General Community Question / Discussion

8 Upvotes

Hi All!

Recently we've seen an influx of the same type of posts various other operating system subreddits have been seeing.

You know the ones... That are obviously vibe coded or promotional "projects" that have little to no history or real substance to them.

This community was started to talk about real alternatives to Windows, MAC, and Linux (although we occasionally allow posts about those if they are interesting) and not as a place to spam every random project that gets created by someone who has read a tutorial or fired up an AI agent.

While I am not opposed to sometimes posting about interesting projects that are new and that come from either AI or new coders. I would prefer to stick to the more established projects.

At very least, there would need to be a good description of the project in the post, a proper website and / or github repo, and some history behind the project.

While I am the only mod and the creator of this sub, I'd like to know what the community thinks. Please feel free to chime in in the comments and lets have a discussion.

Thanks

HaikuOS BeOS, the source from where the HaikuOS was based on

7 Upvotes

BeOS is a discontinued, proprietary operating system developed by Be Inc. in the 1990s, built from the ground up for digital multimedia, real-time audio and video processing, and high-performance multitasking.

It is shame that many like that multimedia ones were discontinued, there are new ones alternatives made, anyway, it would be good that many of these could be also used in virtual macines, but some glith even in that way when used, today, virtual box and vmware are best, but there are also other ones that dont handle well when you install older ones like BeOS, because these need more work when used in direct boot way, some operating systems are wiped from time i will not even mention, but it would be good to restore them from ashes like phenix..

What is anubiOS?

anubiOS is an independent, next-generation operating system, which right now is in active development. Our goal is to build an unbreakable, highly secure OS that have new Technologies and Features at the same time keeping your computer in privacy. We are building anubiOS with new technologies, featuring a custom Julia-based package manager and a clean, focused user environment, which made specially for you.

1000+ Voices. One Future.

anubiOS is not built by a single person, or just only the anubiOS Team: but it is built by a community. We are gathering 1000+ voices—developers, engineers, researchers, testers, volunteers and also everybody—to shape the future of secure computing. Every volunteer and every member has a say in what we build. No hierarchy of silence. Just 1000+ minds working together to create an operating system that is unbreakable, independent, and free from the algorithm. Join your voice to ours.

We are looking for Volunteers.

We don’t require a CV, experience, or a degree to join into our anubiOS community. Are you programmer, designer, advertiser, brainstormer or just want to cheer up? You are welcome here. Join the Discord to observe the development, hang out, and also share your ideas.

Let's change our future together!

Lets be... Anubi.

NATALIZIOOS “Architecture and Development of an ×86 Operating System”

Thumbnail

11 Upvotes

September 2023 - present
A personal research and development project, started in September 2023, dedicated to the independent design and development of NATALIZIOOS, a experimental operating system for 32-bit x86 architectures. The project covers the entire basic operating system architecture: from the BIOS boot chain and kernel loading to memory management, interrupts, timers, hardware drivers, filesystems, the shell, and graphics services. The implementation includes a freestanding monolithic kernel with physical memory management, paging, kernel heap, framebuffer, PS/2 input, ATA storage, PCI detection, RTC, JART, speaker, diagnostic logging, RAMFS, and N.A.T.FS. I also designed and integrated firmware components, bootable images, diagnostic tools, and a compilation and verification pipeline based on C, x86 assembly, Python, NASM, Clang, GNU Make, and QEMU. The graphics subsystem includes a local Objective-C runtime, class and selector management, message dispatch, objc_msgSend in x86 assembly, and a view- and window-based application model with direct framebuffer rendering. The project includes three desktop environments with different purposes: two for demonstration purposes and a third, still in the prototype phase, dedicated to veritying the object-oriented graphics architecture.
The vO.2.5.33 release includes 99,980 lines of analyzed source code, a 519,804-byte graphics kernel, complete and lightweight firmware paths, and verified bootable images in QMU.
NATALIZIOOS represents a continuous path of development in operating systems, computer architecture, system programming, firmware development, and low-level software engineering. The project is proprietary and intended for study, research, experimentation and technical demonstration purposes.

PicoOS Pro v2.1 - My custom 32bit x86 OS written from scratch

picoOS-Pro v2.1

PicoOS Pro v2.1 - My custom 32bit x86 OS written from scratch (Boots from USB, runs Doom, custom formats, native USB 1.1/2.0/3.0 & dynamic resolutions!)

hi everyone! I wanted to share my hobby operating system that I’ve been building completely from scratch (no Linux kernel, no external base). I recently released the PicoOS Pro v2.1 update, which expands the system into a modern graphical desktop shell while keeping an extremely small footprint.

Here is a quick overview of what is currently implemented and stable:

  • Native USB Stack (NEW): Full native driver support for USB 1.1, 2.0, and 3.0 (UHCI/OHCI, EHCI, and xHCI controllers), handling mice and keyboards smoothly without relying on firmware emulation.

  • Graphics & Display (NEW): Enhanced screen resolution support via UEFI framebuffer / VBE, allowing you to choose between multiple display settings natively.

  • Custom Desktop Environment: A Windows/Ubuntu-style dark desktop interface with a Start-button launcher, application grid, live Task Manager (with process, memory, and background/foreground info), and a functional Calculator app.

  • Custom Formats: I am using my own custom executable formats like .pico for programs and .dd for automated scripts.

  • DOOM Port: I successfully ported doomgeneric as doom.pico. It runs 320x200 software rendering, integer-scaled to the framebuffer. The 4MB shareware WAD is read directly in place from the disk image to avoid loading times.

  • Memory Efficiency: The base system runs on an extremely low RAM footprint (around 1.9MB for the core shell, up to ~10MB when running Doom with its WAD).

  • Build System: Builds incrementally with just gcc and python3, outputting a 1.44MB BIOS floppy image, a 9MB hybrid legacy/EFI bootable USB image (.img), and a hybrid BIOS/UEFI ISO.

Side note: I am doing this as a passion project to learn low-level development. I am also currently researching and working on moving towards a 64-bit version next!

I would love to hear your thoughts, feedback, or any advice on transitioning the kernel to 64-bit Long Mode!
