A while ago, I wrote this article about a simple implementation of an Arcball camera in C++. In it, I described how that could get done without using Quaternions, spherical coordinates, or a lookAt function. Anyway, just out of curiosity, I decided to create a minimal implementation of an orbiting arcball camera in C# using spherical coordinates.Continue reading How to program an arcball (orbiting) camera in Unity using spherical coordinates
Console applications are a great thing: They usually solely focus on getting things done. That, however, often also means that the user experience can come short. While I don’t have a problem with a simple text-only menu, it can often scare away new users. But there’s a way to easily style your console applications so that they can have something that you could call a primitive GUI:Continue reading Write better looking console applications using ANSI escape codes
I managed to send video signals to a Mac Classic’s internal CRT monitor from a BeagleBone Black back in 2016, and it seems like this is a topic that a lot of people are still interested in. A recent discussion gave me the idea to try and do the same thing with a Raspberry Pi, and I wanted to document the experiment in this article.Continue reading Control a CRT with the Raspberry Pi DPI
I discussed Java Lambda Expressions quite a time ago in another article. Those were not the only new thing that got implemented in Java 8. Besides Lambdas, Type-Annotations, and Default methods in interfaces, version 8 of the Java API added support for functional-style operations. Because I think that this is quite a rarely discussed feature, I decided to write this short introduction to the Java Stream API and how it can be used for basic functional-style programming in Java.Continue reading Functional-Style Operations in Java with the Stream API
I needed to implement a function that allows users to dynamically switch between different themes in an app that I develop at the moment. As the title suggests, I use Angular Material components and Material themes.
In this article, I’ll give you a step-by-step guide on how you can choose between different themes in an Angular app dynamically.Continue reading How to implement switchable dynamic custom themes with Angular Material
Just like the snow in GTA Online, the annual Christmas letter on nerdhut is back! This year was the best one so far for this website, which means that this streak goes on since 2016. Let me quickly go over some facts for this year and highlight some goals, that got achieved in 2019!Continue reading 2019: The annual Christmas report
