And here are German subtitles: http://hendi.name/bitcoin/What_is_Bitcoin.srt

Is it possible to upload all these subtitles to the video on Youtube?

Cool, just sent you the other 25 BTC. Thanks for your great work

Great work, thanks a lot! I've sent you the first 25 BTC

I'll give 50 BTC to the person that implements this code into jgarzik's miner. First 25 BTC when working code is released, the other 25 BTC when it's pushed into jgarzik's cpuminer git repository.

I have no direct experience with the mybitcoin SCI tools (but some years of php knowledge), but both curl and preg are php extension (nothing to do PEAR). preg is almost certainly enabled for you, curl should be also. Just try to run the script, if you get errors stating missing curl_xxxx or preg_xxxx functions then you're okay.

If you want, I can lend you a hand with setting this up. Just PM me and I'll see what I can do.

Ich habe ihn angeschrieben. Antwort: Domain wird nicht verkauft, sondern "in absehbarer Zeit mit Inhalten gefüllt, welche meine eigene deutsche Internet-Währung erklären wird und nichts mit der ausländischen Bitcoin zu tun hat."

You have to change the Makefile in utils/wxrc to include Pango-Cairo, Cairo and X11. Change line 35 to this
and Wx should compile.

Ich wäre dafür, wenn, dann das deutsche Forum *hier* als Sub-Forum einzurichten. Ich habe keine Lust noch zig weitere Benutzerkonten für Foren zu erstellen, außerdem finde ich hier, in diesem Forum, viele kompetente Leute.

I love mt_rand(1, 6) … or does it love me?

Cool idea! I've deposited some money and am waiting for an opponent to join

Cool, thanks! My first earned bitcoins

After exams I'll have a look at the bitcoin c++ source code and try to come up with the import/export.

Cool! If there's anything else you (or someone else) wants this small script to do, don't hesitate to ask

I now validate each line by checking for a valid base58 bitcoin address followed by the blocknumber. If an invalid line is found, you'll get notified with a popup. I'm not sure if this is the best notification style, I'll try later with showing the .bitkeys file and highlight wrong formatted lines, maybe that's better?

Done.

No, it's easier. You just start up your B "saving" instance once, so it creates a wallet.dat with the private key. Then, you write down your B's receiving address and backup your B wallet, and start your normal bitcoin client again. Whenever you want to save something, just create the transaction to B's receiving address. Then if the transaction is known to the network it's done. You could start your B instance like you describe to see the money you sent do yourself, but there's no need to do so. The transaction is known in the block chain, and is non-revocable. So even if you just start your B instance in 20 years, it would catch your transaction while scanning the new blocks.

Right, there's no need to be online while a transaction is done to be able to receive it.

In your wallet.dat you have your keys, plus 100 new keys. So, you have to update your B wallet every 100 transactions that you do with your B instance. If you just receive money with one of your B wallet's addresses, there's no need to backup your wallet.dat file again.
So, just create your B wallet.dat, write down the receiving address, lock the B wallet.dat in an encrypted container and don't bother with it again until you want to withdraw from your saving account.

Not much. Maybe a few MB per hour?

Yes, it's totally gone, forever! It's like burning a dollar bill and swallowing the ashes ;-)

http://hendi.name/bitcoin/ Like that?

You paste your .bitkeys file into the textarea, then for each key a QRcode is generated. Each generated code is labeld with its heading, so you can print everything on paper and then cut out individually keys. If you decode an QRcode, each restores to a valid .bitkeys file, i.e. starting with the v=1 line, then including the key and comment.

Interesting discussion going on here! As a recent customer, let me give my 0.02฿:

I don't care if or how much profit vladimir earns with this service. First, it's a service, and like normal offline services for which I also have to pay I assume the person who offers it makes a profit. If not, why would he make this offer? And I have absolutely no problem with someone earning money with a provided service; in fact, that's what I do for a living, too.

Second, I just made a back of the envelope calculation how much it would cost me if I wouldn't use this service, but do the work for myself, by myself. Yes, if I only calculated the cost of hardware and electricity, than maybe it would be cheaper than using his service. But, I'd need a place to store these boxes, and either I'd have to pay for a decent DC, or I'd have to put these loud boxes somewhere in my home (no way!). I'd have to go around looking for the necessary equipment, do research for the best hardware, the best software, install everything, and tweak the settings. If I multiply the time needed for this with my hourly rate, vladimir's service is actually cheaper!

Of course I like to learn new stuff, but really, I've got more interesting things (for me at least) on my ToDo and ToLearn lists than building clusters and tweaking CUDA or Assembler code. So, if you don't have other projects that fulfill yourself, and find building clusters fun, than don't use this service but do it on your own! It'll definitely be a great learning experience! Maybe you could even offer an alternative service, e.g. with lower costs (use your own photovoltaics to produce the energy ;-)) or instant set-up. But if you have enough other stuff to do, use this carefree service

What about the fees "earned" by a found block? Are these collected solely by the coordinator of the mining server, or are these sent to the miners, split according to their shares for this block?
