How to take full-page screenshots with Selenium and Google Chrome in Ruby
#!/usr/bin/env ruby
require 'selenium-webdriver'
wd = Selenium::WebDriver.for :remote, url: 'http://10.3.1.7:4444/wd/hub', desired_capabilities: :chrome
wd.navigate.to 'https://snipt.net/restrada/python-selenium-workaround-for-full-page-screenshot-using-chromedriver-2x/'
# Get the actual page dimensions using javascript

width = wd.execute_script("return Math.max(document.body.scrollWidth, document.body.offsetWidth, document.documentElement.clientWidth, document.documentElement.scrollWidth, document.documentElement.offsetWidth);")

Template composition with inclusion

Every template language I have seen provides some mechanism for one template to include another, thus supporting the reuse of repeated elements like headers and footers. The included templates are called partials in Mustache parlance:

<!-- home.hbs -->
<html>
<body>
  {{> header}}
  <p> HOME </p>
  {{> footer}}

JavaScript code for generating Firebase Push IDs
/**
* Fancy ID generator that creates 20-character string identifiers with the following properties:
*
* 1. They're based on timestamp so that they sort *after* any existing ids.
* 2. They contain 72-bits of random data after the timestamp so that IDs won't collide with other clients' IDs.
* 3. They sort *lexicographically* (so the timestamp is converted to characters that will sort properly).
* 4. They're monotonically increasing. Even if you generate more than one in the same timestamp, the
* latter ones will sort after the former ones. We do this by using the previous random bits
* but "incrementing" them by 1 (only in the case of a timestamp collision).

Hello, visitors! If you want an updated version of this styleguide in repo form with tons of real-life examples… check out Trellisheets! https://github.com/trello/trellisheets


Trello CSS Guide

“I perfectly understand our CSS. I never have any issues with cascading rules. I never have to use !important or inline styles. Even though somebody else wrote this bit of CSS, I know exactly how it works and how to extend it. Fixes are easy! I have a hard time breaking our CSS. I know exactly where to put new CSS. We use all of our CSS and it’s pretty small overall. When I delete a template, I know the exact corresponding CSS file and I can delete it all at once. Nothing gets left behind.”

You often hear updog saying stuff like this. Who’s updog? Not much, who is up with you?

Setup for an easy to use, simple reverse http tunnels with nginx and ssh. It's that simple there's no authentication at all. The end result, a single ssh command invocation gives you a public url for your web app hosted on your laptop.

What

A lot of times you are developing a web application on your own laptop or home computer and would like to demo it to the public. Most of those times you are behind a router/firewall and you don't have a public IP address. Instead of configuring routers (often not possible), this solution gives you a public URL that's reverse tunnelled via ssh to your laptop.

Because of the relaxation of the sshd setup, it's best used on a dedicated virtual machine just for this (an Amazon micro instance for example).
