How to automatically start ssh server on boot on Windows Subsystem for Linux

Microsoft partnered with Canonical to create Bash on Ubuntu on Windows, running through a technology called the Windows Subsystem for Linux. Below are instructions on how to set up the ssh server to run automatically at boot.

Edit the /etc/ssh/sshd_config file by running the command sudo vi /etc/ssh/sshd_config and do the following
1. Change Port to 2222 (or any other port above 1000)
2. Change PasswordAuthentication to yes. This can be changed back to no if ssh keys are setup.
Restart the ssh server:
- sudo service ssh --full-restart
With this setup, the ssh server must be turned on every time you run Bash on Ubuntu on Windows, as by default it is off. Use this command to turn it on:

Git-workflow vs feature branching

When working with Git, there are two prevailing workflows are Git workflow and feature branches. IMHO, being more of a subscriber to continuous integration, I feel that the feature branch workflow is better suited, and the focus of this article.

If you are new to Git and Git-workflows, I suggest reading the atlassian.com Git Workflow article in addition to this as there is more detail there than presented here.

I admit, using Bash in the command line with the standard configuration leaves a bit to be desired when it comes to awareness of state. A tool that I suggest using follows these instructions on setting up GIT Bash autocompletion. This tool will assist you to better visualize the state of a branc

set -e, -u, -o, -x pipefail

The set lines

These lines deliberately cause your script to fail. Wait, what? Believe me, this is a good thing.
With these settings, certain common errors will cause the script to immediately fail, explicitly and loudly. Otherwise, you can get hidden bugs that are discovered only when they blow up in production.

set -euxo pipefail is short for:

set -e
set -u

Frontend interview questions

First, you should ask for his/her Github username and check public repositories.

Note: Keep in mind that many of these questions are open-ended and could lead to interesting discussions that tell you more about the person's capabilities than a straight answer would.

General

What Javascript Frameworks do you know? Which one do you like? Why?
What is the atomic design?

Coined by Brad Frost, Atomic Design is a methodology that involves breaking a website layout down into its basic components, which are then reused throughout the site. You have Atoms => Molecules => Organisms => Templates => Pages.

Can you name two programming paradigms important for JavaScript app developers?
