Goals: Add links that are reasonable and good explanations of how stuff works. No hype and no vendor content if possible. Practical first-hand accounts of models in prod eagerly sought.

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:
If you're encountering ping github.com
failing inside WSL with a Temporary failure in name resolution
, you're not alone — this has been a long-standing issue, especially when using VPNs or corporate networks.
This issue is now fixed robustly with DNS tunneling, which preserves dynamic DNS behavior and avoids limitations like WSL’s former hard cap of 3 DNS servers in /etc/resolv.conf
.
DNS tunneling is enabled by default in WSL version 2.2.1 and later, meaning that if you're still seeing DNS resolution issues, the first and most effective fix is simply to upgrade WSL. Upgrading WSL updates the WSL platform itself, but does not affect your installed Linux distributions, apps, or files.
To upgrade WSL, follow these steps,
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:
Picking the right architecture = Picking the right battles + Managing trade-offs
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.
