[FoRK] Kdb+ now available free for non-commercial use (or something)

Brief intro:  Kdb+ and q is an integrated database and programming  
language developed by Arthur Whitney, a Ken Iverson protege.  It is in  
a sense an APL derivative w/o all the funny characters, and oriented  
towards large-scale data mining and statistical analysis, particularly  
finance apps and other forms of time series wrangling.  It's blazingly  
fast and extremely terse (perhaps, maybe even probably, too much so.)   
It's got an interesting pedigree;  its immediate predecessor was  
developed under contract and was a proprietary product for one of the  
big banks (UBS or Morgan Stanley, can't recall off the top of my head)  
and then after several years morphed into a commercial (and previously  
VERY expensive) product.

If you're into esoteric languages, data wrangling, or doing things  
"different" you might want to check out the license, download if  
appropriate, and give it a whirl.  If nothing else it's an interesting  
source of ideas.
