  1. Say what?!? on Japan's Petaflop Supercomputer · · Score: 2, Informative


    Japan has managed to create the first Petaflop supercomputer, called MDGrape-3, with just 4808 chips...

    FLOP = floating operation [per second].

    PETA = 10 ^ 15, or "a quadrillion".

    (10 ^ 15) / 4808 = about 207,986,688,852, which would indicate that each chip is running at several hundred TERA-hertz [and, even then, the machine would have to possess an operating system so efficient that it could consistently perform one floating point operation per clock increment, which seems extraordinarily unlikely].

    Or is this an "analog" computer and are these "analog" FLOPS?

    And no, I did not RTFA.

    Anonymous Coward: The Xbox is almost a certainty to get the axe

    The X-Box is their most innovative "rip-off" since at least Active Directory. They've sold 5 million units, and they think that, with Sony's delay in transitioning to the Cell processor, they can sell 15 million more in the next year. The gross revenues for the XBox alone are pretty much equal to [or even exceed] the gross revenues of Novell and Red Hat COMBINED.

    Have you ever watched a boy [or even grown men, with professional degrees, like MDs, JDs, PhDs, etc] playing a video game? The stuff is utterly addictive. M$FT giving up the video game market would be like RJ Reynolds or Philip Morris giving up the cigarette market - it's a guaranteed revenue stream from now until the end of time.

    In fact, in twenty or thirty years, I can see the various state Attorneys General suing M$FT, just like they sued the tobacco companies, in a massive class action law suit, on behalf of all those l00s3rs who wasted their lives away on that nonsense.

    The XBox division might be bleeding red ink right now, but good grief, long term it has the potential to be phenomenally lucrative.

  3. No, it's slave labor. on $5000 Award for Open Source CMS · · Score: 1


    Actually, it's worse than slave labor. A slave master has to feed and clothe his slaves, and keep a roof over their heads.

    In the real world, an enterprise-worthy CMS might cost easily several million in upfront R&D [anywhere from 10 to 50 man-years worth of labor, just to get to the "alpha" stage, with a total compensation package of easily $200,000 per man per year], and that's before you start regression testing and then moving to something you might call a "beta" version.

    $5,000 is roughly what one contract programmer would cost for a WEEK. A week isn't even enough time to start making your stupid little "object note cards" [yeah, I'm dating myself]. Hell, a week isn't even enough time to start drawing stupid pictures on the whiteboard with the dry-erase markers.

All this is facilitated by the 9p protocol [bell-labs.com].

    This sounds remarkably similar to what Richard Stallman's The Hurd was supposed to be. [Speaking of which - Duke Nuke'em Forever ain't got nothing on The Hurd.]

    The first hit I got was to this discussion from about three months ago:

    Convert CDR to AI or EPS

And then either mail me the file on a CD-ROM, or upload the file to a site like RapidShare, and then email me a link to the uploaded file so that I can download it? Thanks!"

    2) I don't want to say "abandon the desktop", because you've got a history of interest & subsequent disinterest in the desktop going back more than a decade, to WordPerfect and Corel, but here's an idea that involves expansion beyond the desktop: Take a long, hard look at the embedded market.

    You're wrong. You can cypher it with the public key and it can't be recovered without the private key, which is safe at his computer.

    The system you've described is not [internally] closed - it requires interaction with an external agent [which, in theory, at least, means that the FBI/NSA can track the transaction and find the bad guy].

    Ideally, though, you would want this sort of thing to be closed [with the encryption & decryption entirely internal to the system itself].

    Now I'm not an expert in encryption [really hardly even a novice], but it's always seemed to me that there must be some meta-theorem in encryption theory which states that this is impossible - that an encrypted system which is capable of de-encrypting itself is necessarily capable of being de-encrypted by a third party [with sufficient time and money on its hands].

    nVidia & IBM/Sony/Cell/Playstation can perform only 32-bit single-precision floating point calculations in hardware. [IBM/Sony can, at least in theory, perform 64-bit double-precision floating point calculations, but the implementation involves some weird software emulation thingamabob which invokes a massive performance penalty.]

    ATi is even worse - last I checked, they could perform only 24-bit "three-quarters"-precision floating point calculations in hardware.

    And just in case you aren't aware, 32-bit single-precision floats are essentially worthless for anyone doing even the simplest mathematical calculations; for instance, with 32-bit single-precision floats, integer granularity is lost at 2 ^ 24 = 16M, i.e.

    16777216 + 0 = 16777216
    16777216 + 1 = 16777216
    16777216 + 2 = 16777218

    Now while 64-bit double-precision floats [or "doubles"] are probably accurate enough for most financial calculations, where, generally speaking, accuracy is only needed to the nearest 1/100th [i.e. to the nearest cent], 64-bit doubles are still more or less worthless to the mathematician, physicist, and engineer.

    For instance, consider the work of Professor Kahan at UC-Berkeley:

    William Kahan
    In particular, read a few of these papers from the late nineties:
    PDF File: Roundoff Degrades an Idealized Cantilever
    PDF File: How JAVA's Floating-Point Hurts Everyone Everywhere
    PDF File: Matlab's Loss is Nobody's Gain
    At the time, Kahan was arguing in favor of using the full power of the Intel/AMD 80-bit extended precision doubles [i.e. embedding 64-bit doubles in an 80-bit space, performing calculations with the greater accuracy afforded therein, and then rounding the result back down to 64-bits and returning that as your answer], but, truth be told, the Sine Qua Non of hardware-based calculations is true 128-bit "quad-precision" floating point calculations as performed in hardware.

    Sun has a "quad-precision" floating point number for Solaris/SPARC, but, sadly, it's a software hack, and, like IBM/Sony/Cell/Playstation, far too slow to be used in practice.

    I believe that IBM makes a chip for the Z-Series mainframe, which can perform 128-bits in hardware, but I imagine that it's prohibitively expensive [if you could even convince IBM to sell it to you in the first place].

    The best configuration here would probably look like a fancy-schmantzy Digitial Signal Processor [DSP] chipset, from someone like Texas Instruments, capable of 128-bit hardware calculations, mounted onto a card that would plug into something very fast, like a 16x PCIe bus, which in turn would be connected to a HyperTransport bus [but boy, wouldn't it be really cool if the DSP lay directly on the HyperTransport bus itself?].

    By the way, if anyone knows of a company that's making such a card, with stable drivers [or, God forbid, a motherboard with a socket for a 128-bit DSP on the HyperTransport bus], then please tell me about it, 'cause I'd be very interested in purchasing such a thing.

    We used iFolder 2 in a Novell cluster and it was a really nice product. Our laptop users loved it. None of the hassles of Windows offline folders (which seems to try to use a sledgehammer to nail in a tack) iFolder simply sits in the background and watches your iFolder for changes/new files and seamlessly syncs them with the iFolder on the server.

    If a file becomes dirty [i.e. if it's altered], then, traditionally, Windows copied THE ENTIRE FILE to the server.

    So if you were goofing around with a 1MB PDF, say, and you saved some changes, then Windows would push the entire 1MB across the wire.

    iFolder, on the other hand, pushed ONLY THE DIRTY SECTORS - if, for instance, your alterations were confined to a single 512 byte sector, then only that sector was pushed across the wire.

    So, in effect, Windows was like encrypted FTP, whereas iFolder was more like an encrypted file system over TCP.

    Traditionally the great drawback to iFolder was that its passwords and passkeys were not stored in NDS, so you had to remember a set of passwords and passkeys that were distinct from your NDS password, which put a real damper on things. Don't know whether they've cleaned that up in v3, but having to memorize a second set of credentials kinda obviated the whole purpose of turning to Novell in the first place.
