Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Reactive Backend Applications with Spring Boot, Kotlin and Coroutines (Part 2)
Kotlin has coroutines that are supported by the language and implemented by a library (the implementation remains platform-dependent): kotlinx.coroutines and a sandbox environment is available here to try it out.
- Kotlinx Coroutines for Kotlin 1.7.x

Why no one recommends the use of the standard library's Result class but a custom sealed class approach?
Sure! runCatching catches Throwable right? Well when you cancel a coroutine it throws a CancellationException and this gets used as a signal to stop execution. runCatching stops that signal so the coroutine keeps running. Lemme find you a link real quick https://github.com/Kotlin/kotlinx.coroutines/issues/1814

Is there thread switching when moving from Default dispatcher to IO dispatcher using withContext?
According to the author of kotlinx.coroutines lib, it will try to keep the same thread if possible but not always. After my question, he updated the document of Dispatchers.IO to be like this https://github.com/Kotlin/kotlinx.coroutines/pull/3236/files This dispatcher and its views share threads with the [Default][Dispatchers.Default] dispatcher, so using `withContext(Dispatchers.IO) { ... }` when already running on the [Default][Dispatchers.Default] dispatcher typically does not lead to an actual switching to another thread. In such scenarios, the underlying implementation attempts to keep the execution on the same thread on a best-effort basis.
I think it is a great question and you can ask it on github
This is the issue I posted in GitHub https://github.com/Kotlin/kotlinx.coroutines/issues/3234 Thank you for the suggestion

Am I on the right track?
DI: Dependency injection: Check out Dagger Hilt, Koin or Kodine. Architecture: Android tends to be MVVM but, MVP, MVI and some others exist. Async calls: For kotlin, coroutines. Rxjava can be used with kotlin or java. I'm not actually sure how java devs do asyn calls these days.

Java Virtual Threads Preview
Interestingly, Kotlin Coroutines have been available and in production for a LONG time now.
https://github.com/Kotlin/kotlinx.coroutines
In fact, Kotlin Coroutines are an brilliant on the android platform. We are talking severely memory and CPU constrained architectures here.
That said, Kotlin Coroutines are popularly used in production on server side - https://vertx.io/docs/vertx-lang-kotlin-coroutines/kotlin/
So here's the thing - I would doubt anyone would switch to Java Virtual Threads anytime soon.

Need Help Testing Callback Style Code with Coroutines
Anyways, it seems like it's a common enough issue that it is getting the attention of the kotlin team. I have high hopes for this PR that looks like it might be close to merging, and has activity within the last couple of days.

Build your own curl in Golang
In this tutorial, we'll walk through the process of creating a simple command-line tool similar to curl using Go and Cobra, a CLI library for Go.

Scripts should be written using the project main language
I use https://github.com/spf13/cobra religiously for this kind of thing - it handles all the annoying corner cases of parsing flags, and also has an intuitive notion of subcommands (with basic usage/help text generated) for picking which task you want to run with positional arguments.

Command Line Interface Guidelines
We recently chose cobra[1] to create a cli application. It comes with so many best practices already packaged like autocompletions, help texts etc. etc.

Auto-Completion and Cocktail mixing with Golang’s Cobra CLI
Cobra is a library for creating powerful modern CLI applications. https://github.com/spf13/cobra
In this post we explain how to implement custom auto-completion ability for a CLI tool written in Go and using Cobra. We start by walking through the creation of a tiny mixologist app using Cobra. The mixologist app is a CLI tool written in Go using the Cobra framework that can make cocktails from a list of ingredients and uses custom auto-completion to improve the user experience. For reference, the code for the CLI application can be found here: https://github.com/rafttio/mixologist
