I have very strong C/C++/Tcl/Tk/Java/ASM knowledge..
I've been using Linux for 8 years now and I've always liked to use terminals for everything, so i'm used to command line stuff...
I run E17 as a WM, and I usually have around 50+ xterms running constantly.. I must have used a GUI for browsing my files twice in my entire life
I'm known in the open source world as KaKaRoTo, I'm the lead developer and project manager of the aMSN Project (http://amsn-project.net - an MSN Messenger clone) for which I've done quite a lot of stuff, mainly reverse engineering both the protocols and disassembled code.
Amongst other things, I wrote the libsiren library (SIREN audio codec).. it was an ASM to C reverse engineering of Microsoft's proprietary audio codec.
I work for Collabora (Open Source centric company), so I've been working with gstreamer, farsight and telepathy, and I'm the maintainer of libnice (first open source library implementing the ICE specifications) which is a NAT traversal library (GUADEC talk slides : http://people.collabora.co.uk/~kakaroto/libnice-talk-gcds2009.pdf ).
Pretty much all my code is open source and available if you know how to use google...
Oh, I graduated from Polytechnique Montreal as a Software Engineer... I think that's pretty much it
