Software DNA

You can think of phext as though it were a 'Software DNA' sequence! Recommended phext file size limits by team size:

1: 5 MB (100,000 LOC)
6: 20 MB (400,000 LOC)
10: 50 MB (1,000,000 LOC) - most balls of mud
1,000: 150 MB (3 million LOC) - Linux 2.4
10,000: 3 GB (50 million LOC) - Windows XP
25,000: 100 GB (2 billion LOC) - Google

Below are a selection of projects with large developer communities.
One human can generate about 60 MB of source per year with effort.
Successful projects will leverage this into abstractions.
