Continuous delivery

Getting software released to users is often a painful, risky, and time-consuming process. This tutorial sets out the principles and technical practices that enable rapid, incremental delivery of high quality, valuable new functionality to users. Through automation of the build, deployment, and testing process, and improved collaboration between developers, testers and operations, delivery teams can get changes released in a matter of hours–sometimes even minutes.

Rediscovering Modularity with Restructure101

The principles of modularity are applied routinely in the development of classes, but not to the organization of the classes themselves. This is unscalable; inevitably it will extract a big tax on development dollars as the team starts to drown in an ever-expanding sea of classes. This tutorial gives concrete strategies for constructing a hierarchical, levelized, modular structure for an existing code-base, with minimal impact on working code. Many pattern-action-result examples are given.

Hypermedia and ASP.NET Web API, where do you want to go today?

Building hypermedia systems these days is all the rage. Those who achieve building hypermedia systems are promised fame, success and mountains of riches. OK that’s not true! But hypermedia does help you to build systems where the client and server can evolve somewhat independently, and that is a big deal. Come this talk and we’ll deep dive into exactly what hypermedia is and different ways to achieve building hypermedia driven systems with ASP.NET Web API.

Software in the Age of Sampling

Software was once built by skilled but peculiar artisans, who meticulously crafted their original, green-fields commissions from first principles. Today, existing resources are rehashed, recombined, and remixed to produce “new” mash-ups based up the work of others.

This session will explore how software developers in the age of sampling have as much in common with contemporary high-tech music “producers” as they do with traditional engineers.

Maven vs Gradle, On your marks, get set, go!

Ant, Maven, Gradle, Buildr - the choice of built systems for Java based systems is manifold and only discussions about coding styles are getting more heated than discussion on which built system is superior. In this talk we are looking at two built system - the well established veteran Maven against the Groovy based newcomer Gradle. Where are the similarities between these two built systems and what differentiates them? Why and when would you chose one over the other?

Less - The Path to Better Design

The concrete principles of Object Oriented Design are useful but are built upon powerful concepts that the principles tend to obscure. When design principles become goals in and of themselves, object oriented design gets a bad name and applications suffer.

This talk strips away the well-known design principles and exposes the hidden, underlying goals of design. It reveals programming techniques that allow you to write less code while creating beautiful, flexible applications.

Designing Hypermedia APIs

Ruby on Rails did a lot to bring REST to developers, but its conception leaves the REST devotee feeling a bit empty. "Where's the hypermedia?" she says. "REST isn't RPC," he may cry. In this talk, Steve will explain how to design your APIs so that they truly embrace the web and HTTP. Pros and cons of this approach will be discussed, as well as why many aren't building things this way yet.

Why Mud Still Rules

The cause of programmatic pulchritude has been championed by many, from the Literate Programming boomlet of the seventies, the Architecture craze of the eighties, the Patterns Movement of the nineties, and even the burgeoning Software Crafts movement of the current decade, alas, to little apparent effect. Because, for all our aspirations to the contrary, the de-facto standard software architecture remains the ubiquitous and enduring “Big Ball of Mud”.

What are the mudslingers doing right?

Retrofitting a software architecture to an existing code-base

We can do without architecture early on, but at some point a clearly communicated architecture offers big productivity benefits to developers who otherwise drown in the expanding implementation-level detail. When you realize you are heading for a Big Ball of Mud, you have 3 choices – start over, suffer on, or knock your codebase into shape. This talk outlines principles, options and examples using Structure101 to get the best return for the cost and intellectual effort invested in a codebase.

Async in C# 5.0 - No More Callbacks!

For modern connected apps, asynchronous programming is necessary to ensure responsiveness of devices and scalability of services. However, asynchronous programming tends to be a teeth-grinding quagmire of dynamically wired-up callbacks, busting any attempt at well-structured code and practically ensuring bugs and poor error handling. C# 5.0 changes all that. The new 'async' language feature along with futures/promises-based APIs bring back the good old imperative experience. Come see how!

API Usability: Think of the humans!

APIs are consumed by programs, but those programs are built by humans. A good API is one that both programs and humans enjoy using. That means the API not only has to be powerful and responsive, but usable, too. Using examples like Twilio, Twitter, and FourSquare, we'll discuss what makes an API usable or not. We'll talk about common usability traps and the bugs we make or prevent consuming applications. Finally, we'll discuss approaches to API development that improve usability.
