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.

UA: Здоров мастадонці! Я роздумував про зміну стеку і мені цікаво чи може хтось кинути хороший курс по C++ бо я щось не впевнений у тому, що дає гугл
Наперед дякую!

EN: Sup mastadonians! I was thinking about changing the tech stack and I wonder if someone could give me good online course for learning C++ because I'm not sure about what Google throws me
Thanks in advance!

Habemus #scrolling (nearly) :)

I'm working on adding framebuffer scrolling in #Dreamos64
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 ?

Introducing #Lapce: https://bit.ly/3T46WwE

#SystemProgramming Quiz
Given that you only have the range of line and char position of a file changes, how do you modify/update that file without reading it?

Some time ago I saw a talk about the evolution of the C standard with just a bit of neew features added, recently

I'd love to find it again

#C

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?

#CaseStudy - TrueLayer's main business is not #systemprogramming, yet they decided to bet on #Rust. Why? How?
