I’ve been a fan of Apple since I got my first iPod Touch 2nd gen in 2009, but with their political actions I‘m strongly considering to not buy an iPhone again. As a tech person, it‘s sad to see that we‘ve basically got a US duopoly for mobile operating systems :(

PSA!
It's so easy to forget to handle websocket reconnects in LV, but if you're deploying regularly, your users are likely seeing A LOT of bugs coming from this.
Go to one of your pages, click around a bit, then run `liveSocket.socket.triggerChanError()`, and see what happens.

Break apart your features into full-stack slices
Our communication practices can be very disrupting. Remote work has taught me to be more considerate of how I communicate with others. We should treat other people's time as we like ours to be treated...

Postgres 18.0 was just released!
What does it mean for Oban? Glad you asked:
- Asynchronous I/O for improved scans
- Skip scans for multi-column B-Tree indexes
- Parallel builds of GIN indexes
- Improved vacuum strategy
- Many optimizer improvements
- Native UUIDv7 data type
