My apologies if you have already covered the subject, but ... what are your commits on the use of mining_proxy with the new ASIC boxes coming online?

And does anyone know if bfgminer supports the variable difficulty being talked about here?

Yes, for the past several versions. Your worker hashrate needs to be high enough, though. Roughly 20 shares/minute is the threshold I believe. I have a 1.6Ghps worker (~22 shares/minute) which never sees a difficulty higher than 1. A 12Ghps worker would see a difficulty of 8.

We have one bfgminer setup with 24Ghps total, so I'm assuming we should see the difficulty rising.  What this quickest way for me to check on that, and is the difficulty level something I can set myself?

Thanks for your feedback...

To check, just connect your miner to the pool (-o http://mint.bitminter.com:8332 -u <user> -p <password>) and wait; whether you use stratum or not doesn't matter. It will start at difficulty 1 but in a short while (a minute or two) you will see the difficulty increase as the pool gets a better idea of your miner's speed. BFGMiner displays the target difficulty in real time as shares are submitted, so once you see that number change from '1', you know vardiff is working for you.

Something like this (the 'Diff 32/8' means that the target difficulty is 8 and the submitted share had a difficulty of 32):

Code:
[2013-02-24 21:19:11] Accepted 08e39d0a BFL69  pool 0 Diff 32/8

In your case with a  speed of 24Ghps you may see a difficulty of 16. As for setting this yourself, no, currently that is not possible at BitMinter. It is automatically adjusted by the pool based on your hashrate.

My recommendation is to not use proxies unless you actually need them. Bfgminer has Stratum and vardiff support built in, so you'd be better off connecting it directly to the pool. But  if you have multiple mining computers on a local network, you may save a little bandwidth by using a Stratum proxy instead of having each connect to the pool directly.

How does the pool take into account the miner's higher difficulty set point that would correlate to a lower submitted hash rate and the payout share?

It pretends like one proof of work mined at difficulty 32 is 32 proofs of work at difficulty 1. So the payout is fair, but there is a little more variance at higher difficulty. As far as I know this is how all the pools handle variable difficulty.

If you want to know more about that I'd suggest you check out organofcorti's blogpost about it: http://organofcorti.blogspot.com/2012/10/71-variable-pool-difficulty.html

The OpenID identity provider myid.net appears to have shut down. If you can't get into your BitMinter account because of this, contact me at operator@bitminter.com

question about walletbit.com

Haven't seen that one. An online wallet? I hope it's temporary.

yeah they are an usa online wallet company.

 I just converted all my coins (7) last night from wallet.bit to fastcash to paypal. I have always held coins less then a week. So it is not like I have a lot of coins in the wallet. So if they have a big problem I am lucky in that I have under .5 coins in the account.

   My method is earn 4 to 8 coins then cash them into paypal or an amazon gift card.

Is this a temporary issue or shutdown permanently?

If you go to myid.net it redirects you to another site which displays a message in korean. It's an image so you can't paste it into google translate. But one miner told me that myid.net have shut down permanently.

it is back up.


https://walletbit.com/   


 one of the reasons I always sell my coins is fear of storage.. i have earned 250 plus coins but never held more then 10 or 12 at a time.

 On one hand I would have liked holding them all, but  on my other hand if I had 250 plus coins in walletbit for the 20 plus hours it was down I would freak.

i've never kept more than 5 bitcoins just because i've always sold them as i went

but if I intended to keep a sizeable amount, i wouldnt use any online wallets, i'd just store mine on a usb flashdrive (and make a backup on a 2nd usb flashdrive), removed from computer when not transferring coins

Dacentec, best deals for US dedicated servers. They regularly restock $20-$25 Opterons with 8-16GB RAM & 2x1-2TB HDD's (ofc, usually lots of other good stuff to choose from).  I did a Serverbear benchmark of one of my $20/mo Opteron (June last year), it's here.  Have had about a half dozen different servers with Dacentec, & none have failed to sustain at least 40MB/s (burst higher). My favorite is a 12-month rent-to-own ZT Systems 2XL5520 16GB 2x2TB SATA for $40/month (got lucky with the 'off-brand', haven't seen a RTO 2xL5520 for under $50/mo since -- at least for monthly contracts).  wholesaleinternet.com has some ancient 2-core intel CPUs @ $10/mo sometimes (I got an Intel Core 2 6300 @ 1.86GHz, with a 250GB HDD with 46000 hours on it, LOL. $20 @ Dacentec is much better, if you can grab one). joesdatacenter.com (same location as Wholesale Internet) also occasionally has specials (or if you don't want to wait, it has an AMD Opteron 170 @ $16/mo).

I don't think the problem was with bitminter.  A HUGE number of websites just became unaccessible recently.  A few people in my chat (in different countries/continents) were having the same issue loading a significant number of websites (including sites like ozcoin, blockchain.info, bitfunder, and even imgur).

Dude,
The site is OK and server also DNS is broken which means that after some time usaly up to 8 hours you will be not able to resolve the site ip and it will look like site never existed.  I do not know about other sites mentioned:)

CloudFlare is dead in the water. Unfortunately we use them for DNS, so you can't look up any bitminter.com hostnames right now.

Some miners are still at the pool mining. You can use 176.9.104.178 instead of mint.bitminter.com and keep mining. But remember to change it back once things are in order again, otherwise things won't work the next time the mining server moves.

I hope CloudFlare will get their systems up shortly.

Apologies for the inconvenience.
