Opening Session

As a friend of mine always says, "Technology is easy; people are hard." As important as it is to grow your technical skills, it is vitally important to also nurture your personal skills. In this session we will dive into the "soft" skills that are often harder than the complex technology we work with every day, using scientific studies and actual case stories where knowing the technology wasn't enough, backed by 15 years of experience in consulting, working with dozens of clients and technologies, and hundreds of individuals from developers to C-Suite executives.

In 2024, there are multiple ways that your next big money-making idea can get off the ground. However, choosing the right tools upfront means being able to add features sooner and make your customers even happier. In this interactive session, we'll explore what it takes to build a modern fullstack serverless application on AWS that uses generative AI. We'll then iterate on the the approach by introducing new features and services based on real-world scenarios from actual AWS customers.

You may have heard about this thing called .NET Aspire, and you've been told it's only for cloud native distributed systems and microservices. Did you know that's not the case? .NET Aspire brings value to any application whether it's a single majestic monolith running on-premises or an application with thousands of microservices running in the cloud. In this talk, we'll break down Aspire from the ground up. We won't be creating an Aspire project that pre-wires everything up for you. We'll start with an empty project and then add on the Aspire bits so you can see how this works under the hood. We'll set up the app host, the service defaults, various Aspire components, and of course the fancy dashboard. By the end of this talk, you'll not only have a better understanding of what Aspire is and how it works, but you'll also realize that every application should be using Aspire today, not just cloud native distributed applications.

Do you want to test all of your Entity Framework queries without setting up a test database? Do you want to test your API without leaving Visual Studio? Do you want to add integration tests to your CI build without adding another library? Do you want to "cheat" and hit 95%+ code coverage? In this talk, I will walk through using the WebApplicationFactory (Microsoft.AspNetCore.Mvc.Testing) library to spin up your API in memory. I will then show how to add an in-memory data connection. Finally, I will pull it all together and show a full integration test.

Everyone finds themselves in the position of looking for a job at some point in their career. The key is being ready, which should start before you are looking. This talk will equip you with practical tips from your resume/LinkedIn, what to do along your career to help you tell your story, interviewing pointers, the compensation conversation, and what employers look for when they turn outside to hire leaders and senior engineers. I'll also shoot straight about the strategic use of third-party recruiters - when and, more importantly, when you should NOT use one. You do not need to actively look for a role to find value in this conversation. My goal is to give engineers a streamlined approach so that when the time comes, they are prepared and it's a positive experience.

Developers who love strongly typed languages like C# but also see the value of rich interactive web applications can now "have it all" with Asp.NET Core Blazor! Blazor is a component-based, reactive framework that builds on top of modern .NET, Razor syntax, HTML, and CSS, to create a single-language full-stack application. Components can be statically generated on the server, be live-updated from the server via WebSockets, or run in the client browser just like a JavaScript SPA application. In this session, we will learn how to get started with Blazor, as well as some advanced tips and tricks.

Zero downtime deployments is just something people talk about but never actually do, right? Wrong! In this presentation, Mike will highlight the building blocks to enable zero downtime deployments for an ASP.NET application in Azure.

We will touch on using Bicep for Infrastructure As Code, as well as methods for performing database migrations. After this presentation, you should have all the tools you need to improve your deployment process.

Do you have a lot of BFFs (Back-end for Front-end) that you are maintaining for your front-end applications? Do your front-end applications require a lot of disparate calls to different services? Is your front end having to deal with multiple security models to appease back-end requirements? Are you in the process of modernizing your back-end and need a way to abstract the migration from consumers? This session will include live coding to demonstrate building a federated graphQL schema using disparate technologies and data stores. Furthermore, it will show how a front end can call that graphQL instance using one security model and pull back data from those sources. Finally, we will switch out one of the back-end services and show how the consumer doesn't need to make any changes. Attendees to this session will learn the following items. What is a graphQL query? What is a graphQL mutation? What are subgraphs? What is a supergraph? How do all these items fit together? How does security work? How do consumers interact with graphQL?

Filled with practical examples and real-world user feedback and backed with documentation guidance, attendees will leave the session with a keen understanding of the options available to them and why their team may need to go in a particular direction. Additionally, they will be armed with the proper references to make an educated decision on their project's future direction.

Your team has been working well for a long time, but developers keep checking in the connection strings to Azure Services (like SQL Databases and Storage). You know that once you check in a secret it should be considered compromised so you've built a robust rotation strategy and you are ready to move forward, but you want to solve the real problem, which is preventing the team from checking in (and even knowing) what your secrets are. Another problem that you noticed is that Application Insights and your users are logging sensitive information that needs to be sanitized. In this session you will learn how to get notifications when users have checked in secrets using GitHub and third-party tools. You'll also see how to leverage secrets in your code without having to know the secrets, both locally and at Azure via the Azure Key Vault. You will then learn how to leverage secrets that need to be shared to Azure App Configuration and have the ability to use them from your local and Azure environments. To complete the journey, you will then learn how to capture output before committing to your logs (or app insights) with a few simple code changes to make sure that sensitive information is sanitized before being permanently recorded.

We’re not talking about the outdoor game where you are trying to steal a physical flag and bring it back to your base, this capture the flag is a series of computer security challenges you solve to retrieve a flag and get points! Solving these challenges require various skills including decrypting content, SQL Injection, reverse engineering and more. Learn about how capture the flag works, where you find challenges/competitions, and some techniques required to solve them. I went from never having tried one to winning a competition the next year. The challenges are not only interesting, they helped change my perspective about how web sites are attacked and how I could better protect them.

Question: is it possible to introduce new features and provide bug fixes for an application once the source code is lost? Most of the time, when approached with this scenario, organizations resort to a very expensive rewrite project. What happens though, if the legacy application just needs 10-20 bug fixes and it otherwise sufficient for the time being? Advances in reverse engineering over the last few years have made binary patching and modification much easier than in the past. Even for bytecode-based languages, such as C# (CLR) and Java (JVM), new tools allow for analyzing and even modifying existing programs, without the source code, without even recompiling! Now bugfixes are just an example of the approach, but there is no reason to stop there! Here's a scenario; your business relies on an ancient 3rd party WinForm app for critical business processes; using reverse engineering and binary patching, there is nothing prohibiting you from introducing a REST API on top of the old application, thereby increasing the shelf life of the "legacy" software.

Picasso said, "Learn the rules like a pro, so you can break them like an artist." In this talk, Judah De Paula PhD, will draw upon over two decades of industry experience to discuss some of his favorite rules for writing software and explain why the rules sometimes work better in theory than in practice. For example, one must accept you suck as a programmer before you can be good at it. If you think there is something Zen in that, he does too. Concrete examples will be mixed with theoretical principles to inspire you to think of your daily routine in new ways. Code will be in C# and Python. You might be briefly forced to learn about Pascal the programming language and Pascal the man.

Good feedback has the power to improve performance, increase team engagement, and lead to higher quality products. The ability to deliver feedback is an essential skill for high performing teams. Good feedback is clear and delivered in a way that preserves working relationships. This talk will explore key elements to include in good feedback and leave attendees able to more confidently and effectively communicate both positive and constructive thoughts to their teammates. We’ve all been in a situation where we want to give feedback but are struggling to find the best way to do it. Maybe a coworker said something in a meeting that undermined your credibility or a teammate is consistently delivering late or low quality work. How do you address the situation in a way that preserves your working relationship, but still solves the issue? Giving feedback can feel awkward. What do I say? Am I going to hurt their feelings? We will explore methods for giving well crafted feedback that make sharing your observations with a teammate feel less daunting and lead to more productive team dynamics.

One of the features added in C# 9 is called "source generators", enabling a developer to create new code at compile time. This can be used for a myriad of cases, such as optimization, automating repetitive code, and dynamic API creation. In this session, I'll cover how source generators work and demonstrate a number of implementations.

I would like to cover the importance behind using tools, frameworks, and libraries as black boxes, but making sure that you open the hood and understand what is going on underneath. So often, a lack of deeper understanding about third party code can lead to issues. Performance, security, and just your general approach to development can be improved if you take the time to understand the inner workings of what you are using. Some real world examples will be provided from my experience in the industry and plenty of time for discussion and questions.

One of the best ways to improve data literacy and foster an active, passionate data culture within an organization is to establish a "Community of Practice" around the technologies the organization uses to process, store, analyze, and consume data. In this session, we'll learn about "The Data Dojo: A Power BI Community of Practice," which was established at Des Moines University to facilitate the sharing of knowledge and experience among faculty and staff interested in analyzing the data generated by their teams and departments. We'll also talk about the Data Dojo's egalitarian founding principles and unconventional structure, some of the topics we've covered at our workshops, what has gone right, what we could have done better, and what we're planning for the future. And finally, we'll discuss how you can encourage data literacy and foster a vibrant data culture within your organization by establishing a Data Dojo of your own!

A non programmers show and tell of an engine built for providing novel insight into the action on a basketball floor. Now we really get to see the value of who's out there playing. A college programmer who hasn't programmed in YEARs rolls his sleeves back up on a basketball related passion project. Go get some !

What is a hardware root of trust? Why is it important? What measure of security does a hardened host provide? These are some of the questions I hear when I bring up the topic of boot security. This talk is focused on how computers boot up and how technologies like Intel Secure Boot work. We will go over the boot process before the OS is executed and talk about some of the attacks that are possible at this stage and the impact such an attack can have on the entire platform. After this groundwork is complete, we will talk about how some of the different hardware root of trust technologies work to mitigate the risk posed by these types of attacks.

Working in a product space requires knowing how to take a very complex problem and break it down into iterative chunks. Far too often, we’re so wrapped up in the problems we’re solving professionally, that we completely forget to introspectively look at ourselves and ask what problems in our own lives need solving. Burnout is real and worth addressing. But much like the dev process, understanding the “why” behind behavior leads to a more sustainable outcome. We want to develop a framework and language to properly identify burnout and how we can work through it.

Join us for a wrap up and some door prizes!
