The favicon is LEGO part #2435. As a child was fascinated with the larger LEGO tree as a manufactured object. I also spent a lot of time in forests and many of my friends were trees. (I used to use the Unicode tree glyph as a logo of sorts, but it has been lost to creeping emojification.)
Search is kept local thanks to lunr.
When I publish to a specific git branch, Travis CI builds the site and deploys to Amazon S3. Cloudfront serves it to you.
One of the ways I publish is with Sitewriter.
Type is served by the Font Library.
Google Analytics is used for usage tracking and may drop a cookie on you. I’ve set my account to not share tracking data, but you have no way to validate that and I have no way to confirm that Google honors this setting. I plan to replace this with direct log analysis.
Other external resources are referenced, including Twitter’s scripts for explicit pop-ups and jQuery from their CDN. On the homepage a Flickr script is loaded which insists on loading a Yahoo geolocation script as well as requested assets. None of these should be using this to track you, but my control is limited so YMMV.
The site history page provides background.
