Because contents of this blog are stored in a git repository you can just
git clone --verbose --recursive https://gitlab.com/xgqt/blog
then, read the "raw" ORG files in 'posts' directory or make the HTML version executing the 'dev.sh' script (remember that you will need GNU Emacs to render the posts into HTML files).
Then, you can just git pull to read the news whenever you wish, maybe do it with cron or a script that will pull many repos at once, for example with this script.
Org-Static-Blog creates a RSS Feed file
rss.xml, so to subscribe add the link https://xgqt.gitlab.io/blog/rss.xml to your favorite RSS reader.
You can also subscribe to the GitLab repository Atom feed.
