Topic:
Goodbye client side JavaScript. Hello C#’s Blazor.

Abstract:
For .NET developers, writing client side C# has always been a pipe dream. With the introduction of Blazor this all changes. Blazor is a .NET web framework that runs in any browser. Blazor uses the latest in web standards, WebAssembly. This means no plugins, transpilation, or JavaScript are needed.

In this session we’ll explore what Blazor means for web development and learn about how this experiment at Microsoft is shaping up. Blazor runs in the browser on a real .NET runtime (Mono) implemented in WebAssembly that executes normal .NET assemblies.

Topic:
Understanding Probabilistic Data Structures with 112,092 UFO Sightings

Abstract:
There are three reactions to the title of this talk:

  • What the heck’s a probabilistic data structure?
  • UFO Sightings… wha?
  • 112,092 is an oddly specific number.

This is a talk about the first bullet point with the second thrown in just for fun. I like weird stuff—UFOs, Bigfoot, peanut butter and bologna on toast—maybe you do too? As far as the third bullet point, well, that’s how many sightings I have.

Now, if you’re like most developers, you probably have no idea what probabilistic data structures are. In fact, I did a super-scientific poll on Twitter and found that out of 119 participants, 58% had never heard of them and 22% had heard the term but nothing more. I wonder what percentage of that 22% heard the term for the first time in the poll. We’re a literal-minded lot at times.

Anyhow. That’s 4 out of 5 developers or, as I like to call it, the Trident dentist ratio. (It’s actually a manifestation of the Pareto principle but I’m a 70s kid). That’s a lot of folks that need to be educated. So, let’s do that.

A probabilistic data structure is, well, they’re sort of like the TARDIS—bigger on the inside—and JPEG compression—a bit lossy. And, like both, they are fast, accurate enough, and can take you to interesting places of adventure. That last one might not be something a JPEG does.

More technically speaking, most probabilistic data structures use hashes to give you faster and smaller data structures in exchange for precision. If you’ve got a mountain of data to process, this is super useful. In this talk, we’ll briefly go over some common probabilistic data structures; dive deep into a couple (Bloom Filter, MinHash, and Top-K); and show a running application that makes use of Top-K to analyze the most commonly used words in all 112,092 of my UFO sightings.

When we’re done, you’ll be ready to start using some of these structures in your own applications. And, if you use the UFO data, maybe you’ll discover that the truth really is out there.

Purposeful Personal Branding

Abstract:

Topic:
Real-Time Apps with SignalR

Abstract:
SignalR is cool piece of tech that powers real-time communications and is one the latest additions to the ASP.NET Core family. Yes, SignalR is open source and enables two-way client-server RPC calls – across .NET and JavaScript. This means seamless real-time communications across web, desktop and mobile platforms.

Let’s go under the covers to see how real-time communication works. With rich server-side Hubs, SignalR allows for granular communication and management of .NET, JS & other clients. SignalR easily powers common scenarios of web server backends and cross-platform mobile/desktop/web front ends. And modern SignalR has well thought out features – like streaming, configuration, MessagePack and security considerations. Need scalable hosting or serverless real-time apps – Azure SignalR Service is here to help. Let’s explore SignalR and deep dive into what’s possible with real-time communications!
