(C-x means ctrl+x, M-x means alt+x)

How to: Allow Node to bind to port 80 without sudo

TL;DR

Only do this if you understand the consequences: all node programs will be able to bind on ports < 1024

sudo setcap 'cap_net_bind_service=+ep' /usr/local/bin/node

Make /robots.txt aware of the Rails environment

You probably don't want Google crawling your development staging app. Here's how to fix that.

$ mv public/robots.txt config/robots.production.txt
$ cp config/robots.production.txt config/robots.development.txt

Now edit config/routes.rb to add a route for /robots.txt, and add the controller code.

function trackJavaScriptError(e) {
    var ie = window.event || {};
    var message = e.message || ie.errorMessage || '<no message>'
    var filename = e.filename || ie.errorUrl || '<no filename>';
    var lineno = e.lineno || ie.errorLine || '<no lineno>';
    var colno = e.colno || ie.errorColumn || '<no colno>';
    var source = filename + ':' + lineno + ':' + colno;
    ga('send', 'event', 'JavaScript Exception', message, source, {'nonInteraction': 1});
}

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

var Article = require('../../../models/article');

Those suck for maintenance and they're ugly.
