OSDev.org

I even added a game of life simulator!

This looks like a osdev Picasso. How do you play?

A few screenshots. This interface is just to test hardware interfaces. It will change.

Here's some shots of an operating system I'm working on called TachyonOS.
It uses a text-mode menu based system but has good graphics API as well.

@Prochamber: Your latest "The central application menu." screenshot is excellent! I do not know why but it looks very professional. Very polished and easy to use.

Agreed, it's quite an improvement on MikeOS's simple file browser dialog as an application menu.

@Prochamber: Does the central application menu read app names from the apps themselves or are they hardcoded in?

I think a simple, easy to use interface is very important to any operating system. It's the first thing the
user sees and it makes an important first impression.

Every time I see the horrible colour combinations of MikeOS I die a little inside...

Seriously though, it's good that MikeOS has so many great user interface components.
The first thing I did when I ported MikeOS was create a new interface, I wanted it to look more like
the start menu you see in GNOME or KDE, with application names rather than file names and
have submenus and mix system commands with programs. I spend a long time figuring
out the right colour combination.

One of my favorite things about the interface is that you can make custom background through the
picture editor.

Actually, it's a hard coded list at the moment. However it would be fairly easy to make it run off a file. I could add this to build #6 that I'm
currently working on.

I have a google code at: https://code.google.com/p/tachyon-os/

It's not a terrible lot compared to some of the OSes on here, but here's BlacklightEVO.



The graphical mode is set through VirtualBox's display adapter interface the same way as the official VirtualBox Guest Additions drivers set it.

I'm incredibly tired, and incredibly pleased with it.

Slowly, but surely, getting Vim running:

Oh, yeah. I ported Quake to my OS. Since a video is more powerful than mere screenshots, here's a video of it in action:

Here is mine - TeraOS.
I have blanked out my real name, as I am only 14.
The first is build 5, and the next is build 50.
Build 5 was extremley poor, no CLI working.

Build 10 had CLI functionality.
Build 25 ran on real PCs (fxrstor thing in IRQ handler causing fault).
Build 52ish introduced program loading.

Current build: 65.
The logo in graphics mode is copyright me, by the way.

The OS is written in C++, and uses polymorphism.

With a few hacks here and there, Vim, in full 256-color theme and syntax-hilighting goodness:



It has been a productive morning.

With a bit of effort hacking around their terrible build system (at least for cross-compiling purposes and because their ./configure works in non-standard ways, that their assembly is written in yasm..., and they do a few bad things), I managed to port libav to my operating system. I hacked together a quick and dirty video playing using libavcodec, libavformat and libswscale and the result is that I can now play videos under my operating system! It even runs smoothly under virtualbox, besides the occasional crash:

Here is my OS as it currently stands.

I need to find time to get back into it.

Multitasking Acorn MOS imitation which has FAT32 and ISO9660 support (with long filename support). Loadable kernel modules, commandline with programs.
Filesystem access available to those programs.

That looks very nice, brain. I like the use of just three simple colours - black, grey and yellow.

I'll join the fun.

My OS has no name (yet) but it works.
Nothing fancy, it has multitasking, paging and usermode support.
It also has a simple implementation of printf() and some pipe support I've been working on for my keyboard.

Pipe, kopen and kprintf tests:


Simple built-in kernel commandline with built-in ls and cat support:


Still working on multiple task/process support and ELF loading routines but even with my limited amount of time it's getting somewhere.
