  1. Re:How can you tell? on Underground Lab To Probe Ratio of Matter To Antimatter · · Score: 1

    I meant electron-positron annihilation, of course. My brain had "proton-antiproton" in its head when I wrote that, and so it came out weird.

  2. Re:How can you tell? on Underground Lab To Probe Ratio of Matter To Antimatter · · Score: 3, Informative

    I thought it wasn't possible to tell antimatter from matter from afar?

    In a perfect vacuum, it isn't. However, even the intergalactic medium isn't a perfect vacuum, and somewhere there would have to be a border between a matter region and an antimatter region. Such a region would give off a very specific gamma ray spectrum, with a peak at 511 keV due to positron-antipositron annihilation and several peaks in the 70-400 MeV range due to proton-antiproton annihilation; the rate of interaction would be low, but the surface area of the frontier so large that we should be able to observe it from Earth. If it is a more localized phenomenon (like Niven's star system), then it would be travelling through the interstellar medium, inside a galaxy, which is far denser.

  3. Re:Aliens Cause Global Warming on Number of ET Civilizations In Our Galaxy Is 37,964 · · Score: 4, Interesting

    But the equation is trivially true; it's nearly a tautology.

    Not quite. It implicitly presupposes a steady-state universe, which was commonly believed at the time. However, we now know that the universe is not steady-state, and in fact is quite young (13.7 Gy) compared to the age of the Earth (4.55 Gy). Especially if the conditions in the Universe have been shifting, e.g. it has taken time for stars to build up enough metallicity, it is entirely plausible that conditions may be hospitable to life, and yet it is not common, simply because we just got there first. This is particularly important if you accept the conclusions of the Fermi Paradox, which basically states that since technological advancement is so rapid compared to evolution, the first technological civilization in a galaxy will almost inevitably colonize the galaxy before any other civilization has had time to evolve.

  4. Higher temp = higher power on Google Demands Higher Chip Temps From Intel · · Score: 1

    I have to say I am a bit surprised. A CPU operating at a higher temperature will draw more power and thus produce more heat at the same performance point. This is one of many temperature dependencies in silicon circuits. Now, it's possible that Google's demand is that they can run at the same speed and power at the higher temperature, which means in reality they are underclocking a faster chip to run it warmer.

  5. /tmp on tmpfs and large swap on How Big Should My Swap Partition Be? · · Score: 2, Insightful

    I personally prefer to put /tmp on tmpfs, and combine with a large swap partition (much larger than 2x RAM). tmpfs is a lot faster than a regular filesystem *even if it has to hit disk*, simply because it doesn't have to care about consistency. If the machine goes down, the data disappears.

  6. Re:Coke Cola and Pepsi on AMD Employee Charged With Stealing Intel Secrets · · Score: 1

    AMD has had a fair number of people trying to sell them Intel trade secrets over the years (at least one who made a video tape of his workstation screen.) They have consistently responded by contacting the police, and at least once cooperated with a police sting operation for the intended "drop".

  8. Re:ever fill out a tax form? on Real-World 3G Monthly Cost With Taxes and Fees? · · Score: 1

    Figuring out the taxes on a phone line is rather complimakated, difficult enough that providers have made mistakes on it in the past and had to refund overcharges or eat the difference in undercharges. I'm not surprised that the salespeople don't know, and I'd bet nobody on phone support will know either.

    They don't know, because corporate doesn't want them to know either how to do it, or for that matter, the result. They're supposed to make it as hard as possible to compare prices.

  9. Re:Move on Satellite Internet Providers · · Score: 1

    Satellite internet service has latency issues that will NEVER go away. It's the speed of light that is the limiting factor. I'm surprised you were able to use VoIP at all, honestly.

    You know... satellite used to be the only option for intercontinental phone calls, too. It wasn't until the late 80's that undersea fiber cables finally dominated that market.

    There is, of course, a perceptible lag, but it's perfectly serviceable.

  10. Re:mm on In Iran, Blogging May Be Punishable By Death · · Score: 3, Insightful

    Non-separation of church and state is not necessarily bad but most (if not all) "states" which do not have the separation are also dictatorships therefore giving non-separation movements a bad connotation.

    The question is whether or not this is a casual relationship. Given that the elements in the USA which seem to be the ones advocating chipping down this barrier even just a little bit pretty much want to do that to other civil rights, I think there probably is. Religion, ultimately, wants to base its existence on "things are this way because we said so", which is ultimately incompatible with human-centric, rational governance.

    No argument, of course, about USA versus Iran. We're talking level 2 versus level 100000. The Iranian theocracy are nothing but a bunch of murdering thugs.

  12. Re:No, he's talking about replacing TCP/IP. on Net Neutrality vs. Technical Reality · · Score: 1

    Well, Wi-Fi (IEEE 802.11) isn't really Ethernet (IEEE 802.3) and is CSMA/CA rather than CSMA/CD (carrier detection requires a guarantee that all nodes can hear each other even when the node itself is transmitting.) However, they do have similar degradation behaviour in the presence of traffic, of course. What I said was true with regards to wired Ethernet links, however.

  13. Re:No, he's talking about replacing TCP/IP. on Net Neutrality vs. Technical Reality · · Score: 2, Informative

    It's particularly ridiculous to talk about how increasing bandwidth will not solve problems in the face of Ethernet, which has consistently beaten off all other comers by piling on the bandwidth even though its link utilisation is piss-poor...

    Ancient history. Very few Ethernet links today are CSMA/CD. Full duplex Ethernet is simply a point-to-point serial link which has no utilization degradation, and since switches replaced hubs, virtually all Ethernet links are full duplex.

  14. Nooklear Wessels on Japanese Company Says Laws of Physics Don't Apply — to Cars · · Score: 4, Informative
    Okay, this is starting to piss me off, because I have now seen posts on Slashdot that gets this elementary thing wrong both ways...

    There is exactly one way by which you can make hydrogen extraction from water a net power gain: if the hydrogen extracted is used for nuclear fusion. Assuming any remotely efficient fusion (i.e. worth bothering with), the energy gain from fusion should vastly exceed the cost of splicing water, separating out deuterium, etc. For combustion in oxygen, no... water is already the ash of that process.

    You could theoretically burn hydrogen in a fluorine atmosphere and get more energy out, but that assumes a ready supply of elemental fluorine (doesn't exist) and something to do with the hydrogen fluoride that results (HF will corrode glass.)

  17. Directional antennas on Parent-Friendly Wireless Bridge To Span 500 Meters? · · Score: 1

    Ordinary Wifi can easily go for quite a few kilometers if equipped with directional antennas (usually Yagis, what most people think of as "TV antennas") at both ends. If you get custom firmware such as DD-WRT for ordinary access points you can usually crank up the power closer to 100 mW (WRT54GL tops out around 80 mW from what I've read.) The legal limit in the USA at least is 1 W, so if you can get your hands on an access point with an amplifier (Belkin used to make them.)

    The best of all is that the total solution ends up being pretty cheap. You *do* need line of sight between the antennas, however.

    I would get an HP DL360 series machine off eBay, at whatever generation you happen to need (G2 should be OK given your specs.) They are quite inexpensive by now, *very* well built, and remote-manageable. The downside is they take only SCSI disks, which would be a problem if you need more than a few tens of gigabytes of storage, but if you can spare a second U you can buy an inexpensive eSATA enclosure and put in an eSATA card in the machine.

    We KNOW he's breaking the law, but who's going to be the one who stands up to throw the first stone? So far, no one's doing it.

    Actually, quite a few are stepping up (including the ACLU), but with half the population believing the propaganda wing of the Republican Party, a.k.a. Fox News, is actually a news source, it's hard to get through to enough people to make a difference. At this point, the best bet is pretty much to make him do as little damage as possible before he gets thrown out. He certainly has lost any momentum toward eliminating the XXII Amendment, which was floated several times in the 2001-2003 timeframe.
