Reactive Programming, State Management, and Redux for the Modern Front End Developer

JavaScript

This workshop will give you the basics for understanding GraphQL and then dive deep into advanced concepts like subscriptions. We will do this by building together a little slack clone and exploring how we can solve the problems of such a service by leveraging GraphQL.

You will learn how to build a GraphQL server in .NET as well as how we can consume GraphQL in Blazor WebAssembly applications.

After this workshop, you will know what GraphQL is. You will know how to build GraphQL servers in .NET and various concepts of building a GraphQL schema.


We will explore what GraphQL is and what it is not and how it compares to other service API technologies like REST and gRPC.


What is the query language and how can we apply it?

- Schema Definition Language / Type System


Overview over the GraphQL schema definition language and exploration of the GraphQL type system.


We will look at design principles for GraphQL schemas.


Let’s start applying our GraphQL knowledge! We will take GraphQL for a ride and build
with it step by step a small slack clone that uses a wide range of GraphQL features like subscriptions, filters, persisted queries, and many more things.


We will try out several GraphQL tools and see what we can do with them and our slack endpoint.

- Building a GUI Blazor for our GraphQL Server


We will pick up Blazor and build with it a simple real-time UI that uses our slack endpoint.

When Hollywood uses digital technology to create digital characters that look uncannily like real actors, who gets the royalties? If a programmer creates an algorithm that uses Markov chains to generate song lyrics, who actually wrote the song? In a world where algorithms tell us what to watch, what to read and who to hire, can social networks still claim that they're just platforms - or should they be treated as publishers? Join Dylan Beattie - developer, musician, and creator of the Rockstar programming language - for a fascinating journey along the border between human innovation and digital automation, from mathematics to music and beyond.

Web Components are browser compliant components that can be used in any app that works with HTML.

These components allow us to modularise not just our UI components but also to create highly functional components. These can then be used to convert monolithic apps into a set of independent but connected Micro Apps or Micro Services. We will look at components that have elazy loading, dynamic import and use of IndexedDB for near instant and offline data rendering.

In this talk, we will look at two demos. One will be braking a highly monolithic PHP app into a set of Micro Apps, deployable in an HTML page as well as being able to be deployed into other apps. The other will be a demo of a range of different apps deployed as Web Components, interacting together as part of an enterprise application. A range of Micro App architectures are possible and this one use Event Sourcing and Synchronicity.

Finally, we look at how Web Components can be created by frameworks and deployed in frameworks.

There will be a Github repo containing the first demo project and lessons on Web Components for attendees to follow along with, as well as a YouTube video series for attendees to dive deeper after the talk.

In this session, I'll show you how to write DRY tests by leveraging an open source library called AutoFixture. AutoFixture lets you set up your test scenarios by runtime-generating data that meets your requirements. By not repeating the same boilerplate setup code everywhere, your tests will have minimal coupling to your production code. They will be your safety net while also giving you the freedom to refactor your production code as you see fit.

Don't think that's possible? Join me in this session and see for yourself

Along the way, we'll use partial application, functional dependency injection, validation with Success/Failure results, the Result/Either monad, the State monad, agents with message queues, event sourcing, stream processing, capability-based design, and the interpreter pattern (aka free monad). Phew!

If you're an FP-curious developer, I hope this will be a useful way to get a quick overview of functional programming in practice.

Designing composable functional libraries, not just for data visualization

The terms coupling and cohesion come from the world of structured programming, but they are also thrown about in the context of microservices. In this session, I look at the applicability of these terms to microservice architecture, and also do a deep dive into the different types of coupling to explore how ideas from the 1970s still have a lot of relevance to the types of systems we build today.

I cover a number of topics in the context of microservices, including:

What is the importance of information hiding, and how do you apply it

Different types of coupling, what kinds of problems they can cause, and how you can avoid them

How a surprising amount of good ideas came out of the 1960s and 1970s, but we just forgot them

Hiding The Lead

"Hack Yourself First" is all about building up defensive skills in developers. It looks at security from the attacker's perspective and takes them through the steps necessary to exploit vulnerable software on the web so that they can experience hacking first hand. Workshop participants are set specific goals they must complete that involve probing for risks and then exploiting discrete vulnerabilities in a specially built vulnerable application. The interactive nature of the workshop means that multiple attack vectors are usually identified across the spectrum of participants and each person contributes their own unique perspective as to how specific risks are exploited.

The objective of the workshop is that each person walks away with demonstrated experience across a broad spectrum of specific risks. They not only learn about but also demonstrate practical experience across a range of different vulnerabilities targeted to the specific needs of the group.

Courses run for two days on the following schedule:

The first day build fundamental security skills that all technology professionals delivering applications on the web should posses:

- Discovering Risks via the Browser
- Using an HTTP proxy
- XSS
- SQL Injection
- CSRF
- HTTPS
- Framework Disclosure

The second day delves deeper into online risks, covering more advanced topics in greater depth:

- Password Cracking
- Account Enumeration
- FiddlerScript
- Content Security Policy
- Session Hijacking
- Subresource integrity
- Brute Force Attacks
- Automating Attacks and Review

Attendees will get taught the mechanics of each of these risks and of course the defensive patterns required to defend against them. But more than that, they get exposed to how to think about security; how to apply it in depth via multiple defences, how to choose appropriate controls based on the specific risk of the feature and how to have the discussion about what makes sense in different circumstances.

Above all though, security is just one factor in delivering working software and it has to be applied appropriately. Sometimes it comes with a trade-off against usability or cost and decisions have to be made about not what's just most secure, but what's in the overall best interests of the product being built. This workshop helps those who attend have the right discussions about when and where to invest in security.

- Software Developers
- System Administrators
- Testers

This workshop is aimed at any software developer, system admin or tester who wants to get a better understanding what is going on in cyber space if it comes to hacking and cracking of systems. This workshop enables you to take a pro-active approach and you learn how hackers will try to break your system. This workshop will be an eye opener for most attendees and it is the starting point of becoming a better developer. It all starts with awareness and improving your own habits. So start hacking yourself first, to become a better developer!

Attendees will need to use their own computer with one of following software options installed: Fiddler:

This will be a hands-on workshop designed for beginners in functional programming. We'll do lots of domain modeling exercises starting with some simple models and then enhancing them with constraints, state machines, error handling, commands and events, and so on.

The core concepts of functional programming and how they can be applied to Domain Driven Design

How to represent the nouns and verbs of a domain (e.g. the ubiquitous language) using types.

Why representing the domain model using types is better than UML or other documentation (hint: it can never get out of sync)

How to capture constraints and business rules in the domain model itself instead of being buried in the implementation

How to treat errors as a part of the domain

How to build a complete business workflow from smaller components using composition

How to design a functional architecture with bounded contexts, validation, I/O and on.

At the end of the workshop you'll know how to accurately represent a rich domain using some simple code which can then be used as the starting point for an implementation.

Domain Modeling Made Functional

What if I told you there was a way to migrate one page at a time, keeping everything else running normally? Well, there is. In this talk I’ll show you how to include Microsoft’s reverse proxy in an ASP.NET Core MVC application to proxy requests to your old ASP.NET app, but intercept specific pages and render them using shiny new Razor. With this approach, you can gradually migrate and upgrade your application at the same time as maintaining and supporting it. It may take years, but you’ll get there in the end!

Migrate your Web Apps to ASP.NET Core, one page at a time

ASP.NET Core 5, gRPC, Protobuf, Visual Studio, .NET CLI, Docker, Kubernetes, services meshes, monitoring, distributed tracing

Day 1: Building gRPC applications in ASP.NET Core

Day 2: Security, Deployment and Observability

Service mesh (using Linkerd as an example)

Attendees will be expected to be familiar with .NET and C#, and bring a computer with the latest .NET Core 5 SDK and an IDE (VS2019, VS Code or Rider). For day two a local Docker installation that supports Kubernetes is strongly recommended (e.g. Docker Desktop for Windows or Mac).

Modern distributed systems with gRPC in ASP.NET Core 5

This 2-day workshop will guide you through from beginning with creating containers all the way to running your containers on a Kubernetes cluster in the cloud.

We’ll cover the basics before moving onto more advanced topics, with a combination of slides and hands-on exercises the attendees will learn the fundamentals of containers and by the end of the workshop will have a good understanding of Kubernetes, how to run it and how to run their applications on Kubernetes.

Windows containers (*hands-on exercises will require a Windows laptop)

Windows 10 Pro with Hyper-v and Docker for Windows (with Kubernetes cluster setup)
