Synchronizes arbritary directories (on drives) outside the dropbox-directory with Dropbox, on the base of Include/Exclude/Include rules. Can also be used inside domains where the normal Dropbox sync is not allowed by the firewall. PyDropSync is tested on Win-XP and Win-7.

A simple python based tool for toggling the state of SSH Server in Debian systems featuring a small GTK2-GUI.

Designing network protocols by hand is a costly and sometimes troublesome work. This C# library implements a generic network protocol that transports the events object creation, object destruction and the change of a property of one of those objects. It also has facilities to observe the objects for property changes. In sum, the properties of objects that are taken care of by the library are automatically kept in sync. The only requirement to the objects is that they notify the modification of their properties, similiar to what WPF requires from a (typical) view model.

Save is a lightweight framework for creating high availability systems based on Mon with extensions for authenticated heartbeats and IP address takeover. Save also provides validation, synchronization, and archival of configuration and other files.

SynchedIn is a portable utility created to enforce realtime or latent synchronization of data (generally files) between different data storage sources. You can create as many synch configs as you please. Each synch config specifies a number of data sources, a number of schedulers. Each scheduler determines when the data sources must be checked for synchronization. Each data storage source represents a hierarchical (file system ...) or other type of data storage medium. These include hard drive, removable media, sequential devices, online storage services. Perhaps the most distinguishing quality of this utility is POP3 and IMAP storage providers which enable storage of files in a mail server, such as gmail or yahoo, in so much the same way as an online storage service (google drive, drop box ...). Storage providers could be configured for encrypted storage and specification as to what part of the underlying medium the provider represents. Components: GUI+CLI+Daemon+ConfigStorage

Up the Sync is a basic Google docs synchronizing program written in Java. It auto-syncs every 5 minutes by default, and can run quietly in the system tray. If the user updates a document on their computer the Google docs version is also updated.
