Projects I am involved with

You will find a complete list of projects I have authored on my page at GitHub. These are my favorite ones:

DemuxFS. A live filesystem that aids on the analysis of transport streams in digital TV systems.
GoboLinux. A Linux-based distribution that redefines the file system hierarchy. I have been a core member of this project since its early days and continue to dedicate a considerable amount of time to it.
LTFS. A filesystem for LTO tapes starting with LTO-5. I worked on the design and implementation of LTFS for single drives and large libraries.

Random hacks (old stuff)

GP32. Porting Linux to the GP32 handheld.
TORCS. Adding a bike to the TORCS simulator.
XLode. Using an accelerometer as input to Hisham Muhammad's XLode game.
