Remus provides transparent, comprehensive high availability to ordinary virtual machines running on the Xen virtual machine monitor. It does this by maintaining a completely up-to-date copy of a running VM on a backup server, which automatically activates if the primary server fails.
Starting with version 3.1, VirtualBox supports “teleporting” — that is, moving a virtual machine over a network from one VirtualBox host to another, while the virtual machine is running. This works regardless of the host operating system that is running on the hosts: you can teleport virtual machines between Solaris and Mac hosts, for example.
Think of BigCouch as a set of Erlang/OTP applications that allow you to create a cluster of CouchDBs that is distributed across many nodes/servers. Instead of one big honking CouchDB, the result is an elastic data store which is fully CouchDB API-compliant.

Hepburn Wind is building Australia’s first community-owned wind farm. Our two turbines on Leonards Hill, 10km south of Daylesford, Victoria, are expected to be operational in the first half of 2011. Expert analysis predicts that the wind farm will annually generate more power than used by the houses of Daylesford.
The Motoruino board is an Arduino compatible designed to make working with motors, servos and sensors easy. With an on-board L293D motor controller a pair of motors can be easily controlled. Also each pin is broken out to a 3 pin (pin, gnd, pwr) header meaning standard servo and 3 pin sensors can easily be attached.
