libktomgirl is a library that reads a subset of the Tomboy file format. When it's done, it should support reading and writing all aspects of files created by Tomboy, Gnote, and KTomGirl. Despite the K in its name, there are no KDE or Qt dependencies (nor C#, GKT, or GLIB). This is pure C++ with boost and stdlib only. Most of the code is from Gnote.
4K Video Downloader is a video and audio downloader for YouTube, Vimeo, Facebook, Dailymotion, Metacafe, and other video-sharing services. It features video quality up to 4k resolution, FLV, MP4, and MKV support, extraction of audio to the MP3 format, and a "Smart Mode" for fast downloads.
ImageVis3D is a volume rendering application specifically designed to render large data sets. This is achieved by splitting the data set into multiple levels of detail (LoD), with each level itself decomposed into multiple bricks (atomic rendering primitives). Interaction occurs at the coarsest LoD, which can be rendered instantaneously on almost all modern systems. After a configurable delay, ImageVis3D will successively render finer levels of detail, until the data are visible at their native resolution. Volume rendering, as the name implies, is a technique for rendering scalar volumes of data. The rendering method allows one to see "inside" a data set, allowing the user to understand the inner three-dimensional structure of the data.
LIME is a dynamic programming language with a LISP-like syntax. It features partial function application, eager and lazy evaluation, call-by-value and call-by-reference, macros, reading/writing LIME code as data, a standard library including infinite streams, and an interactive mode with auto-indentation.
Metacza is a language and its compiler which produces output in the C++ Meta Template Language. Its concise syntax makes Meta Template Programming much easier. Metacza allows you to write programs using boost::mpl, and to produce C++ header files that can be used on their own. Programming without boost::mpl is also supported. Metacza is a higher order language with closures, let, and lambda.
