Hackers rules on Linux.
In his blog at IBM developerWorks (only in portuguese), Pablo Hess draws an interesting overview of how a free software development community behaves.Using as an example the recent and surprising change in the number of version of the Linux Kernel, one of the most important free software, we can understand the interaction in this process and most importantly, in my view, understand the hacker spirit, which transcends even the influence of sponsorship of major corporations.

Distributed processing with Boinc.
Distributed processing is one of the coolest concepts in computing. Consists in divide the work among multiples nodes (computers) so each one process your job and returns the result.This concept is applied in many areas of computing (such as Internet services) but a way to see this in pratice is through the software Boinc (Berkeley Open Infrastructure for Network Computing).
This software being installed on your computer use idle cycles of the machine (processor and memory) to process information from scientific research projects in areas such as astrophysics, cosmology, medicine and many others. It's a cool thing to do if you usually leave your computer idle for hours.
I remember in 2000 my father had on his computer the SETI@home, this project searchs for intelligent life in space. Who has read the book or seen the movie Contact (Carl Sagan), knows what it's about.
To participate of the distributed processing donating a little of your computer is simple. The software is available for multiple plataforms (Linux, FreeBSD, Windows, Mac). Just download, install, then visit the site of one project that you want to participate, create your account and finally attach this project in the software.
Here are the sites of some projects:
Cosmology@Home
Einstein@Home
SETI@Home
