Everything You Ever Wanted To Know About CAPTCHAs But Were Afraid To Ask [Technology Explained] You Shall Not Pass (The Turing Test)! Captcha’s were invented by a team of Carnegie Mellon professors and put into first use around the year 2000 by AltaVista and Yahoo, in an attempt to prevent automated chat bots and URL submissions.

All but about a dozen of the questions had answers, although some were a bit brief. “Like any other consumer out there, I had problems with my Xerox printer, 700, Belkin wireless router and even Sony portable DVD,” Mr. Fixya rates the people who offer advice. Knowledge is only half of the battle. Most other gadgets come with batteries that are easy to replace without custom tools. Photo “Are they disposable?”
