GNU and Linux

• GNU
• 1) Covers Utilities
• 2) compilers, tools, debuggers, and editors
• 3) Ex GNU Compiler Collection (gcc)?

• Linux Kernel
• 1) multitasking
• 2) shared executables
• 3) demand paging
• 4) swap
• 5) dynamically shared libraries
• 6) file system support

Here is how GNU and Linux fell in love.
Hi. I am Richard Stallman and this is my GNU
Project I started in 1983. Last thing to finish
is the kernel that I started in 1990.
Hi I am Linus Torvalds and my project is the
Linux Kernel and it is 1991 and I finished.
Is that what you are sitting on? Lets put our
projects together. But I see you did not publish
under the GNU GPL.
No I did not but I will. And then you can cut
into the Linux Kernel.
Good you do that and I will do my thing and will
support open source.
Aaaahhh. That feels good to combine. I will
continue writing and revising the GNU GPL so free
software with reign.

GNU GPL

• With free software, the users are in control.
  Most of the time, users want interoperability,
  and when the software is free, they get what they
  want. With non-free software, the developer
  controls the users. The developer permits
  interoperability when that suits the developer
  what the users want is beside the point. -
  Richard Stallman

Goals of GNU GPL

• the freedom to use the software for any purpose,
• the freedom to share the software with your
  friends and neighbors,
• the freedom to change the software to suit your
  needs, and
• the freedom to share the changes you make.

Where is GNU/Linux now?
1) Where isn't GNU/Linux now?

• Servers
• Supercomputers
• PC's(including Mac's)?
• Embedded Devices
• Xbox

2) One Laptop Per Child?

Where is Windows?
This is Vista's Kernel Map
12
What Microsoft Does

• Microsoft believes it is so powerful that it can
  design an incompatible format, create obstacles
  to its implementation by others, and pressure
  most users to switch to it. Do you think users
  are really as foolish as Microsoft predicts? -
  Richard Stallman

Myths about Linux
Plug and Play- is not a windows level
Kernel needs stable API so vendors will write
drivers
You can't get your driver into the kernel
Linux has no obvious design

4 things that the GNU GPL wants to protect.
