When, if ever, is “number of lines of code” a useful metric?

Question

Some people claim that code\'s worst enemy is its size, and I tend to agree. Yet every day you keep hearing things like

• I write blah lines of code in a day.

Answer 1

When the coder doesn't know you are counting lines of code, and so has no reason to deliberately add redundant code to game the system. And when everyone in the team has a similar coding style (so there is a known average "value" per line.) And only if you don't have a better measure available.
