October 23, 2012 I've posted a sample Haskell program. This is a rewrite of my "Spider" adventure game, which I picked as an example of a program where a lot of state had to be handled. Learn from my mistakes!

For those interested in the upcoming U.S. elections:

Over the years I have found UPenn's own Annenberg center to be an excellent source of unbiased information. It checks the validity of the various claims made by politicians, and spares nobody. Two of their sites are factcheck.org and flackcheck.org.

For a less balanced point of view, see the Details of the Romney/Ryan Tax Plan.

There is a simple IDE for Clojure, called Clooj. Last year it didn't work very well, but it's gotten better. I've been playing with Clooj a little, but I still think jEdit with the Clojure plugin is nicer.

September 21, 2012 I have posted three versions of the Clojure pretest (see below). They are identical, except for the version of Java that was used to compile them.
