  1. Yup on What's Killing Your Wi-Fi? · · Score: 1

    I've got some Wifi problems in my apartment. In the room with the AP, everything is fine. In the next room, transfer speeds are in the toilet. I used 'WLAN AP Grapher', which gives a graph of signal and noise over time, but that indicated no change in the S/N ratio between rooms. This rather surprised me. If there's interference, there should be noise in the frequency range used by the WLAN.

    And on that note: anyone know of a tool for OS X that shows WLAN speeds in a graph ?

  2. stars visible before the sun is gone on Time Lapse Video of the VLT In Chile · · Score: 1

    What surprises me about the first scene of the video, is the amount of stars that are visible while the mountains are still bathing in light. In fact, the number of visible stars at the top of the video doesn't change much during the progress from dusk to night.
    For a moment, I suspected the uploader of superimposing a night sky image on a local sunset. There must be a better explanation, but I can't find it.

  3. They should add a wing on Martin Jetpack Climbs 5000 Feet Above Sea Level · · Score: 4, Interesting

    The pack is big and bulky enough that the addition of a small wing won't make much of a difference. With a wing, you can transition from vertical takeoff using thrust only, to horizontal wing-borne flight which uses much less power (and/or achieves a much higher speed).

  4. Compared to Shinkansen or airplane on Japan's MagLev Gets Go Ahead · · Score: 5, Interesting

    TFA mentions 67 minutes travel time. The Shinkansen takes 155 minutes for the same distance, so this would be a significant improvement. The cities are 500 km apart, even an airplane would not take significantly less than an hour.

  5. Re:Why PDF? on Alaska Airlines Jettisons Paper Manuals For iPads · · Score: 1

    Navigation charts are an example of information that can benefit from being put onto a computer. The computer can overlay the chart with all sorts of information that you need, but can't necessarily find on a navigation chart, like the navigation plates you mention.

    The next step would be to provide a GPS input to the reader, so it can place a position marker on the chart, and e.g. automatically pull up the correct navigation plate for the airport you're currently on.

  6. Why PDF? on Alaska Airlines Jettisons Paper Manuals For iPads · · Score: 1, Interesting

    OK, I know why. PDF is easy to create, and they probably already had the documents in PDF formats anyway.

    But if they want to do it right, they'll need to at least create PDFs in an iPad-specific format (page size and font size optimized for easy reading, without having to scroll on the page).

    Better yet, don't use PDF at all but a format more suited for digital documentation. Even HTML would be a step up.

  7. Re:Fuck Paypal. on PayPal Accuses Google of Poaching Mobile Payment Trade Secrets, Personnel · · Score: 1

    You're forgetting that checks don't work so well for international transfers.

  8. Natural outcome on Sprint Pushes FPS NOVA With Firmware — and Users Can't Remove It · · Score: 5, Insightful

    This is what you get when the gadgets are given away or subsidized. Abuse will ensue to make sure the provider recovers their costs.
    On PCs, at least the shovelware is generally removable, and you have the option to buy a nonsubsidized gadget that doesn't have crap installed. In the US phone market, usually the gadget and service are provided by the same party and the abuse includes locking down the OS.

  9. Re:Worst part on 8000 Credit Cards' Details Compromised In Australian Bank Breach · · Score: 1

    Interesting. My bank has a policy of never contacting its clients via email. They made a lot of noise about this last year when a number of phishers tried sending emails to the bank's clients.

    Instead they use either snail mail, or the bank's internet portal (which uses a challenge-response mechanism linked to my debit card so it's reasonably secure).

  10. Why fine the bank? on 8000 Credit Cards' Details Compromised In Australian Bank Breach · · Score: 1

    TFS mentions that "Mastercard and Visa may issue penalties including fines to the acquiring bank ". Why is that when the breach didn't occur at the bank, but at a merchant?

  11. Re:Good thread with an Airbus pilot and some exper on Flight 447 'Black Box' Decoded · · Score: 1

    It surprises me that things are set up this way. These flight control systems are set up as multiple-redundant systems, and yet a single failure (pitot tubes icing up) can lead to an information blackout.
    Also, it's still possible for the instruments to give incorrect information because they rely on sensors that measure secondary effects (e.g. altimeter based on air pressure, measuring height above an assumed sea level instead of a direct altitude measurement by radar).
    It seems to me that there should be a second, independent path for the essential information (position, attitude, speeds in all dimensions). I know GPS has its faults, but it would provide a useful backup for position and speed and give the pilots more information than the primary instruments can. That leaves attitude information, you can use a gyro-driven artificial horizon for that.

  12. What is this? /. Gossip? on Zuckerberg Only Eating Animals He Personally Kills · · Score: 1

    Rumors for nerds. Stuff that doesn't matter.

  13. Time for the Moron Decree on Unabomber Property Up For Creepy Online Auction · · Score: 1

    Instead of giving such criminals a name (or worse, a nickname), it's time we start referring to them as "Moron # (sequential number)" and generally not giving them the attention they crave. No more notoriety!

  14. Re:Walled garden on Amazon Challenges Apple With Mac App Store · · Score: 1

    You'll notice that those switches were whole hog: they didn't sell PPC and 68k machines next to each other. They did during the PPC-Intel transition, but only briefly, and again using an emulator to run PPC software. The switch to OS X was done by allowing people to run old software in an emulator.

    I don't see them going with an ARM and then wasting 50% of its processing power running an x86 emulator.

  15. Re:age on Student Finds Universe's Missing Mass · · Score: 5, Insightful

    Perhaps more surprising is the prof's willingness to share credit for the discovery with his student.

  16. Re:Walled garden on Amazon Challenges Apple With Mac App Store · · Score: 1

    I don't see Apple splitting their Mac market into Intel and ARM offerings. They'd be shooting themselves in the foot, offering a computer for which all software must be recompiled.

  17. Photocopied? on ATM Repairman Accused of Taking (and Faking) Cash · · Score: 2

    Aren't color photocopiers supposed to give an error message when you try to copy a banknote?

  18. Re:Walled garden on Amazon Challenges Apple With Mac App Store · · Score: 3, Informative

    Mac users have been able to download software from websites ever since the first modem became available for the Mac. This has never been a problem for Apple, so why start now? Not saying it's impossible, but IMO very unlikely.

  19. Re:Walled garden on Amazon Challenges Apple With Mac App Store · · Score: 0

    What DRM plug? Apple has no way to stop people from downloading software from a website.

  20. Not an app store on Amazon Challenges Apple With Mac App Store · · Score: 4, Insightful

    Apple's App Store provides a centralized update mechanism. Amazon's store is just a website.

  21. More of this is needed on FSF On How To Choose a License · · Score: 1

    I recently did some editing on Wikipedia, and came to the issue of licensing my contributions (in this case, photos). I could choose between a dozen licenses, and figuring out the differences between them made my head hurt. The license-choosing process was way more involved than the upload itself, so I gave up and chose the recommended license. I understand the importance of making materials available so others can use them, but does it have to be this complex?

  22. Re:Why no stay with barcodes? on Finding Fault With Qantas' RFID Baggage Tracking System · · Score: 2

    Yup.
    National Geographic has a documentary (in their 'Megafactories' series) about the UPS hub in the US. It shows that a large fraction of the personnel there has a single task: orienting boxes so the label can be read by the scanners.

  23. Codec as the weak point on Chapel Hill Computational Linguists Crack Skype Calls · · Score: 1

    TFA states that this is possible due to the codec that is used:

    the best...compression for voice data makes use of the structure of speech

    So using a not-optimized-for-speech codec (e.g. mp3 or wav) would defeat this.

  24. Re:Why are nuclear plants so hard to shut down? on Fukushima To Become Nuclear Dump? · · Score: 1

    There's not much space inside the reactor vessel, so you can't separate the fuel rods by much.

    Also, separating the fuel rods isn't going to decrease the amount of energy that's produced. All of the energy still goes into heating up the reactor vessel and its contents, so you end up with the same problem.

    You're better off designing a more failsafe cooling loop.

  25. Re:Now I'll have to visit Bletchley again on Tunny Code-Breaker Rebuilt At Bletchley Park · · Score: 1

    That's unfortunate. I've been a couple of times, and had a knowledgeable guide each time.
    In winter, they have a small staff on weekdays, so not everything is open and you may get a dull guide. Weekends are better. Or go during the summer.
