LED Lighting As Cheap As CFLs Invented 553

mcgrew writes "New Scientist reports that a British team has overcome the obstacles to cheap LED lighting, and that LED lamps as cheap as CFLs will be on the market in five years. Quoting: 'Gallium nitride cannot be grown on silicon like other solid-state electronic components because it shrinks at twice the rate of silicon as it cools. Crystals of GaN must be grown at 1000C, so by the time a new LED made on silicon has cooled, it has already cracked, rendering the devices unusable. One solution is to grow the LEDs on sapphire, which shrinks and cools at much the same rate as GaN. But the expense is too great to be commercially competitive. Now Colin Humphreys's team at the University of Cambridge has discovered a simple solution to the shrinkage problem. They included layers of aluminium gallium nitride in their LED design... These LEDs can be grown on silicon as so many other electronics components are. ... A 15-centimetre silicon wafer costs just $15 and can accommodate 150,000 LEDs making the cost per unit tiny.'"

More Claims From NSA Whistleblower Russell Tice 271

eldavojohn writes "Russell Tice, former NSA employee & whistleblower, has revealed yet more details claiming that wiretapping was combined with credit card data to target civilians. He also suggests the CEOs of major companies hold the truth: 'To get at what's really going on here, the CEOs of these telecom companies, and also of the banking and credit card companies, and any other company where you have big databases, those are the people you have to haul in to Congress and tell them you better tell the truth.' Will Congress follow his suggestions?" This adds to information revealed by Tice last week that the wiretaps targeted journalists in particular.

Submission + - Streaming Video from Mac to Linux?

Neuroprophet writes: My old dual PIII Ubuntu system finally dropped dead over the weekend. This was the machine I used with an ATI captrue card to transcode and stream video to my Powerbook G4 and eeepc. I'm now planning on using my Powerbook to be the video capture machine in place of my old PIII. I've looked into capture solutions like Elgato's hybrid and 250 plus, but the software doesn't support real time streaming to Linux. I've also read that real-time solutions like Cytv can be hit or miss. I haven't heard about much success with Hauppauge or Pinnacle devices either. Anybody currently streaming real time television from a Mac to a Linux box? Are there any particular tuners and software you would recommend? I'm looking for a solution using only my two current machines and a new capture device if possible.
