This is the "Iris" dataset. Originally published at UCI Machine Learning Repository: Iris Data Set, this small dataset from 1936 is often used for testing out machine learning algorithms and visualizations (for example, Scatter Plot). Each row of the table represents an iris flower, including its species and dimensions of its botanical parts, sepal and petal, in centimeters.

The HTML page provides the basic code required to load the data and display it on the page (as JSON) using D3.js.

Intro

Bellow follows a list of aliases, split between beginner and advanced.

To start using them right away you should place the aliases you like most in a file like ~/.zsh/git. Now all that remains is to add the following line to your ~/.zshrc or ~/.bashrc:

. ~/.zsh/git # git aliases

1. Install tmux + tmuxinator

gem install tmuxinator

2. Add ~/.tmuxinator project specific configurations

# File: ~/.tmuxinator/project-name.yml

name: project-name

	const todo = (state, action) => {
	switch (action.type) {
	case 'ADD_TODO':
	return {
	id: action.id,
	text: action.text,
	completed: false
	};
	case 'TOGGLE_TODO':
	if (state.id !== action.id) {

	# when creating stack with zero capacity any push should overflow
	# when one is pushed one is on top
