seamless updates

code in your hands

Seamless software updatesCurrently updates via flasher are problematic because the applications installed by the users need to be reinstalled manually.

● Internet Tablet OS and 3rd party applications updated via APT.● Easy for users to install and update 3rd additional software.● Reflashing the device as a secondary method

Future releases

code in your hands

Identified future releases● maemo and the Internet Tablet OS to share wind codenames and version numbers.● Codenames don't reveal major/minor releases, release dates or new devices.● Useful tool to communicate plans to the maemo community and Nokia partners.● They follow the alphabet: after B(ora) will come C, D, E, F...● Bora and the 3.x series will be followed by maemo 4.0 Chinook. Then Diablo. Then Elephanta...

Future releases API management

code in your hands

Consolidating API management● Chinook will bring another API break, needed for the alignment with GTK+ upstream (from 2.6 to 2.10).● Developers can partially test applications on top of Sardine already.● Plan to release alpha and beta SDKs to facilitate porting before Chinook launch.● From Diablo onwards we aim to keep backward compatibility in justified API breaks to grant platform stability.● We depend from upstream breaks, though.

Hildon goes upstream

code in your hands

Hildon goes upstream● User environment designed for mobile devices with a strong focus on usability and attractive look & feel.● Originally designed for touchscreen input with a stylus or thumb.● First developed for Nokia Internet tablets, now aiming to support several form factors as well.● Built on top of the GNOME Mobile and Embedded platform.


code in your hands

Hildon goes upstream● Provides a set of libraries, a theme framework, the Hildon desktop, an input methods framework and UI guidelines to build applications.● Plugin interfaces to extend Hildon.● Language bindings. So far it supports Python and C++. Other languages under consideration.● All components have accessibility support, especially to allow automatic UI testing with tools like Dogtail.


code in your hands

Hildon goes upstream● Aligned with maemo strategy but following upstream rules.● Entrance requested to GNOME.● If accepted: code, bugs, patches, docs & list in *.gnome.org
