I then have implemented onSensorChanged(), onResume(),...

How to avoid using Kotlin Coroutines' GlobalScope in a Spring WebFlux controller that performs long-running computations I have a Rest API that is implemented using Spring WebFlux and Kotlin with an endpoint that is used to start a long running computation. As it's not really elegant to just let the caller wait until the computation is done, it should immediately return an ID which the caller can use to fetch the result on a different endpoint once it's available. The computation is started in the background and should just complete whenever it's ready - I don't really care about when exactly it's done, as it's...

Split list into groups based on predicate in kotlin Given for example the following : val l = listOf(1, 2, 2, 2, 2, 1, 1, 1, 2, 2), I'd like to have l2 = [ [1], [2, 2, 2, 2], [1, 1, 1], [2, 2]]. I'd accept something in the lines of l2 = [ (1, 1), (2, 4), (1, 3), (2, 2)], whichever is the fastest to achieve. Separating the lists into groups should be based on a predicate ( a function taking a value and returning a boolean). I've been looking into the cleanest way to split a list into groups based on predicate in kotlin. I've found quite a few...
