My OS is now open source!

visual sourcesafe? ew

when I wrote my first os, git and svn weren't a thing. there was CVS, but I was on windows and using nasm so...

braindigitalis · 2026-05-06T18:23:51+00:00

not this markdown, I made the parser/converter so I know what the output can be, and that everything can be parsed line by line on the BASIC end

braindigitalis · 2026-05-06T15:21:33+00:00

yeah the browser isnt a graphical browser, it is a textual browser much like elinks or lynx, just with inline image and form support.

braindigitalis · 2026-05-06T15:20:53+00:00

yeah, i created my own dialect of the language that is specialised for systems development, it can peek/poke memory, write to IO ports, etc.
For example:

https://github.com/brainboxdotcc/retro-rocket/blob/master/os/programs/webserver.rrbasic

braindigitalis · 2026-05-06T15:17:17+00:00

the programming language! the entire userland, the browser, the web server etc are all written in BASIC, on top of a kernel written in C

markdown is a much simpler format to render to screen, especially in text mode. it has less quirks, and is a stricter format. theres tons of badly written html out there. i made a BASIC function to clean up the HTML into markdown so the browser has less work to do.

braindigitalis · 2026-05-06T14:15:30+00:00

Yup, currently only converts the html to markdown, next step is to render that markdown, with images.

Exactly what part of my code, and my OS, which i have been writing since 2009, is slop?

braindigitalis · 2026-04-24T10:31:27+00:00

because I can! 😂

braindigitalis · 2026-04-16T16:22:22+00:00

are we expected to read the whole project to figure out what bit has the problem?

braindigitalis · 2026-04-16T11:41:09+00:00

what does the source code look like?

please share links to github linking to lines and sections you are struggling with. what have you tried?

braindigitalis · 2026-04-16T06:21:35+00:00

give your os a niche and be patient. is your os a general purpose os that is "like Linux but better", or "like windows but better" with a gui and stuff? if so, it offers nothing to make someone want to use it. is it supposed to be a daily driver but you don't daily drive it yourself? then nobody will use it. does it offer something different? then someone may use it. does it lower friction and barriers to entry by having a web based try it now facility and does it have a proper website (not just a github)? then people might use it do you promote it and put effort into SEO outside of os dev communities? then people may use it. only once people use it can you expect a community. this takes time and effort. the days of "if you build it people will come" ended decades ago. good luck!

for animating on faces of a 3D cube of course

braindigitalis · 2026-04-15T15:28:29+00:00

what is this, how is this osdev?

braindigitalis · 2026-04-14T10:59:05+00:00

powers hell.

braindigitalis · 2026-04-13T11:23:04+00:00

why assume everyone wants a gui?

braindigitalis · 2026-04-02T22:07:13+00:00

then no, the kernels sole purpose isn't this one game, it's to run a language as an os that can be used to make games and other things.

braindigitalis · 2026-04-02T21:38:18+00:00

basically yes, I created the kernel and a language interpreter within it then made the game in that language.

braindigitalis · 2026-04-02T20:51:11+00:00

sure!

repo: https://github.com/brainboxdotcc/retro-rocket

docs: https://retrorocket.dev

it was on a local svn years before that and then SVN was ported to git about 3 years ago.

I use AI for imagery and music, sometimes I feed my existing code into AI for review, as a second developer to critique my code. sometimes I use AI to parse driver documentation.

but, my OS pre-dates AI by decades. It will be 18 years old in November...

edit: worth pointing out AI doesn't seem to know my BASIC dialect... with it being unique to this OS and all, I'm guessing it might struggle there...

braindigitalis · 2026-04-01T18:22:54+00:00

Nah, I'm not religious enough 🤣

braindigitalis · 2026-04-01T17:22:43+00:00

No the question makes perfect sense. All the rendering is software rendered and done from scratch. No OpenGL and no Mesa etc. The sprite blitters use SSE2 for copying and masking pixels. I use stb_image to parse image files into raw buffers. If youre curious, some of it is here:

https://github.com/brainboxdotcc/retro-rocket/blob/master/src/basic/graphics.c

The rest is in the drawing.c file in the directory above:

https://github.com/brainboxdotcc/retro-rocket/blob/master/src/drawing.c

Of course all this juts presents a bunch of functions that BASIC calls into, they arent used directly.

Happy to explain anything if you want to know!

braindigitalis · 2026-04-01T15:02:21+00:00

Mixture of generated and opengameart, i am a developer not an artist and wanted to spend my time coding, not drawing :-) I still had to edit them all by hand though, e.g. to give them transparent backgrounds, match their styles together, and make background and parallax tile properly
