I've had to install and configure these things a few times, and I always forget how to do it, so here it is for posterity:

Update brew and install pandoc:
```
brew update
brew install pandoc
```
Install mactex from https://www.tug.org/mactex/

Air Quality in Madrid

This is a project for https://cartodb.github.io/hackarto.vl (2018, June 6th). The objective is to create a VIZ with CARTO.VL library to show AIR QUALITY in Madrid, using Madrid's OpenData

HOW IT WAS CREATED

These were the main steps:

Get air quality stations dataset from Madrid's OpenData

#Setting Up TinCan API with Moodle LMS and Learning Locker LRS

#Part 1: Virtual Container

Before we get our hands dirty with the entire setup, it is necessary to ensure we do not mess with the existing installation. Setting up and configuring a local server is tricky and may sometimes break your existing configuration rendering other programs which rely on it useless. So we will use LXC to create a virtual container, where we will do all good stuff. You can read the official LXC documentation here or a brief introduction about LXC here or get started right away with the commands below.

sudo apt-get install lxc lxd-client
sudo lxc-create -t download -n LMSprototype

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

Clarify and agree on the scope of the system

User cases (description of sequences of events that, taken together, lead to a system doing something useful)
- Who is going to use it?
- How are they going to use it?

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

Making Accessible Ember Components

Making the web accessible is important. We have ethical and, in some cases, legal obligations to ensuring access to all of users.

Luckily for us, it's easy to make an accessible Ember Component.

What are components?

To understand the accessibility story around Ember Components, we have to start by talking about Web Components. Ember Components are designed to be interoperable with the final Web Components API.
