On my landmark birthday I decided to re-read Hermann Hesse’s Demian, a book from my youth, when I was still impressionable. It’s one of Hesse’s shorter works. Now, 39 years later and a lot less impressionable, I really didn’t enjoy reading it again and I finally gave up two-thirds of the way through. I recall that The Glass Bead Game was one of my favourite Hesse novels, though much longer and quite difficult. I wonder how I would regard it now.
Whilst reading Demian I also re-read a text-book, Code (The Hidden Language of Computer Hardware and Software) by Charles Petzold. I first read this in 2000 and, having always been a technical computing person through five decades of rapid changes, I found this book an easy and fascinating study of codes generally as well as codes in computing. Highly recommended.
