  1. Re:Amazingly high pseudofield on 'Bizarre' Nanobubbles Found In Strained Graphene · · Score: 1

    "In other words the electrons must be at really high energy levels."

    Probably not, the most likely is that the electrons have very small orbitals.

    By the way, electrons on a conductor normaly have energy equivalent to a several thousand Kelvin Boltzman distribution, but that is still way lower than what you imply.

    Not to mention the PAL-M, PAL-N and NTSC incompatibilities, 300ohm/m, 220ohm/m and 120ohm/m (did I miss any?) cables each with an incompatible connector, and, since we are talking about connectors, the more recent RCA, component, DVI and HDMI choice.

    I'll tell you something, those rotating disks are EVIL! They are full of DRM, some disks even come with DRM enforced by non-standard shapes (and HOLES!) that will destroy your driver unless you use the hardware that comes with them.

    No, thanks, I'll stay with my cassete tapes, they only have DRM by the means of silence insertion that you can defeat by the right application of scisors and adesive tape. Now go away while I backup my next 200KB of data.

    Just wow! Just for $499 you'll get 1,5m of cable that will give your system all the nuances of the DIGITAL audio. Surely some people don't know what digital means, but I wonder if it shouldn't be enough to send someone to jail.

    At least the gold ended optical fibers an AC posted on this thread has a clip, for helping you organize your cables! That's what I'd call usefull.

  5. Re:Error bars on Possible Room Temperature Superconductor Achieved · · Score: 1

    I missed them to, but to be fair, his setup wouldn't generate them easily. He could take the errors from the manual of his equipment, but I doubt they could be trusted on such a low currents, voltages and magnetic fields.

    That is the kind of setup that (physicists hate) you need to infer your error from the data, and only simple conclusions (like "it's a line") could be drawn. The fact that the measured resistence of one of the materials look like a senoid, with a negative part makes it even harder to belive

    Anyway, looks like some serious candidate for testing with proper equipment.

    "The vast majority of users are running either Ubuntu or Fedora."

    Or Susie, or plain Debian, or slackware. From the Distrowatcher, Debian based distros are the mos common, they are 1/3 of them. Of course, saying "Debian based" isn't enough information for an attacker (unless he targets synaptic, or should he target aptitude instead?), the most used is Ubuntu (all versions of it) with something near 20% of the instalations. So, the best you can target at is 1/5 of the population. Also, Ubuntu systems are mostly low profile, if you want to get the best computers, you'll have to go for Red Hat (the most used on that segment), and you'll discover that from the point of view of the attacker, one Red Hat install (or any distro on a hight profile system) differs way more from another HR install (even of the same version) than a Windows NT install differs from a Windows 2008 one.

    Anyway, diversity alone is not the end all explanation for Linux machines not being infected so often. Usability, bug count, the expertize of users and admins, and even the smaller number of instalations (on some segments) are also important.

  8. Not CYA, but optimal cost/benefit on Data Storage Capacity Mostly Wasted In Data Center · · Score: 1

    Did you factor in how expensive is it to change storage size, and the costs of failing to change it? Also, there is the cost of adding some storage that isn't compatible to the first chunk. The amount you pay for oversized storage normaly isn't even on the same order of magnitude of all of those.

  9. Re:Disk space is free on Data Storage Capacity Mostly Wasted In Data Center · · Score: 1

    Those virtual machines are stored on a real SAN somewhere. The SAN administrator deals with all the things the GP said, that is why you don't need to understand it. Anyway, he'd better have some spare capacity and plan based on I/O, and not storage size (he probably did), otherwise, you'll have big unknown risks.

  10. Re:Intentional? on Data Storage Capacity Mostly Wasted In Data Center · · Score: 1

    That's even not talking about the fragmentation that inexorably follows a project that has the exact needed size, and all the costs of managing it.

    If you are now using 60% of your storage capability, you are in troble since that can increase quite fast, not giving you time to buy adequate hardware. What follows is a hell of problems, partitioning storage servers, reallocating disks, reconfiguring workstations and so on.

  12. Re:Maybe it's as simple on A New Take On the Fermi Paradox · · Score: 1

    "I think it's fairly likely that there will not be too much variation in natural lifespan in space-faring races (+/-50%?)."

    That is a funny thing to say, since we have on earth species that survive for hundreds of years (and specimens that are more than 500 years old). There are also species for what it makes little sense to talk about age.

  13. Re: Maybe it's as simple on A New Take On the Fermi Paradox · · Score: 1

    The problem with that thinking is that it just need one species, in the entire galaxy to want to spread. Then in a very short time, the galaxy would be completely colonized. If inteligent life is plenty out there, it is quite hard to assume that no species at all (including non-inteligent ones that could develop due to space exploration of the inteligent ones) wants to spread.

    And aways remember that the Sun is a very young star. If intelligent life is plenty it should have started spreading before the Sun even came to existence. So something is wrong here.

    That's not bad brading, that is part of the game. Phone manufacturers want to make their phones unique, and Google designed and licensed (maybe without intention, but did so anyway) Android in a way that they can do it. That is part of what is making it popular.

    So, they'll write a Windows for the ARM? And where will they use that core?

    I'd bet they want it to their periferals, that just make a lot more sense. With that IP, they can design custom chips for them and reduce costs or increase functionality beyhond what their competitors are able to.

    Well, you really don't want to run molten NaCl (or any other Cl, I of F salt) inside metal pipes. They can't be using carbonates, since you can't heat them that much. Sulfates are also too agresive, so they probably are using nitrates (altough I'd put a just a bit of a weak hidroxide in the mix).

    We've decided we can do it because every time we simulated those conditions in lab, we got the right answers.
