How to setup a practically free CDN using Backblaze B2 and Cloudflare

⚠️ Note 2023-01-21
Some things have changed since I originally wrote this in 2016. I have updated a few minor details, and the advice is still broadly the same, but there are some new Cloudflare features you can (and should) take advantage of. In particular, pay attention to Trevor Stevens' comment here from 22 January 2022, and Matt Stenson's useful caching advice. In addition, Backblaze, with whom Cloudflare are a Bandwidth Alliance partner, have published their own guide detailing how to use Cloudflare's Web Workers to cache content from B2 private buckets. That is worth reading,

Disable auto start for Android File Transfer
  • Close Android File Transfer
  • Open Activity Monitor and kill “Android File Transfer Agent”
  • Go to where you installed “Android File Transfer.app” (I have it under /Applications)
  • Ctrl+click –> “Show package contents”
  • Go to Contents/Resources
  • Rename “Android File Transfer Agent” to e.g. “Android File Transfer Agent_DISABLED”
  • Then go to “/Users/username/Library/Application Support/Google/Android File Transfer” and again rename the Agent app.

Pragmatic Touch Icons

NOTE I'm trying to find the most optimal fav/touch icon setup for my use-cases. Nothing new here. Read Mathias Bynens' articles on re-shortcut-icon and touch icons, a FAQ or a Cheat Sheet for all the details.

I'd like to hear how you approach this: @valuedstandards or comment on this gist.

The issue

You have to include a boatload of link elements pointing to many different images to provide (mobile) devices with a 'favicon' or 'touch icon':

Safer WordPress with these .htaccess additions
# Don't show errors which contain full path diclosure (FPD)
# Use that line only if PHP is installed as a module and not per CGI
