I now added a feed for my hacks page, feel free to subscribe with your feedreader: https://phala.isatty.net/~amber/hacks/index.atom.
Thanks to XML::Atom::SimpleFeed this was quite easy. No full text in the feed yet, sorry.
Previous iterations of the index page simply ordered all POD articles by mtime, but I now added an explicit list of published articles. This means I can just write a new article, and it only ends up in the overview page and the feed when I add it to a list of published articles.
