Would that really work? To hold 25% of the network hashrate means you're expected to solve one out of every 4 blocks faster than any other miner, but that doesn't mean you can sit on the solution eternally. The point is that on Slush's pool the newest shares have the highest value, so if you can hold it back for 1 minute you would increase the expected payout by several percent. If somebody else solves it first you don't really loose anything unless it's the pool you moved the other miners away from.

The only sustainable way Bitcoin can be live up to its role of being decentralized is if >50% of mining capacity is in the hands of small miners, and pools are what allows this to happen. That's far from petty. Except it's not really decentralised when 50% of the capacity goes away if two IPs are DDOSed.

I updated my post almost immediately with some info. Do you need to know anything else? Parameters are -d 1 -w 128 -f 0 -r 2
Hm. No errors if I add -v. Same thing happens on a 5850 on the same system, although I did get one accepted before it exited when I tried.

You can overvolt if you flash with a different BIOS, but you can't change voltage 'on the fly'.
I wouldn't advice anybody to do this. The reason some cards can't change voltage is often that they use a different voltage controller that doesn't support it. Worst case you may end up bricking your card because the BIOS isn't compatible with it.

The world will never be more perfect than it is right now.
It's a lot better today than it was 50 years ago, so why do you think we have peaked?

If you never see the guy again/deal with him again, is there any rational reason to punish him? There is no guarantee that you would never see him again. Either way it's all about feelings (as estevo tried to explain to you). The minor good feeling I could obtain by receiving a small amount of money would not outweight the bad feeling of letting a greedy person get away with it. If you don't get that bad feeling that's fair enough, but the reason that most people do is that they have the genes that have been the winners in the game of evolution.

An alternative could be to have the client support multiple wallets, and select which ones should be encrypted. Then you could have a "savings account" with most of the funds and strong encryption. Another wallet with just a few btc could be unencryptet so you don't have to type a password every time you make a small transfer.

UPDATE [4/23 3:10P server]: Only 1820 into slush and have 6 stale which is about 0.33%. That is higher than it ever got in my comparisons with deepbit. A larger sample is still needed, but if I were to extrapolate this out, this still comes nowhere near the 1% difference for long polling deepbit claims. Tycho, how did you derive ~1% savings from this?
The number of stale shares has gotten a lot lower on Slush's pool lately, especially if you use a low polling value. It used to be 2-3%, but now I too get less than 1%.
