Don Box and DSLsDon Box wowed a large crowd with his funny yet insightful presentation style. In the world of programming interfaces, strong typing can help in this regard. Forcing Functions - the best usability guides are devices that keep users from making simple mistakes by prescribing a logical sequence and enforcing it. In the end it is the same old "hammer and nail" effect but the object success may have caused a significant amount of inertia that makes for a bigger hammer. What Color Are My Shoes? Don Box and DSLsDon Box wowed a large crowd with his funny yet insightful presentation style. An interesting theme during the panel focused on how much a methodology and notation can help developers come up with good designs. How else would you declare a typed variable of a type that is anonymous? Web Services Contract FirstChristian Weyer is working on a quite interesting tool called WSCF - Web Services Contract First. Also, aren't coding instructions just data for the execution engine? Libraries and tools also serve an important community function by widening the reach of a specific technology. I feel that these kind of goals are too often stated somewhere in a project charter but too rarely make it into actual designs. Service-oriented architectures have rather simple composition rules but pay close attention to loosely coupled interaction between systems. This is the approach of the evangelists and, to some extend, the patterns authors. A key aspect of composability is that something must perform the composition. Note that this solution requires nUnit 2. ConclusionAbstractions are a good thing, but let's not get carried away thinking that calling the abstraction "configuration" is suddenly going to eliminate the need for developers. Asynchronous Service HandlerOn the provider side things naturally look a bit more synchronous: you need to accept a request and process it. Particularly, because all the assumptions that you became used to making are no longer given. Code DownloadThe complete solution does not contain a lot of code but still a little more that I showed here. Enhanced network libraries allow you go get a lot more information about the status of the network connection. The channel behavior and the events are the key coupling point between components. The basic MEP of request-reply has made this distinction so confusing. Some programming languages allow for a more flexible model, where the caller can choose where something should go after it completes a function. However, if you are developing a code library or a published service, your users might be far away or might want to access functions even after the original developer might have left the company. We got to see Harry Pierson, Brenton Webster, Arvindra Sehmi, Beat Schwegler, Simon Guest and a few other usual suspects on stage. In the Java world they are a pure language features, i. This started to get us thinking that what we created was not a simple configuration file but really a high-level programming model for the composition layer of our system. However, some open source alternatives seem to be appearing. When I tell a coworker that I use "Asynchronous Callback" for my Web service he or she might think that I use an asynchronous client API. " - Yumai Chang"You want to have fun, you come to my room. Also, since many of these languages are based on standards or are embedded in commercial tools they have to be fairly general purpose to maximize their applicability. Generics allow types to be used as parameters to define methods and classes. What if I want to change the SoapAction name at deployment time? One is the DebugChannel.
