This is a fantastic book!

I have a virtual calculator called the DIY Calculator that accompanies my own book "How Computers Do Math" The Definitive Guide to How Computers Do Math : Featuring the Virtual DIY Calculator.

I recently added a "Conundrums, Puzzles, and Posers" section to the "Programs and Subroutines" page on my DIY Calculator website ([...]) and I've started to build a collection of simple puzzles for people to play with.

One of the first problems I posed was to count the number of ones in the 8-bit accumulator and to present the result as a binary value. I thought I had discovered the best-possible solution, until someone pointed me in the direction of the "Hacker's Delight". (In this context, "Hacker" refers to a hero who is manipulating code; not a nefarious rapscallion who breaks into other people's computer systems.)

I immediately ordered a copy from Amazon, and took delivery just yesterday as I pen these words. This book is fantastic - I kid you not - on the first page of Chapter 2, for example, I discovered at least five or six capriciously clever tricks that blew my solutions out of the water!

I highly recommend this book.
