Oculus RIFT development
![]()
Virtual Reality headsets have been consistently disappointing for several decades. Three reasons come to mind in order to explain this state of things:
The hardware is expensive: The latest Sony HMZ-T1 is 799$.
The hardware is not good enough: The motion sensor, screen latency and screen limited Field of View are unable to provide a feeling of immersion.
The software is non-existent: No major studio has ever supported VR Headsets.

Doom3 Source Code Review
![]()
On November 23, 2011 id Software maintained the tradition and released the source code of their previous engine. This time is was the turn of idTech4 which powered Prey,
Quake 4 and of course Doom 3. Within hours the GitHub repository was forked more than 400 times and people started to look at the game internal mechanisms/port the engine on other platforms.
I also jumped on it and promptly completed the Mac OS X Intel version which John Carmack kindly advertised.

Cracking Kevin Mitnick's Ghost In Tthe Wires Paperback Edition
![]()
I received yesterday a copy of Ghost In The Wire Paperback edition. Kevin Mitnick seems to have updated all of the challenges found at the beginning of each chapters. Since they are all available on book.google.com preview I don't think it is a big deal to publish and discuss our solutions here.

Be A Donor

This is probably the proudest moment of my Computer Science career so far: On April 17th, 2012 the Government of Ontario released the Mobile Website I designed and implemented for the major part of 2011. Beadonor.ca allows you reinforce your decision to be an organ donor. I feel honored and privileged to have been able to contribute to such a noble cause.
Many people are unaware of it but to become an organ donor is all about making sure your relatives will follow your decision when we are gone. An organ donor card...and actually any piece of paper that you...
Android Shmup

Six months ago I released the source code of "SHMUP": a modest indie 3D shoot'em up designed for iOS. Since it did honorably on the Apple Appstore I offered anyone to port it to Android Appmarket for a 50/50 revenues split. Two developers consecutively took on the challenge only to give up a few weeks later.
So I downloaded the Native Development Kit from Google and I did it myself. I completed the port this weekend and even released a free version.
The codebase runs on Windows, iOS, MacOS X and Android in one click. Here it is.

Coming back from FOSDEM
After having skipped FOSDEM in 2011, I wanted to go this year, especially because of the Golden Delicious stand where we had the OpenPhoenux GTA04 on show. A lot of people came around and were excited that someone picked up where Openmoko had left in 2009. The GTA04 is the true successor of the FreeRunner and I strongly invite all of you to support this movement by buying one. You will not get a more open mobile phone anywhere else. I know that Brussels is always a bit colder than Frankfurt, so I tend to carry appropriate clothing... what I...
IT has seen a crazy year
Information Technology has seen a really crazy year. Among all the smaller incidents, the big bangs involved Nokia partnering with Microsoft, abandoning Maemo, HP driving with WebOS against the wall, patent lawsuits everywhere. What that means for FOSS-lovers is clear... you can't trust any company to continue working on anything. Business demands are what counts in the world of mass markets. If you want longterm support for a platform, your best bet is to build a community around it. But you will also want to work on hardware support otherwise you'll run into the next dead end. To be honest,...
Towards the end of 2011
Tempus fugit. I can tell you. Even more so, if you have a baby. I must confess I somewhat underestimated the impact the baby would have on my spare time. In some weird mindset I really thought I could continue working as usual on my open source projects... as we know now I couldn't. I completely lost track and have to catch up with all changes that happened over the last 6 months. The first bunch of weeks with the baby were really demanding. I mean, really. She screamed a lot and could only sleep in our arms. Boy, were...
Progressive playback: An atom story

I have been doing a lot of work with video containers recently, especially figuring out interoperability between iOS/Android and optimizing progressive playback. In particular it seems Android devices fail to perform progressive playback on certain files while iOS and VLC succeed:
Why ?
As usual understanding things to the deep down proved extremely worthy.
