Software development Software can be developed in C using the Maemo SDK, Java (which is supported by the Jalimo JVM), Python, Ruby, Mono, Vala, Perl and Pascal. The Maemo SDK is based around the Debian-oriented Scratchbox Cross Compilation Toolkit, which provides a sandbox environment in which development may take place. Scratchbox uses QEMU to emulate an ARM processor or sbrsh to remotely execute instructions. Scratchbox-compatible rootstraps are available for both x86 and ARM, so the majority of development and debugging takes place on x86, with final packaging being for ARM. 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. This will change with the Harmattan release, which will add the Qt library as the default, with GTK+ becoming community-supported. The programming languages Python, C and C++ will also be supported. The Nokia Developer Wiki community has articles about Qt development, and includes tutorials and articles about development for the Maemo operating system. Hardware The Maemo operating system is designed for Nokia Internet Tablets, which feature very similar specifications to Nokia's high-end N-series and E-series cellphones, with TI OMAP ARM SoCs, large screens, and expandable internal storage. 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 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. Version history OS2005 Shipped with the 770 in November 2005, this is the original Internet tablet OS. It came bundled with the Opera web browser, Flash 6, basic email and RSS clients, audio and video players, PDF and image viewers, a graphical Advanced Packaging Tool, front-end (dubbed simply "Application manager"), and a variety of simple games and utilities. OS2006 On 16 May 2006, Nokia announced a new version of Internet Tablet OS, which was subsequently released as a beta version for the 770 on 9 June 2006 and as a production version on 20 June
