Free iTunes TV show downloads

MacRumors.com has a post that links to two free iTunes TV show downloads.  One is a Saturday Night Live short, the other is a Sci Fi channel special on Battlestar Galactica.

DRBD

Paul Westbrook | 22 December, 2005 18:06

I have been hearing about DRBD a while as a way to add redundancy for a server.  DRDB is a block device that can be mirrored across a network.  This is very similar to a network RAID-1.

I have been thinking about doing this for one of the databases that I use.  I could set up two machines that run mysql.  Only one machine at at time would be writing to the database and the file system, but both machines would have access to the files.  When one of the machines go down, the other automatically takes over.

Spam filtering in Apple Mail

Paul Westbrook | 22 December, 2005 17:25

I have been noticing that Apple Mail has been marking valid mail as spam pretty often, and it doesn't seem to be improving when I train with these mistaken spam messages. 

I had been thinking that Apple's Mail was using bayesian analysis to determine the spam messages.  But I just found out that Mail uses Latent Semantics analysis for spam filtering.  This post has a great description and comparison of Latent Semantics and Bayesian Net.
