The article cited refers to software planted on the phone exchange, not the towers. The rogue wiretapping software was essentially a rootkit, complete with a backdoor for future access and detection countermeasures.

Very well put. I didn't have space to explain this in the submission's summary, but this is the gist of the paper.

Using identity-based signatures and time-stamped tokens they report a 99.9 percent prevention rate in Gnutella, KaZaA, and Freenet and a 85-98 percent prevention rate on eMule, eDonkey, and Morpheus. Poison-resilient networks based on the BitTorrent protocol are not affected. Also the system can't protect small files, like a single song MP3. Although the authors don't say so explicitly, my understanding is that the scheme is only useful on commercial p2p distribution systems that adopt the proposed protocol."

The article explains that AMD requires the cash to address three handicaps it has in its fight against Intel: its smaller number of fabs, which increases its exposure to manufacturing problems, its lack of Intel's dominant position, and its need to pay for strategic acquisitions, like that of ATI. The article ends by warning that in a, widely expected, industry slowdown resource-rich countries will be able to buy big chunks of US's high-tech industry at bargain prices. Following the recent descriptions of attacks against cryptographic algorithms based on CPU backdoors, will these purchases end-up to be the high-tech equivalent of the Dubai Ports World controversy?"

A one-year pilot Peer-to-Patent program for selected patent applications is now online. The most active team currently reviews a patent on a method, apparatus and computer program product for providing status of a process. The IEEE Spectrum has an interview with the founder of Peer-to-Patent New York Law School's Professor Beth Simone Noveck."

The laptop, in common with the hardware of the one laptop per child initiative, uses solid state memory for storage and runs Linux. It weights 900g (2 lb) and measures 120 * 100 * 30mm (4.7 * 4 * 1.2"). I'm currently using an actual OLPC for localization work and experiments with educational applications, and I was dreaming being able to buy similar machines to use as cheap and cheerful terminals around the house. With Quanta having made a similar product announcement it seems that the Star Trek nirvana of a computer in every room can become an affordable reality."
