Slot table in Jetpack Compose uses a doubling strategy to grow 🌱 It starts as empty. When 1st group is added, it grows its capacity to 32 slots, all the new free space goes to the “gap” 🧵

Someone asked about the difference between running an effect using SideEffect vs writing it directly in the Composable. It’s well explained here in the official docs. If a composition throws, effects related to it should not run either. developer.android.com/develop/ui/c...

You’re never too old for something. Don’t let people make you believe that. There is not an age deadline to achieve things in life. Many people succeeded on their 60s, some even later. You’re right where you need to be.

Please don’t call composable functions “view” or “views”, it’s so confusing. You can say composables, or just call it UI.

Visualising yourself overcoming any complicated task before doing it is the actual game changer. That is literally what makes things happen. That’s how I landed all my jobs in tech, and also how I achieved other non work related goals in my life.

I decided to write the Jetpack Compose internals book because going deeper made me deeply understand the View system back then, which helped me so much in my professional work. I knew same would apply to Compose.

Nobody remembers much about the work you do, your merits. This is the hard truth, so always write down everything. You’ll need it especially during eval season, or whenever you want to ask for a role change / raise.

Composable functions must be as dumb as possible, like UI state renderers. Pass them only the state they need to render. Don’t inject dependencies on them, do that on ViewModels, resolve all the state before collecting. Make them easier to reuse, configure for previews, and to test.

There is no better way to learn how to explain code in simple and understandable words than having to teach someone. Many devs are amazing engineers but they are not good when speaking about code, which is especially important.

I officially dropped from the GDE program yesterday, but I’ve been kinda out of it since long ago. I’m thankful for my time as GDE, but the ways I contribute today are more business related and it’s not fair to keep the role. This does not mean I’ll not be around though!

Found this gem from that lying sack of shit Musk buried in my bookmarks. He absolutely did NOT give 3 months severance (also not 50% more than "legally required"). He paid out the bare minimum required by federal law and he's being litigated for the rest. I know this for a fact because I lived it.

Macrobenchmarks can be the most efficient tool to measure Compose migrations to move forward confidently. We use them heavily at Disney for several things, including to ensure frame times stay good when migrating isolated components. Measuring scoped migrations under realistic context is priceless 🎄

It’s really great to see this progress on Compose hot reload. If the team is able to overcome the challenges of incremental builds and keep build times low, it’ll be a total game changer. Wondering how it will behave in real life big projects.

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.

One of the hardest things to explain from Compose is class stability. Hopefully we can become fully agnostic of it eventually. Strong skipping is definitely helping us to get there, but I still find myself having to think about class stability every now and then.

Completely agree, and it should be part of the design specs too. UX is UX.

Just this. Don’t let imposter syndrome make you think you need to do any of those things. I’ve worked with so many great engineers in incredible teams from great companies that didn’t do any of that.
