The document discusses the history of free and open source software. It begins with Richard Stallman founding the Free Software Foundation in the 1980s and developing the GNU operating system as an alternative to proprietary Unix. It then covers Linus Torvalds developing the Linux kernel in 1991, allowing GNU to be combined with Linux to create a fully functional free operating system. Finally, it briefly discusses the rise of free software distributions and web browsers, different free software licenses, and additional sources to learn more about the history and development of free and open source software.

● What is „Free Software”?
● How it all started?
● GNU – 100% Free Operating System
– Copyleft - GPL
– Linux
● Free Software in real life
● ...and more

5. Free?
The word "free" in our name does not refer to price; it refers to
freedom. First, the freedom to copy a program and redistribute
it to your neighbors, so that they can use it as well as you.
Second, the freedom to change a program, so that you can
control it instead of it controlling you; for this, the source code
must be made available to you.
Richard Stallman (Free Software Foundation)
February 1986

19. GNU GPL
● Freedom 0: The freedom to run the program, for any purpose
● Freedom 1: The freedom to study how the program works, and
change it so it does your computing as you wish.
● Freedom 2: The freedom to redistribute copies so you can help your
neighbor
● Freedom 3: The freedom to distribute copies of your modified
versions to others. By doing this you can give the whole community
a chance to benefit from your changes.

23. Linux
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 (torvalds@kruuna.helsinki.fi)
PS. Yes – it's free of any minix code, and it has a multi-
threaded fs. It is NOT portable (uses 386 task switching
etc), and it probably never will support anything other
than AT-harddisks, as that's all I have :-(.
