I've been running multiple AI agents locally and ran into resource contention issues when they'd both start builds at the same time.

I hope that every programmer I know reads and internalizes this pronto. A foundational document for LLMs in engineering practice. Much here should be obvious, but depending on your POV you will find crucial guidance here in one place or another

We need clearer vocabulary for describing how AI tools operate across the layers of a code base. They can act as productivity multipliers, but they also introduce tradeoffs. This article proposes a framework for discussing those tradeoffs. blog.mmckenna.me/the-piston-a...

Microdosing AI for Mobile Dev by @mmckenna.me blog.mmckenna.me/microdosing-...

Thanks for including my article about small AI usage for mobile dev! 💚🙌

I started a new "Applied AI" series on my blog. I'm focusing on finding ways to use these tools in ways that provide real value. blog.mmckenna.me/series/appli...

Here's some tangible productivity gains I've found for using AI! blog.mmckenna.me/microdosing-...

Wrote a lot of thoughts on junior developers, AI, and what I strongly feel is going to become the defining challenge of our industry's next generation. www.zacsweers.dev/forklifts-re...

TIL about the "Minimize comments" option in Github PRs. Hide all pre-existing review comments on a PR to review without distraction.

You should read this super cool blog from Tom! This is a result of a month long investigation where he found a core bug in the Android Framework USB handling code that led to VM freezes. engineering.block.xyz/blog/ending-... #AndroidDev

Does anyone run internal bug bounty, code deletion, fixit weeks, or other gamified things to add some focused fun to their teams flow? If so are there products or other ways in which you host leader boards, call outs, prizes?

This is one of those things that actually connects the dots on useful AI and has some real "wow" moments. The accessibility implications of this are incredible.

Remember the marble diagrams used to explain RxJava? My brilliant colleague Kostya 🧙‍♂️ has made an interactive explainer for Kotlin Flows to match! Find the magic here: terrakok.github.io/FlowMarbles/

Not to brag but me and @mmckenna.me got to be up close and personal to @duolingoverde.bsky.social 's butt last night! The things dreams are made of! #dcnyc25 @droidcon.bsky.social

Anyone making cool MCP servers? Especially with the Kotlin SDK? I'm giving a talk next week at #DroidconNYC and would love some examples to point people to!

I'm excited to be speaking at #DroidconNYC next Thursday, hope to see you there! I'll be covering how to handle configuration changes in Compose, and specifically trying to answer the question of what you should put in android:configChanges and - probably more importantly - why. #AndroidDev

Live now! Exploring navigation3 again, hopefully getting into persisting backstack: twitch.tv/adammc

First take on Android Studio Liquid Glass macOS icon. Icon Composer makes this super easy to play with. Wow.

What's better than lots of great code? No code! I wrote about a recent tech spec review and how a teammate and I helped simplify a proposal down to nothing! ryanharter.com/blog/2025/06...

Instead of a presentation, this year I'll be leading one of the roundtable discussions at Droidcon NYC! This is an open and collaborative conversation that anyone can participate in, discussing the current state of Jetpack Compose migrations in 2025, and the work still to be done. Come hang out!

What’s your best pro tip for live coding during a talk? I’ve been thinking about different ways to handle it and not sure which one I actually like best. I've seen a few approaches, each with some tradeoffs.

The agenda is live!!! 🏃🏃🏃

See you at Droidcon New York! #dcnyc25

I'm very excited to show off some crazy things with this talk at @droidcon.bsky.social NYC! #dcnyc25

I'm speaking at DroidconNYC 2025! Talking about Compose multiplatform, adaptive apps for multiple screen sized, media, oh and how they fit into an open source bluesky client! nyc.droidcon.com/tunji-dahunsi/

My talk was accepted! Hopefully I'll see some of you at @droidcon.bsky.social NYC in June 💚 nyc.droidcon.com/matt-mckenna/ #dcnyc25

Yay, Block (née Square) has a new engineering Blog! engineering.block.xyz/blog/

Very excited to see what comes of this! There's always been a few great talks in the lineup at Droidcon about tech leadership. Very cool that it's getting its own track!

1. LLM-generated code tries to run code from online software packages. Which is normal but 2. The packages don’t exist. Which would normally cause an error but 3. Nefarious people have made malware under the package names that LLMs make up most often. So 4. Now the LLM code points to malware.

Here are the projects I made in The Great Goose Off today with @opensource.block.xyz Good luck with the chaotic auth 🫣 github.com/himattm/grea...
