Came across this picture from KotlinConf 2019.
Last KotlinConf someone approached me, and told me about an interesting talk they heard at Lambda World. The speaker, it was me with a beard 🤣
If there is one thing I've always loved is talking about Kotlin 😁 With a beard, or a moustache!

Did you know that all the Kodee assets, including the emojis and animated emojis are available on the Kotlin website! 😱
It's encouraged to use them, and have them inspire your creativity.
So get them now, and start spamming your colleagues with Kodee on Slack now! kotlinlang.org/docs/kotlin-...

Saturday I'll be speaking online at droidcon Bangladesh about Full Stack Ktor development! I will be showing you how to transfer your existing Android, and Kotlin knowledge to the server side. This can help you to take control of your own BFFs, build your own products back -and front, and much more!

#KotlinConf came -and went. My first one as Developer Advocate, and at @jetbrains.com.
Had amazing talks with so many people, so many new faces. Feeling pumped for another year of Kotlin growing in all directions, and seeing you all again!
Feeling blessed with such an awesome community 🥰

I have another Kotlin cat sticker! Kategory was the old name (& logo) of Arrow-kt.
Due to merging with funKtionale library, we felt we couldnt' keep the name or logo but damn... that logo was 🔥 Perhaps I should just cut off the name, and hand them out. I got like 100~200 left.

#Kotlin Exposed just dropped 1.0.0-beta-1 🔥🔥
With #R2DBC support! 😍
The (Exposed) cuttlefish is well-known for its outstanding mimicry ability that enables it to blend seamlessly into any environment (or dialect 😉). And now reactively!

Yes, it is a major quality of life improvement! Ktor will also allow you to directly retrieve deserialised configuration from the Application 😍
The previous example uses Ktor's new DI module, but the snippet below is relying only on the ktor-server-core module.

Have you tried #Kotlin notebooks yet? They're now bundled in IntelliJ IDEA 🔥
They're really great for prototyping and experimenting with Kotlin code in a fast and interactive way!
Here I am testing prompts, and tool calling with LangChain4J. Copy the gist, and try yourself tinyurl.com/4njwddy2

You like lambdas? The track function accepts a suspend lambda with a suspend lambda argument 😬
If the composition fits, it sits.

Came across this old (super cute) #kotlin sticker this weekend.
The community and ecosystem has grown so much since 🥰
Didn’t think it was possible but I think I love Kotlin even more now.
