New Workshop! Developing Modern User Interfaces Using WinRT

I am offering a new workshop that is dedicated to developing Windows Store Apps using WinRT and related technologies such as HTML, JavaScript, CSS, XAML and C#. The workshop is intended for people who want to find out whether Windows Store Apps are a good option for your application development in addition to or instead of desktop/web application development. It takes 1 or 2 days depending on your needs and offers insights to the exiting world of Windows Store App development.

You can find more details here (German only).

HTML5 with JavaScript and CSS3 Specialist

As part of continuously maintaining my certifications, I passed the exam Programming in HTML5 with JavaScript and CSS3.
Although a lot of developers think that JavaScript is a poor programming language compared to Java or C#, mainly due to it’s weak typing and limited IDE support, it is impressive to see what you can do with it. The main key to understanding is to abandon the notion that JavaScript is an OO language. The name JavaScript is really misleading as it implies that JavaScript is close to Java. But beside the curly braces there is not much common ground.

By passing the exam I achieved the additional certification Programming in HTML5 with JavaScript and CSS3 Specialist

HTML5 Geolocation

Recently I’ve been playing with HTML5 features just to see what it can do in the area of Rich Internet Applications (RIA).

Especially geolocation, local storage and application caching got my attention.
As I don’t think privacy is a concept of the past, I thought it would be a nice use case to track a persons location and store it locally.
So I created a little Location Tracker App to show those features in action.

The required browser features are not supported on all desktop browsers. But due to the fact that most mobile webbrowsers are based on Webkit, it runs on almost any mobile device. (Using a location tracker on a fixed PC seems to be of limited use anyway ;-))

It is amazing to see what you can do with HTML5, Modernizr, KnockoutJS, jQuery and a few lines of JavaScript. For me HTML5 is an interesting option especially for mobile devices.
