Protonet File API

Protonet supports the WebDAV protocol. You can access it under the following URL:

https://yourbox.protonet.info/dav

The API expects XML and responds with XML. WebDAV provides you with all features necessary to work with the Protonet file system (create, delete, list files/folders, ...). There are libraries/clients for almost every programming language that simplify working with the webdav server.

Why you should look into Angular.js

Web apps are getting more and more complicated these days. More and more logic moves from the backend to the frontend. Libraries and frameworks of the past weren't built with these new requirements in mind. For example using jQuery to manage a large and complex web app quickly ends up in a very difficult to maintain code base.

Fortunately, a new generation of frameworks are being built to meet these challenges and Angular.js is one of them! Let me introduce you to some of the major benefits of using Angular.

Declarative user interface and databindings

Angular uses HTML to define the user interface, which is much more intuitive than defining the interface procedurally in Javascript.

Following a quick example. Give it a try using an interactive JSFiddle!

(function() {
  // Reset OTTO Nav HTML for to remove existing event listeners
  var $container = $(".homepage");
  var html = $container.html();
  $container.html(html);

  // Get nav items
  var $items = $container.find(".sort");

  $items.each(function(i) {

var fs            = require("fs"),
    exec          = require("child_process").exec,
    macAddresses  = {
      "00:25:00:48:26:b3": {
        name:   "Christopher",
        times:  0,
        log:    0
      },
      "74:e5:0b:a6:6f:94": {
        name:   "Wolfgang",

function traverseFileTree(item, path) {
  path = path || "";
  if (item.isFile) {
    // Get file
    item.file(function(file) {
      console.log("File:", path + file.name);
    });
  } else if (item.isDirectory) {
    // Get folder contents
    var dirReader = item.createReader();

// Minify and compile your javascript via node.js on the command line
//
// Usage:
// node minify.js "my_script.js"

var script      = process.argv[2],
    http        = require("http"),
    queryString = require("querystring"),
    fs          = require("fs");
