Monitoring can mean very different things to different people, and this often leads to confusion and misunderstandings. There are many offerings both free software and commercials, and it's not always clear where each fits in the bigger picture. This talk will look a bit at the history of monitoring, and then into the general categories of Metrics, Logs, Profiling and Distributed tracing and how each of these is important in Cloud-based environment.

The secrecy around it is of the utmost importance in order to prevent the original creations from being stolen. The different stages of the process and the techniques used are only known by those involved in the design.How could we call this stance into question and open the creative process?This talk will present existing initiatives and thoughts to make Graphic Design and Open Fonts fields more available to the public.

More often than not, they want to re-write their favourite game, but making it a little easier! Unfortunately the gap between a personal project, open source game, and professional offering is substantial, with the lack of polish obvious at every turn. In this talk, Steven Goodwin, a game developer of 20 years standing (and 3 books on the subject), dissects each discipline (art, music, writing, and code) to explain where polish should be added and why it’s so rare to see open source games as effective as their commercial counterparts.

You will learn how to use the combination of chroot, Linux::Unshare and Linux::Prctl to create simple yet powerful isolation for your applications. Finally you will also see how to enter in LXC/Docker containers without resorting to external applications. The main goal is to show you the steps you have to follow in order to make sure you build a good isolation.

To facilitate file selection and (automated) downloads, I developed an R package that can be used to select, download, read and process weather data. The aim of the package is that researchers can focus on scientific problems instead of data management. At FOSDEM, I would like to present the main instructions for the package, how the FOSS community aided in putting it together, and give a brief outlook on the potential analysis types.The package is FOSS at https://github.com/brry/rdwd#rdwd

The decision of creating a jobs board as part of the Open Source Design project was no doubt an excellent one. Our conversations during the first Open Source Design devroom showed that a place to match designers with FOSS projects was sorely needed. At November 19th, the jobs board has received 53 submissions. I consider this a success, given our limited reach and the small size of the Open Source Design initiative.
Going through the content of those 53 submissions shows a clear pattern: the overwhelming majority are looking for graphic designers, and many of them are asking for a project logo.

But when it comes to multi-container applications, most production setups use advanced container orchestration technologies like Kubernetes, Openshift, Mesos/Marathon, which are not that developer friendly.
Developers prefer docker-compose for its simplicity. This talk will showcase our ongoing efforts at Red Hat, Skippbox and Google to bridge this gap between deploying containers in development to production, and the need to standardize a multiple container definition spec which works seamlessly across different environments and container orchestration platforms.

Then test cases are executed against each mutant. This helps answer the question "How good is our test suite?". For example if we have made the following change:
- if A and B:+ if A or B:and our test suite reports a PASS result that means we are not doing a good job at detecting possible errors.
I have been using mutation testing for production grade software in both Python and Ruby and I'm also the most active contributor to Cosmic Ray, the mutation testing tool for Python. In this talk I will explain how mutation testing works and what it can be used for. I will give practical examples of code which wasn't tested and how to test it and also examples of bugs that I've found. I will also mention some differences between the Python and Ruby tools.

However they often seem to misunderstand what the software designers want, and deliver something that makes their life harder without any apparent benefit.
In this talk Luca will share some of his experiences with such vendor BSPs, featuring jurassic kernels, non-working drivers, non-existing bootloaders, code of appallingly bad quality, ineffective customer support and Windows-only tools.
You will discover why he spent weeks in understanding, fixing and working around BSPs instead of just using them. The effects on the final product quality will be described as well.
Luca will also discuss what the options are when you face such a BSP, and what both hackers and vendors can do to improve the situation for everybody's benefit.

The plugin extends the options for the LeafletJS Standard API elements Marker, CircleMarker, Popup, ImageOverlay and GeoJSON so you can publish these map elements in HTML semantically annotated ‐ and therewith machine readable web maps. While there is quite some effort already around the development of new geospatial data catalogs (which are awesome) this plugin turns the focus onto geographic web maps. Acknowleding that, de-facto, some maps already are data catalogs themselves, they are just not that well represented in HTML so that other programs can extract and re-use the information people collect in them.

I want to learn Perl 6 myself, and I also want to create material that can be used to raise passion for the language when it's used as a first(ish) language. So I have convinced my daughters to create a study group where I will prepare materials and follow a project-based and design-thinking approach to learn Perl 6. My intention is also to find the way towards a more gender-balanced, inclusive community and test new ways of learning computer programs by eating my own dog food (as presented in other conferences).
During the talk, which will be a dialogue, and maybe staged as a play, we will present our experience, what we have learned from it, what we haven't learned from it (hope Perl 6 is not in this category) and how others might benefit from it. I am uploading the material to http://github.com/JJ/perl6em, where you can see it's still a work in progress.

In particular for one of the core data categories in science and engineering, massive multi-dimensional arrays, out-of-memory solutions typically employ their own, different models.
We discuss this situation on the example of the scalable open-source array engine, rasdaman ("raster data manager") which offers access to and processing of Petascale multi-dimensional arrays through an SQL-style array query language, rasql. Such queries are executed in the server on a storage engine utilizing adaptive array partitioning and based on a processing engine implementing a "tile streaming" paradigm to allow processing of arrays massively larger than server RAM. The rasdaman QL has acted as blueprint for forthcoming ISO Array SQL and the Open Geospatial Consortium (OGC) geo analytics language, Web Coverage Processing Service, adopted in 2008. Not surprisingly, rasdaman is OGC and INSPIRE Reference Implementation for their "Big Earth Data" standards suite.
Recently, rasdaman has been augmented with a python interface which allows to transparently interact with the database (credits go to Siddharth Shukla's Master Thesis at Jacobs University). Programmers do not need to know the rasdaman query language, as the operators are silently transformed, through lazy evaluation, into queries.

Wt provides widget-centric API to write web application as if graphical application. Wt translates this to Ajax powered site or to plain HTML site depending on the client. Unlike page-based frameworks or single-page JavaScript frameworks, Wt creates stateful applications that are at the same time highly interactive but still support plain HTML browsers or web crawlers.
Luawt uses all the power of Wt in the world of Lua. Luawt is different from popular solutions like Lapis and Sailor, because Wt is different. Target customer of luawt wants to provide web interface to a library, written in C or Lua. Luawt application can’t run directly from nginx.conf, but the application has per-session state and its code looks like GUI application's code. Luawt is not finished yet, but we have a number of solutions to automate generation of bindings using gccxml, so we expect it to become a practical solution very soon.
We would like to give a talk about luawt in order to show its facilities and demonstrate several examples how it could be applied in everyday web development.
Homepage of luawt: https://github.com/LuaAndC/luawtLuawt is delivered to you by Pavel Dolgov (github.com/zer0main) who is a CS student and open source developer and Boris Nagaev (github.com/starius) who is a site reliability engineer.

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

It's also interoperable between multiple languages.
But beyond that fact that it's more efficient than REST, we'll look into how to use gRPC's streaming API, where you can establish server-side streaming, client-side streaming, and bidirectional streaming! This allows developers to build sophisticated real-time applications with ease.
In addition to learning about gRPC and HTTP/2 concepts with code and demonstrations, we'll also deep dive into integration with existing build systems such as Maven and Gralde, but also frameworks such as Spring Boot and RxJava. - Configuring projects to generate gRPC stub code - Using Protobuf3 to define services - Creating synchronous and asynchronous services, with streaming. - Load balancing - Interceptors

And lately, it’s also been used for tracing microservice-based transactions too.
These are really useful capabilities, but what if you could profile everything? Yes everything - software functions, microservice calls, file access, network requests, even bash scripts. How would this change your view on your systems? How would this enable you to better understand what your software is actually doing?
In this talk I’ll show you how to trace everything using open source sysdig. We’ll cover:- How to trace everything from a method in your software, a service call, a network request, a shell command execution, a script, and more- How to report on your traces to make the most sense of the data- Use real-world examples of tracing that show its benefits

DESCRIPTION:Conflict sucks! The free software community is full of passionate people with many, many differing ideas on how to achieve our shared goals. Disagreements seem inevitable, but what if they could be handled rationally, in a way that left everyone feeling at least OK about the outcome? It's possible. You can learn to cut to the heart of the disagreement, mediate and move forward.
Many of us avoid dealing with tricky situations or let conflict avoidance keep us from accomplishing amazing things together. Conflict can be handled -- without flamethrowers -- and the process will often make your community stronger. It just takes time, a slightly relaxed ego and a willingness to see the best outcome for the most people. This talk covers when to handle conflict, strategies for both one-on-one situations and group situations and tips on how to scale your conflict resolution skills, like a boss.

It remarkably raised testing versatility and provided a high flexibility to users and developers. But supporting the Genode API on self-contained third-party kernels is sometimes also accompanied with deficiencies, redundancies, or work-arounds. To also have the option of a basic kernel without such compromises, the custom Genode kernel was developed. Its main distinguishing mark may be that it not only trusts the Genode Core-component but even more is a mere library to it. The implications of this new design and other characteristics of the custom Genode kernel, such as scheduling, capabilities, and ARM virtualization, are discussed in this lecture.

Most of the people building open source software are engineers with major turn on for features and more features which kind of explains how a lot of open source projects have rich and extremely important features but are a pain to see or work with. This talk aims to deal with this problem of designing in the open which is often neglected. Tools like GitHub, GitLab, etc. can actually become an arena for usability testing and give extremely promising output only if it follows an effective design process. This talk is also a practical guide for budding designers to get started with open source software.

DESCRIPTION:Clouds are spreading and software is eating the world. But software depends on hardware. If that hardware is not trustworthy, open and secure, the software's trustworthiness, openness and security is for naught. The Free Software community has been forced to live with this conundrum for lack of good alternatives. Too pervasive and omnipresent was the Intel defined x86 architecture, throttling innovation, while sequestering security and control from its users.
Most of the discussion in our community centred around damage control and preventing being locked out from the platform for good. We focused our efforts on protecting our ability to use our own software. Positively shaping the future, driving the direction, and solving the problem of trustworthy hardware for good and at scale seemed impossible.
But, the thing is, without (almost) anybody noticing, all of the above has changed.

Thanks to "mido" and "portmidi" libraries, I designed a lightweight open source software sequencer (without a GUI), exposing abstractions for python programmers to use their existing MIDI-enabled hardware. My MiniNova, Launch Control and Quneo devices were hacked this way to create new functionality together.
The talk starts with a quick explanation of MIDI and step sequencing, then describes the benefits and challenges of using Python in this context, as well as the choice of gevent against other async frameworks. It ends of course with a live demo!

Interestingly enough the firmware is available under (3 clause) BSD license and thus open for hacking, abusing and modifying to your needs.
We’ll look at a bunch of MCU options and eval boards to get started with, their availability and pricing in low quantities as well as ways to hook them up to your embedded platform. Moreover we’ll look at hardware level requirements your SoC / board will have to provide in order to make it all work.
We’ll cover existing driver / software support in upstream Linux and U-Boot, as well as parts that are or were missing.
Typical tasks of an embedded controller for a chromebook or random other devices like mine - which is everything but a laptop - will be discussed. Topics covered will include boot selection, firmware upgrades, watchdog timers and others.
Finally I’ll share my experiences building a real world Zynq based system using chromium-ec on an STM32 MCU and my experiences adapting the software to my needs and interacting with the community.Examples include replacing the coreboot bootflow with U-Boot, creating device drivers for things like buttons and issues encountered in making things work.

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

Back then everybody could set up his own web server, mail server or news server and communicate with the rest of the world. The last years we saw, that for many users the internet was reduced to a few centralized services used to connect with their friends, to communicate and to store and share all kind of data. Nextcloud wants counteract this development for people who want to store, sync and share their data. It provides a cloud platform based on Open Standards and Free Software. To connect the nodes of self-hosted cloud platforms, Nextcloud is the driving force behind the concept of Cloud Federation. The aim is to provide a Open Standard to share data across multiple cloud servers. At the moment this protocol is not only implemented by Nextcloud but also by Pydio and ownCloud. Together with many partners, Nextcloud works on formalizing the protocols to create a real standard. This talk want to discuss how to restore a free, decentralized and open internet in the area of data sync and share.

We will show how to combine free software tools and protocols from the worlds of IT monitoring, Industrial control and IoT to create simple yet robust dashboards.
Modbus [1] is a serial communication protocol developed in 1979 for use with programmable logic controllers (PLCs). In simple terms, it is a method used for transmitting information over serial lines between electronic devices., it’s openly published, royalty-free, simple and robust.
Many industrial controllers can speak Modbus, we can also teach “hobby” devices like Arduino boards and ESP8266 to speak Modbus [2]. Reliable, robust and simple free software Modbus client [3] will be used to acquire the metrics from our device, then the metrics will be collected [6][7] and sent to Hawkular and Grafana [8] to store and visualize our data.

The process of investigation should have as small influence as possible on the server we try to troubleshoot. Ideally, the source code should be instrumented for that.
Performance_schema introduced in MySQL 5.5 is supposed to provide detailed enough instrumentation. But it comes with a cost, require careful sizing of performance counters, and the process of instrumenting the code is not yet complete even for MySQL itself, to say nothing about 3rd party storage engines, plugins and libraries like Galera.
This is when profilers come handy. Poor Man's Profiler (PMP, aka pt-pmp), perf and oprofile on Linux can be easily used while studying MySQL performance problems. Basic usage steps are presented and several typical use cases are discussed.

A significant performance penalty is incurred for every additional table that needs to be joined for a query. That is why SQL databases are notoriously bad at deducting relationships from datasets. Graph databases however are really good at this task. In this talk we discuss potential application areas of graph databases in existing open source CMSs like Drupal.

But with increasing scope, the number of frequently used functions grows to an extent that can have a detrimental impact on quickly locating a particular item. LibreOffice made it possible to create UI based toolbars on blank canvas where designers have all the freedom to do whatever they want with the space. The talk will present the reasoning behind the Notebookbar layout with contextual groups.

From most perspectives, from Clang through to code generation, the size of most operations do not make much difference to the ease of implementation. However there are some assumptions that are baked deeply into the compiler; one of which is the memory access width, more specifically that it is addressible in 8-bit words. This however is not always the case, many embedded DSPs can only access memory with 16-bit addressibility, and trying to teach LLVM about this proves to be a challenge.
In this talk, we will present our first explorations in this area, and share our thoughts on how we can make LLVM more memory agnostic for all targets with non-8-bit memory.

As scientists weoften do not get root access which means that we either depend on whatsoftware is available or we build software in a dedicated directoryusing tools such as Brew, Conda or even from source. Unfortunatelythese solutions depend on already installed tools from an underlyingdistribution, often proprietary or dated compilers, and, for example,modules. Any binary that gets produced, therefore, tends to be totallyunique, both in the generated binary and its set of dependencies. Thisis bad, both for trouble shooting and for pursuing reproduciblescience. With GNU Guix we are developing a fully reproducible free softwarestack including all dependencies targeting cross-builds forheterogeneous computing environments, such as the Beacon IntelPHI-based supercomputer, without having a requirement forcontainers. In this talk I will describe the challenges we areovercoming and what it will mean for the HPC community to havearchitecture optimized and fully reproducible build targets that canbe deployed in a non-root, non-container environment.

While Xen supports live migration of VMs which mitigates the need for live patching, there are still some reasons why live patching is useful. For example, to minimize downtime, when running applications with low latency requirements, and when using PCI passthrough.
This talk reviews the state of live patching for Xen. A live patching implementation has recently been contributed to Xen so we will look at the design and implementation in detail, noting how and why it differs from live patching for Linux. We will look at some of the ways that live patches can be created and the pitfalls to watch out for when doing so. There will also be a status report of ongoing and future work for live patching for Xen. Finally, the talk will show a demo of live patching in action by building a live patch for a known security issue and applying it to a vulnerable system.

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

It decomposes key operating system functionality such as file systems, networking, device drivers and graphical user interface into a collection of fine-grained user space components that interact with each other via message passing. HelenOS does not aim to be a clone of any existing operating system and trades compatibility with legacy APIs for cleaner design. Most of HelenOS components have been made to order specifically for HelenOS so that its essential parts can stay free of glue code, franken-components and the maintenance burden incurred by them. In this talk I will do the annual HelenOS project update.

Informal DSLs arise from particular communities, evolve over time and often lack formal specifications. Examples include: templating languages, micro web frameworks, and various wiki markup languages. Perl 6 provides a number of mechanisms for parsing and interpreting such informal DSLs, including custom operators, grammars, and slangs. In this talk, we examine these mechanisms and demonstrate how they can be applied to specific DSLs.

Given our current technology, that would be magic. The lack of wizarding skills did not stop us, however, from tackling the problem by using smart caching structures, which are witchcrafts on their own.
Why is this challenge important? Several applications evaluate global queries on continuously changing graphs: fraud detection in financial transactions, analysis of source code repositories and validating engineering models. Current approaches employ domain-specific optimizations, which are difficult and error-prone to implement. Meanwhile, the requirements of these (and similar) use cases could be uniformly addressed by incremental graph query evaluation. With this technique, the first execution of the queries takes some time, but once the result are calculated, they can be efficiently maintained for each change in the graph.
To allow incremental queries on property graphs, we implemented the ingraph engine, based on the openCypher language specification. We aim to support the standard subset of openCypher, as most standard constructs can be calculated incrementally. We already mapped some of the standard constructs to relational algebra, defined incremental relational algebraic operators and implemented them in an incremental relational engine using Akka actors.
We start the talk by presenting use cases that evaluate complex global queries on continuously changing graphs and discuss the idea of incremental graph queries. We show the mapping of basic openCypher constructs (e.g. MATCH, WHERE, WITH, RETURN) to relational operators, such as joins, selections and projections. Finally, we show our approach for optimizing incremental graph queries and outline related challenges.
Target audience: Developers, looking for a deeper understanding of openCypher and/or facing complex queries on continuously changing graphs

This talk evaluates the use cases and benefits of NVMe drives for its use in Big Data clusters with HBase and Hadoop HDFS.
First, we benchmark the different drives using system level tools (FIO) to get maximum expected values for each different device type and set expectations.Second, we explore the different options and use cases of HBase storage and benchmark the different setups.And finally, we evaluate the speedups obtained by the NVMe technology for the different Big Data use cases from the YCSB benchmark.
In summary, while the NVMe drives show up to 8x speedup in best case scenarios, testing the cost-efficiency of new device technologies is not straightforward in Big Data, where we need to overcome system level caching to measure the maximum benefits.

With CloudABI, we're trying to make this process a lot easier.
CloudABI is a blend of POSIX and pure capability-based security, which allows you to create applications that are only capable of accessing those things that they are designed to use. As you'll see, software also becomes easier to test and deploy as a result of using this model.

Is it better to use INTEGER or BIGINT, and should you use TIMESTAMP or is it better to use TIMESTAMPTZ? When is the last time you migrated a legacy database and wondered what to use as replacement for VARCHAR2 or CHAR(255)? How to store IP addresses or geographical data, does that fit into VARCHAR or is there something more suitable?
PostgreSQL 9.6 comes with around 40 different data types preinstalled. This talk looks beyond INTEGER and VARCHAR and dives into some of the lesser known PostgreSQL data types. Use cases and examples show which data type is a good fit for a certain situation.

TCP and UDP socket based applications are core technologies in the modern data-center. The introduction of Orchestration, SDN controllers, vSwitches and Virtual Dataplane have seen a huge change in how network packets are delivered to data-centre nodes. While the stacks that consume these packets, the socket based applications have evolved much more slowly. Virtual switches like VPP and OVS-DPDK, have benefited from the vector packet processing technology in DPDK to scale process millions of packets per second, while TCP and UDP socket based applications have not yet benefited. There have been a number recent efforts to port various L4 implementations to DPDK, and while these usually give a modest performance benefit the performance of these is not yet revolutionary.
TLDK has been developed from the ground up to be a very fast and scalable UDP and TCP implementation, targeted for use with DPDK and VPP. In this presentation will provide an overview of TLDK design and implementation. This deep-dive will include:-
Working with time is not a trivial challenge. Python includes a native module in the standard library to work with it but datetime keeps being together with unicode a common source of errors. This often leads to the widespread of many other libraries in the attempt of easing the work of working with datetime. Datetime is one of those API that looks easy to use but given the many concepts around time, is it easy to get backfired if the developer has not solid knowledge about the them.
In this talk we will overview the main concepts about timestamps represented through datetime objects, the limitations on the standard library and some simple steps to try to avoid the common mistakes that everyone can fall into.
Naive datetimes (which the datetime API works by default with) are a great tool to represent calendar times, but when talking about timestamps (focus of this talk) timezones is n essential part of it and the datetime module can be tricky to use for that use cases.
We will also speak about different standards of time, time zones, Daylight Saving Times, leap seconds, serialization and datetime arithmetics.
The talk will be focused on giving the foundations that everyone knows to be able to understand and work efficiently and without making painful mistakes when dealing with time related algorithms.

It has served HPC support teams well on standard Linux/x86 systems since 2012.
More recently, interest has grown to also employ EasyBuild on Cray systems, where the Cray Programming Environment (PE) not only provides common tools (compilers, ...) and libraries (MPI, BLAS/LAPACK, FFTW, ...), but also tuned installations of 3rd party libraries like HDF5, netCDF and PETSc. The Cray PE consists of an extensive stack of environment modules, providing a familiar yet complex working environment of users.
To leverage the Cray PE a couple of enhancements had to be made to EasyBuild, including support for using 'external' modules, and defining Cray-specific compiler toolchains. In addition, the way in which EasyBuild deals with environment modules had to be carefully revisited, since standard operations like 'module purge' are not supported by the Cray PE.
This work has led to the use of EasyBuild in production on the largest Cray supercomputer in Europe, the Piz Daint system at the Swiss National Supercomputing Centre.
In this talk, we will outline how Cray systems are different from standard HPC systems, motivate the need for a tool like EasyBuild despite the presence of Cray PE, and show how EasyBuild was tweaked to support reproducible software installations on Cray systems.
We believe this is interesting success story of how FOSS has significantly enhanced the software environment on a multi-million dollar production system.

Ideally one which works perfectly after the first tapeout. Tailored towards this goal are our development and testing processes: strictly following a V-model with separated development and verification teams, long design iterations and code which, once it's known to work, is never touched again. For people coming from the software world, this development approach looks arcane. Where are all the sprints, the agile methods, the quick iterations?
With FPGAs being on the rise and available in more and more cloud data centers and possibly bundled with our next Intel processor, we finally get the chance to cheaply make mistakes in digital hardware designs: no more wasted tapeouts, just a new flashing of the FPGA is necessary to fix a bug.
Join me in this talk for a look at development processes and tools. Where can we build bridges between the software and hardware development world, and where do we have fundamentally different needs?

These operations create or remove volumes, copy data between volumes, create or merge snapshots, and various other actions related to virtual machine storage. For efficiency and balance these operations should be distributed across multiple hosts and run in parallel when possible. Maintaining reliability under real world conditions requires careful management and resilient algorithms. This talk will introduce some of the problems that can arise including: dropped communications, scheduling conflicts, and host or storage array failure. Next, a solution to these problems using shared storage locking, atomic operations, volume generations, and forensic analysis of the storage will be presented. Through step by step examples, the audience will understand how the proposed solution can solve all of the outlined problems.

LoRaWAN is a Low Power Wide Area Network (LPWAN) specification intended for wireless battery operated Things in regional, national or global networks. LoRaWAN target key requirements of Internet of Things such as secure bi-directional communication, mobility and localization services.
In this talk, I will introduce LoRaWAN as a key radio technology for IoT and walk through why it is a technologically important development as I show how to build LoRaWAN node applications to explore the possibility of IoT. There are a number of LoRaWAN networks emerging across Europe and I will highlight the political importance of why these networks should be open, supporting Open Data and Open Science and empowering the development of a new set application domains.
The lecture will involve a demonstration of an LoRaWAN application that will showcase the both the node and Gateway aspects of a deployed network.

It allows creating low-cost projects using Wi-Fi and easy scripting in Lua, which makes it great for making wearables, for example. In this talk I'll give an introduction to the platform, show how I built an audio reactive graduation dress and share the materials to get you started on your own wearable project. This talk is ideal for beginners to hardware hacking or Lua enthusiasts looking for project inspiration.

In this talk, I will focus on one area of testing that is difficult to automate: poor network connectivity. Developers usually work within reliable networking conditions so they might not notice issues that arise in other networking conditions. I will explain how traffic control on Linux can help to simulate various network connectivity. I will run a demo with Weave Scope showing how an application running in Kubernetes behaves when changing network parameters.

The demand for an open IoT platform is increasing to enable and accelerate the development of cross-domain/cross-vendor use cases and face the accompanying challenges like connectivity with a wide range of heterogeneous protocols and large scale messaging. Eclipse IoT on top of Cloud Foundry is a promising software stack for this goal. However, it will only be successful if it is widely adopted. I will show you where we are today and we can find out together where to go tomorrow.

In this talk, we will describe some old and new features that help tounderstand what happens in your application.Among others, we will give a demo and/or discuss:
how to use valgrind with your application specific memory pool
how to (interactively) ask Valgrind to describe a piece of memory
some heuristics used by Valgrind to reduce the number of'possibly lost' leaks with C++ code
...
We will discuss more in detail the concept of execution trees,which will be available in the next Valgrind release.An execution tree associates stack traces of your program with some data.Execution trees allow Memcheck and Helgrind to providea memory profile of your application. We will show how such an executiontree memory profile can be visualised using tools such asMassif visualiser or kcachegrind.

DESCRIPTION:How do you integrate containers in your IaaS? In a VM based IaaS environment, introducing containers can be a painful experience. Most likely you end up running containers inside VMs to reuse existing infrastructure, or you start dividing your data-center into a container- and a VM-world. Either way, you have two management solutions and non optimal resource management. But what if we put VMs inside containers? Would such a copernican revolution give us some benefits? This talk covers our research around using Kubernetes as a virtual machines cluster manager.

This makes tracking the applications and libraries that actually get used considerably more important. Existing solutions (module load hooks, launch wrappers) do not account for user-built software, are hard to deploy or produce inconclusive results.
OGRT enables the tracking of jobs on a cluster with process-level granularity and without discernible performance penalty. It tracks used shared libraries, environment variables and loaded modules at the moment of process execution. It also supports watermarking executables and shared objects and reading those watermarks out of memory at runtime. Gathered information is collected and shipped to various backends.
OGRT aims to be a versatile tool, which can be used to:
This presentation will give an overview of the design and implementation of OGRT, as well as demoing some of its capabilities when plugged into an Elasticsearch backend.

DESCRIPTION:Thermostat is a monitoring and management tool for Java deployments,allowing users to measure and monitor a host of different performanceaspects of their Java applications. Available metrics range from rawCPU and memory usage to operation of the Garbage Collector and JITcompiler through to thread activity and method call/heap profiles.Thermostat provides a GUI view of activity of local and distributedJVMs in a live-view or, alternatively, offline for after-the-factanalysis.
What Thermostat cannot do on its own is track events and recordstatistics that are specific to a given Java application, at least notunless the application co-operates with it, for example by publishingJMX statistics that Thermostat can read, persist and display in itsGUI. However, that's about to change thanks to work Thermostatdevelopers have been doing to integrate Byteman into Thermostat.
Byteman is a tool which can be used to modify the behaviour of Javaprograms by injecting extra Java code almost anywhere in the program.You don't need to recompile your program or even prepare it in advancein order for this to work. You can specify changes to the program onthe command line but, what is more amazing, you can actually useByteman to change the way a program runs after startup while it isstill running.
In this talk we will show how Thermostat can collect and visualizemetrics with Byteman's help in order to better understand a specificperformance issue in a Java application.

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

Seamless secure (TLS) connections on the internet are underpinned by the Web PKI - a system where Certificate Authorities (CAs) issue identity certificates to people and sites, and clients such as browsers have a "trusted root" list of those they think will do that job right. Mozilla runs the only open and transparently root program, which defines what Firefox (and probably your Linux distro) trusts; this talk explains how we use that power to make the Internet a safer and more secure place.

The SPARK language is a subset of Ada and can be compiled with the GNAT toolchains to a wide range of platforms, including the popular ARM Cortex M3, M4 and M7. The SPARK language also provides specification features, so that the intended behavior of the program can be embedded in the program itself. The SPARK formal verification tool can check that a program does not contain any run-time error, such as buffer or integer overflows, and that the code complies with its specification. We will demonstrate these capabilities on a game of Tetris, whose core game logic has been proved, and which has been ported to several embedded platforms: SAM4S Xplained Pro Evaluation Kit, Pebble Time watch, Unity game engine, Arduboy game platform. We will show in particular that you don’t need any specific mathematical background to achieve such results!

I’ll be talking here about the next evolution for Pipeline that is just now hitting 1.0: a simple, declarative model to define your Pipelines with no need to write scripts. This configuration syntax for Pipeline allows you to automatically configure all stages of your pipeline, the complete build environment, post-build actions, notifications and more. All while providing syntactic and semantic validation before the build actually gets going. We'll also play with the just-released initial version of the Pipeline Editor, built to work with Declarative!

Every time a process releases the CPU, we manage to restart it from its last starting point and re-run the same portion of the process code. An practical application of this could be an implementation of a fault tolerant system. At the end of the two executions, one may compare their memory footprints to detect an eventual fault due for example to SEU. We are also interested in the performance penalty this would induce on the overall systems compared to existing redundancy models.In this talk, we will present how Genode components performances are impacted by this type of redundancy. Possible choices and remaining challenges for extending this model for multiprocessor environment will also be discussed.

I will argue that while openness and transparency are necessary, they are not sufficient. Particularly as the number of open source communities governed by trade associations grows, additional principles are necessary such as vendor neutrality, and ensuring a level playing field. This talk will provide an overview of the (often legal) control points that exist in open communities, and various strategies used by corporations to seize them. It will also provide some examples of existing community governance rules which openly and transparently ensure special rights to particular organizations. A few simple governance hacks to help make trade associations better stewards of open communities will also be discussed.

Typically, these libraries were designed for data that fits in memory and for computations that run on a single core.
Dask is a Python library for parallel and distributed computing, using blocked algorithms and task scheduling. By leveraging the existing Python data ecosystem, Dask enables to compute on arrays and dataframes that are larger than memory, while exploiting parallelism or distributed computing power, but in a familiar interface (mirroring Numpy arrays and Pandas dataframes).

One rightfully popular approach is to run the applicationas a Docker container inside a Kubernetes cluster, giving you a lot ofoperational benefits thanks to the Kubernetes folks.
For the most part it is rather easy to make your Python applicationwork inside a Docker container. But there are a number of commonpatterns one can follow to save time by delegating more things to theruntime environment. Furthermore you can start adding a few simplenon-intrusive features to your application which will help improve theapplication live-cycle in the cluster, ensuring smooth hand-over whenmigrating the container to different nodes or scaling it up or down.
This talk will discuss how to write a Python application which willbehave well in this environment, starting with the basics steps youcan rely on the runtime for, covering logging and all the way tosupporting the service life-cycle, health checking and monitoring in aKubernetes environment. You will see that building a cloud-nativeapplication is not very hard and something you can graduallyintroduce.

Often, data get discretized in space and time, naturally leading to multi-dimensional arrays. In fact, arrays play a core role in most domains of science, engineering, and business - generally speaking, spatio-temporal sensor, image, timeseries, simulation, and statistics data. This raises the need for flexible, scalable, and open services in replacement of the bespoke silo solutions that have prevailed in the past.
Traditional databases have been successful due to their flexibility (through query languages) and scalability (through manifold optimizations and parallelization in the server) - however, they unfortunately do not support massive arrays. This is being remedied within ISO currently where SQL/MDA ("Multi-Dimensional Arrays") is in an advanced stage, likely becoming adopted in summer 2017. SQL/MDA adds declarative array definition and operations to SQL. Not only paves this the way for powerful services, maybe even more important it allows, for the first time, integrating data and metadata into the same archive, even in one and the same query. As such, SQL/MDA will be a game changer in data services not only for science and engineering at large.
We present the concepts and rationales, as well as the open-source technology rasdaman ("raster data manager") which is serving as the blueprint for MDA.

However, when you wake up in the morning, things might not have gone the way you expect. This talk will be about such a surprise.
Once upon a time, a failure brought down a master. Automation kicked in and fixed things. However, a fancy failure, combined with human errors, with an edge-case recovery, and a lack of oversight in automation, lead to a split-brain. This talk will go into details about the convoluted - but still real world - sequence of events that lead to this disaster. I will cover what could have avoided the split-brain and what could have make things easier to fix it.

With Singularity, HPC users can safely bring their own execution environments to the cluster. Unlike other container solutions, Singularity does not require root level permissions to run containers, which allows users to freely control what software stack they wish to use. Provisioning of a container image can be done locally on the user's machine or on Singularity Hub. The resulting image can then be securely executed on any machine with Singularity installed. Reproduction of results has never been easier: a user can now share a single Singularity image file that will ensure a consistent execution environment wherever it is run.
This presentation will provide an in-depth look at how Singularity is able to securely run user containers on HPC systems. After a brief introduction to Singularity and its relationship to other container solutions, the details of Singularity's runtime will be explored. The way that Singularity leverages Linux features such as namespaces, bind mounts, and SUID binaries will be discussed in further detail as well.

It can manipulate everything in your document, spreadsheets and slides. It helps you to create complicated reports automatically. But OpenOffice Basic is not cool. It lacks everything a modern hardcore developer needs: Personal favorite text editors, version controls, source repositories, etc. OpenOffice Basic macros are created and edited only with Basic IDE, and stored in some hidden place in your hard disk, not in the source form but in XML. They cannot be managed with modern development tools like svn, git, different text editors, and cloud storage backup.
What if there is a tool that let you work off-line, out of the OpenOffice Basic IDE box, with your favorite text editor, on anywhere on your hard drive? That's why I wrote obasync to do this job: Synchronize your local Basic macro sources with OpenOffice Basic storage. It frees me from Basic IDE and I can apply every source code development tools now.

That’s why we created Sysdig Falco, the open source behavioral activity monitor for containerized environments.
Sysdig Falco can detect and alert on anomalous behavior at the application, file, system, and network level. In this session get a deep dive into Falco:- How does behavioral security differ from existing security solutions like image scanning?- How does Falco work?- What can it detect? Building and customizing rules- Next steps

To better understand how it is being developed, a software development analytics dashboard has been deployed for it. This dashboard tracks most of the public data about Rust development, and allows to visualize, drill down and understand that data. The talk will present this dashboard, and how to use it to learn about the details of Rust development processes and community. It will also present some interesting data obtained from it.

This inserts some compile and runtime buffer overflow checks for selected glibc functions. These checks have no or very little runtime overhead and work on the object level (the compiler provides/proofs the size of the object buffer size). valgrind memcheck provides similar memory buffer overflow checks. These checks don't need any compiler help (you won't have to rebuild your code). But they have a much higher runtime overhead. They also work on a different level. valgrind memcheck doesn't know anything about the objects the user is manipulation but has knowledge of all memory blocks allocated. Lets explore how these different mechanisms work and how we can make them work better together.

Of particular focus are the language tradeoffs necessary to ensure the ability to efficiently generate high-performance GPU code from a high-level parallel language. We also demonstrate (nested) data-parallel array programming, a programming paradigm that enables concise programming of massively parallel systems. We show how Futhark code can be easily integrated with larger applications written in other language. Finally, we report benchmarks showing that Futhark is able to match the performance of hand-written code on various published benchmarks.

DESCRIPTION:The world is not perfect and network failures do happen. Complaining about instability might not always be enough. Especially when your system depends on multiple networked services and each of them is on a critical path to the final result.
This talk will follow a real story of an attempt to implement network errors handling by retries functionality that is inside urllib3 and requests Python libraries. More importantly we will simulate poor network conditions on a local machine using Linux Network Emulator and then will reason on how effective the attempt was and what can be further improved.
This is a proper treatment the networked systems should get when they are designed, developed and tested. And it is great that all the tools necessary are already there in most popular Linux distributions.

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

DESCRIPTION:When Free and Open Source Software (FOSS) are becoming more broadly deployed (sometimes as part of proprietary systems) amongst organisations who have limited pre-understanding of the philosophy underlying FOSS there are a number of challenges which need to be successfully addressed. Such challenges include licensing obligations for FOSS and a number of associated legal issues, such as patents, trademarks, procurement law, and various conditions (e.g. FRAND-terms) for use of standards. Many companies and public sector organisations struggle with these challenges and there are sometimes tensions and legal disputes between different interests, which may involve organisations and individuals contributing to specific open source projects.
This panel seeks to address the following overarching question:Which are the contemporary legal and policy challenges needed to be better understood through systematic research studies, and what relevant studies should be designed and conducted in order to produce relevant research results as well as practical outcomes in order to shed light on these challenges?
The (45 minutes) panel will start with short position statements by the panellists and a dialogue between them. Significant time will be allocated to an open discussion on the issues with the audience, and those attending are invited to raise their own concerns and share their own experiences.

We've implemented most ideas since, and we're happy to see thatour ideas work out in practice: quite often, understanding the rootcause for a performance regression now takes about 5 to 10 minutes ofwork, whereas before it typically took us half a day to produce alldata that is now recorded automatically.
I intend to give a demo of how we use LNT at ARM's LLVM teams. I'llalso discuss how LNT is useful for other projects that need to trackperformance of generated code. LNT is starting to be used by at leastalso some GCC, java jit and even a Verilog-to-C++ compiler teams.
I'll also give the necessary pointers on what you need to getstarted on LNT for your own projects.

This allows developers on all platforms to use their preferred environment and still IDE features like code-completion on many of them without the need to manually maintain all of those. Gbuild, the LibreOffice build system, exports most relevant data about this to JSON files, which then can be used to create project solutions on multiple IDEs. This talk describes how we got there, past and future challenges and opportunities. It might also be of interest for other projects interested in providing something similar.

However, it is primarily supported by graph database systems such as Neo4j but, besides research prototypes, not generally available for distributed (not-only graph) processing frameworks like Apache Flink or Apache Spark.
In our talk, we want to give an overview of our current implementation of Cypher on Apache Flink. Cypher is the Neo4j graph query language and enables the intuitive definition of graph patterns including structural and semantic predicates. As the Neo4j graph data model is not supported out-of-the box by Apache Flink, we leverage Gradoop, a Flink-based graph analytics framework based on Apache Flink that already provides an abstraction of schema-free property graphs.
We will give a brief overview about the technologies used to implement Cypher, explain our query engine and give a demonstration of the available language features. Finally, we will discuss open challenges and missing features hopefully motivating people to contribute.

It's a problem that concerns not only low-level library developers, but higher level software as well: for example, audio sequencer or video editor developer will still need solid understanding of underlying media file format structure to be able to debug any problems with it (like non-standard chunks inserted by some properitary software). We'd want to present Kaitai Struct, a new free/open source solution for file format dissecting, visualization and parsing. It is "write one - run everywhere" solution, where one needs to specify declarative file format spec once, and then compile it into ready-made parsing library in a large variety of supported target languages. And our visualization tools make Kaitai Struct work like "Wireshark for media files".

With many processors andlarge amounts of directly addressable storage, The Machine program hasoffered an equally large opportunity for developing new systemsoftware. Our team at HPE has spent the better part of two yearswriting new software and adapting existing software to expose thecapabilities of the hardware to application developers.
Taking off from my presentation at LCA 2016, this presentation willexplore the changes we've made throughout the Linux environment, fromsecurity infrastructure to new file systems.
As directly addressable storage is such a large part of the newhardware, this presentation will focus on a couple of important bitsof free software which expose that to applications, including ourLibrarian File System and Managed Data Structures libraries.
Managed Data Structures introduces a new application programmingparadigm where the application works directly on the stable storageform for data structures, eliminating serialization andde-serialization operations.
Finally, the presentation will describe how the hardware is managed,from sequencing power to a rack full of high-performance computinghardware, through constructing custom Linux operating systems for eachprocessor and managing all of them as parts of a single computingplatform.

In order to do that properly, you'll need to use tools that help you manage your infrastructure. This poses a problem: before you can manage your infrastructure, you now need to manage the infrastructure you will use to manage your infrastructure. The interesting bit is that if you use industry best practices, a lot of that management infra will look the same or similar across organisations. So why do we need to reinvent the weel over and over?

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

New Rust code can make use of that legacy of work via FFI, but to get the full advantages of Rust, legacy software needs to be re-written in Rust. Corrode is a tool to semi-automate these rewrites by producing Rust source that behaves exactly like the original C, enabling developers to focus on the interesting parts of improving code quality. I'll talk about what Corrode does and does not do; present case studies of Corrode-assisted translations; and discuss rationale for decisions such as writing Corrode in Haskell or documenting in "literate programming" style.

The talk will cover the topics listed below:
There are several ways of how to look at fault tolerance. In this sense PostgreSQL provides different means of achieving fault tolerance and dependability either out of the box solutions or using extensions depending on what are the user’s priorities about their system. General fault tolerance in PostgreSQL is improving over time and I expect this trend to continue.

The fast acquisition and very high (sub-meter) resolution are well suited for repeated measurements and assess terrain morphological changes. The processing sequence is
fly and acquire georeferenced images. If only a GPS receiver and camera are aboard the UAV, matching time tag with GPS date and time will allow for georeferencing the pictures (exiftool)
identify matching points between adjacent images: the GPS position is used to reduce the number of comparisons and limit the lengthy analysis to nearest neighbors
identify lens properties, bringing the largest cause of uncertainty in the model generation, from various pictures of the same ground feature exhibiting as much height variation as possible,
generate coarse point cloud to assess camera position and matching algorithm consistency
generate dense point cloud, orthophoto and DEM
include the resulting georeferenced pointcloud in QGis, converting the (arbitrary TIF) pixel value to quantitative height (meters).
We demonstrate sub-meter resolution DEM generation in vegetation-less environments (urban, glacier moraine) while coarse-acquisition (C/A) single-frequency GPS only allows for 5-m accuracy, hence requiring an additional ground control point matching step for repeated DEM comparison.
This presentation is a shortened sequel to the FOSS4G presentation given in 2016 (in French at the moment) focusing on UAV azimutal images.

In the worst case theyare reported by the customer, so they probably have already done some serious damage - frustrated the user, made themlose trust or even corrupted their data. Finding these bugs or recognizing them early gets especially hard, ifyour application makes heavy use of background processes, daemons or cronjobs. They might even throw exceptions thatare buried somewhere in the logs, and no one will ever be aware of them, until someone has a look into the log files.
I want to show a way out of this misery and provide different solutions in form of practical examples. These willinclude different levels of monitoring - from simple text logs on the servers up to a fully monitored applicationincluding hardware monitoring, extensive metrics, indexed and searchable logs of the whole environment, performanceanalysis and alerts if something odd happens. I'll show different examples and give ideas when such a fully monitoredsolution is a good idea, or when a "light monitoring" is applicable.

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

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

In an attempt to bring back some of the dataplane logic from the controller to the programmable switches, the OpenState abstraction layer has been designed, to enable efficient stateful packet processing through programmable actions occurring at the switch level.
The first part of this talk in an introduction to OpenState and includes a description of the layer as well as some example use cases. Then the implementation prototypes of OpenState realized during the project will be presented. One, in particular, will get more focus: because eBPF (extended version of Berkeley Packet Filter) can be stateful and has been conceived to reach high performances for inline packet filtering and processing, we found it to be an excellent target for OpenState.
As for the background: the work around OpenState (and its extended version, Open Packet Processor) has been achieved in the context of the BEBA research project (Horizon 2020), that tackles dataplane programmability for SDNs. Started in January 2015 and closing in March 2017, this project has entered its final stage, mostly centered on functional and performance tests for the validation of the developed prototypes.

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

It has a stackable architecture so that it is very easy to introduce a new feature. When storage (in any sort) comes into picture, security and privacy are two important features which are of concern to everyone. SELinux is one among the trending facilities which provides both. From the server-side view GlusterFS works well in SELinux environments, but this does not address SELinux support for the contents stored on Gluster volumes. This presentation will cover one step further; how an end user can use SELinux context over Gluster volumes. In the world of Storage As a Service this is a feature that everyone will love to have.

They complement traditional dynamic testing: Where testing allows individual runs through a piece of software to be checked for correctness, static analysis allows multiple and sometimes even all flows to be checked at once. Infer is an open-source static analyzer that is used internally at Facebook to analyze the main apps for Android and iOS, Facebook Messenger, and WhatsApp, among others. Infer reports bugs responsible for app crashes and performance issues, such as accessing null pointers, and leaking resources such as Context instances.
Each month, hundreds of potential bugs identified by Infer are fixed by our developers before they are committed to our codebases and deployed to people's phones.
This talk will present Infer and show how it can be integrated as part of the development workflow.

Prometheus comes with a powerful query language allowing for statistical evaluation of metrics. Many modern infrastructure components have Prometheus metrics built-in, like Docker's cAdvisor, Kubernetes, or Konsul. Prometheus' service discovery mechanisms make monitoring these components very easy.
The OMD Labs Edition is a collection of proven monitoring tools like Nagios or Icinga together with newcomers like InfluxDB and Grafana to provide a best-practice monitoring platform with advanced features like multi-tenancy. OMD Labs Edition bundles exclusively open-source tools and is itself developed open-source.
By adding Prometheus to its stack, OMD Labs Edition is also ready for cloud-native applications. As such it eases the integration of traditional monitoring with the needs of dynamic cloud monitoring.
This talk gives an introduction on how to integrate Kubernetes monitoring using Prometheus into the OMD Labs Edition.

Numerous techniques and metrics were developed. However, there is still a need in an approach that can both assert program domain and provide some reliable metrics. And such approach exists. It is called Mutation Testing. Here is a brief overview:
There is a function and a test for that function. Any semantic change in the function (so called 'mutant') should break the test ('kill mutant'). If that's not the case, then mutant is considered as survived.No mutants should survive ever. If they are, then either the test is bad or the function is not correct.
Research in this area exists since 70's. However, this approach is not widely adopted. The computational cost is one of the blockers. Another one, is the way such systems are implemented: most of them do mutations at the AST level, hence they are tightly coupled to the particular languages.
We want to present you Mull: our implementation of Mutation Testing system. We use JIT and runtime compilation to speedup the system and make it accessible for everyday usage. Besides that we go down to the IR level, making the system applicable for any LLVM-based language such as C, C++, Rust, Objective-C, and many others.
Heard about OpenDaylight and SDN? Ready to get your feet wet and start kicking the tires with an OpenDaylight installation? This session provides a brief intro to Software Defined Networking (SDN) in general, and more specifically to OpenDaylight, an open source platform for programmable SDN. After providing a high level overview of the architecture, the session goes on to show you how to deploy OpenDaylight and interact with it through the CLI and graphical tools. You will learn how to configure various options and enable/disable various features, and how to check the logs to verify things are working as planned and trouble shoot things when they are not. Lastly we show you how to interact with OpenDaylight through its northbound APIs for network aware applications and southbound plugins to physical and virtual network elements.

A first optimisation is a speedup of Helgrind (a race detection tool). A verysimple observation has led to an optimisation in the way helgrind capturesstack traces for its 'full recording' of where a piece of memory wasmodified. This optimisation gives a typical speed up of 25%. We will describethe issues encountered during the implementation and discuss the reasonswhy this optimisation is not (yet?) committed in the Valgrind sources.
The second optimisation is the implementationof the execution tree concept : this generalises the wayMassif (a heap profiler) records the memory usage of a program.We will show how a (maybe counter-intuitive) representation of a treeusing a hash table of flat stack traces has doubled the speed ofMassif for some workloads.
This talk is aimed at Valgrind developers and any application developerinterested in data structures and algorithm optimisations.

In 2012 the standardization of Opus changed that for audio through the combined effort of several individuals who were part of the free software community and large companies bringing together their research and patents and offering it for free use by everyone. By avoiding existing patents, interesting new techniques for efficient audio compression were invented.Now, in the effort to make a royalty free video codec in the same spirit as Opus, even more companies have joined into the "Alliance for Open Media" organization, with its first codec titled "AV1". Starting from the codebase of Google's VP9 codec, AV1 has currently over 45 experimental coding tools contributed by its member companies with the hopes that many will make it into the final version of the codec. This talk will serve as an update to the overall progress of the codec as well as to briefly explain the principles of operation of several coding tools expected to make it into the final version.

It is quite easy to expose some simple bindings and get a "hello world" application running in no-time.
However, after this first hello world, you'll quickly notice that you'll need other features such as timer, networking, file access, threading or even graphics and audio. At this point things get much more complicated, and maintaning the bindings can quickly become overwhelming.
Our team has been creating such bindings for SpiderMonkey since 2007 in several projects and this talk will present best practices, tips and caveats that we have learned over the years. We will also see how to make embedders life easier by using nidium library that bundles many basic bindings, in the hope that more developers can use the power of SpiderMonkey in a convienient way.

For example, one can get insights about buyers’ behavior by analyzing frequent co-occurrences of products in shopping baskets. In contrast, frequent subgraph mining (FSM), the graphy variant of frequent itemset mining, not only evaluates entity co-occurrence but also relationships among entities, i.e., structural patterns. However, existing implementations are all research prototypes which are tailored to textbook problems.
In our talk, we want to give an introduction to the FSM problem on distributed collections of graphs and our implementation in Gradoop, an open source system for scalable graph analytics based on Apache Flink. In contrast to other iterative graph algorithms like page rank, in FSM the search space is dropped but intermediate results of iterations are the desired result. Here, the major technical challenge is the respective usage of Flinks’ distributed iterations.
We will explain different implementation approaches, discuss implementation details which influence scalability and show benchmark results.

On Software Defined Radio (SDR) platforms, separating the channels can prove more difficult though due to high requirements for the digital filters. This talk will showcase an implementation of a polyphase filterbank on a graphics processor unit (GPU) that can help overcome the heavy computational load of those filters. In the software, all the partitioned filters can run in parallel. Each of these filters produces output samples for numerous input samples simultaneously, thus providing an additional parallel approach. Furthermore, several rational oversampling factors are supported by this implementation. Operations for oversampling can as well be implemented to run in parallel, due to the massive amount of usable hardware threads in a GPU. Hence, the effects of oversampling on the throughput can be reduced. On an Nvidia GTX970 GPU, this implementation achieved a throughput of 67.43 MSamples per second, 12 times higher than the (optimized) general purpose processor (GPP) version.

Bespoke database software seems to crop up daily in the name of performance or functionality. This talk will examine the ever growing field of monitoring systems and their respective databases, and look in depth as to how Postgres can be used in a number of these places. Systems of this nature are typically tasked with collecting and storing metrics from your infrastructure, drawing pretty graphs, and nagging you when things break.
Forms of data stored by these systems are nothing to be afraid of - they often include:- Time series metrics - the history of a measurement over time, e.g. temperatures- Logs - unstructured text emitted by applications, operating systems and hardware- Events - schema-less but well structured notifications
An assertion of this talk is that for a majority of use cases, Postgres is more than capable of storing all of this data. We will attempt to replace numerous well known pieces of software with just one Postgres database. Of course we are told to use the right tool for the job, but having to learn and operate a single tool is a huge operational advantage.
We’ll get quite technical in this talk, take a look the data models and access patterns required, and how this can be fitted into the general purpose environment of Postgres. Additionally, it is always constructive to look at what can be problematic, and not just focus on the positives, and why many turn to other bespoke solutions.

The new OpenSIPS version follows a Subscribe/Notify model, which allows the SIP routing to be driven by events. These events are triggered from both inside and outside OpenSIPS, and are internally dispatched by OpenSIPS to the right process/subscriber.
During this presentation, I will show how the asynchronous architecture revamp of the upcoming OpenSIPS 2.3 facilitates a series of state-of-the-art integrations (SIP transaction pausing while push notifications are taking effect, custom suspend-resume logic while waiting for an external event, etc.).
The discussion will also include OpenSIPS scripting, and how we tweaked it to incorporate all these changes in a simple, straightforward, and efficient manner.

This talk discusses how we were driven to create a multipurpose graph object specification for JavaScript and what were the design issues we soon had to tackle from implementation choices to API naming.
The result of this work is the graphology specification & reference implementation which we present to open it to feedbacks & contributions.
We will first review the state of the art of graph libraries for JavaScript and discuss the issues which brought us to create a new projet from scratch.
Then we will explain why we chose to design an open specification for a standard API rather than only providing a library.
Finally we will present the reference implementation & the attached library of algorithms and justify the technical choices made, before presenting our future roadmap and related projects (a new version of the graph rendering library, sigma.js, notably).

The compiler is the one tool that sees just about every piece of code, and is a position to both check for security and improve security. LLVM cannot magically write secure code, but it can help a professional programmer write really good secure code.
In this talk we will introduce our joint research program with Bristol University to add such features to LLVM. This project is still in its early stages, but we will present our initial work and discuss our future plans. A particular goal is community feedback on the priorities for this research program.

The ultimate aim is to achieve greater decentralization of federated services, such as social networking, file sharing, blog or email, on the net.
While many people are looking at containers as a way to run massive applications, automatically scaling to millions of users, Puffin allows running many independent personal lightweight applications on a single physical machine.
The first part of the project is a specialized application catalog for Docker, with easy to use interface à la app store, that can be easily run on a personal server. The second part is a common hosting platform which allows running limited number of applications for free.
During the presentation I will introduce the ideas behind the project and show a demo.

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

Our example use case integrates reconfigurable hardware accelerators into the Crypto API. We apply a new, declarative and device-tree-driven reconfiguration framework within the Linux kernel as proposed and implemented by Alan Tull.The implemented concept maps reconfigurable regions within the FPGA to device tree nodes. The insertion of a device tree overlay triggers the reconfiguration of the corresponding reconfigurable region. The reconfiguration process consists of the scheduling, descheduling and execution phase. Based on our usecase, benchmark results for the scheduling phases are shared.We present the bottlenecks revealed by our benchmark and show currently missing components of this approach. We conclude that the current implementation is already in a usable state for developing and deploying MPSoC-FPGA based heterogeneous systems.

But troubleshooting Kubernetes can be incredibly challenging due to the dynamic and isolated nature of the containers it orchestrates. Sysdig leverages the powerful concept of container-aware system events and correlates each one of them with super rich metadata Kubernetes.
In this session we’ll go deep into a real Kubernetes issue involving wget, search domain, glibc, SkyDNS and etcd, and we’ll see how to track them down using Sysdig.

This talk will introduce F9 microkernel aimed at low resources embedded systems powered by ARM Cortex-M microprocessors, allowing to perform real-time activities while keeping the drivers and the application isolated by a secure layer.
F9 microkernel proved itself extremely small and simple to use while still maintaining the security of the system regarding the temporal constraints with a trusted computing base (TCB) as small as 3kLoC, which is important for safety, security and reliability in mission-critical embedded systems. This talk will also present the prototype at its early stages built to experiment with the idea of third-generation microkernels heavily inspired by seL4 for resource-constrained devices with fairly strong memory protection.

It unpicks blocks of machinecode, hands them off to the tool for instrumentation, recompiles theresult, and links the instrumented version into the running image.By using a target independent intermediate representation, it insulatestools from the complexity of the underlying instruction sets.
Back in 2003, when the framework was designed, I never dreamt that itwould end up supporting X86, ARM, POWER, MIPS, S390 and TILEGX in both32- and 64-bit variants. From that perspective VEX has been amazinglysuccessful. But the framework is now showing its age. Recentinstruction set features (transactional memory,LoadLinked/StoreConditional, wide vectors) have proven difficult toimplement. It supports precise memory exceptions only poorly. Andperhaps worst, its simplistic compilation pipeline causes it togenerate code that is uncompetitive compared to other frameworks,particularly DynamoRIO and PIN.
In this talk I'll outline VEX's structure, then talk about theseproblems and what can be done about them. And I'd be particularlyinterested to hear opinions on how much effort, and for which problemareas, should be invested in upgrading it.
For the audience, some background in compiler internals and assemblycode programming would be helpful, but is not essential.

However, booting the system required storing the loader and kernel unencrypted so that the requisite GEOM module could be loaded to handle decryption. This became a significantly larger stumbling block with the introduction of ZFS, as having multiple separate partitions detracts from the advantages of ZFS, and also causes headaches when upgrading the operating system. With the growing popularity of ZFS Boot Environments, a solution was needed that allowed the kernel and loader to remain part of the primary file system, even if it was encrypted. This paper provides an overview of the design of the GELI enabled BIOS boot code and loader, as well as the numerous challenges encountered during their development.

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

Now learn about the follow-on project which expands the reach of NiFi to the edge, Apache MiNiFi. MiNiFi is a lightweight application which can be deployed on hardware orders of magnitude smaller and less powerful than the existing standard data collection platforms. With both a JVM compatible and native agent, MiNiFi allows data collection in brand new environments — sensors with tiny footprints, distributed systems with intermittent or restricted bandwidth, and even disposable or ephemeral hardware. Not only can this data be prioritized and have some initial analysis performed at the edge, it can be encrypted and secured immediately. Local governance and regulatory policies can be applied across geopolitical boundaries to conform with legal requirements. And all of this configuration can be done from central command & control using an existing NiFi with the trusted and stable UI data flow managers already love.

Unfortunately, vendors provide the drivers for the accelerators only as binary blobs. We demonstrate how we built a video playback system that uses hardware acceleration on i.MX6 by using solely open source software including Gstreamer, Qt QML, the etnaviv GPU driver, and the coda video decoder driver.

While these standard data formats have dominated web-based applications, they also have further applicability in a wide variety of non-web contexts. This talk will introduce you to José, a plug-able, open source C implementation of these RFCs which provides both an API for direct integration and a usable command-line interface. We will discuss the techniques that we used to keep our API usable across all the possible input parameters and show example of how you can implement José in your own infrastructure. We will also discuss some of our plans for the future, including how you can help contribute.

End users of consumer devices aim to have an instant gratification which is based on data/metrics produced by the object.At the end, IoT makers have to execute an epic split:Build the actual device (mechanical and electronics),Be over the top in firmware development in order to be securedDesign services based on the object data.Surrounding all that is a hard job for a product team. In such a context Open Source Software constitutes basic building blocks of IoT devices.Data produced by smart devices are often time series, storing them is not the challenge, many good open source solutions exists (OpenTSDB, Influx..) but developing algorithms based on your data is difficult. It can become a nightmare if you have to think about scalability.Warp10 is a 3 years old open source platform designed for collect, store and manipulate sensor data with WarpScript, a language dedicated to time series analysis. WarpScript works natively on times series stored into Warp 10 (based on either levelDB or HBase) but can be connected to any data source.When you manipulate sensor data, you must deal with privacy. Security and privacy have also been addressed by Warp 10 since its very inception, this includes fine grain access control mechanisms, encryption capabilities and throttling management.Warp10 plateform can be integrated into an open ecosystem likes Storm, Flink, or also Apache Pig with one cornerstone, the capatibility of manipulate time series with WarpScript.

Window functions act as regular functions but have access to more than one row during computation. This makes them highly useful for optimising queries involving self-joins, as well as queries that need to extract data from multiple related rows from the same table. The performance speedups obtained are sometimes 100 fold. This talk will explain how that is possible, as well as use cases for window functions.
On top of that, window functions pair well with another feature that MariaDB 10.2 has introduced - Common Table Expressions. This feature was contributed by a community member and helps make queries more maintainable and sometimes faster. This feature will be covered, mostly through the use of window functions, but also introduce new use cases.

Up to recording everything they see on the screen, the commands they execute, and files they access.
In this presentation Nikolai Kondrashov will review available solutions for user session recording, open-source and otherwise, their benefits and shortcomings, and will present a new effort to create an integrated Open-Source solution.
While there are many capable solutions for session recording, which can centrally collect, search and playback sessions, there is no such open-source code. The best we have is jump servers with script(1), or sudo I/O logging, all manually set up. This presentation will show an approach that would meet the needs of the modern enterprise.
The presentation will include a demo of a user session and accompanying data being recorded, stored centrally, inspected and played back.
The intended audience is developers of security, identity and policy management systems, as well as system administrators and security officers responsible for maintaining critical systems and preventing insider attacks.

What if users could support your project with tiny amounts of money each time they use it? What if we could use anything of value as "currency" and have it automatically exchanged when we want to make a payment?
Interledger is the inter-networking protocol for money. It enables secure transfers across different currencies and payment networks. By connecting all different types of payment networks or ledgers together, Interledger can help create an "Internet of Value".
This talk will include a demo of an Interledger payment, a technical overview of how it works, and examples of how Interledger can be built into other projects.

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

There are a number of tasks where MySQL does not show great performance: for example MySQL is not massively parallel system and a single query will only utilize 1 CPU core . Spark, on the the other hand is designed to be massively parallel; in addition Spark is a clustering framework, so you can easily add more compute nodes so that Spark can utilize more resources and scale.
Apache Drill is similar project aimed to make data discovery easier. For example it allow you to join data sources in MySQL, MongoDB, flat files, other RDBMS, etc.
In this talk I will demonstrate how to use Apache Spark together with MySQL for data analysis. I will sho how Apache Spark aggregates data (wikipedia pageview statistics) and stores the resultset in MySQL. I will also show how to use Apache Spark with multiple sources and join virtual tables from MySQL, flat files and even MongoDB.

Inet had to fit in with MINIX. In particular, it had to live with minimal changes to the MINIX code base. At the same time, there were quite a few areas where I felt sockets and the BSD TCP/IP implementation were wrong.
In hindsight, there is a lot that I did not know and got wrong. I this talk, I will look at how inet follows the structure of MINIX, what works, and what went wrong.

Having a unified data processing engine empowers Big Data application developers as it makes connections between seemingly unrelated use cases natural. This talk discusses the implementation of the so-called BigPetStore project (which is a part of Apache Bigtop) in Apache Spark and Apache Flink. The aim BigPetStore is to provide a common suite to test and benchmark Big Data installations.

It serves as the basis of the NixOS Linux distribution (that can be automatically installed from a single declarative specification), as well as a number of additional deployment solutions, such as NixOps, that deploys virtual machines in the cloud and Hydra: the Nix-based continuous integration server. Although Nix offers all kinds of deployment benefits, integration with language-specific package managers that also do dependency management, such as the NPM package manager, is problematic as they conflict with Nix's reliability properties. In this presentation, I will show node2nix, a tool that automatically generates Nix expressions (build recipes) froman NPM package's package.json configuration file, allowing users to deploy NPM packages with the Nix package manger alongside other types of packages (e.g. Autotools, Perl, Python, ...) that constitute a large complex system.
Internet Transport is changing, some changes have been incremental updates tomechanisms (e.g., RACK, BBR), others demand new protocol options (e.g., MPTCP)or entirely new protocols (e.g., QUIC, SCTP). However significant changes arestill difficult to deploy - requiring modifications to application code andsupport by the stack. Even when updates happen, the network needs to supportthe new method to allow applications to use it. Long deployment times havemotivated the need to change how protocols are handled in the stack. We reviewthe state of the art in Internet Transport, and the status of deployment in thBSD's and then propose a new direction for the transport interface, developedin the EU NEAT Project, that can ease deployment of new transports across allplatforms. We conclude by showing the advantages and its prospects forstandards adoption.

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

However, for many enterprises, much of their important data resides in relational databases and SQL is the most common workload. So is it reasonable to suggest that relational data processing engines can be used to solve graph problems in a productive and performant manner?
The answer to this question is: “Yes!”
In this talk, we will address the use of massively parallel processing (MPP) databases for graph analytics workloads. We will share some recent findings from the Apache MADlib (incubating) project, including design of graph data structures, implementation of common graph algorithms, and performance results.

What are the differences between them and which one is more suitable for each GIS application? This talk addresses this kind of questions and how geography is implemented in Boost.Geometry. The library that is currently being used to provide GIS support to MySQL.
Following up the introductory talk on Boost.Geometry we discuss the algorithmic, the implementation as well as the user perspective of the development of geography in Boost.Geometry. We define basic geometric objects such as geodesics, and the modeling of the Earth as a sphere or ellipsoid. We try to understand the effect of different Earth models to the accuracy and speed of fundamental geometric algorithms (such as length, area, intersection etc.) by showing particular examples. Finally, we are having a look towards the future of geography in Boost.Geometry.
Comment: This is an entry-level talk on subjects of GIS, geometric algorithms and Boost.Geometry. Attending the introductory talk on Boost.Geometry will help the audience to have a more detailed understanding of the Boost.Geometry development but it is not considered as a prerequisite.

DESCRIPTION:The workloads and scenarios for virtual machines grow more complex every year. So do the interactions, availability, and performance requirements. All that requires the administrators to carefully plan where to start the VMs that depend on each other and/or specific hosts.
This talk will present the concepts that allow the administrator to express the rules for affinity between virtual machines and between virtual machines and hosts to form complex relationships that will cover for example:
oVirt is an open source project for managing virtual data centers that will now help the administrator with exactly the above tasks. We have introduced the virtual machine affinity feature in the past and a huge improvement in that area is coming right now.
And the best part is that all this works in a fully dynamic environment with automatic conflict resolution and no manual management of host pinning rules, saving the administrator his precious time.

Often, physical access to these devices is limited and there is no administrator who can fix issues manually. Thus, performing updates is an operation with a critical design goal: Never brick the device!
This talk gives an overview of the surprisingly complex requirements and common pitfalls for a generic update mechanism by comparing several existing approaches. Also, our reasons for implementing (yet another) tool and the reasoning behind the design choices are explained.

Dgsh allows the specification of pipelines of non-uniform non-linear operations. For example tee can feed three processes whose output can then be collected by paste. The pipelines form a directed acyclic process graph, which is typically executed by multiple processor cores, thus increasing the task's processing throughput. We will see how to use dgsh in practice through a number of general data processing and domain-specific examples, and how to adapt tools for use with dgsh.

In this talk, we will show how we attack the Data and Infrastructure challenges for Deep Learning. Specifically, we will show how we integrated Tensorflow with the world's most scalable and human-friendly distribution of Hadoop, Hops (www.hops.io). Hops is a new European distribution of Hadoop with a distributed metadata architecture and 16X the performance of HDFS. Hops also includes a human-friendly UI, called Hopsworks, with support for the Apache Zeppelin Notebook. We will show how users can run tensorflow programs in Apache Zeppelin on huge datasets in Hadoop. Moreover, we will show how Hopsworks makes discovering and downloading huge datasets a piece of cake with peer-to-peer sharing of datasets between Hopsworks clusters. Within minutes, you can install Hopsworks, discover curated important datasets and download them to train Deep Neural networks using Tensorflow. Hops is the first Hadoop distribution to support Tensorflow.Hops and Hopsworks are both Apache v2 licensed projects and have been developed primarily at KTH Royal Institute of Technology and SICS Swedish ICT in Stockholm.

This fact is well addressed, but it would be great to utilize your cluster in that way, that you locate your data in the same cluster like the rest of your application landscape and share your physical resources all over your running applications, no matter if you are serving user requests, crunching data or calculating big graphs. For this reason we brought the awesome graph database Neo4j to run natively on top of Apache Mesos and DC/OS.In this session we will see how easy it is to install, run, operate and scale out Neo4j Causal Clusters on top of Apache Mesos and DC/OS and which possibilities you have spanning big graphs across your cluster.

For the most part, this is caused by existing applications that depend on the file abstraction and to some extent on a global view on system resources. In contrast, component-based OSes with strong security ambitions strive to apply the principle of least authority and shun one global view on the system. This was the starting for the VFS developments for Genode. The talk will present our design considerations and the current state of the VFS in Genode as a component and capability-based microkernel operating system.

The syslog-ng application is an enhanced logging daemon, with a focus on central log collection. It collects logs from many different sources, processes and filters them and finally it stores them or routes them for further analysis.From this session you will learn (using examples from syslog-ng) why and how to parse important information from incoming messages, and how to route logs, feeding downstream systems using arbitrary formats. We will also discuss how the client – relay – server architecture can solve scalability problems. Also, I will present some of the recently introduced “Big Data” destinations of syslog-ng, which can help to scale your infrastructure even further.

Update on a package basis that is used by PC Linux distributions can be a security threat by itself on embedded devices. On the other hand, full fylesystem upgrade that is common in embedded field can be too wasteful for systems constrained in network bandwith and disk space. OSTree is a tool that allows for upgrades that are both incremental and atomic and as such perfectly fits the needs of embedded world.

MySQL has had a quite mature and feature richreplication solution for over a decade now. Moreover, there areinteresting new features that allow users to create quite advancedsetups. Nowadays, there is group replication, multi-source replication,and of course plain asynchronous replication that allow users tocreate interesting new setups.
In this session we will present recommended ways to mix and matchgroup replication with regular asynchronous replication.

The Radio Equipment Directive requires all devices that are able to send and receive radio signals to be locked down. This goes much further than the FCC lockdown in the US since it doesn't only affect routers but also mobile phones, GPS receivers, and amateur radio operators.
From June 2017 hardware manufacturers will be forced to install technical measurements to protect the devices from being flashed with "non-compliant" software: firmware that hasn't been checked by the manufacturer to comply with applicable radio regulations (e.g. signal strenght, frequences). Many European states already have implemented the directive in national law without many ways how to circumvent the major lockdown.
However, we have identified possible ways how to excluded certain classes of devices from this directive. The speaker will evaluate the current situation, present additional findings and opinions of political and economic actors, and exchange ideas and knowledge with the audience.

The second problem is solved by expanding the signal model that is used in bearing estimation algorithms (such as MUSIC) to account for LO offset.The proposed system is implemented on a USRP-N210 SDR with an external high-end IMU and tested in an anechoic chamber. The SDR implementation is a mixture of FPGA and software development, while some parts of the data are processed off-line. The results show that our method is indeed feasible, with bearing estimation errors of only a few degrees. We then present the first efforts of an implementation on a USRP-E310 SDR which has an integrated, lower-quality IMU.

NVDIMM is not simply a fasterblock device. Programs can avoid block I/O entirely and use byte-addressableNVDIMM to benefit from the performance characteristics of RAM. This requiresnew storage APIs that applications must use instead of traditional block I/O.
These new programs run successfully inside KVM virtual machines thanks to thevNVDIMM support already available in QEMU. Virtualization offers additionaloptions for managing and using NVDIMM beyond what is available on bare metal.
This talk covers the NVDIMM programming model and how KVM virtual machines canuse NVDIMM for faster I/O, reduced memory footprint, and faster boot times.

We demonstrate a fundamental concept in network analysis: re-construction and visualization of temporal networks. Furthermore, we apply the method to describe operational conditions of a Hadoop cluster. Our experiments provide first results and allow a classification of the cluster state related to current workloads. The temporal networks show significant differences for different operation modes. In reallity we would expect mixed workloads. If such workload parameters are known, we are able to handle a-typical events accordingly - which means, we are able to create alerts based on context information, rather than only the package content.We show an end-to-end example: (1) Data collection is done via python, using the sniffer script; (2) using Apache Hive and Apache Spark we analyze the network traffic data and create the temporary network. Finally, we are able to visualize the results using Gephi in step (3). In a next step, we plan to contribute to the Apache Spot project.

In order to understand the struggles and/or challenges of minorities in tech and foster a safe environment for their inclusion, we need to be better listeners. One way we are able to get access to the voice of our users is through user research. However in order to increase effective communication we need to learn the art of listening. Several of us were taught to speak, read and write, but we simply assume we know how to listen. There is a saying that less than 2% of people have had any formal education on how to listen, while that is a skill that many of us use in our daily lives. Through this talk we will understand the difference between hearing and listening; we will also explore active listening and how it can better help us in our user research.
Women in Open Source Technologies - Kristi Progri
The Gender Gap is one of the most talked topic since forever, and still a Gap. Where are the women in Open Source? Why is the gap so big? Women participation in open technology and culture is very important so we should all pay more attention. This talk will be focused on the large steps we can take to reduce this gap. Also we will share out experience at our hackerspace in Tirana, Albania since we have lots of women there.
Let's face it: Gender Diversity in Tech is in a quite bad shape. The sad thing about it is that it's even more noticeable in many Open Source communities in particular. But why is gender diversity important?
It’s not just diversity for the sake of diversity. If men and women are equally intelligent, statistically speaking, then out of the smartest ten people in the world, five should be male and five should be female. Thus, if your team is anything less than an equal balance of men and women, then your team is probably not the best it can be.
Unfortunately, if we take a look at a random sample from GitHub active contributors from 2015, just 5.4% of GitHub users with over 10 contributions are female.
Let's talk about the ways we can fix this and what efforts Mozilla does to improve this and how you can help Mozilla help the community, concretely with Womoz (Women at Mozilla) and the Diversity & Inclusion Team at Mozilla.

Wouldn't it be great if those debug statements could just stay in your code forever? Like a little gift that keeps on giving, not just for you, but for everyone else on your team too.
That's what an application log is for! Logs aren't just for when things go wrong. They're for helping you to keep track of what's going on within your application.
We take a look at how you can add helpful messages throughout your codebase and leave them there, even in production! We'll cover common logging strategies, log aggregation and how to efficiently work with your logs to get the data back out again.

Exactly Once Large-Scale Stream Processing in Action. DESCRIPTION:Large-scale data stream processing has come a long way to where it is today. It combines all the essential requirements of modern data analytics: subsecond latency, high throughput and impressively, strong consistency. Apache Flink is a system that serves as a proof-of-concept of these characteristics and it is mainly well-known for its lightweight fault tolerance. Data engineers and analysts can now let the system handle Terabytes of computational state without worrying about failures that can potentially occur.
In this talk, I am going to explain all the fundamental challenges behind exactly-once processing guarantees in large-scale streaming in a simple and intuitive way. I will further guide you through the tricks and pitfalls that we faced in our effort to make state management easy to use, transparent and yet extraordinarily powerful. Finally, I will demonstrate how you can declare state and the in-flight protocol that is running underneath your processing pipeline to guarantee that your computation will always run consistently and uninterrupted, until infinity.

We created many features for easier migration, such as fast data loading, online data correctness check tool. I will share with you about lessons learned from our initial migrations and impacts what we have seen.

And it’s about time: our copyright laws are out of step with today’s technology. But the proposal to reform copyright lacks ambition, and is inadequate to address the today’s challenges. It even contains some very dangerous provisions - such as a snippet tax, and upload filters for online platforms - that would put the open internet, innovation, and creativity, at great risk. This session will unpack some of the key issues at stake in the reform and how you can get involved. Together we can achieve an EU copyright reform that fosters innovation and creativity.

The platform specific languages are often harder to integrate with and require longer adoption time.
To fill this gap many NoSql (Not-only-Sql) vendors are building SQL layers for their platforms. It is worth exploring the driving forces behind this trend, how it fits in your BigData stacks and how we can adopt it in our favorite tools.However building SQL engine from scratch is a daunting job and frameworks like Apache Calcite can help you with the heavy lifting. Calcite allow you to integrate SQL parser, cost-based optimizer, and JDBC with your big data system.
Calcite has been used to empower many Big-Data platforms such as Hive, Spark, Drill Phoenix to name some.
I will walk you through the process of building a SQL access layer for Apache Geode (In-Memory Data Grid). I will share my experience, pitfalls and technical consideration like balancing between the SQL/RDBMS semantics and the design choices and limitations of the data system.
Hopefully this will enable you to add SQL capabilities to your prefered NoSQL data system.

How can we make use of these positives of distributions along with modern tools and technologies to produce a secure, stable, scaleable OS for IoT products?

One of the key features of Xen is that it is OS agnostic, meaning that any OS (with proper support) can be used as a host. Xen has a long history going back to the 90s when it was designed and the early 2000s when it was released. As a consequence of this, many of the assumptions and virtualization techniques backed into it are now superseeded by new hardware features, that make virtualization more transparent from an OS point of view.
This talk provides an overview on the different kind of guests supported by Xen and how these new hardware features are used in order to improve and evolve them. It also describes the design and implementation of a new guest type, called PVHv2, and how it can be used as a control domain (Dom0).
