Getting Started in Scala

This is my attempt to give Scala newcomers a quick-and-easy rundown to the prerequisite steps they need to a) try Scala, and b) get a standard project up and running on their machine. I'm not going to talk about the language at all; there are plenty of better resources a google search away. This is just focused on the prerequisite tooling and machine setup. I will not be assuming you have any background in JVM languages. So if you're coming from Python, Ruby, JavaScript, Haskell, or anywhere…  I hope to present the information you need without assuming anything.

Disclaimer It has been over a decade since I was new to Scala, and when I was new to Scala, I was coming from a Java and Ruby background. This has probably caused me to unknowingly make some assumptions. Please feel free to call me out in comments/tweets!

One assumption I'm knowingly making is that you're on a Unix-like platform. Sorry, Windows users.

JavaScript Log Wrapping

Wrapping console.log (et al.) in your own function to modify logging behavior.

Why?

You may want a simple way to:

jexchan

Multiple SSH Keys settings for different github account

create different public key

create different ssh key according the article Mac Set-Up Git

$ ssh-keygen -t rsa -C "your_email@youremail.com"

apoo

Create separate SSH key for your personal account and your company. Named them with different extensions in your .ssh folder. Upload them to your github account and finally create a config file for your SSH
Create a config file in ~/.ssh/

vim config:

# PERSONAL ACCOUNT Github
Host github.com-COOL
    HostName github.com
    User git
    IdentityFile ~/.ssh/id_rsa_COOL
