Doesn't take much.. Pinching the cable or bending will commonly shift it and undo the twisting in that area.. I suspect the main reason, though, is to avoid induced currents, whether from an emp or leakage from the radar / transmitters.
But this raises the question: Why are you using shielded ethernet? Ethernet is differential, and thus pretty immune to common mode noise.
Probably to reduce emissions.. Most boats have a lot of sensitive electronics.. and when you're under EMCON, you don't want anything avoidable to emit. Also, consider you'd want to make at least a minimal attempt to harden the equipment against any kind of EMP.
Had a friend that worked at a naval shipyard.. spent weeks trying to locate, identify, and eliminate undesired emissions from various (uncertified and certified) electronics.
Why? It's crippled, intentionally. Everything gets re-encoded into their proprietary compression (which admittedly, isn't bad, but it's another layer of loss.)
You can now download to the unit faster with the MD stuff, but unless a new hack has come out, you cannot upload at high quality, even content you have recorded.
I was considering a cheap one for portable recording, but ended up with a laptop and an Eiderol/Roland UA-5. 24-bit recording, decent mic-pres, and a bunch of analog and digital ports.
[Cough] I don't think you've spent much time around horses.. when was the last time your car ran off at a tanjent at full speed because it saw a leaf blowing? Or that it went off and started attacking another car because it didn't like the set of it's mirrors? Or decided it didn't want to go somewhere and just stopped (well.. that one's debatable..)
Besides, you get really strange looks going through drive-throughs.
The ATI All-in-Wonder devices are nice, but there are some caveats: 1) They don't use the same colorspace as the BTTV cards.. the programs have to be able to handle YUV input. 2) Last I checked, the drivers didn't decimate / resize frames / fields; you got 59.97 fields of 640x240. 3) No mmap support.
Given that, the drivers were remarkably efficient and stable. I was working on VBI and closed captioning, but didn't get a stable release out.
This is fairly old information (since my dev box died), about 4 months out of date. Check out http://gatos.sf.net
For linux video, the best supported cards are bt8x8-based cards, including most of the WinTV line. Many of which do have have svideo and composite inputs, as well as tuners.

Now, it's super important that the SRBs (solid boosters) are lit up at the same time. They're far away from the center, and and being solid, they can't be throttled. If just one of them were to light, that would be another shuttle lost, right there.
Oldest story where they used the same mechanism (modulating an audio signal onto an ultrasonic frequency and sending it to people) is a story by L. Spague de Camp, _The Exalted_, first published in 1940. (Fun story, by the way; my copy is from _The Astounding Science Fiction Anthology_, edited by John Campbell, Simon And Schuster. Publication date is roughly 1952.)
"There's the soft-speaker, for instance-" "What's that?" "It's like a loud-speaker, only it doesn't speak loudly. It throws a super-sonic beam, modulated by the human voice to give the effect of audible sound-frequencies when it hits the human ear. Since you can throw a supersonic beam almost as accurately as you can throw a light beam, you can turn a soft-speaker on a person, who will then hear a still small voice in his ear apparently coming from nowhere..."
Fuel, yes, but if you want to keep your plane nice and shiney it'll take a lot of maintainence.. Fuel, bugs, pollution, exhaust.. I watched my friend polish just the _spinner_ on the airplane for 45 minutes just to get that mirror effect..
And when's the last time you were successfully able to follow the rule of thumb of keeping a car length between you and the car in front of your for every ten miles per hour you were travelling?
Rule of thumb we were taught in driving school is a 2-3 second gap; and yes, I usually manage to keep that, even when at highway speeds (65-70 here, 75-80 further south with the high limits). Why? I drive a tank (aka '82 oldsmobile) and am well aware of it's stopping characteristics. Main problem is people who think my buffer zone is a perfect passing lane, but that's usually easy to compensate for (let off the gas a little, regain space, speed back up to normal speed, or shift lanes.)
One thing I wish people would do more often is reserve the far left lane (non-HOV) lane for passing. It's law in some states (NJ, any more?) and works well until traffic saturates (*cough* turnpike *cough*). It's still fairly common to find a pair of cars blocking both lanes doing 5 under the limit here.
My age? 22. Accidents? 0. My insurance? Still high.
We've had two of those ('82 Oldsmobile 98 V8 350 Diesels) and they were a constant source of income to our mechanic until we put a '78 gasoline engine in it. Once we replaced the starter and flywheel as well, it's been remarkably reliable aside from ongoing trouble with the power windows. The 2nd one's in the back, for parts. Just finished rebuilding the brake system (myself; about $80 in parts to replace the wheel cylinders, calipers, and master cylinder; not bad on a 20-year old car.)
It's main attraction right now is that it is cheap, (no payment!) and that it has room.. Very few recent low-to-midrange cars have enough headroom for me, and I'm only 6'1". And I even fit in the backseat..
They said 'Give it away' but they meant 'License it for a small royalty'.. $.02/sq. ft. or some such. But it did go from Trade Secret to Cheap Patent because of the Mob and Moneyed Interests. And there was the obligatory reference to secret, high-milage car. Good short, have to dig it up again. But yeah.. it was high, once they removed the visible light filters. And 'made from common clay' or something.
Dunno.. we have an old 52" Zenith Rear Projection with a faint burnin from a badly designed VCR (no way to disable the display from the front panel; ALL functions should be available without the remote) and a broken remote.
Last time I was playing with the Windows Media Encoder there was an option to encode ISO-compliant Mpeg-4 streams. As for open source, VideoLAN is pretty good, except for their live streaming (only supports some random hardware Mpeg-2 encoder, last I checked). I know there are Mpeg4 streaming tools.
The only drawback in my mind is you cannot use the USB interface for 24/96 audio. That, and some issues like jitter and delay, should be solved by the next generation of IEEE-1394 interfaces.
Eh? The UA-5 _does_ do 24/96, but only half duplex. (The manual sample rate setting is not the most user-friendly, but it works..) I did see a few dropped samples, but it performed very nicely recording on site. Just make sure to get some decent mics.. the difference between a PA-grade mic and even a low-end music mic was very noticable.
Crew members for any permanent base on Mars should be selected to have absolutely no agressive tendenscies. Then humanity might live on when the earth erupts into a ball of mushroom clouds.
Except they'll probably be dead on their own.. Meek / passive people don't make the best pioneers, aggression is a survival trait in primitive situations. It's only lately that it has become a drawback...
Cobra is from Zahn's earlier writings.. can't remember if it's back in print at the moment, you may have to comb used books stores. It's a very decent example of military sci-fi, but has an... aged feel. Much the same tone as a lot of novels from the Vietnam war era.
I haven't read too much of Zahn.. Warhorse was an interesting standalone, and not too stereotypical. The Thrawn trilogy is very good, IMHO head and shoulders above the rest of the Star Wars novels. Spinneret was a good, light, read. Deadman switch is, well, weird. It's a suspense novel, so it isn't nearly as good a read the second time, but was quite riveting the first time.
.. just checked. Cobra, and it's sequels (which I have not found) are all out of print.
If you like Military Sci-fi, I heartily recommend David Webber's Honor Harrington series. The first two books in the series are available in the Baen Free Library.

I thought the reason was that since we couldn't even figure out how to use the metric system, we had no hope of figuring out the euro.. :)

Of course.. and everyone knows that an annoying NASA robot can start just one to force a launch.
Bell Atlantic + Nynex (sp?), IIRC.
However, it appears it is illegal to use self-same scanner to:
a) Listen to the Cell Phone band
b) Receive certain satellite transmissions.

Eh? 1 MB/s is roughly what you can get on an unloaded 10 Mbit connection. 1.5 Mbit tops out around 150-180 KB/s.
