1995? People born after the nineties can already type? Gosh, how time flies..

1995? damn kids, im old.

Hello,
I am currently working as a freelancer and project manager on other projects and making some money but I have my own bitcoin casino and the skills to finish it, I am looking for people who are ready to collaborate or invest in my project as I believe it has great potential, PM me your Skype so we can discuss this more in depth.
Regards, Max.

Good to hear that your bitcoins survived a mainboard replacement. I haven't heard about the Send button being permanently disabled before. Try and restart BitcoinSpinner (it is not enough to exit the application). You can stop apps somewhere in system settings, or alternatively restart the phone. Let me know whether that helps.

If you have access to the mainboard and the right skills/equipment I am pretty sure that you can get to the keys. However, encrypting the keys with the 6 digit PIN doesn't really help, as brute forcing it is trivial. Having the user enter a very long passphrase on a phone is not feasible (you need about 128 bits of entropy), and people are notoriously bad at choosing "safe" passwords.
If you use BitcoinSpinner to store more coins than you are comfortable loosing from a physical attack I suggest that you have two different backup QR-codes. Switching between them is as easy as scanning a QR-code. Once you scan a different backup the old keys are overwritten.
This is what I do myself, and it works really well.

Ehm... Suppose there is a connection problem and you DIDN'T get a signed receipt.

Now what, can you prove that you HAVEN'T got it? You don't even know whether server registered your trade or not.

Do you know a story about Byzantine Generals? Look it up.

BTW trade via colored coins will be Byzantine fault tolerant in some way (due to use of Bitcoin protocol which is Byzantine fault tolerant), while simplistic HTTP-based trade won't be, ever. (Not that it matters that much, but it's nice.)

This MPOE-PR has gone too far. Claiming that their options exchange is the largest bitcoin business, false accusations to ICBIT to proof that MPOEX is the biggest exchange and ICBIT is scam, now attacking everyone else.

Coooool.  Too bad I can't read it though

Incidentally, what happens if the listing isn't fully funded?

The k factor comes from the specified nature of the business (ie, BTC business). In order to be able to offer BTC business you must at a minimum be able to correctly and safely handle payments. This is a cost, in an actuarial view of the world (in the sense it is a risk you undertake, and all risks can be viewed as costs).

A traditional business doesn't one day wake up to discover that Linode was hacked and so now they have to make good on about twenty thousand dollars they thought they had safely but, as it turns out, are gone (like slush was, back in the Linode "hack" or whatever it was).

Thus, by simply starting a BTC business you are already undertaking some risks, and so are sinking in some costs. This k starts out high (but not really that high, it's likely under 100k in all cases - which makes it negligible in comparison to regulatory and compliance costs in most real-world situations) and tends to zero over time. In the case of most established businesses it may be considered no longer a significant stand-alone factor (mostly on the theory that a business past the break-even point is breaking even on all its costs, not just some selection).

Okay, it's not a crime. It's just the first step down the road which brings pretty much 9x% to crime within six months to a year. So, here are some simple easy steps for your convenience.

0. Starting a bitcoin business is a liability. The first thing you need to understand, and you need to understand it well. At sixteen hundred hours while you were sitting around your living room scratching your ear you were worth X. Your life, your ideas, your business, the shit around your house that you own, all that which makes up your life, added together, worth X. At sixteen fifteen, eight minutes after you had started your Bitcoin business you were worth X-k, where k is always positive and SIGNIFICANT. Starting a Bitcoin business is a liability, it makes you worth less. In fact, all the rest of your life in Bitcoinland will be attempts, more or less successful, to limit and reduce that liability. This is the outlook you must have not in order to be successful, but in order to have a shot at it. This is the outlook you must have in order to not guarantee failure.

How did you get that?!

Sure, sorry I didn't mean to offend. Let me explain my comment, the fundamental principles of economics are derived from logic, and that logic is best expressed in the Austrian principles of economics. The principals generally described as Keynesian are more of a social science a type of dogma.

I inadvertently compared dogma and logic and over generalized, I am sorry if I upset you.   

While I am a designer (a commercial artist), every action I take, is affected by macroeconomics, and without prejudges I can totally understand other fields of economics unrelated to macro economics being influenced by macroeconomic dogmas. 

I hope I don't seem fundamentalist but given the luxury of history, general knowledge, deductive reasoning, I can't reconcile genetics and economics without the use of dogmas. 

If someone finds someway to reduce the work by for example 20 bits it would be a million times faster.
That trick could work for all current technologies, cpu/gpa/fpga/asic.
But keep in mind, the trick would be something many cryptographers haven't found yet. So personally I would bet on quantum computers.
