Notes.

It’s been a busy month or so with travel to family, but The REPL is back this week.

-main

• Datomic has released a new feature: Ions. This is a way to run functions on your Datomic Cloud cluster.
• I’ve been really excited to follow cljdoc, a new Clojure documentation project

Libraries & Books.

• Zach Tellman talks more about his Elements of Clojure book
• nREPL has completed its migration to a new project on GitHub

People are worried about Types. ?

• Robust Clojure: The best way to handle nil, and HN comments

Foundations.

• Oracle plans to disable risky Java object serialisation in the future
• Java Mission Control was recently open sourced, but sadly most of the team was laid off last week.

Tools.

• Lexikon lets you manipulate and replay your lexical environment, similarly to scope-capture
• crossclj is now open source
• Reid McKenzie on Pants, Bazel, and Clojure cross project builds

Recent Developments.

• CLJ-2350: Improve error message when calling a keyword with the wrong number of arguments

Learning.

• Zach Tellman’s Clojure SYNC talk is up now
• The final Tellman link: Is = fast in Clojure?
• Building a datalog

Misc.

• CHECK_RARE and making sense of unusual occurences. This was a neat post. I like the idea of using something one step above asserts for things that should be extremely rare, but can occasionally occur.
