Forward Leaning Software Engineer
Brian Sletten is a liberal arts-educated software engineer with a focus on forward-leaning technologies. His experience has spanned many industries including retail, banking, online games, defense, finance, hospitality and health care. He has a B.S. in Computer Science from the College of William and Mary and lives in Auburn, CA. He focuses on web architecture, resource-oriented computing, social networking, the Semantic Web, data science, 3D graphics, visualization, scalable systems, security consulting and other technologies of the late 20th and early 21st Centuries. He is also a rabid reader, devoted foodie and has excellent taste in music. If pressed, he might tell you about his International Pop Recording career.
Imagine the simplicity of REST married to the power of Unix pipes with the benefits of a loosely-coupled, logically-layered architecture. If that is hard to imagine, it may because the architectures available to you today are convoluted accretions of mismatched technologies, languages, abstractions and data models.
NetKernel is a disruptive technology that changes the game. It has been quietly gaining mind share in the past several years; people who are exposed to it don't want to go back to the tired and blue conventions of J2EE and .NET. Not only does it make building the kinds of systems you are building today easier, it does it more efficiently, with less code and a far more scalable runway to allow you to take advantage of the emerging multi-core, multi-CPU hardware that is coming our way.
Come see how this open source / commercial product can change the way you think about building software.
NetKernel makes the things you are doing now easier, but also makes new types of systems possible.
A wise man once said, "XML is like lye. It is very useful, but humans shouldn't touch it." If you've had to incorporate XML into your project by hand, you have probably been burned by getting too close. NetKernel turns this wisdom on its head and encourages you to use XML like the liquid data stream you want it to be.
But, XML is only part of the story. Resource-oriented computing is a generalized and revolutionary approach to modern, flexible systems. There is less code to write, but it is more fun to do. Orchestration of existing services and data sources is faster, easier and more encompassing than with more conventional technologies.
This talk will help explain what NetKernel is (app server? pipeline tool? embedded SOA?) and, through a comprehensive set of examples, give you a glimpse at a deeper software reality than you might have thought possible.
Disclaimer: There will be no blue pills given to you to make you forget what you have seen. Come with an open mind.
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.
The human-friendly Web is about nicely-formatted, accessible content for users to browse. There is an emerging Data Web that relies on technologies from the Semantic Web stack to link increasingly rich connections between various data sources. SPARQL and RDF are the main tools for expressing and using this connectivity. This talk will introduce you to one of the practical and accessible aspects of employing these ideas on the Web and in the Enterprise.
Getting people to come to consensus on common models and schemas is usually the hardest part of any data integration strategies. These technologies help lower the bar on both the technical and social costs of stepping up your integration strategies.
We will explore:
- an introduction to RDF and the SPARQL query language
- the fantastically successful Linked Data project that connections billions of interrelated content
- how to include relational data in the mix
- how to include enriched Web pages in the mix
- how to build client-friendly applications on top of this information
The goal for web services was always to reduce our burden by increasing the potential for reuse of business functionality. Somehow, we got lost along the way in a morass of confusing, unfulfilling and downright broken technologies.
While we are interested in pursuing REST-based systems for managing information, we need some strategies for tying it all together sensibly. If we abandon WSDL, SOAP and UDDI, what do we replace them with? This talk will walk you through combining resource-oriented strategies with technologies from the Semantic Web to describe, find, and bind to services in dynamic, flexible and extensible ways.
We will start to blur the distinction between data, documents, services and focus on information and how it is connected to what we already know.
This talk will introduce you to strategies for building on individual REST services to produce a well-described, dynamic, discoverable fabric of services that can be used in a variety of scenarios including:
- finding data sources
- finding transformation services
- orchestrating these sources and services in reusable ways
- publishing discoverable services
