appserver.io is a multithreaded application server for PHP. Applications can be installed using drag and drop. It has outstanding performance, with benchmarking on nginx showing that it is about 50% faster than nginx alone (based on a standard Magento installation) with no additional tweaks.
Gcmc is a front-end language for generating G-code, SVG, and DXF for CNC mills, lathes, laser cutters, and other numerically controlled machines employing G-code, SVG, or DXF. The language is a context-free grammar created to overcome the archaic format of G-code programming, but can be used more generally for many targets. Gcmc aims to be more readable and understandable than G-code and enable programmatic designing. Gcmc makes extensive use of vector mathematics to support the 3D nature of CNC machining. It handles units as millimeters, mils (inch), degrees, and radians and performs automatic conversions where necessary.
Libfbm is a C++ library for fast and accurate bulk-simulation of multi-dimensional (1D, 2D, 3D, .., 8D) Gaussian stationary processes, fractional Brownian motion, and fields with power-law power spectrum. It makes use of the circulant matrix embedding and FFT. Random number generation is provided by SFMT (SIMD-optimized Mersenne Twister) with a ziggurat based algorithm for normal distribution. For FFT functions, it depends on the FFTW library.
Griffon is dekstop application development platform for the JVM. Inspired by Grails, it leverages the Groovy language and concepts like convention over configuration. The Swing toolkit is the default UI toolkit of choice however others may be used, principaly SWT and JavaFX. Developers may use a combination of the Groovy and Java as well as other JVM languages such as Scala, Clojure, Mirah, and Jython. It encourages the use of the MVC pattern and follows in the spirit of the Swing Application Framework (JSR 296) by defining a simple yet powerful application life cycle and event publishing mechanism.
Wu is small command-line application that retrieves weather data from Weather Underground (including current conditions, historical data, forecasts, active alerts, and station lookup). The program is designed to be extremely fast and generally compliant with the Unix philosophy. Wu is written in Go, and requires a Go compiler to build from source.
tcpdump prints a description of the contents of packets on a network interface which match a given boolean expression. It can also be run with the -w flag, which causes it to save the packet data to a file for later analysis, and/or with the -r flag, which causes it to read from a saved packet file rather than to read packets from a network interface. In all cases, only packets which match the expression will be processed by tcpdump. tcpdump logs more than just TCP, IP, or ethernet packets, but has a whole suite of decoders, including ones for USB.
