the macOS Gatekeeper check! It was disabled on 2026-09-01.

Making use of the observation that Pi is the area of a circle with diameter equal to one, a brute force calculation of Pi would be to:

randomly generate points in a square
count the points within the circle and the total number of points
multiple the ratio of points in the circle to total number of points by the area of a square with a side the length of the diameter of the circle (in this case two (2))

Troubleshooting "no sound" issue.

NYT Spelling Bee solver written in Ruby. It should work fine on any BSD/Linux/Unix system with Ruby installed.

In a terminal:

git clone git@gist.github.com:3488d03f298cef55289bc899e79e18a3.git spelling_bee
cd spelling_bee
irb -r ./spelling_bee.rb

This has only been tested with Ruby 3.1.2. YMMV.

In this demo we will:

Learn why testing is important
Learn about testing "philosophies"
Learn how RSpec makes testing "productive and fun" including:
- Units specs (Models: "M")
- Request & Routing specs (Controllers: "C")
- View specs (Views: "V")
System specs (Models, Views & Controllers: "MVC")
