https://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…

This is my operating system that I've been working for the past 2 years. All of the code is written exclusively by me except from ported software. banan-os has a monolithic kernel targeting x86 (i686) and x86_64 architectures. The project consists of bootloader, kernel and userspace libraries (libc, libGUI, libFont, ...). It also uses my custom C++ standard library partly based on stdc++. Currently I have basic TTY and GUI environment with some of the basic UNIX utilities like cp, ls and stat. I have basic support for USB (keyboard/mouse/storage), disks (NVMe, AHCI), custom…

Finally got my hobby OS up and running on real hardware. I love the old IBM thinkpads, so thought it was the perfect machine to get it working on. Been working on it for quite some time now, but this has been a big milestone!

Hello HN! Showing off the first version of Munal OS, an experimental operating system I have been writing in Rust on and off for the past few years. https://github.com/Askannz/munal-os It's an unikernel design that is compiled as a single EFI binary and does not use virtual address spaces for process isolation. Instead, applications are compiled to WASM and run inside of an embedded WASM engine. Other features: * Fully graphical interface in HD resolution with mouse and keyboard support * Desktop shell with window manager and contextual radial menus * PCI and VirtIO…

Hi HN, I’m Dvir, a young developer. Last year, I got rejected after a job interview because I lacked some CPU knowledge. After that, I decided to deepen my understanding in the low level world and learn how things work under the hood. I decided to try and create an OS in C and ASM as a way to broaden my knowledge in this area. This took me on the most interesting ride, where I’ve learned about OS theory and low level programming on a whole new level. I’ve spent hours upon hours, blood and tears, reading different OS theory blogs, learning low level concepts, debugging, testing and working on…
