  1. Overselling peak bandwidth is fine on Bittorrent To Cause Internet Meltdown · · Score: 4, Interesting

    Mislabeling it is not. If you sell 1MBps with a 25GB/month cap, then you need to be advertising your "1MBps peak bandwidth, 0.01MBps constant bandwidth" service, not misleading your prospective customers.

    Practically every ISP should be overselling peak bandwidth; because people don't all use it at the same time, your only choices are to let them use as much as they can (overselling) or to throttle them. But both peak and aggregate bandwidth are important; if you're not providing much of the latter you shouldn't get to imply otherwise.

  2. Re:Not Really on Should Taxpayers Back Cars Only the Rich Can Afford? · · Score: 1

    I suspect it would be pretty difficult to find anything in the constitution that would go against using money from a bill that passed Congress to do what the bill specified.

    Try the Tenth Amendment.

    Of course, even before the Bill of Rights it was understood that the Constitution was a "white list" of enumerated powers which didn't give the Federal government authority to do anything not spelled out explicitly. But some paranoid people thought that it would be necessary to make this philosophy clearer. Apparently they still weren't paranoid enough.

    I don't mean to say that the Constitution's white list isn't too limited. Competing businesses and governments have "Prisoner's Dilemma" type incentives to slack off on basic research, making such funding an excellent candidate for Federal intervention. But it would have been nice to have an actual Constitutional amendment adding that power to the list. Our alternative strategy of reinterpreting the Constitution to read "Congress can pass any bill which, in their own opinion, promotes the general welfare" has had a history of backfiring badly.

    Yes... but if you can literally print money, if you're in a deflationary spiral that would overwhelm the inflation inherent in printing money, and if that deflationary spiral is making everything cheaper, then now might actually be a good time to pick up a few vacation bargains.

    We have to balance the budget. Eventually. In a time-integrated sense. Now is probably the worst possible time to start.

    On your other point: unless "privatization" is code for "use the same amount of government money to buy from the best private suppliers", then it would actually turn out to be code for "shut down the space program". There's enough Rich SOBs out there to support some Mach 2.5 suborbital hops, sure, but not enough unassisted to pay for actually getting anywhere at Mach 25+. Space sciences development has been more than worth the investment spent in it so far (and I'm just talking about communications, sensory, etc. satellites, not spinoffs), and I'm pretty sure that will continue to be true, but the timescale and investment magnitude involved is too big for any one company to risk funding the basic research themselves.

    More regulations, judiciously applied, would have prevented this crisis.

    Which regulations? Give details.

    I'd personally be interested in regulation like "You can't offer to insure someone for $x or to borrow $x from them unless you keep y*$x on hand to pay them off if necessary. And yes, this applies to anything that will make you similarly financially liable to them, whether you call it 'banking' or 'savings and loan' or 'insurance' or a 'CDS' or a 'rose by another name'."

    Sell people a specific argument like that and you might get surprising agreement - I'll bet you can even get some of the "No! Regulation evil!" libertarian types to insist that y should be 1.0 unless the customer signs a contract stipulating otherwise.

    But the vague word "regulation" just tells people: "We need more economic decisions to be made by people who have no financial stake in making them correctly, and who just agreed to give hundreds of billions of your dollars to people who made them incorrectly." You can probably convince lots of people of that argument, too, as long as you phrase it more obscurely than I did. But you still won't be able to make it into a good idea.

    Every officer who looks vaguely like they're acting improperly gets terminated and criminally charged.

    Interesting theory. Does every officer who looks vaguely like they're acting improperly get evidence rendered inadmissible? No? Then you've got an interesting, clearly incorrect theory.

    The punishments are insufficient to deter,

    I'd prefer that the punishment be: "whatever a non-cop would get for the same crime". Breaking and entering, wiretapping, etc. are crimes. If our anti-wiretapping laws are sufficient to deter blackmailers, for instance, they ought to also be sufficient to deter jackboots. If they aren't, then that's a separate problem that needs to be fixed regardless.

    and every so often a cop takes a fall to get "that guy we just knew was dirty".

    Could be. And then we either end up with a crooked cop and a criminal getting punished (good and good) or a crooked cop getting punished while a clean suspect gets reparations (good and not good). Sounds like a win or a wash to me.

    Note that the cop doesn't have to know he or she is going to take the fall

    So your third theory is that the cops have the ability to frame each other for crimes but not to frame suspects? After all, if you can get someone to take the fall for something they didn't do, why wouldn't a crooked cop just do that to the suspect and cut out the middleman?

    I apologize for interrupting the false dilemma here, but would it be a reasonable option to prosecute both the criminal who was caught and the cop who violated the Constitution to catch him? I know, I know, we've got two guilty people on our hands, and our natural, rational instinct is "let them both go unpunished, then set fire to our own hair"... but perhaps there's a way to disincentivize police excesses without giving criminals a get-out-of-jail-free card.

    I suppose there's an argument that anyone who would violate the Fourth Amendment can't be trusted as part of a chain of evidence... but in that case, shouldn't the guilty cop be kicked off the force entirely, not just distrusted regarding a single case?

    Those are just thoughts in general, though, not necessarily a recommendation for this particular case. Even if it was admissible, I'm not sure I'd want to prosecute someone with evidence like "Look at what we found on his computer, thanks to the help of some guys who felt cheated by him, took his computer, reported incriminating files to us, and totally pinky swear that neither of them put them there themselves."

Securing an electronic ballot box requires that you send someone who you can trust to watch the voltage on every transistor. Only the former can be accomplished by human eyes.
