What our readers say about the newsletter?

Loved that pigeon article! Thanks!
I really liked the "Modern Microprocessors - A 90-Minute Guide!" and couldn't stop reading! This article not only made my day, but also made the newsletter a very important weekly task that I'll be looking for.
I learn something from each edition of the Programming Digest.

Effective Software Testing – A Developer’s Guide

The book also covers many other common topics relevant for developers writing automatic tests, such as: test-driven development, mocking, designing for testability, and property-based testing. The author does a good job describing these. I especially like the code examples – they are larger than the most basic cases, but still small enough to easily keep in your head.
