Nicholas Carr writes that corporate HR departments should kill companywide screensavers in effort to both protect the environment and free up compute cycles for things like curing cancer. Carr was talking to a pharmeceutical CIO about using grid computing technology to harness the PCs in the office for work on drug analysis. But:\n\nThe corporate communications department created an elaborate screensaver, complete with video clips featuring the CEO, to promulgate a "corporate values" program. Installed on all the company\u2019s PCs, the screensaver sucks up the processing cycles that might otherwise be put to a productive use \u2013 like finding a cure for cancer.\nCarr goes on to point out how much waste is generated by useless screen savers sucking up processing and electrical power. \n\nHopefully our HR department doesn't read this and get any "smart" ideas.
