reCaptcha - Humans help with OCR

Great idea to get literature that is hard to scan OCR'ed: reCaptcha

About 60 million CAPTCHAs are solved by humans around the world every day. In each case, roughly ten seconds of human time are being spent. Individually, that's not a lot of time, but in aggregate these little puzzles consume more than 150,000 hours of work each day. What if we could make positive use of this human effort? reCAPTCHA does exactly that by channeling the effort spent solving CAPTCHAs online into "reading" books.

XenServer, Davical, and stuff...

I'm doing a late start in terms of work today - after a long weekend with no work for employer stuff, I couldn't get into it too early...

I guess I'll start with taking my XenServer course, so I'll be able to pass a certification for this in the next 2 weeks.
