Cerridwen provides geocentric planetary data suitable for a broad spectrum of astronomical and astrological applications, with a focus on our solar system. Among its data you will find, for example, the time of the next sunrise or that of the last full moon, or simply the current tropical position of the sun. It comes with a simple command-line utility and a JSON server, but is also designed to serve as a basis for your own application.
pyforward is a GTK+ front-end to three core Linux technologies that make it possible to turn your computer into a WiFi access point in infrastructure mode.

libstudxml is a streaming XML pull parser and streaming XML serializer implementation for modern, standard C++. It has an API which the authors believe should have already been in Boost or even in the C++ standard library. It is compact, external dependency-free, and reasonably efficient. The XML parser is a conforming, non-validating XML 1.0 implementation which is based on tested and proven code.
GDRSImageCache is a minimalistic caching and image resizing library for iOS. Given a URL, it retrieves the image in a background thread and it caches it in memory. GDRSImageCache can be provided with a filtering block which can be used to resize the images obtained from the URL before caching.
twyg lets you visualise arbitrary tree structures in a pretty way. The appearance of the tree (layout, color, node, connection shapes, etc.) is fully controlled via configuration files in a generative way. This means that almost all visual properties of the output can be controlled by expressions that depend on the characteristics of the tree (e.g. the color or shape of a node can be a function of its hierarchical position in the tree). This allows for crafting very flexible configurations that can be applied to trees of arbitrary size and complexity. It supports the Cairo and NodeBox1 rendering backends.
