About this ranking

r/datascience's top recommendation is hands-on-machine-learning with 36 mentions — more than twice the count of anything else on the list, and nearly triple what r/MachineLearning managed for the same book (14). The second slot goes to trustworthy-online-controlled-experiments at 20 mentions, a title that barely registers on any other programming sub, signaling a distinctive focus on experimentation and causal inference over pure ML theory. designing-data-intensive-applications appears at 14 mentions, but compare that to r/ExperiencedDevs where it sits at 247 — here it's a supporting reference, not a cornerstone. The general-purpose software engineering titles (clean-code, the-pragmatic-programmer, fluent-python) fill out the list at single-digit or low-double-digit counts, reflecting a community that treats software craft as a secondary concern behind applied modeling and data methodology.
