Scripting your servers @coldclimate CANDDi.com
Put your pens down @coldclimate CANDDi.com
There once was a man... @coldclimate CANDDi.com
And then there was a document... @coldclimate CANDDi.com
Which became a wiki... @coldclimate CANDDi.com
Which finally because a script @coldclimate CANDDi.com
Which mostly worked... @coldclimate CANDDi.com
And then the madness had to stop @coldclimate CANDDi.com
You wouldn’t treat code like this (hopefully) @coldclimate CANDDi.com
Man => Document => Wiki => Script => Images @coldclimate

Man => Document Removing the bus factor “The man we
can’t fire” @coldclimate CANDDi.com
Document => Wiki The fucker *might* stay up to date

Wiki => Script Because script in documentation is stupid @coldclimate
