EC2Dream Fogviz is a visual tool for building and managing cloud servers. It combines Fog, Ruby, and Chef into a tool that is particularly helpful when developing and testing Chef automation scripts. It currently supports Amazon AWS, Eucalyptus Cloud, and CloudStack including VPC, autoscaling, and the ability to list most entities., and Openstack clouds: Rackspace, HP Cloud, and CloudFoundry Open Platform.
WaldScan is a PHP class which recursively scans a given directory for a list of selected file types. It has many uses for any Web page which serves files over HTTP/HTTPS, for a CLI program which does batch processing of files, or in cron jobs for caching file data for faster access.
KeyBox provides a way to manage OpenSSH v2 public keys, and can start a Web-based SSH terminal to execute commands and scripts on multiple SSH sessions simultaneously. The authorized_keys file is generated and distributed based on relationships maintained in the application. This allows for centralized management to help prevent public key sprawl. Also, composite terminals or scripts can be created so that commands can be shared across SSH sessions.
Higgs.IO is a high performance, message oriented network library built for realtime systems. It provides a core extensible framework and libraries built on top of the core. Libraries include a WebSocket server, an HTTP server and client, and Boson, a custom serialization and RMI library.
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).
JasperStarter is a commandline launcher and batch compiler for JasperReports. It can run any JasperReport that needs a JDBC data source or empty data source, use any database for which a JDBC driver is available, execute reports that need runtime parameters, print directly to the system default or a given printer, optionally show a printer dialog to choose a printer, optionally show a print preview, export to file in the PDF, RTF, .docx, .odt, and HTML formats, export multiple formats in one commanding call, print and export in one commanding call, and integrate in non-Java applications (for example PHP, Python) A binary executable is available for Windows. The string, int, and date parameter types are supported.
