Warum als portable inflate Implementation hast du einen kleinen Fehler, der nur bei manchen Bilddateien auslöst. Könnte auch daran liegen, wie ich die Daten buffere oder ins Dateisystem streame.

Programming is fun they said 😐

making my own file system was fun.... the designing part that is... i didnt get much done, because i spent 6 HOURS because a single bit was a 0 instead of a 1...

Also, one of many UI sketches (a UI for the OS is far off, but I'd like to be ready when the time comes).

This is an interface window showing an Embed item with an invalid path inside.

I'm currently reading "Building a Debugger" by @tartanllama.xyz. This book is just *awesome*! Now, I'm trying to reimplement everything in Rust - to get even a better understanding how Debuggers are working internally :-) #rust #rustlang #debugger #osdev #x64
