Swagger docs from your existing TypeScript types — no framework required

The problem Recently I was looking for an npm package to generate OpenAPI (Swagger) documentation for my existing TypeScript project. My biggest requirement was TypeScript type-to-schema conversion: I already have all my request and response types, so why should I maintain the same schemas again in OpenAPI? Zod support would be a nice bonus. After trying most of the existing solutions,...

I Built 50 Browser Games Without React. Here's Why.

When I started building GamesMom, my goal wasn't to create another gaming website. I wanted to build a collection of browser games and educational games that children could play instantly without downloads, sign-ups, or apps. Today, GamesMom includes more than 50 HTML5 games covering math, memory, typing, puzzles, word games, and classroom activities. One decision surprised many developers. I d...

minikube with the Docker Driver on Ubuntu: A Practical Local Cluster

minikube is the other "Kubernetes in Docker" option on Ubuntu, and with --driver=docker it runs the cluster inside a Docker container just like kind — but ships with addons (ingress, metrics-server, dashboard, a built-in registry) that make it feel more like a real cluster. Here's a practical setup and how it differs from kind. Install on Ubuntu You need Docker first (sudo apt-get inst...

Best AI Model for Unreal Engine in 2026? Kimi K3 vs Claude Opus 5 vs Qwen3.8

Evidence checked on July 25, 2026. This comparison separates vendor claims, general coding evidence, and native Unreal Engine delivery. Those are not the same thing. Kimi K3, Claude Opus 5, and Qwen3.8-Max-Preview all arrived with unusually strong claims around coding, visual iteration, long-running agents, or 3D creation. That makes one question inevitable for game developers: Which AI model i...

Has an API ever silently changed its response shape and broken your app before you noticed?

I keep running into (and hearing about) a specific kind of bug that never throws an error — an API you depend on quietly changes its response shape. A field disappears. A number becomes a string. Something that was always present is suddenly null. Nothing crashes immediately. It just produces wrong or missing data somewhere downstream, and you find out from a bug report, not a log. I'm curious ho...

How I compile React-shaped TSX without React or hydration

I started building Kudzu while making static websites with AI. AI coding tools have become very good at producing React-shaped TSX, and I have become used to reviewing code in that form. Function components, props, JSX, and event handlers are often easier for me to understand and verify than scattered DOM queries and imperative JavaScript mutations. But I was still building static pages. I want...

Architecting RoutePe Auto: Building a Scalable Transport Management Software with Laravel, React, Flutter and MySQL

Modern logistics is built on time-sensitive operations, yet traditional freight procurement suffers from friction. Legacy systems depend heavily on fragmented offline negotiations, opaque spot market prices, manual Lorry Receipt (LR) tracking, and coordination gaps between warehouse controllers and field drivers.To eliminate these operational bottlenecks, RoutePe Auto was engineered as a high-thro...

Keeping state (connections) alive with Cloudflare workers

At work I built a custom datastore / multimodel database on top of io_uring and Rust, which I would like to expose to the public via Cloudflare workers. Unfortunately there is a cost in setting up a new connection to the backend from a cold worker, cost which I'm trying to amortize very much like Hyperdrive does for SQL databases. I imagined a solution like placement groups: - I spin up a durable ...

Building my first website was exciting, but it taught me that creating something people actually enjoy using is much harder than just writing code. Here are the biggest mistakes I made and what I learned from them. Trying to Make Everything Perfect I kept changing tiny details instead of launching. Lesson: Ship first, improve later. ⸻ Adding Too Many Features I focused on building more ...

AI Agent Sandboxing: Contain the Blast Radius

AI agent sandboxing means running an autonomous AI agent inside an isolated, contained environment. No network by default, scoped and short-lived credentials, a locked-down filesystem, resource and budget caps, disposable infrastructure. Whatever the agent does, including a mistake or a hijacked instruction, stays inside the box. The alternative is to bet your safety on a human noticing the wrong ...

cargo-witness: verify a published Rust crate matches the exact commit it claims

When you review a Rust dependency on GitHub, you are reading its source. When cargo build runs, it compiles the .crate artifact downloaded from crates.io — a separate upload. Those two are not guaranteed to be the same bytes, and nothing in the normal workflow checks that they are. That gap is exactly what the onering attack (June 2026) used: a malicious build.rs build script was slipped into the...

Why AI understands formal Arabic but gets lost in dialects

Ask an AI chatbot a question in formal Arabic (Fusha) and it answers beautifully. Ask it the same thing in Gazan, Egyptian, or Moroccan dialect — and it stumbles, mistranslates, or misses the point entirely. As someone building an Arabic AI newsletter, I run into this every day. Here's what's actually going on under the hood — and why it's a great window into how large language models really work...
