Comment Lenovo website says they deactivated it... (Score 3, Interesting) 248


"Superfish has completely disabled server side interactions (since January) on all Lenovo products so that the product is no longer active. This disables Superfish for all products in market.
Lenovo stopped preloading the software in January.
We will not preload this software in the future."

However, later in the post they state that the root CA will remain intact. The private key has already been extracted and cracked, so this leaves Lenovo users still open to a very easy MITM attack.

Bad analogy. Apple Pay was accepted everywhere NFC payments were accepted, no additional equipment required. Rite Aid had to turn off ALL NFC payments in order to block Apple Pay, blocking Google Wallet and contact-less credit card payments as well. Apple Pay works within the existing NFC payment system, just like Google Wallet.

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?

Comment Re:Ownership of Spectrum is simply wrong.. (Score 1) 80

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.

Comment Re:FOI request. (Score 3, Informative) 80

It would cost a lot of money to publish every single document that could be requested. Plus, certain documents contain sensitive/personal information, so they may omit certain parts of the document depending on who requests it. You can request the information US Customs has on you. Entries, exits, etc.
