Submission + - Rockbox dev interview: Open source firmware (

angry tapir writes: "I recently caught up with some of the key developers of Rockbox: An open source firmware replacement for the stock firmware shipped on MP3 players. The project, which has been active for over a decade, currently supports products from more than half a dozen manufacturers, including Apple, Arhcos, iRiver and Toshiba. It involves extensive reverse engineering to figure out how the devices' stock firmwares operate, as well as the challenge of developing for greatly varied targets. You can read the interview here (or the full Q&As with the project's founder and some of the developers involved in it)."

Submission + - OLPC's $75 Tablet Debut Delayed 45 Days (

CWmike writes: Nicholas Negroponte, chairman of One Laptop Per Child project, said that the $75 XO-3 tablet computer will now debut sometime in February 2011, about 45 days later than originally planned. He said that he wants the screen to be flexible so that it is more resistant to breaking, but that it doesn't need to roll up. 'The issue has been really finding an unbreakable material, which may not be plastic, it may be glass or some flavor of glass,' he said during a video interview at MIT. At first the XO-3 won't be branded OLPC, rather made by Marvell, with the actual XO-3 to follow. The tablet will eventually cost $75 and during a May 2010 interview, Negroponte said hitting that mark wouldn't be a problem. Negroponte said that the job of the XO-3 is 'pushing where normal market forces wouldn't otherwise.'

Aussie Research Company Brings Wi-Fi To TV Antenna 74

joshgnosis writes "The CSIRO has unveiled new technology that could bring internet to people in rural or remote parts of Australia using their existing TV antennas. Analog TV signal is set to be switched off in 2013 but this technology could see the spectrum used to deliver internet straight into people's homes through their TV antenna. Gartner expert Robin Simpson told ZDNet Australia that this would make it much easier for companies to get new customers. 'What appeals to me about it is that it re-uses existing infrastructure, all of the competing wireless technologies tend to use high frequencies and therefore require new base stations, new spectrum and new receiving antenna infrastructure as well,' he said. 'The fact that they're re-using the analog TV stuff gives them a much easier market entry strategy.'"

Submission + - New compounds may treat both alcohol and cigarette

An anonymous reader writes: Researchers at the Ernest Gallo Clinic and Research Center at the University of California, San Francisco, and Pfizer Inc., have determined that two new compounds may be effective in treating both alcohol and nicotine dependence at the same time. In a paper published in the November 3, 2010 issue of Neuropsychopharmacology, the researchers showed that alcohol consumption in rodents was significantly decreased by two compounds that target neuronal nicotinic acetylcholine receptor (nAChR) subtype 3 4*. nAChRs are proteins found in the brain and broader central nervous system that mediate the effects of substances such as nicotine. Recent human genetic studies have shown that the genes encoding the 3 4* subtype are of significant importance for susceptibility to both alcohol and nicotine dependence.

Submission + - USB stick for Techs 1

SmoothBreaker writes: Slashdot readers, I'm working on a project for both my own company and my current full time employer, where we will have a usb stick loaded with apps and utilities to be used on systems to set parameters, troubleshoot, etc. However, the desired level of control is to restrict the drive to write permissions and allow the programs to run, but require only certain users to delete data from them, to prevent accidental deletions of the files and yet be ubiquitous across user machines and any domain. I havent found anything that seems to quite address that level of control. Am I missing a good solution, or is this only a pipe dream?
