Falsehoods programmers believe about addresses

This is an anchor-linked version of the excellent, amazing original opus magnum by Michael Tandy.

An address will start with, or at least include, a building number.

Counterexample: 1A Egmont Road, Middlesbrough, TS4 2HT

Instructions

CloudFlare is an awesome reverse cache proxy and CDN that provides DNS, free HTTPS (TLS) support, best-in-class performance settings (gzip, SDCH, HTTP/2, sane Cache-Control and E-Tag headers, etc.), minification, etc.

Make sure you have registered a domain name.
Sign up for CloudFlare and create an account for your domain.
In your domain registrar's admin panel, point the nameservers to CloudFlare's (refer to this awesome list of links for instructions for various registrars).
From the CloudFlare settings for that domain, enable HTTPS/SSL and set up a Page Rule to force HTTPS redirects. (If you want to get fancy, you can also enable automatic minification for text-based assets [HTML/CSS/JS/SVG/etc.], which is a pretty cool feature if you don't want already have a build step for minification.)

Why

Doing require extensions correctly is essential, because:

Users should be able to install multiple extensions in succession, and have them work together.
Coverage tools like nyc need it to reliably supply coverage information that takes into account sourcemaps from upstream transforms.
Because non-standard, un-predictable behavior causes hard to solve bugs, and major headaches for project maintainers.

What is a require extension anyways?
