The main novelty here is that the author just made the entire book available to the public for free.

I have previously read the printed version, so maybe now is a time for a very brief review. The book is technically fascinating and a worthwhile read, but it is also highly opinionated even by Lisp standards. Then again, it is refreshing in this time and age to see this deeply human and creative side of programming. I wholeheartedly recommend others to read it - and to carefully choose which of the advice to follow and which not :)

Thank you so much, Doug Hoyte, for making this book available to all of us!

so the date in the title is wrong
