I was implementing a searching algorithm and I had to search for two things. In this article I describe how I implemented combining two Java optionals.

I’m doing a side project using golang, and I have a use case where I’d use an abstract class in Java. Unfortunately, in golang the concept of classes does not exist. In this article I describe how can I implement the behaviour I want without abstract class.

My dog has a little bit of separation anxiety so when we leave him alone, he barks some times. We are training him to be home-alone and we want to know if he barks or not when we are not home. Let's implement a bark detector!

We performed a migration to Java 11 and a bug fix about negative symbol for negative numbers in Java ruined our implementation. This article describes the situation and the lessons learned.
