I have special warm feelings for Beej's guide.

I remember particularly enjoying the warm and jovial tone in his guide.

I first read through it some 20 years ago while being a student in an easter-european university, where the tone and style of professors was very "dictatorial", dry, and overly-technical.

Beej's style of exposure was a breath of fresh air, and brought a major realisation for the then young-me, that you can teach complex topics in a friendly manner.
