Please, add my OS too.

Name: BareNumbersOS

Description: BareNumbersOS is a 64-bit operating system, monotasking with multicore support.
It is a hobbystic project for educational purpose and personal use (especially number crunching).
It is written entirely in assembly language, so it is small, fast and simple.
The OS can use up to 256 cores and 256 GiB of RAM (64 GiB ready) and there is full support for VESA graphic modes.

Thank you.

Just got multitasking working, so now I can add my hobby kernel (OS) to THE LIST.

Hi arseniuss,

I had a look at your website and it said "Free for non-commercial use under GNU GPL v3+ && GNU LGPL v3+". This doesn't make sense, as the GPL explicitly requires allowing commercial use. This is a feature. Otherwise, you'll need to pick another license (or modify the GPL (allowed, if preamble is removed and name changed), but I don't recommend it). You may wish to read some FSF materials to get the spirit of the GPL and see whether you want it or whether you really want something else, it's important not to be ignorant of licensing issues.

Your OS looks interesting, though.

Sounds like you're after the CC-BY-SA-NC instead?

Read some forum posts about licensing and decided to apply GNU GPLv3 despite allowing commercial use. However "Liberty or Death" philosophy is useful.

So ...

Hello to everybody !

Here is new OS. The name is jEmbryoS. It means Java Embryo System (in the sense it is not mature).

It is a bit different - 100% of it's code is Java, from bootloader and up to the sky. The goal is ambitious, but for now it is just alpha release.

The system works in 32-bit protected mode, flat memory model, multitasking, multithreading, single processor, the devices used are the ps2 keyboard and text screen. It boots from flash disk and can run Java applications. Other applications are not supported by design.

Another point - it shows a way to write OS in any imaginable language if it is able to write bytes to the disk.

Hello there!

Please add my project to list

Already added my project to the list, but posting it here for OCD purposes...

Name: OZone
URL: http://ozone.codeplex.com

Description:

OZone is a suite of projects targeted at various platforms, all using the same XML based programming language. This is accomplished by enumerating any platform specific values or constants in an XML document, and using that document to generate the schema and transform documents needed to convert any references to those elements into their underlying value. The project includes platform definitions for Intel, AMD, IBM, Microsoft, .NET, Java, Nintendo, Raspberry Pi, Commodore, Atari and more.

First off, let me say how awesome this site is! I've never seen such a complete helpful library of articles for those trying to roll their own OS. Heck, I never even knew making your own OS was a "thing" lol

That said, I too have already added my project to the list.

Mine is Exelyx, a shell-type GUI / application environment which aims to breathe new life into an older PC by bestowing a bevy of modern OS features upon it without weighing it down with uncommonly needed options and fluff.

It has existed since 1995 in one form or another and has pretty much been "that old OS thingy I used to play with" until the last several months, when I sat down and started giving it some serious consideration. The project has almost bit the dust several times, but I can't seem to ever quite close the door on it entirely.

There's not much to see so far, but sometime soon I hope to have basic application running functionality in place. The only obstacles to that now are 1) my LBA direct disk access routines aren't fully finished, 2) the archive / file management subsystem isn't in place yet and 3) there are a bunch of little bugs that need squashed and tweaks that need made.

What is working correctly so far is: high-res LFB-based VESA graphics with automatic screen mode selection based on resolution and bit depth, a VESA-based system font, string formatting and printing, graphics, animation, pixmap support, basic hardware detection and initialization, minor APM support, CPUID probing and the beginning of PCI bus probing and device detection.

The code is open source so if anyone wants, they can test it out on that old 486 they've been using as a doorstop for the last 15 years I'd welcome the bug reports from anyone doing so.

Speaking of bugs, there is a rather major known one where the OS boots flawlessly in VirtualBox but hangs on my Compaq Mini's real hardware even though both are running FreeDOS.

That's all for now! I'll announce any major milestones here in the future.

I've decided to change the name of my OS to be different from the language I am developing for it. The language will remain Thelema, the assembler will be Assiah, while the OS, in typically humble fashion, shall be named Kether. It seemed to fit the overall theme I've built up (OK, so 'Buggery' for the debugger/disassembler tools doesn't quite fit, but it was the best I could come up with).

Follows the entry for my project:

I'm very new to this OS hobby thing. This is my first OS ever so i will see how it turns out
