.NETQuality assurance
I started using unit tests eight years ago and failed miserably. It took me two years and the right company to start over and learn how to properly use unit tests and TDD as development tools. But it wasn’t always clear sailing. As I progressed, I found more than my fair share of pitfalls and blind alleys, as well as a fair amount of success. In this talk, I’ll cover the essential facts I learned over the years about unit testing.
MobileQuality assurance
Mobile testing is getting harder: more devices, multiple operating systems, higher quality expectations, and shorter development cycles. Much of mobile app testing is manual, and moving to automation is a requirement. But where do you start? Do you know who is the typical user and how the app is used? How do you know which devices to test? How do you measure app performance? Come and learn a 7-step method and the tools to improve the testing process.
HTML & CSSMobile
The AMP (Accelerated Mobile Pages) project is a new open source initiative that allows you to build mobile HTML pages that load nearly instantaneously. The guidelines laid out by AMP are mainly restrictive, leading to a simpler, faster mobile web. This technology is taking off, and Google will be rewarding websites that use AMP with an SEO bump. In this talk, join the big names in technology today by learning how to write AMP HTML.
Node.jsRuby

This will involve indexing real world logs from applications. This talk will also explore how to re-structure data that already exists within Elasticsearch via re-indexing. Listeners will learn how to take their own logs and extract meaningful visualizations using The Elastic Stack.
PythonMachine learning
From implementing new research to validating results, running machine learning experiments can often be a process of trial and error. TensorFlow is an open source computing framework that places state of the art algorithms and tools into developers' hands, allowing you to rapidly iterate experiments, monitor their results, and scale into production. We'll show you how to train machine learning pipelines from conception to release with TensorFlow.
HTML & CSSPython
From “Space Oddity” to “Blackstar,” Bowie inspired us with his diverse personas. What can IBM Watson reveal about those iconic characters through natural language analysis? That's the mission of Ziggy, a little Python app that builds a database of songs, and digs into the style and tone of writing within them. This session explores the findings and shows how it works. We'll consider real world use cases and future iterations.
Python
What are closures all about anyway, and why is there a new keyword in Python 3? In this talk, we'll look at what closures are, their history in the Python language, what the Python 3 nonlocal keyword is about, and examine how closures are idiomatically used (and avoided) in Python.
Databases
Very few developers receive training in Structured Query Language (SQL), but they are expected to have highly efficient database queries. Add in bad data normalization and lightning quick applications suddenly crawl. This session is a must for new developers who do not want to suffer hours of extra effort working with their data. We will cover how to avoid situations like the N+1 Problem, primary key violations, improper relationships, and more.
HTML & CSS
Building linear layouts in CSS has been hard. Tables are bad, inline-block has quirks, and floats are insufficient. Thankfully CSS Flexbox enables us to solve our layout problems elegantly . While the specification has been around for over four years, increased browser support has finally pushed Flexbox mainstream. Let’s deep dive into Flexbox: what it is, why you should use it, how it’s configured, and where it’s most useful.
PHP
Full frameworks are heavy, slow, and internally coupled. On the other hand, microframeworks can lead to “not invented here” because of missing functionality, or a minefield of tradeoffs connecting to other components.
Zend Framework 3 features separated components, and is blazing fast, with skeleton apps to leverage as a PSR-7 middleware, or as a full stack framework, with highly connective APIs. This will get attendees up and running quickly.

Ruby
Ruby is 21 years old this year. Despite Rails being a popular tool that startups use, and despite the lushness of the RubyGems ecosystem, there are plenty who would declare Ruby as being on the wane. However, at Lighthouse Labs, we are still convinced that Ruby is the best vehicle for students to learn OOP programming. In this talk, we will discuss some of the strategies used to demonstrate the power of Ruby to a new generation of developers.
Security
To protect our users and provide reliable, useful services, we need developers, engineers, SREs, information security, and the business savvy to all pull together. Rather than rely on onerous and (seemingly) abstract security recommendations, we need to understand what we're up against: who is attacking us? What are their motives, their capabilities? Let's threat model! Learn how to assess what defenses are meaningful and which are a waste of time.
Databases.NET
When we were asked to move our SQL migrations to under 5 minutes of client downtime we said, “Impossible.” But we actually managed to achieve 0 minutes. In this talk, I will share how we achieved large scale (200 developers and terabyte sized databases) fully online migrations every month to our production SQL Server databases. We will cover the scripting changes, DB validations, and CI improvements we introduced to make this possible.
Whether you're building a backend or a frontend application, creating an API or consuming one, it’s helpful to understand the basics of HTTP.

PerformanceQuality assurance
We all understand the need for functional testing with every build and release We write unit tests and QA creates user acceptance and other functional tests. Often, performance testing is put off until later, maybe even until the app is in production. Why isn’t performance testing a part of every build? With today’s performance and continuous integration tools, performance can be continuous.
Architecture & design patternsRuby
Music and code. Two things that outwardly seem very different. And yet, whether performer or programmer, you have a number of the exact same considerations. This talk will demonstrate how approaching both roles with the same mindset can improve your performance in both.
Databases

DevOpsPHP
Developers love to "automate all the things,” but where to start? What tools exist, and what can be automated? Without unit tests, can it still benefit to automate? We will show how a PHP application pulled from Git, complete with unit tests, composer dependency management, and package creation, can be repeatedly deployed flawlessly using Jenkins. Then see how "Dev" and "Ops" are supported if the application breaks through automated rollbacks.
Machine learning
Machine learning is amazing, but to get accurate predictions you will need to spend time working with your data to get the best possible outputs. Like the old adage says: garbage in garbage out! So if you are trying to learn more about machine learning, stop by and learn the basics of preparing your data for machine learning. We will start with a real world dataset and transform it to get more accurate predictions from our training model.
Python
Python is one of the most popular programming languages, and one of the most flexible. You can create pretty much any type of code you need: object oriented, procedural, functional... And it can be used to create any type of application, and is used in many big data scenarios. You can also get up and running in a short period of time if you’re experienced with another programming language.
Mobile
If you consider yourself a web developer first and a complete N00b in mobile, this hands-on talk is for you. Unlike other hybrid approaches (e.g., PhoneGap/Apache Cordova), React Native allows developers to build truly native mobile apps. What’s even better, developers can do it using familiar web dev tools like Chrome DevTools and JavaScript. On top of that, you get hot reloading-- meaning there’s no need to wait for the compilation!
RegEx is scary. At least, if you ask Google, that's what you might think (257,000). And slow (441,000). In fact, regular expressions are neither of these, and indeed are a powerful tool in your utility belt.
In "RegEx Is Your Friend", Liam aims to provide some real-world and usable examples of how it can be used in a way that's fast, explaining how the different parts of regular expressions work and execute to make it understandable for all.

PHP
Have you ever had to maintain a 15-year-old application? Dead code everywhere, database queries in between HTML tags, and some pages still in PHP 3. This strategy-level presentation will lead you through a progressive rewrite, from very old legacy to the latest shiny version of PHP. Learn how to automate legacy testing, how to seamlessly jump between the old and new parts, and how to overcome other challenges that arise from dealing with legacy.
PerformanceRuby
Ruby developers have known for years that our beloved language is one of the most joyful to write. And yet, "Ruby can't scale" seems to be a daily article on Hacker News. In this presentation, aimed at intermediate-level Ruby developers, I'll present some tips and tricks that we've learned at New Relic writing Ruby services that scale to hundreds of thousands of requests per minute.
DatabasesPHP
Where is the truth in sentences like "ORMs are slow" or "SQL is insecure?"
We will walk through the reasons that shaped ORM architecture, their potential and limitations.
After this talk, you will be in a better position to choose the best fit for you and your next application.

JavaScript
ECMAScript 6 is the new version of JavaScript available in the engines of our modern browsers and servers. Many of its features are just a little syntactic sugar to help make our code clearer and more concise. Learn how to use arrow functions, destructuring, rest parameters, and other sweet ES6 features.
PHP
Symfony is a powerful and very flexible framework for building web applications. Symfony is also a collection of base components that you can use separately in any PHP application. This modular nature allows many frameworks to build on top of it, the most notable being Drupal 8 and Laravel. In this talk, I will give an overview of the fundamental Symfony components and show how to use the full stack framework.
.NET
Tired of projects where the wrong thing is tested? Finding TDD too time-consuming or too hard? High test coverage and your users still find bugs? Don’t understand if your tests are unit, integration, automation? InVEST in your future; come and discover how to write those tests that matter using this approach, based on a lifetime of test-driven development and unit testing practice. The hyperboles are included for free.
Management
The Four Pillars of Management will cover Time, Budgeting, People and Stress. For Time, we will switch the paradigm from worrying about having enough of it to assessing our daily habits. Budgeting will cover the latest techniques to ensure actual results are not a surprise. People will include the latest hot topics for management. Stress is either Eustress (positive) or Distress (negative); let's focus on the former and fuel our successes!
HTML & CSS
CSS Layout in 2016 is a mess of hacked together methods using techniques that were never designed for complex web and application layout. However change is in the air, brought to us by specifications such as CSS Grid Layout, Flexbox, and the Box Alignment Module. In this session Rachel will introduce these specifications, explaining how they fit together to create a new system for layout.
Quality assurance
We all make mistakes. As much as we try to write flawless code, every now and then an error slips through. In order to reduce the number of mistakes, we perform code reviews to ensure the code meets certain standards and to see if the feature was properly implemented. But how do you do a good code review? How do you handle technical discussions? How do you keep your reviews focused and your discussions relevant? Attend the talk and learn the answers.
Architecture & design patterns
The talk will cover exactly what the state pattern is and how it's used in a game. Then we'll be discovering what this can do for us in the world of web applications. Following that we'll take a brief look at the state machine to see how it's different from the pattern and why it's useful to us. We’ll put theory into practice throughout the talk by continuously showing examples. And we’ll even include some live coding.
Architecture & design patterns
Have you heard about type theory and always wanted to understand the principles behind it, but always thought it was too complicated since it has a lot of Lambda Calculus and algebra? Type Theory is a concept that is sometimes regarded as boring or too difficult, and this talk will show that any developer can understand those principles and maybe apply them to improve their decisions on architecture.
PHPQuality assurance
How often have you rewritten your unit tests from scratch just because the code it was testing evolved slightly? In this session we will explore some unit testing techniques from other languages to produce more robust tests in PHP. You’ll never have to send your unit test to the trashcan again.
DocumentationPython
This talk will cover the internals of how a system for documenting software works. This talk will include specific examples from the Sphinx documentation generator, and cover the concepts they use to make documentation generation powerful.
The talk aims to impart high-level understanding of the concepts around documentation generation, which will be applicable to most documentation tooling, whether it be Commonmark, RST, or Asciidoc.

DatabasesPerformanceRuby
N+1 queries are prevalent and problematic in almost every web application. However, they are a silent performance killer. Often they go under the radar and their existence will not cause a web application to grind to a halt. There exists standard ways to eliminate them but they fall a little short. This presentation will dive into a way to detect these the problems as well as improvements to the known solutions.
Architecture & design patternsPython
Elm, Figwheel, Redux, and other environments that carefully manage state have popularized reliable, straightforward implementations of undo, hot code reloading, and time travel. Although these techniques are harder to implement in more traditional environments, sometimes their power is worth it. We'll walk through some hacky strategies: saving state with fork(2), replaying operations to rebuild state, and deeply copying webs of mutable objects.
AccessibilityHTML & CSS
n this session we will jump right in and use ARIA and HTML5 to create modern, accessible web applications. Using real code examples, Billy will demonstrate various techniques developers of any skill level can implement into their existing code to improve accessibility. Starting with the basics and working up to some more advanced examples, attendees will learn how to start using ARIA right away.
We're no strangers to VoIP. You know XML, and so do I. A full implementation is what I'm thinking of. You wouldn't get this from any other talk!
I just gotta tell you how to code this, gotta make you understand…
Learn how to set up VoIP; how to tear calls down; how to run high availability, and stateless.
Learn how tech makes you cry; how to upgrade on the fly; how your call will be monitored for quality assurance and training purposes.

JavaScriptMobile
Any developer with a modern Android or iOS device and a cardboard viewer can get started making unique experiences relatively quickly. This introductory talk will go over the basics of three.js and the WebVR Boilerplate and will discuss how to to use standard web development practices to bring these experiences quickly across devices.
PHP
PHP isn't the same as it was 5 years ago. Now with the release of PHP7, it continues to evolve. If you haven't looked at PHP in a few years, you won’t recognize it! Namespaces, SPL, Traits, Closures, Scalar Type Hints, and so much more was added to the language in recent years. Not to mention ecosystem additions of Composer and PuPHPet. Join us for a whirlwind tour of what PHP has become.
HTML & CSSPerformance
Today we have CSS specifications for animation and transitions, complex layout, custom properties and much more. In addition to the breadth of modern CSS specifications, our evergreen, auto-updating browsers sneak in new features with every release.
In this talk, I’ll be taking a look at some of the things that CSS is capable of, some of which you might think you need a JavaScript framework or at least a pre-processor to achieve.

JavaScriptNode.js
Node.js can be a powerful platform used in the right situations, but it also has more footguns than PHP does for new developers. Asynchronous programming style, concurrency issues, error handling, the event loop, and no default timeouts for HTTP requests or network calls will give new developers more than their fair share of troubles. This talk gives a thorough introduction to node.js and the event loop model, and covers common pitfalls to avoid.
