🔥🚀 Oh, behold! Yet another heroic attempt to revive the ancient relics of *vintage* PCs with #GentleOS. Because, clearly, the world desperately needs more hobby OSes to *not* run Fortnite on your grandma's dusty 486. 🙄💾

🤖🎉 Look out, world! Another brave soul has achieved the Herculean task of running a C++ web server on their ultra-exclusive hobby OS that precisely three people will use. 🌐🥳 But don't worry, it only took a minor eternity and a GitHub repo no one will clone. 🙈🙌

An Elf Odissey! #dreamos64 I recently added support for basic ELFs in my hobby #kernel but, it required me to dig into some very obscure issues caused by some changes in llvm and their linker.

Basically the introduction of large sections in #llvm broke the grub image, and caused more problems to my kernel.

I posted all the details of my debug process in my free #kofi post here: https://ko-fi.com/post/Finally-Dreamos64-is-officially-running-an-ELF-Exe-B0B41AYZW0

Today a new version of the printed version of "Osdev Notes" has been released! :)

The printed version is available here:

Major update is the replacement of the "Stivale 2" protocol with the "Limine Protocol".

The project as usual is on github:

🖥️ #Fiwix is an operating system written from scratch, based on the #UNIX architecture and fully focused on being #POSIX compatible. It's a #hobbyOS and, since it serves also for educational purposes, the #kernel code is kept as simple as possible for the benefit of students and OS enthusiasts.

ℹ️ It follows the #SystemV Application Binary Interface (ABI) and it also aims for #Linux 2.0 system call compatibility

📅 Version 3.4 was released on November 15th: https://www.fiwix.org/news.html

Habemus ELFs! Not the fantasy creatures. But just a set of organized bit and bytes.
I managed to make my #kernel #dreamos64 launch its first ELF executable, although is just printing a message.
ELF support is still very limited, but, is still a great achievement for my toy project.

After more than two months another Dreamos64 update. Not new features but fixes and improvements, full story on #ko-fi
https://ko-fi.com/post/Dreamos64-Status-update-U6U71340LC (free).
I found a nasty bug in a core memory function, where i was returning true instead of false and viceversa. Also some code refactor and documentation improvements.

Habemus #scrolling (nearly) :)

I'm working on adding framebuffer scrolling in #Dreamos64
Initially it will be just scrolling the text up, when it reach the last line.
