    I'll point out that it's not the absolute size of the donation that matters as much as the percentage.
    "Matters" for what? For pissing contests? Yes. For the charities themselves, I'm sure they don't care how much money Gates kept for himself. His $1B donation is still better than if you gave every red cent you have.

    Yeah, really. I can't believe the man can give billions (with a 'b') to charity and all people can say is "that's not enough".

  3. Re:Computer Engineering == Economics? on Survey Of Editing Tools For Building Ontologies · · Score: 2

    Computer science (and mathematics) has a long history of redefining common words. You have "assemble" and "compile", "class" and "type" and "method" and "code", "file" and "string", "stack" and "heap" and "hash", and so on. None of these has their original english meaning when used in computer science.

    If your concerns about war make you forget everything else, then welcome to 1984. "War is peace".

    Just because you sometimes use a command prompt doesn't mean you use DOS.

    The "if you're only using Office" argument is getting very tired. Especially when he said exactly what software he uses, and didn't mention Office. It's like a broken record every time the CPU speed debate starts up.

    There's a lot of software out there that doesn't max out a CPU these days, and it's not all office software. There's also lots of things that do max out a CPU.

    Everyone should just buy the hardware that suits them. It's not rocket science.

  7. What about a black hole? on Quark Matter Blamed for Paired 1993 Seismic Events · · Score: 2

    Does anyone know why this has to be strange quark matter, rather than a small black hole passing through the Earth? Is it because a black hole that small would explode from Hawking radiation?

    Good question. I guess it depends on whether antimatter has negative mass. AFAIK, all anyone knows right now is that it has opposite charges, and reacts violently with normal matter.

    While the comparison of this machine to the brain is questionable (being an apples-and-oranges situation), it's amazing that it takes this much effort to equal the computing power of a device that grows spontaneously out of organic goo.

    The Gobo libraries are a free, portable set of libraries. They're not as rich as the Java libraries---what is?---but I gather they are pretty good.

    I presume that by "cross polinisation" you mean "cross-pollenation". That is the transfer of pollen between two individuals of the same species. It can't make corn genes end up in soybeans.

    Are we talking about the same thing here? I'm saying client-side spam filters must not reject legitimate emails. I think that's a very uncontrovercial statement, and that it is also achievable (as demonstrated by the success of the Bayesian filters).

    If you are talking about the same thing, then I'm sorry, but I missed the point of your post.

    That's only half the picture. It also must let every non-spam email get through. It can't just discard important emails. Otherwise, I could provide you with a simple filter that blocks 100% of spam...

  22. Re:Here goes.... on The Law of Leaky Abstractions · · Score: 1
    I think you understand the code because you wrote the macro processor. I think this may be the next revolution in programming: that both the program and its translator are under the control of the developer. This subsumes paradigms like functional programming (where lambda expressions are nothing but translation steps) and aspect-oriented programming (where "aspects" can be expressed within the translator).

    One day I'm gonna do a PhD on this...

  23. Re:Merits of RISC on Boosting Battery Life For RISC Processors · · Score: 1

    Well, I'm not sure I agree with your conclusion (since there's still the CISC code-density issue), but it has been nice discussing it with you. :-)

  24. Re:Merits of RISC on Boosting Battery Life For RISC Processors · · Score: 1
    A compiler has more knowledge of the code than the CPU scheduler, thus, a compiler, given access to the inner RISC-like core, would be able to produce better code.
    The compiler doesn't really have more knowledge so much as different knowledge. The compiler's knowledge is static, unless it's a JIT, while the processor has dynamic knowledge. Most of the compiler's knowledge can be encoded into proper selection of the CISC instructions.
    For example, the scheduler cannot skip the calculation of irrelevant results forced into the code by a limiting CISC ISA.
    You mean like the div instruction computing both the quotient and the remainder? Ok, so that's one reason the ISA is not "completely" irrelevant, and is only "largely" irrelevant. :-)
    Also, it would (probably) be easier to write a good compiler for the RISC-like core, since it is bound to be more symetric (more gp regs, less restrictions in what op can be applied to what reg etc.).
    True, but that benefit would be lost if the core changes with each version of the chip. For instance, anyone who wrote a code generator for a P1 already had a pretty good code generator for the P2, P3, and P4, not to mention AMD and Cyrix processors, despite the fact that the innards are quite different. (Granted, the P1 codegen was a hassle. :-)

    Now, instead of targeting the RISC core, you could target a virtualized RISC ISA, while the chip does the same kind of translation internally into u-ops. In fact, an even better ISA for exposing a chip's internals to the compiler is VLIW (Very Large Instruction Word), and if you could write code in a virtualized VLIW ISA, that may be best of all.

    And with that, we have arrived at the IA-64 ISA. It uses something called EPIC (Explicitly Parallel Instruction Computing) which is a kind of virtualized VLIW/RISC ISA.

    Only if you ignore the money. We all have swap partitions because they are dirt cheap. A 2GB swap partition costs something like $5.00 on a modern hard disk. The 2GB ramdrive costs $3000.
