node_modules is Why Your Mac is Full: Find and Delete All of Them

I had 47 node_modules folders totaling 38GB on my Mac. Most of them were for projects I hadn't touched in months. A weekend tutorial from last year? Still has its node_modules. That side project I abandoned after two commits? node_modules. A cloned repo I opened once to read the source? You guessed it — node_modules. If your Mac keeps telling you the disk is full and you're a JavaScript developer...

My worst Claude Code sessions – and what they taught me

Everyone talks about how much time AI saves. True. But nobody talks much about the hours you lose to AI mistakes. I've been using Claude Code daily for months. My workflow has fundamentally changed, I'm faster, I ship more consistent code. All of that is true. This article is the counterpart – the moments where I sat at my terminal thinking: "What on earth did that just do?" Not to bash AI. But ...

Homebrew, Gradle, and the Hidden Caches Eating Your Mac's Storage

Most developers know about the big offenders — Xcode's DerivedData, Docker images, node_modules. But there's a second tier of caches that almost nobody thinks about: Homebrew downloads, Gradle wrapper distributions, Maven repositories, Go module caches, Ruby gems, and IDE workspace storage. None of these is massive on its own. Homebrew might be 3GB. Gradle caches, 8GB. Your IDE's workspace storag...

Generative colors with CSS

I just updated the CSS for my website to use a fork of Kelp UI, which includes a much more consistent and easy-to-maintain class system than I had before. Quick aside: if you see any bugs in your travels, please let me know! While it mostly looks the same as before, the biggest change was to the color palette. I’m now taking advantage of relative colors with the oklch() CSS function to dynam...

The Coliseum of Intelligence: Benchmarking the Future with Synapse-AI-Arena and Google Cloud NEXT '26

The Core Problem: Who is the Best Agent? In my project, Synapse-AI-Arena, I’ve been fascinated by a single question: How do we objectively measure the performance of AI agents when they interact in a dynamic environment? I built the Arena to pit agents against each other in structured tasks, measuring everything from latency to reasoning accuracy. Watching the Google Cloud NEXT '26 keynotes, it’...

GitHub Copilot’s Secret Price Increase: Annual Subscribers Facing Up to 27X Cost Multiplier

Annual subscribers face dramatic cost increases as GitHub shifts Copilot pricing multipliers from June 1, 2026.Starting from June 1, 2026, GitHub is pulling back the curtain on a seismic shift in how Copilot charges annual subscribers. What was once a predictable pricing structure is transforming into a tiered cost model based on AI model selection — and the numbers are staggering. Some models wil...

Encrypting agent traffic with zero external dependencies: X25519 + AES-256-GCM in pure Go

Every encryption library is a dependency. Every dependency is an attack surface. When Heartbleed was disclosed in 2014, it affected an estimated 17% of all TLS servers on the internet. Not because the underlying cryptographic algorithms were broken, but because of a buffer over-read in a widely imported C library that most projects had never actually audited. Then in 2024, the xz Utils backdoor s...

The key requirement was to avoid static assumptions and instead learn “normal” traffic behavior continuously.

How I Use AI Agents to Maintain a Living Knowledge Base for My Team

For the past six months, I've been running an experiment: instead of asking my team to write documentation, I asked an AI agent to listen. The result is a living knowledge base — not a static wiki that rots after two sprints, but a system that updates itself as we work. Here's how it works, what broke, and why I think this is the future of team memory. The Problem: Documentation Dies in...
