Projects I am associated with

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

Linear Tape File System (LTFS). I worked on the design and implementation of LTFS for single drives and large libraries. Along with my team, I received a surreal Emmy award for the way our work transformed the Media and Entertainment industry.
HDF5-UDF. User-defined functions for the HDF5 scientific file format. To show how cool this project is, I have ported the classic Doom game so it renders the game frames as dynamic HDF5 datasets.
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.
Runner. A container-free filesystem virtualization tool that runs on top of GoboLinux. We use it to multiplex the filesystem so that different programs have a different view of /usr.
DemuxFS. A live filesystem that aids on the analysis of transport streams in digital TV systems.

Past & fun projects

GP32. I bought a portable videogame console back in the day so I could port Linux to it. Here are the patches I produced along the way.
ARM-based laptop. Way before netbooks became a thing, I had a really good time with friends Marcelo Fonseca and Marcelo Miranda creating a prototype of an ARM-based laptop. The prototype shown in this picture was running GoboLinux.
TORCS. Had some fun modifying the TORCS car simulator so I could ride a motorcycle instead.
XLode. Used an accelerometer as input device to Hisham Muhammad's XLode game.
