Here is my side project, 'Hojuix', a 64bit OSDev project. It took me a year to get this far, but it can finally run an ELF file built from C, on a FAT16 filesystem, in usermode. (it page faults because I dont have an exit syscall yet). Next up: XV6's shell (maybe) #OSDev

I spent a good chunk of the past 2 weeks improving userspace memory allocation in MOROS to the point that I can now run my lunisolar calendar program that does a lot of astronomical computations without crashing! #rust #rustlang #osdev #buildinpublic

Yesterday I worked on MOROS random number generator (RNG) and I discovered a bug in the VGA driver by reading `/dev/random` on multiple computers. I've been interested in fuzzing my OS for a long time, and I guess that's what I started doing! #osdev #fuzzing
