    Just use a high voltage burst to be released through the electronics. (High voltage in this case can be less than 50V, since most chips in phones runs at just a volt or so)

    If This Goes On/Revolt in 2100 by Robert Anson Heinlein. (The backstory to that story is more concerning the question, where the First Prophet was Nehemiah Scudder, a backwoods preacher turned President (elected in 2012), then dictator (no elections were held in 2016 or later)

    You can read Heinlein as adventure stories, you can read his stories as idea experiments and you can also read his stories as reflection on humanity.

    Even though the world isn't what Heinlein depicted I still have a feeling that the real life Nehemiah Scudder is waiting around the corner.

    You can instead see that space as an area which is open for everyone to experiment in, sometimes those areas are useful for trying out various technologies without the risk of interference to commercial services.

    Most of the bandwidth consumption today are from smartphones where the users are surfing the web, which means that it's not really any productive use. There are ways to lower the load on the phone networks, and some of them are spontaneous - like wireless access points available on restaurants and other public places. The cells for wireless access points are relatively small, so even though that band is crowded it's generally not a problem with interference.

    This also brings up an alternate way of mitigating the bandwidth problem, and that is to create smaller cells for the mobile phone networks in "hot" areas like shopping centers and transportation hubs.

    It's when the resources are limited that invention of new more efficient ways are inspired.

  10. Re:Rock, not dirt on Why Is US Broadband So Slow? · · Score: 1

    I have a friend that lived in Westford, and I know what it looks like. I don't say that all of it needs to get buried, but a step by step operation.

    And you already have gas pipes buried in Westford, so it's not impossible.

    Maybe it would be good to look how it has been done elsewhere. A lot of small towns around Sweden have similar soil conditions to Westford.

    In any case - what I was trying to show is how ugly it gets with all those wires on utility poles.

    What's more worrying is that a lot of farmland is going away if there's a rise. And a considerable amount of the farmland in California may suffer.

  12. Differentiate between channel and service. on Why Is US Broadband So Slow? · · Score: 2

    I think that the problem here is that there's no differentiation between the fiber itself and the service carried by it.

    If a town lies down dark fiber and then lets the end customer choose operator using that fiber, then it wouldn't be a big problem.

    As for putting fibers on utility poles - that's stupid for several reasons - risk of damage is high, complex arrangements on poles means high risk of conflicting wiring and it really destroys the general view of a small town having the air filled with wires crossing all over the place.

    Compare Westford, MA, USA with Kållered, Sweden.

    It may be more expensive to bury the wires, but it will lower the costs in the long run.

  17. Re:Never use any software. on Stack Overflow Could Explain Toyota Vehicles' Unintended Acceleration · · Score: 1

    You can use recursion if you have something that terminates it.

    A stack overflow detection should definitely have been in place causing a termination/restart of that thread/process.

    However this highlights that many ECUs in cars today are built by "embedded standards" where there are weak protections between processes because they use proprietary operating systems that seldom sees the extremes but instead relies on "nice" programmers following the "rules".

    The main issue is anyway that the car industry today tries to save a cent on hardware and add a large load on development. Most notably is that many ECUs in cars today aren't able to do floating point calculations in hardware - they require software workarounds one way or another because a processor capable of floating point operations costs more.

    The ISO 26262 standard will put more demand on the vehicle industry when it comes to software quality.

    It depends on if the ABS and/or brake servo is influenced by the bug and makes it harder to apply the brakes.

    Be aware that most brake servos are using the manifold vacuum to increase the brake force. If the engine gets full throttle the vacuum is soon depleted and a much larger force on the pedal is needed which will be experienced as failing brakes.

  19. Re:OTA seems excessive...How about USB? on Why Your Phone Gets OTA Updates But Your Car Doesn't · · Score: 1

    The car manufacturers these days makes more money on aftermarket service programs than on selling the cars themselves.

    That's one driving factor.

    Another factor is that many modern cars today runs only CAN buses which are very slow, and they don't want to go Ethernet because it's seen as dangerous and unreliable. This means that an update of an ECU can take 30 minutes to download, and a modern car today have between 10 and 70 ECUs - this means that a major upgrade is time consuming, and the car can't be used during that time.

    Manufacturers like Tesla don't suffer as much from the legacy of CAN and Autosar so they can pick a much more modern approach.

    If you get things too tight you will lose some viewers. The point is to have some parts where the viewer can have a pause and get the wider perspective before you dive into the deep again.

    People today are too stressed to really relax and take a wider perspective from time to time.
