Project mention: A statement about my Scala open source work | reddit.com/r/programming | 2021-11-18
The first point is about a fucking conference in 2016, in which the organizer invited several people with a process (and thoughts) explained here https://degoes.net/articles/lambdaconf-controversy aimed at being blind to sex/religion/political views etc. He repeatedly stated to be in a strong disagreement with "white supremacist" views and the such. The first words of the ZIO's code of conduct are precisely about that btw https://github.com/zio/zio/blob/master/docs/about/code_of_conduct.md, and zio follows the scala code of conduct. You can agree or disagree about whether "allowing that person, selected in the way described above (without any preference at all for white supremacists of course), to speak precisely about one particular topic and only if they adhere to the code of conduct" is "giving them a platform to share their ideas", but even if you do think that the first approach is completely wrong, it's a pretty big jump from here to accuse the person holding that view (actually a less-strong version of it) of being a white supremacist themselves and the same of all people that associate with that person (the organizer) and stalk and harass them for years on end

Project mention: Endless4s: a new Scala library to describe event sourced entities using tagless-final algebras, running with built-in implementations for Akka | reddit.com/r/scala | 2021-12-06
https://endless4s.github.io Endless bridges the gap between Cats Effect and Akka Cluster Sharding. It makes it possible to define abstract repository and entity algebras in tagless-final style to describe distributed event sourced domains seamlessly within functional codebases. I'm exited about it, let me know what you think!

OPS
OPS - Build and Run Open Source Unikernels. Quickly and easily build and deploy open source unikernels in tens of seconds. Deploy in any language to any cloud.

Note: I believe tofu-optics uses a profunctor encoding under the hood which let them side steps some type inference issues. Better to check with Odomontois.

Project mention: Effekt, a research language with effect handlers and lightweight polymorphism | news.ycombinator.com | 2021-11-19
How does this compare to other effect-oriented languages like Koka, Frank, and Eff?
I've been doing some work with Koka lately, but I briefly looked into the other three (including Effekt) and it mostly came down to, 'Koka seems most active in development'[1] and 'Koka had the easiest to use documentation for me'[2].
[1] E.g. https://github.com/effekt-lang/effekt had its last commit back in June; https://github.com/frank-lang/frank last commit last year; but https://github.com/koka-lang/koka last update was Oct 15. Effekt seems semi-active, at least, compared to Frank. While stability is good, I wouldn't expect it in a language actively being used for research.
