And even if you had been correct, it was an unnecessarily harsh comment, but do please feel free to hide behind the mantle of the Anonymous Coward.

Just because you're paranoid, doesn't mean they're not out to get you.

Or, you could use PGP and have encrypted e-mail today.

On that occasion I didn't complain to the manager, although I have complained on other instances - makes me sound like a moaner, but I've only felt the need to complain about something once every couple of years or so. I've also called on managers when I've received what I considered to be particularly good service - probably slightly more often than I've had to complain actually.

A manager at a dealership was rude to my wife. It might not seem like a big deal, but if you're in the customer service business it pays to be polite. This one's not a biggie, I'm unlikely to be in the market for a Toyota anyway.

No, it's easy, you make a decision based on how you personally feel about an issue and stick with it.
An assistant in a store was rude to me once, I decided not to shop there again. I've never been in the place since. She may, or may not, still be working there - I've made a decision and I'm sticking with it.

Same with Sony, I decided that one arm of the conglomerate commited an act heinous enough (to me), that I wouldn't buy Sony products - I voted with my feet.
In reality it's practically impossible to avoid Sony products since they have their corporate fingers in so many pies. But if I see a product has a Sony logo on it, I won't buy it.
Some of Sony's products are excellent, but I've decided that I won't give them my money. Some would say that I'm cutting off my nose to spite my face - but that really is the essence of voting with your feet this way.
I'll explain why I don't buy Sony if anybody's ever interested in listening, some understand my position some don't, or don't consider that it's an important enough issue (to them) - that's fine by me.
Of course, as it's purely a personal decision, I can reconsider my stance at any time - and even change my mind. So, based on my experiences, I don't buy Sony or Toyota, and I don't shop at B&Q. Your experiences will differ.

It's not, see https://en.wikipedia.org/wiki/Utf-8.
Characters encode into one to four bytes - the beauty of UTF-8 being that a 'standard' US-ASCII text document is also correctly UTF-8 encoded.

which seems to be to be referring to OTPs in general, not this specific implementation.

How do you make sure that the key is not compromised?

Debian Wheezy is the Linux kernel based O/S we all know and love - Debian 7.0.
The Debian devs took a huge number of the packages available and re-built them to work in the Hurd environment, which uses a different kernel.

There are probably no inherent benefits to using Hurd over Linux - and there are certainly many reasons for picking Linux over Hurd, support being just one of them.
If you have a spare VM though then it may be worth installing Hurd just as a learning process.

That's sharp!
