    "Firing Customers" is quite possibly the dumbest thing I've heard today.

    No, in certain unusual situations, it's the best thing you can do. (And it's a term I've heard for many, many years.) I worked in a graphics/print shop for a while, and some customers would drive us nuts, and lose us money over the stuff they did. ie. bring in questionable originals for copying, choose the cheapest photocopy option available, then return a 10,000-sheet job because there was a speck in the copies. Or, in a low-end design job, argue over nickle and dime issues for hours, eating up the designer's time that should have been spent on better-paying work.

    A few times, we gave them the phone number for a competitor, and told them not to come back.

    In the service industry, the customer who is paying the least, will invariably demand the greatest amount of service and attention. Big dollar-customers know what they want, know the value of what they are purchasing, and trust you to do it properly. I imagine there are similarities in the retail industry.

    PHP's problem is that it quickly becomes unmaintainable in larger projects. That's why it doesn't scale, not because the platform isn't fast enough or Apache can/can't scale.

    Hmm, maybe you've heard about classes?

    All of my recent PHP projects have had 90% of their code in various classes, with the rest just gluing them together and calling the class functions. Very simple to maintain, and it solves the whole namespace issue very nicely.

    ...having many persistent connections to your db can be an issue. Mysql tends to get extremely unhappy at the 1000+ connections range.

    Mysql is not the only one. Each DB connection takes up system resources and database resources. A few years ago, I saw an Oracle database brought to its knees when our website got hit hard, causing well over 2,000 simultaneous database connections. It wasn't the main Oracle process that was the problem, it was the resources that all the listeners were consuming. Re-allocating more resources to the listeners solved the issue, but that takes resources away from the main DB engine. The Oracle server in question was a dual-processor E450 with 2GB RAM.

    I love PHP, I use it almost exclusively for web apps. But I have serious misgivings about its scalability due to a lack of managed database connection pooling.

    Wow, where to start...

    First, it is not possible to move significant amounts of men and materials around the world by anything other than water. If the Air Force mobilized every one of their cargo aircraft, it would have taken a few *years* to deploy the troops needed for Gulf War 1.

    Second, the Navy has provided a large portion of air combat assets in every conflict, and has been able to do so immediately, since they're already in the areas they're needed. Deploying a single Air Force fighter squadron into a combat zone takes *weeks*. Additionally, the Navy carriers are out of reach of most enemy forces, whereas the air force squadron will need ground units to provide security.

    Third, the vast majority of cruise missiles expended in recent conflicts have been from naval vessels.

    Fourth, the Marine Corps is part of the Department of the Navy, and like the carrier groups, we have several Marine Expeditionary Units deployed on ships in strategic regions at all times. Those MEUs can usually reach the combat zone and be on the ground in a matter of a couple of days. Contrast this with the weeks to months that it takes to deploy an Army unit of equivalent size.

    Fifth, the electronics suites on Naval vessels provide both a high-quality sensor network, as well as electronic countermeasures. This is even more advanced when combined with carrier-based AWACS and ECM aircraft.

    Yeah, sounds pretty pointless to me....

    OTOH, if we contracted out the cargo operations of the Air Force, we could probably easily live without them. Those whining crybabies don't go anywhere without their air-conditioned tents. Talk about a waste of money...

    I was thinking of a range finder on top of the vehicle aimed down towards the ground so that on flat terain it is taking the hypotenuse of a right triangle with a point just about 300-400 feet in front of the vehicle at full speed.

    Hehe, never done any night-time off-roading, have you?

    To be useful at moderate speed, you'd have to mount that range finder on a mast about 20-30 feet tall (or more).

    Seriously, off-roaders mount their lights on top of the vehicle in order to illuminate over variations in terrain. Now, if you want to find out what that range finder would see, find someone with an ORV to take you out at night. The lights will illuminate out to several hundred meters easily, but you will have many "black holes" within your field of view, caused by shadows of small rises.

    Take everything I said about speed in the previous post, and divide by a factor of four when running at night. (And that's essentially what you'd be doing when driving with your range-finders.) That four-foot wide "black hole" in front of you could just be a slope slightly steeper than the angle of the lights, or it could be a 10-foot deep trench. There's no way to tell until you're within several feet of it. Given the possibility of it being a trench, you'd better not be going fast. Typical washes in the desert often have vertical or undercut banks, dropping anywhere from six inches to six feet. Six inches will give a pretty good jolt, six feet will destroy the front end of the vehicle.

    Me? I'd want one of those "birds" Speed Racer used for recon. Something flying up to kilometer ahead, mapping the terrain with above ground radar. :)

    As for building it to "ridiculous strength", yes you can. But remember that the stiffer/heavier it is, the more shock it will take on every bump. Welds can break under those kind of conditions. Personally, I'd build it to be light, small and flexible. Think sand-rail rather than HMMWV. This also makes it less likely to get stuck/high-centered, etc. Also more likely to survive a high drop than a heavier vehicle would.

    Another way to deal with it is with a range finder angled towards the ground- if it's suddenly WAY steeper in front of the robot than the robot was expecting, turn around and find another way.

    Speaking as a former off-road enthusiast, unless that range-finder is suspended a couple hundred feet in front of your vehicle, it's not going to do you any good if you're moving at 60mph. Stopping on natural surfaces can often take a lot more distance than you're used to, especially if there's a downgrade involved.

    Add to that the fact that hitting an 18" deep cut in the surface at high speed can tear the wheels right off the vehicle...

    Seriously, running at 60mph on established, familiar trails in the open desert will keep your brain running at full speed trying to keep you safe. Running at anything over 40mph in unfamiliar, non-graded landscape is seriously risking your life. Most of the time I never got much above 30mph, and even that was hard on the vehicle.

    Ah, here in AZ, speed cameras are used, but I've only seen them in vans, where I believe there is a human operator. Though, grant you, the odds of that operator being in any way aware of things is practically nil. Which, BTW, is my real beef. When I trained to use speed timing devices, my instructor made it very clear that the device was only to confirm what I already knew from my own observation. At that time, I could tell you the speed of a vehicle to the nearest 5mph with better than 95% accuracy. (I doubt I could do it to 50% accuracy now, it takes constant practice.) Without the trained eye to back it up, it's impossible to prove one way or the other whether the device was functioning properly at that moment in time.

The first two are not much of an issue anymore, since the state now controls training of *all* police officers, and oversight of municipal governments is now pretty tight. The last one still holds though. The State troopers like their exclusive use of radar.

    It doesn't really hinder the municipal cops much though. As long as it doesn't emit a doppler signal or use rangefinding, it's OK for use (VASCAR, speed tapes, stopwatch, etc.)

That way, when a provider finally does clean up their act, they don't have to try to track down the thousands of private block lists they're in. Believe it or not, some of the most egregious violators really are cleaning up their act lately, cough, Verio.

    As for no false positives, well, unfortunately, that's just not an option anymore. By only blocking the specific IPs of spammers, it leaves the door open for ISPs to continually shift their spammers into "clean" IP spaces, leaving a trail of blacklisted space behind them, and forcing admins to play a game of spammer "whack-a-mole". It's far simpler to just block the ISP's IP space in it's entirety if they choose not to disconnect a spammer, and believe it or not, much better for the ISP's non-spamming customers, who would have ended up in polluted space anyway. This way, there's only one entry to be removed when the ISP gets a clue, instead of dozens/scores of individual entries that must be tracked down and cleared.
