I have seen two older animations done by justmoon's designer and have to say it looks really professionally.

Wait untill tomorrow, please

(I simply cannot stay outside)

Yes, less load on server for +/- same total pool hashrate. But you (as a miner) are not motivated to have huge hashrate on server, you're motivated to have high OWN hashrate. Higher pool hash rate does not make your payouts higher (only more steady). So with long ask rate to server, you're cutting your effective hashrate and losing some valid shares because you work on stale jobs.

I'd like to notice that they are doing it more effective for them (for the pool), but using this "hacked" miner is less effective for users. We had long discussion with FairUser and Geebus about this and it looks they still don't understand what they are doing. Pretty bad for pool operators . Their "mining efficiency" is absolutely irrelevant number.

I'm not using "ineffective miners" on my pool because I'm masochist but because it is good for users. By the way, everybody on my pool (or every other current pool) can "optimize" his miner by setting custom ask rate on command line. But I really don't recommend that.

Because I don't like to start long discussion about nothing again, this is both my first and last post in this thread. Thank you for reading.

OK, it was very easy, graph is fixed.

I did small mistake during update yesterday, I'll fix it today.

0E-8 is (not clear) notation of zero, your reward from this block is probably such small that it is rounded to zero (on 8 decimal place). It can happen when you submitted share on the beginning on such long round.

Yes, that means your worker found real, full difficulty bitcoin block. Congratz!

Those numbers are fine (calculated from shares in current round), but I tried to avoid never ending questions "my miner reports 300 Mhash/s, why page show more/less"? People who know can check hashrate in sources.

Simple math gives me that 5 < 8. So yes, 32bit system works for you. But 4x5970 does not work. Trust me .

hehe, can you explain it a bit, please?

Pick one of mode and don't switch after few lucky/unlucky rounds. People should stop thinking about one round; this is probability, gentlemen.

I bet that many people switching between two modes frequently will make less than with one of them all the time, because:

a) When they see few lucky rounds and switch to share based, pool will have long rounds then and
b) When they see few long rounds and switch to PPS, pool will have few very short rounds, because

BUT IN AVERAGE, IT IS STILL THE SAME

One round does not depend on another. Depends on your personality, pick one of mode and keep them; it's the best what you can do.

I added sipa's graphs to wiki page about difficulty.

I don't recommend using Ubuntu for many GPUs at all. I've been using Ubuntu, but had troubles with third card in my setup. Reinstall to Squeeze helped.

As there are many users reporting troubles with Ubuntu & GPUs, I think there is something broken inside.

Edit: I found the trouble: don't use 32bit Ubuntu (or whatever else 32bit distro)! ATI drivers allocate 256 MB of virtual memory for every core, so setup with 8 cores ate whole 32bit memory space. 64bit installation should work fine (I didn't tested it yet). Thanks ArtForz for investigation.

Yes, and that's the point. First typical question of newcomer is "where I can buy/sell small amount of BTC for test?". So service like coinpal/coincard is very important in the first impression. Two people said me "Are you kidding, this?" when I pointed them to the coinpal .

As I wish to Bitcoin to be successfull and go to mainstream, I really care about those 'little things', because they SELL. But once again, mndrix is doing great job.

Sorry for offtopic, but are you Czech/Slovak or is your nickname just a coincidence like this facebook profile? :-)

Same error on withdrawal here...

Mining is process of validating transactions between users, performing some special algorithm described in Bitcoin.pdf above. Technical background is quite difficult, but basically Bitcoin network need as much computation power as possible for doing this task, to protect network against many types of attack.

Miner is specialized software searching for unconfirmed transactions on network and include them to the algorithm which it performs. Once the miner finish his task by finding specially formated data, also called as "proof of work", and push this data (called "block") back into the Bitcoin network, the transaction included inside this block become confirmed ("1 confirmation" in Bitcoin client).

As incentive to attach own computer into the grid and start mininig software on it, miner can take 50 BTC for every valid block he found for the network. It is done by special transaction included into the block itself. This is the reason why there is such hype about mining around, because those 50 BTC was pretty easy to earn and when Bitcoin reached the parity, it become very profitable.

But Bitcoin network has many self-regulating algorithms included. Namely it is "difficulty", which regulate number of blocks mined every day. Bitcoin network is trying to find 144 blocks (=7200 BTC in miner rewards) ever day, without care how many people is mining. So as the network grows, it become harder and harder to find valid block for every participant. I'm talking it because I feel people are too much oriented about mining, but this is just technical solution how to kick up the economy and spread Bitcoins between people. Mining is NOT a target, so if you don't have strong mining rig, nevermind! As common Bitcoin user or newcomer, you don't need to understand whole stuff around mining and you don't need to care about mining at all; you can sell goods, provide services or whatever and earn much more Bitcoins than by setting up Yet Another Mining Rig (tm).

Thanks a lot .

There IS testnet network. Just start bitcoin client with -testnet argument.

Thanks, I have that on my TODO already, but keem them for self and send them after the feature will be online :-). I don't want to feel commited right now .
