Heat will shorten the lifetime of the battery, so unless you get a pretty decent speed you shouldn't use a laptop for mining.

It's easier to manage if you don't start a separate screen session for each miner. If you just type screen once, you will start a screen session. You can then start as many terminals as you like inside that session by pressing ctrl-a c to create, and ctrl-a n to switch between the terminals. Start one miner in each terminal. You can also start the miner directly to save some RAM by typing 'screen <miner command>' in a screen terminal.

cost of generating bitcoins goes up to the point that mining is no longer profitable, miners shut off their machines, fewer bitcoins for trade on Mt. Gox, scarcity makes value spike, miners turn machines back on. Unless absolutely everybody turns off their miner, the same amount of bitcoins will be mined every day. The difficulty level will just drop to adapt. |

Right but who here pays $0.80 per kilowatt-hour? I doubt anyone pays that much. I think for the majority of GPU miners the mining biz is still profitable.
You'll need a very efficient miner (probably 2x5970) to generate 1 BTC/kWh, so that's not really relevant. If you only have a single 5870 in a normal machine it will be less than half as efficient, and if you have a 4xxx ATI or Nvidia GPU it will use several times more power to generate 1 BTC. |

I do not see how prices I charge have anything to do with your (or even mine) electricity costs. I'm just assuming that you would set your prices at a level that was at least competitive with mtgox if you could. Either way, it shows that electricity cost is only a small part of the price people have to pay if they want to use a professional mining service. |

Once miners like myself grow large enough to be able to buy electricity on half hourly auctions and mining at night and/or not mining at peak hours the hobbyist are going to be driven out of the mining market and I bet it will happen by 2012-2013. You'll have to do pretty well on those auctions to drive us out. My electricity costs for mining is less than 1/6 of the price you charge. I think it'll be the other way around - those who use expensive professional services will be driven out by hobbyists who hack together cheap but mostly working solutions. Unlike most web related services, uptime and reliability is of minimal importance for mining. Hopefully it will stay that way, because it will be a lot easier to attack the network if mining becomes too centralised. On the other hand, when we have to use mining pools to get bitcoins regularly the security is already weakened. |

I'm mining with my XFX GeForce GTX 275 at a steady 59 to 61Mhash/s. I underclocked the core graphics clock down to 576MHz and the memory clock down to 775MHz, and overlocked the processor clock up to 1502 MHz.
I assume you have free electricity? Otherwise you're probably losing money. |

What kind of "no success" did you have? Any error message? You must set clockspeed for Level 2 not lower than for Level 1.
If I set a GPU speed above the ones allowed by AMD (ie 775 for 5850), the program just hangs when it's supposed to set the speed. I have only tried batch mode as I don't have a full X installation. |

I was able to lower the memory clock below the limits. After using the program, you can then change the clock by aticonfig.
Which card do you have? I've tried it on two different 5850 and a 5970 with no success. |

6950 level cards will drop to around $100.
That's fairly unlikely. 5850 came out 1.5 years ago. Except for the somewhat peculiar Sapphire 5850 Xtreme, the price never fell much below $200. |

1. If lots of people want something, the price goes up relative to what it would be if fewer people wanted said product (and vice-versa)
Higher production volume often results in lower price (as you mention in your next argument...) 2. If lots of people have and/or produce something, the price goes down relative to what it would be if fewer people supplied said product (and vice-versa).
Unless for instance the higher production volume creates a strain on neccessary resources. |

Maybe I am delusional, brainwashed or simply mistaken but asserting that it is the case won't convince me of it. You'll have to dig deeper. Unfortunately that would most likely be as useless as trying to change the mind of a communist or a deeply religious person. |

I disagree. Most people understand the broken window fallacy. This book shows them how that same reasoning applies to other things like price controls, protective tariffs, minimum wage laws, rent control, etc. If you understand the broken window fallacy, you'll be forced to agree with the other arguments presented. It's taking something that people implicitly believe and making it explicit. That's the most powerful educational tool there is.
Of course, that requires intellectual honesty. If people are just being closed-minded then your analysis holds.
If you were a communist you would say exactly the same about the arguments made in the books communists like. And of course you're now thinking "but the difference is that I'm right", just like anybody who's chosen an ideology would. |

Just an arbitrage between mining contracts and BTC/$ in progress... nothing to see here... move along people...
Buying a mining contract that values 1 BTC at about $1.27 with the current difficulty and about $1.42 at tomorrow's can hardly be called arbitrage. |

I've been thinking of making just that, but I didn't have a site to put it on.
You could also add a calculation of the break even difficulty level for the given hash rate, power consumption and bitcoin price.
