My Language Ranking Based on Coolness
With so many sites measuring programming language popularity, here’s the coolness, not popularity ranking of languages ranking by me. This is my PERSONAL opinion.
1. Ruby – need I say more? 😉
2. Objective-C
3. Go
4. C, not C++
5. Coffeescript – yes, I said it, ok?
6. Haskell
7. R
8. Swift

Setting Up a React Project
Simple Web Server with Ruby or Python
I was developing a Javascript app and wanted to run a web server pointing to current directory.
Using Ruby
A simple script to start a WEBrick server. You can modify the root directory to a subfolder if you’d like. I named this script “server” with chmod +x so I can run it with ./server
#!/usr/bin/env ruby
require 'webrick'
server = WEBrick::HTTPServer.new(Port: 8000, DocumentRoot: ".")
Signal.trap('INT') { server.shutdown }
server.start
Python
A simple command using python -m SimpleHTTPServer
