1202  Economy / Trading Discussion / Re: How to be safe selling gold for bitcoin? on: August 05, 2014, 06:05:59 AM
Hello I have some gold eagles that I'm wanting to sell for bitcoin.

What is the safest way for all parties involved?

Local meet-up at a public place with CCTV and security personnel that actually pays attention. An airport for example. But then the buyer will probably want to have a way to test for fakes...

Also talk to the shops that sell gold for bitcoin.

If I understand you correctly something like this?

It's still in development phase though, due to hardware limitations.

1212  Bitcoin / Bitcoin Technical Support / Re: bitcoind changing password to the RPC on: August 03, 2014, 06:43:58 AM

rpc password is set in bitcoin.conf:

Code:
find / -name bitcoin.conf

Highlight the full path and file name, hit Ctrl+Shift+C

Type nano, hit Space and then Ctrl+Shift+V

This should look something like this

Quote
nano /home/user1/.bitcoin/bitcoin.conf

Enter


Might be nano is not installed, so you could use vi. nano is easier to work with for most though, so install it with
Code:
sudo apt-get install nano

Minor bug report:

In "Settings" the explanations are cut off after 4 lines of text. (look at "Expert mode" and "Aggregated View" for example)
1214  Bitcoin / Mycelium / Re: Mycelium Bitcoin Wallet on: August 03, 2014, 06:18:56 AM
How is the change managed in this wallet?

In segregated mode, change is sent back to address where the inputs came from. In aggregated mode, change is sent to the address which provided the biggest total sum of inputs to the transaction. In upcoming HD accounts, a new address will be derived from the master seed on the 'internal addresses branch' for each change.

So you can actually send the change to the same address where it came from? I had no idea about this and now it seems strange that the bitcoin-qt client was using a separate address for change which caused a bit of problems. Tell me more about the aggregated mode. I see that I can have multiple keys/addresses, but from the looks of it I can only send money from a single address, not multiple so the change address is always the same. Am I wrong? Can you send money from multiple addresses in one transaction?

An example:

Add1     1BTC

Add2     2BTC

Add3     4BTC

In aggregated mode you can send 6.5 BTC and the change will go back to Add3. It doesn't matter which one you select. The selected key is there for receiving purposes only in aggregated mode. If you select a key in the Keys tab there is a short pop-up message explaining this when you select a key.

How does one get to be a beta tester? i can volunteer if you want. Just to show my love for this app.

Beta channel

In order to receive updates quicker than others, you need to do two things:

to be eligible for testing you need to join the g+ group at

https://plus.google.com/communities/102264813364583686576

after joining, you need to explicitly enable beta versions for the software at

1216  Bitcoin / Mycelium / Re: Mycelium Bitcoin Wallet on: August 03, 2014, 06:09:09 AM
In general, it would be worthwhile to have the ability to work in text.

[...]

There's manual entry for the address when sending already, so maybe that could be added to private key import. Then you just have to flick between the app windows. Talk about _work_ Smiley

This app can "scan" QR codes from image files: https://play.google.com/store/apps/details?id=appinventor.ai_progetto2003.SCAN&hl=en

You then still have to "share" the result with Mycelium, which was talked about before (for addresses anyway), but there are some URI issues, IIRC. It'll be even worse with private keys as I think there is no URI for them at all.

Could Mycelium be set to MIME type text/plain (AndroidManifest.xml) ? Of course it would then show up in the chooser every time you want to "share" plain text within apps.

I'm also not sure if the "share" function makes use of the clipboard.



1217  Bitcoin / Mycelium / Re: Mycelium Bitcoin Wallet on: August 02, 2014, 04:53:05 PM
Import of private key from clipboard is disabled. You can only import through a QR code, but as far as I know, there is no safe way to generate a QR private key without using some web interface.

It's not disabled (v1.2.12), but as long as there is no private key in the clipboard, the button will be greyed out.

There are offline QR generators, such as QtQR, I'm sure there are some for Windows too.

"All command-line options (except for -datadir and -conf) may be specified in a configuration file." Source:https://en.bitcoin.it/wiki/Running_Bitcoin#Bitcoin.conf_Configuration_File

You can't use the "datadir=" command in the bitcoin.conf file.

Nice catch.  Smiley
1219  Bitcoin / Bitcoin Technical Support / Re: Relocating the blockchain data on: August 02, 2014, 11:19:09 AM
That's odd, what does your bitcoin.conf look like?

I've searched but cannot find a bitcoin.conf associated with that bitcoin-qt.exe from what I can tell. Perhaps I'm missing something? [..]

You have to create it yourself. You then can put datadir= in there.

There is some more info in there. I have used it successfully before.
