Hey, new release of rsocket-kotlin is here! 0.14.3 brings support for fragmentation, improved transport API and kotlin 1.6.10. Available on Maven Central! Stay tuned, as future releases will contain support for Resumption, Leasing (Request limiting) and experimental QUIC support on JVM via Netty QUIC codec! Release Notes | Changelog

After almost a year being a draft, the article about problems with plugin model in Gradle is out: https://medium.com/@altavir/what-is-wrong-with-gradle-a312a7ceb651. It is complementary to the talk I've made here (I hope that the recording will be available soon). In the talk I explain why Gradle is unique in its flexibility, but there are some problems. The article mostly about global design, but is based mostly on gradle.kts.

TL;DR I have created a script that would let you try out small snippet of Kotlin code from the terminal. So, you don't have to launch

intelliJ

to try out simple Kotlin code. I would like to know how you are trying out simple Kotlin code? Would you like to use the script? Or create one? One thing I love about interpreted languages line Python is being able to try out a code snippet directly from the command line. In Python, you can either use the interactive shell or save it in a

.py

file and run it using

python script.py

. However, when it comes to Kotlin the scenario is hugely different. Most of the times I have to launch

intelliJ

to understand the behaviour of a simple code. And launching an IDE is no joke. It takes a lot of time for starting and indexing. And if any extra dependency is needed we have to initialise a Gradle project for that. The web based Kotlin Playground is more convenient. But sadly we can't add any third party dependencies there. I have always wanted something that would allow us to run a

.kt

file from the command line. But I couldn't find something like that. But today I wrote a

python

script that allows me to run a Kotlin file from the command line. For example, Create a file with

.kt

extension and write some code in it.

// filename -> app.kt

fun main(){
    println("Hello, world")
}

Then in the terminal type this,

>> kotlin app.kt

Hello, world // the output

I would like to know how you are trying out small snippets of Kotlin code. Would you be interested in a tutorial that would show you how to create this kind of script? Let me know 🙂

Hey everyone 👋 While working at different places on different projects its always been interesting how developers choose to go about creating models for unit tests. I’ve seen some projects redundantly create new models for each and every test, and some projects create factories, with static models that they then use everywhere. Long story short, at work we wanted to clean up some of these tests so two of us started working on a library that would automat this for us and generate random models with actual data. The fruits of our labor can be found below 🤓 We have been using it in production for about 6 months now 🚀 We would be eternally grateful for any feedback you might have 🙏 and to see wether it potentially fits your use cases as well. Please take a look, try it out and let us know what you think 🙌 Collaboration welcome 👩‍💻 👨‍💻 https://github.com/HelloCuriosity/model-forge

Hi, I have written the next part of my Coroutines series: https://maxkim.eu/things-every-kotlin-developer-should-know-about-coroutines-part-3-structured-concurrency

Hi all, I published new article about multi module architecture. I waiting for your feedbacks. https://talhafaki05.medium.com/what-is-multi-module-arch-7fe0eca2fff8

Since I was intrigued by this for quite some time already, I analyzed almost 40 of Kotlin's features and language constructs (which are probably almost all there are) to see how each ends up looking when compiled to run on the JVM as the target platform (which of course is the most common target still)! Since byte-code is pretty tedious to read, I created an example for each, compiled that into JVM byte-code and then decompiled it again into Java to have a more or less close look at what the results are. This is of course not 100% accurate but for most features the output is pretty clear. I produced a video looking at the most interesting ones and discussing them:

:kotlin-intensifies-purple: Additionally, I published all of the examples in a repository: https://github.com/The-Self-Taught-Software-Engineer/kotlin-decompiled

There's been another surge of questions regarding Kotlin/JS interop recently so I went ahead and summed up what I've learned throughout the years in an article. Hope it helps the Kotlin/JS adoption!

Finally, I finished the first part of the KMM project. I finished MVP application for android on Jetpack Compose. As a result, there are 5 libraries that can help Android developers with Jetpack Compose for their applications. • Compose Routing - Systematization and navigation • Compose Forms - Systematization, validation, custom fields • Compose Modifier Extension - Extensions for modifier • Compose Requests - Handling requests and states for Jetpack compose • KeyGenQt Accompanist - Custom features for Jetpack compose The project is here. Thank you for your attention. Happy New Year!

Hello, is jcenter officially dead? I thought it should've been supported until the 1st of february, but I get 502 https://jcenter.bintray.com/. Now my gradle sync won't work, even if I replace the repositories with maven central, it will still try to download

gradle-kotlin-dsl-plugins

from jcenter
