Symfony Messenger: A Great Servant, But a Terrible Master (Or How Asynchrony Cost Me Half My Beard)

I am a long-time Symfony developer. I love the framework. I use it in countless projects—whether they are large corporate systems, smaller work tasks, or my own private pet projects. When the Symfony Messenger component was introduced years ago, I instantly fell in love with it and deployed it pretty much everywhere. Everything worked like a Swiss watch. At least, that’s what I thought... until r...

How Matrimony Platforms Are Using Astrology APIs to Improve Match Quality

In India, the question "what's your kundali score" still gets asked across millions of marriage conversations every year. It is not a fringe ritual. For roughly 80% of Indian families involved in arranged or semi-arranged marriages, kundali matching is a non-negotiable step before two families seriously discuss compatibility. The Indian matrimony market is a multi-billion-dollar industry, and the ...

Selenium vs Playwright in Java — A Practitioner's Comparison

Selenium vs Playwright in Java — A Practitioner's Comparison By a QA Engineer with 10 years in Selenium, now hands-on with Playwright I didn't switch to Playwright because it was trending. I switched because a Shadow DOM component broke my Selenium suite for the third time in a week, and a colleague said, "just try it." That was the beginning of a humbling, then genuinely exciting, ...

I Built an Open Source Directory for Devs Because Discovery is Still Broken in 2026

There are more open source tools than ever. GitHub has hundreds of millions of repositories. And yet, when you need a specific tool — a self-hosted analytics platform, a lightweight CMS, a developer productivity tool — you still end up in the same 12-tab rabbit hole of outdated blog posts and stale Reddit threads.

When a powerful tool is built for engineers but needs to work for everyone else, the design is not a cosmetic layer – it is the product. By Isaiah Udoh UI/UX and Graphic Designer, UK There is a category of software product that most UX designers rarely think about when they are starting out, but that they encounter constantly once they are working inside real organisations.

If you look at the query logs of any production AI application at scale whether it is a customer support bot, an internal knowledge assistant, or a coding copilot you will notice a glaring pattern. Humans are overwhelmingly predictable. User A asks: "How do I reset my password?" User B asks: "Forgot password help." User C asks: "Where is the password reset link?"

How I built a 3D space simulator in one day with Claude (Three.js + shaders)

I'm not a graphics programmer. I had never written a GLSL shader. I'd heard of Three.js but never actually used it. One day later, aethelia.space exists — a browser-based 3D space simulator with 6 real star systems, 12 shader-rendered cosmic anomalies, moons orbiting planets, procedural textures, and ambient audio. I built it pair-programming with Claude (Anthropic's AI). This post is the honest...

The Zero-Knowledge Trap: Why ownPublicKey() Cannot Prove Identity in Compact

For everyone who has ever written Solidity before, you should know this pattern: require(msg.sender == owner, "Not the owner"); It works because the EVM cryptographically verifies the transaction signature. The protocol proves the sender knows the private key, so identity verification is free. When developers arrive at Midnight and discover ownPublicKey(), the instinct is similar, like w...

Faru: The Kanban Board for AI Agents

A few weeks ago, we replaced Jira with a folder of markdown files. We've coined it faru and we've been using it every day since. It stuck. So we put it on GitHub. Why we built it It's not that we built a tool to give our AI agents a backlog. It's about AI agents making their work visible to us. Our agents write markdown files into a backlog/ folder in our docs repository. A bit like p...
