When you want to display your launch screen longer as normal you can do this by simply adding a sleep() in the AppDelegate implementation: 
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Time in seconds
    sleep(5);
    
    // Override point for customization after application launch.
    return YES;
}

Xcode quit unexpectedly.

Click Reopen to open the application again. Click Report to see more detailed information and send a report to Apple.

While in the process of implementing a JSONP proxy writter the following message will pop up when running the code:
Error: [ERROR][Ext.data.proxy.Server#create] JsonP proxies can only be used to read data.
There is nothing in the Sencha Touch documentation, that tells me that a proxy writer can not be used.

After looking at the framework code it was clear to me, that the source code had not been implemented.

With that, you really do need a JSONP writer, otherwise you have to implement the logic yourself or switch back to an AJAX proxy.

There is nothing in the release notes to Sencha Touch 2.2.0 beta 1 that leads me to believe, that any updates on the subject are forthcoming.

Maybe you received  the following error while building a Sencha Architect application:

Error: The package command has moved to 'sencha app package'

This error is thrown because Sencha Architect 2.1 only works with Sencha Cmd 3.0.0 version.

To fix this you have to download and refer one of the following Sencha Cmd 3.0.0 versions:

http://cdn.sencha.com/senchacmd/SenchaCmd-3.0.0.250-linux-x64.run.zip
http://cdn.sencha.com/senchacmd/SenchaCmd-3.0.0.250-linux.run.zip

If you bought a German version of Photoshop CS6, you may want to switch back to English. In this post I will show you a trick to do this without taking use of a language pack.

The main problem is, that Adobe disallows us to switch the language in Photoshop directly, as you can see at the following screen:


Ok, here comes the trick (I am quite sure this will work on other language versions too).
  1. Make sure that Photoshop is closed!
  2. Open the Finder: /Applications/Adobe Photoshop CS6/Locales/de_DE/Support Files
  3. In the "Supported Files" directory you will find a file named "tw10428.dat"
  4. Rename "tw10428.dat" to "tw10428.bak"*
  5. Start Photoshop (GUI language should be English now)
  6. Done! :)

* To rename "tw10428.dat" > Right click on "tw10428.dat" file > Select "Get Info" > Goto the "Name & Extension" label > In the textfield you type "tw10428.bak".

After closing the current dialog don't forget to confirm the changes with "Use .bak".

There are many ways to clear the localStorage of your web browser.

In a common dev toolbar just type: 
localStorage.clear();
If you are using jQuery: 
$.storage('clear');
If you are using Sencha: 
// proxy
var store = Ext.getStore('YourStore');
store.getProxy().clear();
store.data.clear();
store.sync();

// no proxy
var store = Ext.getStore('YourStore');
store.removeAll();
store.sync();
You can also delete the localStorage via a bookmark. Just add the following snippet as new bookmark: 
javascript:(function(){localStorage.clear()})();
