Have you ever wanted to completely isolate your private keys from networks and removable media?  Armory nearly accomplishes this, but still requires removable media to move the transaction content back and forth.  I've created an Android app called Armory Companion that allows you to broadcast signed transactions on the bitcoin network after signing with your offline Armory instance (or any other bitcoin instance for that matter) using QR code scanning.  There are some tiny python scripts that run on the offline computer to facilitate QR code scanning with the webcam and generation of the final signed transaction QR code.

See this video for a demonstration of how it works: http://www.youtube.com/watch?v=ZlSC3mLjNSg

This post shows that this is something other people want, so I figured I'd share it:

Feel free to fork and modify as you desire.  The app will be on Google Play soon.

Get an electrician to put in an L6-30R, which will do 220V 30A (6KW or so).  It only costs a few hundred $.

You have no idea how to use that calculator.

Armory's not windows only - works in Linux and I even recently tried an OSX version, but it's not "there" yet.  I does fetch the blockchain using bitcoind, so if you've already done that, you're good.  I really like multibit - even in the Linux machine I use for bitcoin it works great.

Truecrypt will help if your computer gets stolen, but if you get hacked while it's running (much more likely) then they'll be able to keylog you and get your bitcoins.

Consider getting VMWare Fusion and making a rather hardcore Linux VM to keep your coins in.  It provides yet one more layer hackers would have to get into to get your money.

I'd still rather get what I ordered late than half my money back.  And they gave refunds until June and very publicly stated that they were stopping refunds to enter production.

I really hope they take it seriously and implement demurrage in the USD.  That would send people to BTC in DROVES.

I love how short-sighted this argument is.  Here I'll make it really simple:

• Buy something with BTC
• Open coinbase and buy the same amount of coins back

That should answer your question.

I didn't buy Terrahash, but here's the outcome if I had:
Hashrate delivered

Company	Hashrate delivered and running
BFL	540GH/s
Terrahash	0GH/s

So, it comes down to what "reliable" means.  LOTS of BFL customers are hashing with their hardware, and ZERO Terrahash customers are hashing with their hardware.  Sure, BFL was super-late, possibly lied through the process, produced a few duds (I have a slow one myself), produced and shipped units REALLY slowly, but in the end, they did deliver, and I'd say that's more reliable in the end than a company that goes under and can't even fully refund everyone.  Of course, you're right that there's just more BFL customers, so maybe proportionally Terrahash customers are more upset about Terrahash than BFL.  All of my BFL hardware has more than ROI'ed in USD (yeah yeah I know it will never ROI in BTC opportunity cost).

Of course, you could say Terrahash's statements were more reliable than BFLs - I agree there.  It's just that one of those statements was "we're done and you don't get your money back."  That is a pretty reliable statement.

5.9 billion looks like a decent estimate to me.  I think it might even be a little high.

Here's the response I got when I asked some questions about their hardware:
They didn't protect their data well enough?  THEY SOLD THE CHIPS TO MAKE THE CLONES!  Apparently they don't even understand what happened here.

What is the funding for?  He can get a public defender.  The evidence against him is massive anyway, so what's money going to help with?

How is terrahash not winning this poll?  BFL shipped, Terrahash can't even refund half of customer's money.  We're talking about reliability here, not lateness.

I only got 517GH/s from the 540GH/s I ordered from BFL.

Looks a little scammy to me - especially the projected performance - 0.3J/GH @ 28nm?  That sounds a bit low.

Another thing you can try is moving aside the wallet.dat file (back this up somewhere while you're at it), then moving the entire Bitcoin directory aside, and starting bitcoin again to force it to recreate the directory.  Then, close bitcoin, and move a copy of the wallet.dat back over the newly created one.  The only important file is the wallet.dat, so as long as you keep a good copy of that around, you can get the coins back.

2-3 Bil is my estimate, based upon estimated ship dates of various manufacturers.

Just quoting this for posterity so I can laugh really hard at it later.

Any CP in the blockchain yet?  There probably is, even if it's encrypted.  You'd never know, and you'd be distributing it to the scum of the earth.
