Pushing to Multiple Git Repos

If a project has to have multiple git repos (e.g. Bitbucket and Github) then it's better that they remain in sync.

Usually this would involve pushing each branch to each repo in turn, but actually Git allows pushing to multiple repos in one go.

If in doubt about what git is doing when you run these commands, just

Some links from twitter on the topic of parsing PSD files (haven't looked into them in details). PSD include a flattened rasterized image so this is easy to load if that's the only thing you need. Most software / librairies have support for extracting this flattened data (e.g. stb_image.h does).

However if you want access to individual layers, render non-rasterized layers, emulate every photoshop features, extract or apply effects with more granularity, more code is needed. May range from easy to lots-of-work depending on what exactly you need.

As far as I know there isn't a trivial stb-like ready-to-use C++ library to do that sort of things. Posting all links here. Some are probably bloated or hard to use into your project, some lacking features.

TODO: Actually look into the pros/cons of all those.

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

bendc

var elements = document.querySelectorAll("div"),
    callback = (el) => { console.log(el); };

// Spread operator
[...elements].forEach(callback);

// Array.from()
Array.from(elements).forEach(callback);

// for...of statement

// From Buffer to ArrayBuffer:

function toArrayBuffer(buffer) {
    var ab = new ArrayBuffer(buffer.length);
    var view = new Uint8Array(ab);
    for (var i = 0; i < buffer.length; ++i) {
        view[i] = buffer[i];

#Linux - Running a Node Service (PM2) PM2 is a replacement for Forever which is used to run Node services (see http://devo.ps/blog/2013/06/26/goodbye-node-forever-hello-pm2.html). It has a number of advantages over forever:

• Log aggregation
• API
• Terminal monitoring
• Clustering
• JSON configuration

Installation

bag-man

var os = require("os");

//Create function to get CPU information
function cpuAverage() {

  //Initialise sum of idle and time of cores and fetch CPU info
  var totalIdle = 0, totalTick = 0;
  var cpus = os.cpus();

  //Loop through CPU cores
