TnFOX is a modern secure, robust, multithreaded, exception aware, internationalizable, portable GUI toolkit library designed for mission-critical work in C++ and Python, forked from the FOX library. It replicates the Qt API in many places, comes with a full set of Python bindings, and has been designed primarily for Tn, the port of Tornado to FOX.
nedtries is a portable in-place bitwise binary Fredkin trie algorithm that allows for near constant time insertions, deletions, finds, closest fit finds, and iteration. It is approximately 50-100% faster than red-black trees and up to 20% faster than O(1) hash tables. It provides implementations as C macros, C++ templates, and as a C++ STL compatible associative container.
