No doubt !

I'm curious, how common is it in idiomatic Kotlin code to do fancy stuff like star projections, etc with the type system?

As I know short-circuit is the electric device to cut a wrong electric connect

When are contracts planned to leave experimental status?

I'm unsure what this would be called in Kotlin

I wanted to make a custom range

any way to fix that? is that even possible?

I've literally copied the range implementation from stdlib and changed the class it operates on

Example :

fun sortByFooBar(foo1 : Foo, foo2 : Foo) : Boolean {

return if (foo1.something() == foo2.something() ){
            foo1.some <= foo2.some
        } else {
            (foo1.isSomething()
                    || (foo1.isOther() && !foo2.isThis())
                    ...
        }

}

How do I write a class A such that it has some attributes public and some attributes only accessible by class B? I’m thinking about something like friends in C++, or

fileprivate

visibility in Swift.

What do Android devs think of the Unidirectional Data Flow + LiveData pattern in Kotlin? In version 2.0 I improved the view events, effects, and cleaned up the ViewModel with Kotlin Coroutines. 👩🏻‍💻 https://proandroiddev.com/udf2-0-5052c3e1c62a?

https://twitter.com/kotlin/status/1208073703327764481 Are you wondering if Kotlin can be used for data science? In a word, yes! Here’s a status update on the Kotlin tools, libraries, roadmap, and other useful resources for data science that you can already use today. https://t.co/eziFdne6W9 Twitter

Making Kotlin Ready for Data Science This year at KotlinConf 2019, Roman Belov gave an overview on Kotlin’s approach to data science. Now that the talk is available for everyone to see, we decided to recap it and share a bit more on the current state … Continue reading →

What do you guys think is the most elegant solution to calculate letter frequencies. If you have other suggestions, I'd like to hear them

Good day today. The KMP project we have been working on for the annual CodeWeek event is a finalist! 250 teams competing, we are one of the top 25 going into the finals in January. WatchOS KTOR client made it just in the nick of time! Still needs polishing and a good amount of refactoring, but I think the main point proven - we share logic and networking across multiple targets (and planning to add more) https://github.com/dmitrish/kinsight-multiplatform

Hi, I have a generic Java method parameter, which is returned from a method

R extends NodeReadOnlyTrx & NodeCursor

. However, the type in Kotlin is

NodeReadOnlyTrx!

. I'm calling another Java method which retrieves a parameter of type

R extends NodeReadOnlyTrx & NodeCursor

How do I get the right type inferred?

https://twitter.com/kotlin/status/1209398316066205697 Escape callback hell when consuming APIs by using coroutines when building your applications. When you're using Kotlin/JS, coroutines play nicely with promise-based browser functionality, such as window.fetch or Body.json. #KotlinTips https://t.co/A8krEUGgb0 Twitter

I try to move it to other block, where we bot overriding but 8n othere place is same error

anyone familiar wiht using FailSafe? https://github.com/jhalterman/failsafe i’m struggling trying to get the types correct

oh, lord, it was because i copy pasta’d a generic type param as

Object

instead of

Any

i.e.

val retryPolicy = RetryPolicy<Object>()

Maybe it's interesting for someone, as I've written the REST-API Server with Vert.x and Kotlin (also using Coroutines) and I want to provide a kotlin based client as well: https://medium.com/@johanneslichtenberger/how-i-develop-a-temporal-database-storage-engine-in-the-advent-of-byte-addressable-nvm-ba152860e71

So... are there news on the ability to wrap comments to the next line in Kotlin? https://youtrack.jetbrains.com/issue/KT-19963

this issue is kind of... dead

seems like the sort of thing that it would have, kinda like a lazy takeIf

man… going back to writing Java after writing Kotlin almost exclusively for a couple years… brutal.

some of my pain points here are b/c I’m using java 8 still, but there’s just so much that’s still so ancient feelling

@rustyrazorblade Yeah I did that once too. It sucks 😕 But when you go about to Kotlin again you rediscover your happiness again 🙂
