Greetings fellow nerds. What kind of Kernel Architecture would you choose if performance, simplicity and robustness are the goal? #coding #osdev

#OSDev #ModularOS #Security #Rust #Portability
The shift toward modular, portable OS stacks like Genode and Moss highlights the move from bloated kernels to lean, secure systems. Portability across x86, ARM, RISC-V, and safety through isolation and verification tools are key. Embrace modularity, use Rust for safety, and prioritize compatibility for long-term software maintenance.

I've been working on a custom Arch Linux-based ISO named ARISU (Aeri's Recovery ISO with Superfluous Utilities)
Where other Linux nerds make their own post-install rice scripts, I make a whole ISO instead >:3

Getting started with a cool new project: building my own minimalist Linux OS for x86_64 using Buildroot! 🛠️

Just finished the full cross-compilation with the pc_x86_64_bios_defconfig. The resulting tiny system is up and running in QEMU.

Excited to spend the next few days exploring Buildroot's potential, from custom kernels to package management. Time to dig into the embedded world! 🚀

project introduction: Nitron (https://github.com/mesyeti/nitron)

Nitron is a virtual machine + OS (although I haven't run it on bare metal yet, but I plan on doing very very soon)

the idea is to allow using microcontrollers as personal computers (starting off by targetting the raspberry pi pico, and the bbc microbit v2)

all programs are JIT compiled to bytecode when they are run, from an assembly language heavily inspired by uxntal

the assembly playground you see below is like a REPL for the VM's assembly language

if you want to talk about it, join me on IRC at #nitron on irc.nouveau.community, or in https://discord.gg/38U2EgA8xg
