Distributed.net Finds Optimal 25-Mark Golomb Ruler 265

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."

NASA's New Lunar Rover, Now Testing In Arizona 59

MarkWhittington writes "NASA has unveiled a new prototype lunar rover, called the Chariot, a production version of which is hoped to be operational on the lunar surface by 2019. NASA is now testing the Chariot lunar rover in Arizona, on terrain that resembles the lunar surface." Perhaps Arizona's an even closer match to the moon's surface than is Texas, or Moses Lake, WA where NASA was testing the last time we mentioned Chariot. (Here's a bit of video from the Texas round.)

What Normal Users Can Expect From Ubuntu 8.10 511

notthatwillsmith writes "With Ubuntu 8.10 due to be released in just a few days, Maximum PC pored through all the enhancements, updates, and new features that are bundled into the release of Intrepid Ibex and separated out the new features that are most exciting for Linux desktop users. Things to be excited about? With new versions of GNOME and X.Org, there's quite a bit, ranging from the context-sensitive Deskbar search to an audio and video compatible SIP client to the new Network Manager (manage wired, Wi-Fi, VPN, and cellular broadband connections in one place)."
