I also got nothing to : say, listen, watch or hack.

I got my hands on a msp430 launchpad to play around with it, and unluckily, the launchpad does not play nice with MacOSX 10.6. After the break, you'll get my tutorial to make it work.

Je me suis depuis peu inscrit au statut auto-entrepreneur, et évidemment, j'ai vite eu besoin de sortir une facture. J'ai cherché sur le net, et ai trouvé deux blogs qui ont fait un système identique Tengu en suisse et Godefroy en France.
Bref, j'ai repris leur travail et l'ai adapté au besoin d'autoentrepreneurs (que des factures HT et la mention qui va bien), et fait quelques modifs comme notamment revenir à la font originelle qui est plus belle que la « bera » (quelle horreur), fait en sorte que la compilation se fasse à l'aide d'un simple "make" et d'avoir toutes les factures rangées, .tex/.pdf cote à cote.
Tout ça est sur mon github comme d'hab !

At Le Loop hackerspace, we often get broken, old or unwanted weird devices. Then recently we were given two Led Matrix displays with a technology from the 80s.
First one was a one line with red led display
and the second one was a green multiline display
So, here is a little story on how I managed to pwn them.

For a work's project I needed to use two magnetic card readers ; our usage was depending on which one is used and the card's ID.
So I sourced a magnetic card reader that outputs the Id through a TTL serial line and then I could manage using an arduino both serial lines and get them to work how we needed.
But what was my surprise to get USB HID readers once I receipt the package ! So I plug them in, and well, they worked out of the box... but both of them output Ids on the console the same way. We were on a rush on the project, so we had no time to send them back.

I just ended a proof of concept of door locking/unlocking system for our hackerspace.
Nothing extraordinary, all the doc and code are there :
Pictures are coming...

I just released today my Master's work done during my Internship at Bearstech. The code has been released under GPLv3 on :
The goal of that project is to build some kind of distributed middleware that stores and share data across different nodes (whatever they are) indexed by metadata. As the internship, and thus the length of that project was only 5 months, I had to make severe technological choices that made that code only a proof of concept, instead of really usable user-end code.
For instructions on installing and using it, please read the wiki page.

Back in high school, I had the luck to get some experience and learn many things about stage lightnings. But, as I was already computer-litterate at that time I was amazed to discover that at the ethernet era, the protocol used for controlling lights was still DMX-512 based on RS485 serial line over a 3 points XLR. Because the DMX network configuration is a daisy chain, it looked to me a lot like BNC-based 10 base-T computer networks... with cable length, line terminals... being one's worst nightmare.
At the same time, back in 2000-2002, it was the beginning of the WiFi-aera. That's why, I imagined we simply could encapsulate a DMX packet in TCP packets (or even a UDP datagram, as DMX is a broadcast-only protocol) sent over WiFi and receive them through a dongle attached at the back of the DMX-enabled projectors (and have Triac based system to control analogical projectors).

Luzern, 28th june, 2010 - A new round of negotiations of the anti-counterfeiting trade agreement (ACTA) is beginning today between 11 negotiating parties -including the EU- in Luzern, Switzerland. All around the world, organizations of concerned citizens, people living with HIV, and academics urge governments to renounce to this illegitimate agreement.

After years of working with an IRC client inside screen on my server to which I connect using SSH, I was missing having any kind of notifications when I'm being highlighted. I don't want to use bouncers or to disconnect/reconnect all the time. So I prefer to make a ssh tunnel from an IRSSI script to a python script I run on localhost, that sends every configured highlight to localhost. That other script calls libnotify on linux or growl on OSX to display the notification.
Source code available at : http://github.com/guyzmo/irssi-over-ssh-notifications
Contributions are opened to package and make it better.
There's a bug I still can't get rid of : when notifications are sent through the tunnel, SSH reports almost all the time :
setsockopt TCP_NODELAY: Invalid argument
if anyone has an idea on how to resolve that, drop me a mail !
