Iowa Code Camp - Fall 2017 - Sessions


Registration is now open! Register now! Registration will open about a month before the event.

  • "So, who's gonna tell 'em?"

    The talk about "the talk" that nobody wants to talk about. The growing emphasis on "Individuals and Interactions" yields tremendous rewards, but not without risk. Teams who work together more increasingly find themselves in situations where they NEED to have sensitive and high risk conversations, but don't always know how to approach it. Everyone knows about some of the biggest challenges that face a team. They are also aware of the many ways the corrective conversation that can go awry. These conversations are often indefinitely delayed. Opportunities for growth are missed and resentment grows. Learn how to be the agent of change your team needs with techniques and practices to help you master the crucial conversations.

    9:00 AM - 10:15 AM : Room 107 : "So, who's gonna tell 'em?" (Level: 100)
    Speaker: Dustin Thostenson

  • "We'll do it live!": Monitoring and Debugging in Production

    That big "P" word: Production. That new piece of shiny code you just wrote with a hundred percent test coverage goes ka-put once it's deployed once deployed there. What broken, and why? Sometimes the errors are a little more subtle, lying and growing there until you reach the right conditions. Either way, when users experience problems, it's not good. Maybe we need to check our assumptions a bit and figure out how to lower the risk if things go sideways. We'll go over my experience in a highly regulated industry to apply the OODA loop, continuous delivery, ownership, and observability to embrace failure to lower risk of production incidents.

    3:45 PM - 5:00 PM : Room 114 : "We'll do it live!": Monitoring and Debugging in Production (Level: 200)
    Speaker: Luke Amdor

  • A DSL for Your API

    Have you ever wanted to allow your users to be able to write scripts to execute actions within your application? Have you ever wondered how applications that do this accomplish it? Have you ever been sitting around with too much time on your hands and needed something interesting to think about? If so, then this talk is for you. During this talk we'll look at an app with a simple, easy to Grok API, and build up our own scripting language using the ANTLR4 Parser/Lexer generator, with which to drive it. All this, faster than you can say "The Dragon Book".

    2:15 PM - 3:30 PM : Room 108 : A DSL for Your API (Level: 200)
    Speaker: Greg Sohl

  • An Advocates Guide: You Just Got Hired. Now What?

    Great! You landed a new job and are now on a team of developers. Who is bringing you up to speed? What are you doing in your down time? What questions do you ask? This talk aims to demystify those questions, decrease imposter syndrome and give less experienced developers a fair chance at becoming leaders. Juniors to tech leads will find this talk valuable.

    2:15 PM - 3:30 PM : Room 112 : An Advocates Guide: You Just Got Hired. Now What? (Level: 100)
    Speaker: Michael Liendo

  • ASP.NET Core 2 Fundamentals

    In this talk we'll go over the fundamentals of ASP.NET Core 2 and what you need to know to get started and be productive. We'll discuss the latest changes and improvements made in ASP.NET Core 2 over the 1.x versions including the brand new Razor Pages.

    10:30 AM - 11:45 AM : Room 113 : ASP.NET Core 2 Fundamentals (Level: 100)
    Speaker: Scott Sauber

  • Basics of the Mobile Market: From Prototyping and Design to Delivery

    Companies like Google and Apple have made it really easy for any developer to create an app. The tools are great, the community support is amazing, and the tutorials are endless. This leads to a lot of amazing apps, but it also means the mobile market is crowded. There are a ton of apps out there and they do almost everything you can think of. How can you design and make something that will get noticed, and once you do, how can you maintain that momentum and build a product or a brand that is truly unique? I will cover the basics of getting started with your idea, including the importance of UI/UX as a base for your app and the tools for developing an Android app. Then I will go into the release process and how to convert views to installs and retain those users for the life of your app.

    10:30 AM - 11:45 AM : Room 106 : Basics of the Mobile Market: From Prototyping and Design to Delivery (Level: 100)
    Speaker: Luke Klinker

  • Beginner's Guide to Refactoring Code

    Imagine that you have just started working on a large established legacy code base with little test support. Documentation doesn't exist and the development culture has been of a ‘git er done' mentality, so there are reams of bugs, unused code, copy pasta, and so on. When you are tasked to make enhancements to this code, it seems like anything you do will likely cause it to break. In this session we will take a codebase of questionable quality and walk through a series of refactorings. I will lay out a consistent approach that you can apply to such code, and we will cover the common refactorings that are available in Eclipse, Intellij, and Visual Studio. If you bring your laptop along, I will be using Eclipse and code I find on Github, so you should be able to follow the presentation as we go through it.

    3:45 PM - 5:00 PM : Room 115 : Beginner's Guide to Refactoring Code (Level: 100)
    Speaker: Daniel Juliano

  • Building a Distributed Message Log from Scratch

    Apache Kafka has shown that the log is a powerful abstraction for data-intensive applications. It can play a key role in managing data and distributing it across the enterprise efficiently. Vital to any data plane is not just performance, but availability and scalability. In this session, we examine what a distributed log is, how it works, and how it can achieve these goals. Specifically, we'll discuss lessons learned while building NATS Streaming, a reliable messaging layer built on NATS that provides similar semantics. We'll cover core components like leader election, data replication, log persistence, and message delivery. Come learn about distributed systems!

    9:00 AM - 10:15 AM : Room 114 : Building a Distributed Message Log from Scratch (Level: 200)
    Speaker: Tyler Treat

  • Building Large, Yet Maintainable, ASP.NET Applications

    As an application adds more and more features, if you're not careful, it can quickly spiral into becoming the application no one on the team enjoys working on. This talk is structured as a series of lightning talks on various topics to help you improve the maintainability of your ASP.NET applications. We'll discuss libraries and best practices to help with folder structure, validation, ORM's, unit testing, code flow, DevOps, and more. By the end, you should be able to take at least one thing away that you can start implementing immediately when you get back to the office.

    3:45 PM - 5:00 PM : Room 113 : Building Large, Yet Maintainable, ASP.NET Applications (Level: 100)
    Speaker: Scott Sauber

  • Building your own AI (in a tube): DIY Alexa, Cortana, and Google Home

    Amazon Echo devices are affordable and are now in every home. Every windows machine comes with Cortana and Cortana even lives in entertainment systems. Would you like to build your own Cortana, Alexa, or Google home from scratch? We have built a device for under $100.00. We will show you how to design a 3D printable case. We will discuss our hardware selection for the brain of our very own Ai. We will show what we used for microphone and audio. Finally, we will show the code under the covers on selecting the Ai of choice and bringing the tube to life.

    Speaker: Jason Logan and Benjamin Beeksma

  • Data Visualization with ggplot2

    This session will introduce you to data visualization using ggplot2, an elegant and versatile plotting system for R. ggplot2 is based on a "grammar of graphics" for describing and building plots. Data is mapped to aesthetic attributes (color, shape, size, etc) of geometric objects (points, lines, bars, etc). Statistical transformations may be applied and the plot can be drawn on a specific coordinate system. A plot can be repeated for subsets of the data using facetting. Sophisticated graphics can be built up in layers, combining multiple data sets if desired. Themes can be used to control things like font size and background color. Much of the power of ggplot2 comes from the fact that it is based on coherent set of principles. Although this means there is a bit of a learning curve, ggplot2 is not going to get you 90% of the way to your desired graphic and leave you frustrated that there is no way to achieve what you really want. Basic knowledge of R will be assumed but not absolutely required. You'll come away with a basic understanding of how to create data visualizations using ggplot2.

    3:45 PM - 5:00 PM : Room 108 : Data Visualization with ggplot2 (Level: 200)
    Speaker: David W. Body

  • Debate Me

    For about 15 years I have been developing software and in that time have settled on certain opinions and preferences based on my experiences. Confirmation bias and the bubble that I am in reinforce those opinions and preferences. In this talk audience participation is required. I will be presenting a list of my personal opinions and preferences and, for each one, will open up the floor for friendly debate. My hope is that I can learn something and at the same time impart some useful information to all who attend.

    2:15 PM - 3:30 PM : Room 109 : Debate Me (Level: 100)
    Speaker: Matthew Morrison

  • Demoing Everything

    Demos are a hugely valuable tool so that the team and the people around the team can see progress. Traditionally, more technical demos such as back-end services or support issues, either are not done or are so hard to follow they shouldn't be done. This presentation is filled with advice and tactics so that you can successfully demo 'everyone' and give your audience the knowledge they need to know what is actually going on.

    3:45 PM - 5:00 PM : Room 109 : Demoing Everything (Level: 200)
    Speaker: Joshua Carson

  • Docker is Helping NFM Better Serve our Customers

    I am planning on presenting the several flavors of Docker we are using at NFM including: 1. Developers running Docker for Windows on VMware virtual machines running Windows Server 2016 highlighting how we use Docker Compose to support local instances of our Microservices during development. 2. Utilizing Docker running on Ubuntu and Centos Linux virtual machine in our CI/CD pipeline to support our integration testing and how this solution is integrated with Microsoft Team Foundation Server 3. Running a private Docker Registry to manage our build Artifacts in or CI/CD pipeline and getting the Registry tied into Microsoft Team Foundation Server Managing our docker containers within our DC/OS clusters which is our chosen  Orchestration solution for our environments I am planning on hitting on some of the technical hurdles we had to overcome to get Docker up and running in each of these scenarios. There were different issues and expertise we had to gain in order to implement each different flavor of Docker. My hope is that by sharing some of the successes and failures we had along the way, others will be able to streamline their efforts of utilizing Docker. If there are are additonal topics of intertest to you, please let me know and I may be able to incorporate them into my presentation

    10:30 AM - 11:45 AM : Room 114 : Docker is Helping NFM Better Serve our Customers (Level: 200)
    Speaker: Michael Nichols

  • Fast UX and Usability Testing for Agile Teams

    One of the benefits of agile development practices is responding quickly to feedback. We tend to focus on how to develop software in a way that gives us those capabilities, but it's time to start talking about how to actually get a useful feedback loop tied into the process. This will be a highly pragmatic discussion with real examples and demonstrations of how to create scripts, find participants, conduct measurable research and present findings.

    3:45 PM - 5:00 PM : Room 107 : Fast UX and Usability Testing for Agile Teams (Level: 200)
    Speaker: Matthew Nuzum

  • Form Inputs: The UX Issue You Didn't Know You Had

    The lowly form input: it's been a part of HTML for as long as HTML has had a formal specification, but before HTML5, developers were hamstrung by its limited types and attributes. As the use of smartphones and their onscreen keyboards has flourished, however, inputs have taken on a new and incredibly important role - but they're also riddled with browser and device inconsistencies. Learn how input types and patterns can give your users a better onscreen keyboard experience, and how to abuse these features to meet the needs of today (if you must).

    2:15 PM - 3:30 PM : Room 113 : Form Inputs: The UX Issue You Didn't Know You Had (Level: 100)
    Speaker: Aaron Ladage

  • He's Assertive, She's Aggressive: Recognizing patterns of unconscious bias in the workplace

    People tend to classify one another by gender, race, or other physical characteristics and instinctively react based on stereotypes and cultural norms. These automatic prejudices (often called unconscious bias) contribute to the disproportionate success of white men in STEM when compared to equally qualified women or minorities. The key difference between unconscious bias and intentional discrimination is that the individuals that participate in it are often motivated to end these behaviors when they're brought to their attention. This discussion will cover common patterns of unconscious bias that occur in the workplace and offer concrete actions to intervene as an employee, a manager, or an organization.

    3:45 PM - 5:00 PM : Room 112 : He's Assertive, She's Aggressive: Recognizing patterns of unconscious bias in the workplace (Level: 100)
    Speaker: Andrea Mascher

  • High Performance Websites Revisited

    10 Years ago Steve Souders of Yahoo published the book High Performance Websites that described in depth how browser engines request assets and render html, and how to tune your pages for speed. Around the time the book was released, Yahoo also released YSlow, a tool which leveraged the highlights from the book to give a web page a grade for rendering speed and to help with tuning. Do the principles from 2007 still apply today? For this session a younger, hipper colleague of mine (Ben Kallaus, another developer at Telligen) will debate me as we cover the tuning recommendations made by the book and discuss whether they are still relevant. We will also spend part of this session reviewing developer tools built into Chrome and will describe how we use them as part of everyday development.

    9:00 AM - 10:15 AM : Room 113 : High Performance Websites Revisited (Level: 100)
    Speaker: Daniel Juliano

  • Introduction to AWS Step Functions

    Speaker: Eric Larssen

  • Introduction to Blockchain

    If you want to know what Blockchain is, how it relates to crypto-currencies like Bitcoin and why people compare it to early days of the Internet then this session is for you. I will give an overview and practical ways to get started based on my own experience and share other resources if you want to dive deeper.

    2:15 PM - 3:30 PM : Room 114 : Introduction to Blockchain (Level: 100)
    Speaker: Eugen Burianov

  • Introduction to the R Language and Ecosystem

    This session will introduce you to R, a popular language and software environment for data analysis and visualization. We will cover some of the basics of the R language, but we will focus on examples of the kinds of things that R excels at, like data manipulation, statistical computing, and data visualization. We'll also introduce the R ecosystem, including R packages and RStudio. We'll see examples of how you can easily create documents containing code and graphics using tools like R Markdown, or create and publish interactive data-driven web applications using Shiny. No prior knowledge of R is required. The emphasis will be on breadth rather than depth. You'll come away with a basic understanding of what R is all about and suggestions for how to learn more.

  • Kotlin: The New Standard for Android

    Earlier this year, Google announced that Jetbrain's Kotlin (https://kotlinlang.org/) programming language was becoming a first class citizen for Android development. Being a much more modern programming language, Kotlin support marks a turning point for Android development, similar to the introduction of Swift for iOS development. This talk will cover the basics of the language and what makes it unique from Java, then I will get into setting up and using Kotlin in your Android projects as well as converting existing code to the new language. This is an introductory talk on both the basics of Kotlin, as well as Android development and setting up an app.

  • So you want (someone else) to learn to code

    My first programming classes in college were so bad that I withdrew from school and worked for a couple of years before regaining a love for programming. Since then I've had a number of opportunities to mentor youth wanting to learn programming, teach a class for homeschoolers, give presentations at high schools, and mentor new hires fairly fresh to professional programming. Two years ago I made a radical shift in my professional career and once again had the opportunity to be reminded of what is is like to go back to the beginning and learn afresh. Discussion items: - Inspiring love of programming - Experiences of what has worked and not - Tools, learning materials, teaching - Mentoring others

  • The Signposts on Your Agile Journey

    When I first saw the infamous Deloitte Agile Landscape diagram, I wondered how did agile get so complicated. The second thought was a question: 'how can I inspect those techniques and practices and choose the right ones for my team?'. In this session, I’ll talk about how empirical data (which I’m calling agile numbers) can serve as signposts on our journey to reach the goal of delivering customer value faster with maximum reliability and minimum issues. I’ll show how agile numbers can help us determine if a practice is worth the investment and whether it will improve our team’s performance. I will also share examples of agile numbers that can assist you in your agile journey. Those numbers are pulled from different sources like scientific studies, research from Google, and the 2017 State of DevOps Report.

  • The Trials And Tribulations Of Being A Fully Remote Developer

    Imagine working from home full-time. Your job choices are not limited geographically. You have a nice quiet workspace in your comfortable home with limited distractions. Lunch break in your easy chair. What's a dress code? You don't have to go outside in the morning during a frigid Iowa winter. Sounds perfect. Now imagine this actually happening to you and nothing goes to plan. How do you stay motivated? How do you deal with communication breakdowns? The feelings of isolation? Of feeling like a second rate employee of the company? In this presentation, Mike will review the tips and techniques he has learned over the past several years while being a full-time remote developer. This session is geared both towards developers and managers of remote development teams.

  • When is the feature done done?

    How does a development team ensure that the feature they are working is done? Development teams throughout time have tackled this task. Organizational dynamics makes this task different per team. Some common techniques emerge though to ensure that a feature gets done as quickly and accurately as possible. I will be facilitating an open discussion on how the above question is answered while also giving insights from my time on development teams. Topics discussed will include Git, CICD, Client Interaction, etc... Be prepared to participate.

  • WPF (and WinForms) isn't dead (Workshop)

    Let's look at two workplace scenarios. You have created amazing business applications (or) you start a new line of business application by creating a new project in Visual Studio. 90% of the time, it will default to WinForms or WPF. Why move your line of business apps and re-write them as universal apps? This is not necessary. We will show you how to bring your app to Windows App Store and add all the new bells and whistles. We will teach your app new tricks. Your app is not dead. You do not need to move over from your old code. Bring your existing apps that you want to see in the App Store and we will roll up our sleeves and have your app shine as new Universal Apps by using the Desktop Bridge. Takeaways: 1. Ability to add UWP features to existing WPF or WinForms applications 2. Understanding Windows Store Deployment process 3. Window Store Listing
