Software development is not a Jenga game
About the Book
Does developing software feel like you are playing a game of Jenga? Is making a change to your code very complicated? Are you afraid that making this change in your code will break something unexpected elsewhere in the code? If so then that is a clear sign of bad code, bad code will slow you down, not only months from now, but even days from now.
This little book is again content from my blog; infect it is a single blog post from 2011 about a presentation I did in 2009. I like how I can easily send this to team members for them to get a really quick and basic introduciton into the SOLID principles.
