Releasing today: 'ProggyForever': a new MIT-licensed scalable font designed to closely match ProggyClean which happily served as Dear ImGui default font for 10+ years: github.com/ocornut/prog... The new font is now embedded by default in Dear ImGui (compressed down to ~14 KB).

I want to take a second to appreciate @sebi.io giving me a chance to extend my talk abstract even tho i didn't manage to deliver. I hope i can try again for next KotlinConf :)

mood rn

Our GitLab server and some other services might experience some downtime within the next 48 hours due to a scheduled hardware upgrade. We apologize in advance and thank you for your patience :) -AH

TIL kotlinx.benchmark does support suspend benchmark functions in theory, but they're just missing the required glue code. Non-web via runBlocking and web via returning a Promise, which the runtime already supports. Why not implement a runBenchmark like with kotlin.test? :D

Benchmarked my async IO library for KMP against kolintx.io for the first time today on native. Looks promising :D

Me: You wanna review this merge request? @cach30verfl0w.bsky.social: Which one? I already reviewed that one. Me: Nah, the one i just sent you lmao @cach30verfl0w.bsky.social: Fuck off, don't act like i check my messages You may not like it, but this is what peak communication looks like.

Software devs coming to teach you clean architecture in 2026. Now more than ever

The overuse of Gen AI is great actually! It makes more people more annoyed by it, leading to a quicker decline of usage.

Kotlin Test breaks badly on WASM/JS targets if your test function names contain spaces 🥲 The Gradle HTML report mechnism just hard-crashes with an IOOB exception lmao. That didn't happen before in Gradle 9.2.1, only since i updated to 9.3.0 this seems to be an issue lmao.

PSA: Starting Android Gradle Plugin 9.0 (or the latest stable version of R8): R8 will automatically optimize all Intrinsics.check* APIs in Kotlin automatically ! This should greatly help improve app performance (especially Compose given the large Kotlin library API surface).

The interesting applications of AI are all, like, "we built an open framework that uses processors on recycled cell phones to identify and triangulate the location of rare bugs in tropical rainforests" while big tech is going "what if we burned down that rainforest to summarize your emails?"

The Kotlin ecosystem might not choose a strict 'SemVer' notation (and it's gonna be fine!) blog.sellmair.io/the-kotlin-e...

DHL has been really testing my patience over the last week(s) -.-

When I find myself working in a big pile of metaphorical manure, I can always bring out this email I received on this day, nine years ago...

okay but you might wanna actually watch star trek first

We are experiencing a small outage due to issues at our hoster. GitLab and all other sevices should be up again in a couple minutes. -AH

Compose Multiplatform 1.10.0 is out! 🎉 What’s new: ✨ Common @​Preview annotation 🧭 Support for Navigation 3 on non-Android targets 🔥 Stable and bundled Compose Hot Reload Learn more: https://blog.jetbrains.com/kotlin/2026/01/compose-multiplatform-1-10-0/

Good morning interwebs

Looks like #WasmEdge is the first standalone #Wasm VM that supports and enables #WebAssembly 3.0 out of the box. Big milestone. Shout-out to the team! 🙌

TIL Kotlin/JVM supports suspend main entrypoints, but Kotlin/Native does not.

Reminder that in 2026, just like in 2025, `*.main.kts` files are better replacement for most of your scripting needs! mbonnin.net/2024-11-21_s...

Sorry floofies, it's time to take the tree down!

It's time for the passing year! ✨🌟✨Happy new year!!✨🌟✨ Wishing you the best as always, health and success for you through 2026! Keep it up!

this diva..

Can't wait for the loosened up, non-perfect, but quickly shipped AI-enhanced updates to hit my banking and insurance services next year. Im sure there will be no issues there at all.

Merry christmas y'all :3

2025 marked #Java's 30th birthday. We celebrated loud, proud, and in style 🎉 To end this landmark year properly, update to the latest version of the Java 30 Anniversary plugin jb.gg/1lak0x and unwrap a festive Duke for the holidays, plus the full Duke collection to boot.

Little lunch break thread: So, i recently got that sweet FTTH upgrade for the @karmakrafts.dev HQ, however, the ISP forced me to use an external ONT. I really want to run the fibre through my own patch panel and then directly into my UDM Pro.

Generic placeholders are such an underrated feature in Kotlin :D

v2 of our MMIO library for #Kotlin Multiplatform is out now! If you need to handle large files with random access, this is the library for you. Get it while its still hot: github.com/karmakrafts/...

Want proper threads and synchronization primitives in #Kotlin Multiplatform? Filament, our threading library is now available for Kotlin 2.3! Grab the 1.6 release here: github.com/karmakrafts/...

lazyStatic, our library for static locals in #Kotlin Multiplatform now supports Kotlin 2.3! Grab the 1.4 release here: github.com/karmakrafts/...

The Introspekt compile time introspection framework for #Kotlin Multiplatform now supports Kotlin 2.3! Grab the new 1.6 release here: github.com/karmakrafts/...

Iridium, our IR/FIR testing framework for #Kotlin now supports Kotlin 2.3! Grab the new 1.10 version while it's still hot: github.com/karmakrafts/...

withAndroidTarget doesn't work with the new androidLibrary{} KMP target -.- You can do withCompilations { it is KotlinMultiplatformAndroidCompilation } as a workaround tho.

My prayers have been heard

Kotlin 2.3.0 is out! My faves (no order) 😅 - Unused value checker - Improved Context Sensitive Resolution - Java 25 Bytecode - JS suspend function export - Better Swift Interop - Explicit backing fields - New Kotlin Uuid APIs and there is much more! Check it out: blog.jetbrains.com/kotlin/2025/...

A dream came true today :D

After much fighting, i am dropping Kotlin/JS support for my IR framework/interpreter. The type system quirks and reflection behaviour just make it highly impractical. BUT - you can still use it in the browser via WASM.

TIL Kotlin/JS evaluates Byte::class.isInstance(10) to true but evaluates Byte::class.isInstance(10L) to false, this just cost me more time than i'd like to admit.

Need compression in your #Kotlin #Multiplatform project? Check out our new library Kompress, a zlib API for #KMP! karmakrafts.dev/2025/12/13/k...

TIL CInterop horribly messes up relative paths because it uses the Gradle process CWD instead of the project directory. Setting -Xproject-dir myself is ignored because the internal CLI builder seems to specify its arg last, always overriding mine..

@jetbrains.com You fixed the KN debugger for me in 2025.3, thank you SO SO much <3
