Despite my griping, I liked kdb+ and q. As a database query language, q is awesome, if you are doing a lot of time-series analysis (running sums, etc., nothing fancy). As a language, the table type in q is very nice, a bit like what pandas or data.table wish they could be.

For a while there was a freely downloadable version to try out, and you can look at "q for mortals", http://code.kx.com/q4m3/, to get some flavor.

They just made the 64 bit version free for experimenting with. It is annoying because it only will start up and run if you are connected to the internet, but it fully works. The 32 bit version can be downloaded as well and that fully works, with or without internet connection.
