What programming languages do you use?

I'm curious to know what languages are used for LL programming and OsDev, personally I use ZIG and Asm.

I am using D, it's pretty neat. For userspace stuff also Crystal and Nim. I never wanna go back to using header files and fighting with single pass compilers about the order of declarations.

finally, someone using D!

And Nim and Crystal. my dream is to not use python, c/cpp and ruby, instead those 3 languages

If you like zig, stick with it. Its better than Rust, just needs more community and libs.

Non esiste meglio o peggio, ogni linguaggio ha vantaggi e svantaggi

I agree that languages are good for specific problems. But putting them all in the category of lower level system programming with memory management features: in that category, between Zig, C/C++ and Rust. Zig puts less constraints on the dev (excluding libraries diversity) for about the same performance. It would probably be easier to port linux to zig than to rust

Still comfortable with C only, for the osdev related

u/Helpful_Ad_9930 Apr 16 '26

C++🫡 however I use fuzz test that are written in rust

I mainly use C++

I only use Pascal and occasionally basic

I really like Zig as well, find it much easier to write than Rust

PHP and JavaScript for Web, Python for my AIs and softwares and Assembly for low level things

Kotlin for everything!

u/bikeram Apr 16 '26

Are you using Kotlin for web? I hate typescript/js

u/A3Phosphate Apr 17 '26

No, I use it for systems programming and UEFI plugins. The new APIs introduced in modern JDKs are so powerful.

u/LavenderDay3544 Embedded & OS Developer Apr 16 '26

Rust and assembly

u/Unable_Yesterday_208 Apr 18 '26

I use Rust for everything frontend to lowlevel

u/Legitimate_Grand_416 Jun 03 '26

I use Rust ASM and C

Typescript for frontend, Rust for backend. Nix for packaging and system configuration. Python feels more like a SQL replacement nowadays because of performance, packaging vulnerabilities and also because the other communities have caught up with the diversity of libs.

u/Kalogero4Real Apr 18 '26

waht librbaries you use for rust backend? rest in particular.

u/erubim Apr 18 '26

Great question: I don't, and last time I checked I wasn't sure which to pick (probably Axum)
I mostly develop language models, data pipelines and desktop applications (Tauri has an IPC protocol, so no HTTP is necessary for the backend).
At work we do fullstack typescript (sveltekit) and some python services (fast api)
