ab, Apache Bench, is often used to load test websites, but I didn’t find it extensible enough for my needs. Unless an unofficial patch is applied, it cannot attempt to simulate a real person by going to random URLs. This is where siege comes in.

In a previous post, I described a method to inject content into a Jekyll post. The method worked but felt hacky and inelegant. Additionally, you could only inject content one time in a Jekyll post.

Debian/Ubuntu’s Preseed is not the easiest thing to understand. Having used Red Hat/CentOS Kickstart Profiles for so long, trying to setup a Preseed file for the first time was an extremely uninviting process.
