PRUN is a cluster job scheduler and parallel task executor system for Linux/Unix systems. Like other full-featured batch systems, it provides a job queueing mechanism, job scheduling, a priority scheme, resource monitoring, and resource management. PRUN is a simple, easy-to-use, full-featured, stable solution to run short-term or long-term jobs across the cluster.
KeyBox is a Web-based SSH console for executing commands and managing multiple systems simultaneously. It allows you to share terminal commands and upload files to all your systems. Once the sessions have been opened you can select a single system or any combination on which to run your commands. Also, additional system administrators can be added and their terminal sessions and history can be audited.
Weed-FS is a simple and highly scalable distributed file system. There are two objectives: to store billions of files, and to serve the files fast! Instead of supporting full POSIX file system semantics, it implements only a key-file mapping. Instead of managing all file metadata in a central master, it manages file volumes in the central master and lets volume servers manage files and the metadata. This relieves concurrency pressure from the central master and spreads file metadata into volume servers' memories, allowing faster file access with just one disk read operation. It is modelled on Facebook's Haystack design paper. Only 40 bytes of disk storage are required for each file's metadata, and disk reads are O(1).
uma::bson is a DOM-style C++ API for reading/writing BSON data. Unlike the MongoDB C++ API, which exposes a read-only interface with a separate interface for creating a BSON representation, this API allows reading/writing on the existing data. The API is designed primarily for serialising/deserialising BSON data to/from streams (files, socket connections, etc.).
Overthere is a Java library to manipulate files and execute processes on remote hosts, i.e. do stuff "over there". It was built for and is used in the XebiaLabs deployment automation product Deployit as a way to perform tasks on remote hosts, e.g. copy configuration files, install EAR files, or restart Web servers. Another way of looking at it is to say that Overthere gives you java.io.File and java.lang.Process as they should have been: as interfaces, created by a factory and extensible through an SPI mechanism.
Rerun is a lightweight tool-building framework useful to those implementing management procedure with shell scripts. It will help you organize your implementation into well-defined modular interfaces. Collections of management modules can be archived and delivered as a single executable to facilitate team handoffs. Using the "stubbs" module, rerun will even facilitate unit tests. When users execute rerun module commands, rerun can record execution data into log files which can later be replayed.
District Builder is a software application designed to give the public transparent, accessible, and easy-to-use mapping tools to draw the boundaries of their communities or to generate redistricting plans for their state and localities. The drawing of electoral districts is among the least transparent processes in democratic governance. All too often, redistricting authorities maintain power by obstructing public participation. The resulting districts embody the goals of politicians to the detriment of the representational interests of communities and the public at large. With District Builder, the public has the capacity to create and submit district plans for municipal, county, and state governments, support redistricting competitions, and keep the entire process open. In addition to legislative redistricting, District Builder's flexibility accommodates school districts, police districts, and many other redistricting needs.
