You are correct. When I say they owned the infrastructure end to end, I meant that the postal service is taking responsibility for both accepting and delivering the item in question. On the Net, you simply hand the packets off to your upstream or peer. By the way, Fedex does a huge amount of work for the postal service handling time-critical mail (as well as mail to remote places).
*hopes I'll have enough turbine time soon to fly for Fedex*
Most sites don't do HTTPS for all the traffic because of the performance hit (encryption and decryption overhead). Google can afford to do it because of it's massive amount of computing power.
The postal service owns the entire infrastructure end to end (at least for domestic mail in the US). It's also a quasi-government entity. If I'm a Tier 1 provider (i.e. Level3, Global Crossing, etc), you don't get to call privacy rights on your packets. If it hits my network, I can look at it. Mind you, I don't want to look at your data. I really don't care about your personal info. But if I need to look at packets for some reason for debugging/technical reasons, I don't want to be hampered by legislation. You can either a) Trust that I won't look, or that if I do, I won't care about the payload or b) encrypt every damn packet. I suggest option B. Not because you shouldn't trust me, but because you shouldn't trust anyone.
My old Thinkpad T40 (pre-Lenovo) had no on-board serial, but has on-board bluetooth. I found a cheap serial adapter with bluetooth, works like a champ. Something to keep in mind if you need to move from serial device to serial device often.
When I helped a large organization get data center space, the contract stated that the average temperature couldn't exceed 85F in a 4 hour period (their request, not mine). Something to think about as more and more people are looking for colo space. I'm not saying your contract isn't up to par, as I'm sure it is for the services you're delivering. I'm just saying that customers are becoming more demanding.
Hopefully, if they didn't get the Black Start feature, one of the employees has a large enough vehicle/alternator to jump start them =) I kid of course.
The Bell systems were up all of the time (and had rockstar uptimes) because it was legislated that they had to. Because 911 was being served by them, they had no choice. As the net moves forward, these same requirements aren't being built into systems, and it's going to bite us in the ass someday. Hard.
The FAA is currently trying to replace VORs with GPS-direct routes. Also, with GPS/WAAS, you'll be able to fly Class 3 ILS approaches (basically, zero visibility landings).
Don't forget WAAS. That satellite provides higher accuracy over North America. And locations not covered by WAAS can use local DGPS for additional accuracy.
Actually, civilian radar does ping each plane in the sky. The only thing a transponder does is allow for interrogation of the transponder number by the radar tower.
As someone who owns Google stock, let me explain how they make money:
Ads. If you read their K-1 filing, you'll see that their only real expenses are people, servers, and real estate for people and servers. They make money hand over fist. Check out their cash flow.
This problem isn't restricted to Suns. In the last hosting environment I managed, all of the Cisco gear had to be hard-coded to full duplex/100Mb in the IOS, as auto-detect was busted. All of the Dell networking gear worked like a champ though. Cisco gear is overrated.
So Person B shits themselves when the company sues anyway, right? Because you don't have to be right to sue. You just have to have more money then your opponent.
Communication is done using MILSAT's ultra-high-frequency burst communications I'm assuming. Extremely hard to both jam and detect who is transmitting when the transmitting is done in hostile areas.
With regards to the FCC, I don't believe it to be a felony. Damages can be assessed in the high 5 figures though if you're a licensed broadcaster violating radiated RF guidelines.
As of May 2007, the system is not fully available, however it is maintained and remains partially operational. There were 11 operational satellites in the GLONASS system and one new satellite in its commissioning phase
In recent years, Russia has kept the satellite orbits optimized for navigating in Chechnya, increasing signal coverage there at the cost of degrading coverage in the rest of the world. As of May 2007, GLONASS availability in Russia was 45.3% and average availability for the whole Earth was down to 30.5%, with significant areas of less than 25% availability. Meaning that, at any given time of the day in Russia, there is a 45.3% likelihood that a position fix can be calculated.
In short, that's not exactly what I would call a "global positioning system"
The signal was not degraded because of "terrorists". It was degraded to prevent the use of GPS by an enemy to guide/navigate a rocket-propelled weapon across a continent to a target with precision accuracy. This is also the reason consumer GPS devices have an upper limit on the speed and altitude information they can provide:
Defense department regulations prohibit standard consumer GPS receivers from functioning above 60,000 feet and 999mph (simultaneously). Most GPS receivers seem to set hard limits at EITHER 999mph or 60,000 feet.
However, this is all a moot point. The defense department has the ability to selectively degrade the civilian signal in certain geographic regions, while leaving the military signal as well as the civilian signal outside of that area intact (and accurate).
Someone who is using an ICBM (or some other sort of long-range delivery system) is not going to be using GPS. They're going to be using a combination of radar, topographic map data/recognition systems, and inertial guidance (as to prevent navigation references to be screwed with during the cruise phase of the weapon in question).
I hate to break it to ya, but we've already dumped huge amounts of carbon into the atmosphere that was sequestered for millions of years. Not only do we have to eliminate our CO2 output from fossil fuels, we also need a method to use renewable energy to start pulling that CO2 out of the atmosphere to sequester it again.
But lets be honest, the waiver simply said they could pollute up to the limit permitted by law. Polluting is usually bad, but in the amounts we're talking about for the BP plant, it would be like pissing in the ocean to make it salty.
The problem is the cost to an ISP to have a multi-gigabit core. Hardware for 10GBps cores is obscenely expensive (making the per-port costs high). Until the price of the hardware drops, the price of bandwidth will be held high.

$160 for a pair (so it comes down to $80 per adapater).

In flight terms, we call these terms AGL (above ground level) and MSL (mean sea level). Both are very important to not impacting terrain.
