I've been reading up a bit on jQuery, a small, modular, and very expressive JavaScript library. There is a large collections of plug-ins, which build on it and extend its functionality in numerous ways. It's a bit hard to separate the wheat from the chaff, but there are many interesting pieces in there.

A particularly interesting set of extensions is jQuery UI - I really like the way you can pick and choose what you want and get a personalized package with a few mouse clicks on the download builder page.

One of the countless projects of mine which never materialized was the "Standalone Executable Assembly Line" (SEAL). I still think it would be very useful. So would a much simpler system which does this for pure Tcl scripts, btw (or Lua, Python, Ruby, whatever).

Not enough hours in the day. Nor years in a lifetime.
