    Again, read the damned article. It says being bumped into by one of these is like being bumped into by a person. And since they can be slowed down, they can move with pedestrians.

    So, why don't you go bump into someone who weighs 65 lbs above average at 17mph and tell us how it feels? Better yet, what if they're going 17mph in the opposite direction?

    At that speed you have a non-zero stopping distance, so you need to ride in a place where there are well-understood rules that reserve a right-of-way for a safe distance in front of you. This is the same reason that sensible cyclists ride in the road and behave like drivers of vehicles. People who don't understand this principle think they must avoid riding in traffic at all costs, and get themselves badly hurt crossing driveways on the sidewalk at bicycle speeds.

    Those massive speeding hunks of metal in the road make cyclists/scooter-riders/whatever *more safe* rather than less, because they enforce certain rules and habits that you need to ride safely at any useful speed.

    (Note, however, that despite the safety advantages of riding like a vehicle, it is also *not* illegal everywher to ride bikes on the sidewalk, as other posters have claimed, although some local governments do have laws that restrict riding on the sidewalk in some areas. Riding on the sidewalk is safe if you ride extremely slowly and treat every driveway and intersection as if it had a stop sign. When traffic is really bad, sometimes this is actually a useful alternative to have....)

    My street is 45mph, it only does 17mph. I only live 5 miles from work, but we dont have bike lanes or sidewalks for me to use it.

    I ride my bicycle on roads marked 45mph all the time, and I'm sure I average less than 17 mph! Safe, sensible cyclists have done so for years. It's legal and good for you. Just ride in the lane, obey all the traffic laws (don't ride against traffic, run red lights, hug the gutter, or make sudden left turns from the right side of the road), and you'll be fine. If you're also courteous about sharing the road---keep to the right of the lane when there's space for people to pass you, etc.---then you won't slow up any that 45mph traffic for more than a moment.

    Bike lanes and sidewalks can be dangerous for cyclists. You still interact with other vehicles constantly (at every driveway, intersection, etc.); the difference is that the interactions are more complex and unexpected--do you check for 15mph sidewalk bicycle traffic when you turn into your driveway?

    A high-efficiency, cheap, fun, non-polluting, fast, reasonably long-range car-alternative has been available for years--the only reason so many people don't realize it is that they were brought up to think of the bicycle as a toy good only for sidewalks and playgrounds. A bicycle is a real vehicle; treat as such, and you'll be much happier.

  5. Doesn't anyone have a clue what broadband is for? on Broadband Is Dead (Or At Least Very Ill) · · Score: 5, Insightful
    But wait, there's more! Not only is the broadband carriage business in trouble -- so is the broadband content business. There isn't a single company providing high-bandwidth content to mass consumers that is making any money on it.... When you watch a broadband video clip on abcnews.com or cnn.com, both companies are losing money to bring you that content. And the accountants have spoken: There is no way they'll ever make that money back. So companies that used to put a lot of money into high bandwidth content are putting in less and less money, so there is less and less content available. If you thought it was bad before, it will get worse.

    Cringley falls into the same trap as everyone else when talking about what broadband is used for. It's not about speed. Nobody cares about "multimedia", and the reason that the video clips on CNN's website will never attract customers is that none of their customers care about the stupid video clips, not even the broadband customers; I'll go to their website to read the articles, and I'll watch TV if I want video. (When the major news sites pared down their website to the bare essentials on September 11, did you miss all the fluff?)

    The reasons I have DSL are:

    • It allows me to log in to my home computer from work and while travelling.
    • It gives me the option of running various kinds of servers and persistent clients that give me more control over my web pages, my email, etc.
    • I can use google more easily for quick reference, since I don't need to wait to make the connection and don't need to worry about hogging the phone line.
    • I can download software, OS upgrades, etc. This dosn't require lots of Mbps, just a persistent connection--I can always let downloads run overnight.

    I wish broadband companies would stop trying to sell their service as some sort of expensive low-grade form of cable TV and instead figure out how to explain to customers the real advantages of a reliable, persistent internet connection. As first steps they could stop blocking ports and using dynamic IPs, and they could stop advertising high Mbps numbers, which nobody believes, and "streaming video", which nobody wants.

    AT&T Broadband does not allow servers to be connected to the cable modem. This means that no computer in a personal network can be used as a server.

    That seems pretty clear to me! Perhaps the leasing agreement isn't the only agreement you're subject to (I notice they also have links to an "acceptable use policy", but they seem not to be accessible by non-AT&T users). In any case, I wouldn't want to have to be in the position of having to argue the point with them after they'd blocked port 80. If you want to run servers, go elsewhere if you have the choice.

    The "detective noir" style that Jeter incorporates into "Noir" is traditionally laden with violent similes and metaphors.... <snip>....This is a style choice, not bad writing. Check out any Mickey Spillane novel and compare it to "Noir".

    I'm not familiar with Mickey Spillane. The author that came to my mind was Raymond Chandler, who also does this sort of thing. Compare an excerpt from Noir:

    He had turned from the window where he had stood waiting, turned upon the sense and smell of its arrival -- no sound, it walked so softly, silent as that other world -- and had seen the smear of blood on its brow, Cain-marked and Lilith-born, the great wisdom of indulgence in its idiot eyes. That had scanned and judged him, like the lenses of the watching security cameras at every corner of every building. First from across the room, as he had felt the first tremors of fear move out from his gut, then inches away, then less than that as it had stood right in front of him. The other's eyes had been round dark mirrors in which he had seen himself, perhaps more clearly than ever before.

    ...with an excerpt from Chandler's "The Long Goodbye":

    "I'm a licensed private investigator and have been for quite a while. I'm a lone wolf, unmarried, getting middle-aged and not rich. I've been in jail more than once and I don't do divorce business. I like liquor and women and chess and a few other things. The cops don't like me too well, but I know a couple I get along with. I'm a native son, born in Santa Rosa, both parents dead, no brothers or sisters, and when I get knocked off in a dark alley sometime, if it happens, as it could to anyone in my business, and to plenty of people in any business or no business at all these days, nobody will feel that the bottom has dropped out of his or her life."

    Both of them have digressions, but some side trips are worth more than others....

    That's what I would have though, too. But how about taking a look at the links section on his website and then taking a guess at which side of the issue he comes down on?

    It leaves you with a weird impression; on the one hand, you can't believe he's really serious about the scene in which a script-kiddie type is vivisected for providing the hero (acting as an undercover cop) with a key which he claims will provide access to an off-shore internet archive of copyrighted material. On the other hand, given the author's apparent views, you can't help but imagine that you're supposed to take a certain sadistic pleasure in the scene, even if it's just a joke. Since the author doesn't (as far as I can tell) ever present any middle ground, you're left with nothing to go on.

    I read the book hoping I'd find some interesting thoughts on copyright issues, and was disappointed. (I was also disappointed by the prose which, as the original poster pointed out, can be tiresome.)

    Why don't you ask the FSF since they wrote the license...?

    The license is irrelevant here; the question is what sort of agreement the employee in this case had with his/her employer. If they had a written agreement saying, for example, that the employee could keep copyright to the code if it was made available to the employer under the GPL, then that's OK. If not, then by default copyright law assigns ownership to the employer (the code in this case is called "work for hire").

    The admission that immediate supervisors didn't really understand the GPL, and the fact that higher supervisors didn't seem aware of the situation, suggests to me that there was no formal agreement, in which case I think s/he's probably screwed.... If the code clearly stated the employee's copyright claim since day 1 and supervisors have seen it and not objected, maybe that would be sufficient evidence of a contract. I don't know (and IANAL). But it would really have been smart to get a formal written agreement at the start.

    By requiring return notification, they can limit their liability, and take responsibility when appropriate.

    I don't understand how the notification requirement would limit their liability; in your air traffic control example, wouldn't it actually appear to *increase* the chance that they could be blamed? Someone could say "you knew about this unsafe modification, yet you took no action to warn of its risks", whereas if Apple hadn't been notified, the fact that they could claim complete complete ignorance of the modification would seem to help absolve them of responsibility for it. In the case that they did want to guarantee a piece of software for a given use, they could just make an individual agreement, independent of the license, with users that needed the guarantee, certifying a particular unmodified version for a particular use.

    In general, this is the obvious way to handle GPL'd software in critical situations where a user needs someone else to accept responsibility for software flaws; some entity (perhaps the author, perhaps a third party) can study a particular version of the code and promise to accept responsibility for it for a given use; I don't see that anything in the GPL prevents this. You're not preventing a user with which you make such a contract from modifying and redistributing the software, you're just giving them additional rights above those the GPL gives them, which apply only to a certain unmodified version.
