My training material: don't call your variables x,y and z: no one will be able to work out what they're for.
My students: here are variables a, b and c.
@christianp "don't call your variables x,y and z" - ideally, this is nice. In practice, this can complicate comparing what you have against what's in the book/paper/whatever you're referencing. ;)
@tpfto not referencing a paper, coding e-assessment questions
@christianp Oh, that's much easier (for the kids) then. Still, they might get shocked later...
