Implementation of a horizontal slider component with Stimulus and Tailwind CSS
View slider.html
This code is meant to accompany the guide originally published at
It intentionally pulls in Tailwind CSS and Stimulus without a build system to simplify the guide. You shouldn't do this with a real application,
you should use a build system like webpack!

Last active Aug 29, 2015
Method for finding pythagorean triples in a given range. Returns the triple with the largest sum that is less than the given perimeter
View triples.rb
def find_biggest_triple(perimeter)
all_triples = [] # Empty array to hold all of the triplets
max_side_length = perimeter/2 # This isn't necessary because we filter but the method runs a lot faster if we cut down how many times the all_triples loops need to run. a + b should always be greater than c so no need to build triples that won't be selected
# Run outer loop perimeter/2 times - This is our hypotenuse
max_side_length.times do |a|
a.times do |b|
b.times do |c|
# Pythagorean triplet is found if the square of the two shorter sides (the two interior loops) equals the square of the hypotenuse
if c**2 + b**2 == a**2
