What forces layout/reflow. The comprehensive list.

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

Список литературы для ознакомления с concurrent programming и реализацией этих принципов и подходов на ruby. Огромное спасибо @brainopia за составление.

Введение

Начать стоит отсюда. Не пугайтесь то, что это книга по незнакомой OS, эти термины практически везде одинаковые и здесь они изложены в понятной для начинающих форме.

http://www.qnx.com/developers/docs/6.4.1/neutrino/getting_started/s1_procs.html

Прочесть нужно треть главы до подраздела "Starting a process", если С не пугает, читайте полностью. После прочтения вы будете понимать, что такое process, thread, mutex, priorites, semaphores, scheduler, contex-switch, kernel states.

A script for cleaning up Git repositories; it deletes branches that are fully merged into `origin/master`, prunes obsolete remote tracking branches, and as an added bonus will replicate these changes on the remote.
#!/bin/bash

# Adapted from the original by Yorick Sijsling
git checkout master &> /dev/null
# Make sure we're working with the most up-to-date version of master.

The way I had to add a github repo webhook for pull requests

This is more complex than necessary.

GitHub webhooks for a URL by default only fire on repo pushes. There appears to be no way in the web UI to set up webhooks for other events. And so we go to the API. I prefer to do this type of thing with Hurl.

function resolveURL(baseURL, relativeURL) {
var html = document.implementation.createHTMLDocument("");
var base = html.createElement("base");
base.setAttribute("href", baseURL);
var a = html.createElement("a");
a.setAttribute("href", relativeURL);
html.head.appendChild(base);
html.body.appendChild(a);
return a.href;
