Last active December 8, 2020 19:48
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:)
path_parts = path.expand_path.each_filename.to_a
dir_parts = dir.expand_path.each_filename.to_a
return false if path_parts == dir_paths
dir_parts.zip(path_parts).all? { |x, y| x == y }

Created November 21, 2020 23:24
AppleScript proof-of-concept for toggling Zoom mute. Gracefully handles Zoom not being installed, or not running, or not currently being in a meeting.
-- Based on: https://devforum.zoom.us/t/easiest-way-to-get-mute-status/18462/7
tell application "System Events"
if exists window 1 of process "zoom.us" then
tell application process "zoom.us"
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 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.

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.
// 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.
if (e.target.closest("button")) {
e.preventDefault()
} else {

Last active April 20, 2020 06:42
Ruby script (gemdiffs.rb) to generate Coditsu gem diffing URLs from a Gemfile.lock diff, to help catch hijacked gems, or just to keep on top of changes. Also supports gems sourced straight from GitHub. There's also updategems.rb which updates gems and calls gemdiffs.rb to pre-fill the commit message.
#!/usr/bin/env ruby
# Usage example (in a Terminal):
#
# bundle update
# script/gemdiffs.rb
# Rubygems version diffs.
puts `git diff Gemfile.lock`.lines.
select { |line| line.match?(/^[+-] \w/) }.
