Anybody, who is trying to learn a programming language, or who generally has something to do with some piece of software, has a first step to make.
It's lesson n.1, the IT equivalent of "The Cat is on the Table" in some english course, it's the first thing you learn.
And it's the first time your software answers to you, directly and politely.
It tastes of nights spent alone, in a dark room, just you and the green light of your old monitor.
You type some code, you hit "Enter", you let your computer compute.
You hold the breath for a timeless second and then...
Pops out on your screen.
So... Hallo World, nice to meet you :-)
