  1. Re:register starvation on The Most Expensive One-Byte Mistake · · Score: 1

    Never mind, I commented too quickly. I was confused by needing an extra register but I'd forgotten you can't do a direct memory-to-memory copy.

  2. Re:register starvation on The Most Expensive One-Byte Mistake · · Score: 1

    OK, now think about how you would compile a loop; say, strcpy. With null-terminated strings, you can do this with one source register, one destination register, and one temp register to hold the value you pull out of memory.

    I'd use the temp register to hold the # of bytes remaining, and do the copy with XOR. :P

  3. Pretty much. on Followup: Anti-Global Warming Story Itself Flawed · · Score: 2

    the model used is 'unrealistic' and 'incorrect,' and the author has a track record of using bad models to make incorrect conclusions

    ...yeah, just about everybody on either side of the Global Warming debate says that about just about everybody they disagree with.

    (And very rarely does anyone say why a model is unrealistic or incorrect.)

    It's a pretty common mistake. Most people don't understand flash point. Its name doesn't really help either.

  8. Re:Easy enough on McCain Decries "Hobbits," Accused of Ringbearing · · Score: 2

    Flash point is not the problem. LEL/UEL and autoignition temperature are the problems.

    In an oxygen-rich environment, the LEL is lower, the UEL is higher, and the autoignition temperature is lower. The flash point does not change.

    Flash point is the temperature at which a flammable liquid (at STP) releases a flammable vapor (Wikipedia says "the lowest temperature at which [a volatile liquid] can vaporize to form an ignitable mixture in air").

    Now, for a short quiz to verify that you understand the concept of flash point: What is the flash point of propane?

  9. Re:This site works best with... on OK Go Goes HTML5 · · Score: 1

    No, it checks your user-agent and doesn't even give you the real page if you're not using Chrome. (It does, however, give you the option to go ahead and run it anyway. Maybe they added this recently.)

    Using a user-agent switcher gives you the real page (it still doesn't work on Firefox). Although there are Firefox add-ons that allow you to easily change your user-agent, you don't need to install an add-on if you'd prefer not to. From about:config, find (or create) the "general.useragent.override" string value and set it to:

    Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/A.B (KHTML, like Gecko) Chrome/X.Y.Z.W Safari/A.B.

    I also want to be able to click on an image and save-as easily. JS code just fights that.

    Actually - you're wrong there; this is drawn on an HTML5 canvas element. Right-clicking allows you to view it as a PNG or save it to your hard disk. It really is as easy as you described.

    You could even pretty easily code up something that would allow selection of a region of the canvas for saving, instead of the whole thing.

  11. You're all missing the point on Iran Forced To Replace Centrifuges To Stop Stuxnet · · Score: 3, Insightful

    It's an editorial, for crying out loud. Of course it's biased.

    The real news is that Iran is scrapping somewhere between 5,000 and 6,000 centrifuges and replacing them with "faster" and "improved" ones. They supposedly announced this in a press conference, so I presume this can be independently verified apart from DEBKA's claim?

    The rest of the article is conjecture, so feel free to come up with a better theory of why Iran is rebuilding their enrichment program from scratch.

    Actually TFA pointed out that the Android users were the only ones who could correctly answer that they "already own one", since there are 4G Android phones on the market (such as the HTC Evo 4G and the Samsung Infuse 4G). There is no such thing as a 4G iPhone or Blackberry; they don't exist yet.

  19. Re:Unfortunately.... on DOJ: We Can Force You To Decrypt That Laptop · · Score: 2

    Being required to enter the passphrase into a computer that the DoJ controls is exactly the same as being required to give your passphrase to the DoJ. There's no difference. Hell, what it boils down to is: Don't give me your passphrase; just enter it into this computer which I control. How many Slashdotters would balk at that? Hopefully most of them.

    There are any number of ways that the DoJ could get your passphrase if they wanted it, and were permitted to demand that you enter it onto their computer - a keyboard dongle, a software keylogger, a hidden camera showing the position of your fingers - even just a hidden microphone could be used as there have even been programs written that can do acoustical analysis to determine which keys were typed. They might even be able to do a plaintext attack on the encrypted data using a decrypted file. Not that any of that would matter, anyway - they don't need your password any more once the data is decrypted.

    If you're required to type your password, you've just given it to them, for all intents and purposes.

    Of course not. If you did it all by yourself you didn't pay anyone.

    However if you bought a book on how to do it, paper, and a pen... you apparently can sue each of those companies for "assisting" you.

    Actually that's already been done and tried and failed. From TFA:

    But in 1978 the Missouri Supreme Court effectively narrowed that language when it reviewed a case in which Missouri bar authorities sought to punish the sellers of a divorce kit that consisted of nothing but blank legal forms and instruction booklets for filling them out. The court ruled that merely marketing such materials did not amount to practicing law absent "personal advice as to legal remedies or the consequences of flowing therefrom."

The court ruled that merely marketing such materials did not amount to practicing law absent "personal advice as to legal remedies or the consequences of flowing therefrom."

    A booklet instructing you how to fill out legal forms is not legal advice, according to that ruling. Neither then is software that instructs you on how to fill in the blanks on a computerized legal form.
