Or, strange as it may seem, they learn how to write software from a four-year college degree. And colleges are notoriously bad at teaching so much as source control, let alone what source control options are there, how to use a bug tracker, etc. (Which makes sense, because you don&#x27;t strictly need source control if you aren&#x27;t collaborating heavily, and you don&#x27;t need a bug tracker if you have a single development week-by-week.)
