For those who didn't win any BTC trinkets during the last mint race, there's a good deal at Bitmit right now. A BTC/Tux keychain at half price. Offer still valid for over 23 hours as I write this.

https://www.bitmit.net/en/item/16732-bitcoin-tux-opensource-keychain

This is my first time buying at Bitmit. Looks like the site is really taking off, lots of stuff for sale. And, except for someone selling used underwear, it seems to be mostly useful things.

averaging 99.94% efficiency last 3 days.

best rig is 28R per 48000A

also, the 17-second block is shown as 17m not 17s.

With regard to BitMinter and stratum, I would like to ask if anyone else has been seeing a high percentage of rejects from using the BitMinter stratum?

I get something along the lines of 10% rejected due to 'below difficulty' shares. If I go directly to the regular bitminter getwork server it functions fine (no rejects), I also do not get any rejects from Stratum if I go to BTCGuild's stratum server. It's only stratum on BitMinter that has the problem.

This has been happening for a few days now, so it does not appear to be some transient problem.

I am using the 1.3.0 mining_proxy. The proxy and the miners are under Linux. The different mining machines have their own worker account, so I do not believe there's some oddity there, unless the variable difficulty affects all miners under the same user account, which would be incredibly dumb so I hope that's not the case.

The way difficulty changes work under Stratum has changed. You'll see rejects that are below difficulty if you use old software. They typically submit all work, because of the weird way this used to work with Stratum in the olden days. Old cgminer will have rejects, new cgminer will not. Not sure what the status is on stratum proxies.

I changed maximum worker difficulty from 64 to 4096. There are some crazy fast miners around these days.

Let me know if there are any issues.

My mint speed per day went from .49 to .20 BTC from yesterday to today. Is that just because of ASIc or something else going on?

The mint speed shown in BitMinter client is based only on your hashrate and the current difficulty. The difficulty recently went up quite a bit, but not that much. Also, BitMinter client versions prior to 1.3.1 assumed 50 BTC blocks. So if you were running an old version until today, that would explain most of it.

Ahh yes it must have been the block calculation and a bit of difficulty. Thank you for the quick explanation Smiley.

Doc,
A word how you calculate difficulty based on miner speeds will be great:)

let say i have about 100 000 Mhps what difficulty shall i have?

The server watches how often you send in proofs of work, and tries to adjust the difficulty so you send on average 20 proofs of work per minute.

This number (20 per minute) may become adjustable in the future. Will see when I have time for that.

My apologies - Yahoo logins were not working for a little while. Fixed again now.

I upgraded many libraries used by the website to new versions and there was a compatibility issue with Yahoo.

Sorry for the inconvenience.

Now that the 94.7% 8-hour block is out of the way (thanks Keled), let's have twenty <50% blocks in a row.  Who's with me?!

Did you already know that the probability of the former is approximately equal to the probability of the latter? Or was is just a wild guess?

Heh, I see that (vaguely, without doing the math) now that you point it out, but at the time I was just being silly.

Hmm.. I had cgminer 2.10.2 and upgraded to 2.10.5 and still get a lot of rejects (about 9%), although not from 'below difficulty' as an error, just 'rejects'. Running for a day with just the regular getwork server via the nginx/PHP proxy I use and I get nearly zero rejects. I will try again with direct from miner to the stratum proxy and see if it's my nginx/PHP proxy getting in the way. Pity it if is since it's SO useful for pool failovers and configurations and monitoring all miners at once.

Yeah, 9% is ridiculous. Something is wrong there. I guess somewhere in your dual proxy setup things get slowed down a lot. Try connecting cgminer directly to the pool and see how that works.

Poolwide rejects for the current round is 0.16% as I write this. I'd expect some getwork users are above and most Stratum users are below that.

Yea, I had wondered if my setup was confusing things.. Seems like it is. Sad Telling cgminer 2.10.5 to go to stratum+tcp://mint.bitminter.com:3333/ yields zero rejects for the 10 minutes I've been running it. Before I would see the rejects pop up now and then a few times by now. Well, at least I'll have my crap together by the time BFL ships.. lol.
