Is it bad practice that a controller calls a repository instead of a service?

Is it bad practice that a controller calls a repository instead of a service? To explain more: I figure out that in good design controllers call services and services use repositories. But sometimes in controller I don't have/need any logic and just…

Short circuit evaluation, is it bad practice?

Something that I've known for a while but never considered is that in most languages it is possible to give priority to operators in an if statement based on their order. I often use this as a way to prevent null reference exceptions, e.g.: if…

TDD Red-Green-Refactor and if/how to test methods that become private

Using multiple Git repositories instead of a single one containing many apps from different teams?

I am migrating a 10-years-old big CVS repository to Git. It seemed obvious to split this multiple-projects repository into several Git ones. But the decision-makers are used to CVS, therefore their point of view is influenced by CVS philosophy. To…
