If the machines were awake for 12 extra hours a day, and drew 100 watts, that's 0.1kW * 5000machines * 12hours = 6000kWh per day.

Where I live, electricity costs about 20 cents per kWh. 0.2dollars * 6000kWh * 365days * 9years = $3.94 million.

reminds me a lot of an old multiplayer network game called "liquid war"

Sorry, I should have worded that better. I know what the message means, but what do you make of the fact that it found & repaired corrupt data? If I understand right (and correct me if I'm wrong), corrupt data should only occur if some bit of hardware is failing or possibly after improper shutdown. Am I wrong? Is it no big deal to see scrubs repairing data?

What does "scrub repaired 1.58M in 201h47m with 0 errors on Fri Feb 21 13:37:24 2014" mean?

I have a much smaller zfs setup at home, as well as a few at work, and I would be super concerned if the scrubs were repairing data. Am I overreacting?

The parts that generate the lion's share of heat in an LED bulb are tiny tiny tiny, and so they can get very hot with much less energy. They generally have chunky heatsinks, but still you can only draw heat away from a point the size of a head of a pin so fast.

I like to use elements. Bonus if you're working with the first half of a /24, last octet = atomic weight. 10.0.0.1 = hydrogen, etc.

In your background image, the screws at the top are threaded anticlockwise, but have a clockwise rotation arrow. Vice versa for the screw at the bottom by the robot head.
