This is just a personal anecdote but probably worth noting for job hunters and learners:
I've been asked 3 times just in the past week (!) by hiring managers for native Android developers!
If you're deciding what you want to pick up/hone, that seems to be in pretty high demand right now.

Is there a reference implementation of this? Would be neat to see
Tinkering around for fun, a computer science undergrad realized that he had invented a new kind of hash table, one that worked faster than expected—taking less time and fewer steps to find specific elements.
Undergraduate Disproves 40-Year-Old Conjecture, Invents New Kind of Hash Table
A young computer scientist and two colleagues show that searches within data structures called hash tables can be much faster than previously deemed possible.

Interesting - $7-8 for only no ads on YouTube feels pretty compelling imo. I’m sure they’re doing a ton of testing on it to make sure it doesn’t cannibalize too many sales of the full Premium membership

I want to like YouTube Music, but it feels like an afterthought of a product from Google. If they ever unbundled it from YouTube Premium I think it’d be in trouble.

Getting feedback loops below the "I can alt tab while this builds" threshold is so critical for me. A 1 minute build is basically the same as a 3 minute build if I lose focus.

I love Kotlin but please don't abuse its features. I regularly see code like in the first function when you can instead write a simple if statement: it's shorter, easier to read, and doesn't allocate an object!
Thankfully both functions compile to the same assembly when R8 is turned on.

Let's look at Bluesky performance on Android!
I managed to build a release build of the app and ran some traces, let's see what we can find...
I have ~hour, will add to this thread as I investigate

I don’t think so. It’s more likely a symptom of an overly complex view hierarchy
