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.

I wrote a blog post that's really just an excuse to trick you into watching @worrydream.com's Inventing on Principle talk
The pursuit of fast feedback loops in Android development
There's something magical about having a direct connection to what we're building

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.
Two Kotlin functions that take 2 float parameters a and b. Each function returns a divided by b if b is not 0, or a constant called DefaultValue otherwise. The first function does so using takeIf, let, and the "elvis" operator. The second function uses a simple if/else statement.

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

Big changes coming to the Fragmented 🎙️

We’re moving from Wordpress → a leaner, simpler website. Long overdue and shipping in the next few days!

We also recorded our SemiQuincentennial (that's #250) episode with some very very big announcements.
