So, explain how a "barnstormer" plane can fly upside-down.
Negatively cambered wings still cause fluids to take a longer path over the top at positive angles of attack (I don't have any wind tunnel pics to show you, but a quick google search revealed this interesting 1932 NACA wind tunnel study). It's less efficient, but most small aircraft still manage to spec a few negative G's as part of their flight envelope.
Yes, almost all aerobatic aircraft have symmetrical (zero-camber) wings, not to make their maneuvers possible, but to make them easier.
he thinks the speeding laws should be STRICTLY enforced, so that people would get pissed and demand that the law be changed
I'd agree with this, however the last time I protested a sign post by obeying it, it put me in a situation where I could have been in an accident (I did 25mph on a 25mph two-lane road that could have easily been posted 35mph in spite of its many curves) when the truck tailgating me decided to cross the double line to pass me.
the only difference between the speaker connection and the other connections is that the speaker connection only carries one channel (not 2) and is amplified.
That, and the ground on an unamplified cable is typically tied to case ground (in other words, the signal is "unbalanced" - like coax). Amplified speaker outs are usually balanced (equal but opposite + and - signals on both lines at any given time).
Ring voltage in telephone lines seem to be higher then the sound signal voltage, so the data connections that can happily coexist with voice lines without getting interference should coexist with sound.
Ring voltages are very low frequency AC (17 to 20hz) which no phone handset will reproduce. Although Ethernet is baseband (uses frequencies from 0-200mhz for 100mbit) very few signals actually get encoded into anything resembling 20hz. So it's difficult for a ringing phone to flip a bit.
Because audio is an analog signal, any interference will degrade the signal. It's just a matter of whether you can notice it or not. The original poster was more concerned about other devices inside a normal PC that tended to transmit at 0-20khz (the windings on a hard drive's seek arm are a biggie).
Ethernet's twisting works because it's a balanced signal - if the signal from an interfering line run in parallel to yours increases the level on the + line, the twists ensure that it will decrease the signal on the - line as well. The receiving card takes the difference which is unchanged.
cat5 can easily be used for a balanced audio signal (your phone line usually runs through a mile or five of unshielded cat1 next to hundreds of other cat1 cables). Do not ground the lines (they're not shielded). Put +/- outs for a channel on the same pair (they're color coded, for example, orange and orange-white is a pair). Because cat5 is typically 24AWG, I wouldn't run more than a few watts over it.
If you need to run a line-level signal over balanced pair, get a pair of baluns (they're short for balanced to unbalanced) and put one at each end.
Microsoft actually gives each employee administrator access to their own workstation. There usually isn't any attempt to lock the local workstations down. They even use FAT32 on the Windows 2000 master images.
I believe this is the primary reason why so many random things want administrator access on Windows NT/2000 and why the default file permissions/registry keys are so loose.
No, it's not, it's 16 bit. Sound cards do not feature 64-bit DACs. Some of the higher end cards have 18, 20 (most people consider this to be the limit of human perception), or 24-bit DACs, but definately not 64-bit, and in any case your source sound is 16-bit.
Or are you saying you can perceive the difference between your 1-inch deflection speaker cones moving an average of.0000152 inches too much or too little instead of.0000000000000000000542 inches? (I'm not completely sure but I believe the latter number represents less than one N2 molecule moved by the speaker cone, and it might actually be a fraction of an electron of output from the DAC.)
I'm encoding all my CD's with Ogg now, using abcde 1.9.10 which does oggs now by default.
It sounds better, it takes up less space, and I'm not infringing any patents. Sure, it takes a little longer, but it's worth it.
By the way, you shouldn't ever convert mp3's to ogg's. You'll get a noticably degraded ogg, since you're losing information from both psychoacoustic models (which were never meant to be layered). Encode all your Oggs from lossless sources and leave your existing mp3's as-is. After all, there's lots of software out there that can play both.
a GPS unit (so you know where you are), an amateur HF radio (so you can tell others where you are), and a big battery (to power either, if necessary, and to make sparks to start a fire).
Everything else you can usually find on the island (shade, moisture from various places, firewood for signaling, etc).
but Wankel rotary engines are about 20% less efficient than water-cooled piston engines. This can be attributed to the combustion chamber on a wankel moving around - more energy is wasted when the case is heated up more evenly.
They probably make sense in a ducted-fan VTOL machine though - less weight means you need a less powerful engine to provide a controlled descent during engine-out scenarios.
You probably want to set up a digipeater. This might be as simple as putting a solar-powered access point on the mountain and aiming cards at both sides at it.
If you want to take the purely passive approach,
find a way to keep a large area of 1/2" or finer chicken wire in a very flat plane and use that for a mirror. You might want to temporarily attach an optical mirror to it and use a laser to check the angles. Make sure this setup won't sway in the wind.
is it a good idea to intentionally "de-tune" an antenna, to reduce it's output to just what you need (as opposed to using an attenuator).
I would say no. There's only a couple places that power can go:
Back down the coax to the card (higher standing wave ratio). This may or may not matter for 30 milliwatt 802.11 transcievers but it does matter for anything over a couple watts.
A direction you didn't want. Less directional antennas don't have as much gain in any one direction.
A harmonic you didn't want. Luckily there's not much to interfere with at the higher frequencies yet.
I noticed a distinct lack of any math on the primestar link page - is making an efficient waveguide really as easy as stuffing the center conductor of some coax a ways (1/4 wavelength, right?) into the side of a tin can and saying "that looks about right?"
Libc6 uses symbol versioning. An application originally linked to glibc version 2.0 symbols continues to operate using the glibc 2.0 ABI even after glibc 2.2 is installed. However, an application linked to glibc version 2.2 won't work until glibc 2.2 is installed.
LEDs aren't as bright as incandescent flashlight bulbs, so most LED flashlights use multiple LEDs.
There's only a couple ways to change the focus on something like that, and the most practical method so far is to use LEDs with a variety of focal lengths and alternate between them in various duty cycles using oscillator circuits. The article discusses that.
Properly engineer the interface to everything an outsider can get their hands on (parameters to cgi scripts, random services that shouldn't be running or exposed to the outside world at all, physical security, etc) and make sure you can trust your insiders.
Unfortunately it's very difficult to turn 100000 lines of crap thrown together over six weeks of all-nighters (or 1000000 lines of crap thrown together over six years) into a properly engineered system. In fact it's usually significantly easier to throw it out and start over.

For example, the artificial horizon gyroscopes in aircraft do not precess.

I'm the author of abcde. It's been five minutes since I read your comment and I'm still laughing. That made my day. Thanks :)
Not that Windows machines would place very well anyway...
To a person who upgrades their computer every five years, this is only a selling point if they believe you. :)

Yeah but noone wants to go after Procom for their violations.
You'd be surprised what just dumping stuff into a cloud can do.
Umm, right. That's 8.4 gallons per minute - a garden hose puts out that much, and it's got 60psi and a 1/2" "barrel".

Check out http://www.gnu.org/software/libc/FAQ.html#s-1.17, and try objdump -T sometime.
Done. Abcde 1.9.x defaults to Ogg.
