Finally have been trying out https://github.com/boyter/scc for counting (unique) lines of code, comments, DRYness and complexity and getting a better and more aggregated overview of the scale of my https://thi.ng/umbrella monorepo. SCC is really much better and faster than what I've been using previously (cloc) and also provides more meaningful results, including COCOMO project stats.
So selected current data points for this mega repo (incl. 214 projects and 185 example projects):
Estimated Cost to Develop (organic) $10,032,312
Estimated Schedule Effort (organic) 33.03 months
Estimated People Required (organic) 26.98
(This is equivalent of 74 years for one person and an assumed salary of $56k/year... Considering the repo in this form is only 8+ years old, that literally makes me a 9.25x developer 🙃)
