To speed up the processing of these videos, we contracted Jan Gerber, the developer of ffmpeg2theora, to add denoising support to this tool. Thanks to this contribution, it is now possible for anyone in the community to directly denoise DV camcorder input and generate Ogg/Theora video in just 1 step. Before it was necessary to use mencoder‘s denoising filter, and because mencoder couldn’t process DV input properly, a preprocessing stage with ffmpeg was also required. This new functionality can also improve the quality and compression rate of live Ogg/Theora video broadcasts.
Learning how to write USB device drivers for Linux
Bootlin is proud to release a new set of training slides from its embedded Linux training materials. These new ones cover writing USB device drivers for Linux.
Like everything we create, these new materials are released to the user and developer community under a free license. They can be freely downloaded, copied, distributed or even modified according to the terms of the Creative Commons Attribution-ShareAlike 2.5 license.
Best wishes for 2007!
Bootlin is happy to send its best wishes to the entire Free Software and Open Source user and developer community. Whether you believe or not in Finnish Astrology, let 2007 be the Year of the Penguin! For our customers, we also wish that their competitors continue to use proprietary operating systems!
Do not hesitate to reuse our New Year’s card for your own needs. It’s Free as in Free Speech!

Embedded Linux contributions to the Linux Ecology HOWTO.
Bootlin has contributed major updates to the Linux Ecology HOWTO, a Linux Documentation Project document that gathers ideas and techniques for using Linux in an environmentally friendly way.
In particular, Bootlin took advantage of its experience with embedded Linux system development to add new techniques which can reduce power consumption or make it possible to extend the lifetime of old systems with limited resources.
Bootlin also contributed an overview presentation on this HOWTO. The latest HOWTO version with our updates (waiting for the next official release) can also be found on the same page.

Penguin New Year wishes and good reasons for using Free Software in 2006
Bootlin wishes a Happy New Year to embedded system developers and to all members of the Free Software and Open Source community.
Unlike other birds…
Penguins never freeze!
While most others stay locked in a cozy shelter…
with a penguin,
you can reach out,
withstand extreme conditions,
and pioneer an exciting world of opportunities!
Happy New Year!

- Source (Scalable Vector Graphics, created with Inkscape) and generated files can be found here. Rooster, hen and penguin graphics come from the Open Clip Art project.
- Contributed 3 reusable graphics (cottage, Christmas hat and pine tree) back to Open Clip Art.
To make these wishes come true, Bootlin has also released a new presentation collecting the main strengths (and weaknesses too) of Free Software in embedded systems. It should help to make the decision to (or not to) rely on penguins in 2006 and in the years to come.
A summary of the improvements brought in 1 year to our free embedded linux training materials.
Since our first public release in October 2004, we made significant improvements to our free embedded Linux training materials:
- The total number of slides increased from approximately 500 to more than 1000. Here are all available training materials and presentations.
- New training materials: audio in embedded Linux systems, multimedia in embedded Linux systems.
- New presentations: embedded Linux From Scratch… in 40 minutes, Linux on TI OMAP processors, free software development tools.
- Added many sections, updates and improvements to our main document: embedded Linux kernel and driver development. If you haven’t checked it for 1 year, you will hardly recognize it!
- Some of training labs now use the SkyEye emulator, which supports several arm boards. People can now practise with cross-compiling and booting the Linux kernel without having to purchase expensive development boards.
- KernelKit, a live GNU/Linux distribution derived from Knoppix, was created for embedded systems and kernel developers. In particular, it includes uClibc cross-compiling toolchains for several platforms: arm, armeb, i386, m68k, mips, mipsel, ppc and sh4. KernelKit is used in our training labs.
- The PDF versions of the documents now include internal and external hyperlinks, thanks to using OpenOffice.org 2.0. To navigate within the documents or to go to an external site, just click on the links in your favorite PDF reader.
- Some utilities were created and shared with the community: clink (to compact cross-compiling toolchains), and cOOol (to report broken hyperlinks in OpenOffice.org documents).
- The training materials were used for 12 training sessions delivered to embedded system companies and key silicon vendors.
- The documents are now released under the terms of the Creative Commons Attribution – ShareAlike 2.0 license, instead of the GNU Free Documentation License.
- Some of the documents have been translated to French, German or Italian by several contributors.
Your corrections, suggestions, contributions and translations are welcome!
I participated to the 2005 edition of the Ottawa Linux Symposium, but because of lost luggage, I only managed to shot one video, corresponding to the only one camcorder battery that I had left:
- TWIN: An Even Smaller Window System For Even Smaller Devices, by Keith Packard:
video (50 minutes, 307 MB)
New presentation from Bootlin
This new presentation has just been shown in the Libre Software Meeting event in Dijon, France.
It shows how to build a minimalist embedded system with a web interface from the ground up within 40 minutes.
