  1. Whittle patented his design quite early... on Second Hypersonic X43 Scramjet Ready for Testing · · Score: 2, Informative

    And as for the Nazis developing the first jet engine, Sir Frank Whittle might have an argument with that. (Although the Germans may have had a jet -powered aircraft in the air first.)
    IIRC, according to "Inventions that changed the world", Whittle patented his jet engine quite early on (I think before he'd built a working version) which meant that it became public knowledge.
    It's quite possible that the Nazis saw this patent and, of course, probably didn't feel the need to pay any licencing fees for their development :)

  2. Re:Imperial is actually better. on Another English/Metric "Spacecraft" Problem · · Score: 1

    Why? Because it's not base ten.

    Using imperial measurements, you can accurately cut a third of a yard, half a yard etc. And I don't mean none of this 33.333333 recurring crap either. You can cut a perfect third.

    I was in england last semester and nearly everything was still refered to as stones. Nobody knew either kilograms or pounds, I always had to convert everything to stones for them.

    You must have been in a strange part of the UK! The only time I've seen stones used is when measuring body weight.

    Why do you call them 'English' units, when everyone else knows them as Imperial units? :-) We stopped using most of them some time ago.

    Especially since, IIRC, "Imperial" does not refer to the British Empire but to the Roman one.

  7. Re:Corrections to your Kyro 2 "info" on The Return of S3 · · Score: 1

    Remember the Kyro II? The chip used a unique tile-based rendering system ....
    That bit was correct..

    Flash forward a couple of years, and while NVidia and ATI are still willing to release updated drivers for their cards of that era, the Kyro lingers unsupported,
    This is incorrect. IIRC, there was a new driver release about 1~2 months ago. Go look on the PowerVR web site.

    even though NEC (the chip designer) and
    Kyro was designed by PowerVR and ST. NEC were involved with the previous generations (including the Dreamcast version).

    My friend wanted to play Halo, and even though the card should've been able to support the game (albeit at a lower resolution/framerate), he can't because his card is basically ignored and unsupported by the game manufacturers and the source comapnies for the card itself.
    Ignored by whom? Certainly not the driver writers. There are, however, a number of games which were testing for the existence of HW T&L and refusing to run even when running T&L on a modern CPU resulted in perfectly acceptable performance. New drivers have been released which coerce such games into running. Obviously, if a game insists on, say, DX8/DX9-only features then there is little chance of getting Kyro to run!

    Oh, BTW apparently Halo is running on Kyro.

  8. Re:High Performance for General Purpose? on BrookGPU: General Purpose Programming on GPUs · · Score: 1

    I suspect that this high performance is only attainable for the field the GPU is specialized for, i.e. graphics-related things. Or isn't it?

    It is for "more specialised" tasks but it certainly isn't restricted to graphics. Computation such as FFTs and Fluid Flow is also possible.

    If, like me, you couldn't get through the home page, this sort of thing (including, IIRC, Brook) was discussed at Siggraph and also
    this year's Graphics Hardware conference.
    Scroll down to the "Panel: GPUs as Stream Processors" and "Session 4: Simulation and Computation" sections for slides.

  12. Re:Not really a cruise missile on DIY Cruise Missile Grounded · · Score: 1

    Um, I believe the V1 was a ballistic missile - not a cruise missile. They're quite a bit different from each other. A ballistic missile just follows a trajectory so it falls more or less near its target,...

    I believe you're thinking of the V2 - the rocket-based "Vengence weapon". The V1 a.k.a. "buzz-bomb" or "doodle-bug", was an unmanned pulse-jet aircraft and thus was not following a trajectory per se. It would have had to have some minimal in-flight navigational ability even if that was just to fly in a straight line at the right altitude until it ran out of fuel.

    The British, however, had control of much of the German spy network (ref the book "Station-X") and so kept feeding back info that the V1's were over-running London. The Germans thus put less fuel into them and so they subsequently fell short of their target.

    I suppose the Germans could have tried used the navigational beam system they'd originally used for bombing raids but, then, those had been discovered and jammed by the Brits.

  13. Re:Is 576bit big? on RSA-576 Factored · · Score: 1

    Wow, I havn't really read in to it, but is that very big? I mean, they were talking about not too long ago that 128bit encryption is "almost impossiable" to break. If this is 576bit encryption, and they've broken it, doesn't this mean that 1024bit is looking slightly weak? Whats the 'difficulty' of breaking this key on a relative scale?

    You're confusing symetric key ciphers (eg AES (Rijndael), DES, Blowfish etc) with the public/private key ciphers (RSA, Diffie-Hellman). The former can use any "random" pattern of bits as the key, whereas the latter need a much larger key size because they rely on certain numeric properties of the key or algorithm.

  15. The abstract from the earliest cited patent: on Microsoft to Charge for FAT File System · · Score: 4, Informative
    Just to follow up, the first patent that MS list as protecting FAT (US5,579,517) has this as the abstract:

    An operating system provides a common name space for both long filenames and short filenames. In this common namespace, a long filename and a short filename are provided for each file. Each file has a short filename directory entry and may have at least one long filename directory entry associated with it. The number of long filename directory entries that are associated with a file depends on the number of characters in the long filename of the file. The long filename directory entries are configured to minimize compatibility problems with existing installed program bases.


    Do these devices really need compatibility with "dead" operating systems?

    The second patent seems to another concerning filename formats. I haven't bothered to look at the other 2.
  16. Something must have been updated... on Microsoft to Charge for FAT File System · · Score: 4, Interesting

    This one isn't really submarine --- They created FAT in 1976, according to the microsoft.com page ... but the earliest patent was filed in 1995.

    That can't possibly be right. In the US (but nowhere else) you have a 1 year's grace period from the time of publishing an invention such that you are still allowed to patent it. Even with the USPTO's track record (!!) I honestly can't see them granting a patent based just on 1976 technology. MS must have included new ideas... or something like that.

    So the "A1" that runs northwards from London is a complete figment of my imagination?! I wish the same could be said for the traffic jams on it!

    Back on topic-ish, there's a section of the M1 in the outskirts of London that runs parallel to a major line. The cars and trains seem to travel at about the same speed in that section so I suppose there's a chance of some (very dangerous) bandwidth theft.

  20. Re:Well, sort of. on Video Card History · · Score: 1, Redundant

    The card took up its own slot, and used a pass-through video cable to connect the monitor: When a Voodoo-compliant video signal was detected, it hijacked the output to the monitor and took over.
    Nice design, for the time. The best thing was, it was CHEAP for the time (considering the performance). I think I paid $199.


    I personally think (but I am biased) that the PowerVR PCX1/2 solution was nicer. It also piggy-backed off the 2D card but, instead of using cables, it squirted pixels (in packets) across the PCI bus into the 2D card's memory and so could even do 3D in a window. The scheme wouldn't work well today with ultra-high resolutions but it was fine for 1024x768 @30+ Hz.

  21. Re:PowerVR. on New Graphics Company, With Working Cards · · Score: 1


    There are two problems with the old PowerVR cards:
    a) no hardware T&L
    b) no cube map support

    The implications of the first are pretty obvious. As long as a game can run on a TNT it should be ok on the PowerVR; but once it expects T&L hardware then you might as well have Intel's integrated graphics hardware...


    Actually the first is really not a big problem if you have a reasonable CPU. AFAIU there is a customisable option in the driver that tells these annoying applications that the system "does" have HW T&L and then runs it on the CPU. It often makes little difference to performance because you are probably fillrate limited anyway.

    Cube maps, OTOH, are more of a nuisance to work around. It's especially annoying if they're only being used normalise a few interpolated vectors for lighting. You could probably live with a few dimmer pixels.

    No! The drivers are still updated! The most recent releases for Windows AND LINUX are only about 1 week old. You can find them at the PowerVR Dev site. For some reason these are not yet on the main PowerVR downloads page but I suspect that it won't be too long before they appear.
