I need assistance with preparation for coding session
The CodeSignal screen is meant to test general coding ability.
I’ll be asked to implement a simple coding project from a spec and develop it to the point that it passes some tests.
I should prioritize
a) writing code that passes as many tests as possible and
b) progressing through all four levels quickly.
It'll essentially be a toy simulation of an app that won't require anything except the standard library of chosen programming language.
Note there's no framework/UI or anything similar — basically, it's like the core business logic of an app, but nothing else.
It won’t test detailed knowledge of algorithms, compute systems, or machine learning.

Node app deploy with nginx & SSL

Node.js Deployment

Steps to deploy a Node.js app to DigitalOcean using PM2, NGINX as a reverse proxy and an SSL from LetsEncrypt

1. Sign up for Digital Ocean

If you use the referal link below, you get $10 free (1 or 2 months) https://m.do.co/c/5424d440c63a

2. Create a droplet and log in via ssh

I will be using the root user, but would suggest creating a new user

move pritunl between servers

Migrating your pritunl install between servers

This is a small write up about how to migrate your pritunl install between servers. It's not especially detailed because I'm lazy and your migration story will most likely be different. All this can be avoided by using a remote/hosted mongo instance(compose.io, mongolab, etc.) and simply pointing your pritunl instance at that. If you want more details ask, and I'll do my best to answer and update this write-up accordingly. Also, feel free to criticize my grammar and spelling.
