MY point is Yes there are shares to be had in mining the whole getwork
but most are before 50% and certainly before the last 25% of the getwork
mining every possibility in every getwork doesn't seem to give the most
22 is not a statistically significant sample size in this context.  Observing my miner for about a week, the valid shares found in each getwork seem pretty uniformly distributed through the nonce-space to me.

That's not so say I haven't had a bad hour or two where I run a bunch of empty getworks.  The way the numbers work, you should average almost exactly one share per getwork that is completely searched.  In other words, your efficiency should be close to 100% on average.  I have some days where I'm consistently around 60% and others I'll be at 150%.

And discounting a small sample
makes it invalid Huh
it shows that mining every last part of every get work is useless
if you have a fast cruncher you never see the fallout ... wasted time

cdhowie  you are new and seem to be a troll

last week don't mean Huh to this week
last week was good this week Huh so what
you missed the point
its all LUCK period

how can you base an efficiency on luck
such an efficiency means NOTHING

I did not say invalid, I said statistically insignificant.  You are drawing huge conclusions from a very, very tiny set of sample data.  If I flip an evenly-weighted coin and it comes up heads 20 times out of 25, that doesn't mean that the probability for heads to come up on every flip is 4/5.  It means I got lucky.  (Or unlucky, depending on whether heads is a good thing or not.)  As the number of coin flips approaches infinity, the ratio of flips that resulted in heads to total flips will approach 1/2.  The same principle is at play here.

you missed the point
its all LUCK period
Yup, exactly.

If you are mining solo, you'll know when you have 50 BTC in your wallet out of nowhere.  Smiley

If you are mining in a pool, that information may be tracked.  It is on bitcoinpool and slush's pool; others probably show this data somewhere too.

it will show you in bitcoin client... How many Mh/s do you have? if you are under 2000 Mh/s, it is usually wise to stay in a pool

AMD 5xxx and up
use '-v -w 128' for better performances

This should be "-v -w 128" or "-v -w128" without quote of course?


Also, can enybady tell me what is this?

The number of confirmations of a transaction is exactly how many blocks deep it is in the block chain, with 1 being the current block, 2 being the current block's parent, etc.  The higher the number, the deeper the transaction is embedded in the network's collective history.  A transaction with six confirmations is considered fully confirmed.

The number of connections is simply the number of other Bitcoin nodes you are connected to.  You receive blocks from them, send blocks to them (if you successfully generate one), and send/receive transactions to/from them.

Any one notice
no payout since the last totally 120 confirms

Apparently, FairUser and Geebus temporarily stopped all payouts because the hacker was changing users' payment addresses.

We originally stored everything in plaintext for compatibility with some miners. This was also prior to us adding any account modification tools to the site.

We're working on corrections to the system now to be more secure, and we've since closed the holes that the attacker was using to exploit (essentially hex encoded SQL statements that were overflowing and dumping table data).

We've also tracked the attacker to the russian federation/czech republic.

Our worry was that your wallet ID may have been changed via injection, and that the attacker may have seen your password, which would allow them to log into the account at a later time to change it [your wallet id] by hand.

1) russian federation/czech republic (you know Europe is one big country Smiley , and why not China ?
2) We originally stored everything in plaintext
3) essentially hex encoded SQL statements

I don't want to evolve any kind of conspiration theory, but saying "attacker was from Czech Republic or Russia" has similar weight as "attacker was from USA or Chile, because I know two guys from those countries who may be interested in hurting my little baby". IP ranges, provider companies, language or whatever is completely different in CZ and Russia. Czech Rep was former Soviet union, but it is more than 20 years ago. I'm quite interested in evidence that attacker was from CZ _or_ Russia.

But not too much to register on bitcoinpool forum and ask there (pardon - troll there).

Some people aren't getting paid in certain blocks? I'm definitively stopping mining there! First "malicious attacks" against them and now they don't pay on certain blocks? too fishy for me
