Some weeks ago I started looking on the last bitcoind sources; I would like to understand the progress on the design since the paper. The oldest version available is bitcoin-0.3.24, but that's not so old..
Does anyone still have it? why it was removed from SF?
Thanks!

I don't know why it happens but if I need to bootstrap a new node I start it up with the connect= argument to only download from a single server, ideally one on the same LAN.
oh you remind me that I was going to suggest some api call to look up for other peers so you can find the best one/faster for your host (for geographical reasons) |

Synchronize with the network get slower (almost "exponentially") when you are reaching the end of the blockchain, and for some users it get stuck at some point. On my case I got like 1 block per minute or more, and I was around 90% for 2 days. But then I realized that if I restarted the client it begun to download the chain again at a rate of ~3 blocks per second, but then after a couple of minutes it was getting slower and slower. It looked like there was an inverse relationship between the number of peers connected (~10) to my client and the syncing speed, so I tried starting bitcoin-qt with maxconnections=2 and the speed kept at ~2 blocks per second, with 4 connections it was like 3, but then with 5 it was slower... So, I could finally synchronize with the network in a couple of hours using maxconnections=4  I do have UPnP on my router, and (eg) BitTorrent works just fine. could somebody explain this behaviour?  |

Hmm, that begs the question: why run the instances yourself in the first place? Why not simply ask a bunch of clients about their opinion about the latest block (height and hash or whatever) via the protocol itself? Would that also be workable or does that approach have a problem?
could be something like this be implemented on the client to measure a potential fork? |

Yes, you can surmise exactly that. IT IS MY JOB. I AM DOING MY JOB.
Guess who isn't, and guess what that makes them.
Yeah, I know what you mean... your website have been down for weeks now  |

the problem with this "crisis" is the moment..

Seriously, you made TWO major changes at once (block size and database type) at once... And deployed in production and partially only (because not all people upgraded). The problem is older than you think. 0.8 is fine (at least with regards to the current problem). 0.7 had a bug in it and consequently is not capable of handling what it's supposed to be able to handle. incompatibility between versions should be called (at least) an issue imho... |

I don't think it's all just habit or psychology. If you say 49.72 you need some specific reason for the precision, just like if you said 50.00, but no one (outside of mytho-chartalists) claims that precision so they use even numbers to indicate that it's just a rough guess.
and what about asks/bids or spot rates? I think (baseless beliefs  ) that people are more inclined to type eg 100 than 97 |

I find a bit funny when people put imaginary barriers to the price of btc (*) on their speculations. Why people say $50 instead of 53 or 51.3 or even sqrt(3210)? It's like they find the 0 positioned into the least significant digit as something relevant... Maybe some people says 50 as an approximation, but what would you put in your ask price: $97 or $100? I would love to see how many people choose "nice numbers" (like 100) instead of primary number (97) What could happen if we all start using any other numerical system, like hexadecimal? I don't think we are going to say "Hey, it will break at 0x3C, I'm sure!". And what the number of digits would mean? it would be less accurate than now?  Does anybody knnows if there is there any study about this kind of stuff? cheers! EDIT: (*) to be fair this happen on any market/society, not only bitcoin EDIT 2: I found a some research's about this topic: http://mro.massey.ac.nz/bitstream/handle/10179/2695/02_whole.pdf?sequence=1 (a mbs thesis) http://www.cepr.org/pubs/Bulletin/meets/1180.htmhttps://en.wikipedia.org/wiki/Psychological_pricing |

I totally uninstalled and deleted everything and installed it all again - it synced OK after about 10 hours
- the thing is I was expecting some money and not I have a different address in the wallet - I have the old address that the money belongs to but not its key - is my money lost or can I still get at my money somehow.
If you deleted your previous wallet.dat, and you had no backups, and you cannot recover it via recovery tools, then any money that had been deposited in any of the keys of that wallet is lost for good. You should never delete a wallet.dat which has coins in it. THIS, you should stop using your computer/hdd right now and try to use a recovery tool to get back your wallet file. good luck! |

Not sure about this but I think that Avalon's ASICs are already shipped, so if you don't trust BFL you could buy from Avalon (but yeah: it's really expensive) btw there are a lot of people saying something like "if they could mine 100 times faster with their processors why would they sell them, it must be a scam!!1", but hey: how much time do you need with the fastest miner to obtain enough blocks to make back your investment, and how many miners would you need to get rich? you'll have to do a really big investment. And also you should trust that the value of bitcoin will at least be stay stable until you get all the blocks... but I actually don't know anything about BFL, this is just my vision about selling miners |

IMO it's really difficult (probably impossible) to predict that Bitcoin will not crash next month, but I think is very plausible that in a period of less than two years the price will be, at least, the same as now. So, if you don't mind holding onto your bitcoins for a while the risk to lose your money is low. I think the only thing that could stop Bitcoin would be a law against distributed crypto-currencies in USA, Europe, China, Japan and Russia...
cheers

I think I read that their nameserver was cracked (provably dns cache poisoning) last weekend... if you access to http://bitinstant.com it redirect to https, and they have a certificate from GeoTrust. But the crackers could keep you on their server (with a fake BitInstant website) without redirecting to https obviously. You should always have to connect using https so your browser can verify the certificate (or wait for DNSSEC ). |
