Displaying HDMI sources on Apple Vision Pro

While it's possible to stream most content to Apple Vision Pro directly over the internet, having the ability to use Apple Vision Pro as an HDMI display can still be useful.

Since Apple Vision Pro does not support connecting to an HDMI input directly or using an HDMI capture card, we have to be a little creative to make this work. NDI provides the ability to stream HDMI content over a local network with really low latency, and it works great with Apple Vision Pro.

This page shows the setup I’m using.

JWT Auth + Refresh Tokens in Rails

This is just some code I recently used in my development application in order to add token-based authentication for my api-only rails app. The api-client was to be consumed by a mobile application, so I needed an authentication solution that would keep the user logged in indefinetly and the only way to do this was either using refresh tokens or sliding sessions.

I also needed a way to both blacklist and whitelist tokens based on a unique identifier (jti)

Before trying it out DIY, I considered using:

# Allow Rails to use assets from Node packages
package_json = Rails.root.join("package.json")
Rails.configuration.watchable_files << package_json
Rails.configuration.to_prepare do
  node_config = JSON.parse(package_json.read)
  paths = Rails.configuration.assets.paths
  node_modules = Rails.root.join("node_modules")
  paths.reject! { |p| p.to_s.start_with?(node_modules.to_s) }
  node_config["dependencies"].keys.each do |node_module|
    module_dir = node_modules.join(node_module)
