can't share the details but I'm writing kotlin code for one of the biggest US telecom companies

Guys anyone developed app with kotlin which is production ?

On the blog post they refer to a Kotlin session at Google I/O, does anybody know anything about that?

The Kotlin talks don't seem to be on the schedule 😞

IntelliJ IDEA Ultimate is a superset of Android Studio AFAIK

sure would! It goes wherever java (and Android) goes

Has anyone wondered about the perfect timing of https://medium.com/square-corner-blog/square-open-source-loves-kotlin-c57c21710a17? Since @jw will give a talk about Kotlin at I/O, I guess they must have known before about the anouncement.

still cannot make my company pay for it =(

How do I document a return value that uses generics in kdoc? I want to do something like

@return [Observable<List<Card>>] description here

but it's not correct

@hhandoko You need JDK 1.8 to run the compiler, but you still can target the compiled code to run on JDK 1.6

Seems like I’ll need to switch JDK versions within the CI pipeline (compile first with JDK

1.8

then test with JDK

1.7

).

not sure if this is should be on #random, but thanks to google announcement kotlin just surpassed Scala in the metrics o number of stars on github (~8700 vs ~8200) and going up rapidly

@nkiesel what you want is a regular JVM sandbox. there is no need to search for a kotlin specific one.

I’m converting a big codebase from java to kotlin. There is a lot of concurrency. I have a class that has a method and inside of this method

notifyAll

is called. In Kotlin there is no such method because classes don’t inherit from

java.lang.Object

. Is it a bad practice to do

class Foo : java.lang.Object()

?

how many members do we have now on Slack here ? I see that this will grow a lot in the near future, now with the I/O announcement. Just wondering if we won't hit issues like : https://medium.freecodecamp.com/so-yeah-we-tried-slack-and-we-deeply-regretted-it-391bcc714c81

Has anyone a good sample how to interop Kotlin with Lombok-generated code? I’ve scoured Google but haven’t found a definitive answer suggesting that it should or should not work. Anyone got it working by using i.e Kapt?

is there any official sample project with the viewModel e livedata thing?

i know i can use for(i in 0..list.size-1). but too verbose

this sounds like premature optimization... verify you have a performance problem before cluttering your code with "speed improvements"

Yesterday, before Google announcement, kotlin had 8060 stars on github and scala 8200. Today kotlin has more than 9200 😱 I know that doesn’t represent a lot but still. It will be easier for all of us to say : “kotlin is the most appreciaded language of the JVM”. And the number of LOC should keep its rapid pace.

@orangy I’ve had it on my resume for a few years - sadly I never get asked about it.

This proper semver 2.4 -> 3.0 is what JB could apply in K versioning instead of confusing users with 1.1.2-4. Just my 2-4 cents 😉

i find it really weird that with the range operator the IDE automatically puts spaces like this:

someVar + 6..otherVar - 7

it now seems like the

..

has priority however the opposite is true

(When) will this be allowed -

inline fun test(test: () -> Unit = {}) {}

gave my presentation at work today - some feedback "Looks nice, but we have too much work to do"

But anyways, if you wanted to, you could edit them with community, its just that ultimate has a ton of features on top

It's Retrofit for databases

By the way a month back I read a medium post by a guy who was advocating on why people should not be using kotlin . As of now I must say of the features of java 8 are out of the box supported in android api levels up to 1 , kotlin is not a mandatory language for android its just first class. It will take like a year or two to be deeply integrated in the core elements of android. Its just that google has now made kotlin more relevant as a competition to app development on ios with swift. Yes there are similarities between syntaxes of swift and kotlin . Try to get well acquainted with java 8 concepts like stream apis , lambdas try with resources and much more and then try kotlin. One of my colleagues once said that for app development he does not find kotlin relevant and after google announced he has now started learning kotlin.
