Comment Re:It could be built by the neanderthals (Score 2) 50

Has the timeline been changed by better archaeology or dating, or reclassification of remains? when I was at school (only 2 decades ago, in the UK) I was taught that the last Neanderthals died out around the time of the construction of the Pyramids in Egypt, no more than 6000 years ago

Just asked my sis (who sports a B.A. in prehistoric archaeology )... according to her, you must've had a very strange teacher -- historically, the figure for "how long ago did they die out" has been creeping down as more and more recent specimen were found. At no time did people think it was just 6ka ago.

I try the same every spring whenever we switch to DST (which for me is UTC+2), but I give up after a week or so because it gets confusing with different web services (calendars, bug trackers etc) and my own devices being in different time zones

Submission + - How to Make an 'Energy Efficient' Warp Drive (discovery.com)

astroengine writes: "Sonny White, of NASA's Johnson Space Center, presented his warp drive calculations at the 100 Year Starship symposium earlier this month. By White's reckoning, his design of starship — that is "adjusted into more of a rounded doughnut, as opposed to a flat ring" and oscillates the warp intensity — could be powered by the approximate mass-energy of the Voyager 1 space probe. Of course, this is a lot of energy, but how does it compare to previous estimates? In 1994, physicist Miguel Alcubierre — who is widely considered the first to formalize the physical theory behind the warp drive — found that his warp drive would need all the mass-energy in the Universe to function. But in 2009, Baylor University physicist Richard Obousy applied our current understanding of quantum dynamics, dark energy and string theory to the warp drive. His system could theoretically be powered by the rest-mass energy of Jupiter. Better, but still not great. Although White's warp drive would still need the entire annual energy usage of the United States, suddenly (assuming all the "exotic" assumptions are proven) warp speed doesn't seem so prohibitively power hungry."

What do you want to imply?

That, somehow, he who does not know how to debug the kernel should not play with bit operations?

Something like that?

  Or, that we should stop researching the structure of the universe, and instead focus on what we usually do, which is making war, screwing other people and post photos of our dicks on teh internet?
