This should be able to get your location from your browser like google maps etc can. I don't think my swedish zip-code will do much good.

warpi, can you record the history?
It would be possible to construct three-dimensional "trench" and see how a change offers. (Many of us believe that there is collusion and rate changes synchronously)
That would be awesome! |

I've written a primitive trading bot for MtGox. It can earn money in some circumstances - but in general it fails probably because of the competition of other bots. I understand that knowledge in this field is mostly kept secret - but sum of it must be public. Any links? I am also open for cooperation.
By the way, it is fscking addictive. Maybe I should open source it? I have the feeling that playing this game can be like FarmVille for geeks and can generate tons of publicity for bitcoin.
I am writing a bot for trading stocks, and I would never open-source that. Defeats the purpose imo =) There are actually some papers about trading and machine learning. I think a problem is if everyone runs a bot with the same algo, it will affect the results... and not work so well any more. Some adaptability and also originality is required. |

Helicopters (including multirotors) are not efficient at all. Same thing with real helis versus airplanes. Helicopters' range is fairly limited.
Although its probably still good enough for, say, manhattan.
Other than that, building good robots/rc stuff generally takes a _lot_ of time and a _lot_ of money. I don't see this idea happening for a couple of years at least.

67 incoming at the moment, and thats fairly normal.

Unfortunately, I can't switch to prodnet, because Android apps only got 4 MB of heap memory and that's not enough for the blockchain. I'm fairly sure 16MB heap has been standard for some time. I think my magic had that, and its an old phone. Also, if youre on cyanogenmod you can change the heapsize. |

It might be nice to add OP_WHIRLPOOL etc. to Script to ease a switch if one is ever needed.
Well, it sounds like a flag would be nice in this situation. Value 0 = "classic" hash Value 1 = sha512 Value 2 = whirlpool What if the network could theoretically accept different hashes (and perhaps different pub/priv keylengths ?) Sounds like a bad idea to me. Instead if 1 security problem, you have 3. Security will be always as strong as the weakest hashing method you can choose. Correct, the right way is to force inclusion of more than one hash. |

Best site for bitcoin graphs, thats for sure. I never used it before, but I will know!

Uh, 500w nominal. Good luck. "Oh shit, another cloud, box shut down!"  |

It seems to me from what I have learned so far about bitcoin that all of this should probably be done for Alice by thispackageisnotforlaunderingmoney software installed on her own machine, as I get the impression nothing in the blockchain records indicates whether more than one machine wrote any part of the block chain. This doesn't matter, you have to consider the fact that "owning" a whole lot of the network connections is fairly easy, and given that you can add that info yourself depending on where in the network the protocol commands came from. Might work if you do it yourself, split into multiple actions, every action done via Tor and different end-points. |

You do know that SELLING _after_ a crash would be extremely stupid? |

I laughed out loud!
You should post this on witcoin, I guess, and maybe expand on it.

I feel most scaling-related discussions seems to gravitate toward the network needing "supernodes", maybe not in name but in practice anyway. Supernodes very efficiently spread data across the network, for one, and they make it much less likely we will have too many hops.
The problem with these of course are trust, its easy to control the network if you control too much cpu-power or connections.

A client that connects up, subscribes, and then gets updates as they happen might be an easier start.
Connects via another port? Or would you teach bitcoin's minimal http implementation to keep the connection open? (and service multiple connections at once) I've got a use case (google App Engine) where a persistent connection to bitcoin isn't possible (App Engine apps can fetch URLs, and can act as 'web hooks', but can't just open a socket and listen). There is channel API: http://code.google.com/appengine/docs/python/channel/overview.html |

Verifying an ECDSA signature takes about 3 ms. Let's say the typical transaction has 2 inputs. Each transaction is verified twice, once alone and once in a block. That's 12 ms per node, times 10000 nodes for 120 cpu-seconds, aka 2 cpu-minutes or 1/30 cpu-hour. I'm going to say a computer draws 300W @ $0.10/kWh for electricity, for $0.03 per cpu-hour. YMMV. That makes $0.001 for cpu costs, a tenth of a cent, which appears to dominate.
3 ms sounds like a long time, on what hardware is that? |

Sure it's a memory leak? Could be a sort of garbage collection, just like the JVM.
Yes, could be. Might be a chrome bug I guess, but as the page actually crashes I am a bit suspicious. |

This thing has an awesome memory leak in chrome 10:  Goes for a few minutes then goes "ooh, snap!" |

I'd like to book two or three girls in order to celebrate the bitcoin parity. They have to be tall, caucasian and good looking. If they can bring cocaine, I buy that too. Girls have to stay the night and accept anal, ass-to-mouth, gaging, deepthroat and spanking. I'm sado so at least one of them has to be maso. If the others accept to be beaten, it's good but I'm ok if they refuse that. Yet all of them have to accept at least a few strong slaps in the face.
Please PM me photos and fares.
I will pay for a video of this meetup! |

I think the way this guy explains how Bitcoin works is VERY clear. If possible we should put this on youtube.
Thanks Bruce for sharing the link!
Im not so sure it was "very clear", but with some editing this could become a good technical video-introduction to bitcoin. |
