Clojure Deref (Sept 3, 2021)

Welcome to the Clojure Deref! This is a weekly link/news roundup for the Clojure ecosystem. (@ClojureDeref RSS)


Clojurists Together announced their Q3 funding projects - congrats to all receiving funding and thanks to Clojurists Together for facilitating the funding of open source! I don’t know of any other language community that does as much as the Clojure community to support sustainable open source.

If you like learning things, two things to mention this week - Jacek Schae opened the Learn Datomic course for enrollment and Deep Learning for Programmers by Dragan Djuric finally hit 1.0.0! Dig in and learn something new!

In the core

I think both Fogus and I continued working on the same things we’ve been working on the last couple weeks but moving asymptotically closer to "finished". We also did a lot of updates on various Clojure JIRA tickets, preparing things for Rich to look at. We are expecting to move some of this work (lightweight keyword aliasing, update-keys, update-vals, bunch of jiras) over the line and into a Clojure 1.11.0-alpha2 over the next week. Not sure yet exactly what that will include, depends what makes it through review, some may slip out of alpha2, but I think we will have enough to get an alpha2 out regardless. A lot of what we have been working on is really revising how we work so that we can more regularly deliver new Clojure goodness to you!

This week also saw the release of a new Clojure CLI version, which is largely the same but bumps all of the transitive deps (importantly including some transitive dep security updates and Maven download concurrency improvements), and replaces our build process for the CLI itself with, so we are eating our dogfood there (and it tastes pretty good!). I did fix a few minor issues in tools.deps and through that process, but things went surprisingly smoothly.

Video Throwback

I’m very happy this week to release a new edit of "Simple Made Easy" by Rich Hickey, which was first given as the closing keynote at Strange Loop 2011, 10 years ago. To make this edit, I used the original HD video and Rich’s original slides with all the bullet/slide transitions and animations, so this is as close as you’ll get to how it was originally given in the room. Enjoy this classic!
