We have a slight air conditioning problem at work; they ice up, overheat, or whatever, "trip out" and need to be switched off for two minutes to reset them. This is annoying when it happens to your office, but slightly scary when it happens to your machine room.
So, temperature monitors, so we can at least notice it happening. Mark pointed me at this digital weather station with linux support, but it seems like slight overkill (I suppose we could stick the anemometer in the air vent). Some googling turned up DigiTemp, which looks cheaper and promising, and PCMeasure which would look promising except that it appears to be German and expensive. However, it had a link to temperatures.com, which appears to be a community about temperature measuring. I guess people will obsess about anything.
