# Lets you call a block for each item in a list, just like `each`.
# But instead of running serially, it runs in a limited number of parallel threads.
# This is useful when you don't just want one thread per item, e.g. to avoid rate limiting or network saturation.

  def self.call(inputs, pool_size:, &block)
    queue = Queue.new
    inputs.each { queue << _1 }

As determined by https://github.com/breunigs/bravia-auth-and-remote/.

Specifically, I followed the setup instructions in its README and then ran

curl --silent -XPOST http://192.168.0.131/sony/system -d '{"method":"getRemoteControllerInfo","params":[],"id":10,"version":"1.0"}' | pbcopy

(with the IP of the TV on my network).

I then ran its output through an online JSON prettifier.

AWS Lambda Ruby script to get cat status from the SureFlap cat flap. Very rough-and-ready.

Intended to be used with an iOS shortcut to get cat status – see https://twitter.com/henrik/status/1321201656822943745 for a screenshot of the shortcut.

This is not a tutorial, just some public notes for my own future use.

Setup hints

Create this as a AWS Lambda running on Ruby.

// Fixes two issues:
// - Clicking a link with a `phx-click` attribute did not cause the link default (navigation) to trigger.
// - Clicking a button inside the link *would* cause the link default to trigger.
