It used to be very popular in many software organizations to measure programmer productivity in LOCs - lines of code written. Sounds reasonable - after all, if your programmers are working away and the code base is getting bigger and bigger, then something good must be happening. You do still sometimes see companies bragging about how many kLOCs their latest product is.
Over the last two days, I'm on a net LOCs written of -2000. Over the last 3 weeks I've discarded around 500k of source code, which is god knows how many. It does lots more stuff and it's got less bugs. Less code is, in almost every case, more.
