All I'm saying is... please keep things in perspective. You have legitimate points, but a government that is untrusted by its people (and by all accounts Americans don't trust any existing political party) cannot effect effective governance. In other words, you're asking your government to fail and then whining when they do. That's not very productive.

No, we're asking our representatives to actually represent the people, instead of the special interest. We're also asking that the government follow the constitution and the law, and to stop the illegal programs that break those laws.

I used Dwolla to fund my Mt. Gox account and vis-versa before the shutdown. At first you didn't need any ID, then you needed to upload a copy of your passport/driver's license and also something that verified your address (Bill). Then Dwolla itself started requiring my passport copy. Is there anything else really required?

Accounting is great, however it uses a few tricks that allow costs contributing to a product to be expensed when revenue is made. The most important thing is cash flows, because cash actually adds value to the firm.

The problem with your analysis is that it doesn't take into account the time value of money. A dollar today is worth more than a dollar in a year, simply because putting a dollar in the bank gives you more than a dollar in year. If the present value of the expected future benefits are greater than the present value of expected costs, as long as your cost of capital is correct the project WILL add value to the firm, regardless of how long it takes. this is called NPV analysis.

The payback period method on the other hand is not based on Economic theory, it doesnt take into account cash flows after the payback period, favors small projects and discriminates against large ones. There's no Economic method to calculate a proper payback period, and so the payback periods are arbitrary.

Many businesses have disregarded great projects that would have added value to the firm but simply had the wrong accept/reject criterion. Accounting methods are not quite appropriate here, since the main point of accounting is to match costs with revenues, and indeed the financial formulas to find a stock's price involve taking the accounting financial statements and working backwards to find the real cash flows again.

About perpetuity, imagine that buying the spectrum was equal to receiving a set number of dollarsfrom the government every year, let's say $1000/year forever. Assume a 6% cost of capital for the company. Now we can easily find out how much this is worth today. 1000/.06 = $16,666.67. (This is a limit simplified down, 1000/(1.06) + 1000/(1.06)^2 + 1000/(1.06)^3 + ...)

That would be the cost you need to pay today to get a perpetual annuity of $1000, kind of like buying rights to the spectrum.

Are you still baffled? It's really just Economics backed with maths.

I may be an anomaly, but every single AppleCare warranty I take out, it pays for itself and onwards.
1. Powerbook G4 - Two motherboard replacements, $600
2. Macbook Pro (2005?) - Two motherboard replacements, new Macbook Pro to replace(They let me get AppleCare on this one too, 3 years starts over) - $1000 plus cost of new Macbook Pro
3. Macbook Pro (Early 2008) (Free)- Now has a red line going down the screen...guess I'm getting a new laptop.

I just emailed my airline expressing my concern of the scanners. If enough of their customers start telling them they don't want these, the airlines, who are in a relatively high position of authority to negotiate with the TSA, will try to change policy. People being annoyed, humiliated, and pissed off is not good for business, and the airlines know it will hurt their bottom line.

Also, with VPN, once someone is connected to the VPN, they're another peer, just like a wired peer. I fail to see how you get any benefit to your proposed solution to the problem.

The benefit of the VPN is that it encrypts your traffic so that someone using this exploit wouldn't be able to see and manipulate your traffic.
