About

This is Lucas' corner at GoboLinux.org. Here you will find some bits from current and past projects along with scientific publications of mine.
Should you have any questions, feel free to contact me. Thanks!

Personal

Name: Lucas Correia Villa Real
Geolocation: Sao Paulo/SP, Brazil
Occupation 1: Being a nice dad!
Occupation 2: Research Software Engineer @ IBM Research Brazil
Occupation 3: Passionate bicycle rider

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 a considerable amount 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 and a CD-ROM drive that works.
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.
