People check the https://github.com/GreenteaOS/Greentea which currently contains binary assets. This repo will have user-space apps sources. Currently sample apps are taken from ReactOS project.

The code is mostly in the https://github.com/GreenteaOS/Tofita and https://github.com/GreenteaOS/Caramel

Greentea OS is built from scratch in a custom programming language Hexa with custom kernel design (called Tofita Engine)

While the language looks pretty high-level, having a custom language allows us to fine-tune it for the needs of the OS. It was intended for games and game engines, but later I extended it to the osdev too. The design of Hexa implies balance of high-level feel and moderate safety by default without compromise on performance. You may always go lower or higher level when needed. Kernel is a game-engine inspired experimental design. For simplicity, you may assume its a monolith (with some internal sandboxing, but that's not yet fully implemented). I will cover Tofita design in the future as it evolves.

Greentea OS is an alpha-stage GPL3 desktop OS from scratch that boots on x64 UEFI devices, and runs existing software unmodified (currently supports .exe files). The goal is to create a fast, lightweight OS that competes in the operating system space.

That's what I expect from upcoming Oblivion remaster. Very lovely!

Your eye muscles maybe just tired from constant staring, or neck tension causes brain blood flow problems or something. I struggled with this all the time, but supplementation and exercise helps a lot.

Technical papers aren't THAT boring, after all!

Seems like its completely different person with the same name of Rafal Kupiec. Pretty common Polish name and surname. WinuxOS is not related to ExectOS by any means. The post is from almost 20 years ago.

Also I don't see that level of code similarity you're claiming. KeLowerRunLevel in Minoca is literally a one liner. Most functions behave differently compared to Minoca's. I've asked Belliash on Discord, he was reading Minoca to derive some inspiration. And Codeium AI autocomplete may sometimes generate code similar to other projects. Nothing to worry about.
