MSBuild tip: if you're working with binlogs, set the environment variable MSBuildLogPropertyTracking=15.

It enables logging of where each property was initially assigned from during evaluation and lights up more features in the binlog viewer.
screenshot of MSBuild binlog viewer on the Properties and Items tab, the query shows `$property "OutputPath" "UseArtifactsOutput"` results show a tree where each assignment to OutputPath is highlighted, with the actual value being displayed where an assignment was made

Given the port from Disqus to Gisqus worked so well for my personal website (thanks to @andrewlock.bsky.social! 🙏), I've just done the same for the podcast!

A good time to go and comment on your favorite episodes! 😊

As part of this, I added Giscus for comments instead of Disqus that I was using in the previous version. I haven't ported the old comments yet though.
Just Googled it and found this post (and migration tool!) by @andrewlock.bsky.social!

The new version of my personal website is now live! I've switched from a DIY solution to @11ty.dev (largely "vibe coded"). I wanted the homepage to be a landing page for all my things - rather than being the blog listing page. Thoughts/feedback are greatly appreciated 😊
