You might be surprised how little power it’s sipping when sitting idle. Unnecessary disk accesses might be the biggest power use in those hours, but that’s more likely to cost you due to wear and tear and eventual replacement of the drive.
I recommend buying a Kill-a-watt and monitoring your power consumption on the server for a week or two. Then do some math to see how much it’s actually costing your energy bill. If it’s actually considerable, then try using tools like powertop to see if you can determine what’s generating all the activity.




Team? Win? The original Button didn’t have teams or winning. That’s not as good because then there are a chunk of people who are actively incentivized not to press it.
The Button was interesting because teams/button ideologies formed organically.
