Presentation Summary

Once you learn how to blink an LED (the "Hello, World!" of embedded programming), it isn't long before your latest invention needs some sort of wireless access.

In 2014, Ai-Thinker released a small breakout board based on Espressif System's wifi-capable ESP8266 chip. Despite its (initial) lack of documentation, its low price-point quickly caught the attention of the DIY electronics community. ESP8266 has since evolved into a platform with multi-language support and dozens (if not hundreds) of hardware implementations.

This presentation will focus on the more common ESP-01 and ESP-01S versions of the ESP8266-based boards and the Arduino APIs. We will cover two scenarios: 1.) The ESP-01 as part of a larger Arduino project, and 2.) The ESP-01(S) as a programmable board in its own right. In the process, we will go over hardware & software requirements for wifi-enabling your projects, plus code examples for both the add-on and standalone scenarios. And as always, we won't neglect the "gotcha"s.

Speaker Biography

Doreen Clemons is the proverbial chief-cook-and-bottle-washer at Bonaventure Software. She started programming in BASIC on a TRS-80 at the age of 12 and has since earned her living with Visual Basic, "Classic" ASP, ActionScript, HTML, JavaScript, Java, T-SQL, PHP, MySQL, and C#. In her free time, Doreen lives out her Evil Mad Inventor(TM) fantasies by building stuff with Arduino and the Raspberry Pi. During episodes of "coder's block," you can find her being waaaaaay too political on Twitter as @bonaventuresoft.

Presentation Summary

In September 2019, Microsoft announced .NET Core 3.0, an important milestone in the transition from the .NET Framework, a proprietary, closed source, Windows-only platform to an open source, multi-platform framework. It brought with it support for desktop development, C# 8, and enhancements to ASP.NET Core and Entity Framework.

In this talk, we will look at the benefits of .NET Core (focused on ASP.NET Core) for existing .NET Developers as well as the development community as a whole and take a look at the more exciting features of the platform (gRPC support, Blazor, enhancements to Identity, C# 8 features)… using Visual Studio for Mac, deploying to and debugging in a Docker container.

Presentation Summary

In this session, you will learn about WebAssembly: What it is, what problems it solves, how it works, and what makes it secure. Using Emscripten, you will learn how to create a module that can run both inside the browser and outside it, in places like Node.js and VMs like Wasmer.

The session will also include an overview of the Uno Platform where you can develop native mobile, desktop, and web applications using C# and XMAL via a combination of technologies like Xamarin.Forms and WebAssembly.

Speaker Biography

Gerard Gallant is a Senior Software Developer and Architect with Dovico Software. He learned he had a passion for programming in high school. More recently, when he started doing a jog several times a week to relax, Gerard rediscovered a second high school passion -- running. No longer a relaxing jog, his competitiveness has led him to take part in several races a year. As a huge fan of WebAssembly, he was fortunate to have been given the opportunity to write a book on the subject: WebAssembly in Action ( He is passionate about his work, his hobbies and (most of all) his wife and his two young and very clever girls.

Presentation Summary

The software development of the web is being transformed by the introduction of Web Components. Web sites such as YouTube, Facebook, Bloomberg, EA Sports, Dominos Pizza, and many more are using web components to serve billions of consumers worldwide. Originally started as a way to extend HTML with custom tags, the web components spec. has grown to encompass a collection of features that make development of modern software easier to create, manage, and deploy. In this talk we will explore several web component libraries and frameworks such as Polymer 3, lit-html, and lit-element, and also tools for creating Progressive Web Apps. We will also cover scalability techniques for building large scale Single Page Applications and Web Components, plus the need for real-time updates and data streaming.

Presentation Summary

23 years ago, the Java Virtual Machine promised to free programmers from the error-prone drudgery of memory management and the frustrations of maintaining code-bases for multiple operating systems. Alas, the large memory requirements and long start-up times of early JVM versions gave Java the reputation for being "slow." The reputation lingers despite Just-in-Time compilation and two decades of optimisation and performance-tuning. This presentation will focus on some of the most recent changes to the VM to trim down and speed up apps. We will also talk about the high-performance GraalVM that can support multiple languages at once. Depending on time/interest, we might also look at Quarkus.
