Listening to my server
The first server I connected to the Internet sat on the floor of my office, close enough so I could hear -- and feel -- its response to heavy load. It seems weird to admit that I relied on those sensory cues, but I've talked to enough system administrators to know I'm not alone. The sounds of a working machine enable the pattern recognition engine in your brain to create a baseline -- and to detect deviations from it -- in ways that are effortless, automatic, and incredibly efficient.
