isazi's home

A Saturday night in Amsterdam and we are on the streets.

A bunch of people are walking around Leidseplein, trying to reach the Melkweg, not for going there, just to meet another bunch of folks in front of it. They’re almost all Italians but there is a Swiss guy too, just like on the jokes. Between them our hero (you know and we know is not, but for God’s sake, let him be happy sometimes) in the middle of a tremendous testosterone crisis.
The folks are about to decide where to go, when our guy and some other peoples decided to have their backs laying on the side of a parked car. The owner of the car was a policeman.

p: You were sitting on my car ?
i: Yes sorry.
p: I’m going to check. If there are any damages I’ll sue you and then I’ll shoot you.

Lucky fellow.

A Saturday night in Amsterdam, a Belgian pub near Leidseplein.

On the scene different characters, between them isazi and a girl. We don’t know if they know each other or not, neither they do, we don’t know what they are saying, or if they’re talking. What we know is only that at some point a conversation takes place. We can remember the content of the conversation but not exactly all the words. More or less the content of the conversation is the following one.

g: Are you Italian ?
i: Yes. How do you know ?
g: Oh, your English is so bad that you can be only Italian or Spanish.

Fail.

It’s simple, I’m reading some old C code right now (but it’s a general thought really) and it lacks comments so I’m trying to understand what it does for using it proficiently, I know that I’m not a “comment guy” cause I only now and then put comments in my source code, but managing a medium C++ project in the last few months (my bachelor thesis) I’ve finally understood what to comment and what not.

First of all I don’t like commenting every line of code, it’s stupid and it’s wrong, good code must be readable also without comments, comments are for helping readers to understand the “whole thing“, so they must refer to widen pieces of code, pieces that you can understand also without the comments but that with them become more easily to be understood by you.
So I’ve started to comment the critical point of my code, the decisions taken and the rationale beside them and I’ve found, finally, what I absolutely need to comment: data structures.

The rationale it’s simple, if algorithms have a behavior that you can follow to understand them, data structures haven’t, you can’t understand them if they want, or better, you can but you have to spent lot of time trying to find every use of them and it’s not cool, absolutely isn’t

So, I started to comment my data structures, their fields, how they must be used and the meaning of them, why don’t you ?

(This is all because the code I’m reading right now has no comments and some strange graph data structures with fields not understandable if you are not the author, and I’m not)

At the beginning my intention was to write a post with the tale of my travel, but at the very end, my travel was mine and i cannot explain with words how it was, so, the only thing that i can share are some pictures.

I just woke up this morning and turned on my tv (or better my brother’s tv cause i’m at my mother’s house waiting for taking a flight to London) only to find Mariah Carey with “Touch my body” video.
