Over at the Programming Praxis blog, the task of the day is to write a program to solve the game Mastermind. Mastermind is actually a fairly interesting game mathematically speaking, and has a fairly rich set of mathematics behind it, and yet it's actually small enough to analyze easily using modern computing power. I might try to use this as a test program to try out the new Go programming language from Google. In the mean time, here are some links:

Dan Lyke of flutterby drew my attention to the astrometry pool on Flickr. If you upload an astrophotograph to this group, a process comes by later and tries to identify the stars in your image, and adds annotations and labels to it. Very nifty. Check it out. Try clicking the image above, and it will send you to the Flickr page with the annotations.
