[Python] Buffered ouput by default

By default, Python produces buffered output (when you use print).

This could be a problem when you would like to see in "real time" your print(...) for example in a log file.

You can disable the buffer for output, by adding the option "-u" like that :
python -u my_script.py


I had this problem with Tornado + supervisor. I did not understand why my print(..) was not written immediately in my log file => -u option solves my problem !

[AngularJS] [Ionic] ng-click called twice

When I click on a <A> tag having a ng-click, the ng-click is called twice.

For solving this problem, I use the new ng-click provided in the module ngTouch.


The original ng-click provided inside the ng core :
https://docs.angularjs.org/api/ng/directive/ngClick

The new ng-click inside the ngTouch module :
https://docs.angularjs.org/api/ngTouch


For calling the ng-click in ngTouch : 

<script src="angular.js">
<script src="angular-touch.js">

angular.module('app', ['ngTouch']);

[AngularJS] No 'Access-Control-Allow-Origin' header is present on the requested resource

If your Ionic application use $http.post (for calling a restful service for example) and if you try test your application (executed with the command ionic serve) on your PC with a browser like Chrome, you will obtain this kind of message in your JavaScript console :

No 'Access-Control-Allow-Origin' header is present on the requested resource[...]

Solution :

During your test, you can do that :

• replace :

$http.post(url,params);

• by :

var config = {
     method: 'POST',
     data:params,
     headers: {
        'Content-Type': undefined
     },
     url=url
};$http(config);

• and define in your restful application :

"Access-Control-Allow-Origin": "*"

[XDK] rename a project

Let's suppose you would like to rename your XDK project my_old_project to my_new_project


In two steps. But be careful, execute these steps at your own risk !!!!!

First of all, close XDK :)

1- rename your project :

• rename the folder containing your .xdk file : my_old_project -> my_new_project

• rename your file my_old_project.xdk to my_new_project.xdk (same manipulation for the .xdke file)

• edit the files :
• intelxdk.config.android.xml 
• intelxdk.config.crosswalk.xml
• intelxdk.config.ios.xml
• intelxdk.config.windows8.xml 
• and replace <name>my_old_project</name> by <name>my_new_project</name>

• edit my_new_project.xdk and replace "appName_": "my_old_project" by         "appName_": "my_new_project"

2- delete the caches of XDK:

• delete the content of the folders :
• C:\Users\XXXX\AppData\Local\XDK\Cache
• C:\Users\XXXX\AppData\Local\XDK\File System\Origins
• C:\Users\XXXX\AppData\Local\XDK\GPUCache
• C:\Users\XXXX\AppData\Local\XDK\Local Storage

• delete files C:\Users\XXXX\AppData\Local\XDK\cookies and cookies-journal and global-settings.xdk and state.json

[XDK] Intel App Preview - intel.xdk.device.barcode.scan not executed on mobile

If you use the intel.xdk.device.barcode.scan (XDK Javascript Bridge API) in your app and would like to test on a real mobile with the App Preview, you could see the QRCode reader does not display in your mobile.

Below a few steps to solve (I create a new project):

• create a new project (type : HTML5 + Cordova) 

• on the project page, verify that field UI Framework is not "unkown"

• on the project page, uncheck all plugins

• in  app.js file write :

document.addEventListener("intel.xdk.device.barcode.scan",function(evt){
intel.xdk.notification.beep(1);    
 if (evt.success === true) {            
  //successful scan          
    console.log(evt.codedata);      
        if (evt.codedata == "http://www.sampleurl.com/fake.html")
                {  
                     //in the XDK        
       }              
 else
                {            
          alert(evt.codedata);        
       }      
 }else {            
   //failed scan        
       console.log("failed scan");  
    }
  },false);

• where you want (for exemple in your index.html), write : <script>intel.xdk.device.scanBarcode(); </script>

[Cordova] [NetBeans] npm http 404 http://registry.cordova.io/cordova-plugin-file

If you try to run for the first time an android application with Netbeans 8.0.2 and have this kind of message :

npm http 404 http://registry.cordova.io/cordova-plugin-file Failed to install 'cordova-plugin-media-capture':Error: 404 Not Found: cordova-plugin-file

Then you shoud install this plugin separately. For that, go to your project folder and type :

https://github.com/apache/cordova-plugin-file.

Now you can re-run your application under NetBeans.
