  1. Re:750,000 hours MTBF. on 3TB Hard Drive Round Up · · Score: 1

    Interesting. I hadn't realized any of the native implementations had progressed so far, and trying to run something like ZFS through FUSE just seems disastrous. I'll have to look into this. Right now, I've got several Gentoo systems booting off iSCSI JFS disks, served from cloned ZFS volumes on a FreeBSD server. It would be useful if the images were formatted with a filesystem the server could actually read.

  2. Re:I don't trust my data to a single huge drive on 3TB Hard Drive Round Up · · Score: 1

    The claims that newer drives are more error prone is a fallacy, resulting from a failure to understand basic statistics. These are people who in the past have bought one, maybe two hard drives, but now they have several OS drives on several computers, plus several more for bulk storage, portable storage, etc. When you have five times the number of drives, you are five times more likely to suffer a failure in one of them. People are experiencing more failures, because there is more to fail, and they are incorrectly equating that to a belief about reliability.

    L2ARC in ZFS was released over three years ago, in mid-2008. I figured such a capability would have shown up in one of the big storage manufacturers before that.

    Commercial SANs have had such tiered capability for years. Multiple levels of performance from bulk, long term storage on spinning disks to short term storage on SLC flash and finally a big memory cache. ZFS for Solaris and FreeBSD offers something similar with the L2ARC, allowing a cheaper but slower way to provide a large, high speed memory cache.

    If you know precisely the direction the observer is looking from, and there is only one observer, such that you could make something optically "invisible" by projecting an image onto it, why not just kill the observer?

    We spend, I think, 7 times more on military pieces parts THAN THE ENTIRE REST OF THE WORLD COMBINED

    Not anywhere close. The US spends as much on military as the next 15-20 countries combined. They spend a little less than the rest of the world combined. If you look at it from the other direction, they spend around 4.5% of their GDP on military. The global average for spending is around 2.5-3%. Russia spends around 4%. Middle Eastern countries spend 5-10%.

    Does the US spend a lot on military? Undoubtedly. Is that spending a bit high? Perhaps. Is that spending ridiculous and out of control? Not at all.

    Were talking about graphics . The graphics on the current Llano chips are bottlenecked because the memory interface is too slow, and there is insufficient local cache available to compensate. The Bulldozer architecture will bring modest increases in memory bandwidth and cache, but that will be offset by a more powerful CPU to share the resources with. Thus Bulldozer will not bring any improved graphics on top of what the existing systems have. The server variants of Bulldozer will have double the memory channels for double the throughput, but they will only be used in systems where the performance of integrated graphics is not of concern.

    Because the concept of regenerative braking has been around long before the Prius was a twinkle in Toyota's eye. Bringing them into this, alluding that they invented it, is what makes you sound like a troll.

  18. Re:Isn't this an old idea? on Tapping Subway Trains For Energy · · Score: 3, Informative

    They're talking about the latter. Subway systems run an electrified third rail, charged with somewhere between 500-1500VDC. Trains draw power off this rail as needed, and power substations are located periodically throughout the system to supply it with power. They're talking about using the traction motors to stop, instead of brakes, and pumping that power back into the DC rail. Then setting up flywheels attached to the power substations that intelligently buffer the power supplied to the rail.

    When the train brakes and dumps power onto the rail, the flywheel sucks it up. When the train wants to take off again, it is powered by the stored energy in the flywheel. Due to the low rolling resistance of metal wheels, trains require surprisingly little power to operate. Between the energy capture efficiency, and low operating needs, such a subway would run on only a small fraction of its current draw.

    The Atom was a quick and dirty way for Intel to get into the tablet and netbook business as that market was taking off. It's only reason for existence is that it is an x86 processor, and thus can run Windows. Except to see sales drop off rapidly when Windows 8 comes out with ARM support.

    Llamo, on the otherhand has much better graphics compared to an Intel atom .. to hell even a full speed i5! Bulldozer will have even better graphics. If you just run IE 9/10, flash, and Office the AMD llamo and bulldozer will seem faster and less choppy. They can also run games like World of Warcraft as well. Sub notebooks sucks and can do these things and run these games.

    Llano has much better graphics than Intel's offerings, too good in fact. They stuffed in far more performance than has ever been seen on an embedded GPU, and bottlenecked it severely on the CPU's memory bus. It can't run full speed. It can't even run half speed without running into bandwidth limits. There is good reason why its discrete brethren are reaching into the triple digits. All they're doing is sucking down more power and real estate on silicon that can't be properly used.

    Bulldozer won't change anything. The desktop systems get a modest increase in supported memory frequency, but now you're sharing that memory bus with a more powerful CPU. The workstation and server grade processors have double the memory channels, but people who buy those couldn't care less about onboard graphics. Those chips are either going into a server rack, where all you need is something that can drive a monitor, or workstations, where you're going to pair it with a proper discrete graphics card.

  21. Re:Decent Computer? on Building 2011's Sub-$200 Computer · · Score: 2

    1) Itunes - sure there are plenty of great media players and what not for linux... but if you have an ios device whether its a new ipod, ipod touch, iphone, or ipad (and literally tens of millions of completely normal people do, they need itunes).

    My dad uses Winamp to sync his iPod. He wants to manage his music the way he wants to do it, and not the way Apple tells him to do it. Now granted, Winamp is Windows software, and while I don't know of or care to find similar software for Linux, saying it requires iTunes is false.

    2) TurboTax etc... yep its just one week a year. But millions of completely ordinary people do their taxes with this type of software.

    TurboTax doesn't do anything particularly funky with respect to Windows. I see no reason why this couldn't run on WINE. You could argue that most people would have no clue how to run an application through WINE. You could also argue that it's trivial to learn to just prepend 'wine' to the command line, and not much more difficult to make an icon in gnome/kde to do so.

    3) Miscellaneous Toys - from the child friendly Barbie photo manipulation software that came with the Barbie camera to setting up your new Logitech universal remote to an AppleTV to programming a Lego Mindstorms creation with LabView.

    Lego RCX units and Harmony remotes can be programmed on Linux using 3rd party software. Technically, Harmony remotes are programmed on the Logitech servers, through a web application, and the only thing the software is used for is to transfer the profile to the device. LabVIEW offers OSX and Linux versions of all but their bottom end interfaces, and what is someone doing worrying about a $200 computer when they're going to use it to interface with IO boards that start at that price and go way way up? The AppleTV is itself a computer, capable of accessing the iTunes store directly. It has no need for interaction with a PC. If you're talking about streaming content to it, well then there are mechanisms for doing that in Linux too.

    4) Video games - Believe it or not, lots of perfectly normal people play everything from World of Warcraft,to Left4Dead, to the copy of Bejeweled or Riven they picked up at Walmart for $7 as an impulse buy.

    A quick check puts some 5000 games and applications on the Platinum and Gold compatibility list for WINE. Yes, people will be afraid of things like WINE, but suck it up and put out a little effort if you want to avoid that $100 Windows OEM license. WOW, L4D, and Bejeweled are all on the Platinum list, meaning it works perfectly out-of-the-box with no special configuration.

    5) Peripherals - Printer fax scanner copier combination devices in particular still suck with linux. Getting printing going is usually relatively straightforward, but anything else is a complicated crapshoot.

    I can't speak to other print companies but HP offers the HPLIP drivers, with support for some 2000 different pieces of hardware. Using it, I had absolutely no trouble getting printing or scanning working on my all-in-one unit.

    There is no such thing as a "suitcase nuclear reactor", going by the definition that a reactor requires criticality. These small devices are called RTGs, or radioisotope thermoelectric generators. It is a chunk of radioactive material surrounded by a Seeback layer. The radioactive material decays, giving off heat, which escapes through the thermoelectric layer, producing power through the Seeback effect. These things are solid state, and designed to release power on the order of a few hundred Watts, to a few kW, for decades. They can be, and are, built like tanks. They will survive a detonation on launch, re-entry from a failed orbit, and hours of sitting in a pool of burning fuel.

    Private aircraft would need power outputs on the scale of a hundred kW. Private jets would need power output on the scale of a few MW. Commercial airliners would need power output on the scale of a few hundred MW. They need to be full fledged fission/fusion reactors, pumping out large amounts of power, and extremely light weight. All of this leads toward a system that cannot provide sufficient shielding during normal operation, and durability during a crash.
