I discovered gitconfig’s includeIf feature can change your global Git config depending on which directory you are working in. This is super useful if you have different identities for different project, or you need to specify the SSH key to use, etc.. in my case I want to use my personal email address for personal projects and work email for work projects. So let’s assume a directory layout like this:...

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..

I’ll list these here so you can get graphing quicker than I did! ...
