C - Tips'n Tricks - Retrieve temperature of hardware devices

The file from where we can retrieve temperature depends on the operating system.
For this tutorial I used Ubuntu 12.

C - Tips'n Tricks - Creating a clock with six numbers after the decimal point

Everyone knows that a clock is essential in a video game.

And the more the clock is precise, the more we can do things.

That's what we are going to see in this clock tutorial by creating a clock with six numbers after the decimal point.

C++ - OpenGL - Using glRotatef() to rotate around the X, Y and Z axis

In this OpenGL 2.1 tutorial we are going to use the glRotatef() method.

This method is designed to rotate around the 3 axis: X, Y and Z.
In the example below I will use a black background and draw 3 triangles.

UNIX & GNU/Linux - gcc - Option -L for adding libraries during linking

We can add libraries during the linking step.
This tutorial is the same for g++ of course.

UNIX & GNU/Linux - gcc - Option -I for adding includes to the compilation

Python 3 - Data types - Using a tuple

A tuple is like a list but without possibility to modify it.

We can see a tuple like something declared once to be sure data inside won't be modified in the future.

Python 3 - Data types - Using a list

The list data type is like a container.

So we can manage it like an array in other programming languages.

In this tutorial of the Python 3 data type list, we are going to play with all methods of the list.
