While I am not disputing what you are saying, I believe shelling can also be hugely ineffective. In Fred Bridgland's book A War for Africa he tells of how South African G5 (155 mm) shells were unable to injure or kill enemy soldiers if landing more than 3m from the target. Bridgland attributes this to the thick sand in which the shells landed.

In Vim you can jump to the man page of the word under the cursor with "\K". "q" gets you back. I wrote a Xlib app a while back and found this to be very nice and quick.
Once while hiking in South Africa I noticed a blurry movement off the left side of the path. That is the only thing I remember seeing, a faint blur. The next thing I remember is standing about 20 metres down the path looking back at the Cape Cobra hovering next to the path.
My only explanation for the lack of other memories (I do not remember running or jumping) is that the decision to run was made instinctively, and was hardwired into my brain without me having to go through the whole consious decision-making process. I would definitely disagree with with you that fear of snakes is learned behaviour, your body will make the decision for you - a long time before your brain has had time to react.
When you notice the snake from further away (my guess is 5 metres or more) , you do not have the instinctive reflex to jump or run (in my experience). This allows you to be a bit more composed about how you react.

Sorry, but undereating is a contributing factor. It causes your body to store more calories as fat. Also, I said that it was a combination of said factors. Now, if you're talking about bulemia or annorexia, that is a whole other topic, and not one I feel comfortable discussing.
You don't make sense. Say for example that during an average workday I burn 2000 calories. Now you say that by only eating say 1500 calories (which is what I assume you mean by undereating) I will gain weight? My body cannot magically create 500 (or as you suggest, more than 500) calories to suddenly pack around my waist as fat. The first law of thermodynamics states that the energy must come from somewhere (you cannot create or destroy it), and becoming fatter by undereating totally ignores the physics involved.
It's a scientific fact that obesity is rarely caused by "lack of control". In order for overeating, or binge eating, to be a significant cause of obesity, you have to eat so much that you're more likely to die from overconsumption.
Obesity is more often caused by combining the following: Undereating, Eating nutrionally-deficient foods, and a sedentary lifestyle.
No it isn't. Dude where the hell did you get this? Don't you understand the physics? It is impossible to gain weight when you are eating less calories than you are using. So if you are "Undereating" you must lose weight! Every self-respecting geek should read the Hackers Diet before posting bull like this on/.
My advice? Get up, go outside, eat something besides pop and chips, and stop starving yourself out of guilt. Also, a positive mental attitude seems to have a huge impact.
That however, is good avice.

Incidentally, the limit on elevator speed is human tolerance for changes in air pressure. 8 meters per second (downward) appears to be the comfort limit. The Sears Tower elevators were originally set for 9 m/s, and a broken eardrum was reported.
Humans have a much higher tolerance. In the South-African gold mines (where I occasionally have to work), people-carrying elevators (cages in mining slang) are allowed to travel at 15 m/s and ore-carrying cages can travel at 17 m/s. At 15 m/s there is no (to me at least) noticeable discomfort.
Skydivers travel downward at about 60 m/s during freefall and afaik do not have eardrum issues.

While you are correct about the regulators being able to ourput the desired voltage, they will not usually be able to provide enough current. A normal LM7805 in a TO220 package can deliver 1 Amp with a heatsink (typically, check the datasheet for exact info). That is only 5W. In some cases (external modem) you might be able to get away with it, but in others (ethernet hub) you might not.

The Morex case doesn't have an internal power supply. It has an internal DC-DC power supply, which means that it has an external wall-wart to convert AC to DC.

Limux's approach to swapping memory is pretty awful for this type of application. After a long period of idle time, attempting to play a movie results in about a minute of vigorous disk-thrashing before anything actually happens on-screen.

Under the 2.6 linux kernels you can control the swap behaviour by changing the value in/proc/sys/swappiness. if you do "echo 100 >/proc/sys/swappiness", it will swap very easily (for things like file buffer etc.), if you do "echo 0 >/proc/sys/swappiness", it will only swap if it absolutely needs to. I personally use a value of 20, which for my purposes, works nicely. hth
I wrote that sig before the last matrix movie came out, thus I was unaware of the extreme forking abilities of the agent_smith program.
Although your solution is correct if the agent_smith program is continually forking, the agent_smith program does not continually fork. It forks to fill available space and then stops. Killing a single instance after the agent_smith program has finished forking does not cause it to respawn (I cannot remember any of the agent_smiths in TM3 respawning after being zapped by neo - could be wrong though). SO if my.sig were to be run at a time when agent_smith has finished it's forking process it will still manage to get rid of all the instances of agent_smith
But even if agent_smith forks constantly, you do agree that you cannot keep your while(1) running forever since that would be too much of a drain on neo and the system. And in that case, the moment you kill your perl script, the agent_smith program will be started from a cron job a few seconds later. So to solve the problem completely you have to killall -9 crond; killall -9 agent_smith; but killing crond will have catastrophic effects to the whole of the_matrix. So it is only a temporary solution anyway.
At any moment in time the equation V=IR holds for any circuit (yes, even AC circuits). It is just that when you have caps and inductors in your AC circuit their impedance changes all the time, making the V=IR equation less usefull. When one only has resistive impedance elements it is possible to use V=IR for AC circuits by replacing V with Vrms, and I with Irms, the Root-Mean-Square value of the AC voltage or current, giving Vrms = Irms*R.
when the car was moving wind power would convert the hydrogen?
No. Turning the turbine requires energy. In your scheme above, the energy has to come from the car since the movement of the car is creating the "wind". In effect, you want to use the energy that propels the car forward, to create more energy to propel the car forward. What you are describing s a perpetual motion machine.
I don't understand any of the science of it. so it is probably a stupid idea
Action: photons from a star push against sails from somewhere near the front. Reaction: ship pushes back and moves further away from the star. You can't "tack" in a vacuum.
Actually the force generated on the solar sail is in the direction opposite the reflected photon. If you rotate your sail, the photons will be generated in a different direction than the one the light is coming from, and thus your force vector will not coincide with the direction of the light. You can "tack" using solar sails.
