Senior ICs tend to commit relatively unfrequently compared to junior ICs who keep pumping tickets.

Not in my experience, as long as we are talking about ICs.

Or alternatively (assuming that's true) he fired the people who thought about what they commit and kept those whose commit logs look like: "push feature WiP", "fix", "more fixes", "push", "maybe this works?"...

Reportedly a portion of them were thinking so hard they did not commit anything at all.

Ironically, those may have been the staff with the most institutional knowledge. Seeing people argue, here of all places, that loc or commit frequency == institutional knowledge is … unexpected. New hires committing “whitespace cleanup” != institutional knowledge.

Someone had to actually write all that code and it inevitably shows up in the stats. People who work on the code most tend to know it the most. Although people in non-coding roles sometimes prefer to deny it.

Sure there had so be some frequent but low impact committers. But implying that people with lowest amount of code contribution must have more impact is ridiculous.

I mean, a staff engineer who stopped committing couple years ago? Yeah could be burnout, or could be some major contribution that's not in the stats. OTOH an IC on their second year in position who hadn't pushed a single line? Nah the institutional knowledge is safe without.

> From what we gathered on the kitchen side he fired the most infrequent committers. Which statistically speaking would not affect the institutional knowledge much.

This take is, quite bluntly, stupid and clueless. Do you think each commit reflects the volume of institutional knowledge of any individual? Unbelievable.

Twitter had thousands of coders, each certainly with varying cadence and style of committing. But variation goes only so much and taken in aggregate yes, the amount of commits/diff size is correlated to contributor prominence. It's kinda hilarious the "my -2000 lines" types deny the obvious.

Hey man, just wanted to let you know, I had to downvote a bunch of your comments in this thread, not because I disagree with you, but because your commenting style is unnecessarily hostile and abusive. You can politely disagree with someone without calling their take "stupid and clueless", or any of the other mean-spirited things you've said elsewhere in the thread.
