Ok cool, that's what I thought

I'm always surprised by how many people don't know about the Kotlin Slack community. It's a fantastic place to discuss issues with others, with dedicated channels for almost any Kotlin topic, and lots of JetBrains people monitoring them too.

So glad this is finally out! androidx.webgpu brings the WebGPU API to Android developers. Having access to a modern GPU API in Kotlin without dealing with the OpenGL legacy nor the complexity of Vulkan is exciting!

Nit: this affects only instrumentation tests, right? Or is there a similar issue with the --tests option for "./gradlew test" and others?

If they ever get around to building this thing, it should be bulldozed on Day 1 of a new administration. No messing around, no hemming and hawing about procedure or costs. Order heavy equipment in and start knocking it down immediately, as surely as an overthrown tyrant's statues would be torn down.

Jesse and Jake were my CN Tower. I only worked with them occasionally, but I always felt reassured just knowing they were around if I needed help. I'm mad our company lost both of them in the same week, and I'm afraid the entire Android OSS community will feel the ripple effect in the days to come.

Perfetto performance traces can be very intimidating. A talk by perf wizard @rahulrav.com makes it a tiny bit less scary.

The joy of doing it right: lessons from 50 billion downloads In this episode of Distributed, host Jack Hannah talks with Jesse Wilson, a longtime open-source contributor and Cash App engineer, whose work underpins much of the Java and Android ecosystem.

I talked to Jack from @tuple.app about my love of pair programming, and other things

That's pretty cool, maps.google.com seems to be using Filament now. I found its symbols in the WASM file used by the site.

Cash Android Moves to Metro The Cash Android team have completed the migration to Metro.

Cash Android has recently switched to Metro, a new, fast dependency injection framework built for K2. That was a fun project and we're really happy with the results! Sharing details on how we approached the migration to help teams adopt Metro: code.cash.app/cash-android...

So upset for Vlad, he willed that double down the left field line and got left on base 90 feet away 😭

Pinch hit for Kirk? Yamamoto should be the MVP. Impressive. He's like the Japanese Pedro.

I just discovered the WindowInspector.addGlobalWindowViewsListener() API in Android version 36.1 #AndroidDev

Happy to see a request for a new API land!

(I officially asked in 2023 & unofficially for many years before issuetracker.google.com/issues/29031...)

The latest Oxide & Friends covered the benefits of code that splits making vs. executing plans.

I love that pattern so much! Last year I wrote about how I use it.

Oura is the best. Ein prosit! 🍻

Okio 3.16 is faster if you have hundreds of threads 🚂

Today I was facing a gnarly somewhat mechanical migration and figured maybe I should try this AI thing.

First stab seemed ok, but many unrelated changes. So I said: revert, try again with no unrelated change.

Here's what the LLM responded:

"I micts\adelphia αsask齿ormaliy ibrahim郭 kepαt debug"

We conflate 2 different things when we talk about "velocity"

- External velocity: how fast we ship features
- Internal velocity: how fast we make code changes

They're connected but different.

Re-introducing Paparazzi’s Accessibility Snapshots Overview

PROGRAMMER: I've saved so much time!

NARRATOR: They did not save any time whatsoever. In fact, they spent as much time as they claimed to have saved. Again.

OkHttp 5.0 has a stable API. 🗿

I am surrounded by people who are outsourcing their own thinking to ChatGPT and they are quickly and obviously becoming dependent on it for even the most banal tasks. Once again, the "figuring it out" is the important part. Yes, you can use a crane to lift weights but you will not get stronger

is it using Volley and Fragments??

Knowing how Compose injects the Composer, wraps groups, and tracks remember scopes gives you full control over recomposition.
It is the difference between hoping your code is efficient and knowing it is.

That is the value of understanding internals.
