The 137MHz transmissions are due to be phased out after the next NOAA satellite launch. So, it'll probably be good until 2010-2015 when the satellite being launched now gets phased out (or it's APT system fails). Note that while there are only 2 active NOAA satellites, there's normally two older satellites still transmitting in backup duty.
After 2010 or so the HRPT (High resolution picture transmission) digital system will be the only system in use, which requires a tracking antenna and a digital reciever at 1700MHz. The HRPT signal is not encrypted though, and does give better resolution (1x1km vs 4x4km) and more image channels (5 instead of 2)
People can put out a reasonable amount of power. Remember the tire-mounted generator and (admittedly tiny) headlight on your pushbike?
A human can put out a couple of hundred watts continuously, possibly 500 watts for a small amount of time. Five 3W luxeon LED's (with a suitable storage) could be run for 10 hours, if you pedal casually on a bike for an hour. Those can easily light up a large room or two.
yes, like when I'm watching my TV, and a man comes on and tells me how white my shirts can be. But he can't be a man because he doesn't smoke the same cigarettes as me.
For some reason, I can't get no satisfaction from that. Maybe I need professional help.

Seems logical to have their funding cut to me, do they really need _daily_ monitoring? Would monthly monitoring not be more practical, after all it will take many years before the next interesting event happens. But what about this scenario?

FM has limited bandwith (11kHz or so for a good reciever).
You will lose all the high frequency component of audio cd's, so why bother encoding it in the first place? You could encode 128kbps stereo MP3 at a 22 (or 32) kHz sample rate and there would be no percievable difference after FM broadcast to lossless encoding (with a decent encoder, that is)
Then at least they could go to a raid array with *some* redundancy.
The solar wind is a gas with a certain density - a very low density, compared with sea level atmosphere, but it's still a gas, and molecules will still bump into each other in it. So, sound (this is, pressure waves) can travel through the solar wind. You wouldn't be able to hear it, but it'd still be there regardless.
If you are moving faster that the speed of sound in a medium, then you are supersonic.
As an aside, cerenkov radiation is when particles travel faster than the speed of light in a medium - this causes a superluminal shock wave in the medium similar to a supersonic mach cone created by a jet. This page touches on both supersonic and cerenkov radiation quite nicely.
RF does the trick too. A 5-watt transmitter lights a 40 watt tube up with a pretty nice effect.
At a mine I used to work at, a couple of electricians taped a few fluorescent tubes around their 4wd transmitter aerial (in a triangle shape looking from the end of the tube, with the radiating element in the middle). They spent a pleasant evening freaking out all the operators by sneaking around in the middle distance with their lights off and calling up people (with said radio) saying, "Hey! didja see that over there? UFO!?"
Of course, "small" being defined as larger than a few hundred tons. For reference: 250kg objects (44 gallon drum-sized) can create a 50-100m wide crater if they impact dirt at 15km/sec. Lower-orbit velocities are in the order of 7-8km/second and you'd lose a fair proportion of that speed dropping a large (albeit heavy) object through 100km of atmosphere.
And how are you going to lift all that tons of rock? There's not that many rocks conveniently floating about in nearby orbits.
What's keeping someone who knows you well from getting a credit card under your name?
I don't know about you, but in australia, it's called "100 points of ID"
From some random.au website:
Please note that your current licence/registration issued by this Office is not sufficient as proof of your identity. You will still need to produce documents that add up to 100 points or more.
Group A Each document is worth 70 points
* A fully certified birth certificate (or copy certified by a Justice of the Peace)
* A current passport
* An Australian citizenship certificate.
Group B Each document is worth 40 points
(preferably containing a photograph of the applicant)
* A current licence or permit issued under Australian law, eg. Driver's licence
* Identification issued by Government authorities eg. one of the following:
* Public Service employee identification
* Evidence of your entitlement to financial benefits or other entitlements from the Commonwealth or a State or Territory Government
* A student identification card issued by an Australian educational institution
* A statement from your employer or an acceptable referee verifying your identity and certifying that they have known you by your name for at least twelve months. (Preferably with a photograph of you signed by the employer or referee).
Group C Each document is worth 25 points
* Official correspondence addressed to you such as a public utility account (eg. gas, water, electricity), council rates, bank statement or similar
* Bankcard, Visa or other credit card
* Any other document which in the opinion of the person to whom it is produced, provides similar verification of the applicant's identity.

What's worse is phones that allow you to dial the emergency number *through the keylock*, like my nokia 3310. Here's a big hint to mobile manufacturers -
A KEYLOCK SHOULD LOCK THE KEYS!
For example, our emergency number in.au is 000. I have accidently called 000 a few times with the phone keylocked in my pocket. It will happily ignore every other keypress except 0 - 0 - 0 (and 1 - 1 - 2, for you outsiders). What's even more annoying about this particular nokia phone is that when you press a key with it locked , it will *tell* you how to unlock it. "Press Unlock and then *", it displays, and once you press "Unlock", it displays "now press *". Seems pretty easy to follow.
And to top it all off, once you accidently press 000 in your pocket, the only other buttons active are either a small "c" (for cancel) button, or the bloody great big menu key, which helpfully defaults to "send". Guess which one gets pressed the most when it's crammed in a pocket.
Good design, nokia - real good. I'm sure all.au emergency operators thank you.
Perhaps senior-level was an exaggeration there. But on the salarysurveys I've just clicked on, there are perhaps 2 IT jobs that are on par with what I earn, in my "grunt-monkey" job. Good to see that they've gone up, although I suspect you are on the upper side of the bell curve.
I'm unsure of how many IT positions are available in.au these days, but I can quit today and get a job tomorrow at about 4 different places on equivalent pay and conditions. But why quit now, when I only actually work 5 months a year? Gives me more time to play with computers at home:-)
From an Australian point of view: I was considering a career in computers when I finished school in 1990. I decided to become an auto electrician instead. So now what do I do?
- I now work on heavy mining equipment. - It's not a physically demanding job, but it keeps me relatively fit. - I work a roster of 4 12-hour days on and 4 days off. - I get paid 85KAUD (more than twice the average.au wage). - I get six weeks annual leave and a heap of misc perks. - I have a strong (not quite "aggressive" these days) union behind me keeping things safe and sane. - I work on equipment that has computers and electronics out the wazoo, and is (relatively) clean - I get the satisfaction of changing about 20 million dollars worth of equipment from "broken" to "fixed!" status every day. - I get roughly the equivalent of an senior-level IT wage, from a four year apprenticeship that , frankly, any monkey can struggle through. - I can also fix my car at home:-)
Maybe in 10 years time IT will be the big earner again, but by then I'll be a million bucks ahead of that poor post-grad flipping burgers at McD's.
My advice to kids? Stick with the hands on work, keep computers as a sideline.
Is it transmitted "over the air"? yes. So, if I had the technical means (a biiig dish and hypersensitive-OMG-from-teh-FUTURE!!1!! reciever) I could watch every single episode of anything ever broadcast, just by pointing my biiiig dish and hypersensitive reciever at some nearby (~40 lightyear) object and merely record the TV signal that got bounced back off it. Technical issues aside, would I be a pirate? I believe not.
Tell my why this is any different (legally,folks) to bittorrent. They've broadcast it, not narrowcast it. If they don't want people recording their shows, perhaps they should move to a more-private, non-broadcast medium. Good luck with getting an audience though.
Or, if your sufficiently tech'd-up to have a nuke, launch it so that the peak of it's suborbital trajectory is over the US, then detonate.
One nuke in a exo-atmospheric explosion -> All planes bigger then a cessna will drop out of the sky like a bunch of car keys when their avionics fuse.
Oh sure, the military will be fine (if a little bit pissed off). But just about every other circuit above ground's gonna have a whole lot of trouble headed it's way.
You know what? Replace "Catholic Church" with "IBM" and your post is still perfectly relevant!
My guess? One day the entire tech market will collapse out of existence due to a "unfortunate patent incident" and all it's collective IP will suddenly belong to the guy that owns the rights to the Amstrad CPC-64.
"Why yes, as a matter of fact I *do* work next to a large radar facility! How about you print me out 10 of these ID cards so I can just make a once-a-week visit here instead?"
Actually, modern EFI engines turn off the injectors when at zero throttle opening above some RPM level.
My car, turns off the injectors when coasting until engine speed drops to 1500RPM - theres a very faint-but-detectable jolt when they are turned back on. This doesn't hurt your engine because there's no fuel to burn at all compared to a lean mix.
That's a bit harsh. Perhaps you could simply state that "that's not what I experience". Especially since my version (1.0_RC6) told me about 1.03 the other day.
But, perhaps you should look under "Tools -> Options -> Advanced -> Software Update"

Except that copying 850GB is a non-trivial event for just about any connection currently in use.
For example:
850GB, 100Mbit network at 5MB/sec = 47 hours
Time for IT to notice network load pinned and one light on the switch constantly lit.... a day, tops.
Time for everyone else on the network to complain to IT about "slow outlook" = 5 nanoseconds.
Even a raid array delivering to an utra-ata133 backup device on the same system at 50MB/sec... that'd still take 5 hours.
It can very easily be supersonic.
