Your mission, should you choose to accept it, is to support an application built on an older framework. Refactoring isn't an easy option. The code is untested and nowhere near best practices or standards. In this session, we'll talk about strategies to incorporate modern PHP coding practices to add features and functionality and retiring the older code in pieces. We'll review specific examples and code from a real project where we bootstrapped a legacy application that needed a lot of help to become useful to its users and simpler for developers to maintain. We'll talk about strategies to leave the existing code in place until the new code is ready to replace it in whole or in pieces.
So what does a database do with a query? How do you avoid the N+1 problem, SQL injection, or just poor database performance? If you are new to programming and want to learn how to efficiently learn how to use a database then you need to be in this session, You will understand how a database server processes a query, why you need to think in sets, why the common problems occur, how to filter user data, and get a very good overview of writing efficient database queries. This tutorial is designed to get novice developers started on the right path to working with a relational database.
Computers have one job: to read and process data. One job, and sometimes they still need help!
Structured data puts you in control, ensuring that search engines and other parsers aren't misreading your information. Get your events recognized as events, your business address as a location, and those product reviews working to attract customers!
Implementing good, structured data is also the first step into the Google Knowledge Graph, the Holy Grail for content marketers. Better yet, with modern standards, it's easier than ever before to get started!
Today’s society is filled with devices, apps, and software that make communication easier and faster. But are we communicating with others in the most appropriate and effective way? Are we causing more problems and headaches for ourselves by only communicating in 140 characters at a time? In this talk, we will discuss the elements of interpersonal communication, the pitfalls of various methods of communication, and learn tools and strategies to put into immediate action. Attendees will leave with six action items to immediately use and improve their communication.
Arrays are beautiful in PHP. One can map them, reduce them, filter them, foreach them, and use them in generators. Strings, on the other hand, are mere shadows to the Array. One can, uh, input and output Strings, and, when brave, manipulate them. What makes Arrays so awesome and Strings so dull? Iterators.
In this talk, we’ll look at the modest origins of the String and the basics of the Iterator. Then, we’ll look at how we can make the String as awesome as the Array through the use of iterator interfaces.
By the end of this talk, you will know the origins of the PHP String and you will be able to extend your knowledge of iterating through a String to be able to iterate through customized objects.
Ever kill a bug only to have it resurface later? How about that last intermittent bug you had to trace down? Looking forward to fixing it again when it pops back up?
If you hate reanimated bugs then this session is for you. In this session, we will discuss the why and the how of building regression testing into your tests using the Codeception testing framework.
Join me, let's hunt some zombie bugs. (Weapons not required)

Do you hate the Facebook API? We all do as well. So stop writing your API in their footsteps. In this talk we will walk through how to construct a RESTful API, what makes an API your users/developers will love, and why you should eat your own dog food with API Driven Development.
There are various access control models, each with a specific intent and purpose. Determining the ideal model for an application can help ensure proper authorization to application resources. Each of the primary models will be covered, including the MAC, DAC, RBAC, and ABAC Access Control models. Examples, challenges, and benefits of each will be discussed to provide a further insight into which solution may best serve an application. Application sensitivity, regulations, and privacy may drive which model is selected.
It used to be that crawling social media required some creative coding, a deep understanding of links and relationships, and a finely tuned BS detector. With machine learning becoming common place, it turns out you only need the first two.
Considering information in isolation never gives us a complete picture. As we supplement what we know with what we discover with what inferences and patterns our models can detect, what we know and what we KNOW becomes starkly different.
In this session, we'll dive into a multi-year project that has used social media and other public data sources to uncover hiring patterns, stealth startups, and even pending legal action.
We've all been to the talks about the tools for test driven development. But TDD is not just about writing tests, it's about driving development through testing. There's a very specific process of TDD with red, green, and blue phases. There's also different patterns, like outside-in or inside-out. In this talk, we will focus on these practices by TDDing a common data structure from start to finish. Attendees will gain experience and leave with tips to help them practice TDD in the real world.

Trying to understand a complex function full of nested loops and conditionals is like trying to read a "choose your own adventure" book from front to back.
In this whirlwind tour of programming with collection pipelines, you'll learn how to use functional programming ideas to break down complex code and abstract hidden duplication behind expressive higher order functions.
Together we'll refactor ugly, complicated spaghetti into a series of simple, elegant transformations; free of loops, complex conditionals, and temporary variables.
Never write another loop again.
Your customer calls, your project manager assigns you an issue, your open source project gets a pull request, or your boss emails you – “There’s a problem…” As computer genius and wiz kid you are expected to solve all of these problems because that’s what you are – a problem solver. Well, sort of. Kind of. Not really. Software engineer, sure. Frontend developer, yep. But when was the last time someone gave you a complete, perfectly described problem and you solved it completely? Do you even remember being taught how to recognize, describe, and solve problems? How do you even know if it is really solved?
In the talk Problem Solved-ish we learn again or perhaps for the first time how problem solvers think, how our skills our empowered by our knowledge and understanding of the problem itself, and how solutions finally reveal themselves and the problems really do get solved. We take a look at the five C’s of debugging. We show the five Q’s of the Problem Solving Method. We demonstrate how testing can improve your confidence, your problem describing skills, and even your solution making skills. We will explore the business angle of problem solving and optimization by constraint based decision making and problem solving. Finally you will have a framework for making sure that it’s “problem solved.”
Come see a fast-paced introduction to Elm. We'll walk through some of Elm's most notable features, what the Elm Architecture entails, and learn how to model and implement a simple application with using static types and a functional mindset.
You've heard about dependency injection and inversion of control. Everything seems easy at first and you've found a container or two to help make your life easier. Until it isn't anymore. Suddenly you've found yourself managing complicated YAML, XML, or PHP container configurations. Making any change to your classes dependencies seems like a chore and any time you add a new class to the system you dread the inevitable configuration container configuration wiring blues.
Life doesn't have to be this way! In fact, life isn't this way for anyone who uses an autowiring container like Laravel's. Far from the most publicly marketed component, Illuminate\Container handles a lot of the magic that makes Laravel so much fun to use. Find out how you can use Laravel's container in almost any project! See how autowiring can free your mind from having to manually configure ever little dependency. Learn how you, too, can learn to stop wiring your dependency injection container and love Laravel's container!

Humans learn most effectively through pain, like being shocked by a power outlet or touching a hot iron. The same reaction can be found in technology, but how can we attribute this to programming while minimizing the most painful mistakes? Adam Culp will share his experiences of the ongoing journey to become a professional developer, and highlight techniques used to reduce the pain and still reap the benefits. And for those times when the pain is inevitable, how can we fast-forward to enlightenment.
