Submission + - Should Google Go Nuclear?

Baldrson writes: "One of the founders of the US Tokamak fusion program, Dr. Robert W. Bussard, gave a lecture at Google recently now appearing as a Google video titled "Should Google Go Nuclear?" in which he presents his recent breakthrough electrostatic confinement fusion device which he claims produced several orders of magnitude high fusion power than earlier electrostatic confinement devices. According to Bussard, it did so repeatably during several runs until it blew up due to mechanical stress degradation. He's looking for $200M funding, the first million or so of which goes to rebuilding a more robust demonstrator within the first year. He claims the scaling laws are so favorable that the initial full scale reactor would burn boron-11 — the cleanest fusion reaction otherwise unattainable. He has some fairly disturbing things to say in this video, as well as elsewhere, about the US fusion program which he co-founded."

Submission + - Ratushnyak Wins First Hutter Prize Payout

Baldrson writes: "Alexander Ratushnyak (middle) of the Moscow State University Compression Project is the first winner of The Hutter Prize for Lossless Compression of Human Knowledge which was announced here August 13. On 25 Sep 2006, within two months of the announcement of the Hutter Prize, Alexander Ratushnyak submitted his program paq8hp5 which compressed the first 100MB of Wikipedia down to 17,073,018 bytes. As required by the contest, this size includes a program which must be capable of decompressing the 100MB sample of Wikipedia within a reasonable time using widely-available desktop computer hardware resources. This is a whopping 6.8% improvement over the contest baseline and compares very favorably with the historic rate of progress in text compression of approximately 3% per year, even accounting for "low-hanging-fruit" under customization of compressors for new benchmark corpora.

paq8hp5 is the first text compressor to reduce to practice the theoretic possibility of using semantic associations between words — a form of language modeling.

At Alexander Ratushnyak's request, part of the 3416 euro (500 euro for each percent improvement) prize will go to Przemyslaw Skibinski of the University of Wroclaw Institute of Computer Science for his early contributions to the underlying PAQ compression algorithm.

Matt Mahoney has a further write-up on the history of this lineage of text compressors as well as his announcement of the payout in alt.ai.nat-lang."

Submission + - The X-Prize Cup Flights of Pixel

Baldrson writes: "John Carmack has put up a page of videos and photos of the flights of Pixel along with a text narrative at the Armadillo Aerospace website. Although Armadillo Aerospace did not win the sought-after Lunar Lander Challenge Prize the flights were quite reminiscent of the famous test flight of the Delta Clipper which set higher expectations for speed and economy of development in aerospace. To put things in perspective the Delta Clipper cost tens of millions and set a record for reusable rocket flights at 26-hour turnaround. The Pixel cost hundreds of thousands of dollars and had a turnaround between flights almost 10 times faster."

Submission + - Video of Armadillo Aerospace's X-Prize Cup Flight

Baldrson writes: "Armadillo Aerospace's 1 minute 35 second X-Prize Cup hovering rocket flight is toward the end of this video. This flight was part of the $2M Lunar Lander Challenge prize competition — aimed at winning the $350,000 Level One prize. As blogged by space journalist Leonard David the first leg of the flight, shown in the video, was successful but the second leg of the flight failed near lift-off."

Submission + - Netflix Progress Prize May Already Be Won

Baldrson writes: "Merely a week after the announcement of The Netflix Prize a "The Thought Gang" team has already beaten the threshold for the 2007 Netflix Progress Prize of $50,000. This is pretty impressive given the previously quoted researcher who said: 'You're competing with 15 years of really smart people banging away at the problem.' Congratulations are in order for Netflix and "The Thought Gang" team, whoever they are, for demonstrating, yet again, the power of prizes to accelerate progress."

Submission + - Netflix Offers $1M Prize For Algorithm

Baldrson writes: "The Netflix Prize is offering a $1 million Grand Prize for the first team to publish an algorithm that can predict how a customer will rate a movie based on prior ratings 10% more accurately than Netflix's current algorithm. Netflix provides their movie rating data as the training set and benchmark. There is also a $50,000 annual progress prize for the algorithm showing the most progress during the prior year. The contest began 2 days ago and lasts for 5 years. For an idea of how fast the Netflix Grand Prize could be awarded: Within 2 months of the recent announcement of The Hutter Prize for Lossless Compression of Human Knowledge, there was an entry purporting 6.8% improvement over prior text compression algorithms although it is still in the public comment/judging period. The Hutter Prize currently offers just 5000 Euros for each percent improvement, compared to the $100,000/% for The Netflix Grand Prize. Keep in mind prediction and compression are equivalent capabilities and you might see the urgency of getting your team off the starting block fast."

Submission + - Paypal Co-Founder Backs Anti-aging Research Prize

Baldrson writes: "Anti-aging researchers, via The Methuselah Mouse Prize or M-Prize, are receiving an additional $3 million incentive, to stop and reverse aging. Researchers win M-Prize money in increments by breaking longevity records for mice or reversing their aging. The philanthropic donation comes from Peter Thiel co-founder and former CEO of PayPal. Mr. Thiel has pledged to match each dollar donated to the M-Prize with his own 50 cent contributions up to $3 million."
