Richard Stallman
Was born in 1953 in New York city
Started writing programs while in high school
Graduated from Harvard earning a BA in Physics in
1974
Became a programmer in MIT Artificial Intelligence
(AI) Laboratory while doing his BA in Harvard
Enrolled as a graduate student in Physics at MIT
Abandoned his pursuit of a doctorate in physics in
favor of programming
His Career in MIT AI Lab
Joined MIT June 1971
Became a regular in the hacker community there
Published a paper on an AI truth maintenance system
(while a graduate student) which was still the most
general and powerful form of intelligent backtracking
as of 2003
Worked on software projects such as Emacs, TECO
and Lisp Machine Operating System
In the early 1980’s the hacker community began to
fragment
Quit his job at MIT in 1984
Copyright and restrictive software
licenses
In 1980, Stallman and other hackers
at AI Lab were refused access to the
source code of the first laser printer,
the Xerox 9700
Stallman had modified the software
on an older printer, so it
electronically messaged a user when
the person's job was printed, and
would message all logged-in users
when the printer was jammed.
Thanks to a few additional lines of
software code, AI Lab employees
could eliminate the 10 or 15 minutes
wasted each week in running back
and forth to check on the printer.
Free speech
vs. Free beer
Not being able to do this to the new printer was a major
inconvenience as the printer was on a different floor
from most of the users.
By the 1980s, almost all software was propriety.
Propriety means that it has owners who forbid and
prevent cooperation by users.
This made the GNU Project necessary.
The ultimate goal is to provide free software to do all of
the jobs computer users want to do—and thus make
proprietary software obsolete.
GNU
(for Gnu’s Not Unix)
The printer access code incident convinced him that people
should have the freedom to modify the software they use.
In September 1983 Stallman announced GNU project on Usenet
newsgroup net.unix-wizards
“Starting this Thanksgiving I am going to write a complete
Unix-compatible software system called GNU (for Gnu's Not
Unix), and give it away free to everyone who can use it.
Contributions of time, money, programs and equipment are
greatly needed.”
"GNU will be able to run Unix programs, but will not be identical
to Unix. … We will make all improvements that are
convenient, based on our experience with other operating
systems."
GNU project
GNU operating system is a complete free
software system, upward-compatible with Unix
You may or may not pay a price to get GNU
software but once you have the software you
have 4 specific freedoms in using it
GNU is compatible with Unix because the overall
design was already proven and portable, and
compatibility makes it easy for Unix users to
switch from Unix to GNU.
Free as in Freedom
(run, copy, distribute, study, change, improve)
The word “free” in “free software” pertains to freedom, not
price.
Freedom 0. The freedom to run the program, for any purpose.
Freedom 1. The freedom to study how the program works, and
adapt it to your needs. (Access to the source code is a
precondition for this.)
Freedom 2. The freedom to redistribute copies so you can help
your neighbor.
Freedom 3. The freedom to improve the program, and release
your improvements to the public, so that the whole community
benefits. (Access to the source code is a precondition for this.)
GNU project
GNU incorporated longer file names, file version
numbers, and a crash-proof file system.
Includes kernel, compilers, editors, text
formatters, mail software, and many other
things.
Linux, a Unix-like kernel, was developed by Linus
Torvalds in 1991
Richard Stallman created a new multi-language,
multiplatform compiler
Kernel in GNU system

Linux is the kernel
the program in the system that allocates the machine's
resources to the other programs that you run.
an essential part of an operating system, but useless by
itself
it can only function in the context of a complete
operating system.
Founded by Rms on 4 October 1985
A tax-exempt charity for free software development
Income: Distribution of Emacs tape and free software and of
other related services (e.g.: CD-ROMs of source code, CD-ROMs
with binaries, manuals)
Income: Funding from members’ dues
The FSF holds copyright on a large proportion of the GNU
operating system, and other free software.
The FSF publishes the GNU General Public License (GNU GPL),
the world's most popular free software license
The FSF campaigns for free software adoption and against
proprietary software
GNU General Public License
The first copyleft license for general use
Grants the recipients of a computer program the rights
of the free software definition and uses copyleft to
ensure the freedoms are preserved, even when the work
is changed or added to
Copying and distributing the license is allowed since the
GPL requires recipients get "a copy of this License along
with the Program"
Copyleft
A play on the word “copyright”
The right to distribute copies and modified
versions of a work and requiring that the
same rights be preserved in modified
versions of the work.
Richard talking about
OpenSource and St. iGNUcius
Richard Stallman:
“Open Source misses
the point”
CURRENT CAMPAGINS
Windows 7 sins
PlayOgg
End Software Patents
Campaign for OpenDocument
High Priority for Free Software Projects
Libre Planet
Free BIOS Campaign
GNU
-
-
Millions of people are using GNU every day
to edit their documents
browse the web
play games
handle their email
as part of a GNU/Linux system on their home computer.
Even people who have never heard of it use
GNU everyday, because it powers many of the
sites they visit and services they use.
You can make a contribution by joining the FSF
as an associate member, making tax-deductible
donation and volunteering your time.
