The Development of Linux is one of the most surprising Events in the UNIX area.
Linux is a new UNIX version derived from work of Linus Torvalds, who wrote the basics of the operating system himself.
His work was picked up by people around the world who, in a remarkable cooperative effort, wrote a complete UNIX system from scratch.
Early versions of Linux were primitive and unstable, but current versions (version 2+) are powerful and efficient. They also have an amazing range of features, mainly because whenever Web users want a new feature, they write it. From the system administrator's point of view, Linux is very much like System V UNIX. It offers the full range of facilities, and the administrative structure is similar to the other commercial UNIX versions. For someone trying to learn UNIX, it has some striking advantages:
Hello everybody out there using minix:
I am doing a (free) operating system (just a hobby, will not be big and professional like gnu) for 386(486) AT clones.
This has been brewing since April, and is starting to get ready. I would like any feedback on things people like/dislike in minix, as my OS resembles it somewhat (same physical layout of the filesystem (due to practical reasons) among other things)
Any suggestions are welcome, but I will not promise I will implement them :-)
Linus (email@example.com) PS. Yes, it is free of any minix code, and it has a multi-threaded fs.

It is NOT protable[sic] (uses 386 task switching etc), and it probably never will support anything other than AT-harddisks, as that is all I have :-(.
Minix was a UNIX-like operating system that ran on PCs in the early 1990s. Like Minix, Linux was also a clone of the UNIX operating system.
To truly appreciate how a free operating system could have been modeled after a proprietary system from
AT&T Bell Laboratories, it helps to understand the culture in which UNIX was created and the chain of events that made the essence of UNIX possible to reproduce freely.
