You cannot detect someone snooping on your wireless traffic. You don't know if they've been at it for an hour or a month and you certainly can't rely on the attacker only getting a few packets. And definitely not by assuming the volume of packets you can get from a weak signal.
If your encryption can be cracked in a reasonable length of time, you have to assume it will be cracked and account for it.
Security is a binray condition, you are either secure or you're not. If you aren't you can choose your level of risk and you have accepted a higher level of risk than I would be willing to subject myself to.
Again, no. There's security but it's as in false-sense-of.
You can't assume how far your signal can be detected. If you're counting on distance to help protect your signal, unless it's a veeeery long distance without physical access, you are deluding yourself. What if someone is listening with very sensitive equipment? What if a firmware upgrade increases the output power of your gear? What if it's the office in the floor above you doing the evesdropping? There are a lot of what-ifs.
If you're thinking about signal strength in the same breath as security you have a lot to learn about what it means to be secure.
Step 2: Make your online music service the de facto standard so record companies will reduce your cost to a reasonable level.
Step 3: Profit
Right now Apple is paying way too much per song. It's probably the concession they had to accept in order to sell the music online. However once iTMS becomes The Place to Go for Music, if it isn't already, Apple will no longer have to accept such crazy prices. When that happens the service will be making a profit, and probably a healthy one at at that.
It's a fact of life that until all of the organizations agree to "go digital" any maps from government will be suspect and at least partially crap. The problem is that NavTech isn't doing a patch job when they should be pushing to fix the real problem, crap data from public sources.
NavTech doing it themselves doesn't guarantee accurate and up-to-date data, only that it was acccurate at the time the drive-by was done. In three months the road they just drove down could be permanently blocked off, turned into a one-way, have a flood, etc. So they're just fixing up the data just enough to be useful for now. Imagine three years into the future when they get a new map from a municipality and there's conflicting data. Do they use the data from the municipality or their own, older, survey? It's a no-win situation that can't survive in the long haul without an incredible amount of investment.
Instead they should be fixing the absolutely critical issues and spending the rest getting everybody to do the work for them. Look up any laws about accuracy of government supplied geographic data (I believe municipalities MUST have accurate property lines, and the FAA MUST have accurate airports, etc.) and make sure they're enforced. Fund an "innacruate data cost the taxpayer money" campains. Set up a feedback system where people can flag innacurate areas so NavTech can fix the data, then tell the source of the data about the problem. Go after sellers of completely bogus data with threats of minor lawsuits for providing an unusable product. Coordinate with other spatial data organizations under one umbrella for more leverage with the data vendors. Work to pass a law or agency requirement that basic well-formed spatial data be provided about transportation infrastructure. Get ahold of DARPA and convince them accurate street data is required for their autonomous vehicle project.
There is a huge list of things they should be doing to save themselves a massive amount of work in the future. While they still have to GPS the critical areas right now, if they are too short-sighted they'll find themselves doing it for decades.
Very close to every road is already digitized in the computers of municipalities, fedral and other government agencies. What we need isn't a swarm of GSP receivers but get the information into once place and make it public. The information already exists in pieces and it needs to be coordinated and released.
I wanted to shoot a solar flare into the Sun after it started going BEEP BEEP BEEP BEEP BEEP after I cat(1)'d my paper to the console. All those CTRL-Gs in the file made the machine completely unresponsive and beep incesently. After 15 minutes I just couldn't take it any more.
Annoyed as hell and not wanting to take down the machine the hard way I did what every network admin fears a user will do; I found a screw driver. With pleasure and resourcefulness I opened the case and cut the wires to the speaker. That'll fix it I though! Except it didn't.
I learned something that day. Sun machines beep using a buzzer in the keyboard.
Brute force is allowing certain types of problems to be solved trivial, freeing up mathematical minds to concentrate on other problems. There is no shortage of problems for us to be clever about.
ARRRGGGG. I hate mis-typing the closing I tag. The first paragraph is a quote, the last two are mine. It should read like:
The problem I have with stories like this is that the calls aren't really free. You do have to have a rather high-speed internet connection to make these calls with any reasonable quality and reliability, and you have to pay that fee on top of your existing phone charges.
If I could use VoIP for all of my calls it would be better than free, it would save me having to pay $35 a month for a phone line. Why does everybody forget a lot of us have existing broadband that could be used to do VoIP for no extra charge?
Let's say worst cast someone dumps their landline and gets broadband to only do VoIP. With a very moderate amount of long distance calls they'll still save money.

Yes, it costs something extra in electricity with modern processors. There are two ways to approach this for people who think the extra couple of bucks isn't worth the science:
1. Turn off the outside light you leave on 24 hours a day instead and you'll still end up with a 15 watt savings.
2. Set the computer to sleep, hibernate or shut down when you haven't used it for a while. While boring the processor to death surfing the web the machine will consuming it's normal amount of power anyway (for the most part). You might as well use the extra clock cycles for science.
3. Take the 420 cans of Coke and Dr. Pepper under your couch to the bottle dept to cover the extra cost of electricity.

100 years of aviation and we get air travel very safely at unbelievable speeds, where going through the airport often takes longer than the flight itself. It's become so routine nobody even thinks of how amazing flying is.
100 years of aviation and we get safe, affordable high performance airplanes that you can buy and build yourself.
100 years of aviation and we get piston engine airplanes with greater than 1:1 thurst to weight ratio.
100 years of aviation and we feel confident enough to land airplanes without being able to see the ground.
100 years of aviation and we find the next 100 years is decided by laywers and the insurance industry.
I have an amazing mechanism to do all of these things, for which I hold 41 patents which I enforce vigorously. It's a process I call a "Have a Child or Borrow Someone Elses".

No, it's not.
Why would it matter? Because the bad guys hate to drive? Because you're counting on nobody really bad living on the same block as you?
Again, no. There's security but it's as in false-sense-of.

You don't want much more power, not only for security reasons but for frequency reuse!
Power level has nothing to do with security.

I, for one, look forward to playing Stephen Hawking in Unreal Tournament 2004.
Even without control of his legs he would kick your ass.
He has a PhD in pain and a Masters in diaster, the mighty Stephen Hawking is a Quake Master.
