What “osdev” means
WikipediaThe development of a hobbyist operating system is one of the more involved and technical options for a computer hobbyist. The definition of a hobby operating system can sometimes be vague. It can be from the developer's view, where the developers do it just for fun or learning; it can also be seen from the user's view, where the users are only using it as a novelty; or it can be defined as an operating system which doesn't have a very big user base.
