Less nerdy (hopefully)

Okay, as promised, here is something less nerdy, I hope!
Did you know about Bitcoins yet?
Assuming that you don't, this post will explain them to you. I stumbled upon Bitcoins a few days ago.
Bitcoins are a anonymous and decentralized Cryptocurrency.
What does this mean?
Well, let's see this Video, it will clear a lot up.

 Bitcoin FAQ

So, you may not understand it yet. Its a currency you can use for anonymous, free and fast digital payments. It's not the only clue that there aren't necessarily any fees you have to pay for transactions. Moreover, you are pretty anonymous as long as you use enough different account adresses (which isn't quite a problem). The transactions are probably really fast even in peak times.
The in my opinion best thing is that it's decentralized and not controlled by any government. They can't freeze your account, like paypal does all the time (wikileaks for example). In fact, the amount of bitcoins that is there is clearly predictable and thus the inflation rate is only influenced by speculation: the inflation will fade until approximately the year 2033, because the amount of  bitcoins is limited to 21 millions.
What Bitcoin does need yet is a further offer of goods to buy via bitcoins. The only thing limiting bitcoins is the stuff you can buy with it.
So, if you like the idea, support it via selling stuff for bitcoins! This will rise the demand and spread the idea!
I really love the idea and appreciate the thought that we create our own currency, without limitations of governments and the biased print-money-policy of them.
Use bitcoins!
They will get very expensive soon, so get involved now as long as the deflation hasn't stepped up!

PS: I know there will be a lot of objections in the comments. They will mainly be to the point that you like an authority like paypal to be safer for your transactions. This is discussed on the bitcoin wiki and in the forum.

Just a little calculation

Well, I wanted to show you guys a little calculation on a rather big question.
What do you think how long there will be humans on this planet left? How long will man survive?
The big deal about the calculation is that there is no need of any knowledge of the actual situation of mankind and its planet. It's just some piece of math...
Here it goes: Imagine all humans that ever lived and is going to live, set up in a row by chronological order. Just think as if you knew how long this  row was (You don't, since you don't know how many humans will live in the future). You are somewhere in this row. Now, if you don't know where you are, there is a 50% chance that you are in the first half of the row (of course, since the half of the row is 50% of its length and you don't have any information that would favor some position for yourself). For you being in the second half, there is a 50% chance, too. You can extend this: There is a 5% chance that you are in the first 1/20th of the row.
I read that there lived like 100 billons of people on the earth yet.
Now, with regards to the 50%, we can say, there is a 50% chance for humankind to survive the birth of the next 100 billon people. In fact, there is a 50% chance that humankind is NOT going to make it for another 100 billon humans.
If you think about how fast population is growing, you can either think
a) the humankind will be wiped out in the next few hundred years
b) in a few hundred years there will be only few people and not anymore billons of them living...

This calculation is not really useful and somehow inaccurate. However, it is fun to take a look at the question from this point of view, because you don't need to care about actual problems we are facing.

A less nerdy post later this day or tomorrow is incoming, hang on and don't care if you don't get what I'm saying ;)
