Really simple example of using get_user_pages and memory aligned allocation using posix_memalign. Hope this helps!

Webkit Pseudo-Element Selectors (Shadow DOM Elements)

An ongoing project to catalogue all of these sneaky, hidden, bleeding edge selectors as I prepare my JSConf EU 2012 talk.

Everything is broken up by tag, but within each the selectors aren't particularly ordered.

I have not tested/verified all of these. Have I missed some or got it wrong? Let me know. - A

A friendly reminder that you may need to set this property on your target/selected element to get the styling results you want:

-webkit-appearance:none;

Getting the Alexa top 1 million sites directly from the server, unzipping it, parsing the csv and getting each line as an array.
var request = require('request');
var unzip = require('unzip');
var csv2 = require('csv2');
request.get('http://s3.amazonaws.com/alexa-static/top-1m.csv.zip')
.pipe(unzip.Parse())
.on('entry', function (entry) {
entry.pipe(csv2()).on('data', console.log);

Be aware that every rendering engine has its own implementation of prefixed properties. As extensions are made part of the standard, the unprefixed identifier is then substituted.

Prefixed style properties

-ms-accelerator

The -ms-accelerator property sets or retrieves a string that indicates whether the object represents a keyboard shortcut.

-ms-accelerator: false | true

Survey of screenshot-based CSS testing tools

Currently considering https://github.com/webdriverio/webdrivercss

Core Goals:

  • Can test in up-to-date versions of all major browsers
  • Can test on up-to-date versions of all major OSes
  • Can test in IE9 (because Bootstrap v4 will support IE9+)
  • Don't want to have to setup/maintain our own cluster of VMs running all the necessary OSes (and all the versions of Windows)
  • Workflow for management of reference/baseline/norm screenshots
