Libdnsres provides a non-blocking, thread-safe API for resolving DNS names. It requires that your main application is built on top of libevent. The API essentially mirrors the traditional gethostbyname and getaddrinfo interfaces. All return values have been replaced by callbacks instead. The code borrows heavily from the BSD resolver library. In fact, it is an extremely ugly hack to make the BSD resolver library non-blocking and thread-safe without changing the API too much. Although it has not been tested heavily, it should compile on BSD systems and Linux. The library comes with a simple test program that can be use to verify if it works correctly.
The Platonos Projects are a group of sub projects aimed to provide Java developers with a stand-alone plugin engine as well as a pluggable Swing application framework similar to other RCP (Rich Client Platforms) available. The goal is to have an out-of-the-box runnable Swing application with the more common pieces applications contain, such as preferences, help, file I/O choosers, configuration, and more all via plugins which can be left out if not needed. Building upon the shell is very easy by simply adding plugins that provide extended behavior for existing plugins, or adding new plugins that will then be extended by other plugins.
RRDutil is a a tool to collect statistics (typically every 5 minutes) from multiple servers, store the values in RRD databases (using RRDtool), and plot out pretty graphs to a Web server on demand. The graph types shown include CPU, memory, disk (space and I/O), Apache, MySQL queries and query types, email, Web hits, and more.
HPC Challenge is a collection of benchmarks for measuring various aspects of system performance, such as flop/s, sustainable memory bandwidth, memory read/write rates, network bandwidth, and latency for parallel machines. It is designed for supercomputers, but will run on any computer with MPI-1 (Message Passing Interface) implementation and BLAS (Basic Linear Algebra Subprograms).
PACT is a self-contained set of tools which support developing and using portable programs, particularly scientific and engineering applications. By defining a single, higher level, standard programming interface, it shields application developers from the plethora of different hardware architectures and operating systems and their non-standard features.
