Krugle - open source code search engine

I bumped into one of Krugle's developers at the Ajax experience conference. Looks like they just came out of beta and are open to the public. This is sweet, I can't emphasize enough how useful this is already proving. 90% of all code (I reckon) is boiler-plate, but by the time you've tracked down an implementation (and possibly ported it to your language of choice) its easier (say, 75% of the time) to just code it up yourself. Krugle changes that equation. This is going to be fun. Gripes - the frames and use of javascript: links make it difficult going on impossible to bookmark pages, blow out new tabs etc. Time to fire up Greasemonkey and fix it.
