C#, JS, SQL, and (AB) PLC Ladder Logic.
I really like working in the dotnet ecosystem; it's well maintained and supported. I'm fairly weak in JS and find it a bit frustrating at times. Mostly because it seems that packages are obsolete or abandoned by the time I'm done reading the docs. I know enough SQL to be dangerous.
Everyone seems to like Rust, maybe I should see what all the fuss is about.
I can't find it now, but I saw a clip of the CEO being asked about the cobbled together nature of it. He laughed it off saying only the hull was important, and anything else could fail and it would still be safe.
I wonder what he's thinking now...
