    Grunt From The Ground Up

    by Brian P. Hogan

    Modern web development requires managing CSS, JavaScript, HTML, and other assets, and things can get out of hand quickly. Grunt has become the standard for managing all of the tasks related to modern development, from concatenating files to minifying files for production. Unfortunately, most documentation on the Web focuses on how to cut and paste configuration files together. That’s not very helpful.

    In this talk you'll learn how to use Grunt for a variety of purposes as we explore how it all works. We’ll cover how to develop Grunt tasks, how to work with files, how Multitasks work, and how to use Grunt and its plugin system to manage the development of a single page app that uses CoffeeScript, Sass, and Angular. When we’re done you’ll know exactly how Grunt works so you can use it on your own projects right away.

    Hands-on Haskell 101

    by Chris Wilson

    I've given a few talks about Haskell at previous TCCCs, but one thing that kept coming up was that people would say "hey, I want to do some hands-on stuff."

    Well you're in luck. I'm going to go through a quick hands-on intro to Haskell. Bring your computer and get ready to hack. I'll teach the basics of programming with Haskell. You'll learn the data structures, functions, and other tidbits necessary to start really writing code. Come see for yourself what everyone's been talking about!

    I'll assume only a basic level of computer programming. If you're comfortable in another language like JavaScript, Python, Ruby, C#, or Java you'll be fine. Even if you aren't quite comfortable, you should still be able to follow along and maybe you'll even be at an advantage, not having to ignore all you know about imperative programming!

    Don't : How Web Components will Redefine the Web

    by Dan Callahan

    Create your own HTML tags with Custom Elements!

    Take your hands off the handlebars.js with HTML Templates!

    Seamlessly reuse front-end code with HTML Imports!

    Shine light on the Shadow DOM!

    In this session, you'll learn how the brand new "Web Components" standards will help you "define widgets with a level of visual richness and interactivity not possible with CSS alone, and ease of composition and reuse not possible with script libraries today." In other words, you can finally encapsulate and extend HTML itself, and it's awesome.

    Plus, we'll make a brand new <custom-blink> tag in the first five minutes. The Web will thank us later.

    Regex Searches: Ain't Nobody Got Time for That!

    by David Shepherd

    Developers are busy people, running from sprint to sprint, with little time for self-reflection. They don't notice how often they mutter "..how'd he implement that.." or "..where's that method that does X?" They don't notice that the search tool they use to answer these questions is from the 1960s. They don't even seem to notice that 90% of these type of searches fail! Fortunately, a developer turned researcher did notice, and has dedicated the better part of the last decade to eliminating this quiet productivity-killer.

    In this talk, I'll use both video examples and a massive repository of real developer activity data to prove that the typically-used regex searches waste a significant part of your day. Yet this talk won't dwell on the past; it focuses squarely on a better search future. I'll provide a tour of Visual Studio's many built in searches, demonstrate two search tools available as extensions, and provide guidelines for better searching. By attending this talk you will become a more effective searcher, a skill that is surprisingly fundamental to software development, and I estimate you can eliminate 10-30% waste from an average sprint.

    Big Data in Real Time with Elastic Search

    by Eric Brandes

    You have mountains of data. Users demand instant rich interactions. Businesses need deeper insights from that data. How can you group, search, and drill down into big data in real-time without crushing the database or writing cumbersome map/reduce jobs?

    Elastic Search is the distributed, open source answer to your problems. It’s a powerful tool that slices and dices massive data sets in real-time. In this talk we’ll see some live demos that showcase the power of Elastic Search, but would melt a traditional database. Things like full text searching, nested groupings, and real-time analytics. We’ll also discuss when and why you would use Elastic Search over more conventional alternatives.

    The Art of Node: An Introduction to Node.js

    by James Greene

    By now, most developers have heard of Node.js — the dominant "server-side JavaScript engine" — but many still haven't worked with it. Come listen, learn, and play along as we explore the world of Node.

    Attendees can expect answers to the following questions:

    • What is Node, really?
    • What is Node good for? What is Node exceptionally great for?
    • Why should I care about Node? Isn't it only used by "hipster" startups? I work in the enterprise!
    • How do I use Node?
    • How should I structure my Node application?
    • What is NPM? How do I use it?
    • Is there an analogous Node module to my beloved "Library XYZ" for .NET (or other languages/runtimes)?
    • Can I only use Node on the server-side?
    • ...and so much more!

    Attendees should have basic familiarity with the JavaScript language and how to use a command line (terminal).

    Angular.js Testing

    by Jason More

    The first time you you write tests for any new framework can be challenging. How do you setup the tests? How do you run them efficiently? What about mocking upstream callers? Is any of it really worth it?

    During this talk I’ll show you how to write unit tests for Angular controllers, directives, services, along with browser components such as setTimeout and making HTTP calls. I’ll be writing my tests in Jasmine, and continuously running them in Karma. Then we will wrap up by writing one end-to-end test using Protractor.

    Grails in the JavaScript Age

    by John Urberg

    We are in the "JavaScript Age" where more and more web applications are making heavy use of JavaScript on the client. Many of us are still writing "LAMP Age" applications where we generate pages on the server side using our favorite MVC framework. When we develop our server side code, we know we should be using good engineering practices such as modularity and unit testing. As we continue to add more and more JavaScript, we should be applying those principles to our JavaScript code. This session will show how to refactor your JavaScript code to incorporate these principles using only PhantomJS and your framework's build tools. The presentation uses Grails but the concepts should apply to your favorite server side framework.

    Make Your Own Print & Play Card Game Using SVG and JavaScript

    by Kevin Hakanson

    Want to leverage your creativity, love of board games, and web platform experience to do something different? Turn your imagination into a Print & Play card game using only a modern web browser, color printer and text editor.

    This session will use the Scalable Vector Graphics (SVG) image format and JavaScript programming language to make a deck of cards for a simple game. Creating a few cards in graphics software like Inkscape is one thing, but what about 50 or 100 cards? What happens when you need to update them all? That’s the value of generating your SVG using JavaScript.

    We will start with a blank screen, adding color and graphics elements like lines, shapes, text and images. Learn about container elements and defining content for re-use. Understand how units in the SVG coordinate system can transform our on-screen creation into an 8.5 by 11 inch printed page (or PDF). SVG examples will be both in their native XML format and created from JavaScript using Snap.svg, an open source library from Adobe designed for modern web browsers.

    You will leave this session with a basic knowledge of SVG concepts, how to programmatically generate SVG using JavaScript, and how to make your SVG creation printer friendly.

    Mobility: Designing & Developing for Tablets and Smartphones

    by Lou Miranda

    Mobility isn’t just about smartphones anymore. Since the advent of the iPad, four years ago, tablets have sold in the hundreds of millions. Recent studies on consumer spending for the 2013 holiday season demonstrate that much mobile commerce occurs on tablets. And as a productivity device, a tablet can be much more useful than a phone-sized device.

    But is designing and developing for tablets too difficult? Are there reasonable ways of cutting costs when developing tablet apps? How much visual design and code reuse is there in “universal” apps that run on phones and tablets? How different is a tablet from a laptop, and how different is it from a phone? All this and more will be discussed as we cover one of the leading trends for mobility in 2014.

    Making Massive Apps Mini: Google's Closure Compiler

    by Nate Young

    Google's Closure Compiler is more than just a run-of-the-mill JavaScript minifier, it's a whole-program optimizer with a number of tricks up its sleeve: dead code elimination, inlining, a rich standard library, and even type-checking. It is, like lots of tools Google throws over its high ivory walls, a bit intimidating to get started with, though. This talk will show you how to get up and running with Closure, how to integrate it into a one-touch build process and the ins-and-outs of its most useful features. I'll show you what I did to take a rich, single page app with 456K of JavaScript spread over 123 files and turn it into a single 74K file.

    Quest for the Holy Gradle: Software Build Top-to-Bottom

    by Nick Stevens

    Historically JVM build tools have been locked in the JVM playground - languages other than Java need not apply. Gradle is a blossoming build tool that changes that - providing build capabilities for everything from C to JavaScript, Scala to Java.

    This session is going to be heavily based on doing: creating a simple project that spans Java, Groovy, JavaScript, and CoffeeScript. I'll show you how to perform all steps of a build and assembly process with a single Gradle command, from a workstation with only the JDK installed.

    An Optimistic Approach: Utilizing Snapshot Isolation in SQL Server

    by Paul Timmerman

    Readers block writers and writers block readers. You’ve got to write your T-SQL code with that in mind, right? Not necessarily! By utilizing the Read Committed Snapshot database option or the Snapshot Isolation level within SQL Server, you can dramatically increase concurrency for your database applications. After a high level overview of SQL Server isolation levels, we’ll spend the majority of this session discussing the implementation of optimistic concurrency control within SQL Server. We’ll look at the benefits and drawbacks of using an optimistic isolation level and discuss use cases where it may or may not be appropriate. Come learn how to put one of the more powerful, but least understood, aspects of SQL Server to work for you!

    Systems Inferno: Automation from Hell to Heaven

    by Richard Isaacson

    A conversation of the Systems journey from Operator to Architect. We will cover techniques and tools that apply to each of the job title stages. In addition we will talk about how systems automation isn’t confined and is becoming relevant to the application development life-cycle. While this talk is very Unix family focused the general topics should apply to any operating system. Management is welcome to attend as the talk may give them an idea of what their teams should be doing and how to support their team.

    We will not be dwelling long on on any one technology stack as we will favor a strong overview of what the journey should look like. Executing commands from notes, from memory, in scripts, as a part of tools, and via push button self-service will be our major mile markers.

    Cross-Platform Mobile Development with Xamarin

    by Vince Bullinger

    Creating enterprise-caliber mobile applications presents a myriad of problems. One of those problems is having an entirely separate team of developers with an entirely separate skillset for each platform on which you’d like your app to work. Cross-platform mobile development seeks to alleviate this problem.

    In this talk, we’ll take a deep-dive into the Xamarin framework. We’ll take an in-depth look at the Xamarin approach to solving this problem, as well as briefly touch upon native development and other technologies’ cross-platform solutions and when each one may be appropriate to use. We’ll also go over some best practices for Xamarin development for the enterprise environment and take a look at tools associated with Xamarin.
