Hi, friends! Finally I was able to find the time to work through a full tutorial on the PHP framework Laravel. And I have to say: What I saw there is pretty cool. First of all, there is a build tool for PHP called Composer, which takes care of dependency management, comparable to Gradle in […]

On the sweet spot of testing
Hey, friends! In his great talk “TDD – Where did it all go wrong“, Ian Cooper points out how our common way of unit testing fails the promise that the tests would enable us to refactor the system, by giving us confidence that we didn’t break anything.That common way of unit testing I’m talking about […]
Three tips on writing great unit tests
Hey, friends! I assume you already know technically how to write unit tests, and you are also applying the given-when-then pattern (a.k.a. arrange-act-assert) to make meaningful and understandable test cases. As a professional developer, you will often extend existing behavior of the software and you copy and modify existing tests. But when you have to […]
On “machine learning for dummies” (I)
Hi friends! I told you on my last reading list article that I happened to bring “Thoughful machine learning with Python” from the library, just for fun, a look outside the bubble… When I started to read that book, I realized that this was not an introduction to machine learning, but something like the “Clean […]

On “Head first PHP and MySQL”

I decided to publish this post as an article on Medium, just to try it out. Go ahead and read it!
On lists and sets
You probably don’t even need to think about what Collection type to use when: If you need to preserve the order or duplicate entries, you take a List. Otherwise if order does not matter and every element should only be contained once, you’ll use a Set.Although nearly every programmer is able to explain that when […]
On Kotlin and Java
Hi, friends! I already mentioned that Kotlin is my favorite programming language. Even more, although most of my professional experience is in Java and I liked working in that language, I can bluntly say that I would never again choose to work in Java instead of Kotlin.A lot has been said on this topic by […]
