I built a visual TUI for Homebrew with React and Ink

Why I built Brew-TUI If you're a macOS developer, you probably use Homebrew every day. But memorizing all the brew commands gets old — especially when you just want to see what's outdated, upgrade a few packages, or check if a service is running. So I built Brew-TUI: a full visual terminal UI for Homebrew. What it looks like It's a keyboard-driven TUI built with React 18 + ...

Lifetime subscriptions don't mean what you think they mean

You see a tool you like. It offers a "lifetime deal" for $59. Pay once, use forever. Sounds great — until "forever" turns out to mean 18 months. The uncomfortable truth: in nearly every Terms of Service, "lifetime" refers to the lifetime of the product, not yours. And products die all the time. Here are 11 real examples of what happens when lifetime deals end early. The graveyard of li...

# Pre-Execution Gates: How to Block Before You Execute (Part 2/3)

This is Part 2 of a three-part series on AI governance architecture. In Part 1, we explored why signed receipts can't solve the negative proof problem—the challenge of proving that unauthorized actions didn't happen. Today, we'll examine the architectural pattern that does solve it: pre-execution gates that evaluate governance policy before any AI execution occurs. Note: This series explores arch...

OpenClaw Burned $5,600 of API Credits in One Month. Here's the Spec Habit That Prevents It.

The formula was exact. The assumption was wrong. I was building vectorize-mcp-worker — a semantic search system on Cloudflare Workers that costs $5/month where alternatives run $130-190. The architecture was clean. Workers AI for embeddings, Vectorize for the index, one Worker handling everything at the edge. I'd spec'd the core search flow, written the populate endpoint, deployed it. Everything ...

I needed to understand a large legacy .NET codebase — so I built a tool for it

I’m a .NET dev, and lately I’ve been slowly open-sourcing some of the small things I built for myself over time. This is one of them. The context I’ve been working on an old .NET 4.6 app recently (~15 years old, 1M+ LOC). At some point I needed a way to understand the architecture better. Not in a “read the code” sense, but like: what depends on what where things are going in th...

The exact error handling pattern I use in every Express.js + TypeScript REST API

The exact error handling pattern I use in every Express.js + TypeScript REST API

Most Node.js error handling tutorials show you try/catch. That's not enough for production. I learned this the hard way. A silent catch block swallowed a database failure. My API returned 200. The user's data never saved. Nobody knew for 48 hours. After that incident, I built a pattern I now wire into every Express + TypeScript REST API I ship. It has four parts. Every part earns its place. Here'...

How do I make my JEST scripts, runnable in NodeJS, compatible with Bun if I am using BabelJS transform from browser into NodeJS-compatible JavaScript?

How do I make my JEST scripts, runnable in NodeJS, compatible with Bun if I am using BabelJS transform from browser into NodeJS-compatible JavaScript?

So, in my project, I am using this babel.config.js file to convert from browser-compatible JavaScript into NodeJS-compatible JavaScript before running my JEST tests: module.exports = { presets: [['@babel/preset-env', {targets: {node: 'current'}}]], plugins: ['babel-plugin-rewire', 'export-toplevel'], }; And it works if I try to run npm test. However, if I run bun test, I get the following...

Delete the repo. Question my life choices. It felt inefficient. Wasteful. Slow. So I built something to fix it. 🚀 Introducing GetGrabKit GetGrabKit is a Node.js CLI tool that l...

AI coding agents ship features faster than ever, but the humans inheriting that code can't explain how it works. Addy Osmani calls it "comprehension debt." The data backs it up: pull requests up 20%, incidents up 23.5%, maintenance costs at 4x by year two, and 45% of AI-generated code carrying known security vulnerabilities. 36 quotes from Karpathy, Willison, Osmani, Hightower, Fowler, MIT researc...
