Galet is a peer-to-peer application which primarily aims to provide easy-to-setup, secure communication channels between the computers of people who know and trust each other. Its secondary goal is to create a public network based on these channels. No direct connections occur between two nodes that have not been explicitly accepted by the users of these nodes. This makes the network very difficult to censor, as an attacker's direct access to the network is limited.
JCons provides a library that bring color to your Java console. The Java console gives no methods to change the foreground or background color. With help of this library, one can make error messages red and success messages green, for example. Most Unix terminals can deal with ESC sequences, so they are used to make the Java console colorful.
libUTL++ is a C++ class library that includes a wide range of highly re-usable functionality and abstractions. It uses templates in some places, but generally favors an object-oriented design. The library covers functionality in areas such as containers, text processing, memory allocation, date/time manipulation, stream I/O, data compression, and others. It also includes abstractions to facilitate common tasks such as object copying, comparison, serialization, etc.
MiniCppUnit is another C++ port of the famous JUnit framework for unit testing. Unlike CppUnit, MiniCppUnit follows a minimalistic approach. The basic features are the same, but in only about 500 lines of code. No library installation is needed. Extra features include color highlighting to locate differences on failing string asserts, floating point asserts which consider NaNs, Infs, and using epsilon values which are relative to the expected value, assertions for the dynamic type information, and more.
