Cosmos: A Spacetime Odyssey Is New Must-See Geek Show
Nebula One turns servers into simple, private clouds with OpenStack (video)
Trying to create a large-scale, private cloud array can be a headache, since it often involves bringing disparate networking, server and storage systems together in one not-so-happy union. Wouldn't it be nice to have a box that could do most of the hard work? Nebula thinks its newly launched Nebula One controller will do the trick. The rackmount device's Cosmos OS quickly turns ordinary servers from the likes of Dell or HP into a unified cloud computer that centers on the more universal OpenStack platform, and which can also talk to Amazon Web Services. IT admins have a single interface to oversee the whole lot while skipping any outside help, and can scale up to a hefty 1,600 processor cores, 9.4TB of memory and 2.3PB of storage. You'll have to ask Nebula directly about pricing, although we suspect it's counting on the classic battle between time and money to clinch a deal -- the weeks saved in setup and maintenance could represent the real discount.

Scientists create simulation of the universe, reenact 14 billion years in a few months (video)
Are animations of Curiosity's Mars landing not enough to feed your space exploration appetite? Try this on for size: a group of scientists from the Harvard-Smithsonian Center for Astrophysics and the Heidelberg Institute for Theoretical Studies have generated what's billed as a full-fledged simulation of the universe. Arepo, the software behind the sim, took the observed afterglow of the big bang as its only input and sped things up by 14 billion years. The result was a model of the cosmos peppered with realistically depicted galaxies that look like our own and those around us. Previous programs created unseemly blobs of stars instead of the spiral galaxies that were hoped for because they divided space into cubes of fixed size and shape. Arepo's secret to producing accurate visualizations is its geometry; a grid that moves and flexes to mirror the motions of dark energy, dark matter, gasses and stars. Video playback of the celestial recreation clocks in at just over a minute, but it took Harvard's 1,024-core Odyssey super computer months to churn out. Next on the group's docket is tackling larger portions of the universe at a higher resolution. Head past the jump for the video and full press release, or hit the source links below for the nitty-gritty details in the team's trio of scholarly papers.
