  1. Re:Um, Thanks But No on Google Releases Source To Chromium OS · · Score: 1

    There's a whole difference between how you store your data (punch card, magnetic type or harddisk), or whom you give your data. Maybe you don't care if your data is analyzed to allow for more personalized marketing (you think they wouldn't do that? Think again!). I do care.

    Oh, and do you think you'll be able to run adblock on ChromeOS? Surely not (or if yes, then only a version which doesn't block Google/Doubleclick ads).

    If you have infinite trust in Google, you probably deserve no better. I use Google for searches (Cookie blocked, of course) and for Google maps, and I'm watching videos on YouTube. But that's it. I don't have nor want a gmail account. I don't use Google apps. I block Google Analytics (if you want usage statistics, analyze your own server's log files, those contain all the relevant information; I don't want to leave a web browsing profile at Google).

  4. Re:GOTO ... on Building a 32-Bit, One-Instruction Computer · · Score: 1

    If you make a one-instruction CPU, then the obvious choice of instruction would be DWIM. Note that with that instruction you could restrict yourself to one-instruction codes without losing generality, which should greatly simplify the processor design (for example, you need no instruction queue; indeed, you can spare the whole instruction reading circuit, because you know what instruction you'd read anyway).

  5. Re:Cheating? on Building a 32-Bit, One-Instruction Computer · · Score: 5, Interesting

    I'd also consider it cheating. I can also invent a one-instruction computer, where the one instruction is a move immediate instruction. The move instruction moves a byte-sized value into a "command register" which does different things depending on the value of the byte you load into it and the current state of the machine. Indeed, since there's just one instruction, and it always has a single one-byte operand, I just don't encode the instruction itself, I just put all the operands into memory, one after another. And I define the state machine so that the actions are exactly the same as the actions of an x86 interpreting those bytes as separate instructions. Therefore I can avoid doing an implementation myself; I can just use a stock x86 processor as proof of concept.

    Well, that's what my computer already does: When it's on, it's hungry (it continuously needs to get new energy). When it's not hungry, it's off, and then it will completely ignore me, with the exception of the power switch, which will immediately make it hungry again. If it doesn't get food, i.e. electric power, it will even ignore the power switch.

    If there will ever an electronic brain, those were indeed all steps toward it. And if there will never be an electronic brain, those may still have been steps toward it. Just that you make steps toward something doesn't mean you reach it. It doesn't even imply that you can reach it. I easily can make a step towards the sun when it is on the horizon. I'll never reach it that way, though.

  18. Re:One word... on IBM Takes a (Feline) Step Toward Thinking Machines · · Score: 1

    With one 8-bit byte per character, it needs 40 bits (5 characters * 8 bits). However, since all five characters are in the ASCII character set, which is just 7 bit, 35 bits should suffice. Now, of course there are also encodings possible where exactly 32 bits are needed; but then, I counter with an encoding where "M" is 00, "e" is 01, "o" is 100, "w" is 101, "!" is 110, and all other characters have encodings starting with 111. That makes just 13 bits for "Meow!"
    Unless you restrict your encoding to only have those 5 characters, you cannot get any shorter, at least when encoding all characters separately. But then, who tells me that this is necessary? Therefore I now introduce the "cat encoding": The bit 0 stands for the string "Meow!" which anything else is encoded with bit sequences starting with 1.

    So I finally conclude: You need just one bit for "Meow!"

    Oops, I just notice that I replaced 114 by 116, so subtract 256 from the factor.
    But then, by looking again at the summary, the 114 is also wrong; it was 144 TBytes, so add 3840.

    That is, it has exactly 18432 times as much memory as your computer.

    What in the world is wrong with me? I must be getting senile. I've done this math like five times now and keep getting different answers. I think I need to re-learn how to type numbers into a calculator.

    Or you have to learn to do math without a calculator.

    1 TByte = 2^40 Bytes.
    8 GByte = 2^33 Bytes

    So 116 TByte/8GByte are 116*2^7 Bytes. Since 2^7 is 128, it's a factor of 116*128.
    100*128 = 12800
    16*128 = 2^(4+7) = 2048
    So 116*128 = 14848
