UPDATE (2021-03-31): I've posted an improved version of this guide with newer versions of the software.

I hate when my images turn out like this:

Cloudflare fragment rendering/caching

This worker script will evaluate your origin response, and replace html comments marked as fragment:key with a respective prefetch defined in a X-Fragments response header.

Usage

Your origin must include the X-Fragments header, specifying the a comma separated list of prefetch requests to make for that response.

Recently, Let's Encrypt launched free wildcard certificates. While this is good news in and of itself, as it removes one of the last remaining reasons for expensive commercial certificates, I've unfortunately seen a lot of people dangerously misunderstand what wildcard certificates are for.

Therefore, in this brief post I'll explain why you probably shouldn't use a wildcard certificate, as it will put your security at risk.

A brief explainer

It's generally pretty poorly understood (and documented!) how TLS ("SSL") works, so let's go through a brief explanation of the parts that are important here.

The general (simplified) idea behind how real-world TLS deployments work, is that you:

# This task will notify Sentry via their API[1] that you have deployed
# a new release. It uses the release timestamp as the `version`
# (like 20151113182847) and the git ref as the optional `ref` value.
#
# This task requires several environment variables be set (or just 
# hardcode the values in here if you like living on the edge):
#
#   ENV['SENTRY_API_ENDPOINT'] : API endpoint, https://app.getsentry.com
#   ENV['SENTRY_ORG']          : the organization for this app
#   ENV['SENTRY_PROJECT']      : the project for this app

Make it real

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.

Ship it

Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

Do it with style
