Oh dear, how did that happen?  It was missing the "i" on the end, fixed.

P.S.  You can look up a partial address at http://blockexplorer.com to determine the full address, if that address has been used before.  That's what I just did.

No probs.  Post with your address, and send 0.02 to the address in my sig.  I'd be happy to send first.

If a satoshi (i.e. smallest unit of divisibility) were valued at one cent, then the maximum valuation of the entire Bitcoin economy would be $21 trillion.  Even if 90% of bitcoins were to be lost, that would still be $2 trillion.

What this means is, even in the extreme scenario of 90% of bitcoins being lost, the bitcoin economy could still grow to about 350,000x its current size before the value of the smallest unit would be more than the current value of a cent.  (3,500,000x if no coins are lost.)  And it's feasible to have an economy where the smallest possible direct transaction is more than a cent (auxiliary or intermediary currencies can be used for smaller transactions) - the US economy wouldn't collapse if they stopped minting pennies, after all.

Do you mean "meta"?  Should we report typos and such here too?

The unknown identity of satoshi and theories about who or what he is - is a meme ?
I agree that this has acquired meme status - especially people pretending to know Satoshi and offering outlandish explanations for his absence.  There's some pretty funny stuff along these lines out there.   Tongue

其实,我没看过孔子学院。我的大学有个中文系(还有法文系、德文系、俄文系等)。我的专业是语言学,专注是中文,而且我有时候上电脑学和数学的课。

因为我喜欢学电脑学,学得非常好,所以谷歌给我在西雅图十四个星期的实习。Cheesy 实习结束以后,我要回去大学。

哦!链接没什么问题。关于英语视频,叙述者的发音非常好,但他的节奏和用语奇怪一点。
我以为你发帖了收费的视频。现在人家能免费地看这个。

你去过上饶师范学院吗?那儿的英语老师都是我的朋友。

现在我和我父母住在加拿大温哥华。我不久会搬家到美国西雅图上实习(哥哥住在西雅图)。我的大学离洛杉矶不远,我今年秋天会回去那儿。

Today's now the single biggest trading day yet (in USD).  Fascinating to watch...

当我去三清山时,拍了四百多照片。正是非常漂亮,使我惊叹的地方!

我认为我挺好地读写中文,可是标准比自然好,而我的说话本领和听本领都是烂的。(再说,词典让写作是不太难的。)
我老是告诉我的学生:“你必须每天讲英语!要不然,你会听不懂,说得不流利,写得不自然。”
各种语言都这样,以此我该更多常练习中文。

And it's miners who have fee policies, not "clients", as in general purpose clients.
Policy, scheme, convention, whatever you want to call it - I mean clients should have (as they already do) some built-in fee-determining algorithm.  I don't think it needs to be any more complicated than a preference for fee/kb in a GUI client (and in a CLI client this could be passed as an argument).  However you do it, this makes it possible to do a "fee pre-calculation" as described above.  All this really is is a pre-calculation of the size of the outgoing transaction.
152  Bitcoin / Development & Technical Discussion / Re: A bug in the bitсoind who steals your money. on: April 15, 2011, 09:00:59 AM
I think, there is a need for fee pre-calculation API call.

I disagree. There's no way to "pre-calculate" fees as miners are free to set the fee policy they want. This standard policy that's being followed by most miners is a set of arbitrary rules that were coded into the standard client, but these are not carved on stone or anything. Miners are free to come up with their own policies.

Actually, I don't even think the standard client should have this fee policy or even a miner. It should limit itself in defining what is a valid block and what is not.
But presumably the client will have some fee policy, unless the user is expected to manually guess at a good fee for every transaction they make.  Thus, it ought to be possible to calculate in advance what the fee would be, in accordance with whatever policy the client uses.

I was originally going to put "office supplies", but I realized that already a lot of the trading going on in BTC is for a more general category of things required to run a business - advertising, web hosting, logo design, etc.  Hard to sum all that up in just a few words.
154  Economy / Trading Discussion / Re: I wish I could buy X with bitcoin... on: April 15, 2011, 08:50:32 AM
How about "Stationery / Business Needs"?  That's the first one to come to mind for me, since I'm thinking about starting a small bitcoin-for-cash business when I go back to university.
155  Bitcoin / Bitcoin Discussion / Re: Double Spending Proof of Concept on: April 14, 2011, 11:29:34 PM
Does the client alert you that a transaction has been denied? Or does it just say " 0/unconfirmed " forever?

That might be a future feature: http://bitcointalk.org/index.php?topic=5758.msg84785#msg84785
(i.e. if your transaction is not processed within 24 hours, you would know it has been "rejected")
156  Bitcoin / Mining / Re: Bitcoin mining profitability calculator on: April 14, 2011, 05:51:43 PM
It doesn't take into account future increases in BTC value, either (which could offset this).  There are many variables, but I for one think this is a useful tool for demonstrating that mining can be profitable.

Of course it is profitable (certainly if you already own hardware) but calculations without factoring difficulty increase are very misleading.

Of course it is profitable if the value of your earned BTC exceeds your hardware and electricity costs, but now we're venturing into the realm of tautology.  It's not "of course" profitable for everyone, and reading the forum, many people are skeptical it can be profitable for anyone.  Some simple math, and clearly it can.  I gather that's why this calculator was made.

I'm afraid that without factoring future increases in difficulty, this is fairly useless.

Seems like this game is pretty popular, where's all the hype come from? First one was awesome?

To put it one way, I bought the game at I think 7PM one night, started playing around 9PM, and finished the game sometime around 4AM.  I've wished so many times that I could forget all about the game and play it again to experience it with a fresh mind.  I would easily call it my favorite video game, and Portal 2 is looking like it will easily live up to the standard set by the original.

HA!  My brother came to visit me once and was wondering what all the hype was about.  We were going to play through it together, and started and finished about the same times that you did... the only catch was that there was no "we" - he got so into it that I never got a turn.  XD
160  Other / Off-topic / Facebook to be world's biggest bank on: April 13, 2011, 03:43:22 PM
http://www.techworld.com.au/article/383125/facebook_biggest_bank_by_2015/

NO.

I sure hope Bitcoin throws a wrench in the gears.

QOTD: "I think that to say 'Facebook will be the worlds largest bank' is about as accurate as saying 'Farmville will be the world's largest agricultural business'."
