Concretions are more likely to change than abstractions, and those changes will ripple through our codebase affecting all the classes that depend on them. We also lear...

When I started writing my first lines of code, I felt super excited that I could make a machine do things. Granted, they were very simple things, but I felt I could achieve anything with this cool new skill. After a while, I started to notice t...

Dependency injection is one of those techniques that carry around a bad reputation for being overly complicated and hard to understand. In reality, DI(you guessed it, dependency injection) doesn’t need any complex framework or fancy library to be useful, you can start using it very easily. Let’s start with an example class Robot, that uses an a...

It’s also unlike lots of other crafts in an important sense: the end product, instead of being a tangible thing, is materialized thought running inside a chip. This notion of programming as a translation of your i...
