Occasionally people ask me why there is no comment function on this blog. There are two answers for that: First, the software I use to create this blog does not support comments. My blog posts are “compiled” into static web pages that I then upload to my public site. This has many advantages. The site is fast, I don’t need a database around, the files are easy to backup and can be kept under version control. But mainly it means I can sleep soundly, because I don’t have to update Wordpress or some other blogging software every time a new security vulnerability is found.
