Go 1.25 introduces new experimental packages for encoding and unmarshaling of Go types. The new packages are not visible by default and may undergo future API changes. This blog post argues for a new major API version and explains how you can make use of it.

JavaScript is single-threaded but handles multiple tasks concurrently using the event loop, call stack, callback queue, and microtask queue. Getting to know this, lets you write non-blocking code, manage async operations, and build responsive web apps.

SQL practice is boring because you're querying meaningless data in a vacuum. I built SQL Case Files - a detective game where you solve crimes by writing real SQL queries. Your phone vibrates when you close a case. No badges, no streaks, just investigations that feel physical. 15K monthly users in 4 weeks. This is how I made it work technically: SQLite WASM for local execution, result-set validation instead of SQL text matching, mobile-first UX with sticky schemas and bottom-sheet drawers, and a rate-limited AI assistant (20 calls/day because I'm paying for it). The constraint accidentally made people better at SQL. Free to play, no signup, runs entirely in your browser.

I moved my portfolio website from Next.js to Astro after three years. Faster builds, less JavaScript, better SEO, and a simpler setup that just works.

Next.js was too much for what I needed. Astro renders pages to static HTML and only sends JavaScript to the browser when you explicitly ask for it. Astro’s biggest win is how little JavaScript it ships by default.

This article traces the evolution of modern code review from formal inspections to tool-driven workflows, maps key research themes, and highlights a critical gap: how practitioners actually perceive and use MCR research. By pairing a systematic literature review with a practitioner survey, it surfaces where academic focus aligns—or clashes—with real-world software development practice.

In a microservices world, your API *is* the product. Bad API design isn't just ugly code; it's architectural entropy. The "Contract-First" Enforcer forces Large Language Models to stop being "code generators" and start being "specification designers"

The symfony/workflow component has long been one of the framework’s most powerful, yet underutilized, gems. It allows developers to decouple business process logic from entity state, transforming complex “spaghetti code” status checks into clean, visualizable directed graphs. In this article, we will build a robust Multi-Signature Approval System for a FinTech application. We will explore how to configure weighted transitions, implement the entity logic, and verify the flow with rigorous testing.
