www.bartholo.com/OSCON/
Goals
‣ Learn how the core M&E Community projects
have been the catalyst for numerous ports,
extensions, and expanded open source uses
not previously envisioned when the
community launched.
Java Momentum
6 Billion Java-Enabled Devices
2.5 Billion Java-Enabled Phones
3.5 Billion Java Card
20 Million Java Set-top Boxes
800 Million Java Desktops
180 Operators Deploying
Java Content
6 Million Developers
Why Open Source?
•Bring communities together
and extend them
•Engage platform and
application developers, ISV's,
tools vendors, and operators
•Industry-wide collaboration
on platform, tools, and
applications
•Remove inefficiencies and
barriers to innovation
•Drive common
implementation and
consistency
