I find it useful to frontload my terminals with context about my environment; You wouldn’t want to deploy to the wrong environment now would you?

MermaidJS is great because it brings graphs-as-code to the web! No longer do we need to run graphviz from the commandline to generate static image files each time we make a change; Now we see changes instantly, embed graphs with ease in source repositories and track their changes, etc..

Collaborative websites need to be forked, but if you set a hostname variable, such as
baseURL in Hugo, the forked website will load resources from the original.. Not ideal.
The fix I applied to my GitHub Actions CI to work around this:Read more →

This is my
.vimrc, I find it benefitial to use this where I do development to normalise my editor across different operating systems, and to enable some useful untapped features to make Vim feel a bit less prehistoric.
