Old vs. new proposed North Carolina congressional districts, data via WRAL.

Polygons were pre-processed for gentler animation as follows:

1. For each district, find the difference n in the number of vertices between the old and new district.
2. Add n vertices to whichever one has fewer, evenly spaced along the existing polyline, so the old and new shape each have the same number of vertices (not great for performance).
3. For each pair of old/new district, wind the old district around to minimize the sum of the squared distances between point index i in the old district and point index i in the new district.

Combining two git repositories

Use case: You have repository A with remote location rA, and repository B (which may or may not have remote location rB). You want to do one of two things:

• preserve all commits of both repositories, but replace everything from A with the contents of B, and use rA as your remote location
• actually combine the two repositories, as if they are two branches that you want to merge, using rA as the remote location

NB: Check out git subtree/git submodule and this Stack Overflow question before going through the steps below. This gist is just a record of how I solved this problem on my own one day.

Before starting, make sure your local and remote repositories are up-to-date with all changes you need. The following steps use the general idea of changing the remote origin and renaming the local master branch of one of the repos in order to combine the two master branches.
