I've dedicated my free time last week to improving this website. I made it myself from scratch more than 10 years ago, using some old version of PHP, MySQL, and HTML 4.01, so it definitely needed some refresh. I introduced many changes to the code, most notably:
I switched to HTML5 and made the website mobile-friendy. There is no separate mobile version. Everything (like font size) should now automatically scale to fit small screen resolutions. Main Page no longer has two-column layout on small screens. Elements of the page overflow nicely thanks to using <div> instead of <table> and applying rules of "responsive design". By the way, I also limited maximum width of the page to make it more convenient to read on big screens.
I installed external service for comments support: Disqus. Now it is more convenient to post comments. You can still post anonymously, or you can login using Disqus, Facebook, Twitter, or Google. Hopefully I will get less spam than I had in recent years in my custom comment system. Unfortunately all the previous comments are lost. I'm sorry for that.
There are still things to do. The website, as well as database, still uses ISO-8859-2 codepage instead of UTF-8 (it was a standard for encoding Polish characters before Unicode became popular). The scripts still generate the page using lots of print()-s instead of some template system. But maybe I will fix that next time :)
