Re:Wesley Crusher jokes
Yes. This one (as stated in his blog):
Mr. T vs. Wussley Crusher -
Re:Oh, Hell, why not?The AV8B Harrier (a jet capable of Verticle Takeoff and Landing (VTOL), hovering, etc through the use of steerable jet exhaust nozzels) uses considerably less fuel when taking off like a conventional airplane than it does when taking off verticly. So much less in fact (I couldn't find numbers) that VTOL is almost never used except for nessisary training and operational necesity. This is because in an atmosphere, we can take advantage of Bernoulli's Principal to give us lift. Remember, there are four forces of flight: thrust, drag, lift, and weight (or stall spin crash and burn as a CFI I once knew used to say). You seem to be forgetting weight and lift. We're not talking about climbing stairs vs climbing a ladder here. We're talking about lifting something up with nothing but thrust and induced lift, if you stop applying force, it's going to fall. Still don't believe me, look at some numbers. Or do a search on Google for harrier VTOL fuel consumption.
Secondly, the X-15 (for which eight Air Force Pilots were awarded Astronauts wings as they entered the official minimum altitude for "space") was launched from under the wing of a B-52. And this was a program that started in he late fifties! Also, when the Shutle lands at Edwards Air Force Base in California, it's transported piggyback style back to Kennedy Space center in Florida by a specially modified NASA Boeing 747 Shuttle Carrier Aircraft. They have "launched" orbiters this way before for the purposes of approach and landing testing, so there must not be any unreasonable risks in seperation at those speeds / altitudes or with massive craft like those.
For your third point... um... either way, verticle or not, you're going to reach *vast* speeds and move huge amounts of air. One way or another, you want as aerodynamic a design as you can reasonably build.
Your fourth point... We definatly would not have been able to, if we had to strap a saturn V to a jet. But with a starting point of 60,000+ Ft, and 600+ MPH before you even light the engines, you don't need that large a rocket to push you the rest of the way, especially with more modern techlology tht we have today.

Re:don't botherNobody wrote DeCSS to teach you encryption, and you'll never convince a court that they did.
Not even if I show them this:

This isn't a real problemThis doesn't affect anyone who uses the correct method of getting a public key. AKA EMAIL (At worst)
It's only keyservers that this could occur on. Personally I keep mine on my web pages, anyone who wants to mail me securely uses that, or the one I mail them...
Rule: Only use keyserver keys for verification of an unknown source, and even then, if it's important don't trust it...
EG I get the CERT key from their web site
It's your security people, don't give it to someone else...

Re:Still SafeYou don't have to...
You just create an airburst bomb made of high-ex wrapped in powdered Uranium.
That'll screw people up just as definately as blowing them up will. It'll just be slower and less pretty to watch.
Of course, it'll cause far more mass hysteria, since the "Bang!" method tends to get rid of the people that get all hysterical about it...

Noise Killer or Alternatives
I seem to remember that Noise Killer used to be a fairly popular product back in the 80's. (At least in Europe) This temperature controlled fan voltage regulator could turn most PC "tractors" quiet.
Most computer fans are dimensioned for:
A) Extremely high temperatures and
B) Power supply maximum load.
Regulating the speed according to temperature makes a lot of sense, since these extremes are rarely encountered. In most systems this would also prolong the life of the fan.
Looking at their webpage , I find them quite expensive, and wonder if anybody has found less pricy alternatives?
Other than that, using a resistor to control fan speed can be tempting, but because of the relatively high start current of the fan, the fan might never be able to get started. A voltage regulator is therefore a much better choice.
However, I did at one point successfully use a 100ohm resistor to slow down a small, particularly noisy fan at the front of an old CD-R. To ensure that the fan would start, I simply mounted a 1000uF capacitor in parallel with the fan, which gave it the kick it needed to start.

But is wasn't GPLed!I have a copy of the cp4break.zip but it doesn't contain the GPL in any file.
But it does say: "You are allowed to mirror this document and the related files anywhere you see fit." Which is what I am doing
:)There is one file -Unit1.pas- which does say "CPHack v0.1.0 by Eddy L O Jansson / Released under the GPL" although the GPL is not included in the package.

Shame less plug...

Re:DVD lawyers "spill" secret code
Yes, I'm aware we've already had an article about this. I thought that seeing how one news source interpreted (reported) the events might be informative. Here's a Wired article on the same which even *includes* a link to de-CSS: DVD Lawyers Make Secret Public.
