Comment the problem will not go away even without leaps (Score 3, Informative) 470

The historical record of time_t is already ambiguous and cannot be corrected by abandoning leap seconds. There is a way to get leap seconds out of the kernel and into user space which amounts to reclassifying them as decrees of change of civil time and putting them into zoneinfo while letting the broadcast time scale not have leaps. It's a matter for posterity whether the word "day" will be re-defined by the ITU-R, changed from the current treaty-specified "mean solar day" to a technically-defined "atomic day".

Black Hole Emits a 1,000-Light-Year-Wide Gas Bubble 145

PhrostyMcByte writes "12 million light-years away, in the outer spiral of galaxy NGC 7793, a bubble of hot gas approximately 1,000 light-years in diameter can be found shooting out of a black hole — one of the most powerful jets of energy ever seen. (Abstract available at Nature.) The bubble has been growing for approximately 200,000 years, and is expanding at around 1,000,000 kilometers per hour."

Submission + - Vatican chooses open FITS image format (typepad.co.uk)

@10u8 writes: The Vatican Library plans to digtize 80000 manuscripts and store them in the open data format FITS, originally developed for astronomy and maintained under the IAU. The result is expected to be 40 million pages and 45 petabytes. FITS was chosen because it 'has been used for more than 40 years for the conservation of data concerning spatial missions and, in the past decade, in astrophysics and nuclear medicine. It permits the conservation of images with neither technical nor financial problems in the future, since it is systematically updated by the international scientific community.'

Submission + - Lego Robot Solves Bigger and Harder Rubik’s (singularityhub.com)

kkleiner writes: It was only two months ago that we saw Mike Dobson's Cube Stormer Lego robot that could solve any 3x3 Rubik's cube in less than 12 seconds. You would think that there was only one person in the world crazy enough and talented enough to pull this off, but now we have found someone else that is just as amazing. The latest Rubik’s cube solving Lego monstrosity is called the MultiCuber and although it’s constructed out of nothing but Mindstorms components and a laptop, it can solve 2×2, 3×3, 4×4, and 5×5 cubes all in the same build! As if that wasn’t enough, a larger version solves the dreaded 6×6 Rubik’s. We discovered the MultiCuber when its creator, David Gilday (IAssemble), wrote us an email to brag about its puzzle solving might. Consider us impressed, sir.
