IPython provides a replacement for the interactive Python interpreter with extra functionality. Main features: * Comprehensive object introspection. * Input history, persistent across sessions. * Caching of output results during a session with automatically generated references. * Readline based name completion. * Extensible system of 'magic' commands for controlling the environment and performing many tasks related either to IPython or the operating system. * Configuration system with easy switching between different setups (simpler than changing $PYTHONSTARTUP environment variables every time). * Session logging and reloading. * Extensible syntax processing for special purpose situations. * Access to the system shell with user-extensible alias system. * Easily embeddable in other Python programs. * Integrated access to the pdb debugger and the Python profiler.
IrDA(TM) (Infrared Data Association) is an industry standard for wireless, infrared communication between devices. IrDA speeds range from 9600 bps to 4 Mbps, and IrDA can be used by many modern devices including laptops, LAN adapters, PDAs, printers, and mobile phones. The Linux-IrDA project is a GPL'd implementation, written from scratch, of the IrDA protocols. Supported IrDA protocols include IrLAP, IrLMP, IrIAP, IrTTP, IrLPT, IrLAN, IrCOMM and IrOBEX. The irda-utils package contains a collection of programs that enable the use of IrDA protocols. Most IrDA features are implemented in the kernel, so IrDA support must be enabled in the kernel before any IrDA tools or programs can be used. Some configuration outside the kernel is required, however, and some IrDA features, like IrOBEX, are actually implemented outside the kernel.
irqbalance is a daemon that evenly distributes IRQ load across multiple CPUs for enhanced performance.
The Irrlicht Engine is an open source high performance realtime 3D engine written and usable in C++ and also available for .NET languages. It is completely cross-platform, using D3D, OpenGL and its own software renderer, and has all of the state-of-the-art features which can be found in commercial 3d engines.
