Nokia N900 - Maemo5 OS FULL Review & Info >>>

INTRO

Maemo Community is an open source community developing software around the Maemo platform. The Maemo community has over 16,000 registered Users that contribute to more than 700 development projects. We work with open source tools and processes. We develop new software for both the platform itself and on top of the platform. Applications developed with the Maemo SDK are used today by thousands of consumers.

Maemo is a software platform that is mostly based on open source code and powers mobile devices such as the Nokia N810 Internet Tablet and NOW its on the NEW Nokia N900. Maemo platform has been developed by Nokia in collaboration with many open source projects such as the Linux kernel , Debian , GNOME , and many more.

ABOUT

Maemo OS Platform

The Maemo platform consists of the software stack from the Linux kernel to the Maemo APIs and the Hildon UI framework. Commercially available devices running on Maemo come with the pre-installed Hildon UI and a set of applications delivered by Nokia. It is possible to develop other UIs on top of the Hildon UI framework.

Maemo platform is based on Linux operating system which itself inherits its architecture from the Unix operating system. Linux and other open source projects contributing to the Maemo platform embrace sharing of source code, collaboration and open development model. The Maemo community promotes these values by keeping the Maemo platform open wherever feasible, by sharing source code, and by contributing code directly to the upstream projects.

System Services

The primary communication channel between applications is DBUS. DBUS also provides a channel for interaction between the system and applications. DBUS is used to invoke all the applications by sending messages.

System Services provide a SQL database (SQLite 3) that can be used to store user application data. SQLite database is accessed through a library interface.

System Services provides also system-wide services to applications and end users. The services include device state management (DSM), mode control (MCE), battery management (BME) and few graphical user interface elements to manage the behavior of the services.

OS Features

Third-party applications

Due in part to the free and open source nature of Linux and Maemo, porting applications to Maemo is a straightforward procedure. Because of this, there are many third-party applications available for the platform. Some applications are original software written specifically for Maemo, while other applications are straight ports of existing Linux programs. Some notable software includes:
Media players: Canola (with network streaming), MPlayer
Internet: Claws Mail, Modest, Midori, Mozilla Fennec
Office applications: Gnumeric (spreadsheet), Abiword (word processing)
Instant Messaging: Pidgin
VOIP: Gizmo Project, Skype
Games: The Battle for Wesnoth
Others: FBReader (e-book reader), GPE (OpenSync compatible PIM), rdesktop (RDP remote access), Rhapsody (subscription music, US only), ScummVM (game emulator), Wayfinder (fully featured GPS navigation software), Free42S (HP 42S calculator emulator), gPodder (podcast client), Maemo Mapper (includes GPS functionality), MaemoMyth (MythTV frontend that uses GMythStream), Monsoon HAVA (TV viewer and controller), Navit (GPS navigation software), Obscura Photo Manager, Palm Emulator from Access (ARM based Palm emulator), Phonelink (SMS and voice caller via BT), Quiver Image Viewer, SDict Viewer (sdict-based dictionary/encyclopedia viewer), Vagalume (Last.FM player), VNC, YouAmp (music player), LogMeIn Browser Plugin
Debian: The complete ARM Debian distribution can be installed as a Maemo application.[12], making thousands of software packages available (including OpenOffice, Firefox, Java, the GNOME desktop, etc).

Hildon UI Framework

The user interface framework is based on the X Window System having the Matchbox window manager. The API on top of X is the GTK+ widget toolkit with so-called Hildon extensions. GTK+ is the UI framework developed in the GNOME project. The Hildon UI framework provides components on top of the GNOME components to support control panel, status bar, task navigator, and home applets.

Maemo Launcher

Maemo Launcher launches all applications on the Maemo platform. It is there to speed up application startup by sharing some of the initialization data of an application startup. Maemo Launcher is composed of two parts: the Maemo-invoker, which is executed by a DBUS daemon or scripts to start the given service, and the Maemo-launcher, a server that has initialized most of the data used by the applications. The Maemo-invoker asks Maemo-launcher to start the actual application.
