Chromium OS ft. Docker

Chromium OS is cool. Chromium OS with crouton is cooler. Chromium OS with Docker is even cooler. This is specifically a guide for the Chromebook Pixel 2 (2015), but I can't think of any reason it wouldn't work with other devices.

Create a build environment
Customize the kernel
Build Chromium OS
Flash Chromium OS to USB
Install Chromium OS

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

You can trigger a GitHub Pages (Jekyll) rebuild with a single API call. This is pretty useful for auto-publishing blog posts from a bot like Zapier in conjunction with future: false in your Jekyll config.yml. Just future-date your posts, and they'll go live when that date rolls around. I use a version of this setup for my blog at greghaskins.com.

Setup

Create a GitHub personal access token and save it somewhere. It needs to have the repo access scope (at least).
Create a file at the root of your repo (e.g. .publish) with some dummy content.
```
$ echo ".publish" > .publish
```
