These problems are really recurring to the collection "for Dummies" that each time contains notices which are certainly viable, but that does not go further than that.
Also after reflection, I find paradoxical to make a book large enough for beginners for a machine like Raspeberry Pi: ok it must be a beginning, but whoever buys this kind of product is completely plug of how to use word processing or well how to launch videos. The user types a Raspeberry Pi is that of a techie who knows his basics. I do not see how someone who needs advice in this book could lead to using this product.
