    True, true. I really should have said that Apple is the owner; but makes it very difficult for its vassals to enforce any restrictions on their vassals. Everyone is supposed to be a direct vassal of Apple, with only the most token support given to situations where somebody wants to farm out a large quantity of iPads to people under their organizational control.

    Umm, this article is about 'gas' as in 'natural gas', not as in 'gasoline'.

    And, as it happens, one of the things that utilities like about combined cycle gas turbine units is that (by power plant standards) you can knock 'em together extremely quickly and cheaply, and once constructed, you can ramp them up and down very quickly indeed.

    It's kind of nuts that natural gas is cheap enough that these things would be competing with base-load units; but natural gas plants have been the peaking-load choice for years.

    It sounds like the school districts (either because their IT staff are monumental idiots, or, probably more likely, because nobody budgeted in anything for "device management" because 'Hey, iPads are easy!') were just using Exchange activesync restrictions, which are... more or less worth what you pay. Delete the (probably boring) school email account, and away you go. By Fucking Design.

    The various Apple-blessed 'MDM' services (either 3rd party contract types, or in-house on the ridiculous hardware that Apple calls 'servers' these days) are incrementally more robust; but iPads are fundamentally aimed at 'user-is-owner' scenarios, with Apple occasionally throwing a crumb and a contemptuous sneer in the direction of anything else.

    (Incidentally, that's one thing that surprises me about 'WinRT'. Microsoft, fuck man, You Could Have Had The Tablet With Native Active Directory Support. But you didn't. You voluntarily removed that feature. Are you totally insane? That's one area, at least, where you could have blown the pitiful excuses for 'device management' in the competing ecosystems to hell and back; but no.

    I suspect that you could do it (if nothing else, cheat: anti-drug vaccines are a big area of research, so you can probably find somebody to sell you antibodies targeted at any of the major ones, at which point you smear it on a slide and work out a means of detecting antibody/antigen binding...); but that would probably be a good way to discover the other major virtue of animal olfactory systems:

    With rather limited exceptions (certain contact anesthetics will temporarily knock the sense of smell offline, cocaine included if memory serves, and contact with something nasty enough to physically damage the sensory cells: eg. occupational ammonia exposure, squirting zinc solutions up your nose, will eventually toast the sense of smell entirely), organisms are pretty good at self-cleaning. Once exposure to a scent stops, the olfactory system is back and ready for action in short order. Whether this is because it employs some fancy non-binding mechanism, or because 'cells' are the closest things to sci-fi nanites that we know of, I don't know; but it works.

    Antibody or chemical-reaction based systems are inherently consumable, and such specialized electronic gas sensors as do exist can be vulnerable to 'poisoning' by environmental contaminants. (Among the more obnoxious, catalytic methane sensors are poisoned by silicone vapors, as found in about a zillion elastomers, lubricants, and all sorts of other things. Just something to keep in mind if you ever find yourself in a coal mine... A poisoned methane sensor is indistinguishable from a methane sensor that just isn't detecting any methane, so replace regularly and avoid sparks and open flames.)

    I find it remarkable and interesting that we still can't or at least not easily produce eith sensors the sniffing capabilities of these critters.

    Aside from the fact that the answer would more or less inevitably involve some you-have-fun-fabricating-that micro to nanoscale arrangement of chemical receptors, we labor under the considerable difficulty that we don't really know how scent works.

    With something like sight, it's possible to work more or less entirely independently of any real understanding of the eye, human or otherwise, because things like 'primary colors' and color mixing actually work pretty well at handling a wide variety of real-world problems and are simple enough that a decent art curriculum probably covered them before you finished high school. There are certainly horrible complexities ('metallic' isn't a color; but it certainly is a recognizable optical phenomenon, also, please characterize any deviations from the expected result when I take the idealized 24-bit RGB image displayed on my non-ideal 8-bit RBG monitor and send it over to my printer, using CMYK inks...); but 'just put a photosensitive material behind an array of R G and B filters' does actually work. If you proceed to brute-force the hell out of it, it works even better.

    With something like scent, we know about plenty of strong and distinctive scents; but nothing 'primary'. Mixing is somewhere between unintuitive and pure black magic, prediction from chemical structures(even if perfectly well defined and provided in whatever form you prefer) is quite difficult outside of a few very well known areas, it's a total mess. Certainly, our ability to (cheaply and quickly, and from very small samples) analyze chemicals in the environment isn't as advanced as we would like; but even if it were, it's not as though we can see ourselves progressing toward the smelloscope, with some technical limitations (as we could in the early days of photography, were basically everything sucked; but basically everything was also precisely analogous to its better-refined contemporary chemical film systems), we'd just be better at identifying molecules flying around in the air.

    It clearly isn't a safe default assumption (since it was wrong in this case); but biochemistry is loaded with "Oh, yeah, this molecule is a pain in the ass to synthesize, unless you have this totally elegant catalytic protein, as organisms that use it do" and has fewer well known examples of 'Eh, breaks down under UV; but it'll be fine once the radiation stops'.

    Would it be in any way adaptive for hormones themselves(which disruptors are often very similar to, hence the ability to neatly disrupt the endocrine system) to have this level of durability, or is it much more likely that it's mere chance, biologically irrelevant until we started pumping the things out on an industrial scale?

    Theoretically (especially for 'release promotion' type stuff, where longevity is not a concern and awful 'analytics' people are probably salivating over the numbers) the plan might call for a server-side component(which would allow both tracking of interested users and allow the bittorrent-distributed component to be incomplete and thus not crackable on its own). That wouldn't stop the trivial redistribution of de-crippled copies once one person takes one for the team and complies with the demands of the package; but if 99% is distributed as a torrent, for cost reasons, and the last 1% has to be obtained from the TLS-authenticated server of the distributing party, it might not be possible to open the package without jumping through whatever hoops that server stipulates.
