Fype is For Your Program Execution, an attempt to build an open source scripting language from scratch (just for fun) using C99 on FreeBSD. The focus is to use as few dependencies on 3rd party libraries as possible, to use as little code as possible, and to have a very small execution binary. It should be portable to many different operating systems.
Appengine-Utilities is a collection of utility classes to aid in development on Google's Appengine. Included is a class that provided sessions. Sessions include automatic token regeneration and IP and user agent matching, with all information other than the token stored server side in both BigTable and memcache. Also included is a caching library capable of storing any object that can be pickled. The cache also uses memcache and BigTable for maximum performance and reliability.
OKL4 Microkernels are a family of second-generation microkernels based on the original designs and implementations by Jochen Liedtke. Originally implemented in highly tuned i386-specific assembly language code, the API has seen extensive development in a number of directions, both in achieving a higher grade of platform independence and also in improving security, isolation, and robustness. There have been various re-implementations of the original binary kernel interface and its higher level successors, including L4Ka::Pistachio, L4/MIPS, and Fiasco. For this reason, the name L4 now applies to the whole microkernel family including the L4 kernel interface and its different versions.
lxt (linuXtree) is a file manager program that was inspired by the popular DOS program XTreeGold. Most of the keyboard shortcuts are the same and the interface is similar, but it has been modified a bit to better suit the features of Unix such as long file names and file permissions.
Evolving Games for Unnatural Intelligence is a Java package for unsupervised machine learning based on Evolutionary Game Theory on directed graphs. It is able to segment data without any previuos information on the number of segments. It has no GUI, but implements generalizations of the original method proposed by Li, Chen, He and Jiang in the arxiv paper "A Novel Clustering Algorithm Based Upon Games on Evolving Network", published on 30 Dec 2008.
