  1. Re:Reasons why I don't like Musk's hyper loop on SpaceX Is Building a Hyperloop Test Track · · Score: 0

    Another false analogy. The chunnel is not hermetically sealed, and reduced pressure. It has an additional service tunnel. And trains are not the size of a metal coffin.

    [T]he device doesn't contain any onboard air supply . . . if the device loses power for any reason (electrical, mechanical, computational) then you better be able to hold your breath for a long long time.

    Solution: Add an emergency air supply.

    Worst case scenario: So the problem capsule stops halfway between LA and SFO. No problem, the tubes are running along the freeway, so are easily accessible by heavy equipment. But this occurred on a foggy day and there was a huge pile up on both sides of the freeway and all lanes in each direction are blocked - so no emergency services can get through.

    Now how large are you going to size that emergency air supply?

    The seats are actually quite roomy - check out the dimensions in the Hyperloop alpha document.

    Claustrophobia has nothing to do with seat size. Imagine a failure mode where the power goes off, the screens die and all movement stops. And the only way to get out is someone on the outside with a power saw.

    Yes, it does. Section 4.5.2. Same system as on an airplane.

    And where do you think airplanes get their oxygen from? Its called the outside atmosphere. If a plane stops flying it descends to a lower height with a breathable atmosphere - something that the hyper loop can't do. And emergency oxygen in planes is predicated being able to descend to a safer level. So once the capsule stops the clock starts ticking until you run out of air. In this case the capsule is more comparable to a submarine than a plane.

    It's two tubes, one for each direction. In the event of a long term outage, the one open tube can be periodically reversed to allow traffic in both directions, at a cost of throughput.

    Still sucks to be stuck in the tube with the issues, and at 5 minute launch intervals, there will be a lot a of people in the same boat.

    All capsules have mechanical braking systems and are spaced five minutes apart, automatically triggered in the event of an obstruction. They also all have powered wheels for low-speed travel. Section 3.5.2.

    And the capsules are designed with a power budget that only covers the duration of the trip. They can't even accelerate to speed by themselves. Once they are stopped, the only way out is that worker with the power saw that I mentioned above.

    It'd be nice if you'd read the document before complaining about the concept.

    I did read the document several months ago when it was on here. I read it all in order to understand what it was about. And nowhere were any of these failure mechanisms addressed.

    1. All the diagrams give the impression that it will be like people flying through tubes as in Futurama. Instead you will be sealed inside a metallic "bullet", that runs in a metallic tube - no windows for you (sort of like James Bond in The Living Daylights). It's a pity if you have any sort of claustrophobia.

    2. While the device doesn't run in a complete vacuum, it runs in an atmosphere that is low to the point of being unbreathable. But the device doesn't contain any onboard air supply - instead it relies on the driving compressor/fan assembly to compress the air to a human sustainable amount. So if the device loses power for any reason (electrical, mechanical, computational) then you better be able to hold your breath for a long long time.

    3. There was no indication that the loop itself was anything more than a single tube. Thus there is no capability to bypass any section. So if a device fails, all devices that are already in transit and behind it are screwed (see 2 above).

  5. Location services? on Santander To Track Customer Location Via Mobiles and Tablets · · Score: 1

    Can't you just switch off locations services for that application? I thought that both iOS and Android allowed you to do that (albeit in different factions).

    On the other hand if they can grab location services data without the OS knowing - then that bank/app needs to be shamed.

    On the third hand. Doesn't just collecting the IP address you are logging in from count as collecting location data?

    You can already vary the power, it's called a valve. As for the complexity... How is an EM railgun system ANY less complex than a (at its core) a tube with a valve and a hook on a slug?

    From what I understand, any form of structuring is illegal.

    Structuring is manipulating the amount of cash to evade detection by authorities. $10k USD requires a mandatory report by FinCen, but that's on deposits. I'm not sure there's any mandatory reporting on withdrawals, so I'm not sure why the FBI would be interested. It's not money laundering if you're withdrawing money from your bank account.
