    sunhou writes "A couple of months ago, researchers tested a solar-powered autonomous underwater vehicle (SAUV) at RPI's Darrin Fresh Water Institute. (More pictures and links to info available at the Autonomous Undersea Systems Institute.) Current autonomous underwater vehicles (AUVs) need to be taken out of the water often to have their batteries recharged. The goal is to have groups of cooperating SAUVs loaded with sensors and networking equipment deployed on long-term monitoring missions. Watch out Sky-Net, here comes Sea-Net! (See also the recent story about The Argo Project.)"

  2. Challenges in Releasing Open Source Software?

    Chris Vaughan asks: "Me and my Co-Workers at the Advanced Computing Research Lab are just about ready to release our first Open Source package on SourceForge.net I ask the Slashdot community what hurdles they had to overcome and how much involvement do they still have in their project years later. Also what types of licensing did you pick and why did it suit your project best? Our project, MyPBS is a PHP/MySQL/Perl frontend accounting package for the Portable Batch System (PBS). Which is used to account for super computing usage. I appreciate any comments you may have."

  3. The "Omega Number" & Foundations of Math

    speck writes "Here's a link to an article in New Scientist about mathemetician Gregory Chaitin, who seems to have thrown some of the basic foundations of math into question with his work on the 'omega number.' Among the more provocative statements in the article: '[Chaitin] has found that the core of mathematics is riddled with holes. [He] has shown that there are an infinite number of mathematical facts but, for the most part, they are unrelated to each other and impossible to tie together with unifying theorems. If mathematicians find any connections between these facts, they do so by luck.' Also of interest is the transcript of a lecture Chaitin gave at CMU, which explains some of the theory in quite accessible language."
