Question for the nerds, is there any good examples or projects that deal with raw sockets and custom protocols that are not http related? Want to do something more lower level and not sure where to look for good ways to manage the connections and parsers, etc

So, I can't download artifacts from GH actions from curl? It's making creating a PKGBUILD to download the scalafmt native binary from there a nightmare. Also sucks hard that there is no link on the release to the exact artifact and I have no manually match the git commit 🤬.

Oh dear nightmare bed time stories as usual.

Lately I've been trying to package for some tools, especially their native versions. Still ongoing and I don't have much time for it. Eventually I really wanna try full build them instead of copying the binaries from github.

GADTs By Use Cases (ScalaIO 2019 Workshop) [x-post from /r/scala] -

Some ppl: is really smart, they enforced {} in if expressions for example so you don't need to put () around the boolean condition and that really helps in being more clear and simple.

Others: we totally want and deserve to live in a world of pain with full whitespace indents.

Everyone wanting a simpler : I just want to not have to change () into {} when I want to write multiple lines in a map or so.

Mr odersky: i totally understand, here, go get it - - >

One of the few things I know for sure in this world is that once you use a play framework version you ain't gonna update ever again. Unless there's a full time job just for that. Which is obviously good.

This is the "rant" for the week 😀

Pros and cons of using scala 😂. I also always blame java and jvm for its worst 😌.
