Nice. Found that one on HackerNews
The evolution of the Unix operating system is made available as a version-control repository, covering the period from its inception in 1972 as a five thousand line kernel, to 2015 as a widely-used 26 million line system.
The 1GB Unix history Git repository is made available for cloning on GitHub. Currently the repository contains 659 thousand commits and 2306 merges from about 850 contributors. The contributors include 23 from the Bell Labs staff, 158 from Berkeley’s Computer Systems Research Group (CSRG), and 660 from the FreeBSD Project.
from 5000 line to more than 26,000,000 lines. Is that accurate?
Can’t speak to the 26,000,000, but the 5000 is probably right. The PDP-8 was I think either 8 or 16K of memory.
