    Great. Greg advocates PNG, documents it, generally makes the world a richer place, and you have to nitpick terminology. Maybe you have a (trivial) point, but your attitude is what I object to.

    Geeks routinely abuse English, and a consensus develops that makes school teachers mad, but you'll find that the geek terms acquire a certain standardisation and add meaning to English it didn't have before.

    For example, 3D graphics uses terms like "transparency" meaning [for 8 bit values] that (0 is opaque, 255 is clear), then introduces "opacity" to mean (0 is clear, 255 is opaque), THEN confuses us all by using translucency to mean (something between 0 and 255) - which goes against the dictionary - look it up.

    English is a dynamic evolving thing, as are science and technology. Think about that.

    I see a few mentions of eye surgery. Please don't let /. or newsgroups be your main source of advice in stuff to do with your eyes, consult a number of patients and surgeons, doctors too.

    That aside, FWIW, I have had cataract surgery in both eyes. I have fixed focus but the clarity is little short of a miracle. I know the down side btw.

    My point is that enhancing eyesight with "cool" technology shouldn't be done as some sort of geek fashion statement, because messing with the highest bandwidth input to your brain is -risky-. Please, look after your eyes.

    My post is anecdotal because I don't know how it got into my mind or where it came from and i can't give a reference, I'd appreciate it if anyone knows more.

    It seems that operations to cure a squint in children used to be done several months or years after birth, until someone did an experiment on some kittens (shudder). Point is, they proved that it really was essential to fix the squint almost straight after birth and many children benefit.

    I'm agreeing with you btw, just thought I'd lob this story in as an example of where the border between good and evil lies - for me. If I've unwittingly perpetuated a myth, I'm sorry.

  8. Re:But its only 32-bit! on Microsoft Releases First X-Box Screens · · Score: 1

    But the P3 is 128-bit'ish'? Its x86! Has the x86 line secretly gone from 32-bit to 128-bit? So where can I find a 128-bit operating system to take advantage of this? Or a project that's trying? Or are we talking here about a few instructions that store their parameters in enough registers to add up to 128-bit?

    Close. The P3 has some 128 bit instructions bolted on. To be fair it has 64 bit data paths so it has to do 128 bit instructions over two cycles, which means it has fun if there's an interrupt in-between. I don't want to think what a Transmeta processor is bit-wise.

    For most processors, the instruction size, the data path widths, the addressing range all require different numbers of bits, so using one figure of merit (X is a 43 bit processor) is difficult. As is a 128 bit OS - most folks have no need of 2^128 bit addressing, but being able to use the 128 bit SSE (Intel) or 3D Now! instructions is a real world benefit to lots of us. So attaching "bit-size" labels to complex things like a CPU or an OS is hair-splitting and doesn't inform, which was my point

    As regards the US cars, supporting lack of facts (did you look at the processor data sheets) with analogies isn't cricket either.

  13. Re:Bullshit! on Create Your Own Psuedo-RDRAM · · Score: 1

    I just took another look at the article. The copper sheet is earthed via a wire and a crocodile clip. If anyone here did an electronics course, remember how you never got a square picture of a square wave on the oscilloscope screen until you used the right earthing attachment and calibrated the probe tip? Anything that the copper shield picks up flows back to the case via the inductance of the cable and the mechanical (not soldered) crocodile clip connection, which will ring like crazy at high frequencies.

    At least try soldering the copper to all of the SIMM ground pins to get a good earth. Then I would ask if all that extra capacitance isn't loading down the signal traces and slowing down your system.

    The more I think about this, it is bull. I do know for sure that getting earthing and shielding to work is as much an art as a science, but the test of science is whether or not this makes a measurable improvement.

  16. Gilding the lily on US PlayStation 2 To Have A Modem & Hard Drive? · · Score: 1

    I've got a PS2 sitting in the living room right now and it is incredibly disappointing. The visuals are underwhelming. I'm looking at Ridge Racer V, Streetfighter 3, Dead or Alive 2, Eternal Ring, and none of it looks as good as SoulCalibur or Shenmue. OK, the Sega needs a VGA adapter to shine and the PS2 is going through an NTSC/PAL converter, but what I'm seeing is fundamentally broken.

    There are 4 Mbytes of DRAM. Allocate 2 frame buffers and a Z buffer and there's not much room for textures. It looks like they've shrunk the buffers to the bare minimum to make space for textures, there are huge crawling jaggies, sparkly junk on textures, big blocks of smooth colour (no texture), bleah! BTW, the DVD software went away at random as advertised on Slashdot, never to be seen again, so no opinions about the video.

    Now, we all know game developers need time to get the best out of a machine, but Sega play by the same rules and got off the blocks in good shape, whereas doing PS2 must be like running with a ball and chain attached.

    Last I heard a PS2 cost $560 to build, a modem and a hard drive will take that up to what, $700? If it sells for $250 that's a lot of title revenue needed to subsidise it. Maybe they can make the modem ($40?) work as a business, because that way lies online games, but what is the hard disk for? They could make a TiVo with it for sure, but bundling doesn't make sense, they should sell it (or the services it enables) as an option instead of carrying the cost for all those kids who use it for games.

    I guess what I'm trying to say is that I don't believe articles about PS2 taking over the world anymore.

Offering better frames per second won't work, because either the 2001 game was jerky or it was playable, if jerky it bombs in the market, if playable 2003 model has only one advantage, marketing specs, but since gamers judge the game not the platform only suits care. Game development takes time and money, there's a certain security in developing for a non-moving target.

    I'm glad I got here early. I recall (can't be bothered to trawl the archives) the debate about nVIDIA and X and Linux getting rather overheated last time. My work was one of the casualties of an idiot negotiation tactic (I'm being vague in case someone tries it again - sigh).

    I've been in through the front door of nVIDIA, worked with a couple of their engineers and met a handful of people at various levels. I'm not name dropping or trying to be cool, just maybe trying to establish a modicum of credibility. Most of the folks I met I liked, although the culture gave me a few problems 'cos I'm from Europe.

    My point is this: nVIDIA (that's how it's written on my TNT card, wish they'd make their mind up on the capitalisation) is not a monolithic organisation. For all we know 49.5% of them want to do things the Slashdot way, and it might take a just little more polite persuasion to open things up, charm their management, whatever.

How will it support higher res with 4 Mbyte of embedded DRAM, it must have a hard enough time paging the textures in and out (yes, go figure) - I hope they compressed their textures like the Dreamcast does, but they're worryingly quiet about that.

When we've got full scene antialiasing and stable anistropic filtered textures, then there's the whole physics thing to get right, and better lighting, accurate shadows and so on. Even if by say the next generation we are able in theory to paint anything we like, and the renderer will do what we tell it to do, I think we won't fully understand how to instruct it in real time even then.

    It is really shitty that PSX2 is not going to be compatible with all PSX-1 games as initially thought. Stupid move on Sony's part. These companies invariably fail to see that good backwards compatibility is key to advancement & not a hinderance as simple economic theory might suggest.

    We can't condemn Sony for giving game developers low level PSX2 programming details nor the developers for making use of them to get better performance. That's simple economics, because no-one will give an inch to the competition to safeguard the future. Would anyone slip release 3 months or risk a bad review by avoiding dirty tricks? If everyone stuck to the graphics APIs then engineering back compatibility would be easy, but no-one does because coding to the metal always happens. A thought. if the PSX2 hardware has to emulate every quirk of the PSX, imagine what PSX3 (three) back compatibility requires?
