So you know about object oriented code and wrapping functions up into classes with similar behavior. This talk will take you on a deeper dive into SOLID, a mnemonic for five rules of well-designed OO code. It also covers some common design patterns, with examples, and cover some further guidelines …
So you consider yourself an Object Oriented (OO) developer? Ruby isn’t limited to an OO style! See what functional programming can do for us, without learning any new language. These six principles of functional style apply in OO code.
By now you should have heard about coupling and cohesiveness. These concepts, and their third cousin, polymorphism, is what we as developers chase day-in and day-out. They tease us with reusability and the promise of comprehensiveness of our code. They entice us with promises of code quality and testability. They …
