Make friends with Linux

This blog was originally just talking about the tricks and software in Windows environment. From now onwards (hopefully), Linux will be posting additional material to me. Let's get acquainted with linux.

A Short History Linux
What is Linux? Linux is a kernel created by Linus Torvalds. So what's the story until Linus created the kernel of this.

Linus Benedict Torvalds, born in Helsinki, Finland on 26 December 1969. Linus entered the University of Helsinki Department of Computer Science. Linus gets a lesson on the campus of Unix and C Programming, Linus bought his first PC. In his time Unix operating system which is very famous and very attractive interest. Unfortunately this is very expensive operating systems and source code is freely available. Then as an alternative, Linus tries MINIX operating system (UNIX Minimal) which is a simple clone of the UNIX operating system.

MINIX was created by Dr. Andrew Tanembaum to teach students about the internal workings of the operating system. But Dr. Andrew Tanembaum has no intention to develop a MINIX. MINIX source code is provided in the book of their own and the floppy disk that can be purchased and of course has the distribution rights.

Because the MINIX source code that is not free in the person who tinkers, make Linus thinking to create an operating system similar to MINIX, but do not have limitations for development or copyright which means it is free. Linus finally managed to make a kernel (core operating system) that can be used but still have very limited capabilities.

After that Linus send emails expecting cooperation programming community. Message from Linus provides exceptional response. Great programmers develop hand in hand-made operating system kernel to be an operating system that is ready for use.
Even until now programmers from various communities go hand in hand to develop this operating system, so do not be surprised if up to now circulate a lot of Linux distros. Some are free and some are paid.

For the next post about Linux distributions are known.
