Capcha

Just to lighten the mood, I thought I would share a capcha my friend got from our uni web site...

You had any interesting ones?

Your likely to encounter strange ones because they are actual words taken from OCR'd books.

reCAPTCHA improves the process of digitizing books by sending words that cannot be read by computers to the Web in the form of CAPTCHAs for humans to decipher. More specifically, each word that cannot be read correctly by OCR is placed on an image and used as a CAPTCHA. This is possible because most OCR programs alert you when a word cannot be read correctly.

But if a computer can't read such a CAPTCHA, how does the system know the correct answer to the puzzle? Here's how: Each new word that cannot be read correctly by OCR is given to a user in conjunction with another word for which the answer is already known. The user is then asked to read both words. If they solve the one for which the answer is known, the system assumes their answer is correct for the new one. The system then gives the new image to a number of other people to determine, with higher confidence, whether the original answer was correct.

why they can't be strange though?

saw a picture for one on facebook for what i think said 'gay lord', made me chuckle.

Well the chances are if it's a word from a real book it's going to be something you can read rather than random characters generated by some algorithm. This increases the chances of strange combinations of words.
