Ansible

Understanding Ansible

Ansible is a powerful, simple, and easy to use tool for managing computers. It is most often used to update programs and configuration on dozens of servers at once, but the abstractions are the same whether you're managing one computer or a hundred. Ansible can even do "fun" things like change the desktop photo or backup personal files to the cloud. It can take a while to learn how to use Ansible because it has an extensive terminology, but once you understand the why and the how of Ansible, its power is readily apparent.

Ansible's power comes from its simplicity. Under the hood, Ansible is just a domain specific language (DSL) for a task runner for a secure shell (ssh). You write ansible yaml (.yml) files which describe the tasks which must run to turn plain old / virtualized / cloud computers into production ready server-beasts. These tasks, in turn, have easy to understand names like "copy", "file", "command", "ping", or "lineinfile". Each of these turns into shell comma

I got hit by the weird group reassignment when I upgraded to Mavericks. In my case the group was macports (!). I’ve seen one report from a user who got cloakproxy after the 10.11 upgrade, so apparently the bug is still there.

For some reason the OS X upgrader sometimes picks a group and changes the PrimaryGroupID to 20. Here’s the confirm:

dscl . -read Groups/cloakproxy
dscl . -read Groups/staff

And the fix:

function mapValues(obj, fn) {
  return Object.keys(obj).reduce((result, key) => {
    result[key] = fn(obj[key], key);
    return result;
  }, {});
}

function pick(obj, fn) {
  return Object.keys(obj).reduce((result, key) => {
    if (fn(obj[key])) {

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

var copy = Object.create(Object.getPrototypeOf(node));
Object.getOwnPropertyNames(node).forEach(propName => {
