I want to share with you this super method of productivity estimation of software development.
Anyone heard about staff folding in ASP .NET MVC? I want to share with you this method which allows to estimate an effort in adequate manner.
This video has last slide about it.
Entropy!
It is often said that entropy is an expression of the disorder, or randomness of a system, or of our lack of information about it.Compression shows well how much unique information (with best randomness, entropy->1) is in a file. So compressed code size shows best who put more effort.
You know what, almost every SCM already does the compression! You only need to see a compressed object file size to gather needed information.
So the measure of value is bytes of compressed diffs.
