Welcome at this series of blog posts: How to create a utility app with Sencha Touch and Sencha Cmd. Originally I wrote this tutorial for .NET magazine and afterwards I modified it for the Sencha Blog Site. Since I think it’s a good set of articles and you might have missed it. I will also […]
Last week was a very important week for Sencha. We recently introduced Ext JS 5 to the public. It’s now possible to try out the beta version! As a Sencha employee I already had early access to this framework; that gave me enough time to play around with it. ..and I have to say… I […]

Please note: this bug won’t occur with Sencha Touch 2.3 (and higher) I have to admit, I am in love with the Google Chrome browser. Except yesterday, Google Chrome automatically upgrades itselves to the latest version. This latest version, version 29, suddenly breaks all Sencha Touch 2.2 apps. And ya, you can’t downgrade Google Chrome. […]
