  1. Solve traffic jam waves yourself on Automobiles Evolve to Live Up to Their Name · · Score: 2, Interesting

    You can do something about it, if you care to. The biggest causes of stop and go traffic jams on freways are onramps and offramps, and the "gotta win" mindset that doesn't let people merge into traffic flow or change over to exit flow. Start leaving a few car lengths of space ahead of you when you drive on freeways. By doing this, you're giving people room to merge in and out, and you're also giving the wave time to break up before you reach it. I've gotten into the habit of doing this, and wouldn't you know it that if I leave enough space ahead of me, traffic jams just seem to break up right as I approach. Most times, I don't even have to brake as I come up to them.


    Yes, people will move into the gap you're leaving. That's the whole point. Most people in traffic jams don't try to change lanes, so they won't know or care that you have a few car lengths of space ahead of you. For the people that do care, they're free to move into that space (when they do, just open up another car length of space). You don't even have to go slow to do this. A few miles per hour slower than the average speed will easily open up a nice gap you can carry to the next traffic jam. As the traffic clears, you can speed up. If you do find that you misjudged your leading distance and end up having to slow or even stop, just pause a moment before starting again. That will open up a space in front of you.


    None of this would be necessary if people actually had adequate driver training, but sadly that's not the case in the States. Driving is consider a "right" rather than a privilege, and driver training suffers because of that (Joe Sixpack or Jane Soccermom will throw fits if they fail a driving test and have to give up their license).

It used to be that progressive-scan players were prohibitively expensive, but now you can find them for $100 or less (though I'm not sure how good the quality is on the lower priced units). I remember paying $800 for a Sony DVD player a few years ago that didn't have progressive scan (back then, that would've set me back at least $1000, if not more). I upgraded that set not more than a year later to a better model that included progressive scan for only $500. And that's still 2-3 times what you would pay for a good player today.

    I think where Tivo will make the most headway will be with smaller cable networks. The problem is, there aren't very many of them left. Why do I say this? The major networks (all of whom either own major cable channels or have major investments in cable providers) are wholly against Tivo poaching "their" ad dollars. Their attitude is that if they're going to allow Tivo to put up adverts (and they need to pass some sort of signal to provide this capability) then they want a cut of the action.

    I don't see why networks should have a problem with this. The Tiivo bits are in addition to the ads showing on the networks. Advertisers still have to pay for the spot. They can then decide to pay Tivo a bit extra to show up in the Showcase and get the "More Information" banner. Networks "win" because they're not losing the ad revenue (the ad still has to run). Tivo wins because they're providing a huge benefit for advertisers.


    The thing that worries me most about this model is if it runs into the same expectations and problems as web ads. If Tivo is selling Showcase ads with the promise of some number of sales based on hits, that won't work. It's still advertising with the goal of creating recognition, not directly selling product.

    One of the things that make Unix truly great is the possibility of piping one program's output into another. Use the full potential of what others have developed, don't reinvent the wheel.

    What do you do if you need more control than piping will allow? The difference is between working with data and working with objects. In *nix, you're piping data across processes that act upon that data. If you want to change the password for all of the users on your system, you're iterating through /etc/passwd and passing the username to passwd to make changes. In Windows, you're iterating over a collection of user objects, which have methods you can call to change passwords. You're not reinventing the wheel, because you're not implementing how that password is changed (I've seen the wheel reinvented in unix by trying to encrypt passwords and write those values directly to /etc/passwd or /etc/shadow, bypassing passwd completely). In fact, if you're not using automation objects in your Windows scripting, you're not using "the full potential of what others have developed." If you're writing a unix application, you should make sure it's scriptable via piping. Similarly, if you're writing a Windows application, you should make sure it's scriptable via automation interfaces (IDispatch). One is the standard for *nix and one is the standard for Windows. Nobody is saying that *nix should ditch piping in favor of a COM-like architecture, so why should Windows ditch COM automation in favor of piping?


    It was after reading a book on ActiveX that I definitely quit on Windows programming.

    I'm curious why. Was it too difficult or obscure? Did you have architectural or security objections? Or were you so entrenched in your *nix ways that you couldn't grasp why you should use a different approach in Windows?

    Exactly. What makes shell scripts so much better on Unix isn't really the shell, it's the flexibility of the programs that come with a Unix.

    That's true, but the fallacy is that you're assuming Windows should be scripted in the same fashion as *nix. That's simply not the case. Batch/Command scripting is nice for small bits, and can actually be fairly powerful in an obtuse sort of way, but the real power in automating Windows comes by using the Windows Scripting Host, JScript or VBScript, and all of the ActiveX/COM interfaces into the functionality of the OS and other applications. A classic example is iterating through users. In *nix, you write a shell script to parse through /etc/passwd. In Windows, you write a jscript to instantiate the objects that deal with Active Directory, and iterate through user objects (each of which you can perform actions upon, wherein *nix you'd have to invoke other applications). One approach is not necessarily "better" than the other, but you can't assume that your *nix administration experience will directly translate into Windows administration. You'd laugh if a Windows admin felt the reverse was true. What really gets me is when people complain about Windows not being automation-friendly because they're used to *nix scripting. Yes, you cannot pipe notepad.exe into winword.exe, for example, but Word has a very rich automation interface that you can hook into and use from a simple JScript.


    Take the DELETE command. It has trouble deleting multiple files at a time. It can't delete directories. Then look at Unix rm. It's easy to see why batch files are a joke.

    What? Try running "help del" from a cmd.exe window some time. Also, look at "help rd". If you want to remove a directory tree, you use the "remove directory" command. "del" deletes files. "rd" deletes directories (and can delete files within directories if you tell it to).


    The shell itself is definitely more flexible overall, though. Definitely more scriptable. The Bourne way of doing conditions, loops, pipes and whatnot are definitely more intuitive, more flexible, and carry less baggage than command.com or cmd.exe.

    Consider cmd.exe to be the functional equivalent of csh. It's a decent interactive shell, and has some good functionality (especially later versions of cmd.exe in win2k and xp), but you'd have to be nuts to do any extensive scripting with it. Just as you'd pull out bash or perl to do more complex tasks in *nix rather than using csh, you should use WSH in Windows for more complicated tasks.

Now, should the speed limit be change? Keep in mind that there are children playing nearby and several pets have been struck and killed due to speeding motorists. No, the solution isn't always to either remove the law or enforce every infraction. In this case, either speed bumps/ditches could be installed or they should have cops out enforcing the speed limit during times when children are likely to be outside playing.

    The road is obviously conducive to speeds higher than 25mph, regardless of the safety issues that may cause. Most likley it's because the road is wide, smooth, and relatively new and well tended. If the road were narrow as in many urban residential areas, there would be no problem (too cramped to go fast). Suburbanites won't accept that kind of narrow road, though, so we need another fix. You can't just change the speed limit and do nothing else, because it's unenforceable. No, the proper thing to do is to put in speed bumps placed at a proper distance and of a proper size to ensure most people can't reach more than 30mph before they hit the next bump, and must slow to 15-20mph to traverse a bump or risk damaging their car (yes, there are some sports cars that could accelerate to 60mph in that time, and there are big 4x4s that could roll over the bump without noticing, but you plan for the average). This cannot be done on a highway, though, so how do you deal with a four-lane divided highway with a posted limit of 55mph and an 85th percentile speed of 70mph? Even if you increase cop coverage you can never catch each infraction because a huge majority (85% or more in this case) of the traffic is breaking the law. The proper solution here is to do surveys to determine what the 85th percentile speed is on the road, and then adjust the speed limit accordingly (and revisit this every several years to make sure the limit is still reasonable). Now you have a just and lawful limit backed by facts, and the occurence of speeders has dropped to 15% or less of the traffic. That's a manageable number for police to enforce, and thus we can keep the speed limit.


    Even choosing a proper 85th percentile speed is not always enough. A wide open stretch of desert highway limited to 60mph is insane. You have visibility for miles and generally low traffic (especially if it's a three-lane highway), which means you can safely drive as fast as you and your car can handle. This would be a "reasonable and prudent" limit, where you are expected to judge your own abilities and those of your cars and stay within that limit. Enforcing this would involve discretionary judgement on the part of police officers, but in this case it would be built into the law. The law is not hiding the fact that it's partially up to the office when and where to enforce this law, unlike many laws today that implicitly assume that they will only be enforced sporadically.


    There are district attorneys who pressed states to set required punishments for some crimes, leaving no discretion for the judge. The result? Overflowing prisons and grave injustices to the individuals punished in this way (such as the kid serving 10-15 years in prison with no chance of parol for having sex with a girl one year younger than himself (17)).

The Duke or original is just a bit too large, and the buttons a little too harsh, though with the proper grip it stays comfortable in the hand for hours.

Since most games will make that final click do something other than the initial sweep of the trigger, you're stuck trying to hold the trigger at full press minus the click, which can be strenuous since the spring in the triggers is much weaker than that of the XBox controllers. Add to that the ... funky layout of the face buttons, the useless and poorly positioned Z button, the Gameboy-sized d-pad, and the wonky sticks (the main stick is straight off of the N64 controller, with a bit of added grippy rubber, and the C stick is just ... weird), and there's not much more to say about the cube controller except that it's more comfortable than a dual-shock.

If you top right up to the cap you're either going to have a big corrosive mess of spilled fluid or you're not going to be able to brake at all.

    So running a 1.8T at boost pressures up to 18 psi with gasoline isn't much different stress-wise than a normally-running Diesel. In short: the 1.8T is fricken' strong.

    I'd start to worry about charge temperature at 18psi boost (I'm not familiar enough with the 1.8T setup to know if they typically have quality intercoolers, or any intercooler at all). The diesel-based block may be able to handle it, but what about the rest of the intake/exhaust system? You'll also have to bump up to premium gas if the car didn't require it already to prevent detonation caused by the higher temperatures.


    This is a common trait amongst most turboed engines.

    Yes and no. Forced Induction (FI) engines must be stronger than NA engines simply due to the nature of forced induction, but that does not necessarily mean that they are strong enough to handle overly increased boost. Just as I would be very wary about bolting a turbo or supercharger onto the NA engine in my car, I'd also be very careful about increasing the boost on a turbo car without doing a lot of investigation first.


    Then again, the only turbo I've driven is my big-ass F250 turbo diesel, and it only spools up the turbo past 1500rpm or so (redline at 3000rpm, normal cruising at 1000rpm). However, ECU remapping for my truck could gain me upwards of 50+ hp and lb/ft. My car would be lucky to make an extra 5hp with just a chip change.

    As many others have pointed out, chipping a car is nothing new. However, many people have unrealistic expectations about reprogramming their ECU. In the article, they mostly mentioned turbocharged vehicles like the Jetta TDI or 944 Turbo. The BMW owner mentioned was unsatisfied with the change because naturally aspirated (NA) cars don't benefit well from remapped ECUs.


    Modifying a car's ECU mainly just adjusts air/fuel mixture, but on a turbo car it can also increase boost pressure. This is where the main hp gains can be found, but is also where you'll likely blow your engine. A NA car will need more modifications than just a chip to get anymore than a nominal power increase. Intake, headers, and exhaust are all necessary to increase airflow to take advantage of a performance chip. Even then you can generally only expect to make another 10hp at the very top end of your hp curve, and you might even lose torque at lower rpms (torque gets you up to speed, hp keeps you there).
