"Refactoring is a natural part of coding. You don't explain to management why you need to write while and for loops" -- sourceSince I tweeted this phrase in quotes ("), we can assume it is not an original work of mine. I guess I heard it in some presentation, probably of Uncle Bob. What kept me from including the source on Twitter was the 140 character limit.
My Master's Degree specialization is in Data Engineering, and finding quotes in videos is one of the common task for multimedia search engines we study and research on. Maybe one day we will be able to find this phrase's source video with a single click, in the same way as we google a term today.
