    That's good, what was your fix?

    The primary mechanism for capacitive coupling is a voltage differential from a charge on one side of the pad, and a sink on the other. The trick is that this is not a simple ground mechanism, it's a dispersion. In other words, the meat and ion containing water in the body act as an antennae.

    The fix is to implement the same type of dispersion to couple the other pole of the capacitor. So what you do is embed a conductive mesh below the surface in the "skin" glove of the prosthetic, and attach it to an antenna at the resonant frequency of H-O bonds. Triggering resonance is the same way microwaves work to heat water (and why they are generally not dangerous ionizing radiation), only this time you want to sink the electron transport, rather than sourcing resonance.

    The physical implementation was effectively attaching a 2.4 GHz WiFi antenaa extracted from a laptop to the conductive mesh, and placing it near the surface elsewhere within the prosthetic arm.

    I developed the technique as part of building a robot (at Google) to test gesture recognition algorithms on touch screen devices; the device tracked an recorded human movements on the touch surface, and the robot reliably reproduced those movements on the surface to make the same "human" gestures, in a reproducible fashion. The robot had exactly the same capacitive coupling problems that are present in the prosthetics.

    I imagine that your own touch problem could be alleviated via a conductive glove, of the type used to use touch screens while wearing gloves, with a similar surface mount 2.4 GHz antenna attached to the back of the glove and wired to the conductive layer.

    However... I'd also suggest you check your electrolyte balance -- particularly, potassium, magnesium, and phosphorus levels -- and have a test done for peripheral neuropathy, since an inability to use a touch device as you describe could be an indicator of a medical condition, such as anemia, diabetes, or hypokalaemia (typically a result of diuretics or other medication, but also reduced kidney function), hypomagnesia (stress, alcohol abuse, Bartter syndrome, Gitelman syndrome, dietary phytate or oxalate, etc. -- could be a cause of high blood pressure as well, if you have that), or hypocalcemia (pancreatitus, hypothyroidism -- including that caused by Hashimoto's), or something else entirely.

    Yes, touch screens can in fact be a medical diagnostic tool pointing to other underlying causes for problems. :)

  2. Locality of self. on Will You Ever Be Able To Upload Your Brain? (nytimes.com) · · Score: 5, Insightful

    Locality of self.

    The problem with almost all "uploading" schemes is that it creates a copy of your brain structure, so it's a copy of you, rather than you. Externally, there might be no apparent difference to an outside observer, but internally, you're kind of dead, if that 1 cubic foot of meat space is no longer functional.

    The only hope of an upload of the actual "you" would be an incremental replacement of brain structure, such that you lived in both meat-you and electronic-you at the same time, until the electronic-you completely replaced the meat-you, without a loss of continuity of consciousness.

    Otherwise, you're just building pod people. Which could be useful, if you wanted to embed one of them in a starship (or more likely, a tank or other weapon of war), or if you wanted to make a lot of duplicate copies of a particular mind, and didn't care about their locality of self, either.

    Okay, so I'm only sort of guessing where you were going with that. However, no... No you shouldn't slow down progress because some can't keep up. For some reason my 'touch' doesn't seem to work well on most every touch screen. I accept that.

    Bad guess, dude.

    There's a difference between being *able to* engage certain sensory and motor systems in order to interact with our devices, and *requiring us to* engage certain sensory and motor systems in order to do so.

    P.S.: I came up with a "fix" for the capacitive coupling problem and posted it to a prosthetics forum, rather than being an asshole and patenting it. Numerous people have thanked me for it being the first time they've ever been able to use a trackpad (and so on).

    You end up spending ressources to undo what someone did with an automated script

    You are presuming that I do not hire them to implement an automated script to go on a seek-and-destroy for *ALL* the compromised systems attacking mine. I'm well aware of amplification techniques. Doing that, however, risks attacking intermediary systems in the same jurisdiction as yourself, which tends to be more legally dangerous, if a connection is ever proven. But if the government isn't willing to go after the perpetrators of a botnet, they are even more unlikely to go after a company engaging in this type of tactic. If the government couldn't/wouldn't stop the original when a large company was complaining, they are much less likely to go after the company.

    Either way, we appear to be on the verge of legislation which authorizes such things, in which case doing that would no longer be illegal. The competing idea is a new national law enforcement unit whose purpose is to do it on behalf of complaining U.S. companies. We will likely end of on one of these paths, sooner, rather than later, should another attack on the order of the OPM hack occur. If that happens, it could come together rather quickly, up to and including requiring broadband providers to include government use DDOS tools in Comcast routers (for example).

    There is no defence.

    Back up. That's only true if we are talking intermediaries.

    I know a number of executives at multinational corporations that, should the original perpetrators of an attack on their companies be identified, they'd have one of their "corporate fixers" go and "handle it". So there *is* a defense, it's just rather extreme, and generally pretty extralegal, up to and including *very* extralegal. As long as it wasn't someone who was government related, or prominent in some way, governments generally look the other way when multinationals do stuff like this, and I expect that it happens even more frequently when banks are involved.

    This has already happened, in extremis, several times in Russia already.

    You have a problem with language semantics. Obviously, the definition of "severe problem" you use here is something you dreamed up, and incompatible with general use.

    severe /svir/
    1. harsh; unnecessarily extreme: severe criticism; severe laws.
    2. serious or stern in manner or appearance: a severe face.
    3. grave; critical: a severe illness.

    Yes, copyright laws are indeed severe. However, violation of copyright does not lead to death, like the severe flaws in the Toyota ECM software, so in that sense, unlike a severe illness, a violation of copyright is not severe in the same way the Toyota ECM software or an illness can be considered severe.

    And, incidentally, if discovered, it becomes a severe problem for those that wrote and own the software and possible those that use it. Fro example, it could then become subject to criminal penalties (i.e. personal ones) to continue to use the software.

    China regularly ignores patent and copyright law, and if the only way to expose such violations would be to provide source code (it's not: companies are just lazy about reverse engineering to determine copyright violations -- which, since it would not be in the interests of interoperability, would be a DMCA violation -- just like the DMCA violation the CARB and the EPA committed to determine that VW was cheating on the smog tests, in fact), then a company would have to be stupid to ever expose their source code.

    BTW: The only penalties for a Chinese violation of a patent or copyright are ... nothing.

    As for those who use the software: ATI and nVidia have basically agreed to not look inside each other's sausage factories. If you are a user who goes looking and finds something, expect to be sentenced for violating the DMCA, and then expect hate mail from everyone who can no longer use the product, because you've exposed the internals of the sausage factory.

    The main problem is finding a disposable expert.

    The people who originally clean-roomed the IBM BIOS for Compaq were split into two teams, with a Chinese wall between them: the analysis team, and the implementation team. The analysis team analyzed the IBM BIOS, wrote a specification, and then the implementation team implemented a BIOS to that specification. At which point the analysis team were effectively "burned", as in being forever barred from ever working on an implementation team in the future. They were highly paid for this, but they were disposable.

    As with clean-room engineering, this expert would not be permitted to work on any software covered by the trade secret in the future. In an expert witness situation, you might be able to get away with disposing of the expert, if all they did was witnessing, rather than actually coding in the field of expertise themselves. However, how likely is it that you can find someone like that who also qualifies as an expert?

    Further complication: Having testified (presumably in favor of the prosecution, in this case), would the expert witness be permitted to testify on similar goal programs in the future, given what the [now] knows about the process and techniques of the one they testify about today? Would exposure to multiple, competing trade secrets, damage their ability to perform an unbiased analysis, given what they knew from earlier experience? In general, I think you [as the defense] could argue that it, in fact, did damage their impartiality in their analysis.

What we are probably seeing is them about to do a roll-out of exactly that, and the current moderator staff scaled back to the point that they only have to deal with explicit moderation and tweaking of the automoderation software, for things which fall through the filters in the wrong direction, either pro or con.

    My suspicion is that there was an internal "secret project team" utilizing "big data" techniques until they ended up with a trained-up model that (mostly) ended up with the same answers as the human moderation teams, and they are doing this concurrent with a roll-out, and will decide how many people to let go, subsequent to growing pains.

    They should have cold temperature relief valves, and use PEX piping, so that it can freeze without damage. The building itself should be equipped with an excessive flow shut-off valve, such as the Dorot 100FE (which is an entirely mechanical design, mediated by water pressure differential over time).

    Then they could leave the water on, and not have a problem.

    BTW: if they had excessive flow shut-off valves throughout the system, the broken water lines would never have risen to the level of a problem in the first place; the first they would have heard about it would have been complaints of not water.

    The reason that a fire hydrant doesn't freeze is that there's no water in it; it's called an "anti-siphon valve" and it's located below the frost line. When water is shut off, the valve drains the water out of the plug; the same thing should be employed in structures so that when the excessive flow cut-off triggers, the water drains out of the system, and it's protected against freezing.

    You could literally abandon a properly equipped building for yeas, it'd get close to the freeze point, and the entire plumbing system would protect itself.
