Make sure the domain you picked points at the IP of your Redash server.
Switch to the root user (sudo su).
Create a folder named nginx in /opt/redash.
Create in the nginx folder two additional folders: certs and certs-data.
Create the file /opt/redash/nginx/nginx.conf and place the following in it: (replace example.redashapp.com with your domain name)
```
upstream redash {
    server redash:5000;
}
```

The list of actions listed below was taken mostly from Book Of Zeus with minor modifications and did the job well for Ubuntu version, which was available at that moment (May 2016). This gist was created for internal use and was never meant to be discovered by the web, although Google managed to find and index this page, which was a great surprise for me. Please check the original source for the updated information (links are provided in most of the sections), and read the comments below: they provide more details about the usage experience.

System Updates

Keeping the system updated is vital before starting anything on your system. This will prevent people to use known vulnerabilities to enter in your system.

Destructuring(or pattern matching) is a way used to extract data from a data structure(tuple, list, record) that mirros the construction. Compare to other languages, Elm support much less destructuring but let's see what it got !

Tuple

myTuple = ("A", "B", "C")
myNestedTuple = ("A", "B", "C", ("X", "Y", "Z"))

Architecture in Elm

This document is a collection of concepts and strategies to make large Elm projects modular and extensible.

We will start by thinking about the structure of signals in our program. Broadly speaking, your application state should live in one big foldp. You will probably merge a bunch of input signals into a single stream of updates. This sounds a bit crazy at first, but it is in the same ballpark as Om or Facebook's Flux. There are a couple major benefits to having a centralized home for your application state:

There is a single source of truth. Traditional approaches force you to write a decent amount of custom and error prone code to synchronize state between many different stateful components. (The state of this widget needs to be synced with the application state, which needs to be synced with some other widget, etc.) By placing all of your state in one location, you eliminate an entire class of bugs in which two components get into inconsistent states. We also think yo

Resize a Hard Disk for a Virtual Machine

Our Virtual Machines are provisioned using Vagrant from a Linux base box to run using VirutalBox. If the Hard Disk space runs out and you cannot remove files to free-up space, you can resize the Hard Disk using some VirtualBox and Linux commands.

Some assumptions

The following steps assume you've got a set-up like mine, where:

	# Edit your fish prompt with `funced fish_prompt` and
	# add the following to a desired place in the function.
	# Save the prompt after editing with `funcsave fish_prompt`.

	# Set a variable for workspace color.
	set -l tfworkspace_color (set_color green)

	# Append the workspace name at the current prompt position if
	# the directory contains a .terraform subdirectory
	if test -d .terraform

	For a safe and fast Erlang SSL server, there's a few
	configuration values you might want by default:

	[{ciphers, CipherList}, % see below
	{honor_cipher_order, true}, % pick the server-defined order of ciphers
	{secure_renegotiate, true}, % prevent renegotiation hijacks
	{client_renegotiation, false}, % prevent clients DoSing w/ renegs
	{versions, ['tlsv1.2', 'tlsv1.1']}, % add tlsv1 if you must
