STB microservices are a set of workhorse tools for maintaining scientific digital image repositories. The tools implement photo renumbering, metadata harvesting (OAI-PMH), use of GLite for very large batch processing, Web-based high-resolution viewers, processing, long-term preservation, and more.
iCan is an intelligent, community-driven command line that helps you to automate any kind of task arising in your daily Linux use. It is extensible through simple Lua modules, which run in a sandbox environment. It is designed to learn what you do and make things easier for you, every time you do something.
webtools.class is a PHP class of useful functions for websites, including connecting to MySQL (with error reporting), IP-to-location information, creating salted MD5 passwords and validating MD5 passwords, shortening URLs with the Bitly API, email validation, and sanitizing user input.
WHDD is a HDD diagnostic and data recovery tool for Linux. It can test a hard drive with reads and writes, while providing intuitive visualization of the process. It also has a function for copying a device, with algorithms optimized for least harm to already-defective source devices. It works with your hard drives at a low level by sending ATA commands, which means that the system doesn't freeze while accessing damaged devices (the device is soft-reset on timeout).
Hados stores files in a cluster of servers. Its goal is to handle high availability by storing copies of the same file on several nodes. It provides RESTFUL APIs to easily store, check, or retrieve files. Using the cluster APIs, you can retrieve files from whichever node hosts them. To avoid any single point of failure, it is possible to apply a request to any node of the cluster; there is no master node.
phpEquations is a PHP class that can find the solutions of linear, polynomial, and trigonometric mathematical equations and systems. It takes a string with one or more equations and parses it to solve the equations. The solutions are returned as an associative array with the values of each equation variable. The class uses a variation of Newton's method with a special technique, called Blocking, to maximize speed by reducing a large problem into smaller problems with fewer variables. The time limit for running the algorithm, the number of variables, the number of iterations, and the iteration step are configurable parameters.
PHP Clarke and Wright Algorithm is a class that can solve a truck routing problem with the Clarke and Wright algorithm. It attempts to solve the problem of determining the routes by which a given number of trucks with different weight and volume capacity will be dispatching deliveries to a certain number of clients distributed geographically within certain time windows. The class takes as parameters the nodes of positions of each client, the demands of each client, a matrix of distance between nodes, and the capacity of each truck. It computes the route for each truck, as well the time and distance to drive to each customer and the volume and weight to transport.
make3_80-sh is a compatibility layer for GNU make 3.80. Starting with 3.81, GNU make treats backslash newlines in commands in a POSIX-compatible way. This breaks older Makefiles. make3_80-sh is a compatibility layer to use old Makefiles with GNU make 3.81. It also aids migration of such Makefiles.
