6 pm : "Angular 2 Kickstart" by Geoff Filippi

Angular 2 is now in Release Candidate stage. We will use the new Angular CLI project to generate a new Angular 2 application. Next, we will take a quick tour through the scaffolded application structure. We will discuss how Angular 2 is bootstrapped and how modules are loaded. We will also show how to use the Angular CLI tool to generate a component and build our application. 

7 pm : Dinner and Networking

7:30 : "Angular 2 Observables" by Geoff Filippi

"Angular 2 Observables" by Geoff Filippi

Reactive Programming techniques are used to write the Angular 2 framework. The same APIs and techniques are exposed to Angular 2 developers for application development.

This talk will start with a brief overview of Reactive Programming. We will define and discuss the Observer Design Pattern. Observables are implemented in RxJS and are under consideration for standardization in ES2016. We will compare Observables, Promises, Events and callbacks. We will also discuss how Promises, Events and callbacks can be bridged into Observables.

Finally we will discuss how RxJS is used to implement Angular 2. We will explore how Observables are used in change detection and ngZone, Http, Async Facade and Forms. We will also discuss how to make use of RxJS and Observables in our Angular 2 applications.

6:30pm Announcements  
6:40pm Finding Graph Isomorphisms in GraphX and Graphframes, by Michael Malak
7:15pm NLP Walkabout, by Rob Oberbreckling  
8:00pm adjourn

This event is being held in cooperation with two other Meetup groups -- you only need to RSVP to one of them:

• Graph Nerds of Boulder

• Boulder/Denver Spark

Finding Graph Isomorphisms in GraphX and Graphframes - Abstract

This is a dry run of my upcoming presentation to Spark Summit https://spark-summit.org/2016/events/finding-graph-isomorphisms-in-graphx-and-graphframes/ It will not be live-streamed.

Identifying graph isomorphisms is one of the most powerful graph techniques, and has a wide variety of applications. In this presentation, you’ll see how to find simple graph isomorphisms in GraphX, and how the exciting new GraphFrames from AMPlab — intended for inclusion in Spark 2.x — allows the use of SQL and a subset of Cypher (the query language from Neo4j) to find more complex graph isomorphisms. Applications covered include finding missing data from Wikipedia (using the YAGO3 data set), which is a form of graph mining, and fraud detection. Also covered will be, due to its newness, a brief overview of GraphFrames, its performance over GraphX due to Catalyst and Tungsten, and how to use it to query graphs using SQL and the Cypher subset. 

Michael Malak - Bio

Michael Malak is the lead author of Spark GraphX In Action and has been developing Spark solutions at two Fortune 200 companies since early 2013. He has been programming computers since before they could be bought pre-assembled in stores. 

NLP Walkabout - Abstract

(Live stream available)

Natural Language Processing (NLP) is a broad topic encompassing many different problems requiring very different areas of expertise. And in some associated domains, even the initial problems are difficult to define. This talk will survey a few selected NLP topics at a high (and hopefully entertaining) level. This is not a rigorous how-to, but rather an informal walkabout to appreciate some of the different challenges within the field of NLP. 

Rob Oberbreckling - Bio

Rob Oberbreckling’s interests include applying software development and data science to problems in cognitive science, natural language, and social science.  Rob has also led efforts in retail embedded IOT sensor development, digital video and audio stream analysis for the NFL, and spoken and written communications analysis for automated essay grading and for predicting human behavior.    Rob is currently a Consulting Member of Technical Staff at Oracle. 

• Go into the building, down the short flight of stairs, then turn around and to the left down another flight of stairs. That's Spark Boulder!

• Python's scikit-learn package provides a consistent framework that makes applying many standard machine learning algorithms fairly straightforward. It is certainly one of the reasons that data analysis is becoming so popular in Python!

  This tutorial will give an overview of the types of problems that can be addressed using scikit-Learn. We will use several code examples to explain some of the basic concepts of machine learning, including classification, clustering, and dimensionality reduction. 

  Here's the GitHub repo we'll be working from.https://github.com/mlunacek/meetup_data_science_2016. Come to this event with a laptop, as we will be working on code!

  See you at the event!

If there's a new HTML5 element that we should be using, here's your chance to show us how you're using it in your application.

To start your inevitable rise to Lightning Talk Fame and Fortune, just send your talk title and a quick paragraph describing what you plan to cover to me -- scott@thirstyhead.com. 

"Adaptive Web Design in Three Popular LAMP CMSes" by Tom Hartung

I would like to present the work I have been doing lately, with using device detection to determine whether the user is on a phone, tablet, or desktop browser.  I have been adding this capability to the three LAMP CMSes, Wordpress, Joomla, and Drupal (both 7 and 8).  The code uses options set by the administrator to customize the markup, specifically the headings and menus, for each type of device.  The options also determine whether to include jQuery Mobile, adding it and HTML5 data attributes as appropriate, to the markup sent in the response to the target device. 

"Nintendo Gameboy emulator on a Raspberry Pi" by Jeff Stephens 
A Chrome Extension watches a chatroom for new commands, passes them to a local web server which calls a local Linux utility to execute keyboard commands in the emulator window. The game video is shared via Chrome's Screen Sharing feature and streamed over a videoconferencing platform using WebRTC and written in Angular 1 (which is the product I work on during my day job).

"Angular, The Game Engine?" by Stuart Urback 

Often when we think of building web-games we imagine using a unity plug-in, canvas, or using some sort of "game engine" to render a 2d or 3d game in a window.  But systems like Angular that allow for easy management of states and routes can duplicate its own sort of game engine/methodology.  I've used this to create my own game "Actor Battle" and will go through how I created a game loop and rendered the results in angular.

"Theming Bootstrap with Bootswatch" by Geoff Filippi

We all want mobile first responsive web apps that are battle hardened, but no one wants their app to "look like bootstrap". We will discuss how to get all of the advantages of bootstrap, with a solid customization workflow that scales to a large team. Bootswatch is a well thought out Bootstrap customization utility that gets you going quickly without compromises.

• All proceeds from this day-long, hands-on workshop go to the HTML5 Denver User Group. By attending this workshop, you're not only getting a deep dive into Angular 2 -- you are supporting our free, monthly meetings. Thanks!

  Angular 1 was released in 2009. That longevity and stability made Angular one of the most popular and reliable web frameworks in production today. But 7+ years is an eternity in Internet-Time, and big changes are coming with Angular 2.

  Angular 2 is a dramatically simplified and refined update, but it's radically different than Angular 1. No more scopes, controllers, or directives -- Angular 2 is now "All Components and Services, All the Time."

  The upgrade process -- sadly -- isn't simply swapping out a <script src> from Version 1 to Version 2. There are massive changes underfoot. You'll most likely start with a new programming language (ECMAScript 6 or TypeScript), and make some correspondingly non-trivial changes to your development tools (BabelJS for transpilation and polyfilling, JSPM for package management, SystemJS for your new ES6-compliant module loader).

  In this day-long workshop, you'll get the opportunity to take Angular 2 out for a spin and get some serious hands-on experience with it.

  Course outline: 
  Your First Angular 2 App
  ------------------------ 
  In this section, you'll hit the ground running. You'll write your first Angular 2 app and explore the various parts of a working app.

  
  Working with Components
  ----------------------- 
  Components are the basic building block of an Angular 2 app. In this section, you'll write a few more Components and get them on speaking terms with one another.

  
  Routing in Angular 2
  --------------------- 
  Angular 2 offers (yet another) new Router. This one is far simpler than what you may have grown accustomed to in Angular 1 -- it simply loads Components into named slots based on the current URL. In this section, you'll see how easy it is to set up declarative routes in Angular 2.

  
  Introducing Structural Directives
  ----------------------------------- 
  If you wrote your own custom Directives in Angular 1 to create new HTML elements, Components are a dramatically simplified and streamlined way to accomplish the same thing. (As a bonus, you can finally forget the word "transclusion".) But Directives haven't gone away -- they are simply called "Structural Directives" now. In this section, you'll take a couple of the new ones out for a ride -- ngIf, ngSwitch, and ngStyle.

  
  Building Forms in Angular 2
  ----------------------------- 
  Forms are a big part of web development, and Angular 2 introduces a whole new infrastructure for dealing with HTML forms. In this section, you'll learn about Controls, ControlGroups, ngForms, validation, and much more.

  
  Working with Services
  ---------------------- 
  Chances are your Angular 2 app doesn't run in isolation -- you probably are making AJAX requests for remote data from somewhere. In this section, you'll learn how to bring the outside world into your app, one HTTP GET request at a time.
