🐛 SPOT THE BUG 🐛

This code logs impressions for list items. But with Compose's new prefetching APIs, there's a subtle bug lurking.

If you look at what Compose's Dialog does, it respects the window animations and animates the Dialog out when it is removed from composition. So the Scene leaves composition, but the Dialog still animates.

Compose's Popup though? Just removes the window immediately: cs.android.com/androidx/pla...

I'm guessing it should be bearable esp. if you don't need to run a lot of services (although not so sure if on windows). But i suspect it'd take a bit of setup to spawn up and tear down multiple collection of containers in parallel. Perhaps docker compose's `project` flag should help there.

Oh yea, exactly. So I really need to give a heads-up somewhere, "You don't need to fix every unstable to stable" with Ben Trengrove's blog post. Still, it could be fun to use it as a tool for learning and exploring Compose’s stability system.

Uris coming from the system picker are mostly `content` schema Uris, so I can't just call `toFile` on them.

Conveniently, Compose's Font factories have a variant that takes a `ParcelFileDescriptor`, which can be obtained using `ContentResolver.openFileDescriptor(Uri)`.

Just got out of @zsmb.co Droidcon talk on Compose's Hot Reload, and I'm really impressed.

It now looks and feels like a solid product. Also, super interesting to see some of the work that happens under the hood to make it seamless.

Shows a lot of the platform's commitment to DEVEX.

💡 Why This Matters

These updates aren’t just incremental — they’re about closing the gap between Compose’s flexibility and production-scale needs.

If you’re migrating from Views, working on performance-critical features, or just want richer UI control — this release is worth diving into.

Tried Compose’s Busan Sea Salted Cream Latte the other day. There’s a pastel blue layer at the bottom, and together with the coffee and cream foam layers, it’s supposed to resemble the Busan coastline?🤍 Opted for 50% sugar, so it’s a little bitter, but I kind of like it like that🥤

I wrote this story back in 2014. For years it was lost in Compose’s archives. Really happy to see it’s back.

🚀 New release of Zimly is out — now with improved screen reader support!

Two takeaways:

- Jetpack Compose’s accessibility support is really solid.

- As a product engineer, obsess over UX — a bad experience feels so much worse when a computer voice yells it at you.

💡 That extra polish matters […]

I overhauled Compose's onboarding. Why?

Compose's conversion is terrible. People sign up, click around for 30 seconds, then disappear never to be seen again

Getting onboarding right for dev tools is hard. Users have to figure out how to integrate your tool into their stack before getting any value

This approach is what powers Compose’s fine grained invalidation and deterministic recomposition, while allowing state to be shared safely across threads.

Compose’s snapshot system implements a variation of the MCC (Multi-Version Concurrency Control) model. Just like databases.

Every state read in Compose happens in a consistent, point-in-time snapshot, and mutations don’t affect existing reads.

How does Compose know exactly what to update and when? 🔄

This chapter is a deep dive into the runtime: slot tables, composers, recompose scopes, and the entire in-memory engine behind Compose’s reactivity.

📣 @docker.com Compose v2.35.0 is out! 🎉
This release introduces a new type of service which enable extending Compose’s behavior through a plugin system.
The very first supported plugin is none other than Docker Model Runner!

however material has 2 big issues:

- by default its elevation algorithm is too aggressive, making it too light and gray for small elevation values (at least in Compose's implementation)

- it uses physical shadows with a single light source on the top, which sucks compared to a regular box shadow
