Jeffrey rambles about Rx, .NET and programming in general.

As it’s been a long time since I blogged, I figured I owe it to people subscribed to my blog to start a nice long series with regular posts. (Also I can’t stand seeing Matthew have all the fun :)). There have been many samples showing Rx on the client...

Paul blogs about our lack of in depth documentation on some cryptic api names. So here is some description of the names and behavior of Amb, Materialize and Dematerialize. Amb's name comes from a long history, it was named by John McCarthy the inventor...

Today during my presentation at JSConf , I showed that RxJS is not only about the browser. RxJS can be used anywhere JavaScript is available. To showcase that, the webserver I used for my dictionary suggest sample, was entirely written in JavaScript,...

As we just released the Reactive Extensions for Javascript I thought it would be nice to dig a bit deeper in what the sample that ships with the download is all about. For those who haven’t downloaded the bits yet, or haven’t gotten the time to play with...

In part 1 of these series, we talked about how to read a stream asynchronously. This resulted in an operator returning IObservable<byte[]>. This type can be useful in many scenarios, e.g. you’re processing a large image. However there are plenty...

(Reposted due to layout issues) Previously in these series we saw: Reading a stream asynchronously Reading strings asynchronously, line by line Writing an observable to a stream Buffering output to a stream All previous posts dealt with interacting between...

In this Channel9 video , Wes and me explain the new testing functionality that now ships as part of Rx . As the video goes into great detail on why you’d want to test Rx this way, I won’t go into details here. However as the video briefly touches on a...

Previously in these series we saw: Reading a stream asynchronously Reading strings asynchronously, line by line Next, I would like us to take a look at writing an observable to a stream asynchronously. Requirements When we write an observable to a stream...

Previously in these series we saw: Reading a stream asynchronously Reading strings asynchronously, line by line Writing an observable to a stream The last post finished with a warning regarding sending to many small chunks of data to the stream asynchronously...

After working on the Reactive Framework with Erik, Wes and the rest of our team for over a year, it is great to see that the word about System.Reactive is out (as described here , here , here and here ). I thought it might be fun to post a little puzzle...

As kouPhax requested this on the Rx forum , I decided to post a port to Script# of the Time flies like an arrow sample that ships with Rx for JavaScript . Rx for JavaScript already ships with a binding for Script#, so that will make our lives a lot easier...

Here are two solutions I wrote to the puzzle I posted earlier this week. The first version is very imperative and uses the Do operator to side effect, it then uses variables captured in the closure to track its state. This one you have to be careful...

Most of the operators in the set of Observable extension methods are operators that return an IObservable. Some of the operators however return something else, such as First, Last, Contains etc… These operations are blocking operations, they block the...

I accidentally posted my planned post on this subject on the RxTeam blog: http://blogs.msdn.com/rxteam/archive/2009/11/21/observable-context-observable-subscribeon-and-observable-observeon.aspx

Steffen has already posted two beautiful solutions. As often happens with specs, I was not detailed enough about what I want the behavior of the signature I provided to be: I meant multiClickSpeedInMilliSeconds to be the total time between the first...

After 11 years I've decided to leave Microsoft and start on a new endeavor. Because of this, I'll no longer be working on Rx. This will be my last blog post here. Thanks for all the people who've provided feedback! Please pester Erik, Bart and Wes to...

As we released Rx today on DevLabs , I'm finally able to blog a bit more about the Rx technology. I'll kick it off with 3 screencasts on the differences between the 3 different versions of Rx: Rx for .NET 3.5 SP1 Rx for Silverlight 3 Rx for .NET 4 Beta...

Yesterday I talked about Rx specific features when running on Silverlight 3 in part one . Today I'll focus on .NET 4 Beta 2. Watch how Rx uses the new covariance/contravariance feature exposed by C# in .NET 4

Two days ago I kicked of this 3 part series by describing what is unique to Rx on Silverlight 3 . Yesterday followed that up by I talked about Rx specific features when running on .NET 4 Today I'll complete the series by talking about what Rx offers on...

This Saturday I’ll be presenting in Track B at JSConf , talking about Reactive Extensions for JavaScript. I’ll show why RxJS matters, how to use it, show some features of the new release and reveal some slick unexpected uses of the library. So if you...
