Technical Debt: The Silent Killer
Technical debt is no different from any other debt or liability a company holds. If left alone for enough time, it will slow down development to a crawl and halt the company's innovation in its tracks. Therefore, it must be paid off over time to prevent a technological apocalypse.
This talk will showcase a few different strategies to pay off technical debt. Each strategy takes a balanced approach that does not encourage rewriting applications plagued by technical debt. Rewriting may be the most effective way of reducing technical debt, but it is impractical for most software companies. Features still need to be delivered while paying off technical debt. No matter the development process used by your company, you can incorporate these strategies into your workflow.
Reasons for Accumulation
Technical debt accumulates due to various factors beyond control of a company's developers. These problems must be addressed in the strategy for combating it. Developers must communicate the importance of implementing solutions to these problems to other departments at the company. Other departments may not understand why paying off technical debt is so important, but they can understand the consequences if the debt accumulates for too long.
Problems leading to technical debt accumulation:
+ Lack of development resources
+ Not enough executive buy-in
+ Features taking precedence over platform stability
+ Ignoring metrics that point to legacy code problems
* The "Just one more thing, first" attitude
Complex problems often require complex solutions. Developing a sound strategy for paying off the company's technical debt should be at the forefront of every developer's mind. Every viable strategy will require time to implement and will not instantly solve the technical debt problem. These strategies must be incorporated into the development process and adhered to so that the technical debt may be paid over time. For most software companies, this will be a long road, but persistence and vigilance always pay the best dividends.
This talk will equip every attendee with strategies to tackle their company's technical debt issues and improve their development processes.

Many companies begin their journey into DevOps by using open-source tools to stand up simple but effective continuous integration (CI) and continuous delivery (CD) pipelines for one or two small, leading-edge teams—as a proof-of-concept. These early successes are often followed by an overwhelming demand for more—more teams, more functionality, more traceability, and faster turnaround. DevOps teams may soon find that their initial effort, as effective as it was, does not scale consistently or quickly. After all it was only a proof of concept. This inability to scale slows the momentum created by the early successes. Dan Petit shares his experience with this exact situation, describing how creating a reusable pipeline-as-code script library allows development teams to manage their own pipelines in a self-service approach while simultaneously preserving quality and auditability. He describes the characteristics of the pipeline-as-code model, including its major components and control mechanisms. Finally, Dan explores techniques for capturing, visualizing, and learning from available telemetry, to help drive best-practices and ensure pipelines have consistent quality across all teams.Dan Petit
Elyxor has worked through some real-life IoT projects to transform business processes in the Industrial IoT (often called M2M) space. As the industry matures, it is becoming more clear that well designed business and technology IoT architectures can result in (1) elimination of process waste resulting in saved time and cost, (2) improved data insights to your business, (3) changing experiences for individuals interacting with a business process, and (4) changing how we communicate with customers.
These results sound great, but along this journey and various engagements, we have learned some principles that are needed to make such a project or transformation successful. The discussion is to share these concepts so that your future projects contemplate these items and take the best first step toward a successful IoT solution construction effort.
In our presentation, we will support this discussion with some real-life stories and experiences to provide context. In our role of IoT system integrators and business consultants, we have been able to solve problems in various industries and with different tech stacks.
There are vulnerabilities everywhere. Additionally, there are malicious people who can and will take advantage of these vulnerabilities. As developers, it is our responsibility to protect ourselves from these attackers.
Because it is near impossible to write secure code 100% of the time we must rely on features that will help recognize when our code is being attacked, and help prevent it in the future. One way we can do this is by implementing a Web Application Firewall (WAF). A WAF will protect web and cloud applications by providing a set of rules that will cover some of the most common attacks such as cross-site scripting (XSS) and SQL injection. Both XSS and SQL Injection rank first and third in the Open Web Application Security Project's (OWASP) list of top ten most critical web application security risks.Corrie Moore
SOLID principles make software more flexible and maintainable.
In this talk, I touch on each of the principles:
Single responsibility principle
Liskov substitution principle
Interface segregation principle
Dependency inversion principle
However, rather than talk about them in the abstract, the talk focuses on a specific code example. The example starts out as a Slack integration that shows a random "Magic the Gathering" card in a channel when a certain command is issued. I refactor the code to integrate with Twilio and demonstrate each principle along the way.
The example is written as a Spring Boot application and all source is available on Github.
React pioneered the component based frontend and revolutionized how we think about building a web application. Let’s leverage the patterns we learned from React with the latest web primitives and see if we can #UseThePlatform to build a better web.
We’ll discuss how to simplify your application while we compare React to Web Components with Google Polymer. As mobile becomes the dominant experience, we'll see why now more than ever initialization time & overall performance matters. Lastly, you’ll get to hear how Comcast is building its next generation single page apps for millions of customers using the latest browser APIs, Redux and Web Components with Google Polymer. You’ll walk away from this talk feeling motivated and empowered to simplify your architecture.
Microsoft’s move to make .NET open source could not have come at a better time. As the world explores and moves to Microservices Architecture (MSA) and Linux containers, .NET stands poised to not only join the fray, but to excel with high-performance services.
In this fast-paced session, you will see .NET code (C# and F#) be turned into microservices, running in Red Hat’s OpenShift PaaS. Linux, .NET, docker, kubernetes and MSA will all be tied together in this peek into the future. To finish up, we’ll demonstrate two deployment methods: Blue/Green and Canary, and show how uninterrupted deployments are possible.

The MVP community is comprised of over 4,000 MVPs worldwide, and offers you a rich and diverse network of talented tech experts who can help you learn new skills and advance your career. As an MVP, you also gain insider access to Microsoft product development teams, and a plethora of other benefits. Come join the discussion and learn how to reap the rewards of your best season yet!
I delivered this talk at CodeMash in Sandusky, Ohio, and had a panel of 7 MVPs speak for part of the session to educate attendees on how they can be awarded in the future. Many of the attendees noted on Twitter that this was their favorite session of CodeMash. Attendees have appreciated the transparency and awareness I bring to the MVP nomination process through this talk. It is also a great way for attendees to meet Microsoft MVPs and make connections with other community leaders since much of the talk is driven by questions from the audience. This talk is ideally suited to community leaders and those active in the community (speakers, bloggers, etc), but is also suitable for attendees who are new to the community and looking to build connections to widen their impact.
I keep things fun by bringing candy or a small giveaway to encourage participation and to keep people bright eyed in the event that the talk is scheduled after lunch.
Often the phrase "Rapid Application Development" means writing code that is mostly meant to be thrown away, but does it have to? With Acceptance Testing and the right tooling, you can be confident that your productive and rapid application development workflow will live on and not break for years to come (yes YEARS).
In this talk, we'll look at live coding a CRUD interface for a T-Shirt store fully test driven.We'll be using Ember, Ember CLI, Bulma, and QUnit as a base to confidently make the application.At the end, we will have a tested application with Continuous Integration on TravisCI and auto deployed to Surge.sh.
The idea for this talk started several years back, when I first began full-time with Symas. I was working on a project that spanned multiple companies with my friend and colleague, John Field, who's a security architect at EMC, now Pivotal.
At the time, we were working on a process to migrate legacy COBOL apps from running on their native IBM z/Series mainframe platform to run on top of open systems architectures, i.e. Linux.
These were massive programs with millions of lines of code, built over decades. Their conversion processes required mimicking the mainframe's legendary security controls onto Linux platforms, using what was available to us via native and non-native security controls.
This meant dealing with a multitude of security concerns across every tier of the system and into many of its sub-layers as well. Mandatory access controls were enforced on every node in the system.
Linux systems had to be hardened to the nth degree and at the same time, multiple grains of authorization were required within the platform layers. Fortunately, everything we needed to do all this was already readily available and usable, and easily found within the public domain.
Only open, established, and timeworn practices were being targeted. That is, technologies released under permissible licenses, like the Apache software license, and these things were allowed into the final design. Our problem wasn't with how to design the security system, per se, nor how to build it. Strangely, those were the easy parts.
The hard part for us was how do we convey the contents of its complex design to others in a way that is understandable? Because, many of us are not, shall we say, security afflicted, so despite recommending only best practices, their concepts remain arcane, complicated, and generally not known to the masses.
To break through this complexity barrier, John and I borrowed an idea remembered from our youth, and that is those science textbooks that depict the human anatomy. You remember the ones that use translucent pages, each with a particular organ, all overlaying together comprising the comprehensive image of the human body, complete with all of its sub-systems?
We thought this a good way to communicate our complicated security system design to others. We adapted this idea for our end-to-end security design layout. Each image corresponds with an individual security component contained within a typical web app from it's outer to innermost layers.
What's unique about this particular talk is that it started with those initial visual images of a typical web security system architecture.
Next, a test application was created to go along with those anatomy images. The test app mimicked a typical web system, complete with test pages, links, buttons, database tables, et cetera, all of which are under tight security controls of various types.
The goal of the test app was to create a comprehensive tutorial demonstrating all of the pertinent security controls that were contained within the anatomy diagram. Finally, we added instructions to install, deploy, and run the test app and published it all to GitHub.
The project is called The Apache Fortress Demo, and we used it in our live demos and it could also be used by anyone else who wants to try it out at home. During our live demos, we would simultaneously dissect and discuss the web system security functionality, switching between the Power Point slides visually depicting the images and into the concrete demo to show how it all worked in a live system.

With the updates to iOS and Android phones released earlier this year, Web Components are now supported natively. With libraries such as Polymer that are built on top of Web Components, it is now possible to easily create fast Progressive Web Apps (PWAs) without the overhead of a framework. In this workshop, we'll begin with a brief introduction to Web Components and Polymer, and then dive into hands-on experiences with the core aspects of Web Components: the <template> tag, Custom Elements, and the Shadow DOM.
By now, you've probably heard about how awesome Azure Functions really are. From offloading functionality to automating processing, they allow you to harness the cloud to your bidding, whether it’s the dirty work of processing your data or informing your henchmen about your next plot to take over the world. Whether your preference is C#, JS, Python, or a slew of other languages, you can program just about anything with Azure Functions and execute it with triggers, timers, or HTTP requests. In this session, Kentico Technical Evangelist and Azure super-fan Bryan Soltis will show you add Azure Functions to your arsenal and build amazing cloud solutions.Bryan Soltis
This talk provides an overview of a supervised classification problem applied to talk classification in a business context.

Some of the most interesting stories come from the career paths of software testers. What did you do before you started testing? Everyone has a before. Everyone has a moment they can point to when they realized quality assurance was something they might enjoy, and that it was an actual job. Then, came test automation.
Automation divided the discipline into distinct groups: pro-manual, pro-automation, and bored.
Uncover how exploratory testing can re-ignite a discipline and pave the way for more to enter testing as a career path.
The clock is ticking! With just 30 minutes of troubleshooting, how close can you get to finding the root cause of a Java performance problem in production? What observability tools would you use? What subsystems would you investigate?
This presentations shows one approach to getting the most out of your 30 minutes and aims to show that much more is possible than is generally thought, even for Java developers with little exposure to performance tuning.
You will learn to identify the most widespread, repeated and pernicious Java performance defects using walk-throughs of more than a dozen server-side performance puzzles that are ready to run on your own machine.
As an antidote to pervasive and lackluster average response times that are multi-second throughout the industry, this presentation provides a long absent, easy-to-follow performance training regimen that we all should master early on in our careers.
This presentation is your guided tour to how much is really possible in 30 minutes.

Learn how to add notifications, remote and local, to your application. Whether it’s an iOS, Android, or Windows, it’s easy to add notifications. We will take a look at using AWS Notification Service, Azure Notification Hub, and even doing your own Push Notifications with PushSharp.
Push notifications are a mainstay for making a polished and well-rounded application. It's important on how you handle your notifications and display them. The wrong sound or not navigating to the item can make for a poor user experience.
In this talk we will take a simple ASP.NET MVC application and check it in to VisualStudio.com Source Control. We will then use the online Build tools to automate builds on check-in. Then using the online release management we will automate deploying it to our Dev, QA and Production environments. All the while ensuring that we keep all of the configuration for each of these environments safe.Shawn Weisfeld
Everyone knows that when you assemble a bunch of underdogs together, they become an unstoppable force. Whether it's Voltron battling a Robeast, or a bunch of ants taking on a biker flying biker gang, combining several resources into one is a great way to add strength and capabilities to a team. In this session, Kentico Technical Evangelist Bryan Soltis will show you how to apply these same principles to building web applications using microservices for content hosting and delivery, search, and automation, all hosted in Azure.Bryan Soltis
Working in a continuous testing environment requires us to think on multiple levels about how we test our code.
We have our core component library which we can sandbox and experiment with in React Storybook. We can test our components thoroughly here in *multiple browsers* to check compatibility and function.
Then we assemble our components in a react app, where we implement another level of unit and functional testing.
Our react app has very specific goals, which we can acceptance test through WebdriverIO (Selenium). All of this can run in the background *and* on a continuous integration server as part of our build process so we can continually iterate on our code without fear of introducing breaking changes.
This tight feedback loop is key for pursuing continuous deployment and rapid delivery of code and allows us to go further with greater confidence than before.
In this talk, we will walk through some tooling and explore examples of how you can implement continuous testing in your delivery lifecycle using thing like React, Redux, Storybook, Mocha, Jest, WebdriverIO, Selenium, and GO CI.
Drupal has been one of the leading technologies in the enterprise CMS space for many years. A large share of the organizations using Drupal according to the 2017 Drupal Business Survey include Government & Public Administration and Healthcare & Medicine, Charities and Non-Profit industries. Additionally, huge brands like NBC, Turner, The Weather Channel, WWE also leverage Drupal today. We will look through case studies across some of these verticals to see if Drupal could be the right fit for your organization.
In our session we are going to dive into the features of Drupal to show the power and flexibility behind how it manages content models. We’ll talk through the history in how we transitioned over the years from thinking in terms of content living on “web page” to now managing content across many channels (Twitter/Mobile/Chatbot/Alexa/etc.). I’ll make the case for why Drupal is uniquely positioned to serve content to create today’s “Omnichannel” experiences.
Finally, we will look at technologies like REST, JSON API, GraphQL which expose content to other frameworks and systems. We’ll look at distributions like Acquia Reservoir and Contenta which make it easier for developers new to Drupal to onramp to this platform. Whether you are working at a Government agency, University, digital agency, or other industry I want you to come away with an understanding for how Drupal can serve as your organization’s “Content Hub.”

- How can I make sure I'll wake up and get to work in the morning?
- What do I do about house distractions (pets, kids, lawn or cleaning services)?
- What do I do when my internet goes down?
Lastly, once you are working remotely, it's helpful to have some methods for battling the loneliness of working on your own day to day. You'll walk away armed with many ideas to help keep your day your own without being "on your own."
Most agile practitioners first learn agile by reading a book, attending a class, or attending local meetings. But learning lean and agile concepts works best when we're able to put some concrete examples and practice behind the concept. By adding a set of games and exercises that teach and reinforce lean and agile concepts to our toolboxes, change agents can provide some practical basis for conversations both inside and outside their organization. Being able to talk beyond anecdote and theory and actually demonstrate why something works the way we think it does is a powerful statement.
The games in this session will cover a variety of lean and agile concepts, including:
- Preferring small batch sizes and maximizing customer value
- Identifying bottlenecks and the differences between local and system-wide optimizations
- Encouraging experimentation and risk-taking
- Demonstrating the need for good communication
- Backlog prioritization and delivering on commitments
Following the workshop, attendees will have access to all of the workshop games and be able to run these exercises and games with their teams, managers, and executives.
A look at where computing and analytics began and where it is headed.
The basis of all DevOps and development starts with our measurements. We need to understand what role analytics and metrics plays in modern computing. To find out, we look at where analytics began in the advent of computer science and where we stand today, with an eye toward the future.
Unfortunately data can lie, and it’s not even intentional. Everyone from business owners to consumers want insights from the software they use daily. But how can we make sure that the data is being visualized accurately and effectively? Learn how to craft honest and insightful dashboards by avoiding common pitfalls inherent with data visualization. This design centric presentation goes through the entire process of dashboard design including: data visualization, creating a color palette, accessibility, and working with data.Jeremy Jones
In this talk, the creator of Laravel we'll take you on a tour through Laravel and how it can be used to build modern, robust, and testable web applications.

The Microsoft Bot Framework is not just about Skype. You can build bots for Skype, Facebook, Slack, SMS and much more. You can leverage your existing C# skills and create interactive bots that can assist users.
In this session you will see a bot created in real time, as well as learn about the considerations for building a useful and successful bot.
Automation is often misunderstood, and means a lot of different things to a lot of different people. I want to help change that. By drawing on my years of experience building and managing automation teams within a variety of environment, I will walk you through the things you should or shouldn't do. I'll help you understand what things need to be considered, and what things you should simply pass on. I'm not going to teach you how to automate, but I AM gonna to teach you how to succeed at it.Jon Robinson
# Being Lazy in the Cloud - Finding Efficiencies in AWS to Make Life Easier
AWS out of the box tends makes things more difficult than they need to be. I'll show you some easy ways to simplify your interactions with the AWS cloud that will free up time and make your life easier. Some of my tips may even save you some money!
My name is Nick Volgas and I'm a software developer turned sys-admin wannabe. I started using AWS for both work and personal projects in 2015 and have spent a large amount of my time automating and tooling myself out of having to work in any way possible. I've gotten both an AWS Solutions Architect Associate certification as well as an AWS DevOps Professional certification. I'm currently the Director of IT Operation at the Information Network of Arkansas and this is my second year presenting at LR Tech Fest.
AWS provides a wide array of tools and methodologies for hosting your infrastructure in the cloud. Out of the box, however, I've found myself wishing things that should be simple would be just that...simple! I'll walk you through some of the inefficiencies encountered by the normal user and how to overcome those. I'll show you some examples of AWS-provided time savers as well as some home-grown processes. I'll provide any code I demo on my github account for use after my talk and will provide links to write-ups on how to perform each task I demo. Did I mention I will demo each of these LIVE?
Here are some examples of things I'll explain that will make your life easier:
- Account switching made easy
- Auto-deletion of old backups
- Consolidate billing across accounts
