    I think it's a bad plan to get assassinated right after being elected, since you don't take office for a while yet. Also, people usually don't get buried for three days after dying. Oh, and you can't get elected on a Friday; people vote on a Tuesday and the electors cast electoral votes on a Monday. If you win the 2016 election, however, you can get inaugurated on a Friday, which will have to do.

    (IANAL) If the license on the code that they paid you to modify requires that changes be licensed under the same license, then they own the copyrights but they'd have a hard time arguing that you don't have a license to it. (So far as the changes are a derived work of the code they don't own; separate stuff that you did along with the open source project doesn't count.) Just make sure that the copyright notices credit the company (not yourself) and that the license is GPL-like rather than BSD-like. (If they pay you to work on a BSD/X/MIT-licensed piece of OSS for internal use, they may well be preparing a proprietary version, which is perfectly fine by the license, and you don't get to pass it on.)

    Note that the important detail here is that the company is under license obligations in order to prepare derived works of the code they don't own and use those modified versions.

All of the programs I used in '98 are still maintained in '08, with the occasional name change and slight changes to appearance and behavior, except for netscape. All of these programs were open source, except for netscape. I hear that Windows 95 and Office 97 haven't gotten any updates lately.

  4. Re:Any real effect? on Coverity Reports Open Source Security Making Great Strides · · Score: 2, Informative

    Most of the flaws that Coverity finds are not bugs in the sense of cases where the code does the wrong thing. They are more often areas where the code works as written, but is misleading in some way, such that people working on the code are likely to introduce crashes.

    A lot of other flaws they find are cases in which the program crashes cleanly (by dereferencing NULL) in some error case instead of reporting the error. Depending on what sort of program it is and what sort of data error is required to reach that point, it may not matter (e.g., if there's some weird thing the user can do that crashes their mail client, it's not a big deal, because anyone who could do that could also just tell it to quit). But, again, reasonable changes to the code could expose this as a real problem, and having these flaws means that the description of the state of the program that the programmer has to keep in mind in order to only make correct changes is more complicated, and the intended behavior of the program is harder to pick out from the actual code.

    And then, of course, there are real issues that they're finding, and these are often difficult to distinguish automatically from things that are just badly written, and it's better to just fix everything that's wrong rather than trying to determine how wrong it is.

    That system is essentially what the ACLU is complaining about: if a ballot is unclear, there's no way to allow the voter to try again. The advantage of optical scan machines in the polling places is that they reject unclear ballots when the voter tries to cast them, so the voter can cast a replacement. The physical ballots, after they're scanned and accepted, go into a box and can be recounted by humans if necessary.

    This is a great example of science journalism. The study that the article is based on found that Wii games use at least 65.1 kJ/kg/min more than the 125.5 kJ/kg/min burnt playing sedentary games. Because science journalists lack even rudimentary math skills, they're often unaware that "2% more" isn't the same thing as "more than half again". Furthermore, since they also lack reading comprehension skills, they weren't tipped off that the position of the article was dead wrong by the statement that energy use when playing Wii games "was significantly greater than when playing sedentary games".

    Of course, they also failed to notice that the study was from an issue of BMJ consisting entirely of jokes, like every other Christmas edition of this journal. In case it wasn't sufficiently clear that the articles were all jokes, one of the articles analyzed the distribution of types of jokes in articles in BMJ Christmas editions. It's unclear whether the cited study was actually carried out (some people will go to great lengths for a joke, perhaps even so far as to play video games in lab), but that just makes it even more annoying that the article managed to come up with a conclusion entirely contrary to the only possible source.

  11. Re:Dictionary - Encyclopedia - Textbook on Should Wikipedia Allow Mathematical Proofs? · · Score: 1

    Textbooks and Encyclopedias differ in the relation of the text to the audience. A textbook is designed to teach a topic to an audience who has a particular background (from reading earlier parts of the textbook) and who needs to understand the topic in a way such that it can be applied to understanding later chapters. An encyclopedia presents self-contained articles, to be read in no particular order, with the reader generally starting at some topic of interest and reading that article as well as other articles needed to understand it, and it presents a wide variety of information about the topic (such as different historical ideas about the topic and who the people involved were).

    Due to the unordered character of an encyclopedia, having proofs is essentially worthless, because a proof will rely on a set of other theorems, which all must be proved first. But without an ordering of theorems, it is impractical for the reader to verify that the argument is not circular. And there are generally a number of different proofs of each theorem, each depending on different theorems being proven first, such that an arbitrary collection is almost certain to be circular, especially if the clearest proof available for each statement is used.

    So I would claim that it isn't right for a single document to attempt to be both an encyclopedia article and a textbook presentation. On the other hand, I think that Wikimedia should host sites to contain information which is of sufficient quality but of the wrong character for Wikipedia, and this sort of information should be cross-linked with Wikipedia. Wikipedia inherently has a particular organizing principle which is not appropriate for all valuable information, and other types of reference work should not be forced into an organizational structure that does not work for them.

    It's a lot more likely for individual consumers that their cars will store less electricity than their homes use, and they'll plug them into the house's electrical system, so that they do the same thing this article describes but on a purely personal scale: use the car's battery to allow them to get power from the grid at off-peak times, when it's cheaper, and store it until times when the power costs more.

    This is also beneficial in exactly the way the article suggests, since time-based price differences for consumers, if the consumers systems can respond to them, will help to load-balance things that can't be made as responsive. And if the area prices electricity such that individuals get credited the current price of electricity for power that the grid pulls from them, they can get credits on their power bills for storing it across price changes.

    I'm a bit dubious of the possibility of individuals getting money for just being available (rather than by playing the obvious commodities market), but it's entirely plausible to do it with corporate car fleets.

    As an end user, assuming you don't want Bernstein's own distribution of the source (if you do, taking public domain source directly is fine for your purposes), you're going to be selecting among redistributors, and you can do so based on the terms they impose, and you can simply reject any that don't give you the rights and abilities you want, in much the same way that you would reject proprietary programs not derived from Bernstein's work.

    (I am not a particle physicist or a mathematician of the right sort, but I can kind of follow this sort of thing)

    Okay, the context is that you've got particles, and they're fundamentally all the same, but they're "turned" in different ways. Think of a ball with 3-color LEDs inside: you can rotate it around three axes, and move it in three directions, and you can also cycle its color and change its blinking pattern. Particles are like that, except that the topology is weird: it's not back to the same orientation until you turn it around 720 degrees, instead of 360 like normal objects. The "gauge group" is the rules for how you can change things. For example, the total color of the universe is white: if you turn something from red to blue, you have to turn something else from blue to red; but you can also create a pair of a green and a purple (anti-green). They write all these rules up in math, and it's tricky because a lot of the features vary continuously (that is, you can rotate something an arbitrarily small amount). And due to the interaction of the rules for one property with the rules for other properties, there are only certain combinations of properties that you can get. They work out all the combinations that you can have and those are what you see as "different" particles that your experiments show. Of course, we don't know what the rules are, and we're trying to figure that out from what combinations of properties we've seen and which ones we're speculating are impossible. And it's hard and takes a lot of calculation to figure out what a candidate set of rules would even mean as far as results. And people are looking at known results and trying to describe them better than "we've done a billion things, and a billion things happened".

    Now, the math of rules for how things can interact turns out to be sort of limited; there are basically 4 normal cases, which are boring, and then there are a few exceptional cases, which are interesting. Of these, the hardest to prove stuff about is E8, and it's just now becoming clear what combinations it allows. It's like one of those puzzles where you press a corner and lights change, and you have to turn off all the lights, but it's got dozens of corners and dozens of lights and every time you press a corner a bunch of things change at once, and there are different kinds of corners and it also matters exactly what angle you're holding it at, so there are hundreds of things you can say about each move.

    And the mathematicians working on E8 recently said, "well, you can get positions like this and not like that", where "this" and "that" are big complicated lists. And this physicist read that paper and said, "hey, those lists are familiar; I made similar lists of particle interactions". So the proposal is that particles work like E8 in what kind of rules they follow. And it's a really nice theory, because E8 is essentially the most flexible set of rules you can have without it falling apart into just anything being possible (and some rules or properties just not mattering).

I think people who are either totally blind or quadrupelegic have to submit absentee ballots, and people who are partially blind probably need to bring their own magnifying glasses, but I don't think either is unreasonable.

    After marking your ballot, you put it in a privacy folder and feed it into a scantronic machine, which counts the votes as the ballots are collected, in addition to keeping all of the accepted ballots in a box that can be checked by hand in the event that the machine breaks or fails to agree with counts based on the lists of who was given a ballot and who turned one in.

    IIRC, the machine also rejects spoiled ballots (ones which it can't read clearly or which don't make sense), so the voter can try again. (I haven't messed any up, but I think I remember being there when somebody else did once) If the machine accepts a ballot, it's got to be perfectly clear.

    AFAICS, this is the ideal device: the ballots are marked physically and directly by the voter, an electronic device looks at each ballot to determine whether it is marked correctly, and the original ballots prepared by voters are available for inspection afterward. I haven't tried buying one, but I think they're easily available, and are also used for standardized testing and such (so there's a large body of other users concerned with scanning accuracy).
