ØMQ - The Guide
This book is written for professional programmers who want to learn how to make the massively distributed software that will dominate the future of computing. We assume you can read C code, because most of the examples here are in C even though ØMQ is used in many languages. We assume you care about scale, because ØMQ solves that problem above all others. We assume you need the best possible results with the least possible cost, because otherwise you won't appreciate the trade-offs that ØMQ makes. Other than that basic background, we try to present all the concepts in networking and distributed computing you will need to use ØMQ.
