Export Plex library titles via Node

I wanted to export all titles from the Plex library on my Mac and couldn't find a good tool.

This is a tiny, quick-and-dirty Node JS script, using node-plex-api.

It assumes you have node and npm installed.

Then just download this "script.js" and run:

npm install plex-api --save
node script.js your_plex_username your_plex_password > plex.txt

Run a block on a list of things in a limited number of concurrent threads. Mostly for the fun of it – there are more featureful libs like
View each_in_thread_pool.rb
# 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.
class EachInThreadPool
def, pool_size:, &block)
queue =
inputs.each { queue << _1 } {

Ruby code to check if a pathname is contained within another pathname (e.g. "/foo/bar/baz" within "/foo/bar") without being tricked by "..". Written with @olleolleolle.

def self.in_dir?(path, dir:)

Created Nov 21, 2020
AppleScript proof-of-concept for toggling Zoom mute. Gracefully handles Zoom not being installed, or not running, or not currently being in a meeting.
View toggle_zoom_mute.scpt
-- Based on:
tell application "System Events"
if exists window 1 of process "" then
tell application process ""
if exists (menu 1 of menu bar item "Meeting" of menu bar 1) then
set meetingMenu to menu 1 of menu bar item "Meeting" of menu bar 1
set canMute to exists menu item "Mute audio" of meetingMenu
set canUnmute to exists menu item "Unmute audio" of meetingMenu

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.

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 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.

Phoenix LiveView hook that makes links with a "phx-click" still trigger the default navigation event, and also prevents clicks on buttons inside these links from doing the same.
View app.js
// 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.
Hooks.AllowLinkDefaultAndPreventNestedDefault = {
mounted() {
this.el.addEventListener("click", (e) => {
// `closest` in case we click an element inside a button, e.g. an icon.
