Producing Open Source Software
How to Run a Successful Free Software Project

At parties, people no longer give me a blank stare when I tell them I write free software. "Oh, yes, open
sourcelike Linux?" they say. I nod eagerly in agreement. "Yes, exactly! That's what I do." It's nice not
to be completely fringe anymore. In the past, the next question was usually fairly predictable: "How do
you make money doing that?" To answer, I'd summarize the economics of open source: that there are or-
ganizations in whose interest it is to have certain software exist, but that they don't need to sell copies,
they just want to make sure the software is available and maintained, as a tool instead of as a commodity

History of OSS ( 1980)
Milestone 1980Before 1980: Sharing was common use- Hardware was not compatible (no standards)- There was no internet sharing was not simple
Pre 1980: Hardware was a differentiatorMachine depended (Assembler)No high level programming languagesSharing software was common practiceSoftware became USPSoftware became protected
1986
IBM approached Microsoft in July 1980 to provide the operating system for its upcoming personal computer. For this deal, Microsoft bought a system called 86-DOS from a company called Seattle Computer Products and, after adapting it for the PC, delivered it to IBM as 'PC DOS' in exchange for a one-time fee of $50,000.
History of OSS ( 1980)
1980: source code of laser printer missing
Xerox 9700
Milestone 1980Richard Stallman worked in the Artificial Intelligence Lab at theMassachusetts Institute of Technology in the 1970s and early '80s- In 1980, Stallman and some other hackers at the AI Lab were refused access to the source code for the software of a newly installed laser printer, the Xerox 9700. Stallman had modified the software for the Lab's previous laser printer (the XGP, Xerographic Printer), so it electronically messaged a user when the person's job was printed, and would message all logged-in users waiting for print jobs if the printer was jammed. Not being able to add these features to the new printer was a major inconvenience, as the printer was on a different floor from most of the users. This experience convinced Stallman of people's need to be able to freely modify the software they use
Stallman wrote:The modern computers of the era, such as the VAX or the 68020, had their own oper-ating systems, but none of them were free software: you had to sign a nondisclosureagreement even to get an executable copy.This meant that the first step in using a computer was to promise not to help yourneighbor. A cooperating community was forbidden. The rule made by the owners ofproprietary software was, "If you share with your neighbor, you are a pirate. If youwant any changes, beg us to make them."

Richard Stallman
Biggest accomplishment: GNU licenceGNU General Public License (GPL)
In effect, it uses copyright law to achieve an effect opposite tothat of traditional copyright: instead of limiting the software's distribution, it prevents Anyone , even the author, from limiting distribution. For Stallman, this was better than simply putting his code into the public domain. If it were in the public domain, any particular copy of it could be incorporated into a proprietary program (as also sometimes happens to code under permissive open source copyright licenses)Tools:- Emacs

Other initiatives
- Berkeley Software Distribution (BSD)
AT&T loosley proprietary research project
(late 1970)
- X Window System (MIT) (mid 1980)
- Tex (free, publishing-quality typesetting
system)
Motivation: the pleasure of working with like-minded collaborators,or even by a simple human desire for glory. Software must run: common interest to work together + high quality code as a result- it was just better code.
Businesses are already using open source software in day2day operations.
Free vs Open
Free as in the freedom to speech, not as in free beer
Motivation: software becomes more and more important; more and more systems and lives depend on it; so it should be free (and open)
Browser war: Netscape vs Microsoft internet explorer (1990)This was a first war for data-sharing?
Getting started
The cathedral and the bazaar
http://www.catb.org/~esr/writings/cathedral-bazaar/
Basic principles
Identify a need
Develop a software prototype
Build a community
Set an ecosystem, withUsers
Developers
Architects
Service providers
All working together and playing by the rules
Look and feel matters! *New
Every good work of software starts by scratching a developer's personal itch.
Don't reinvent the wheel
Don't reinvent the wheel
What next?
Transforming private vision into a public one
Mission statement:
Geomajas is the open source platformto create Web GIS applications
Explain the project
integrate data real time from several sources into one easy to deploy map in a way the users can understand the information presented and can act upon the data as if it where real world objects
What next?

Working together
Be as open about your organization's goals as you can without compromising business secrets
Business goals differ with every project
Ex: Google / Facebook / university / SME / freelancer / employee / government
Money
Most free software is written by paid developers
Financial backing is good for the sustainability
Can also divide a project in two groups!
Respect non paid contributions!
Money influences the project, so does adding time.
All OSS is commercial software
What money can't buy
Commit rightsParticipating in the decision processGet respect in the community
Even as a sponsor, obey the rules!Be authenticExplain Why
Commit rightsParticipating in the decision processGet respect in the communityYou are being watched!

Quote
"Hire and promote first on the basis of integrity; second, motivation; third, capacity; fourth, understanding; fifth, knowledge; and last and least, experience. Without integrity, motivation is dangerous; without motivation, capacity is impotent; without capacity, understanding is limited; without understanding, knowledge is meaningless; without knowledge, experience is blind." Dee Hock, founder of Visa.
