Pushing Earthly to the Limit

In every project, setting up CI pipelines in a way that is easy to build, understand, and test locally is a constant struggle. Time to test a tool that promises to solve that: Earthly.

Rethinking End-to-End Testing for Web Applications

After years of building web applications across various languages and frameworks, one challenge remained constant—writing reliable end-to-end tests was always a pain. But what if we could rethink E2E testing from the ground up? In an ideal world, how would we test our web applications?

How I Want to Build (Web) Apps

Over the past year or so, I have been tinkering with a lot of ideas involving (web) applications. This post explores some of the opinions that I developed during this time and the conclusions that I am taking from the experience.

Designing My Own To-Do App

For years, I've searched for the perfect task management system. But after countless experiments and iterations, I've decided to take matters into my own hands. Introducing my dream app: Otterdone.

Designing a New Home Server

It's time to set up a new home server! But before jumping into the work, let's take a moment to consider how to manage the server and what to run on it.

Leaving the Cloud

The past few months have made me reconsider my relationship with social media and cloud services. And I think that I'd be happier if I felt more in control over my digital life.

Creating a CLI to Improve My Focus

I am trying to improve my focus and rediscovered the Pomodoro Technique. But because I struggle to form new habits, I decided to make it more interesting by building my own productivity tool.

DEV x BOTS

After years of experimenting with automation and developer tools, I am starting DEV x BOTS to create an automation platform for developers. We all have tasks that could just be automated, if that was easier to do.

Automate Building and Publishing a Game on itch.io

Automated builds are a great way to produce consistent results, and to make a developer's life easier. In this post, I show how to use GitHub Actions to first create a release for a game, and then push that release to itch.io.

Designing an API for a Video Game

I am working on Auto Traffic Control, a video game for programmers. The game is played by writing code that interacts with the game through an API. This post explores the design of the API that connects the player's code, the API layer, and the game simulation.

Auto Traffic Control – A Video Game for Programmers

Auto Traffic Control, fittingly abbreviated ATC, will be a video game for programmers about safely routing planes to an airport. It takes inspiration from the old school hit Flight Control, and adapts its game mechanics for programming.

Four Weeks of Experiments

At the beginning of 2022, I set the goal to experiment with different project ideas and technologies. I want to learn new things and build something, and after four weeks it is time to pause and reflect on the progress.

Day 4 – Adding Tech Debt

Yesterday, I was following along with the book Zero to Production to set up a web server in Rust. Today, I went rogue and added a background job system. All code quality metrics have dropped as a result.

Day 3 – Productive Procrastination

After two days of mostly theoretical work, I felt like writing some code today. So I got my copy of the book "Zero to Production" and worked on the app's web server. As a result, the project is built with Rust now...

Day 2 – Exploring an Idea

Yesterday, I brainstormed ideas for a project that I can build in a few weeks. Today, I am exploring one of those ideas in more depth. The goal is to develop a better understanding of the product and its constraints.

Day 1 – An Empty Source File

The new year is here and I have some time to experiment. It has been a while since I had the opportunity to explore new technologies and build something. I have a few ideas what to do and what to learn, but I still need to figure out the details.

godot-logger – A Rust Logger for Godot

While building a game with Rust and Godot, I wanted to see log messages in Godot's editor. Because I could not find an existing solution, I went ahead and created godot-logger, a crate that prints to Godot's output console.

Fully Automated Dependency Upgrades with Dependabot and GitHub Actions

Dependabot is an app for GitHub that automates dependency upgrades through pull requests. When maintaining many or large projects, manually merging these pull requests can take quite some time. Luckily, the process can be fully automated with the help of one or two GitHub Actions.

Turtles All the Way Down

Four weeks ago I wrote a lengthy post about why I want to build a video game for programmers [https://www.jdno.dev/why-i-want-to-build-a-video-game-for-programmers/]. Since then the foundation for the project has been laid, I joined forces with my good friend Rob, and it is now time to develop the
