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. It is in fact an acronym for Completely Automated Public Turing test to tell Computer and Humans Apart. For those of you who don’t know what that means, it may help to explain what the Turing test is. The CAPTCHA therefore, is an automated Turing test.

Don’t Throw Out Your Broken iPod; Fix It via the Web Yaniv Bensadon, the chief executive of fixya.com, started his site after he moved back to Israel from the United States and found that his electronics would often malfunction in the new environment. The manuals and the support offered by the manufacturers rarely helped. His site groups questions and answers to problems and organizes them according to product type, brand name and model number. The page for the 360, for instance, lists more than 100 questions with answers. Most provide a single solution, but one common problem, overheating, has 81 posts debating the best fix. 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?”
