One mistake we made in an old version of Dropbox was that directory moves looked cheap (drag a folder) but were expensive on the server (update metadata for every file in the tree).27 Jan 2025 19:58 +0000at://did:plc:ffcflssnm7643npbheh7j5vv/app.bsky.feed.post/3lgqq2neftc2fhttps://bsky.app/profile/jamescowling.dev/post/3lgj7r2xtis25Got to sit down with Professor @andypavlo.bsky.social on the latest @convex.dev Databased podcast for his 2024 databases year in review! https://www.youtube.com/watch?v=1B-MdlHat9c24 Jan 2025 20:18 +0000at://did:plc:ffcflssnm7643npbheh7j5vv/app.bsky.feed.post/3lgj7r2xtis25https://bsky.app/profile/jamescowling.dev/post/3lge5h7psls2xIf you want to get good building systems and databases you should go work for a bigger company or a startup with serious infra demands.
