Recent improvements to the ClojureScript compiler have greatly simplified setting up development versus production outputs.

This example uses Figwheel as something that you want to exclude for production, but the pattern is general.

With this simple setup you only need one html file/view and it will work for developement and production.

Overview

Internet connection and DNS routing are broken from WSL2 instances, when some VPNs are active.

The root cause seems to be that WSL2 and the VPN use the same IP address block, and the VPN routing clobbers WSL2's network routing.

This problem is tracked in multiple microsoft/WSL issues including, but not limited to:

• microsoft/WSL#5068
• microsoft/WSL#4277

Rich Already Answered That!

A list of commonly asked questions, design decisions, reasons why Clojure is the way it is as they were answered directly by Rich (even when from many years ago, those answers are pretty much valid today!). Feel free to point friends and colleagues here next time they ask (again). Answers are pasted verbatim (I've made small adjustments for readibility, but never changed a sentence) from mailing lists, articles, chats.

How to use:
