Wow! Just saw LinuXpert's review of DEKUVE! So grateful for your time and insightful feedback. Made my day!

FreeDOS: History, Legacy, and a Valuable Resource for Old Machines https://lobste.rs/s/apmwct #historical #osdev #retrocomputing

Anyone got an idea how I can access kernelspace of reality? I'm experimenting with the manipulation of user objects, like translation a human object into a dragon one. But some stupid security rules don't allow a user program to modify other processes. Is there a module system? How can I get the code into kernelspace?

Super excited to present my OS research at #wasmio25 in just 2 days!

For two years I’ve been working on a massively concurrent, highly reliable operating system ( using #wasm written from scratch in #rust ) for the 21st century!

stop by it will be great!

This is a surprisingly interesting blog post. From the title, you might expect it's just a rant or complaint. But it goes into a really interesting discussion about how to get multiple libc implementations to cooperate, how an OS can break apart libc into more modular components like a libsyscall.

Listening to #Lagtrain while trying to make #ToaruOS work on my Toshiba #Chromebook 2 again after one year (because klange hadn't fixed the /bin/init load failure bug at the time and I thought it was just a Chromebook issue).

Released full sources of my 32-bit #arm #forth dialect : https://github.com/grz0zrg/GnosTh

And a series of write-ups...

Das #uboot API at ARM level :

Forth dialect ARM implementation :

Most useful for #baremetal / #osdev enthusiasts might be the U-Boot guide as it can be used for all U-Boot supported boards.

Also wrote a Forth introduction in #javascript earlier on :

Feel free to report any errors or usage issues.

I got back to working on #HighlightOS , a x86_64 OS (kernel) made from scratch using #assembly & #Rust.

If you're interested in the project, you can go check it out on GitHub:
https://github.com/adamperkowski/highlightos

I'm currently working on implementing everything into Rust: https://github.com/adamperkowski/highlightos/pull/6

Everyone is more than welcome to contribute!

I have never seen any pull requests to Anatolix since moment I created repo for it. Please, contribute. Repo link: https://codeberg.org/GNUAn/Anatolix

#osdev but it's flow-based programming.

did more #OSDev work on the kernel today. changed the linker script to set proper locations for the stack and paged memory, and displaying a bunch of system info to check everything is set up correctly. and also added a little logo while i was at it cause why not >_>

my little OS kernel advances ever so slowly
#OSDev #RiscV

eyyy, babby's first kernel!
#OSDev #RiscV

i still cant work out what i wanna do with my #OSDev project. i feel like i should try and figure out QEmu so that my efforts are the most "real", but that thing feels like such a black hole in terms of documentation

on the other hand building my own #riscv VM seems easy and i wouldn't have to use QEmu, because implementing RV32I opcodes is easy, but then you get into the status and control registers and now things are all super complicated again

i have been here for nearly a year and i never made a #introduction post?

Cheers! I’m a #cpp developer with a background in network engineering, i organize #neurofunk #dnb events and i’m active in #austrian #leftist #politics at Junge Linke.

My Blog has been a bit stale lately but i plan to push more technical, political or philosophical posts to it.

I’m mostly interested in #osdev, #infosec, #cpp, #politics, #netzpolitik and of course #shitposts.

I first joined the Fediverse somewhen in 2019 but started using it actively in early 2022 over at cybre.space (RIP). Nowadays i run my own cozy instance larkspur.one.

Hi everyone, this is my #introduction !

I am a CS student, with my interests ranging from high level stuff (#ai, #webdev) to low level stuff (#osdev, #embedded, #linux). I also like electronics and I love repairing things! #math and #science were once my favorite subjects, and I still read about them when I have the time.

I also have a loose relationship with art: I love #cinema, and sometimes when I'm bored I might draw or write music.

I also love #nature - I would never say no to a hike!

OSDev Weekend Project - Decided to build out a custom init system / window manager / UI toolkit on top of a Linux kernel. All in Rust, all using musl libc.

I quite like this approach.
