Originally developed on IRIX, Freeciv has been ported to many different operating systems: it is distributed with many Linux distributions, offers installers for Microsoft Windows, and has been known to run on Mac OS X, Solaris, Ultrix, QNX, OS / 2, Cygwin, AmigaOS, RISC OS, Maemo, ZETA, SkyOS and various BSDs.

The most common mobile operating systems ( OS ) used by modern smartphones include Google's Android, Apple's iOS, Nokia's Symbian, RIM's BlackBerry OS, Samsung's Bada, Microsoft's Windows Phone, Hewlett-Packard's webOS, and embedded Linux distributions such as Maemo and MeeGo.

Nokia's Symbian operating system features a barcode scanner which can scan barcodes, while mbarcode is a barcode reader for the Maemo operating system.

GStreamer also operates in embedded devices like the Palm Pre, and the Nokia 770, N800, N810, N900 and N9 Internet Tablets running the Maemo operating system.

There are apps for the iPhone, and the Nokia internet tablet running the Maemo operating system.

* Until they were removed from the Maemo operating system application installer in January 2010, certain advanced features were unlocked by a " Red Pill Mode " easter egg to prevent accidental use by novice users but make them readily available to experienced users.

* Lenovo announced it would ship select models with SUSE Linux Enterprise Desktop pre-installed For instance Google's Android mobile operating system, Nokia's Maemo and HP's WebOS mobile operating system run on the Linux kernel.

The platform comprises the Maemo operating system and the Maemo SDK.

Since Diablo ( Maemo 4. 1 ), Maemo supports " Seamless Software Update " ( SSU ), which allows incremental operating system upgrades " over the air " using the Advanced Packaging Tool, without the need for a full flash with every update.

The ability to run largely unmodified linux packages sets Maemo apart from other Linux-based mobile operating systems, such as Android and webOS.

As a new feature of the Maemo operating system, Maemo 5 offers the Qt library as a community-supported component, alongside the officially supported GTK + backend.

The NOKIA Developer Wiki community has articles about Qt development, and includes tutorials and articles about development for the Maemo operating system.

Although the highly optimized, hardware-specific nature of Maemo renders its operation on non-Internet tablet hardware very difficult, most of the important non-proprietary parts of the operating system, along with some of the available third-party party applications, are actively being packaged for Debian and are available for use on other distributions, which will open up a large range of other hardware options.

Nokia runs the Maemo operating system on the Nokia N900 and Nokia N9.

Maemo 5, also known as Fremantle, is the default operating system on the Nokia N900.

An open source Linux project called Mer, a variant of Maemo, has been formed to provide an alternative, fully open operating system for mobile devices including the Nokia N800 and N810.

The UK cellular operator Vodafone has its own branded, somewhat more restricted version of the Maemo 5 operating system.

The Maemo 5 operating system comes preloaded with a variety of applications such as:

Harmattan was a transitional operating system developed by Nokia, which was planned to be a bridge between Nokia's Maemo and the MeeGo project.

A fully playable port has been produced for the Wii, GP2X portable game system, the Pandora handheld, and the Maemo 5-based N900 smart phone.

SSU, in particular, is one of the most significant parts of the Diablo release, as it eliminates the flash-based upgrade system of previous Maemo releases which required the user to completely wipe their device with each upgrade.

Mer is a completely open-source alternative operating system targeting mobile and embedded systems, first developed for reimplementing Maemo in the open, and then rebased on top of the MeeGo tools.

Although a Windows, Linux, and Maemo version are available, it is primarily designed for the Sony PSP.

) do not support OpenVPN, it is available for Maemo, Windows Mobile 6. 5 and below, jailbroken iOS 3. 1. 2 + devices, Android 4. 0 + devices, and Android devices that have had the Cyanogenmod aftermarket firmware flashed or have the correct kernel module installed.

For the Maemo and MeeGo platforms there is mDictionary, which among other dictionary formats, supports StarDict.

* Conboy is a Tomboy port to the Maemo platform written in the C language

Maemo is a software platform developed by Nokia and improved upon by the Maemo community for smartphones and Internet tablets.

Maemo is mostly based on open source code, and has been developed by Maemo Devices within Nokia in collaboration with many open source projects such as the Linux kernel, Debian, and GNOME.

Maemo is based on Debian GNU / Linux and draws much of its GUI, frameworks, and libraries from the GNOME project.

The user interface in Maemo 4 is similar to many handheld interfaces, and features a " home " screen, which acts as a central point from which all applications and settings are accessed.

The Maemo 5 user interface is slightly different ; the menu bar and info area are consolidated to the top of the display, and the four desktops can be customized with shortcuts and widgets.

Up to Maemo 4 ( AKA OS2008 ), the default screen is the " Home " screen — the central point from which all applications and settings are accessed.

The user interface in Maemo 5 is different to its predecessors.

Maemo is a modified version of the Debian Linux distribution, slimmed down for mobile devices.

Although Maemo is based on Linux and open source software, some parts of Maemo remain closed source.

Due in part to the free and open source nature of Linux and Maemo, porting applications to Maemo is a straightforward procedure.

Software can be developed in C using the Maemo SDK, Java ( which is supported by the Jalimo JVM ), Python, Ruby and Mono.

The Maemo SDK is based around the Debian-oriented Scratchbox Cross Compilation Toolkit, which provides a sandbox environment in which development may take place.

Diablo is the codename for the OS2008 Feature Upgrade ( corresponding to Maemo 4. 1 ), released in June 2008.

Scratchbox was designed for the Maemo development platform ( Nokia 770, N800, N810 Internet Tablets and Nokia N900 and N9 phones ) and supports ARM architecture and x86.

* Maemo, MeeGo – Qt for Maemo, merged with Moblin to MeeGo ; many applications are already written for Maemo based on the prior Internet tablets ; the Nokia N900 also supports Qt ; the Forum Nokia Wiki has quality-controlled articles supporting Qt development ; mhe Maemo has a development group on Forum Nokia Wiki at Forum Nokia Wiki Maemo.

Also, there are implementations for Windows CE, Windows Mobile, Maemo, MeeGo and Android available for separate download.

Maemo ( rebranded MeeGo in 2010 ), a Debian Linux based graphical user environment, was developed for the Nokia Internet Tablet devices ( 770, N800, N810 & N900 ).

Nokia entered the tablet space with the Nokia 770 running Maemo, a Debian-based Linux distribution custom-made for their Nokia Internet Tablet line.

* Fremantle, the code name for Maemo 5, a mobile Linux distribution developed by Nokia for the N900 phone
