  1. Re:Who needs privacy? on A Mercenary Approach To Botnets · · Score: 3, Insightful

    It's a trifle hard to tell (which is itself a bad sign) whether this is an apologist and/or geek merc, gleefully discussing the exciting opportunities. or a dissident pointing out the absurdly dangerous situation created by a perverse inventive for 'security' entities to tolerate, or even promote, widespread insecurity...

    I don't doubt that there are people who take the former stance; but I'd like to stick up for the latter, and would argue that encouraging insecurity is a hubristic and ultimately self-defeating strategy unless you are the cheap, low-tech adversary, rather than the expensive first-world spook shop with the big, rich, tech-dependent economy behind it.

    Do spook nerds get off on how much of other people's email they can read? I don't doubt it. Are our spook nerds sure that they are so much better than everybody else's spook nerds that they can compensate for the fact that some people (like, oh, the ones they ostensibly protect...) are far more heavily exposed to the internet, and to IT system vulnerabilities in their personal, professional, and financial activities than are less heavily wired countries; but there are few to no countries so poor that they can't field at least a few modestly competent surveillance geeks.

    Why would you knowingly continue a game that everybody can play; but where only some people, you among them, have a significant stake on the table?

    My suspicion is that you'd need pretty alarming (by biological standards) voltages to get significant changes in the behavior of oxygen and nitrogen; and (for some vexing reason having to do with 'practicality' or such nonsense) my shoddy attempt at research was drowned out by the wealth of sources addressing the behaviors of dielectric gasses from the perspective of somebody who wants to fill his high-voltage transformer with one, so I couldn't find anything about viscosity, adsorption, etc.

    That said, when you see that a dragonfly has some truly alarming surface area hidden on the wing surface, has the capability to produce (modest) voltage gradients on surprisingly short notice, you just have to wonder if, deep in the crevices of those nanostructures, the Van der Waals' interactions are sufficiently important that some flight-relevant surface property can be subtly tweaked in parts of the wing during different phases of the stroke.

    If I had to guess, I'd say that it's unlikely; but it'd be elegant if it were possible...

    Lack of ISA could be an issue for certain specialty applications that they'd otherwise be suitable for; but I suspect that they aren't to worried about DOSbox(barring pretty significant modifications to your usual setup)

    I've thankfully not had too much of the pleasure of dealing with them; but x86s running DOS and a suitable control program had a period of popularity as a (comparatively) cheap CNC machine drive/controller mechanism. Typically using the OS as little more than a bootloader, making dubiously safe assumptions about the CPU clock's safety as a timebase for operating dangerous machinery, and driving the actual motor control board by hammering the memory space assigned to the parallel port directly.

    I imagine that, if the incentive were right, a build of DOSbox with the necessary time stability, and some sort of very fast, very predictable, I/O passthrough to hardware I/O pins, all running on a real time kernel, could be made to work; but it wouldn't be trivial.

    What I don't know is how many such applications continue to exist. If they do, something like this is probably a good way to deal with them: DOS is a joke as an actual operating system; but it's ability to get out of your way and give you direct access (or, rather, it's inability to do anything else) means that it hosted more than a few 'Poor Man's RTOS' type applications in its day, exactly the sort of thing that would be most painful to virtualize. If they don't, I have difficulty seeing the point vs. either much more powerful x86s or other embedded options, depending on the nature of the application.

    "..why would they?"

    Because advertisers (while not necessarily the brightest bulbs in the rocket ship) are aware that fraudulent impressions and impressions against irrelevant or downright unhelpful audiences are a problem on the web. Within the limits of their (deeply imperfect) information, their willingness to pay for any ad is going to reflect their belief in the value of the advertising, discounted by the risk that the 'impression' will actually go to a bot, be silently hidden from a user, or otherwise be a scam.

    Every additional point of skepticism among buyers about the quality of Google's ad impressions, and whether or not they are juicing their numbers, makes the job of the ad-sales guys more difficult(or puts pressure on their prices). They don't care about the fact that Google+ is wildly inflated, per se (and that fact doesn't seem to be a big secret to anybody); but if Google's myopic "Google+ at all costs!" focus causes them to start telling little lies about their core products, that would be...problematic.

    For the moment, they seem content with shoving it in the face of every formerly happy user they can find, and generating some seriously optimistic 'active user' numbers, if only because We Cannot Allow A 'Social' Gap! But if it were to get around that Google, themselves, not even sleazy 3rd-party adsense affiliates, were having bots soak up impressions... That's the behavior of the very slummiest ad exchanges this side of malware delivery.

    That is true, licenses don't even enter the picture until you are distributing to parties who would otherwise be unlicensed.

    I was thinking of use cases like the various 'America+NATO Buddies!' shared or partially shared, or one nation with purchases by allies, etc. weapon system procurement arrangements that we've done over the years. In a situation like that, you aren't just dumping it on github; but there are multiple organizationally distinct groups using and modifying the product, each of which probably has a bevy of contractors operating under their own byzantine procurement rules.

    In an instance like that, distribution is still controlled; but having an 'everyone gets to see everyone's customizations on this project' policy could save a lot of quibbling between cooperating parties. Probably wouldn't be accepted for Super Secret Trophy Weapons; but for more mundane utility and logistics (where sharing and common platforms have obvious logistical and efficiency gains, which is why all sorts of things have NATO standards to begin with...), I suspect that it could be a very favorable alternative to doing all the legal and/or diplomatic fighting over exactly who does exactly what parts of the project and who is or isn't sharing.

    I imagine that that's why those bugs are getting away with them. Nothing like being biological to get aggressive self-repair capabilities thrown in more or less for free... Pending nanites, no such luck on our end.

    Marine anti-fouling coatings have similar trouble: they've tried to make less toxic ones, with specially crafted surface geometry that resists mooring by marine organisms; but the minute it starts to wear out, boom, stuff growing. Even the ones that are laced with ghastly organometallic biocides eventually leach enough to lose effectiveness and have to be stripped and re-applied.

    I assume that the crop of 'expensive device connected to ancient computer that runs DOS more or less as a bootloader for a very specific control application' PCs is definitely up for replacement, now that you can put anything up through the mid '90s onto a little solid-state module the size of a pack of cards; but I don't know how big that crop is/was and whether there is much still to be replaced(or even still in production) and how much has already been swapped out for more modern embedded x86 gear or ported and/or replaced by a new product.

    In the absence of a specific legacy, choosing the comparatively small selection of x86 vendors seems odd, particularly for systems too weak to be broadly compatible in the 'but it has to run my Windows stuff!' sense; but I'd assume that these aren't being made purely for somebody's amusement.
