As an experiment I am rewriting my Expo app to Swift and adding a macOS desktop version. Turns out the biggest performance problem is... the macOS itself. Often takes couple hundred ms to show a popup and there's little there that can be done if I want the app to stay 'native'.

It’s a weird feeling to see gaming parts market totally frozen in time. My GPU costs ~the same as it did in 2022. Buying PS5 is still a valid choice. Something unthinkable in 2010s.

I have an app using Expo UI. Since it’s a popular thing recently I ported it to plain UIKit. Looks like there are things we could make lighter! Funny thing is I couldn’t tell apart the apps because obviously it doesn’t get any more native than SwiftUI in Expo.

We have built 10 different AI products at PostHog like PostHog AI, our Wizard, Replay Vision, Scouts, and more. Combined, they are used by nearly 100k people every month. Along the way, we’ve learned a lot about building them, what works, and what doesn’t. Here are the 38 most

Opus 5.5 can get so much done within the weekly limit but sometimes I am impressed how fast a dozen of parallel background agents can quickly kill a session limit
