I've had to institute a minimum of 1 coin to cash out (all currencies).
We are getting killed by LTC transaction fees (down 30 LTC as of this post).

The profit calculation on multipool.com is different from coinchoose.com and from coinwarz.com. Why? How can I be sure that I am always mining the most profitable coin, if there are different calculation results?
Those sites don't account for stales and such due to fast block times. Multipool does. If a coin has 20% stales because it has 10s blocks, the calculation coinchoose/coinwarz has is way off (by 20%). I believe Multipool uses a more conservative estimate of stales than those sites as well. You are free to mine DGC and WDC directly and see if you can beat the estimates. Although I don't recommend it  |

The profit calculations for LTC, TRC and FTC just went away, so it is defaulting to the next highest.
EDIT: I think it is because BTC-e is down.
I added bter as a secondary.. This problem should hopefully not happen again. |

Am i not allowed to start mining Terracoin if Litecoin in the middle of the header on the page?
I have been trying everything to connect to stratum+tcp://multipool.in:3333 to mine TRC but i cant. I am using the correct username and password too.
The one listed in the middle is just what the port 7777 one is using (the switcher). The rest are separate. What issue are you getting/what error? "pool 0 JSON stratum auth failed: (null)" Also i am using the worker and pass. Not my login info. The pool doesn't check the password, so that means your worker name is probably misspelled. |

1) Can we have a client that changes hardware depending on the necessary algorithm?
Device profile asic for sha-256
Device profile gpu for scrypt+sha-256
I think someone would have to create that on their own, unless flounder (or someone else) created an app that would interface with the server and automatically close/launch the miner with the appropriate flags when it goes from scrypt to sha-256 coins. Yeah, you'd need to ask the cgminer (or other mining app) developer to implement that. I don't know if the software can autodetect the algorithm, although since stratum is http-based I could probably add an X-header tag or something. From what I've been able to gather, only the initial calls are http. If the call (getwork or getmininginfo?) returns a x-stratum header, cgminer then tries to connect to it. Subsequent calls are over that "stratum+tcp" protocol, and there are no headers, just the json values going back and forth. I also believe at the miner level, you'd have to stop and restart the app, so something running locally could periodically query an API for "most profitable algorithm", then kill cgminer and reopen it with a different config file specified. On the pool end, you could just have a different port for each script, and the miner's config file points to the right port/algo. Well, when the multiport switches, the miner has to make a new connection so I'd assume it will receive the X- headers again. Not sure if the miner itself will look at these, though, or disregard them. |

I'm compiling NVC on a t1.micro instance right now.
My plan is the following: If things go well (i.e. if the micro instance is sufficient to handle the load of novacoind + stratum server, which it should be, in fact I may be able to put 2 coins on it) I plan to sell 10,000 WDC (~1 BTC, heh) from the pool reserves (about half our WDC reserves) to purchase a 3 year heavy utilization reserved instance ($100). The recurring charges for the instance will then only be ~$10 per month. ($3.75 for the server at $0.005 per hour, plus bandwidth and I/O, both of which should be fairly low.)
If things work out, I will probably move the other coins onto their own micro instances as I receive funds. That frees up the current server to be a dedicated DB and would potentially allow me to move it outside of Amazon if I want to.
Anyone see a flaw in my thinking?

MySQL changes are complete. Also, I reduced the cache times on many of the cached variables to 120 seconds. Which means you should see things like hashrates, etc. update a lot faster.

Ok so it's not something that's a result of say a 51% attack on CNC, it's just people pumping out different clients.
That's not a bad thing then.
CNC is still alive? |

Looks nice, but if so, that 1/2 oz silver 10 LiteCoin round is still only worth 1/2 oz silver, about $10 -
If its current rate of 10 LTC =  at least. Not sure where you get $10. Current price of silver is $21.81 oz, So that half oz coin is worth $10.90, it dosent matter what it says on it, you can put anything you want on a silver coin, its easy to do and it dosent make it worth anymore, silver is silver. It would be stupid to pay $20 or $30 for a $10 piece of silver. I'm assuming that these will each be loaded with the private key to 10 LTC - like the Casascius Bitcoins. So $10.90 plus $23.79 plus premium to cover manufacturing costs and some profit for the guy making them. Gotta be looking at around 40 bucks each. Yea but when you go to sell them no one is going to pay that premium you spent, so your losing money on them.. They are strictly souvenir coins. A big enough company puts any design on a coin they want and sell them for pennies above spot... apmex.com - providentmetals.com - I am a gold and silver investor, I never buy anything with a premium, because your just losing money on it, but thats just me... You should shut up now and look at casascius.com. If you compare brand new physical litecoins to 2011 unique and funded Casacius bitcoins, you are going to have a disappointing experience. I wasn't comparing them; Aquaman is talking about these like they're just silver coins with the Litecoin logo stamped on them, he doesn't appear to understand that they're preloaded with LTC. |

Maybe you could add a leader board for donation % if you get a chance. Try and get some competition going there.  I noticed my donation percent drop back to 0 at one point a couple days ago, but then I set it back again and it seemed to have stuck. Hopefully it's working like it should now, it claims to be on. It's on the short list of things to get done, along with detailed block payouts and personal payout history. I'm at a client site for work today and tomorrow so it'll probably get done sometime this weekend. |

It looks like if I move the shares tables to the instance store partition, I could save quite a bit on I/O costs. If the hardware ever goes down, we would lose that data, however, I could easily backup the shares tables every hour to an EBS volume. I think the risk of losing an hour's worth of shares is probably worth saving ~30-$40/month.
I've also identified an issue in the LTC shares table that, when fixed, should speed up the estimates calculation considerably. I will be implementing this sometime tonight during a MNC mining window.

really diggin' this pool. suppose this is a free bump then
I'll take it! How are donations going so far towards the increased costs of the server, btw? Practically nonexistent! Of course that may have something to do with the bug that was resetting everyone's donate percent to zero... Which is fixed now! Definitely possible. Also, your changes to optimize the site should hopefully reduce the costs by a bit (or a lot). Hopefully! Well, we're currently on an m1.medium instance at Amazon, which is around $95 a month not counting I/O, and to add more coins I'd really need to go to an m1.large or change the architecture a bit so that we're not using just one server. |

wont go mining terracoin ( might be intended as site says still mining ltc and its not scrypt tho)
Yeah the multiport will never mine terracoin since it's not scrypt. At some point I will add a SHA256 Multiport. |

It's nothing obvious.. I think it may be a deadlock that's only happening intermittently. Added a few debugging lines to the estimates script.

Are you making updates to the DB? The round shares keep disappearing? And then they come back, and go away again over the last 30 mins or so.
There's something going on with the estimates script, looking into it. Shares are not being lost. |
