So I was reading on Design Patterns and I really liked the way Head First explained it, so i made a similar, shorter handbook that includes practically all the patterns covered by the Gang Of Four, You can find it on this repo, the repo serves as a companion as well so u'll find some short notes on each pattern, their UMLs and live examples in java: https://github.com/dizzydroid/DesignPatternsNutshell Thought I'd share that if anyone is struggling with Design Patterns or looking for a refresher :D #programming #dev #technology
