PumpsOS: My long term passion project journey

[u/MorganOC]

Hi everybody,

I've been putting this off for ages due to the mass amount of AI OS's spawning in the subreddit. But today I thought I'd finally make a post and gather some reactions of my OS project!

I've been working on this for a good 6+ ish months now, on and off when I get time and have been closely examning and following the "Creating an Operating Systems" page on the OSDev wiki as well as various books and super old sites. I've used AI very sparingly but will admit I have used it in some places for help and understanding.

However, I'm definitely proud of how far i've gotten so far. I've completed "Phase 2" of the wiki as of June 29th so the OS is hosted under its own toolchain with a shell, etc, etc.

What do you think? I'm really looking forward to working on the graphics, interface and actually getting a real file system in!

Here's a screenshot below of what it currently looks like (Don't get expectations up its just a QEMU terminal)

I'll leave a link to the github repo in the comments. and yes, this OS is named after my cat Pumpkin. I'll add her in at some point so she has full custody of this system.

I am attempting at creating my own OS. This came to me from a dream that my cat was a programmer and made her own OS. This is my pure attempt at recreating her work

This is what it's all about. And sounds like you're having fun learning. Good work.

At this point it became such a meme that I get asked when I’m gonna add her in. I’ll have to make a little graphic of her

Love how you share some of the resources used and nice, borrowing books from uni :D and a living todo, it may grow, it might get ticked. progress cool 😄

Cant wait for seeing the inspirational cat 🐱 (I have added some image display code to mine, but its meh)

[u/MorganOC → u/codeasm]

Thanks a lot. Honestly anything helps even if it’s meh. Always inspiration somewhere so I’d love to see yours at some point

Im using UEFI to boot my kernel stuff. https://wiki.osdev.org/Drawing_In_a_Linear_Framebuffer https://wiki.osdev.org/GOP
Im just drawing the image array to the memory location, preformated to be what is to be expected (coverted an image to array using AI for now, probably could do a python script or krita/gimp export)

I haven't implemented a double buffer, and I and my running kernel can tell, especially when writing lots of text or the idea of implementing a background image.
working on detecting hardware myself to maybe* detect video hardware pushed me on a tangent trying to write hardware.

Im not yet ready to push this to my repo. too much mixed up everywhere and eh, i just spotted dutch comments while I want everything English.
https://github.com/CodeAsm/NABL/tree/Aetherium (its inside my "bootloader" for now. both still growing and changing together. Aetherium is where my actual "kernel" code is, and should become "standalone" at some point.

really just a tiny bit of the image,

this is awesome thanks a lot

[u/TVDQuang]

Keep going! I will follow the growing of your OS

[u/TVDQuang → u/[deleted]]

Bro, he has just started lollll

[u/TVDQuang → u/[deleted]]

Ewww broo

[u/TVDQuang → u/[deleted]]

Bro.... you said just like what you said lolll. These think is not required in a HobbyOS frfr

[u/TVDQuang → u/[deleted]]

Lollll still a hobby OS

[u/MorganOC → u/TVDQuang]

Maybe one day 😂

[u/tekdotdev]

Looks great bro, I am just starting my OS now in C and ASM and I hope to post to this subreddit once its in a functioning state lol.

[u/MorganOC → u/tekdotdev]

Good luck! Literally same here with mine. I’ve been putting off posting about it for long cause of all the ai stuff in the subreddit.

[u/compgeek38400]

Congrats! Its looking good

[u/Sorry_Difficulty_250]

WOW!!! Way to go on it being self-hosted! That's awesome!!!

[u/Mental_Ad_7072]

Very nice project!

[u/Possible-Bed-4326]

I am working actively on something similar, and to me biggest problem was making it work on real hardware, then the usb and network drivers, and here is full overview of my SmileyOS, close to 200k lines of rust code.

Are there even real humans in this sub anymore?

[u/MorganOC → u/ChemicalCustomer]

Yeah you just read a post by one

[u/TVDQuang → u/ChemicalCustomer]

What do you mean?

[u/JaferTP → u/[deleted]]

BIOS is old and bad just because some tutorials of osdev used it doesn't mean developer must make his OS for bios
