MAC addresses ARE recorded by Google Street View vans. They scan wifi as they drive. Have you noticed that your Android phone has location-aware services even with the GPS disabled? Part of that is done based on a fingerprint of wifi networks in your area.
Commercial communications satellites, such as those that operate at geosynchronous orbits, will not use this technology for two reasons:
1. A satellite which fires a thruster for too long for ANY reason is just gone. Once it's spinning, not where it is expected to be, or otherwise unable to communicate with its control center, it's dead. Dead with $300m down the gravity well.
2. A geosynchronous satellite's lifetime is determined by its thruster fuel. The satellite must make periodic corrections to maintain its "stable" position. Engineers carefully order these thruster adjustments every few weeks or months. If the satellite were free to do it itself, every mistake would reduce lifetime and increase the cost of that satellite's radio capacity (which is what pays back the launch investment).
The question is - do you trust the engineers or the software more? I doubt Intelsat will adopt this until it's been tested by someone whose primary motive is not profit.
No, each ISP chooses what routes to accept from what peers. It's called a filter. Smart ISP use routing databases like RIPE to verify what they'll accept and reject automatically. Others do it by hand. Dumb ones accept updates from peers without filtering. It's this last group that needs to update their practices.
When I was in University I got into the habit of always putting my backpack's shoulder strap over one knee or around an ankle when I sat down. That made it virtually impossible to walk away from it, to steal it, or even to unzip it without me feeling the movement.
First, do the math. Calculate the run-time power consumption of your servers. The easiest way is to use real numbers from the existing UPS units, or by using a kill-a-watt.
Second, buy APC UPS units to meet your need. UPSes are rated for the number of actual watt-hours they support. If your servers consume 1500 watts, and you need them to operate for 30 minutes on battery, you'll need at least 750 watt-hours. Considering adding 50% for battery deterioration, and future expansion.
No, I don't work for APC, but they have worked exceedingly well for me and they are supported on practically any operating system you run.
In my network, we have a Linux machine monitor the UPS via USB serial cable using apcupsd, which you can find in your distro's repository. Then all the other machines are linked to that machine also using apcupsd but with an ethernet target instead of USB. When the UPS fails, the others find out within 20 seconds (or whatever your poll time is), and take action. Any data the USB host has, the others have from the network. It is easy to fetch the data via SNMP, graph it in Cacti, etc.
Size - Mars is just smaller than Earth, and even the Earth's core is cooling down.
No large moon - Earth's moon causes tidal forces in both bodies. This causes heat, although the moon's small size allowed its core to cool like Mars. Mars' small moons don't have the same effect and have not always been there (they are likely captured asteroids).
Farther from the Sun - the same tidal forces that a moon would impart, the Sun does as well. But less of it, as Mars is farther away.
My company provides VSAT service in the Middle East and Africa, including as far east as Afghanistan.
VSAT latency is 600-1000 ms, and many VSAT Internet service providers prioritise voice-over-IP. We certainly do, although to a limited number of providers due to technical limitations.
Given sufficient bandwidth, VoIP will do fine. Be sure to use a service that supports good audio compression, and turn it on. Use G.729 or G.723, and never G.711.
On an iDirect VSAT network with cRTP enabled (RTP header compression), a G.729 call needs about 16 kbit each way. Good VSAT service in that area will have at least 64 kbit upload and 256 kbit download.
We didn't forge DoD CAC's. We made official company IDs that looked similar in that they had digital barcodes and chips, but did not in any way forge the DoD logo. They were similar but different. What made them work was that until 2005, the US military didn't have standard acceptance docs for access to many bases, and official-looking company docs were usually sufficient to get on base. It was the professional appearance of the badges that worked - they looked more serious than KBR's own badges.
Social engineering I'm cool with. Actually pissing off the US military I'm not.:)
Large corporations alone are not a problem; it's the way they are doing business that is. Most American companies hired Americans to come work, even manual jobs like driving trucks. The simplest rule of managing insurgency is this: a man that holds a shovel cannot hold a rifle. They are spending far more money now on defense than they would have spent hiring men to dig ditches and other men to fill the same ditches in.
Had that kind of mentality set in at the start - encourage local businesses, keep people busy working (even if on unimportant work), work with locals - the current situation would never have happened. However, it's too late to adopt such a stance and be able to fix the situation. So I can't really advocate that now.
Win? I don't see any definition of "win" that we can achieve. The Iraqi people weren't ready for democracy after 30 years of Ba'ath control, and they certainly aren't now that all the intellectuals, doctors, lawyers, engineers, and other skilled professionals have fled. My greatest hope now is that a powerful dictator will take control, kill half a million people by violently suppressing all dissent, and restore order. If America doesn't have the stomach for that kind of violence, they can't win. Pulling out won't help, but they can't win by staying in with the forces they have.
You didn't hear about us because Ryan was banned from Liberty by base command for some infraction - I still haven't heard the story - and because SSI couldn't penetrate the market without hiring lots of westerners to stay on base. There are ways to get Iraqis on base, but it basically amounts to risking their lives daily, and while we took some risks in my time there, it wasn't worth that one.

That would be an AWESOME place to play Artemis.

Which is why you put the HTTPS work on the load balancer/proxy, and do all internal communication between the proxy and servers via HTTP.

My child gets the actual Lego advent calendar, which is totally secular. So far she's gotten a snowman and a child minifig with sword (!).

Take rsnapshot one step further, and you have BackupPC. Which is what my company uses (mid-level enterprise), and it's awesome.

Indeed. I've done so, and documented it:
http://www.tolaris.com/2010/05/06/moving-an-existing-backuppc-partition-to-lvm/
People smarter than me documented a way to move the data, live, even when the partition is nearly full. See the comments there.

Someone has helpfully compiled Gears for Firefox on Ubuntu 64-bit:

India already has nuclear weapons.

You don't have to change your wireless region, it will likely just work (few use channels 12 and 13 here anyway).
Just get a plug adaptor for your laptop. The power supply for most laptops supports 100-240 VAC, 50-60 Hz. If unsure, read the label on it.
Most London streets have "look left" and "look right" painted on the road at the crossings.
Since when are 1-letter second-level domains allowed? I thought it was limited to two letters and up.
Not true.

Several reasons:
Size - Mars is just smaller than Earth, and even the Earth's core is cooling down.
No large moon - Earth's moon causes tidal forces in both bodies. This causes heat, although the moon's small size allowed its core to cool like Mars. Mars' small moons don't have the same effect and have not always been there (they are likely captured asteroids).
Farther from the Sun - the same tidal forces that a moon would impart, the Sun does as well. But less of it, as Mars is farther away.
This hapenned supposedly when Mars had an active nucleus that generated a magnetic field, protecting the atmosphere from solar winds.
Nowadays liquid water cannot exist on Mars surface, and the bigger mistery is why Mars lost it's magnetic field.
It lost its magnetic field as the core cooled. The fluid movement of a metallic core is what generates Earth's magnetic field.

MOO2 runs just fine in dosbox. The DOS version is considered the better one for network multiplayer, too. Now isn't that frightening?
Actually, SSI did quite well. They changed names and went on, and are still one of the biggest independent ISPs in Iraq. Blue Iraq has nearly folded.
