Here is an updated list of presentations for 2023.
| Title | Abstract | Presenter |
| Everything But Occurrences: How and Why the DQMH Framework Utilizes (Almost) Every Single Synchronization API in LabVIEW | DQMH is the world’s most popular 3rd-party framework for LabVIEW. One of its many benefits is the accessibility it provides to CLAD and CLD-level LabVIEW developers. And the framework is so accessible because most of the nuts and bolts of its operation are never even seen by module developers. In this presentation we will pull back the curtain on how DQMH works under the hood, and in doing so, illustrate the ways in which events, queues, notifiers, semaphores, and yes, even rendezvous, facilitate all of the complex synchronization mechanisms that DQMH developers and users don’t even need to think about. | Darren Nattinger and Fabiola De la Cueva |
| Terrible API Design | Are you interested in annoying the people who will have to maintain your code after you get fired? This is the presentation for you. Learn how to avoid all the tricks that make code easy to use and understand. Using OO? You’ll learn a few anti-patterns that you should definitely start using all. the. time. | Brian Powell |
| GIE Summer of LabVIEW Square Battle Finals | We at the G Idea Exchange Committee are hosting a Square Battle competition this summer and are hoping to have the final battles live on stage at GDevCon N.A. We would give a brief overview of what the committee has been doing, where we’re going, what the Square Battle is and how we wanted to use it promote open source contributions. Then show the final battles giving commentary around them. | Eric Schlieper and Casey May |
| Driven Development | Software development processes govern all our lives. We all abide by some life cycle model, implicitly or explicitly. More than that, most probably we’re adopting multiple paradigms while working on our projects: We’re practice test-driven design when we think about testability, or we leverage behaviour-driven development to improve collaboration between project stake-holders. Sometimes, all at the same time. There is a plethora of methodologies, and each one has its time and place, as they cater to specific aspects and facets of our projects. Just think about how different phases in our project call for different paradigms, and how we shift our focus from debugability (DDD) while commissioning a project to supportability (SDD) when we’re maintaining a project after acceptance and delivery to the customer. This presentation gives an overview of available development paradigms, and draws a picture of how they are interconnected, how they augment each other, and how they can be mapped to different situations. The audience will participate in discussions. Beginners will take away a basic understanding of development models, and when to focus on which model depending on their situation. Advanced users get a chance to discuss and compare notes with peers and improve their way of working. | Steve Watts and Joerg Hampel |
| A HAL of a Good Time | Reduce cost and enable engineering efficiency with a properly architected Hardware Abstraction Layer (HAL). A HAL supports parallel development, combats obsolescence, and increases reuse code. HAL creation should begin with a well architected design. Common design problems often arise during a HALs lifecycle. How do you handle it when your hardware goes obsolete? How do you handle it when different models have different features? How do you manage connections to devices? How should logging, debugging, and error handling be implemented? In this presentation we’ll offer solutions to these questions that can help combat those common problems and make your HAL, and test system, successful. | Quentin Alldredge and Kevin Shirey |
| Introducing New Options for Motion Control Using LabVIEW | After delivering over 50 axes of motion using LabVIEW since 1994, several years ago NI informed me that they would no longer support motion. Partnering with Trio Motion Technology providing motion controllers, I was able to develop new methods to deliver motion systems for my customers. In my presentation I will demonstrate using real hardware multiple methods to develop multi-axis stepper and servo systems using LabVIEW. I will also introduce the Trio Motion Toolkit that I developed that has been reviewed, certified and released by the NI Tools Network. It is the intent of this presentation to make LabVIEW users, both beginners and seasoned professionals, comfortable delivering motion systems, even if they never developed one previously. | Eric Schaffer |
| The LabVIEW Experiment Panel | Here’s your chance to ask the expert. We’ll put together a panel of experts on a topic TBD based on poll of the attendees . Sam Taggart host of the LabVIEW Experiment will be emcee. He’ll introduce the panelists, ask a few questions to set the stage and then open it up for audience questions. It will be recorded and put out as an episode of the LabVIEW Experiment. | Sam Taggart |
| Standing on the shoulders of giants: Learning from Open Source | Using open-source packages and tools is common in LabVIEW development. The presentation will encourage developers to explore the actual source code of the open-source resources they use or discover. It is a great way to learn techniques, style, and best practices. I will show examples of open-source tools and resources used in some of our projects, and I will demonstrate ways that exploring the code itself revealed new ways of solving problems to the team. As a bonus, by encouraging developers to examine the open-source code repositories, we hope to promote more contribution to those projects. The intermediate user might appreciate learning about some open-source projects, and the advanced user should notice how things like Test-Driven Development (TDD), unit tests, scripting, and calling other programming language libraries appear in the open-source world. | Dan Press |
| A Class Act: Apply a Few Simple Design Patterns to Improve Your Code Quality | We’ve had access to object-oriented programming in LabVIEW since 2006, but not every application needs a fully realized object-oriented solution. For those that don’t, the judicious use of a few simple OO design patterns can simplify our work, improve modularity and testability, and deliver cleaner, more easily understood code, all while preserving the look and feel of “traditional” LabVIEW. We will draw on real-world solutions to explore the Template Method, the Factory, the Aggregator, and the State Pattern, and learn how those patterns evolve from and interact with traditional LabVIEW applications. | Allen C Smith |
| Class-ical Composition in G | Should your graph view inherit from a subpanel class or a window class? What about your force sensor state machine? You built inheritance for real sensors and simulated ones, but now you’re also being asked to offer different data reporting options. What if you want to mix and match, or alter all these behaviors on-the-fly? In this presentation, we’ll explore how composition can elegantly solve these thorny problems, and get a preview of how the moZart tool could make composing in LabVIEW easier than ever. | Mike Le |
| Fun With Maker MCUs and LabVIEW | Hobby or maker micro-controllers exist within a broad and interesting landscape. This presentation will explore some of the possible ways to leverage these possibilities for use with LabVIEW. Some pros and cons of doing so will be discussed as well as several methods for accomplishing fun and possibly useful projects. | Matthew Harrison |
| What would a G compiler in G look like? | Come learn about software compiler technologies and how they relate to LabVIEW graphical dataflow (G) programs. | Jim Kring |
| How LabVIEW Community Rocks: An Open Source Journey | Have you ever wondered how open source projects can help you learn and improve your LabVIEW skills? In this talk, I will share my experience of developing Panther Dashboard, a development tool for DQMH Projects. I will show you how I used various LabVIEW community resources, such as blogs, videos, forums and other open source projects, to get inspiration, guidance and feedback. I will also explain how sharing your ideas and code with the LabVIEW community can benefit you and others. You can get valuable input from other LabVIEW experts, discover new ways of solving problems, and create something that meets the needs of your end users. You can also contribute to the growth and development of the LabVIEW ecosystem by giving back to the community. | Enrique Noe Arias |
| Dot Your I’s and Cross Your T’s in Your User Interface | What items should be done to create a highly polished User Interface? In this presentation, I won’t be talking about color schemes or animations (like I usually do). Instead I cover all of the small nuances in LabVIEW to ensure your UI/UX is rock solid. I’ll elaborate on four simple rules to help create professional UIs. These rules are: 1) Prevent Instead of Warn, 2) Filter Features, 3) Simplify Navigation, and 4) KISS for UI. You’ll walk away from this presentation with a better knowledge of UIs to help make your applications safer, more intuitive, and more reliable. | Quentin Alldredge |
