When I first created this site, I used it both as a test bed for technologies as I played with them and as a repository for others to use for my presentations and other insights. Over the years people have been free to grab these samples, but haven’t had good ways of giving back to help improve the samples. In the mean time, there have been quite a number of technology changes. While I may have been late to the party on some, there’s only so many things one can focus on. One of the advances we’
A couple of years ago I gave a presentation at the last MIX for doing asynchronous programming using Reactive Extensions (Rx) on the Windows Phone. The video of the presentation is still available for watching. Around the same time, I was approached by Code Magazine to write a similar article, which I was happy to oblige. It took a while but I was happy to see the article finally published in the Sep/Oct 2013 edition of Code Magazine. In the article I demonstrate how to use Rx to build a dice r
It seems that every customer I talk with these days are chasing the elusive write once run anywhere. Typically, the best answer is to go with HTML5/JavaScript because it is the most ubiquitous option across devices. One recent customer that I was working with has a fleet of Windows Mobile 6.5 devices with native applications that they are looking to upgrade to a more modern hardware device. Unfortunately, the browser on the Windows Mobile 6.5 devices do not support HTML5, or the necessary app pa
For anyone who hasn’t had the opportunity to attend one of my in person presentations, or are frustrated by the audio quality of my MIX recording, join me on Wednesday, May 25 at 11:00 EST when I discuss using the Reactive Extensions on the Windows Phone as part of Telerik’s new Windows Phone 7 Wednesdays video series. Here’s the session details: Becoming an Rx Pusher on your Windows Phone with Jim Wooley on May 25th at 11am EST https://www1.gotomeeting.com/register/419991849 The Reac
When people ask about resources to learn how to use Rx on the Windows Phone, I often point them to the How to guides, including the How to: Use Reactive Extensions to Emulate and Filter Accelerometer Data for Windows Phone. Unfortunately, I have a problem with the underlying implementation of the emulation method which returns values through an iterator (yield) and IEnumerable<T> and then cast the IEnumerable to IObservable. As I pointed out in a MSDN forum post, It would be better to reco
I’m happy to have been selected to speak at MIX this year. This is an exciting conference combining developers and designers and focusing on increasing application User Experiences. The focus of my talk will be to show some practical uses of Rx in the context of the Windows Phone 7. If you’re going to attend MIX, I would love to see you at this session. Otherwise, the sessions are typically recorded. I’ll add a link to the recording once it becomes available. Here’s the session description as it
Part of the power of RX lies in it’s ability to compose complex operations  and keep the resulting code maintainable. I previously showed how to perform Drag-Drop operations with RX. This time, I want to take a look at a slightly more complex operation: Detecting “Shake” gestures on the Windows Phone 7. The phone includes the ability to detect motion in 3D space through the built-in Accelerometer in the Microsoft.Devices.Sensors library. This sensor raises events when the phone is moved w
