Govt.s acting arbitrarily against seemingly peaceful activities can get voted out in an awful hurry ... they need a good reason to ban it or else they just look like petty tyrants ... perception is everything.
Let's play the role of the government: "Bitcoin is used to pay for drugs, weapons and child porn" There you go, the government saving the stupid people from themselves, again.

Bitcoin / Mining / Re: MINING IS PROFITABLE

Here is my mining spreadsheet. Assumptions: (PLEASE FEEL FREE TO CHALLENGE): - Value of a BTC will always be related to the cost of power to produce it, since that's directly related to difficulty, which in turn is related to Bitcoin's popularity
It's bull shit. Value of BTC is a term of trust. Nothing more. Mining is a waste of time and cost. [/list] It's bullshit. I got a 5750 back in December for $100, right now I have mined 450BTC. Already had the most of the rig, though.

what exactly does partially solved share mean? you either find a winning-hash (equally to solve a block at difficulty 1) and get a share, or you don't. what kind of partially work is there to take into account?
It takes time to get a share, partially means crunching numbers and not getting it before a block is found. That work is discarded and not taken into account. There's no such thing as a partially completed share... If you're mining at 10 khash/s you're basically playing lottery 10,000 times per second.
That's true mining solo, coop mining you get paid proportionally to your shares.

Other / CPU/GPU Bitcoin mining hardware / Re: Official DiabloMiner Thread

BTW, the java is using 100% CPU in my computer, not 0% as advertised. I want my money back! I'm using the last version. Do you want me to test anything? It should only use 100% CPU for like 15-30 seconds, and then cut down to almost none. Looks like it stays that way, it's been running for a few weeks that way (I can spare a core, heh). It's Arch 64, OpenJDK Runtime Environment (IcedTea6 1.9.3) (ArchLinux-6.b20_1.9.3-1-x86_64), Core 2 Q6600, 8GB RAM, Radeon 5750.

Looks like the pool doesn't take into account partially solved shares. This leads to some inconsistencies (and unfairness), specially when total shares are low, but it's increasingly noticeable as the cluster grows in performance, because there are more chances of not completing a share before the cluster finds a block.
In my case, the cluster has been steadily at around 14-15000mh/s, and I usually get around 0.40BTC per block. On blocks found in a short time this varies a lot: from 0.25BTC to 0.80BTC if I completed a share just after or before, respectively, than most of the miners in the cluster.
I don't know if this is solvable somehow, I use a GPU and the variation tends to even out, but CPU miners are clearly at disadvantage and eventually GPU miners will be affected if the cluster grows large enough.

That's not what I meant.
If I understand correctly, right now, when a client of the cluster computes a block, that block is sent to more clients by the server as a proof of work (that is, to see that they actually compute). If the block is first broadcast into the Bitcoin network (not the cluster clients), a malicious cluster client could recognize the proofs of work. But on the other side, if it's first proof-of-work'd by the clients, then the server could spend seconds, even minutes before all the (connected) clients answer the check. If in that time a block is generated and broadcast in Bitcoin, ours would probably be invalidated (that's what I meant by "steal").
