This is super cool.
You've probably seen CAPTCHAs before: the funny looking words that you have to type in when posting on Craigslist or creating a new account... anywhere.
(Or posting a comment on this blog, even!)
These funny looking words are supposed to keep people from programming computers to automatically spam. The thing is the spammers get good at writing software to decipher these puzzles.
But a university was trying to use computers to digitize really old books, and the computers just couldn't do it.
Eureka! We KNOW computers can't decipher these old books. We want the text deciphered, and we want to stop spammers. Synergy. Now MySpace and several other big sites are using this technology to stop spammers, and it's helping archive our historical knowledge.
Awesome.
