Talks
Welcome to the Alt-OS devroom
Start: 9h00
Duration: 15min
Speaker: François Revol
Presentation of the Rosetta OS Project
Start: 9h00
Duration: 15min
Speaker: François Revol
The Rosetta OS project is a collaboration by numerous embedded, BSD, and other operating systems to build an OS-independent driver API.
It aims at helping projects in sharing source code and drivers for better hardware support.

Introduction to RTEMS: A Real-Time OS for Embedded Applications
Speaker: Thomas Doerfler
Duration: 30 minutes
This session gives an overview over the RTEMS project, its distinct features, goals, typical applications and current capabilities. It sketches general requirements for real-time applications, basic RTEMS features, the structural differences between a Linux based and an RTEMS based application, available APIs, available subsystems and the driver models.
The goal of this session is to emphasis the distinct requirements addressed in RTEMS compared to UNIX-like Operating Systems. This should be a good base for further discussions on collaboration with other projects.

Introduction to Haiku
Speaker: Olivier Coursière
Haiku is a new open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.
A short introduction to the operating system will be presented, along with a little demonstration.

Why is Anyone Still Working on the GNU Hurd?
Speaker: Olaf Buddenhagen
Hurd having been in development for so long, but still not production-ready; and with Linux as a mature free kernel being firmly established as the de-facto standard kernel for the GNU system -- people often wonder: why haven't developers abandoned the Hurd long ago?
Without going into technical details, this short talk tries to explain the main idea behind the Hurd architecture, which sets it apart from other systems.

Network virtualisation using Crossbow technology
Speaker: Uros Nedic
Duration: 45min
Leveraging current hardware capacities becomes one ofthe mayor topics in current IT business. Designing toolsfor deploying network virtualization and effectivelycontrolling virtual network environments from the perspectiveof network capacities raised demand for a project called Crossbow. With this technology we could effectively control how anapplication access to the network and decide how much bandwidthit could use. Also, we could dynamically allocate bandwidthresources giving to the application surplus if needed on behalfof other(s) application(s) whose network resources are underutilized. This is done by creating Virtual Network Interface Cards (VNICs)and dedicating each of them to the different application we want todeploy. In this presentation we'll show how Crossbow technology workin practice deployed on OpenSolaris.

Update on Gallium3D ports to AROS and Haiku
Speaker: François Revol
Duration: 15min
Gallium3D is a new architecture for building 3D graphics drivers. Initially supporting Mesa and Linux graphics drivers, Gallium3D is designed to allow portability to all major operating systems and graphics interfaces.
We will be showing a quick demo of the recent progress of the Gallium3D ports to AROS and Haiku.

Porting challenge: Flashrom, the universal flash tool
Speaker: Carl-Daniel Hailfinger
Duration: 15min
Flashrom is the open source utility of choice to read and write flash chips and a real porting challenge because it needs full hardware access from userspace. Some say that only X.org needs a similar level of hardware access. Flashrom is working under Linux, *BSD, OpenSolaris, Mac OS X and Windows (somewhat) and people use it to reflash BIOSes, graphics/network/SATA cards, a game console and to control a boatload of external flash programmers. This talk gives a short overview of flashrom and its architecture, and then goes into detail about the work needed to port it to your favourite OS.
Porting KGI graphics drivers from Linux to GNU Hurd
Speaker: Olaf Buddenhagen
Type: Talk, possibly with small demonstration
Duration: 30 Min
Abstract:
GGI/KGI is a graphics driver framework, offering a clear seperation between actual hardware access and abstraction. The hardware access part was originally a kernel driver for monolithic UNIX kernels like Linux and FreeBSD. This talk is about porting that framework, to work with the hardware access part running as a userspace server process on top of the multiserver microkernel system GNU Hurd.
After a short introduction to GGI/KGI and Hurd architecture, this talk will dwell a bit on the interesting aspects of porting the kernel driver to run as a userspace process instead.

DDE - Generic Porting of Device Drivers
Speaker: Dirk Vogt
Duration: 30 minutes
This talk will give a short presentation of the Device Driver Environment (DDE), a library that helps porting Linux and FreeBSD device drivers to other operating systems.
The DDE is divided into two parts, the DDEkit, a generic operating system abstraction layer, and guest-specific DDE's (currently available for Linux 2.6 and FreeBSD) allowing to run unmodified Linux and FreeBSD device drivers. Currently there exist implementations for TUD:OS, an L4 microkernel based operating system developed at TU Dresden and the Genode operating system framework developed by Genode Labs (Dresden). There are also plans to port the DDE to Minix 3.

OpenSound System v4 port to Haiku
Speaker: François Revol
Duration: 30min
Open Sound System (OSS) is the first attempt in unifying the digital audio architecture for UNIX. OSS is a set of device drivers that provide a uniform API across all the major UNIX architectures, released under BSD/GPL licences.
The talk will describe the required steps for the port of OpenSound System v4 to the Haiku operating system.

Generating Driver Source Code with Rathaxes
Speaker: TBA
Duration: 30min
The project aims at generating driver source code for multiple Operating Systems from a single description.

Hands-on development with Haiku
Speaker: François Revol
Duration: 30min
Using pre-built Haiku images for virtual machines (QEMU/VirtualBox/VMware), we will be helping you build your first native Haiku application, and explore some of its unique features.

Haiku has No Future (like most other small OSS Operating Systems)
Speaker: Niels Sascha Reedijk
Many Open Source projects start as small but ambitious endeavors, with the hopes of becoming successful. Though it is fair to say that most do not. By taking some recent examples of successful OSS projects and putting it in a juxtaposition with contemporary queer theory (after all, being alternative is all about being queer), I attempt to construct a new definition of success that hopefully serves as an inspiration for OSS projects.

Extended File Attributes, how can we keep them around?
Speaker: François Revol
Duration: 15min
This talk will try to expose the need for an interoperability scheme for extended file attributes (aka xattrs), which are used by many FOSS OSes, each with their own format and semantics.
