What does your OS look like? (Screen Shots..)

[Love4Boobies]

That's why Jay Leno and Jerry Seinfeld are entertainers and not programmers. I'm kidding---I started out describing how this engineering business makes sense for me, I'm sure others may have different opinions. Not to mention that I have always been more interested in computer science rather than engineering (i.e., self.theory > self.practice).

Forgot to put a semicolon in header file :


Tried getting character from console memory(background color doesn't matter):

After much futzing with my hard disk and video drivers, I finally have my complete system, GUI and all, running on a real piece of hardware. Prior to this, I had ramdisks booting with small subsets of the system, and one time I booted the full GUI on my desktop when it was in development - which was completely useless because none of my desktop's input devices are PS/2 and I don't have a USB stack yet.

The compositor is a bit slow, but not unusably so, and it doesn't degrade noticably when new windows are opened. Entire system performance needs tweaks, though, but that's a different story.

I recognize something in that picture!

Yes! I do to, I used to have an intel atom n270! Nice little CPU, but I'm sure that's not what you were re-fering to

Intel Atom processors are terrible.

I was referring to a small program I wrote a few years back, it seems klange has included it with ToAruOS.

yes, sorry, I don't know how it came here, my fault. Anyway, klange, your os looks really great .

Here's mine, with it's funky title bar and status bar in text mode

A few top lines are missing, they are warnings and version info, along with copyright
They got scrolled off

Here is my "rewritten from scratch" project. There is absolutely nothing special here. Except publicly viewable source code that is available on my website. I have to freeze development until I find most of the bugs. Building this simple toolchain + bootloader took surprisingly long.

Hey guys, I've been gone for a while (went off to school this year), but I've been to work on my little kernel over Christmas break!

I've gotten newlib ported and am in the process of implementing all the system calls needed (I've got most done now, just a few left). I've got a (very) basic remote shell written (through serial) and a I've written the ls and echo commands.

I'm extremely excited that it is somewhat functional now! I believe ecstatic is an appropriate word. Here's a picture of me trying out my echo application.

first try on real HW, aparently all went well except that the computer have no ps2 port, so no mouse or kb after boot >.>
os look to run ok since the time change but i belive its now the time to make a usb driver to be able to test more stuff.

Future boot screen (my 640x480x4bpp driver is wayyyy to slow for this as the boot screen right now, it takes 1.5 seconds to load in qemu, and about 3-5 seconds (depending on computer) on actual hardware) (And don't mind all the random stuff, a friend made it for me...):
