    If you pay for the photograph, it's a work for hire that belongs to you, absent a contract saying something different.

    In the US, that is false. See wikipedia for details; essentially there are several criteria that must be satisfied for work by an independent contractor to be work for hire, including in particular that there must be a written agreement between the parties stating that the work is made for hire.

    I'd really rather if they not do that. If it becomes standard to link to the print version of articles, sites will just remove the print option entirely. As it is, we, who care, get to enjoy these articles in a relatively clean form for minimal work, and the people who don't care effectively subsidise us (thanks!) with their ad impressions.

    The MOVE bombing wasn't even remotely similar. Firstly because it was a row house, i.e. physically connected to the adjacent buildings, secondly because the firefighters at that site did nothing to control the resulting fire, and thirdly because the area was not evacuated prior to the bombing. This is a ranch house, so the fire is unlikely to spread, firefighters are on site to control the resulting fire, and the area will be evacuated.

    There is a fascinating account of building a radio in a Japanese POW camp during WWII virtually from scratch.

    So we hit upon the idea of taking some tin foil or aluminum foil from the lining of the tea chest from which the Japanese supplied with the rice rations, then by the well known equations for calculating capacity and the relationship of the surface area and spacing of the plates, we built a capacitor or, at least, I built a capacitor which according to calculations should have been about ".01 microfarad."

  6. Re:This is second place on Proving 0.999... Is Equal To 1 · · Score: 2, Insightful

    You are confusing a symbolic representation for a number because the symbol contains numbers in it. It is physically impossible to represent certain numbers using base 10. Pi for example. Is is less obvious, but still a fact that 1/3 and 1/9 are in fact impossible to accurately represent using base 10. The .1111... .33333... and .9999... are all of rather limited accuracy symbols, not numbers, just as if I were to say pi = 3.14159+ The 3.14159+ is a symbol representing Pi, not a number, similarly .9999999... is NOT a number, but is instead a symbolic representation of a number.

    .1111... is understood to stand for the supremum of the set {0,1/10,11/100,111/1000...}. See Rudin, "Principles of Mathematical Analysis", page 11. Likewise for .3333..., .999999...., and 3.14159+... where the sets are defined accordingly.

    The fact that long division or electronic calculators come up with those results is an indication of human accounting for the limitations of our mathematical symptoms.

    Calculators produce such results because they are useful approximations of the supremum.

    In base 8, .11111111 = 1/8 + 1/80 + 1/800 + .... That number, multiplied by 7 becomes .77777777777... or 7/8 + 7/80 + 7/800 +... You can use the same bad math you used earlier to prove that 1 = .7777777... base 8 that you used to claim that 1 = .99999 in base 10

    Here you are in error. 7*.111111...= 7*(1/8+1/8^2+1/8^3+...) = 7/8 + 7/8^2 + 7/8^3 + ... = (7/8)/(1-1/8) = 1; the reduction from an infinite geometric series to 7/8/(1-1/8) is a common result from any high-school algebra course.

    Note in particular that 7/8+7/80+7/800+... is not equal to 1.

  8. Misleading summary on Designing Wireless Sensors To Be Dropped Into Volcanoes · · Score: 4, Informative

    According to Horsfall and his fellow nails-tough tech developers, their carbide electronics can keep working up to temperatures of 900C. This is actually sufficient to withstand immersion in some lavas/magmas, though by no means all. In any case it's difficult to see how any wireless signal could be transmitted through molten minerals, so presumably the inventors are talking more about locating their kit in places within a caldera which - although extremely hot - are not enough so to actually melt rock.

    The caldera is not a synonym for lava puddles. They're talking about putting a sensor in the caldera where it can detect gasses. It's not likely to be floating, much less submerged, and in fact that would presumably interfere with the mission of detecting various gasses.

  12. Not necessarily forced on IBM's Patent-Pending Traffic Lights Stop Car Engines · · Score: 2, Informative

    Upon receiving the stop-engine notification, the vehicles may automatically switch off the engine, or display an alert informing drivers to manually switch off the engines. A vehicle may optionally notify the service once its engine is switched off.

    For all of you concerned about not having complete control.

    The summary doesn't effectively explain when this would be useful. At most lights, it won't matter. The example the patent gives is a 2 minute light, for which it is inefficient to restart the engine state. It suggests "waiting for 10 minutes for a railway to clear" as a case where this would be useful.

    The patent seems very vague. It talks about processing information about the movement about other cars, doesn't comment on what should be looked for, how that information is to be determined, or how wait-time should be estimated. It basically seems to be a patent for the idea of signaling the car when a long wait is anticipated.

  14. Cargo pants are nice. on How Do You Handle Your Keys? · · Score: 1

    Do you really need all those keys on you? It seems to me that the *three* keys for your girlfriend's place are probably somewhat redundant. Maybe they're front/back/basement keys, in which case you probably need only one unless you're living there. Your roof key can probably be stashed at home.

    Cargo pants are really nice, if you can wear them. In general, keyfobs aren't worth the hassle. If you need what they have--the SAK, for instance--take them off the keychain and carry them either in your pack, which you apparently have with you most of the time, or in some other pocket. Though the later doesn't reduce the total volume of hardware, it does spread it out, and is thus much more comfortable.

  15. Re:Don't they already have jobs? on Astronaut Careers May Stall Without the Shuttle · · Score: 5, Informative

    I thought so too, so I looked into it. Apparently this was the case in the early days of the program, and is still mostly the case for pilot astronauts. "At least 1,000 hours pilot-in-command time in jet aircraft. Flight test experience is highly desirable." [1] (In practice, they all seem to be test pilots). This is not a requirement for Mission Specialist Astronauts.

    I also suggest browsing some of the astronaut bios from the last couple batches. Of the last five pilot astronauts candidates, all five are former military test pilots. Among the twelve Mission Specialists selected during the same period, there is only one that I can confirm as a test pilot. At least four have a military background, and at least three were pilots before entering the program. At least two others were flight surgeons; this may well mean that they qualified as pilots

    Really, though, they're all very well qualified in their respective fields. They may lose their jobs, sure, but I doubt they'll have trouble finding others.

    recitation. By "recitation" he meant, "speaking the English language." He did "not mean giving back, verbatim, the words of the teacher or the textbook." The children would be asked to talk about topics that interested them--experiences they had had, movies they had seen, or anything that would lead to genuine, lively communication and discussion. This, he thought, would improve their abilities to reason and communicate logically. He also asked the teachers to give their pupils some practice in measuring and counting things, to assure that they would have some practical experience with numbers.

    Simply removing all math from the curriculum would very probably not produce the same results.

    Also because it kills the argument that this DRM isn't a big deal for anyone who doesn't plan to play the game for years. I know I've been told (by Battlefront.com, when inquiring about their system) that I was more likely to stop playing after years due to compatibility issues than because their DRM servers closed. Ubisoft presumably would have said similar, if asked about the end-of-life of their servers.

    I was impressed by that as well.

    Wikipedia claims

    The neurological autonomy of the arms means that the octopus has great difficulty learning about the detailed effects of its motions. The brain may issue a high-level command to the arms, but the nerve cords in the arms execute the details. There is no neurological path for the brain to receive feedback about just how its command was executed by the arms; the only way it knows just what motions were made is by observing the arms visually.

    I'm curious to see if their ability to walk will challenge that assertion. Maybe it just makes their ability to walk all the more impressive.

    IANAL, but I don't think it applies because Freenet isn't a "a program, application, or software that is commercially marketed or distributed to the public."

    Furthermore, my understanding is that Freenet stores the shared files in a single, encrypted file. Shared files are not stored within the host filesystem, correct? Then it need only notify the user that the encrypted file it uses will be shared, without necessarily notifying the user of the contents. Uploads to Freenet are accomplished with independent software that requires initiation by the user, and is therefore not covered by this law.
