@rokee: can you tell first why did you chose scala over everything else? for us to understand what qualities of a technology you count as important

@voddan i did not choose scala, i am just in the situation for choosing one language for my next project. I want to use statically typed language on the jvm, and there are two most modern language, scala and kotlin, i think scala has bigger community and has many frameworks(Play, akka), but kotlin doesn't. And, since it is not release 1.0, i just want to know why did kotlin user choose kotlin rather than other.. especially scala.

In my view point, kotlin has more simple syntax, and zero-overheaded null safy, but small community.

Of course, i think kotlin is nice language! I just wonder why did you choose kotlin though there is option for scala.

With you community will be slightly bigger, that’s how it works simple smile

I agree with you

Im already using kotlin in android platform.

kotlin is the most powerful language for android.

But server side, there are many options. So i just want to know the killing point of kotlin for server

😄

I would resist from commenting due to obvious reasons, but here at JetBrains we are using Kotlin on server quite a lot, and really happy with it.

What I’m dreaming of (and actually working on in #C0A974TJ9, but not there yet) is ability to have single retrofit-like interface and use it to implement server code, as well as consume on Android, and later on kotlin.js in browser.

That would be amazing. I look forward to seeing it come to fruition.

There are couple of things to design, implementation is not that difficult. One is how to support multiple API versions in single server, and not end up with MyAPI1, MyAPI2, etc interfaces

Another thing is that retrofit-style API doesn’t have a place to pass context, e.g. to check cookies, headers, etc. It doesn’t need one. So supporting exactly retrofit-compatible interface is either impossible, or will require some hacks like using ThreadStatic “currentContext”, which doesn’t work well with async, etc.

Otherwise it is pretty straightforward, most of the code is already there in this or that form, need just to explore interface and generate routes.

for the initial question - Kotlin works nicely with Scala and Java (8) frameworks, when Scala needs scala-oriented API due to a bigge paradigm shift

by "being nice with a framework" I mean that I use documentation meant for java user, and do not have ask on SO how to do things with a specific framework with kotlin

but I am not a scala pro, thou

i wonder how people answer that on a scala forum

with much anger and vitriol 🧌

@rokee: The Scala community is probably not as big as you think and from my perception, Scala is stagnating and probably slowly shrinking in popularity. Many reasons for that, starting with the poor IDE support even ten years after its inception and the somewhat directionless design the Scala team is following. Also, they seem to be more focused on dotty than scala these days, so bugs filed against the compiler are not getting fixed very fast

And yeah, in my experience, the Scala community is better experienced in read-only mode. Dare stepping in and criticizing it and you’ll get harassed, so I no longer do that.

Which Scala community? Scala is such an unopinionated language that there are many.

Or at least, several. Do you want a better Java? Or a worse ML? Or an Erlang on the JVM?

The freenode channel is probably the worst (400 people, only 10 really participating, all of them extreme FP advocates, which discourages beginners on a daily basis)

scala-debate and scala-users a bit better since there’s some moderation happening there

Kotlin hits the better Java pretty well, I think, and is opinionated enough that the community of people wanting the better Java don’t get mixed up with those making do with a worse ML or Erlang

<!here|@here>: what monitoring software are you using? NewRelic? GrayLog?

I use NewRelic, but I will move away from it, too expensive.
