Working Notes

The actual lab went smoothly. I had to, among other things, set up a Wordpress blog using Docker Compose within a network of Virtual Machines. The only issue I encountered was with the VM setup itself - I use a particular Windows Server VM as the management hub for the network, but it only has Internet Explorer installed as a browser. Internet Explorer, being the buggy, insecure, out-of-date mess that it is, didn't play nice with Wordpress, so I had to access it from a different VM. No big deal, all things considered.

Journaling

Journaling was a nightmare, because I decided to start work on making a more consistent wiki, in terms of both page names and styling. Aside from renaming around a third of the files in the wiki, I updated the sidebar and footer, with the intention of using relative links, but managed to completely break most of the links, through an overzealous pattern substitution in GVIM (:0,54s/h.*wiki\///g), but didn't notice until after committing to the wiki. After fixing it, I noticed that seemingly random links in the Sidebar/Footer (both are identical) weren't working, because it seems that colons within markdown links worked when using the absolute paths to access them, but not the relative paths, so I had to replace every instance of a colon in the links with "%3A". After using another overzealous pattern substitution, but catching and undoing it immediately, I was able to fix it, but now, as of writing this, I'm guessing that most links to pages on this wiki are broken. I intend to fix them, but there are more renames that I need to do.
