  1. Re:Already 44 times faster than needed. on Eben Upton Explains the Raspberry Pi Model A+'s Redesign · · Score: 1

    You mean: "44 times faster than needed, when all you want to do is USB control of relays"

  2. Re:the environment changes, the equation remains. on Study: Body Weight Heavily Influenced By Heritable Gut Microbes · · Score: 1

    total body weight is a function of caloric intake - caloric expenditure

    Ultimately yes, but there are still differences. Suppose you have two people with balanced caloric intake/output, then one person could be feeling fine, while the other is feeling like they're starving. Even worse, some people could actually physically starve, if incoming calories are all stored instead of being used by cells that require them.

  3. Re:Will it have the same garbage CPU? on Raspberry Pi A+ Details Leaked · · Score: 2

    It is garbage because a very closed CPU is used as an educational platform without datasheet availability.

    That would depend on what the education is about. If it's about teaching kids to program in Python, then the lack of datasheets is a non-issue. Even if you wanted to hack the Linux kernel, 90% of the code is architecture independent.

  4. Re:Down side on Raspberry Pi A+ Details Leaked · · Score: 1

    If the difference is just the SoC and not the core, it would be easy enough for Broadcom to produce an SoC with the same (or backwards compatible) peripherals, but with a newer ARM core.

  5. Re:Down side on Raspberry Pi A+ Details Leaked · · Score: 1

    the Pi doesn't handle raw pin I/O as nimble as a microcontroller.

    You can fix that with a kernel module.

  6. Re:Down side on Raspberry Pi A+ Details Leaked · · Score: 1

    It would have been nice if ARM had kept their improvements backward compatible.

  7. Re:Efficiency on There's No Such Thing As a General-Purpose Processor · · Score: 1

    Similarly, arbitrary cells in your body can't just run on fruit from trees. They need a very precisely regulated supply of certain substances, which needs to be regulated by very complex mechanisms in the body.

    Saying that the temperature will naturally go back down is also a climate model. And it also comes with a responsability.

    But moss and algae do respirate and excrete, even if they don't have stomata.

    No, there's no need for creatively redefine these terms. Plants do have respiration and excretion. Example: http://www.ncbi.nlm.nih.gov/pu... :

    During prolonged darkness, plants with low carbohydrate reserves exhibited a lower whole-plant respiration rate, which decreased rapidly to almost zero after 24 h, and carbohydrate pools were almost exhausted in leaves, roots and flowers

    The fact that Zuckerberg is CEO of a Fortune-500 company isn't a guarantee that he's any better at predicting the future.

    So if someone succeeds in building a living cell from scratch, you wouldn't consider it really alive ?

    The TCP checksum is only 16 bits, so there are plenty of errors that aren't caught.

  18. Re:Discover life? on Why Scientists Think Completely Unclassifiable and Undiscovered Life Forms Exist · · Score: 4, Interesting

    A self-reproducing system that does so perfectly, with no errors won't ever change, and isn't really alive.

    If it is successful at surviving, why would it need to adapt to be alive ? Maybe it's already perfectly adapted to its environment.

  19. Re:Discover life? on Why Scientists Think Completely Unclassifiable and Undiscovered Life Forms Exist · · Score: 1

    I would consider #6 reproduction the most crucial one. Growth, nutrition, respiration and excretion are basically requirements to get (sustained) reproduction, while movement and sensitivity aren't strictly needed.

  20. Re:Type 1 vs Type 2 on Human Clinical Trials To Begin On Drug That Reverses Diabetes In Animal Models · · Score: 1

    Body/mass index isn't necessarily a reliable indicator, though. Two people with identical weight and identical fat percentage can still differ in the place they carry the fat. Fat around internal organs can cause metabolic disorders, while the same amount of subcutaneous fat can be harmless.

  21. Re:Nothing? on Mathematical Proof That the Universe Could Come From Nothing · · Score: 3, Interesting

    Our brains were made for the 4 F's: fighting, fleeing, foraging and reproducing. Understanding of quantum mechanics was not a driving factor, so we just have to accept that we don't understand.

    Overlapping datasets are always good. Helps to catch mistakes, and helps to reduce error bars.

    Actually, Columbus thought he was taking a shortcut to India (but it was actually a detour). If not for the new world being in his way, he would have most likely starved before he got there. So much for assurance...

  25. Re:Old saying on New Atomic Clock Reaches the Boundaries of Timekeeping · · Score: 4, Informative

    Every GPS signal is the time...that's how it works.

    Obviously yes. But the signal you hear from each satellite is offset by an unknown amount (assuming unknown time/position). So, you need to solve for 4 variables (time, x, y, z), so you require 4 satellites, as you said later on. If you know 1 of the variables (for instance, because you have an accurate local clock, or you guesstimate the altitude), you can survive on 3 satellites, but it will be less accurate.

    Note that you need to know local time to nanosecond accuracy, so a regular quartz oscillator is only useful for a short time after synchronisation, and will drift away fairly quickly.
