Due to C portability, OpenOffice.org's usual middleware, Universal Network Objects (UNO), could not be designed object oriented. With NOA-libre you can still access UNO, but also the NOA-libre object oriented layer atop UNO. Being based on UNO, NOA-libre is network aware, meaning that you can use it to have your local office installation execute some commands, or an OpenOffice.org installation anywhere on the world, provided you have a appropriate network connection and privileges. With NOA-libre, you can: embed OpenOffice.org windows in your Java applications or applets; remote control OpenOffice.org windows on your desktop, over the network, or "headless", i.e. only functional without visible output; and/or extend OpenOffice.org by writing Java plugins. NOA-libre is compatible with OpenOffice.org and LibreOffice, easier to deploy than the usual UNO-only Java applications, and allows you to interact with various OpenOffice.org components (but is by far most commonly used with Writer and Calc).
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.
Xtreme Download Manager is a advanced and powerful tool to increase download speed up to 500%, resume broken/dead downloads, capture FLV videos from any site, and schedule downloads. It uses a sophisticated dynamic segmentation algorithm, data compression, and connection reuse to speed up the download process. It supports HTTP, HTTPS, and FTP protocols, firewalls, proxy servers, file redirects, cookies, authorization, etc. It seamlessly integrates with Firefox on any operating system. It also integrates with any other browser to handle downloads automatically using advanced browser integration. It is entirely written in Java, so it runs on any operating system without even being installed.
BAD (BAckup Daemon) "watches" a directory and copies any files or directories moved/copied into it to another "backup" directory automatically using inotify. It will automatically generates hashes for files using the md5 hashing algorithm, and stores them in a file for quick and easy integrity checking. It will log (mostly) everything it's doing, and makes it very convenient to grep for certain messages using multiple logging levels which the user can set to get the desired output. It has its own built-in uninstaller which will delete any and all files it has created (besides the user's watch and backup directories).
