Being a new domain, there are very few Blockchain technology resources to learn the best practices for building applications that perform well at scale. 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.
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.

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.
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.

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 & 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.
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.
Attendees should come away from this talk with everything they need to know to get starting using, developing with and contributing to openSUSE Kubic.

The RAPIDS project is the first step in giving data scientists the ability to use familiar APIs and abstractions while taking advantage of the same technology that enables dramatic increases in speed in deep learning. This session highlights the progress that has been made on RAPIDS, discusses how you can get up and running doing data science on the GPU, and provides some use cases involving graph analytics as motivation.

The technological industry claims that around 30% of their work force are women. And that percentage decreases down to 20% when focusing on the tech. teams.
If we analyze open source communities, those hardly reach 10% of the population as this is the case of the OpenStack Foundation or the Linux Kernel.
This talk will show previous analysis and data publicly available with this respect, and an analysis of the Python community [1] to compare to.
In addition to that, this talk will provide the steps done up to having the data: retrieving, curating, cleaning and visualizing the information with Python. For this process GrimoireLab, and specifically Perceval [2] was used used for retrieving information. Perceval retrieves information from the usual data sources found in the open source world. Then Ceres [3] is a small library that handle Perceval's data. These are the basics of the technical infrastructure.

Where before it was needed to launch a complete environment, copy the sources into it, invoke the build toolsto create the packages and then copy them back to the host, Docker has made all these steps much easier and straight forward, allowing for more rapid package production and automation.
This presentation will show a detailed use case for building packages for the Mageia Linux distribution with bm and mgarepo usages encapsulated in Docker containers. It should help any upstream packager adopt a similar approach to make his packaging task a breathe.

The companies that are behind these licenses argue that cloud providers aren't playing fair and these licenses are required to protect their investment. But is software freedom situation dependent? Can we make exceptions to software freedom to allow for practical commercial considerations? This is a critical debate that strikes at the very heart of what is free software, open source and software freedom. This talk will examine the rationale behind these licenses, whether they are "open source" and explore how we as a community can respond in a effective and responsible manner.

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.
In this talk, I will give a brief tour of our lab's recent explorations in this area. Then I will focus on a specific kind of neural networks, namely graph neural networks (GNN). These networks allow us to learn from the rich semantic relationships within code and, by training them on a self-supervised task, they have allowed us to find bugs in open-source projects. I will conclude with a brief discussion of the practical challenges in using machine learning on source code.

Care will be taken so the audience can easily transpose those to other python frameworks such as Django, Tryton or sqlalchemy. A short comparison of GraphQL with other familiar "RPC" technologies such as SOAP and REST will be provided, as well as a discussion of strengths, weaknesses and potential pitfalls.

The nice thing about this approach in that existing applicationsdo not require modifications.
However, an application cannot easily tell if the resolver is doing DNSSECvalidation, and the path between the application and the resolver isunprotected.
The solution to this, is for applications to do local DNSSEC validation.This can be done using the getdns library. The getdns library provides otheradvantages as well, such as a modern interface to DNS resolution, supportfor event libraries (such as libevent).
In this presentation I will describe getdns and show two examples of how itcan be used in practice.

That's because application containers today are a bit-for-bit representation of the container that the developer ran.
An insight here is that applications probably don't care about which versions of what libraries are in use: any reasonable libc, python3, ssl, etc. will do. But today, to fix a CVE in SSL, an entire container rebuild is required.
Enter AtomFS. AtomFS is an entirely userspace tool designed to allow operators to update individual libraries inside app containers. In this talk Tycho will cover how the tooling works, as well as what changes are needed to make application container builds work with AtomFS.

DESCRIPTION:Our technological society wants digital identities, but previous attempts undermine the user's right to control their personal information. With the advent of distributed ledgers, it is finally possible to have a digital identity that preserves the best aspects of our offline systems of identification, while also providing significant improvements. This talk will describe the challenges in creating a digital identity, and how the Sovrin network's deployment of Hyperledger Indy overcomes those challenges using open source technologies to implement verifiable credentials. The solution involves more than fancy code, and demonstrates the importance of considering the environment where a technology will function.

Yet, there are many grid based systems (geohash, PlusCodes, Mapcodes), and some even turn the thing into a business (Zippr, What3Words). I agree with the commonly stated motivation that Latitude and Longitude are not sufficient for identifying a place in both an unambiguous and human friendly way. A single string for this pair of numbers is a better representation, if only it can preserve all the information contained in the original latitude,longitude pair, something no existing geo-encoding system does. That's my goal.

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.
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.
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.

Reading foreign code is hard, and suggesting improvements is even harder. Yet a dramatic portion of code review time goes to figuring out the boring details: formatting, naming, microoptimizations and best practices. We believe that all of those can be automated with ML on Code, either learning from a particular project or from all the open source code in the world which is relevant. This talk will be about open source "analyzers" - ML-driven code review agents which deal with the boring but important details.

Linux is the dominant HPC operating system, and many HPC sites expand upon the operating system's capabilities with different scientific applications, libraries, and other tools.
To avoid duplication of the necessary steps to run an HPC site the OpenHPC project was created in response to these issues. OpenHPC is a collaborative, community-based effort under the auspices of the Linux Foundation to solve common tasks in HPC environments by providing documentation and building blocks that can be combined by HPC sites according to their needs.
In this talk I want to give an introduction about the OpenHPC project. Why do we need something like OpenHPC? What are the goals of OpenHPC? Who is involved in OpenHPC and how is the project organized?What is the actual result of the OpenHPC project?
It also has been some time (it was FOSDEM 2016) since OpenHPC was part of the HPC, Big Data and Data Science devroom, so that it seems a good opportunity for an OpenHPC status update and what has happened in the last three years. In addition to previous mentioned topics I would also like to give an outlook about upcoming releases and plans for the future.

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. Intended audience is technical and managerial individuals who are familiar with network visibility.

It offers extensive core functionality and provides over 200 extension modules. Therefore it can be challenging as developer to decide which of the available APIs to use for your development. This is especially true if you want to integrate your extension later into the project upstream source code repository.
This talk will start with a quick overview of the new functionality in the current major release 5.2. It will then highlight important changes in the last year for developers which are using Kamailio or developing extensions for it. Several code examples describes how to achieve a good security and performance. The talk will also provide guidelines about the development process, contributions acceptance and community interactions.

Application of virtualization call for trustworthy solutions. Complexity defeats trust.
Microkernels with virtualization extensions and user-level VMMs on top are a approach to mitigate complexity. Modern microkernels like seL4, the NOVA microhypervisor, Genode's -hw- kernel or Fiasco.OC are such promising candidates. Fortunately and unfortunately, the diversity come with fragmentation of the small microkernel community. There are several VMMs for each platform tight to a specific microkernel, rendering it unusable across various kernels.
Genode supports several kernels already, so that unification of virtualization interfaces for VMMs across kernels seem to come into reach. Does it ? The talk will cover the venture and current state of harmonization hardware-assisted virtualization interfaces to fit into the Genode OS framework.

This talk's goals is to de-mystify how it works and what it does by default on Ubuntu, and how one can further configure it to either not get in the way, or do even more cool things. We will discuss how it can be used (nss, dbus, over the network, command-line, text-configs) and how to configure it (config files, command line, resolvconf, dbus, networkd, network-manager). We will cover advanced use cases for per-interface nameservers, true split-dns configuration, and optional features such as DNSSEC MDNS Zeroconf. Last we will discuss bugs, DNS violations and diss captive portals.

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.
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 .
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. We plan to use it to automate the Student Cluster Competition Reproducibility Challenge at the Supercomputing conference.

It supports a large variety of languages and technologies via bundled plugins as well as thousands of third-party plugins.
This talk will showcase the tooling and ecosystem for plugin developers, covering the whole lifecycle of creation and maintenance.
We'll start by taking a look at the IDE features for development and testing: smart code insight, highlighting, and refactorings.
How to keep up with the latest platform releases? Plugin Verifier allows you to check for any incompatibilitieslocally as well as get reports for already published versions.
The built-in exception reporter provides the data for the Exception Analyzer, which helps collect and (auto-)triage all user-submitted runtime problems.

The Modules project, also referred as Environment Modules, provides a shell command named module that simplifies shell initialization and lets users dynamically and atomically modify their environment during the session with configuration files called modulefiles.
This talk will explain the root concept behind the module command then describe how it could be useful whether as a system administrator you have to provide access to a large software catalog or as an end-user you need to juggle with different workloads combining software elements. Current development trends to further improve the modulefile standard and the module command capabilities will then be shared with the audience.

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.
In this talk, I will describe how RustPräzi is developed, the challenges we faced while compiling the entire crates.io and the future directions. Our goal is to make RustPräzi a community effort that can help in maintaining the stability of crates.io. For example, bad releases which may negatively impact crates.io can be detected and avoided.

What happens when some points are on opposite/antipodal sides of the globe? How can one create equidistant points along a line composed of one or more line segments?
We discuss solutions to those questions highlighting some of the latest developments in Boost Geometry, the library that is currently being used to provide GIS support to MySQL. The implemented algorithms are parameterized by strategies that control the accuracy-efficiency trade-off. The proposed solutions work for 3 different coordinate systems (namely, cartesian, spherical and ellipsoidal) each of which comes with its own advantages and limitations.
We sum up by briefing the plan of future development and a short discussion.

This talk is focusedon how other FOSS projects can leverage XDP. How we believe XDPshould be seen as a software offload for the kernel network stack.
The motivation is to plant FOSS seeds for collaboration by describingthat XDP offers of facilities and capabilities. But also explain thatXDP is not the magic-bullet by framing the XDP design and what layerit operates at (e.g. no de-fragmentation) and what limits XDP imposewhen enabled (e.g. no jumbo-frames).
In the second part of this talk we will focus on AF_XDP and how it canbe leveraged by the DPDK project. AF_XDP is a new socket typeintroduced in Linux 4.18, that allow the XDP driver hook to deliverraw frames into userspace. This offers new opportunities fore.g. integrating with DPDK via a Poll Mode Driver (PMD) for AF_XDP.

Astor provides twelve extension points that form the design space of program repair.Using those extension points, program repair researchers can create new repair approaches or extend those included in the framework by choosing existing components (among 33 ones) or implementing new ones.In this talk, we will first discuss the main techniques proposed on the field of automated software repair.Then, we will discuss how to execute repair approaches included in Astor framework, how to extend them, and how to implement new repair approaches reusing components provided by Astor.

DESCRIPTION:Understanding FOSS licenses are indisputably an important part of the process for contracting for IT services ranging from software agreements, professional services to create or support software, and to cloud solutions.
It’s not uncommon to find carve outs in those agreements saying that “Some Third-Party Content may be provided to you under a separate license, such as the Apache License, Version 2.0, or other open source license.” What does that mean? Are there any surprising terms to be found in those “other open source licenses”.
This presentation will briefly review the terms of some of the less commonly discussed licenses approved by OSI as “open source.” What are some of the interesting properties of these less common licenses? And do we really want to keep agreeing to use them in our contracts?

It's just too complex for external developers." Nearly twenty years ago, that was the broadly-held opinion at MySQL AB. Now, with MariaDB, there are 174 contributors to the server alone and Monty isn't the top contributor by commits or even LoC. Clearly, some things have changed, but what are they and how much impact have they had? In this fast-paced session Zak Greant, MySQL's first community advocate, will walk through some of the critical changes over the years and share some of the best (and worst) practices.

DESCRIPTION:Most people don't realize it, but the Hurd system is actually wellestablished. About 75% of Debian official packages do build fine, ithas mainstream gcc/glibc/llvm support, go and rust ports are ongoing, it can beinstalled with the Debian installer and GuixSD and Arch ports are ongoing...
Yet not so much has been happening within the Hurd itself in the past couple of years. We have notably addeda 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 beachieved with a bit of work.
This talk will discuss some of these promising features, to give a sort of ideasroadmap for contributions. Some have implementation sketches which just need to be polished tobe more production-ready, such as httpfs, mboxfs, or writing translators inmore high-level languages than C. Other features are at early stage, such asadding sound support through rump, getting complete rid of disk drivers from thekernel by moving them to userland, or also getting valgrind support. I will alsodiscuss some promising ideas, such as using rump to get support for morefilesystems.

By moving their wings, they cause an air flow. This air flow then deforms their wings back. By simulating this complex, multi-physics phenomenon, we could design better flexible wings. However, we don’t need complex software to simulate such complex phenomena.
"Make each program do one thing well" is part of the UNIX Philosophy, but it can also apply to scientific software. We should aim to simulate multi-physics phenomena with a combination of simpler software: one "expert" for each domain (for example, flows and structures). There are so many "expert programs" in the free/open-source software community; what if we could enable them to collaborate?

DESCRIPTION:The history of programmers trying to use programming languages for data files, configuration, or UI description files, is filled with horror stories. "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: making your own languages when you need them. 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. Those parentheses may be good for something in the end...

This data is being collected, analyzed, sold and aggregated to cast profiles about us by companies across the globe.
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.
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.
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.
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.
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.
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.
But how do you transmit this complex reality to the broader audience outside our community? What data is being shared unconsciously? Who are these data collectors? What is the impact of our blocking mechanisms as users?
This is precisely the problem both Local Sheriff and Trackula tackle.
In this joint talk, we will showcase how two groups of people independently built Browser Extensions to answer these questions.

The CERN OHL is a copyleft open hardware licence which was launched in March 2011. It has undergone point releases 1.1 and 1.2 and since then, but feedback from user communities, particularly those working with microprocessor cores and FPGAs has made us reconsider some of the fundamental assumptions made when the licence was first drafted. We have shamelessly taken ideas from other licences as well as introducing some new approaches, driven by the needs of users. This session introduces our new draft of version 2.0, which aims to make v2.0 more flexible than any previous version, while increasing clarity of drafting.

TypeScript code intelligence is available across many editors and even web-based tools, all provided by the same service TypeScript ships out-of-the-box with the compiler itself. This presentation gives a tour and history of how TypeScript is able to provide the same great experience to many different clients through the tsserver and tsserver protocol, as well as how it influenced and fits into newer efforts like the Language Server Protocol. I will show how it can be used to provide code intelligence features like jump-to-definition and find-references at cross-repository scale, using some of TypeScript’s newest features like declaration maps and combining it with lesser-known interesting features of the JavaScript package management tooling.At the end of this talk, the audience will know how TypeScript tooling works under the hood and how it can be combined with other tools in the ecosystem to make developers more productive. The goal is to inspire innovation in the TypeScript tooling ecosystem by showing what is possible and how.

However, Linux is full of HW-specific code which makes validation of patches impossible for individual developers, which leads to regressions. In this talk, we will explain how we solved these issues by getting inspired by Linux's development model, and how we extend it to the development of our testsuite, CI infrastructure and bug handling.

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.
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).
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.

Such code fragments are useful for language creators as performance tests, or they could provide insights on how to improve the language. With Kotlin as the target language, we discuss how the task of detecting code anomalies for a very large codebase could be solved using well-known anomaly detection techniques. We outline and discuss approaches to obtain code vector representation and to perform anomaly detection on such vectorized data. The talk will highlight examples of such anomalies found in open source GitHub repositories.

DESCRIPTION:Software release products are compiled with optimization level –O2 and higher. 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. This feature should improve debugging of optimized code built with LLVM by recovering optimized-out function parameters.

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.

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.
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.
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?
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.
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. In this mind we developed a new OpenGL visualisation engine prototype, with a better code base and better performance than current implementation.
In this talk we will showcase both the Javascript proof-of-concept and the new Java prototype. We will present state of our reflections and the results of our benchmarks. Of course technological choices are not only (and even not primarily) a question of performance, and we will take the time to discuss the various issues and limits we met in this exercise of prospective technological exploration. we will conclude with a broader reflection on how Gephi as an open source project tries to adapt to global technological changes.
We expect this talk to be useful to Java and/or Javascript developers/engineers dealing with graphs.

Specifically, DoH could promote a collective switch from local resolvers to a few global public services, and make each application independent from the user's preferences in the operating system. 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. What would be the advantages and disadvantages of a broad adoption of DoH by Web browsers, and its likely long-term effects?

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.

Recognizing of subtrees is really a common aim in compilers implementation. But it's not an easy task.I recently found that I could easily use behavior trees to do such things. However this kind of techniques could be useful in other situation.This talk want to popularize this technique by explaining how behavior trees work in common way, how to adapt then for a bottom-up tree matching algorithm.
For instance, some HTML parser provide CSS Selector function to match one node at the time optionally related to some ancestor. Here, with this kind of matching algorithm you could match many nodes in only one pass.
I create on my github a "treematching" module that use this algorithm to provide an Embedded DSL to write patterns, match any python data structure and in some case, allow you to do tree rewriting.

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. Four of these courses ran as MOOCs (massive open online courses) on platforms such as FutureLearn and edX.

But the hardware lacked open source drivers and Linux support in general. The OpenHMD project was created to solve this issue, and as it so happen it was funded by two former Chalmers students.
The consumer VR space has now grown from a crazy inventor in a garage into a large industry. But this growth has its down sides, multiple companies have their own APIs competing. Luckily these companies have agreed to work on a single API under the Khronos umbrella.
In this talk, Jakob will cover Khronos' OpenXR standard, give an overview about the current state of open source VR and what lies ahead.

LibreOffice has had the ability to use Mozilla Themes (Personas) for some time (Tools > Options > Personalization); but it kept breaking all the time, and never had an acceptable UX. Also tons of errors/warnings, and very slow search and apply processes almost brought it to the point of being killed for good. But I couldn’t let it die, started looking into the related code and the bug reports. Now it has a better UX/UI, and got most annoying bugs/crashers fixed, and is much faster.
I will try to present a summary about the journey so far, and the plans for the future.

C/C++ is a common choice for the engine layer, while C# is a popular choice for the scripting layer - the one that gameplay is implemented with, and the one available for users to mod their games with. There's multiple engines built on C# (Unity and Monogame come to mind).
When I started implementing my own runtime-moddable game with Unity, I realized how awkward C# is for scripting, and how there just might be a better language for this. In this talk we'll look at what a game scripting language ideally needs and does, why C# is not quite the best of fits, and why Typescript is - when it targets the .NET runtime!
At the end, you'll hopefully have a better understanding of how languages fit in game development and what (great!) tooling Typescript has for introspection and compiling.

While this approach still makes sense in many contexts, it is unable to provide detailed visibility when containers or virtual systems are used. This talk describes how the advent of eBPF enables the creation of monitor rich applications that can provide both network and application monitoring information to provide detailed information for both monitoring and troubleshooting. It shows how eBPF has been used in ntopng, an opensource monitoring application, and what are the challenges and pitfalls when integrating packets with system monitoring events.

It forms a global community with projects based in Belgium, Australia, UK, France, Canada, USA, Spain and Portugal, and which is still growing.
A single global team develops an online marketplace for local food enabling independent online food stores connect farmers and food hubs with individuals. It gives them an easier and fairer way to distribute their food. This boosts short distribution circuits which positively impact local communities.
Each of the local projects offer the software as Saas to their local communities who participate on the governance of the platform taking part on the decision making.
The project is sustained by the funds contributed by all the local projects that are communalized. This makes it possible to afford the development of such ambitious project, which would be impossible by each of the local communities while still allowing new local projects to join.
This talk aims to share Open Food Network's challenges around its governance and internal organization. How it successfully manages to coordinate the efforts of people scattered throughout the world while involving local communities on its design. We also touch on the tech challenges around the tech stack and infrastructure and how we envision it in the future.

And it does not help that testing them often requires complex client or server setups.By removing IO from the equation, and instead working directly with buffers, we’ll see that testing instantly becomes easier to setup, the core implementation becomes completely deterministic, and the protocol gets more reusable.This talk draws heavily from experience implementing protocols such as HTTP or AMQP. It will show how to build protocols in such a way, using the nom parsing library, cookie-factory serialization library, and a new state machine development library. And we will see how to reuse the resulting protocols, by swapping out the underlying transport (TCP, various TLS libraries, unix sockets…) or wrapping it in a nice futures based API.

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. Virtualisation has made this all somewhat easier, but it's still fiddly and difficult to make robust. It's also slow.
The new FreeBSD network stack virtualisation lets us build on the existing jails system to build test setups, execute tests and clean up in mere seconds, without any requirement for additional hardware, or even hardware virtualisation support.

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.
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.

One of the reasons the campaign did not attract enough people was a lack of enough attractive features. The feature set was kept minimal to allow a first time right chip production.The choice of HDL is important to allow to implement more features with enough productivity and without increasing the risk of having buggy silicon. As will be presented, the venerable VHDL and Verilog RTL languages are not considered ideal for this purpose.

Threads are a natural and convenient concurrency construct which is being supplanted by less convenient abstractions because their implementation as OS kernel threads is insufficient for meeting performance demands and wasteful in computing resources. Project Loom will introduce fibers as lightweight, efficient threads managed by the Java Virtual Machine, that let developers use the same simple abstraction but with significantly better performance and lower footprint. Fibers are implemented in the JDK libraries on top of scoped, stackful delimited continuations in the JVM. This session will present the current status and challenges of the project -- both of implementation and design -- one year in.

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 & 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.
This talk will introduce openSUSE Kubic, and explains how it addresses the above, being the perfect distribution for this modern age. The session will explore in some detail how Kubic is developed in lockstep with the Tumbleweed rolling release and various upstreams including kubeadm and CRI-O. Transactional Updates, Kubic's system update stack will be demonstrated and the benefits from such an atomic update approach discussed in some detail.

Upsides like increased transparency, distributed control and the elimination of duplicative administrative work are appealing, but where are the potential downsides? We no longer live in a world where we can put off a conversation about the social impact of our work. Old industries used to call negative effects of their work "externalities" and it would sometimes take decades to discover the negative social effects and environmental destruction that had been wreaked by a new technological process.

Their logic is often hidden, while their results are manifest: the free and open source movement mostly addresses this condition. Yet moving beyond transparency, there is an urgent need for awereness and governmentality on decisions made by algorithms about the social and economical context in which we live. Community driven development may be the perfect answer to this, but faces many challenges ahead.

It is extremely flexible and powerful, but can also be rather aggravating. Most people who spend a significant amount of time working on an LLVM backend probably develop a love/hate-relationship with it.
The goal of this talk is to give a brief overview of what TableGen offers -- frontend, application-specific backends, generic table emission backend, idiosyncratic type system, and these days even limited functional-style programming -- and a brief introduction on how to use it. The focus will be mostly on the frontend -- that is, syntax and semantics of the TableGen DSL itself -- rather than on specific backends.
Along the way, I want to share some lessons learned and decisions made during a major refactoring of the TableGen frontend that I undertook in early 2018 to iron out many of TableGen's quirks and shortcomings that had accumulated over the years, as well as some glimpses of the advanced TableGen uses in the AMDGPU backend that motivated that refactoring.

However, most of them focus on monitoring overall performance metrics and error rates, giving only a general idea of the health of an infrastructure.
Unfortunately, rarely occurring issues are often hidden by general trends making it difficult to completely understand infrequent, yet sometimes catastrophic, problems.
Tracers are great at tracking down sporadic problems in production environments, but the amount of data they generate can be hard to manage in the wild.
This talk will present how the work done on LTTng over the last year, notably the introduction of a session rotation mode, makes it easier to integrate fine-grained monitoring in production environments.
The talk will also cover approaches to collecting traces on multiple hosts to troubleshoot problems occurring in distributed systems using both kernel and user-space traces.

Preserving that data is important but how does it get there in the first place? Unless it can generate its own data, the application should expect the volume to be populated prior to initialization. This may seem like a trivial problem with many simple solutions but we can build on kubernetes design principles to produce a superior solution. In this session you will discover a declarative PV population pattern, observe some concrete examples how this can be applied to different sources of data, learn about some common problems in this area and how kubernetes can help to solve them. After the session you will be ready to contribute your own populator to the kubernetes community.

In February 2010, Eben Moglen predicted the wide-scale data-mining brought about by the centralization of our network infrastructure and launched the FreedomBox project. In the eight years since, FreedomBox has become a device that can decentralize the web one box at a time. Join this session to learn about FreedomBox’s approach to decentralization and the importance of three elements of its design: hardware neutrality, software freedom, and user interface.

Most open source projects have a very diverse community infrastructure with some combination of code repositories, chat, mailing lists, wikis, forums, and more. Deciding where to focus and what to measure across these many technologies can be a challenge.
What you measure can have a huge impact on behavior within the community, and you want to make sure that you are encouraging people to contribute in sane ways by measuring the activities that matter for your project.
This presentation will cover how you decide what to measure and provide some examples.

Before the GDPR, member states had a specific national approach on how to interpret the previous Data protection directive 95/46/EC. Also, lots of actors came in the spotlight: the National Supervisory Authority, different public and private entities coming from all sectors of economy. The OSS community found itself driven in this ride and even with the best intentions nobody was able to find a complete, personalized guide to implement this new ruling that in theory is so welcomed. This talk is about pointing out how the Open source ecosystem is tangential with the GDPR data protection principles. Also, it will show how are the data protection rights and responsibilities shared between the community participants and the community's infrastructure providers.

Like the language or not, the truth is JS developers have built an incredible ecosystem with libraries and tools to do almost anything. During the talk I'll show how to bring the power of F# - the functional paradigm, static typing with type inference, pattern matching, and more modern language features - to this huge and rich JS world using Fable - F# to JS compiler. Fable doesn't add any runtime overhead and generates clean JS code in conformance with new ES6 patterns, like modules or iterables, making it compatible with modern development tools, including Github Electron or React Native to let you develop not only web, but also cross platform desktop and mobile apps. I'll demonstrate how to create different types of JS applications using F# - from React-based frontend application, through mobile app using React Native to serverless services.

The values of the group connect transparency, fairness and privacy with a culture of data portability and public contributions to the commons.
In this presentation we show how people with interest in self-hosting, system administrators from not-for-profit initiatives and members of hosting collectives are federating practices and infrastructure outside of the commercial market. Early members of the recently bootstrapped network will be present to counsel the conversation.
A data-driven approach to reactive provisioning of immutable infrastructure will be outlined and put into context with the diverse needs of associated user communities in the network. This will allow to close with an outlook about how to preconceive a federated computational commons, in which user data is not tainted by hegemonic discourses.

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.
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.

Since efficiency is a typical core requirement for embedded solutions, traditionally C/C++ have been the languages of choice for writing GStreamer applications and plugins. Unfortunately, this efficiency comes at the price of safety. Even the most skilled C/C++ developers make mistakes with memory management and the results could potentially be catastrophic. Thread safety is another aspect that is central to multimedia solutions but is extremely difficult to achieve with C/C++.
Rust language is designed to be both efficient and safe at the same time. In this talk, Zeeshan will present how GStreamer's Rust bindings not only make multimedia programming a lot safer, easier and fun but also allow developers to write even more efficient code than C/C++ in certain cases.

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 and scale; full-text search and SQL. Preferably without headaches.
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:
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.

Containers are increasingly the standard mechanism for packaging, delivering and deploying software.
They provide a simpler, more lightweight architecturally significant form of virtualisation than VMs. They are a natural candidate for running microservices. But can we do better?
If we can simplify our containers, we can shrink them further, improving:- performance- security- management
In this talk I'll be discussing:- advantages of microcontainers over containers- how to build and use microcontainers- Smith (https://github.com/oracle/smith) - a microcontainer builder from Oracle- Crashcart - (https://github.com/oracle/crashcart) a tool for debugging microcontainers (and containers)

To re-establish these connections, FH Campus Wien started the project "autonome, schienengebundene, on-Demand, open-Track Systeme" AuSoDoTS (Autonomous rail bound on-Demand Open Track systems). The project's objective is to develop a concept for how to safely operate small autonomous trains, without a fixed schedule. Trains are only approaching to stations when a passenger explicitly requests them by pressing a button at the station or using a mobile app. A short track from Liesing at the edge of Vienna to Kaltenleutgeben, a small town in Lower Austria, could be one of the first test locations.

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).
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.

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.
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.
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.
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. The tool has currently mostly been tested on the new Intel Knigh Landing architecture.

Sometimes, however, allocating a bare metal machine could be essential to withstand higher workloads or harden data security. Running a container engine (like k8s) inside of a bare metal machine avoids double resource management and achieves higher density.
In this talk we will introduce the OpenStack project called Ironic - the bare metal provisioning and life cycle service that can also act as a hypervisor for the OpenStack compute service.. We will explain system design, typical hardware management workflow, upcoming features and future challenges.

The Tor network itself is only a part of what Tor is. Tor also provides privacy at the application level through the Tor Browser. The Tor Browser was designed to provide privacy while surfing the web and defend users against both network and local forensic adversaries. The same properties can be adopted by applications and services wishing to integrate the tor network in their architecture. Furthermore, onion services provide better authentication and assurance of who you are talking to. With onion services Tor can provide bi-directional anonymity by making it possible for users to hide their locations while offering various kinds of services, such as web publishing or an instant messaging server. This talk is going to explain how it is possible to integrate tor and build onion applications.

It allows the operating system tointeract with the supervisor execution environment (SEE). The SEE alwaysruns in higher privileged mode than the supervisor OS. It can bea simple bootloader in low-end hardware platform, a hypervisor-providedvirtual machine in a high-end server, or simply machine mode software inbare metal systems. An unchecked rapid development of many RISC-V systemscould lead to incompatibilities between different systems SEE, preventingthe use of a common OS binary image.
The RISC-V ISA has defined SBI to provide a cleaner interface for thesupervisor OS which makes virtualization and bring-up of new hardwareplatforms much easier. In hypervisor extended supervisor (HS) mode, an OS orhypervisor interacts with the machine through the same SBI as an OSnormally does from supervisor mode. An HS-mode hypervisor is expected toimplement the SBI for its virtualized supervisor (VS) mode guest. Thecurrent RISC-V SBI only defines a few mandatory functions such asinter-processor interrupts (IPI) interface, reprogramming timer, serialconsole, and memory barrier instructions. Many important functionalitiessuch as CPU/system power management are not yet defined due todifficulties in accommodating modifications without breaking backwardcompatibility with the current interface.
This talk presents the ongoing work to make SBI an extensible yet robustspecification. The proposal to extend SBI is based on the foundationpolicy of RISC-V i.e. modularity and openness. It will always bebackward compatible with previous versions including the existing akalegacy version. To achieve that, the focus will be only to develop aBase SBI extension that will contain feature list, version and vendortype queries. Once that is ratified, the future extension such asCPU/system power management, vendor extensions can be developed inparallel. The use cases and calling convention of these extensions willbe discussed in details. We will also talk about a referenceimplementation i.e. OpenSBI for the SBI specification. This project willbe licensed under most permissive software license which will alloweverybody to reuse the OpenSBI code base in their favorite softwareeco-system in whatever way choose to do so. This will help in reducingSBI fragmentation in future as well.
In the spirit of the open design nature of RISC-V, the goal of thispresentation is to continue the open discussion leading to theformalizing RISC-V SBI specification simplifying both hardware andsoftware designs and doing so, contributing to further development ofthe RISC-V ecosystem.

Its simple match-action abstraction eases network management, while providing enough flexibility to define complex forwarding pipelines. OpenFlow, however, cannot express the many packets processing algorithms required for traffic measurement, network security, or congestion diagnosis because it lacks a persistent state and basic arithmetic and logic operations.
This talk presents Oko, an extension of Open vSwitch with support for BPF actions. We implemented a first userspace prototype over Open vSwitch-DPDK. Our userspace BPF VM relies on the ubpf project, extended with a rudimentary verifier and support for persistent data structures (BPF's maps).
We compare the performance of our prototype for several packet processing applications with a second setup in which applications run as secondary DPDK processes exchanging packets with Open vSwitch over a shared memory (zero-copy DPDK Ring Port setup). Our Oko setup offers a near 2x performance improvement over this alternative setup.

However, ever since row-based replication was introduced, ithas also been widely used as an integration point between a MySQLserver and other components in an IT infrastructure. It is often usedas a capture-data-changes stream, as a source of data forextract-transform-load operations or even as an event notificationtrigger (e.g., propagating transaction information to proxy layers).
Commonly deployed setups revolve around collecting/subscribing to datachanges and propagating these to downstream consumers through amessage bus, like Kafka for instance.
This session will present such use cases, highlighting the additionalmetadata added to the binary log in the latest releases, explain howto efficiently make the most out of these and how to optimize theimplementation of a change capture procedure. We will also showcasea couple of example plugins that tap into the server's binary logstream and export it even before it reaches the binary log files.

The challenge with a TV is, that it needs to be operated with a remote control. Which means, every selectable element on the screen has to be connected to a parent element (i.e. it needs to have a way to navigate to and from itself). In other words, it can be accessed just by pressing the 4 navigation keys on your remote control.
To achieve this, graphical elements on the screen are grouped into graphs, which are then connected together after the creation process.
The talk will cover:

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.
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.
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.

Of course not. You're a sensible person.
From a small footprint to a super-fast spin-up time, the reality of containers is a far cry from the reality of an OpenJDK binary execution.
So how do we bring these two disparate visions closer together?
Simple! We jlink the required JDK modules to generate a smaller footprint, then leverage alternate JVMs for performant startup!
I promise, the reality is simpler than that sentence. :)
Drop by and see what I mean.

Its generic nature allows to create new services based on an existing cryptographic and networking backend.
The presentation will start with a short overview of the RetroShare software and motivate the need for a JSON API to safely access the features offered by the core of the software.Our JSON API, to be released in December 2018, uses clever techniques to automatically generate handles from existing code based on Doxygen capabilities as well as a very compact serialization technique.We will explore the potential of the JSON API with concrete examples including the --preliminary-- web interface and Android RetroShare clients.Finally, a call to developers will be made, based on generic examples, while proposing multiple ideas of distributed services to be developed on top of it.

As this renders the software no-longer free and open source, GNU/Linux distributions such as Debian and Fedora are unable to ship Redis Labs' versions of the affected modules to their users.
This talk from a long-time (2009) Redis user & developer will outline the history, background & response to this flavour of license, as well explain how this it at odds with communities in which they participate in and are ultimately are a short-sighted & retrograde step for the companies and individuals that are advocating for them.
Furthermore, this talk will ask some thought-provoking questions about how the the conversation around "sustainability" in open source is being co-opted by foregrounding of financial elements to the detriment of the principles & people that have so clearly and demonstratively served us so well in the past four decades.

Applications have to be ported manually to non-standard OSes before gaining from impressive benefits, like superb performance, great isolation, and a small trusted compute base. Unikernels can be instantiated in tens of milliseconds or less. They are tiny with low memory footprints of a few MBs or even KBs. They can achieve high network throughput of 10-40 Gb/s with a single CPU core and they enable running thousands of concurrent instances.
We are going to present the Xen Project/Linux Foundation's open source Unikraft project. Its high level goal is to provide an automated tool to build unikernels without requiring the time-consuming, expert work as today. In addition, Unikraft targets support for multiple "platforms": Xen, KVM, containers and bare-metal.

Often a team's engineering efforts are spent on the backend, while the cli doesn't receive the same level of attention. This can result in hard-to-test tools, and dumping maintenance of them to whoever most recently joined the team.

It is rewarding to see the project grow and people contribute, but it can become frustrating and burdensome when your side-project comes to dominate your free time. If you're fortunate, you might be employed to work full-time on your open source project or even start a company around the project; then what? What is your new relationship "with the community?" How do you balance the motivations of various contributors, yourself included, within the project?
In this talk we'll look at the history of the Jenkins project, from its origins as a side-project at Sun Microsystems to the growth of the project and on to the relationship with CloudBees, Inc. We'll look at what has and, perhaps more importantly, what hasn't worked well as CloudBees has grown in tandem with the Jenkins project. We will examine the evolving cultural dynamics of the project and the challenges of wearing two hats: corporate and open source.

Technically it may be classified as syntactically scoped, statically typed, call by value, functional programming language. In practise Never offers basic data types, assignment, control flow, exceptions, arrays, first order functions and some mathematical functions to make it useful to calculate expressions. The language itself is an example how minimalistic language can be created as a hobby project in several months and used to solve interesting problems.
The presentation outlines Never language features and presents its capabilities by demonstrating simple neural network supervised learning algorithm. During the talk audience will learn why the language was created, which solutions are used under the hood and about its possible future extensions.

There are increasingly more ways to run server-side software, with many more independent services and more points of failures, the list goes on! On the plus side, there’s a lot of great tools and patterns being developed to try and make things simple to assess and understand. This talk covers how metrics and monitoring can be leveraged in a variety of different ways, auto-discovering applications and their usage of databases, caches, load balancers, etc, setting up and tearing down dashboards and monitoring automatically for services and instances, and more.
We’ll also talk about how you can accomplish all this with a global view of your systems using both Prometheus and Graphite with M3, our open source metrics platform. We’ll take a deep dive look at how we use M3DB, distributed aggregation with the M3 aggregator and the M3 Kubernetes operator to horizontally scale a metrics platform in a way that doesn’t cost outrageous amounts to run with a system that’s still sane to operate with petabytes of metrics data.

The EBU and NAB co-funded a project to create a demonstrator for a radio device able to be entirely controlled by voice. This demonstrates the concept of the 'Single Voice Service List', and uses openly-standardized metadata from the broadcaster (using RadioDNS lookup, ETSI 103 270, and the Service and Programme Information data, ETSI TS 102 818) to automatically select between DAB+/IP/FM. The project was implemented by hacking the underlying Alexa Voice Service SDK.

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.
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.
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.
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.

This protocol introduces periodicity to cryptocurrency payments through an ongoing relationship between the merchant and the customer without unintentionally disclosing personally identifiable information. We are creating this protocol to allow us to offer a truely end-to-end private subscription data storage solution built with Tahoe-LAFS. By sharing it, we hope that other subscription services will implement our protocol and further the adoption of cryptocurrency payments in real world retail use cases.
Although this protocol is currently a work in progress, we have already specified some design decisions. For periodicity, we are avoiding a payment pre-authorization design to keep the user in control of their keys. And for privacy we are utilizing Zcash shielded transactions and the coming improvements in the Sapling release.This protocol is being created by the Least Authority team with support from the Zcash team.

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.
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.
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.
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.

The reason is that developing aspecializer for a new language remains still a from-scratch endeavor, and it'shard.
It is the lack of general-purpose flexible program specialization tools thatoften leads projects to creating custom just-in-time compilers for theirspecific use cases. These compilers, even if based on mature compilerinfrastructures such as LLVM's, immediately become way harder to develop andmaintain than simple interpreters they make obsolete. In many cases, however,program specialization could bring the proverbial 80% of the benefits for afraction of the cost, while maintaining simplicity and testability of theoriginal design.
It is our belief that developing a specializer for a new language should be aseasy as adding some supporting syntactic and semantic definitions to alanguage front-end and reusing an existing specializer in the middle end.
Such a language-independent specializer preferably has to:
We will present the design and the prototype implementation of amulti-stage offline specializer generator that ticks most of these boxes. Thegenerator is based on LLVM and runs in compile time along with the compilationof a source program. It is controlled by intrinsics and function and parameterattributes in LLVM IR. Being developed in the middle-end of the LLVMoptimizer, the specializer generator can be used with any language front-end.We will talk about some elements of its design, its limitations, and ways toimprove.

Still today many critical issues remain in protocol implementations, as their root causes have not been addressed. 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.
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.

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.
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.
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.
The code is licensed under the GPLv3 license and is available at the https://gitlab.com/equinox-sdr repository.

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.
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.

Because of its flexibility, performance and ease of use, Netmap is an attractive solution to implement high-speed portable Virtual Network Functions. This talk shows how to write packet processing applications using the Netmap API, and run them inside QEMU VMs, over passed-through Netmap interfaces. With Netmap, applications running in two VMs or containers can exchange up to 20-30 Mpps (per-core) at minimum packet size.

For all the internal mapping we use OpenStreetMap — and we are naturally interested in it having zero road errors. One way to ensure that is to validate it against tens of thousands GPS traces we get every day. In this talk we'll look at the relation of traces and map data in OSM, find a few ways to improve OSM using these traces, and see the validation system we made.

This has been achieved by intensive profiling of multiple use cases and refactorings derived from the analysis.
This talk will take a look behind the scenes and shows how profiling tools can help to understand performance bottlenecks in Eclipse based products and Java applications in general. Attendees will learn about the YourKit Java Profiler tool, which while being a commercial product can be used for free on Open Source development. I will discuss some former hot spots identified in the Eclipse platform with analysis screenshots and how they got resolved.

In particular, within the realm of IoT, some messaging paradigms are used which from a security perspective offer little to no value.Closed systems arise, yet the future data value remains unclear. Additional project and integrations costs are a direct result of delays in connections.Data quality, data transparency, and data sovereignty of users, companies, and organizations suffer as a result of this.
SOLUTIONWhat is Neuropil? We all have it in us: The fibrous network of tissue which forms the gray matter in our brain. Neuropil facilitates the networking between individual cells. It is in this manner thatthe Neuropil layer, an open source solution, assures the stable communication between machines and applications. What makes it so unique is that the secure exchange of data between the IoT devices and applications is dynamic, decentralized, and fully automated.
The Neuropil® layer, therefore, ensures data quality, data transparency, and data sovereignty all the while reducing IT costs, maximizing availability, and increasing reliability.A secure IoT is a crucial prerequisite for secure collaboration and competitive businesses.
The Neuropil® layer provides:- Automatic discovery of data channels across enterprises- Attribute based access control to authorize data exchange- Asymmetric end-to-end encryption between the participating systems- Protection of IoT devices regarding excessive payloads- High scalability without central infrastructure- Centralized governance, but decentralized messaging

In this talk we explore the underlying technologies on which these layers are built using approachable examples and demonstrations. Attendees can expect to gain an understanding of these implementations and the principles behind encryption, identity, and trust in Kubernetes.
We've got rid of GOTO and the spaghetti code it leads to in 1970's. However, we are encoutering very much the same problems when writing concurrent code even now, 50 years later. Programmers are still stuck deep in the callback hell or state machine hell. Concurrent code still looks like spaghetti. And while Go language provided a tool to write unspaghettified concurrent code to the masses, by no way are all the pieces of the puzzle in place.
This talk focuses on what's missing. It explains where the current mainstream paradigms break the vital principles of encapsulation, separation of concerns and correspondence between layout of the code and the execution flow.
It introduces a bunch of current approaches covered by the umbrella term of "structured concurrency" that attempt to solve these problems.
The talk may be interesting to anyone who has to deal with concurrency, irrespective of the language they are using.

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.
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.

A closely related issue is the overhead of handing hardware interrupts in user space device drivers. This talk discusses some specific hardware/software co-design ideas to improve the performance of microkernel multiserver operating systems.

In 2015, in a belief that FLOSS makes more economic and social sense, several of us, with a range of skillsets, worked to see where the boundaries are. Is it possible to scale beyond freelancing or contracting? Can you be a small, local, multifacted business and be paid to release code? What are the painful lessons...? And what really is a consortium anyway?
Based on learning from the Northern Ireland based Avata Industries members, this talk covers the reusable outcomes of building a small business consortium - one that is focused on using and creating open technology. In particular, it will focus on sustainability, building relationships, presenting an engaging free software business case, and the feasibility study commissioned to examine these.

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 tointerpretation 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.
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.
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.
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.

DESCRIPTION:Consider a Java application in a private banking system. A new networkadministrator is hired, and while going around, he notices that the app ismaking network calls to an unknown external endpoint. After someinvestigation, it’s found that this app has been sending for yearsconfidential data to a competitor (or a state, or hackers, whatever). Thisis awkward. Especially since it could have been avoided.
Code reviews are good to improve the hardening of an application, but whatif the malicious code was planted purposely? Some code buried in a commitcould extract code from binary content, compile it on the fly, and thenexecute the code in the same JVM run… By default, the JVM is not secured!Securing the JVM for a non-trivial application is complex andtime-consuming but the risks of not securing it could be disastrous. Inthis talk, I’ll show some of the things you could do in an unsecured JVM.I’ll also explain the basics of securing it, and finally demo a workingprocess on how to do it.

Graphs become more valuable if data from multiple sources is ingested, but in general not all users will be authorized to access all data in the graph, given privacy laws on personal data and corporate policies. Since it is not practical to maintain separate copies of large graphs for the different authorization groups, a technical solution for access control is required. This presentation deals with this issue and discusses techniques to provide access to graph data under heterogeneous confidentiality regimes. In particular, an add-on TinkerPop API is presented that provides an abstration to the required filtering and supports the auditing of gremlin queries for validity.

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. The open gateway framework is node.js based and targets at decentralized ‘Internet of Things’ with privacy and security in mind. This talk is supported by a demo.

DESCRIPTION:How can we be sure of the continuous configuration management proper operation? How to expose factual topic-related reports to dev, sec, managers, customers...?
We believe that, in order to deliver the full business and collaboration value of continuous configuration management, the solution needs to go further than simply applying policies - it must ensure configuration reliability; prove historized application and status; share it to other teams; notify of any drift with a relevant context.
This talk will present why and how we should be concerned about transmitting factual measures on infrastructure management to all parties involved. We will also guide you through the journey to include a full-fledged reporting feature in a configuration management solution.

Traditionally, tools like CloudFormation, ARM templates and Terraform employ text-based templates, which tend to be verbose and hard to create and reuse.
What if instead of configuration files you could just use Typescript? Meet Pulumi—an open-source library which brings types, components, conditionals, and much more to your cloud infrastructure definition.

There are the often talked about challenges, like making sure you use battle tested encryption primitives and use them correctly, and striking the balance between security and usability. 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.
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.By the end of this talk, attendees will be made familiar with some of the unique challenges that come with building end-to-end encrypted applications and some alternatives for solving them.

This is the aim of VBoard, a 100% open source web application that allows building visualizations and dashboards in 3D and VR using A-Frame as its core render library. The data is retrieved in real time using a ElasticSearch, and VBoard saves its objects (visualizations, dashboards) in it.
In this talk I will show the functionality of VBoard, starting with a general overview, its installation steps and a simple step by step user guide. All of this in order to build a 3D and VR dashboard from scratch. To finish, I will show examples of what kind of visualization/dashboard you can build with VBoard using data retrieved with GrimoreLab related to open source projects (e.g., commits, usernames, repositories, etc.).

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. We'll look at the architecture of Numba and explore how we can extend it to ensure our code can be accelerated without having to trade in expressiveness.

It was from the maintainer of something called SReview (https://github.com/yoe/sreview), which happens to be the software FOSDEM uses to capture, post-process and publish the videos of all the talks at the conference.
Over the past 10 months we redesigned the SReview interface in a user-centred, collaborative, iterative and open way. This talk explains how we went about it. Using a model of the "ideal" design process as a reference, we'll show where we deviated from it and why. The moral of the story? There is no best way of doing design. The best way of doing design is the way that suits your project.

This either causes several almost identical images being provided or only very few boards being supported. The talk will present a single image designed to boot various ARM64 based SBCs, including boards from different SoC vendors, like Allwinner and Rockchip. It uses the different start sector used by the SoC families, with some tweaks to allow coexistence between the different firmware components, plus some runtime detection of the SoC and DRAM chips used.This can be used for instance by distributions to provide generic distribution installer images.

It is a protocol designed to allow for packet retransmissions between broadcast equipment, something which in the past had been vendor specific. Unusually for professional standards, it has a public specification and thus has already been implemented in a number of open source projects. This talk will took about the good parts and the bad parts as well as comparing it with traditional transport protocols such as TCP.

They reach a certain point and start failing, often very suddenly and surprisingly.
This talk is about some of the most common scaling "discontinuities" in PostgreSQL, and how to plan for them and mitigate them. Why is SERIAL a bad primary key on high-insert-rate tables? What happens when autovacuum can't keep up? How do you know you don't have enough memory for your queries? What happens when a query that worked just fine before suddenly has a horrible plan?
Drawn from real-life examples, we'll go over these and show how to fix them… and avoid them in the first place.

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.
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.
Finally, the talk will dive into the great ONOS open-source community, its strengths and how to become part of it.

In this talk, I will:
(1) give a general overview of the CSA, how it works and its limitations;
(2) show how we extended the existing heuristics to remove spurious bug reports: path constraints produced by CSA are encoded as SMT problems, SMT solvers precisely check them for satisfiability, and bug reports (whose associated path constraints are unsatisfiable) are removed;
(3) show the evaluation of our refutation algorithm when analyzing twelve widely used open-source projects;
(4) show how to set up an automated testing environment using scripts provided by the CSA infrastructure. As an example, I will show how to set up the twelve projects used to evaluate our refutation algorithm: https://github.com/mikhailramalho/analyzer-projects.
The target audience of this talk is anyone interested in learning more about the clang static analyzer and in analyzing their C/C++/ObjectiveC projects.

DESCRIPTION:RISC-V is an increasingly popular architecture for embedded systems. For such systems, compiled code density is a critical factor, particularly for deeply embedded and low power systems, where memory may be veryconstrained. 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.
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.
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.

Over the years the community has created numerous cool cases, add-on boards and peripherals for optimized gaming.
In this presentation you will learn how to use cutting edge free and open source technologies such as KiCAD and OpenSCAD to create a gamepad as a Raspberry Pi HAT (Hardware Attached on Top) with device-tree fragment for mapping the keys saved in an EEPROM connected via I2C. Exact steps for setting it up and playing retro games in emulators on RetroPie and Raspbian will be provided. Furthermore we will discuss the benefits of the open source hardware and the certification program of Open Source Hardware Association (OSHWA).
The presentation is appropriate for anyone interested in low-cost retrogaming and modern free and open source software technologies. No previous experience or hardware knowledge is required. Apart from retrogaming enthusiasts, the talk is appropriate for wide range of developers, makers, and students. Hopefully, the presentation will encourage the attendees to grab the soldering iron and start prototyping retrogaming compatible hardware for fun and profit.

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.
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.
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.
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.
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.

That's right, by default all Kubernetes secrets are base64 encoded and stored as plaintext in etcd. Anyone with access to the etcd cluster has access to all your Kubernetes secrets.
Thankfully there are better ways. This lecture provides an overview of different techniques for more securely managing secrets in Kubernetes including secrets encryption, KMS plugins, and tools like HashiCorp Vault.

As many other Apache projects, Beam first used Java as its API language. Unsatisfied with the status quo, Beam developers launched the portability project to enable other languages to run with Beam. Currently, Beam has a Java, Python, and a Go API.
Ultimately, these languages won't just coexist in Apache Beam, but they will complement each other in cross-language data processing jobs.
In this talk we will learn how it is possible to support multiple languages and why it might be a good idea to combine these languages in data processing jobs.

As the technical details greatly varies across platforms, a project called Waffle was introduced in 2012.
Today Waffle is a core library, used heavily for testing GL drivers with piglit.Additionally, the library provides a simple API which allows easy integration and use of GL application across both X11 and Wayland.
For newcomers, a quick outline of the project and its usecase will be provided. Then we'll walk through the project evolution - from platforms supported, feature set and developer base.The main part of the talk will focus on the work done to improve the quality of the project. The CI that was recently deployed will be presented, static analysis tools and code coverage.
Finally, we'll talk about the outstanding "issues" of the projects - from missing features, additional testing, tooling required and everything else that is preventing people from using the project.

It was originally developed in C due to its low footprint and high performance. Recently Python language bindings were added, so you can collect, process, and store log messages using embedded Python code.
Learn how to customize your log processing infrastructure in Python using syslog-ng, integrate your logs to local and cloud services, and the implementation details and benefits of such solutions.

But is it worth making open source hardware using expensive proprietary software? Of course not!
In this presentation Leon Anavi will share his experience in developing IoT by designing printed circuit boards (PCB) with the free and open source EDA tool KiCAD, the open source hardware certification program of OSHWA, crowdfunding opportunities for low volume manufacturing and open source success stories for building a community. Practical examples based on the certified open source hardware development boards ANAVI Light Controller and ANAVI Thermometer will be provided. The talk also contains information about open source hardware licenses, KiCAD getting started guidelines, tips and tricks for avoiding common mistakes.
Always take with a pinch of salt anything that a software engineer like Leon says about hardware and in the same time have in mind that if he can do it, anyone can! Hopefully the talk will encourage more people to use KiCAD, join the open source hardware movement and certify their open source devices at OSHWA.

Sometimes governance "just happens" but more often than not, projects end up with some things that work and some that don't. Transparency, clear expectations and compassion go a long way towards helping you find people who support your vision but can still bring new ideas to the table when it comes time to talk implementation. Your project's governance should reflect your values and empower individuals to succeed within its structure.
Maintaining and scaling your project is easier when you've laid a good foundation. The community is mature enough that we can learn from what's already been done and set up new projects for success. This talk will cover some of the big red flags you'll want to avoid as well as some of the structural details that will help avoid issues later on.

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.
The GraphBLAS initiative is an effort to design a set of standard building blocks that allow users to formulate graph computations in the language of linear algebra, using operations on sparse adjacency matrices defined on custom semirings. Since its inception, GraphBLAS has been implemented for multiple languages (e.g. C, C++, and Java).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.
Graph analysis has a significant overlap with network science, 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 (monoplex) 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 (multiplex) and emerge by different types of interactions. To illustrate such analyses, we calculated multiplex clustering metrics on the Paradise papers data set 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 in days. Hence, we adapted techniques from GraphBLAS to optimize the computations to finish in a few minutes.
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 speedup the calculation of multiplex graph metrics. We present the lessons learnt while experimenting with sparse matrix libraries inC,Java, andJulia. Our graph analyzer framework is available as open-source.

Typically a user/orchestrator must somehow provision vSwitch cores on-the-fly or even over-provision these cores up-front, in order to ensure the vSwitch can handle the traffic going to and from these workloads at any given time.This talk introduces an approach/approaches to vSwitching that distributes the vSwitching work alongside worker cores, and as a result automatically scales with the amount of work being done on the platform. The approach is likely to be superior to existing approaches in terms of compute cost.

However, these mechanisms are not sufficient for the security demand because Kubelet and CRI/OCI runtimes require the root privileges on the hosts, and these components are seriously bug-prone. The dependency on the root privileges has been also problematic for promoting Kubernetes to the HPC world, where users are often disallowed to install software as the root.
In this talk, Akihiro and Giuseppe will show the community’s ongoing work for making Kubernetes deployable and runnable as a non-root user, by using User Namespaces. The main topics of discussion will be UID/GID mapping, unprivileged Copy-on-Write filesystems, Usermode networking (Slirp), and Cgroups.

While Rust has support for many of the OOP concepts in one way or another, there is no easy way for implementing subclassing or inheritance.
The topic of this talk will be how to implement subclassing and inheritance in safe Rust, based on the GObject C library. The GObject library is providing Java/ObjectiveC-style OOP features to C. It is used by the GTK+ UI toolkit, the GStreamer multimedia framework and various GNOME libraries.
Apart from reasons why you would want to do this in Rust, this talk will cover the new implementation for subclassing that was recently integrated into the existing GLib/GObject, GTK+ and GStreamer bindings. These bindings allowed usage of existing GObject types before, but didn't provide any features to create new GObject types. In addition to usage of the subclassing implementation, a couple of details about the implementation will also be explained.
Last but not least, an outlook in the future will be given for how one can take this even one step further with procedural macros to allow writing code that looks very close to Java or C#.
This talk will not only be interesting for those who want to make use of GTK+ or GStreamer and extend those libraries, but will also cover various aspects about safely interfacing with C libraries from Rust and all kinds of type tricks to teach the Rust type-system about subclassing and making use of the type-system for enforcing various invariants at compile-time.

Instead of resorting to a full GPU reset mechanism from the get go when things go wrong there are less aggressive options that could help us achieve a faster and smoother recovery from a hung GPU. This talk will go over one such mechanism that includes a low latency engine based reset approach through the use of a GPU watchdog timeout. The talk will end by discussing a specific use case under Chrome OS that shows how all the pieces fit together (including how media drivers can make use of this mechanism from user space) and also how a compositor could take advantage of this approach and improve the user experience.

At its opening in 1956, the 25m dish was the largest fully steerable radio telescope in the world. These days it is run by a group of volunteers, who have restored and rejuvenated the instrument. It is used for radio astronomy and amateur radio, but also for outreach and art projects, to name a few of our activities.
We perform observations of pulsars, the hydrogen line of our own Milky Way and other galaxies, have a SETI project, and have recently participated in our first VLBI observation. We are increasingly using Software Defined Radio and in particular GNU Radio to perform our measurements. This allows for rapid development of new signal processing chains, and a lot of flexibility in how we process the incoming data.
In this presentation I will present some of the signal processing that is useful for radio astronomy, the flowcharts we have developed, and the astronomical results that we obtain with them.

If a board has a way via which the user can plug in another hardware component, unless we are talking about universal buses like USB or SDIO, the device tree has to be updated to corresponding to the change.
There are several ways how this issue can be solved. One may, for example, have a different device tree for each configuration, or one can use device tree overlays.
But what if you have a device which can, via one bus, connect several devices, and these may or may not be of the same kind? The number of different device trees would grow rapidly, and one could not use the same device tree overlay when the same device is connected more than one time without editing the overlay.
Fortunately U-Boot can fixup the loaded device tree before booting.
In this talk we shall describe how we used this fixup feature (hopefully in an elegant and upstreamable way) to solve this issue on Turris MOX, a modular SOHO router.

In order to achieve a solid design, it’s important to understand how the schema is then going to be used as well as the trade-offs it involves.
As Fred Brooks said: “Show me your flowcharts and conceal your tables, and I shall continue to be mystified. Show me your tables, and I won’t usually need your flowcharts; they’ll be obvious.”
In this talk we're going to see practical normalisation examples and their benefits, and also review some anti-patterns and their typical PostgreSQL solutions, including Denormalization techniques thanks to advanced Data Types.

The Prometheus Monitoring system has been thriving for several years. Along with its powerful data model, operational simplicity and reliability have been a key factor in its success. However, some questions were still largely unaddressed. How can we store historical data at the order of petabytes in a reliable and cost-efficient way? Can we do so without sacrificing responsive query times? And what about a global view of all our metrics and transparent handling of HA setups?
Thanos is an open source project that takes Prometheus' strong foundations and extends it into a clustered, yet coordination free, globally scalable metric system.
In just 20 minutes, this talk will walk you through the real, actionable steps of seamlessly transforming your Prometheus setup into a robust, global and durable monitoring system using Thanos.

To make this decision optimizer can examine the actual table data, but with multi giga- and terabyte tables, the only practical solution is to use various data statistics that was collected in advance. The better the statistics is and the more precisely it describes the actual data, the faster the plan will be, because optimizer image of the reality will be closer to the actual reality.
In this talk you'll learn what data statistics MariaDB and MySQL can collect, what statements do that, how to tell the optimizer to use it (it won't necessarily do it automatically!) and how it can make your queries many times faster.
And, of course, when not to use indexes, when up-to-date statistics is enough.

In such complex and challenging projects, automation is a key point to reduce the workload of low added-value tasks as monotonous refactoring or redundant paradigm translation.
To do so with our clients, struggled with deeply in-debt code bases, we built an in-house toolkit to support the developers in modernisation projects from detection to transformation. We created a language-agnostic model to represent code and several engines based on it: code smells and custom pattern detection, quality metrics, automatic refactoring, code generation… With this talk I would like to share what are the steps to build a toolkit to automate code’s transformation and share a few practical use cases.

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.

Built in Python, Strawberry Fields is a full-stack library for design, simulation, optimization, and quantum machine learning of photonic quantum circuits. The platform consists of three main components: (i) an API for quantum programming based on an easy-to-use language named Blackbird; (ii) a suite of three virtual quantum computer backends, built in NumPy and Tensorflow, each targeting specialized uses; and (iii) an engine which can compile Blackbird programs on various backends, including the three built-in simulators, and – in the near future – photonic quantum information processors. 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.

Private-by-design collaboration DESCRIPTION:It is often difficult to untangle technical choices made when designing systems from the values and implicit assumptions of its those systems' designers.
For many developers of open-source software, radical openness and permissionless participation have become the de facto methodology to follow when designing collaboration systems. This ideology has driven the creation of a wealth of information systems and collaboratively curated data sets which could not have been created in a top-down fashion. Consequently, different values, and thus different architectures have remained largely unexplored.
This lecture will present CryptPad, a web-based suite of collaborative tools which employs client-side encryption to restrict access to those who possess the cryptographic keys which are unique to each document. I will include an overview of the underlying architecture, and provide insight into its design process and the values that it encodes.

That's probably the part of Nextcloud most people are already familiar with. But Nextcloud takes huge efforts to go beyond handling your data and provides strong collaboration and communication tools. In 2019 most people not only want to store their data, they are looking for a integrated platform which allows them to do actual work with their data. In this context collaborative editing but also video, audio and text chat, integration with your contacts and calendars and many more play an important role. If you want to do this without losing the connection to your friends, family and co-workers strong federation capabilities are needed. Federation is at the heart of Nextcloud and was completely re-written last year based on the vendor neutral Open Cloud Mesh (OCM) specification.
Additionally to the OCM implementation which allows you to share data across Nextcloud instances, we are excited to announce that with Nextcloud 15 we joined the Fediverse with our own ActivityPub implementation. This turns every Nextcloud user into a participant of the free, open and federated social network and allow them to communicate with people on Mastodon, Friendica, Pleroma and many more. Join the talk and learn what you can do with Nextcloud and how to join the cloud federation.

Machine Translation systems often need to handle a large volume of concurrent translation requests from multiple sources across multiple languages in near real time.
Many Machine Translation preprocessing tasks like Text Normalization, Language Detection, Sentence Segmentation etc. can be performed at scale in a real time streaming pipeline utilizing Apache Flink.
We will be looking at a few such streaming pipelines leveraging different NLP components and Flink’s dynamic processing capabilities for real time training and inference.We'll demonstrate and examine the end-to-end throughput and latency of a pipeline that detects language and translates news articles shared via twitter in real-time. Developers will come away with a better understanding of how Neural Machine Translation works, how to build pipelines for machine translation preprocessing tasks and Neural Machine Translation models.

However, it turned out that parsing and centralizing these records is not as easy as you would hope. Elastic's new Auditbeat fixes this by keeping the original configuration, but ships them to a centralized location where you can easily visualize all events. You can also use Auditbeat to detect changes to critical files, like binaries and configuration files, and identify potential security policy violations. This talk shows you what can you do to discover changes, events, and potential security breaches as soon as possible on interactive dashboards. Additionally, we are combining Auditd events with logs, which are security relevant.

Less attention is paid to make the jobs of system administrators easier by providing stable configuration interfaces. These interfaces consist of configuration file formats and various utilities that often change with new major OS releases.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. We will show how to use Linux System Roles with Ansible to configure your Fedora, RHEL or CentOS systems and discuss the challenges that one may encounter when designing such a system or Ansible roles in general.

The bug, which affected the popular OpenSSL cryptographic software library, notably compromised the confidentiality of 4.5 million US patient records and cost the industry an estimated $500M.
It was soon revealed that the root-cause of the issue was that OpenSSL was precariously understaffed. Open source sustainability became a major theme overnight. Stories of maintainer burn-out made the headlines. And tentative solutions started to emerge, most of them donation-based.
In this talk we'll explore a number of existing strategies to fund open source and make it more sustainable, from patronage to dedicated ad networks. And we'll defend the idea that the best path to open source sustainability is to help companies understand the tangible business value they can get from contributing to open source.

We use it to compute the Quality Of Service (QoS) of our IT infrastructure and customers (14k servers and 5M websites in the WebHosting department).
To be able to do this we use some open source technologies :- TimeSeries databases and Pandas / Numpy for the QoS computing,- Neo4j to store the graph of our dependencies (a customer depends on several servers and some services, like databases, themselves depends on servers. If a server fails, several customers QOS are impacted),- Kafka consumer to update in real time the graph in Neo4j,- Apache Airflow to schedule the jobs used to compute the QOS of the whole infrastructure (the graph in Neo4j contains ~10M nodes).
The goal of this conference is to show you how do we assemble these technologies to construct DepC in OVH.

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. In Toro, the kernel and the microservice are compiled together and the result is a single image that can be used to launch a Virtual Machine (VM) on different hypervisors like Xen, KVM or HyperV.

Many have recognized the advantages of containerization and container platforms for traditional web server and database apps. With the expansion of IoT as well as Telco and service providers’ workloads into containers, there is an increased focus on NFV, and other non-traditional networking intensive applications. These applications require layer two and three access to high performance data planes from within containers and Kubernetes pods. In this session, we will dive into the particular requirements for layer2 and layer3 containerized applications. We will also discuss and compare some solutions such as Network Service Mesh (NSM) and Multus and how they are used for the connection and orchestration of NFV containerized workloads.

Code smells capture such poor code quality practices. Traditionally, the software engineering community identifies code smells in deterministic ways by using metrics and pre-defined rules/heuristics. Creating a deterministic tool for a specific language is an expensive and arduous task since it requires source code analysis starting from parsing, symbol resolution, intermediate model preparation, and applying rules/heuristics/metrics on the model. It would be great if we can leverage the tools available for one programming language and cross-apply them on another language.

This optimization path is available both for native methodsimplemented as callouts to C code and for methods that are defined inJava. In both cases the method needs to be flagged as a HotspotIntrinsicand provided with a JITted code implementation. The intrinsicimplementation defines the hand-crafted definition of as a high-levelintermediate representation (IR) graph for the C2 JIT. This means it canbe inlined into the IR graph for caller methods, providing even greateropportunities for optimization.
This talk will demonstrate how to implement an intrinsic by walkingthrough a specific real-life example that is currently under review as aJEP candidate. It will start by motivating the need for the intrinsicand defining the candidate as a Java method which relies on anunderlying native implementation. It will then show how the candidatecan be replaced with an intrinsic implementation, working through thechanges required in the VM, the JIT compiler front and back end and,ultimately, the assemblers for x86 and AArch64.

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.
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.
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.
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.

These may be based on foundation toolkits such DPDK, eBPF/XDP, Snabb and so on, and may implement a diverse range of network functions, applied in many combinations and on different compute platforms and devices.
The need for a consistent and repeatable, use-case driven performance validation and benchmarking approach has never been greater. Enabling both the development community and the end-user to understand, measure and verify expected performance.
Achieving great performance with Network Software, should not be accidental, it should be data-driven!
This talk explains how the FD.io CSIT project aims to meet this need by developing and providing Continuous Performance Lab platform for benchmarking, validation, performance trending and regression detection. Founded on multi-vendor collaboration, CSIT leverages deep multi-platform understanding and telemetry tools to analyze and correlate benchmarking results leading to consistent, repeatable and reliable performance validation the FD.io user base can rely on.

With the expansion of containerized application technologies, heavier, longer-living applications are looking to leverage Kubernetes. These applications may keep a complex state that is hard to relocate and may have strong hardware requirement. Thus, stopping and rescheduling them is more expensive and disruptive to the application. For such applications, an administrator would like to modify the configuration of the cluster nodes on-the-fly. In particular, this is important for network-related changes, such as setting SR-IOV cards or defining bonds. In this talk you will learn about kubernetes-nmstate. A tool that allows Kubernetes administrators to dynamically configure networking on cluster nodes.
Attendees will learn how to configure node network from the Kubernetes API

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.
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.

Today this is a popular feature, and we only do a good job of rendering this shape type when the file has a fallback rendering included. LibreOffice 6.3 will contain a long series of small, incremental improvements in this area, resulting in a large step forward when it comes to laying out SmartArt document models. This will be a major improvement for documents which don't have a pre-rendered layout included. The result affects both desktop LibreOffice and the Online. Come and see how this work is implemented, where are the still rough edges and how you can help.

Recently released Version 3.0 of this open source software incorporates a number of significant enhancements that span from the core of the software itself to the enabling ecosystem that surrounds it. 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.

Do you struggle with communication and project quality? Are you missing opportunities to make a bigger impact because of ineffective communication? Are you unsure why there is turnover among your most effective contributors? Do you see the benefits that collaboration brings to other projects, but are unsure how it could apply to you & your project team?
This session will present a set of specific examples & stories from our direct experience of the benefits of open collaboration to enable more productive & effective open source development.
We believe that the desire to assist each other & to collaborate is often present but unrealized. Many projects have established systems & styles of communication that limit opportunities for creative interaction, reduce flexibility, & ultimately restrict effective community engagement and results.
The session will include several hands-on exercises for participants to learn-by-doing.

PennyLane’s core feature is the ability to compute gradients of quantum circuits in a scalable way that is compatible with classical techniques such as backpropagation. PennyLane extends the automatic differentiation algorithms common in optimization and machine learning to be compatible with quantum and hybrid computations. The library provides a unified architecture for near-term quantum computing devices, supporting both discrete- and continuous-variable paradigms of quantum computation. A plugin system makes the framework compatible with any gate-based quantum simulator or hardware, including leading quantum software platforms such as Xanadu's Strawberry Fields, IBM's Qiskit, and Rigetti's PyQuil. PennyLane can be used for the optimization of variational quantum eigensolvers, quantum approximate optimization, quantum machine learning models, and many other applications.

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.
In rust's safe/unsafe model, the burden of upholding safety guarantees at the unsafe 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 unsafe logic; this issue is compounded by the fact that undefined behaviour can seep into safe rust from unsafe code that doesn't match rust's expected semantics. I'll discuss how this improves ergonomics in safe code, but requires careful engineering of unsafe code because it doesn't allow the programmer to reason locally.

It can store billions of objects in a single cluster without any disturbances. But what happens if all of your objects are "small objects"?
Because OpenStack Swift stores objects as files on XFS, disks will end-up storing millions of small files, creating large performance and stability issues. This is all related to the constraints of POSIX filesystems.
During this presentation, we will give you an overview of these issues, and explain their root causes. You will then discover what we tried to overcome them, as well as the chosen solution. Eventually, we will present you results of our production deployment.

Beneficial factors for such endeavors include the degree of interconnectedness, availability of low cost sensors, and advances in predictive analytics. This work presents a condition monitoring platform built entirely from open-source software. 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. Therefore, it combines neural network training and random forest classifier training using two different data sources. This caters for fast time-to-market and highly accurate predictions.

With the proliferation of cloud native and edge computing, we need to think about how to evolve these tools to meet the requirements of emerging and future use cases. In this talk, we will give an outlook on how the OPNFV test tool ecosystem can address new use cases and challenges. The test tools in OPNFV are not just for NFV, but can be more widely useful. We will present the tools, and discuss how they can be extended to support new and existing usecases.
This talk is aimed at an audience that want to test their SDN/NFV deloyments (but not necessarily using OPNFV). It will give an overview of the test tools, and how they can be use tools for many different deployments, test different components of your system (VIM, vswitch, storage, etc.) and perform different types of testing (infrastructure verification, feature validation, stress and resiliency testing, performance benchmarking, characterization, etc.).

How realistic is it to fight for a free and decentralized internet if only an elite of technicians have the skill, knowledge and time to administrate and maintain servers ?
Since a few years, the intention of those projects is to solve this key issue by lowering the technical barrier of self-hosting and making it a common practice. YunoHost is a Debian-based distribution that provides a clean and simple web interface through which the administrator can deploy services and apps quickly and with limited technical knowledge. The Internet Cube is a low-cost ARM board, preinstalled with YunoHost and preconfigured with a VPN to bypass ISP's restrictions, making it a plug-and-play solution for people willing to start self-hosting.
In this talk, I want to emphasize the necessity to democratize self-hosting against the GAFAM hegemony. Then, I shall recap how YunoHost and the Internet Cube currently works and present the evolution of the projects over the last two years. I will conclude by making a call for feedback and contributors from the FOSS community.

However, this pattern was traditionally coupled with object-oriented programming. In the talk, I will show how to reinvent MVC pattern, and structure your web application in a functional language - F#.
The talk will cover some brief introduction to F# - modern functional programming language running on .Net platform, show how to model MVC layers using functional composition, and at the end show some examples of applying MVC pattern with Saturn - opinionated, web development framework for F# which implements the server-side, functional MVC pattern

Both physical (myrockshotbackup) and logical (mysqldump) backups will be covered, and physical backups will be more focused.MyRocks (and RocksDB)'s physical backups basically work by 1. invoking RocksDB checkpoint that creates hard links then 2. copying data files (SST), redo logs (WAL) and others. myrockshotbackup has additional features like "renewing checkpoint" that makes replication catchup shorter, streaming backups, and auto-detecting O_DIRECT. Logical backups in MyRocks/RocksDB is more efficient than InnoDB because RocksDB more efficiently keeps track of transaction histories.How physical/logical MyRocks/RocksDB backups work are not widely discussed in public, and the speaker will demystify in this session.

Because of this, a JITcompiler's activities may hinder application throughput and createperformance hiccups that can affect quality of service while alsocomplicating resource provisioning. On top of that, it takes a while evenfor the best JIT compilers to fully compile the performance criticalmethods of an application to deliver the steady state performance we allexpect from the JVM. An approach we are exploring is to decouple the JITcompiler from the rest of the JVM so that JIT compilation can operate as aseparate, remote service. This approach opens up the possibility of anelastic, cloud based service offering JIT compilation for manyapplications, languages, and even different architectures simultaneously.
In this talk we will present our experience building an open sourceJIT-as-a-service prototype based on the Eclipse OpenJ9 JVM. We will discusssome of the engineering challenges we encountered, demonstrate theadvantages we've seen thus far, and present performance data for enterprisegrade Java EE benchmarks.

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.
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.

DESCRIPTION:Traditional NFVi dataplane performance testing rarely focuses on (availability, consumption) dark resources such as CPU Cache and Memory Bandwidth. Much of the Quality of Service fine tuning often leads to oversubscription ending up with shared resource contention often termed as noisy neighbor effects. We present the methodology and test scenarios using open source solutions - OPNFV-VSPERF Framework, Collectd monitoring solution, Stress-NG workload generator and Resource Management client for (a) analyzing the performance impact due to presence of noisy neighbors and (b) controlling resources like Last Level Cache (LLC) for optimal performance.

What might not be obvious to them is the amount of investment in the managed code’s Virtual Machine to enable both productivity and high performance. Microsoft’s .NET team would like to share how they designed the runtime environment to balance convenience, fast startup, serviceability, low latency, high throughput. For examples services such as JIT compilation, TypeSystem, garbage collection all provide convenience but come at a cost. The challenges presented are common to many environments – you do not need to be a .NET developer to attend this talk.
If you are a .NET developer, you can leverage the tools demo in this talk to tune your application as well.

It supports Secure Boot which is signature verification of bootloaders and OS kernels which helps prevent attacks where malware injects itself into the bootloader or kernel so that it can be loaded during startup. Despite the poor reputation that Secure Boot has in the free software community (mostly due to non-technical reasons), this would be useful to have for VMs running on Xen. It is also required for features in guests such as Windows Credential Guard. This talk describes how Secure Boot support has been added to Xen.

It marks the 50th anniversary of Woodstock, the beginning of America's LGBTQ movement at the Stonewall Inn in New York City, and maddog wrote his first program fifty years ago. It was also in 1969 that he shaved for the last time.
2019 marks the 30th year of the World Wide Web, the 25th anniversary of V1.0 of the Linux kernel, and of many GNU/Linux distributions starting. 2019 also marks the twentieth anniversary of the Linux Professional Institute.
All of these years, and anniversaries.....but why has Unix (and its younger offspring Linux) lasted so long? What was different about Unix that caused it to survive and flourish? Why is it important today, and how can we take it further? How should we celebrate 2019?

The advent of distributed storage environments brings in new challenges to the monitoring world. Going through logs of a large volume of data over geographically distributed nodes simultaneously to detect the point of failure is becoming infeasible and time-consuming. There is a dire need to replace the standard monitoring techniques and practices used to monitor centralized storage with a centralized monitoring system, which obtains exact information required to track the health, performance, load and capacity of system objects or software processes in the distributed systems and present it to the users in real time and in useful formats.
In this talk, Rishubh and Gowtham will discuss the challenges faced by sys-admins in monitoring distributed systems and will discuss how tendrl an open source monitoring tool aids them in monitoring a distributed storage system with the help of a scale-out open source software defined storage (SDS) - Gluster. You will get an in-depth explanation on how tendrl monitors each system in the distributed environment and get a glimpse of its modern web interface. They will also show the audience how metric virtualization provided by grafana makes monitoring rudimentary and fast. Their talk will conclude with a demo on how tendrl helps vendors in capacity planning, detecting and alerting the failure conditions, and keeping track of performance and health of the system.

However the CGEN specification in Scheme is far from rigorous by today'sstandards. Alastair Reid of ARM has shown how SAIL can be used todefine rigorous semantics for RISC-V in a paper to be presented at POPLin January 2019 (https://alastairreid.github.io/papers/POPL_19/).
In this talk I shall show how a SAIL specification can be transformedinto a CGEN framework. Using this approach, a rigorous SAIL semanticspecification can be used to generate a practical GNU assembler,disassembler and simulator.
This will is a work in progress - the project is not due to finish untilMay 2019. I shall explore the general approach used, and the areas wherethe greater rigour of SAIL runs into problems with the limitations ofCGEN Scheme specification.

We will start with an overview of what it can do, what it is made for, then we will see how to use it on a typical use case: setting up a stress test between several NIC ports with pcap dumps of real traffic.Finally, we will talk about how it was designed, how it should evolve, and what features we would like to add.

How doyou know your choice is up to snuff? The AdoptOpenJDK Quality Kit is anopen and transparent verification story for OpenJDK binaries. A robust andadaptable test kit that can be utilized by any OpenJDK implementor, andrepresents the quality bar required by large-scale customers in enterpriseenvironments. We test multiple freely available JDK implementations atAdoptOpenJDK and continue to refine this suite of tests to give thecommunity access to high-quality binaries.
Beyond a frank discussion starter on the criteria by which we measurequality, this talk summarizes the real quality requirements of enterprisecustomers and presents a compelling story for verifying and/or selectingyour OpenJDK implementation.

We will present the usage of two tools. First, the library libossia (https://github.com/OSSIA/libossia), which allows exposure and control of the parameters of a creative software over the network across many different languages and environments (C++, Java, C#, PureData, Python, SuperCollider, Qt/QML, Faust...).Then, we will show and teach the usage of the software ossia score (https://github.com/OSSIA/score), which allows to score the parameters of these creative applications in time, as well as include media, sound effects, hardware peripherals, robots, DMX lightning, etc. In particular, the interactive features, which allow for non-interactive timelines and scoring will be showcased and explained.
The OSCQuery protocol will be discussed (https://github.com/Vidvox/OSCQueryProposal). It has been conceived in collaboration with the authors of multiple industrial-grade media software companies such as VDMX, Vezér, Millumin and others. This protocol is implemented in libossia and allows extensive interoperability amongst this kind of software, in particular between websites and traditional desktop software thanks to the use of WebSockets.

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. SoftNIC allows the application to be incognizant of the hardware available to it without compromising functionality.

The hardships come of course from the embedded environment which differ in many ways compared to desktop or server Linux installations, where you must handle poor mobile network connectivity, sudden power-loss and never leave a device in a unusable state (brick) when doing the update OTA.
There are a lot of examples that have gotten attention in media, where unstable software update solutions have caused real-life problems which could have been mitigated by a robust software solution that is able to handle the corner cases that exist in the embedded environment.
In this talk Mirza Krak will present Mender, Apache 2.0 licensed end-to-end software update solution. This is a deep-dive session that will cover:

During this presentation I will give a brief overview of Buildroot and how it compares to Yocto for those in the audience who are unfamiliar with these systems. In the main part of the talk I will look at the issues relating to the implementation of RISC-V support, based on my experiences. This will include a look at the status of the RISC-V software ecosystem with regard to the selection of a suitable toolchain, C library, kernel and bootloader. I will then run through how to configure and build a minimal system for booting under QEMU. Finally I will consider any further work required to improve Buildroot for RISC-V including the status of 32-bit support.

One pessimal test case used over 80GiB. This talk will discuss techniques that were used to reduce that memory usage to less the 2GiB. This reduction was achieved through a combination of optimizing existing data structures, use of more compact data structures, and improved memory management. Use of tools such as Valgrind and pahole will be covered.

In recent headlines, there are increasing news about cloud resources getting hacked caused by attacks on Kubernetes clusters. Failing to properly secure your Kubernetes data can result in cloud resources getting hacked and your application secrets getting stolen. The etcd database contains information that may grant an attacker significant visibility into the state of your cluster.
This presentation focuses on how a gRPC-based implementation was added to Kubernetes to delegate encrypting secrets to an external Key Management Service and the benefits of using a gRPC-based design for this type of problem. Basic knowledge of Kubernetes and gRPC is a plus but not required.

It's organized as a shared-effort, shared-ownership open-source project that includes (so far) the crosvm, Kata Containers, and Firecracker teams . We believe that Rust is a great fit for a vmm: its memory management guarantees simplify the task of security hardening, while its roots as a system programming language ensure C-like performance. So far, we've started with the initial KVM wrapper crate, and, while separating out a few more basic functionality crates is underway, we still have to answer questions like "can independent teams compose reliable yet different vmms out of a set of decoupled components?", "how much can be decoupled?", "what's the right way to import/build these components into the larger vmm projects?", or, "does the world even need that many vmms?". During this talk, we'll look at some ways to answer these questions, but we're really here to get the room's feedback and opinions!

The device DMA registers are programmed by the guest with guest physical addresses (GPAs) and the virtualizer uses a physical IOMMU to map the GPAs to the actual host physical addresses (HPAs) backing the virtual machine RAM space. The physical IOMMU guarantees the DMA transfers initiated by the guest are properly translated and isolated.
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.
Some IOMMU architectures implement nested paging, including the ARM SMMUv3. This talk aims to describe the work recently done to set up the two translation stages at the Linux and QEMU levels. This integration allows a guest exposed with a virtual SMMUv3 to get the full benefit of the underlying physical SMMUv3, avoiding the need to implement shadow page tables.
The principles of the integration will be explained and the APIs will be covered. IOMMU nested paging will be compared with the existing virtual Intel IOMMU integration relying on shadow page tables. Remaining challenges will be presented.

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.
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.

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.
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.
