Should you have any questions, feel free to contact me. Thanks!

Personal

Name: Lucas Correia Villa Real
Geolocation: Sao Paulo/SP, Brazil
Occupation 1: Research Software Engineer @ IBM Research Brazil
Occupation 2: Passionate bicycle racer

Projects I am involved with

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 considerable amounts of time to it.
Lazy. A console-based CD-player for UNIX and GNU/Linux operating systems with support for FreeDB. Useful if you still have audio CDs around, a working CD-ROM drive and no broadband connection to stream music from the Internet.
LTFS. A file system for LTO tapes starting with LTO-5. I worked on the implementation of the foundations of LTFS for single-drive and large libraries. Nowadays my interest lies on the LTFS I/O scheduler layer.

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.
