    If it isn't about doing your work, then why do you do it?

    I thought what I meant was clear. I never intended to claim that VC was useless, non-productive, or non-work. In fact, part of my point was that it is work, which many people don't understand. By "not doing your work" I meant simply that your final product is a program, not a tree of revisions. Time spent on VC does not directly result in satisfying customer needs, rather it makes it easier to create reliable software more quickly, and with less risk of losing information you need.

    Of course VC is an incredibly useful tool, essentially required in many applications. I use it all the time, and almost every time I think something is not worth adding to VC, I regret it.

    Unfortunately, for drawings I usually use Illustrator or Canvas on Windows. I also generate figures in Matlab, which can be automated, but is a major pain to do so. Ideally, I would switch to Inkscape for the drwaing, but last time I looked at it (quite some time ago) it was not ready. I hear it is much better now, but I am not going to learn a new program halfway through writing my thesis.

    You are not alone, but I think the problem is intrinsic (or nearly so). VC is one more thing you have to worry about that is not actually doing your work. It is easy as long as you don't want to do anything with VC you couldn't do otherwise. If all you do is linear development of a single branch, it is pretty easy. Memorize a few commands for import, checkout, and checkin and you are fine, but all you really get is a backup system. As soon as you want to branch and merge and so forth, it becomes much more complicated.

    I think the only way to make it work really well is to have an administrator whose job it is to be a VC expert, rather than a programming expert. You need someone with some serious scripting skills and a deep understanding of the structure of the VC filesystem. With the proper scripts in place, you can really streamline the process for your specific project and enforce your coding practices, but maintaining the system is a seperate skill from programming. Also, when performing non-standard merges or whatever, you would probably need a coder to work with the admin to make sure you don't do it in a way that will hamstring you later. Of course, most projects can't afford that, and many programmers don't want to leave their code in the hands of some script monkey, or won't believe that someone else can do something as "trivial" as vc better than them :)

    I use subversion to track latex documents, which have figures in them. I usually store both the original source file (often a binary) as well as the .eps version of figures (text, but might as well be binary) in svn, since I can't regenerate them from a script.

    I don't understand why the author of the article wants to do what he is, but lots of people have good (or good enough) reasons for wanting to track binary files.

    I always hope I don't have to keep binaries in svn, but since so many people seem to love them (for reasons passing understanding) I often end up with binary files under VC. Not sure why I would want it to track deltas... most binary files I can think of would not be likley to generate large common regions between versions, but I am sure it could be useful for someone.

    While the republicans are currently much more apt to dismiss science that would force them to reevaluate their political positions, there is no party bias in appointing unqualified individuals to scientific posts. For instance, the secretary of energy has a long history of being filled by people with no expertise whatsoever, regardless of the party in the whitehouse. This is because those posts are not visible to the public, and few people even in congress care how well they do, so they are often given out as rewards or favors, with the only consideration being that they are not somehow politically inflamatory enough to fail confirmation.

    I would say that my mixed-sex high school and college had a much better social atmosphere than my mixes-sex junior high. I am not sure there isn't a case to be made for same sex schooling in some cases, but I strongly doubt that overall it is a good idea at the college level at least. If people can't learn to focus on their work when it is important and there are girls (or boys) around, they are going to be useless in the outside world.

    Also, the argument for allowing women-only schools and not men only schools is based on some legitimate concerns (though I still think it is a bad idea). One is that males tend to be more agressive, and can monopolize the time and resources of the instructors, or indirectly intimidate women into not engaging the class. To the extent this is true, it is probably an issue best addressed by the instructors, not a segregation policy. Another is that historically, many mens schools were considered more presitgious, and students from those would be preferentially hired, or admitted to college, which has been an additional motivator to desegregate those schools. In the final analysis, a lot of women wanted and worked for the opportunity to go to schools that had been male only, while the reverse is not true, so women's schools have desgregated slower.

    One reason is that wall warts come in regulated and unregulated varieties. An unregulated 5V supply is typically designed to be able to run a 5V regulator over the standard range of wall socket voltages, meaning it can have a no-load voltage of 8-9V. A regulated wall wart will have a 5.0 output voltage with nearly identical labeling.

    The difference is that if you succeed in hitting someone with the knife or gun, you have commited an actual crime. If you succeed in having sex with an FBI agent posing as a 15 year old girl, you have not commited a crime. Sex with a minor is one of only a few cases where intent to commit a crime is sufficient even if the act attempted is not actually a crime. Stabbing a dead body is not murder, breaking into your own house is not B&E, and stealing something being given away for free is not theft, even if you don't realize what you are doing is legal. Likewise, believing your actions are legal does not establish your innocence. Having sex with a minor who claims to be 18 is still illegal, and will land you in jail, though in some cases the crime may be different.

    The 2nd Amendment in the US Constitution is not there to protect the rights of deer hunters.

    Agreed. And I never even implied it was. The discussion was on whether categories of firearms are sufficiently different that we might make a legal distinction in how they are treated. The answer to that question is unequivocally yes. Whether we need or want to make those distinctions is up for debate. My feeling is we should.

    Incidentally, in my opinion, the discussion about whether or not the populace should be armed or not was resolved to my satisfaction more than 200 years ago, and it's been downhill since then.

    Luckily nothing has changed in 200 years.

    People going on shooting rampages is terrible, but a statistically insignificant effect. However gun crime on the whole is absolutely relevent to the discussion of whether and how the populace should be armed. It is not the whole story, but if you insist it is not part of the story, you are a moron. Self defense is another important issue, and protection from tyrannical regimes is a factor, if somewhat theoretical in modern America. Protection from invaiding forces, as in a well regulated militia, is a nice idea, though I think we have that covered pretty well. The practicality of trying to get guns away from would-be criminals rather than merely taking them from honest civillians is another thing we have to deal with. Gun safety and training. The list goes on.

    So, by your argument, we should be regulating deer rifles, not "assault weapons", because deer rifles are more deadly.

    I don't know. Maybe. As I said, regulation is a complicated issue that has to take into account many factors. If I thought I knew what the answer was, I would have said so.

    One can change an assault weapon into a perfectly legal one by changing the furniture on the weapon.

    That is indeed silly. The fact that the legal definition of an assult weapon as decided on by a forced compromise between the "OMG GUNS R EVIL" camp and the "I need a chain gun to protect my family" people is bogus does not surprise me, or make me think that a rational approach to gun legislation is technically impossible, only politically impractical.

    Again: The most dangerous component of a firearm is the person wielding it.


    This is true, but like most attempts to sum up a complex issue in a single aphorism is largely meaningless. It is also true that guns allow an untrained person to inflict more damage in a shorter amount of time with less effort than any other easily available tool. Neither statement is particularly useful beyond a slogan to stir up sentiments of people who already agree with you.

    The design considerations for a gun to be used in hunting, military action, and law enforcement are all considerably different. It isn't so much a difference in the target (medium sized mammals are all the same), but the goal, the environment, and the acceptable side effects.

    For instance, the AK47 and M16 would make poor deer hunting weapons because they have low stopping power (your deer is likely to run off out of sight before dying) in burst fire mode, multiple hits are likely, which is bad if you actually want the meat or hide, as well as making it somewhat more dangerous to fellow hunters.

    Regardless of the technical definition of an assault weapon, the guns most often labeled as such were clearly designed for attacking groups of human targets. It isn't always cut and dry, since as you say the round makes a considerable difference in the performance of a weapons. That doesn't mean there is no distinction.

    Whether or how to regulate weapons of all types is a much more complicated question, but to argue that there is no distinction between handguns, hunting rifles, and assault weapons is simply ignoring the truth.

    384k is not a dent in their operations, but if they have woefully underprovisioned their total upstream bandwidth it doesn't take too many people pegging their upload speeds to degrade performance for everyone else. That makes angry customers, and the cheapest solution is to eliminate the 1% of their customers that cause problems.

    I understand nobody buys hosting from the cable company, but since large links are always symmetric I assume the bandwidth has to go somewhere. With DSL it is easier to see, since the phone company sells large symmetric links to hosting companies and so forth who underuse the downstream bandwidth which they can effectively double-sell to residental DSL customers cheap. Presumably something similar happens with cable companies--they have to get their bandwidth from someone.

    One advantage of fiat money (I am not saying there aren't disadvantages) is that if suppliers of a few commodoties agree it has value, it essentially becomes backed by all of them. With a standard based on rare metals, you are subject to market collapse on discovery of large amounts of the ore. This happened somewhat with silver. Had aluminum ever been used as a monetary standard, it would have collapsed when electrolytic process for reducing aluminum ore was found.
