Strong static typing. I “enjoy” erlang and elixir more (erlang syntax more, elixir metaprogramming more, both of the actor model), but the lack of strong static (especially static) typing part really makes me code a lot more buggy in it then in something like Rust, where if it compiles then it’s generally bugless. Gleam is interesting but it’s also missing the vast rust library ecosystem too.
Yeah Discourse is extremely connection heavy, which is “fine’ish” on http2, but still inefficient because it doesn’t preload them via http2, rather a lot are serialized based on things getting run and asking for more stuff… If discourse actually used HTTP2’s preloading effectively then it would make a world of difference.
