If you missed @kotlinconf.com 2025, you can catch talks on kotlinconf.com, including mine, where I deep-dive into a couple of relatively recent features to learn about Kotlin specifically and find general takeaways for software development and practice.
KotlinConf 2025, May 21–23, Copenhagen
KotlinConf is the official Kotlin conference by JetBrains. It is a place for the community to gather and discuss all things Kotlin.

Jetpack Compose looks simple, but under the surface is a runtime that tracks tree positions, manages groups, and invalidates state precisely.
If you do not understand that system, you cannot use it efficiently.

I used trial and error to get the order right for this for so long…until it finally made sense.
In a Python comprehension, why does the `if` sometimes go after the `for` but sometimes before it? [Spoiler alert: it doesn't]
