Really appreciate Lombok support! Having to delombok was a major starting hurdle when introducing Kotlin into our existing Java services, this should help a lot with that!

thumbs up for lombok support, it'll allow better adoption in existing Java projects

Антон, большое спасибо за видео!

Ps.: в characters первый звук произносится как «к», а не «ч» :)

The day Jetbrains officially provide LSP for other IDE, will be miracle. I love kotlin but resource requirement for IntelliJ makes it hard to use it on my 6 year old laptop, even with upgraded ram. I would love to use vscode but community maintained LSP is always missing latest features.

How to run such bytecode viewer for Kotlin (1:43)? It looks different from than the default one in IntelliJ. Thanks!

The audio doesn't match the lip sync, which normally wouldn't matter that much, but since you placed a talking avatar in the screen, I find it quite distracting. Can this please be fixed?

What... Why it named after Indonesian island? Like Lombok?

Hello i am a beginner to programming. I am trying to learn Kotlin, and its going ok.

I was doing fine using intelliJ, and doing some tutorials, everything worked fine.
But now i get this error, and I cant run any of my programs anymore :-(

Kotlin: [Internal Error] java.lang.OutOfMemoryError: Java heap space

I tryed to increase the memory.
In IntelliJ Help -> Memory settings
But it dosent seem to correct the problem :-(
