Bing has built a scalable, distributed, and reliable functional reactive computing platform to efficiently evaluate standing queries over the world's information streams in near-realtime. It is one of the major components of the Bing Information Platform that powers Cortana. There is also a smaller…

Rx 2.0 is RTW! Get it here. I caught up with Bart at his whiteboard (of course) to discuss the significance of this release as well address some of the great additions to Rx as outlined below (many of the topics below have been discussed in depth in other Rx interviews with Bart.) We also talk about…

Rx v2.0 Beta is here! Who better to tell us all about it - and in great detail at the whiteboard - than Bart J. F. De Smet. This is a long interview, so take your time. Watch it in parts or at one sitting. There was no easy way to dice this up into separate videos, so we give it to you as it…

The JavaScript implementation of Reactive Extensions (Rx), RxJS, continues to evolve under the direction of Matthew Podwysocki. RxJS provides Rx operators in JavaScript and it does this in a download size of less than 7KB (using GZip compression). RxJS provides easy-to-use…

Interactive Extensions (Ix) introduces a set of additional LINQ to Objects query operators based on the work done in the Reactive Extensions (Rx). I recently visited the great Bart De Smet to learn more about Ix. As usual, Bart clearly explains what Ix is and why they've built this…
