Hello,
I've been out of touch for a while. Anyway, I have a new computer with a fancy 4 core CPU and I would like to get into the mining business again.
So my question is, what's the best CPU miner? Assuming that it's going to be used in Slush's pool.

I should mention, I'm using Ubuntu 12.04.

(I'm just going to be experimenting at this stage, to see if the economics are worth it. I'll see what I can generate over a month, and compare against electricity usage. If it doesn't work out, obviously I'll quit it.)

Thanks.

Anyway, I've got about 500khash/s on my little old laptop. I realise that the chances of me finding a block are probably basically zero. The question is, does it help or hurt the network having me generate? Or is it pointless?

I don't mind, the 'lectricity is free for me. (Not interested in getting another computer, or anything, I'm only staying here a couple more months at the most.)

edit: shit all sold. no more shit 4 salez!
