Finally, I managed to bring my presentation to the Internet. I have made a few presentations recently but never publish them :D , this is the first one

This presentation I made on Saturday with my group in Information Management subject. The topic is about integrating company Mission, Goals and Objectives into its Enterprise model(s). A guideline to define objectives for enterprise processes and activities, the benefits would be an objective-oriented enterprise and you can control the processes in a better manner. Any information or discussion is welcomed.

Here is a way to allow you to extend Symfony 2 Form using tagged Service. I think it's the correct way but not yet documented on the book. Symfony 2 is still brand new and the document is not completed yet, I found out this solution while diving into Symfony Form component

Well, the code is quite simple. You need to create a service tagged with form.type_extension with alias value is the type of Form element you want to override. Then make the service inherits from Symfony\Component\Form\AbstractTypeExtension, implement the getExtendedType method to return the same value with alias and then override the buildForm method to do whatever you want with the Form. Here is an example to illustrate how to add more field to a form

services.yml

services:
  demo.form_extension:
    class: Demo\MyBundle\Form\Extension\MyFormExtension
    tags:
      - {name: form.type_extension, alias: form}

FormExtension.php

namespace Demo\MyBundle\Form\Extension;
 
use Symfony\Component\Form\FormEvents;
use Symfony\Component\Form\FormBuilder;
use Symfony\Component\Form\AbstractTypeExtension;
 
class MyFormExtension extends AbstractTypeExtension
{
	public function buildForm(FormBuilder $builder, array $options)
	{
		// TODO: add some check for the form you want to use here
		$data = $options['data'];
 
		// extend the form here, you can also use custom validator
		$builder->add('new_item', 'text');
 
		$builder->addEventListener(FormEvents::POST_BIND, function($event) {
			$form = $event->getForm();
 
			// do whatever you want here, such as additional data binding
		});
	}
 
	public function getExtendedType()
	{
		return 'form';
	}
}

Note: Symfony 2 also has form.extension, you can use it to load form type or extension by PHP. Check Symfony/Component/Form/Extension/Csrf namespace for example.

This is my final report for Business Process Management course. I have finished it quite a long time ago, and now I would like to post it to my blog. This report is about finding an aproach to automate the conversion from UML Activity diagram to BPMN model based on well-defined rules and context. The goal is to be able to synchronize BPMN models with business system.

I am quite new to this area so I am not completely sure that the information in the report is 100% correct. Most of the idea is from this report, I added my idea, add more translation rules and suggestion some further approach for the translation. This is my first formal english report that I did only on my own. I think it is somewhat a paper but not really sure if it satisfy the condition to be a paper, hehe. I hope it would be useful for someone.

Any suggestion, discussion or typo correction is always welcome

I just released ChromeSniffer 0.2.9. This is a minor update for chromesniffer after few months. This release fix broken icons on linux, improve YUI, Wordpress, Moodle detection. The following applications are added to detection list:

• OpenCart
• Sitefinity
• Shibboleth
• SiteCatalyst
• Coremetrics
• Twitter and Buzz buttons
• Google Loader
• HeadJS
• RightJS
• Humans TXT

This release is also the first release driven by community. Most of the commits are contributed by community. Many thanks to onlineamateur, kevtufc and nb.

There is no roadmap for 0.2.10 yet, but I am thinking about to extends ChromeSniffer to support to detect additional information of the site too, such as detect for site microfotmat or RDF. CSS framework will be considered too. The goal for chromesniffer will be a tool for developer to have an overview of the technology on the site. If you have any idea, feel free to send me your idea via the contact form.

Just a very quick post for new comers to Ubuntu who is looking for a way to install rar extension. RAR extension (should be php5-rar) is not available on Ubuntu official, apt-get install php5-rar won't work, not sure why. If you want to install it then you can use PECL from PEAR instead, as following:

$ sudo apt-get install php5-dev php-pear g++
$ sudo pecl install rar

Then you will need to edit php.ini to include rar.so, it should be placed somewhere in /etc/php5. You should be able to install any extension on PECL using pecl command too. But anyway, package from Ubuntu repository is recommended.
