This is flat out not true. FB doesn't employ 10s of thousands of human moderators.
According to a 3-month old article, $FB supposedly employs 7,500 moderators [0], though it's unclear what constitutes "employment" in this case. Probably a salary of less than $5k/yr. Are there really thouhsands of content moderators pulling up to FBHQ in Menlo Park 5 days a week? I don't think so, no.
"By the end of 2018, in response to criticism of the prevalence of violent and exploitative content on the social network, Facebook had more than 30,000 employees working on safety and security — about half of whom were content moderators." [0]
That number has only increased in recent months and will likely continue to increase in the near future. Not all of them are designated content moderators, it's true, so technically they likely only employ one or two "10s of thousands", but I'm mainly addressing the misconception in the thread that Facebook is "doing nothing." That's a significant amount of moderators. Is it enough? No, but to claim or pretend that they aren't actively doing anything is facetious and something I've been seeing more and more of on HN lately.
The creator, Solomon Hykes, rubbed a lot of people the wrong way with his arrogance and narcissism, not to mention poor netiquette.
Docker is also a huge layer cake of code, not elegant or beautiful by any stretch. At this point there is enough lipstick on the pig that it more or less works okay in general, though frequently still remains the source of many a headache.
A very astute question. Yes, as much effort goes into the design of the underside as does the shiny side.
The most recent article I found via a quick G search is from 2013. For sure the rules have changed since then, but it's still a fair benchmark to illustrate the complexity of overall design with regards to the aero.
There isn't that much teams can do on the underside of the car. A lot of effort goes into preventing air from "leaking" under the car in the first place.
While you don't see the underside of the car much (for obvious reasons), the occasional roll-over crash (or crane lift after a 'regular' crash) gives us a glimpse from time to time. Check out Nico Hulkenberg's crash at Abu Dhabi pay year for a good example.
