    It's not exactly an efficient sink, is it? Your only option for heat transfer "outside" is infrared radiation, since vacuum does not exactly support conduction/convection.

    If you really want liquid-He temps, then you can't really radiate heat to lose it. At 1 atm it is almost as cold as the cosmic microwave background, and probably colder than the inner solar system. If they're running below 1atm then it is probably colder than the microwave background itself. This means that your radiator will only serve to warm up the spacecraft, not cool it off.

    For an IT analogy - how large a heat sink do you need to cool your PC in an oven? The only way to cool under such conditions is using active technologies, like phase change, or maybe Peltier. Since you're fighting entropy, this will ultimately require some source of energy, which will always be depleted eventually in a closed system.

    Astutely observed, sir, but I would add that all of that makes a compelling case for a public utility model, wherein one (quasi-governmental) entity owns the pipe (fiber, whatever) and sells access to it on an even playing field.

    That has always been my idea. For these last-mile problems have a public utility own the last mile, and ONLY the last mile.

    So, either the government or some highly regulated utility owns the fiber to the home, up to the termination point in the central office. They then charge customers to use those lines, and they charge service providers for rack space. Service providers can then engage with consumers to provide them internet service, cable, or whatever. For non-shared lines like twisted pairs and fiber the utility just charges a flat monthly maintenance fee that covers their costs to fix lines/etc. For shared lines like typical cable-based networking they would charge by the byte and rate period, just like electricity. Service providers could charge whatever they want as long as they're up-front about it, and competition would control things there. Since the last mile is a solved problem, there would be quite a bit of competition - in order to provide internet service all you need is a router, a service contract with your upstream pipe, and a monthly fee for rack space in the central office (at cost).

    MySQL (or MariaDB, or SkySQL) are not suitable for use in banking, but the vast majority of database applications don't have the same requirements of banks. Banks have extremely high data integrity, retention and security requirements.

    Most people who don't think they don't have all those requirements simply haven't thought of what could happen in the absence of those requirements. It isn't unlike every time I see a poster asking for collections to help out victims of some apartment fire - apartment insurance is fairly cheap and yet many people don't even think about it, despite shelling out almost as much for cable TV as insurance would cost them for a year. People just don't think they need insurance until they do, and then it is too late.

    Think about some database that has been collecting data for years. Now imagine that somebody does some data extraction from it and notices that some of the data looks inconsistent. You investigate and it turns out that under heavy load some records weren't getting stored by your database, or when some application error happens rarely that data is left in an inconsistent intermediate state. This has been happening for years undetected. Presumably if you're storing data for years it has some value, and now that value has been reduced. You might spend hundreds of hours coming up with ways to detect the problematic data and cleaning it up. Now, consider that if you had simply used an ACID-compliant FOSS RDBMS the problem would not have happened at all. Then when you investigate you find that using that database wouldn't have cost you anything more - the programmers simply used what they were more familiar with.

    I'm sure there are cases where performance is more important than data integrity, but the latter should always be considered the priority as a default. Most people just expect computer systems to regurgitate the data that is input into them without error, and they don't think through the consequences of what could go wrong if this doesn't happen.

    Right now I'm frustrated by the lack of Postgres support by FOSS projects. It is really annoying to be stuck with MySQL simply because the average college-age FOSS contributor doesn't understand the value of a database. The whole world runs on databases, and the typical CS program doesn't even talk about them. Sure, I grok the difference between CS and software engineering, but at least a theoretical treatment of the problems that databases solve would imbue graduates with a MUCH better appreciation for their importance.

    Who said anything about subsidizing them? If you are asserting that fuel taxes taken in by the US Treasury are less than the cost of ATC, prove it. My assertion is that fuel taxes already cover the operations of the necessary functions of the FAA which are specific to the plane operations, and the remainder of the money spent by the FAA is for net-goods that are consumed by everyone, including people on the ground, so there is no reason why the general tax funds should not be used in addition to the existing fuel taxes.

    I'm saying that fuel taxes should be set at a level sufficient to pay for ATC. If they are, then great - and it makes no sense to shut down ATC services as a result. If they aren't then they should be raised. I do not know what the current rates are, but the fact that they were affected by the sequester tends to suggest they aren't self-funding. But, it could just be political games.

    On the other hand, if the aviation community were to agree to increase fuel taxes, then the fuel tax revenues should be locked off from the general fund, or else we end up just like the Social Security "Trust Fund" - getting raided to pay for studies of monkey erections, piss-christ "art" and bridges to no-where.

    Nobody is going to ask the aviation community to agree to anything. The cost of FAA services should be recovered in fuel taxes, and the aviation community has the choice to buy fuel or not. Nobody asks me whether I want to pay income taxes...

    As far as the social security trust fund goes - just what do you think should be done with it? Should we have a big room full of dollar bills somewhere waiting to catch on fire? Should we be borrowing money and paying interest on it when we have money just sitting around? How many wealthy people take out loans while sitting on piles of cash (neglecting perverse incentives like tax loopholes and the like)? If you have a surplus in one area of the budget it only makes sense to use it to plug a hole in another area of the budget.

    Besides - having all that money saved up in a room won't do a thing for the baby boomers when they all start collecting. If the economy is so upside-down that the government would actually be unable to pay their monthly social security checks then those checks would be worthless anyway as the demand for workers increases wages and the costs of living to the point where you wouldn't be able to live on your promised savings anyway. The only thing that makes social security work is a lot more people paying in than collecting - you can't save money for retirement on a national scale, because money has no inherent value. The people who are working are providing the services, and the only way to provide those services to people who aren't working is to tax them. Money that is stored away which later re-enters the economy on a large scale just devalues itself.

    I am a pilot and I *do pay tax* every time I buy gas. We are ALREADY DOING THIS. Every time the "charge per flight, charge to take off, charge to land, charge to get a weather briefing, charge per mile, etc etc" crowd gets worked up, we (collectively through our GA lobby) point out just raising the gas tax is vastly more efficient and won't require an entirely new bunch of employees that will ALSO need to be paid out of these fees.

    I know that fuel is already taxed. Raising that tax is exactly what I'm proposing - take the annual budget for all FAA services, divide it by the number of gallons of fuel sold for use in planes, and add that as a tax to fuel.

    The only change vs the current state is charging more per pound of fuel. As you've pointed out it also avoids any perverse incentives to go flying into clouds without filing IFR.

    I'm not sure that any of this would ruin general aviation. Just charge a fuel tax. Jets burn tens of thousands of pounds of fuel, and they're 95% of the air traffic that consumes a lot of ATC services, so the tax per pound of fuel would be scaled for that kind of consumption. If you're just buzzing around VFR in your Cherokee I doubt that this will have much impact on your costs, certainly not compared to maintenance/etc.

    Unless you're a pilot and happen to own a plane and don't count in the cost of that plane, flying from small town to small town is already prohibitively expensive. Most people have to get themselves to at least a minor city to catch a flight, and it won't be direct unless one of the endpoints is a major city or the route is really popular.

    Please provide the math to back this assertion up. I'll provide three counter examples.

    You basically already provided the "math" - they aren't counter-examples at all.

    Currently all aviation users who purchase aviation fuels pay fuel taxes per-gallon, more flights = more gallons = more tax money. Strike one....So you want to tax aviation more than it already is? Remember the old rule, subsidize what you want more of, tax what you want less. Strike two.

    I realize that aviation fuel is taxed. I do advocate that these taxes be increased so that the necessary regulatory oversight can be self-funding. I fully agree that this is likely to result in less planes in the air.

    What's the problem with that? Why do we need to subsidize people flying around?

    Many nations other than the US have "fee based ATC". The only way to collect these fees is to structure your entire aviation system, from airport to navigation, to pilot training, to aircraft registration around fee collection. Note, all such nations have seen a dramatic DECREASE in the number of airports, and the number of users of these systems, even commercial operators use less of the ATC system by flying larger planes less frequently in order to maximize the number of flight-miles per ATC fee. Strike three.

    That is exactly how the US should operate. Again, what is wrong with having larger planes less frequently? We need empty planes flying around overhead about as much as we need empty trains driving across the country or empty busses driving around the city.

    Also note - that last item is actually the reason many nations in the world sends a large number of students to the US for primary and secondary flight training - we have the most options for them to train, and the best instructors - because they are busy enough to learn the fundamentals well and get to practice them. Fee based nations experience a drought of trained pilots to enter their commercial airlines,

    Great, so the US is subsidizing flight training for the world's pilots. Not sure how that helps the average US citizen.

    and even the US with the most open and inviting aviation system is seeing a strain with the already high cost of flying increasing beyond the means of the average citizen...Adding more taxes and more fees will only serve to further distance aviation from access to the average American as it has done to the UK and much of europe....Your inconvenience right now due to sequester is NOT a good reason to disenfranchise an ever growing portion of the population the right to affordable transportation, whatever the means.

    If you want to help poor people just give them a decent income and they'll be able to afford tickets, assuming they have anywhere to go. Using taxes to make it easier to fly a single-passenger flight to catch a football game 100 miles away isn't the most effective use of resources. I doubt the average poor person is going to be able to afford a Piper Cherokee, either - certainly not for less than the cost of an airline ticket. Just properly maintaining an aircraft will likely cost you at least a few tickets a year if you're doing half the work yourself.

From time to time I spend hours flying around in simulators and have entertained trying to build a half-decent one.
