Note: Russ Cox is also part of the Go team at Google and was in charge of building Code Search(RIP) and when it was shut down he released the core of the indexing engine: http://code.google.com/p/codesearch/
He also wrote RE2 [1] and has published a few articles on regular expression matching [2]. I highly recommend taking some time to look through his blog, he's got some great stuff there.
This, as usual, is amazing. Russ is just ridiculous. I range between being deeply jealous of him and deeply impressed at the productivity and quality of his work :-)
I am trying to get this working on Windows - any ideas? I downloaded the Go build for windows (https://code.google.com/p/go/downloads/list) yet I have no idea how to build this app (QR.go)
He was just as insanely productive even before he joined Google, for a while he was both at Bell Labs (hacking on Plan 9, venti, and other things) and at MIT (hacking on vx32, the modern-C rewrite of the original Unix V6 kernel, etc.)
I'm surprised how quickly this ended up on HN. I submitted it to Hack a Day late last night (early morning?), and was surprised that Hack a Day got it online by the time I left the house.
