Wuala is a p2p backup and remote storage service.  It gives you 1GB of backup space for free and more when you share disk space with others.  If you have a large amount of data or multimedia to backup then this is a much cheaper alternative to services such as Mozy.  All your data is encrypted and replicated multiple times.  There is a very interesting Google tech talk on the subject which shares some insights into the workings of Wuala.  I found the portion dealing with erasure codes to be particularly interesting.  Contact me if you’d like an invite to Wuala.

Also, you may have noticed the pace of blogging my has slowed.  I’ve been extremely busy recently and expect this to continue for the next month or two.  Nonetheless, I am going to make time to post a series of Struts 2 tutorials based off a presentation I gave a few months ago.
