There was a serious security hole affecting ruby on rails announced the the other day, and this blog was affected. It was also affected by hundreds of other security holes, since I hadn’t upgraded my blog engine, typo, since 2006. :)
Since attackers could have executed arbitrary ruby code on my shared hosting instance, I decided it was time do something, so I checked out a comparison site, discovered that octopress is the most popular ruby blogging system these days, and decided to switch. So far so good; thanks for the migration tools, octopress!
