So you think you have a big rat’s nest of cables under your desk? Here’s mine. What you’re seeing, besides the obvious PC, is a four-node Linux cluster. Each of the mysterious-looking black boxes stacked next to the PC contains two nodes; each node contains I can’t tell you and three fast Ethernet ports. All of those ports feed into the 16-port switch hiding in the background using the shortest cables I could find, and it’s still a horrible mess.

I’ve decided to call the nodes meatball, tomato, garlic and oregano.
