    The tones at the end of Sgt. Pepper's are at 15 kHz - within the range of hearing of many humans, and certainly within the range of CD frequency response.

    That's not true. Ardour may not be DP4, but it certainly is acceptable for certain recording situations. Less-than-optimal, yes. Certainly. Less-than-user-friendly, yeah. Undoubtedly. And, as you said, it is showing a lot of promise. But utterly unacceptable? No. I've used it and a whole slew of LADSPA plugins to do some nice remixes of material I recorded for a personal album about 10 years ago. Sounds fine, works well enough. I gotta tell you, it's amazing how many tracks and plugins you can get operating on an Athlon 64 without even approaching cpu overload. And for me, in my situation, Ardour is much more useful than GarageBand, even if GarageBand is easier to use.

    I'm not disagreeing with your basic premise that Linux music production has a long way to go. I'm simply disagreeing with your statement that all Linux audio software is utterly unacceptable for any type of music recording, and I base that on my experience. YMMV.

  6. Re:Direction on Debris is Shuttle's Biggest Threat · · Score: 1

    Yeah, that's what I thought too. But think of this: suppose that you have a shuttle in an exactly perfectly equatorial orbit - meaning that the path is directly above the earth's equator at all times.

    Now imagine that some lump of debris got ejected from some orbiting object in that path, but had a sideways vector. Eventually, that object will be in an orbit which is at the same altitude, the same speed, but which is tilted relative to the equatorial; sometimes it's north of the equator, sometimes it's south. It'll intersect that equatorial orbit at two points. If you happen to be at that intersection point and time, you get smacked. The velocity of the smack is proportional to the sine of the angle between the orbits, and maxes out at the orbital velocity if the lump of debris is in an orbit which passes over the North and South poles. That's a lot of velocity.

    This is a simple example, and the actual orbits get much more complicated. Suffice it to say that your first approximation is correct as far as it goes, but woefully incomplete when the overall picture is considered. Like I said, I made the same mistake. That's why I'm an EE, not an orbital mechanic.

    Well, then, Anonymous Brave Guy, allow me to rebut a few specific points. Apologies if I have misconstrued or misquoted any.

    1) People who enforce laws shouldn't be required to have all of them memorized.

    Well, I'm going to agree that the average street cop doesn't need to know tax law. But I assert that someone who enforces one very small specific subset of laws, e.g. TSA law enforcement, should in fact have a VERY thorough understanding of what is and is not illegal within the purview of those laws. That IS their job. Otherwise, that person may enforce personal preference or prejudice rather than the laws, or allow illegal activity to continue and thus endanger the lives of passengers. I'll go further and suggest that there should be on duty at all times some TSA enforcement person who has a written copy of such laws available for public perusal and for agent reference. This is my opinion, of course, not fact. I'd like to go on record as vigorously disagreeing with both your opinion and the factual basis underlying it.

    2. Common sense suggests that a law requiring ID to board a commercial airliner exists and is reasonable.

    Common sense is neither.

    More specifically, I would assert that common sense suggests that if there is a law requiring you to show said ID, it can be found without having to break it first. That wasn't the case. The author might have tried to find such a law (the fine article doesn't say), perhaps in reaction to a previous TSA enforcer's actions*, or out of a desire not to have to tell every random stranger in a uniform that he was an epileptic, and couldn't.
    (*Having flown several times in the last year, I can relate from experience that TSA people can often be rude, unpleasant, and leave one with a sense that one's privacy and dignity has been invaded unnecessarily. )
    Common sense suggests that if one searches diligently to find a law prohibiting or requiring some pattern of behavior, and can't, then that law doesn't exist. That wasn't the case.

    3. Making the scene that he did was unnecessary.

    How else do you find out about secret laws, other than breaking them? Clearly we can't trust our lawmakers to be open about what's illegal. Applying common sense, as we've seen above, won't do either.

    As mentioned previously, he may have had perfectly legitimate reasons for not wanting to show his papers - excuse me, for not wanting to show or have a TSA-approved photo ID.

    Turning this around, common sense suggests that hiring a lawyer to file a court case to ask the government whether a specific law exists is unnecessary. However, this is what you said was "the correct answer." I'm thinking that perhaps common sense means something else when you say it. Maybe that's why we have laws instead of asking everyone to rely on their common sense...?

    4. The TSA enforcement people reacted appropriately to this incident, as they would to a threat against the President.

    I didn't really understand this - I'm hoping this was you being unclear in your phrasing, rather than as simple-minded as it appeared. Joking about assassinating the President is not a particularly parallel case. It's explicitly illegal, a Federal crime, and the law is readily available for citizens to read. Moreover, the foreigner who jokingly makes such a threat will quickly meet some nice Treasury Agents, probably members of the Secret Service, each of whom is perfectly capable of telling him exactly which laws he has broken. They will be polite, knowledgeable, and very serious.

    TSA agents pulling a man out of line without being able to cite the relevant law is not reasonable or appropriate. This is NOT a personal fiefdom for agents to throw around personal power; this is a sensitive position in which agents are tasked with enforcing laws to protect "transportation"**. The agent's responses, FTFA, suggested that he pulled Gilmour at least in part because he

    The no load loss in the transformer is probably due mostly to hysteresis loss in the core, and so you're probably right - that loss is probably much greater at idle. Might even be the same total power loss as in the full power case, which is about a half watt. I'd still like to see measurements with an actual power meter.

    Thanks for pointing that out.

    DC wiring? Voltage dividers at each location? Are you nuts?

    This is poor advice.

    1) Well-designed wall warts are not that inefficient. Some geek with an ammeter who doesn't know the difference between real power and complex power may suggest otherwise, but he's wrong.

    2) Resistive voltage dividers are either a) mind-bogglingly poor regulators or b) mind-boggingly inefficient or c) both. Add in the fact that the resistors tend to get HOT, and you're got a recipe for unhappiness.

    3) Linear regulators, such as the venerable 7805, provide good regulation but the efficiency drops as the input voltage rises. Delivering 1 watt of power from a 5-volt regulator connected to a 24-volt supply is only 21% efficient - it wastes 4 watts to deliver 1! It also uses about 1/4 watt at idle (no load).

    4) AC transformers can easily be greater than 90% efficient. Choosing a secondary and rectifier to give you a 7.2 volt unregulated supply and then regulating it down to 5 V with a 7805 will deliver 5 watts with about 52% efficiency, and will draw around 65 mW with no load - far less than the 1-5 watts you've claimed. I'm curious to know exactly what sort of wall-wart is being described there.

    5) That 65 mW I calculated will cost (around here) far less than $1 per year. There are 8,760 hours in a year, which is 8.76 kilohours. A constant drain of 1 watt will result in an annual energy use of 8.76 kWh. Electricity at $0.114/kWh would result in an annual cost of exactly $1 for a constant ** 1 watt ** drain. You'd have to have a LOT of really inefficient wall-warts to justify running a complete secondary DC supply system, even if its efficiency were as good as you think it would be.

    6) Switching-supply wall warts can be much more efficient than linear regulators, and run cooler. 80%-90% under full load is common, although quiescent efficiency can be much less.

    In summary, anyone who suggests using high voltage DC and dividers to increase efficiency clearly knows nothing about power conversion OR efficiency. If you REALLY want to save power used by wall warts, don't listen to parent. Use switching-based wall warts and disconnect them when not using them. If you are really worried about saving $1/year, running a (thousand dollar or more) auxiliary power system is penny wise and pound foolish.

    So what defines a good interface? Easy to learn? More familiar to users of other packages? Faster and more powerful once it has been learned?

    I submit, sir, that the latter is a perfectly valid definition of a good interface, and that Blender succeeds in that area admirably. There are, as others have stated, some tasks that simply require a level of complexity in the user interface which inhibits ease of learning. Blender allows the experienced user to perform tasks very quickly and comfortably, despite their extreme complexity.
