  1. Microwave ovens only need to block the frequency used by the magnetron (& enough to the sides to account for drift & finite-time effects). It is apparently tricky to make a broad-spectrum Faraday cage with a usable door, so they tend to take the cheapest option & leak elsewhere (i.e. everything but (part of) the 2.4 GHz Wi-Fi band).

  2. Re:Its a step, but there are better ones on Edward Snowden's New Research Aims To Keep Smartphones From Betraying Their Owners (theintercept.com) · · Score: 1

    This. The comments suggesting just disconnecting or disabling the radio are missing that the phone could record stuff & transmit it later when re-enabled. An RF sensor will not stop such recording, either.

    Sensors could have small, redundant backups, so hardware input switches might only get a false sense of security. For that matter, even removing the battery is in principle possible to work around (using an extra battery or a capacitor—the power needed to record from a microphone is not very high, for example). We might hope that would not happen due to cost, but what is a few cents out of the price of a modern smartphone?

    A soundproof Faraday cage should work, but if someone is that paranoid, they probably need to put the people inside it rather than their phones.

  3. Re:What if the robots don't want socialism? on Europe's Robots To Become 'Electronic Persons' Under Draft Plan (yahoo.com) · · Score: 1

    There is a difference between a human of above average intelligence needing the rest of civilization to survive &, say, a human needing an ant colony. (Sure, they do something useful, but we kill them en masse when they get in our way.) So it would seem to depend on how much more advanced than us these hypothetical robots were.

    If they are more rational (for certain values of "rational"), they might be socialist while sub-human, then switch to being libertarian once they reach super-human intelligence. But of course that assumes they are programmed such that they can pick their political views, rather than being constrained to espouse whatever position most benefits their owners.

    I hacked the PS4 camera firmware to get it to work with my apparently-buggy USB 3.1 controller card. You still have to unload & reload the driver every time you want to use the camera (or even change resolution or frame rate), but it does work. Sometimes. (I suppose I could have hacked the USB controller's firmware instead, but it does not seem to be reloaded every time it powers up the way the camera's is.)

    While the standard way of quoting the size is ¼" (& that was surely what was originally specified), that is exactly equal to 6.35 mm, unlike many other claimed (near-)equivalences between metric & U.S. units.

    But for exactly that reason, it might as well be called ¼" because it is a more easily memorable number.

  7. Re:Say "Citigroup" instead of "Thank You" on Citigroup Sues AT&T For Saying 'Thanks' To Customers (techdirt.com) · · Score: 1

    I was not aware of that specifically, but that is irrelevant to the point I was making. I was only talking about how people think some brand names are too generic. If they complained that Apple Computer should not be called that because "Apple" is a dictionary word, then I do not see why they would not have said the same about Apple Corps, & vice versa. That the latter sued the former for having a similar name & working in the same area is not the same thing as whether (random people think) "Windows" is too generic a name for a windowing environment or "App Store" for an app store.

    It is more like "Android" for an OS or "Oracle" for a database company, unless people actually start using Android to run humanoid robots or asking Oracle to predict the future (which should still not affect their non-genericity with respect to cell phones & ordinary databases, respectively).

    Sure, but that (2 companies having similar names) is different than people saying "Apple" is too generic a name for a computer (or record) company would be.

    Well, people (used to?) complain a lot about "Windows" & "App Store" being too generic. Somehow I never seemed to hear anyone complain about "Apple," though—probably because, despite being a dictionary word, it has nothing inherent to do with its subject matter.

    There are also places in the US where you are not free to express your religion. E.g. some schools not allowing prayer (at least in forms that makes it apparent to others that one is praying). & we all know what some in the government seem to think of the rest of the Bill of Rights.

    Except that each separate app is bigger than the original app was when it did all the things (& I have yet to actually use any of the new features, as far as I can tell). It has gotten so big that my phone crashes (the OOM killer takes everything out, eventually including something-or-another important) if I attempt to install any recent version of the main Facebook app (whereas you would think separating the parts would have fixed that). I would say it must be because I have too little RAM, except that everything else seems to fit & work just fine.

    Perhaps self-representation should be measured based on the larger of how much they would have to pay for representation of similar competence & how much their time would be worth if they were not in court? (Probably still loopholes here, but it should still be greater than $0.)

  13. The idea is to prevent getting the master password (which still needs to be secure by itself) from a per-site password. If SHA256 has the relevant security property (inability to find a common prefix given several partial hashes & the suffixes used), this should be as good as using a list of random passwords secured by a master password, while taking less space & being reconstructible.

  14. Either use xkcd's mnemonic technique, or a shorter but randomly-generated sequence of characters, & memorize it. I am not sure which is more resistant to shoulder-surfing, which is probably the relevant consideration if you ever need to log into something in public, since you (hopefully!) only have to change it very rarely.

    It might broadcast itself to a nearby Internet-connected device by careful modulation of some sufficiently-long trace on the circuit board. People have managed to broadcast AM radio from graphing calculators (first example that came to mind), so it does not even require superintelligence. Now, maybe if you put it in a Faraday cage + audio shielding, it might require more intelligence to get out, but even then I would not expect a superintelligence to fail to find a way out.

    That it should not choose to activate the kill switch is also important (mentioned in the abstract, which is in turn quoted in the article).

    You can block message notifications on the desktop site & on the version of the main Facebook app I have installed (which is so old as to have working contact sync on Lollipop & built-in messaging), but people can still send you messages & wonder why you are not replying. I had the same problem with text blocking before we had unlimited texting...people (& more worryingly, businesses that I had never authorized to text me about things like stuff being ready to pick up) expected that I had seen their messages, but they were silently dropped somewhere before my phone. Probably the intent is that, by letting the messages accumulate unread, they can pressure people into unblocking the notifications & installing the app.

  18. In at least one of his books (the one that came out in 1999, maybe? Or maybe the one after that), I seem to remember him making this prediction with this year. I cannot check as my copies are somewhere else right now. But at least he did not make it up too recently.

    Some universities go so far as to have deals with Google to use Gmail for E-mail addresses under their domain (& probably other Google apps for whatever their purposes are).

  20. I just tried pasting ESC [ A (with character 27 in place of ESC & without the spaces) into a terminal, & it switched to the last history entry (& kept going back with more pastes). That may be the sort of escape sequence that was meant. So keyboard commands for terminal-based applications (someone mentioned there is an example exploit for vi) should work.

    Hyperbolic space is locally Euclidean (as are all other manifolds), just not globally Euclidean. Locally non-Euclidean spaces are weirder.

  24. Even worse is when something is available online for free with commercials & they get the timing off...then you see or hear a second or so of whatever was about to happen, then have to wait for the ads to end to see the rest. Sometimes it is hard to remember half a word from 10 minutes ago (especially if you go do something else on the commercial break). (10 minutes because 3 minutes worth of ads expanded by the ads being forced to a higher bitrate than my link can support, even though the show plays just fine...you would think they would realize that nobody is going to even try watch an ad that stutters that badly.)

    TMS does not need nearly as high of levels as an MRI machine to have a measurable effect, so the pattern & not just the amplitude matters for magnetic fields in addition to audio. I meant that inducing magnetic fields strong enough even to have a TMS-like effect on the brain using just microwaves (rather than an electromagnet as in actual TMS hardware or an MRI machine) might require dangerous RF amplitudes, not that high levels of magnetic fields were dangerous on their own.
