Why PostGIS?

Pric

e

Functionality

• Open Source Geospatial Foundation– GRASS– MapGuide– Mapserver

Shuttleworth’s ”What if Java had been free?”

• PHP and LAMP might never have come into existence: lightweight integration of Java, scripting and the database

• Less reputation as “corporate overkill platform”• Even higher penetration on mobile platforms• Ruby-on-Rails might have been “Java on Rails”• More AJAX stuff would be done in Java (on the

server side), because every student with a Linux box would have Java installed by default

Open Source Java?• 2002: JCP 2.5 rules allowed Classpath, GCJ, Kaffe, Jikes, JRockit, Mono,

various embedded Java VMs – but missing complete JVM and J2SE libraries

• April 2004: Stallman’s ”Free But Shackled - The Java Trap”– The case of Brazil – Java to counter MS

• End of 2004: RedHat sponsored alternative runtime summit at MIT• May 2005: http://incubator.apache.org/harmony/

– JRE and HDK snapshots available – JRE can run popular programs like Apache Tomcat (with bugs)– More that 90% of Java 5 API complete. (not compatible, just completed) – More that 1.25 Million Lines of Code

• Soon a lot of miscommunication and confusion started: • http://lwn.net/Articles/184967/ • ” We hope that when GPLv3 is finalized we will see more code flow

between the projects and reuse of various Apache and Eclipse technologies in the GNU, Gnome and KDE worlds.”

Mambo vs Joomla!

• 2001 dual licensing, releasing Mambo under the GPL

• 2003 legal threat led to non-profit Mambo Foundation

• Developers unhappy with structure

• Oct 2006 Joomla! won Best Linux / Open Source Project at UK Linux and Open Source Awards

• Mambo is still thriving: Books on Amazon

Novell vs Oracle vs RedHat vs Ubuntu vs Debian

Letter to community

• ”We believe the future of Mambo should be controlled by the demands of its users and the abilities of its developers. The Mambo Foundation is designed to grant that control to Miro, a design that makes cooperation between the Foundation and the community impossible”

Forking

• August 17, 2005 entire 20 Mambo core developmers quit version 4.5.3

• ex-Mambo core team, with the help of the Software Freedom Law Center formed a not-for-profit organization, Open Source Matters, to provide organizational, legal, and financial support. Joomla 1.0 was released on September 16.
