Lesson 01 : Linux History

In this lesson , we will learn about Linux history and open source software.In 1991 in Helsinki University, Finland Linux was born by Linus Torvalds where he began developing a UNIX-like kernel.He first announced his work in a now-famous e-mail message on the comp.os.minix mailing list :

From: torvalds@klaava.Helsinki.FI (Linus Benedict Torvalds)
Newsgroups: comp.os.minix
Subject: What would you like to see most in minix?
Summary: small poll for my new operating system
Date: 25 Aug 91 20:57:08 GMT

Organization: University of Helsinki

Hello everybody out there using minix -
I'm doing a (free) operating system (just a hobby, won't be big and
professional like gnu) for 386(486) AT clones. This has been brewing
since april, and is starting to get ready. I'd like any feedback on
things people like/dislike in minix, as my OS resembles it somewhat
(same physical layout of the file-system (due to practical reasons)
among other things).
I've currently ported bash(1.08) and gcc(1.40), and things seem to work.
This implies that I'll get something practical within a few months, and
I'd like to know what features most people would want. Any suggestions
are welcome, but I won't promise I'll implement them :-)
Linus (
PS. Yes - it's free of any minix code, and it has a multi-threaded fs.
It is NOT protable (uses 386 task switching etc), and it probably never
will support anything other than AT-harddisks, as that's all I have :-(.

Kernel is the core of the Linux operating system and it is layer between the software and the hardware that manages and controls resources such as processor and memory.

Despite of the humbleness of the email, Torvald’s kernel was to become a professional kernel held in the highest regard in the computing world. Today, Torvald’s kernel, along with tools from the GNU project and elements from other open source projects (X from Xorg, for example), make up the core of Red Hat Enterprise Linux and other Linux distributions, such as the Fedora Project.
