There are lots of articles and even books about the art of writing clean code. But when exactly is code actually to be considered clean? Today I’d like to give you a brief overview of how you can assess and improve your code quality. I should perhaps note that writing good code, and therefore this article, is independent of the programming language used and is rather methodical in nature. However, for more detailed information, I recommend that you really get a book on the subject. The standard advice on this is certainly “Clean Code” by Robert C. Martin. ...

I have been asked all too often which programming language to learn first. And I’ve heard almost the same number of different opinions. Java or C++? Python or C#? Or maybe C? High-level programming languages like Java offer the big advantage that the entry hurdle is very low. You can quickly put together a functional application that does what it’s supposed to do. The extensive ecosystem allows you to make rapid progress and concentrate on the functionality of your software. But that’s exactly the point that advocates of programming languages like C or C++ criticize. These are generally referred to as " more difficult “, which is due to the lack of abstraction of different system concepts. The most common example is probably memory management. While in C the developer himself is responsible for the allocation and release of memory, in Java this task is abstracted from the developer. Although this is an enormous convenience for the developer in later working life, there is a lack of knowledge about what is actually happening in the background for many developers who have only worked with such languages so far. ...

With my LifeCounter app for Magic The Gathering, I released my first Android app on the Google PlayStore over two years ago. Besides my first release, this was also another milestone for me: My first real app. Over two years later, I am proud to announce a completely revamped version of the app. Several complete revisions have taken place in the meantime and I’m already planning the next one, as I admittedly tried to learn the MVP pattern with the app and now, a few months later, I’m completely dissatisfied and want to switch to MVVM. But that doesn’t really matter at the moment. ...

When you’re at the beginning of your career as a software developer, like me, you probably know the feeling that you’re being overwhelmed by everything you want to learn. Especially at the beginning it is often not easy to work productively and to learn why I want to show you which methodologies I have developed for myself. Even though I use my own experience, my approach is of course not limited to the industry. ...

Today I want to show you how to develop your first API with .NET Core. .NET Core is an alternative to the classic .NET Framework. In contrast to the .NET Framework, .NET Core offers a huge advantage: It is platform-independent and therefore compatible with MacOS, Linux and Windows. The purpose of this article is to build a small REST-based API, which will respond to HTTP GET-requests. Of course you can extend the project according to your own ideas and experiment around. ...
