Local SSL websites on macOS Sierra

These instructions will guide you through the process of setting up local, trusted websites on your own computer.

These instructions are intended to be used on macOS Sierra, but they have been known to work in El Capitan, Yosemite, Mavericks, and Mountain Lion.

NOTE: You may substitute the edit command for nano, vim, or whatever the editor of your choice is. Personally, I forward the edit command to Sublime Text:

alias edit="/Applications/Sublime\ Text.app/Contents/SharedSupport/bin/subl"

Configure Git to use a proxy

In Brief

You may need to configure a proxy server if you're having trouble cloning or fetching from a remote repository or getting an error like unable to access '...' Couldn't resolve host '...'.

Consider something like:

merolhack

function slugify(text) 
{
    var from = "ãàáäâẽèéëêìíïîõòóöôùúüûñç·/_,:;";
    var to   = "aaaaaeeeeeiiiiooooouuuunc------";
    _.each( from, function( character, i ) {
        text = text.replace(new RegExp(from.charAt(i), 'g'), to.charAt(i));
    });
    return text
        .toString()                     // Cast to string
        .toLowerCase()                  // Convert the string to lowercase letters

veltman

Tweening between one and many polygons with an approach that's faster and more robust than this Voronoi jigsaw attempt.

This approach uses earcut and some artisanal TopoJSON to triangulate the polygon and successively merge the triangles into the desired number of pieces, and then adds/rewinds points for smoother transitions (see this demo for a better look at what's happening behind the scenes).
