How do I get the gpus to show?
If you're running the 2.1 version of the SDK, then your GPUs may not be supported. I haven't actually set up a miner with 2.4 yet, but I know 2.3 supports all the current ATI GPUs up to the 6990s. To update your SDK, change all the references to 2.1 that you added to your .bashrc to 2.3, then remove the 2.1 SDK folder, replace it with the 2.3 SDK, and rebuild pyopencl. If you really want a clean start, you can reinstall Ubuntu and then run these scripts I threw together. http://ryepdx.com/bitcoin/prep_up.shhttp://ryepdx.com/bitcoin/up_all.shYour computer will reboot after running prep_up.sh. If you don't like that, remove the "sudo reboot" command at the end of the file. |

This is one of the drawbacks to having a distributed peer-to-peer network: it takes time for changes to propagate to all nodes. On average it should take around ten minutes for a transaction to show up, but this obviously depends on how much the network is being strained at any given moment. Also, paying a transaction fee with your transfer puts your request higher up in the queue so it ends up being processed faster. Good to keep in mind if time is of the essence.

It probably does not really require much of your time at all, just your money.
You need to put up enough money as a "float" for the service to operate with and to cover any losses due to either
(1) The statistical losses due to reversed incoming fiat transactions happening before the padded fees/exchange-rate has accumulated enough to cover them; or
(2) Your estimation of the amount of padding and/or fees falling short of what turns out to actually be necessary.
I'd be willing to put up a couple thousand to help cover initial losses, provided my initial investment would entitle me to at least having that investment returned once things get rolling. My financial reserves aren't that great, however, as I'm currently in the middle of trying to set up a mining cluster. That all said, please specify the fees and/or exchange rates you are prepared to put up the float money for such a service to operate with. I would want to get some stats on what percentage of payments get reversed across a range of services, such as PayPal and a good sample of credit card processors, in order to calculate out what kind of premium would need to be charged initially in order to keep the service from going immediately under. Once the service has been running for a while, the premiums could be adjusted to account for actual chargeback rates. An additional fee should be charged on top of the bare "chargeback compensation" fee to help keep the service running as well, part of which should go to a legal defense fund. I imagine such a fund would be necessary at some point in the service's history. Better to be prepared than caught flat-footed at any rate. Coding is pretty much irrelevant, no need to consume your precious coding time, all that is needed is your float money and the fee and exchange rates at which to utilise it, and likely someone can be found to do the day to day operations including running whatever already existing or easily modifiable code will work, maybe even for less than minimum wage just because like you they just want to make such a thing available for the good of the community.

Yeah. This is the part I have the most trouble with just because I'm a programmer and thus feel weird hiring someone to do something I feel like I could do myself. I guess it comes down to time constraints though and the whole time/money trade-off. I should figure out how much this thing would cost to get off the ground. |

You are actually complaining about fiat currency, but you are mis-directing your complaint by trying to make it sound as if the problem is with the non-fiat currency.
Wrong. I am complaining about the gateways to bitcoin that are available. Because the majority of the world still uses fiat currency this is an issue that merits some discussion. If you had an actual money to begin with, people would accept it for bitcoin readily and easily.
For example you can buy bitcoin with pecunix or with liberty reserve, and if the feds had not shut down e-gold you'd be able to buy it with e-gold too.
But most of the world does not have Pecunix or Liberty Reserve, and most of the world doesn't want to have to go through another currency to get bitcoins. I don't care if I can get bitcoins with Pecunix or Liberty Reserve. I want to buy it directly. It's a major PITA to have to do this. It's a barrier to entry that is entirely unnecessary and you are only holding back the adoption rate by refusing to do anything about it. It is not our fault that the fed shut down e-gold, thus limiting your options slightly.
You're right. Not your fault. But it is the fault of the community that we don't have convenient gateways in place for average consumer types who just want an easy way to make transactions online. Don't try passing the buck here. The problem remains, regardless of whose fault it is. I don't care whose fault it is. All I care about is seeing the issue solved. If you find that buying bitcoin, liberty reserve, pecunix etc using fiat is made hard for you, go complain to your congresspeople or ombudspeople or what not telling them you don't want them reversing your transactions and so on. Or complain to your credit card provider about their giving you a hard time buying electronic currencies or something.
Sure, that's one way of doing things. You can go complain to someone else until they fix things for you. Honestly though? I doubt they care. I'd much rather see someone take this into their own hands and provide something now than see people sit on their hands until someone solves their problems for them. Once you have something reasonable in hand you are fine, a lot of blockchain based currencies become accessible easily once you have some bitcoin for example, since a lot of them don't care to bother at all with fiat, letting bitcoin serve as gateway to that stupid world so they do not have to.
-MarkM-
Calling the world most people live in "stupid" does not make that world go away. The practical barriers still remain. The problems still want to be solved. You know what? Screw it. I should just make this service. Anyone else interested? I'm working for a startup as their sole programmer, I'm trying to get a little bitcoin service called Bitcoin Pouch off the ground, I'm trying to learn Scala and implement yet another service in it, and I have to leave enough time for my girlfriend so she doesn't start to feel ignored. I'm a little swamped. Help would be greatly appreciated if I'm going to manage anything in this direction. |

So, the worries I've read on this forum about a single pool becoming larger than 50% of the network and giving its members or administrator the power to double-spend are completely unfounded?
No, not completely. However, so far the bitcoin economy has proven very good at self-regulation. An example: Deepbit did reach the > 50% mark recently; in response, a lot of people left the pool and joined other ones. I don't doubt that this level of corporate responsibility is due to the quality of our community. At the risk of sounding pompous, I think most of us here are of above average intelligence. I have good reason to think so: most of the discourse here is pretty well-informed, and most early adopters tend to be of the aforementioned set anyway. Highly intelligent people tend to enjoy new ideas and are more likely to adopt them. Eventually bitcoin will go mainstream and with it will come the risk of monopoly as less conscientious users begin to pour in. But as long as the majority of miners remain both intelligent and socially conscientious, we should be good. Though creating a decentralized mining pool would be awesome and a really, really effective long term solution to this potential problem. I'd be happy to see such a project come to fruition. :-) |

Seems like the creation of bitcoin harms, rather than protects, the US Dollar.
Not necessarily. The only way it could hurt the US dollar is if the bitcoin economy becomes large and free-standing. If it becomes possible for nations to buy, say, oil with bitcoins without once converting to USD, then that would hurt the USD. I'm sure there are plenty of things the CIA could do to keep that from happening. If that never happens, if bitcoins remain a proxy for fiat (as they kinda are right now), then the US dollar doesn't take a hit and the CIA benefits greatly. Secure and anonymous transactions of large sums of money? I'm sure they have a use for that. |

Your granny can understand it, its simple, go to a site to buy them, enter address, buy them and get money, and to buy something send the money to the address with it and receive product.
The obnoxious thing about bitcoins, in my opinion, is acquiring them. Paypal was probably the simplest way until that option was taken away from us. Dwolla is easily the next best thing for the average consumer now, but transferring funds into Dwolla is a looong process. It takes about two days, in my experience. I haven't tested using Dwolla to transfer funds directly from my bank account to, say Mt. Gox, but I don't imagine it's much faster. (Correct me if it is.) Most people don't have Dwolla anyway, and once you have a Dwolla account why not just use that to make a purchase? If you don't care about anonymity and if you're not looking to escape the fiat system, then for most purchases Dwolla makes more sense. I think the killer application for bitcoins is fast and secure currency transferral. Right now it really isn't all that fast for most people as most people are trying to go from fiat to bitcoins to purchase. That process can take a few days at present. Two if you have a Dwolla account and need to transfer funds in. Four if you don't have a Dwolla account or don't have your bank account associated with your Dwolla account. Best case scenario? I enter my credit/debit card info, the information gets verified, the card gets charged, I get bitcoins. I wager most people would be willing to pay a small premium to offset the cost of scammers if it meant getting bitcoins in their wallet within ten or fifteen minutes. It would be a boon for the bitcoin economy, too, as it would lower the barrier to entry for most people and would allow people to "strike while the iron is hot," so to speak. If someone catches the "bitcoin bug" and wants to buy bitcoins, they shouldn't have to wait more than an hour before they have bitcoins in their wallet. Just my 0.02 BTC. Also, the address system is a bit intimidating for most normals, I wager. I think web-based services which allow users to send currency by e-mail address or by name would be the best option for them. It would make the whole system a lot friendlier and a lot more pleasant to use. |

The solution is Linuxcoin, in this thread. This is a bootable iso image: its not Ubuntu, but it is linux, and everything is installed, and it runs all 6 cores of my 3 6990 cards.
Meh. This doesn't help me. I tried Linuxcoin and couldn't get it to boot. :-/ Thanks though. |

I've been having similar problems getting my 3 cards working. I have two 5970s and a 6990. My issue is identical to the one minty had initially. I see the Ubuntu logo, and then nothing. The monitor (plugged into the 6990 in PCIE_1) gets a signal, though, and if I plug it into the second 5970's top DVI socket I get a "Signal Out Of Range" error on the monitor. :-/

How hard would it be to make this plot a curve based on a handful of user-provided points or a table? The configurable curve in MSI Afterburner is very nice for this purpose.
I'd certainly pay some kind of bounty to see that implemented.
Can't you do that with Overdrive in Windows and AmdOverdriveCtrl in Linux? |

Hey gavin, btw do you know the date of the conference?
or is that not to be disclosed?
+1 I third that one and wonder aloud if he's keeping it secret to avoid creating sharp fluctuations in the market as that date nears. |

You buy what you gotta buy when you gotta buy it. It's no use hanging on to something thinking it's going to go up forever. |

I don't want to sound crude or judgmental but damn you surprise me a whole load of stupid. I'll use Amazon for example, they accept fiat right now and not BTC too bad. But if you buy something they'll take it back no matter what it is DOA or not, and if they don't contact your credit card company and show them a copy of their guarantee and you get your money back the same minute. With BTC, once you transfer your coins they are gone. Plus, with you talking about bank transfer and iDeal and all this other non protective garbage that's exactly like BTC. So my questions are asking how can we as a community come up with a solution or they may already be one, like Clearcoin. Bottom line is don't come on these forums and write stupid shit. Thanks. Either say something smart to help or shutup.
Sorry if the others are a little touchy. The question you're asking gets brought up a lot by people new to the forums, particularly as an argument against bitcoins. This is probably why you've been getting condescending comments from certain corners. There are a lot of people out there who fail to grasp that bitcoins are a bit of a cash analogue. As for your concerns, there have been a number of ideas floated on the forums. ClearCoin is probably the most successful consumer-protection service so far. The Bitcoin OTC web of trust is also pretty effective, though its interface is a bit byzantine and out of reach for most users. If you'd like to start a consumer advocacy group or service, go for it. If you want to see what's been done so far, search the forums. I couldn't tell you off the top of my head though. Sorry. |

the install went good, but at the end i realised, that my system 32bit, and not 64. but should i rewrite?
Yes. Remove the files you just installed and start over with the search-and-replaced Inaba guide below: Here are the steps you need to take to get mining on Ubuntu's latest 32-bit OS: First, install Natty on the HD of your choice, accepting all the defaults as appropriate.Once you are booted into your new OS install, do these steps in a terminal window, or if you wish and it's easier you can do it from an SSH session. Optional First Step (Skip this if you don't care about SSH):
Optional 1: Press the upper left 'start' button on the desktop and in the search field enter 'terminal'. Click it and open a terminal window.
In the terminal window, type:
[b]sudo apt-get install openssh-server[/b]
This will install the SSH server. Once the server is installed, you can connect to your machine via SSH and perform the rest of the steps listed below.
END Optional First Step 1. sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
2. sudo apt-get update
3. sudo apt-get install screen
4. screen -S update sudo apt-get install fglrx vim openssh-server g++ libboost-all-dev subversion git-core python-numpy

30. chmod +x phoenix/phoenix.py poclbm/poclbm.py5. sudo aticonfig --initial -f --adapter=all
31. sudo aticonfig --initial -f --adapter=all
32. sudo reboot
You should now have a fully functional Ubuntu 11.04 mining rig with Phoenix and poclbm installed. To test it out, you can go into the poclbm directory and run poclbm without any switches and see if your graphics card(s) show up. Do this with: cd poclbm
./poclbmIt should list your CPU (possibly) and your graphics cores available. Here's a couple useful tricks for working with your graphics cards: To display the temperature of your cores: aticonfig --odgt --adapter=all To display the clock speeds of your cores: aticonfig --odgc --adapter=allTo show or set your fan speed: Shows fan speed aticonfig --pplib-cmd "get fanspeed 0"Sets fan speed to 100% aticonfig --pplib-cmd "set fanspeed 0 100" If you have multiple cores, you'll need to export a different display variable to access the different cores, like this: Show fan speed on 2nd card: export DISPLAY=:0.1; aticonfig --pplib-cmd "get fanspeed 0"You can change the .1 to .2, .3 etc... for how many cards you have in the system. To change your clock rates: Set your core clock to 900MHz and your memory clock to 1000MHz on all cards. Change according to your desire. aticonfig --od-setclocks=900,1000 --adapter=allTo set for a particular card, change --adapter=all to the adapter number you want to change. That should take care of just about everything you need to do to mine in a Bitcoin pool. |

The bitcoin server does not need to be generating coins. If you were to specify that it should be generating coins, it would be generating them on the server's CPU, which is not at all efficient. Just set up bitcoind as a server and point your miner to it.
|
|
|
|
Oh, and last time I noticed, they didn't do JNI yet, so you can't run my miner with it.
Ah, okay. Got it. |

If I where you. I'd sell 1000 BTC every month for that current prize and fuck my day job. I'd happily pay taxes on that and life my life for the next 31 years in peace and riches..
This sounds terrible. I would pay whatever was required to have all my needs met for bitcoin directly. I bet it would be easy and hardly cost extra in about 3 months. To never touch another dollar would be sweet. +1 Bitcoin is not a get-rich-quick scheme. The end goal of bitcoin is to create a self-contained economy. |

Man, I'm glad you're taking your FPGA idea in this direction. I was worried you might go rogue and screw us all over or something.
I have a bachelor's degree in computer science. I would definitely be interested in helping write software for this. Pretty much useless when it comes to hardware, though I'm interested in learning as much as I can.

Now the odds for me getting one block is pretty small.
LOL.  As for all of you who have been freaking out about the jump, perhaps it wasn't as much of a jump as you thought: http://forum.bitcoin.org/index.php?topic=7725.msg128908#msg128908Looks like someone was able to predict the current number to within 0.36% about ten days ago. Although I admit I'm a little fuzzy about how difficulty adjustment works. If the algorithm takes the average time over the whole two week period, then it might have been that cypherf0x's cluster didn't come online soon enough to greatly affect the overall average. If that's the case, we may be seeing an even bigger rise another two weeks from now, one that violates the approximate 2.5% rate of growth we've been seeing so far. |
