Hat zufällig jemand von euch zwei Casacius' 1BTC Münzen, die ich morgen erstehen könnte? Eine wär auch ok, entwertet ginge auch.

Bis morgen dann,

..what really makes me mad about this address is not that there are already coins being sent to it, which now are unrecoverable.
This address is the address for the firstbits "1bitcoin", which would have been an awesome address in my wallet, on the phone, on my business card! :-)

2107  Economy / Marketplace / Re: [BETA] MTGox websocket API, testers wanted on: October 26, 2011, 03:29:34 PM
I am having problems with Websockets and Ruby in general, maybe someone of you is kind enough to help out?
I am beginner with Ruby and chose this as a learning-by-doing project.

Using examples from the web, I am still trying to connect to the websocket (works) and sending strings to it (handshake and channel subscription/exiting):

Code:
require 'rubygems' 'eventmachine' 'em-http-request'
 
EventMachine.run {
  verbindung = EventMachine::HttpRequest.new("http://websocket.mtgox.com").get :timeout => 0

  verbindung.errback { puts "oops" }
  verbindung.callback   {
    puts "WebSocket connected!"
                 
verbindung.send("GET /mtgox HTTP/1.1\n", 0)
  }
}

Error, my Ruby doesnt recognize "GET /mtgox HTTP/1.1\n" as a string to be "send" :

Code:
websocket.rb:19:in `send': undefined method `GET /mtgox HTTP/1.1 (NoMethodError)
' for #<EventMachine::HttpClient:0x7f9f6d22e8b8>

I tried "print", "send", "write", "<<", still didnt get it to work. I am lost, grateful for any hint!

I was going to make a nice interface for the feed as well, but I'm not going to bother until the problems are resolved:
Rounding issues
No perfect way to start out in-sync
Alleged missing data and dark pool inconsistencies

How about these and the wss://?
Its been months that Mark didnt post here now..

And, general question:
I chose this API as a starting project to learn ruby.  Maybe a bit (too) ambitious, but would at least be a useable project, if it ever gets finished..
Are there real advantages of this "new" websocket API over the old HTTP API except that I dont have to poll any more and have instant updates (instead of every 10 secs)? I would at least not have the syncing issues?

With the probably still unsolved issues I hesitate to invest much more time into this - being a novice I still am trying to actually post to the websocket.. *rolleyes*

Thanks,

Sounds good, thank you for clarifying, Francisco.

One more question: When I transfer Euro to my account, is it possible to trade that funds in US$? Similar to what MtGox does (automatically exchanging any currency to US$). The volume in other currencies than US$ is just too low..
(Yes, I know, hen-egg problem)

Thank you again,

2110  Bitcoin / Bitcoin Discussion / Re: TradeHill - Now accepting EUR deposits - EUR market is live! on: August 11, 2011, 06:52:22 AM
Indeed great news!
I consider to switch to TH now.

About the AML rules:
What limit applies? I guess a certain amount per day per account (1000$ in USA?)?
Obviously this would then not apply if a sum was splitted up to several days or to several accounts?
What is the procedure when a sum over this limit is transferred at once?

Thank you, cant wait to finally get going!

Yep, found the "notify" botton already, thanks.

By now I found a list of all subscribed threads:
https://bitcointalk.org/index.php?action=profile;sa=notification

Which isnt exactly what I was hoping for, but close enough. Still its a bit disappointing, an easily reachable list of all subscribed topics with all stats (last reply date, user etc) is common, not complicated and so useful!

Thanks for the suggestion.

Yes, found this too, that comes close. Enough to follow all threads where something is going on. I just wont be able to find those threads again, since they obviously disappear once noone replies to them. So I would have to make bookmarks.. Good enough, I guess!

Thanks,

2113  Other / Meta / how to "subscribe" to threads? on: August 06, 2011, 06:31:58 PM
Total newbie question:

Is there a list of all threads I either posted in, or manually "subscribed" to?
I know this feature from other forum systems, its a must-have for me. Search, Google, messing around didnt help. Even the manual "notify" available in threads didnt seem to do what I ask for..

Halp!

2114  Bitcoin / Project Development / Re: Bitcoin Off-The-Grid (BOTG): secure savings script v0.1.1 on: August 06, 2011, 04:32:55 PM
..actually you can achieve what I try with jackjack's pywallet:
https://github.com/jackjack-jj/pywallet

Since I would use pywallet to import the base58 keys anyway, I can use it right away with the Hex keys as well.

If someone likes to point out which part of BOTG exactly does the conversion, I would like to see and understand!

edit:
found it somewhere:
the magic lines would be:

privkey=58c00ef49f161ac94e40cde5106227e09a6dc1840cf601c877b48d9ccc7ebdbe
encodeBase58 "80$privkey$(checksum "80$privkey")" && echo
2115  Bitcoin / Development & Technical Discussion / Re: base58 offline transaction generator on: August 06, 2011, 01:12:59 PM
I think this, to have offline transactions, is one of the most important pieces missing at the moment. Much more important than encryption on keyimport/export (which can be done with external tools by now).
No serious company handling a lot of money will accept to have their wallet.dat on an online node.

Yes, please, write a working toolset for this! This really has to find its way into the official client soon!

2116  Alternate cryptocurrencies / Altcoin Discussion / Re: [800,000 DVC remaining bounty] for Devcoin preliminary testing on: August 05, 2011, 08:21:52 PM
I would really prefer to have a new pool which gives 90% of the income to OSS and 10% to the miners instead of an entire new blockchain.
Sure, noone would join this pool. But so noone would join this new blockchain?

Remember the few real dangers for the whole Bitcoin project? Yes, one was the splitting up into several forks/chains/projects/currencies. Divide and conquer.

I encurage you to drop the whole idea altogether.

2117  Bitcoin / Project Development / Re: Bitcoin Off-The-Grid (BOTG): secure savings script v0.1.1 on: August 05, 2011, 08:04:56 PM
Great work, thank you a lot! This will be very helpful for a lot of projects, I am sure!

Being a bash-script-noob and only a bit experienced with the inner parts of Bitcoin, I need a little help:
Which part of the botg script converts the HEX key into (sipa patch importable) base58?

My plan is to do this:

- Take a known plaintext string, like "Damnesia" (from another thread)

- Create the SHA256 hash from that string with "echo -n Damnesia | sha256sum", in this example its "58c00ef49f161ac94e40cde5106227e09a6dc1840cf601c877b48d9ccc7ebdbe"

- Take the relevant part of this BOTG script to convert the SHA256 Hex key to base58, should be "5JVNazqC4JucAHUeRLhcqrbGFAro2CySd2ptDaDnPe18G9tmuAs" here


I can do it in a script by using the blockexplorer's "converter", this here works by saving it as "mkprvkey.sh" for example and running it with "./mkprvkey.sh Damnesia"

Code:
STRING=$1
echo
echo String: $STRING
HEX=`echo -n $STRING | sha256sum | sed 's/.\{3\}$//'`
B58=`wget -qO- http://blockexplorer.com/q/hashtoaddress/$HEX/80`
echo PrvKey: $B58
echo

For obvious reasons there must be a better way to do this, without transferring my private key to an online service, and without having to be online to begin with..

Ultimately I want to create a wallet.dat from a handful of passphrases, as a worst-case backup in case my regular, encrypted backups of the wallet.dat get eaten by fire, lightningstorm and house searches ;-)

As I said, I am quite new to bash scripting, please bear with me!

Thank you,

Ente
2118  Other / Beginners & Help / Re: Proposal for a decentralized BitBank on: July 28, 2011, 03:15:24 PM
I dont exactly get the difference this decentralized BitVault makes..
You still need to keep a "secret", just like you need to have a conventional wallet.dat at the moment. Lose either of them, lose your balance.

What do you want to accomplish?

If, what I assumed, you want to have your Bitcoins secure without your current wallet.dat, how about this:

-get the Sipa-patched client
-get the scripts and everything to create public-private keypairs from freely chosen passphrases
-create 10 such pairs from passphrases you can remember and/or write down
-import those 10 pairs into a new wallet.dat

voila, you can recreate your wallet.dat in case you lose all backups just by remembering the 10 passphrases!

This doesnt help in case your wallet.dat gets stolen and emptied, of course..

2119  Other / Beginners & Help / Re: BOUNTY: Wikileak body scanner images and photograph of the same person @ airport on: July 28, 2011, 03:08:26 PM
Interesting task.

What exactly do you want to accomplish? There are demo-pictures around, from the manufacturers at least..
Also, there are several companies, with several machines, with different techniques (backscatter, x-ray, thz), with different visualization-schemes. All in all maybe a dozen unique looking, maybe totally different screens? Some are "nude", some are schematics or stickfigures, some "only" see to the skin, some quite a bit deeper (afair).

I dont like those at all. Dangerous and not working by concept. And too intrusive as well. So I support your cause! :-)

2120  Other / Beginners & Help / Re: Long term bitcoin mining perspective on: July 28, 2011, 02:04:41 PM
Basically the hope is that as difficulty increases so does bitcoin exchange rates. I think the markets are consolidating at current prices. We may get about a 100% increase in 3-4 months time which would halve your current earn rate. I would still be profitable...but only marginally so I won't be mining after that (plus I would be hitting summer towards that time as well).

What he says!
Most seem to forget that when difficulty rises, Bitcoins are harder (=more expensive) to mine, so the exchange rate WILL follow! Or do you really believe that right in this week, after 2 years, Bitcoin mining suddently stopped to be lucrative? Compared to today, mining was ridiculously easy some months ago. Compared to some months ago, Bitcoins are ridiculously expensive today. Realize something? :-)

In fact, it could very well be that one of the constants are that mining hardware pays off after around three months, not calculating electricity costs. This rule, if it was to be confirmed, would not be made by the protocol, but by the market itself. Self-fulfilling regulation.

It should be possible to take a) the price per hardware, b) the difficulty, c) the exchange rate beginning from 2009, and with that calculate the ROI over time. I read about those "3 months" too often by now.. I really think it will be quite steady over time..

All data is available online!
