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.
Most people new to Aspect-Oriented Programming (AOP) are fed up with separation of concerns zealots explaining how great their techniques are at dealing with... logging. Ok, you get it. Logging is a cross-cutting concern that can be appropriately modularized. What else does AOP have to offer? A lot, it turns out. This talk will give an introduction to the motivations of AOP as well as a series of concrete examples drawn from enterprise and client side Java. Come learn how AspectJ-flavored AOP can begin to benefit you immediately either in development or production environments. Learn how to enforce architectural policies, find Swing threading issues, reduce the invasiveness of the Observer design pattern or even improve the reusability of your domain models. Now that Spring 2.0 provides support for AspectJ, the time has never been better to learn about these new (but backwards compatible) ways of thinking about building software.
Attendees will learn about
The history and reasons behind AOP
Development-oriented aspects that can be useful, but compiled out of production code
Production-oriented aspects that can simplify development and ease the burden of future changes
Basic AspectJ usage and jargon How to use AspectJ with Spring
Category: Architecture/Languages, Client Side Java, Server Side Java Prerequisites: Basic Java. Some level of AOP understanding is helpful, but not required. The pace of the introduction will depend on the average level of exposure the audience has previously had to AOP.
REST sounds like such a simple thing. But, what is it really? How do you convince your boss to let you try it when she has been sold on the equation SOAP = SOA + P(rofit)? How do you go about building, deploying, publishing and orchestrating web services without the (Un)Holy Trinity of SOAP, WSDL and UDDI?
This talk will thoroughly examine this REST phenomenon in terms of its history, its goals, its consequences and where it fits into the Big Picture of SOA. We will also look at exposing existing tools/APIs through RESTful APIs.
If you find yourself interested in talking about REST without people dismissing it as trivial (yeah, but what is it?!?!), unsaleable (yeah, but I am trying to solve problems, not buy tools!) or not SOA (<insert your own joke here -- that one leaves me speechless>), come on by.
Just as the world is feeling comfortable with the Web, Tim Berners-Lee et al inform us that what we have seen so far is just the beginning. His original plans at CERN were larger and grander. The Semantic Web is the new vision of machine-processable documents and metadata to improve search, knowledge discovery and data integration and management. While there are many naysayers chiding such grand visions, there are also pragmatic and useful technologies emerging that can be applied today.
Attendees will learn:
The history and motivations behind the Semantic Web The technology stack that will make it happen (including RDF and OWL) An overview of tools and technologies that are beginning to satisfy the vision
This talk stands on its own, but feeds into the "Experiencing the Semantic Web" talk which is more hands on.
Prerequisites: This is all so new, most engineers will find something to excite them.
