Okay. Let's pretend here for a sec that you work in an office where UDP is filtered outbound, but we really want to use UDP for mosh.

Here's the plan at a high level.

1. Spin up a cloud server
2. Install Docker
3. Start OpenVPN Container
4. Grab .ovpn config
5. Modify .ovpn config to a include static route to your UDP-enabled destination

- you add and commit with the wrong email address in git, and
- your remote has a hook set up to prevent you from pushing with the bad address

Then you need to amend the author of your commit before push can succeed:

$ git config user.name "Your Name"

One-line Tree in Python

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

// This example shows how to render pages that perform AJAX calls
// upon page load.
//
// Instead of waiting a fixed amount of time before doing the render,
// we are keeping track of every resource that is loaded.
//
// Once all resources are loaded, we wait a small amount of time
// (resourceWait) in case these resources load other resources.
//
// The page is rendered after a maximum amount of time (maxRenderTime)
