Dr Jekyll & Mr Hyde

As an experienced programmer, I participate in many Free Software projects when time permits. I am committed to a few projects, and I frequently submit patches to random projects that I happen to bump into. I also understand the dynamics of free software: when a bug stands in my way, I often fix it myself […]

I was watching an Alias episode when I saw Jennifer Garner set a bomb clock to 4 minutes. At that time, I thought about my rforth1 compiler and realized that the code that writes a constant value into a timer register was probably doing things in the wrong order regarding the PIC timers internal latches.
It […]

My device driver for the watchdog embedded in the Winbond 83697HF/HG SuperIO controller has been integrated into the forthcoming Linux 2.6.19 kernel. If you want to use it on a Dedibox dedicated server, you have to:

activate the option CONFIG_W83697HF_WDT in your kernel configuration file
load the module at boot time with parameter wdt_io=0×4e; creating /etc/modules.d/wdt with […]

I worked a lot on rforth1 lately, a Forth compiler targetting the PIC 18f family of microcontrollers. I have added many new optimizations in order to generate smaller and more efficient code.
Let’s take an example. The Forth code below cycles through the 8 possible states of 3 leds connected to ports B5, B6 and B7 […]

In my job, I often participate to multi-partners projects which get public (European or national) funding. In those projects, we are required to produce deliverables that show the progress of our work.
The final deliverable is edited by an editor (how surprising) who is in charge of coordinating inputs from various partners and make them consistent. […]

I just setup a page explaining what works under Gentoo GNU/Linux on the Fujitsu-Siemens Lifebook S7110 laptop. Please let comments here for questions, remarks or enhancements.

I have a friend who knew nothing about Free Software three years ago. When she acquired a laptop, Microsoft Windows came with it, and she used it. After some time, it became slower and slower and felt very slugish, at a point where watching DVDs on it was as pleasant as looking at the TV […]

As a member of the Areabot association, I participated to the 2006 French robotics competition last week. We had to develop specific software for our robot, driven by two Shix boards containing each one a SH7750R processor at 240MHz running Linux and a Stratix EP1S25 FPGA.
We decided to use Mercurial from the beginning for our […]

For the 2006 French robotics cup, I wrote two utility packages for GNAT, the GNU Ada compiler:

areadline: access the readline library from Ada;
aforth: embeddable Forth interpreter written in Ada (uses the areadline library).

I haven’t put a license file in them yet, but you can get them under the GNU General Public License version 2.

Comme je l’avais expliqué dans Asterisk - build your own PBX, la prise téléphonique de ma Freebox était connectée à mon PC par une interface analogique de type FXO. Sur le PC, qui tourne sous GNU/Linux, l’autocommutateur libre Asterisk gère mes communications et mes services. Tout fonctionnait correctement, même si la reconnaissance du raccroché du […]
