I Built a Pocket OS with JavaScript, Electron, and Gemini
Welcome, traveler, to a new era of digital sovereignty. Oopis-OS has always been about crafting your own world. Now, with Pocket Oopis-OS 3.6, that world is no longer tethered to a single machine. This isn't just an update; it's a fundamental shift in architecture. We've transformed Oopis-OS into a single, self-reliant application that you can carry in your pocket. It asks for no installation, it leaves no trace, and it keeps your entire environment—your files, your settings, your history—right beside the application itself. The obstacle was dependency. The way is self-containment.

I've built a thing! A few months back someone (not me) posted my Mac app Droplings to HN. It was incredibly rough around the edges back then, and in alpha. Well, it's finished now and sparkles like crazy. Please take a look! :)

- IBI built an open-source kernel for Texas Instruments calculators2014 · ▲20
You know that old TI calculator you used in high school, then put in a box and forgot about? Have you ever wished you had an operating system for your calculator with preemptive multitasking, dynamic memory management, a tree filesystem conforming to the FHS, and all the comforts of Unix? Well, good news: that's totally a thing that exists. I've been working on my kernel for about three and a half years now and I'm looking for new contributors to help out. It's written entirely in z80 assembly, and it's both challenging and fun to work on. There's an IRC channel for contributors or people…

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

Today marks ten years, 3653 consecutive days, of running at least one mile every day under the USRSA rules [1]. To celebrate, I built an interactive dashboard that turns a decade of GPX files into charts you can explore. Running has truly changed my life: I've made lifelong friends, explored beautiful places, and more importantly invested into my own health and fitness, which I'm starting to see the positive benefits as I get older. The stack is pretty simple: a NextJS app, with a Postgres database to keep all my running data, and all the stats are pre-computed and cached in Redis, so I…

Made this website as an exercise in vibe-coding and GCP. It was posted about a few times around the internet, on sites like Morning Brew (https://www.morningbrew.com/issues/business-buzzkill), MetaFilter (https://www.metafilter.com/209703/Draw-A-Fish), boingboing.net, etc. I think it's cute! I built a basic CNN trained against penises and swastikas, and then anything that doesn't hit the 63% confidence score gets sent to a mod queue, a vibe-coded fish-tinder…
