Here[1] is a nice breakdown of Zippers in Clojure. I am not the author of the post but I found it very helpful when I wanted to learn more about Zippers in Clojure. There are some nice illustrations as well.
mruby[1] fits that category too. It can be used with H2O[2] server as well. There was a discussion here a couple of months ago regarding some use cases[3].
When I started using Paredit I found "The Animated Guide to Paredit"[1] very helpful. It basicaly demonastrates some of the most useful commands in short videos.

I follow the same approach. Emacs, Verb[0] and org-mode. An alternative to Verb would be restclient.el[1] but I like Verb more because it works as an extension to org-mode which is great for documentation.
No news about Ractors! The new concurrency facilities that Ruby 3.0 introduced. Anyone has an insight if there was any further development on that front?
That's very interesting! It seems that big Ruby shops like Shopify and Stripe are investing a lot on improving Ruby's performance. Here is a tweet from Stripe's CEO regarding the performance of their custom Ruby compiler https://twitter.com/patrickc/status/1410269843585069056?lang...
One thing that I would like to mention as a Clojure newbie is the community. I am super impressed by how much friendly they are. I mainly use /r/clojure on Reddit and the Clojurians on Slack.
