I would have gave up if I wasn't so busy at work today now I'm in it for nearly 17000 shares!

i need more hash i got 4k shares

I am guessing that it is possible for complete keyspace to search with no valid blocks?  99.98%!!

It doesn't seem like it's just bad luck at Slush - Eligius just finished up a 19 hour block, and EclipseMC is at over 7 hours on their current block.  Even BTCGuild has dropped to an average of 1 block per shift over the last 10 shifts - around 1/2 of what is normal.

block at last! Hurray

[Mikko8]

At last! Congrats to all of us!

11 hrs, 8 mins - Lets hope it does not get orphaned....

Difficulty does look higher to me about 20% at least.

Hi I have a question regarding difference between this pool and bitminter.  I was a big fan of this pool but with the DDOS attack it seems like I've been getting less reward at slush since then.  I have about 300 mhash/s and the way I have to do it is I run it only at night, overnight, so it's like 12-13 hours a day of mining (plus weekends all day).  Bitminter and slush use different scoring systems.  Does anyone know which pool I'm better off at based on my mining times?  Thanks for the advice.

Slush is better for lucky days.  PPS would have been much better on the last block lol

This has been addressed in the thread already.  The difficulty changed right around that same time.  When the difficulty gets harder, your rewards get smaller.

today was not profitable :(my target is 1 bttc a month days like this are painful i must punish the miners no silicon in there gruel today

I keep seeing a lot of people that I think are confused how pooled mining works.
We aren't all doing part of a big problem, and a round is not just one block. Every time the network finds a block the problem changes cause they are all a chain. A share isn't a piece of a puzzle it's a lottery ticket. And we are all pooling our lottery tickets in hope one of us wins with the agreement we all split the proceeds. So this %CDF isn't coverage of a problem space it's just a probability that a winning lottery ticket will be made for the latest link of the chain.
The real trick is that we are all working on low difficulty attempts so we can make lots of them in the hopes that by chance we'll hit one that is above the required difficulty.
Or at least this is what I'm pretty sure is the case usual disclaimer applies I'm not an expert.

Didn't notice however a new card came online the same day and another 1.5 yesterday/today (returned a lesser card).  I was at about 850MH/s during the DDOS attack now approaching 2GH/s.

[jerethdaminer]

in most distributed net processes a big problem 5+5(3-5)x5(19/72+4)  is parceled out to systems
so   bob gets 5+5
joe works on (3-5)
and so on then its put back together

least thats more or less how it works with rccrypt

[jerethdaminer]

so the entire time i was submitting shares, and i still got nothing damn that sucks might have fixed itself stupid miners this requires executions *heads off to kill silicon miners*

[Jcw188]

I understand difficulty changed, I was more interested in the answer to my main question.  Is slush or bitminter's scoring system better for someone who can only mine 13 hours/day.  Thanks.

I will ask again, am I the only one seeing this:

Date: 30.5.2013: Reward 425.26716892714285 BTC
Date: 30.5.2013: Reward 506.74909089 BTC

at mining.bitcoin.cz graphs?

I'm not an expert on the btc protocol per se, but I do understand the mathematics involved, and this is a very good and succinct description for lay people. However, the %CDF is not really a probability, but a measure of how many blocks of this difficulty one would "normally" expect to have been found after this many lottery tickets (shares) have been cast.

EDIT - odd as it may seem, the actually probability that share N finds the block is exactly the same as the probability that share 1 will find it.

Nope, difficulty has been unchanged at 10076292 for a while now - http://blockchain.info/q/getdifficulty - I've got a ticker monitoring it. Just an unlucky round - you get them - be philosophical about it - take the good rounds with the bad and all that...
