Terax packs a terminal, editor, git graph, and an AI agent into an 8 MB binary

Terax fits a terminal, a code editor, a git client with a real commit graph, a web preview pane, and an agentic AI panel into a binary that takes about 7 to 8 MB on disk. Most tools that pack that much surface area ship far heavier. Terax gets there by building on Tauri 2 and Rust instead of a bundled browser runtime, and the result is a dev workspace you install without an account and run without...

How to use third party web components - "for the rest of us"

The question Last week I had a chat conversation with a friend who has some basic understanding of what HTML and Javascript is but wasn't familiar with tools and usage from the "modern" JS ecosystem like npm. He wanted to use a third party web component (found on GitHub) in a simple html file. The docs said something like: Installation: npm install @some-author/some-pkg Usage: imp...

How to Self-Host an AI API Gateway With Sub2API

Sub2API can put one Base URL in front of several AI providers and accounts. Your clients use keys that you issue, while the gateway handles authentication, routing, usage accounting, and concurrency limits. Getting the containers online is the easy part. Once the gateway is running, you also own its database, Redis instance, TLS endpoint, credentials, logs, backups, and upgrades. This guide buil...

I built a security layer for applications that developers can install in seconds

Building Defen.so: a developer-first security layer for modern applications Most developers know they should add more security to their applications. A WAF, vulnerability scanning, monitoring, rate limiting, bot protection, file upload checks, security logs... But in practice, security often becomes a task for "later". The problem is that later usually means after something goes wrong. I starte...

Conducting agents like an orchestra: how agents-concerto works

For months I had the same problem with coding agents: the session drops a pile of changes, and by review time I no longer know what it touched or why. The agent writes, the agent validates, the agent congratulates itself. The human signs blind. And when the agent did write tests, it got worse — green tests that proved nothing. Mocks of the very code under test, assertions on private fields, sna...

What I Mean When I Compare the Process to a Quantum State

Claim boundary: I am not claiming that this process is quantum mechanical. My claim is methodological: quantum mechanics supplied a unifying frame through which I could reapproach the inherited ruler–ruled model of human–AI relations and articulate an alternative built from context, interaction, explicit gates, provisional state, durable links, and governed synthesis. I am approaching AI as an ...

How to Build a Custom Debounce Hook in React (Complete Guide)

Modern React applications often make API requests while users type into search boxes. Without optimization, every keystroke triggers a request, causing unnecessary network traffic and poor performance. A custom debounce hook solves this problem by delaying execution until the user stops typing for a specified amount of time. In this guide, you'll learn: What debouncing is Why it's useful How t...

I'm now a maintainer of toofan, here's what I shipped

toofan is Monkeytype, but for your terminal. Minimal, lightweight, zero telemetry, everything stays local. It's sitting at 300+ stars and was recently featured on Terminal Trove.

Last Loot Report was a single day's haul. This one is slower — four lines I lifted over a few weeks, each one aimed at the least glamorous corner of my systems: the checks that were supposed to be watching and quietly weren't. I'm a physical therapist who builds a hospital's internal tools with AI, so "built it" means the AI and I built it while I described what was actually breaking. Every one st...
