Only if they are well-known in the language you’re using or domain you’re writing for. x and y are fine for coordinates. i and j are fine for loop indices. But abbreviating things unnecessarily is bad IMO. s = GetSession() is too terse, for example.

No, I mean single-letter vars are standard in physics and math, but reusing vars is not acceptable. Obviously they're not good practice except in the scenarios you describe, but mathies gonna math.
