New Kotlin video! Context-sensitive resolution is one of those features that will kind of quietly blend into the background while making a lot of code much nicer. And you can already try it in Kotlin 2.2 as an experimental feature!

The case against `kotlin-dsl` I fear no man. But that thing... It scares me!

A great breakdown by @mbonnin.net on why you should avoid the "kotlin-dsl" Gradle plugin. Just write your binary plugins using a normal "org.jetbrains.kotlin.jvm" plugin

I've added an MCP Server to a simple cli tool, that wraps around adam (for Adb) so a MCP Client can interact with your connected phones. github.com/mikepenz/adb...

I've been trying out @jetbrains.com Junie over the past few few days, and have pretty blown away with it.

I've managed to do everything from a complex refactoring of Haze (with follow up tasks), to fairly complex string manipulation (pretty printing data class toString).

Thank you so much @kotlinweekly.bsky.social for featuring github.com/mikepenz/adb... in the latest newsletter. ❤️

This can be used to make that important action in your app feel much more special.

Added some new tools the last few days to the `adbfriend` (github.com/mikepenz/adb...) #MCP server. Just had it organize my downloads folder on the phone, which was a mess 😅.

Congrats to @kotlinconf.com organisers....it was, as always, an amazing event! My general feeling after attending (coupled with announcements coming up to the event) is that we've "unlocked a new level" in the Kotlin ecosystem. Very exciting times ahead!

🥳 Excited to share our latest blog post on Material 3 Expressive Motion Theming!
