Well done to Slack for breaking the app in new in exciting ways. This time, clicking on Windows notifications doesn't open the app anymore. Of course this is on top of the *years* old bug that clicking on a notification unmaximizes the windows on a secondary monitor.

How do you configure @renovatebot.com to not automerge AGP updates? This doesn't seem to work. #android #dev

Bye bye, context receivers 👋 github.com/JetBrains/ko...

Could Slack finally stop messing with the freaking sidebar?

Kotlin 2.2.21 and 2.2.20 have a lot goodies in them. In my video, I'm looking at the highlights! www.youtube.com/watch?v=QWpp...

For WebStorm 2026.1 we want to hear what matters to you. Vote for issues or feature requests and we will do our very best to get those into the 2026.1 release!

I've written a small blog post about how context parameters change API design in Kotlin serranofp.com/blog/context... Feedback and discussion is more than welcome!

Context parameters are almost here, let's try migrating a real codebase to them and see what happens! If you've heard of them but haven't had the time to dive yet, follow me to discover what they can and can't do right now, ahead of their final stabilization. ivan.canet.dev/blog/2025/10...

We released Compose Hot Reload 1.0.0-rc01 🎆 What started as a happy accident was promised to be pushed towards stability as quickly as possible, allowing you to rely on a stable user experience. github.com/JetBrains/co...

Published a KEEP on suspend lambdas and anonymous functions: github.com/Kotlin/KEEP/...

Google is axing POP based sync between an external inbox and GMail. Is anybody aware of (or maybe building) an external solution? Or do I need to build it myself? support.google.com/mail/answer/...

WTH is YouTube doing with this auto dubbing?

Some Kotlin highlighting bug in @compiler-explorer.com sent me down a rabbit whole of formal grammars, lexers and contributing to tools I use daily. flofriday.dev/posts/50-sha...

It's so cool to see the unrelenting progress of Kotlin and Compose Multiplatform....all the moving pieces steadily coming together!

SEO but for AIs should be called LLMO (pronounced "Elmo").

Took me long enough to realize that @gradle.com's api() dependency should be used when you expose a dependency's types in your own public signatures.

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! Check out the details: www.youtube.com/watc...

Is there some universal law that any UI element related to AI needs to have a gradient and sparkles?

I think I found a really nice improvement for the NONE_APPLICABLE diagnostic in @kotlinlang.org today. In addition to listing all the candidates, we'll soon also print the reason why it wasn't applicable. #dev #kotlin #compiler

The « Building a RESTful Web Service » #Spring guide is now available in #Kotlin in addition to Java. We are collaborating with JetBrains to add Kotlin code snippets to the 10 most popular guides. spring.io/guides/gs/re...

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).

New KEEP (@kotlinlang.org feature proposal) about static members and type extensions. Read and leave your feedback at github.com/Kotlin/KEEP/...

Refixtoring - when you set out to refactor some code but in the process fixed a bunch of bugs. Or maybe you just wanted to fix some bugs but ended up rewriting a whole bunch of code. #dev #programming #refactoring

Not from this weekend, but I have to brag about this slide: I defined a list of code samples which are each highlighted by Storyboard using an ANTLR parser, and each transition is completely automatic thanks to a "MagicText" Composable. LaunchedEffect to loop though samples and done.

Call for Feedback: github.com/JetBrains/co... Compose Hot Reload, targeting beta hopefully soon.

StackOverflow saving the day again. Absolutely no mention of stateDefinition in the official #Compose Glance docs but stackoverflow.com/questions/77... explains it perfectly.

Try out Compose Hot Reload alpha04! It contains some nice fixes for Windows and the Runtime Tracking. github.com/JetBrains/co...

For five years I've been member of the Google Play org of my 2nd last employer that's now defunct. There is no way to remove yourself from an org if you're not an admin. According to issuetracker.google.com/issues/35889... 610 other people have the same problem 😢.
