Finally I managed to update my server, but I had a problem: podwiki didn’t run anymore and I also wanted to get rid of django, because operating one website with two content systems is just mad.
Since I do not provide anything interactive anymore, no comments, no forms, no search etc, I don’t really need a content management system either. So this page is now static, simple and it does the job.
I’m using Jekyll to generate the content from text files. To serve pod files with Pod I wrote a small jekyll plugin to render them so that I can convert time during the next weeks if I feel the need. You can find the plugin here, if you’re curious.
