i can think of 2 popular females bitcoiners off the top of my head, that porn lady that owned vageta and msbitcoin i think her name is with the tattoo.
females will use it when they find out about it, and frankly most here are male because the tech category is own by most all men, with some women every once and a while. and you find most of them playing games, mostly in the mmo category. this is probably one of the female desolate places on the internet that allows females in freely.

No they don't. BankBitcoin transfers don't involve nearly as many any draconian and arbitrary restrictions as like Paypal. They also get abused for fraud and other criminal activity, but banks don't police their costumers like paypal does. Banks leave that job to, you know, the police, and cooperate with the police if and only if required to do so.

ebay is down around .95 and 2.73% right now for the past day

every paypal account i have ever had was always locked, for no reason, so i never used them to begin with because it simply stupid policies. http://twitpic.com/5ws6gs lol |

It is my understanding that the nodes save multiple copies of the block-chain in case of a split or one of the block-chains becomes the "longest" one. I have had a test-node running since June 9, 2011 (0.2.22 and 0.2.23) for a total of 55 days. It ran out of disk space today; consuming 5.8 GB. That works out to 105MB per day. Disk usage dropped to 4.9GB when the client exited. The client had 125 connections during peak times.
I have no idea about the test network, but my entire %appdata%\bitcoin dir has never went over 800mb, yet, but i would assume it will be by the end of next month at most. |

As a trader I'm happy to accept bitcoins, but no one has them so few people buy in this way.
I want it the other way round - ie a buyer can pay with their credit card, bank transfer etc and I receive payment in bitcoins (which I can easily convert to cash whenever I like).
This makes international trade much easier as the buyer does not need to be aware that transfer of value occurred in bitcoins.
There could be an open source payment checkout system that links to to the exchange of your choice in your own country, you press pay and the money is immediately converted to bitcoins in the local exchange and sent to the seller anywhere in the world. If the seller's exchange is connected to this system it could automatically convert the bitcoins to cash in the local currency (if the seller prefers cash).
All the exchanges around the world could function like a distributed paypal without having to open branches in every country.
No single entity needs to open it's own branch in every country - each exchange would be responsible for dealing with local legislation.
I like that idea, but the best solution is to pay in bitcoin everywhere, and get paid in bitcoin. then you never have to exchange in and out of USD. |

if you only have 8 connections total, it means that you do not have the port forwarded, and thus will not upload blocks, at least AFAIK. this also means that the only data sent/received is blocks coming in only and transactions coming in, and yours going out.

 Just what i see in the USD<->BC exchange, mostly getting USD in and out of exchanges. |

What difference would it make, EVERYONE would be wasting 10%, just like everyone is wasting 1% now. so why would it matter. if it bothers you that the network would be less secure, then wait 10 minutes or 2 blocks or however long you like.

Given constant latency, waste increases EXPONENTIALLY as block generation time decreases until waste is greater than effect. Splitting DOES matter. Forget about the general users. Focus on the MINERS and the problems of latency and splitting will become clear.
Suppose splits represent 0.5% of blocks today and wasted cycles during latency 1%. If you divide the block generation time in half to 5 minutes, waste become 3%. 2:30 minutes 6%, 1:15 minutes 12%, 37.5 seconds 24%, 20 second blocks 50% waste, 10 second blocks 100% wasted cycles. The numbers might be off, but that's the general gist of the problem.
Now does a user care about waste? No not directly. Does he need confirmations? Not in most cases. Does the network care about waste? Absolutely. Does waste make the network less robust and insecure? YES.
your throwing in a bunch of irrelevant information, nobody said anything about blocks more often than every 2 minutes. i doubt it would ever go below 5. i even doubt it ever gets changed to begin with. you also don't take into account for newer network equipment that would increase data throughput and lower overall latency. |

Absolutely! Just ask Vegetta (or whatever he changed his name to in probable disgrace) about how well bitcams is coming along. Its a great example of porn and bitcoin joining forces!
off topic, but i think most of the bitcoin community have a similar opinion. |

Can you say more about compressing the data? How could this be accomplished in a transparent way?
I understand that there is a maximum number of transactions that can be included in a single block. Do we know how much disk space a maxed-out block like this will consume?
You state that 16 gigs should should be good for 2 years worth of block chain data. Is this a wild-ass guess or based on some reasonable assumptions? If the estimate is based on some assumptions, would you please share the data you used in your calculations?
so far bitcoin has been out for around 30 months and has only just reached about 400mb, 500 if you count indexes. thats 2.5 years. the past 100,000 blocks have an average size of 4244b the past 50000 7900b 25000 13558b 10000 22871b 5000 24994b 1000 23705b 500 23170b you can see that it doubles very roughly every 40000-60000 blocks. but this figure could very easily not work depending on bitcoin growth or death. so the average a year from now would be 40000b, so lets just assume from now on the size per block is 40000b, 40000*6*24*365 now double 40000 80000*6*24*365 add get 6,307,200,000 i don't know if these figures are bits or bytes, but ill assume bytes. 5.87 gigabytes, assuming worst case scenarios. this means i used numbers that would exist at the end of the, at the beginning. so mathematically the numbers can not be higher than this. again these numbers are probably wrong because of human behavior, my self and others, but it also seems to look like Moore's law a bit, exept the numbers are doubling sooner than every 18 months. i got the data from block explorer btw |

make it a tor hidden service. that way you dont know them, and they dont know you, nobody knows anybody.

not really a "store" but its still VERY VERY good news. too bad i live in st Louis.  |

the blockchain right now is not 600mb, its more like 400, excluding the index files. and that can be compressed to at least 80% of the original size. and. 16 gigs should be good for a linux install and 2 more years worth of blockchain worst case. |

block chain splitting is irreverent AFAIK. this is because only the longest chain will survive. and if you are connected to a decent amount of nodes, then your transaction may very well make it into both chains so it would not matter. and as far as wasting hashing power goes, it does not matter, so what you wasted 30 seconds. that's only 10% of the total time, and nearly everyone else would be in the same boat. and 30 seconds is a large exaggeration. and as said before, we could make little miniature networks, where miners specifically make a point to connect to other miners, in addition to normal not mining nodes. in response to what was said earlier about this, i say that there be multiple lists where miners can submit their ip address. Another solution to make the network more redundant would to create a new protocol. this would include a new type of node called an exchange node. it tells who to connect to who, to be the most efficient. you obviously would want to make it open source, and only connect to trusted exchange nodes. here is an image i made of a network with exchange nodes, it does not show much, i mostly made it for fun  |

just a tip for you guys that use them, if you are noobs are vector graphics, size and edit them to your needs, then export to PNG, stay away from using them directly inside webpages and such, at least for the time being.

So i can assume that truecrypt does not have any functionality built in to import a file with random data.
