Design type: 100% Hand routed for performance density
Bullshit. They should change the supplier. They must have found the shittiest design and verification engineers on the planet to get such low from a full custom 65nm asic. Further, for a chip with such little logic on it their yields are crap. My guess would be they used shitty engineers and global foundaries' standard cell library, the engineers didn't setup their simulations correctly and as such the cores fail under even the slightest real world heat. This guess is additionally backed up by the high hardware error to accepted rates posted in screenshots by various Jalapeno recipients. I would guess that the estimated hash rate on the pool side is much lower than the promised 5 gh/s. 12 posts and already trolling, what's the name of your other account? |

Bullshit. They should change the supplier. Global Foundries are the world's second largest independent semiconductor foundry. It use to be called AMD if you remember that little company, they sold off their fab which became Global Foundries, they are not noobs. |

anyone else notice how the moment cryptsy started implementing a chatbox, that DGC started falling?
i think it was due for a bit of a correction anyways, was experiencing too much growth too fast (350% growth is less than a week is too fast)... but i think it's more than a coincidence with the damned trollbox on cryptsy now
Baritus if you have any influence over vircurex deciding or not deciding to adopt your currency, if you can ask them to never implement a chatbox that'd be awsome. people just use them to co-ordinate pump and dumps it seems like, very little information about the curriencies exist except for people to wield as a tool to make money off of quick then get rid of it.
they're impossible to moderate, and there are no real laws prohibiting people conspiring to control these crypto markets, at least no laws that i know of, so it's the wild west...
problem is, that the exchanges end up making more money the more activity there is, therefore trollboxes generally increase trading and make them profit, while making the currencies volatile, and eventually decrease in value it seems.
anyways, just my opinion
The Cryptsy chatbox has been there for weeks, maybe you only just noticed it. |

I've been mining on 7777 for just a few hours now and I noticed that it switches coins a lot more than I would have expected. It would seem some kind of smoothing algorithm could help that. But the real question is - what does this do to the PPLNS calculations of the coin pools, since that is designed to discourage hopping.
Don't get me wrong - I love the idea of having an automatic way of switching to a more favorable coin (though there may be other criteria than instantaneous profitability to use to base the switch on). I'm just wondering what other considerations we might need to make beyond PPLNS (like expected time to next block) in deciding when to switch (or when not to).
This could be an interesting community discussion!
Right now there isn't any smoothing at all. It's definitely something that I can look at in the future. The last N for most of the coins is so low that the PPLNS hardly matters. But for LTC, you are talking about an average of around 2.5 million shares per block, so your shares aren't going to fall out of the last N that often. If that does happen, it means that the LTC pool is having an extremely long round, which means you were probably better off mining a different coin anyway. It needs a stronger averaging. It jumps around like Coinchoose. If you have 5 different coins as the most profitable in the past 24hr, and a coin that is always the 2nd or 3rd most profitable, the chances are you should have been mining the 2nd most profitable all along, not the most profitable coin. You would be able to tell this from a moving average. |

I don't see why anyone would mine NMC directly when its profitability is only 6% of Bitcoin's.
That's what merged mining does to a coin, it's needs to be able to breath on it's own without being tied. |
|
|
|
Quite true, BTC can take days, NMC is another SHA256 candidate, I don't mean merge minied, just mined by itself. I think that could be popular too.
Wouldn't it be more profitable to merge mine NMC though? You would still have to find BTC block wouldn't you? |
|

The reason you have a loyal TRC following is the only other pool I know of is Coinotron, except for BTC, SHA256 coins are woefully serviced.
Why not make a SHA256 and a scrypt version of the pool?
I would like to see TRC in rotation with PPC and BTC. That should attract a fair few from the new crop of smaller ASIC owners.
Yes that is the eventual plan. PPC needs some changes to both the mining software and the frontend, I believe. We don't have a snowball's chance in hell of finding a BTC block in any reasonable amount of time until we have around 500GH on SHA256 though.

I have considered going all-scrypt, but we have some very dedicated TRC miners on the pool (it was one of the first coins I offered) and I do want to eventually include BTC once we have enough SHA256 hashrate. As far as your db suggestions, I agree that there could be much improvement on the DB side. But even then, $150 a month is a bit too much for me to keep spending on something I'm not making any money from  I may try to cobble together something from the equipment I have available if I don't see much in the way of donations. The reason you have a loyal TRC following is the only other pool I know of is Coinotron, except for BTC, SHA256 coins are woefully serviced. The PPcoin devs haven't even made a port of p2pool for it, and how long has it been out? Why not make a SHA256 and a scrypt version of the pool? I would like to see TRC in rotation with PPC and BTC. That should attract a fair few from the new crop of smaller ASIC owners. |

I watched the timer countdown, kept refreshing the page until the download link appeared, grabbed the client and launched it, by the time it was open and syncing we were already up to block 176, how can this be?
No p2pool ready on launch, another failed coin for miners with not enough hash rate to solo.

Screw? Do you mean escrow? The service is nothing like an escrow. It's an anonymity service. Anonymity is a key selling point of cryptocurrency in general, and we're improving upon it. Blockchain tracking is still possible (obviously), but the data gathered will be worthless, due to the nature of how the coins will be mixed up. More specifics about this feature will be posted soon.
1 hour until launch!

multiport is awesome but it seems to be down now.
Yeah, been down for around 20m or so,  still down Have you tried port 17777 as well, the non-stratum one? That one is working for me just port 7777 is down. |

great research and presentation, but name sucks... the name itself will be the end of the coin.
stable 1. a. Resistant to change of position or condition; not easily moved or disturbed: a house built on stable ground; a stable platform. b. Not subject to sudden or extreme change or fluctuation: a stable economy; a stable currency. c. Maintaining equilibrium; self-restoring: a stable aircraft. 2. Enduring or permanent: a stable peace. 3. a. Consistently dependable; steadfast of purpose. b. Not subject to mental illness or irrationality: a stable personality. 4. Physics Having no known mode of decay; indefinitely long-lived. Used of atomic particles. 5. Chemistry Not easily decomposed or otherwise modified chemically. The name encompasses a lot of what we hope to achieve. We thought it was fitting A place where you put horses. A horse icon would be nice hay. |

Most of the Jalapenos through paydate July 31 have shipped. Sometimes an order can get hung up in the shipping software. Sometimes an order doesn't ship because the customer has not logged into his account and accepted the new power consumption. So I say "most" have shipped through that date. One person wrote on the day I was processing his order to go to production and said, "I am tired of waiting; refund my money." Knowing how much the rest of you wanted that product, we refunded him.
Early August orders have been sent to production. https://forums.butterflylabs.com/blogs/bfl_jody/183-thursday-6-6-2012.html Just a Note about this Blog

Let's get clear about our agreement here. This is a SHIPPING blog. I agree to tell you the shipping dates of the products we are shipping every day so you can have some idea where we are in the queue.
Some people ask me to share the order numbers. These are not relevant, since we ship by pay date. It would tell you nothing. Sometimes we had to assign a large number to an old order because it got lost. The order numbers are only for reference, not shipping queue. |

Hi BkkCoins, I would like to ask for your opinion on BFL offer we got today at https://bitcointalk.org/index.php?topic=223571 . They are willing to sell us (as GroupBuy) advanced 65 nm chips (4 GH/s per piece) on 100% escrow (John K.), on-time-or-deal-is-off policy. Is developing and producing mining boards capable of running those chips more challenging than for Avalon's 110 nm ones? Would you be interested? (Avalon boards are surely to stay the top priority.) Since, I'm refining the deal right now, I can use any suggestions about documentation, sample chips etc. I should require for you/other developers as part of the deal. Thank you. BFL haven't release any technical data on the chips as far as I know, so you would be flying blind trying to work out what's needed. |

Has PPC been added, I have not found a public PPC p2pool yet.
I was told that PPCoin will not work with P2Pool because it is a Proof of Stake coin and not Proof of Work. I would love to add it but it's just not available. Very sorry.  YAC and Namecoin are both PoS aren't they? Both are derived from PPCoin code, and they have p2pools |

Batch #2 Avalon
How big was that? I heard estimates of around 40TH/s a while ago, did that eventuate? I believe 600 units @ 70? or maybe 72 Gh/s per unit. I also believe that it has started shipping, but there are more units to go before the shipping of batch 2 is complete. 40 - 43 Th/s yes So if the current net hash rate is 117TH/s, that batch alone represents 35% of the total net hash rate. Add that to the 20TH/s from batch #1 and you can see that over half the entire BTC hash rate is now concentrated down to 900 Avalon boxes, even less when you count users, since many people ordered more than one Avalon box. |

That's the problem with the rev.2 pcbs. The voltage is dynamic by the way so no surprise that it went from 1.25 to 1.2 but 1.2 is still wayyyyy too high. The Accelero Extreme will only be a band aid because it will still run hotter than it should. I'd send it back if possible and get a non ghz edition and make sure it's rev.1 if it's Gigabyte. Not directed at you but what's with all the thread necros today?  Is there a firmware I can use to get the voltage down a bit more? |
