Explore hobby operating systems on OSHub. 100+ users and 70+ projects online. Browse by architecture/language/stage, follow devlogs & releases, and even boot some OSes right in your browser (v86.js). oshub.org #osdev #hobbyOS #kernel

In kernel space, a use-after-free doesn't crash your program. It crashes everything. Why Rust changes that, and what unsafe actually means at the kernel level: oshub.org/users/OSHub/po… #osdev #rust #kernel #memory

@ChShersh Or just a nerd for retro programming. :D

If someone wanted to get better at C systems programming this year, what should they focus on first? #systems #programming #engineering

If you are building a small OS in C today, where would you use AI in the workflow: debugging, driver development, documentation, testing, or would you even use it at all? #osdev #c #ai

@dywoqq Impressive!

Kernel is successfully loaded by bootloader, and it outputs white color. I'm going to continue tomorrow to finish memory maps, and the boot loader will be officially completed. #rustlang #OSDev #aarch64

@pachisonlab Very cool!

🎉 Just jumped in without much planning, but built a basic OS in 20 days! ✅ Memory, processes, files functional. Great learning experience! Next project awaits! 🚀 🤖 Made with Claude Code github.com/sironerit/clau… #OSdev #ClaudeCode #20DayChallenge #AI

Simple compiler for nusaOS. A very experimental compiler and VM for my own language, Nsa Lang. oshub.org/projects/nusao… #oshub #osdev #c

@ShowwaiY Very cool!

Starting a Mini OS project! 💻 In an era where AI handles the heavy lifting, I feel it's a privilege to spend time coding line-by-line to understand CS fundamentals. Aiming to finish by March and run it on a RISC-V board. #BuildInPublic #OSDev #RISCV #Coding

@IkhanobaShaka Nice!

Developing a microkernel OS from scratch (Rust🦀) targeting x86_64, RISC-V, AArch64, with early GPU/NPU & accelerator work. Seeking serious OSDev collaborators. github.com/Splax-s/splax_… #OSDev #KernelDev #Microkernel #RustLang

@t1b4n3 Very interesting!

learning how bootloaders work, and writing my own x86 bootloader completely from scratch. I’m also exploring how bootloaders get exploited, how attackers abuse early-boot trust boundaries, and what secure boot tries to prevent. #Assembly #x86 #osdev #CyberSecurity

@jbzfn Really interesting!

@skyvlan Wow thats really impressive! Good job!

Hey everyone! i was inspired by a video about tetris on bare metal so i ported the NES's Super Mario Bros to x86 compatible PCs by statically recompiling the 6502 Assembly code into native code #osdev #NES #SuperMarioBros #emulation #x86

Been looking at Limine lately, it’s a modern bootloader written in C, and perfect if you’re hacking on a hobby kernel / OS. Modern, portable, BIOS + UEFI-friendly, and pretty flexible about how you boot. oshub.org/projects/limine #osdev #oshub #limine

@NovixManiac @orangepixunlong Looks great!

First look: Novix OS Desktop on RISC-V 🚀 After a few weeks of quiet building, here’s our first graphical desktop running on Novix OS: window server, framebuffer, BMP background & cursor. Hardware tests coming up next. @orangepixunlong #RISCV #OSDev #OpenSource
