Today’s military strikes on Iran — carried out by the United States and Israel — mark a catastrophic escalation in an illegal war of aggression. Bombing cities. Killing civilians. Opening a new theater of war.

Thousands of good people were laid off by Block (Square and Cash App) today by their chickenshit leadership. Hire them, this is all Block's loss.

Metro 0.11.0 is out now, along with a new proposal system called MEEPs! www.zacsweers.dev/metro-0-11-0... Release: github.com/ZacSweers/me...

Android developer registration starts some time next month - expect to hear a lot more from the groups trying to oppose it over the coming weeks

Excited to be speaking at KotlinConf again, this time about how Metro's features work under the hood!

one of those things you need to watch if for no other reason than the trump administration doesn't want you to:

Every time I see a post like this I go ask a developer I know at that company if it's true and every single time it's misleading at best, if not outright horse shit. techcrunch.com/2026/02/12/spo...

Vibe coded a little CLI + wrapper github action to auto-delete bluesky/mastodon posts/reposts/likes. Idea is that you can stick this in a github actions cron workflow and let it periodically run+delete posts beyond a configurable horizon. Supports keep lists too. github.com/ZacSweers/skyscraper

Just published "Where are all the staff+ Android product engineers?" www.zacsweers.dev/where-are-th...

I've been using Claude Code 4.6 to try to help with some CI boilerplate setup in Metro and at least three different times now it's just gotten stuck and concluded it should just delete all the code that isn't working. Would not advise using it, it's clearly a pattern at this point.

I wrote about the Epstein files (gift link) www.theverge.com/tech/874721/...

I am begging Zendesk to get their shit together today, clearly being used as a relay attack today

Just want to take a second and appreciate @sarahjeong.bsky.social, @reckless.bsky.social, and the whole team at @theverge.com for consistently meeting the moment here. Fearless reporting, pulling no punches. Proud to be a subscriber.

👋 Hi everyone, I’m enabling GitHub Sponsors for Metro If Metro has improved your developer experience or saved your team's build times, I’d appreciate the support! Full pitch and ROI napkin math here: www.zacsweers.dev/sponsoring-m...

New Yorkers (especially soccer players) — ICE has abducted multiple people at Pier 40 this week, come up in a couple local pickup soccer WhatsApp groups I'm in. I wouldn't recommend playing at Pier 40 for the foreseeable future. hellgatenyc.com/hudson-river-...

Y'all, Shoresy is so good

🚇 Metro 0.10.0 is out! - @Inject is now optional for most @Contributes* annotations! - KMP Milestone: FIR hint/top-level function gen enabled by default in 2.3.20+! - Perf: Sharding and switching providers support - Lazy maps - LOTs of fixes and improvements github.com/ZacSweers/me...

One of the most frustrating things under Salesforce was how obvious it was that Benioff just tries to copy what (he thinks) other tech CEOs do without any real understanding of why or how to implement those decisions. timesofindia.indiatimes.com/t...

The “prosecute the former regime at every level” candidate has my vote in 2028.

Not sure who else needs to hear this but an OSS maintainer taking the time to privately give you a warning is doing you a massive favor

This one is resonating today. #Andor

Today is incredibly draining. My home island is just off the coast of Venezuela, we grew up with Venezuelan culture all around us. Our national bird is the Venezuelan Troupial, I have it tattooed on my arm. Maduro is evil, but the Venezuelan people are going to be crushed by how this is being done.

“We don’t have a contest culture”. Ok buddy, sure, but you: - only hire “top talent” - reward individuals, not teams - fire low performers - have a Wins channel where you “celebrate” individuals - laser focus on KPIs/OKRs - don’t hire juniors - do RIFs vs retraining Guess what! Contest cultures!

Neat blog series from Mounir Boudraa about how they're using Circuit with native SwiftUI for their KMP iOS apps! www.quo.com/blog/moderni...

Metro 0.9.0 is a big performance release focused on optimizing generated graphs! github.com/ZacSweers/metro/re...

This could, and I'm not overstating this, save human kind

✨📊 Refreshed the Metro performance docs page with new benchmark results (both build and runtime) and interactive charts. Pretty happy with how this came out and the next release should have some nice improvements to runtime perf and reduced graph code gen size. zacsweers.github.io/metro/0.9.0-...

circuit-retained is dead, long live circuit-retained

Someone in the KMP live stream chat today asked if Circuit was still safe to use now that I'm no longer at Slack. It is! I'm still co-maintaining it with Josh Stagg (who is awesome and been behind a lot of Circuit's recent releases)

Metro 0.8.0 is a huge release! - Graph analysis tooling in both the compiler and gradle plugin - Removed deprecated runtime APIs - New MetroX Android and ViewModel artifacts - Broadened member injection support - Bunch of other bugfixes, improvements, etc github.com/ZacSweers/me...

Vibe coded some new visualization tooling into Metro using Apache ECharts ✨ Behold: CatchUp's DI graph

The build performance results 😍🫶

I've been on the program committee for droidconNYC for a few years now and attendee for nearly decade. I understand why they felt like staying in NYC wasn't financially viable, but moving to Florida (let alone Orlando) is such a disappointing decision, especially for LGBTQ+ members of the community

MoshiX 0.33.0 drops the need for proguard rule generation, meaning you can use it and its IR code gen entirely without needing KSP 🎉 github.com/ZacSweers/Mo...

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

Metro 0.7.5 has the Guice github.com/ZacSweers/me...

Excited to share Metro's original design doc. Pulls back the curtain on a lot of the historical community feedback and discussions that went into it in its early days! www.zacsweers.dev/metros-desig...

Zohran Mamdani in his victory speech: "Donald Trump, since I know you're watching, I have four words for you: Turn the volume up." The cheers in the room are deafening.

Metro 0.7.3 adds member injection interop, Kotlin 2.3.0-Beta2 support, and a bunch of other smaller goodies and fixes. github.com/ZacSweers/me...

Traveling to London tonight, but Metro 0.7.2 should mostly work with Kotlin 2.3.0-Beta2. There’s on API change that affects logging but is fixed in snapshots, will cut a new release prolly tomorrow after I fix a separate dagger multibinding interop issue.

School shootings and measles

Metro 0.7.1 improves diagnostic messages for missing dependencies and multibinding code gen optimizations. github.com/ZacSweers/me...

Metro 0.7.0 is out with dynamic graphs, implicit injects, and wasmWasi targets! Dynamic graphs have been a long time in the making and should unlock some pretty powerful testing patterns. github.com/ZacSweers/me...

Metro 0.6.10 introduces some new optional behaviors, interop with @BindsOptionalOf, and the usual host of other fixes and improvements! github.com/ZacSweers/me...
