Most of the high visibility “tech bros” aren’t technical. They are finance bros who invest in tech.

I often use imagemagick (cli) for cropping, rotating, resizing, etc.

Sometimes after upgrades, even minor ones, I find it useful to run analyze on all of the tables. I usually do analyze verbose; so I can see which tables are getting analyzed. This will assess every table so the query planner can make better decisions about how to resolve queries. If the query planner is making bad decisions I/O and CPU will be high and query performance will be poor.
