Happy Holidays friends! 🎁

For me holiday also came with a gift.. after 10 days of iteration I was able to build a basic app for my kiddo to practice math problems.

Reinventing the wheel is always fun! 🤓

Now I know what I would be doing this holiday season aside from spending time the the family! 🎁🎄

LLMs are surprisingly very good at providing estimate that I likely would give!

This is impressive! 🤓
Other changes include the usual bug fixes and improvements. Something I'm regularly excited by is how many people are contributing to Metro (11 in this release alone!)

JetBrains idea integration for both Copilot and Junie is subpar experience compared to CLI versions or VS Code.

I keep going back and forth with VS Code because of how well the integration works for Copilot.

You can't have everything, if you have it all! 🙃

I sure didn't expect myself to find on top here! 🫣

By no means I am a DI expert, and this is not a comprehensive search and analysis on GitHub.

However, I do love @zacsweers.dev's journey on Metro! 🚇

It's December 🎄 and year is almost over.

2025 has been the year of applied AI in life! It definitely has empowered me to do more! 💪🏽

Don't know what the future holds, however I hope that we find a way to lift everyone's lives for better! 🙏🏽

I randomly bumped into one of the talk and hear speaker mention two of the hardest challenge in software engineering:

1. Naming things
2. Cache invalidation

Couldn't agree more on these two! 😅

No Google, you didn't!!

Getting on the liquid glass band wagon for Google Play, really? 🤦🏽‍♂️

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.

Umm! I am confused! what are you saying copilot? Make up your mind! 🤖

Wow! another VS Code clone! 💻

Time for #GoogleAntigravity 🙃 (antigravity.google)

And time to checkout Gemini 3 Pro! ✨

Wow! this is huge undertaking! truly amazing feat! 🚀
Let's go Metro! 🚇

Testing out over half a dozen of simultaneous GitHub copilot agent to add unit test coverage.

Let's see how it goes! bracing for some tiny conflicts! 😅

I only got respect for Apple - being able to run chome, gradle, android studio with emulator on 8GB ram & fan-less laptop! few years ago, it would be a pipe dream!

This is fantastic and @zacsweers.dev deserves all the praise but it also is gonna give you a false idea of what Z is like as a maintainer and author, what the project is like, and how you might achieve something like this yourself
Hot take: Dependency Injection on Android just got a huge upgrade!!

Square just moved Anvil to maintenance mode to adopt Metro - a DI framework built by ONE PERSON that's 47-56% faster than Dagger+Anvil.

This is what "individual developers changing ecosystems" looks like 🧵

Whats the point of using fast UFS drives in phones if it can't deliver same throughput via USB-C connection? Why are we still using MTP on Android!!!

Waiting for 1 hour+ to transfer 20GB files from recent Pixel 9 series is insane! 😞

Six months ago, I was tinkering with the idea of re-using my tablet as second TRMNL

Now that idea is in GitHub with 50+ stars helping others do the same.

And today, it's available on Google Play! 🎉
