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.

Except parent said

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!

What does?

Turn it off, put it back in the box and return it to the retailer - tell them you'd like your money back because you're too stupid to own a computer.

Lotus Notes.

I win!

Or Debian with the mate repositories in your sources.list, as per http://wiki.mate-desktop.org/download

What is this "European" system of which you speak?

It makes as much sense to try and lump all European countries together as it does to try and lump all the States together, for the purposes of making comparison about cultures or "systems".

You may live in the "United" States, but from an outsiders perspective there certainly seem to be many differences from one area of the country to another.

The trouble is that skype does "just work". My son lives abroad, so we use skype to talk. I'd much rather use a "free" solution (using openly defined protocols and open source software if at all possible).
I'm sure it's possible, but he also uses skype to chat with his friends and it wouldn't be easy to get all of them to use a different solution.
So, he uses multiple clients, or we all just use skype - unless we can find someting worth the hassle of converting to, which would have to work on Linux, Android & Windows.

, but not without any actual output.

what does that even mean?

No, it's not about stuff, it's about respect.

Do you honestly believe these botnets are made up of thousands of otherwise diligent users who fell prey to a zero-day attack?
The millions of those who can't be bothered to update their systems have been bloody lucky not to get caught up in it then haven't they?

And just because somebody might get caught out by a zero day doesn't automatically absolve everybody from taking some responsibility for the security of their systems.

"unknowingly" being the operative word here.
How many of these infections are caused by the user not having up-to-date AV software and blindly clicking on links in random e-mails?
You have to take some responsibility.

Ok, yes, if the owner has left the keys in the ignition, the doors unlocked, and walked away leaving a big sign on the car saying "please steal me".
