Always good to see mobile phones rise during your talk: it usually means your slide contains valuable, practical information. I noticed this whenever I showed my Claude Code configuration slide.
Claude Code offers many options; my setup strips away the ones I don’t need. Here I cover each setting, what it does, and why I changed it.

Have we reached the age of personal software? Have we come to the moment that writing code is democratized, similar to how photography became available for everyone with the introduction of the smart phone? Currently I build what I (think) I need, or just what I like to build.

The power of large language models is of course the ability to generate text. Text can be converted to speech. Why not make an app to practice spelling? In the Netherlands there’s the annual “Groot Dictee der Nederlandse Taal”, a recurring dictation contest happening since 1990. This post is about making a web app with Claude Code using Claude to generate the sentences of the dictation and a text-to-speech service (TTS) to have them spoken aloud. Afterwards, one can review their written result with the actual text used.

Yes! I organized the first Claude Code meetup in Amsterdam ever! Around fifty Claude Code enthusiasts came to an evening all about Claude Code and vibe coding: what can AI do for you when coding? We kicked off with a solid base for future meetups and I’m planning on the next one already!

By accident I came up with a pretty good resonance prompt today. A resonance prompt can be used as a get-to-know-the-model-quickly-prompt: a way to get a quick glance of its capabilities, not only formally but also creatively.

Most AI chat apps of frontier model producers still evolve around simple chats with weak organizational features. I know a lot of development is happening, but Claude, Gemini and ChatGPT mostly stick to the–now already relatively old–“chat” concept of AI agents. This is a pity though, since this way they prove to be model developers instead of application developers. Here’s my chat app improvement wishlist.

Last weekend I gave a presentation on Creative Vibe Coding for the Vibe Coding Lab at NP3 MOBi in Groningen. I contacted my long-term friends at NP3 with the suggestion to organize an event on June 21st, 2025, on the use of AI coding agents for creative people. We had a joyful night of vibe coding with a great audience: they discussed, created, and listened very well.

I recently discovered a neat feature in Anthropic’s Claude Code that I had to share: custom slash commands. I wanted a way to easily tag repository states, and specifically in small projects that do not rely on package.json or similar, by relying on a VERSION file. I decided to dive deep into custom slash commands and create my own semantic versioning command. What I found was a flexible system that has lightened up how I handle routine development tasks.
