLIC CONFIRMED Open Document Editors https:/fosdem.org/2017/schedule/event/libreoffice_interoperability_regression_testing/ K.4.401 Xisco Fauli PUBLISH 5826@FOSDEM17@pentabarf.org 5826 community_strategy_for_developer_outreach community_strategy_for_developer_outreach CANCELLATION Strategy for developer outreach en en_US Community 2017-02-05 11:55:00 +0100 2017-02-05 12:30:00 +0100 00:35:00:00 20170205T115500 20170205T123000 00:35:00:00 CANCELLATION Strategy for developer outreach <ul> <li>We're sorry that this talk has been cancelled. *</li> </ul> <p>I look at how to create a developer outreach strategy that is suitable for community-led projects and commercially led products, including:</p> <ul> <li>setting goals</li> <li>creating programmes</li> <li>segmentation: who are you speaking to?</li> <li>choosing the right mix of activities</li> <li>content marketing measurement.</li> </ul> PUBLIC CONFIRMED Community https:/fosdem.org/2017/schedule/event/community_strategy_for_developer_outreach/ UD2.119 (Moved from AW1.124) Matthew Revell PUBLISH 5578@FOSDEM17@pentabarf.org 5578 desktops_zorin_desktop desktops_zorin_desktop The Linux Desktop for the Rest of Us The Past, Present and Future of Zorin OS and a Vision for the Linux Desktop en en_US Desktops 2017-02-05 11:55:00 +0100 2017-02-05 12:25:00 +0100 00:30:00:00 20170205T115500 20170205T122500 00:30:00:00 The Linux Desktop for the Rest of Us- The Past, Present and Future of Zorin OS and a Vision for the Linux Desktop <p>This talk will highlight the lessons learned from creating Zorin OS and the Zorin Desktop environment, how various optimisations have made our Linux desktop even more approachable and how the wider community can work together to spread the power of Linux to new classes of users around the world.</p> PUBLIC CONFIRMED Desktops https:/fosdem.org/2017/schedule/event/desktops_zorin_desktop/ K.4.401 Artyom Zorin PUBLISH 5139@FOSDEM17@pentabarf.org 5139 hdfsnvme hdfsnvme Evaluating NVMe drives for accelerating HBase NVM HBase acceleration en en_US Software Defined Storage 2017-02-05 12:00:00 +0100 2017-02-05 12:45:00 +0100 00:45:00:00 20170205T120000 20170205T124500 00:45:00:00 Evaluating NVMe drives for accelerating HBase- NVM HBase acceleration <p>Non-Volatile-Memory express (NVMe) standard promises and order of magnitude faster storage than regular SSDs, while at the same time being more economical than regular RAM on TB/$.

The introduction of Orchestration, SDN controllers, vSwitches and Virtual Dataplane have seen a huge change in how network packets are delivered to data-centre nodes. While the stacks that consume these packets, the socket based applications have evolved much more slowly. Virtual switches like VPP and OVS-DPDK, have benefited from the vector packet processing technology in DPDK to scale process millions of packets per second, while TCP and UDP socket based applications have not yet benefited.

It has served HPC support teams well on standard Linux/x86 systems since 2012.</p> <p>More recently, interest has grown to also employ EasyBuild on Cray systems, where the Cray Programming Environment (PE) not only provides common tools (compilers, ...) and libraries (MPI, BLAS/LAPACK, FFTW, ...), but also tuned installations of 3rd party libraries like HDF5, netCDF and PETSc. The Cray PE consists of an extensive stack of environment modules, providing a familiar yet complex working environment of users.</p> <p>To leverage the Cray PE a couple of enhancements had to be made to EasyBuild, including support for using 'external' modules, and defining Cray-specific compiler toolchains. In addition, the way in which EasyBuild deals with environment modules had to be carefully revisited, since standard operations like 'module purge' are not supported by the Cray PE.</p> <p>This work has led to the use of EasyBuild in production on the largest Cray supercomputer in Europe, the Piz Daint system at the Swiss National Supercomputing Centre.</p> <p>In this talk, we will outline how Cray systems are different from standard HPC systems, motivate the need for a tool like EasyBuild despite the presence of Cray PE, and show how EasyBuild was tweaked to support reproducible software installations on Cray systems.</p> <p>We believe this is interesting success story of how FOSS has significantly enhanced the software environment on a multi-million dollar production system.</p> PUBLIC CONFIRMED HPC, Big Data and Data Science https:/fosdem.org/2017/schedule/event/cray_easybuild/ H.2213 Guilherme Peretti-Pezzi PUBLISH 5446@FOSDEM17@pentabarf.org 5446 digital_hw_sw_lessons digital_hw_sw_lessons Digital hardware design What can we learn from software development – and what not? en en_US Electronic Design Automation (EDA) 2017-02-05 12:00:00 +0100 2017-02-05 12:25:00 +0100 00:25:00:00 20170205T120000 20170205T122500 00:25:00:00 Digital hardware design- What can we learn from software development – and what not? <p>Traditionally, the goal of digital hardware design has been to produce an ASIC.

These operations create or remove volumes, copy data between volumes, create or merge snapshots, and various other actions related to virtual machine storage. For efficiency and balance these operations should be distributed across multiple hosts and run in parallel when possible. Maintaining reliability under real world conditions requires careful management and resilient algorithms. This talk will introduce some of the problems that can arise including: dropped communications, scheduling conflicts, and host or storage array failure. Next, a solution to these problems using shared storage locking, atomic operations, volume generations, and forensic analysis of the storage will be presented. Through step by step examples, the audience will understand how the proposed solution can solve all of the outlined problems.</p> PUBLIC CONFIRMED Virtualisation and IaaS https:/fosdem.org/2017/schedule/event/iaas_nexgencer/ UB2.252A (Lameere) Adam Litke PUBLISH 4662@FOSDEM17@pentabarf.org 4662 lorawan lorawan LoRaWAN for exploring the Internet of Things Talk Hard: A technical, political, and cultural look at LoRaWAN for IoT en en_US Miscellaneous 2017-02-04 12:00:00 +0100 2017-02-04 12:50:00 +0100 00:50:00:00 20170204T120000 20170204T125000 00:50:00:00 LoRaWAN for exploring the Internet of Things - Talk Hard: A technical, political, and cultural look at LoRaWAN for IoT <p>Everyone is excited about the The Internet of Things (IoT) and the possibilities of really seeing the democratization of the internet, devices for everyone needs, not just a few!

This makes tracking the applications and libraries that actually get used considerably more important. Existing solutions (module load hooks, launch wrappers) do not account for user-built software, are hard to deploy or produce inconclusive results.</p> <p>OGRT enables the tracking of jobs on a cluster with process-level granularity and without discernible performance penalty. It tracks used shared libraries, environment variables and loaded modules at the moment of process execution. It also supports watermarking executables and shared objects and reading those watermarks out of memory at runtime. Gathered information is collected and shipped to various backends.</p> <p>OGRT aims to be a versatile tool, which can be used to:</p> <ul> <li>provide a census of used software (including user-built)</li> <li>troubleshoot problems with programs picking up unexpected shared libraries</li> <li>retroactively inform users about buggy libraries</li> <li>overlay process-level data onto existing job monitoring tools</li> <li>contribute to reproducibility of application runs</li> </ul> <p>This presentation will give an overview of the design and implementation of OGRT, as well as demoing some of its capabilities when plugged into an Elasticsearch backend.</p> PUBLIC CONFIRMED HPC, Big Data and Data Science https:/fosdem.org/2017/schedule/event/ogrt/ H.2213 Georg Rath PUBLISH 5560@FOSDEM17@pentabarf.org 5560 libreoffice_xml libreoffice_xml LibreOffice XML Help in your local browser Bringing 2017 to LibreOffice Help en en_US Open Document Editors 2017-02-04 12:30:00 +0100 2017-02-04 12:50:00 +0100 00:20:00:00 20170204T123000 20170204T125000 00:20:00:00 LibreOffice XML Help in your local browser- Bringing 2017 to LibreOffice Help <p>Currently the LibreOffice help system is based on a technology developed circa 2005, and uses the internal Writer - Web module to display its contents.

Available metrics range from raw CPU and memory usage to operation of the Garbage Collector and JIT compiler through to thread activity and method call/heap profiles. Thermostat provides a GUI view of activity of local and distributed JVMs in a live-view or, alternatively, offline for after-the-fact analysis.</p> <p>What Thermostat cannot do on its own is track events and record statistics that are specific to a given Java application, at least not unless the application co-operates with it, for example by publishing JMX statistics that Thermostat can read, persist and display in its GUI. However, that's about to change thanks to work Thermostat developers have been doing to integrate Byteman into Thermostat.</p> <p>Byteman is a tool which can be used to modify the behaviour of Java programs by injecting extra Java code almost anywhere in the program. You don't need to recompile your program or even prepare it in advance in order for this to work. You can specify changes to the program on the command line but, what is more amazing, you can actually use Byteman to change the way a program runs after startup while it is still running.</p> <p>In this talk we will show how Thermostat can collect and visualize metrics with Byteman's help in order to better understand a specific performance issue in a Java application.</p> PUBLIC CONFIRMED Free Java https:/fosdem.org/2017/schedule/event/thermostat/ H.1302 (Depage) Severin Gehwolf PUBLISH 5096@FOSDEM17@pentabarf.org 5096 jitsi jitsi Jitsi: state of the union What's new in Jitsi and its related projects en en_US Real Time Communications 2017-02-04 12:35:00 +0100 2017-02-04 12:55:00 +0100 00:20:00:00 20170204T123500 20170204T125500 00:20:00:00 Jitsi: state of the union- What's new in Jitsi and its related projects <p>Jitsi offers seamless and secure multiparty video conferencing while being 100% Open Source.

The loss of a single node or a dozen hard drives is automatically handled by the systems running a datacenter, removing the need to page someone at 4am. This calls for an alerting system that understands service availability at a global scope, yet is still able to give detailed reports if and when there is a service-impacting incident. Prometheus achieves this by defining alerting conditions directly on time series data. The resulting alerts are grouped and aggregated into comprehensive and meaningful notifications.

The SPARK language also provides specification features, so that the intended behavior of the program can be embedded in the program itself. The SPARK formal verification tool can check that a program does not contain any run-time error, such as buffer or integer overflows, and that the code complies with its specification. We will demonstrate these capabilities on a game of Tetris, whose core game logic has been proved, and which has been ported to several embedded platforms: SAM4S Xplained Pro Evaluation Kit, Pebble Time watch, Unity game engine, Arduboy game platform.

This talk will provide an overview of the (often legal) control points that exist in open communities, and various strategies used by corporations to seize them.

One rightfully popular approach is to run the application as a Docker container inside a Kubernetes cluster, giving you a lot of operational benefits thanks to the Kubernetes folks.</p> <p>For the most part it is rather easy to make your Python application work inside a Docker container. But there are a number of common patterns one can follow to save time by delegating more things to the runtime environment. Furthermore you can start adding a few simple non-intrusive features to your application which will help improve the application live-cycle in the cluster, ensuring smooth hand-over when migrating the container to different nodes or scaling it up or down.</p> <p>This talk will discuss how to write a Python application which will behave well in this environment, starting with the basics steps you can rely on the runtime for, covering logging and all the way to supporting the service life-cycle, health checking and monitoring in a Kubernetes environment. You will see that building a cloud-native application is not very hard and something you can gradually introduce.</p> PUBLIC CONFIRMED Python https:/fosdem.org/2017/schedule/event/cloud_native_python/ UD2.120 (Chavanne) Floris Bruynooghe PUBLISH 4995@FOSDEM17@pentabarf.org 4995 ogd_includo ogd_includo Can open source open minds?

Often, data get discretized in space and time, nat­ur­ally leading to multi-dimensional arrays. In fact, arrays play a core role in most domains of science, engineering, and bus­in­ess - generally speak­ing, spatio-temporal sensor, image, time­series, sim­­ul­ation, and statistics data­. This raises the need for flexible, scalable, and open services in replacement of the bespoke silo solutions that have prevailed in the past.</p> <p>Traditional databases have been successful due to their flexibility (through query languages) and scalability (through manifold optimizations and parallelization in the server) - however, they unfortunately do not support massive arrays. This is being remedied within ISO currently where SQL/MDA ("Multi-Dimensional Arrays") is in an advanced stage, likely becoming adopted in summer 2017. SQL/MDA adds declarative array definition and operations to SQL. Not only paves this the way for powerful services, maybe even more important it allows, for the first time, integrating data and metadata into the same archive, even in one and the same query. As such, SQL/MDA will be a game changer in data services not only for science and engineering at large.</p> <p>We present the concepts and rationales, as well as the open-source technology rasdaman ("raster data manager") which is serving as the blueprint for MDA.</p> PUBLIC CONFIRMED Miscellaneous https:/fosdem.org/2017/schedule/event/datacubes/ K.1.105 (La Fontaine) Peter Baumann PUBLISH 5275@FOSDEM17@pentabarf.org 5275 virtuozzo_containers virtuozzo_containers Virtuozzo containers, how it works virtuozzo, most known as openvz containers techonlogy en en_US Lightning Talks 2017-02-04 13:00:00 +0100 2017-02-04 13:15:00 +0100 00:15:00:00 20170204T130000 20170204T131500 00:15:00:00 Virtuozzo containers, how it works- virtuozzo, most known as openvz containers techonlogy <p>openvz containers, how it works and how it looks</p> PUBLIC CONFIRMED Lightning Talks https:/fosdem.org/2017/schedule/event/virtuozzo_containers/ H.2215 (Ferrer) Alexander Stefanov PUBLISH 5493@FOSDEM17@pentabarf.org 5493 clang_formal_verification_tool_frontend clang_formal_verification_tool_frontend Using clang as a Frontend on a Formal Verification Tool en en_US LLVM Toolchain 2017-02-05 13:00:00 +0100 2017-02-05 13:40:00 +0100 00:40:00:00 20170205T130000 20170205T134000 00:40:00:00 Using clang as a Frontend on a Formal Verification Tool <p>ESBMC is a SMT-based context-bounded bounded model checker that aims to provide bit-precise verification of both ANSI-C and C++ programs.

With Singularity, HPC users can safely bring their own execution environments to the cluster. Unlike other container solutions, Singularity does not require root level permissions to run containers, which allows users to freely control what software stack they wish to use. Provisioning of a container image can be done locally on the user's machine or on Singularity Hub. The resulting image can then be securely executed on any machine with Singularity installed. Reproduction of results has never been easier: a user can now share a single Singularity image file that will ensure a consistent execution environment wherever it is run.</p> <p>This presentation will provide an in-depth look at how Singularity is able to securely run user containers on HPC systems. After a brief introduction to Singularity and its relationship to other container solutions, the details of Singularity's runtime will be explored. The way that Singularity leverages Linux features such as namespaces, bind mounts, and SUID binaries will be discussed in further detail as well.</p> PUBLIC CONFIRMED Linux Containers and Microservices https:/fosdem.org/2017/schedule/event/singularityhpc/ UA2.220 (Guillissen) Michael Bauer PUBLISH 5913@FOSDEM17@pentabarf.org 5913 go_lighting_talks go_lighting_talks AMENDMENT Go lighting talks Lighting talks about Go en en_US Go 2017-02-05 13:25:00 +0100 2017-02-05 13:55:00 +0100 00:30:00:00 20170205T132500 20170205T135500 00:30:00:00 AMENDMENT Go lighting talks- Lighting talks about Go <p>Go lightning talks.

The idea is to ease the use of well-known and established end-to-end cryptographic tools for already existing and widely used written digital communication channels, starting with email and radically easing adoption of OpenPGP-compliant encryption for it. Later on, XMPP-based communication channels (using e.g. OTR) and others will be added, with the ultimate goal to route all messages through GNUnet, a secure peer-to-peer framework, which doest not just protect message contents, but also metadata.</p> <p>Basically, p≡p's proposed and (to some degree) already implemented protocols automate the steps taught to users at CryptoPartys, from which the project emerged.</p> <p>p≡p supports multiple platforms (e.g., Android, *BSDs, GNU/Linux distributions, iOS, MacOS X and Windows), multiple programming languages and environments (e.g., C#/COM, C++/Qt, Java, JavaScript, Objective-C/Swift and Python) and will provide easy access to multiple crypto technologies through an abstract API which doesn't require application developers to have in-depth cryptographic knowledge, i.e. the p≡p engine takes care of the details. The focus for now is to have OpenPGP-compatible communications for email widespread, using already existing crypto tools like GnuPG and a NetPGP fork (needed for iOS).</p> <p>p≡p's core parts (the p≡p engine and the adapters / bindings for different programming languages) are owned by the Swiss-based, tax-free p≡p foundation and held under the GNU GPL v3 license alongside with the p≡p trademarks. The foundation is run by privacy activists from Germany and Switzerland. Any project willing to implement p≡p will be supported, especially in the Free Software world. For trust and security reasons, the p≡p foundation requires projects to let their p≡p implementations code audited by a trustworthy independent firm upon every release, if they want to use the p≡p trademarks, so as to make sure there are no backdoors in officially endorsed p≡p end-user software. The p≡p foundation, for cases where the money for such undertakings is not available, is willing to either finance the code audits itself or to organize such funding at least.</p> <p>p≡p foundation has close cooperations with the Enigmail (Enigmail 2.0 will be Enigmail/p≡p), the GNUnet project and soon ISOC Switzerland (ISOC-CH).</p> <p>But there's also extensive exchange with other groups like the CCC (particularly in Switzerland), the FSFE, the Mozilla Foundation (Mozilla Thunderbird in particular), The Reva &amp; David Logan Foundation and the GnuPG project.</p> <p>The Lightning Talk will be quite short: 10mins. 5mins will be reserved for (hopefully) lots of questions. :) (For further and more detailled questions, just visit us at the GNU Taler / p≡p foundation stand in building K, level 1, group A.)</p> <p>The speaker, Hernâni Marques, is council member of the p≡p foundation.</p> <p>(Note that this talk was originally going to be presented by Volker Birk, p≡p foundation's council president, who now cannot be present.)</p> PUBLIC CONFIRMED Lightning Talks https:/fosdem.org/2017/schedule/event/pep/ H.2215 (Ferrer) Hernâni Marques PUBLISH 5161@FOSDEM17@pentabarf.org 5161 ruby_jruby_in_2017_rails5_ruby24_performance ruby_jruby_in_2017_rails5_ruby24_performance JRuby in 2017: Rails 5, Ruby 2.4, Performance We'll survey the work going on to make JRuby more compatible and faster in 2017 en en_US Ruby 2017-02-04 13:45:00 +0100 2017-02-04 14:35:00 +0100 00:50:00:00 20170204T134500 20170204T143500 00:50:00:00 JRuby in 2017: Rails 5, Ruby 2.4, Performance- We'll survey the work going on to make JRuby more compatible and faster in 2017 <p>JRuby has been compatible with various Ruby versions during its lifespan, ranging from the 1.6 series through today's 2.4.

It automates any application, interacting with GUIs exactly as a human would do. In this way, Alyvix can check the availability and can measure the responsiveness of applications. From a computer science point of view, Alyvix is an open-source Python-based software, which can be deployed on Windows 64-bit machines as a part of an open-stack of libraries. Alyvix mainly relies on the following open-source software projects: RobotFramework for desktop automation, OpenCV and Pillow for image processing, TesseractOCR for text recognition and PyQt for GUI programming. Francesco Melchiori, as Alyvix product manager, will explain how Alyvix works leveraging on the aforementioned packages, what software design choices have been taken. Finally, he will show how this computer vision solution solves the need of an effective visual synthetic monitoring of proprietary network applications.

Using libertine allows us to use everyday applications which have not been ported over to a new packaging format or don't work natively with a new display server. Libertine has allowed us to take advantage of classic apps such as Firefox and LibreOffice in Ubuntu Touch, a version of Ubuntu for devices based on click packaging and Mir/Unity8. Ubuntu developers have recently unveiled snappy, a new kind of packaging system which keeps an application confined to a readonly filesystem with all of its dependencies managed internally. Since migrating applications to snaps is a manual process, we've been working on a libertine snap to give us the ability to use non-snap applications in an all-snaps Ubuntu.</p> <p>This lecture will start with an overview of why libertine is a necessary component for managing and launching deb-based applications on both a classic Mir/Unity8 system and a completely confined all-snaps Ubuntu. Then there will be a review of how libertine works in general through container management and application launching. Finally, these topics will come together with an explanation of the infrastructure required for libertine to operate in an all-snaps environment.

More importantly GC saves the programmer from having to debug their mistakes when using malloc and free. Unfortunately the details of how GC works are often a black box. This talk will start with a tour of all of the GC algorithms currently available in OpenJDK. We'll discuss how they work, their strengths and weaknesses, and which class of applications they were developed for. We'll work our way through serial gc, parallel gc, concurrent mark and sweep, and g1. We'll make the case for why we need all of them and just one more GC algorithm, Shenandoah.</p> <p>Shenandoah is a parallel and concurrent GC algorithm designed for applications with 100gb+ heaps and tight pause time constraints. It's the first GC algorithm targeting OpenJDK which compacts the live objects while the Java threads are running. We'll describe the algorithm itself, the implementation details, and the optimizations needed to achieve good performance.

In an attempt to bring back some of the dataplane logic from the controller to the programmable switches, the <a href="https://beba-eu.github.io/">OpenState</a> abstraction layer has been designed, to enable efficient stateful packet processing through programmable actions occurring at the switch level.</p> <p>The first part of this talk in an introduction to OpenState and includes a description of the layer as well as some example use cases.

One of the most exciting recent crypto-networking developments, WireGuard aims to drastically simplify secure tunneling. The current state of VPN protocols is not pretty, with popular options, such as IPsec and OpenVPN, being overwhelmingly complex, with large attack surfaces, using mostly cryptographic designs from the 90s. WireGuard presents a new abuse-resistant and high-performance alternative based on modern cryptography, with a focus on implementation and usability simplicity. It uses a 1-RTT handshake, based on NoiseIK, to provide perfect forward secrecy, identity hiding, and resistance to key-compromise impersonation attacks, among other important security properties, as well as high performance transport using ChaCha20Poly1305. A novel IP-binding cookie MAC mechanism is used to prevent against several forms of common denial-of-service attacks, both against the client and server, improving greatly on those of DTLS and IKEv2. Key distribution is handled out-of-band with extremely short Curve25519 points, which can be passed around in the likes of OpenSSH. Discarding the academic layering perfection of IPsec, WireGuard introduces the idea of a "cryptokey routing table", alongside an extremely simple and fully defined timer-state mechanism, to allow for easy and minimal configuration; WireGuard is actually securely deployable in practical settings. In order to rival the performance of IPsec, WireGuard is implemented inside the Linux kernel, but unlike IPsec, it is implemented in less than 4,000 lines of code, making the implementation manageably auditable. These features converge to create an open source VPN utility that is exceedingly simple, yet thoroughly modern and secure.</p> PUBLIC CONFIRMED Security and Encryption https:/fosdem.org/2017/schedule/event/wireguard/ Janson Jason A.

Numerous techniques and metrics were developed. However, there is still a need in an approach that can both assert program domain and provide some reliable metrics. And such approach exists. It is called Mutation Testing. Here is a brief overview:</p> <p>There is a function and a test for that function. Any semantic change in the function (so called 'mutant') should break the test ('kill mutant'). If that's not the case, then mutant is considered as survived. No mutants should survive ever. If they are, then either the test is bad or the function is not correct.</p> <p>Research in this area exists since 70's. However, this approach is not widely adopted. The computational cost is one of the blockers. Another one, is the way such systems are implemented: most of them do mutations at the AST level, hence they are tightly coupled to the particular languages.</p> <p>We want to present you Mull: our implementation of Mutation Testing system. We use JIT and runtime compilation to speedup the system and make it accessible for everyday usage. Besides that we go down to the IR level, making the system applicable for any LLVM-based language such as C, C++, Rust, Objective-C, and many others.</p> <ul> <li>https://github.com/mull-project/mull</li> </ul> PUBLIC CONFIRMED LLVM Toolchain https:/fosdem.org/2017/schedule/event/mutation_testing/ K.3.201 Alex Denisov PUBLISH 5112@FOSDEM17@pentabarf.org 5112 odl_intro odl_intro Getting Started with OpenDaylight en en_US SDN and NFV 2017-02-04 14:30:00 +0100 2017-02-04 15:00:00 +0100 00:30:00:00 20170204T143000 20170204T150000 00:30:00:00 Getting Started with OpenDaylight <p>Heard about OpenDaylight and SDN?

A very simple observation has led to an optimisation in the way helgrind captures stack traces for its 'full recording' of where a piece of memory was modified.

We will describe the issues encountered during the implementation and discuss the reasons why this optimisation is not (yet?) committed in the Valgrind sources.</p> <p>The second optimisation is the implementation of the execution tree concept : this generalises the way Massif (a heap profiler) records the memory usage of a program.

By avoiding existing patents, interesting new techniques for efficient audio compression were invented. Now, in the effort to make a royalty free video codec in the same spirit as Opus, even more companies have joined into the "Alliance for Open Media" organization, with its first codec titled "AV1". Starting from the codebase of Google's VP9 codec, AV1 has currently over 45 experimental coding tools contributed by its member companies with the hopes that many will make it into the final version of the codec.

On Software Defined Radio (SDR) platforms, separating the channels can prove more difficult though due to high requirements for the digital filters. This talk will showcase an implementation of a polyphase filterbank on a graphics processor unit (GPU) that can help overcome the heavy computational load of those filters. In the software, all the partitioned filters can run in parallel. Each of these filters produces output samples for numerous input samples simultaneously, thus providing an additional parallel approach. Furthermore, several rational oversampling factors are supported by this implementation. Operations for oversampling can as well be implemented to run in parallel, due to the massive amount of usable hardware threads in a GPU. Hence, the effects of oversampling on the throughput can be reduced. On an Nvidia GTX970 GPU, this implementation achieved a throughput of 67.43 MSamples per second, 12 times higher than the (optimized) general purpose processor (GPP) version.</p> PUBLIC CONFIRMED Software Defined Radio https:/fosdem.org/2017/schedule/event/gpupfb/ AW1.120 Jan Kraemer PUBLISH 5753@FOSDEM17@pentabarf.org 5753 ruby_what_makes_jruby_and_truffle_run_optcarrot_9_times_faster_than_mri ruby_what_makes_jruby_and_truffle_run_optcarrot_9_times_faster_than_mri What makes TruffleRuby run Optcarrot 9 times faster than MRI? en en_US Ruby 2017-02-04 14:45:00 +0100 2017-02-04 15:35:00 +0100 00:50:00:00 20170204T144500 20170204T153500 00:50:00:00 What makes TruffleRuby run Optcarrot 9 times faster than MRI? <p>TruffleRuby runs Optcarrot 9 times faster than MRI 2.</p> <p>TruffleRuby is new optimizing implementation of Ruby.

Bespoke database software seems to crop up daily in the name of performance or functionality. This talk will examine the ever growing field of monitoring systems and their respective databases, and look in depth as to how Postgres can be used in a number of these places. Systems of this nature are typically tasked with collecting and storing metrics from your infrastructure, drawing pretty graphs, and nagging you when things break.</p> <p>Forms of data stored by these systems are nothing to be afraid of - they often include: - Time series metrics - the history of a measurement over time, e.g. temperatures - Logs - unstructured text emitted by applications, operating systems and hardware - Events - schema-less but well structured notifications</p> <p>An assertion of this talk is that for a majority of use cases, Postgres is more than capable of storing all of this data. We will attempt to replace numerous well known pieces of software with just one Postgres database. Of course we are told to use the right tool for the job, but having to learn and operate a single tool is a huge operational advantage.</p> <p>We’ll get quite technical in this talk, take a look the data models and access patterns required, and how this can be fitted into the general purpose environment of Postgres. Additionally, it is always constructive to look at what can be problematic, and not just focus on the positives, and why many turn to other bespoke solutions.</p> PUBLIC CONFIRMED PostgreSQL https:/fosdem.org/2017/schedule/event/postgresql_infrastructure_monitoring/ H.1309 (Van Rijn) Steven Simpson PUBLISH 5133@FOSDEM17@pentabarf.org 5133 odl_bgp odl_bgp Open-Source BGP networking with OpenDaylight using OpenDaylight to enable advanced BGP use-cases en en_US SDN and NFV 2017-02-04 15:00:00 +0100 2017-02-04 15:30:00 +0100 00:30:00:00 20170204T150000 20170204T153000 00:30:00:00 Open-Source BGP networking with OpenDaylight- using OpenDaylight to enable advanced BGP use-cases <p>In this talk I will give a short overview of how OpenDaylight can be used to enable a range of advanced BGP use-cases - such as traffic optimisation and DDoS mitigation.

Some day, when a pair of them was placed close to our home, I set off to explore how they are working. In this talk, I will describe how I used a cheap RTL-SDR together with GQRX, Inspectrum, and GNU Radio to reverse engineer the modulation and frame format of different types of wireless traffic lights. With some patience, I could also make some sense out of the bits. In particular, I was able to extract the signal state and display it in a web interface, mirroring the traffic light.

Our example use case integrates reconfigurable hardware accelerators into the Crypto API. We apply a new, declarative and device-tree-driven reconfiguration framework within the Linux kernel as proposed and implemented by Alan Tull. The implemented concept maps reconfigurable regions within the FPGA to device tree nodes. The insertion of a device tree overlay triggers the reconfiguration of the corresponding reconfigurable region. The reconfiguration process consists of the scheduling, descheduling and execution phase. Based on our usecase, benchmark results for the scheduling phases are shared. We present the bottlenecks revealed by our benchmark and show currently missing components of this approach. We conclude that the current implementation is already in a usable state for developing and deploying MPSoC-FPGA based heterogeneous systems.</p> PUBLIC CONFIRMED Lightning Talks https:/fosdem.org/2017/schedule/event/programming_reconfigurable_devs/ H.2215 (Ferrer) Ulrich Langenbach PUBLISH 4921@FOSDEM17@pentabarf.org 4921 troubleshootkube troubleshootkube Troubleshooting Kubernetes en en_US Linux Containers and Microservices 2017-02-05 15:20:00 +0100 2017-02-05 16:05:00 +0100 00:45:00:00 20170205T152000 20170205T160500 00:45:00:00 Troubleshooting Kubernetes <p>Kubernetes is a tremendous system for orchestrating your containers onto physical infrastructure.

It unpicks blocks of machine code, hands them off to the tool for instrumentation, recompiles the result, and links the instrumented version into the running image. By using a target independent intermediate representation, it insulates tools from the complexity of the underlying instruction sets.</p> <p>Back in 2003, when the framework was designed, I never dreamt that it would end up supporting X86, ARM, POWER, MIPS, S390 and TILEGX in both 32- and 64-bit variants. From that perspective VEX has been amazingly successful. But the framework is now showing its age. Recent instruction set features (transactional memory, LoadLinked/StoreConditional, wide vectors) have proven difficult to implement. It supports precise memory exceptions only poorly. And perhaps worst, its simplistic compilation pipeline causes it to generate code that is uncompetitive compared to other frameworks, particularly DynamoRIO and PIN.</p> <p>In this talk I'll outline VEX's structure, then talk about these problems and what can be done about them. And I'd be particularly interested to hear opinions on how much effort, and for which problem areas, should be invested in upgrading it.</p> <p>For the audience, some background in compiler internals and assembly code programming would be helpful, but is not essential.</p> PUBLIC CONFIRMED Valgrind https:/fosdem.org/2017/schedule/event/valgrind_vex_future/ UD2.119 (Moved from AW1.124) Julian Seward PUBLISH 5563@FOSDEM17@pentabarf.org 5563 geli_boot geli_boot GELIBoot Booting FreeBSD from encrypted disk en en_US BSD 2017-02-04 15:30:00 +0100 2017-02-04 16:25:00 +0100 00:55:00:00 20170204T153000 20170204T162500 00:55:00:00 GELIBoot- Booting FreeBSD from encrypted disk <p>FreeBSD has supported disk encryption with GBDE and GELI since 2002 and 2005 respectively. However, booting the system required storing the loader and kernel unencrypted so that the requisite GEOM module could be loaded to handle decryption. This became a significantly larger stumbling block with the introduction of ZFS, as having multiple separate partitions detracts from the advantages of ZFS, and also causes headaches when upgrading the operating system. With the growing popularity of ZFS Boot Environments, a solution was needed that allowed the kernel and loader to remain part of the primary file system, even if it was encrypted.

A useful abstraction for spatio-temporal raster data (and beyond) is the coverage data model, as standardized by ISO, OGC, and INSPIRE. Rather than zillions of individual image files it provides spatio-temporal "datacubes" for simple, efficient handling through the corresponding service model, the Web Coverage Service (WCS) with its Web Coverage Processing Service (WCPS) geo analytics language - "one cube tells more than a million images".</p> <p>Open-source rasdaman ("raster data manager") is the official reference implementation of both OGC and INSPIRE WCS. It supports easy incremental construction and maintenance of spatio-temporal datacubes, based on the OGC WCS-T standard. Retrieval may use WMS for visual navigation, WCS for data extraction and download, and WCPS for massive server-side processing. On server side, adaptive data partitioning and "tile streaming" processing enables fast query responses. In July 2016, US magazine CIO Review has included rasdaman in its top 100 Big Data technologies list.</p> <p>In this talk we present coverages in terms of concepts, implementation, and large-scale application. Live demos underpin the talk, using publicly accessible sites where the audience can replay and modify the examples. Being editor of the OGC and ISO coverage standard the presenter can give first-hands insights and answers, such as about the new generalized grid model for coverages (CIS 1.1) which OGC has adopted in Fall 2016 as well as the newly adopted INSPIRE-WCS.

MiNiFi is a lightweight application which can be deployed on hardware orders of magnitude smaller and less powerful than the existing standard data collection platforms. With both a JVM compatible and native agent, MiNiFi allows data collection in brand new environments — sensors with tiny footprints, distributed systems with intermittent or restricted bandwidth, and even disposable or ephemeral hardware. Not only can this data be prioritized and have some initial analysis performed at the edge, it can be encrypted and secured immediately. Local governance and regulatory policies can be applied across geopolitical boundaries to conform with legal requirements.

End users of consumer devices aim to have an instant gratification which is based on data/metrics produced by the object. At the end, IoT makers have to execute an epic split: Build the actual device (mechanical and electronics), Be over the top in firmware development in order to be secured Design services based on the object data. Surrounding all that is a hard job for a product team. In such a context Open Source Software constitutes basic building blocks of IoT devices. Data produced by smart devices are often time series, storing them is not the challenge, many good open source solutions exists (OpenTSDB, Influx..) but developing algorithms based on your data is difficult. It can become a nightmare if you have to think about scalability. Warp10 is a 3 years old open source platform designed for collect, store and manipulate sensor data with WarpScript, a language dedicated to time series analysis. WarpScript works natively on times series stored into Warp 10 (based on either levelDB or HBase) but can be connected to any data source. When you manipulate sensor data, you must deal with privacy. Security and privacy have also been addressed by Warp 10 since its very inception, this includes fine grain access control mechanisms, encryption capabilities and throttling management. Warp10 plateform can be integrated into an open ecosystem likes Storm, Flink, or also Apache Pig with one cornerstone, the capatibility of manipulate time series with WarpScript.</p> PUBLIC CONFIRMED Internet of Things https:/fosdem.org/2017/schedule/event/iot_warp10/ AW1.126 Sébastien Lambour PUBLISH 5409@FOSDEM17@pentabarf.org 5409 python_prompt_toolkit python_prompt_toolkit prompt_toolkit two years later en en_US Python 2017-02-05 15:30:00 +0100 2017-02-05 16:00:00 +0100 00:30:00:00 20170205T153000 20170205T160000 00:30:00:00 prompt_toolkit- two years later <p>Two years ago at Fosdem 2015, I presented prompt_toolkit, a library for building command line applications.

We all love food. We want the recipe app to be community driven. GNOME people all over the world will be entering their favourite recipes and also they will be able to cook delicious things using the GNOME recipes.</p> <p>This is not a new idea. Looking all the way back to 2007, the idea of a GNOME cook book was already around (https://wiki.gnome.org/GnomeCookbook). For one reason or another, we never quite got there. But the idea has stuck around. With the upcoming 20th birthday of GNOME next year, we thought that we should make another attempt at this app, maybe as a birthday gift to all of us. Once we release the app, we will start to collect the content and print as a cookbook.</p> <p>My talk will be shortly about how we decided to build the GNOME Recipe App as a community, how i started to work on mock-ups, how Jakub Steiner (design) designed them based on my mock-ups and how Matthias Clasen (engineering) implemented them.</p> <p>My real motivation with this talk to explain how we had fun while working on the app and encourage designers to contribute open source projects more.</p> <p>You can see the demo video and landing page design on the files screen.

It serves as the basis of the NixOS Linux distribution (that can be automatically installed from a single declarative specification), as well as a number of additional deployment solutions, such as NixOps, that deploys virtual machines in the cloud and Hydra: the Nix-based continuous integration server. Although Nix offers all kinds of deployment benefits, integration with language-specific package managers that also do dependency management, such as the NPM package manager, is problematic as they conflict with Nix's reliability properties. In this presentation, I will show <code>node2nix</code>, a tool that automatically generates Nix expressions (build recipes) from an NPM package's <code>package.json</code> configuration file, allowing users to deploy NPM packages with the Nix package manger alongside other types of packages (e.g. Autotools, Perl, Python, ...) that constitute a large complex system.</p> PUBLIC CONFIRMED Distributions https:/fosdem.org/2017/schedule/event/deploying_npm_packages_with_nix/ K.4.601 Sander van der Burg PUBLISH 5221@FOSDEM17@pentabarf.org 5221 transport_evolution_bsd transport_evolution_bsd Transport Evolution on top of the BSD's A New, Evolutive API and Transport-Layer Architecture for the Internet en en_US BSD 2017-02-04 16:30:00 +0100 2017-02-04 17:25:00 +0100 00:55:00:00 20170204T163000 20170204T172500 00:55:00:00 Transport Evolution on top of the BSD's- A New, Evolutive API and Transport-Layer Architecture for the Internet <p>Internet Transport is changing, some changes have been incremental updates to mechanisms (e.g., RACK, BBR), others demand new protocol options (e.g., MPTCP) or entirely new protocols (e.g., QUIC, SCTP). However significant changes are still difficult to deploy - requiring modifications to application code and support by the stack. Even when updates happen, the network needs to support the new method to allow applications to use it. Long deployment times have motivated the need to change how protocols are handled in the stack. We review the state of the art in Internet Transport, and the status of deployment in th BSD's and then propose a new direction for the transport interface, developed in the EU NEAT Project, that can ease deployment of new transports across all platforms.

Although many features like the famous sun.misc.Unsafe are now provided by other public APIs, there is still the problem of making your code work with previous Java versions, but also dynamically using the new Java 9 replacements. Apache Lucene, the open source fulltext search library behind Apache Solr and Elasticsearch, is also using some of those "hacks" to work around issues in the Java API, but the developers also noticed that some code in the project hit some limits introduced by the module system. This talk will show on some examples how Apache Lucene managed to allow its code to run with different java versions (without using multi-release JAR files, as this brings additional burden with the build system) and still offer backwards compatibility to earlier versions.

In this talk, we will show how we attack the Data and Infrastructure challenges for Deep Learning. Specifically, we will show how we integrated Tensorflow with the world's most scalable and human-friendly distribution of Hadoop, Hops (www.hops.io). Hops is a new European distribution of Hadoop with a distributed metadata architecture and 16X the performance of HDFS. Hops also includes a human-friendly UI, called Hopsworks, with support for the Apache Zeppelin Notebook. We will show how users can run tensorflow programs in Apache Zeppelin on huge datasets in Hadoop. Moreover, we will show how Hopsworks makes discovering and downloading huge datasets a piece of cake with peer-to-peer sharing of datasets between Hopsworks clusters. Within minutes, you can install Hopsworks, discover curated important datasets and download them to train Deep Neural networks using Tensorflow. Hops is the first Hadoop distribution to support Tensorflow.

The syslog-ng application is an enhanced logging daemon, with a focus on central log collection. It collects logs from many different sources, processes and filters them and finally it stores them or routes them for further analysis. From this session you will learn (using examples from syslog-ng) why and how to parse important information from incoming messages, and how to route logs, feeding downstream systems using arbitrary formats. We will also discuss how the client – relay – server architecture can solve scalability problems. Also, I will present some of the recently introduced “Big Data” destinations of syslog-ng, which can help to scale your infrastructure even further.</p> PUBLIC CONFIRMED Lightning Talks https:/fosdem.org/2017/schedule/event/syslog_ng_scaling/ H.2215 (Ferrer) Peter Czanik PUBLISH 5531@FOSDEM17@pentabarf.org 5531 updates_with_ostree updates_with_ostree Software updates with OSTree Why and how en en_US Embedded, mobile and automotive 2017-02-04 17:30:00 +0100 2017-02-04 18:00:00 +0100 00:30:00:00 20170204T173000 20170204T180000 00:30:00:00 Software updates with OSTree- Why and how <p>Security reasons and market demands dictate that software in a connected embedded Linux device should be updated regularly.

The bearing estimation method relies on the following principle: by considering the signal received at several points along its trajectory, the receiver implicitly creates a virtual multi-antenna array (similarly to synthetic aperture radar systems) that can be used to estimate the bearing of the radio transmitter. Virtual multi-antenna arrays have two major differences with conventional multi-antenna arrays: 1) the position and orientation of each antenna in the virtual array depends on the movement of the receiver and must be estimated; and 2) the local oscillator (LO) offset between transmitter and receiver adds a phase offset to the signal received by each “virtual” antenna, which must be estimated and compensated for. The first problem is solved by using an inertial measurement unit (IMU), which can provide the relative position and orientation of the receiver for short time periods. The second problem is solved by expanding the signal model that is used in bearing estimation algorithms (such as MUSIC) to account for LO offset. The proposed system is implemented on a USRP-N210 SDR with an external high-end IMU and tested in an anechoic chamber. The SDR implementation is a mixture of FPGA and software development, while some parts of the data are processed off-line. The results show that our method is indeed feasible, with bearing estimation errors of only a few degrees. We then present the first efforts of an implementation on a USRP-E310 SDR which has an integrated, lower-quality IMU.</p> PUBLIC CONFIRMED Software Defined Radio https:/fosdem.org/2017/schedule/event/multiantenna/ AW1.120 Francois Quitin PUBLISH 5781@FOSDEM17@pentabarf.org 5781 ruby_diy_home_monitoring_with_ruby_and_pi ruby_diy_home_monitoring_with_ruby_and_pi DIY: Home monitoring with Ruby & Pi en en_US Ruby 2017-02-04 17:45:00 +0100 2017-02-04 18:35:00 +0100 00:50:00:00 20170204T174500 20170204T183500 00:50:00:00 DIY: Home monitoring with Ruby & Pi <p>Ruby and RaspberryPi are available to us for quite sometime and this talk is meant to discuss how to use Ruby to explore things on a RaspberryPi.

Furthermore, we apply the method to describe operational conditions of a Hadoop cluster. Our experiments provide first results and allow a classification of the cluster state related to current workloads. The temporal networks show significant differences for different operation modes. In reallity we would expect mixed workloads. If such workload parameters are known, we are able to handle a-typical events accordingly - which means, we are able to create alerts based on context information, rather than only the package content. We show an end-to-end example: (1) Data collection is done via python, using the sniffer script; (2) using Apache Hive and Apache Spark we analyze the network traffic data and create the temporary network.

Developing a deeper understanding of minorities in tech. <p>Diversity User Research: Becoming a Better Listener - Gloria Dwomoh</p> <p>In order to understand the struggles and/or challenges of minorities in tech and foster a safe environment for their inclusion, we need to be better listeners. One way we are able to get access to the voice of our users is through user research. However in order to increase effective communication we need to learn the art of listening. Several of us were taught to speak, read and write, but we simply assume we know how to listen. There is a saying that less than 2% of people have had any formal education on how to listen, while that is a skill that many of us use in our daily lives. Through this talk we will understand the difference between hearing and listening; we will also explore active listening and how it can better help us in our user research.</p> <p>Women in Open Source Technologies - Kristi Progri</p> <p>The Gender Gap is one of the most talked topic since forever, and still a Gap. Where are the women in Open Source? Why is the gap so big? Women participation in open technology and culture is very important so we should all pay more attention. This talk will be focused on the large steps we can take to reduce this gap. Also we will share out experience at our hackerspace in Tirana, Albania since we have lots of women there.</p> <p>Let's face it: Gender Diversity in Tech is in a quite bad shape. The sad thing about it is that it's even more noticeable in many Open Source communities in particular. But why is gender diversity important?</p> <p>It’s not just diversity for the sake of diversity. If men and women are equally intelligent, statistically speaking, then out of the smartest ten people in the world, five should be male and five should be female. Thus, if your team is anything less than an equal balance of men and women, then your team is probably not the best it can be.</p> <p>Unfortunately, if we take a look at a random sample from GitHub active contributors from 2015, just 5.4% of GitHub users with over 10 contributions are female.</p> <p>Let's talk about the ways we can fix this and what efforts Mozilla does to improve this and how you can help Mozilla help the community, concretely with Womoz (Women at Mozilla) and the Diversity &amp; Inclusion Team at Mozilla.</p> PUBLIC CONFIRMED Mozilla https:/fosdem.org/2017/schedule/event/mozilla_diversity_user_research/ UD2.218A Kristi Progri Gloria Dwomoh PUBLISH 5903@FOSDEM17@pentabarf.org 5903 armadito_bof armadito_bof Armadito Antivirus en en_US BOFs (Track B - in H.3228) 2017-02-04 18:00:00 +0100 2017-02-04 19:00:00 +0100 01:00:00:00 20170204T180000 20170204T190000 01:00:00:00 Armadito Antivirus PUBLIC CONFIRMED BOFs (Track B - in H.3228) https:/fosdem.org/2017/schedule/event/armadito_bof/ H.3228 PUBLISH 5876@FOSDEM17@pentabarf.org 5876 upipe_meetup upipe_meetup Upipe meetup en en_US BOFs (Track A - in H.3227) 2017-02-04 18:00:00 +0100 2017-02-04 19:00:00 +0100 01:00:00:00 20170204T180000 20170204T190000 01:00:00:00 Upipe meetup <p>Upipe is primarily designed to be the core of a multimedia player, transcoder or streamer.

One of the key features of Xen is that it is OS agnostic, meaning that any OS (with proper support) can be used as a host. Xen has a long history going back to the 90s when it was designed and the early 2000s when it was released. As a consequence of this, many of the assumptions and virtualization techniques backed into it are now superseeded by new hardware features, that make virtualization more transparent from an OS point of view.</p> <p>This talk provides an overview on the different kind of guests supported by Xen and how these new hardware features are used in order to improve and evolve them. It also describes the design and implementation of a new guest type, called PVHv2, and how it can be used as a control domain (Dom0).</p> PUBLIC CONFIRMED Virtualisation and IaaS https:/fosdem.org/2017/schedule/event/iaas_towahvm/ UB2.252A (Lameere) Roger Pau Monné PUBLISH 4923@FOSDEM17@pentabarf.org 4923 ichat_gateway ichat_gateway Updating reSIProcate iChatGW for any XMPP client Getting Started with iChat Gateway en en_US Real Time Communications 2017-02-04 18:50:00 +0100 2017-02-04 19:00:00 +0100 00:10:00:00 20170204T185000 20170204T190000 00:10:00:00 Updating reSIProcate iChatGW for any XMPP client- Getting Started with iChat Gateway <p>The talk consists of an introduction to iChat gateway, tech and protocols used to build it, what new features are being build into it and why we should use ita and a working demo.
