  1. Re:Pi on Fun with Prime Numbers · · Score: 1

    After seeing Plouffe's inverter, calculating digits of Pi doesn't seem as interesting. One can easily calculate the nth (hex) digit of Pi in constant time, without any FP...

    Too true! Twice as little is also accepted i believe. :)

  3. Re:So... what are stores going to do? on Retailers Deploy Databases Against Customers · · Score: 1

    Oh god..THOSE people. You think you have it hard working in the service? Wait until you work in a hotel. You get to constantly hear them whine about everything for however long they decide to stay. Word to the wise: people who try and bargain more than 1 minute aren't worth the trouble, even if 1/3 of your rooms are still empty.

  4. Re:Well on Retailers Deploy Databases Against Customers · · Score: 2, Interesting

    I'm reminded of H&M, where they tell customers over the PA that they can just return items instead of waiting to try out the clothes. I guess the practice of buying and returning clothes isn't as bad as it sounds. Plus, there are situations where you simply can't know if it'll fit, be it because you're buying for someone else, (the following mostly applies to women, i guess ;) you don't have the support you want to try it with, or (you think...) you're bloated.

  5. Re:Interesting food for thought on Painting Political Graffiti With Light · · Score: 1

    A laser would be more like vector graphics, so it's mostly line art only. The persistence of vision would likely be the botteneck, but i guess you could use multiple mirrors. I don't think it'd be better here.

    "For people who learn a 2nd language pass the "cut-off" point, when they get old, (or are weak from sickness) they will default back to their native language."

    What about those of us with no first language? :) Seriously, my French is tainted with English (unidiomatic phrasing and use of certain words, outright invention of words, etc.), and vice versa. Yes, this does sort of suck, but bilingualism still > unilingualism.

    It actually was not libel, since it was true. In most of the cases I can remember, the complaints were either about name-calling (mm yeah. no comment), or things the plaintiff said, verbatim. Remember, it doesn't matter if it hurts - it's not libel if it's true!

  8. Re:Dictionary=Bad on Shorthand-Aided Rapid Keyboarding · · Score: 1

    You can always tap. The ATOMIK layout was created to be used a virtual/tap keyboard. QWERTY was better for me as a tap keyboard because i was much more used to it, but, in conjnunction with SHARK, i prefer ATOMIK. I think I'll learn ATOMIK well enough after a couple weeks.

  9. Re:I would have to try it to know if I would like on Shorthand-Aided Rapid Keyboarding · · Score: 1

    Try qwerty or ATOMIK touch keyboard hacks for Palms. SHARK hasn't been ported to Palm (or PPC), unless they now have real JVMs - maybe the Zauruses do? It doesn't seem like it would be extremely hard to do, except for graphical feedback, but it _is_ a completely different beast from the usual touch keyboard. In the meantime, there's a Libre hack (can't find it, sorry), and a couple shareware ones, that allow you to use qwerty, ATOMIK or arbitrary layouts if you prefer azerty, etc - the last time i checked the author was still working on OS 5 support. I find that qwerty was faster than graffiti, even though i have to tap each letter, and, on non pure english tasks, better than ATOMIK. I can easily see how i should type words on qwerty without any reference, so obviously the layout worked well for me. A con is that you have to look at the graffiti area when inputting data, but i find that i have to when using graffiti too, anyway.

    Now, I just keep it in ink on my Tablet, but if the demo works well, I shall be a happy man. (No, HWR does not deal very well with programming or shell commands :)

  10. Re:Switching time?? on Optical Control of Light on a Silicon Chip · · Score: 3, Informative

    From TFA:

    To turn the switch "off," a second beam of light with a wavelength in the same spectral range is sent through the system. This wavelength is absorbed by the silicon through a process known as two-photon absorption creating many free electrons and "holes" (positively charged regions) in the material. This changes the refractive index of the silicon and consequently shifts the resonant frequency of the ring enough that it will no longer resonate with the 1555.5 nanometer signal. The process can theoretically take place in a few tens of picoseconds.

    Very interesting stuff... It's kind of like EIT, but much more sensitive.

  18. Why this isn't the same as T9. on Statistics For Data Entry: The Brave New Step · · Score: 4, Informative

    Having used both dasher and T9, it seems to me that t9 only takes into account the keystrokes entered for each word. It then correlates them to a dictionary. Dasher, on the other hand, is based on markov chains (yes, like those word/text generators), and thus takes into account the last [n] characters. That makes it much more accurate, and, interestingly enough, should make it particularly well-suited to editing programs in most mainstream languages, since they have a lot of noise words and frequently used sequences.

  22. Re:GCJ slower than a native JVM? on Java VM & .NET Performance Comparisons · · Score: 1

    If you actually take a look at what optimizations are used in JVMs' you'll notice they are typically not very sophisticated. JVMs simply can't afford to use optimization techniques which take too much time.

    Which is exactly my point: GCJ CAN afford those more expensive static optimisation techniques, like full stack caching. This should help a lot, even though it doesn't have access to runtime data.

    See all those straight lines? That's pure redundance. They add no meaning to the expression, only more typing effort.

    Algol-like being basically the hardest kind of language to parse, and not exactly orthogonal, that's like saying it's the least bad of the worst. Small functional languages (just allocate everything on the heap - and note i didn't say Lisp. No parens if you truly despise sexp :) or concatenative languages are probably easier to parse and to compile.

  25. Re:Can be subverted on Secure, Portable, Virtual Privacy Machine · · Score: 2, Interesting

    IIRC, it doesn't apply here. The research was made on the JVM, showing that its security was vulnerable to gamma rays, etc, which isn't a big surprise. I'd expect the same for any other program. However, they also managed to craft their program in such a way to basically escalate the program's (class?) privilege level reliably. QEMU has different goals than JVM's security, and it being vulnerable to mutated data isn't more critical for it than any other program. You might be referring to another study. though; that's all IIRC.
