Comment 25,000 lines of code (Score 4, Insightful) 59
It might take one person one year to write 25k lines. How does a person get their head around that in 15 hours? One little "why on earth is this here" question can generate an hour or more in research with product managers, asking developers, reading 1000's of pages of documentation.... If it is fintech quant code, good luck with finding a quick explanation.
