Don't bother... I have 24 cores and it went up yesterday from 1000 minutes per block to 17000 to 33000 minutes a block last night, if you want to spend 12 to 24 days to gain $2.00's then carry on, if you've got 4 cores, then you'll never gain costs. Ubuntu is the easiest setup, particularly if your using an Apple Mac (just use a virtual machine). Apple Mac OS X setup is continually fraught with problems, and suffers from fragmented and poor instructions, and lack of people to consult who can diagnose the issues that arise. I had the system working a couple of times, but then it would just break for no apparent reason.
i never even got to find one block :(
I arrived too late as well. After much fiddling I finally got my miner working just as rabbit and supercomputer were taking over.
yeah, well I was only the day before! It would have been vaguely worthwhile on my machine, but really wear and tear on computer and increased energy consumption, the amount of time to get it working in the first place... your really just better off buying your coins.
true in a purely short term profit scenario but if everyone had that approach then the hashrate would drop leaving the network open to attack.
If you really believe in a project you should add support wherever you are able to contribute, I myself have supported many coins/projects not for gain but for the simple fact that I wanted them to survive.
on a more positive note i found 2 blocks w00t
