NodeBook
Master backend engineering through Node.js
What it does
The first two volumes of NodeBook are complete and free to read online. Volume 1, The Node.js Runtime, goes deep on the architecture, event loop, buffers, and streams that everything else sits on. Volume 2, Networking & Protocols, covers TCP, HTTP, sockets, DNS, and TLS down to the internals, not just the API surface. Every chapter pairs with runnable Node Runtime Labs, plus EPUB, PDFs, slides, and cheatsheets. Two volumes down, five on the way.

Colin here, creator of Nub. I’ve had the general shape of this in mind for years. Nub runs your code with stock `node`, augmented with a `--require` preload hook[0] that adds a transpiler (oxc-powered, packaged as a Node-API add-on), registers a module resolution hook[1], and injects polyfills as needed for APIs like `Worker`, `Temporal`, etc. All purely additive, your code ultimately runs using Node’s actual engine & stdlib implementations.

Hi HN! Thanks for your attention to my post. It was a big challenge to run most of Node.js packages in browser, fast moreover. Virtual File system, resolve import/export. I got cold many times, depressions, burned out, yet still alive and finished it. Many guys helped me with an advice. Many users give a lot of positive feedback. There are 200,000 monthly unique users. I work full time now because of the freemium business model. To be honest - I am happy after many years of hard work.

Srcbook (”source-book”) is an open-source TypeScript notebook that runs locally, powered by Node.js. It shines for rapid prototyping, code exploration, and collaborating on ideas. It’s inspired by Python’s Jupyter and Elixir’s Livebook. Key features: - Full npm ecosystem access - AI-assisted coding (OpenAI, Anthropic, or local models), it can iterate on the cells for you with a code diff UX that you accept/reject for a given code cell, generate entire Srcbooks, fix compilation issues, etc… - Exports to valid markdown for easy sharing and version control Try it now: `npx srcbook start`…

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…
