We're still not that large, but I have started posting notice that BTC Guild's first phase of 51% mitigation will likely kick in soon (PPS fee increased) to try to encourage users to move to other pools.  We're at 39% of the last 2016 blocks, and the fee increase kicks in at 40%.

Hey Eleuthria - fancy meeting you here!   Hang out on Slush much, do you?

Hey Eleuthria - fancy meeting you here!   Hang out on Slush much, do you?    

I lurk most the pool threads, I like to know what's going on, and sometimes post some advice/corrections whenever possible (Stratum proxy issues, people assuming luck is statistically impossible even when its completely within expectation, etc.) .  Pool ops aren't constantly waging war against each other as some would like to imagine .

[rsbriggs]

I like mining on BTC - but it's not my little 184Mh/s that's making much the difference...   

Looks things grew about 5 Th/s the last week.  I wonder if batch 2 Avalons are in delivery and they all hooked up there.

[rsbriggs]

Wow, BTC Guild hashing at 53% of network -- let's hope their admins are honest  

Why not ask him?  That would be Eleuthria - see just above message.

is gox ok to use to get cash from coins?

I prefer coinbase, I have my reward sent straight to them, and every now and then (depending on gox's price) sell straight to my bank account.  They do a 1% fee, and there's like a $0.15 "bank fee".  Way cheaper than gox if you are cashing in in the single digit BTC or less.  Now, gox's $10 wire transfer fee is looking okay around the >$1000 worth, but...not for this small fry

Did anyone notice that slush's pool lost a lot of luck finding bitcoins today?

Pool luck (1 day, 7 days, 30 days):   53%, 94%, 99%

is this normal or this means that a lot more people started mining and the difficulty increased?

1-day luck can see pretty bad swings.  All it takes is one block at 7-10x difficulty to completely kill the luck for an entire day.  30-day is the number that would indicate problems, and 99% doesn't look like a problem to me .

Just swapped out 3 GTX 480s for Asus 7850s.  Using guiminer, doesn't matter which of the cards I start first and it puts out 333 MH/s, but the other 2 only put out 2-3 MH/s each after start.  So, what miner do you guys suggest I use, and what should the command line or config file to run all 3 7850's at full bore?

It's been a long day and night on Slush's pool.  We had an 11 hour round... one of the longer rounds I remember.  Now we're back on another dry streak...  I happened to noticed that you guys were finding a good majority of the blocks and checked the blockchain hashrate and you guys are at 51 percent.

Ugh.

I'm glad to see you have some plan in place, but what about disabling new account creation temporarily?

All in all, these long rounds make up for the 30 second consecutive block rounds we've seen in the past few days, so it all smooths out mathematically in the long run.  It was interesting to see you with 51 percent of the blockchain hashrate.  Not really great news for the BTC community/market.

I've finally reached my first payment's minimum threshold. THANKS to those who helped me get there. It would have taken me months without you. I am definately going to take a big holiday from mining now

We're all in it together.  Keep mining... it'll only get more difficult.  Every day you don't mine is lost forever and hashrates and difficulty will soar..

keep mining!

Try cgminer.
All instructions and info can be found in that thread.

Ok, think I understand cgminer a bit better, but can't get it to connect to stratum.bitcoin.cz:3333, says "no live pool" and gpus do not start.

My command line is:
cgminer -o stratum.bitcoin.cz:3333 -u [my worker id] -p {my worker wd] --shaders 1024 --intensity 17,17,17 --worksize 256,256,256 -g 1

I tried the same command line except with --scrypt flag and connection to LTC pool, all gpus fired up and pumping 275 KH/s each.

try once with just --intensity

btw: 17 sounds very high when not --scrypt from my short experience. (not that you said what cards you have. )

I'm running three Asus HD7870DC2-2GD5-V2 gpus
tried your suggestion with command line = cgminer -o stratum.bitcoin.cz:3333 -u [my worker id] -p [my worker pwd] --intensity 10

cgminer returns the following:

probing for an alive pool
pool 0 JSON stratum auth failed: (null)
No servers were found that could be used to get work from.
Please check the details from the list below of the servers you have input
Most likely you have input the wrong URL, forgotten to add a port, or have not set up workers
Pool: 0 URL: http://stratum.bitcoin.cz:3333  User [it's showing the right worker id]  Password: [it's showing the right pwd]
Press any key to exit, or cgminer will try again in 15s.

guiminer connects to stratum.bitcoin.cz:3333 ok, but it can start all 3 gpus, only 1 does any work.

well, enough for tonight -- gotta get some sleep

It is trying to connect via the old getwork protocol over http. try:
cgminer -o stratum+tcp://stratum.bitcoin.cz:3333 -u [my worker id] -p {my worker wd]  --intensity 9

For bitcoins intensities above 9 does almost nothing. but you can experiment.
(Well if you have gpu sync enabled max is 14 without 10 is max.) But did not do anything for me except destabilize my system

You should check out Bitminter's - https://bitminter.com/blocks

From the last 20 blocks they had only 6 that took less than an hour. Almost all of the rest were around 2hrs, 5 of which exceeded 3hrs - they had a 4h:43min, 6h:18min and 7h:28min in a span of just over 24hrs!

And they're not way too low on hashrate either - around 6.5TH/s.

So nothing to complain really... It's just luck ... or rather lack of.
