Semaphore

The Little Book of Semaphores” by Allen B. Downey has been highly recommended on Squeak-Dev. This is a terrific source for understanding semaphores and learning how to apply them. The book includes puzzles and examples. Visit the Unisex Bathroom or help the Baboons crossing a canyon.

  1. I’ve been putting off learning about concurrency for years, and now I find it’s not nearly as painful as I suspected. This book is very well written and the little puzzles along the way are a great learning aid. Thanks for posting this.
