'ayeka' - our home server
A Linksys NSLU2 network-attached storage device, with a 320Gb Seagate USB hard drive attached. The 'slug' (as the NSLU2 is affectionately known amongst hobbyists) has the 'Unslung' alternative firmware loaded, which allows for additional software to be installed. It now acts as our intranet and e-mail server, and I'm working on a few other applications for it - not bad for a machine the height of a Coke can...
(Update (2007/01/06): I've now moved 'ayeka' to the rack next to the trolley where this photo was taken, and added a Pertelian USB LCD display for system stats, etc. See other 'nslu2'-tagged photos in my photoset for views of the new setup.)
(Update: (2011/01/22): The "slug" has now been replaced by a Synology DS110j NAS device - see this photo for the new setup. In fact, the PC next to the "slug" in this photo is now out of action too - all change...)
