NetPIPE is a protocol independent performance tool that encapsulates the best of ttcp and netperf and visually represents the network performance under a variety of conditions. By taking the end-to-end application view of a network, NetPIPE clearly shows the overhead associated with different protocol layers. Netpipe answers such questions as: how soon will a given data block of size k arrive at its destination? Which network and protocol will transmit size k blocks the fastest? What is a given network's effective maximum throughput and saturation level? Does there exist a block size k for which the throughput is maximized? How much communication overhead is due to the network communication protocol layer(s)? How quickly will a small (< 1 kbyte) control message arrive, and which network and protocol are best for this purpose? For a paper fully describing NetPIPE and sample investigation of network performance issues using NetPIPE, see the homepage.

Railsbench is a small collection of ruby scripts which make measuring raw performance of rails apps a snap. All tests are run from the command prompt, making performance regression testing easy.

Sipp is a performance test tool / traffic generator for the SIP protocol. It comes with a few basic SipStone user-agents scenarios (UAC & UAS), i establishing and releasing multiple calls with the INVITE and BYE methods.

This stress test suite will stress a computer system in various selectable ways It was designed to exercise various physical subsystems of a computer as well as various operating system kernel interfaces.

Babel is a program designed to interconvert a number of file formats currently used in molecular modeling. Babel is capable of assigning hybridization, bond order, and connectivity when these elements are not present in the input file.

FastTree infers approximately-maximum-likelihood phylogenetic trees from alignments of nucleotide or protein sequences. FastTree can handle alignments with up to a million of sequences in a reasonable amount of time and memory.

This is GDT (graphics data text) format translator written in C/C++ that converts a binary gdsii file to a text format that is compact and easy to parse.

Gdspy is a Python module for creating GDSII stream files, usually CAD layouts. It includes a layout viewer for the geometries created, and it can also be used to import and merge GDSII files.

Open Chinese Convert (OpenCC) is an open source Simplified-Traditional Chinese conversion project, providing high quality thesaurus and libopencc, as well as a conversion utility and a dictionary generator.

This modules requires Lingua::ZH::TaBE, a Chinese Tokenizer on steroids; it's a thin wrapper around Lingua::ZH::TaBE, as well as its interface with overload and utf8 semantics.
