Text Compressor 1% Away From AI Threshold
Baldrson writes "Alexander Ratushnyak compressed the first 100,000,000 bytes of Wikipedia to a record-small 16,481,655 bytes (including decompression program), thereby not only winning the second payout of The Hutter Prize for Compression of Human Knowledge, but also bringing text compression within 1% of the threshold for artificial intelligence. Achieving 1.319 bits per character, this makes the next winner of the Hutter Prize likely to reach the threshold of human performance (between 0.6 and 1.3 bits per character) estimated by the founder of information theory, Claude Shannon and confirmed by Cover and King in 1978 using text prediction gambling. When the Hutter Prize started, less than a year ago, the best performance was 1.466 bits per character. Alexander Ratushnyak's open-sourced GPL program is called paq8hp12 [rar file]." -
Compress Wikipedia and Win AI Prize
Baldrson writes "If you think you can compress a 100M sample of Wikipedia better than paq8f, then you might want to try winning win some of a (at present) 50,000 Euro purse. Marcus Hutter has announced the Hutter Prize for Lossless Compression of Human Knowledge the intent of which is to incentivize the advancement of AI through the exploitation of Hutter's theory of optimal universal artificial intelligence. The basic theory, for which Hutter provides a proof, is that after any set of observations the optimal move by an AI is find the smallest program that predicts those observations and then assume its environment is controlled by that program. Think of it as Ockham's Razor on steroids. Matt Mahoney provides a writeup of the rationale for the prize including a description of the equivalence of compression and general intelligence." -

Will There Be A Winning Autonomous Robot in 2005?
An anonymous reader submits "This summer is heating up the DARPA Grand Challenge as multiple top notch schools begin to announce their entry into the competition. The newest organization to announce its entry was the Florida Institute of Technology. Their project is known as Oasis - Autonomous Racing, and they have a team of over 45 students, professors, and advisors that are currently hard at work designing their vehicle and raising funds to pay for it. The DARPA Grand Challenge is a race between vehicles that should be designed to travel up to 300 miles in less than 10 hours through the desert or other harsh medium without any human interaction. The 2005 competition has a $2 million grand prize as authorized by congress. With all of the new entrants does anyone think that the competition will be won the second time around?" -
Jodrell Bank Telescope Gets No Signal From Beagle
tipiyano writes "Continuing the story of Beagle 2 from earlier today it seems like the hope for Beagle 2 surviving the landing at Mars is reducing as the Jodrell Bank telescope didn't receive any signal from Beagle. In the words of a mission manager, 'I wasn't too worried about the missed link with Odyssey, but it starts getting serious if Jodrell Bank cannot get a signal either'." -
Software Customer Bill of Rights
Cem Kaner of Badsoftware.com has written up a Software Customer Bill of Rights. Very appropriate considering our recent stories about Microsoft viruses, Dell's BIOS-clickwrap licensing agreement, etc.
