How can I activate the Yubikey on the MtGox website?

You answered the question, avoid PHP if you really want to learn clean programming ;-)

I would start with Python, Java or C++

With PHP/Javascript you learn to write crap code, so don't start with these

When the usage of bitcoin is so easy, that also non-geeks can easily join the party, and not before, I want to see a Big Bang Theory episode about Bitcoin, with their appartement full of mining rigs and a cool story around it ;-)

Why not funding the different projects directly? I think there is no need for a central organisation distributing the money, maybe they don't it distribute it the way the donators wanted.

What happened to the payment for the last days of the original MultiPool? He said he will process it according to the submitted shares in the last backup files... I hope this can be addressed soon

I am mining with BTC guild, used multipool for some time but unfortunately it is down now

The best is to mine AND buy ;-)

I think it would be sufficient if they introduced encryption in the bitcoin client. So a encrypted wallet with a very strong personal PW, with the possibility to move it from the computer onto multiple secured usb sticks should be enough.

I would not solo mine with 500Mh/s, why not using a pool? So you would get a regular income instead of waiting for the BIG BANG which eventually never happens.

Hi, I am Spacy from Italy. I hope I can contribute to the Bitcoin Community

Very good rules!
