Dollaz wrote with a link to the International Business Times, which questions the authenticity of D-Wave's Quantum computing. We discussed the 'Sudoku playing' computer yesterday, but scientists in the field have expressed a lot of distrust of the company's findings. The machine was not available for inspection during or after the demo, and even if the technology was working as intended there is some doubt that it can be scaled. The article points out that "notwithstanding lofty claims in the company's press release about creating the world's first commercial quantum computer, D-Wave Chief Executive Herb Martin emphasized that the machine is not a true quantum computer and is instead a kind of special-purpose machine that uses some quantum mechanics to solve problems." Good to see people in the field questioning 'breakthroughs'.

In the article O'Brian tells of how 'witnesses at Thursday's hearing painted a bleak picture of that system. Adam Jaffe, a Brandeis University professor and author of a book on the subject, described the system as 'out of whack.' Instead of 'the engine of innovation,' the patent has become 'the sand in the gears,' he said, citing widespread fears of litigation. The House Oversight Committee website has more details. How would you fix the patent system?"

Chester Freeze writes "During the holiday season, many shoppers bought PCs with the promise of quick, free Vista upgrades. The reality has been something else entirely: many Dell and HP customers are being told that they won't receive their copies of Vista before April. 'One source at a major OEM who spoke on condition of anonymity said that the real issue is that OEMs are still not sure which PCs are really ready to support Vista, and which PCs aren't... Customers who qualify for an Express Upgrade also qualify for OEM support for Windows Vista, even if their machines came with Windows XP. The last thing a Dell, Gateway, or HP wants to do is start sending out upgrades to customers who might have video cards that do not have particularly stable drivers yet (or sound cards, or RAID controllers, etc.). This could be a support disaster.'"
