I suppose I should point folks to the video/story here, as well:

World's First "Unclonable" RFID Chip 320

Posted by ScuttleMonkey on Monday September 08, 2008 @02:04PM from the until-they-make-a-better-cloner dept.

An anonymous reader writes to tell us that a new RFID chip from Verayo claims to be unclonable through the use of the new Physical Unclonable Functions (PUF), sort of an electronic DNA for silicon chips. "Basic passive RFID chips can be easily cloned by copying the data residing on one chip to another. Verayo's PUF-based RFID chips cannot be cloned, and provide a very strong and robust authentication mechanism. No other chip or device can be disguised as the original chip, even if the data is copied from one Verayo RFID chip to another."

Yes, Hypercard was simply well-engineered so that anyone from a child to a high-end programmer (familiar with scripts, etc.) could use it from day 1 (more or less). I always like Hypercard. I was sorry to see it go. Newer program have been created that do similar things, but generally not with the elegant ease of Hypercard.

With Hypercard, you could do just about anything from presentations to simple adventure games. It was quite robust.

Successful Cold Fusion Experiment? 387

Posted by ScuttleMonkey on Saturday May 24, 2008 @05:26AM from the so-cold-it's-hot dept.

An anonymous reader writes "The italian economic journal 'Il sole 24 ore' published an article about a successful cold fusion experiment performed by Yoshiaki Arata in Japan. They seems to have pumped high pressure deutherium gas in a nanometric matrix of palladium and zyrcon oxide. The experiments generates a considerable amount of energy and they found the presence of Helium-4 in the matrix (as sign of the fusion). I was not able to find other articles about this but the journal is very authoritative in Italy. Google translations are also available."

World's Most Powerful Rail Gun Delivered to US Navy 615

Posted by ScuttleMonkey on Monday January 28, 2008 @04:19PM from the wanting-what-you-can't-have dept.

An anonymous reader writes "The world's most powerful functional rail gun capable of accelerating projectiles up to Mach 8 has been delivered to the Navy. The new rail gun is a 32-megajoule Electro-Magnetic Laboratory Rail Gun. The Navy eventually hopes to have 64-megajoule ship mounted rail guns. 'The lab version doesn't look particularly menacing -- more like a long, belt-fed airport screening device than like a futuristic cannon -- but the system will fire rounds at up to Mach 8, drawing on tremendous amounts of electricity to generate the current for each test shot. That, of course, is the problem with rail guns: Like lasers, they're out of step with modern-day generators and capacitors. Eight and 9-megajoule rail guns have been fired before, but providing 3 million amps of power per shot has been a limitation.'"
