Science is NOT absolute. Mathematics... yes, within itself :-)

I think 1 BTC = $1000, or 350 pounds of dreams, or an ounce of love 
And guess what: my guess is as good as yours 

In order to avoid my opinion and your monopolizing the market, we have MtGox 

How many apples for a cow? What about oranges? How many bitcoins for another day to live?
Jeez, I'm getting poetic, philosophical and... subjective?

if you are serious about getting into bitcoin trading, stop using paypal for your bitcoin-related payments. paypal transactions are reversible, bitcoin transactions are not. I am sure you can see the problem here...

Human factor and buggy software explains 99% of all issues...

Cool graphs Wuked. Thanks!

A trustworthy exchange should have all transactions made public in a way that allows for completeness and privacy:
1. completeness: all buy/sell orders (not just executed trades!) should be available to the public for examination;
2. privacy: examination should not reveal particulars/identities etc.

Hard to accomplish without a third-party trusted auditor...

What a wonderfully complex question! Tomes have been written, with no clear answer... The only absolute truth is that everything is relative 

Bitcoin is PERFECT for micropayments. Can we persuade NYTimes (or some other major newspaper who is willing to increase revenue) to accept bitcoins for access?

Great idea it is, simple it is not, young Skywalker... Good luck and keep us posted!

I am reporting on two transactions with BitcoinExchange.cc

Transaction 1: Bitcoin -> Liberty Reserve. It was almost real-time, although over email. I sent the bitcoins and got the LR in my account in less than 2 minutes. Impressive!
Transaction 2: Bitcoin -> GreenDot MoneyPak. It took a few days due to some issues BitcoinExchange had with PayPal (why am I not surprised?). The problem was clearly explained to me, and all my emails were answered in a timely manner. I just received the MoneyPack codes and deposited them with no problems to my GreenDot card account.

A note on Transaction 2 is in order here. When I sold my BTC to BitcoinEchange, the MtGox exchange rate was much better than it is now (to my advantage). BitcoinExchange did NOT change the terms of our deal, which I really appreciated! 

Thank you BitcoinExchange, and keep up the good work!

If you have enough power, proper cooling and a decent motherboard the number of cards should not affect their performance. If power is insufficient, you can use multiple PSUs.

any luck yet?

Nobody can shut down all the miners and all the users. That's the power of bitcoin!

Sort of  But it also eliminates the single point of failure that such a centralized server would be.

What about a laptop next to the veggies? 

Very interesting idea! Any prototypes?

Did you ask Technocash?

I would have no problem staying at a hotel that accept bitcoins 

Mining with your current configuration is a waste of electricity. Unless you are extremely lucky, it may take years before you solve a block and get 50 BTC. Joining a pool may help you get a few fractions of a bitcoin to play with, but no more than that. Mining is pointless these days unless you can afford some pretty expensive hardware. Just buy some bitcoins with the electricity money
