Each week, we discuss a different topic about Clojure and functional programming. If you have a question or topic you'd like us to discuss, tweet @clojuredesign, send an email to feedback@clojuredesign.club, or join the #clojuredesign-podcast channel on the Clojurians Slack. This week, the topic is: "what's old is new again". We find ourselves staring at code for the first time—even though we wrote some of it! Our discussion includes: Christoph re-opened his own code base after 14 months! Nate joined a software team with a large, legacy code base. Why does the problem of "fresh eyes" matter s ..read more

This is a summary of the open source work I've spent my time on throughout March and April, 2024. Overall it was a really insightful couple of months for me, with lots of productive discussions and meetings happening among key contributors to Clojure's data science ecosystem and great progress toward some of our most ambitious goals. Sponsors This work is made possible by the generous ongoing support of my sponsors. I appreciate all of the support the community has given to my work and would like to give a special thanks to Clojurists Together and Nubank for providing me with lucrative enough ..read more

Last time I ran a huge experiment trying to figure out how components should work in Humble UI. Since then, I’ve been trying to bring it to the main. This was trickier than I anticipated — even with a working prototype, there are still lots of decisions to make, and each one takes time. I discussed some ideas in Humble Chronicles: Managing State with VDOM, but this is what we ultimately arrived at. The simplest component: (ui/defcomp my-comp [] [ui/label "Hello, world!"]) Note the use of square brackets [], it’s important. We are not creating nodes directly, we return a “description” of UI ..read more

In HumbleUI, there is a full-fledged OOP system that powers lower-level component instances. Sacrilegious, I know, in Clojure we are not supposed to talk about it. But... Look. Components (we call them Nodes in Humble UI because they serve the same purpose as DOM nodes) have state. Plain and simple. No way around it. So we need something stateful to store them. They also have behaviors. Again, pretty unavoidable. State and behavior work together. Still not a case for OOP yet: could’ve been maps and functions. One can just (def node [] {:state (volatile! state) :measure (fn ..read more

It took more than ten years of full-time work for Rama to go from an idea to a production system. I shudder to think of how long it would have taken without Clojure. Rama is a programming platform that integrates and generalizes backend development. Whereas previously backends were built with a hodgepodge of databases, application servers, queues, processing systems, deployment tools, monitoring systems, and more, Rama can build end-to-end backends at any scale on its own in a tiny fraction of the code. At its core is a new programming language implementing a new programming paradigm, at the ..read more
