For a long time you could find Erwin's dusty Wordpress installation here. Then, when he eventually stopped using DreamHost altogether and parked the website in an AWS S3 bucket, it was just a static page with a few links.
Now it has been replaced by something that attempts to strike a balance between the two: Multiple pages for different purposes, but generated once (courtesy of Hugo at this time) and then served up as static content, so that serving it up is about as efficient as it can get (which is just the way he likes it). Originally in that same S3 bucket, later moved to a static website hoster.
At this time you can find something akin to blog posts and a growing list of personal projects.
