I've been using Kotlin with Android for over a year. There have been few problems with SDK interoperability. Since I started using Kotlin Google blessed it. The one annoying gotcha was JSON parsing. If the fields on your models are not declared as nullable, they can still be set to null in the JSON which causes a NPE.

I found the transition from Java to Kotlin painless because Android Studio (Intellij) holds your hand all the way. If at first you're unsure of the syntax, you can just write code in Java and convert to Kotlin.

I agree that the null-safety Java interoperability does not work properly if the Java code is not annotated correctly (or you're parsing JSON) but I'd still prefer to have it than not.

I like Kotlin because: * If is an expression and it feels so clean * Functions are first-class (you can pass functions to functions) * Kotlin is less verbose than Java so there is less to read and write * You don't have to write "new" * Constructors are cleaner (you don't have to write (this.a = a) * The map function (on Android we were stuck on Java 7)

This is not Hacker News material.

That's weird all the CCC videos were returning 404. The link appears to be working again now. It's a few days since I watched but I inferred that SSH may have some undisclosed vulnerabilities.

Would wager that a copy of the Bitcoin blockchain outlives many banks.
