A roll of plastic and three hours later, we could completely turn off one of the cooling units, which had been on full blast for years. The servers now breath in only cold air from the cooling units, and the cooling units only warm air from the servers.
Frankly, I am shocked and appalled that they found the blueprints to TIFI's server room.
3 U Penn students developed the µWave (microwave, get it?), an Arduino based kitchen hack that plays Youtube videos while you wait for noms. Once you set the cooking time the program goes to Youtube and finds a highly-rated video for the exact length. Read more about it at the project's website.
