# PostgreSQL’s question mark (`?`) jsonb operator can pose an issue when using 
# Active Record, since `?` is used to denote bind variable substitution. One
# way to work around this is to use named bind variable substitution with a
# hash instead.

OAuth Redirect Server for Local Development

Some OAuth providers (like Google), limit what hosts can be used for redirect URIs. This can be problematic when using a hostname-based local development server (like Pow or Invoker). This very simple redirection server can be used to work around this restriction.

Instagram 2FA QR Code Generator

Instagram doesn’t make it easy to enable 2FA unless you’re using Google Authenticator or Duo Security. If you want to use it with another authenticator app—like 1Password—this script will generate the QR code you need to easily set that up.

Usage

The Ruby script makes use of Bundler’s inline functionality and will automatically install the depenedncies as system gems.
