• Autochrome’s structural diffs for Clojure source code are very cool. I’ve long wished for something like this.
• Metosin have recently published Retit, a new router for Clojure and ClojureScript. They’ve written about their motivations for creating it, and integrating it with Ring
• Using Clojure macros to clean up error handling
• Replacing the Clojurians Slack log
• How we built Whimsical (with Clojure, ClojureScript, Aleph, reagent, and re-frame)

Libraries & Books.

• Programming Clojure has a 3rd edition out with new sections on transducers and spec.
• Configuron is similar to environ, but reloads changes when your project.clj changes, and has ClojureScript support.
• thorn is a library for detecting homographs (strings that look similar/the same but have different characters). ‘Let’s talk about usernames’ is a good primer on why you’d want to use thorn.
• clj-http-ssrf helps you prevent server side request forgeries when making requests with clj-http

People are worried about Types. ?

• s/valid? does not tell me if the data is valid as supplied, the dangers of using conformers for coercion, and Alex Miller’s strong warning against it.

Tools.

• I’ve been working for quite a while on re-frame-10x (née re-frame-trace) a debugging and inspection tool for re-frame-apps. We announced a major new revamp of it this week, if you use re-frame, I’d highly recommend checking it out.
• TNS-48: Ability to track files that are not namespaces 
• Access control in Datomic Cloud
• Reid McKenzie’s Docs Sketches
• Overview of the nREPL

Recent Developments.

• Why doesn’t Clojure support raw strings?
