  1. Re:Lol on The Most Dangerous Programming Mistakes · · Score: 1

    Are you sure? I haven't read the article, but I'd guess they mean different things:

    • Inclusion of functionality from untrusted control sphere: Relying on code outside of your control (like many web pages use googleapis.com, but possibly with code from more shady places).
    • missing authentication for critical function: The data is valid and interpreted as intended, but it isn't checked that the user is actually allowed to do that.
    • input validation error: This input isn't valid, but the page doesn't detect it.
  2. Actual most dangerous programming error on The Most Dangerous Programming Mistakes · · Score: 1

    We may hit this one soon. I've found the following code in universe.h:

    struct particle particles[37];
     
    #define ELECTRON 0
    #define ELECTRON_NEUTRINO 1
    #define MYON 2

    I skip a few lines here, to come to the relevant one.

    #define HIGGS 37

    It's obvious what will happen if we ever produce a Higgs particle at LHC.

    I've already sent a bug report to god, but I haven't yet gotten an answer.

  3. Re:Post-quake Japan? on How Japan's Data Centers Survived the Earthquake · · Score: 1

    Maybe the people operating the data centers should also have been responsible for the nuclear power plants.

    Well, except Sony. Because then we would not speak about a nuclear power plant failure due to a tsunami, but a nuclear power plant failure due to insufficient security ...

  4. Re:Is that base ten or base e? on Algorithm Solves Rubik's Cubes of Any Size · · Score: 1

    When talking about computational complexity, fixing a base of the logarithm makes no sense at all. Changing base just means a constant factor, and constant factors are ignored for complexity considerations.

  5. Re:From TFA... on Algorithm Solves Rubik's Cubes of Any Size · · Score: 1

    Well, for a sufficiently general definition of "move", each cube is solvable in a single move. :-)

  6. Re:Pull off the stickers! on Algorithm Solves Rubik's Cubes of Any Size · · Score: 1

    I see, the challenge is in remembering the position of the colors on the cube, to avoid someone detecting your cheating after the fact because two colors which were on opposite sides of the cube before now aren't.

  7. Re:The end result on The Science of Human-Robot Love · · Score: 1

    That's a great link and all, but slashdot is so broke I can't left, right nor middle-click it to do anything effective. Anyone else having this problem?

    For me, only left and middle click is broken.

  8. Re:Money isn't cool? on Cool-Factor Predicted To Spur Energy Conservation · · Score: 2

    I can't think of any time when saving money was considered 'cool'. Smart, sure, but then again 'smart' was rarely 'cool', either. Most societies idolize overblown displays of wealth and physical ability, not thrift and intelligence.

    Well, maybe then we must make it that having energy conserving technology shows wealth. Make energy saving products expensive and look expensive. Then, gradually introduce less expensive models (but not too fast). Slowly the "if you have it, you must be rich" will turn into "if you don't have it, you must be poor". Which still is a great incentive to get it. And by the time that everyone (actually, everyone who could afford the non-energy saving equivalent) can afford it, it will be the normal thing, and nobody will even think about buying something else; the market for the environmentally unfriendly alternative will just have vanished.

  9. Re:Money isn't cool? on Cool-Factor Predicted To Spur Energy Conservation · · Score: 2

    While we make fun of engineers, people in India and China consider it a highly respected profession, the way we do with lawyers.

    "Highly respected profession" and "lawyers" doesn't fit together very well, I think. Or did I just miss some irony?

  10. Re:Well thought out design on Google's New Design · · Score: 1

    They already have feature creep and bloat.

    Google Instant, for example. Would be easy to circumvent by blocking scripts, except that this also blocks all the useful scripts on maps&co., too. The result is that I'm constantly enabling/disabling scripts for Google (even worse than Instant is that the key up/down for scrolling the page doesn't work any more, because Google thought it was a good idea to use them to duplicate the browser functionality of selecting the previous/next link).

    If they don't fix that, I may ultimately decide not to search with Google any more.

    Isn't that what people used to unlock restricted multipliers on microprocessors? Or did those pens us a different conductive metal?

    In Soviet Russia, we used a pencil.

    I see, you already did Graphene transistors.

    Yeah, but my power bill doesn't have a line item for "energy provided for conversion into another form".

    Oh, and before I forget it. You don't pay them for consumption, you pay them for delivery. You still have to pay them immediately if you put the energy into a battery for later use.

    All humans don't have the exact same genes. Caucasians generally have a lesser bone mass to Africans. Facial features are radically different between different races, as do skin pigmentation. How can the mind be isolated from all of this?

    Well, it's just that "Caucasians" cannot accept that they not only have weaker bones and a weaker sun protection in their skin, but also a weaker mind. :-)

    Well, this isn't about paying for playing. This is about paying for in-game items with real money. That is, the money you put in affects your in-game success. That makes the game unfair.

  22. Re:Art project, not a working 10k clock on Long Now Clock Advances With Bezos Cash · · Score: 1

    Actually, for any creature which developed on earth and is able to percept light, we can say for sure that they will be able to perceive that sort of light which reaches earth in non-negligible amount, which is mostly the visible range and neighbouring frequency ranges (UV, IR). OK, radio frequencies also reach the earth, but apart from being far less in natural intensity, due to their longer wavelength and lesser interaction with most materials they are far less useful for the main pupose eyes are developed: Perceiving the things around you.

    BTW, would your 294Uuo signature radiation actually reach the ground, or would is share the fate of most electromagnetic radiation, namely be absorbed by the atmosphere?

    The unlikely-to-be-natural would be in the signal the satellite sends. That signal would have to be made obviously artificial, like a sort of Morse code. Note that e.g. the DCF77 time code is also a sort of Morse code, with signal durations of 0.1 and 0.2 seconds (where "signal" means a decrease of intensity). Now to be human-perceptible, the duration of the peaks (at least the long ones) should surely be longer (and probably the signal would be appearance of light, rather than pauses, because short flashes are more easily spotted than short pauses of light).

I'll definitively not allow it to use unnecessary CPU power. (And before you ask: Yes, there's a computing cluster. But normally, that cluster is full and my desktop computer is free.)

    Considering each clock is using orders of nanowatts when you have almost a milliwatt to play around with, a wireless time on demand circuit could be designed to be powered by the excess power generated by your U235. How about a transmitter that would occasionally beacon with the electromagnetic signature of something uncommon, such as 294Uuo which has a half life of under a millisecond. Now a flash of that would stand out, eh?

    To someone who has no idea what 294Uuo is? Or what even an electromagnetic signature is? Not at all.
