An example -- Building Handhelds with GNOME software • We wanted to

• Align with a popular Desktop platform (both code and people)

• Make it easy to port Desktop applications

• Customize the look & feel to get the Nokia look & feel

• Work with others on common components – shared maintenance

• GNOME offered• Popular, stable developer platform

• Good options for customization

• Vibrant, business friendly developer community

• Transparent development process and a level field for participation

Development and the maemo site

• Maemo supports application development for the Internet Tablets • Tools & support

• A place to publish your work (Application Catalog)

• New @ maemo: We invite others to participate at our product development in areas that are not developed elsewhere

• Garage.maemo.org hosts software projects related to the Internet Tablets

• Bug reporting, feedback and code examples that Nokia can productize

• Maemo Sardine

Maemo Sardine @ http://sardine.garage.maemo.org/• The Maemo Sardine is a bleeding edge distribution of Maemo's Hildon

Application Framework (HAF) for the Nokia Internet Tablets.

• It is for application developers and hackers

• Enables Maemo application developers to follow the latest changes to the HAF. They can test their applications against the latest changes before the final product hit the streets

• Enable anybody to participate in the development of the Nokia firmware and see where it’s heading at

Benefits of Open Source

• Cost savings• Utilizing available components as such• Improving and then using components and subsystems

• Quality & Flexibility• Visibility• Access to code

• Speed & Time• Kick-start with available components• Accelerate with familiar technologies

• Software in-licensing• Done in advance

• Available developers• Roadmapping & future

• Visible • Can be influenced through discussions• Can be changed by showing up with good code

Challenges

• From hacking to stabilizing• The Big Shift inside the development

• Architecture management• New aspects

• Additional investments• Community work

• Product vs. community focus• Different cultures

• Upstream vs integration

Next with the products

• Short term• better Flash performance

• better video performance and quality

• longer usage times i.e. better power management

• fixes here and there

• Mid term --later this year we'll have an• updated browser with better WEB 2.0 support and other goodies

• improved multimedia support with more formats supported

• improved package management to better enable sw upgrading

• interesting 3rd party software such as Skype and Real Rhapsody

• more apps & stuff downloadable from http://tableteer.nokia.com/ (can be accessed with an internet tablet, only ....)

Summary

• Open source provides a very pragmatic way of building consumer product software

• Our approach includes• Utilization of ready components

• Participation in upstream projects

• Nokia builds on top of that, integrates, tests, and releases

• Benefits are clear• Speed & flexibility & cost

• Challenges must be handled properly

• Two don'ts• Do not mix reality & dreams!

• Do not prevent change!
