Forget that you’re developer, go to school and learn how to understand your team, empathy, leading, managing. Also find a good psychotherapist 🙂

Hello, have someone any experience with React Native & Kotlin ? #javascript

Um, when I refactor to change signature in IntelliJ and switch a parameter to a property, there's no space between the

val

and my name. Is this just me?

Haskell generally has a more complete type system in that I believe that it’s possible to express some concepts that can’t be expressed with Kotlin’s type system (ie. the specific return type of the y-combinator). It also has support for type intersections and unions, which are missing from Kotlin, but which can be handled with some verbose options. Ceylon is also a JVM language which has a slightly better type system than Kotlin (unions and intersections, and Ceylon’s nullable types are derived from unions I believe).

❓ Is this valid Kotlin code?

{->}.fun 
Function<*>.(){}()

Do you know of any validation framework with Kotlin-friendly APIs? Or maybe someone wants to make one?

val name = expression.validate {
   … some validation clauses…
}

So that there could be range checks, nullity, etc. I didn’t put any thought into it yet, but I feel the need in many places.

maybe this isn’t really the right approach within Kotlin, but is there any provision for validating data class constructor arguments?

where?

Are there any solid possible reason why one would want to start a new project with Java (aside from working on Android and worrying about people not very familiar with Kotlin)

@karelpeeters This is the random channel, and people here tend to have experience with such things, so this is a great place to ask.

Yesterday me and some friends from the university did the Google HashCode 2018 challenge. We wrote the code in python. Today I converted the code to Kotlin, keeping the same algorithm. The python code took 130 seconds to run. The kotlin code took ~880ms.

I'll bite: How would you use this? What the use case?

anyone here is using sealed-class as some sort of advanced enums?

I'm using enum due to ability list all enum items. Or it's also possible in sealed class?

I'm interested into constraining function extensions only to some specific typealias

just wondering if there’s anyway to arrange layout files in android studio

At least, I've always seen the same behavior with Gnome in Fedora and Ubuntu

on windows, when you right click, no matter how long you hold it or where you release the button it will NEVER trigger anything

I wonder where to get all these dependencies from (in their correct version): https://github.com/JetBrains/Grammar-Kit/blob/master/resources/META-INF/MANIFEST.MF#L3-L7

From the twitter thread:

100 people - yay we're all friends
1,000 people - this is a shitshow
10,000 people - nobody is posting anymore because what is the point even

This sort of reflects what I’ve noticed over the last couple of years in this Slack-- in that the slack seems somewhat less active now than when there were fewer people. As for how to fix the problems that are talked about in the tweets, I think a sociologist is required, but I suspect it involves breaking up channels into sub-channels in some way, because having a meaningful conversation in a channel with thousands of people in it doesn’t even make any sense.

I might be missing something, but why would a slack group or a channel become less active when there are more people in it?

Regarding slack, I noticed that I cannot keep up with most channels anymore. Even though there are some interesting discussions in

general

, I don't have the time to read through it anymore.

Is there something like

com.google.common.annotations.VisibleForTesting

without the need of importing guava?

When you don't agree with the naming of your backend guy(s) 😅 :

@JsonSerializable
data class UserInfo(
        @Json(name = "title")
        val civility: String,
        @Json(name = "forename")
        val firstName: String,
        @Json(name = "name")
        val lastName: String,
        val email: String,
        @Json(name = "gsm")
        val mobilePhoneNumber: String,
        @Json(name = "street1")
        val addressFirstLine: String,
        @Json(name = "street2")
        val addressSecondLine: String,
        @Json(name = "zip")
        val postalCode: String,
        val city: String,
        @Json(name = "licence")
        val licenseNumber: String
)
