I hear a few developers getting down on Xamarin because they are required to:

I'll be at a Meetup in Atlanta on December 11, 2013.  I'll be talking about:

I recently did an online webinar regarding the new iOS7 and Xamarin.  In it, I covered the basics of what is new in iOS7 along with what is new in Xamarin's developer platform.  Please take some time and view this webinar.  The items that were covered include:

No matter your feelings toward Apple, there's no denying the marketplace likes the iPhone and iPad family of products. You can't ignore them, and because you're reading this column, I thought it would be interesting to look at the options you have for creating a UI with Xamarin.iOS. There are two options I'll look at in-depth:

In a previous article, I looked at the HTML5 <video> tag and History object, two of the many features that developers have started to implement to give users of their apps new input controls, jQuery Mobile features, location and mapping, and much more. In this article, I continue exploring HTML5 features with a look at Web Workers, which let you speed up your client-side applications, and Indexed DB, a client-side data storage mechanism that is the preferred storage approach going forward in HTML5. (Before Indexed DB—also known as the Indexed Database API—work was focused on a standard named WebSQL. That work was discontinued in the fall of 2010. IndexedDB is the result of follow-on work to create a standard for data storage in Web browsers.)

Images taken with the camera are rather large in the iPhone.  How do you shrink them down?  I need to shrink them because I am going to send them to a web service and I want to spend as little time as possible in the upload process.  While I am not sure that this is the best code, it seems to be working for me.  I want to put this out for sharing and if you have a suggestion on how to make it better, please let me know.

Who hasn’t started looking at the mobile Web and HTML5—features like the viewport, new HTML5 controls, geolocation and many others that are part of smartphones, tablets and advanced browsers? With these features, developers have started to provide users with fairly common, new input controls; jQuery Mobile features; location and mapping; and much more. In this article, I describe two features that you might not be familiar with: the <video> tag and Web history. The <video> tag lets you display video without the need for plug-ins like Flash. Web history allows users to use the Back button to return to the previous page in an AJAX application.
