XAC - Xen API Console

• A browser based, client side only, single page, application that allows you to control anything that has XenAPI running (e.g. XenServer).
• Based on the previous works of John Ludlam
• Using the previous work to construct the first component

XenAPI-jQuery

• A Xen API XMLRPC jQuery Client Library
• Please select your API call out of 1400+ possibilities
• Written in Coffeescript

Coffeescript - Introduction

• CoffeeScript is an attempt to expose the good parts of JavaScript in a simple way.
• CoffeeScript "compiles" into javascript
• CoffeeScript is not a superset of JavaScript
• Inspired by the Ruby and Python language

Coffeescript - Example

Coffeescript

eat food for food in foods when food isnt 'chocolate'

Javascript

for (_k = 0, _len2 = foods.length; _k < _len2; _k++) {
	food = foods[_k];
	if (food !== 'chocolate') {
		eat(food);
	}
}

XenAPI-jQuery - Usage

var client = new XenAPI(username,password,hostUrl);

client.init(function(error, result) {
    if(error) {
        console.log(error);
    } else {
    	// Run any api call you want
        client.VM.get_all(function(error,result) {
            var all_vm = result;
        })
    }
 })

XAC - SASS

Sass is an extension of CSS3. Adding nested rules, variables, mixins, selector inheritance, and more

SCSS

$blue: #3bbfce;
$margin: 16px;

.content-navigation {
  border-color: $blue;
  color:
    darken($blue, 9%);
}

.border {
  padding: $margin / 2;
  margin: $margin / 2;
  border-color: $blue;
}

XAC - Ember.js

Ember.js does a lot of "magic"...

App.IndexRoute = Ember.Route.extend({
  model: function() {
    var people = [
      App.Person.create({
        firstName: "Tom",
        lastName: "Dale"
      }),
      App.Person.create({
        firstName: "Yehuda",
        lastName: "Katz"
      })
    ];
    return people;
  }
});

Ember.js does a lot of "magic"...

<script type="text/x-handlebars" id="index">
 <h1>People</h1>
  <ul>
   {{#each model}}
    <li>Hello, <b>{{fullName}}</b>!</li>
   {{/each}}
  </ul>
</script>

Thesis

• Information Engineering
• Bridge between Business and Engineering
• Applying this approach on the open sourcing

Transition from proprietary to open source - a case study at Citrix

• Case Study
• Descriptive research
• Gathering data

Thesis - Goal

The objective is to provide a framework or model that will allow insights into the transition process from proprietary to open source.

How would a model for the transition from proprietary to open source be defined based on the Citrix XenServer case study?

Thesis - Steps

• What are the aspects of existing open source projects
• Get all the information on XenServer as possible
• Try to find match and mismatch between both data sources

Thesis - High Level Model

Thesis - Business Model

• User Organizations
• Open Source Support Organizations
• Professional Open Source Organizations

Thesis - Process

• Software development Practices
• Tooling and/or Infrastructure
• Communication

Thesis - Product

• Licensing
• Testing
• Releasing
• Maintenance
• Architecture

Thesis - Social

• Community and Teams
• Membership
• Cooperation, Coordination and Control
• Governance
• Trust and Social Accountability

Thesis - Some things I learned

• Open Sourcing is mostly about people
• Open source does not mean the same to everyone
• License is the key to everything
• Writing a thesis is harder than it looks
