What it does
A Windows 9x inspired operating system written in Vanilla JS where every HTML file is executable.
Sacred OS can boot in three ways: from IndexedDB , from a JSON disk backup , or with a fresh install . If this is your first time using Sacred OS, you will want to boot with a fresh install. Your data is automatically saved to IndexedDB, which allows you to store gigabytes of data. You can boot from IndexedDB to resume where you left off. If you frequently clear your browser's data or want to use Sacred on a different device, You want to boot from a JSON disk backup. JSON disk backups will save your session exactly as how IndexedDB does, but you are able to save it as a file anywhere on your real computer. You can create these backups in the files.html program. No saved session in IndexedDB…from sacred.neocities.org

I wrote a "web OS" based on the Apple Lisa's UI, with 1-bit graphics2025 · alpha.lisagui.com · ▲516https://lisagui.com/info.html This is a web OS I wrote in vanilla JS that looks like the Apple Lisa Office System (1983-85), with other contemporaneous influences and additional improvements and features. It's currently in alpha and isn't remotely bug free. I had been holding off on posting this here until it was somewhat presentable and useful. Please note; the Lisa conforms more literally to the desktop metaphor than most modern GUIs - some of the important differences are mentioned in the readme. This is a complete recreation of the UI in JS; it all renders to a single…

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hey there HN! We’re Joe and Stopa, and today we’re open sourcing InstantDB, a client-side database that makes it easy to build real-time and collaborative apps like Notion and Figma. Building modern apps these days involves a lot of schleps. For a basic CRUD app you need to spin up servers, wire up endpoints, integrate auth, add permissions, and then marshal data from the backend to the frontend and back again. If you want to deliver a buttery smooth user experience, you’ll need to add optimistic updates and rollbacks. We do these steps over and over for every feature we build, which can…
