Limbo is a PC Emulator (x86) based on QEMU for Android devices. It lets you run a Desktop OS like Debian or DSL Linux on your Android device with Network and X Windows. Limbo works with Live CD ISOs and pre-installed hard disk images created with QEMU, VMWare, Bochs, or Virtual PC emulators.
LibLogicalAccess is an RFID library developed in C++ for Linux/Windows, also available on C# for use on Microsoft operating systems (using a COM wrapper). It provides low-level commands access and high-level generic abstraction for several chips and readers (PC/SC readers like OMNIKEY, STid readers, etc.) on 125Khz (EM4102, HID Prox, etc.), 13.56Mhz ISO14443/ISO15693 (Mifare Classic, Mifare DESFire, HID iClass, etc.), and 433Mhz frequencies.
Multi-Sandbox Lua Engine (MSLE) is a modified Lua interpreter which supports creation and maintenance of multiple "100% tight" sandboxes from within Lua. "100% tight" means that the amount of memory used by a sandbox (counting both code and data) is strictly limited, a feature Lua did not offer before.
ColDet 3D Collision Detection Library is a library that provides collision detection for generic polyhedra. Its purpose is mainly for 3D games where accurate detection is needed between two non-simple objects. It also includes a fast multi-object system that quickly prunes the space of pairs to be checked, and additional support functions such as tests for ray picking.
