Distributed.net Finds Optimal 25-Mark Golomb Ruler

kpearson writes "Distributed.net's 8-year-old OGR-25 distributed computing project has just proven conclusively that the predicted shortest 25-mark Golomb ruler is optimal. 'The total length of the ruler is 480, with marks at positions: 0 12 29 39 72 91 146 157 160 161 166 191 207 214 258 290 316 354 372 394 396 431 459 467 480. (This ruler may alternatively be expressed in terms of the distance between those positions, which is how dnetc displays them: 12-17-10-33-19-...).' 124,387 people participated in the project and two people found the shortest ruler, one on October 10, 2007 and the other on March 24, 2008."

    jsut to nip in there quickly, and this is effectively irrelavent, why the hell is everything tagged "story"? Tags are annoying enough without it, but at least (tagging beta) has gone, that was driving me nuts.

    Well, the be fair, the ones who answered 'yes' gave correct answers too. :-)

    I know. His answer was definitely more helpful than 'yes'. :-) [Though I think he should've added:

    In math, you can prove or disprove a conjecture [based on certain axioms (i.e., assumptions)]

    Yeah, but the winner of the first season of "Survivor", Richard Hatch, has managed to perform several examples of epic fail related to math, among other types of fail. For instance, he could not determine the result for 11*11 and choose an incorrect result on the Australian version of "Who Wants to Be a Millionaire?" This was the fourth question posed to him, so he walked away with nothing. Perhaps more damaging was that Hatch did not report his cash prize for winning "Survivor" to the IRS. Eventually the IRS noticed a problem in Hatch's returns, as one should always expect from the IRS and should surprise no one. In general, reporting discrepancies that are of a reasonable size will be investigated, especially those related to larger sized amounts, like Hatch did. As Hatch went through the legal system, he had several more instances of fail. These fail were mostly of the legal variety, IIRC he did manage have a lawyer and was unable to use frivolous tax avoidance arguments. Due to Hatch taking this approach, his lawyer avoided sanctions, like disbarment, and Hatch, avoided fines of up to $5000 for each instance, which can and are assessed regularly in Tax Court. In any case, the threat of disbarment, means that wacky discredited legal theories will not be used by defense lawyers who want to continue on their current career path. In any case, Hatch ended up with a sentence of 4 years, 3 months, and will not spend his time in a maximum security facility. Hatch has a release date of October 2009. However, something that may negate any benefits of a lower security level is that Hatch is now idiling his time away at a prison, in an armpit of a state, West Virginia.

    I read the summary and I was like " wow, what the fuck are they talking about?" Then I read your post and was like "wow, what the fuck is he talking about?

    The difference is of course, that Apple and MS are not people.

    Although personally, I'm not particularly statist about Apple and Microsoft. I just wish they would stop being cunts.

    IMO, libertarianism, like communism, is heavily reliant on empathy. Neither will work until people realize they have to stop being nasty to each other for the world to progress beyond its current level of barbarism.
