Hi, Just to be sure: what program are you running exactly? The one there: http://www.bitcoin.org ? If yes, that's not a miner, that's "just" the program to handle your wallet. |

Part of the problem with a currency that is suspected to gain value is that people are less willing to spend it. I think people would be more willing to accept it as a currency if it made some attempt to maintain a constant value instead of an increasing value. Yeah, that's actually a major issue IMO, and the worst part of that problem is: it seems that a lot of people very involved in BTC think that this on the contrary is a strength. This can even be read it the FAQ (not with those words, but that seems to be the idea): "don't worry, there won't be inflation but rather deflation, it's a great thing". No, it's not. If BTCs keep gaining value, clinging to your BTCs instead of spending them is actually a profitable investment. Since I don't think anyone will put all their money or even the majority of their money into BTC, noone will be forced to spend them, ie it's possible that everyone just cling to their BTCs. How useful is a currency if noone is willing to spend it? Real world money keeps losing 1-2% value every year, and when you think about it, that's definitely a strong incentive to either spend it or invest it, and not to keep it dormant in your safe like you'd do with, say... gold? Which leaves to my next question: are you guys willing to create another currency or to create another gold?If you're willing to create another gold, then there's a problem: real gold actually has an intrinsic value, ie it is required to build some electronics components, and lots of people women  want jewelry made of gold. The same is not true of BTCs. BTCs serve no component-building purpose nor decorative purpose. If all the BTCs of the world end up in a forgotten stash on a forgotten hard drive, noone will miss it. At best maybe someone will create another BTC-like e-currency. I'm actually mining at the moment, but have no plan of selling or spending my BTCs any time soon... |

By the way, anybody have any suggestion on how high you can push the temp on the 6950's? I think that for pretty much any GPU you can flirt with the 100°C. Anyway, as long as you leave the fan autoregulated you'll know you're not at the max temp as long as the fan isn't at 100%. Not sure how much it harms the card longevity, though. |

Ok, well I went ahead and deleted all those log files except for the last one, and everything seems fine after running the client for like an hour.

Simply deleting them is fine, just make sure you exit the client first. Last time I did that (on my empty wallet) the bitcoin client kept crashing when I relaunched it (ran for a few minutes then crash), and I eventually had to wipe out the whole blockchain and start over. Are you really sure I can delete all those files, or do you mean the old ones that haven't been modified for at least a week? |

About 550 Mhash/s with 2 underclocked Radeon 5870. Slow, but very silent though  |

I recently built a computer with 2 Radeon 5870. Strangely enough, the second one, which has no monitor plugged-in, can only be used for mining when Crossfire is ENABLED (otherwise even the Catalyst control center doesn't see it; only AMD GPU clock tool does). I'm using cgminer and it works great on them, as if they were not in Crossfire... (the only limitation is that it uses at 100% one CPU core per GPU)

I agree with the various problem already debated. I think there are also some other concerns (or rather, some questions), not just for mainstream acceptance but also for "computer people" acceptance. Maybe they are trivial and I shouldn't worry about those, but still I didn't find any crystal-clear answer to those: 1) Who or what resets the mining difficulty? Looks like I'm not the only wondering this. As far as I understood the difficulty is adjusted given the hashrate power of the network, so adjusting it needs a measure of blockcount (every client has it, afaik) and time (potentially different from a client to another - needs some kind of a central authority - who is this?) 2) Is there someone or a few people controlling the core of the network? If no, then why does it seem so hard to set up a test network (I think I read about that in some developer/debugging thread)? If yes, who? and how do we know this won't stop running at some point? NB: I know every Bitcoin ad I see says "no central authority", but they always forget to explain (even briefly) how it is possible to achieve this... 3) As far as I understood: blocks and all transactions are stored in the blockchain, which is duplicated on all clients. What happens when/if there's a mass adoption and, say, 100M transactions a day (yeah, not likely to happen any time soon, but that's what they said about year 2000 when they were happily storing dates in 2 digits in the 1980s). More generally, will that thing scale (very) well? Sorry again if this looks like newbie questions (but hey that's the newbie section after all ), but I really think clear answers to those may help to convince more tech-aware people to try BTC (or not ^^), which is a first step before going for mainstream acceptance. |

I'm at Deepbit too, it just seems that the pool has been quite unlucky during the last couple of days. Hashrate isn't really much lower, went from something like 5.7Th/s to 5.3Th/s.

Well, yeah, restarting the client removes a few files, but some (for a total of around 80 MB) are staying. The most weird thing is that the bitcoin client doesn't even seem to use them anymore (their last modification dates range from 1 month to a few days).

Hi, I recently noticed that the log files contained in the database (%appdata%/Bitcoin/database) folder don't seem to get purged properly. The only things I found about this is https://en.bitcoin.it/wiki/Data_directory#Subdirectories and https://bitcointalk.org/index.php?topic=20298.0 . The strange thing is that I'm regularly switching between 2 wallets, every time switching the whole content of %appdata%/Bitcoin, and both don't have the same amount of files in %appdata%/Bitcoin/database. Is there any way to purge that folder? I mean, apart from wiping everything but the wallet? Not that that database folder is huge (yet), but I'm worrying about it growing indefinitely... Thanks |

1) massively underclock the memory on your GPU cards to between 250-300 .. (you should be doing this anyway to save power) Unless taken to absolute extremes, this will not impact mining performance. It will, however, impact gaming performance if this is a dual-use rig.
2) If noise is a bigger concern than performance, underclock the cores on your GPU cards. This will also save power, and allow you to lower the voltage on the card, saving more power. Underclocking is indeed the way to go IMO, if you don't want to use watercooling. That's what I did on my latest rig: I have 2 Radeon 5870. The bottom one underclocked at 750MHz (core) / 300 MHz (memory), the top one, which isn't as well ventilated, is currently at 550/300. I hope to increase those when room temperature gets lower... You could also flash the graphic card BIOS to modify the fan speed / temperature curve ; unfortunately on my card this wasn't an option. |
