Open-Source or FIPS-Validated Disk Encryption? 74

j_crane asks: "Our company is looking for disk encryption software that runs on Windows XP/2003 and Linux. There are hundreds of commercial disk encryption programs (most are Windows-only though). Some of them are FIPS-validated by the US NIST, but none of these are open-source. On the other hand, there is an excellent open-source on-the-fly disk encryption software, called TrueCrypt, for Windows and Linux (the program even provides plausible deniability), but it does not have a FIPS-validation. Which would you prefer -- open source or FIPS-validated -- and why?"

Reverse Multithreading CPUs 263

microbee writes "The register is reporting that AMD is researching a new CPU technology called 'reverse multithreading', which essentially does the opposite of hyperthreading in that it presents multiple cores to the OS as a single-core processor." From the article: "The technology is aimed at the next architecture after K8, according to a purported company mole cited by French-language site x86 Secret. It's well known that two CPUs - whether two separate processors or two cores on the same die - don't generate, clock for clock, double the performance of a single CPU. However, by making the CPU once again appear as a single logical processor, AMD is claimed to believe it may be able to double the single-chip performance with a two-core chip or provide quadruple the performance with a quad-core processor."

Earth Life Possibly Could Reach Titan 237

dylanduck writes "New simulations show that big asteroid impacts on Earth could have sent about 600 million boulders flying into space. About 100 have reached Jupiter's moon Europa - but they landed at 24 miles/sec. 'This must be rather frustrating if you're a bacterium that survived launch from Earth,' says a researcher. But 30 boulders from each impact reach Titan - and they land gently." From the article: "'I thought the Titan result was really surprising - how many would get there and how slowly they'd land,' Treiman told New Scientist. 'The thing I don't know about is if there are any bugs on Earth that would be happy living on Titan.' Titan's surface temperature is a very cold -179C and its chemistry is very different from Earth's."
