Finally I got rid of the plain-jane Ghost theme and replaced it with a custom made one by my brother, Marian Friedmann. In the course of the release of the redesign, I also switched from Ghost back to a static site generator called metalsmith to run this blog.
Now why is that, you ask? Well, I already wrote about the advantages of SSGs over dynamic driven blogs three years ago in my very first blog post. Give it a read if you are interested in the recent decision.
Last but not least, I pushed the complete source code of this blog (including the posts itself) to GitHub. Feel free to send a pull request in case you found a typo or mistake and if you're willing to contribute!
