An Elf Odissey! #dreamos64 I recently added support for basic ELFs in my hobby #kernel but, it required me to dig into some very obscure issues caused by some changes in llvm and their linker.

Basically the introduction of large sections in #llvm broke the grub image, and caused more problems to my kernel.

I posted all the details of my debug process in my free #kofi post here: https://ko-fi.com/post/Finally-Dreamos64-is-officially-running-an-ELF-Exe-B0B41AYZW0

#Linux operating systems are not keeping up with new apps and gooey graphics.

People can't give up time to use the command line to keep modern features working.

Text-based User Interface command line apps and multiplexers to help?

Mac OS has been described as a fancy BSD GUI and MS Windows as a straight-jacket ecosystem. Point and click tropical beaches.

Today a new version of the printed version of "Osdev Notes" has been released! :)

The printed version is available here:

Major update is the replacement of the "Stivale 2" protocol with the "Limine Protocol".

The project as usual is on github:

Question for users of Linux, BSD or other non-Apple-or-Microsoft-OS':

If you where forced to choose between using Windows or Mac OS as your primary OS (and if money was no issue) which one would you choose?

An update to my book "Osdev Notes" has been released.
This update contains as usual lot of typo fixes, but it also expand few areas: The "Syscall Example" chapter and the "Elf" section.

As usual the printed book is available on lulu: https://www.lulu.com/search?sortBy=RELEVANCE&page=1&q=osdev+notes&pageSize=10&adult_audience_rating=00

And the link to the github release is here: https://github.com/dreamportdev/Osdev-Notes/releases/tag/v1.3 As usual the book can be downloaded for free. #osdev #selfpublishing #programming #operatingsystem #kernel #assembly #x86_64 #operating_systems

Should a #Linux #programming college course taught in #C be a mandatory part of a #computerscience degree? Or would it be sufficient to teach the theory of Linux programming while using a higher level language like #rustlang with more usable abstractions?

I feel like #C could be relegated to an #operatingsystems course to really delve into the intricacies of system calls and such.
