Just posted another update.

I'm in the UK and use Intersango to sell my bitcoins and the money is in my bank the same day. Sending money to them should be just as quick but I havn't done that. I've no idea how long it takes with EUR and USD but if you're in the UK, Intersango is easily the best option.

The most annoying part of the process you listed is transferring funds between banks and exchanges because of the wait. I don't see what you can do to make that any less annoying. The exchange websites are pretty simple to use as is sending BTC to someone.

I don't see how that could be caused by the GUI. All the GUI does, is run namecoind as a process, passes it commands and intercepts the output. Have you reported the problem to the namecoind developers?

This is just a GUI for the daemons, so it would depend on the daemon allowing you to do it. You can transfer the whole data folder, but I suspect you're talking about individual transactions and I don't think they support that.

I'll look into it though.

Just letting you guys know there's been a few updates since I first posted.

What's the "comment-to" for?

You can already do this if I'm not misunderstanding something.

sendfrom [minconf=1] [comment] [comment-to]
sendmany {address:amount,...} [minconf=1] [comment]
sendtoaddress [comment] [comment-to]

You just need to use the daemon. I think I'll add it to my GUI tomorrow.

At the moment I'm doing some programming in Visual C# 2010 Express, I've got a few tabs open in Notepad++, I'm seeding a few torrents in uTorrent, I'm listening to some Pink Floyd in foobar2000, got my namecoin gui running and the namecoin deamon, and Firefox with a few tabs open. I'm still getting around 330 Mh/s with no slow down of my computer.

I have noticed the slowdown your talking about though. I get it now and again when I visit certain websites, github for example. I just temporarily turn on on my workers off though and when I'm finished with that website, restart the broser and turn my second worker back on. Problem sorted. I can even watch video without any problem and still get 315 Mh/s.

You just have to configure your system properly.

Professionals? If you say so.  Where do you think the knowledge and tools come from to overclock your GPUs? The real professionals are gamers.

Sometimes. I've got a monitor and a TV connected to my PC. If I'm lying in bed, I use the TV, otherwise the monitor.

I mine on my gaming PC. A 6870. I just overclock it when I want to mine, basically, whenever I'm not gaming, and reset it to stock when I want to game. It only takes a couple of seconds.

I just had an idea that I think would be excellent for increasing bitcoin popularity among merchants.

Example:

I'm selling something that I charge £100 for, but I also take bitcoin as payment and the buyer chooses to pay using bitcoin. I use an exchange's API to query the buy orders and calculate how many bitcoins I would need to immediately sell in order to earn £100. This is the cost of the product in bitcoins. The buyers sends that amount of bitcoins directly to the exchange using the sellers deposit address and the coins are automatically sold immediately. Once the coins have been sold, the exchange notifies the merchant and the merchant completes the buyer's order.

This would require the bitcoin client to allow you to enter a reference number and send it as a comment.

What an exchange could do to help with this.

• Implement a new api call that takes a currency value as its parameter and returns a bitcoin value. The bitcoin value is the number of bitcoins that would need to be immediately sold to earn the specified currency value.
• Implement functionality that allows bitcoins to be automatically sold as soon as they are deposited. In the case of confirmations being required, the coins could be "virtualy" sold until the required number of confirmations has been met. The buy orders would be temporarily removed until then and if the deposit could not be confirmed, the buy orders would be reinstated.

You can grab any future updates from here from now on.

Here's a Windows Namecoin GUI for managing your wallet and domain names. It also allows you to manage your bitcoin wallet as well. Switching between namecoin and bitcoin is as simple as clicking Tools -> Switch to, then choosing either Bitcoin or Namecoin. It's written in C# and requires the Microsoft .NET Framework 4. Let me know of any features you'd like to see implemented and of course, any bugs you come across.

If you are not interested in using it for bitcoin, just leave the bitcoind path empty.

It found the instructions on the site to be pretty straight forward. I'm pretty technical though but you shouldn't have a problem. If your using Windows, I've also made a namecoin gui which also supports bitcoins as well. I'm hoping to post it here but you can also get it from reddit or the namecoin forum.

I've recently made a namecoin gui for Windows users. I'm hoping to post it when I get out of the newbie section. You can currently get it from reddit though.

I stopped mining on Ars because they hadn't implemented merged mining. I currently mine at Eligius and Simplecoin, both of which offer SMPPS.

I read a thread about that the other day, and the coins were being generated every 6 seconds despite the diffuclty rising. It looked like a scam to me. I think I'll loook that thread back up, it was pretty amusing.
