A 'Game of Thrones' Maths Puzzle

Four prisoners escape from the dungeons at King's Landing and head for the Wall; a distance of 700 leagues. The Maester travels 1 league in the first day, then each subsequent day, doubles the distance he travelled the previous day. The Whore travels 50 leagues each day.

The dates are approximate, generally the year that version was last used before I changed to the next one. The earlier versions I got from static HTML files I have backed up on my computer, the rest were from the Wayback Machine.

Creating a GitHub-like editing experience in Backdrop

I'm a big fan of the editing experience in GitHub. Through using GitHub over the last few years for my contributions to various open-source projects (mainly Backdrop CMS), I've learnt to write posts in Markdown and love the way GitHub makes it easy to add syntax-highlighted code snippets, insert images, etc. I wanted to replicate some of that functionality in Backdrop, so here's what I did...
