I want to teach my son to be a strong PC user. I could try to strike out on my own for this, but I was wondering if there is a good online (or book based) course for this.
Like most kids, he's proficient with Google, YouTube, and Minecraft, but he's very curious, and I would like to teach him more. Even some basic excercises, like working with the file system would be good for him (i would need some help to not make it boring).
