Taler
Taler 		Taler is an electronic payment system offering privacy for buyers while ensuring that income is easily accounted for by the state.
 
GNUnet is a framework for secure peer-to-peer networking that does not use any centralized or otherwise trusted services. Our high-level goal is to provide a strong free software foundation for a global network that provides security and in particular respects privacy. GNUnet is a GNU package. GNUnet

GNU libmicrohttpd
GNU libmicrohttpd 		GNU libmicrohttpd is a small C library that makes it easy to integrate an HTTP server into another application. GNU libmicrohttpd is free software and part of the GNU project. The project is widely used and one of the most popular HTTP server implementations on Freecode.
 
GNU libextractor is a library used to extract meta data from files of arbitrary type. The goal is to provide developers of file-sharing networks, browsers or WWW-indexing bots with a universal library to obtain simple keywords and meta data to match against queries and to show to users instead of only relying on filenames. libextractor contains a shell command extract that, similar to the well-known file command, can extract meta data from a file an print the results to stdout. It is designed to be extendable using plugins. libextractor is a GNU package. GNU libextractor

Older Projects
CaSSiS
CaSSiS 		CaSSiS is a fast and scalable software for computing comprehensive collections of sequence- and sequence-group-specific oligonucleotide signatures from large sets of hierarchically clustered nucleic acid sequence data.
 
The Runabout is an extension of the Java libraries that adds two-argument multi-dispatch to Java without changing the language or the VM. The Runabout uses reflection to find visit methods. But instead of invoking the visit methods with reflection, the Runabout uses dynamic code generation to create code at run-time that will invoke the appropriate visit method. Runabout
 
Doodle Doodle is a tool to quickly search the documents on a computer. Doodle builds an index using meta-data contained in the documents and allows fast searches on the resulting database.
 
X10 is a new language for productive distributed parallel programming. X10

XTC XTC is a fork of the OVM codebase that focuses on delivering an extensible architecture for analysis and compilation for Java and X10 code.
 
The DUP System is a language for productive, parallel and distributed stream processing on POSIX systems. DUP is easy to learn, works well with legacy-software and has been used to improve the performance of a range of applications. The DUP System
