Going Interactive with the Reactive Extensions
Lately in my series on the Reactive Extensions, you’ll have noticed I focused quite a bit on the IObservable<T> and IObserver interfaces as well as the extensions methods that are included. There is one thing, however, that might have been missed with the release of the Reactive Extensions is the inclusion of System.Interactive.dll. The idea behind this is to include many of the extension methods that are available to IObservable<T> and port them to work on the IEnumerable<T> interface.

Introduction to the Reactive Framework Part V
In the previous post of the Introduction to the Reactive Framework series, we covered how to create new IObservable<T> instances, either from scratch or from existing sequences. What this allowed us to do was turn an operation which was previously interactive, such as iterating over a collection, to a reactive, where I could have multiple listeners reacting to the same collection concurrently. This has nice implications for allowing us to scale our application in interesting ways. This time, let’s take another angle on making asynchronous programming easier.

Reactive Extensions for .NET (Rx) released on DevLabs
As you may have noticed, I’ve been blogging a bit about the Reactive Framework, now the Reactive Extensions for .NET (Rx) and how it will change the way we approach asynchronous and event-based programming. Just as LINQ to Objects changed the way we deal with collections, The Reactive Extensions will change the way we deal with asynchronous and event-based programming. Fast forward to today, Rx has been released on Microsoft DevLabs for not only .NET 4 Beta 2, but also .NET 3.5 SP1 and Silverlight 3 as well.

Introduction to the Reactive Framework Part IV
In the previous post in this series, we covered how to turn .NET events into first class values through IObservable instances. By doing so, we were able to do much more interesting things than just subscribe and unsubscribe, instead we were able to create a mouse drag event with little effort through composition. In this post, let’s look at going from push to pull by turning collections into IObservable<T> instances.

Introduction to the Reactive Framework Part III
In my previous post in the Introduction to the Reactive Framework series, I discussed the duality between the IEnumerable/IEnumerator and IObservable/IObserver and how that enables us to generalize the ideas from LINQ to Objects to LINQ to Observables/Events. After the last post, I was asked how we go from events to Observables, so let’s tackle that in this post.

[ANN] DC ALT.NET – 11/24/2009 “Stop Talking, Start Teaching” with Jeff Casimir
As a group, we’ve been focusing a lot on technology on such things as JavaScript, MongoDB and so on. This month, I’d like to take a step back as a group and instead focus on some soft skills. When I started this group back in 2007, I had the idea that this group would help others not only become better technologists in a wide array of technologies, but also better teachers as well. On November 24th, we have Jeff Casimir to help us understand how to become a better teacher with his presentation “Stop Talking, Start Teaching: 5 Rules for Successful Presentations and Demos”. Listed below are the details:

Introduction to the Reactive Framework Part II
In my previous post, I talked a little bit about the parts of the Reactive Framework that are coming to the .NET 4 BCL as well as their implementation in F# as part of F# First Class Events. This time, let’s come back to the Reactive Framework itself from which the IObservable<T> and IObserver<T> originated. As you may remember, you can play with the bits of the Reactive Framework from the Silverlight 3 Toolkit.
