Questions tagged [internals]

The internals tag denotes questions about how things work, as opposed to how to accomplish something specific. Of course, how something works underneath will have practical implications, but internals questions aren't about how to do something; rather, how to understand something.

If you understand how a database or parser or version control system actually works, you'll be better at using it. Internals questions seek this kind of inside knowledge.
