Data Validation Using Early Return in Python

While working with data, I find validation logic tends to get messy faster than expected. It usually starts simple then a few more checks get added, and suddenly everything is wrapped in nested if statements. That pattern works, but it doesn’t feel great to read or maintain. That's how I learned...

Microlearning for developers: learn new concepts in 15 minutes

Developers are expected to keep up with an industry that never slows down. New frameworks, languages, and tools appear every few months, and falling behind even slightly can feel overwhelming.

ServiceKit V2 — The Async Service Locator for Unity

I just shipped V2 of ServiceKit, my lightweight dependency management package for Unity. Before I get into what's new, I want to address the thing some of you are already typing into the comments: yes, ServiceKit is a service locator. On purpose. I think that's the right shape for Unity, and V2 is w...

I built an accessibility compliance SaaS in a day with Claude Code

TL;DR — I'm not a primary coder. I spent ~12 hours on Saturday with Claude Code and shipped axle: an accessibility compliance CI that scans every PR for WCAG 2.1/2.2 AA violations and proposes AI-generated code fixes. It's live on GitHub Marketplace, npm, and a hosted web UI, and processed its first...

How to Build an AI Vocal Remover in Python with the StemSplit API (2026)

I needed to add vocal removal to an app last week without shipping a 300 MB Demucs model with the binary. The shortest path I found was StemSplit's API — three endpoints, one model (HTDemucs), and a free tier big enough to prototype on. This is the working tutorial I wish I'd had. Single file, batc...

AI Vocal Remover Benchmark 2026: 6 Tools Tested with Python (SDR + Speed)

A vocal remover is just a stem separator with the "everything except vocals" output thrown away. So why does picking one feel hard? Because the quality gap between tools is huge — bigger than the marketing pages let on — and almost nobody publishes numbers. I needed an answer for a side project, so...
