Yeah, much better, good job!

Thanks for the latest commits. There's still some "ugly flashing" at startup though (noticeable at least on my slow netbook)

I just fixed that if you see my last commit. Does it still show for you?

bitcats: nice, tyty Smiley that made me really happy.

Yes, my previous post was with the latest commit.
There's less flashing than before the commit, but there's still something unfortunately.
Anyway, I think it can only be noticed on slower computers, so probably not too urgent
to fix. I might even try to take a shot at it later.

Sent you some bacon 1LDjY9  Smiley

Bitcats is becoming one of Electrum's biggest sponsors! Smiley

I am trying to use it for the first time. Where is the wallet file stored in portable mode? I don't see it.


Portable mode:
 The wallet (electrum.dat) is stored in the same directory as the executable file.

Which server are you connecting to? Can you try ecdsa.org?
925  Bitcoin / Electrum / Re: Electrum servers not working on: July 05, 2012, 02:52:14 PM
Electrum not connecting to its servers. Anyone else have this issue?

I am able to connect just fine.
You might have a problem with the wallet file (electrum.dat).
Do you remember doing something particular in Electrum when the problem started?

If you're in a hurry to fix the issue, try this and let me know if that helps:
just rename the electrum.dat file to electrum.aaa and restore the wallet from
your seed or mnemonic code.

Do all clients use the same wallet file? Can I just open and use the same wallet in different clients?

Or does each client have its own wallet? Which means you get locked into a client more or less?


Unfortunately, each client has its own wallet format.

If you want to try a new client, you basically have 3 options:

1. You can export the private keys from your existing wallet to import them in the new one:

   Each client has support for private key export and import. However, in some clients, this needs
   to be done through command-line parameters.

2. You go for the gradual transition: While you test drive the new client, you just keep using
   your current one as well, and maintain 2 separate wallets

3. You decide to send the coins in your existing wallet to one of your new addresses:

   This is probably the best solution once you have decided that you do want to switch clients,
   but you will need to update your contacts, web pages, forum signature,  etc with
   your new address(es)

And of course, always back up your wallets.

The problem with moving the balance:

- Click the label
- Type stuff inside the amount field

See what happens. You lose that functionality with it in the titlebar.

Actually, I didn't mean to move the balance to the title bar,
but to only show the BTC value (not the EUR) in the title bar, because
it is not wide enough to contain both the BTC value and another currency.

Sorry if I wasn't clear. Let me know if my explanation is still confusing.
928  Bitcoin / Development & Technical Discussion / Re: Electrum lite GUI on: July 05, 2012, 09:27:57 AM
Interesting. I guess 2. is a problem then.

A tooltip might not be immediately obvious. I changed it to "Copy My Address" but that seems a bit wordy. Try it out and tell me what you think.

I'm thinking maybe a small popup should appear over the button with the address and some text saying "Your bitcoin address for receiving funds has been copied to your clipboard!". I'm wondering if a minimal/small popup that closes by itself might still be sacrificing usability and quickness by increasing the number of clicks. But certainly now there isn't enough "feedback" as to the action that's just happened.

I'm glad the SSL thing isn't a bother. Saves me a tiny bit of effort Smiley

To me the meaning of that button does look clearer / more intuitive now.  Thanks!
(Of course, that's just my opinion)

Also, how about only showing the BTC balance in the title bar?
The EUR value doesn't show anyway due to the small width of the window (see screenshot)

That latest version crashes for me (win XP, 32-bit)
right after displaying difficulty. V0.17 still working just fine.

Thanks for the tutorial.
I'd prefer to use electrum with TOR.

Agree, that would be great...
931  Bitcoin / Bitcoin Discussion / Re: Flatfly's Ultimate Guide to Anonymous Transactions on: July 04, 2012, 11:14:12 AM
Thank you for your guide. It looks good!
However, one big obstacle was not covered yet: How to get Bitcoin to begin with? I definitely do not trust MtGox on this one.
One could mine on p2pool, where no registration is needed (nor possible) and you receive Bitcoin right from the coinbase of the mined block.
Or trade Bitcoin offline, swap cash with a usb stick.
Or, if you trust the concept and operator, use a tumbler to wash your initial coins. TORwallet comes to mind, among a few others.

Thanks for compiling all this, this is important knowledge!

Ente

Thanks a lot for your feedback and suggestions!
I agree that a section on getting anonymous BTC to start with would be good to add. I will look into it some more.
932  Bitcoin / Development & Technical Discussion / Re: Electrum lite GUI on: July 04, 2012, 09:56:07 AM
Nice job, genjix!

Here's some quick feedback from me (as a Win XP user):

- I like the size of this GUI. Very nice for casual/mainstream users.

I do have a couple of bug reports & suggestions:

 1. Not sure if this is a Windows-only problem, but when launching Electrum for the 1st time after a cold boot, the balance in the lite GUI stays stuck on 0
     (not on subsequent runs, though.)

 2. The Copy Address button seems to copy a random address if clicked right after launching the app
     Do we really need that button anyway? IMHO, it's taking valuable space and doesn't seem that useful to me.

 3. Is it critical to use HTTPS to get the exchange rate? The reason I'm asking is that the resulting Windows
    stand-alone executable would get significantly bigger if I have to include ssl.py and its dependencies.
    It would be around 7+ MB rather than 5.9MB without it. This kind of thing could matter when targeting
    the Windows audience.
 
 4. Hopefully the theme/icons/colors are not final as they could be a lot more polished IMHO.

1. yeah I noticed this. Will have to fix it. (edit: fixed this)
2. But then how will you get your receiving address?
3. I see. Let me investigate this. Thanks for letting me know.
4. Software always looks pretty crude initially. We'll have to fine-tune it as we go along. Perfection is a journey. But I definitely want to have it be eye-candy.

1. Thanks!

2. OK, it wasn't immediately clear to me that the "Copy Address" button was copying
one of the user's *receive addresses* to the clipboard. (Should've read your OP more
carefully!) Perhaps I was misled because the only other reference to the word "address" in the GUI is very near that button, in the input field for *destination* address. Perhaps the button should be renamed to something clearer (such as "Copy My Address" but that might be too long), or have a little  explanation in a tooltip, or provide some feedback after it has been clicked?

3. I've tested an alternate (7z-based) compression method in the meantime, which will
only add 150K or so to the download size, so I guess this is not really an issue anymore
(Although I wish the PyQt libraries were not as big, as they currently account for about 85% of the Electrum executable size on Windows, but that's another story...)

4. OK, great!

My dream: finding a Bitcoin-related job! I would probably say YES right away!
I have a job to offer: Creating a small but fine website for 80 BTC.

Wow that was fast, I just updated my signature 5 minutes ago Smiley
I'm not the greatest website expert, but PM me with more details on your requirements
to see what's possible.

i'm not sure how happy tor users will be if people start downloading the blockchain through tor

Indeed. I hope Bitcoin-Qt will be smart enough not to download the blockchain itself through Tor.

Here's what's been announced so far for 0.7.0, re Tor support:

We're very close to adding much improved Tor support to Bitcoin, so it will most likely be in 0.7.0.

Among other things:
  • Support for running as and connecting to Bitcoin hidden services
  • Peer exchange of Bitcoin hidden services
  • Non-leaking DNS seeding via proxy

Off topic:
Could you tell me what is the easiest way to make an anonymous transaction using electrum?

If you're still interested in that, check out my new guide to anonymous transactions Smiley
937  Bitcoin / Bitcoin Discussion / Re: Flatfly's Ultimate Guide to Anonymous Transactions on: July 03, 2012, 09:45:25 AM
Would accessing Blockchain.info/wallet via Tor pretty much give you everything you need?  

 Tor + CoinControl?

 - http://Blockchain.info/wallet

The custom send function of BlockChain.info does look pretty nice (I wasn't aware
of its CoinControl-like capability) and it's great that you can easily access it via Tor!

However, there are also 2 cons I can identify with it:

- change address:
 while it allows some control over the change address, it doesn't support
 specifying an arbitrary change address, as far as I can see.

- I guess you do need to trust the Blockchain.info server not to spy / keep
  usage data on you

However, I will test it some more as I do think it is very promising.

In the meantime, I have updated and rewritten large portions of my guide, and the
approach and ideas are presented in a more consistent way now.

Why are you intelligent guys wasting so much lifetime, intelligence and bitcoins playing this absurd SatoshiScheiss?

I played it 2-3 times and didnt find out any sense! It's not even fun  Huh

I guess we all have some weaknesses...
939  Bitcoin / Bitcoin Discussion / Flatfly's Ultimate Guide to Anonymous Transactions on: July 02, 2012, 08:26:36 PM
I often get asked how a Bitcoin transaction can be made anonymously.

As the answer is not that simple, and I couldn't find a hands-on document on this subject,
I've tried to compile the research I've done so far in an easy-to-read guide, which can be found there.

It's still very much a work in progress, so feel free to analyze, comment or point out any mistakes, omissions, or inaccuracies. I know it can still be improved in many ways, but I hope it can answer some of the most common concerns about Bitcoin and anonymous transactions already.
940  Bitcoin / Electrum / Re: [ANNOUNCE] Electrum - a new thin client on: July 02, 2012, 06:49:21 PM
Aren't change addresses supposed to be used only once, by default?

Some of my change addresses have been re-used many times (see screenshot) - not sure why.


OK, it seems this is related to the way SatoshiDice works, so not an Electrum issue I believe.
