If you're in the piney parts of southeast Texas (Beaumont, Houston, Jasper, Vidor), you'll discover something interesting about 800Mhz. A pine needle is almost the same length as an 800Mhz radio wave and thus they make great RF absorbers. Get into a good dense grove of pine trees and you'll not be able to hear shit.
The folks where I used to live in the Texas hill country got a big hardon once for an 800Mhz trunked system until they discovered they'd have to put in 20ish separate repeater sites to cover the county.
Instead they invested their drug bust money in a system that you could hear all the way down to Corpus Christi but couldn't talk back into from 20 miles away without a 100W mobile.
It'll never make it through FDA trials

Of course they did. If you cure cancer with one shot, the cash cow of chemo drugs dries up for Big Pharma and the cash cow of donations dries up for the American Cancer Society and other 'non-profit' organization.
The county I grew up in went with this thinking. They scored about $350K in a drug bust and used that to buy a high powered (transmitter output was 350W) Motorola 150Mhz encrypted radio system. The transmitter was located in the Texas hill country northwest of San Antonio and you could hear it down in Corpus Christi, but you had to have a 100W mobile to be able to talk back into it from about 20 miles from the transmitter. As a comparison, my father and I put a 75W Amateur Radio 145Mhz repeater system with cheaper equipment and smaller antennas and could cover the entire eastern half of the county with a 5W hand-held.
Then they had to shitcan the whole encryption system about 5 years later when the radios started dying and they couldn't afford to buy new encryption-capable Motorola radios. The guy in charge of the county radio system was a Tait dealer, and oddly enough the county started buying Tait radios.
Better than the technical wizardry of my previous employer.
The main authentication server fell over one morning (as it did once a week due to heat in the server closet). Engineer called and said it had fallen over. I said "Okay, just go reset it. It'll live over it". Engineer couldn't find the reset button, so he just unplugged the rack.
In that rack was the file server, auth server, Asterisk server, and a personal server of mine. It took 4 hours to recover from that.
Why was there a heat issue in the server closet? Because I was not allowed to put those servers in the data center because management felt they needed to be closer to the end users for performance. Nevermind the fact the office and datacenter were 60 yards apart and tied together with GigE.
If you can *get* them into space without the treehuggers freaking out over "What if the whole thing explodes on the pad and scatters radioactive material across the entire country".
So when you access that app, it logs that you accessed that app, which logs that that app accessed the app data, which logs that the app accessed the app data showing that it accessed the app data...
I can't find the plans directly online for the turnstile antenna I have, but here's an antenna that actually works a bit better, and probably costs about the same to build:
For the radio, I use a Radio Shack PRO-433 scanner I picked up a pawn shop for $50. It doesn't have the IF bandwidth to create perfect images, so I'll eventually upgrade that to an ICOM IC-100.
For the software, I use a package a friend of mine and I wrote running on a NetBSD server, but there are other packages for Linux and Windows:
If Big Weather (The Weather Channel, Intellicast, Accuweather, and a few others) start putting money into the system you know damn well that their first requirement will be to lockout anyone else.
Accuweather tried that one a few years back by buying Rick Santorum and getting him to start legislation (see S. 786) that prohibited the NWS from providing forecasts/data/whatnot to the public if a private corporation (*cough*Accuweather*cough*) could do it instead.
Bullshit. You can receive APT images from the NOAA-N series of using a $20 homebrew turnstile antenna, a radio scanner, and a Windows/Linux box with a soundcard.
I never locked my iphone until I accidentally left it somewhere. Fortunately, it was there when I got there but I'd have been boned if someone picked it up and did nefarious things with it before I could reset passwords/passcodes.
Now it's set to lock after 5 minutes of non-use and to nuke itself after 10 bad passcodes.
That'll work well. I know I was ready to return my PS3 to Sony accompanied by select choices from my cat's litterbox if they didn't get their shit fixed soon. I wonder how many ps3s wound up at a pawn shop to finance the purchase of an Xbox.
I have a Comcast business line at home and have the same problem. The SMC modem/router that you get is a festering pile of shit. Doesn't support v6 at all and needs to be rebooted at least once a week. My "core" Cisco router has a DOCSIS 2 port on it, but Comcast says that I can't use it on their business class line.
Except the ol' Clarke belt is getting damn crowded these days. You can't just launch a shit load of satellites up there and then expect an 18" DBS dish to be able to tell them apart.
Is there anything more? Other than developers needing dev tools, I'd say that probably 80% of the office mice in the world need a web browser, an office suite, and an email client.
I worked in the IT department for a company, and we ordered a couple of laptops for evaluation from CDW. One of the laptops was defective (the lid closure switch didn't work). So I sent it back and got a replacement. A week later, we ordered a dozen laptops. In that shipment was the defective one I had sent back, still in the same box I shipped back in (I had torn the box trying to get the box open). Needless to say, a nasty phone call was made to our sales rep and he overnighted a replacement and they never asked for the defective unit back. I kept the defective unit as my desktop.
I had an extra 4GB of free memory I wasn't using. FF4 will expand to fill that quite nicely. Sorta like expanding foam plugging up leaks. I wouldn't want any information leaking out.

Uh, no. When I deliver VOIP calls to my termination provider, they get no ANI from me. They just get whatever CID I set in my SIP headers.
So when you access that app, it logs that you accessed that app, which logs that that app accessed the app data, which logs that the app accessed the app data showing that it accessed the app data...
What about the termination only providers who don't "issue phone numbers" to customers?

You can also pick up a copy of the Weather Satellite Handbook from ARRL for some other goodies.

I think I have $125 invested in my system here.

And no, I don't use the same PIN on my ATM card.
That's not "completely separate domain". That's "same domain with some sandboxing".
There's still the chance of some prick tossing sand in from the other box.
That'll work well. I know I was ready to return my PS3 to Sony accompanied by select choices from my cat's litterbox if they didn't get their shit fixed soon. I wonder how many ps3s wound up at a pawn shop to finance the purchase of an Xbox.
I'm expecting the installer to be nothing but a Rick Roll on DVD.

Then they'll be happy to sell you the "twice as expensive per month" business class so you can still connect to "the cloud".
That won't work for "Instant Gratification America". If I want to watch a movie, I want it now. Not tomorrow. Not a few hours from now.

I use it all the time talking out a serial port. Minicom blows dog.

I'm running 3.6.15 extensionless and quite often it balloons up to 1.5GB RSIZE with 7 or 8 tabs open. So, I'll crawl back under the bridge now.
