  1. Re:Interesting but... on Raspberry Pi $25 PC Goes Into Alpha Production · · Score: 1

    Add an ADC, an DAC and a few binnary I/O ports and you can have an alarm/garage controler, but to have a PC like we define it now, you'll only need to add networking.

    I think calling it a PC streches a little less the definitions.

  2. Re:Once you have discovered on Why Your Dad's 30-Year-Old Stereo Sounds Better Than Yours · · Score: 1

    Most subwoofers are:

    1 - Too light. That creates distortion at loud volumes because they vibrate.

    2 - Too smal. Small frequencies need large plates, and modern subwoofers have the radius of things that were called tweeters just 20 years ago.

    3 - Useless if your amplifier doesn't have enough power to move them. What is mostly the case nowadays.

    "There is no substitute for mass. (this is a favorite saying of mine)"

    That is, at the power end. At the pre-amp modern circuits evolved a lot from 30 years ago, and digital signals have a clear advantaje over analog disks. None of that makes you wrong, but it made you sound wrong as a first impression, just because you didn't specify the scope.

    Well, I guess that rule doen't apply to trojan points. Otherwise the list of planes would be quite small (4 now, but may quite well setle in 1 - Mercury - or 0 when we get better telescopes).

    "the Tea Party is particularly dangerous because they seem to want a default"

    Yeah, and they may be right. Maybe a default is the best course of action for you.

    Ok, the best course of action would be to cut the deficity and start paying the debt. That is a certainty. Assuming that isn't policaly possible (a big assumption), a default is probably the best possible alternative.

    There are only two problems with that. One is that the site does not have a search engine. The second one is that google will include the site at its results, and I bet that even if the site does implement search, google's will stil be better.

  11. Re:No FTL == No time travel? on Single Photons Do Not Exceed the Speed of Light · · Score: 1

    Relativity* being true, any way to FTL travel breaks causality for some reference frame.

    Independently of relativity, any way to break causality will make data travel faster than light on at least one reference frame (if you allow relativity, several reference frames).

    No shorcuts, or side approachs. If relativity is true, both concepts are equivalent.

    * Any kind of relativity coherent with the Maxell Equations. Ok, I only know about one example, but it is nice to state the requirements clearly.

  12. Re:Nonsense on Single Photons Do Not Exceed the Speed of Light · · Score: 1

    If you have FTL and relativity (doesn't need to be General Relativity, or even Eistein's Special Relativity, it just needs to be any kind of relativity coherent with Maxell equations) there are reference frames where that FTL particles reaches its destinations before living its origin. That is what the GP is trying to say.

    We suddenly discovering that General Relativity is wrong won't change that picture, as the time and simultaniety dependence on reference frames are "big" phenomena from GR, the time dependence being tested on practice (and enough to imply the simultaniety dependence).

    PC users needed the floppy because lots of proprietary software came only ono floppies or needed them to install. Also, there was the issue of "talking" to that older computer that couldn't read writable CDs (not all computers were on a network by the time), and that the writtable CDs were way more expensive than floppies.

    Cheap as the drivers were, it simply made no sense to not have them.

  17. Re:I've Got a Question on Has LHC Seen a Hint of the Higgs? · · Score: 1

    "For instance, nobody working on Quantum Mechanics early last century would have had any clue whatsoever that this would enable the computer revolution."

    Most of the applications of quantum mechanics were quite evident at the moment the theory was created. Specificaly computers were already available for a long time when solid state physics came out, and they were one of the obvious applications of the transistor, that was one of the obvious application of the theory (that is, of course, after the theory was created).

    I'm not holding my breath for applications of the discovery of the Higgs' bosson. The discovery that it doesn't exist, otherwise, may be very interesting.

    That said, it was just a 2.8 sigma event. Well, what are the odds of nobody seeing an expurious 2.8 sigma even up to now?

    Kelvin Mega what?

    On a side note, I know plenty of people that use the SI as if it was case insensitive. Other common bastardizations:

    Caling the unit "linear metter", and abreviating it as "ml" (in latin languages of course, english speaking people are more likely to use some custom unit for that)(again, propably case insensitive, so replace it by Ml, mL or ML if you like).

    Abreviating second as "sec", square metter as "sqm" or "quadm", "mqd", etc.
