Bootstrap yourself to write an OS from scratch
bit sad in the era of 64 bit computing still every resource is at most about protected mode. osdev wiki has some info about long mode, but it&#x27;s all fragmented. Been working now for ages to try to decipher amd and intel manuals about that :&#x27;). Still ,nice this page, always good to inspire people to write their own system softwares because i think it&#x27;s to much &#x27;magic&#x27; still where as it&#x27;s doable even for 1 person to write an OS that is dedicated to for example a single task runnign in user mode. writing a multi-user &#x2F; multi-purpose OS is maybe more work, but in those OSs a lot of problems exist today which is causing a need for people (imho) to step back and look at if this is really the way we want to go with computing... i don&#x27;t see why a webserver or something with a single purpose like that needs to be on a multi-purpose OS. It just increases complexity and overhead and people have a world of trouble configuring an OS to do just 1 task good, have to stip our 90% of what comes with a basic install to reduce attack surface and get resource usage under control. I hope we will see more dedicated purpose OSes come up which handle 64 bit, and perhaps someday some resources for programming specifically that. I&#x27;m thinking of sharing some of my knowledge on the area sometime, but i dont know how much interest there is and seeing as i&#x27;m a bad writer and still pretty shit coder it will probarbly take me too much time now compared to how much use it would be (if i do it, compared to some veteran in the field!).
