  • Modern Async Primitives on iOS, Android, and the Web

    Kotlin also has a construct for asynchronous collections/streams. Kotlin's version of AsyncSequence is called a Flow. Just as Swift's AsyncSequence builds upon prior experience with RxSwift and Combine, Kotlin's Flow APIs build upon earlier stream/collection APIs in the JVM ecosystem: Java's RxJava, Java8 Streams, Project Reactor, and Scala's Akka.
  • What are the current hot topics in type theory and static analysis?
    15 projects | /r/ProgrammingLanguages | 8 May 2023
    First-class distributed and multicore computing. Swift has first-class “actors” and “distributed” methods. Unison, Erlang, and Elixir are built with distributed being one of the #1 concerns. Though first-class is not super common and I don't really expect it to be because usually libraries are enough (e.g. Scala has Akka and is used WIDELY for distributed); whereas something like linear types and typed effects, you can't emulate in a library.
  • Anything close beam/otp for other languages?
    7 projects | /r/elixir | 7 Apr 2023
    Akka is a library that implements the actor model for JVM languages. Mainly in Scala, but you can use it in Java too, and maybe others. It doesn't feel as ergonomic as Elixir, but if Elixir is too "out there" for the decision makers in your case, this might be a friendlier alternative.

    Note Akka, the Java & friends framework, is working with the actor model and have as main inspiration Erlang to mimic some features of the BEAM on top of the JVM.
  • Akka will no longer be Open Source
    2 projects | dev.to | 10 Sep 2022
    If I hear about Actor model, the first thing that comes to my mind is the popular Open Source library Akka.

    Lightbend, the company owning Akka, recently shared a blog post signed by the CEO announcing a license change from Apache 2.0 to Business Source License 1.1, a proprietary license. You can already find it in this PR, merged a couple days ago.
  • Why We Are Changing the License for Akka
    2 projects | /r/scala | 7 Sep 2022
    Akka 2.6 is on the open source Apache license, that is unchanged (its not possible for Lightbend to change an existing license). Its only the new Akka 2.7 which has the BSL license, so as long as you don't upgrade you are fine. See https://github.com/akka/akka/pull/31561.

    Here is Akka's dependency specification: https://github.com/akka/akka/blob/main/project/Dependencies....

    How many of these would have to opt for this source available approach before Akka would no longer be sustainable?

    I don't think that the Akka change is aimed at cloud providers. Akka is a toolkit for building highly concurrent, distributed, and resilient message-driven applications for Java and Scala [1]. It's not possible for AWS to offer their own "Akka service" the way they offered Redis through ElastiCache. This change affects companies that build software using Akka, many of which may not be software-focused. For example, here's a case study of an oilfield services company that uses Akka:

    That largely depends on the type system. Languages like Haskell and Scala which have much more powerful type systems than C/Java/Go/etc absolutely do allow you to do those sorts of things. It is a bit harder to wrap your head around to be sure and there are some rough edges, but once you get the hang of it you can get the benefits of static typing with the flexibility of dynamic typing. See https://github.com/milessabin/shapeless or a project that I've been working on a lot lately https://github.com/zio/zio-schema.
  • Scala3: Does it provide a simplified way of doing n-term generic parameters?
    2 projects | /r/scala | 6 Jun 2021
    Just use cats and use the apply syntax .mapN for this. Seriously. There isn't a way to do it without generating source code that I can see in the api. Scala 3's HList Tuples aren't like Shapeless 2's HLists and I can't figure out a way in the api to reduce the tuple members down from (A, B, C, D) into an E, generically, yet with Scala 3 poly functions, unlike what you could do in Shapeless 2 with HList
  • Scala: A Love Story
    4 projects | dev.to | 21 Apr 2021
    Scala has sparked a huge ecosystem of very high quality libraries (Cats, Scalaz, shapeless, to name but a few). I think a major reason for this is that Scala attracts developers who value the advantages of the JVM, but are fed up with the limitations of the Java programming language and understand the benefits of an expressive type system and functional programming.

    I also investigated shapeless3 macroses: https://github.com/milessabin/shapeless/tree/shapeless-3/modules, but they are more about derivation than reflection. And probably that is all I found.
  • Why Learn Haskell?
    2 projects | news.ycombinator.com | 1 Mar 2021
    I'm not sure where is the line between extensive and basic knowledge. Here is my more detailed exposure:

    In commercial context:

    * Of strongly typed ones only Scala (with [shapeless]). Can reluctantly throw in Kotlin as well for it's amazing structured concurrency.

    In non-commercial context:

    * Went through a few chapters of [Software Foundations] doing Coq proofs.

    * Worked through most of the [Types and Programming Languages] (writing typecheckers in Ocaml)

    * 3 services in Haskell (1 on Scotty, 2 on Servant). Loved persistent+esqueleto for the ORM layer, disliked Opaleye.

    * 2 projects in PureScript (1 with Halogen, 1 with React bindings).

    * 1 project in ReasonML (Ocaml).

    > I am afraid there is no way back for me

    I see where you are coming from. In my case I can alternate between "I want all invariants properly expressed and checked" and "I just want to ship that barely-working piece of junk and iterate on it". I learned to adjust depending on organization needs. IMO, for many orgs, especially startups/scaleups, the latter is often the more fitting way. With that in mind, I'm willing to trade the guiding hand of great type systems for other productivity aspects (amazing runtime and cohesive web framework in Elixir's case).
