I can't say that i've ever used Unix (as we all know GNU's not Unix), but extrapolating your statement implies that *nix is less professional than Windows.
I disagree.

BTW Google sucks. You can't google "*nix". There's no escaping.
I do understand why it needs to suck, but it still sucks...

Submission + - Pouring Water Into a Volcano to Generate Power

Hugh Pickens writes writes: "Until recently, geothermal power systems have exploited only resources where naturally occurring heat, water, and rock permeability are sufficient to allow energy extraction but now geothermal energy developers plan use a new technology called Enhanced Geothermal Systems (EGS) to pump 24 million gallons of water into the side of the dormant Newberrry Volcano, located about 20 miles south of Bend, Oregon in an effort to use the earth's heat to generate power. "We know the heat is there," says Susan Petty, president of AltaRock Energy, Inc. of Seattle. "The big issue is can we circulate enough water through the system to make it economic." Since natural cracks and pores do not allow economic flow rates, the permeability of the volcanic rock can be enhanced with EGS by pumping high-pressure cold water down an injection well into the rock, creating tiny fractures in the rock, a process known as hydroshearing. Then cold water is pumped down production wells into the reservoir, and the steam is drawn out. Natural geothermal resources only account for about 0.3 percent of U.S. electricity production, but a 2007 Massachusetts Institute of Technology report projected EGS could bump that to 10 percent within 50 years, at prices competitive with fossil-fuels. "The important question we need to answer now," says USGS geophysicist Colin Williams, "is how geothermal fits into the renewable energy picture, and how EGS fits. How much it is going to cost, and how much is available.""

Says the website, 'OpenVSP allows the user to create a 3D model of an aircraft defined by common engineering parameters. This model can be processed into formats suitable for engineering analysis.'"

Submission + - Raspberry Pi beta boards unveiled 1

Submitted by anwe79
anwe79 writes: Those of you who have been wishing for a Raspberry Pi this christmas will sadly not get your wish granted. However, you may be happy to hear that populated beta boards have now been produced. Beta of course means the boards still have some more testing to undergo. But, if all goes well, those inclined should be able to get their hands on production boards in January!

Head over to http://www.raspberrypi.org/ for some juicy pics and more details.

Submission + - Stamping out low cost nanodevices (vanderbilt.edu)

Submitted by RogerRoast
RogerRoast writes: Vanderbilt University scientists report that they have developed a simple technique for stamping patterns invisible to the human eye on to special class of nanomaterials. According to the article, the method works with materials that are riddled with tiny voids that give them unique optical, electrical, chemical and mechanical properties. “It’s amazing how easy it is. We made our first imprint using a regular tabletop vise,” Sharon M. Weiss the lead author said. The article was published in the latest issue of the journal Nano Letters
