    Brazil is about how these movements fall apart and all we're left with the the crumbling infrastructure of a grand social scheme and petty regulations designed to protect that system that trap the ordinary fellow.

    1984 is about what the Western World feared communism would be. Brazil is about what communism, small-time fascism, and British capitalism all turned into.

    So yeah, it's just like 1984, but rewritten from the side of things where the worst didn't happen. That's not an insignificant contribution. If more tinfoil hat types would watch Brazil, we could all relax just a bit. It's not a nice world, but it's not that much worse than any world we've ever had.

    I think Dave Sims said, in one of his famous misogynists rant, that the key point in communism is that you do a lot of things to prepare society and then *boom*, human nature changes overnight, and you're free. Slashdot type know this as the ??? step. Brazil is about what happens if there is no ???.

  14. Other implications on Is Typing a Necessary Skill? · · Score: 4, Interesting
    If you learn to type via trial and error speedhacks, you have a tendency to AOL type, just as the parent said.

    That's a problem. It brings accents into the typing realm. British people AOLspeak very differently from Americans. Australians tend to just type relatively well, which is odd, but they do have their own short forms.

    The various slangs are based on whatever shorter way there is to spell the way the typist pronounces a word. Unlike the original online abbreviations such as LOL and ROFL, these new ones are not based on the typographic version of the word.

    Accents online is something we don't need. The beauty of someone typing properly is that anyone can read that text and understand it, short of something like "lift" vs. "elevator". I couldn't walk into Manchester's poorer districts and converse reliably. I now find the same is true of typing with Manchester residents.

    With Brit AOLSpeak, the first phrase you have to learn is "soz wot" which I think means "sorry, I don't follow." The second phrase is "i fink u spk 2 mingin posh u bastard" meaning "I am angry that you don't type the way I do." I'm not making that up, though I profess no great mastery of the form.

    Even within the single local group, the AOL speak tends to vary based on what kind of half-assed typing is being used. People who use three fingers on each hand choose different short forms than those who use only the indexes.

    Just as we need other web standards, we need a standard way of writing. It's not unprecedented... consider italic and cursive.

    Slashdot is such a public extension of the private geek fight. There are three principal outcomes to a geek fight:

Eventually the first geek realizes what ridiculous mistake the second believes the first to have made, and laughs mightily.

    b) The first geek does not know the truth about the point the second is bringing up, but would require a course in linear algebra and another in data structures to catch it, so he can't be convinced anyway.

    c) The two work together or are in school together, and so one has grasped a point earlier than the other and is teaching it.

    Hush Puppies are perfectly suited for hushing a puppy.... you kick the puppy.

    Wouldn't you say there's something linguistically missing if you say their Puppy nature is why they're so suited? They're also suited for hushing babies.

    Vector processors (big-V) are suited for dealing with vectors (little-v) because a Vector can contain the elements of a vector. Right. However, the elements of a Vector may not be a vector in any important sense, or worse, in a sense that twists the original meaning of the vector.

    The Vector you deal with may be composed of a dozen scalars you want to multiply by another scalar really fast. You store them in a Vector, you perform what is technically a vector operation on them, but they are not in any important sense a little-v vector.

    Say you're calculating the tax on a dozen shirts.... the vector containing the prices of all those shirts is not importantly a vector. If you let sV be a vector of shirt prices in the space of untaxed items, then you transform that into the vector space of taxed items... you're losing something important on the semantic front. The fact that you can view it this way is why it's called a vector processor, but it's naive. There isn't a thing in the world that isn't a vector when you're start talking that way, and the word loses its meaning.

    More telling is the case in which, for reasons of limited cache and to avoid stall, you have a set of spatial vectors Vn, and you define a Vector xComponentsVector to contain all the x components of spatial vectors in your scene. The operation you perform on xComponent completely obliviates the concept of a direct mapping between Vectors and your vectors.

    So all I'm pointing out is that there's a meaningful difference between a Vector and a vector, and that the reason Quartz and AltiVec are yummy to program for is that you can hand off vectors to the processor, yes... in the API. The Vectors that the processor calculates are very different indeed once the compiler has had its way, as with any data type.

    If you're genuinely hand-coding assembly language AltiVec algorithms and the Vector you throw at the processor is always significantly a mathematical vector on a symbolic level, I'll eat my hat while we discuss the many optimization opportunities you're passing up.

    "I truely fail to see how a desktop with 3D bloat will help over one with simple and fast 2D drawing."

    The point is that 3-D card compositing is actually much faster than 2-D compositing on today's cards. The hardware is no longer super-optimized for 2-D... nobody cares about 2-D hardware anymore. The way Windows moves windows is insanely slow.

    If I drag the window this browser is in on my 2.4 GHz machine with a Radeon 9800, I get tearing and it jumps around a bit. I have "display windows contents while dragging" on.

    2-D on Windows is a fifteen year old setup, more or less. It's time for a new model, with less programmer complication.

    If I run Quake III with vSync on, I get no tearing and I'm running at well past my monitors refresh rate... objects have apparent physical reality instead of this flitty flit windows nonsense.

    Today if you turn off 32-bit colour for 8-bit color, you don't make your machine faster. It's slower because Windows stores internally as RGB. Turn to 256 color graphics and you have to set the palette all the time through BIOS calls. Yuck.

    The same is true here... Windows is moving to a newer, faster graphics model. It's faster to have each application draw to its own framebuffer and let the 3-D card composite it. It's faster to not deal with actual blitting loops within applications that tie up the whole processor.

    No more clipping calculations for the various windows, no more trouble with more than one video application trying to use the god-damned overlay mixer, no more trouble with overlays not working on the second monitor of a dual-monitor setup....

    Don't think of it as 3-D bloat... that's inaccurate. Think of it as enabling the 3-D coprocessor that almost every computer will have at that time. You already know your P2-266 won't run Longhorn. 3-D doesn't make that more true.

    "Vector processors" do not accelerate the same kind of vectors that are involved in "vector graphics."
