    Good thing they banned lighters, then! ;-) Just kidding, I agree. But, if they took fires seriously, I'd expect a lighter ban. But, the tobacco industry has bought a lot of pull among politicians.

  3. Jiffy pop on How To Tell If It's Really Titanium · · Score: 1

    We were ready to pop some Jiffy Pop at a campfire, when then noticed it had a warning "do not use in campfires." We tried it anyway... the aluminum foil pan burned in to nothing before the popcorn popped, so we were left with just the steel handle.

    Yes... I fly with them occasionally, and they are very aware of this. We had a call for something serious in a neighborhood next to an outdoor festival -- they purposefully kept away from the festival so that it wouldn't disturb it and wouldn't look like they were monitoring it. I know all the cops who fly in our city (it's just a handful), and they're all very professional. Hope the same's true in your city -- flying the helicopter is a privilege; they don't just stick any bozo in it.

  8. ... don't buy broken stuff on Western Digital Service Restricts Use of Network Drives · · Score: 1

    Hacking is fun in itself, but when something is painfully broken as this, it's more of a chore. I'd much prefer to buy a drive that shared all files to begin with.

    I'm the guy behind most of the disposable digital camera hacks (to allow people to get their pictures), and there are some parallels with this product. It would have to be heavily discounted or offer some other unique novelty before I'd touch it.

  9. Re:Consume 1.5 Volts? on Samsung to Produce Faster Graphics Memory · · Score: 1

    If there's capacitance in the circuit (and there always is), then a lower voltage means less current. Less current means less power.

    I = C * dV/dT .. so, if you manage to get something to work at half the voltage, you can double the frequency (speed) and still consume the same power.

  11. homemade RNG on Loophole in Windows Random Number Generator · · Score: 1

    I was using a vendor's demo code for some low-level fiberchannel control. Their application would fill a buffer with random data, loop it back over the interface, and compare it. It seemed to work for large transfer, but it would report that the first 3 bytes were corrupted. Digging deeper in to the code, I found they were reusing some buffers... not great, but if their random numbers were good, there would be no chance that the previous buffer equals the new buffer... then I checked out their random number generator: 92, 17, 204, 3, 3, 3, 3, 3, 3, 3, 3, 3 ...

    I'm a big fan of keynote.. it just blows the doors off of powerpoint. My favorite feature is the ability to cut the subject out of a picture so that you don't have a distracting background (example).

  14. Resolution and Evidence on DHS To Share Spy Satellite Data Over the US · · Score: 1

    When you start using data from spy satellites, it's unlikely that a defendant will be able to see the evidence against them. The capabilities and resolution of spy satellite photos is classified, so all most people will see is down-graded view. Even military commanders in the field get an interpretation -- they ask about particular features of a potential target, and then a photo analyst draws them a picture describing the photo. That way, the picture (and the satellite's capability) can't fall in to enemy hands.

    This is good and bad -- good as in that police will need additional evidence to use this in individual prosecutions, and bad in that the secrecy surrounding spy photos could be used to manipulate the legal system ("trust us, Judge").

  15. Re:DMCA on First iPhone 3rd Party GUI App Compiles · · Score: 3, Interesting

    The DMCA exemption is exceedingly narrow -- it only allows you to connect to a network, not run your own apps. It's so limited that a PC-based unlocking program wouldn't be allowed to bypass the DMCA to install the (temporarily legal) firmware, because the exemption applies only to firmware that runs on the phone and not regular computer software. The DMCA is still a major roadblock to fair use.

    Computer programs in the form of firmware that enable wireless telephone handsets to connect to a wireless telephone communication network, when circumvention is accomplished for the sole purpose of lawfully connecting to a wireless telephone communication network. ---- exemption 5, expires October 2009 (source)

  16. Technical Paper on Chairbot Walks You Around While You Sit · · Score: 5, Informative

    I found this interesting technical paper on the robot: Experimental Realization of Dynamic Walking for a Human-Riding Biped Robot, HUBO FX-1. It has lots of pretty pictures and graphs and gets in to the control-system problems they had when they developed it. Each step runs through three different balance control strategies, which they outline in detail. It's almost enough information to build your own!

  17. Re:How about color quality? on MacBook Pro Gets Santa Rosa Chipset, LED Screen · · Score: 2, Informative

    Color gamut reproduction is a function of two things:
    1. the red-green-blue filters used in the LCD
    2. the quality of the backlight.

    Yes, you can create two whites that look identical (same x,y coordinates and therefore color temperature) but have different gamuts. LEDs offer a highly saturated green (and, to a lesser extent, a saturated red). If the filters pass these saturated colors, then the display will look much more vibrant. If you've seen an LED-lit tv in person, the difference is pretty obvious... of course, it all depends on the filters, so I don't know if apple has expanded their gamut.

    Yes, I'm somewhat of a color expert. I designed the equipment that calibrated millions of LED-lit LCD displays for my company.

  20. Re:Not so on Vista Eating Battery Life · · Score: 5, Informative

    That test is severely flawed.

    First off, it's a desktop, measured at the AC adapter. If a standard laptop took 150W, then the battery would only last 20 minutes. Clearly, laptops take less power overall and the differences caused by the CPU's load will be amplified.

    Second, it measures the power at only two points - no load and full load. I suspect that no-load between XP and vista is about the same because they are basically doing nothing. You need a real-use benchmark to compare the two.

    The website says 8-10 hours @ 220v (like your clothes drier uses).

  23. Re:ModeX graphics? Buffer overflows? on What is the Best Bug-as-a-Feature? · · Score: 1

    Ah, the indirect jump bug. It was "fixed" in the 65c02 used in the //c.

    From wikipedia: The 6502's memory indirect jump instruction, JMP (), was partially broken. If was hex xxFF (i.e. any word ending in FF), the processor would not jump to the address stored in xxFF and xxFF+1, but rather the one in xxFF and xx00. This defect continued through the entire NMOS line, but was fixed in the CMOS derivatives.

    I seem to remember that the indirect memory access (not just jumping) had a similar bug, but I didn't immediately find a reference.

  25. Three revolutionary things about Zork on The Ten Most Important Games · · Score: 3, Interesting

    1. Zork understood english sentences. All other text-based games used 2-word commands, like "take beer" and then "drink beer". Zork would understand things like "pick up the beer and drink it".
    2. Zork used an interpreter (Z-code), so the game content was separate from the code. This allowed them to port to far more platforms than their competitors (and back then, there were a lot more platforms!)
    3. Zork was marketed more like a book. When new games came out, the old games remained on the shelves because they still had value. This was a revolution in marketing game software.

    Also, read this. It's a fascinating story about the company behind zork.
