The fundamental theorem of Agile Software Development

J.B. Rainsberger talks about the Fundamental Theorem of Agile Software Development. In his talk he refers to Fred Brooks Mythical Man Month(a must read!), accidental vs essential complexity, the cost of a feature, how to do estimations taking both types of complexity into account, reduce accidential complexity using test driven development, the formula cost=f(g(e),h(a))=g(e) + h(a) and why refactoring is necessary to make Agile development work and all of this in 7 minutes and 26 seconds(also the name of his talk).

A must watch!

A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try!

Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...
