Compound Components are great, but should be type-safe. No, this isn't about the children prop ...

Steal any component from a production React website without source code - using React Fiber and LLMs to reconstruct working components.

Streaming JSON in just 200 lines of JavaScript / I was continueing my exploration of React server components when I stumbled upon on this article about progressive JSON. Dan Abramov describes a technique for streaming JSON from a server to a client in chunks, allowing the client to start rendering parts of the data before the entire payload has been received. This can significantly improve perceived performance, especially for large datasets. So, I started wondering how much of an effort it would be to implement something like that. It turned out a fun exercise, and I ended up with a small (200loc) library called Streamson. So, this post is about how I built it.

Use promises to provide data from Server Components to the client tree, without blocking the rest of the page.

We've encapsulated 10+ years of React and Next.js optimization knowledge into react-best-practices, a structured repository optimized for AI agents and LLMs.

What’s one of the biggest challenges with using AI for QA? It’s the lack of programmability. We set out to find a solution by pairing Playwright MCP with several different LLM models. Find out where we landed.

OpenAI is partnering with Cerebras to add 750MW of ultra low-latency AI compute to our platform.

Markdown Reference This document is the comprehensive reference for Markdown support in RDoc. It covers all syntax, extensions, and formatting option

RDoc has always supported Markdown as a markup language. But its support was buggy and lacks documentation. After a year of addressing various related issues, I was able to rewrite a doc for it. I think we'll soon be able to migrate from RDoc to Markdown. https://ruby.github.io/rdoc/doc/markup_reference/markdown_md.html

I'm routinely asked about "automatic N+1 solving" libraries for Rails, which essentially try to manipulate `includes()` calls for you. I don't recommend them. IME, missing `includes` is only ~10% of the actual N+1s I see in the wild. And, includes() isn't always optimal!

Instead of writing code comments that decay and mislead, let LLMs generate documentation on-demand and fail the build when code is too obscure for them to explain.
