Weenix Kernel — Demonstration

This repository showcases the results of my work on Weenix, a Unix-like toy kernel.
We (Group of 2) implemented this toy OS as part of the semester long Kernel project of the course CSCI402 at USC.
The source code is not included (per course policy), but can be shared privately upon request.
Here you can find screenshots, recordings, and explanations of the kernel features.
