Advanced NetKernel : Software for the 21st Century

If you have come to the NetKernel overview talk and came away compelled but unsure how to proceed, this talk will jump right in to building real resource-oriented systems with NetKernel. We will move away from the theoretical mind-melting right into the applied mind-melting. It is difficult to make the shift away from an object-oriented model, but this talk will demonstrate several examples of how and why you may want to. It will also include a preview of what is coming in NetKernel 4. This is kind of a REST + Polyglot Programming + SOA + Architecture talk all rolled up into one.

This talk will build out:

• Wrappers around a relational database that can act as RESTful interfaces through HTTP or service higher layers
• Transformational layers that convert the data into different forms
• Orchestration across a variety of data sources
• Integration with a variety of web tier technologies

All along the way, we will make appropriate language choices to solve our problems. One size does not fit all and an environment that embraces this is incredibly important.

WebGL

HTML 5 has introduced us to the Canvas API, 2D graphics and the pleasures of plugin-free video and audio playback. One of the next hurdles we will face is native support for 3D graphics for simulations, visualizations and games.

WebGL is an early look at supporting OpenGL ES 2.0 in the canvas in most modern browsers through JavaScript APIs.

This will be an example-driven workshop that will cover the basics of 3D graphics, OpenGL and where it is going on the Web.

Resource-Oriented Architectures : REST I

The first in a series of talks that are part of an arc covering next-generation information-oriented, flexible, scalable architectures. The ideas presented apply to both external and internal-facing systems.

The REpresentational State Transfer (REST) architectural style has emerged as a winning strategy for building scalable, flexible, resilient systems that lead with an information focus. Far from being the simple "Web Services through URLs" idea many people have about them, REST-based systems require a new perspective, a fair amount of consideration and the discipline to look beyond simple point-to-point interactions.

The benefits are exciting and provide a gateway to a whole new world of information technology. This first talk will be an introductory session covering the basics of the REST architectural style.

Resource-Oriented Architectures : REST II

The second in a series of talks that are part of an arc covering next-generation information-oriented, flexible, scalable architectures. The ideas presented apply to both external and internal-facing systems.

People already familiar with REST (or who have attended the first session) will be walked through the deeper topics of building Level 3 Hypermedia-based RESTful systems, security, content negotiation, etc.

Resource-Oriented Architectures : RDF/SPARQL

The fourth of a series of talks that are part of an arc covering next-generation information-oriented, flexible, scalable architectures. The ideas presented apply to both external and internal-facing systems.

The Web of Documents we are so familiar with is being extended with the technologies of the Semantic Web. Information will be freed from its containers and connected regardless of where it comes from. Building on the concepts of REST services and the Web Architecture, we will introduce the Resource Description Framework (RDF) as the basis of a new collection of tools for information sharing and integration. Once the information is woven together, we will want to query it and produce new information resources with technologies like the SPARQL query language.

People already familiar with REST and the Web (or who have attended the REST sessions) will be given both conceptual and technical examples of how and why these technologies are laying the foundation of future information systems.

Resource-Oriented Architectures : RDFa

The fifth in a series of talks that are part of an arc covering next-generation information-oriented, flexible, scalable architectures. The ideas presented apply to both external and internal-facing systems.

Once we have a flexible and extensible data model like RDF, we will want to find ways to weave it into our documents to make them easier to organize, find and extract value from on the Web. This talk will highlight techniques for adopting RDFa but will also motivate attendees to dig deeper by showing them how it is already being used by the biggest names on the Web. Improve your search results and allow your customers to leverage relevant information for their own purposes.

You understand how important it is to be on the Web. Come learn how important it is to be on the Web of Data.

Resource-Oriented Architectures : Semantic SOA

The sixth in a series of talks that are part of an arc covering next-generation information-oriented, flexible, scalable architectures. The ideas presented apply to both external and internal-facing systems.

This talk will wrap up the vision presented in the other sessions into an integrated service oriented architecture that yields results on the promises we were given a decade ago, even if we have to consider alternate technologies to get there.

We will walk through the adoption of new REST services, wrapping legacy systems, describing these services with metadata, documenting them, discovering them and binding to them in run time orchestrations.

Attendees should be familiar with the topics presented in the first four talks before attending this fifth one, although we will try to make it accessible on its face value.

HTML 5 Overview

People are confused about the status of HTML 5. Is it ready? Is it not? What is part of the spec and what isn't? We'll talk about the situation in the "HTML 5 and the Kitchen Sink" discussion, but as always, the proof is in the pudding. We will introduce the most exciting new features of HTML 5 and its related technologies and build examples that use them.

We will work with real code covering:

The new input elements Editable content Canvas Element and its related 2D APIs for drawing and animation Audio and Video elements and how to use fallbacks for codec coverage Browser native drag and drop Local storage Web Workers Websockets The Geolocation API Web DB (SQL in the browser!) This workshop will assume no special knowledge of HTML 5 and should be accessible to any web developers.

Bring your laptops. This is a hands-on workshop.

Semantic Web Workshop

The Web is changing faster than you can imagine and it is going to continue to do so. Webs of Documents are giving way to machine-processable Webs of Information. We no longer care about data containers, we only care about data and how it connects to what we already know.

Perhaps the concepts of the Semantic Web initiative are new to you. Or perhaps you have been hearing for years how great technologies like RDF, SPARQL, SKOS and OWL are and have yet to see anything real come out of it.

Whether you are jazzed or jaded, this workshop will provide you with the understanding of a technological tidal wave that is heading in your direction.

In this workshop, we will:

Explain the Web and Web architecture at a deeper level Apply Web and Semantic Web technologies in the Enterprise and make them work together Integrate structured and unstructured information Create good, long-lived logical names (URIs) for information and services Use the Resource Description Framework (RDF) to integrate documents, services and databases Use popular RDF vocabularies such as Dublin Core, FOAF, DOAP Query RDF and non-RDF datastores with the SPARQL query language Model and Do Inference with the Web Ontology Language (OWL)

Bring your laptops. This is a hands-on workshop.

Visualizing Data on the Web

We are far from the early days of ugly HTML. We have sophisticated visualization tools available to us now to help our users consume complex data in attractive and informative ways.

Come hear how you can adopt these visualization systems (calling them libraries is inappropriate) today.

This talk will introduce:

• D3.js
• RGraph
• SVG in the Browser
• Highcharts
• Raphael
• Reusable widgets from the Simile Project

Resource-Oriented Architectures : Adopting the Semantic Web in the Enterprise

The seventh of a series of talks that are part of an arc covering next-generation information-oriented, flexible, scalable architectures. The ideas presented apply to both external and internal-facing systems.

While there is a lot of interest in using Semantic Technologies in the Enterprise, there is very little guidance on how to go about doing so. It sounds like a scary Big Bang change, but the truth is, there are incremental steps that can be adopted gradually.

This talk will be an introduction of how you can begin to advocate and apply Semantic Web technologies iteratively both internally and on the public Web.

Topics will include:

How to explain Semantic Web technologies to various stakeholders Difficulties/processes faced when adopting new technologies Mapping these technologies into existing industry trends Adopting a Resource-Oriented view of the world Data Integration strategies Using RDFa Building and extending metadata repositories that unify your documents, data and services

Resource-Oriented Architectures : REST III

The third in a series of talks that are part of an arc covering next-generation information-oriented, flexible, scalable architectures. The ideas presented apply to both external and internal-facing systems.

The move to a good REST API yields an explosive combination of options due to content-negotiation and arbitrary workflows. At the same time, the uniform interface you project (representations, how you respond to verbs, response codes, etc.) becomes your contract with your clients. The API itself becomes a completely transportable, reusable bit of organizational knowledge when done well. Testing it sufficiently will give you a safety net but may drive you crazy unless you do it right. We will walk through the use of Behavior-Driven Development (BDD) to test these kinds of APIs.

We will highlight the problems of sufficiently testing REST APIs while providing a rich and relatively straight-forward solution to the problem. We will use a Behavior-Driven Development (BDD) tool like Cucumber to establish reusable steps and comprehensive, but lightweight testing strategies for testing REST APIs.

This talk will not be an introduction to REST. If you have come to the REST I or REST II talk, or have a good understanding, it should be very accessible.
