Note: as @clibois mentioned below, due to the DRM Netflix uses, all decoding has to be done in CPU, making it somewhat choppy.

Note 2: Even the RPi 3 suffers from these CPU limitations. There is the potentially risky option of overclocking your RPi 3, but I haven't tried this.

If you manage to get smooth playback, please contact me, or post your solution here

UPDATE: I can no longer get this method to work. I have tried using Chromium v47, and v48, and both result in Netflix error "Oops, something went wrong" / C7053-1807, for which I can find no description online. If you manage to get things up and running, please contact me!

Regular Event Loop

This shows the execution order given JavaScript's Call Stack, Event Loop, and any asynchronous APIs provided in the JS execution environment (in this example; Web APIs in a Browser environment)

Starving the Event Loop with microtasks

"What's the Event Loop?"

Sparked from this twitter conversation when talking about doing fast async rendering of declarative UIs in Preact

These examples show how it's possible to starve the main event loop with microtasks (because the microtask queue is emptied at the end of every item in the event loop queue). Note that these are contrived examples, but can be reflective of situations where Promises are incorrectly expected to yield to the event loop "because they're async".

• setTimeout-only.js is there to form a baseline

Learn by doing

If you're brand new to the language (welcome!) start here: http://jsforcats.com/ (Silly name, but excellent content)

If you've already got a little bit of coding under your belt, the ⁠⁠absolute best⁠⁠ place / way to learn is with https://nodeschool.io workshops (Full disclosure; I've written 2 of them)

They're all free open source at your own pace workshops where you are given a bit of info, a task, and you must code it up before you can move on (it runs unit tests over your code to verify you completed it)

Getting started

• Everything except images in a website is text, so it's a lot of reading and writing. As such, it makes sense to use an editor built for the purpose to make your life easier.
• Install Visual Studio Code (VSCode): https://code.visualstudio.com/
  • This is where you'll do all your code editing
  • Really, you only need the text editing portion of the editor, but for all the other features, check out this guide: https://code.visualstudio.com/docs/getstarted/userinterface
• There are 3 main technologies that make up a website: HTML, CSS, JavaScript (JS)

Read Shape Up by basecamp on a kindle / reMarkable / eReader

Basecamp's new book Shape Up is now available online (https://basecamp.com/shapeup) to read page-by-page.

There is a .pdf version, but that's not the best format for Kindle / other eReaders. Instead, we can convert the page-by-page into an eReader friendly format.

Part 1: Convert to a single page

NOTE: This has only been tested on Chrome
