Are you sure that's enough? I don't suddenly want to pay back for misunderstanding.
I mean, a customer could use 10minute e-mail, Tails Live CD or even laundries and if they do so, I can't prove who they are -- wouldn't they disapprove my income then?
No. Shops don't ask for your ID when you buy soda. They record the purchase on a log and then they report it as is: "sold i soda at 12:34 AM for 1 EUR". They don't need more proof than that. Tax collectors usually have problems with people not reporting income, not with people reporting it  . Edit: Of course, some economic activities will require more data than this. Check you local laws. |

Thanks a lot, much appreciated; that actually cleared a lot for me, but if there would be any question about my income, how can I prove where I got it from?
A printout of the logs of your Bitcoin client or even some screenshots of the Received page on the standard desktop client should be enough. You can even alias the receiving addresses to some useful label, like client name, email address. |

Not mentioning that exchange or online storage of bitcoins would require to be a bank, which involves a lot of fees and time (can take up to 5 years to create one).
Not true. Where I live (Bucharest/Romania) there are dedicated exchange houses which are not banks. You go in, give cash, get cash in another currency. I've seen these in other countries. These are regulated in the EU, and you need a licence to operate one. Moreover, Romania is a recent addition to the EU, so it is possible that the relevant legislation is just being implemented (accession countries had a grace period to implement legislation). It's possible, I don't know the legal status of these. But I am pretty sure that they don't need to follow the same rules, don't need to pay the same fees and most definitely will not take years to create one. The point of my comment was that I don't believe the issue to be as bad as MagicalTux implied. There are solutions to open an exchange other than become a bank. There are also other countries other than France in the SEPA zone. Even Romania, why not? |

Either both parties trust eachother, or they use an escrow service for a small fee. Search the forums, you will find some.

Just so you can exclude the driver being too old, I suggest you go to this thread[1] and get LinuxCoin. You have there a video tutorial and if you read on you'll see exactly how to create a USB disk from the ISO file (you can do it in Windows pretty easy). I can vouch that my 5830 xtreme can be overclocked to 1020 without BIOS editing, using LinuxCoin and the commands that I pasted. If it still doesn't work, then it's hardware related and you might want to edit your BIOS. 1. http://bitcointalk.org/index.php?topic=7374.0 |

Other three simple scenarios that I experienced myself with the current broken banking systems:
* Friend wants to buy some thing online - only 1 left in stock. Friend asked me for some money until his next paycheck - we were not in the same town then, so no cash option for us. Since it was a saturday, he could not buy the item then and had to pay +30% a week later.
* I wanted to send some money to a friend in another country. The fees? 30 EUR + 2%. Time? 2+ working days.
* Since I'm from Romania, my debit cards were not accepted online in a lot of places, so I had to go get a "real" credit card - with more than 4 times the fees.
And so on...

Ah, then my answer would be "I don't think so". I had to edit the BIOS on the first card I bought, then I upgraded the fglrx driver and changed motherboards, then I bought the second card and I simply forgot to edit its BIOS. And I could overclock it just fine, even though 'aticonfig --odgc' says its upper limit is 900 MHz. I'm too lazy to burn the original BIOS to card 1 to see if I can overclock it with the original limit on, I am convinced it's just a driver thing.

@futonrevelation, if you're inexperienced with the terminal, I would suggest you don't use it to do sensitive stuff, that might result in losing your wallet file. You should use the graphical interface. Since you said you're using Ubuntu 11.04, I suppose you're using the Unity interface (the one with the square buttons on the left side of the screen) ? If so, open your home folder, it looks like a folder with a home on it  . Go to View > Show hidden files (or press CTRL-H) and you should see a bunch more folders than before, a lot of them starting with a dot. These are hidden files, and ".bitcoin" will be there too. Open it and copy and paste wallet.dat to another folder (your Desktop, for example, or a USB stick, which is a better idea. You should do this simple backup every week at least, if not every day). You can then delete the corrupt files and reload the client. Good luck! |

I don't know if all Sapphire 5830 Extreme are created equal.
They are not. I have two, one can be overclocked up to 1060 MHz, the other hangs at 1030. Same PCI-E socket, same miner and settings, same temperature. But I do believe that 1000 is possible with any card. |

This works for me: aticonfig --adapter=1 --pplib-cmd "set fanspeed 0 100"
aticonfig --adapter=1 --od-enable
aticonfig --adapter=1 --odsc=1040,325
aticonfig --adapter=1 --odcc For some magic combination of drivers/cards, you can set the frequencies over the BIOS maximums, or you can edit the card BIOS to allow more overclocking. Make sure your PSU can give out enough juice to the cards. Also, make sure the MB is up to it - for example, one of my MBs has a dedicated power connector for the second PCI-E. Without extra power to it, the second GPU would lock up. It might be your situation, too. |

I'm not going to discuss the price, anyone can value his services at whatever price he wants and it's the customer's duty to do some research before buying. I am, however, going to kindly ask OP to remove "encrypted" from the offer. It's uselees, it's manipulative, it's dangerous to the clients' data. Why? I wrote some thoughts about it (sorry for promoting my blog, but I'm too lazy to copy-paste): http://blog.mybox.ro/2011/08/09/why-server-side-encryption-is-both-useless-and-dangerous/And for OP, I have a simple question: where are the decryption keys stored exactly? (And I do mean *exactly*. I would expect the answer to be "a file". A file in OPs control, and in OPs local police/other structures reach. Which is, IMHO, a lot more dangerous than not having encryption in the first place). Again, I'm not trying to bash anyone, I just think that buying "encrypted servers" is a very-very-very bad idea. |

Second, you don't seem to have much experience with datacenters.
If you did, you'd realize that plonking a GPU in a rackmounted
server is slightly more complicated than doing it on the gaming
PC sitting under your desk.
I will also add to this that I pay a fixed amount for colocating my servers in a datacenter here in Bucharest. I don't pay for electricity, I don't pay for traffic. So running a CPU miner on low priority as to not interact with the normal services on those servers makes perfect sense for me. As for GPU mining, as soon as someone fits a 6990 in a 1U server, let me know, I'm very interested |

I mean, won't the slower clock speed cancel out the gains?
Correct, but if you get the same hashrate al lower clock speed, you save some power. This saves money, heat, and is considered safer in the long run for your system. |

Actually, I would suspect it to be in the new phatk2 kernel. There was a similar leak in the original phatk2 kernel (which was actually much faster before they fixed it) and they had to revert some changes to fix it. It's probable that the source used for cgminer was of the problematic version and a similar reversion will need to be made for it as well.
No, I was running 1.5.5 with the old kernel. As Con said, if I still get a lot of crashes I will decrease intensity. But it appears that's not the case with 1.5.6 - no crashes, no hardware errors, which is consistent with my results with phoenix-1.5 + phatk-2.2. I might even try to increase the frequency a little and see if hardware errors went away at higher freqs too (also expected). The other 2 notable differences are increased hashrate (hooray) and +2 degrees C heat per board (booo) - also expected. |

Returning with the ps snapshots I promised. I only left it running for a few hours, because I wanted to upgrade to 1.5.6. The lines below are done at 10 minutes each, with 'ps aux'. I only edited my username and password. The full command line is: ./cgminer -o http://pit.deepbit.net:8332 -u XXXXX -p XXXXX -o http://uscentral.btcguild.com:8332 -u XXXXX -p XXXXX -o http://api2.bitcoin.cz:8332 -u XXXXX -p XXXXX --submit-stale -t 0 -Q 4 -g 2 -I 10 -k phatk -v 2 -w 256 -d 0 -d 1 I think it's not enough data to draw a conclusion, but I have the suspicion that there is a memory leak somewhere, most likely in the dead gpu detection/restart code. The jumps in allocated memory are after such an event. I already started to get ps snapshots of 1.5.6 (I used the same -I option to make the gpus crash often), let me know if you need any other data: root 16885 1.3 10.8 382588 110448 pts/1 Sl+ 05:26 0:35 ./cgminer -o http://pit.deepbit.net:8332 -u XXXXXX -p XXXXXX

Yes indeed, that's what I've spent weeks working on to get right. To restart it if it can only. The 5 minutes was a nominal choice based on the theory that if it gets sick, giving it a few minutes to cool down will make it more likely to respond. Note that if it gets sick a LOT, you may benefit from decreasing the intensity and sacrificing a few MH just to get a more stable throughput (eg -I 7 instead of  . Only happened twice in 4-5 hours, so I think I'm ok. It's 5 minutes then... I need patience... or a command line switch? Edit: confirmed, it restarts after 5 minutes. An option would be nice - my GPUs cool down way faster than that, and I think that's the case with most miners, most of them have extra fans and cooling. |

I might have detected a memory leak in 1.5.5. After ~8 hours of work, cgminer got oom-killed. I restarted the process and I'm taking ps snapshots every 10 minutes to see if I'm right. I'll be back . |
|

Do 'SICK' GPU's ever get restarted? Sometimes I get 'Thread 3 idle for more than 60 seconds, GPU 1 declared SICK!' and mining stops on that GPU. If I restart it manually, work resumes just fine, so I guess it cgminer should try to restart the GPU automagically? I waited 3 minutes and the GPU was not restarted, maybe there is a bigger timeout?
Edit: When it gets marked as DEAD, it does get restarted immediately.

There's a lot more differences than just the changes to the parameters: IXCoin is nothing new, it can use BTC as currency for exchange, whereas bitcoin has to use fiat currencies to get value in.
Either I don't correctly understand what you're saying (English is not my mother tongue) or you are wrong. Who said you can't exchange ixcoin to fiat currencies? The only people defending this are the people who signed up for bounties as moderators etc...
I have yet to see a 'regular' user recommend ixcoin to anyone
I don't recommend it to anyone. I don't use it myself, I actually only found out about it this morning (I'm a BTC newbie too). But I still would like to see how this experiment will end - reaching the coins limit and inflation/deflation issues that will appear. This is something that we will not see with BitCoin any time soon. Before I decide to base my small IT business on BitCoin, it would help me to know what would happen. I started to consider ixcoin as BitCoin or steroids |
