Cuttlefish is a simple tool, which realises reflexes on your computer by executing actions when specific events are triggered. You can configure the tool in such way that cuttlefish can for example change your default printer according to the currently connected wireless network. You can also lock/unlock your computer, when a specific USB device is dis/reconnected.

Install:
The cuttlefish is available in Ubuntu 12.04 Precise’s repository. If you want to install this app on Ubuntu 14.04 or Ubuntu 13.10, besides building from source, you can use my PPA which contains the latest build released in December 2013.
