DIY: Home UBUNTU NAS Server

Back in 2003, I used to connect my computer on the my old 32′ TV, those huge and heavy TVs, to watch stuff from the internet, at that time, eMule was ruling the p2p community (can’t talk about USENET right? :} ). Then in 2008 I decided to build a better HTPC (Home Theater PC), a full dedicated computer connected to my TV, with good MotherBoard/VGA/SoundBoard, well, a good computer, with gaming capacities.

FeedTree: RSS via P2P

FeedTree is a P2P java app that uses distributed bandwidth to push RSS feed content to users faster than traditional newsreaders that poll their feeds on a schedule.
