Elon Musk published a 57-page white paper for the “Hyperloop,” shooting pods through low-pressure tubes at 700mph, then said he’s too busy to build it and someone else should. The audacity of publishing homework and assigning it to civilization. Engineers at lunch spent two hours debating thermal expansion joints. We ship a CRUD app.
Also: Jeff Bezos personally bought the Washington Post. Not Amazon, just Jeff, with his wallet, $250M. A newspaper. Everyone has a theory and all the theories are about data or ego or both.
Our client launch shipped. It mostly worked. One bug made every user’s avatar the dark face for about an hour, which the client’s employees have apparently declared the greatest day in company history.
TIL: caching is a lie you tell your database with consent. We added Redis this sprint. First it made everything fast, then it made everything wrong (stale cache after edits, my bad), then fast again. There are two hard problems in computer science and I have now personally met cache invalidation.
