• The biggest ‘wow’ article for me this week was Pyroclast, an in browser simulation tool for an Onyx cluster. It looks like it could speed up iteration by a factor of 10-1000x.
• The 2016 State of Clojure survey has been released
• I wrote an analysis of the free text survey question
• Building a Chrome extension with ClojureScript - Hacker News Lookup
• Clojure memory leaks in production (spoiler, it was memoize)
• There are some cool project ideas for the Clojure Google Summer of Code 2017 program (Clojure hasn’t been accepted yet).

Libraries & Books.

• serverless-cljs
• Mozilla has renamed datomish, their Datomic inspired store to mentat
• toucan: A (classy) Clojure ORM from Metabase

People are worried about Types. ?

• There was plenty of type worrying (but maybe less than last year?) in the Clojure Survey responses.

Foundations.

• The always excellent Dan Luu on web bloat
• A Jepsen test of MongoDB by Kyle Kingsbury. I award no points for guessing that Mongo’s first  (and still in use) replication protocol turned out to be “intrinsically unsafe”
• Java 9 will change the way you traverse stack traces. Maybe it will change the way we traverse Clojure ones too?

Tools.

• calvin: A minimalistic CLJS build tool which doesn’t require a JVM (!)
• Faster Meta-development with Boot by Alan Dipert with a demonstration of how to avoid needing to restart Clojure programs in development.
• Vim turns 25 and releases Vim 8
• Provisioning Datomic using Packer and Terraform

Recent Developments.

• CLJ-1496: Add a new arity to ex-info that only accepts a message
• CLJ-1776: Test that collections are valid statements

Learning.

• Functions Explained Through Patterns

Misc.

• Aesthetic Engine 2 provides an abstract visualisation of webpages. I learnt a new-to-me term “Data Dramatisation” too.
