Elon Musk tweeted an image on a whiteboard from a "Twitter HQ code review" that wrapped up early Saturday. The image has attracted nearly 12k upvotes and over 1,000 comments over at the subreddit r/ProgrammerHumor, under the title "Twitter for Dummies". The image itself is an architecture schematic, not code. I put it on a Miro Board and Luke Dubois and Mark Hansen helped annotate it.
