Babelj is a language server for Java. It allows programs written in practically any language to fully interact with Java. Client libraries currently exist for PHP3 and Java. Babelj can be used as an out of the box bridge between PHP and Java and adding support for new languages is a snap as well.
Magic Mirror Backup works by copying the files and folders on your computer to other computers within your office. In exchange, these other computers also copy their own files onto your computer. This sharing of backups has quite a few advantages not the least of which are that it is extremely convenient and cost effective. (This symbiotic mechanism for backing up data is often called peer to peer backup or p2p backup.) There is also an optional off-site component so that you can additionally backup to a remote server to protect against office-wide failures like fire, theft, or hurricanes.
