Before scientists can use HPC systems for their research, they need to get the tools and applications installed that they require.
Until recently, this was a (perhaps surprisingly for some) painful process,especially for scientists that lack sufficient experience with compiling software and dealing with dependencies.
Recently, several projects have emerged that aim to facilitate this process, each of which with a particular focus:performance, flexibility, reproducibility, ease of use, support for multiple platforms, etc.
In this talk, I would like to present an objective comparison of the different tools that are most prevalent currently, including:
Although I intend to focus on the use case of installing (scientific) software on multi-user HPC systems, I will also highlight particularly interesting features that fall outside that scope.

DESCRIPTION:Today, many new programming languages have been created in order to simplify at the extreme the art of programming (Golang), to boost the performance of their human readable application (Nim), to secure the way to make and run programs with zero-cost abstraction (Rust), or just to propose a new exiting way to write programs (Scala, Swift), etc.Each of those new programming languages has its own features, goals, attendance, and community.
Today, it may become hazardous to develop with a new programming language, especially for a company or for a full-time personal project, due to the lack of stability, libraries, IDE features for this programming language, a too small or strict community, or many other obvious reasons.
The goal of this presentation is to introduce the concepts of Rust, its pros and cons, and how Rust differs from the others programming languages.The target audience is mainly for developers who are reluctant to launch themselves into Rust, or project managers and CTOs who are looking for stable and exciting new technologies.
This talk is intended to emphasize Rust rationale, and will explain clearly and precisely why Rust wants to be the programming language of the next ten years.

Users want to connect more storage devices and use them efficiently. Cinder has been solving this use case in Openstack for a long time and can be integrated with any kubernetes cluster regardless of its cloud provider. By deploying a standalone cinder service and a new external provisioner to a cluster, pods can access almost any volume that cinder is able to provision. Complex operations such as cloning, snapshots, and migration become services of the cluster. This presentation will describe and demonstrate a cinder external provisioner, enumerate its advantages, discuss challenges especially around deployment, and propose collaboration opportunities between Openstack and kubernetes.

The media present the GDPR on a daily basis in volumes no one has expected. The whole commercial sector is hyped with articles about the GDPR, recommendations, warnings and in the end MYTHS! The GDPR is not only multinational corporations’ concern any more. Individuals and small entrepreneurs are looking for the answers too. This makes space for speculations and many partial solutions are offered in a form of a GDPR project draft templates or migration of processing into the new safe environment without appropriate paperwork. Even software solutions usually offer only partial safety measures and you will need a bunch of them to fulfill the GDPR project.A complete solution exists only as cooperation of legal person analyzing interpretation of EU legislative and IT technician able to incorporate those requirements into daily operations. The complete solution still does not mean 100% compliance because there are so many threats you can never be utterly safe from.This presentation will tell what you must not omit to be compliant, how to give effects to the rights of data subjects and how to craft your GDPR solution. We will discuss lawful basis for data processing, consent requirements and tools able to manage them effectively. In the end, we may think about the design of identity management tool that combines the advantages of identity management into one solution dealing with various GDPR issues.Included GDPR areas in light of Identity management: Lawful basis and consent management, risk assessment, data breach tool, DPO’s control tool and data subject’s rights control tool.

Likeother HPC package managers, Spack was designed to build packages fromsource. However, we've recently added binary packaging capabilities,which pose unique challenges for HPC environments. Most binarydistributions assume a lowest-common-denominator architecture,e.g. x86_64, and do not take advantage of vector instructions orarchitecture-specific features. Spack supports relocatable binaries forspecific OS releases, target architectures, MPI implementations, andother very fine-grained build options.
This talk will introduce binary packaging in Spack and some of the openinfrastructure we have planned for distributing packages. We'll talkabout challenges to providing binaries for a combinatorially largepackage ecosystem, and what we're doing in Spack to address theseproblems.

With a wave of their hand, bits can flow in any way, form, and manner. We’d like to leverage this newfound magic to support a multitude of new services.
Enter Dragonflow. Dragonflow is a fully distributed SDN controller, responsible for first-to-market features such as distributed SNAT and distributed DHCP. It is completely open-source and is an official Openstack project. It supports many networking services such as L2, routing, DHCP, security groups, and trunk ports. Additionally, it supports container networking through strong collaboration with the Kuryr project. One of Dragonflow’s strongest points is that it’s extensible. Plugging in new services and getting them to work together is incredibly easy.
In this talk we will discuss Dragonflow as an open platform for network applications, and the ecosystem of these services.

Map Algebra is a long established conceptual framework for geographical data analysis. It is a versatile and highly generic framework, classifying local, focal, and zonal operations. However existing libraries and tools that implement Map Algebra operations are not as generic and instead of a limited set of specific functions. The Pronto Raster library aims to overcome this and provides an efficient computational framework that allows efficient implementation of local, focal and zonal operations using user-specified functions.
The library uses GDAL to access and write raster data. A central concept of the library is the Raster, which is essentially a Range that iterates over the cells in a raster of values. The core focal and zonal operations produce Expression Templates that model the Raster concept. Therefore the outcome of zonal or focal operations on one or more Rasters is another Raster that does not hold data itself but refers to the data in the input rasters and combines the data lazily once the outcome Raster is iterated over. It thus becomes possible to combine and nest operations on rasters without creating temporary files. An additional benefit is that it is trivial to apply functions to only compute a subsection of the output Raster, which in turn makes the library very amenable to future parallelization.

Such a tool can bring closer together self-hosted software and community networks, making both more accessible to a wider audience. Openki, http://openki.net, is a FLOSS platform for self-organized education that facilitates the creation of collaborative learning groups in the city.

UWE Sense is a new hardware and software platform for IoT, build with ARM micro controllers, Bluetooth LE and LoRaWAN, which runs a software stack written completely in Rust. While UWE Sense is a close to the metal implementation, UWE Audio, a new hardware platform for studying high performance audio using ARM micro controllers, uses Rust to implement a monadic reactive graph, supporting both an offline compiler and and Embedded DSL. UWE Audio uses safe Rust, for example, describing domain clock as generic associated types, providing both compile time guarantees that multiple streams will not be incorrectly sequenced at different sample rates, and the ability to dynamically compile for different parts of the system.
In this talk I will provide a high-level overview of the Rustyarm project, including how using Rust has made this project interesting, but also enabled providing guarantees with respect to the audio scheduler, for example. However, Rust has some short comings in the embedded domain and we provide details on some of these and what we and the wider community are doing to address them. As an example of Rust’s application in the embedded domain we present early work on UWE Audio and hardware and software platform for building digital music instruments, which as already noted is programmed with solely in Rust.

An alternate approach is to use Brzozowski derivatives to directly generate deterministic finite automata. This talk describes an implementation of Brzozowski derivatives in Python, based on a paper by Owens, Reppy and Turon. This implementation is used for generating efficient Unicode lexers.

We were asked to make it possible tolet the smartphone app connect to the IP gateway from anywhere in the world.This vendor's IP gateway hard- and software was based on the Mbed platform, sothey needed a solution that could fit within Mbed.
First of all, there are a lot of ways to make a device in a local networkaccessible from anywhere in the world: SSH tunneling, port forwarding withdynamic DNS,... Since our client wanted an open-source, secure, low-cost andeasy to set up solution that he could host himself, we opted to go forPagekite. However, since Mbed does not support OpenSSL, Linux sockets orlibev, the existing libpagekite C library was not an option to start from. Sowe started to implement a Mbed flavour of the library ourselves, and decidedto make it open-source

Doing so allows documentarians to collaborate much easier with developers. While most teams have chosen for static site generators to implement this methodology, we identified a number of use cases where it would make much more sense to use a CMS based system. In this talk I explain why, and introduce a new open source project, based on Drupal, that can import Markdown and Open API specifications.

This means running recent software on enterprise Linux distributions that ship older software.Traditionally this is accomplished using environment modules, that change environment variables such as $PATH to point to the software that is needed.At Compute Canada we have taken this further by distributing a complete user-level software stack, including all needed libraries including the GNU C library, but excluding any privileged components.I will describe our setup, which combines Nix for the bottom layer of base components, EasyBuild for the top layer of more scientifically inclined components, Lmod to implement environment modules, and the CernVM File System (CVMFS) to distribute it to Canadian supercomputers.Expected prior knowledge: knowing how to use the command line and environment variables.

See http://staff.bath.ac.uk/masjhd/MattColes.html for more background on the project.
Systems with large amounts of multi-level cache available require the ability to profile cache performance at each layer, as there remains a significant performance disparity between L2 and L3 caches. An example of such a system and the focus of this work is the new Cavium ThunderX2 supercomputer at the GW4 Isambard project. This paper intends to detail the methodology used to extend the capabilities of the Valgrind tool: Cachegrind. This extension will enable it to model both the L2 and L3 caches separately, as opposed to as a single last level cache. This support will be added for both the ARMv8 architecture, in order to model performance on the Isambard supercomputer, and in addition x86_64, for comparative purposes. As a result of this extension, the Isambard project will be able to optimise frequently used programs, in order to reduce CPU time used and therefore improve throughput on the system.

During my master project i worked on combining LLVM with a WCET tool.
Worst-Case-Execution-Time (WCET) is the longest time a program can execute, typically measured in cycles.This information is typically of interest for code that has timing requirements such embedded systems in cars.
The project involved combining an open-source tool called SWEET with LLVM.This involves using datastructures in LLVM to output the interface-language to the tool SWEET.As a proof-of-concept, the ARM Cortex-m0 has been chosen and an attempt has been made to automatically generate a WCET analysis during compilation.
This talk will explain my findings in the project and explain the concept of WCET in general.

This talk presents the implementation of an opportunistic spectrum scanner on a software-defined radio platform, whose aim is to continuously scan the RF spectrum and to detect whether any signals are present. The implementation is done on a USRP-N210 software-defined radio, a popular and cheap model. One major bottleneck of USRP-based implementations is the limited CPU computation power, which does not allow to process RF signals at high sample rates continuously. In the proposed implementation, most computation is done on the USRP FPGA, such that the host CPU is relieved and is only used to store data and coordinate the scanning. We present the details of the FPGA and the software architecture, as well as some experimental results that show the efficiency of the proposed spectrum scanner.

Currently typical use of DNS by applications is limited to forwarding requests to the system's stub resolver, which in turn simply forwards it to the recursive resolver in the network which does all the heavy lifting; iterate over the authoritatives, secure the lookups with DNSSEC etc. This first-mile in the DNS eco-system (from application, via stub to the recursive resolver) is completely insecure and exposed. This makes the use of DANE (a secure alternative to the flawed CA based PKIX) impossible and also leaves end-users unprotected to DNS based connection hijacking and very exposed to eavesdropping attacks!
To deliver DANE and Privacy to the end-user, we need to address these issues as close to the end-user as possible. The getdns library is a resolver library for applications, providing a versatile stub resolver that takes care of all the difficulties and complexities that arise when these higher security and privacy demands need to be practiced for actual users instead of just networks.

DESCRIPTION:The Digital Transformation Team was born to build the "operating system" of the Italy, a series of fundamental components on top of which they can build simpler and more efficient services for the citizens, the Public Administration and businesses, through innovative digital products. Among the critical infrastructures, there's the way software is developed. Italy is betting hard on open practices, by not only opening the source code of the country, but also turning citizens and hackers into first-class participants of the digital transformation, giving them the power to develop and maintain software which impacts their daily life.
To sustain this switch, the Team is building hackerspaces throughout the country, to increase awareness of open practices, and is turning all developers paid with public money into open source contributors. After this talk, you will know how to "hack your government", how to participate in this change (even if you are not Italian!) and how we are working to spread this idea throughout all of Europe.

DESCRIPTION:Installing an operating system on single board computers (SBCs or "Fruit-Pis") is very board specific and requires a lot of hand holding. If at all, standard distributions support only a small number of them explicitly, which leads to a lot of board specific images and distributions. This talk will show how this situation can be improved, to the point where off-the-shelf Linux (or BSD) distributions can be installed on those boards, without those distros knowing about each and every one of them. Key ingredients are standardized firmware interfaces like UEFI, stable device trees and on-board memory like SPI flash.This should make using ARM based SBCs as easy as using (x86) PCs today: like "real computers".On top of this ways to simplify and speed up mainline Linux kernel support are explored. Enabling kernel support for new SoCs usually takes a while, especially if the effort is driven by the community. This delays distribution support, up to a point where a certain SoC or board might become slightly dated when it's finally supported. Using more device tree features and less hardcoded kernel data would reduce the code required to support new SoCs, ideally reaching a point where new SoCs could be at least booted with existing (distribution!) kernels, just by providing the proper device tree blob.This talk describes the idea and gives an example by looking at what can be done on Allwinner SoCs.

At UCLouvain, one of our clusters, and the services on which it depends, is built on a full FOSS stack. From the operating system, to the deployment tools, monitoring, scheduling, and user software installation, everything is built from open source software that inter-operate gracefully. For instance, for deployment/provisioning, we use a combination of Ansible and Salt which we find work perfectly together even if they are often considered to be mutually exclusive.This talk will share our experience with making FOSS software co-operate smoothly and will offer our point of view on choosing the right tool for the right job. It will also present some of the contributions we have made to the open source community.

DESCRIPTION:Starting with openSUSE Leap 42.2, a lot of cooperation has been done to bridge gaps between openSUSE and SUSE Linux Enterprise distributions. Things have been improving nicely with openSUSE Leap 42.3.We'll go into details on what this cooperation means for both openSUSE contributors and for SUSE and how we ensure it takes place.
We'll share a few statictics, discuss on the new SLE15 development and how is done in harmony with openSUSE Tumbleweed (rolling release).

This session provides a brief intro to SDN in general, and more specifically to OpenDaylight, an open source platform for programmable SDN. Next we dive into network programmability, including why we need it and the role of NETCONF, YANG, and RESTCONF. Then we put the theory into practice as we install OpenDaylight as use it a platform for programming a sample network.

With an order of magnitude of hundreds of millions of euro in research, development and engineering effort it can actually be a major step toward reaching the post-Snowden internet we want. NLnet Foundation and Gartner Europe that wrote the strategic vision for the Next Generation Internet initiative will present the work they did in a unique collaboration which sought the expertise of key organisations and communities in the field - like RIPE (the European regional internet registry), GÉANT (research networks), the European assocation of country domain name organisations, ISP associations, the internet exchanges, the open source community (FSFE), the digital civil rights community (EDRi) and Internet Society. So not just the separate communities that operate different 'layers' (or rather slices) of the technology but also what we consider 'ethical guardians' of the internet.

It parses configuration files intheir native formats and transforms them into a tree. Configuration changesare made by manipulating this tree and saving it back into native configfiles.
The tool, and this description, recently turned 10 years old, a milestonethat I will celebrate with a stroll down memory lane, looking at Augeas'original goals and subsequent achievements over the past decade. Over thattime, it has become an important building block for configurationmanagement tools like Puppet and Salt, and is used by tools such as EFF'sLet's Encrypt, OSQuery, and libvirt.
I will talk about some of the basic patterns for using Augeas to performsurgery on configuration files, share some tips on how to get the most outof its tree structure, and how to use it to perform idempotent changes. Iwill also talk about a few areas where Augeas can be improved, and whereit's use could be simplified.

It can be usedbasically everywhere, from embedded devices like phones, TVs or drones todesktop applications or on huge server farms.
This talk will focus on how and why Rust looks like the perfect programminglanguage for evolving GStreamer and provide a safer but still performant andeven more productive development environment than C.Both GStreamer application development in Rust, and GStreamer plugindevelopment will be covered. What is possible today already, for whichapplications can Rust be perfectly used already and which parts are stillmissing? How does it feel like to write an application in Rust compared todoing it in C? And how and why would one write GStreamer plugins in Rust toextend the framework and all applications with support for new codecs, filtersor anything else?
Afterwards there will be a short outlook into the future of Rust in theGStreamer project itself and for GStreamer application and plugin development.

We work on low-temperature nanophysics and transport spectroscopy, typically measuring current through experimental chip structures. That involves cooling and temperature control, dc voltage sources, multimeters, high-frequency sources, superconducting magnets, and a lot more fun equipment. A desktop computer controls the experiment and records and evaluates data.
Some people (like me) want to use Linux, some want to use Windows. Not everyone knows Perl, not everyone has equal programming skills, not everyone knows equally much about the measurement hardware. I'm going to present our solution for this, Lab::Measurement (see also https://www.labmeasurement.de/ ). We implement a layer structure of Perl modules, all the way from the hardware access and the implementation of device-specific command sets to high level measurement control with live plotting and metadata tracking. Current work focuses on a port of the entire stack to Moose, to simplify and improve the code.

If one disk or object-server fails then its data is always available on other object servers. Swift is able to apply this principle to not just disks and object servers but also independent availability zones and regions. This enables the deployment of so-called Global Clusters which provide a single object namespace spanning multiple geographically dispersed data-centres, each offering independent local access to object data.
This talk will describe some of the mechanisms that Swift provides for configuring and optimising Global Clusters. We will briefly describe how Swift's consistent hashing Ring maps objects to object servers and how that mapping algorithm can be configured to distribute copies of each object across data-centres. We will show how Swift's read and write affinity settings can be used to optimise WAN traffic in a Global Cluster. Finally we will discuss some of the challenges we faced when implementing Global Cluster support for erasure coded objects, and how those were overcome by enhancements to the Ring and the erasure coding write path.

Query languages like openCypher, implemented in systems like Neo4j, SAP HANA Graph and Redis Graph, allow the intuitive definition of graph patterns including structural and semantic predicates.
For now, graph query languages are most prominent in graph database systems such as Neo4j. However, we think that many systems can benefit from having such a language in their toolbox. One of these systems is Apache Spark, which is one of the most popular open source frameworks in the context of distributed processing of large data volumes within complex analytical workloads.To bring the benefits of Cypher from the graph database realm into the world of Big Data, we at Neo4j started developing Cypher for Apache Spark (CAPS). CAPS is primarily focused on graph-powered data integration and graph analytical query workloads within the Spark ecosystem. In addition, CAPS is our testbed for Cypher language extensions as specified in the openCypher project; for example, multiple graphs, graph transformations and construction, and query composition.
In our talk, we want to motivate use-cases for CAPS and give an overview of new querying capabilities which we demonstrate using Apache Spark and Apache Zeppelin. Furthermore, we briefly present the internal architecture highlighting the main differences between Neo4j and CAPS.

The situation for HotSpot developers has also improved over the years:- the HotSpot build system was converted to the "new" build system- a proper unit test framework for C++ code (googletest) was added- debug symbols are no longer zipped by default- the JDK and HotSpot JTReg testlibraries were combined into one
This talk will show how all these changes make the OpenJDK developerexperience a lot smoother. The speakers will also share their personaltips and tricks on how to work even faster on OpenJDK!
We also realize that the OpenJDK developer experience is far fromoptimal, and would therefore like this talk to initiate a discussion onwhat could be improved and how people can get involved.

One of the major recent additions has been the ability to group together sets of users and rooms into 'Communities' - equivalent to Slack Teams or Discord Servers, which give a way for existing projects and communities to give their users a much more focused and friendly environment for decentralised communication with Matrix. In this talk we'll explain how Communities (aka Groups) work, how they're implemented, and how FLOSS projects in particular are using them and other recent features to escape the centralised tyranny of proprietary alternatives!

Rust is considered a mature system language that provides strong warranties about memory access (and more) without sacrificing runtime speed.
Multimedia libraries are plagued by classes of bugs that Rust actively prevents at compile time, thus this talk is about leveraging Rust to have a multimedia framework that is nice to use and at the same time more trustworthy.

GeoPandas (https://github.com/geopandas/geopandas) extends the pandas data analysis library to work with geographic objects and spatial operations.
Pandas is a package for handling and analysing tabular data, and one of the drivers of the popularity of Python for data science. GeoPandas combines the capabilities of pandas and shapely (python interface to the GEOS librabry), providing geospatial operations in pandas and a high-level interface to multiple geometries to shapely. It combines the power of whole ecosystem of geo tools by building upon the capabilities of many other libraries including fiona (reading/writing data with GDAL), pyproj (projections), rtree (spatial index), ... Further, by working together with Dask, it can also be used to perform geospatial analyses in parallel on multiple cores or distributed across a cluster. GeoPandas enables you to easily do operations in python that would otherwise require a spatial database such as PostGIS.

This talk shows how to monitor legacy Java applications with Prometheus. The goal is to have Prometheus as a central monitoring tool that integrates both, modern cloud-native applications as well as legacy Java EE applications.

Many of them contribute to free and open source software, and some of them publish their own free and open source software. All of this is good, and should be encouraged to continue.
In addition to that, though, many large companies have philanthropic arms; charitable foundations either operated by the company or closely aligned with the company, and primarily funded by the company. These foundations generally have focus areas, which include almost every conceivable charitable cause except... free and open source software!
This presentation will talk about Bloomberg's journey to add software philanthropy to its global charitable contributions, including the mundane aspects of running volunteer coding events, soliciting mentors/leaders to participate, organizing employee (and non-employee) participation, and others, but also how this type of philanthropy can be included in 'employee giving' and similar programs. Anyone who runs an Open Source Program Office, or similar group, within a company that also has a philanthropic arm should consider including free and open source software contributions in their plans, and this talk will help you get started.

WhenKhronos published the first release of Vulkan, almost 2 years ago,shaders used a binary format, called SPIR-V, originally developedfor use with OpenCL.
That means that the two major public 3D graphics API were usingdifferent shading languages, making porting from one to the other morecomplicated. Since then there were efforts to allow making thiseasier.
On July 2016, the extension ARBglspirv was approved by Khronos,that allows a SPIR-V module to be specified as containing aprogrammable shader stage, rather than using GLSL, whatever the sourcelanguage was used to create the SPIR-V module. This extension is nowpart of OpenGL 4.6 core, making it mandatory for any driver that wantsto support this version.
This talk introduces the extension, what advantages provides, andexplain how it was implemented for the Mesa driver.

This is what I'll be demoing in this short talk, using a small piece of software that uses the LXD migration API to stream a system over the network to a remote LXD server, turning it into a container.

Tired of reinventing the wheel by implementing drivers for firmware again and again? Not with LinuxBoot!
What?LinuxBoot is a firmware for modern servers that replaces specific firmware functionality like the UEFI DXE phase with a Linux kernel and runtime.
Why?LinuxBoot improves boot reliability by replacing lightly-tested firmware drivers with hardened Linux drivers.LinuxBoot improves boot time by removing unnecessary code, resulting in a 20x faster boot time (typical value).LinuxBoot allows customization of the initrd runtime to support site-specific needs (both device drivers as well as custom executables).LinuxBoot and its precursors are a proven approach for almost 20 years in military, consumer electronics, and supercomputing systems – wherever reliability and performance are paramount.

To find the latest proven software one has to look across the Atlantic Ocean, where a suite of specialised open spatial solutions is emerging. For us in Europe this creates opportunities to innovate traditional mapping services into higher value added business information provision.Meet the innovative projects from across The Big Pond such as GeoGig (versioning/data history), GeoMesa (database) and GeoWave (distributed storage). Building upon Hadoop, Spark and Cassandra we are able to integrate the latest technology for robust and affordable geospatial solutions, to deploy Big Spatial Data answers to Big Data challenges.

Because of performance requirements of modern workloads,the same could be said for container orchestration tools. But it is not thesame assignment - as VM and containers have varying degree of isolation, it isdone at different system layers. How could we bring device assignment toinfrastructure that handles both VMs and containers, such as KubeVirt?
The talk aims to* introduce KubeVirt, a Kubernetes add-on to manage virtual machines,* give overview of device assignment in Kubernetes and in VM management software oVirt,* present an idea of combining these two.

In the current state of the project, what we have is a remote controlled car, but with sensors that you would find on an autonomous vehicle such as IMU and distance sensors. The goal is not necessarily to implement the autonomous feature ourselves, but to allow users to do it by either modify the firmware or add and external computer such as a Raspberry Pi or OpenMV to to add autonomous driving features.
The hardware is open and was designed with FOSS tools such as Kicad and FreeCAD. It’s made of a PCB that act as the frame of the car, 3D printed parts, off the shelf parts from pololu.com (battery, motors, sensors) and and Crazyflie 2.0 nano drone. The drone (without its motors) is connected to the O’PAVES board using an extension port. This solution makes the platform easy to build because most of the very small electronic assembly is already done on the drone. The software is developed in Ada and also only uses FOSS tools like the GNAT compiler or the AdaDriversLibrary. The project is hosted on GitHub: https://github.com/adacore/opaves
In this 25 minutes talk I want to present the state of the project, explain how you can build and hack the platform and show some of the tools and techniques that we used to develop the project. I will bring one of the prototype with me and at least show a video demo if not a live demo.

Most applications need a stateful layer which holds the data. There are at least three necessary ingredients which are everything else than trivial to combine and of course even more challenging when heading for an acceptable performance.
Over the past years there has been significant progress in respect in both the science and practical implementations of such data stores. In his talk Max Neunhoeffer will introduce the audience to some of the needed ingredients, address the difficulties of their interplay and show four modern approaches of distributed open-source data stores.

The Modules project, also referred as Environment Modules, provides a shell command named module that simplifies shell initialization and lets users easily modify their environment during the session with configuration files called modulefiles.
The Modules project has a long history as its development was started in 1991. At that time, the concept of the module command was laid down to dynamically and atomically enable environment configurations during a shell session. Since then, this concept has become a standard practice, especially among the scientific community where people share same computing resources but all have a specific software and version requirement.
After an almost 5-year release hiatus, Modules with its version 4 is back into the environment management game. The intend is to further improve the modulefile standard and the module command capabilities, with proven concepts applied to similar fields like software package management.
After briefly explaining the root concept behind the module command, this talk will cover the major changes between versions 3.2 and 4 at both software and project level. Then focus will be put on some of the recent or upcoming new features:* virtual modulefiles* extend the module command at your site* sharing code across different modulefiles* dependencies management between modulefiles* new ways to query or change the environment state
The audience for this talk is anyone who is interested in user environment management. From the system administrator, who has to provide access to a software catalog, to the end-user of shared computing system, who need to juggle with different workloads combining software elements.

Its goal is to turn scientific kernels written in Python into native modules that runs much faster, take advantage of SIMD instruction units, multi-cores, get rid of the GIL without sacrifying high-level programing. As such it understands a strict subset of the Python language, keeping 100% backward compatibiliy with the original language.
Looks cool? It is. But the target niche is small (high performance computing in Python and several great tools already exist (Cython, Numba).How have Pythran survived in the OSS jungle for 6 years while gathering a small but living community?

Clang SA works well with function call within a translation unit. When execution reaches a function implemented in another TU, analyzer skips analysis of called function definition. For handling cross file bugs, the CTU analysis feature was developed (Mostly by Ericsson people)[2]. The CTU model consists of two passes. The first pass dumps AST for all translation unit, creates a function map to corresponding AST. In the second pass when TU external function is reached during the analysis, the location of the definition of that function is looked up in the function definition index and the definition is imported from the containing AST binary into the caller's context using the ASTImporter class. During the analysis, we need to store the dumped ASTs temporarily. For a large code base this can be a problem and we have seen it practically where the code analysis stops due to memory shortage. Not only in CTU analysis but also in general case clang SA analysis reducing size of ASTs can also lead to scaling of clang SA to larger code bases. We are basically using two methods:-
1) Using Outlining method[3] on the source code to find out AST that share common factors or sub trees. We throw away those ASTs that won't match any other AST, thereby reducing number of ASTs dumped in memory.
2) Tree prunning technique to keep only those parts of tree necessary for cross translation unit analysis and eliminating the rest to decrease the size of tree. Finding necessary part of tree can be done by finding the dependency path from the exploded graph where instructions dependent on the function call/execution will be present. A thing to note here is that prunning of only those branches whose no child is a function call should be done.

However, it may be challenging to create and maintain such a policy per container. Moreover, a dynamically configured and unprivileged access control may better fit to container needs.
In this talk, we present a Linux Security Module (LSM) proposal called Landlock, leveraging eBPF to create flexible access-control rules. Landlock can be used as a new security layer, composing with namespaces, cgroups, seccomp and other LSMs, to sandbox applications and containers. We highlight the last Landlock patchset (v8) which brings a new way to restrict access to files.

Technical debt can be incurred with statistical and machine learning algorithms that require a highly specialized knowledge of the algorithm at hand as well as the distributed engine / HPC library which the method has been written against. The Apache Mahout project presents a highly modular stack which introduces levels of abstraction between the mathematical implementation of the algorithm (an R-Like Scala DSL) and the execution of the code. Users are able to interchange Apache Spark, Apache Flink (batch), and H2O distributed engines, as well as ViennaCL for OpenCL on GPU and OpenMP, and CUDA native solvers. Users can also port high level algorithms to new distributed engines or native solvers by defining a handful of BLAS operations.

BrickerBot is an example of a recent malware strain attacking connected devices and causing them to “brick,” making an electronic device completely useless in a permanent denial-of-service (PDoS) attack.
Additionally, the Mirai botnet consisted of connected printers, IP cameras, residential gateways, and baby monitors that flooded DNS servers. Mirai was behind the largest DDoS attack of its kind ever in October 2016, with an estimated throughput of 1.2 terabits per second. It leveraged these enslaved devices to bring down large portions of the internet, including services such as Netflix, GitHub, HBO, Amazon, Reddit, Twitter, and DIRECTV. BrickerBot’s goal appears to counter Mirai’s: Bricking insecure Linux devices so that malware such as Mirai can’t subjugate these devices in another DDoS attack. We will take an in-depth look at the anatomy of the attack.
We will then dive into basic some security hardening principles which would have helped protect against many of these attacks. Some of the fundamental security concepts we will cover include:
Closing unused open network portsIntrusion detection systemsEnforcing password complexity and policiesRemoving unnecessary servicesFrequent software updates to fix bugs and patch security vulnerabilities

After the initial collection and packaging of the CCSC, its provision imposes a burden that may persist for a very long time. Ensuring that the CCSC is always available is not a simple matter, especially considering that the original development team might change structure, people might be replaced or change roles, legal entities may disappear, etc.
In this talk we will present the possibility of using Software Heritage, an independent, non-profit third party, in order to outsource CCSC provision. As part of the exploration, we will review the legal obligations in popular copyleft licenses, explain the burden of long-term CCSC hosting, describe the hosting infrastructure in place, and propose a publishing workflow that might help FOSS producers painlessly comply with the licenses.

The goal was to run several "pots" on my laptop to serve my needs and, at the same time, to learn how to manage them efficiently, especially in term disk usage. Instead of using/extending existing tools, like ezjail or iocage, I decided to reinvent the wheel and to write myself a new tool.After some time, I realized that making pot more generic and available to everyone could be a good idea and that's what I intend to present.I also show some interesting use cases and, hopefully, a live demo.

It tightly integrates MySQL Server, Group Replication, MySQL Router and MySQL Shell providing an easy-to-use full stack solution for HA.
MySQL Shell main goal is to provide a natural interface for all 'DevOps' tasks related to MySQL, by supporting scripting with development and administration APIs. To allow an easy and straightforward configuration and administration of InnoDB Clusters, the Shell provides a scriptable API - the AdminAPI. This API hides the complexity associated with configuring, provisioning and managing everything without sacrificing power, flexibility or security.
Join this session to understand the key points of MySQL InnoDB Cluster and to learn how to use the Shell and the AdminAPI to configure and manage InnoDB Clusters.

Babelfish aims to be a universal code parser that scales. Native parsers provided by each language ecosystem are used to get a native AST. This AST is then converted to a language-independent format that includes universal annotations for language features, which allows both a generic language-independent analysis and a more detailed language-specific analysis.
Language drivers are built on top of containers to allow easy deployment of many different languages in a generic way. An SDK is provided to develop these drivers, providing the annotation language, conversion tools, etc. A server is in charge of handling the different drivers, language detection, scaling the number of running instances, etc. Finally, libraries and clients for different languages are provided to give language analysts the needed foundation to be able to write the code analysis tools they want.
In this talk, we want to explain in more detail the architecture and components of Babelfish to reach both language analysists interested in building tools on top of it and potential contributors to the project.

The evidence is already out there—a connected car can produce up to 5 terabytes of data hourly, an oil and gas drilling rig can produce 7 to 8 terabytes of data daily. Waiting for all of this data to be sent to the cloud and acted upon won’t cut it for many applications in industrial or consumer domains. Even for edge analytical applications, conventional big data architectures that involve forwarding everything to the cloud to be stored and analysed doesn’t make sense—what you likely need are Machine Learning and streaming analytics capabilities at the edge.

For coarse grained regular parallelism, load balancing works with one single job queue. For finer grained and irregular parallelism, work stealing balances the load with multiple job queues. The programming concepts will be illustrated with examples of algorithms in polyhedral geometry. The demonstrated code belongs to the free and open source PHCpack, at https://github.com/janverschelde/PHCpack.

The property of anonymity itself is more than just providing an encrypted connection between the source and the destination of a given conversation. There is in fact a lot of information that can be still learned by just observing encrypted communications. Anonymity is a broad concept, and it can mean different things to different groups. The main advertised property of the Tor network is that it provides strong anonymity given a variety of people using the network. The Tor network itself is only a part of what Tor is. Tor also provides privacy at the application level through the Tor Browser. This talk is going to present what Tor is and how it works. We are also going to present new features we have been developing lately. Finally we are going to explain how you can build applications that use Tor.

It will cover a wide range of topics from designing a printed circuit board with KiCAD to software support and integration with the popular open source home automation platform Home Assistant through the machine-to-machine protocol MQTT.
We will review the designing process of open source hardware embedded devices that control 12V RGB LED strips and collect data from I2C sensors for light, temperature, humidity, color and gesture recognition. We will compare and highlight the differences between the software implementation of MQTT client with brightness and color control of the lights using pulse-width modulation (PWM) on embedded Linux through an add-on board for Raspberry Pi and a device powered by the low-cost microcontroller with Wi-Fi ESP8266.
The talk will also provide information about open source hardware licenses, KiCAD getting started guidelines, tips for avoiding common hardware pitfalls and mistakes. Furthermore, we will discuss the challenges of prototyping and low-volume hardware manufacturing. The talk is appropriate for anyone interested in combining open source hardware with free and open source software. No previous knowledge is required. The presentation will try to encourage more people to grab the soldering iron and start prototyping entirely open source products.

It uses just-in-time compilation to get a performance level that is comparable to C/C++. It was designed to overcome the “two-language problem”, where a proof-of-concept in a high-level language needs to be translated to a compiled language by specialists to get the required performance. In this talk, the main features of the language will be highlighted from the perspective of a “convert” coming from C++ and with a focus on scientific programming aspects. As an application, arrays and the work on making parts of the Trilinos library available will be discussed.

So far, Linux always assumed the master role. In v4.13, Linux finally gained slave support.In this presentation, Geert will talk about adding SPI slave mode support to the existing SPI subsystem, and using a Linux system as an SPI slave. He will show what makes SPI special, and cover possible use cases and limitations of Linux-based SPI slave mode.Finally he will demonstrate how he modified Linux to add support for SPI slave mode.

Monero is evolved from CryptoNote, which is a completely independent code base from Bitcoin emphasizing privacy as opposed to Bitcoin's transparent blockchain. Like Bitcoin, Monero is fully open source. The project is driven entirely by volunteers. The Monero team has developed further innovations over the CryptoNote code base making it the most private cryptocurrency ever, and the first in the world with true fungibility.

Ruby fragments that describe how puppet can interact with resources in our systems. This has been part of puppet's core code since the very first days, but adoption has been hampered by the API being tied up deeply into puppet's internals.
The new Resource API project provides a coherent, and decoupled way to define new resource types. It is based on Puppet4+ data types, making validation a breeze. The backend provider is a simple ruby class with well-defined API requirements. Together, this makes the new providers easier to read, and write, as well as easier testable.
In this talk I'll give an overview of the new API, and how to write providers using it. Basic Ruby and Puppet knowledge recommended.

We're able to deliver the best product to our customers faster than ever before. At the same time, nobody wants to sacrifice quality or the pace of production. We know a lot about software quality assurance, and we have tools to produce higher quality software. Could we use them to ensure the quality of the open-sourced solutions as well?A couple of years ago, I created a tool called Ossert. An experiment to asses the quality of every Ruby gem. While developing Ossert, I thought a lot about the quality of the open-source software.
In this talk, I'll talk about my experience in making the quality of OSS measurable: how could it correlate with project maturity stage? The patterns of its community behaviour? Finally, I'll share the set of practices I created to asses the quality of open-source development processes.

A Network of Namespaces (NoN) interconnects network namespaces running ondifferent hosts as if they were on the same (virtual) Local Area Network. It ispossible to set up and maintain NoN using VLANs, veth, kernel bridgedefinitions,… but it would be a daunting work for system administrators.
VXVDE and VXVDEX implement zero-configuration NoN. Starting a namespaceconnected to a NoN it is as simple as typing a command like: “vdens vxvde://“.This new approach is fast (about the same performance figures of VXLAN’s kernelimplementation) and it runs on vanilla Linux kernels.
Several protection features can be added to support different usage scenarios:VXVDEX provides NoN with access control, and the agnostic encryption (meta)plugin can protect any kind of VDE implementation from eavesdropping.

Well established tools are not well integrated for the use cases needed and it is easy to detect gaps in the overall toolchain for dedicated tasks. Instead of solving these challenges alone, wasting lots of money on the path, the Bosch division together with partners from the industry but also from other domains builds up a community to solve the toolchain challenge together in the OpenADx initiative. With this the partners expect a substantial saving on toolchain costs but also a better integration within organization and especially at the interfaces between cooperating organizations. This talk will present the approach and the current state of the community.

How similar are two hurricane trajectories? In the heart of both questions there is distance computation. In this talk we will discuss distance computation in Boost.Geometry, the library that is currently being used to provide GIS support to MySQL.
We study and implement several families of algorithms for distance such as iterative, series approximation, elliptic arc length, flat earth approximation, spherical. We show particular examples using those algorithms to compute distance between points or polygons. Finally we compare them w.r.t. performance and accuracy. Our ultimate goal is a distance function that given a user defined accuracy utilize the most efficient algorithm.
We sum up by briefing next steps of development in Boost.Geometry and ideas for GSoC'18.

As I moved from software development to community outreach and marketing, I learn more about how design affects every aspect of the product and promotion. To top it off, I've encountered many different understanding of what openness is, especially when related to design. In this presentation I'd like to share some observations and lessons learned, and hope it can help designers, especially open source designers, navigate and negotiate the diversity in cultures and expectations.

But instead of trying to predict the various ways something might go sideways right before release and crafting dashboards to prepare, what might it look like to use answers about our system to figure out what to build, and how to build it, and whom for?
Observability is the practice of understanding the internal state of a system via knowledge of its external outputs -- and is something that should be built into the process of crafting software from the very beginning.

Unfortunately not all parts of the project have got attention equally. A lot of new and missing functionality can be found in so-called Out-of-Tree modules (OOTs).The struggle to add changes to OOTs which are incompatible to the GNU Radio core is real. The GNU Radio runtime needs some fresh ideas so new development with GNU Radio will be possible and rewarding. This presentation will try to give an quick overview about the current structure and inner workings of the GNU Radio runtime and take a dive into how a new runtime can be implemented to make GNU Radio future-proof.

Various resources of a Ceph cluster can be managed and monitored via a web-based management interface. It is no longer necessary to be intimately familiar with the inner workings of the individual Ceph components.
Any task can be carried out by either using openATTIC’s clean and intuitive web interface or via the openATTIC REST API.
openATTIC itself is stateless - it remains in a consistent state even if you make changes to the Ceph cluster's resources using external command-line tools.
If you're interested in the dramatic changes and improvements we made since last year and you want to take a look at the newest version of openATTIC, this is the right talk for you.

Intended for use not just by the Docker engine as a lower layer container runtime and management layer above an OCI compliant executor, the expectation is that Kubernetes will use containerd as well as other projects that need a straightforward, embeddable container runtime without vendor control or opinionated behavior.
This project update will overview how we arrived at a "containerd 1.0" feature complete state from the original containerd implementation, and how it is being embedded and used in various projects like "cri-containerd" for Kubernetes and the recent Docker engine releases. We'll also look at the ease with which containerd can be embedded via its client library to offer container lifecycle management to any broader application.

Packaging from Pots to Software DESCRIPTION:Big changes are well underway in how software gets packaged and delivered. But even relatively modern takes on packaging goods and services for sale and consumption go back hundreds of years. In this talk, I'll take you on a whirlwind tour of packaging. What forms has packaging taken? What problems were being solved? What kinds of trade-offs need to be made? What lessons can we learn? How has packaging evolved from the utilitarian to the experiential?
And, critically, the trade-offs between prescriptive proprietary bundles and the sort of open-ended unrestricted choice that open source software can enable.

Some modules saw over 100 versions, because my workflow was: release often. This works very well when you work alone and regularly with your modules. Recently, my needs shifted a little. There are some (minor) advantages to use GIT. And once that transfer is made, the step to GitHub is made. Everyone has his/her own way of releasing, with tricks to improve the process. I will demonstrate how my process works and how I changed my workflow. It will demonstrate how I load my whole history into git and github with little effort.

It has a fine-grained hosts selection mechanism that allows to dynamically query multiple backends and combine their results. In addition to some built-in backends such as PuppetDB, SSH known hosts files, OpenStack API, it's possible to plug-in external backends. The current transport layer is SSH, although additional transport layers could be easily added. There are multiple execution strategies available and fine-tunable to suit different orchestration requirements. The executed commands outputs are automatically grouped for readability.The talk will describe the reasons that led us to the development of Cumin and its features and show its current usage at the Wikimedia Foundation for automation and orchestration.

Traditional scalar instruction sets have been augmented by extensions borrowing techniques from super computers in the form of SIMD or Vector processing instructions.
In the world of virtualisation these new instructions offer a number of new challenges. From efficient emulation for code generating JIT's such as QEMU to increased latency when multiplexing multiple machines under KVM.
This talk will briefly examine the history of SIMD instructions before introducing ARM's innovative Scalable Vector Extensions. We will then discuss the challenges involved in virtualising them both in software and hardware alike.

The clear downside is development time: it can take several months or longer to produce a working, optimized unikernel, and up until now, the process needed to be repeated for each target application. There was no shared research and development on the building and creation of unikernels.
In this presentation we will introduce Unikraft, a new, open source Xen Project sub-project under the auspices of the Linux Foundation that seeks to automate the development process for unikernels. Unikraft decomposes operating systems and libraries into elementary modules called libraries (e.g., schedulers, memory allocators, drivers, filesystems, network stacks, etc) and then allows users to quickly pick and choose, through a menu, which components to use when building a unikernel. Once done, Unikraft builds one image per target “platform” (e.g., Xen, KVM or Linux user-space), severely reducing unikernel development time. We will show a brief demo on how to use Unikraft, and cover the basics of the system including how to contribute to it.

DESCRIPTION:There's a lot of pressure from the US (and some of it's allies) to "harmonize" with American ideas about patents and copyrights. The response by different nations has been wildly different -- some have chosen to play along while others have chosen to resist. What makes sense for one country won't make sense for another and it's all in the details. This talk examines existing legal patterns, the state of local economies and varying trade relationships in an effort to survey what kinds of resistance are possible or effective.

DESCRIPTION:Traditionally HPC systems assume they are in a secure, isolated environment andas many barriers as possible are removed, in order to achieve the highestpossible performance. While these assumptions may still hold for traditionalsimulation codes, many HPC clusters are now used for heterogeneous workloads.Such workloads increasingly involve the integration of input data from a varietyof sources, notably in the life sciences. Scientists are now operating at thepopulation scale, where datasets are ultimately derived from real people. Inthis talk we discuss some of the restrictions placed on the usage of suchdatasets, how those restrictions interfere with the goal of high performancecomputing, and some alternative strategies that meet the data requirements whilenot hobbling the speed of analytical workloads.

Initially the OPNFV CI was based on the consumption of stable artifacts, including stable versions of OpenStack. Developers were not able to work with master versions, causing lack of testing and delay on delivering projects.
Cross Community CI project (XCI) enabled testing based on master versions of the different upstream components (OpenStack , OpenDaylight...). This caused to significantly cut the time of development and identify bugs earlier.
In this talk we will introduce that concept, and we will also explain the tooling used to achieve it (bifrost, openstack-ansible, ansible-opendaylight), showing how a deployment goes from end to end, how to reuse this project for your own needs, and how to start integrating your own project into XCI if that fits into the scope.

Within one application ecosystem?Having a C/C++ application to natively support both Unix/Linux and Windows operating systems is known to be a mess for both the application's Source Code and Build System. Nevertheless, developers still are expected to provide exactly that - depending on the nature and lifetime of an application. This talk is about how SSI Schäfer IT Solutions is achieving the goal of concurrently providing support for both operating system worlds within one single C/C++ application ecosystem, which was originally targetting the Unix world only.

G-CORE is a graph query language proposal developed by Linked Data Benchmark Council (LDBC). It is a closed graph query language that includes graph pattern matching, inclusive extended regular path expressions, graph construction (graph projection and graph aggregation), and (weighted) shortest path finding. The query language queries graphs and returns a graph. Hence, it supports views and correlated sub-queries, which have proven their worth in the relational databases. To ensure that the query language is practically usable on large data, G-CORE builds on previous complexity results and carefully select useful features, but restricted in such ways that the resulting language is polynomial in data complexity. As such, G-CORE connects the practical work done in industrial proposals with the foundational research on graph databases; in fact, it can be considered as a bridge between these two worlds.

We showed off the work of individuals and small studios doing exciting work with F/LOSS tools. While exciting things are happening in the world of F/LOSS design, the perception of F/LOSS graphics tools as somehow less-than or other-than the “industry standard” for graphic designers persists. This presentation looks at problems of F/LOSS adoption, especially for graphic design. It asks the question “What kinds of ecosystems do we need to have to successfully do Libre Graphics (including F/LOSS, Free Cultural licenses, and Open Standards) in professional contexts?”

All the data that the computer processed always passed through the main memory in one way or the other and the code running on the CPU manipulated with the data, directly on indirectly. Even DMA controllers, co-processors, GPUs and intelligent NICs were used just as slave peripherals, although with some degree of computational off-loading in the recent years.
One of the reasons for keeping the same basic architecture despite its drawbacks such as the ever-widening memory barrier (i.e. the difference between the latency of the CPU and the RAM) was arguably its conceptual simplicity. However, trends for a major change in the status quo are finally emerging into the mainstream. These new architectures, often called data-centric computing or near-data processing, propose to turn an ordinary computer into a distributed system where the distinction between the CPU, main memory and peripherals is much more blurry. Components such as individual DRAM chips, flash memory chips and NICs should have autonomous computing capabilities and the possibility to interchange data between other components without the involvement of the main CPU.
This talk will present a brief overview of the concepts and discuss the consequences for operating system designs, especially regarding microkernels.

Each has its unique structure, stakeholders and requirements. Given this reality, often successfully extracting valuable insights from a software system requires software analyses tailored to the context of that system. This is the main goal of Moose, an open-source platform for software and data analysis: empower programmers to craft custom analyses cheaply. Instead of providing predefined tools, Moose focuses on moldable tools that enable programmers to create their own analyses. We can measure the cost of a custom analysis in terms of minutes, instead of days. This demo will show ways in which Moose can enable custom analyses. For example, we'll look into extracting dependencies between components in Angular and investigate the usage of deprecated classes in Java.

I started the project in 2010, and to enable better support, I joined GnuPG development. I had a talk in FOSDEM2012. It wasn't go well as I expected in 2012.
I needed to design my own free hardware design for reference hardware. That's FST-01.I needed to design and implement True Random Number generator of my own. That's NeuG.
For better control of hardware resource, I develop a thread library named Chopstx.
In 2016, at OpenPGP.conf, I realized that people generally hesitate new hardware. Thus, in 2017, I modified Chopstx so that it can run on GNU/Linux as emulation. Now, a user can run Gnuk on normal GNU/Linux as an emulation, by USBIP, without real physical hardware device.
In short, my talk is: Everything is free software (firmware on the device, driver on host), and hardware has free hardware design, but that's not enough. Emulation is useful, hopefully.

What started as a network of nodes in people's homes turned into a network of server farms largely owned by a handful of tech giants. Flaws in the internet's design and implementation allowed for an online world to form where a few large services control nearly all users. Social networks don't put you in touch with your friends. They put you in touch with a server that helps with that... at the cost of privacy and community.
Urbit aims to solve this and many other problems by providing a decentralized network of personal servers. These come with a personal identity and an operating system that provides an immutable global namespace and all the infrastructure needed for making decentralized applications.

DESCRIPTION:Accessibility in free software has been much improved between 2004 and 2009thanks to Sun, which massively invested for it. Since it has disappeared, bigfree software projects have experienced many regressions in this matter. Someof their maintainers consider that there is not enough money to deal with thematter.
Given the complexity of code such as Libreoffice, and given thestatus of accessibility of software in modern society, it becomes impossibleto invest millions of euros to pay for someone who would fix current bugsand track future ones in millions of code lines, through hundreds of commits,and permanently. All the more since beyond this task, a paid expert shouldrather work about improvements of assistive technologies themselves and pipes(at-spi, atk), instead of fixing miscoding of unaware developers. So, to hopea free and accessible software, major projects need to take responsibility ofthis. Non-regression tests could be a way to make this duty lighter, even if nota complete solution. What kind of tests could be set?

There are four main ways ofextracting and processing an LTTng trace, and each of them addresses adifferent use-case. In this presentation we will demonstrate these modes andpresent real-world situations where they can be used. If you already know howto use LTTng you will learn new ways this tool can help you, and if you don't,you will probably discover a new way to address these complex problems.
The modes we will demonstrate are: post-processing mode (default), snapshotmode, live mode and the new rotation mode.
All of these modes have their pros and cons in a context of monitoring andcloud and we will be happy to discuss with the crowd to see how to address

She's making her mother's brisket recipewhich starts by cutting the ends off of the roast. Her husband asksher why she cuts the ends off. She says she does it because that's theway her mother always did it. She asks her mother and her mother says"That's the way your grandmother always did it". She asks hergrandmother and her grandmother says "That's the only way it would fitin my pan". There's a lot of folklore and myth surrounding Javagarbage collection performance, most of which is obsolete, irrelevantto your application, or was never really right in the first place.
So how do we evaluate a GC algorithm? We can measure various metrics: end to end run time, maximum pause time, average pause time,percentage of the cpu given to the Java threads, memory footprint,micro benchmarks, ... This talk will focus on ten (give or take)metrics/tools we can use to evaluate garbage collection performance.This isn't a comparison of OpenJDK collectors, it's a discussion ofwhat characteristics are important in a good garbage collector and howto measure them.

In the strict form, the assertions are checked at compile-time, but in this presentation I will focus on the more common, less strict, form, where at least some of the assertions aren't checked until run-time.

But in order to actually get this low energy usage the operating system needs to make efficient use of the hardware. Linux supports a lot of hardware power-saving features, but many of them are disabled by default because they cause problems on certain devices or in certain, often corner-case, circumstances. This talk will describe and look into recent efforts to enable more power-saving features by default in such a way that this will not cause regressions. The end goal of these efforts is to shave of at least 2 watt of the typical idle power-consumption of 6-9 watt for recent (Hasswell or newer) laptops. The goal is to achieve this saving on an OOTB Fedora Workstation install without the user needing to do any manual tweaks.

One way to address that is by allowing queries to be processed by more than one core at a time; which the project started to enable with 9.6, extended a lot in version 10, with significant additional features expected in 11. But that does not address the efficiency / economics of overall query execution.
This talk will focus on increasing the efficiency of query execution by just in time compiling parts of queries. That is, instead of having roughly interpreter like code to execute the queries, emit native code doing precisely the work needed for a specific query.
The current goal of the project is to use LLVM to perform JIT of two main parts of query execution:
and to integrate as much of that work as possible into PostgreSQL 11.
We'll discuss:
Depending on the available time, we'll also discuss possible future avenues for optimization.

It is vital to monitor systems for malfunctions that could lead to users' application service disruption and promptly react to these fault events to facilitate improving overall system performance and user experience.The relevant events and metrics must be reported to higher level fault management systems, to detect violations (and enforce SLAs), as well as faults or degradation in the performance of NFVI resources.
Additional statistics facilitate more resilient and performant telco/NFV clouds.By exposing system statistics to collectd, there is more data available, which can be used for monitoring, performance analysis, fault detection, failure prediction, etc. using OPNFV, action can then be taken to negate the effects of any faults in the deployment.

However, as trendy as it may turn, there is no viable Electronic Design Automation (EDA) toolchain that allows to design ICs in 3D. Our work aims at developing tools that could be used in standard 2D EDA chains to deal with 3D ICs. Such tools will automatically transform any 2D design into an optimized 3D architecture by extracting a graph from the DEF file coming out from 2D synthesis and place&route flow. Afterward, this graph can be partitioned automatically using state-of-the art graph partitioning tools.
In order to create the toolchain, we developed a custom DEF parser to answer specific and limited needs that existing solutions such as Verilog-perl or PyVerilog did not allow. The software scans the DEF to find all the gates, pins and nets in the given design. When analyzing nets, it also parses the routing information to determine the total length of the net, which will be needed in the partitioning phase.
In parallel with the DEF parsing (design input), the LEF technology file (technology input) is also parsed to fetch the characteristics of the gates that will be used later on in the clustering and partitioning steps.
Once the design has been parsed, it can be clusterized to reduce the problem complexity and the output is formatted to extract the underlying hypergraph.The extraction makes use of standard Python structures such as dictionaries in order to quickly find links in the design and establish references between the vertices (i.e. clusters or gates) and edges (i.e. nets). When building the hypergraph, some metadata are linked to each vertex/edge (e.g. area, power, total length, total connections) to later set their weights that will be needed in the partitioning phase.
As soon as the design has been converted into a hypergraph, it is formatted in such a way so that it can be fed to the hMETIS package. Using the weights sets extracted during DEF/LEF parsing phase, hMETIS partitions the graph. The output is processed into TCL directives that are then interpreted by a proprietary tool handling the 3D P&R, or they can be used to automatically partition the post-synthesis gate-level netlist and thus be used with any EDA flow, including the open-source ones.

Although these hurdles can be overcome with a reasonable amount of effort,for example by reading the project's documentation or following some basic tutorials,they turn out to be a showstopper for some people.Possible reasons include:
This can result in a significant amount of (potentially very useful) lost contributions...
In addition, project maintainers often lack the time required to process all incoming contributions.Doing so not only requires a visual review of the code changes, but also testing, enforcing code style requirements, providing feedback, etc.
In this talk, I will outline the extensive GitHub integration that has been implemented in EasyBuild,a framework implemented in Python for building and installing (scientific) software on High Performance Computing (HPC) systems.
The EasyBuild command line interface has been extended to add support for:
In addition a bot was implemented to automatically notify contributors & maintainers that the Travis CI build for a pull request is failing (which is not supported by Travis CI itself).
These features have been implemented by leveraging the GitPython library, the GitHub REST API, and the Travis CI API.
They have proven invaluable for both contributors (regardless of experience) and EasyBuild maintainers, by streamlining the contribution process.In addition, this has resulted in:
I hope this talk can motivate other projects (large & small) to implement similar features to simplify their contribution process, since this is a critical part of building a community around a software project.The EasyBuil features that are outlined can also be implemented in other projects, regardless of the programming language being used and the scope of the project.

Resource isolation is much different that security isolation. How do we make applications deployed in containers more secure? How do we apply existing tools like SELinux and AppArmor, and seccomp to our containers running in Kubernetes? How can we apply policy to our network and services to make sure applications only have access to what they need and nothing more?
Kubernetes provides the ability to secure containers, and secure access to the API. But it also has a flexible enough architecture to allow for applying network and service policy to various pods and services.
In this talk we will learn about the risks and attack surfaces and how to use tools like SELinux, AppArmor and seccomp to improve the security of containers deployed in Kubernetes. We’ll then go up the stack and learn how to apply network policy to containers to further improve security. Finally we will look at the Istio service mesh and how we can add authentication, mutual TLS, and access policies to whole services greatly reducing application attack surfaces.

In this presentation, we will discuss the various processing stages taking place on the LoRa PHY layer, including coding, whitening, interleaving, modulation and preamble detection. We will subsequently learn how hardware LoRa radios can be reverse engineered in order to build our own LoRa decoder with GNU Radio and software defined radios. The concept of PHY-layer fingerprinting will also be briefly explained, showing how we can identify individual LoRa radios using only their raw radio signals and a neural network. Finally, we will see how software defined radios can be leveraged to perform electromagnetic side-channel attacks on the AES encryption scheme, which is used by LoRa and various other wireless protocols. Such attacks enable the recovery of an unknown secret key given a set of known plaintexts and proximal measurements of the electromagnetic spectrum taken during the encryption process.

In reaching out to the India Shakti RISC-V team the opportunity presented itself to put a proposal to them of a mobile / embedded RISC-V 64-bit SoC that would meet their requirements: low cost, libre, and suitable for four markets: smartphone, tablet, laptop / netbook and embedded industrial purposes. Six years ago the author attempted to create an SoC pinmux: it took over two months. Learning from that experience and instead writing a python program to represent the pinouts, adding new test scenarios instead took about an hour each, including altering the pinouts to best match the new scenario whilst still maintaining access to functions needed for all other scenarios as well. Assuming the market assessments were correct, the design - which only requires a 300-pin BGA package - can be said to have been proven to successfully meet all four target markets. Crucially with this approach, potential customers can be approached with the preliminary design, for their input and feedback before committing huge sums to design and tape-out actual silicon.
The output of the python program is a simple markdown page that can be used, without alteration, as the Reference Documentation should the SoC ever be created. In addition to the pinouts, the source of the design inspiration and guides utilised in the design has also been documented, so as to provide not just Reference Schematics and parts that are easily available in the Shenzhen / China markets, but also a logical justification for the actual choice of interfaces in each of the target usage scenarios. Ultimately, it helps explain why low-cost embedded and mobile-class processors are designed the way that they are.
Also included is links to numerous sources of BSD-licensed and compatible LGPL-licensed hard macros (VLSI / VHDL) such as the ORSOC Graphics Accelerator, so that, if utilised, apart from the DDR3 hard macros (which the Shakti team plan to implement under a libre license) the entire SoC's full hardware-design source code is completely available under Libre Licenses. With absolutely no proprietary firmware required whatsoever it has the potential to be one of the world's first ever mass-volume mobile-class quad-core 28nm 2.5ghz embedded SoCs that will be entirely libre right down to the bedrock.

In the Ring-AllReduce architecture, workers are organized in a ring topology and communicate gradients updates without incurring in the communication bottleneck with the parameter server(s) that traditional distributed Tensorflow suffers from. Ring-AllReduce has been used by Facebook and IBM to reduce the training time on Imagenet from 2 weeks to ~45minutes/1 hour.Finally, we will show how you can recreate the popular game "Quick, Draw!" using HopsWorks and Tensorflow services provided the platform.

In particular, eBPF (extended Berkeley Packet Filter) programs, when attached to XDP (eXpress Data Path) hooks at the driver level, provide a fast in-kernel programmable data plane.
Because XDP is so low-level, the only way to move packet processing further down to earn additional performances is to involve the hardware. In fact, it is possible since kernel 4.9 to offload eBPF programs directly onto a compatible NIC, thus offering acceleration while retaining the flexibility of such programs.
Building the compatible NIC, and optimising the offload process are not trivial. The objective of this talk is to present the current state of eBPF offload, the challenges that have been overcome, and the ones that lay ahead.

It has drivers to support many different mice vendors and models. Clients, like the GUI application Piper, interact with the daemon via DBUS. The on-board settings include button-mappings, resolutions, and LED colors and patterns.
The vendors all use different protocols to configure the mice, and every mouse model must have a separate .SVG and configuration file. This talk will cover the steps to add support for a mouse. From reverse engineering the protocol, writing the driver for libratbag, and creating a .SVG to be displayed in Piper.
If you own an unsupported device then you can bring it to the conference, and we can look at adding support for it after the talk.

Your smartphone can be taken over remotely via WiFi. Opening media files remains an (unpredictable risk)[https://en.wikipedia.org/wiki/Stagefright_(bug)]. Despite all the effort put into mitigation techniques we don't seem to make good progress with the privacy and security of our mobile devices.
We present our vision of Componolit, an open-source platform for trustworthy mobile devices. Based on the Genode OS framework, the component-based system will provide strict isolation between apps, services and drivers. The platform will enable users to run arbitrary unmodified Android apps without giving up control of their devices. This is realized by trustworthy policy objects implemented and formally proven in the SPARK language.

The result of the compilation of Toro is an image that contains both the kernel and the application. The kernel image can be booted by all majors hypervisors Hyper-V, KVM, VMWare ESXi, and emulators Qemu, VMWare WorkStation, VirtualBox. In these environments, the application runs directly inside the kernel without the need of a general purpose operating system. In this talk, I will present recent experimentation in which the scheduler of Toro is optimized to reduce the CPU usage of a VM. It has been identified three cases in which the scheduler can be optimized to reduce the impact of idle loops. To validate these techniques, I will present the impact of the improvements on a live running Toro VM on top of QEMU and Hyper-V. Open questions are welcome throughout the session to discuss the benefits and drawbacks of this approach but also take-away lessons.

However, parsing by itself can (and should) be used out of the context of the Rust compiler: given the wealth of information that we can extract out of the code, we can do a lot of thing with it.
In this talk, we'll discuss several interesting applications for the Rust parser and the abstract syntax trees it produces, with practical examples of Mozilla bindgen (automatic generation of Rust library bindings based on C source code) and a Java binding generator written by the author for a large-scale open source library.

DTrace is a dynamic tracing tool that allows kernel and userspace tracing inoperating systems. It was first implemented for Sun's Solaris and later adoptedby other operating systems (Mac OS X, BSD). The Linux port is still ongoing.
In this talk, I would like to introduce the D language and its features. After abrief introduction the talk will focus on the architecture of the DTrace itself.Last part of the talk will be focused on the current status of the project.
DTrace is able to process data directly in kernel like eBPF. This allows us toperform some actions at the time an event has occured rather than during postprocessing of the records later in userspace. It allows also more precise selectionof events of interest.
It is possible to use DTrace in many use cases:
- A kernel hacker may precisely monitor the Linux kernel- A system administrator might use DTrace as an underlying technology for observing system behavior.- Participation in distributed tracing of complex scenariosI would like to show some real life examples how DTrace can be used to inspectrunning system or as source for external telemetric system.

The overhaul of the language and toolset starting in 2010 increased greatly the language subset, dropping in effect the need for separate grammar rules. Since then, SPARK has progressively adopted most of the Ada features, to a point where the last remaining non-SPARK significant Ada feature today is pointers. We have started work on including safe pointers in SPARK, borrowing the ideas of pointer ownership from Rust. So one can legitimately wonder what difference remains between SPARK and Ada.

It collects logs from many different sources, processes and filters them, and finally it stores them or routes them for further analysis. IoT developers can get started with it quickly, as its configuration language is similar to programming languages.

Understandably so, the compiler is known to not just catch what would in other languages become a run time bug, but also to be quite helpful. On top of that, the clippy project adds more than 200 additional lints, to catch even more errors, but also help guide users towards writing more idiomatic code. This talk is about the dream of automatically fixing many of these errors (based on compiler-provided suggestions) with rustfix.

The talk is drawn from my experience in leading the efforts around Go's package management, and the ongoing and evolving efforts to take language package management from an incidental thing that languages "just have," up to a domain of inquiry and engineering that is about programming languages, but also independent of them (much like compilers). Writing I have already done (https://medium.com/@sdboyer/so-you-want-to-write-a-package-manager-4ae9c17d9527) is considered by a lot of folks who work in this area to be foundational in this new phase; I hope to have a number of new thoughts and writing to present by the time FOSDEM 2018 comes around.

Each virtualization, cloud or container platform needs images as base. There are many (specialized) tools to generate them. If your organization needs a set of e.g. different distributions with the same packages installed and the same configuration, diskimage-builder might be the tool to choose: it can generate a wide range of different distributions (e.g. RedHat/CentOS, Ubuntu, Debian, OpenSuse, Gentoo, ...) as a virtual machine or even docker images for a couple of architectures. Images are known to run on a wide range of virtualization and cloud services, like OpenStack, VmWare, AWS EC2, OTC, KVM, docker (and even bare metal). diskimage-builder is highly configurable by means of 'elements': predefined and/or easy to write extensions.
The talk is a general (technical) introduction to diskimage-builder with a short in-depth chapter about the new block device layer like: images, loop devices, partitioning, lvm, mounting, fs, and fstab handling.

Aimed at schools and hobbyists, this open source project allows a new generation to experience the operation of a computer from 1948.
This talk will tell the story of the project, culminating in the three day extravaganza that was ChipHack 2017. I will be demonstrating all the components of the system: the delay line, the 3D printed peripherals and the processor core on FPGA. At the end of this talk, I hope you will understand more about this historic computer and be inspired to build your own EDSAC.

With the increase of Ethernet speeds from 40, 100 to200 Gbits/s, the need for high-speed raw Ethernet frame delivery toLinux user-space is ever increasing. In this talk, we present AFXDP(formerly known as AFPACKET V4) designed to scale to these highnetworking speeds through the use of true zero-copy, lock-less datastructures, elimination of syscalls and other techniques, while stillabiding to the isolation and security rules of Linux. AF_XDP iscurrently an RFC on the Linux netdev mailing list with the goal toget it accepted upstream.
In our evaluation, AFXDP provides a performance increase of up to 40xfor some microbenchmarks and 20x for tcpdump compared to previousAFPACKET (raw socket) versions in Linux. To illustrate the approach,we have implemented support for Intel I40E NICs and veth, but it shouldhopefully be easy to port to other NICs and virtual devices aswell. AFXDP is designed as an extension to the existing XDP supportin Linux so that XDP enabled devices will be able to use this. We alsoshow how SW networking libraries and SDKs such as DPDK can benefitfrom AFXDP to achieve increased robustness, ease-of-use and HWindependence.

DESCRIPTION:My talk will briefly review the major open data licenses including the differences between them and their interaction with free software licenses. Particular emphasis will be placed on thier application to databases.
There are only a few popular open data licenses with a focus on open database licensing, but there is very little guidance on the differences between them. This talk will explain the differences between them, why they exist, and when you might prefer one over the other. I will also discuss sui generis database right, why it exists and how is it different than the traditional copyrights.

In this talk, we explore the use and implementation of a Perl 6 server ("kernel") and how it interacts with various clients, such as a web client ("notebook") and a console client. We focus on distinctive aspects of using Rakudo Perl 6 in this environment, such as using the Perl 6 metamodel's introspection capabilities for autocompletion, discovery and entry of unicode operators, and using Perl 6's asynchronous primitives for concurrent operations. We also investigate possibilities for widgets, magics, and interactive data visualization. The talks was reschedules from 13:40 on the same day.

Duplication of effort, flawed funding models, and overall lack of project maturity has led to the failure of most free & open source software projects in the international development space. In this talk, we'll discuss the new Open Source Center at the Digital Impact Alliance (DIAL), an initiative of the United Nations Foundation. The Center's aim is to help increase those projects' maturity, quality, and reach -- with a goal of advancing an inclusive digital society using FOSS for the poorest places on the planet.

Modern graph databases are designed to handle the complexity but still not for the amount of data. When hitting a certain size of a graph, many dedicated graph databases reach their limits in vertical or, most common, horizontal scalability. In this talk I'll provide a brief overview about current approaches and their limits towards scalability. Dealing with complex data in a complex system doesn't make things easier... but more fun finding a solution. Join me on my journey to handle billions of edges in a graph database.

Design always carried the dominant ideas of the era and championed them, forming cultures along the way. Today's design is immensely influenced by Steve Jobs and his "Just Works" and "Automagically" mantras. While recognizing the significance of the democratization of technology, it was done in a way that for the first time completely hides the way things work from their users. In fact it goes to great lengths to lock users out of their gadgets.
Open source is about, among other things, freedom to study. In this spirit open source design isn't only about the sources of design documents, it's about facilitating the study of the inner workings: Let's create designs that are easy to use yet teach the user how the system we are designing works. Informed users will be able to better understand why a result is not what they expected, will be able to solve more of the possible problems, and the result is being happier both with the system and with themselves.

Want to avoid vendor lock-in and take advantage of the latest Postgres features and popular extensions not available in managed services from commercial vendors? Need to integrate your Postgres databases with existing monitoring and deployment tools? Interested in building your own database as a service?
In fact, you can do it with existing open-source components. Our talk is a story of how the database team at Zalando created company-wide database-as-a-service based on Postgres, Kubernetes and various open-source tools we developed on our own. We will share how we run hundreds of high-availability Postgres clusters on Kubernetes and automate routine operations using our open-source Postgres operator, providing developers easy-to-use tools to create, manage and monitor their database instances.

Devices connected via Thunderbolt can be DMA masters and thus read system memory without interference of the operating system (or even the CPU). Version 3 of the interface provides security levels in order to mitigate the aforementioned security risk that connected devices pose to the system. As result of this connected devices need to be to be authorized by userspace via a new kernel interface. The new kernel interface additionally supports updating the firmware of devices and the host controller.After an overview of the thunderbolt technology the specifics of the userspace enablement on GNU/Linux will be presented.

For AI to be truly ubiquitous, its cost and energy efficiency needs to be improved. With the recent developments made in algorithms and MCUs, we introduce a deep-learning inferencing framework which runs TensorFlow models on MCU powered devices (with Mbed). In comparison to GPUs and mobile CPUs, MCU based devices are much more cost and power efficient. We believe this will open a new paradigm to AI and edge computing.

In practice getting it to work is more complicated, configuration options have to be given and the missing parts of the toolchain need to be provided. In this presentation we will go through the steps needed to use an X86 linux host to cross-compile an application to run on an AArch64 target, using as many of the LLVM tools as possible. We'll cover:- Getting hold of the LLVM tools and libraries.- Providing the missing bits that LLVM doesn't provide.- The configuration options needed to make it work.- Running the application using an emulator.

With Kubernetes – a container orchestration system – updates to a new version of an application can be propagated on the nodes automatically. When the new version has only a few changes compared to the previous versions, this results in downloading the same content again, wasting network bandwidth. With casync – a content-addressable data synchronization tool – we could do better.

IoT.js is a javascript platform that aims to provide inter-operable services for IoT world. Powered by JerryScript, an ultra-lightweight modular JavaScript engine, the platform is designed to bring the success of Node.js to constrained IoT devices. To address interoperability, IoT.js has provided a Node.js friendly architecture and comes with a subset of Node.js APIs. Since Samsung OSG first presented IoT.js in FOSDEM in 2016, the platform has been through a rapid growth in last couple of years. With a lot active high-quality contributions from the IoT.js and JerryScript open source community, IoT.js has released version 1.0 in July 2017 which presented a rich set of features, hardware and tool supports for developers. In this talk, we are looking at recent developments in IoT.js and share our vision for future plans. The talk is supported by a demo of iot.js running on constrained device seamlessly connects to node.js for third party cloud access.

However, the JVM manages moredata than just bytecode, Java objects JITted code. In order to manageheap memory and to ensure correct execution, the JVM and JITted codeneed to retain and, occasionally, interrogate details of the loadedclass base. Bytecode is not a very 'efficient' representation for thispurpose, nor does it include details of runtime-derived info like classand method implementation dependencies, compile history and JITted codestatus, or execution profiles.
So, the JVM throws away most bytecode after parsing, in its placeconstructing and maintaining its own 'efficient' in-memory (C++) datastructures which model both the loaded class and method base andruntime-derived state. This is what is known as Class Metadata. ClassMetadata is a significant component of the Native Memory storageallocated and managed by the JVM, alongside JIT Compiler Metadata, GCMetadata, Thread Metadata, etc. For small applications that don't createa large number of Java objects Metadata can constitute a large portionof a Java application's resident memory set.
This talk will begin by describing how to use the jcmd tool to measuresummary JVM Native Memory storage costs, including overall ClassMetadata costs. It will also show how to use jcmd to obtain a detailedbreakdown of the latter costs, splitting the overheads along two axes:firstly, by class; and secondly, dividing per-class costs into separatesub-costs associated with different component subsets of the classmodel: classes per se, constant pools, methods and annotations.
I will go on to explain how Class Metadata is carved out of the memoryregions managed by the JVM's Native Memory allocation routines anddetail the memory layout of the various C++ types which define theelements of the Class Metadata model, thereby clarifying some of themore detailed statistics available in jcmd output. Real-life use caseswill be employed to explain how specific costs arise from code designchoices and to suggest how alternative choices might increase ordecrease Class Metadata costs.

I'll explain:
Large websites and webapplications commonly provide pages that require loading of Megabytes (sometimes tens of Megabytes) of JavaScript code. That's bad both for the network and for the loading speed of the page. While source code minifiers can help, they make the code harder to read and debug, and sometimes slower to load. The JavaScript Binary AST is an ongoing work to extend the JavaScript Virtual Machines with a novel compression format that should make the code both smaller and faster to parse, without making it hard to read and debug.
We'll present the JavaScript Binary AST, as well as the tradeoffs we need to make between parsing speed and file size to guarantee safety and make it compatible with future versions of JavaScript.

Forget about your textbooks! Existing implementations of shell interpreters contain hand-crafted character-level non-modular syntactic analyzers and yes, their source code are very hard to read.
What if you had to program the parser of a shell script verifier? Would you accept to throw away your favorite lexer and parser generators which had let you write high-level declarative implementations for decades? Would you accept to mix lexing, parsing and evaluation in a single large bowl of spaghetti code? Of course not. You would hardly trust such a parser.
In this talk, we will introduce "Morbig", a modular, high-level and interoperable parser for POSIX shell. The implementation of Morbig relies on key features of Menhir, an LR(1) parser generator for OCaml.

Want to parse a toml file into a static Config struct and report parsing errors as compile-time errors? Well, now you can do all that (pending RFCs for the details). In this talk I will present miri's design, its usage in the compile-time evaluator as well as future features that are enabled by it
The common perception of machine learning is that it starts with data and ends with a model. In real-world production systems, the traditional data science and machine learning workflow of data preparation, feature engineering and model selection, while important, is only one aspect. A critical missing piece is the deployment and management of models, as well as the integration between the model creation and deployment phases.
This is particularly challenging in the case of deploying Apache Spark ML pipelines for low-latency scoring, since the Spark runtime is ill-suited to the needs of real-time predictive applications. In this talk I will introduce the Portable Format for Analytics (PFA) for portable, open and standardized deployment of data science pipelines and analytic applications. I will also introduce and evaluate Aardpfark, a library I have created for exporting Spark ML pipelines to PFA, as well as compare it to other open-source alternatives available in the community.

The Ceph distributed file system (CephFS) has taken aleading role in providing this as a cache-coherent, horizontally scalable, and POSIX-compatible file store for OpenStack operators, leveraging Ceph's dominance and flexibility in OpenStack deployments where it already providesobject and block storage solutions.
The OpenStack Shared File Systems service, Manila, provides a modular framework for securely exporting file shares to tenants in the cloud. In this session we will describe how Manila has been extended to support export of shares backed by CephFS via the NFS protocol to tenant VMs. We’ll discuss reasons for using NFS instead of or in addition to doing native CephFS exports and cover current and planned approaches to such issues as multi-tenancy, performance, and scale out of services.
This talk will be of immediate practical interest to cloud operators who have or are planning use Ceph clusters for object and block storage and want to use the same cluster for shared file services as well as to those more generally interested in Manila, distributed file systems, or Ceph evolution.

A movement towards a unified windowing method and unified decoding methods has started. For Kodi version 18 a Direct Rendering Manager / Kernel Mode Setting (DRM/KMS) windowing method has been implemented. This allows any device that has a Linux kernel DRM driver to run kodi. The next step is video decoding, where each SBC has it's own specific decoder and software to run it. The Linux kernel implements a Video4Linux2 (V4L2) subsystem where drivers can register a decoder to be used under a common API. Kodi needs to be able to use a zero-copy path in order to display these decoded frames on the screen. For this to happen we need to use DRM-PRIME buffer sharing and specific EGL extensions to present the frames. All this together will allow Kodi 18 to run on a vast variety of SBCs that have DRM driver and a V4L2 driver available.

The wonders of just-in-time compilation are available in C++:runtime specialization, code derived from data structures, and many more!Easy::jit provides a simple interface over the LLVM's just-in-time compiler.No specific compiler knowledge is required!
A single function call serves as the specification for the generated code andentry point for the just-in-time compiler.The user can precisely control when the compilation is launched,do it in a separate thread if desired or cache the generated code,and manage the lifetime of the generated code.
int baz(int a, int b) { ... }
int foo(int a) {
// compile a specialized version of baz auto baz_2 = easy::jit(baz, _1, 2); // mimics std::bindreturn baz_2(a); // run !}
The call to easy::jit generates a mix of compiler directives and runtimelibrary calls, that are picked up by an especial LLVM pass.This pass embeds metadata and bitcode versions of the C++ code in theresulting binary.A runtime library parses the metadata and bitcode, and generates assemblycode based on the runtime library calls in the code.
This talk introduces the Easy::jit library, the approach of a compiler-assisted library,its current limitations, and tries to gather feedback from experts and potential users.

Ouroboros simplifies creating networked applications by providing a single abstraction that unifies IPC and networking APIs. Ouroboros provides a powerful networking subsystem that allows building secure overlay networks on top of UDP/IP and Ethernet. To increase scale and scope, overlays can be added on top of previously created overlays. Management of applications running on top of Ouroboros, such as making a server application available on a certain overlay, can be done on-the-fly and with great ease.

By orchestrating your application deployments you gain benefits such as documentation as code, testability, continuous integration, version control, refactoring, automation and autonomy of your deployment routines, server- and application configuration. Ansible uses a language that approaches plain English, uses SSH and has no agents to install on remote systems. It is the simplest way to automate and orchestrate application deployment, configuration management and continuous delivery.
In this talk you will be given an introduction to Ansible and learn how to provision Linux servers with a web-proxy, a database and some other packages. Furthermore we will automate zero downtime deployment of a Java application to a load balanced environment.
We will cover how to provision servers with:* an application user* a PostgreSQL database* nginx with a load balanced reverse proxy* an init script installed as a service* zero downtime deployment of an application that uses the provisioned infrastructure

Due to its many drawbacks and bad design decisions a new user space interface has been implemented in the form of the GPIO character device which is now the preferred method of interaction with GPIOs which can't otherwise be serviced by a kernel driver. The character device brings in many new interesting features such as: polling for line events, finding GPIO chips and lines by name, changing & reading the values of multiple lines with a single ioctl (one context switch) and many more. In this presentation Bartosz will showcase the new features of the GPIO UAPI, discuss the current state of libgpiod (user space tools for using the character device) and tell you why it's beneficial to switch to the new interface.

Embedding dynamic runtimes such as for Lua or Javascript for dynamic scripting within the Rust-App would introduce an huge overhead. A WebAssembly-engine seems to be a good choice as compact and portable runtime environment. JIT-compiler may be used in future to transform WASM files to native code.
The talk will present WebAssembly technology and the benefits and pitfalls integrating it into a Rust-app. Small routines are implemented in C++/Rust and compiled to Wasm. The Rust-App is loading the wasm-code as plugin at runtime to execute dynamic tasks.

They contain executable instructions as well as static, visual data. They are binary files that, even when "open", are often shipped without source code. They are sensitive to namespace collision problems but are only exposed in user interfaces by name. The files themselves are governed by copyright, but the design they encode is not considered copyrightable in the US and other jurisdictions. Furthermore, the typemaking industry has long vacillated on the appropriateness of reviving, reusing, and extending earlier works as new designs. This talk provides an overview of the intellectual-property law and the community norms that concern sharing, reusing, and extending typeface designs. It will help developers navigate the intellectual-property and license-compliance issues they may encounter when using and redistributing free-software and open-source fonts.

Computer Vision (CV) software, in particular the powerful open source OpenCV (http://opencv.org) has made big leaps in power and usability, and is ready to come into its own as a key part of an advanced IoT solution.
At the same time the Go programming language aka Golang has won over fans with clean code, high-performance, and portability. But there has not been any way to unlock the most state-of-the-art CV libraries using the most state-of-the-art programming language... until now.
Introducing GoCV (https://gocv.io) a new package for letting Go programmers create computer vision applications using OpenCV.
In this talk I will show how to use GoCV to build the next generation of computer vision applications, with live code demonstrations.

The successful deployment and data reception of the UPSat satellite, high power amateur rocket launches and realtime telemetry decoding, automatic decoding of LEO satellite signals from our crowd-sourced network of ground stations are some of the milestones achieved. And all these with the help of Software Defined Radios!
In this talk, we present briefly the UPSat and the High Power Rocketry project and then the version 3 of the SatNOGS project. In the new version we have developed several decoders that operate in realtime during a LEO satellite pass. Combined with the SatNOGS rotator that tries to point as accurate as possible to the satellite trajectory, the decoder searches for transmitted frames. The successfully decoded frames are then uploaded automatically on the SatNOGS database for visualization and further analysis.
Currently, SatNOGS project incorporates decoders for many popular in LEO satellite missions transmission schemes such as AFSK1200, APRS1200, (G)FSK9600, APRS9600, APT, DUV, CW, LRPT using the GNU-Radio toolkit. In addition, decoders for APT and LRPT are producing on the fly the weather images transmitted by the corresponding meteorological satellites. For the most interesting of the available decoders, we present the design and the implementation details among with a live decoding demo from a IQ captured observation.
All of the available decoders are running in realtime on the RPi3 platform. To achieve this, several design decisions were made (RF performance vs realtime operation) and we discuss some of them.

Originally focused on voice, aditionnal functionalities were rapidly added like video, instant messaging and presence. From the beginning, Linphone follows IETF's standards, for both media and signaling. On the signaling part, Linphone does implements many SIP based RFC for call establishment, presence and instant Messaging. Today, group chat function is widely available on most popular communication applications, specially in the closed source world. As a free SIP communication application, Linphone aims to provide a free alternative for group communication.
On SIP world, Group chat is handled as a particular case of realtime group communication. The basic RFC is the https://tools.ietf.org/html/rfc4353, Rich Communication Service (RCS) endorses many conferencing RFCs to specify how group functions shall be implemented. For Linphone, we decided to follow the same path, but with always keeping in mind to avoid complex development not bringing essential functionality. Resulting implementation can be defined as an "Adhoc pager mode conferencing" with the idea of Long Term Conference leveraging on SIMPLE IM for message transport instead of MSRP.
This discussion will focus on both interpretation we made of existing SIP standards, implementation challenges and future extensions.

The realtime synchronization happens entirely in the client and the content is encrypted so that the server cannot read it. This lecture will present the encryption and key-management model, the sandboxing architecture which prevents a majority of CryptPad code from accessing the secret keys and some research into a solution to prevent backdoors in the javascript sent from the server. There will also be a discussion of how to reuse the CryptPad architecture (and source code) in developing other security/privacy conscious webapps.

Pairwise-generated test suites cover all combinations of two therefore are much smaller than exhaustive ones yet still very effective in finding defects.
I have taken the pairwise approach and applied it during an entire release cycle of Red Hat Enterprise Linux. I've made an experiment where I have reduced the test matrix for 9 product variants and 4 CPU architectures to a size suitable for execution by a single person. In this talk I will explain:- what is the background of the product and how it was traditionally tested- how I've constructed my experiment- how many test cases I was able to remove from the test matrix- how the results and risk level compare to the standard exhaustive test suite!
I will also talk about bugs found and bugs missed by the two approaches.

The metadata accompanying the RAW data are preserved, and sidecar files, like MD5, LUT or XML, can be added into the Matroska container as attachments. This allows to manage these audio-visual file format in an effective and transparent way (e.g. native playback by VLC), while saving typically between one and two thirds of the needed storage, and speeding up the back-up on LTO cartridges. When needed, the source is retrieved bit-by-bit.

For simple operations the cost of copying the data can quickly dominate, and in complex cases can limit our ability to take advantage of specialty hardware. This talk explores how improved formats are being integrated to reduce these hurdles to co-operation.

Compiler guys love generated code. So in our obfuscating compiler, we have adeclarative format to specify tons of stuff on our passes: its name, it'sapplication level, its documentation, a sample usage, its options (with defaultvalues, help string etc), but also it's priority in the pass pipeline and a fewother stuff specific to a code obfuscator.

Complexity of the translation process originates from the inherent gap between LLVM IR and any mainstream instruction set architecture (ISA). Processors and their ISAs have been designed historically to be programmed by human assembly developers. Recent ISAs gained more complex features based on hardware considerations. To date, ISAs are designed with no respect for the IR of compilers. Hence, translation between IR and MC keeps being a complicated task.What about lifting the target machine to meet LLVM Assembly instead of lowering LLVM IR to meet an unrelated ISA? A lifted target machine can simplify backend development. One may wonder, however, what else can be gained from such an endeavor? The answers to these questions might be relevant for those who are interested in hardware architectures and likewise for those working with compiler and application development.This talk reveals how we realize a processor whose ISA is tailor-made to suit LLVM IR; what we expect from a rich ISA matching LLVM Assembly; and how we plan to utilize this technology to implement a multi-purpose architecture for IoT devices.

A network function (filtering, NAT, encapsulation) is any program that manipulates network traffic. Snabb eases the effort to write such programs. Snabb fits in the category of user-space networking. Snabb by-passes the Linux kernel talking directly to the hardware. This makes Snabb a very convenient tool for high-performance networking. Unlike other user-space toolkits such as DPDK or VPP, Snabb is entirely developed in Lua which significantly lowers the adoption barrier.
In this talk I introduce the Snabb toolkit. Through real-world examples you will learn how Snabb works and even how to start prototyping your own network functions.

During the last years, this feature has beenconstantly improved. In OpenJDK 10 CDS will be extended by AppCDSwhich additionally allows the sharing of application classes betweenVM instances (see JEP 310: Application Class-Data Sharing [1]).
In this talk I will briefly introduce CDS and AppCDS. Afterdemonstrating its various use cases, I will do a short deep-dive intothe implementation details and challenges. Finally I will brieflydescribe how Strings and Symbols can be stored in the CDS archive andshared across VM as well since OpenJDK 9.
After the talk, the audience should have a better understand of theCDS/AppCDS feature and be able to decide whether it makes sense to useit for their own applications.

Writing maintainable and scalable tools is even harder. We'd like to provide instant feedback to the developers and our project presents a working prototype. The uniqueness of such a general framework consists of two rules:
make the analysis incremental: do not run the full check on every commit, but on the changed and affected partswe achieve incremental evaluation based on the ingraph engine
use declarative queries: the common visitor-collector pattern results in bad developer experience, complex plugins/plugin system and huge maintenance overhead as the project growswe use openCypher to query the AST and ASG, this keeps the analysis rules as simple as possible
In this talk we will introduce how the flexibility of the DASH7 Alliance Protocol can be used to solve a lot of IoT use cases. Starting from a simple embedded application which measures sensor values we will demonstrate how the full stack approach of DASH7 enables you to (re-)configure the behavior of the network stack and application, over the air, without touching the application code. Different communication schemes will be discussed together with the trade-offs for aspects like energy consumption and down-link latency. We show how the simple but powerful API (based on file operations) allows to approach a network like a distributed database which you can address based on data queries instead of using node addresses. Finally, we will also discuss the implementation of OSS-7, related tools and the road forward.

But, the availability of a robust update tool solves only one step in the complex chain from a software artifact to an updated and working system on your devices.
Starting with a modern system consisting of a recent bootloader, kernel, init system and update tool, this talk ventures beyond the basic and already solved topics of A/B redundancy, atomicity, or simple update verification.
Enrico will present strategies for creating a robust update chain from automated testing up to full rollout management and show how to solve these challenges with recent Open Source software such as barebox, RAUC, systemd, hawkBit, casync and labgrid. You will learn how to deal with more modular and complex system setups, restricted systems, error recovery, product variants, resigning for deployment, updating the bootloader itself and interaction with verified boot.

Rust is designed for building low-level systems processes that are reliable and safe. Nevertheless, it is still important for developers to ensure their code is doing the right thing. To achieve this, Rust has a rich set of built-in testing tools for writing unit tests.
In this talk we cover general unit testing techniques for Rust. We will also demonstrate how to mock out complex dependencies using the double crate. Examples will range from simple cases to complex cases that you'll often see when testing real world systems.
The talk is suitable for both novice and experienced Rust developers, as well as non-Rust developers who are interested in learning more about the language.

This can be especially tricky for fast-growing projects where there are competing voices, pull-requests, and directions — all growing exponentially.
Docker, Inc. is one such example that created the very popular open-source 'docker engine'. To help meet the needs of both commercial and open-source constituents, Docker announced in April 2017 that the open source work would happen under the banner of the Moby Project.
This talk looks at the the different needs that drive an open source project and a product-based corporation. I'll cover what the Moby Project is and how it relates to Docker's commercial products and I'll highlight some of the experiences we had during and after the transition.

DESCRIPTION:Servers can't be trusted! Whether it's because of a malicious company, a rogue employee, a government agency, a random hacker or malware, your data is not safe if it's just sitting there exposed on a server.
Luckily, there are ways to mitigate some of the threats, for example by making your server more secure, using a server you trust (self-host) and using end-to-end encryption, so the server doesn't have access to this information. While these are great, the server can still successfully manipulate your data, this is where tamper-proof journals come into play and help reducing even that.
In this talk Tom will show some of the threats your data is facing on servers even when self-hosting and using end-to-end encryption, explain what tamper-proof journals are, how they can mitigate these threats, and how they are used by EteSync to better secure your data.

It ranked #1 in popularity in Stack Overflow questions and is consistently featured in the top 10 languages of the TIOBE Index. Originally intended for client-side scripting, the language is now widely used to build complex desktop applications, write server-side code and program IoT devices. The latest standards of the language are released yearly under the ECMAScript trademark and contain sophisticated features and syntactical constructs.
Static analysis is a software testing approach that is performed without compiling and executing the program itself. This allows developers to catch programming errors before building, testing and deploying the code. There is a wide range of static analysis tools: linters and code style analysers repeatedly perform checks in IDEs, while more complex analyzers, such as type checkers, run as part of the continuous integration (CI) process.
As JavaScript is a dynamic language, static analysis approaches are particularly useful: they can detect erroneous type usages that would not be revealed by building the code, but only occur during thorough testing or even worse, at production. Thanks to the popularity of the language, there are already numerous approaches for static analysis available, such as Tern, Facebook’s Flow and TAJS. However, none of these fitted all of our requirements:
As none of the current approaches satisfied these requirements, we built our own solution that uses a property graph query engine to represent the code graphs used for analysis and graph queries to evaluate the analysis rules. Compared to other static analysis frameworks, the novelty of our solution is twofold:
Using declarative queries, our tool is able to perform the complex analysis queries quickly, including:
The analysis can be easily extended by custom analysis rules defined in the openCypher language. Building the system on openCypher also allows us to use different query engines: both mature databases, such as Neo4j, and also experimental engines, such as our own ingraph engine. The latter is our research prototype that supports live query evaluation for Cypher queries, which allows near instant answers even for complex analysis rules.
In this talk, we give an overview of the steps involved in transforming the source code file to a syntax graph and converting it to a call flow graph. We demonstrate how openCypher queries can be used to capture complex analysis rules in a concise way, and how ingraph allows us to continuously evaluate these queries.

LibreOffice on the desktop is very feature packed office suite. One of the complaints that power users make in Online is that it lacks many of them: they cannot add colored borders in their paragraphs, manage tracked changes/comments, correct the spelling and grammar in the document, etc. The question is how do we bring these functionalities to the cloud at your disposal in your browser tab?
We at Collabora decided to come up with a plan to just tunnel all the hard work that developers have done for the past couple of decades: come up with appropriate infrastructure to open the dialog in headless mode, paint it as a bitmap in the backend, and tunnel the image to you in the browser. And then add life to them by tunnelling your mouse/key events back which will invalidate and update the new image you see in the browser. Of course we are not sending the whole dialog image back to your browser every time - only the part that needs updating in the dialog is sent back to the browser saving us precious time and network bandwidth improving your UX.

But how to run automated end-to-end tests against your product when your architecture and deployment processes are complex? How to orchestrate your test environment when your product is a SaaS application but can also be installed on-premises on bare metal or deployed into the cloud on to your Kubernetes cluster?
Using containers to automatically test your application is a great use case, but sometimes running tests only against containers might not be enough.
We decided to create a click-driven, black-box integration testing framework, using Ruby, headless Chrome, Docker and Kubernetes, to test GitLab.
This talk is a story about building this integration testing framework. It is about obstacles we had to overcome, essential complexity that we had to embrace, but also about problems that we still need to solve and our hopes for the future.

After a brief general overview of the Cortex-M0 programming model, exception handling and other basics required,we'll start our deep-dive into one specific implementation in the Chromium-EC firmware.We'll look at startup code, how tasks are implemented, how to deal with priorities and peripheral interrupts.
The Chromium-EC firmware is a little (RT)OS that runs (mostly) on ARM cores of the Cortex-M class (M0/M3/M4),and powers Google's Chromebooks as well as other devices (Project Sulfur SDR). It's permissive license makes it attractive for (ab)use inother projects, since Kernel and U-Boot integration are already existing.

These include cache side-channel exploits against underlying shared resources, which arise as a result of common industry-wide performance optimizations.
More broadly, attacks against hardware are entering a new phase of sophistication that will see more in the months ahead. This talk will describe several of these attacks, how they can be mitigated, and generally what we can do as an industry to bring performance without trading security.

However in most cases we just drop the idea and continue with our life because we know it would take days or weeks to be able to develop that quickly before you could reap the benefits.
What if there was a way to have these apps developed and working in just a few minutes!
We'll demonstrate how a next generation wiki platform allows to do just that by using the XWiki open source project as an example.

Mozilla’s DeepSpeech and Common Voice projects are there to change this.In contrast to classic STT approaches, DeepSpeech features a modern end-to-end deep learning solution. Based on Baidu's Deep Speech research paper, it trains a model by machine learning techniques. This model directly translates raw audio data into text - without any domain specific code in between.To train systems like DeepSpeech, an extremely large amount of voice data is required. Most of the data used by large companies isn’t available to the majority of people. That's why Mozilla launched Common Voice, a project to help make voice recognition open to everyone.

The UEFI way of doing that was to provide special UEFI byte code (EBC). Unfortunately nobody really cared so compiler, firmware support and providers of EBC option roms ceased and basically every UEFI option rom today contains native x86(_64) machine code.
If you now want to plug a PCIe card into your shiny ARM server, that means even though firmware would be compatible it still can't execute the option rom. Until you add QEMU to the mix.
Join me in exploring the depth of UEFI binary interfaces, marshalling between different architecture's function call ABIs on the fly and learn how to integrate all of this into a working firmware, running on real hardware, driving a real PCIe adapter.

However, recently, we have started taking SSSD beyond its bread and butter LDAP client role to provide services that are usable in a broader context, as an application gateway or to a local machine. As a result, you might soon see SSSD enabled and running in your favourite distribution by default or quietly running on the background of another service.
In the talk I will demonstrate what enhancements we already did in SSSD, such as how to use SSSD as a gateway between an application and a user database or why should you let SSSD manage your Kerberos credential caches .
I'll also illustrate things we are working on for the future such how to add and access extra attributes of your local users or why it makes sense to let SSSD handle smart card logins even for local users.
The talk will be useful to system administrators, mainly those who deal with user account management, but also to developers who work on services that integrate with user databases.

In this talk we will walk through a few of these features, and how they can be used from plain old java code. For example we will see how to access local variables from calling methods, as well as powerful ways to monitor what the JVM does when executing our code.
Free Java allows us access to these features, as well as the ability to contribute towards improving their implementation and make them publicly available to other users. Together we can influence the direction of Java and help get more powerful features into the standard JDK.

For this reason, we have recently included Go as one of several candidate programming languages in an evaluation of their suitability for expressing sequencing pipelines. Other programming languages we have evaluated were C++ and Java. Go hits a sweet spot of performing very close to the best results with little programming effort and few compromises in terms of safety and generality.
This talk will present highlights of this experiments and the most important insights.

As common for microkernel-based systems the whole networking infrastructure, down from the drivers up to the socket implementation resides in the userland and comes in cleanly separated building bricks. Today, the framework provides various such building bricks to be combined into an individual solution for each use case. This includes components like an L2/L3-router component with NAT and DHCP functionality, a network-bridge component, a socket-filesystem server using VFS, NIC and Wifi-drivers, as well as libraries like the Lightweight IP and the Linux IP stack. The talk shall give an overview about the design of this ecosystem, how it can be used, how it evolved, and, last but not least, discuss its future.

If this isn't clear, for an example of exactly what the problem is, try an Internet search for "Laptop trackpad supplier". Did you find one? Did you find a source of trackpads for use in that laptop that you're thinking of designing? Or did your search queries instead get completely and utterly swamped with thousands upon thousands of aliexpress pictures of the EXACT SAME Apple Trackpad for a 13in Macbook Pro?
What about LCDs? Do you even know what type of LCD is commonly available right now? Were you aware that MIPI is Cartelled? Or that the people telling you that eDP is "The Future" are trying to push a much higher-power-consumption design at you and they forgot to invite China-based Manufacturers to the closed-door meeting. How can you actually find which LCDs are commonly manufactured and available in Shenzhen, so that you can begin the design right now before you take that expensive trip abroad.
And what about components? If you've looked on taobao or aliexpress, you'll know that many of them are rip-offs, there's absolutely no datasheets, the vendors make pittance so they're extremely unlikely to answer your questions... so what actual use is this resource, to anyone?
This talk will help answer the paradox of bridging the gap between Shenzhen market prices and the Western and Libre mindsets for hardware design, allowing attendees to take proper advantage of the lower pricing of Shenzhen-sourced parts, and to avoid the nightmare scenario of designing a PCB only to find that its parts went End-of-Life in the Shenzhen markets many years ago, and that the last remaining parts available must be bought from Digikey and IMPORTED (back into China from where they originated!) with a whopping lead time and huge import tariffs of up to 40 percent.

If we want to analyze any Open Source development community, it's key to understand the relationships of the people that define that community. Open Source communities provide many ways for peers collaboration beyond participation in forums and mailing lists. In any case, people graph or network analysis is one the methodologies used for social interaction analysis.During this talk, I'll show social network analysis with a free, open source software Kibana plug-in integrated in GrimoireLab. I started this project during my degree thesis, 6 months ago, and once it was released everything has changed. People started to download the plugin and contribute to it. Now, the repository hosting the plugin has more than a hundred thousand clones and a hundred of daily visits.The talk will show how to use the Network plugin in order to analyze open source projects. I'm going to show data retrieved from an open source project and I will show that with differents types of networks/graphs.

Local access to hardware is not always convenient to arrange when multiple members of a team are working on the issue across country and timezone borders. It would also be inefficient to allow much sought after hardware to idle when one team is not actively using it out of office hours for example, as traditionally happens when hardware is shipped. The author, who is currently working as one of the maintainers the Intel graphics i915 Linux kernel driver, has sought for an efficient solution when working as a home based employee for multiple companies. Some off-the-shelf solutions exist, but they're far off in the price range to be suitable for an average Open Source contributor. This talk will walk you through the gotchas in setting up an environment for your project and a demo of one system can be presented optionally.

However, productivity would be very much increased if the writing-correction-publication would be taken a step (or two forward) to a continuous integration/continuous delivery DevOps-like environment where you define by software the whole pipeline a book is going to follow from writing to publication. LitOps is a transpiling of the DevOps culture to book production, using mainly software development tools, and rigging them so that you can produce and publish quality-checked books using as many automation tools as possible.

Furthermore, manual system tests often unveil unexpected faults simply because humans are more sensitive in this regard. Actually, almost every developer does this kind of manual tests "somehow". However, due to the lack of a proper tool support, these tests happen in an unplanned, unsystematic way and without documentation. As a result, it is hard for users to find out which features of a product were tested in which environment, on which hardware, and with which result.
We are working on a novel web application named SystemTestPortal for creating, running and analyzing manual system tests. The tool aims at being useful for developers, testers, test managers, and end-users. It is lightweight, written in Golang, available under the GPLv3 license, and developed in a student project. Many of its planned features are working already and it's getting steadily closer to a mostly complete 1.0 release.
This lightning talk will give a brief introduction and demo how the tool can be used to test a typical free software application.

Although the Chromium browser on Linux still defaults to use the X11 window system, there have been efforts to port it to different environments.
This effort happens in various fronts, including the development and stabilization of Ozone, an abstraction layer for graphics and input events, and the transitioning of some ChromeOS-oriented solutions to Linux, for example Chromium's new "UI service".
Igalia has been actively contributing to this multi organizational collaboration, aiming at getting a full fledged Chromium browser running natively on Wayland. The work happens on Chromium's upstream repository so that the greater Chromium community can benefit from it.
This presentation intends to show the Chromium project's way to Wayland.

Thanks to the rich log entries, new insight can be reached to understand the systems.
In this talk I will talk about structured-logging and show how useful.

In this age of fast storage, inefficiencies in storage software stacks that were previously acceptable with slow spinning devices, are no longer tolerable. There are even faster technologies, like NVDIMMs, on the horizon. These developments are particularly challenging for distributed storage solutions like Gluster and Ceph, where network latencies are a fact of life.This talk is on performance analysis and troubleshooting tools and techniques for this age.

Preexisting and new applications will have to adapt to this new environment that is fundamentally different from how things used to work on X11 for a long time. This talk gives you the basics of programming native Wayland clients in 2018: the Wayland architecture and protocol world including recent developments, what you can and cannot do, the steps to get something visible on the screen, and why you might not want to do a native application after all.

The last three years of them in English to allow exchange students to participate as well. I am using FreeBSD in my class and the lab exercises. Topics of the class include an introduction to the Unix shell, editors, filesystems (with a big focus on ZFS), shell programming, grep/sed/awk and since 2017, I also added Ansible. In this talk, I want to reflect on what I learned interacting with the students of various (Unix) backgrounds. I also want to discuss with the audience how to improve the class with relevant topics so that the students get the most out of the class and for their later Unix careers. I'll provide an insight into my labs and what we do there with FreeBSD, too.

DP is far from being a dumb cable and requires that the entire graphics stack works together to gracefully handle mode failures and recover them. Achieving DP compliance requires that the kernel drivers, hotplug events and the userspace compositors all work together to render every frame at requested rate e.g by handling link failure. The Linux Kernel's atomic modesetting infrastructure on the other hand is a daunting beast of its own and understanding how all the pieces interact is a challenge itself. In this talk Manasi will present the ultimate technical solution for DP compliance ensuring a successful modeset that is recently upstreamed in Linux kernel (4.12) as well as Xserver (1.19.3)
