In trying to improve SEO and users’ ability to find articles on related topics, I split the articles archive into a hierarchy based on categories and tags.
Since there’s no way to write a regular expression to transform URLs starting with /articles to multiple categories, there was the likelihood that I would miss some. And you have tripped over one of the articles that I overlooked and did not write a redirection for. That’s why you’ve arrived at this page.
At this point, the best thing to try is to search this site for the title of the article you are interested in.
I’m sorry for any inconvenience this may have caused you.
