How many lines of code (LOC) does it take to be considered a large project? How about for just one person writing it?
I know this metric is questionable, but there is a significant difference, for a single developer, between 1k and 10k LOC. I typically use space for readability, especially for SQL statements, and I try to reduce the amount of LOC for maintenance purpose to follow as many best practice as i can.
For example, I created a unified diff of the code I modified today, and it was over 1k LOC (including comments and blank lines). Is "modified LOC" a better metric? I have ~2k LOC, so it's surprising I modified 1k. I guess rewriting counts as both a deletion and addition which doubles the stats.
A slightly less useless metric - time of compilation.
If your project takes more than... say, 30 minutes to compile, it's large :)
