Introducing ASP.NET vNext - A tour of the new ASP.NET platformJeffrey T. Fritz
Jeff Fritz shares how to get started with the new ASP.NET framework. He covers the goals and intents of Microsoft, and shows how you can get involved with this exciting open-source project. By the end of the presentation, you'll understand and be comfortable with the changes coming in the next version of ASP.NET
Microservices with Java, Spring Boot and Spring CloudEberhard Wolff
Spring Boot makes creating small Java application easy - and also facilitates operations and deployment. But for Microservices need more: Because Microservices are a distributed systems issues like Service Discovery or Load Balancing must be solved. Spring Cloud adds those capabilities to Spring Boot using e.g. the Netflix stack. This talks covers Spring Boot and Spring Cloud and shows how these technologies can be used to create a complete Microservices environment.
Once you have your Microservices setup, the most pertinent question is how to I test Microservices and ensure that all the moving parts of this distributed system stay in sync.
The presentation provides testing strategies on how to test Microservices and provides focussed understanding of using Consumer Driven Contracts (CDC) to test Microservices API. Additionally it provides pointers around how to do debug Microservices and trace the performance of individual services.

The next version of ASP.NET is more than just a minor upgrade. The surface may seem familiar, but the underlying framework represents nothing less than a paradigm shift. Rewritten from scratch to support modern tooling and guidelines, ASP.NET MVC 6 can run just about everywhere and has a ton of features designed to support SPAs, including Angular apps.
This presentation, which was given at the AngularJS-IL Meetup, introduces ASP.NET 5 and MVC 6 and focuses on features that benefit Angular apps.

Let’s face it, when was the last time you opened a command prompt as part of your daily routine? Did you know you can save a lot of time by creating scripts that automate your daily tasks, such as altering your application’s configuration files and then deploy the application to a remote server? There are developers that still think that scripting is the IT department’s domain. But Windows PowerShell is a different story. PowerShell is a scripting language that is more coding than scripting, mostly because its commands return objects, not text.
In this session we will learn what PowerShell is, the basics of coding with it, and how to call it from your .NET code. Most of the session will focus on how developers can benefit from using PowerShell in their day-to-day routine in order to work with XML and JSON, automate deployments, manage certificates, call HTTP services, manipulate file content, and more. Next time you are asked to deploy your application to the server, type, don’t click!

In The Trenches With Tomster, Upgrading Ember.js & Ember DataStacy London
A few months after I started working with Ember.js & Ember Data at my new job we began a project to upgrade both. There were parts that were a breeze and others that were quite tricky. This talk walks you through some of the challenges we faced and how we solved them as well as how we began to prepare for the Ember 2.x architectural shift. Hopefully this talk will help save you some time when you decide to upgrade your Ember web application.
Web API or WCF - An Architectural ComparisonAdnan Masood
ASP.NET Web API is a framework that makes it easy to build HTTP services that reach a broad range of clients, including browsers and mobile devices. The new ASP.NET Web API is a continuation of the previous WCF Web API projection. WCF was originally created to enable SOAP-based services and other related bindings. However, for simpler RESTful or RPCish services (think clients like jQuery) ASP.NET Web API is a good choice.
In this meeting we discussed what do you need to understand as an architect to implement your service oriented architecture using WCF or ASP.NET web API. With code samples, we will elaborate on WCF Web API’s transition to ASP.NET Web API and respective constructs such as Service vs. Web API controller, Operation vs. Action, URI templates vs ASP.NET Routing, Message handlers, Formatters and Operation handlers vs Filters, model binders. WebApi offers support for modern HTTP programming model with full support for ASP.NET Routing, content negotiation and custom formatters, model binding and validation, filters, query composition, is easy to unit test and offers improved Inversion of Control (IoC) via DependencyResolver.
You will walk away with a sample set of services that run on Silverlight, Windows Forms, WPF, Windows Phone and ASP.NET.

APIs are one of the main elements of cloud services. All major cloud service providers expose REST APIs to allow you to programmatically access their services and capabilities. SOAP and REST are the two most common ways of exposing APIs, whether to external, partner, cloud, or internal developers.
The concept of API management is to publish these web APIs for consumption, and includes capabilities such as monitoring, security, and documentation.
This presentation introduces basic concepts of APIs, API management, cloud REST services, and a brief walkthrough of WSO2 API Manager and the Oracle API Gateway to see how you can centrally publish, expose, and secure APIs, essentially virtualizing your backend services.

Getting started with dotnet core Web APIsKnoldus Inc.
Web API is a framework for building HTTP services that can be accessed from any client including browsers and mobile devices. It is an ideal platform for building RESTful applications on the .NET Framework12. You can learn how to build secure and scalable REST APIs with ASP.NET Core, the same framework and patterns you use to build web pages and services
Spring is widely used for creating scalable applications. For web applications Spring provides
Spring MVC which is a widely used module of spring that is used to create scalable web applications. But the main disadvantage of spring projects is that configuration is really time-consuming and can be a bit overwhelming for the new developers. Making the application production-ready takes some time if you are new to the spring.
This talk introduces the role that Spring MVC and REST can play as a service-side endpoint model that can be connected to from mobile, rich, and desktop applications.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

3. OWIN & KATANA
Open web Interface for .Net
Spec is here
Katana: A Microsoft implementation of OWIN
Not a replacement for ASP.Net / SignalR or WebAPI.
Just offers hosting methods.
Reduced interaction between the server and the
applications
Application delegate:
Func<IDictionary<string, object>, Task>
4. INSPIRATION
RACK
Rack provides a minimal, modular and adaptable
interface for developing web applications in Ruby. By
wrapping HTTP requests and responses in the simplest
way possible, it unifies and distills the API for web
servers, web frameworks, and software in between (the
so-called middleware) into a single method call
Node.js
Node.js is a platform built on Chrome's JavaScript
runtime for easily building fast, scalable network
applications. Node.js uses an event-driven, non-
blocking I/O model that makes it lightweight and
efficient, perfect for data-intensive real-time applications
that run across distributed devices.
5. INTRODUCTION
Minimal, modular and adaptable interface for
developing web applications
Exposes a wrapper for Http requests and http
responses
Single method call to handle
Web Servers
Middleware
Web Applications
6. OWIN
To decouple server and the web applications
Defines the structure and requirements of HTTP
request and response interactions
Support for applications in any platform
Example
Kayak => runs on nix systems using Mono
7. ARCHITECTURE
Application: Because Katana is not a replacement for
ASP.NET but rather a new way to compose and host
components, existing ASP.NET Web API and SignalR
applications remain unchanged, as those frameworks can
participate in an OWIN pipeline. In fact, for these kinds of
applications, Katana components will be visible only in a small
configuration class.
Middleware: The name given to all of the components that
handle requests in an OWIN pipeline. It can range from a
simple compression component to a complete framework such
as ASP.NET Web API, though from the server’s perspective, it’s
simply a component that exposes the application delegate.
Server: Responsible for binding to a TCP port, constructing the
environment dictionary and processing requests through an
OWIN pipeline.
Host: The process that runs the application. Can IIS or
standalone executable. The host is responsible for startup,
loading of other OWIN components and shutting down
gracefully.
9. APPLICATION START-UP
IDictionary<string, object> creation and populates any
startup data or capabilities provided by the host.
Server selection [owinhost or iis]
Location of the application setup code and invokes it
with the Properties collection.
Reads and/or sets configuration in the Properties
collection, constructs the desired request processing
pipeline, and returns the resulting application delegate.
Invokes the server startup code with the given
application delegate and the Properties dictionary.
The server finishes configuring itself, starts accepting
requests, and invokes the application delegate to
process those requests.
13. WHY HAVE PIPELINES [SOC]
Authentication: Plug-in various authentication
mechanisms. How do I validate this OAuth, HTTP
Basic Authentication, name/password?
Authorisation: "is the user authorized to perform
this particular task?", i.e. role-based security.
Caching: have I processed this request already,
can I return a cached result?
Performance & Usage Monitoring: what stats can
I get from the request and response?
Execution: actually handle the request and provide
a response.
17. OWIN MIDDLEWARE
Grouping and ordering of the modules
Are run for each request
Similar to that of a HttpMessageHandler
[subscribes to each request]
Sample Middlewares
Static file renderers
WebAPI
Nancy [web framework for mono]
18. ENVIRONMENT
All states, including
application state,
request state,
server state etc,
are held in the IDictionary<string, object> object
specified on the application delegate.
This is passed from component to component as a
request progresses through the pipeline
No specific .NET object model, such as those of
HttpContextBase in ASP.NET MVC or
HttpRequestMessage/HttpResponseMessage in
ASP.NET Web API
