Researchers Decentralize BitTorrent 262

Posted by CmdrTaco on Tuesday October 28, 2008 @02:01PM from the only-a-matter-of-time dept.

A Cow writes "The Tribler BitTorrent client, a project run by researchers from several European universities and Harvard, is the first to incorporate decentralized search capabilities. With Tribler, users can now find .torrent files that are hosted among other peers, instead of on a centralized site such as The Pirate Bay or Mininova. The Tribler developers have found a way to make their client work without having to rely on BitTorrent sites. Although others have tried to come up with similar solutions, such as the Cubit plugin for Vuze, Tribler is the first to understand that with decentralized BitTorrent search, there also has to be a way to moderate these decentralized torrents in order to avoid a flood of spam."

Why RAID 5 Stops Working In 2009 803

Posted by kdawson on Tuesday October 21, 2008 @07:03PM from the back-'em-up-rawhide dept.

Lally Singh recommends a ZDNet piece predicting the imminent demise of RAID 5, noting that increasing storage and non-decreasing probability of disk failure will collide in a year or so. This reader adds, "Apparently, RAID 6 isn't far behind. I'll keep the ZFS plug short. Go ZFS. There, that was it." "Disk drive capacities double every 18-24 months. We have 1 TB drives now, and in 2009 we'll have 2 TB drives. With a 7-drive RAID 5 disk failure, you'll have 6 remaining 2 TB drives. As the RAID controller is busily reading through those 6 disks to reconstruct the data from the failed drive, it is almost certain it will see an [unrecoverable read error]. So the read fails ... The message 'we can't read this RAID volume' travels up the chain of command until an error message is presented on the screen. 12 TB of your carefully protected — you thought! — data is gone. Oh, you didn't back it up to tape? Bummer!"

I'll plug my own open-source project for this:
Browse-by-Query-- it won't help with C/C++(sorry for the original questioner), but it will handle Java or C#.
It dumps the code into a database and lets you query it to find the relationships.
I'm biased, of course, but I've found it's just the thing to understand how a particular piece of functionality in an unfamiliar code base fits into the big picture.
