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,

Architecture

• Use Onion architecture

  • Dependencies go inwards. That is, the Core domain doesn't know about outside layers

• Use pipeline model to implement workflows/use-cases/stories

  • Business logic makes decisions
  • IO does storage with minimal logic
  • Keep Business logic and IO separate

• Keep IO at edges

58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;

What I Wish I'd Known About Equity Before Joining A Unicorn

Disclaimer: This piece is written anonymously. The names of a few particular companies are mentioned, but as common examples only.

This is a short write-up on things that I wish I'd known and considered before joining a private company (aka startup, aka unicorn in some cases). I'm not trying to make the case that you should never join a private company, but the power imbalance between founder and employee is extreme, and that potential candidates would

Working with SQL syntax trees in F#

Update 12/15/2016 - Added Sql generation

Welcome to my blog post for #FsAdvent 2016.

If you're using a relational database, as your application grows in size, at some point you may find yourself looking for an SQL parser. This can give you lots of leverage, for example allowing you to:

• Do permission checks on queries before executing them
• Rewrite incorrect or inefficient queries

Introduction

Here is a collection of tips and tricks I've picked up about doing performance analysis on Node. Included is a build script that should get a base install of Ubuntu fully functional and ready for all the things we'll be going through.

The script pulls a lot of code from the latest master of each repository. So it's possible that something may fail, but to date I haven't had any issues.

First, go ahead and run the script. Then go take a nice long break. It'll
