  1. Re:We'll never know. on The Dusty Concern for the Mission to Mars · · Score: 3, Informative
    Unfortunately, this is totally wrong. PCR detection studies (just try to copy all DNA found and then sequence it) finds lots of sequences from non-cultured organisms no matter where we try to do it, in the human colon, in soil, in ocean water. This could mean that they are rather slow-growing or some other aspects that would make them more benign, but the overall argument against the invasion from Mars is the simple observation that life on Earth has been going on for a long time in very hostile combinations. The chance that foreign life would somehow know a "backdoor" by chance seems remote.

    (In that case, I would be more concerned about the effects on us when opening access to closed underground lakes on Earth, but those are still also far more susceptible to being destroyed by "our" biological environment, not the other way round.)

  2. Re:Sounds great in some respects. on Secretly Monopolizing the CPU Without Being Root · · Score: 2, Informative

    It works by sleeping at the right point in time. You really hack up the timeslices and decrease the overall efficiency (more context switches), so it's only good if you want to steal cycles where you are not really allowed to.

  3. Re:pi on Text Compressor 1% Away From AI Threshold · · Score: 1

    It's not true for all irrational numbers, but it is true for pi (and others). Anyway, this won't help you compress it. You need to store the index of the sequence inside pi, and it's quite obvious that a binary encoding of that index will easily get longer than the original sequence!

  4. Re:I call BS on MS Moves R&D To Canada Due To Immigration Problem · · Score: 1

    That's generally after completing the master degree first (although the technical requirement is a bachelor). It should also be said that technically not everyone gets the "real deal" with pension benefits and so on, but mostly anyone within engineering. The situation can be worse in for example biology in some places, and it's totally different in the social sciences. There has been some real controversy around Chinese PhD students coming on grants from their government and not getting any of this, but only a scholarship pay comparable to the amount of the Swedish student loan system for undergrads. The universities were happy of course, pick and choose engineering students and get them on the cheap...

    OTOH, it's not like Google isn't expanding heavily on R&D in just about any non-US territory (while also expanding in the U.S.). Immigration is one issue, preferences of possible recruit another. Financial reasons are of course also important, but Zurich isn't exactly the typical place for dirt-cheap outsourcing.

  6. Re:Both right? on The Impossibility of Colonizing the Galaxy · · Score: 1

    The black hole case is also quite evident from a theoretical standpoint, divide by zero never bodes well for a theory. We would expect the need to do more experiments there, from a purely theoretical standpoint. Not so with any arbitrary deviation.

  7. Re:How is this different from existing voice recog on Microsoft's Acoustic Caller ID Patent · · Score: 1

    There are existing voice recognition systems as well. Some are used to choose which speech recognition profile to use, while some are used for other applications, similar to the one in the patent.

  8. Re:error correction on Human Genome More Like a Functional Network · · Score: 1

    It's also fully possible that it's more a result of the opposite: the processes that tend to enlarge the genome have ALSO given us a rich variation in the gene pool, facilitating adaptation. The selection isn't made for large genomes, it's made for useful genes. The cost of a large genome alone is minimal, so it tends to keep growing until we have some specific bottleneck or disastrous effects where things might be thrown out on a major scale.

  9. Re:error correction on Human Genome More Like a Functional Network · · Score: 4, Insightful
    Genome space is damn cheap, just like disk space. The added tax on each cell to carry bloat is minimal. No matter how much is transcripted, we can analyze the sequences that we do see in the "junk". They are often very repetitive, with some sequences clearly deriving from viruses that integrate into the genome. The added selectional advantage of having the same (possibly now suppressed, but originally pathological) sequence, over and over, should be quite small, and the pattern and frequency of changes seems to indicate that most of these regions do not undergo any directed selection, i.e. mutations that do appear are kept at random, indicating "no value".

    We have this huge disk, and most of it is malware or free space. The results in RTFA are interesting, but the general idea that we can measure the frequency of changes and statistically determine whether evolution is working on a specific sequence, should still be sound, so if they are indeed used, it is probably in a far less sequence-sensitive context (sometimes overall folds, sometimes just stochastic effects from the whole pool of junk transcripts affecting the balance in the nucleus).

  16. Re:From TF Intel.com on Microsoft, Sony Clash Over Vista Turbo Memory · · Score: 1

    The thing in supporting Turbo Memory is that "proper" detection of what should be put there is no binary feature. It's obvious that it can be done in a more or less efficient way. It's kind of like regenerative braking in hybrid cars, to keep your analogy. You can have it, but think that the mileage advantage is too low, maybe even low enough to indicate that there is something wrong in the design of the system. As long as there is actual some juice coming from those breaks when the car slows down, it's hard to argue that the function would be missing, though.

  17. Re:Turbo Memory is... on No Intel Turbo Memory for Desktops Until Next Year · · Score: 1
    Another aspect is write caching. Imagine an idle machine churning out tiny registry writes (ok, blame it on the OS), or a moderately used http or db server where you still want complete logging and fs journaling. With this technology, the HD could spin down, and you would still be able to write to the filesystem and know that the things you put there, stay there. It touches on the hibernate issue, but I think the promise of possibly turning of the single remaining spindle in my machine is quite interesting.

    Before anyone screams about the number of writes, note what I am saying here: it's not for situations of heavy swapping, but just the case when a few writes are done. With 2 or 4 GB of RAM, I would even bet that the actual writes done under several scenarios of normal desktop use are really limited. Sure, filemon will spew out lots and lots, but count the actual number of sectors per second, and it sums up to almost nothing.

    One good thing with Santa Rosa is that, while the bus is 800 MHz (ok 200 MHz quad-pumped), Speedstep will affect the bus as well, scaling it down to 400 when relevant, making the chipset far less power hungry than the previous generation, on average.

    The amount of CO2 is about 300 ppm. Oxygen is about 20 %. (200000 ppm.) Even if all CO2 was removed and converted to elemental oxygen, we wouldn't suddenly self-ignite or be killed by free radicals. The lack of CO2 would make for a new ice age making the last few ones seem very meak, though.
