What is evil? It's not some force, roaming the land. It is a dark spot inside each of us. It's an absence of love.

I ordered the new backup server on October 27.
Initial setup gave app crashes intermittently, so was not ready to make it live yet.
I ran BOINC on it for a day, and at one point, all tasks died at once.

Syslog showed EDAC errors starting 11 days after I got the system, calling out

Josh 201604 KWP
joshdavis
This is a SWAG for calories burned cycling 12-15mph:

* Divide your feet climbed by 10.
* Divide again by your average MPH.
* Add that to your total miles.
* Multiply the new number by the weight in pounds of you, your bike, and everything you're carrying.
* Multiply the new number by 0.105
