DeforaOS Surfer is a portable Web browser, supporting tabbed browsing on a number of platforms, including embedded environments. It notably supports either XULRunner (Mozilla), WebKit, libGtkHtml, or its own lightweight implementation as the actual rendering engine to display pages.
The Blender-Mathutils module originated from Blender, where it has been used for some years in production as a utility module for use in areas including animation, games, and mesh manipulation. This differs from 'numpy' in that it is computer graphics focused, combining Matrix and Vector types with rotation classes, which is very useful for use with animation or anywhere Euler and Quaternion values are frequently used. This project is mainly a build system around the actively maintained mathutils code in Blender to allow non-Blender related projects to make use of it. A link to the Blender repository is used so that the source never gets out of sync.
6jack is a framework for testing, analyzing, and fuzzing network applications. 6jack runs a command, intercepts calls to common network-related system calls, and passes them through an external filter. A filter can be written in any language supporting the MessagePack serialization library. 6jack is especially useful for writing tests for clients and servers, debugging and reverse engineering protocols, sketching filtering proxies, and fuzzing.
