iiinova — where your digital self keeps evolving

Peter van Vliet @petermasking.bsky.social · 24/09/2026

The 14th and 15th of October, @basmasking.bsky.social and I will be back in Trondheim for the 2026 edition of #Containerkonferansen ⭐ After giving a talk there last year, we've been invited back to give our new hands-on workshop: Building Schrödinger's App! Really looking forward to it!

Peter van Vliet @petermasking.bsky.social · 03/04/2026

Exactly three week ago, I shared how we significantly simplified the code of one of our applications by using 𝟴𝟴% 𝗹𝗲𝘀𝘀 𝗼𝗯𝗷𝗲𝗰𝘁-𝗼𝗿𝗶𝗲𝗻𝘁𝗲𝗱 𝗰𝗼𝗱𝗲, presenting it on a big cinema screen at Webdevcon and the Dutch PHP Conference. It was a blast!

Jitar has many similarities with .NET Aspire indeed. I would describe the core difference as follows: With Aspire you build a microservices app that can be run as a whole on your machine. With Jitar you build a (modular) monolithic app, that can be run as microservices in production.

Peter van Vliet @petermasking.bsky.social · 03/03/2026

Happy to see that you liked the talk! It was a pleasure to have you. You're questions where very helpful. Jitar is indeed JS (and TS) only, but the principles and mechanisms can also be applied in other technologies. I've written an article series explaining them and how Jitar implements them.

Just attended an interesting talk by @petermasking.bsky.social at #Basta. They built a tool (Jitar) that can let you develop as a monolith, and deploy in Kubernetes in production. I think it's JS only, interesting nonetheless. github.com/MaskingTechn...

In less than three weeks, I'll be speaking at BASTA! – the conference for .NET, web, and AI innovation. 🎉 And what better talk to give than our Schrödinger’s App, which can exist in both a monolithic and microservices state simultaneously. I'm really looking forward to it! Will I see you there?

Beyond architecture, the programming paradigm we choose shapes how easily we can write, maintain, and evolve code. In the article, I share a simple, rule-based framework we use to blend paradigms for creating code that’s easy for humans to understand and maintain, yet ready for AI support.

I love abstractions, but I also fear them. Good ones reduce complexity, while bad ones add it. Telling them apart isn’t always easy, so avoidance is the widely accepted guideline. Since I couldn’t find a practical, unified source, I decided to create one. levelup.gitconnected.com/cut-the-abst...

My very first "vibe coding" experience was actually better than expected. I only needed 4 prompts to make it playable: 1. Can you build a simple web-based Tetris game? 2. When I start the game, nothing happens. 3. The input is very slow. 4. The bricks get stuck above the bottom. #cursor #ai

My role as a Lead Low-Code Developer places me in a position where I often have to say “no” to certain requirements. By its nature, a low-code platform is opinionated and doesn’t allow for the inclusion of all possible requirements. In my experience, you can meet around 70-80% of the requirements.
