It must be pretty cool to have your OS developed up to a point you can actually develop apps for it.

The GUI is sufficiently complete to allow me to write applications.
Hydrogen OS is an "embedded OS", so many applications will be integrated to the OS binary, even when
it is possible to load from disk. This can be useful.

Cool, its looking very nice

I like this because you only have to load it in to memory once and then the inbeded apps run off of RAM like puppy linux, witch less loading and less wear and tear on the disk

All OS code is located in the conventional memory, and the maximum size of the OS binary is 512 Kbytes (97 KB for the current version).
So there is enough space to add a lot of things.

I've just put the current version of my OS, "Escape", online, so I thought I post it here so that you can see and comment it

@Hydrogen OS:
Looks really cool!
I'm wondering about the display "FPS: 27". Are you redrawing the whole screen as fast as possible? Or how does it work / what does it mean?

Impressive, especially since you're working less than a year on it. Are you trying to be POSIX compliant?

Not really. I don't plan to port user-apps some day, because I want to write them myself. So ATM there is no need for being POSIX-compliant. But perhaps I'll add a compatibility-layer later.

Really nice! Do you have an online repo?

I've joined forces with essial and he's started with the video mode API. So far it only works in qemu but it's a start. (mouse works by the way )

Thanks
No, but you can download the source-code on the mentioned website, too.

I was asking since what I can see from the commands and output etc. it looks awfully like Linux/Unix. Not bad per se, but if you're not going to be POSIX compliant, I'd personally opt for something more "original" (though I'm not saying you should, of course).

Yes, many (but not all) user-apps look like the ones from Linux/Unix. Thats because:
- I don't want to make anything different just to make it different
- Many things in Linux/Unix are not bad and most people are used to them
However, I'm trying to go my own way (and I think, I've done it with some parts), but it should still make sense and be usable. And thats not easy.

True, Unix has about 40 years going for it :).

FINALLY!!!! Self-hosting is so close.. just need to port unzip or something so I can archive up my kernel sources and give them a fresh native compile.

EDIT: This could be mistaken for DOS. Maybe I should add some colors to my shell.

I had colours in DOS! ANSI.SYS FTW!

Very refreshing to see a non-POSIX like CLI though.
