    ##JavaScript
 tools 


Install jshint and Node.js

wget https://raw.github.com/coolaj86/dotfiles/master/.jshintrc
then install node.js from http://nodejs.org/  or
https://github.com/joyent/node/wiki/Installing-Node.js-via-package-manager
finally do this:
npm install -g jshint
'pushd ~'

curl https://raw.github.com/coolaj86/dotfiles/master/.jshintrc > ~/.jshintrc
wget https://raw.github.com/coolaj86/dotfiles/master/.jshintrc

opening a file:
on linux:  xdg-open index.html

on mac:    open index.html


inside the main JS function, add "use strict"; to tell jshint to use Version 5 of JavaScript


make sure you have wget curl for linux: sudo apt-get install wget curl for mac: sudo chown -R whoami /usr/local/ brew install wget curl


install zshell: https://github.com/robbyrussell/oh-my-zsh for linux: sudo apt-get install zsh type "which zsh" it should say: /usr/bin/zsh type "chsh -s /usr/bin/zsh" it will prompt for your password then after that, close the terminal, and log out of ubuntu and then log back in and you should be good.

##Ruby
 gems & tools 

1. `j@ubuntu~$ gem install pry`  => This goes to rubygems.org online to download the "pry" gem

gem install rspec in terminal to install rspec--

to run Rspec in terminal : rspec --color file_name_spec.rb

Sinatra: gem install sinatra sinatra-contrib to install and gem list sinatra to confirm it has been installed.

ruby file_name.rb -o 0.0.0.0   for Sinatra host
 commands & tricks

1.  `#!/usr/bin/env ruby`  
then add `chmod a+x file_name.rb` in command line so you can run your program by calling `./file_name.rb` without typing ruby in front

require ("./contact") the ./ part asks to look for the file contact in the current folder that you are in, or the folder where your current file where this line is written is saved. Ruby automatically knows it is looking for a .rb file, so you don't need to write the file extension. This is how you reference other files in your ruby file.

##Sublime Text
 tools 


Sublime Linter: We've installed Sublime Linter through sublime package Control, this will give us error check while we type:

Getting files from Terminal:

j@ubuntu:~$ mkdir Code/wk1d3
j@ubuntu:~$ pushd Code/wk1d3/
j@ubuntu:~/Code/wk1d3$ wget https://gist.github.com/coolaj86/983abc67071fbb5d0143/
raw/0ae2430c4bcdb1574d7e392c0e0ab2c65dc08974/instructors.csv

wget retrieves the file from your url and saves it into your 
/Code/wk1d3 folder as "instructors.csv"

j@ubuntu:~/Code/wk1d3$ cat instructors.csv
running this will display the info in your csv file


in terminal: ping -c 1 www.google.com or ping -c www.yahoo.com will give you IP addresses.  When you type ifconfig you'll get a list of available interfaces.


find . in command line will return all the files in that folder
