HP Patents Bignum Implementation From 1912 144

I Don't Believe in Imaginary Property writes "The authors of GMP (the GNU Multiple Precision Arithmetic Library) were invited to join Peer-to-Patent to review HP's recent patent on a very old technique for implementing bignums because their software might infringe. Basically, HP's patent claims choosing an exponent based on processor word size. If you choose a 4-bit word size and a binary number, you end up working in hexadecimal. Or for a computer with a 16-bit word and a base-10 number, you use base 10,000 so that each digit of the base-10,000 number would fit into a single 16-bit word. The obvious problem with that is that there's plenty of prior art here. Someone who spent a few minutes Googling found that Knuth describing the idea in TAOCP Vol. 2 and other citations go back to 1912 (which implemented the same algorithm using strips of cardboard and a calculating machine). None of this can be found in the 'references cited' section. Even though the patent examiner did add a couple of references, they appear to have cited some old patents. The patent issued a few months ago was filed back in October of 2004, and collected dust at the USPTO for some 834 days."

Kepler Finds Five More Exoplanets 102

Arvisp was one of several readers to send news of five new exoplanets discovered by the Kepler space telescope. In addition to the new "hot Jupiters" — the easiest targets to find — Kepler's early data has turned up some oddities, including something that is too hot to be a planet and too small to be a star. And one of the exoplanets is so fluffy that "it has the density of Styrofoam." The real news is that Kepler works as designed, and the scientists running it are fully confident that it will find Earth-like planets in some star's habitable zone, if they are out there to be found. Here is NASA's press release.

INTERPOL Granted Diplomatic Immunity In the US 450

ShakaUVM writes "A couple of weeks ago without any fanfare or notice in the media, President Obama granted INTERPOL full diplomatic immunity while conducting investigations on American soil. While INTERPOL has been allowed to operate in the US in the past, under an executive order by President Reagan, they've had to follow the same rules as the FBI, CIA, etc., while on American soil. This means, among other things, the new executive order makes INTERPOL immune to Freedom of Information Act requests and that INTERPOL agents cannot be punished for most any crimes they may commit. Hopefully the worst we'll see from this is INTERPOL agents ignoring their speeding tickets." Update: 01/05 02:57 GMT by KD : Reader davecb pointed out an ABC News blog that comes to pretty much the opposite conclusion as to the import of the executive order.
