My 290 ran at 96C when mining at 820kH/s (the highest stable I could get, but then again my card seems to be a crappy one. Driver crashes alot when i stop mining and restart etc.)
Now it runs at 65C with watercooling and the same 820kH/s. If i increase intesnity the kH/s decreases. Sux...
I think there is a ton of variance in the power / heat attributes for R9 290 cards. I have two sapphire 290's. Both hash very stable at 875Kh/s with the exact same settings, but the first runs at 73C at 60% fan while the second goes over 95C even with 75% fan, which forces me to run the fan at 90% and temps are still 88C. So 290 #1: 73C at 60% fan 290 #2: 88C at 90% fan To make it an apples to apples comparison 290 #1: 62C at 90% fan 290 #2: 88C at 90% fan |

I admit I don't like this given GhashIO's history.
But when I first got into bitcoin, Deepbit (remember them) was 80% of the hash rate and they had 80%for a long time.
Deepbit at 80% didn't destroy the network because: 1) that is not in a pool's interest and 2) any attempts are highly public and would result in the majority of your subscriber base immediately leaving.
A pool is only as strong as the trust individuals place in it.

Unfortunately, John K seems to be missing in action for a while now: https://bitcointalk.org/index.php?action=profile;u=31288Name: John (John K.) Custom Title: Global Troll-buster and Posts: 9129 Activity: 770 Position: Staff Date Registered: June 30, 2011, 10:14:50 PM Last Active: November 29, 2013, 09:26:22 AM The bitcoin address from his profile has received 1,369 BTC over the years. https://blockchain.info/address/1NB1KFnFqnP3WSDZQrWV3pfmph5fWRyadzAnd that is just the one public one, John K has been active from early on. Perhaps the guy got tired of intermidiating message board squabbles and finally retired, I'm sure he has the means to by now. |

The number of coins available on the exchanges has been decreasing for over a year now. Also, the few coins that are left are spread over more exchanges.
That is probably due to the fact that the price has gone up around 100x in the past year. In early 2013 when coins were around $10 if you wanted to trade lets say $50K you would need 5,000 BTC. But now that coins are around $1000 to trade $50K you only would need about 50 BTC. The exchanges are used for active trading, not long term storage. Long term coins withdrawn out of the exchanges. So it makes sense that as the price goes up the market needs less BTC for trading purposes. That said the dollar value in the exchanges has definitely gone up.... |

ok I tried to explain it in simple terms, guess I failed, but here is the bitcoin wiki that says : While Fractional Reserve Banking with Bitcoin is possible and already implemented with CoinLenders ........ Source : https://en.bitcoin.it/wiki/Fractional_Reserve_Banking_and_Bitcoinagain you can fractional reserve bank anything, if you do not understand this, then you do not understand fractional reserve banking, it is just an accounting scheme. It is done with fiat, it was done with gold when gold was the currency and there is no reason why it can not be done with bitcoin. You are showing the most basic and most predictable of all human responses: denial You are missing a very important aspect regarding fractional banking, it requires an entity that can bailout banks and stop a run. When we were on a gold standard banks implemented fractional banking on a much more limited scale, around 2:1, and still runs that wiped banks out were common. In today's fiat world the banks are levered over 10:1. The only way this is possible is because the FED can stop any run in its tracks by providing on demand liquidity, so runs are impossible becuase there is an entity that can bail them out. In order to provide "on demand liquidity" the FED essentially needs the ability to expand the money supply on demand, i.e. print money. In Bitcoin, this ability does not exist and there is no bailout entity that can provide on demand liquidity. Yes, the bankers will try to implement fractional banking on top of bitcoin, but they will be burned without a FED who can print bitcoins. tl;dr Wall street can and will fractionalize Bitcoin, but without a printing press those attempts will fail, causing people to not trust or give their bitcoins to bankers who fractionalize, which in turn will prevent bitcoin from being fractionalized in the manner you describe. |

How do you 'start' your cgminer? If you use a batch file with drillbit options and you also saved your cgminer configuration, be aware that the settings are also saved in the cgminer.conf file. When you change the settings in the batch file that does not alter the cgminer.conf content and the batch file may not override those. I have fallen into this trap in the past, just want to make sure that you did not.
I agree that the USB cable does not seem to make a difference in my case.
Good luck
Not sure about others, but I have not been able to keep my single drillbit 8 board up for more than a day or two without cgminer crashing. It seems to be USB related on a raspberrypi. cgminer hashes fine for a while, then kicks out errors regarding incomplete packet sizes and then crashes. After having to constantly monitor and restart, I now just wrapped cgminer in the startup script below (thought I'd share it in case anyone else needs a quick/simple way to auto-restart cgminer). It simply monitors cgminer every 5 seconds and launches a new cgminer if the previous one crashed, this has worked fine and I no longer have to keep monitoring the board and manually restart. If anyone has any ideas on why my cgminer might keep crashing, please share. #!/bin/bash
while [ 1 ]
do
sleep 5
status=`ps -aef | grep cgminer | grep -v sudo | grep -v grep | wc -l`
if [ $status -lt 1 ];then
echo "Restarted cgminer on: `date`" >> drillbit_log
~/drillbit/cgminer/run_drillbit // batch file to start cgminer with specific options
fi
done

What app are you using for coinbase limit orders? I've developed it, I thought I'd do some more testing and release it in a week. //although there is app for Android made by someone else - Coinbase Trader Please release and open this up on github when you are ready. I (and I suspect many others) would be interested in using and contributing to this. I've asked coinbase if they plan on adding this feature and they never reply back... |

Barn said on the other forum that they would be doing a 16 chip Avalon gen 2 board. They won 5000 chips in the Avalon design contest.
That could be interesting if they get the price right, the Avalon chip is not as fast as the Bitfury, quite a performance gap actually, but ultimately it's $ per GH/s that matters. After being very badly screwed over by Avalon this summer (with 1000s of other people) I will never buy any designs based on them, and suspect many feel similarly. It's not just $ per Gh/s that matters, but I'd consider W per Gh/s to be most important since this is the metric that determines "when to turn it off", the lowest W/Gh/s chips will be the last ones standing. Avalon is much weaker on W/Gh/s than others. And that's if they actually give you the product you paid for and don't auction it to a higher buyer. |

So now that the boards are back and happily hashing away, what is the status of future batches? Does drillbit plan future batches or indivdual sales? Also are you guys looking at designing boards around future chips, for example black arrow or others?
And thanks to barntech and team, after being burned in an Avalon GB (very badly) I appreciate how you guys stuck with it and made things right. Sure it was disappointing to lose time, but new HW designs sometimes have issues and you guys went out of your way to quickly solve them.

Citizens do worse then nothing, they keep on voting pro police state candidates from BOTH parties.
The entire occupy movement is an astroturf retaliation against the tea party who are the only people who actually protest the loss of our freedoms. Tea party is enemy #1 for the republicans who ally with the democrats against them.
The is why the MSM labels the Tea Party as a bunch of ignorant rasist hicks. When in fact it is the complete opposite and represents a true awakening of the people. It's reached the point that the government is sponsoring studies to shift public perception of the movement. Last year the government gave $400,000 to a Yale professor to "conducted a cross-analysis of intelligence and political affiliation, expecting to find that people who identified with the tea party knew less about science than the average person."The professor did the study expecting Tea Party members would score worse. Instead he found the opposite and that “Identifying with the Tea Party correlates positively … with scores on the science comprehension measure.” This shows that: 1) The MSM/Gov is actively trying to discredit the movement 2) The MSM/Gov have successfully brainwashed people to discredit the Tea Party and create bigoted impressions of the people in the movement (in this case a Yale professor) and 3) These stereotypes are not based in reality. http://dailycaller.com/2013/10/17/prof-sets-out-to-prove-tea-partiers-are-stupid-admits-he-was-wrong/Yep, that's right. I was talking to friend about the Boston bombing that happened recently. He was all happy that the LEOs handled it so quickly and kept talking about what a great job they did. All I could see when looking at the still images and videos was flash backs of studying WWII Germany. Jackbooted soldiers marching into peoples homes without Martial Law and without a warrant. Scary!
IMHO this was the most scary thing in all of 2013. Not the "suspension" of constititional rights but people's acceptance of it. It shows how far the independent mindset in the US has fallen. |

Go over and look at Japan's situation, I forget the exact number but if Japanese bonds go to around 2.1%, interest payments on gov debt equals tax revenue, meaning that they would have to print 100% of any government expenditures. Oh and that number decreases every year due to their high deficit. In not that many years a 1% interest payment will break the BOJ. Don't forget, this is why satoshi created bitcoin, and why these short term price fluxuations are meaningless. |

so why the fork?
Because after the Molecule fork the dev lost his ~5,5% premine. With Atom he'll be able to keep it. So MOL=> fair coin now  Why would a fork cause the premine to disappear. Any coins held prior to a fork should be present on both paths. The differences in two chains that forked only involve transactions that happened after the fork. |

That's like saying "the Facebook ecosystem has the potential to double" way back in 2006. People who look at Bitcoin like a stock and speak in those terms don't get it. |

People need to cash out slowly. Imagine, if just 2% of all people cash out quickly (or everyone just sells 2%). That would be 240,000 coins hitting the exchanges. Look at the order books and make your own guess...
Remember that if someone is going to dump 1000 coins on Gox now, we would approximately go down by 40 USD. The guy doing that would have pocketed around USD 880.000, but the Bitcoin marketcap would decrease by USD 480 Mio.
EDIT: (not implying that one person can move the market as such, I just want to point out how fragile the whole wealth in Bitcoin is)
No market of any size can support immediate liquidation of 2% of the entire market value. If people tried to quickly cash out 2% of the world stock of gold, the price of gold would crash. If people tried to quickly cash out 2% of all housing, the housing market would crash. If people tried to quickly cash out 2% of all gov bonds, the bond market would crash. If bitcoin is a store of value, 2% won't be quickly cashed out. The market does not have to support that. |

Like most here, I gently smile when I read one of those many mainstream articles claiming "Bitcoin could take off, but they really need to implement reversible transactions". It's a feature, bitch, not a bug.
But I *am* aware that reversible transactions are not per se bad. In fact, in many cases you might want something like that. Enter Paypal.
I have no idea if they're smart and nimble enough to see this huge opportunity, but if I were them, I'd at least have a small internal team dedicated to the possibility of setting something up like this, exploring the legal framework necessary to pull it off, etc.
Great insight, thezerg!
The simple quick answer is if reversible transactions are desired, yes they are possible by layering another service on top of bitcoin. Bitcoin is a protocol and you can build anything on top of it. For example paypal itself could offer a bitcoin service with reversible transactions. Here payments are given to paypal in a users account, and the bitcoins have to stay in the account for a certain period of time. During that time paypal could reverse the transaction since they still have the coins, and after the time period allow the receiver to withdraw to an external account. The service would cost x% of the transfer. Now people/merchants can decide for themselves if they want to use the service or not. Merchants can say, you can pay me X BTC for direct payment or X+4% for through paypal service. Now people that trust each other don't have to pay the fee. That's how a free market and individual choice works. That is what bitcoin is designed for. |

i can't read it, it all.  Then ask someone who is a native german speaker or you'll allways have problems with such translations.
This could lead to big missunderstandings.
Well since it seems you obviously can read German, I think adamstgBit was asking you for a translation. Are you going to translate for him as he asked, or just make mean comments. |

Panckage, are you suggesting making middlecoin into several pools and then spitting the miners up amongst them (such as middlecoin1, middlecoin2, middlecoin3) and having them all use middlecoin as the front end?
Yes that's it I've been wondering why that isn't the default approach for awhile now. It makes much more sense to spread out the hashing power over the top 4-5 coins, with weighting based on profitability (i.e. the 5 five coins could get: 30% then 25%, 20%, 15%, 10%). This way if the price drops on the coin you've been mining, the impact is much less. It also utilizes the pool's hash rate better. For example let's say the target coin has a low hash rate around 50Mh/s, in this case allocating 100% of the pools 1.6Gh/s at the coin is no better than allocating 33% (around 500Mh/s), both will capture almost 100% of the coin's blocks, but this frees up hashrate for other coins as well. |
