While #RustLang’s Memory Safety is a strong foundation, its true power lies in Type System & Ownership Rules.

In this #InfoQ article, Andy Brinkmeyer dives into what makes Rust special beyond Memory Safety - how it helps developers avoid common mistakes and write code that’s inherently more failure-proof.

Hi Fediverse
I was wondering if there is anyone who can give some advice for learning system development (linux kernel development to be specific) for a web dev guy like me

I know I can google it or ask an LLM about that, but real-life advices from you guys will be very appreciated 🙂

Is there anyone who have walked that path? 👀

#GoLang channels are more than message queues: they are the core synchronization tool in concurrent Go programs.

Learn how happens-before semantics affect memory visibility, prevent race conditions, and enable predictable high-concurrency systems.

Habemus ELFs! Not the fantasy creatures. But just a set of organized bit and bytes.
I managed to make my #kernel #dreamos64 launch its first ELF executable, although is just printing a message.
ELF support is still very limited, but, is still a great achievement for my toy project.

After more than two months another Dreamos64 update. Not new features but fixes and improvements, full story on #ko-fi
https://ko-fi.com/post/Dreamos64-Status-update-U6U71340LC (free).
I found a nasty bug in a core memory function, where i was returning true instead of false and viceversa. Also some code refactor and documentation improvements.

Initially it will be just scrolling the text up, when it reach the last line.

I saw a chart about wages in programming languages

When it comes to "system programming " languages, it turns out Zig is gonna be rewarded more than Rust

But I never read about Zig on the fediverse, I only run into Rust

Why is that ?

So ATM, I'm in the middle of writing a reader writer spinlock. My question is why a standard one doesn't exist?

For example, pthreads have spin lock, and a full reader writer lock. Is this niche, or is there a fundamental reason this is a bad idea?
