kotlinlang #random

Kotlin related but not a Kotlin specific question. I'm trying to understand the difference between regular collections and sequences. Can someone ELI5 the difference between

list.map { it * 2 }

and

list.asSequence().map { it * 2 }.toList()

? Also accepting links to posts/youtube videos that explain it if it's a rabbit hole.

I'm porting some code from cpp and I'd like to know what means

(void)debugDraw;

in the following?

void	SphereTriangleDetector::getClosestPoints(const ClosestPointInput& input,Result& output,class btIDebugDraw* debugDraw,bool swapResults)
{
	(void)debugDraw;
        ....
}

Hi Everyone, I have been tasked to create a Technology Roadmap/Rollout Strategy for adopting Kotlin. Can anyone point me in the direction to any reference material that I can learn how to do it (not sure how to create any of these documents)?

Hey, Kotlin jumped from 48 to 28 in one month, and now has almost one percent of popularity on TIOBE https://www.tiobe.com/tiobe-index/

Is there a way to disable youtrack update mails only for new votes? I'm interested in seeing the comments and status changes but I don't need a mail whenever someone votes.

@orangy ^ annoying gif totally unrelated to Kotlin, I’d vote this as spam 🙂

Why isn't Pivotal (https://www.quora.com/When-will-Kotlin-be-mature-enough-to-be-used-in-production) and Travelex (https://android.jlelse.eu/kotlin-in-enterprise-71adbdb3cf8f) mentioned on the Kotlin website (https://kotlinlang.org/docs/reference/server-overview.html)?

Hi! 🔔 You know how it is always suggested to use

asSequence()

when applying several collection operations like

map

filter

one after another? I was wondering how big the performance win is for those cases. Could you please throw at me some realistic-ish examples of ⛓️ chained collection transformations so I could measure them for a project? 🔬

I was surprised to see there was quite a lot of interest in the server side for Kotlin

Yeah, Spring has adopted Kotlin quite nicely, and there's also Ktor, which is a simpler framework built specifically with Kotlin in mind, coming from JetBrains. Great stuff! 👍

I’ve just read the java code convention document once again and I haven’t found any restrictions regarding underscores in package names. Looks like it shouldn’t warn us. And it does warn me only in kotlin files, what is strange

Not sure if you have an Android phone but when you set an alarm clock at 11pm for 7am, the clock says "Alarm set for eight hours from now"
