Android 17’s better HTTPS privacy is rad. I’m proud that OkHttp 5.5 makes it easy to adopt.

Closing a Critical Internet Privacy Gap for Billions of Users: Android 17 Rolls Out ECH Support

When you launch an app or visit a website, you likely assume your connection is private. In reality, a critical privacy gap remains. Even…

Made two new herdr plugins. First one is an account switcher, for when you have multiple accounts with the same provider. Works with Claude code and Codex cli. Second one is auto continue. Got a bit redundant now that Claude ships its own, but this one works for Codex too. 1/2

Had to revert something that gpt 5.6 Sol did today (simple button width customisation for different font sizes) because it went from not getting it right a few times to achieving a completely over-engineered solution. Really feels like models are degrading lately.

Confetti (github.com/joreilly/Con...) now includes conference info for @droidcon.bsky.social Berlin 2026. Big shout out to @marcellogalhardo.dev who contributed ton of really nice UX updates recently (including use of @chrisbanes.me's very cool haze library - github.com/chrisbanes/h...)

Workflows are cool. Until you use one while using Fable, and forget to tell it to delegate tasks to weaker models. RIP session, you had a (very) short but full life 🫡

Someone drove a vehicle into crowds at Berlin's Pride celebration tonight, seemingly deliberately. Josh and I are home safe. If mutuals could check in I'd really appreciate it. Please take care of yourselves tonight.

Hot Reload on iOS is actually real. This is just a PoC of iOS hot reloading with Compose HotSwan. Working on completely different compiler plugins from scratch for Kotlin Multiplatform. No rebuilds, no reinstall, no need to navigate back and recover your state, and this could cut your build steps.

Created two plugins for Herdr to fix two annoyances of mine: knowing which idle agents have shell processes running, and which have output that I haven't read yet (ordered). Wonder if it's worth it to open source these, anyone can ask an agent to create their own nowadays 🤔

Google starts charging developers for Firebase Remote Config! 😱 firebase.google.com/docs/remote-...

The PoC of Hot Reload on iOS, Compose Multiplatform. Compose HotSwan is taking a step toward KMP support.

As models and vendor harnesses improve, so should your personal harness. That said, massive cleanup over at my skills repo 😂 Removed (hopefully all) unnecessary bloat that most agents don't require anymore. Check it at github.com/rcosteira79/...

Hah, won a little trophy at a Lego building competition. This obviously 100% reflects my skills on building software. #GoogleIOConnect #BuildwithGemini

Nice set of skill creation tips to follow. Unfortunately, they're sometimes hard to follow as well. My favourite one is "less is more", since agents keep getting better, thus deprecating your older skills little by little. The less you write, the less you have to clean 🤓 #GoogleIOConnect

Ngl, this looks pretty cool. Time for I/O Connect!

Seems like Google never heard about Ballmer peak 😄

A skill that mixes extracting a spec from the user with DDD? Definitely worth checking! Gonna disable my Superpowers workflow and use vanilla Claude + this and my other skills for a while, since this seems like a better alternative to Superpower's brainstorming.

Android is Compose-first, and the Views system is now in maintenance mode, meaning it will only receive updates for highly critical fixes.

As writing code becomes cheaper, it becomes increasingly important that we nail the architecture constraints, so that AI agents have clear guardrails to work with. Feels like a great time to dust off the classics.

Friendly reminder to all android devs to clean up your resources and migrate any images to .webp when you have the time. Between these two builds, we did exactly that in one of our 20 something modules. It's not a huge win, but I'd say it's already noteworthy for an app this size.

Updated my android skills so that they get out of each other's way, as well as reference each other when needed. Also created a plugin to make it easier to install and update them 😄 github.com/rcosteira79/...

Every Gradle dependency analyzer I've used was very confusing, and hard to reason about. So I built my own 😄 It lets you isolate each module, check for transitive dependencies, or check which components actually create the dependencies! Check it at github.com/rcosteira79/...

GitHub - rcosteira79/Simple-Dependency-Analyzer: A Gradle plugin that generates an interactive, self-contained HTML report visualising your multi-module project's dependency architecture. It doesn't just show you which modules depend on each other — it shows you why, by tracing module-level edges down to the exact classes involved.
