@pegnarro Thanks!

@bashorov Welcome!!

Some kid on the plane: > Guys, c’mon, be happy! We go to Barcelona.

@evacchi @sergialmar @wasm_io @oscar_spen @juntao @d_philla How about Wasm inside AI? 🙃 x.com/ChristosTzamos…

I can't believe @sergialmar fell for it! This year I'm honored and humbled to be on the @wasm_io stage for a panel! Come and watch me blabber and stutter, while @oscar_spen, @juntao and @d_philla actually say something smart about… 🥁 "Running AI in Wasm"

2 great improvements #Kotlin 2.3.20 brings for #Wasm target users: 1️⃣ Optimizations that * significantly reduce memory consumption during compilation, especially in large projects. ~65% for clean builds and ~21% for incremental builds. * up to 5 times faster incremental builds

@kotlin x.com/bashorov/statu…

📢 Kotlin 2.3.20 is out! Here are some of the highlights: ✅ Gradle: Compatibility with Gradle 9.3.0 and Kotlin/JVM compilation uses BTA by default. ✅ Maven: Simplified setup for Kotlin projects. ✅ Kotlin compiler plugins: Lombok is in Alpha and improved JPA support in the kotlin.plugin.jpa plugin. ✅ Kotlin/Native: New interoperability mode for C. ✅ Language: Support for name-based destructuring declarations. ✅ Standard library: New API for creating immutable copies of map entries. Learn more: ➡️ kotl.in/2-3-20

2️⃣ Up to 30% size reduction of production distribution.

Check out a sample server using wasi-http built with our early #WebAssembly Component Model support in @Kotlin! 🤩 github.com/Kotlin/sample-… Still early, but very satisfying to see it working ✨ Give it a spin and share what you build 🚀 #Wasm #Kotlin #ComponentModel 👇

@kleshney Check it out! 🍻 github.com/bashor/kotlin-…

@bashorov I was able to figure something out based on your old 1.9 template. But maybe we no longer need to rely on regex monkey patch of resulting mjs

@bashorov any chance you could update your cloudflare worker kotlin wasm example with the latest kotlin version?

@U8N20 @wasm_io Sad 😔 Maybe another conference or #wasmio27? 🤞

@bashorov @wasm_io Not this year 🥲

Conference season kicks off for me next week at @wasm_io in sunny Barcelona ☀️ How about you? #wasmio26 #wasm #WebAssembly #conferences #devcommunity

@JamesWard 5/5 In the end, I believe it would be valuable for everyone: languages, developers, and end users.

@JamesWard 4/5 - Bonus point: Component Model may also help diversify web development in terms of used languages, not just allowing the use of many langs, but also mixing them in a single app, allowing easy closure of gaps where something is not supported for one lang but is for another.

Wasm Component Model for web APIs is coming! hacks.mozilla.org/2026/02/making… I can’t wait to use this with Kotlin/Wasm to build web apps. Also wondering what the possible intersection with MCP Apps will be. I’d really like my MCP Apps to just be a Wasm.
