derekmead writes "3D-printing gun parts has taken off, thanks to the likes of Cody Wilson and Defense Distributed. While the technology adds a rather interesting wrinkle to the gun control debate, the ATF currently is pretty hands-off, ... 'We are aware of all the 3D printing of firearms and have been tracking it for quite a while,' Earl Woodham, spokesperson for the ATF field office in Charlotte, said. 'Our firearms technology people have looked at it, and we have not yet seen a consistently reliable firearm made with 3D printing.' A reporter called the ATF's Washington headquarters to get a better idea of what it took to make a gun 'consistently reliable,' and program manager George Semonick said the guns should be 'made to last years or generations.' In other words, because 3D-printed guns aren't yet as durable as their metal counterparts, the ATF doesn't yet consider them as much of a concern."

For many decades, gramophone records (the black vinyl discs in Grandma's attic) were made by cutting grooves directly into an acetate disc, then making a mold from that "master" and "pressing records." Nowadays, of course, we use digital recording software on our computers or even on our mobile phones. Vinyl? Strictly for fogies and maybe a few audiophiles who think analog recordings have a depth and warmth that CDs and MP3s lack. Naturally, SXSW is a haven for these folks, and among them Tim Lord found Wesley Wolfe and two German compatriots from vinylrecording.com, busily demonstrating their vinyl recording system, which is sort of the gramophone record equivalent of print on demand. Lots of background music in the video makes the voices a bit hard to hear; some might prefer the transcription -- although those who do will lose out on watching the vinyl recording machine in action. Either way. Or both. Up to you.
Nerval's Lobster writes "French oil conglomerate Total has inaugurated the world's ninth-most-powerful supercomputer, Panega. Its purpose: seek out new reservoirs of oil and gas. The supercomputer's total output is 2.3 petaflops, which should place it about ninth on today's TOP500 list, last updated in November. The announcement came as Dell and others prepare to inaugurate a new supercomputer, Stampede, in Texas on March 27. What's noteworthy about Pangea, however, is that it will be the most powerful supercomputer owned and used by private industry; the vast majority of such systems are in use by government agencies and academic institutions. Right now, the most powerful private supercomputer for commercial use is the Hermit supercomputer in Stuttgart; ranked 27th in the world, the 831.4 Tflop machine is a public-private partnership between the University of Stuttgart and hww GmbH. Panega, which will cost 60 million Euro ($77.8 million) over four years, will assist decision-making in the exploration of complex geological areas and to increase the efficiency of hydrocarbon production in compliance with the safety standards and with respect for the environment, Total said. Pangea will be will be stored at Total's research center in the southwestern French city of Pau."
