RecDB is a recommendation engine built entirely inside PostgreSQL 9.2. It allows application developers to build recommendation applications using a wide variety of built-in recommendation algorithms such as user-user collaborative filtering, item-item collaborative filtering, and singular value decomposition. Applications powered by RecDB can produce online and flexible personalized recommendations to end-users. It is easily used and configured and allows novice developers to define a variety of recommenders that fits their application's needs in few lines of SQL. It can seamlessly integrate recommendation functionality with traditional database operations.

libcsdbg is a C++ exception stack tracer. When an exception is thrown, caught, and handled, libcsdbg offers the tools to create and process the exception stack trace, the path the exception has propagated up the call stack, unwinding it up to the section were it was handled. The traces are detailed with demangled function signatures and additional addr2line information (the source code file and line from which each function was called). libcsdbg can use all the well-known objective code file formats (a.out, elf, coff, ecoff, etc.) and can easily be used as the base for your own instrumentation code. libcsdbg transparently loads the symbol tables of the chosen dynamic libraries and of the executable, demangles function symbols to complete signatures, and binds function names to runtime addresses (even for the DSO symbols).
CT-gui is a touch-friendly GUI toolkit which can be used on the Linux desktop and on Android devices. Development can be done quickly and easily on a Linux box, then ported to an Android tablet or phone. For graphics, only OpenGL or OpenGL ES is used. For audio, ALSA is used for Linux and OpenSL ES for Android. As you might expect, the Android SDK and NDK should be installed on your system. Two demo projects called CT-synth and CT-farfisa are included, which are a polyphonic synthesizer with about 20 built-in patches, and an organ with many sounds. These can be played using the mouse or your fingers, or with an attached MIDI keyboard.
