Chrome stores .user.js scripts in a .ldb, which isn't in a user accessible format to recovery. On some versions of macOS the provided python script can't compile the leveldb package. As a workaround, we can use the node level package to recover our userscripts.

What forces layout/reflow. The comprehensive list.
All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.
Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

requiring npm modules in the browser console
The final result: require() any module on npm in your browser console with browserify
This article is written to explain how the above gif works in the chrome (and other) browser consoles. A quick disclaimer: this whole thing is a huge hack, it shouldn't be used for anything seriously, and there are probably much better ways of accomplishing the same.
Update: There are much better ways of accomplishing the same, and the script has been updated to use a much simpler method pulling directly from browserify-cdn. See this thread for details: mathisonian/requirify#5

Instructions on how to fix npm if you've installed Node through Homebrew on Mac OS X or Linuxbrew
This entire guide is based on an old version of Homebrew/Node and no longer applies. It was only ever intended to fix a specific error message which has since been fixed. I've kept it here for historical purposes, but it should no longer be used. Homebrew maintainers have fixed things and the options mentioned don't exist and won't work.
I still believe it is better to manually install npm separately since having a generic package manager maintain another package manager is a bad idea, but the instructions below don't explain how to do that.
Installing node through Homebrew can cause problems with npm for globally installed packages. To fix it quickly, use the solution below. An explanation is also included at the end of this document.

Dear Ember.JS team, for your consideration:
We have things like title and draggable natively: attributes that
add behavior to an element. I'd like this ability in ember. It could
work something like this:
App.TooltipDecorator = Ember.Decorator.extend({
tooltipElement: function() {
Locate the section for your github remote in the .git/config file. It looks like this:
[remote "origin"]
fetch = +refs/heads/*:refs/remotes/origin/*
url = git@github.com:joyent/node.git
Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
