There are many tutorials on the web, on various subjects. The approach I tend to use, here, might compliment other tutorials, elsewhere, and provide just a different take on the same subject. A few are provided just for convenience, so that other tutorials, here, can refer to them for basic intro stuff - instead of having to repeatedly explain in each tutorial. [For more general treatments of programs, design issues, projects, and so on, look over in the ARTICLES section.]
