On implementing a client for feature flags in your UI codebase

This document isn't an explainer on Feature Flags, you can find that with my amateur writeup, or literally hundreds of better writeups out there.

This document is also agnostic to the choice of service you'd use: LaunchDarkly or split.io or optimizely or whatever; that's orthogonal to this conversation.

Instead, this document is a list of considerations for implementing a client for using Feature Flags for User Interface development. Service providers usually give a simple fetch and use client and that's it; I contend that there's a lot more to care about. Let's dive in.

To encourage usage, we'd like for the developer experience to be as brutally simple as possible. So, this should be valid usage:

Setting up ssh public key authentication on macOS using a YubiKey 4

I largely followed Florin's blog post, but have a few notes to add regarding issues I encountered:

Basic setup notes

1. I used a YubiKey 4, while the blog describes using a YubiKey NEO. I'm sure a YubiKey 5 would also work. I'm also running macOS 10.13.6.
2. I installed GPGTools as recommended. However, as I'll note later, it seems that gpg-agent only automatically starts when gpg is used; for ssh, you'll need to ensure it's running.
3. Before generating your keys, decide what key size you want to use. If you run the list command inside gpg --edit-card, look for the Key attributes line to see what is currently selected. On my YubiKey 4, it defaulted to 2048 bits for all keys:

Key attributes ...: rsa2048 rsa2048 rsa2048
