  1. Re:Choice to Make on Cellphone Radiation May Protect Brain From Alzheimers · · Score: 1

    Actually, EM radiation is also composed of photons, which are particles. Nuclear radiation is mostly made up of alpha particles (helium nuclei), beta particles (plain electrons) and gamma radiation (electromagnetic photons, which just happen to have a very high energy and frequency so they look more like tiny bullets than like EM waves). X rays are also electromagnetic ionizing radiation, as are UV rays (which are close to visible mind you, and also cancer-causing).

  2. Re:In a way I blame certain scientists on The LHC, Black Holes, and the Law · · Score: 3, Informative

    Electrons and quarks are NOT singularities, they're described by wave equations. They're not balls or points or anything like that either. They are "spread out" in space and time if you will. Only because they have significant momentum due to thermal motion, their spread is so small they look like points. If you cool them down to fractions of a kelvin you get Bose-Einstein condensates that actually do look like waves.

  3. what real deal? on USB 3.0 the Real Deal, SATA 6GB Not Yet · · Score: 5, Insightful

    From what I can see in the graphs the USB3 HDD is indeed faster than on USB2 because of the bandwith; the SATA HDD is about the same on SATA 2 and 3, but also pretty near USB3. The title is implying superiority of USB over SATA when clearly the HDD is the limiting factor.

  4. Re:Analog Blog on The Monrovian Analog Blogger · · Score: 1

    Analog means that a voltage or current is analogous to another physical quantity, therefore the term analog computer (google it). For instance the voltage in a circuit is analogous to the pressure in your voice -- hence analog recording and processing. It can also be applied for non-electrical parameters -- the depth/width of the groove in a vinyl record for instance. You can also build pneumatic PID industrial process controllers -- they used to have those some decades ago -- those are analog machines, though not electronic. Of course you could also sigma-delta modulate the voice and record it as a stream of pulses -- it's still analog, the pulse density is the analog of the voice pressure. Once you throw in a clock and convert the pulse stream into multi-bit words and add and shift them in a FIR filter, then you're digital. Yes, you can say that analog is the oposite of digital, since there are no other means of processing and storing information that exist yet (or that I know of at least).

  5. Re:13 percent? on Chinese Gov't Pushing Linux In Rural China With Subsidies · · Score: 1

    I'm not quite sure what value to assign to an oppressive government's software either.

    Does the computer allow one to erase said software and install a clean distribution? If so, I see no fundamental problem. True, I don't expect many peasants to do that, if not because of the necessary technical skills, then because of their having better things to do such as caring for their crops. On the other hand, does its BIOS include a hidden hypervisor/backdoor? Is monitoring software included, that once erased, ceases to report the user's activities to the government, prompting repressive action? If not, again, I see no fundamental problem, but I see how this can help people manage their business better and also promote free software.

  6. Re:125 MORE years until the US gets time... on 125 Years of Longitude 0 0' 00" At Greenwich · · Score: 3, Interesting

    ISO 8601 doesn't favor the US or the other notation.

  7. False positives on Computer-Based System To Crack Down On Casino Card Counters · · Score: 4, Insightful

    Do they say something about the reliability of the method? Percentage of false positives? Those can mean angry customers and lost business.

  8. Data management problem on Getting Students To Think At Internet Scale · · Score: 5, Insightful

    Science has always been about extracting knowledge from thoughtfully-generated and -processed data. Managing enormous datasets is not science per se, it's computer engineering. It's useless to say 'hey I'm processing 30 TB' if you're processing them wrong. Scientific method and principles are what count, and they don't change.

  9. Re:Sweet! on Court Rules For Software Ownership Over Licensing · · Score: 0

    I don't know, if I buy a book I can't legally make photocopies of it and distribute them, or make derivative works or whatever; I guess its content is "licensed not sold" to me; its paper would be just like the CD that carries the licensed software. Despite this, I've yet to see any book that includes a license agreement. Why should software be different.

  11. Re:Herd immunity on Microsoft Blocks Pirates From Security Essentials Software · · Score: 1

    In the case of computers the herd is the whole Internet and distances between nodes are not measured in miles. You can measure them in number of hops or whatever, but from the software's standpoint they're really short and equal.

    Piracy is the distribution of copyrighted material for free

    No, piracy is an aggressive act committed on the high seas. Calling data duplication piracy is like calling 20km/h over the speed limit rape or murder. While that is expected from the *AAs, we shouldn't be feeding such exaggerations.
