Nice introduction text with detailed description to set-up a R.Pi and interesting examples (AES, calculating Euler's number, Rubik's cube etc.). Shame it uses

Nice introduction text with detailed description to set-up a R.Pi and interesting examples (AES, calculating Euler's number, Rubik's cube etc.). Shame it uses an utterly obsolete language of which most interesting feature (byte code interpreter making porting the compiler to new architectures comparatively easy) was important in the seventies with its plethora of architectures (many short-lives), but hardly today.
