It was another slow news day but there is still plenty of good reading. On Java Code Geeks, we get a good post on using TF-IDF in practice. This is one of the main indexing methods behind libraries like Lucene, so if you are interested in document searches or indexing in general, it is a good article to check out. MIT Technology Review gives us a good overview of a study about how and why humans make mistakes. There are some interesting nuggets of information in the article, but overall it might not be that surprising to people. At Software Is Crap, we get an excellent rant about building rotten foundations, with a focus on the GTK framework. There is some good opinion on writing and maintaining APIs in between the complaints about GTK.

As always, enjoy today’s items, and please participate in the discussions on these sites.
