Free and Opensource Software Developers European Meeting ULB (Campus Solbosch) Brussels 2009-02-07 2009-02-08 2 08:00 00:15 10:00 00:30 Janson welcome Keynotes Podium English FOSDEM Opening Talk The FOSDEM Opening Talk, including the infamous FOSDEM dance. FOSDEM Staff 10:30 01:00 Janson future Keynotes Podium English Freedom, openness and participation have become a pervasive part of digital life. 250 million people use Firefox. Wikipedia reaches people in 260 languages. Whole countries have Linux in their schools. Flickr hosts millions of openly licenses photos. Apache underpins the Internet. We have moved mountains. At the same time, the terrain has shifted. Our digital world has moved into the cloud. And, our window into this world is just as often unhackable phones in our pocket as it is flexible computers on our desktop. Hundreds of millions of people take being digital for granted, and rarely stop to think what it means. The world where free and open source software were born is not the same as the world they have helped to build. It's time to ask: what do freedom, openness and participation look like 10 years from now? How do we promote these values into the future? Building the open web and hackability into the world of mobile is part of the answer. Promoting privacy, portability and user control in the cloud are also critical. But what else? Mark Surman will reflect on these questions and chat with the FOSDEM crowd. Mark Surman 11:30 01:00 Janson debian Keynotes Podium English Observations about the role that Debian plays in the world of Free Software, and some lessons learned that may help other Free Software projects. Bdale Garbee 14:00 01:00 Janson opensuse Distributions Podium English Since this is a distro talk, I will be covering the openSUSE Distro, the openSUSE Build Service, and how to become involved in the project and/or use the openSUSE Build Service to create packages for open source projects for multiple distributions. Joe Brockmeier 15:00 01:00 Janson fedora Distributions Podium English The talk will take a look at the current roadmap for the Fedora Project, from a technical and community-building point of view. The discussion will focus on the recently-released Fedora 10 as well as the in-development Fedora 11, as well as other Fedora projects such as infrastructure, websites, translation, etc. Max Spevack Official website 16:00 01:00 Janson Distributions Podium English This talk will focus on 10 important features that makes it easier for users and developers alike to work with Exherbo. While the talk will focus on the current state of Exherbo and the short-term future the ideas being presented should be equally interesting for other distribution developers and users. Bryan Østergaard Official website 14:00 01:00 Chavanne openamq Development and Languages Podium English I'll speak about a new messaging protocol called AMQP, and the iMatix projects that implement this protocol. AMQP makes it possible to make cheap, fast distributed applications, for pubsub, cloud computing, telecoms, etc.. I'll explain our OpenAMQ implementation of AMQP, and also our web-based RESTful messaging project, Zyre, which makes AMQP work over plain HTTP. This talk is aimed at FOSS developers with interest in new protocols. AMQP is a good example of how large businesses are promoting and investing in FOSS today. Pieter Hintjens 15:00 01:00 Chavanne reverse_engineering Development and Languages Podium English This talk is about reverse engineering a proprietary network protocol, and then creating my own implementation. The talk will cover the tools used to take binary data apart, capture the data, and techniques I use for decoding unknown formats. The protocol covered is the RTMP protocol used by Adobe flash, and this new implementation is part of the Gnash project. Rob Savoye Gnash Official Website 16:00 01:00 Chavanne scala Development and Languages Podium English In this talk I'll describe the design principles of the Scala programming language, which has scalability as its primary design objective. Today's software landscape resembles increasingly a tower of Babel: Systems are built using many different languages, combining server-side and client-side languages, scripting and systems programming languages, general and domain specific languages, all glued together with a hefty amount of XML. The advantage of this approach is that each individual language can be tailored to a specific application domain. Its disadvantage is that the necessary amount of cross-language glue can make applications cumbersome to write, deploy, and maintain. An alternative is offered by scalable languages, which can be used for many different applications, ranging from small scripts to very large systems. An important aspect of a scalable language is that it itself is extensible and malleable. It should be possible to define very high-level libraries in it, which act in effect as specialized domain specific languages. The advantages of this approach is that it leads to more regular system designs, gives better static checking, makes applications easier to deploy, and increases their reliability. In this talk I'll describe the design principles of the Scala programming language, which has scalability as its primary design objective. Scala combines lightweight syntax with strong static checking on a Java-compatible platform. It encourages the embedding of domain-specific languages as high-level libraries. I discuss how Scala affects systems design and discuss its suitability for large scale industrial deployment. Martin Odersky 13:00 01:00 Ferrer osi Open Source Initiative Podium English The Board of Directors of the Open Source Initiative (OSI) will cover recent activities of the organization in this presentation, talk about the adoption of open source throughout the whole world and discuss the future direction of the OSI, such as the introduction of a membership program. The Open Source Initiative (OSI) is the steward of the Open Source Definition (OSD) and is the community-recognized body for reviewing and approving licenses as OSD-conformant. The OSI is actively involved in Open Source community-building and education. OSI Board members frequently travel the world to attend Open Source conferences and events, meet with open source developers and users, and to discuss with executives from the public and private sectors about how Open Source technologies, licenses, and models of development can provide economic and strategic advantages. Michael Tiemann 14:15 00:15 Ferrer the_linux_defenders Lightning Talks Lightning-Talk English Open Invention Network (OIN), a collaborative enterprise that enables open source innovation and an increasingly vibrant ecosystem around Linux, has unveiled the Linux Defenders program, which is designed to make prior art more readily accessible to patent and trademark office examiners, increase the quality of granted patents and reduce the number of poor quality patents. Keith Bergelt will talk about how the open source community is leading the charge in market-based patent reform. Its Linux Defenders program offers the Linux and broader open source community a unique opportunity to harness its collaborative passion, intelligence, and ingenuity to ensure Linux’s natural migration to mobile devices and computing. He will also detail how this landmark program will benefit open source innovation by significantly reducing the number of poor quality patents that might otherwise be used by patent trolls or strategics whose behaviors and business models are antithetical to true innovation and are thus threatened by Linux. The Linux Defenders website is located at http://www.linuxdefenders.org. Co-sponsored by the Software Freedom Law Center and the Linux Foundation, Linux Defenders is a first-of-its-kind program which aims to reduce future intellectual property concerns about meritless patents for the Linux and open source community. The program is designed to accomplish this by soliciting prior art to enable the rejection of poor quality patent applications; soliciting prior art to enable the invalidation of poor quality issued patents; and soliciting high quality inventions that can be prepared as patent applications or defensive publications. Keith Bergelt http://www.linuxdefenders.org/ 14:30 00:15 Ferrer small_sister Lightning Talks Lightning-Talk English When the European data retention directive becomes law in all member nations governments will store who's e-mailing whom and who's phoning whom. This is bad news for citizens and has a devastating effect journalists and bloggers who need to protect their sources, especially whistleblowers. The Small Sister Project created a tool, SmallMail. It adds anonimity to e-mail even when data retention is in effect. So SmallMail delivers e-mail privacy as it was meant to be: you decide what happens with your data. When needed and allowed people can deliver a message totally anonymous. The talk highlights the tools and then deals with the technical details of getting from A to B. Privacy and anonymity are complicated, but the tool is not. We build on the strong foundation laid by the Tor Project. The SmallMail engine is technically interesting, but quite easy to understand. In 15 minutes you can learn how simplicity and free software solve the problems posed by complex systems. The Small Sister Project tries to create a digital environment for all users to have a privacy-friendly system where personal data is properly secured So we try to create: * A toolkit that is very simple to install and acts like a flushot for a computer to add privacy/security * Sufficient information for people to empower themselves to secure systems and are aware of privacy-issues * Software that is the missing glue for what already exists and helps us reach our goals Peter Roozemaal http://www,smallsister.org 15:00 00:15 Ferrer flossmetrics Lightning Talks Lightning-Talk English The talk will show the main results of the FLOSSMetrics project. In particular, it will show how to obtain data about the history of software development of more than 2,000 FLOSS projects, which kind of data it is and how it can be used, and some results of using it in a research environment. FLOSSMetrics is collecting data from the CVS/SVN repos, mailing lists and issue tracking systems of several thousands of FOSS projects, and collecting all of it into a database that is offerered to researchers and others for data mining. See http://melquiades.flossmetrics.org for the data currently been offered. The project will end in August 2009, and more data and more projects are expected in the meantime. Jesus M. Gonzalez Barahona http://flossmetrics.org 15:15 00:15 Ferrer bazaar Lightning Talks Lightning-Talk English This talk will give a quick introduction to Bazaar, the friendly distributed version control system. It will highlight the benefits of using distributed version control over a centralized approach and what features make Bazaar a perfect match for this kind of collaboration. Bazaar is a distributed version control system that Just Works. While many similar systems require you to adapt to their model of working, Bazaar adapts to the workflows you want to use, and it takes only five minutes to try it out. People have used it to version pretty much anything: single-file projects, your /etc directory and even the thousands of files and revisions in the source code for Launchpad, MySQL and Mailman. Lenz Grimmer http://bazaar-vcs.org 15:30 00:15 Ferrer caiman_opensolaris_distribution_constructor Lightning Talks Lightning-Talk English The presentation will give an overview about building your own customized OpenSolaris distribution. The presentation will discuss the new distro constructor being released with OpenSolaris 11.2008 and demonstrate on how to use it. The Distribution Constructor project is building a set of GUI and command-line tools allowing users to build an install image from a package repository. The distribution constructor tools accept input from the user and process a set of repository packages into one or more media images which can be utilized to install an OpenSolaris distribution. The Distribution Constructor package is available in the pkg.opensolaris.org repository as of build 99, its name is SUNWdistro-const. Some basic documentation is available. The OpenSolaris 2008.11 distribution is built using this tool beginning with the build 98 ISO images. A future phase of the project will add the ability to generate an installable distribution using an existing installed system as its input, rather than a set of packages in a repository. This would be either an enhancement to, or replacement for, the existing Flash Installation functionality. Key Requirements and Functionality (2008.11 Release) * A command-line interface to run the construction process * A manifest file format consumed by the constructor * Modifications to the Target Instantiation module built in Dwarf Caiman and Slim Install to create the file system structure needed for building thedistribution * Modifications to the Transfer module to support installing a set of IPS packages * A plug-in interface that the user or other projects can use to perform their image-specific customizations * Checkpointing interfaces which allow a build to be debugged, and restarted * A module for constructing a boot archive usable on installable media * Support for localization of the image produced * An installable package containing the distro constructor Stefan Schneider http://opensolaris.org/os/project/caiman/Constructor/ 16:00 00:15 Ferrer apache_felix Lightning Talks Lightning-Talk English The OSGi framework allows you to install, update and delete components without restarting the framework. Together with the deployment admin specification and custom resource processors, you can dynamically deploy both OSGi and non-OSGi applications. The talk will demonstrate how to update OSGi bundles and other resources. Apache Felix is a community effort to implement the OSGi R4 Service Platform, which includes the OSGi framework and standard services, as well as providing and supporting other interesting OSGi-related technologies. The ultimate goal is to provide a completely compliant implementation of the OSGi framework and standard services and to support a community around this technology. Marcel Offermans http://felix.apache.org/ 16:15 00:15 Ferrer opsview Lightning Talks Lightning-Talk English The past, present and future of the project. This talk will coincide with Opsview v3.0 release scheduled for early February 2009. Opsview is network monitoring software that significantly extends the functionality of Nagios and integrates tools such as MRTG, NMIS, RANCID and Net-SNMP. Opsview is developed using Catalyst web framework and MySQL database. James Peel http://www.opsview.org 16:30 00:15 Ferrer marionnet Lightning Talks Lightning-Talk English Overview of Marionnet, advantages towards different solutions, how it proved to be a necessary tool, how teaching networking has become less painful. Marionnet is a virtual network laboratory: it allows users to define, configure and run complex computer networks without any need for physical setup. Only a single, possibly even non-networked GNU/Linux host machine is required to simulate a whole Ethernet network complete with computers, routers, hubs, switches, cables, and more. Support is also provided for integrating the virtual network with the physical host network. As Marionnet is meant to be used also by inexperienced people, it features a very intuitive graphical user interface. Marionnet is written in the mostly functional language OCaml and depends on User Mode Linux and VDE for the simulation part. Marco Stronati http://www.marionnet.org/ 17:00 00:15 Ferrer lxde Lightning Talks Lightning-Talk English The talk will present - the background of LXDE - its developer team and community in Taiwan, Asia and worldwide - show the different LXDE components - offer insights into design principles and ideas of the developer team for gtk+ - show an example how to make a package of LXDE - show how to translate a LXDE component - show ways to join the LXDE team and community "Lightweight X11 Desktop Environment", is an extremely faster, performing and energy saving desktop environment started by Taiwanese hacker Hong Jen Yee aka PCMAN in 2005. Today it is maintained by an international community of developers. It comes with a beautiful interface, multi-language support, standard keyboard short cuts and additional features like tabbed file browsing. LXDE uses less CPU and less RAM. It is especially designed for computers with low hardware specifications like netbooks, mobile internet devices (MIDs) or older computers. LXDE can be installed with distributions like Ubuntu or Debian. Applications running on these systems will run with LXDE. The source code of LXDE is licensed partly under the terms of the General Public License and partly under the LGPL. LXDE has recently been included as a standard desktop in Fedora and Mandriva and will also be offered in the upcoming Debian release. Mario Behling http://lxde.org 17:15 00:15 Ferrer camelot Lightning Talks Lightning-Talk English Learn how to create a desktop application from scratch in 15 minutes, the same way you are used to create Django applications. We will design a database model, and create the database and the graphical interface from it. Then we will demonstrate how to adapt this application to suit your particular needs. A python QT GUI framework on top of Elixir / Sqlalchemy inspired by the Django admin interface. Start building desktop applications at warp speed, simply by adding some additional information to you Elixir model. Erik Janssens http://www.conceptive.be/projects/camelot/ 17:30 00:15 Ferrer hackable1 Lightning Talks Lightning-Talk English There is still a void for open source developers having their own platform for mobile development. The current choice is between Google, Nokia and Intel. Hackable1 intends to close this gap and offers desktop developers a quick start in minutes. No longer "fighting" with scratchbox or Openembedded: mobile development like on your desktop and with similar speed. If you have been developing for the desktop you will feel at home in no time. Hackable1 is based on Debian thus brings the power of 1500 DDs with it. It implements the GNOME Mobile stack and comes with a basic suite of phone applications: a dialer, a SMS and contacts application. Mobile devices are becoming ubiquitous and hackable1 is intended to bridge from desktop development to embedded development. It is an area where Open Source has a chance to be from the start ahead of the closed source competitors. We just need to do it! hackable:1 is a Debian based community distribution for hackable devices implementing the GNOME Mobile stack. Currently it runs on the Neo Freerunner from Openmoko but other devices will be supported soon too. As I have been developing myself on and for mobile platforms for several years now the main goal was to bring mobile development to all open source developers in minutes: mobile devices are the next "revolution" in computing and we should not leave the field to Google and Co. Hackable:1 comes with the full development environment, can be installed in minutes and provides an environment like on your desktop and allows for similar speeds. Bearstech (the french distributor of the openmoko phones) supports the development but a key point is community involvement - no decisions behind closed doors, everything is done in public on IRC and mailing lists. Marcus Bauer http://www.hackable1.org/ 18:00 00:15 Ferrer bug Lightning Talks Lightning-Talk English This lightning talk will cover the basics of the BUG platform and show a brief working demo. We will show aspects of the Linux OS running and focus on the OSGi service layer and how Java applications can easily be written to work with custom hardware devices. BUG is an open source hardware and software gadget creation platform. There are no proprietary or closed software components running on the BUG CPU. New devices can be created by snapping a variety of hardware modules (camera, motion sensor, GPS, LCD Touchscreen, WiFi, 3g, etc.) onto a small Linux base computer to make things like GPS enabled motion detectors, alarms, crowdsourced input devices, and wireless weather stations. The hardware schematics for the device are GPL and the computer runs Linux, FOSS Java, and OSGi to enable a dynamic service runtime. An SDK is available that's based on Eclipse and we have a application collaboration website based on Ruby on Rails. Ken Gilmer http://www.buglabs.net 18:15 00:15 Ferrer usbpicprog Lightning Talks Lightning-Talk English We'll introduce for the first time to the public usbpicprog, a brand new programmer for the PIC microcontrollers by Microchip. The different stages of development, a basic overview of how it works and comparison to alternatives will be presented. usbpicprog, a brand new programmer for the PIC microcontrollers by Microchip. Software works on multiple OSses using wxWidgets. It's the first cheap, small, usb-supported programmer, with active development. Frans Schreuder http://www.usbpicprog.org 18:30 00:15 Ferrer gemvid Lightning Talks Lightning-Talk English In this talk, we will first introduce Gemvid, a system that allows the monitoring of animals in their own environment for an extended period of time. Then, we'll show how we demonstrated the sensitivity, reproducibility and stability of the system. Finally, we'll highlight some issues and interesting points for the future of Gemvid. Gemvid is a monitoring system that quantifies overall free movements of rodents without any markers, using a commercially available CCTV and a motion detection software developed on a GNU/Linux-operating computer. The application is based on software modules that allow the system to be used in a high-throughput workflow. Jean-Etienne Poirrier http://www.bioinformatics.org/gemvid/ 13:00 01:00 Lameere emb_openwrt_uci Embedded Podium English Most embedded routers and similar devices have traditionally limited themselves to a very static system, typically providing the web interface as the only means of doing any configuration. OpenWrt intends to solve this problem in a generic way by providing a structured, extensible and modular configuration system, which does not limit itself to being the backend of a web interface. John Crispin Felix Fietkau 14:00 01:00 Lameere emb_wt_toolkit Embedded Podium English Pieter presents [[http://www.webtoolkit.eu/wt Wt], an open source web toolkit that brings state-of-the-art cross-browser, AJAX-enabled web application development to C++ programmers who have little or no experience in web technologies. A web interface to an embedded system provides many benefits, such as remote control without software installation, and comfortable device operation and configuration without the constraints and the cost of an awkward user interface due to limited space on the device itself. At the same time, web interfaces are becoming the preferred choice for application development of various types, driven by rapid advances in web browser technology, (wireless) network availability, and low deployment costs. [http://www.webtoolkit.eu/wt Wt] is an open source web toolkit that brings state-of-the-art cross-browser, AJAX-enabled web application development to C++ programmers who have little or no experience in web technologies. We present some of its features and show how it resembles typical desktop GUI toolkits from a programmer point of view. Because of its high performance, it is popular for large deployments on Internet and intranet servers down to small deployments on embedded systems. We discuss its suitability for embedded systems compared to alternative approaches, and demonstrate some capabilities using a 200MHz ARM device. Pieter Libin Wt website 15:00 01:00 Lameere emb_voltage_regulator Embedded Podium English Every uA is sacred: A dynamic voltage and current regulator interface for the Linux kernel The Linux kernel voltage and current regulator subsystem is designed to provide a standard kernel interface to device drivers and board level code in order to control system voltage and current regulators. The subsystem is designed to allow systems to dynamically control their regulator power output in order to save system power and prolong battery life. This talk will describe the regulator subsystem and discuss how the subsystem can be used to reduce dynamic and static system power consumption. Liam Girdwood 16:00 01:00 Lameere emb_bug Embedded Podium English [http://buglabs.net BUG] is a device that takes the concept of a standard PC, turns it inside out, and makes it fit in your hand. Using open source hardware and software, applications can be created with previously non-existent device configurations. This talk will discuss the BUG platform in general, and our use of OpenEmbedded and Poky Linux. No proprietary or commercial tools, drivers, or applications are used. If there is interest we may also get into some application development and show some existing apps. More information on BUG is available at [http://buglabs.net]. Also giving away two BUGS in the devroom. Ken Gilmer 17:00 01:30 Lameere emb_ptxdist Embedded Podium English PTXdist is a "make your own distribution" build system, based on Bash, Kconfig and GNU Make. Dealing with embedded systems is a complicated thing: you have to take care of toolchains, cross compiling and, in industrial projects, most of all: reproducability and testability. PTXdist is a "make your own distribution" build system, based on Bash, Kconfig and GNU Make. Making a root filesystem for a target box can be as easy as 'ptxdist go', but the focus is on "executable documentation", not distribution. We care about upstream of the managed softare, separate our patches and try to be part of the world domination project by finding bugs in other people's open source software. Robert Schwebel 13:15 00:15 H.1301 kde_welcome KDE Other English Welcome to the KDE developer room at FOSDEM 2009.

Matthias Hopf 15:00 01:00 H.1309 xorg_rebuilt_desktop X.org Podium English Graphics drivers under Linux have seen the most significant changes since X was first ported in the last year. The X server can now run as an unprivileged process; kernel panic messages can be displayed while graphics are active; graphics applications can use virtual memory to store GPU data. In the kernel, these changes include the new Graphics Execution Manager (GEM) and kernel-based video mode setting (KMS). Beyond the kernel, the second version of the Direct Rendering Interface X extension (DRI2) unifies the X and OpenGL image storage space. This talk will describe the kernel and user-space changes along with the other kernel changes necessary to support the new code. Finally, the audience will be encouraged to participate in a discussion about future plans in this area.

Francesco Crippa Luca Foppiano Func project page 17:00 01:00 H.2213 fedora_sugar Fedora+CentOS Podium English Introduction to [http://sugarlabs.org/ Sugar and SugarLabs], strategic importance it might have for Fedora and GNOME, and synergy with other projects Fedora cares about. Greg DeKoenigsberg Tomeu Vizoso 18:00 01:00 H.2213 fedora_augeas Fedora+CentOS Podium English [http://augeas.net/ Augeas] is a configuration editing tool. It parses configuration files in their native formats and transforms them into a tree. Configuration changes are made by manipulating this tree and saving it back into native config files. One of the many things that makes Linux configuration management the minefield we all love is the lack of a local configuration API. The main culprit for this situation, that configuration data is generally stored in text files in a wide variety of formats, is both an important part of the Linux culture and valuable when humans need to make configuration changes manually. AUGEAS provides a local configuration API that presents configuration data as a tree. The tree is backed directly by the various config files as they exist today; modifications to the tree correspond directly to changes in the underlying files. AUGEAS takes great care to preserve comments and other formatting details across editing operations. The transformation from files into the tree and back is controlled by a description of the file's format, consisting of regular expressions and instructions on how to map matches into the tree. AUGEAS currently can be used through a command line tool, the C API, and from Ruby, Python, and OCaml. It also comes with descriptions for a good number of common Linux config files that can be edited "out-of-the-box." Raphaël Pinson Augeas 13:00 00:15 H.2214 opensuse_welcome openSUSE Other English Welcome to the openSUSE developer room at FOSDEM 2009. Martin Lasarsch 13:15 00:30 H.2214 opensuse_obs_trust openSUSE Podium English The [http://en.opensuse.org/Build_Service openSUSE build service (obs)] offers everyone the opportunity to build packages for many Linux distributions with relatively little effort. Hence the amount of available versions and variants per package is comparatively high. Therefore we need a powerful but also simple instrument to evaluate these packages, which are immediately available at the openSUSE software portal. A first approach will be an individual rating of developers working with obs. Marko Jung 13:45 00:45 H.2214 opensuse_community openSUSE Podium English This talk gives you an overview about the openSUSE community. What we have, what we need. It also covers some topics from the mailinglists, like Weekly-news i18n, plans for language specific news.o.o, and why i18n is important for us. The Talk will also have short overview about the upcoming openSUSE spokesperson program. Dinar will also talk about the Contrib repository. Dinar Valeev 14:30 00:15 H.2214 opensuse_build_service_overview openSUSE Podium English Introduction into the [http://build.opensuse.org openSUSE Build Service], why it was created, what are the goals it wants to achieve and a brief overview about its components. Adrian Schroeter 14:45 00:45 H.2214 opensuse_obs_collaboration openSUSE Podium English This talk explains how to use the Collaboration features of the openSUSE Build Service. Its based on two openSUSE repositories that use them: openSUSE:Factory:Contrib and openSUSE:Factory. Hendrik Vogelsang openSUSE Contrib 15:30 00:45 H.2214 opensuse_obs_crossdev openSUSE Podium English The Cross Development in OBS feature is now integrated into normal OBS development. It allows you to build, test, run applications for other processor architectures using a combination of emulators and crossbuild. Emulators are already a normal part of OBS. An analysis has been made of the different ways to implement Cross Build to result in better interoperability with existing linux distributions for other architectures. The goal was to implement Cross Development as an orthogonal feature, and to glueless implement openSUSE, Fedora, Debian, Ubuntu for embedded architektures like ARM, sh4, mips in the same way as is done already by OBS for x86 and powerpc architectures. Martin Mohring openSUSE Build Service 16:15 00:45 H.2214 opensuse_create_your_own openSUSE Podium English This talk will explain briefly how you create your own openSUSE based Linux distribution installation media and Live media with the openSUSE Build Service. It includes a brief introduction to kiwi-instsource (which was presented as an outlook last year) and the way we define products; how the buildservice creates an installation source from that. = Gory details: * kiwi in general (few minutes) * kiwi-instsource: purpose, implementation, xml extension, metapackages (10-15 minutes) * product definition file (5-10 minutes) * plugging together: product converter, necessary permission, vision of the release process, target groups etc. (10-15 minutes) = Demo: Jan-Christoph will demonstrate the following: * setup your own project * how to get this marked as product project * how to set base repos * how to define a product (package groups) * build a product: instsource(ftp repo, dvd) and live medium Jan-Christoph Bornschlegel 17:00 00:45 H.2214 opensuse_studio openSUSE Podium English SUSE Studio is a new web application to build openSUSE based appliances. It provides an easy to use interface to quickly create images for live CDs, bootable USB sticks and VMware. It's also possible to conveniently customize software selection, configuration and theming of the appliances. Third party software may be integrated through coupling with the openSUSE Build Service. Studio's testdrive feature allows users to run the appliance via the web interface for testing and further configuration. We will present the concepts behind SUSE Studio and demonstrate how to easily create a customized openSUSE version in five minutes. Daniel Bornkessel Cornelius Schumacher SUSE Studio 17:45 00:30 H.2214 opensuse_legal openSUSE Podium English Every community distributions have to deal with legal issues. The talk shows what kind of pitfalls we have in our daily distribution work and how to solve them. This will only work with the upstream developers of the projects and most of the work will be done for every distribution again. Jürgen Weigert 18:15 00:45 H.2214 opensuse_apport openSUSE Podium English Apport for automatic crash reporting on openSUSE. Many application crashes remain unreported due to different reasons: * the crash is silently ignored since no core file is produced * existing crash handlers like bug-buddy or Dr. Konqi are desktop application specific * the crash is not easy to reproduce * the location to report the crash is unknown Apport gives you an easy way to solve these problems. Jan Blunck Apport website 14:00 02:00 AW1.105 osi_public_meeting Open Source Initiative Meeting English The Open Source Initiative (OSI) will hold its public meeting at FOSDEM. This meeting is open to everyone and the agenda is very flexible. We can discuss recent activities of the OSI, the future direction of OSI, and other topics of importance to the open source community. Michael Tiemann Martin Michlmayr 17:00 02:00 AW1.105 moz_xul Mozilla Workshop English Open discussion with [http://www.mozilla.org/projects/xul/ XUL] communities.

Richard Frith-Macdonald 14:00 01:00 AW1.117 geo_scalable_ogo GNUstep+OpenGroupware+Etoile Podium English This presentation presents ScalableOGo, a standards compliant free software groupware server. Scalable OGo (SOGo) is a free groupware server focused on scalability instead of depth in functionality. The web interface uses human readable URLs and can be accessed according to REST web service ideas. The server stores data in the iCalendar/vCard formats and has broad support for theCalDAV/GroupDAV protocols. Helge Heß 15:00 01:00 AW1.117 goe_objc_gnustep GNUstep+OpenGroupware+Etoile Podium English This presentation explores the free tools that the GNUstep project provides for writing cross-platform Objective-C software. Objective-C is most known for being the language of choice of Apple and being the "native" language for Apple Mac OS X and iPhone development. Unfortunately, while Objective-C is a fantastic language, the development tools provided by Apple are designed to lock developers into a closed Apple-only environment. GNUstep provides an alternative, free implementation of the OpenStep specification (the core Objective-C libraries), largely compatible with the Apple Mac OS X Cocoa implementation, and a number of tools that allow Objective-C software to be developed and easily distributed across a number of platforms, including GNU/Linux, *BSD, Apple Mac OS X and Microsoft Windows. Nicola Pero 16:00 01:00 AW1.117 geo_ws_objc GNUstep+OpenGroupware+Etoile Podium English An overview of web services and a free software implementation to make them easy Objective-C programmers (GNUstep and MacOS-X/Cocoa).

Peter Saint-Andre 13:00 01:00 AW1.121 debian_video_team Debian Podium English We discuss the provisions of video coverage of [http://www.debconf.org/ DebConf] and Debian mini-conferences, starting in 2005. In particular, we describe the development of supporting software from simple scripts to a software video mixer and database of recordings with a web front-end. Ben Hutchings Holger Levsen DVswitch 14:00 01:00 AW1.121 debian_ultimate_database Debian Podium English Ultimate Debian Database (UDD) gathers a lot of data about various aspects of Debian in an SQL database. It allows users to easily access and combine all this data. We will describe the current status of UDD, explain how you can make use of it, and give some examples of cool stuff that you can already learn about Debian using it and ways it could be used to improve Quality Assurance in Debian Stefano Zacchiroli Lucas Nussbaum 15:00 01:00 AW1.121 debian_data_export Debian Podium English DDE (Debian Data Export) is a simple interface to remotely access Debian information. It is designed to be simple to query, and to back the implementation of nice things such as package name autocompletion on all input fields in Debian web pages, or to make more data easily available to Debian utilities and package managers. On top of all that, it is a RESTful Web 2.0 middleware designed to enable AJAX mashups. What more can you ask? Come and have a look. Enrico Zini 16:00 01:00 AW1.121 debian_openmoko Debian Podium English Because Debian calls itself "the universal operating system", it was inevitable that it would have come to the first F/LOSS-friendly mobile phone, the Openmoko Neo FreeRunner. Debian on the Openmoko FreeRunner is not a new port nor a new distribution, but instead a different underlying system for the various Openmoko distributions (originally based on OpenEmbedded). At the moment the Debian FreeSmartphone.Org team has focused its works mainly on the FreeSmartphone.Org stack, which is intended not only for the Openmoko devices, but as a general stack for all mobile phones. Luca Capello 17:00 00:30 AW1.121 debian_nas Debian Podium English Network Storage Devices (NAS) are gaining popularity and are available quite inexpensively. For most customers, they are basically just a hard drive that you connect to the network for file storage. In reality, these devices are complete, even if fairly low-end, computers - and Debian can be installed on some of them. This talk will discuss a number of devices that are currently supported and cover some platforms that may be supported in the future. Martin Michlmayr 17:30 00:45 AW1.121 debian_grid Debian Podium English Grid Computing with Debian, Globus and ARC - collaborations in high-performance computing beyond programming and packaging. Debian is known for being developed from its userbase. The individuals mutually trust each other, implemented mechanisms for peer review and have the technical support for authorisation and authentication. This way, the workload to provide the software packages for the compute infrastructure is shouldered by many individuals. Grid computing takes this collaboration further. Here, research groups offer access to their local resources not only to other research groups, but they may even grant the right to admit users to virtual organisations - much like the Debian keyring. The presentation presents an overview on current grid middleware and computational grids established. The Globus grid middleware and its Debian packaging are explained, together with the packages of the Advanced Resource Connector (ARC). Today, the most usecases of the technology are the sharing of the computational resources like plain compute power or storage. With the advent of these packages in the Debian main distribution, the adoption of these packages is expected to become more of a commodity to exchange computational workflows, share the burden to maintain rapidly changing data, or control the limited access to special hardware. The speakers are researchers at the Universities of Copenhagen, Lübeck and Uppsala. With funds from several national and international projects in high-energy physics or grid computing, the three are contributing to the development of the ARC grid middleware - and for the provisioning of its Debian packages. Anders Wäänänen Steffen Möller Mattias Ellert 18:15 00:45 AW1.121 debian_dpl Debian Podium English After being the person in the hot seat for most of a year, Steve wants to give some details about how the job works and how he thinks it should work. This is *not* meant to be an early start to an election campaign, but instead an objective discussion of the role of the DPL within the Debian Project. Steve McIntyre 13:00 00:15 AW1.124 ada_informal_discussions Ada Podium English Welcome talk and Ada informal discussions (Adalog and Adacore Stands) Dirk Craeynest 13:15 00:45 AW1.124 ada_bof_0 Ada Other English Lunch break and informal discussions. Valentine Reboul 14:00 01:00 AW1.124 ada_intro Ada Podium English This presentation exposes the main features of the Ada language, with special emphasis on the features that make it especially attractive for free software development. Jean-Pierre Rosen Free software from Adalog 15:00 01:00 AW1.124 ada_gps Ada Podium English [https://libre.adacore.com/gps GPS, the GNAT Programming Studio], is a powerful and simple-to-use Integrated Development Environment that serves as portal to the GNAT toolchain. It provides customizable settings, browsing, syntax-directed editing, easy integration with third party tools such as Version Control Systems, source navigation, dependency graphs, and more. Built entirely in Ada, GPS is designed to allow programmers to get the most out of GNAT technology. Vincent Celier GPS 4.3 16:00 01:00 AW1.124 ada_in_debian Ada Podium English Ludovic Brenta will explain his work as the principal maintainer of Ada in [http://www.debian.org Debian], and the [http://www.ada-france.org/debian/debian-ada-policy.html policy that unites all Ada packages], thereby making Debian the best free Ada development platform in the world. The Debian Project is an association of individuals who have made common cause to create a free operating system. The development processes are open to the public and anyone can contribute. The strict Debian Free Software Guidelines are the basis of the Open Source Definition. The resulting operating system consists of tens of thousands of Free Software packages and is renowned for its reliability, thanks to Debian's extensive quality assurance policy. Debian GNU/Linux supports 12 hardware architectures and 4 more are in various stages of development. Debian GNU/Hurd, Debian GNU/NetBSD and Debian GNU/kFreeBSD are works in progress. Several other distributions use Debian as their foundation. Ludovic Brenta 17:00 01:00 AW1.124 ada_annex_e Ada Podium English The [http://www.adaic.com/standards/05rm/html/RM-E.html Distributed Systems Annex] is an optional part of the Ada language that allows writing programs that are distributed across several computers. Each "partition" of the program, running on one machine, communicates with the others by means of remote procedure calls and shared data structures. Ada provides facilities to make this communication completely transparent to the programmer. Thanks to it, writing a distributed program is no more complex than writing a monolithic one. Indeed, it is possible to recompile a distributed program to make it either distributed or monolithic with no changes to the program source. There are two Free Software implementations of Annex E for GNAT, the GNU Ada compiler: GLADE and its successor [https://libre.adacore.com/polyorb PolyORB], both licensed under terms of the GPL. Thomas Quinot 18:00 01:00 AW1.124 ada_narval Ada Podium English NARVAL stands for "Nouvelle Acquisition temps Reel Version 1.6 Avec Linux". It is a distributed data acquisition software system that collects and processes data from nuclear and particles physics detectors. NARVAL replaces an older system based on C, Fortran and proprietary technologies with Ada and Debian GNU/Linux and is itself Free Software. In order to ensure maximum data safety most of the program is written in Ada with heavy use of Annex E, the Distributed Systems Annex. Software engineers and physicists from several countries use this system for fundamental research. The talk will present the NARVAL architecture in detail with some focus on the multi-tasking dataflow core and the configuration done through Annex E. Xavier Grave Centre National de la Recherche Scientifique 13:15 00:30 AW1.125 java_state_openjdk Free Java Podium English A summary of the past year's accomplishments, some views on what remains to be done, and a look ahead to the content of JDK 7 and the process by which it will be developed. And where are we with OpenJDK 6 today and where will we go tomorrow? The origins and initial design decision of the project will be discussed and well as possible future directions of the project. Joe Darcy Mark Reinhold 13:45 00:30 AW1.125 java_jigsaw Free Java Podium English One of the most significant changes in JDK 7 will be to modularize the code base, to modularize the platform, and to enable the modularization of applications, all via [http://blogs.sun.com/mr/entry/jigsaw Project Jigsaw]. Mark will discuss how the introduction of language-level modules, in concert with corresponding updates to the tool chain and the runtime environment, should to allow applications and libraries written in Java to be distributed as sensible and familiar [http://blogs.sun.com/mr/entry/packaging_java_code distro-specific packages]. Mark Reinhold Project Jigsaw http://blogs.sun.com/mr/entry/packaging_java_code 14:15 00:30 AW1.125 java_small_changes Free Java Podium English In addition to modularity support, JDK 7 is also planned to have a number of small language changes. Unlike previous JSRs to change the Java programming language, this project will be taking input from a public call for proposals phase. Joe will be talking about criteria developed to evaluate language changes and the current status of the project. Joe Darcy 15:00 00:30 AW1.125 java_state_icedtea Free Java Podium English Objective: To introduce IcedTea and lead into the talks given by the other IcedTea developers present. Where is IcedTea now?

Karl Helgason 13:00 00:15 AW1.126 ooo_welcome OpenOffice.org Other English Welcome to the OpenOffice.org developer room at FOSDEM 2009. Jürgen Schmidt 13:15 01:00 AW1.126 ooo_uno OpenOffice.org Podium English UNO is the object model underlying OpenOffice.org. With its by now long and winding history, this might be a good time to reflect on its design and implementation, its shortcomings and strengths. In this talk we will look at details in various areas of UNO, tell the occasional anecdote, and generally have fun. Stephan Bergmann 14:15 01:00 AW1.126 ooo_java OpenOffice.org Podium English OpenOffice.org entry barrier is quite high - people need lot of time to learn how to develop for the OpenOffice.org. This talk is more or less theoretical and it tries to cover all possible areas. We will define common terms, describe UNO Java bridge, go through documentation and explain how to read it, where to find information we need. Introspection interface with tool examples will be described too. And finally, we will take a look at the OpenOffice.org on the server. This talk should lower entry barrier for developers and prepare them for OpenOffice.org development. Robert Vojta 15:15 02:00 AW1.126 ooo_extensions_in_java OpenOffice.org Workshop English The workshop focused on the creation of an extension in Java with the OpenOffice.org API plugin for NetBeans. The attendees can choose if they want to create a smart tag, or an options page demo or if they want to create a weather forecast demo. Two of the demos make use of external functionality and show how easy it can be to make use of web services or external libraries. The attendees will by guided through a detailed tutorial and will create their extension of choice step by step. Ideally the attendees should bring their own laptop into the workshop. And they should have installed NetBeans 6.5, Java 1.6, OpenOfice.org and the OpenOffice.org SDK. A CD with installation programs for the common platforms and the whole workshop material will be available in the workshop room as well. If you have no laptop, no problem watch your neighbour over the shoulder and work together. Or simply listen and watch what the speaker is doing ;-) Jürgen Schmidt 17:15 01:00 AW1.126 ooo_gfx_hackers OpenOffice.org Podium English This talk will give an introduction to areas inside OOo amenable to graphics hackers - stuff that has the desirable property of instant visual gratification. Layout: there's currently work underway to give OOo's dialogs an auto-layouting facility. Besides work on the layouting core, there's also help solicited for converting existing dialogs to the new layout-enabled scheme. Canvas: the new OOo rendering subsystem, and what it can do; showing a prototype of an OpenGL-based implementation plus pointers where interested hackers can start helping Slideshow: probably the easiest way to make an impact to millions of OOo users is to code another Impress 3D slide transition – here's how to do that. Thorsten Behrens 18:15 00:30 AW1.126 ooo_bug_hunting OpenOffice.org Workshop English Jürgen Schmidt 14:00 01:30 Guillissen lpi_1 LPI Certification Other English LPI exam session #1 Klaus Behrla 16:00 01:30 Guillissen lpi_2 LPI Certification Other English LPI exam session #2 Klaus Behrla 10:00 01:00 Janson cobbler_koan Systems Podium English During this talk, we aim to give you an overview of the Cobbler project, explain where we'd like to see it going and explain a few use cases. Cobbler is an installation server, written in Python, which allows for rapid deployment (and re-deployment) of large amounts of physical and virtual machines by defining distributions, repositories, profiles and systems as objects. It's easy to get started with Cobbler, but we ship a lot of advanced features to make it as versatile as possible, so you won't get bored with it. Robert Lazzurs Jasper Capel Cobbler project 11:00 01:00 Janson mysql_ha Systems Podium English There are many ways of how to ensure the availability of a MySQL Server and how to provide additional redundancy and fault-tolerance. In this talk, Lenz will give an overview over some best practices and commonly used HA setups for MySQL. The talk will cover the Open Source components and tools that are frequently utilized, with a focus on Linux and OpenSolaris. The session will also cover MySQL Cluster, the architecture and relationship to the MySQL Server. Lenz Grimmer 12:00 01:00 Janson upstart Systems Podium English This talk takes a trip along the Roadmap for Upstart 1.0, introducing what features will be available. Linux has always traditionally lacked good service management facilities, so much so that the typical daemon doesn't use what ones we have and instead relies on hokey shell scripts. Upstart is being developed to not only solve this problem but also how it, through integration with D-Bus, DeviceKit and similar frameworks, allows service lifecycles to be tied to hardware and system state. Scott James Remnant Official website Wikipedia entry 14:00 01:00 Janson syslinux Kernel Podium English This talk will discuss the x86 boot process, how to make it work in a dynamic system, and the tradeoffs between versatility and reliability. It will also discuss the Syslinux modular interface and how to use it to quickly add new features with a minimum of coding. Originally written during an all-night hacking session in 1994 with the intent to better support the then-ubiquitous install boot floppies, Syslinux has evolved over the years into a widely used boot loader suite with an advanced modular interface, with emphasis on ease of use and reliability. It is now the most commonly used x86 bootloader for removable media, and is increasingly used for conventional hard disk booting as well. H. Peter Anvin 15:00 01:00 Janson ext4 Kernel Podium English This presentation will discuss history of ext4, its features and advantages, and how best to use the ext4 filesystem. The latest generation of the ext2/ext3 filesystems is the ext4 filesystem, which recently left the development status of 2.6.28. With extents, delayed allocation, multiblock allocation, persistent preallocation, and its other new features, it is substantally faster and more efficient compared to the ext3 filesystem. Theodore Ts'o Official website Wikipedia entry 16:00 01:00 Janson slow Kernel Podium English An understanding of the nature of your system workload is an important step in optimizing it for maximum performance on your hardware. I will discuss some useful tools and techniques for evaluating the workload of your FreeBSD system, and identifying the bottlenecks that are limiting performance. Kris Kennaway 17:15 01:00 Janson gsoc Keynotes Podium English Ever wondered what it takes to make a community of more than 180 F/LOSS projects and 5,000+ geeks create great software? In this talk, Leslie Hawthorn will explore the successes and setbacks of [http://code.google.com/soc/ Google Summer of Code], the first global program designed to introduce University students to Free and Open Source software development practices and methodologies. Leslie will discuss the program's inception, history, and impact, and the evolving requirements for managing a large scale global community. She will share lessons learned during the past three years as the program's Community Manager, with an eye to providing audience members with strategies for organizing their own community participation initiative, and provide attendees with an update on [http://code.google.com/p/soc/ Melange], the new work flow application designed to manage *Google Summer of Code* - or similar programs - and Google's first Open Source project developed in the open from the first commit. Leslie Hawthorn Official website 10:00 01:00 Chavanne Security Podium English The speech goal is to show the OWASP testing methodology and how you can implement a software development lifecycle that permit to develop more secure applications. The Open Web Application Security Project (OWASP) wants to deliver free tools and documentation for the Web Application Security. The talk will present the new OWASP Testing Guide v3 that includes a "best practice" penetration testing framework which users can implement in their own organizations and a "low level" penetration testing guide that describes techniques for testing most common web application and web service security issues. OWASP Testing Guide v3 is a 349 page book; we have split the set of active tests in 9 sub-categories for a total of 66 controls to test during the Web Application Testing activity. Matteo Meucci Official website OWASP Website 11:00 01:00 Chavanne freeipa Security Podium English Free Software Identity Management challenges and technical details The presentation will revolve around the problems of building a modern Free Software based Identity Management Solution. The challenges we faced in trying to combine security, ease of used, standards, features, and interoperability with other solutions. The choices we have made for the current code base, and the choices we are facing going forward. The vision and future directions. The presentation will introduce the public to the technologies used, the modifications or additions we performed and will dive into technical details about how we architect the server and the future client components. Simo Sorce Official website Wikipedia entry 12:00 01:00 Chavanne fusil Security Podium English The talk will present how a fuzzer is written and how it works. Then we will analyze a crash. And finally we will see how to report it to the vendor and typical vendor reactions. Fusil the fuzzer is a Python library to write fuzzers and a collection of twenty specific fuzzers: ClamAV, Firefox, mplayer, poppler (PDF), etc. A simple fuzzer can crash most (all?) applications. Victor Stinner Official website List of crashed programs 14:00 01:00 Chavanne mediawiki Collaboration Podium English I'll be going over some of the particular UI and workflow issues in editing, media uploading, and other areas that we intend to tackle, summarize some of the existing work toward those ends, and give a preview our upcoming Wikipedia Usability Initiative. MediaWiki was born in 2002, when Wikipedia's editing activity outgrew the concurrency limits of its original wiki engine. The first 6 years of this open-source wiki platform's development were largely devoted to scaling and performance, ensuring that the world's most editable online encyclopedia could keep up with the number of articles, visitors, and changes that come with being an insanely popular user-written site. But the user interface hasn't changed much since 2003; if anything, packing in more features has made many aspects of the wiki harder to use over time. In 2009, MediaWiki developers are turning their eye towards usability and design issues. As with the scaling problems we've tackled before, we have to be able to target anything from a tiny personal or intranet wiki to the massive Wikipedia sites, making a range of different use cases with different needs... It'll be fun! Brion Vibber Official website Wikipedia entry 15:00 01:00 Chavanne zarafa Collaboration Podium English The Zarafa webaccess plugin system is aimed at allowing developers to add functionality to the Zarafa webaccess, while not requiring them to modify existing system files inside the core of the Zarafa WebAccess software. Zarafa will show how to programm a module and shows the architecture integrations with open source solutions such as Alfresco and Sugarcrm and other community contributions.

Steve Hardy 16:00 01:00 Chavanne caldav Collaboration Podium English Introduction into the CalDAV protocol and related protocols. Overview on OpenSource CalDAV clients and servers, and on libraries for CalDAV development. Attempt to motivate people to implement IETF standard protocols instead of proprietrary ones. CalDAV is a calendaring and scheduling client/server protocol designed to allow users to access calendar data on a server, and to schedule meetings with other users on that server or other servers. Helge Heß 10:00 00:15 Ferrer gnutls_intro Lightning Talks Lightning-Talk English I'll introduce GnuTLS and mention it features over the competition, and talk about problems facing a free software project in an area which has many patents. GnuTLS is a SSL/TLS implementation for the GNU system. SSL/TLS is the network security protocol used by HTTPS, and numerus other network protocols to provide X.509, OpenPGP etc security. Simon Josefsson http://www.gnutls.org/ 10:15 00:15 Ferrer secure_list_server Lightning Talks Lightning-Talk English The talk will start with a very short overview of the history of Mailman and the mailman-pgp-smime project. Some remarks will be made on how to install and configure the software, so that one can try it. Currently supported features will be mentioned, as well as an overview of development plans. One will learn how to contribute to the project; an overview of the revision control system used will be given. Some remarks on the future of the patch will be made: will it be shipped with Mailman itself? If you have used Mailman, both as a subscriber and as a list admin, and if you know what PGP and S/MIME are, you should definitely attend this talk. he Secure List Server, mailman-pgp-smime, is an effort to add support for encryption and authentication to Mailman, the GNU mailing list software. This enhancement enables groups of people to safely cooperate and communicate using email. The patch includes support for both RFC 2633 (S/MIME) and RFC 2440 (OpenPGP) email messages. Development of the patch is made possible by the NLnet foundation. A post to a secure list will be distributed only if the PGP (or S/MIME) signature on the post is from one of the list members. For sending encrypted email, a list member encrypts to the public key of the list. The post will be decrypted and re-encrypted to the public keys of all list members. Joost van Baal http://non-gnu.uvt.nl/mailman-pgp-smime/ 10:30 00:15 Ferrer jtrunner Lightning Talks Lightning-Talk English The talk will be focused on the main features delivered by the JTR Project that enable the seamless distribution of the full spectrum of test-suites that can be written to a set of JTR-enabled nodes making it easy performing distributed test sessions. The JTR Project is a Java distributed testing framework conceived to fill a gap existing today most notably in the open-source world that’s the lack of a single tool that could help in developing from simple to complex test suites in Java with particular emphasis on the stack of backend-technologies embraced by the JEE specification. The JTR Framework is aimed at fastening the development of both functional and stress-test suites for verifying the requirements and robustness of both JSE and JEE projects. The JTR Framework supports you in writing components meant for testing: •standard JSE components / applications •EJBs conforming to both J2EE 2.x and JEE specifications •MOM-based JSE and JEE systems (JMS) •web-services (both document-based and rpc-like) Francesco Russo http://jtrunner.sourceforge.net 11:00 00:15 Ferrer ipn_msockets Lightning Talks Lightning-Talk English We have found two main limitations in Berkeley Sockets API: (1) it has been designed to manage one stack per protocol family (2) there is not a protocol family supporting (fast) multicast for Inter Process Communication (among processes running on the same computer). The virtualsquare team proposes solutions for both problems: (1) the msocket call to support several stacks (implemented in lwipv6 and ipnet) (2) the IPN (inter process networking) protocol family. IPN can be used for many applications: midi, mpeg-ts dispatching, kernel based vde switches.

This project has been released for the spanish community at the beginning of 2008 and by January 2009 it will be translated to english. Right now it is downloadable and before the end of the year we will begin to develop the project through a public SVN. ModularIT is the result of 10 years of hard working from Grupo CPD (www.grupocpd.com) with free software systems and network services. we are a free software companies network from the Canary Islands, Spain. we are interested in presenting the project at FOSDEM. You can find more information (only in spanish until december) by clicking these links: http://www.modularit.org http://www.grupocpd.com/QueHacemos/modularit/PloneArticle_view Agustín Benito http://www.modularit.org 11:30 00:15 Ferrer puppet Lightning Talks Lightning-Talk English After explaining the basics of puppet and some background of the social network Hyves the speaker will discuss how puppet helped Hyves to automate a large set of daily sysadmin tasks. The speaker will also discuss how to automate common sysadmin problems / tasks with puppet and will show how to manage puppet masters and clients on large scale networks (+2000 servers) Puppet is an open-source next-generation server automation tool. It is composed of a declarative language for expressing system configuration, a client and server for distributing it, and a library for realizing the configuration. The primary design goal of Puppet is that it have an expressive enough language backed by a powerful enough library that you can write your own server automation applications in just a few lines of code. With Puppet, you can express the configuration of your entire network in one program capable of realizing the configuration. The fact that Puppet has open source combined with how easily it can be extended means that you can add whatever functionality you think is missing and then contribute it back to the main project if you desire. Marlon de Boer http://reductivelabs.com/trac/puppet 12:00 02:00 Ferrer keysigning Lightning Talks Podium English GPG/PGP and CAcert keysigning party See [http://fosdem.org/2009/keysigning] for details. Joost van Baal Theus Hagen 14:00 00:15 Ferrer freedroidrpg Lightning Talks Lightning-Talk English The talk introduces the game FreedroidRPG, insisting on it being mature and fully playable. We will see what features FreedroidRPG provides, present a few screenshots, explain our interest in having an immersive ambience through dialogs, music and graphics, and mention the unusual history of the game (it started off as a 2D arcade game before evolving into a full featured RPG similar to Diablo). We will explain where we need help from the community. A demo will not be possible in the timeframe of a lightning talk, but a little video may be played. FreedroidRPG is a mature open source sci-fi isometric role playing game. It strives at providing an immersive ambience backed by refined graphics and music tracks. Besides the hack'n'slash action phases, dialogs with dozens of NPCs take care of storytelling. The player can fight with melee or ranged weapons, take control of his enemies by hacking, and remotely execute code on enemy robots. Arthur Huillet http://www.freedroid.org/ 14:15 00:15 Ferrer sgx_engine Lightning Talks Lightning-Talk English Too many game engines expect you to use their code exclusively. But no games company will replace their entire technology with an open source engine, just to utilise one component. Consequently, the only open source technology generally used in professional games are those that come as individual libraries - like Lua, or ODE. In his talk, Steven covers the reason for why monolithic architectures are no good for games development, how to avoid them, and the alternatives - at both a technical and man management level. He covers the principles behind creating interfaces and loosely-couple modules to ensure flexibility, and how to introduce new modules and platforms into the mix. Distinctions are also made between commonly-confused terms such as "engine", "drivers", "domains", "platforms" and "libraries." Finally, an overview of the practical solutions are given, using the SGX Engine as a example covering audio, graphics, input, and scripting. SGX is a 3D graphics engine, based around of series of null drivers and loosely-coupled modules to facilitate an infinitely upgradable engine. It is primarily suited to games and digital TV backdrops, and runs under Windows and Linux, using OpenGL. It is also one of the few Open Source engines to be used in commercial products. Steven Goodwin http://www.sgxengine.com 14:30 00:15 Ferrer musescore Lightning Talks Lightning-Talk English With the first stable 1.0 release in the pipeline, it's time to introduce MuseScore to future users and developers. MuseScore is currently the leading free alternative to commercial score writing software like Sibelius and Finale. With over 50.000 downloads, it has quite some adoption already, but in order to convince music schools world wide, MuseScore's current development team should become a little stronger. FOSDEM 09 will be the first event world wide where MuseScore will be presented MuseScore is a free and open source music scorewriter. MuseScore is a WYSIWYG editor, complete with support for score playback and import/export of MusicXML and standard MIDI files. Percussion notation is supported, as is direct printing from the program. The program has a clean user interface, with fast note editing input with mouse, keyboard or MIDI. MuseScore has binaries available for Linux, Windows and Mac, and is available in more than 10 languages. Thomas Bonte http://musescore.org 15:00 00:15 Ferrer pyroom Lightning Talks Lightning-Talk English The talk will try to answer many questions: * why did this project happen? * how is it organised? * who is this software for? * ... PyRoom is a Free, monochrome, full-screen text editor without buttons, widgets, etc. that helps you focus on one thing and only one: writing. It's written in Python, using Python-GTK bindings. Bruno Bord http://pyroom.org 15:15 00:15 Ferrer ez_find Lightning Talks Lightning-Talk English After a brief overview of the main features and benefits of Apache Solr (an open source embeddable search server), the architecture of eZ Find (the search plugin for eZ Publish, a PHP CMS), will be presented. The main lessons learned around dealing with a mix of structured and non-structured content, multilingual aspects, tuning and the various state-of-the-art features of Solr will be shared with the audience. eZ Find is the enterprise grade search engine used for eZ Publish (a CMS written in PHP, with flexible content modeling). The back-end engine used is Apache Solr. The document/field model of Solr together with its powerful features around faceting, filtering, automatic related content and language features are a 1-to-1 match with the CMS used. But is also capable of integrating various data-sources, such as ERP systems or document collections with the use of plugins. Paul Borgermans http://ez.no/ezfind 15:30 00:15 Ferrer xwiki Lightning Talks Lightning-Talk English The new wysiwyg editor developed by the XWiki team is a cross-browser, GWT-based, stand-alone editing tool that solves a number of known problems in other editors, and brings exciting new features such as concurrent realtime editing. Currently in a beta stage, it was bundled in XWiki Enterprise 1.7 and will become the default editor in the next XWiki release. XWiki is a platform for developing collaborative web applications using the wiki paradigm. Anca Luca http://www.xwiki.org 16:00 00:15 Ferrer tikiwiki_cms_groupware Lightning Talks Lightning-Talk English TikiWiki is a powerful, multilingual Wiki, Content Management System (CMS) and Groupware. Translated to 35 languages, and with an install base of tens of thousands, over 200 people have contributed to the source code and it provides hundreds of built-in features to create all sorts of web sites, intranets and extranets, including support.mozilla.com. The community eats its own DogFood and applies the "Wiki Way" to software development. Written in PHP, it is released as free software (LGPL). TikiWiki is at the crossroads between Wikis and CMS/Groupware. It is so much more than just a wiki. Most wikis are pure wikis. However, is that sufficient? "He who is good with a hammer thinks the world is a nail". While a wiki is a great tool, it is not optimal in many situations. For some things, forums, issue trackers, blogs, etc. are better. That's why there are hundreds of Content Management Systems (CMS) out there. However, many CMS systems are focused on classic publishing, rather than community and collaboration. In TikiWiki, the wiki way is found throughout the application. For example, the wiki syntax works in the forums, and in structured data trackers. Major features of TikiWiki include news articles, forums, newsletters, blogs, a file/image gallery, structured data trackers, translation, polls, calendar, Mobile Tiki (PDA and WAP access), RSS feeds, a category system, a theme control center, and more. When would you need a wiki that is bundled with other features? Find out for yourself in this session what makes TikiWiki unique. TikiWiki CMS/Groupware is a full-featured, tightly integrated, open source, multilingual, all-in-one Wiki-CMS-Groupware, written in PHP and actively developed by a very large international community. Major features include articles, forums, newsletters, blogs, a file/image gallery, a wiki, bug & issue tracker (form generator), a calendar, RSS feeds, a category system, tags, a workflow engine, an advanced user, group and permission system and more. Marc Laporte http://TikiWiki.org 09:00 01:00 Lameere emb_hackable_1 Embedded Podium English [http://www.hackable1.org/ Hackable:1] is a community distribution for hackable devices like the Openmoko Neo Freerunner. It is based on Debian and implements the GNOME Mobile platform. This workshop introduces development for the Freerunner using the hackable:1 software distribution. Pierre Pronchery 10:00 01:00 Lameere emb_solar_control Embedded Podium English Solar hot water systems in particular, and home control in general, provide excellent opportunities for fun geeking. Conventional control is done with various boxes, each of which is very stupid. Everything is proprietary and mostly incompatible with other manufacturers. Wookey decided that a better solution was one smart controller using open technologies, which could do cool stuff like on-line energy logging. He will explain enough about plumbing that the rest of the talk makes sense, then cover the practicalities of the necessary mix of IO: (I2C, 1-wire, digital IO, switching, displays), Software (logging, control scripting, user feedback) and Hardware (Balloonboard+IO). When he's finished you should have enough knowledge to go away and put together your own versatile controller (and solar system), and have an appreciation of the potential of this technology, as well as what work is still needded to make it accessible beyond the world of embedded Linux engineers. Wookey 11:00 01:00 Lameere emb_fire_safety_cert Embedded Podium English Experiences in Development and Certification of Linux-Based Fire Safety & Security Systems As time passes, we rely more and more on software-intensive systems in safety-critical areas, from car brakes to aircraft control systems. A number of standards and certification procedures have been defined to assess the reliability of those products. Linux and open-source software (OSS) are attractive components to use in embedded systems. While some reliability information is available from enterprise systems research, certifiability of OSS in a particular industry is a major project risk. In this presentation, we share our experience in the development and certification of Linux-based fire safety systems. We provide a short introduction in standards objectives and approaches, describe the certification stakeholders and processes, product development challenges and possible solutions. Baurzhan Ismagulov 12:00 00:30 Lameere emb_maemo_beagleboard Embedded Podium English [http://beagleboard.org/ BeagleBoard] is an affordable OMAP3 based development board. [http://maemo.org Maemo] 5 is the next version of Nokia's Linux platform (codenamed Fremantle) and it supports OMAP3 processors. With some patience any BeagleBoard owner can get Maemo Fremantle running on the hardware. This talk will be about creating a BeagleBoard image from the Maemo SDK. I'll go through the current status and how to get involved in the project and how BeagleBoard could be of help in creating software for Maemo devices Juha Kallionen 14:00 01:00 Lameere emb_power_mgmt_omap3 Embedded Podium English As ASIC technology progresses to smaller technology nodes (63nm and and lower), leakage currents become increasingly important. This means that just stopping clocks isn't enough to save enough power to obtain the desired device use times. We need to shut off inactive parts of the ASIC depending on the actual usage. Eg. turn off the camera functionality or the GPU when not in use. We call this dynamic power switching (DPS). This talk will show how TI, Nokia and the community implemented DPS in the linux kernel. We will also discuss other power saving features of OMAP3 and how they are used in the linux kernel. Peter De Schrijver 15:00 01:30 Lameere emb_emdebian_1_0 Embedded Podium English Neil presents the release of Emdebian 1.0 Grip and Crush. == Emdebian 1.0 Grip - a small, binary compatible, Debian == Grip is between 25 and 40% smaller than standard Debian and uses TDebs for localisation. Grip can be easily installed using standard Debian-Installer images or debootstrap and allows for easy mixing of Debian and Grip packages. Grip supports seven architectures using the existing Debian ports: arm, armel, i386, amd64 (test architecture), mips, mipsel and powerpc. Version 1.0 is primarily for developers but is roughly equivalent to Debian in terms of usability and maintenance. Emdebian 1.0 Grip includes packages for a typical XFCE desktop installation. Typical Grip installations are between 25 and 40% smaller than the equivalent Debian installation. This talk covers all the essential features of Grip and will (hopefully) include a demo of using the Debian Installer from Lenny to install Emdebian 1.0 Grip on an Acer Aspire1 netbook. == Emdebian 1.0 Crush - a cross-built tiny Debian developer release == Crush is only available for ARM and consists of a limited package set based around the GNOME Palmtop Environment. Crush installation methods are machine-specific (with support from packages in Debian Lenny) and Crush does not include any kernels. Version 1.0 is only for developers and is significantly more difficult to prepare, install and maintain than either Debian or Emdebian Grip but provides a much smaller installation. Basic root filesystems of 24Mb installed, full GPE GUI installations within 75Mb. This talk covers the limitations of Crush, the practical difficulties inherent in cross-building Debian using packages from Lenny and the improvements being implemented into the next release of Debian (Squeeze) that will make it easier to add support for more architectures for Emdebian Crush 2.0 (based on Debian 6.0 "Squeeze"). Neil Williams 16:30 00:30 Lameere emb_wrapup Embedded Workshop English Wrap-up and feedback session in the Embedded developer room.

Dries Buytaert 09:30 00:45 H.1302 drupal_7 Drupal Podium English What is there to look forward to in Drupal 7, and when can we have it? Learn about CCK-like fields in core, the new testing framework, PDO Database backend, OPML imports, improved time zone support, better file handling, safety from badgers, and the free ponies for everyone. This will be a tour of the user facing and developer oriented features and changes that will make Drupal 7 sooo hawt. Dries Buytaert 10:15 00:45 H.1302 drupal_performance Drupal Podium English As many already know by now, 80 to 90% of the response time of a web page is dependent on the page loading performance (the fetching of the HTML and all files referenced). This is different from the page rendering performance, which is just the time it takes to generate the HTML. Drupal already tackles several issues pretty well. But there's more we can do! You can solve several additional problems today, just by installing extra modules (such as [http://drupal.org/project/sf_cache Support file Cache]), by configuring Apache (e.g. gzipped output), or by configuring some shell scripts (e.g. to optimize image files). I'll explain you how to apply these solutions. For most Drupal sites, CDN integration and putting JS at the bottom of the page have the biggest impact. However, these two techniques are currently very hard to apply properly to Drupal: both require hacks to Drupal core. My aim is to solve both of these problems as part of my bachelor thesis. I'll explain how I expect to solve this and the impact of both issues on your site. Wim Leers 11:00 00:45 H.1302 drupal_community_website Drupal Podium English Jobcircle is a community website for young employed people where knowledge and experiences are being shared, funded by the Dutch trader union 'FNV Bondgenoten'. It is a joint talk by developer and customer where the project goal and history are evaluated by the customer and where Niels goes more in-depth on the technical architecture and experiences. Niels van Mourik 11:45 00:45 H.1302 drupal_multi_site Drupal Podium English Tired of handing out FTP accounts for Web site hosting? Get a little queasy whenever someone asks about Front Page extensions? Drupal to the rescue! By using Drupal's multi-site install you can use a single code base to power all of your customers' Web sites. Installing a single code base will also make tech support and security updates a whole lot easier. In this session you will learn how to install Drupal, where to put modules and themes so they show up in the right places, and how ensure your customers have the right amount of control over their own domain. Emma will use real world examples from her own business network to reveal how Drupal can convert even the smallest clients to pots of gold. Emma Jane Hogbin 13:00 01:00 H.1302 drupal_import_manager Drupal Podium English Continuously importing data, of any size or number of sources, needs infrastructure. Neil Drumm wrote [http://drupal.org/project/job_queue Job Queue] and [http://drupal.org/project/import_manager Import Manager] to queue and manage imports. He will show how to use these modules to get the basics out of the way. Neil Drumm will also talk about a few strategies he found successful for data conversion. The presentation will not be able to cover how to get everything into nodes, but will teach how to think about converting data. At [http://maplight.org/ MAPLight], Neil managed importing data from GovTrack, OpenSecrets, the FEC, the Iowa Legislature and other government entities. Some updates happen within 30 minutes of an action in Congress, while others need to be run monthly, or reports as-needed. Neil Drumm 14:00 00:45 H.1302 drupal_staging_to_live Drupal Podium English Roel explains how he manages deployments of very large Drupal sites from staging to live servers. The problem: A client has a live site with 1000's of pages, 10's of blocks containing rather static information. There is almost no user interaction except for a few webforms to collect some user information (contact, request for documentation, etc..) While the site is live, the client wish to prepare for the next iteration of the website. The new version will contain altered, new and deleted nodes and blocks. There is a workflow to allow approving all the changes by the end-redaction. While the old site is unaltered they wish to have a live-preview of what the new website will look like. a Solution? Can Drupal handle this out-of-the-box? An initial guess would be to define a some states using the workflow module and handle revisions using the revision_deletion and revision_moderation modules. But that doesn't help when you want to test drive the site as anonymous visitor. How DID we do it? A small set of bash scripts and drupal modules did the trick. We'd be honoured to explain those and be cross-fired with questions! Roel de Meester 14:45 00:45 H.1302 drupal_showcase_flanders Drupal Podium English Davy explains how they implement a complex Drupal website at DotProjects. DotProjects is developing a new website for Cultuurnet Vlaanderen. This website allows users to browse all kinds of events happening in Belgium. All event data is not managed in Drupal but is managed in Cultuurnet's own system and access to this data is provided by their REST API. This event data, which is "hosted" on their API is enriched with comments, ratings, YouTube video's, Press releases, ... in Drupal. To make this possible, all events need to exist in Drupal as nodes. For this we developed an offline synchronisation method and a real time synchronisation method where nodes for events are only created as soon as their node page is accessed. For each event the system also tries to look for a YouTube video, Flickr image, Wikipedia entry. This all happens automatically without any user interaction. For this a custom Drupal module was developed (Service Attachments) which allows to automatically look for content on APIs for each node. With a high focus on these two problems, we'll explain the process of implementing this website in Drupal. Frederik Van Outryve Davy Van Den Bremt 15:30 00:45 H.1302 drupal_automated_translation Drupal Podium English A non-technical presentation on how to automate the web translation process with Drupal. Many organizations operating across the borders are reluctant to localize their (Drupal) web site content because of cost and time constraints. They are aware though that, just as print marketing, e-marketing also needs to use the business language of the local markets in order to be successful. Find out about how you can automate the web translation process and dramatically cut budget and deadlines, with the AWTW module for Drupal (available in the Drupal community for about a year now). And see how large organisations have been making use of this efficient solution. This presentation will be non-technical and given by a non-developer. Stany van Gelder 16:15 00:45 H.1302 drupal_taxonomy Drupal Podium English Taxonomy is Drupal's classification system. In this talk Bart explains how it differs from a regular categorisation system and what Drupal core and contributed modules offer to manipulate, browse and apply it. This talk gives a short explanation about what Taxonomy is and what it does in simple and clear terminology. Bart briefly describes the history of Taxonomy from Drupal 4 to Drupal 7. Finally he discusses when to use Book.module and when Taxonomy for arranging your content. Bart Feenstra 09:00 00:45 H.1308 moz_seamonkey Mozilla Podium English SeaMonkey 2 and the vision beyond.

Philipp Kewisch http://www.mozilla.org/projects/calendar/sunbird/ 12:00 01:00 H.1308 moz_thunderbird Mozilla Podium English After several years of hibernation, [http://www.mozilla.com/en-US/thunderbird/ Thunderbird] development has ramped up again in the last year especially. This talk is intended to give open source hackers an update on where Thunderbird is in its runup to the Thunderbird 3 release, what new systems are available for add-on developers, and how to get involved if you want to help fix email. In the first part, David Ascher, one of the drivers of Thunderbird 3, will give an overview of the important changes that have either already landed, or are in various stages of development. These include: * a whole slew of platform-level updates which fall out of the Gecko platform development. * a new SQLite & JavaScript-powered database of all of your emails, which lets you build powerful new ways of reading & processing mail * a set of optimizations that make the day-to-day interactions with Thunderbird much faster, thanks to moving blocking operations to background threads * new views on email, including google-style search results, conversation views, canvas-based visualizations, and more. In the second part Ludovic Hirlimann, QA lead for Thunderbird, will explain how you can involve yourself into fixing email: * Joining the QA effort - where bugs need to be reported, triaged, tests written and run. * Joining our marketing effort and help the rebirth of thunderbird ([http://www.spreadthunderbird.com/ spreadthunderbird]) * Proposing patches and helping the development team. * Translating thunderbird: how to help make Thunderbird rock in your language. * Developing extensions to build the tb ecosystem.

Helge Bahmann 12:00 01:00 H.1309 xorg_power_mgmt X.org Podium English Computers spend a lot of time idle, and graphics cards spend a lot of time just displaying a static image. This talk presents various techniques for reducing the power consumption of graphics hardware without any significant impact on visual quality or performance. Matthew Garrett 14:00 01:00 H.1309 xorg_r600_demo X.org Podium English By allowing the release of r600_demo AMD has carried out a first step of their promise to release enough information for open source DRI driver development. As the initial, to be released documentation will be very register centric there is hardly enough information about how the chips are actually working. This talk will give an overview over how the r6xx and r7xx chip families are to be programmed, and in which pit falls one might stumble. Matthias Hopf 15:00 01:00 H.1309 xorg_llvm_gallium X.org Podium English With the increasing importance of shaders, it has become necessary to use advanced optimization strategies for shader compilers.

We will discuss the main difficulties behind this work, the inner workings and the current developments. Stéphane Marchesin 16:00 01:00 H.1309 xorg_shader_opt X.org Podium English Different GPUs have different architectures and thus require different shader compiler optimisations for more optimal performance. This talk explains some of the differences between both AMD, Nvidia and Intel GPUs and will present some compiler algorithms to optimise shaders accordingly. Jerome Glisse 10:00 01:00 H.2213 centos_intro Fedora+CentOS Podium English The reasons why you need an enterprise Linux distro. What is the CentOS project ? From where is it coming and where is it going ? Wanted to be involved ? What's cooking actually in the CentOS kitchen ? Let's have an interactive talk about that (and more). Fabian Arrotin 11:00 01:00 H.2213 centos_el_landscape Fedora+CentOS Podium English Dag Wieers 12:00 00:30 H.2213 centos_desktop Fedora+CentOS Podium English Why CentOS is a preferred choice on the desktops in the enterprise or even at home. Toshaan Bharvani 12:30 00:30 H.2213 centos_san Fedora+CentOS Podium English How to boot from an iSCSI LUN. CentOS can be installed onto an iSCSI LUN and you can boot from it if your hardware supports it. Usually that means you need an iSCSI HBA or at least some fancy Firmware extensions. However, it can also be done on standard-hardware by exploiting PXE. Andreas Rogge http://etherboot.org/ 13:00 01:00 H.2213 centos_selinux Fedora+CentOS Podium English drwxr-x--x is still the normal means of security under linux, giving access rights to data to users, groups and anyone else. This method isn't very flexible, so access rights are either given for larger groups of people or the administrator is tearing out his hair because he is lost in a maze of user, file and directory structures, which make working more than complex, but don't make the system more secure. Enter SELinux, a security infrastructure which is integrated into the kernel and promises to make securing your system more flexible. SELinux is a security framework which is included in the kernel of the Linux operating system. Under SELinux files don't only have the normal access rights or ACLs, but also have a context. You as a user or a program have to be able to use that context to get access - even if normal access rights would allow you to change the file. This talk gives a short overview of SELinux and talks about the tools in CentOS 5 (and Fedora) which enable you to change the behaviour of SELinux. In the second part we will secure a small daemon with the tools we learned about in part 1. Ralph Angenendt 14:00 01:00 H.2213 centos_ldap Fedora+CentOS Podium English How to support a huge number of users on a huge number of machines resulting in millions of user accounts. Geerd-Dietger Hoffmann 15:00 01:00 H.2213 fedora_cobbler_koan Fedora+CentOS Podium English Cobbler is a Linux installation server that allows for rapid setup of network installation environments. Most deployments of Linux systems are very rarely just one or two systems. Once you get past just installing Linux on your home system or your workstation it is time to think about how you are going to manage installing, and if required re-installing, these groups of systems in a repeatable manner. This is where Cobbler and Koan come in. Cobbler is a next generation systems management tool designed to keep a track of not just your systems but the initial system deployment configuration, host networking and even the configuration management. Koan provides the same facilities in the new world of systemvirtualization. During this talk we aim to demonstrate just how easy Cobbler and Koan make keeping track of your Linux deployments and configurations. Jasper Capel Robert Lazzurs Cobbler project 16:00 01:00 H.2213 fedora_freeipa Fedora+CentOS Podium English [http://www.freeipa.org/page/Main_Page FreeIPA] is an integrated security information management solution combining Linux (Fedora), Fedora Directory Server, MIT Kerberos, NTP, DNS.

This talk will give an introduction on how Wine works, what is possible and how it all works together, why it is not slower, why emulating only the runtime environment is to a distinct advantage compared to virtual machines. Marcus Meissner Wine website 12:00 00:45 H.2214 opensuse_mirrorbrain openSUSE Podium English The MirrorBrain, a.k.a. the openSUSE download redirector, automatically redirects clients (web browsers, download programs) to a mirror server near them. It works similar to the systems employed by sourceforge.net, mozilla.com or similar large organizations, which face a number of download requests which is too high to be practically handled by a single site. To find a mirror close to the client, the redirector "geolocates" the client by its IP address. If several mirrors are found to be suitable, the redirector load-balances requests to the mirrors based on their capabilities. Peter Poeml Mirrorbrain website 12:45 00:45 H.2214 opensuse_netbooks openSUSE Podium English Everybody loves Netbooks, so why don't use your favorite Linux distribution on it. The talks shows what the pitfalls and limitations are and how to get openSUSE working on Netbooks. Stefan Seyfried 13:30 00:45 H.2214 opensuse_yast2_future openSUSE Podium English On openSUSE 11.0, YaST came out with new features like a themable look and a robust & fast package manager. 11.1 came out with more robust solving and various minor features. In this talk we will present all the features that have high priority for the next openSUSE release and areas where we are doing research that will eventually be features in future versions. Duncan Mac-Vicar Prett 14:15 00:30 H.2214 opensuse_openfate openSUSE Podium English Every distribution have features beside the usual version updates of packages. How to decide which feature should be in the next version, which are doable in the usually short timeframe, where to focus the energy and time of the developers? openfate makes the process more easy to track and more transparent. Thomas Schmidt openFATE project page 14:45 00:45 H.2214 opensuse_arch_collab openSUSE Podium English This session will focus on the "Architecture of Collaboration" implemented in the [http://www.kablink.org/ Kablink Open Collaboration project].

Contrary to early websystems it does not make use of forum-threads (avoiding their many problems), but of tags and links that can also be added to articles by others than the original author. The talk will be on several topics; On LogiLogi.org, a webplatform for philosophers written in Rails and on the LogiLogi Foundation which thinks Web-Applications should be Free Software too, that is Affero GPLed, if Free Software is to have a future on the Brave New Web. That is we should think beyond Stallman's: one should not rely on another’s machine to “do calculations with ones data”. Also by the end of january we will have extracted and released some gems and Rails plugins, one for creating Spam-free forms without captchas (in this way http://nedbatchelder.com/text/stopbots.html) and yet another solution for the rounded corners problem (and scaling and resizing SVG back-ground images in general) using javascript and RMagick. We might at the end shortly demonstrate these too if the audience wishes. LogiLogi is a fully RESTfull Rails-app, which is Free Software.

This session will introduce you to the software, show how it was developed with flexibility and extensibility in mind and how easy it is to adapt it to your own needs. Raphaël Bauduin Dedomenon MyOwnDB 12:00 00:30 AW1.120 ror_wt_ruby Ruby and Rails Podium English The Wt toolkit allows programmers to develop web applications in C++. It abstracts away the details of coding in HTML, JavaScript and CSS so that the developer can just work with widgets in a similar manner to the Qt library for desktop applications. When Wt is combined with Ruby via the Wt::Ruby bindings, it offers a very different approach to the more traditional Rails or ASP style approach based on web pages, where program code is embedded into HTML. The talk will discuss how Wt::Ruby works, give an overview of the api and how it can be used with FastCGI in an Apache server. There are many interesting possibilities to combine Rails technology, such as ActiveRecord or the ActiveSupport Ruby extensions, with Wt::Ruby and the talk would hope to inspire people to start experimenting.  Richard Dale Wt::Ruby 13:30 00:45 AW1.120 ror_objects Ruby and Rails Podium English This presentation delves into Ruby's object model. Ruby's object model is class-based, so we cannot discuss objects without including classes. Next we discuss bindings and scoping in Ruby, which are somewhat related but still two different concepts. This presentation intends to go beyond the knowledge of the average Rubyist and aims to teach you more about the intricate details of how Ruby works and how you can exploit these to your advantage, even if just to wow (TM) your coworkers. Peter Vanbroekhoven 14:15 00:30 AW1.120 ror_sinatra Ruby and Rails Podium English [http://sinatra.rubyforge.org/ Sinatra] is a Domain Specific Language(DSL) for quickly creating web-applications in ruby. It keeps a minimal feature set, leaving the developer to use the tools that best suit them and their application. With Sinatra you can build a web application in a single file, which makes it fun and easy to use. Koen Van der Auwera Sinatra 14:45 00:30 AW1.120 ror_ruby_and_java Ruby and Rails Podium English Ruby is quite often presented as the Java successor. This is a highly controversial purpose. However, when you start a new project it can be important to know what are the advantages of these two great languages. In this talk, we will present their differences. Java is a well-established and well-known language. In opposite, Ruby is a rising star which is not mastered by everybody yet. When you start to develop a new project you have to make a language choice. It is not always easy to choose between learning an exciting new language or relying on a popular highly-used one. In this talk, I will discuss the pros and cons of Ruby and Java, what are the best trade-offs for your application and what are the performance differences. I will show that it is not that complicated to learn Ruby coming from Java. From a business point of view, I will also explain why a good language choice can help you saving money. Here is a brief talk summary : * Ruby vs. Java syntax * Interpreted or compiled languages * Dynamic typing * Metaprogramation * Language related philosophies * Performance comparison We will also have a quick peek at JRuby, the Ruby interpreter build upon JVM.

Probably the biggest new feature of Rails 2.2, released in November 2008, is its integrated internationalization framework, which ends a complicated past of many incompatible solutions based on various gems and plugins. This talk will discuss the various following topics: * a brief recap of the history of i18n in rails * an explanation what the new framework does: ** the API and its implementations ** translation files ** namespaces ** interpolation and pluralization * a small demo of how to use the framework * a presentation of plugins available to extend the framework * a list of valuable external resources Nicolas Jacobeus http://rails-i18n.org/ 16:15 00:45 AW1.120 ror_hosting Ruby and Rails Podium English Real-life experiences in designing, engineering and supporting hosting environments.

Terrence Barr 11:45 00:30 AW1.125 java_grails_netbeans Free Java Podium English This short talk should give Java/NetBeans developers an overview about how the [http://wiki.netbeans.org/Groovy Groovy and Grails support in NetBeans] works under the hood. Matthias Schmidt 12:15 00:30 AW1.125 java_universal_vm Free Java Podium English The Java Virtual Machine is often assumed to be tied to the Java programming language, but the success of Groovy, JRuby, and Jython shows there is more to the JVM than meets the eye. This talk will look at aspects of the design of the JVM that make it suitable (or not) for non-Java languages, and explains how JSR 292 is designing new abstractions that can help the implementation of all languages. These include the "invokedynamic" instruction, interface injection, and lightweight methods. Ultimately, they might enable non-Java languages to run even faster on the JVM than Java itself. Alex Buckley 12:45 00:30 AW1.125 java_jsr292_dynamic_lang Free Java Podium English JSR292 introduces VM supports that ease the implementation of dynamic languages on Java VM. This talk will present the different parts of the spec (knowing that is a work in progress) and some details/strategies of the implementation of the JSR292 specification in hotspot. Remi Forax 14:00 00:15 AW1.125 java_jamvm Free Java Podium English Over the past year JamVM has been reworked to make it smaller, faster and more reliable.

Levente Sántha http://www.jnode.org/ 15:15 00:15 AW1.125 java_zero_shark Free Java Podium English OpenJDK only supports three processors, x86, x86-64 and SPARC, but Linux distributions typically support many more. Zero is an interpreter-only port of OpenJDK that uses no assembler and therefore can trivially be built on any Linux system. This talk will be about developments since the last FOSDEM. The build system has been improved to the point that building is as simple as "./configure && make"; many new platforms have been tried and tested; and a platform-independent JIT called Shark has been developed that uses the LLVM compiler infrastructure to JIT compile Java methods without introducing system-specific code. Gary Benson 15:45 00:15 AW1.125 java_recruiting_foss Free Java Podium English The talk will focus on experiences gathered during my time as the Gentoo Recruiters lead. The aim is to share how we at the Gentoo Java project have succeeded or not in getting new people involved. Petteri Räty http://www.gentoo.org/proj/en/devrel/recruiters/ http://www.gentoo.org/proj/en/java/ 16:00 00:30 AW1.125 java_openjdk_community Free Java Podium English An open discussion to chat about the current OpenJDK environment: technical, infrastructure, governance, transparency, contributions, policies, etc. We all know there's still a lot of work to do, so the focus shouldn't be on gripes, but hopefully we can identify the top priorities and some easy-to-accomplish things that will have a big impact on community growth and contentment. Dalibor Topic 16:30 00:30 AW1.125 java_pure_gpl Free Java Podium English Many successful open source projects use pure GPL - true to the ideal of free software - requiring everyone to contribute under the same, open terms. But as open source increasingly becomes a foundation for core functionality used both in non-commercial as well as commercial ways the call for more liberal licenses is getting louder. GPL with classpath exception, LGPL, BSD, Apache, Eclipse, and others allow adopters to build upon the open source code in proprietary ways - violating the true spirit of free software but giving developers more freedoms to chose the best approach for their project or product. This session aims to be a free-flowing discussion on the question whether pure GPL without any exceptions is still up to date with the changes occurring the software industry. Terrence Barr 09:00 01:00 AW1.126 mysql_pbxt_storage MySQL Podium English PBXT is an ACID-compliant storage engine for MySQL available for MySQL 5.1 and 6.0. PBXT is also available for Drizzle and is shipped as part of the OurDelta builds for MySQL. PBXT is reaching GA state and now its a good time to learn how you as a DBA can benefit from this. During this session, attendees will learn about the best PBXT practices, including PBXT deployment architectures on various types of media, PBXT multicore performance, system variables and their tuning, startup parameters and run-time statistics. The session will also cover other practically important topics such as installation, compatibility with other storage engines, migration, monitoring, recovery of corrupted data, online backup. Vladimir Kolesnikov 10:00 01:00 AW1.126 mysql_monitoring MySQL Podium English Over the past 18 months different open source monitoring solutions have popped up, some of them with a lot of potential. Zabbix, Zenoss and Hyperic are probably the most famous ones but other more specialized ones exist. Last year we evaluated these Monitoring solutions and presented our findings at OLS. As we are MySQL users we obviously wanted to take a closer look at these tools regarding their integration with MySQL. This talk therefore will guide the MySQL users around in a selection of Open Source Monitoring tools that they could use to monitor MySQL as a part of a bigger infrastructure. Kris Buytaert 11:00 00:45 AW1.126 mysql_cluster MySQL Podium English MySQL Cluster became a new product in 2008, but little is still known about it. This talk will show how MySQL Cluster works, and show some practical situations where it can be useful. Version 6.4, the next release, will also be presented with some great new features coming in. Geert Vanderkelen 11:45 01:00 AW1.126 mysql_plugins MySQL Podium English MySQL 5.1 features the plugin API. In essence, the MySQL plugin API provides a generic extension point to the MySQL server. It allows users to load a shared library into the server to extend its functionality. A key feature is that this process is completely dynamic - the server need not be re-compiled and need not be stopped in order to benefit from the functionality of a new plugin. Hence, new functionality can be added without suffering any downtime. This session provides an overview of the plugin architecture. The different plugin types will be described. Then, the process of creating your own plugins will be described. This will be illustrated with code examples. Roland Bouman 13:15 01:00 AW1.126 mysql_social_networks MySQL Podium English MySQL runs a large number of the social networks of today. LinkedIn, Facebook, Flickr, Dopplr, Doodle and many other social websites run on MySQL. It's a privilege for MySQL to be part of the fabric of tomorrow. However, MySQL is still not *using* these social networks in an optimal way. For his overview, Kaj has guinea-pig tested a number of social networks and shares his experiences, with a particular emphasis on what the social network in question can do for MySQL users, customers and employees. Kaj Arnö 14:15 00:45 AW1.126 mysql_xtradb_storage MySQL Podium English Percona builds binaries that contain recent versions of the MySQL database server, plus additional popular patches not included in the official binaries from MySQL/Sun. Some patches improve InnoDB performance under high loads. Others provide diagnostic tools useful to DBAs. The patches are authored by MySQL users like Google, Proven Scaling, Open Query, and Percona itself. This talk is a guide to why we do it, our current patches and our plans for the future. Additionally, this talk will cover the XtraDB storage engine, a recent project started by Percona. Ewen Fortune 15:00 01:00 AW1.126 mysql_partitions MySQL Podium English MySQL 5.1 introduces partitioning – a very useful feature for databases with large tables. This session explains the benefits of partitioning and shows in practice how to take advantage of its features. Topics include: * Benefits and limits of partitioning * Understanding the partitioning types (RANGE, LIST, HASH and KEY) * Partitioning pruning and EXPLAIN additions * Benchmarking partitions * How to partition by dates * Partitioning with MyISAM tables * Partitioning with InnoDB tables * Partitioning with Archive tables * Use cases * Partition maintenance: ** converting partitioned tables to normal ones; ** adding and dropping partitions ** reorganizing partitions ** checking and repairing partitions Giuseppe Maxia 16:00 01:00 AW1.126 mysql_sharding MySQL Podium English Database sharding is an approach to horizontally scale databases by federating data over different servers. The talk will give an overview of the different approaches we have had and still have at Netlog, and how we came to the current solution. Experiences, tips and remarks from having worked on the Netlog implementation of sharding with mySQL and PHP, in a high availability and high performance focused environment, will be shared in this session. Related technologies include memcached and the Sphinx search engine, that are being used to tackle some of sharding's difficulties.
