I think if I can expect my mom to know what it is, I shouldn’t have to define it in articles any more.
So TLS and URL get a pass, BSD’s and MCP need to be defined at least once.
Your mom knows what TLS is? I'm not even sure that more than 75% of programmers do.
If programmers had a character sheet it would state they have a -50% penalty to any security concepts.
Does your mom really know what TLS means? I would guess that even "tech savvy" members of the general public don't.
