SNeBU (Simple Network Backup Utility) is a backup system that supports incremental snapshot-style backups to disk-based storage. The project has been rewritten in C, and stores its backup catalog in an SQLite database. It features file level deduplication (including across multiple clients), compressed storage, incremental-forever snapshot style backups, simple setup, and utilizes standard TAR format. The client side consists of a simple shell script, which can be easily installed and adapted as needed. The server side is a single binary plus a config file, which can sit on a remote server and be accessed over SSH.
Rumble is a mail server suite for SMTP (ESMTPSA), HTTP, POP3, and IMAP4v1 with an extensive C/C++ and Lua API for scripting. It comes with support for SSL/TLS, SQLite, and MySQL and has a Web-based administration and Web mail feature. Additional included modules feature greylisting, DNS blacklisting, SpamAssassin support, and dynamic performance scaling as well as a multithreaded structure that allows for clustering of multiple servers for one or all domains. With the Lua API you can create your own new server mailing lists, CRM software, e-marketing, and other extensions within minutes.
Vocab Builder is a collection of two separate programs. The client is the testing application that uses a drill-style method of building your vocabulary in a foreign language, similar to using flash-cards. The editor allows you to create a new, or modify an existing, database for your own personal use. Since the design of the project allows a user to create their own databases/tests, they can not only focus on the words they want/need to learn, but also are not restricted by availability of choice. No more are you restricted by only the databases available to you. Many language teaching applications only allow you to learn the languages they've supplied you. Most North American-based programs cater to English speaking users and only give you a selection of other languages to choose from. Not only can Vocab Builder use any language combination of Native and Secondary languages but it's also open-ended. You can share your tests with others. You can expand the database of words in any direction you want. Word lists are meant to be broken down into categories like colors, sizes, numbers, etc.
Winnow efficiently trains and operates any number of unique Bayesian (Naive Bayes) classifiers on large sets of content. It has very high performance and works with very small training and unbalanced training sets. It has been used to power an innovative Web feed reader that uses smart tags, which learn and find the content you want to see, from more sources than you can follow with traditional feed readers. It works particularly well with Ruby and Ruby on Rails.
SwarmTv is a command line broad-catching program that downloads selected torrents/NZB's from an RSS or Twitter feed and puts them in a directory for your torrent program to download. The torrents to download are selected using filters that look at the name, size, and episode/season of the torrent. A mechanism is in place to prevent double downloads. Swarmtv can even send an email when a new episode is found.
