Talk: Deriving derived state: derivedStateOf explained

This is a follow-up to my last snapshots talk, Opening the Shutter on Snapshots, and a companion to my article How derivedStateOf works: a deep d(er)ive. I've also written a bunch of articles on Compose state, check them out here. Slides: Deriving derived state: derivedStateOf explained

How derivedStateOf works: a deep d(er)ive

Compose's snapshot system is really neat, as I've talked and written about before. Once you know how it works, you can do some cool tricks with it, and derivedStateOf is a rich example of this. I recently gave a talk focused more on explaining the algorithms

Compose State Series

Restartable functions from first principles

Often when thinking about Jetpack Compose state, we think in terms of what code will be re-executed when that state changes. We call functions that get re-executed like this “restartable functions”. Composable functions are generally restartable, but some other functions are restartable too, and you can make your own. 📖This

Talk: Opening the shutter on snapshots

I had so much fun writing about Compose's state system that I decided to give a talk about how the snapshot system's algorithm works. I gave this talk initially at droidcon NYC in 2022, then again the next year at droidcon SF.

This year, Workflows meet

Compose State Series

Implementing snapshot-aware data structures

Up to this point in this blog series, I've discussed how to use Compose's snapshot state system, some advantages of how it's designed, and the occasional best practice. But I haven't talked about where the rubber meets the road: how does something

Compose Hackathon: Day… the rest

I meant to write this on Friday, but got caught up trying to gather some last bits of data after my dev environment fell over and decided to stop running benchmarks altogether. Since Wednesday… In the last post, I left off having built the piece table I initially meant to.

Compose Hackathon: Day 2.5

Well, so much for blogging every day. Better late than never, right? Anyway, I have a good excuse: I’ve been super busy writing code and tests, and it’s not going terribly. I'm calling this day 2.5 since I was up a large part of the

Compose Hackathon: Day 1

Introduction This week the Jetpack Compose team is doing a hackweek. I am using it as an excuse to try building something I've been thinking about basically since I joined the team. I'm not sure if it will work, or if it will be fast enough
