Software isolation in Linux- as used in the development of openconnect VPN server

For the development of openconnect VPN server a decision to compartmentalize the server was taken, in order to protect any sensitive values exchanged, ranging from the user transferred data, to the data used during the authentication process. This talk will summarize the issues faced during that development that relate to software isolation. That would cover issues with protecting the server's keys via TLS, the client-side authentication of TLS, and PAM authentication, and how they were solved.

Go at CoreOS- This session will discuss using Go to build products that make distributed computing as stress-free as installing a Linux distribution.

At CoreOS, we chose to write everything in Go at a time when Python was the language of choice for Linux distributions. It had been almost 10 years since a new Linux distro was created. With the entrance of the cloud era, moving deeply into distributed computing based on Linux containers and multi-core machines, we needed a language that would allow our developers to iterate rapidly and create self-contained components that were not tangled in a web of software dependencies on the operating system. Go was the clear choice because it would enable us to build applications quickly and produce standalone binaries. With thousands of hours of Go experience, this session will dive into the trenches on Go at CoreOS. It will explore four major projects written in Go: etcd, fleet, rocket and flannel. Attendees will learn tips and tricks for using Go for building and shipping products. Learn the ways Go enables CoreOS to build simple tools to solve a large variety of infrastructure automation tasks, and create high performance components for distributed systems.

QGIS Tool for Landslide Hazard Assessment

In Southern Kyrgyzstan, large areas are affected by high landslide activity, which regularly results in casualties and economic losses. There have been many efforts in the past and the present to analyze landslide activity in this large data-scarce region. Yet there is a need for creating a system capable of integrating all of the existing information and include the possibility for future updates. Due to the limited funds and multiple end users, minimization of costs and flexible accessibility are requirements for such a system opting for the use of open source software. The presented tool has been developed as a QGIS plugin. That way, it is possible to take advantage of the core QGIS functionality and other plugins, e.g. the OpenLayers plugin. The plugin allows the user to access the data on landslides, their triggering and predisposing factors in an easy-to-use way. A typical workflow includes querying landslide and factor data for a certain time period and then assigning them to mapping units for further analysis. Besides data queries, the plugin offers tools for spatial analysis, e.g. finding the highest point of the landslide polygon as an approximation of the landslide main scarp, extension of the standard zonal statistics functionality for the derivation of landslide attributes, pixel- or polygon-based calculation of earthquake influence, etc. PUBLIC CONFIRMED Geospatial https:/fosdem.org/2015/schedule/event/qgis_landslide/ AW1.121 Darya Golovko PUBLISH 2765@FOSDEM15@pentabarf.org

PixelVault- Using GPUs for Securing Cryptographic Operations

Protecting the confidentiality of cryptographic keys in the event of partial or full system compromise is crucial for containing the impact of attacks. The Heartbleed vulnerability of April 2014, which allowed the remote leakage of secret keys from HTTPS web servers, is an indicative example. PixelVault is a system for keeping cryptographic keys and carrying out cryptographic operations exclusively on the GPU, which allows it to protect secret keys from leakage even in the event of full system compromise. This is possible by exposing secret keys only in GPU registers, keeping PixelVault’s critical code in the GPU instruction cache, preventing this way even privileged host code from accessing any sensitive code or data. Due to the non-preemptive execution mode of the GPU, an adversary that has full control of the host cannot tamper with PixelVault’s GPU code, but only terminate it, in which case all sensitive data is lost. We have implemented a PixelVault-enabled version of the OpenSSL library that allows the protection of existing applications with minimal modifications. Based on the results of our evaluation, PixelVault not only provides secure key storage using commodity hardware, but also significantly speeds up the processing throughput of cryptographic operations for server applications.

The development of cache2k has two streams: It is a robust cache implementation and provides features we miss from other products, on the other hand it is a research area to try out new caching algorithms and implementations to achieve the best performing in-memory Java cache that is available today. The talk will start with some real-world scenarios and challenges and how the cache can help, making it the pivotal point in an application to manage data resources and provide them on time. The second part of the talk will be about modern and adaptive caching algorithms and why you should not implement yet another "LRU cache" by yourself. This talk should encourage to use more caching to speed up applications and, of course, to hack and improve existing caching products. There is still much to achieve!

Bridging the gap between simulation and GIS

Polygonal meshes are the most common way of representing 2D geometries for simulation purposes. Integrating simulation to a GIS requires storing georeferenced meshes in a databases (or using standard SIG file formats), and being able to use simulation values interpolated over the elements as a map layer. This presentation reviews what is the closest you can get with existing FOSS GIS solutions and what is needed to bridge the gap, both on the simulation side and on the GIS side. We show the few lines that need to be added to the simulation code to read a mesh from the GIS and write the results to the GIS. We also present a prototype mesh layer for QGIS that has been implemented as a PluginLayer.

Karen Sandler, Executive Director of the Software Freedom Conservancy, will discuss the peculiar tension in the intersection of free and open source software and corporate interest. Working in free software often triggers a complicated set of allegiances. When tricky situations arise how do developers decide what their priorities are? As a community how do you know whether a contributor is advocated the best for the project of the best for their employer? How much can governance help? And at the end of the day, how do the ideological components to these projects really play out? And how should they?

A dedicated kernel named TORO

In systems with high-grade multiprocessing, we have identified two bottlenecks: in the accessing of the memory bus and in the shared resources. To deal with these issues, we propose a dedicated kernel named TORO that is optimized to run a single multi-threading application. TORO is demonstrating an innovative operating system by integrating at the same ring level both kernel and the user application server. In addition, the accessing to resources (e.g., Filesystem, Networking, Memory) is dedicated to specific processor. Then, only the CPU where is dedicated the resource is allowed to access to the instance of the resource. As a result of this design, the kernel provides direct access to all resources without any overhead, and therefore maximizes performance for the overall system. To sum-up the approach, in TORO, the threads of the user application server are distributed evenly on all CPUs and running independently in parallel. The memory model chosen is NUMA without pagination. During the initialization, the memory is divided proportionally for each processor installed on the system. When a thread needs memory, the memory allocator returns a free block of memory depending on which CPU the thread is running. In the same way, TORO can dedicate resources to specific processor, i.e., a FileSystem. This only CPU then can access to this instance of FileSystem. The scheduler is based on the cooperative threading model, therefore due to this design, TORO can migrate threads between CPUs and send messages between threads without using any lock instruction.

Qucs: overview, status and roadmap

This talk presents Qucs (Quite Universal Circuit Simulator) features, the current status of development and the project roadmap. Qucs is an integrated circuit simulator. The graphical user interface (GUI) is used for schematic capture and visualization of simulation results. It can simulate the large-signal, small-signal and noise behavior of the circuit. The software aims to support all kinds of circuit simulation types such as DC, AC, transient, S-parameter, noise analysis, harmonic balance analysis. Digital simulation and circuit optimization are integrated into the GUI and powered by other open-source tools (Icarus-Verilog, freeHDL, ASCO). Besides the library of components it also includes tools for the design of active and passive filters, transmission lines, attenuators and matching circuits. Interfaces for Matlab/Octave and Python are also available. The talk will provide an overview of the features and available tools along with a selection of examples. It will present the latest developments including: migration towards the latest Qt framework; new features related to the “turn-key” Verilog-A (ADMS) model compiler as well as support for other simulation engines (ngspice). The project goals are ambitious. This talk aims at presenting what Qucs can offer as well as tease the audience into thinking what is achievable with the open-source EDA tools available today.

Sustaining the zero assembler port in OpenJDK: An inside perspective of CPU specific issues

OpenJDK comes with a zero assembler port called Zero. Back in 2009 when Zero was originally developed by Gary Benson, OpenJDK was available only on x86, x86_64 and SPARK. Despite recent JIT ports, such as the AArch64 and ppc/aix port, Zero still remains relevant for many Linux distributions. For example, at Red Hat we build and use the OpenJDK zero variant on PPC/PPC64 and s390/s390x. What's more it's a useful tool for getting new JIT ports built from source using free software. This talk will give a brief summary what Zero is and how it works. It will cover some of the recently discovered issues with sustaining the Zero port, how we try to catch them early and it will explain our experience with pushing fixes upstream. There will also be examples how this effort benefits the OpenJDK ecosystem as a whole.

The CHERI CPU- RISC in the age of risk

The CHERI research CPU extends the 64-bit MIPS ISA with byte-granularity memory protection. CHERI enables language memory model enforcement and fault isolation in hardware rather than software. In contrast to past capability models, CHERI complements, rather than replaces, the ubiquitous page-based protection mechanism, providing a migration path towards deconflating data-structure protection and OS memory management. Furthermore, CHERI adheres to a strict RISC philosophy: it maintains a load-store architecture and requires only single-cycle instructions, and supplies protection primitives to the compiler, language runtime, and operating system. This talk will present the CHERI softcore and associated software stack and describe how building on open source has enabled full-stack security research.

Thou shalt not leak your keys- Practical key privilege separation using Caml Crush

The Heartbleed vulnerability made one thing very clear, current TLS stacks lack an efficient way to isolate the cryptographic material from the application layer. Hence, this vulnerability required the massive renewal of private keys and certificates. This sure was a costly and painful process for IT departments. The most efficient approach consists of using Hardware Security Modules or smartcards to store the cryptographic material. Keys remain confidential while being usable through an API to perform cryptographic operations. PKCS#11 is a standardized security API that is widely adopted by device vendors. However, deployment of such hardware can be costly and inconvenient in many scenarios. We propose using Caml Crush, a PKCS#11 filtering proxy, in combination with software PKCS#11 tokens. This architecture leverages process isolation between the TLS stack and the cryptographic material. This low-cost alternative is immediately applicable to PKCS#11 compliant software. We demonstrate that this architecture has a low performance overhead by benchmarking the impact on web hosting scenarios.

Using Firefox to debug web apps on any device- Introducing the Firefox Developer Tools Adapter

Debugging mobile apps in a world of multiple platforms will always be a classic case of "write once, debug everywhere". A monoculture avoids this problem, but brings a boatload of others, so there is really no way around that. Once we come to terms with this fact however, we can start demanding more from the tools that we use to do said debugging. Do we really have to become proficient in a multitude of tools, one for each platform that we intend to deploy on? How often must we context-switch and app-switch in order to get things done? The Firefox Developer Tools Adapter presents a unique approach to the aforementioned problem. In this talk we will dive into the design and implementation of the Adapter, explain why it is a valuable addition to the mobile developer's toolchest and discuss how it can be used to solve real-life problems.

GRASS GIS 7: Efficiently processing big geospatial data

You see beautiful maps every day, you use geospatial data every day but do you know what's behind processing all the big geospatial data? With the advent of open geospatial data in Europe new opportunities arise. In our presentation we show GRASS GIS (Geographic Resources Analysis Support System, http://grass.osgeo.org), a software suite for geospatial data management and analysis, image processing, graphics and map production, spatial modeling, and visualization. The software has been developed as FOSS for more than 30 years by a large community of developers and users. After six years of development and a long beta release cycle the new stable GRASS GIS 7.0 release is imminent. GRASS GIS 7 is rich in functionality, it offers e.g. enhanced vector network analysis, voxel processing, support for massive time series data management, an animation tool for raster and vector map time series, a graphical image classification tool, and a "map swiper" for interactive maps comparison. The software is portable among most operating systems including GNU/Linux, Mac OSX, FreeBSD, AIX, SUN Solaris, other Unix based, and MS-Windows. GRASS GIS 7 offers a new Python API (PyGRASS) for rapid development of workflows. For working teams, it supports shared data management on networks. It can be used as a geoprocessing backend for Web Processing Service (OGC WPS). For statistics, it comes with an interface to R statistics. In our research context, we use GRASS GIS extensively for massive geospatial data analysis on a high-performance computing system (HPC). In our presentation, we illustrate workflows and results using "EuroLST" temperature dataset (http://gis.cri.fmach.it/eurolst/) as an example of data in the multi-terabyte range.

First Steps in Receiving Digital Information with RDS/TMC

The Radio Data System (RDS) is a digital subcarrier on ordinary FM radio broadcasts that is used to convey a bunch of information including station name, time, alternate frequencies, and optionally traffic information with the Traffic Message Channel (TMC) protocol. Given its ubiquity, narrow bandwidth demands, and frequency band, RDS might be a good first digital project for SDR newcomers, extending the 'Hello World' of SDR, i.e., the FM receiver. RDS can be received with very cheap hardware like the RTL-SDR and simple antennas making the technology accessible for everybody. In this talk, I will give a short introduction in RDS / TMC and present the current state of the GNU Radio RDS project. Besides the receiving part, we will also have a brief look in the transmit side that allows you to create your own small radio station including RDS and TMC messages. The information is hopefully just enough to whet your appetite and helps to get you started.

LuaRocks - fostering an ecosystem of Lua modules- Creating the package manager for the Lua language

This talk will present LuaRocks, the package manager for modules for the Lua programming language. Lua has successful as a scripting language embedded into applications, especially in the gaming industry. However, its "no-batteries-included" design prevented it from getting traction as a stand-alone application language. LuaRocks was created to target this problem. This talk will discuss the particular challenges of developing a package manager for Lua. With this project, we've been successfully fostering an ecosystem of extension modules, improving reuse of Lua code.

Common Lisp-Style Macroexpansion applied to C- A Code Generator from Lisp-Syntax to C-Syntax

We describe a new free software project, called CGen [name might change], a C code generator with support for Common Lisp-style macro expansion. It is based on a new S-Expression based Syntax for C (and C-like languages) which is transcompiled to C (or C-like) code. Our code generator supports the simple and efficient management of variants, ad hoc code generation to capture reoccurring patterns, composable abstractions as well as the implementation of embedded domain specific languages by using the Common Lisp macro system. We demonstrate the applicability of our approach by numerous examples from small scale convenience macros over embedded languages to real-world applications in high-performance computing. After successful presentation at ELS in 2014 we decided to polish our research prototype and make it available as free software.

Pseudo GTID and easy replication management

Pseudo GTID and easy replication management This session introduces a technique called “Pseudo GTID” which allows easy refactoring of replication topologies, and makes balanced, deeply nested topologies achievable, safe and productive. Managing large replication topologies introduces difficult questions: do you place all your slaves directly under the master? Do you setup intermediate masters thus creating deep replication trees? How do you synchronize sibling slaves when their master dies? How do you recover replication of a slave if its intermediate master is gone? MySQL’s Global Transaction ID (GTID) comes to solve the above. However GTID comes with its own limitations and not always or not easily applicable. Pseudo GTID is a non intrusive solution that utilizes standard replication, and turns your existing replication topology into a GTID-like topology, allowing you to repoint slaves however you like. We will quickly discuss the problems incurred by standard binary log file & position setup, and the limitations of GTID, Pseudo-GTID injection. We will present the algorithm and implementation for utilizing Pseudo GTID to freely repoint slaves.

From Debian-GIS to OSGeo live and back

Debian GIS is a project with the goal of making Debian the best distribution for Geographical Information System applications. OSGeo live (live.osgeo.org) is a self-contained bootable dvd, usb thumb drive or virtual machine based on Lubuntu, that allows you to try a wide variety of open source geospatial software without installing anything. It also contains a set of uniform documentation (description and quickstarts) to guide people around the different projects. Even though OSGeo live is based on the packages in Debian, both projects diverted and where OSGeo live managed to get a large (100+) community of contributors, progress in Debian GIS was stalling. Recently however, a new wind is blowing in Debian GIS (among others with the Debian pure blends initiative) and many changes from OSGeo live are being incorporated back into Debian. Apart from presenting both projects I will highlight some problems people encounter when they would like to add their package to Debian GIS, and how Debian pure blends try to solve this.

The Tumbleweed Factory- from an unstable development branch to a fully rolling binary distro

openSUSE Factory is the head development branch for the openSUSE distribution releases. As such the explosive mixture of changes and new versions throughout the whole stack from kernel to the desktops made openSUSE Factory a challenging distribution to use even for hard core distribution hackers. To make Factory usable for a wider audience of distribution developers it had to be made more stable while retaining the short turnaround times needed for a bleeding edge distribution. openSUSE therefore introduced a number of automated and semi-automated tools for review and QA into the development workflow to reach that goal. The result is now called openSUSE Tumbleweed, a fully rolling binary distribution based on openSUSE Factory. This talk explains the development process and the tools used to turn openSUSE Factory into Tumbleweed.

Suppose you want to import virtual machines you already have into oVirt to enjoy a features-rich open sourced management system. You will soon figure out that the conversion of virtual machines running on different hypervisors or managed by different management systems into oVirt is not an easy task. The next major version of oVirt is going to introduce an integrated process that will simplify import of virtual machines not being managed by oVirt into oVirt. This session gives a heads up for the feature: we will go over the design and see how it solves issues that we had before to provide better way for import virtual machines to oVirt.

At OpenChange, we work on offering a portable Open Source implementation of Microsoft Exchange Server and Exchange Protocols. During the past 10 years, we have seen the community growing but not the number of developers. The conclusions were clear. The price to pay to develop on OpenChange was too high: C language only, very complex, too much knowledge required, too much time before you get visible results. We have addressed all these obstacles and will teach you during this talk how to set up the development environment in no time, understand the basics of the OpenChange REST API and leverage its resources and samples to get first visible results in Outlook today.

Large-scale graph processing with Apache Flink

Apache Flink is a general-purpose platform for batch and streaming distributed data processing. This talk describes how Flink’s powerful APIs, iterative operators and other unique features make it a competitive alternative for large-scale graph processing as well. We take a close look at how one can elegantly express graph analysis tasks, using common Flink operators and how different graph processing models, like vertex-centric, can be easily mapped to Flink dataflows. Next, we get a sneak preview into Flink's upcoming Graph API, which further simplifies graph application development in Flink. Finally, we show how to perform end-to-end data analysis, mixing common Flink operators and the Graph API, without having to build complex pipelines and combine different systems. We will go through a step-by-step example, demonstrating how to perform loading, transformation, filtering, graph creation and analysis, with a single Flink program.

Open Standards for Big Geo Data

In Geo service terminology, coverages represent spatio-temporally varying phenomena, such as sensor, image, simulation, and statistics data; incidentally, these typically are prime Big Data contributors in practice. The OGC unified coverage model encompasses regular and irregular grids, point clouds, and general meshes. As opposed to the (abstract) coverage model of ISO 19123, the (concrete) OGC coverage and service model establishes verifiable interoperability while still grounding on ISO 19123. The OGC Web Coverage Service (WCS) comprises a modular suite for accessing large coverage assets. WCS Core provides simple data subsetting whereas extensions add optional service facets up to ad-hoc filtering and processing. By separating coverage data and service model, any service - such as WMS, WFS, SOS and WPS - can provide and consume coverages in addition to WCS. Generally, the WCS suite is appreciated by implementers due to its clear structuring and concise conformance testing, down to pixel/voxel level. Many WCS implementations are available today, such as rasdaman which has proven efficient on 130+ TB datacubes. In our talk, we present the OGC coverage data and service model with an emphasis on practical aspects. Presentation will make use of available services allowing participants to recapitulate many of the facets addressed.

Zooming in on the New MySQL Group Replication Plugin

MySQL Group Replication is a recent MySQL plugin that brings together group communication techniques and database replication, providing both a high availability and a multi-master update everywhere replication solution. At its core is a set of group communication primitives that act as the building blocks to create reliable, consistent and dependable messaging between the servers in the group. This allows the set of MySQL servers to coordinate themselves and act as a consistent and replicated state machine - in which transactions commit in the same order on every server. As a consequence, the group itself is fault-tolerant, and so is the service provided by the group - the MySQL database service. In addition to HA, the plugin provides multi-master update everywhere with row-level conflict detection. This builds on the fact that the servers in the group have to agree on how to progress the replicated state machine and so also check for conflicts. Come and learn about the technical details of the exciting and popular MySQL Group Replication plugin and discuss how this fits in the overall picture of MySQL HA solutions.

I'll discuss the strange asymmetry of being an external contributor to a project but not being able to know all of what is going on. I'll try my best to explain the baffling role of Projects and JEPs. I'll speculate about the future of OpenJDK and how it must change as more people outside Oracle contribute significant slabs of code, and how we must have more external patch reviewers.

Profiling PHP applications

It's nothing new that speed is important for the success of any web application. Only a few hundred milliseconds may lie between a user leaving your site or staying. Unfortunately performance problems are oftentimes hard to fix and even harder to pinpoint. In this talk I will show you how we at ResearchGate measure web application performance, which means not only timing how long the PHP backend took to deliver a page, but also tracking the speed the users actually perceives in the browser. After that you will see how you can track down and analyze any problems you found through measuring with the help of tools like Xdebug, XHProf and the Symfony Debug Toolbar. And if you still need to get faster after optimizing and fixing all these issues, I'll introduce you to some tricks, techniques and patterns to even further decrease load times.

Rapid GNU Radio GPU Algorithm Prototyping from Python- with gr-theano, gr-channels, and friends

Theano is an exciting relatively new open source library which was developed by the machine learning community to accelerate the training of Deep Neural networks and other mathematical algorithms built on scipy by generating compiled kernels for the CPU and the GPU using the CUDA compiler and simple python algorithm definitions. Since GNU Radio provides native python blocks which execute work functions directly on scipy-style input and output vectors joining these two technologies is a magical approach which allows for the extremely rapid definition of work block mathematical kernels, and the automated compilation and offload onto massively parallel graphics processing unit hardware. By using this approach we will demonstrate how some highly concurrent and computationally expensive algorithms can be implemented extremely concisely and executed efficiently using graphics processors to accelerate GNU Radio channel models and other blocks with minimal effort. For more information on Theano see: http://www.iro.umontreal.ca/~lisa/pointeurs/theano_scipy2010.pdf and http://arxiv.org/pdf/1211.5590.pdf PUBLIC CONFIRMED Software defined radio https:/fosdem.org/2015/schedule/event/so_sdr_much_dsp/ AW1.125 Tim O’Shea PUBLISH 3081@FOSDEM15@pentabarf.org

JMAP- A better way to email

For the past 4 years, FastMail has been working on a next generation email protocol for our web interface. We have years of experience writing email clients and servers, and we know where the pain points are. This protocol is in production right now, and a 30 second demo will show it in action. At the moment the email world is divided. Every vendor is building their own proprietary JSON protocol, because IMAP+SMTP is a really poor fit for mobile apps and even the LEMONADE protocol changes haven't made the experience good enough. We want to change that by offering a completely unencumbered standard which is good enough that companies don't need to build their own, and gain an interoperability layer which is better for everybody. Raise the baseline experience if you will. We believe it's possible to have a protocol which is both open AND good.

Provision and manage Docker containers with Foreman- Roll out your applications in containers with ease

Deploying containers, images with Docker is becoming a big trend. However, large installations of containerized applications are still few and far between, and solutions are either proprietary or they force you to use their own cloud. We believe Foreman can fill this space by providing a central space to provision and manage your containers and your network, as we already do with your data center. This provides a great framework for mixed environments where physical machines, vms, and containers are all used in conjunction. Orchestration through Kubernetes is being implemented at the moment. Monitoring, deploying, and everything else is possible to do through the web UI or an API, and it's open source, so if you miss any feature, feel free to add it!

Keccak and SHA-3: code and standard updates- From the Keccak Code Package to a wide range of cryptographic applications

In April 2014, the American National Institute of Standards and Technology (NIST) published the draft FIPS 202 standard for the SHA-3 hash functions and the SHAKE extendable-output functions (XOFs), all based on the Keccak sponge function. Since the selection of Keccak as the winner of the SHA-3 cryptographic open competition, NIST announced that they will exploit Keccak's abilities for other purposes than just hashing, including key derivation, pseudo-random bit generation, authentication and (authenticated) encryption. A first part of the talk will be to give a summary of the current developments around Keccak and the FIPS 202 standard. In the meantime, we have gathered the most efficient implementations of Keccak, SHA-3 hash functions and SHAKE XOFs in the Keccak Code Package. These open source implementations are organized in a way that aims satisfying both the developer of optimized code and the cryptographic user. Central to this organization is a specific internal interface that allows interchangeable optimized codes and a user-friendly set of external services. As a second part of the talk, we will briefly present the current status of this development and how the FOSS community can benefit from (and contribute to) this effort. This is a follow-up of the talk "Keccak: more than sha3sum" at FOSDEM 2013.

FOSS CAD for Compact/SPICE Modeling

Compact/SPICE models of circuit elements (passive, active, MEMS, RF) are essential to enable advanced IC design using nanoscaled semiconductor technologies. Compact/SPICE models are also a communication means between the semiconductor foundries and the IC design teams to share and exchange all engineering and design information. To explore all related interactions, we are discussing selected FOSS CAD tools along complete technology/design tool chain from nanascaled technology processes; thru the compact modeling; to advanced IC transistor level design support. New technology and device development will be illustrated by application examples of the FOSS TCAD tools: Cogenda TCAD and DEVSIM. Compact modeling will be highlighted by review topics related to its parameter extraction and standardization of the experimental and measurement data exchange formats. Finally, we will present two FOSS CAD simulation and design tools: ngspice and Qucs. Application and use of these tools for advanced IC design (e.g. analog/RF IC applications) directly depends the quality of the compact models implementations in these tools as well as reliability of extracted models and generated libraries/PDKs. Discussing new model implementation into the FOSS CAD tools (ngspice and Qucs as well as others) we will also address an open question of the compact/SPICE model Verilog-A standardization. We hope that this presentation will be useful to all the researchers and engineers actively involved in the developing compact/SPICE models as well as designing the integrated circuits in particular at the transistor level and then trigger further discussion on the compact/SPICE model Verilog-A standardization and development supporting FOSS CAD tools.

Effective spelling correction with term relation graphs using Lucene FSTs

Our approach for doing spelling correction has deviated considerably from the default approach Lucene is offering. While Lucene's FuzzyQuery uses a compiled Automaton to filter the dictionary rather efficiently, we directly use normal Automatons and intersect that automaton with a separate FST. This proves to be more efficient for our use case, since it saves memory and time to compile the automaton and also part of the time to identify the matching terms in the dictionary. This approach gives us the possibility to store any meta-information with each term, which is used then to pick the top N spellcorrections. We build a term co-occurence graph, where each vertex is a possible spelling correction of a term and each link is the co-occurence in the same document. Each vertex and link get a score based on the meta-information and edit distance. Then we use graph reduction techniques until the graph contains the desired number of spellcorrections.

Better Devops through Thievery- Effective Practices for Infrastructure as Code

The advent of Infrastructure as Code (IaC) has radically changed how IT infrastructure is built and maintained. Instead of building and maintaining servers by hand, tools like Puppet can be used to describe and automatically configure entire data centers. The implication of this is that the workflow of IT operations is starting to resemble the workflow of a traditional software developer. Writing code to make infrastructure changes instead of directly making changes opens up new opportunities for how changes can be made. The software development field has had 30+ years to learn how to effectively develop code, and their hard won wisdom can be ripped off wholesale to make it a breeze to develop IaC. This talk will discuss the following: <ul> <li>Using version control tools to more effectively administer infrastructure</li> <li>Writing and using tests to confidently make changes and get feedback earlier</li> <li>Using continuous integration services to test changes and run deployments</li> </ul> PUBLIC CONFIRMED Configuration management https:/fosdem.org/2015/schedule/event/better_devops/ H.1309 (Van Rijn) Adrien Thebo PUBLISH 3105@FOSDEM15@pentabarf.org

Zero-Overhead Metaprogramming- Using Self-optimizing Interpreters to make Runtime Metaprogramming Fast

Runtime metaprogramming enables many useful applications and is widely used in frameworks, middleware, and domain-specific languages to simplify the task of application developers. However, today’s language implementations rarely optimize even common concepts such as reflective method invocation or dynamic proxies, despite the fact that solutions for efficient implementations have been advocated since decades. In this presentation, we demonstrate how self-optimizing interpreters can be used to implement runtime metaprogramming efficiently. For the implementation, we use SOM Smalltalk, a little Smalltalk implemented in RPython (think PyPy) as well as Truffle (with Graal on top of the JVM). We show that both platforms can remove the runtime overhead of reflection and thus open up new opportunities for metaprogramming in performance critical scenarios.

Manylines- a graph web publication platform with storytelling features

More and more people work with graphs nowadays, but it is not always easy to publish and share the graph interpretation on the web. Manylines is a web tool built at Sciences Po médialab to solve this issue. Some researchers and students use network visualizations to explore their data, but networks are not as clear as maps and sharing one’s interpretation is difficult. Manylines main innovation is to allow the user to explain and share a narrative about his network: an interactive story where each “slide” is a particular zoom, pan and filtering of the network, completed by a title and description, with fluid transitions like in Prezi. Published as an open source prototype with the source code available on GitHub, Manylines is currently built around three screens: - The first screen allows applying the ForceAtlas2 layout to the network, in order to settle the “basemap”: the definitive positions of nodes and edges used to support further interpretations. - The second screen allows zooming and filtering the network to explore the data and “take snapshots” representing different insights. - The third screen allows composing narratives by building a series of snapshots, adding a title and short description for each step. The result is an interactive slideshow widget where the user's exploration of the network is guided step by step, revealing the key interpretation points one by one. Manylines is a single webpage app built for HTML5 browsers. It makes an extensive use of the sigma.js library to deal with networks within the browser and it implements different features inspired from Gephi, the reference desktop graph viz platform. The WebGL visualization (with Canvas fallback) implemented by Sigma.js allows great performance for networks up to 1000 nodes on an average computer. To reach this level of performance, we optimized the javascript version of the ForceAtlas2 algorithm used by sigma.js. We ported it to use web workers and we optimized the Barnes-Hut quadtree approximation in this context by implementing it as an iterative and not recursive process. We made an extensive use of sigma.js' custom renderers and cameras to build dynamic graph thumbnails, snapshots and widgets. The server side stores the networks, snapshots and narrative data in a Couchbase database (which we discovered in FOSDEM 2014) accessed by a Node.js express REST API.

CockroachDB- Towards an Open-Source Spanner

Many NoSQL databases come with a focus on performance, availability and scalability, sacrificing strong consistency guarantees along the way. In effect, this shifts the burden of providing consistency to the application, and often results in complex and error-prone application logic. Just a few years ago, an intense effort by Google resulted in Spanner - a globally distributed, replicated datastore that puts transactions back where they belong: right into the heart of the database. CockroachDB is a grass-roots effort to bring to the table the guarantees of Spanner (and more) in an open source scalable database that is easy to deploy and, despite the name, quite attractive to have around. In the talk, I'll introduce you to the team behind CockroachDB and the current state of the art, briefly discuss consistency & Spanner and then dive into a tour of what's under the hood.

How (not) to create a language specification for Perl 6- Lessons learned

In the process of designing, implementing, and using Perl 6 (or any programming language), people often refer to ""the language specification"" as a commonly understood and perhaps self-evident fixed reference point. For mature languages this can be reasonable, because the people using that language have generally developed a shared understanding of what constitutes the language's specification. But languages are not all specified in the same manner, and in a new or rapidly evolving language it may be unwise to prematurely commit to an inflexible specification. Perl 6 has gone through several imprecise notions of what constitutes its specification, such as design documents like the Synopses, reference implementations of certain features, and the ""official"" test suite. This imprecision sometimes leads to misunderstandings among developers, confusion for newcomers to the language, and difficulty communicating with external audiences. This talk presents a historical perspective on how Perl 6's specification process has evolved over the past decade: identifying things we've done (or are doing) wrong, things we've gotten very right, and ideas of what that process ought to look like going forward.

It has been used in multiple high profile elections in Spain, first in Congreso Transparente in 2013 by a congressman, then by multiple political parties (including leading ones like Podemos) to do internal binding elections, counting more than 400k votes in 2014. This year we moved to work on it full time, and we're expanding world-wide. Our aim: to be the reference secure open source voting project worldwide.

Rocket and the App Container Spec

Rocket is a simple daemon-free tool that enables users to run containerized apps on their systems free of host dependencies. Containers running under rocket execute like regular processes and can be managed using existing process management tools like upstart, systemd, runit, and etc. Rocket is also an implementation of the "App Container Spec" which defines how to define and build containerized applications based on tooling like tar and pgp. And then host these files easily using standard protocols like HTTP. The goal of the spec is to enable independent and creative implementations of container runtimes and build tools. Both of these projects are open source and part of a young growing community. Come learn how they work and how you can get involved.

Enlightenment, a cross-platform window manager and toolkit- Dealing with Enlightenment portability issues in FreeBSD and elsewhere

The EFL is a toolkit for writing cross-platform applications. Enlightenment is a desktop shell built using this toolkit. Both the EFL and Enlightenment are fast and light on resources (which made them the toolkit of choice in places such as the Tizen operating system and embedded environments) while remaining scalable, but their low level approach complicates portability. In this talk I'd like to summarize our past portability issues and tackle current ones, as well as talk about our future direction. The talk will be focused on FreeBSD, using it as an example, but will also cover our general issues and portability to other operating systems including Windows and OS X.

moviCompile: An LLVM based compiler for heterogeneous SIMD code generation

Numerous applications in communication and multimedia domains show significant data-level parallelism (DLP). The amount of DLP varies between applications in the same domain or even within a single application. Most architectures support a single vector-, SIMD-width which may not be optimal. This may cause performance and energy inefficiency. We propose the use of multiple (heterogeneous) vector-widths to better serve applications with varying DLP. The SHAVE (Streaming Hybrid Architecture Vector Engine) VLIW vector processor is an example of such an architecture. SHAVE is a unique VLIW processor that provides hardware support for native 32-bit (short) and 128-bit (long) vector operations. Vector arithmetic unit (VAU) supports 128-bit vector arithmetic of 8/16/32 − bit integer and 16/32 − bit floating point types. Scalar arithmetic unit (SAU) supports 32-bit vector arithmetic of 8/16 − bit integer and 16 − bit floating point types. The moviCompile compiler is an LLVM based commercial compiler targeting code generation for SHAVE processor family. The moviCompile compiler is capable of SIMD code generation for 128-bit (long) and 64-bit vector operations. This work focuses on compiler backend support for 32-bit (short) vector operations. More specifically, this work aims to generate SIMD code for short vector types (e.g. 4 x i8, 2 x i16, 2 x f16) that can be executed on 32-bit SAU next to the 128/64-bit SIMD code. As a result, moviCompile is able to generate heterogeneous assembly code consisting of both short and long vector SIMD operations.

Arithmetic based implementation of a quadrature FM Demodulator- SDR in GnuRadio

One of the key component in many GnuRadio projects is the quadrature frequency demodulator. This functionality allows to calculate the real analog output of a frequency modulated signal from the IQ-signal, which is mainly captured using HF hardware (e.g. dvb-t dongle, USRP, etc.) by a carrier frequency (band pass domain) and transform it to the base band domain. The most known implementations of the FM-demodulator are based on trigonometric functions. These functions require a high computation effort. Some implementation of “tuned” trigonometric function, which were downsized for FM-demodulation reduce the computation effort a little. A new proposal of a so called arithmetic FM-Demodulator allows to avoid completely the usage of any trigonometric function and speed up the computation process in many times. In the presentation I will introduce mathematical background for the arithmetic FM-Demodulator, show the differences and limitations to the current implementation in GnuRadio Version. Further Philipp will present our result, we had achieved in our lab.

Atomic Mode-Setting- What it is and how to convert your driver

Atomic mode-setting has been discussed and designed for literally years. Now it's finally there. Most of the prerequisites have been merged into the mainline kernel. The first drivers are being converted and the final versions of the user-space IOCTL are being drafted. With it come all sorts of new, exciting features. But there are also confusing aspects to it. This talk will give a brief history of how kernel mode-setting (KMS) evolved, explain some of the shortcomings of the current KMS API and how atomic mode-setting will make everything better. The focus of the talk will be on how to convert existing kernel drivers to support atomic mode-setting based on lessons learned from going through the conversion of the Tegra DRM driver.

The fact that Ruby has different implementations is strange but also powerful as it allows us to write extensions. Although writing an extension can be a daunting task, there's no better way to get to the heart of what exactly Ruby objects are and the reason for some of the language's quirks. In this talk, we'll use an example of writing a C extension for Ruby to use a third-party C security library. We'll peel back the layers of Ruby objects to deepen our knowledge of MRI and to understand in a little more detail what it really means to write object-oriented code.

In our interconnected world of mobile and cloud computing, particularly with the rise of governmental spying, corporate espionage, and theft of data by organized crime syndicates, security is more important than ever. Many claims are being made about the security of open-source cloud technologies: How can administrators, users, and developers separate fact from fiction? This talk will equip the audience with the principles needed to evaluate security claims. We will talk the nature of risk, of vulnerabilities and exploits; the various factors that reduce the risk of vulnerabilities in software; and about TCB, threat models, and defense-in-depth. And we will introduce a colorful and (hopefully) helpful analogy to help make these concepts more clear. We will then apply these principles to three open-source cloud technologies: containers, KVM, and Xen, to see how they stack up. These will be backed up with numbers: lines of code, security advisories, entry points, and so on.

Improving Key Signing Parties- Tools to make them easier, more secure, and much faster

KSP Tools is a set of tools to simplify and automate the tasks that are needed to attend a key signing party. They will significantly reduce the amount of work needed, and reduce the amount of errors that can be made. My aim is to reduce the amount of work to be done before and after the meeting to just 5 minutes, even with the large amount of people that attend the event at FOSDEM (~100 people), without compromising security. I also hope to considerably shorten the amount of time that a key signing party takes through future work. The current tools are: <ul> <li>ksp-makelist: Generates a better formatted key list for usage at a key signing party. It's better looking, more readable, more comfortable to use and can be processed automatically by scanning QR codes.</li> <li>ksp-scanlist: Makes a list of keys to sign by scanning QR codes from the above list.</li> <li>ksp-list: Performs operations on a list of selected keys like signing keys and mailing them.</li> <li>ksp-import-keys: Connects to a mail server and automatically imports signatures people emailed to you.</li> </ul> The tools automatically check fingerprints and use a file format that is easy to handle with standard tools like grep and awk. These tools were made after my experience with key signing parties at FOSDEM and I hope other people will find them useful.

Building an open Internet of Things with Java and Eclipse IoT

Java is a platform of choice for many IoT applications, from building smart gateways that bridge sensors to the cloud, to device management infrastructures or home automation systems. This session provides you with concrete examples of how to build end-to-end solutions with the Eclipse IoT Java stack and in particular how to use open-source projects such as Paho, Kura, Californium and Concierge on top of OpenJDK. You should join this session if you have Java developments skills that you'd like to put to good use for your next IoT project, and if you are interested in learning more about how to use open standards like CoAP, MQTT, 6LoWPAN, … in your Java applications.

Interfacing infrastructure as code with non-expert users

Implementing a tool to automate IT infrastructure management has many undeniable benefits. But that doesn't mean there aren't some drawbacks too (usually outweighed by the benefits) that we should be considering, and working to reduce or remove. Implementing a tool like this in a team usually has a pretty significant impact: new processes, new language(s) to learn, new way of doing pretty much everything on your infrastructure. These tools are complex, so a minority of the team tends to become experts in it, and tries to lead the others. Resistance to change is common and understandable, but unfortunately, this can end up with some of the team members being left behind by the sudden and massive changes to their work. This is clearly not a Good Thing, and certainly not showing very good inclusiveness towards everyone. It is also making some configuration management projects fail, which is definitely a Bad Thing for those of us trying to implement them. How to improve this situation is a topic dear to me. This has always been the focus of the Rudder and ncf open source projects I work on - making our technologies more accessible, easier to adopt and simpler to understand. Some key points we have focused on include: - Avoiding the necessity to write code (user interfaces of course, but that can be combined with other users writing code) - Separating roles so that experts can implement the how and others can focus on the what - Minimising the amount of effort required (sane and non-surprising default values, auto-configuration where possible, ...) This talk will explain some of these concepts, and show how we have achieved considerable success using the ""ncf builder"" web interface that can be used to write configuration management policy without writing any code (see http://www.ncf.io).

Shenandoah - Project overview

Garbage Collection pauses make it hard for Java applications to meet quality of service guarantees. No matter how fast your application processes requests, a 30 second GC pause is going to ruin any guarantees you might want to make. Shenandoah is a new GC algorithm designed to address this issue. We take a simple approach that allows us to do more work while your Java program is running so we can substantially reduce the time the JVM is paused. Our goal is to be able to garbage collect 100gb+ heaps in under 10ms. This talk will focus on the current status of the project, the goals we've met so far, and what we are hoping to achieve in the coming year. We might even share some performance numbers.

Viterbi's little Helper- Coprocessor strategies for Forward Error Correction

Forward Error Correction (FEC) is a vital part of every communication scheme. Convolutional Error Codes can provide the protection of the data to drive the communication system close to the Shannon Limit. But due to the complexity of the decoders, it is challenging to implement these algorithms in software for use in software defined radios (SDR). Available coprocessors, such as graphic processor units (GPU) and single instruction multiple data architectures (SIMD) can dramatically enhance the throughput of such software based receivers. Strategies to start implementing Viterbi- and Maximum A Posteriori (MAP) Decoders on these coprocessors are presented in this talk. Potential tripping hazards are identified. The effects on the throughput of these algorithms are analyzed and shown.

It’s not a bug, it’s an environment problem. Environments are costly and data refreshes tedious. As a result, QA analysts have to make compromises and work in environments that have a different makeup than the production environment, which can create false positives and missed bugs. This presentation will help QA engineers learn how to mitigate the lack of data refreshes by creating modular test cases and use parameters to dissociate the data from the test cases and automation and therefore be able to work with data that you do have in each environment. Additionally, it will dive into how to maximize the environments QA professionals currently have and align them to their testing process to do feature testing and regression efficiently.

At the heart is libhybris - talked about at FOSDEM; found inside the Ubuntu Touch distro, invented and developed at Mer & Jolla where it's used in the Jolla phone (ARM) and soon the Jolla tablet (x86).

picoTCP for Linux Kernel tinification- Replacing the kernel's stack with picoTCP

By replacing the Linux Kernel's TCP/IP stack with picoTCP, we aim to lower the threshold to use Linux on small embedded systems and bring it to the IoT world. In this case we ran it on a Cortex-M microcontroller with a few MBs of RAM and flash. Using picoTCP inside the kernel results in a reduction of the kernel's size by over 300 kb, while still having all of the TCP/IP functionality an embedded system might need, and more. The talk will start with a demo, then a motivition why we did this, and finally explaining how we did this.

Replication is used everywhere with MySQL. But applying writes in a single thread is often a bottleneck: replicas have a hard time keeping up with the master that can execute writes in parallel. Enter MySQL 5.6 and you can use several threads to apply writes on replicas as long as you have several schemas. MySQL 5.7 goes even further: by introducing a logical clock and by changing the scheduling logic, you can apply writes in parallel in a single schema. Come to this session to learn all you need to be comfortable with multi-threaded replication.

Caciocavallo, or how we ported OpenJDK from embedded to cloud and still liked it

Caciocavallo has been one of the very first external projects to land in the OpenJDK repository and sponsored by the OpenJDK Porters Group. Named after a delicious cheese we're never tired of eating, it had the original purpose of refactoring the AWT peers to allow different implementations to be added to OpenJDK. The project evolved very quickly until it became itself a full implementation of AWT based on Swing with just enough abstraction to allow custom plugging into the Java2D system for rendering. As time passed, this characteristic was used to implement a GUI testing framework running on offscreen buffers to avoid the usual problems of focus stealing and random mouse moving that plague every other GUI testing framework (here everything is emulated!), and finally a full Web based backend to allow application to run remotely but still be visible on the local screen. This talk will cover the progress we have done over the years, we will show how easy is to implement a new backend and how this project could be used to give Wayland support to OpenJDK. We will show the testing framework and finally we will discuss about WebJDK, an idea to give more web oriented functionality to OpenJDK and use the web backend to enable fully cloud based applications.

We live in an age in which every person owns two or three devices that are powerful enough to render a few seconds of 3D movies in a while although they are used mainly to send messages via WhatsApp and create selfies for social network consumption. At the same time, all these devices have the closest thing to an universal virtual machine that has ever existed: the JavaScript virtual machined, paired to a (roughly) standard object model that allows anybody with a bit of programming prowess to create programs that can be run anywhere and everywhere. There is great potential for massive distributed computing in this environment, but the ability to tap it a bit farther than sending basic computations is not there yet. In this presentation we will talk about the issues involved in doing so, from basic algorithmic issues to twisted legal issues that can arise when you are using devices you don't own to perform unwitting computations.

Go and the modern enterprise

Successful, tech-related, consumer-oriented companies with "hockey stick" growth -- companies like Twitter, Netflix, Spotify, and SoundCloud -- represent what might be called the "modern enterprise". These organizations run microservice architectures which are continuously built and deployed, deeply instrumented, data-driven, and can fundamentally change from day to day. The open-source software stacks they use gain recognition, contributors, and momentum. Go has many advantages in this kind of environment, and seems well-posed for becoming its de facto language. But we're definitely not there yet. This talk is an experience report of Go in the "modern enterprise" of SoundCloud, and my opinion of what needs to happen with the language and ecosystem for it to gain real mindshare in that environment.

Synthesizing gateware with GCC- Bambu: A Free Framework for the  High-Level Synthesis of Complex Applications

Programmable devices such as FPGAs can potentially offer very significant computational power, but implementing efficient solutions on them can be a hard task. One of the main obstacles is the usage of hardware description language (HDL), whose knowledge is usually a rare expertise. To overcome or at least to mitigate this issue, High Level Synthesis (HLS) has been introduced: a (semi)-automatic design flow, potentially composed of several methodologies, that starting from a high level representation of the specification to be implemented (e.g., from its C/C++ source code implementation) produces its hardware implementation. This talk presents Bambu a free HLS tools based on GCC developed at Politecnico di Milano, that generated synthesizable HDL description starting from ANSI specifications.

The New MySQL Replication Features in MySQL 5.7 and Beyond

MySQL replication is the foundation for both scalability and high availability for many of the world’s busiest services, in particular, those that operate at scale on the Web. In fact, some of the largest and highest profile online applications trust their data to MySQL and regard MySQL Replication as the key technology to ensure that data is always available, even in the event of catastrophic disasters. MySQL Replication strives to keep on meeting the ever tougher requirements of online services so that it can be deployed together with them in symbiotic harmony. In fact, in recent years we have seen an exponential development in MySQL, in particular in replication. MySQL 5.6 was a major step forward, with fabulous replication features, but the work continues and MySQL 5.7 is set to be another ground breaking release. The next generation of replication features are scattered over several technical areas, including: better semi-synchronous replication; enhanced multi-threaded slave performance; improved monitoring; online configuration changes; options for fine tuning the replication stream performance; support for more advanced topologies; developer friendly frameworks and much more. This is just the tip of the iceberg. In fact, in the lab we have more exciting news such as the MySQL Group Replication plugin, a plugin that brings group communication techniques and database replication together. Seize the opportunity to learn about the new MySQL Replication features' internals, the technical details and the roadmap. Come and learn what is already there in MySQL 5.7 and what's still in the making.

Packed Objects, Object Layout & Value Types - a Survey

Java is often criticized for its lack of supporting C-style structs. This makes it hard to efficiently implement certain type of data structures (like for example arrays of small objects) in Java. However, recently there have been several different approaches which try to address this problem. My talk will briefly introduce "Packed Objects", an extension available in IBM's Java SDK 8, "Object Layout", a layout-optimized Java data structure package proposed by Azul Systems and Value Types [3][4], an OpenJDK proposal for immutable, reference-free value objects. I will describe the commonalities and differences of the three approaches and explain how they can improve the memory overhead and locality of Java objects.

There will be a logo generator that Mozilla is currently working on where contributors can select the data feeds and colors and it will output SVG versions of the logo for use. People will be able to customize the look based on the options they choose. Effectively, the openness and community contribution that is at the core of Mozilla's software projects will be transferred also to its branding, enhancing community identification on that additional level. I will first of all introduce the project and will show images to illustrate the ongoing creative development process led by Sean Martell. Moving on to the protection angle: I will speak about traditional patterns of trademark protection and enforcement and how these are being challenged by the market and marketing realities of our modern times. I will speak about the advantages and appeal of living, or fluid, brands, giving examples (such as Google doodle, MTV, Absolut Vodka, to name but a few). I will point out risks and provide guidance on how a living brand can bridge the divide between valuable community contribution and identification and the restrictions of trademark protection. Essentially, a living brand can have a steady distinctive core which suffices to maintain trademark protection, while certain of its characteristics may be subject to change, community contribution and innovation. The key challenge is to define the core that is to be the subject of trademark protection, without unduly restricting the process of innovation that makes the brand a living brand.

To The Moon And Back. Software Defined Radio and High Power transmissions.- How to do cool things and stay legal.

Today, GNURadio enthusiasts are in the same situation as radio electronics enthusiasts about 90 years ago: Many ideas sound very promising, but international regulations and national laws prohibit extended experimenting. Radio Amateurs such as Nobel Price winner Joe Taylor (K1JT) have demonstrated that digital signal processing allows moonbounce transmissions also to the private hacker, but also many more thrilling experiments such as airplane scatter and the active use of Amateur Radio satellites. Most, however, require a little more power than those 10 dBm produced by the USRP series. This talk shows how easy it is to make use of the definitions of international Amateur Radio regulations as part of the ITU ruleset and how to get a license according to national laws - and to experiment with GNURadio -and- with high power.

CIRELA (Communication and Information technology for REsiLience to disAsters) is a non profit NGO aiming at providing open source solutions to manage, monitor and prevent natural and environmental disasters. Currently we are focusing on wireless sensor network (WSN) based monitoring and warning systems. We are working on WSN applications where people in a disaster-prone area can actively participate, to have access to information, to be warned on time, and to have their own sensor if they want. Jakarta with frequent flood events is currently a case we are working on. A 'simple' WSN based flood monitoring application will measure water levels on different locations using sensors, put this information on a server and make it available to users, warn people when the water level in an area is higher than an acceptable limit, ... So we have to manage a geographically distributed and concurrent system where sensor modules represent concurrent processes. We want to have a pleasant and user friendly environment for end-users as well as for programmers. We started to develop our applications with Pharo. We'll show Pharo with OpenStreetMap and Roassal2: - to visualize geographic data and information - to present and to simulate wireless sensor networks PUBLIC CONFIRMED Smalltalk https:/fosdem.org/2015/schedule/event/cirela/ H.2214 Onil Goubier PUBLISH 2923@FOSDEM15@pentabarf.org

Contract-based Programming - A Route to Finding Bugs Earlier

Contract-based programming is a software development technique, which is used to find programming errors earlier in the development process. "Contract" refers to formal declarations of how types and subprograms ("functions and methods" if you aren't an Ada programmer already) behave. In the strictest form, the contracts are checked as a part of the compilation process, and only a program which can be proven to conform with the contracts will compile. In a less strict form, it is more similar to "preventive debugging", where the contracts are inserted as run-time checks, which makes it more likely to identify errors during testing. Ada provides a quite extensive support for contract-based programming. The checks are specified as a mix of compile-time checks, obligatory run-time checks, and optional run-time checks. In addition to that, SPARK defines a subset of Ada with full compile-time checks.

Supporting Nouveau on the Tegra K1 System-on-chip- How NVIDIA became a Nouveau contributor

Although Tegra K1 uses the same Kepler architecture as NVIDIA desktop cards that Nouveau already supports, there are other challenges that need to be addressed before Nouveau can drive K1's graphic acceleration: the fact that the GPU does not reside on the PCI bus requires architectural changes in the Nouveau core. The absence of dedicated GPU memory directly interferes with the way Nouveau is used to do memory management and leads to potentially sub-optimal behavior. Also, in a system where all devices share the same system memory, PRIME support is mandatory to perform any useful work and the relevance of a driver-agnostic memory allocator becomes perceptible. This talk will discuss these challenges, and in particular the consequences of using a unified memory architecture, in the hope of triggering discussions that will help improving the general support of GPU architectures for new mobile platforms.

Technical Aspects of Leap Second Propagation and Evaluation

Leap seconds are scheduled by the International Earth Rotation Service (IERS) whenever the difference between true earth rotation and the UTC time scale reaches a certain limit. Whenever a leap second has been scheduled by the IERS, a warning must be disseminated to time keeping devices so that clocks become aware of the scheduled leap second early enough to be able to handle the leap second properly. There are different ways to propagate leap second warnings using different timing signals, protocols, etc. For example, the GPS satellites transmit a specific point in time when a leap second is to be inserted or deleted, but other timing signals may just provide a leap second warning flag which is set during a certain interval before the leap event, where the warning interval depends on the specification of the protocol. Also, there are different implementations how leap seconds are handled, which especially affect the sequence of timestamps across the leap second event. The clock can be stepped at the beginning or end of the leap second, can be slowed down or even stopped during a leap second insertion, or time can be slewed across a leap second. This makes it difficult to compare time stamps which have been taken on different systems during a leap second. Last, but not least, there are implementations of time keeping code which don't always work correctly, e.g. invalid leap second warnings are generated, leap seconds are not handled at all, or severe bugs occur due to side effects of the leap second handling.

The challenges of open mobile design- productivity vs content consumption & vision vs design by commitee

Designing in the open has inherent difficulties as the danger of producing a camel always lurks. At the same time the status quo in mobile UI is consumption-oriented. These are the big challenges we face when working on Glacier UI for nemomobile and I believe they are worth talking about. This talk starts with a brief introduction on ways to handle the risk of losing the vision and coherence of the design while still fostering participation, and how we are trying to do that on the nemomobile project. Being friendly and accepting proposals and at the same time keeping a grip on the focus of the design, in a project that lives exclusively on contributors' free time: compromises, solutions and ideals. A quick overview of the tools and workflow follows, and the rest of the presentation delves into the specifics of mobile OS interface design and how we try to evolve a mobile UI that enables productivity on a small screen as opposed to mere content consumption, with Glacier UI.

Use DPDK and the Linux Kernel- Open and High Performance Network Function Virtualization Infrastructure (NFVI)

The SDN Community is building network automation along with OpenStack Neutron's capabilities. This creates connectivity based on Linux kernel functions, prevents single vendor solution lock-in and avoids building proprietary data paths. With DPDK and packet processing software to create NFVI, it is possible to keep this openness while both introducing performance and avoiding Neutron plugins for proprietary technologies. In this presentation, Vincent will show how DPDK applications can be combined on the host and guest of the network, and compute nodes of OpenStack scenarios, in order to sustain high performance for north-south and east-west traffic that is required for NFV solutions. 100 Gbps of packet processing throughput examples will be demonstrated. Down the road, this openness shall apply on any packet processing data plane logic: on x86 hypervisors, ARM CPUs, new IBM Power8 or PCI SmartNICs (Cavium, Broadcom, Tilera).

Our reference implementations are provided by the pure-Java Bouncy Castle cryptography APIs. Our contenders are an assortment of widely-used Java and cross-platform C code: the SunJCE security provider optimized by Java Runtime Environment (JRE) 8, the Mozilla Network Security Services (NSS) libraries employed through the SunPKCS11 security provider and the OpenSSL Crypto library accessed with the help of the Java Native Interface (JNI). We're going to pit software against hardware in our examination how we can leverage the Advanced Encryption Standard New Instructions (AES-NI).

What Could Microkernels Learn from Monolithic Kernels (and Vice Versa)

Some developers of both microkernel and monolithic operating systems view the design of their system as absolutely superior to the other design. This black-white thinking and "holy war" attitude, while understandable to a certain degree, makes it hard to to acknowledge that one size does not necessarily fit all. Rather than striving for an unreachable goal of creating the best operating system design for all possible use cases it is vital to understand and reflect the trade-offs of the use cases at hand. This talk focuses on a few features and properties of the current monolithic operating systems that could be an inspiration for the current microkernel operating systems and vice versa. The talk should also initiate a discussion about some "non-goals" of microkernel operating systems that are nevertheless sometimes presented as goals of microkernel operating systems, to the detriment of its own cause.

We have all got used to memory being essentially infinite, however the IoT reopens the constrained device with devices having 256M or less. This project looks at developing an ARM microJIT targeted at these devices. The project is based on the original work I did on the Thumb2 JIT (FOSDEM 2010). The project targets the Raspberry PI which is an ideal IoT development/demonstration platform. Unfortunately the Thumb2 JIT does not support the Raspberry PI because the Raspberry PI does not have the Thumb2 instruction set. This is a project which I am working on in my 'free' time and I hope to have a demonstrable port by FOSDEM. Finally I would like to have a discussion about the future of this work.

MCUIO/LININOIO - Virtualizing MCU peripherals

MCUIO/LININOIO - Virtualizing MCU peripherals The MCUIO/LININOIO subsystem allows a Microprocessor Unit (MPU), somehow connected to a Microcontroller Unit (MCU), to see the MCU's peripherals as standard Linux peripherals (i.e. gpios, i2c adapters, pwms, ...). The basic communication protocol is completely generic, it just defines ways to read/write a (virtualized) memory space on the MCU. Standard, vendor independent memory maps are then defined for each kind of MCU peripheral, so that MCU specific implementation details can be ignored by the MPU. Interrupt events can be spontaneously sent by the MCU to the MPU as write requests. The protocol is transport independent, only a bidirectional channel is required (for instance rs232 or even a network connection).

CockroachDB- towards an Open-Source Spanner

<h2>CockroachDB a distributed database written in Go.</h2> Many NoSQL databases come with a focus on performance, availability and scalability, sacrificing strong consistency guarantees along the way. In effect, this shifts the burden of providing consistency to the application, and often results in complex and error-prone application logic. Just a few years ago, an intense effort by Google resulted in Spanner - a globally distributed, replicated datastore that puts transactions back where they belong: right into the heart of the database. CockroachDB is a grass-roots effort to bring to the table the guarantees of Spanner (and more) in an open source scalable database that is easy to deploy and, despite the name, quite attractive to have around.

We won't shy away from technical depth where it's needed to uncover all the details, but Truffle is designed to be a high-level and simple system accessible to non-experts.

Ol3-Cesium : 3D for OpenLayers map- An exciting library for automatically bringing 3D to your map

Ol3-Cesium is an exciting web library bringing 3D to an OpenLayers3 map. A Cesium virtual globe is automatically created from the map and displayed side-by-side for collaborative interaction or stacked for exclusive tasks. The globe camera and the map view (centre, resolution, rotation) are bidirectionally synchronized: interacting on one updating the other. Layers are synchronized from the map: - ol3 raster layers show up on the globe and reuse cache when possible; - ol3 vector layers render using the same style and may be positioned freely in 3D. Additionally, specific data may be displayed on the globe, like terrain or vectors. Vectors are re-projected on-the-fly during synchronisation. Since one synchronizer may not fit all needs, the library exports core functions to allow advanced or custom use.

In the beginning, there were bugs. In order to find them faster, before a JDK release, the OpenJDK Adoption Group began a quality outreach effort. Initially focused on JDK 8, the effort expanded to cover JDK 7 Updates, JDK 8 Updates and JDK 9 OpenJDK Projects. It now lists dozens of open source projects and communities that participate in testing early access builds of the JDK, report issues they find, and help get them resolved in time. In this session, you'll learn what worked, and what didn't, and what you can do to join the OpenJDK crowd testing fun with your own open source project to help us find showstopper bugs before they can bite.

It provides detailed, call-stack level, information on where time / energy is spent and memory allocations happen using a variety of techniques varying from dynamic instrumentation to sampled profiling. While not dissimilar from other similar softwares like Google perftools it was specially tailored to profile extremely large C++ applications comprising millions lines of codes, loading thousands of dynamic libraries and with a very high memory allocation frequency. In addition, ease-of-use and the ability to easily share performance profiles between distributed collaborators are important aspects to enable use by a large community of scientists with varying software development skills.

Xen Orchestra: a web UI for Xen and XenServer- Handle modern IaaS needs from the web

XenServer exposes a fully featured management API called XAPI. Xen Orchestra was originally designed as web interface for Xen in 2009, and is now a complete re-write to leverage all those new possibilities. This is the story of a tool evolving from "simple hypervisor management" to a "Infrastructure as a Service" interface, with all the challenges involved. First, we will examine architecture choices of Xen Orchestra (to reduce connections, bandwidth waste, storing of structured data, allowing persistence and so on...), then and how we decide to address common problems, like user permissions and ACLs in a virtualized infrastructure.

This presentation will introduce HAKA's capabilities and show some examples of data manipulation both at the packet and at the stream level. An example of packet dissector and grammar implementation will also be shown to demonstrate how protocol management is handled in Haka more information at http://www.haka-security.org/ PUBLIC CONFIRMED Network management and SDN https:/fosdem.org/2015/schedule/event/haka/ UD2.218A Jérémy Rosen PUBLISH 2755@FOSDEM15@pentabarf.org

Overpass API- A service to query OpenStreetMap data

Using OpenStreetMap data almost always requires filtering for thematic extracts. Overpass API is a web service for this purpose, available at overpass-api.de. Its source code is licensed under AGPL. The open data project OpenStreetMap aims at creating a geographic database of the entire world, i.e. collecting the data necessary to make any map of what is on the ground. Starting in 2004, it has now grown to more than a million registered mappers. In most places details are mapped including each footpath. In some places even streetlamps, trees, wastebaskets, and similar things are mapped. Overpass API allows you to extract data by geographic search criteria, by subject, by structual properties or an arbitrary combination of them. In this way you can realize an always up-to-date data overlay on a slippy map, a desktop data browser, conveniently pull data from OpenStreetMap into QGIS, do quality assurance or a lot of other things. In this talk I will present Overpass API by the above mentioned example use cases. Furthermore, I will give a short overview over the components and the query language. This gives you a starting point to integrate OpenStreetMap data into your application of choice.

Requirements Bazaar- How to encourage users to tell us what they really need!

In this Lightning Talk we want to present “Requirements Bazaar 2.0” that aims to be a social continuous innovation platform to bring developers and end-users together. In years of research we have developed and actually operated an open innovation platform for gathering requirements for prototypes in large international academic projects. The last version of the current product is available under http://requirements-bazaar.org . End-users can enter their requirements by providing short descriptions including user stories, screenshots and other images. The requirements can then be shared amongst its users. On the other side of the chain, developers may take up ideas and transfer the accepted requirements to an issue system like JIRA. Over the last years it turned out that people want more lightweight and mobile-friendly tools; we found the old monolithic system to be very hard to maintain to add new features. Therefore we are currently redeveloping it from scratch integrating many ideas from our users and incorporating new research findings. We are further driven by a mobile-first approach to support a wide variety of devices. We additionally want to support various social features like sharing on social networks or blogs and allowing discussions and rating amongst end-users and developers. At FOSDEM we would like to encourage open source developers in rethinking the way requirements are currently gathered from the crowd. How do we want to collect new software ideas or simply feature requests from our users. Will it really be through feedback forms in our apps’ “About” menu? Do our users really think in terms of issues like we developers do? How can gamification be used to reward actual end-users of software? We hope Requirements Bazaar can answer these questions and fill the gap!

Now that it is being adopted more and more, many strange and wonderful documents will be created by custom software that claim to be ODF documents. The ODF softwares of the world should be prepared. That's why ODFAutoTests helps you to create outlandish documents and lets you run them through your software. This talk will include an enticing argument for writing tests and will present the audience with the data of running the current tests on the current software.

When performance matters ...

Python applications sometimes need all the performance they can get. Think of e.g. web, REST or RPC servers. There are several ways to address this: scale up by using more processes, use Cython, use PyPy, rewrite parts in C, etc. However, there are also quite a few things that can be done directly in Python. This talk goes through a number of examples and show cases how sticking to a few idioms can easily enhance the performance of your existing application without having to revert to more complex optimization strategies.

This is a lot of potential fun, but the entrance barrier for newcomers is extremely high, and it's easy to get lost and not enjoy the fun anymore. In order to help people wanting to contribute keep track of this intricate forest of development and find their way out, the Adoption Group was created (http://openjdk.java.net/groups/adoption/). This session is an exchange between few of the hackers directly involved with the Adoption Group and the public. We will indeed discuss some of the projects we are currently involved with - like the planned global hack days for jsonp, jigsaw and tools that use jigsaw and http 2.0 with language interoperability - but above all we will answer questions the audience may have in relation to getting involved with OpenJDK, both from a technical perspective and a social one, so that next year you can sit together with us helping even more people to jump on the fun!

The Enlightenment project started over 15 years ago, and while it has evolved a lot over the years, its object system has not; this is quite surprising given that almost everything in Enlightenment is represented by objects. Tom, later joined by other Enlightenment developers, has taken upon himself to redesign it, and called the new system Eo. In this talk Tom will describe the main goals they had for Eo, what (and how) they have achieved, how it was received by fellow developers and how it impacted the Enlightenment project as a whole. Tom will also briefly review other C object systems, some of Eo's unique features, and several related projects that were either created to support Eo, had undergone major improvements enabled by it, or owe they existence to Eo.

Every pixel hurts- A quest for open UX design

Design is still a pretty closed process, so I started exploring ways of opening the design process, just as the coding process has been fully opened through collaboration tools, community building, pair acceptance and sharing knowledge. The design community does not have a strong collaboration history. But, since the appearance of the latest UX practices, there is an opportunity to fully open up the process, as UX is based on research and more graphic designers are moving into the UX field. We already know there is a lack of UX practice in FOSS projects, so this talk is a further exploration on why such a gap exists, and a collection of ideas and tools that could (hopefully) empower both sides to put a bridge over it.

VXVDE does not require any program to dispatch packets: vxvde has been implemented as a module of the libvdeplug library. It does not need any infrustructure other than a well configured IPv4 or IPv6 network supporting IP multicast. VXVDE has a very simple configuration. A valid IP multicast address is enough to configure a "switchless switched" virtual network. Unlike VXLAN, VXVDE does not require any Virtual Tunnel End Point (VTEP). Virtual Machines manage their own access to the virtual network. VXVDE unicast packets are mapped on UDP packets traveling on a direct path from the sending virtual machine to the receiving one, without any copy, any packet retransmission or extra header.

Free and open-source software for medical imaging- Bringing technological independence to hospitals

The amount of medical images that are generated, analyzed and exchanged by hospitals is dramatically increasing. Medical imaging is indeed the first step to the treatment of more and more illnesses, such as cancers or cardiovascular diseases. In turn, the data management of clinical images and the administration of the computer network of a medical imaging department imply continuously growing technological challenges. Tasks such as autorouting between imaging modalities, exchanging data between clinical departments or hospitals, or anonymizing images are still hard to achieve in practice. This is a direct consequence of the lack of interoperability software that could bring technological independence to hospitals by creating low-cost gateways between proprietary ecosystems. In this talk, I will explain the pains behind modern medical imaging, from the perspective of the hospitals. The DICOM standard will be introduced, together with free and open-source software supporting this standard. I will then put emphasis on the free software Orthanc, a lightweight, versatile DICOM server. Thanks to its REST API and to its Lua scripting engine, Orthanc is primarily conceived as a central, robust building block to bring technological independence to clinical departments by automating their very specific imaging flows. Orthanc was nominated at the Zénobe Award 2013 for social innovation.

Smart VM scheduling in oVirt cluster- Deep dive to scheduling service based on probabilistic methods

The oVirt project allows efficient management of virtualized datacenters. Deciding what machine should host a certain VM is one of the important functions of the management platform. Unfortunately it is also one of the complex ones, because there can be many rules governing the placement policy and there is a time limit in which a VM has to be started or migration initiated. Till now each VM was considered separately and that caused fragmentation of free resources. We are about to present a new solution to this issue in this presentation. We have started a cooperation with the OptaPlanner team that develops an optimization engine based on probabilistic (soft computing) algorithms. This means that oVirt will feed situation updates to an optimization service and continuously receive improved solutions back. It will then use the precomputed results for rebalancing the clusters.

We have designed and implemented an Intent Fuzzing Framework for Android. Intents are one of the most important ways used by applications to communicate. They benefit also for a very high level of trust inside the Android OS, so if they are not validated appropriate, they might create an unwanted damage, or might even compromise a mobile device, from Security perspective. As a term, fuzzing implies manipulating input data, in order to validate it through the mechanism or device under test. It is usually a black-box, negative testing technique, but we have used it as a grey-box method, also. Knowing how Intents are built, and which type of parameters they accept and expect, we have been able to craft fuzzed Intents, in order to find Security vulnerabilities in the Inter Process Communication protocol.

Copyleft in Europe: How does copyleft interact with Exhaustion Of Rights- To what extent can a copyright owner control copyleft code once it's placed in circulation in the EEA?

Copyleft licences work by conditioning distribution of a work's binary on providing access to relevant source code. Under the European Computer Programs directive, once a copy of a computer program has been placed in circulation in the EEA by or with the consent of the copyright holder, the copyright holder can no longer control circulation ("exhaustion of rights"). Is the condition to provide source an attempt to control circulation, and is the exhaustion principle problematic for the GPL and other copyleft licences? Commentators have suggested that this is fatal to copyleft, but we argue these analyses are overblown.

Tempus: a framework for multimodal trip planning

Open source engines for trip planning are growing in popularity. We are part of the movement by creating our own engine and a framework for the development of new algorithms. Tempus focuses on planning trips that involve all possible transport modalities, mixing private and public modes as well as shared vehicles, and on requests with multiple objectives. It relies on well-known open source components and standards like PostGIS, QGIS, WPS, boost graph and offers tools for importing routing data from various sources, including OpenStreetMap. This presentation will illustrate the overall modular architecture of Tempus built around a C++ core and give some insights on how to use it either as a user or as a developer of planning algorithms.

Multithreading Made Easy, part 3 - Bounded Work Queues

Ada is one of very few programming languages that support multithreading as part of the language, as opposed to libraries. In the previous two episodes, we showed how Ada makes it easy to turn a single-threaded program into a multi-threaded program. We ended up with ten thousand threads working concurrently then introduced a task pool and work queue wherein a small number of threads (one per processor core) process thousands of small work units. But the work queue could become very big. In this third and last episode, we show how to restrict the size of the work queue to a fixed limit, thereby preventing denial-of-service attacks. This presentation will feature live editing of source code, compilation and debugging. Questions from beginners are encouraged. It is not necessary to have attended the first installments. The sources of our example program will be provided to those who want to tinker with them.

In contrast, superoptimization can produce perfect code - the fastest, the smallest or the most energy efficient code. The technique, first introduced in the late 80s found in some cases it could do 25% better than the best assembly programmer, and 40% better than the best compiler at the time. Free software has always played a central role in superoptimization research, with the GNU Superoptimizer being one of the very first tools constructed. However there is a downside. Superoptimization today is incredibly demanding of compute time, so currently it is limited to short instruction sequences. At present it is most valuable in optimizing code hotspots and key library routines, and can also be a valuable aid to the compiler writer for peephole optimization. Recent research has developed new techniques that can make superoptimization more applicable to general code. In this talk I will introduce superoptimization and give some examples of the weird and wonderfully short sequences of code it produces. I will introduce the GNU superoptimizer and show how it is used, including some of the recent improvements I have contributed. The final part of my talk will look at the latest research including machine learning and constraint solving, and show how in future superoptimizers may be able to optimize much larger programs.

XMPP and Android- Creating stable, reliable, push-enabled and battery friendly XMPP connections on Android

Using XMPP on resource constraint systems, like Android devices that are surrounded by a hostile mobile environment, imposes many challenges. But with the right measures a stable, reliable, push-enabled and battery friendly connection can be achieved. This talk will present the required techniques using Smack, an open source XMPP client library written in Java. One outstanding property of Smack is that it's a multi-runtime library, i.e. it is able to run on Java SE runtimes and on Android.

NTF's General Timestamp API and Library- Current timestamps suck. We can do much better.

A good timestamp can be a very useful thing. Unfortunately, most current timestamps don't have enough information in them to be very useful, and they don't "age well"' and are too often not useful outside of the context of where they were taken. After decades of casual thought, Harlan started to document what information would be needed to have a useful timestamp, and what sort of underlying support would be necessary to produce and use them. This turned in to a GSoC project in 2013 where a proof-of-concept user-level library was produced, and some work was done to implement the new timestamp format as a core kernel timekeeping structure in a Linux kernel.

The power of cross-correlating: from GPS reception to passive RADAR using SDR

CDMA systems rely on encoding data streams radiated by multiple emitters on the same carrier frequency with (ideally) orthogonal codes. Recovering the signal from each emitter requires identifying the code assiociated with each source, which hence also requires recovering the carrier to account for relative emitter/receiver motion (Doppler shift), thermal drift and oscillator bias. We demonstrate this concept with the reception of GPS signal -- a constellation of satellites orbiting 20000 km over the surface of the earth -- with 20 euro worth of equipment centered on a DVB-T receiver designed for receiving neighbouring television signals. We extend the concept to passive radar, in which a radiofrequency emitter (television, broadcast radio) signal reflected on a mobile target is used for identifying the velocity and position of the target. In this approach, no active source is needed: RADAR measurement is only a matter of correlating the direct and reflected signal, after identifying the Doppler induced frequency shift.

Perl's Syntactic Legacy- Using the future to improve the past

The Perl programming language is currently enjoying a resurgence in popularity, and for good reason! Perl 5 development continues to move forward with new features being introduced and many old ones improved, meanwhile the development of Perl 6 is making significant progress and has reached a major milestone, the details of which will be announced by Larry Wall at this very conference. For many years now the development of these sister languages have affected and influenced one another in a myriad of ways. Over the last few years I have been working on a design proposal for enhancing and extending the object system of Perl 5 which borrows a number of elements from the Perl 6 object system. In this talk we will explore the various evolutionary stages of that work, as well as discuss the complexities of adding new features to such a mature and well established language like Perl 5. Along the way we will also examine the various meanings of "legacy" in each context and show how it informed the design decisions that were made.

CANCELLED - hardware switches - the opensource approach

Imagine buying off the shelf switch hardware, install Fedora (or any other distribution) and configure it using standard linux tools. This is not possible at the moment primarily because of lack of unified and consistent platforms and driver interfaces. We are working to change that. The current state of support for switch chips in Linux is not good. Each vendor provides userspace binary sdk blob that only works with their chips. Each of this blobs has proprietary APIs. To get switch chips properly supported there's need to introduce a new infrastructure directly into Linux kernel and to work with vendors to adopt it. This talk presents the current effort to unify and uphold the Linux networking model across the spectrum of devices which is necessary to make Linux the cornerstone of industrial grade networking. The scope of this talk covers state of art with current implementation of standard commodity switches such as top of rack switches, small home gateway device as well as SR-IOV NIC embedded switches. A device model and driver infrastructure will be presented for accelerating the Linux bridge, Linux router, accelerated host virtual switches and flow level offloads when supported by the hardware underneath.

CentOS Virt SIG- Community virtualization packages on an immutable core

CentOS is a "distribution" with a rather unique description: it is a free (gratis) clone of a commercially-supported "distribution" with all the branding removed. Being enterprise-grade distribution means solid and well-tested; but it also means not having the latest functionality. It also means having a small enough feature set to provide commercial support in a viable manner: and that typically means choosing one technology and sticking with it. But what if you wanted your entire system to be solid, and well-tested, but want the latest features for one particular package or program? Or what if you really wanted an enterprise system, but wanted to use one of the alternate technoligies that were not selected? This is where CentOS SIGs come in. The new CentOS is still at its core a clone of an upstream enterprise distribution. But having had success with the Xen4CentOS project, which provided a version of Xen to run on CentOS 6, they have now generalized the process. This talk will talk about CentOS SIGs: the vision, the structure, what SIGs are available. We will compare and contrast them to other community distro development models like Fedora, OpenSuSE, Debian, Ubuntu, and so forth. We will also share lessons from the CentOS Virt SIG, in which a number of virtualisation and related technologies such as Xen, oVirt, Docker and others collaborate.

Open source home automation- by OpenMotics

There are 3 problems with close source home automations systems. i. These systems tend to be ridiculously expensive for the features that they offer, since most vendors target the high-end market segment with customized solutions. ii. Configuring and maintaining the system has to be done by a certified installer, giving the customer little control over their own house. iii. Theses systems use closed-source communication protocols and you -as a user- are not able to interface with the system or change anything in the system. OpenMotics is an open source home automation hardware and software system that offers features like switching lights and outputs, multi-zone heating and cooling, power measurements, and automated actions. The system encompases both open source software and hardware. For interoperability with other systems, the OpenMotics Gateway provides an API through which various actions can be executed. The project was open sourced 2 years ago and was started about 10 years. The choice to open source the project was very conscious: we want to offer a system where users are in full control over their home automation system.

Enabling video preservation through open source

Determining what codecs, containers, and specifications should be favored in audiovisual preservation and how to use them is an ongoing dialogue within archives. Media preservation is a relatively small community and thus often relies on technology and recommendations from larger related communities such as broadcast, media production, and increasingly open source development to support the objectives of audiovisual preservation. As the machinery and skills needed to sustain access to film and analog video collections decay it is increasingly urgent for archives to address blocking technological issues in order to re-format legacy audiovisual recordings to digital formats efficiently. This presentation reviews the requirements and demands on technology within audiovisual preservation projects and assesses the opportunities for existing open source technology to contribute to resolving preservation challenges. The presentation will focus on lossless audiovisual codecs, technical and contextual metadata, and both the openness and standardization of relevant file formats.

This creates an Open Source project. There are several instances of this now: OpenStack, Mozilla, Wikimedia, and Jenkins all have open sourced their infrastructure. It is, however, relatively easy to say "our configuration is totally open source, anyone can use it", and it is actually much harder to actively consume someone else's configuration.

Cairo is a 2D graphics library with support for multiple output devices. It is designed to produce consistent output on all output media while taking advantage of display hardware acceleration when available. The Cairo API provides operations similar to the drawing operators of PostScript and PDF. Operations in Cairo including stroking and filling cubic Bézier splines, transforming and compositing translucent images, and antialiased text rendering.

Java restart with WebFX

The purpose of the WebFX project is to investigate the capabilities of using JavaFX to build rich web applications. Actually, it is an attempt to create a new web where HTML is replaced with FXML — the markup language for JavaFX UI, and the logic can be written in any programming language that is available on top of Java platform from JavaScript, Groovy, JRuby to Java, Kotlin and Scala. Java ReStart is a complimentary project that acts as transport layer for WebFX allowing FXML pages to reference arbitrary Java byte code on a web server and hence any custom JavaFX UI components and Java third-party libraries. In addition, Java ReStart allows to run arbitrary Java applications instantly from a web server downloading only required parts of applications on demand and executing them in parallel with downloading. I would like to give an overview of the projects, make a live demo, compare the proposed technologies with traditional web and native clients, show how the technologies differ from Java applets and Java Webstart, reveal benefits in compare with RDP-like approaches. Finally, I will share my vision on how to evolve the projects.

Living on Mars: A Beginner's Guide- Can we Open Source a society?

Humans will go to Mars one day. But what if we skipped the plant-a-flag stage, and instead built a permanent human settlement on Mars in 2025? What challenges will need to be overcome to make this a reality, and how can they be dealt with? What technologies will be needed for a small community to survive (and ultimately thrive) on the red planet? How might the early Martian pioneers engineer unique solutions as they construct the first society on another world? Though it may sound like science fiction, the scale of the challenge ahead is such that an Open Source strategy could prove vital to its success. In a first for human spaceflight, the Mars One project intends to send 4 people on a one-way mission of permanent settlement to Mars in 2025. This will be preceded by a series of unmanned precursor missions, the first one of which is planned for a 2018 departure. What makes Mars One unique is that it is entirely privately funded, international, and apolitical, which enabled it to launch a global astronaut selection process in 2013 - to which over 200,000 people from over 140 countries applied. After a series of cuts, there are now just 660 people remaining in Mars One's selection process. Over the course of 2015, 24 will be chosen to enter full time astronaut training for the mission. In this talk, one of those remaining 660 Astronaut Candidates will explore the architecture of Mars One's mission. A special focus will be on how a one-way trip using just existing technology is not only possible, but is substantially simpler and cheaper than previously proposed return missions.

Our question was: "what is the best infrastructure to run our SaaS on?". We tried most of the infrastructure software, starting from vmware, moving to Proxmox, OpenNebula, OpenStack, and Google's Ganeti. We also considered software storage and software defined networks. We mastered some of these technologies and we even contributed to the projects. But we felt we needed something different and lighter and we "blended" our own solution, mixing and matching the best of the above and keeping in consideration our needs in terms of computing, network and storage.

How to test OpenGL drivers using Free Software

OpenGL is an API for rendering 2D and 3D graphics now managed by the non-profit technology consortium Khronos Group. Implementors are free to provide their own implementation of the API. For example, in GNU/Linux systems NVIDIA provides its own proprietary version while other manufacturers like Intel are using Mesa, the most popular open source OpenGL implementation. Because of this implementation freedom, ensuring compliance with the specification is important. Khronos provides their own OpenGL conformance test suite but there are several unofficial open source alternatives. This talk will explain some of these open source OpenGL conformance test suites and give an introduction about how to use them, including sharing tips between the speaker and the audience.

Domain Specific Languages, defined broadly, are everywhere. We will look at the good, the bad and the ugly and see where Lisp excels (ranting a bit about Configuration Management tools as that's what I spend lots of my day doing) The world is buzzing with the idea of teaching everyone to program. Sometimes we create simpler languages and environments for learning but if we constrain them too much we can impoverish the learner. For scientists we have R, Maple, Mathematica and Matlab etc - but how easy is it to build a web service, run Hadoop jobs, read files in some obscure format or talk to a datastore? Better to give them a productive environment to solve their problems quickly, with the full power of Clojure when they need. Concretely we will reimagine Netlogo and Geomlab as Clojure DSLs. See how embedding them in Clojure makes the implementation easier, gives greater power to the user and enables extension. We have a bunch of great embeddings already in Clojure: logic, stats, datalog, CSP - Let’s build more and not trap people in DSL Hell.

Most of us already owe Prolog a debt indirectly via Erlang. However, logic programming in and of itself has much to teach us about approaches to systems - taking declarative system descriptions to a new level of abstraction, and finding ways to integrate these ideas back into more common workflows. From Prolog to Erlang to Haskell to Lisp to TLC and then back to Prolog I have journeyed, and I'd like to share some of the beautiful and brilliant things I've discovered along the way and why I think they might make us better operations geeks.

Fork and Ignore: Fighting a GPL Violation By Coding Instead- The Story of Kallithea

Typically, GPL enforcement activity involves copyright infringement actions which compel license violators to correct errors in their GPL compliance,thus yielding the policy goals of the GPL: the rights of developers and users to copy, share, modify and redistribute. While traditional enforcement is often undeniably necessary for embedded electronics products, novel approaches to GPL violations are often possible and even recommended for more traditional software distributions. Recently, Conservancy engaged in an enforcement action whereby,rather than fight the violator in court, Conservancy instead fostered and provide resources and assistance to a vetted GPL-compliant fork of a violating codebase. This talk discusses which scenarios make this remedy optimal and lessons learned. The talk includes some licensing and technical content about vetting licensing information of codebases.

Managing Networks in a Software-Defined Future- How OpenNMS is coping, and: is SNMP finally dead?

Since the late 1980s, the discipline of network management has kept up well enough with virtual notions in networks while continuing to rely heavily on the Simple Network Management Protocol (SNMP). The rise of software-defined networks poses similar challenges to the ones brought to the systems management space by server virtualization and cloud computing, leaving practitioners to wonder how much retooling will be needed to cope in this new world. As the oldest enterprise-grade, open-source network management platform, OpenNMS has proved fairly adaptable so far.

We've been talking about Infrastructure providers for quite a bit already. OpenStack itself started as such an IaaS and then it quickly became a cloud provider. But what does that mean? What is a cloud provider suppose to provide? What's cloud after all? Scaling a distributed system goes beyond virtualization, shared storage etc. In order to support on-demand scaling it is necessary to have an easy way to provision and consume the available infrastructure, a way for the services running in it to communicate, etc. Not to mention latency needs, reliability, etc. This talk aims to answer the above questions and take a step further down the path of explaining what should be considered essential for nowadays needs, especially when those needs require a <code>cloud</code> to be covered.

Adapting Apache OpenOffice for adoption in a public administration: configuration, Sharepoint webdav integration and an extension to help users exchange ODF files

This talk aims to give an overview of the introduction of the ODF standard and Apache OpenOffice in an Italian public administration with more than 3000 users, addressing briefly the main technical issues and solutions. In particular we will talk about: 1) the configuration of OpenOffice, extended with community developed and custom extensions to help users in the everyday work 2) the interoperability with Sharepoint through the webdav protocol and what we developed in Apache OpenOffice for the correct interaction 3) our extension to simplify picking the right format for file exchange, to answer the users' ubiquitous question "Ok but… should I use ODF to send/share this?”, in relation to our ODF census project in Italy.

Rizzly: Event Driven Microcontroller Programming- A new programming language for event driven programming of 8 bit microcontroller.

I present Rizzly, a programming language and compiler I am working on. It is designed for the event driven programming of the smallest 8 bit micro controllers. In this talk I first present the concepts and some interesting details of Rizzly. Although one can already use Rizzly, there are several open tasks. In the second part I will address those and present ideas how to solve those.

Crazyflie Nano Quadcopter- A flying open source PCB

In 2009 three Swedish engineers invented a small quadcopter that started with a simple idea: get an electronic board (PCB) to fly. They created the "Crazyflie Nano Quadcopter" which weighs only 19g and fits in the palm of your hand. It can be controlled from various devices, including PC, Android or iOS devices, Raspberry Pi or a R/C remote. While the main client has been written in Python, it has also been ported to Java, C, JavaScript. Since the beginning of 2013 the hardware can be bought from http://www.seeedstudio.com, but the schematics for the PCB and the firmware/host source code are also available on their website/Github account. Due to the low cost for the hardware and the open source approach, the Crazyflie has been used in different private and academic science and research projects around the world.

Open Heart Surgery: HotSpot Debugging at the OS Level

Debugging Java applications is comfortable and simple, but if you want to look beyond the Java horizon, you need special knowledge and and different tools. This interactive session shows you how to debug a running VM or analyze a VM core file with a native debugger like gdb. You will also learn how to use some of the more than 1,200 VM options to trace or modify the VM behavior. This knowledge can greatly help you identify, isolate and reproduce the root cause of hard VM crashes, and it can also be pure fun to see which actual machine instruction the CPU is executing for your Java code.

Perl 6: beyond dynamic vs. static

Is Perl 6 dynamic? Well, it sure looks like it: you can eval code at runtime, do all kinds of late-bound lookups, write code without a type declaration in sight, dynamically generate types, and even mutate the language and the way its object model works. But hang on a moment! Misspell a variable or object attribute? That's a compile time error. Call a subroutine that doesn't exist? Yup, same deal. Passing just one argument to a sub that needs two? There's a good chance you'll be told about that too...at compile time. Want to write code that uses native integers and floating point numbers? Go right ahead and throw in some types. Oh, and those super-dynamic modules that extend the language? They can get in on the act, and flag up things to the programmer at compile time too! In this session, we'll explore how Perl 6 strikes a balance between static and dynamic, how the Rakudo Perl 6 compiler takes advantage of this careful design work, and how the language and implementation are flexible enough to let the programmer pick their own trade-offs if the defaults don't fit their problem.

Termination provisions are a standard component of license agreements. FOSS licenses and FRAND commitments, however, are not standard agreements, as they are founded on ideals of non-discrimination. Termination clauses, which permit licensors to cancel rights of specific licensees, contradict these ideals. The talk will clarify the contradictions between these principles and license termination provisions, explain why termination provisions are nonetheless justified in these models, and illustrate these explanations by reference to a number of current debates.

Pretty-printing kernel data structures- Reusing D-Trace technology in unexpected places

Compact C Type Format (CTF) is a technology created during development of the D-Trace software to describe the C data types. With its second version it evolved into a fully expressive, yet space-wise efficient format that can be used outside of the D-Trace suite too. Compiling the FreeBSD kernel with the CDDL/CTF option triggers the creation of such CTF data that corresponds to the respective kernel objects. This dataset can be parsed and processed to become a source of information needed to pretty print all kernel data structures inside the on-line kernel debugger DDB.
