Zazen for ADHD devs: what 20 minutes of sitting still does to my brain

Zazen for ADHD devs: what 20 minutes of sitting still does to my brain My brain is loud. I have ADHD. That's the short version. The long version is that my brain runs roughly seventeen tabs at once, half of them muted, all of them unfinished, and any attempt to close one spawns three more. If you know, you know. The thing I was going to do five minutes ago is being narrated over three ...

The Brutal Truth About Capa-Java: After 6 Months of Multi-Cloud Hell

The Brutal Truth About Capa-Java: After 6 Months of Multi-Cloud Hell Honestly, when I first heard about Capa-Java, I thought I'd finally found the Holy Grail. "Write once, run anywhere" – that's what Java promised me back in 2005, right? But here I am, six months later, with bleeding eyes and a frazzled brain, ready to share the unvarnished truth about what it really takes to make a Jav...

What Building a DSL Teaches Us About Constraints

I’ve been working on a domain-specific language for a point-and-click framework called Escoria built on top of the Godot game engine. The original DSL was implemented as a regular language, largely using regular expressions. It was flexible in the sense that it accepted a wide range of inputs, but that flexibility came at a cost. There were very few meaningful constraints. As a result: pre-co...

A Team Member Asked for a Short Break. Then a Much Longer One. Here’s What We Did.

The short break was supposed to fix it. He came to us saying he was dealing with health issues (screen fatigue), the kind that builds up quietly when you’re behind a screen for hours every day with no real separation between work and rest. We talked, we agreed on a short break, and I thought we’d handled it. He’d rest, he’d come back, we’d move on. He didn’t come back. Not then. When he reached...

Symfony Asset Mapper: How to Finally Test JavaScript Properly Without the Pain

You know the drill. Symfony Asset Mapper is a great tool. You've gotten rid of Webpack, npm install, and complex build processes. Everything is fast, cl ean, and modern. And then comes the fateful question: "And how do we actually test this?" Then comes the reality check. Asset Mapper works on the principle of importmap.php, which your Node.js (and thus most test runners) has no clue about. You ...

Why Quantum Computers Are Faster — the Answer Isn't Parallelism

A qubit isn't a bit with randomness — it's a rotating arrow on a sphere. A quantum gate is a rotation of that arrow. A quantum algorithm is one global transformation that reshapes the whole solution landscape. The headline everyone has read in a press release — "quantum computers try all possibilities in parallel" — is dangerously misleading. A measurement would just return one random answer an...
