Quality Awareness



code in your hands

Seamless software updates
Currently 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

Shared roadmap
All platform features to be announced there.

Invitation to
request

announce 3rd
party plans.


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.


Clean architecture

Clean architecture
Fix dependencies between open source
●

components and Nokia proprietary.
● Reach hardware abstraction.

● Define feedback wished for each area.

Clean architecure Hildon2upstream



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

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

Aligned with maemo strategy but following
●

upstream rules.
● Entrance requested to GNOME.

● If accepted: code, bugs, patches, docs &

list in *.gnome.org 3 party rd
