wisdom-of-crowds and Rock-Paper-Scissors

SuperchrunhersDamn, hate loosing - but this little exhibition in my own statical predictability irritates me

Been playing Rock-Paper-Scissors for 5 min and lost significantly - even when trying to counter my own thinking pattern ....

Slightly sidetracked after checking out superchrunchers

BBC Berkshire: Flood Map

BBC Berkshire: Flood Map - situation report on google maps, with user-contributed pictures/videos.
When the next generation of camera's with support for gps/geo tagging hits mainstream we will probably see things like this a lot more - until then a low cost software solution for geotagging would be robogeo for $39.95.
Adding robogeo to my to-buy list.

recaptcha or Captcha meet wisdom-of-crowds

Got a beta invite to polarrose ("The Polar Rose browser plugin lets you discover who's in any public photo") and got sidetracked by a link while reading the polarrose blog to recaptcha.net


Love the idea behind reCaptcha, the service generates Captcha's from failed OCR at the internet archive;

"eCAPTCHA 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."

Apparently reCaptcha were conceived by Luis von Ahn who also happens to be the man behind Google Image labeler.

I've registered an account at recaptcha.net and will definitely use this service on a forthcoming website I'm working on.

reCaptcha offers a free captcha email protection service also at mailhide.recaptcha.net. Think I will reCaptha my email adresses instead of using this javascript email address obscuring script from projecthoneypot

Note, did find the audio version of reCaptcha a bit difficult to hear ...... glad I can read

Great example of utilizing wisdom-of-crowds to provide a real service. Nice tagline they got "stop spam - read books"

The polarrose service I'll blog about when I've got time to play around with the service
