Search Portlet

Few months ago I was developing a project on top of JBoss Portal. Unfortunately, JBoss Portal 2.7.x is a nice Portlet Container but a crappy CMS/Search engine -even when it is supported on Apache’s JackRabbit. However, I was forced to develop a search portlet. It wasn’t easy, and you will probably find that it is not a perfect solution. However I really hope you find this Search Portlet really useful.

I used two JSP pages to support this portlet.

  • search.jsp – Search form – the standard portlet view
  • results.jsp – Results list page – appears with the portlet MAXIMIZED and displays CMS files that matches the criteria

I Ditched Windows…and, So Can You

etiqueta_ubuntu4I bought a new desktop computer like a week ago, a nice desktop PC with a beautiful 22″ screen. The truth is that I was looking for an iMac 24″, but unfortunately here in Colombia it could be have an overprice of USD$500 ~ USD$1000. So as you can tell it could be a trip to U.S. with an iMac on your baggage. I talked to some of my friends and coworkers asking for somebody to bring it, but it wasn’t possible this time -at least shortly.

So I bought a nice computer with Windows Vista Home Premium -as usual and some useless stuff like a remote and MediaCenter. I tried it few days and Vista did its magic -slowing down the newest computer even faster than I thought- so I moved to Windows 7 (64 bits version) -Oh Yeah it is like Windows Vista but better (like G.M. TV commercials with their cars).

A week ago, and after doing a realistic evaluation of my computing needs I decided to switch to Ubuntu 9.04 (64 bits version) and mount a VM with Windows XP Home to keep testing on Internet Explorer 6.0. It was a HUGE improvement in performance – I just remembered D.O.S. days when programs run immediately after being called. Ubuntu offers a lot of advantages in compare to Windows, but obviously we are so attached to Microsoft pseudo-world that just thinking on the switch could be a nightmare. I will not debate on architecture, security or speed. I’ll say this as clear as possible. If you do not have to use MS products like Exchange, or you do not have to use speciallized software that runs on Windows -like AutoCAD or Adobe CS4- you can just switch without fair, it will be the reinvention of the computer processing performance.

There are a lot of Linux Distributions in the market -like Ubuntu- but I have to say that Ubuntu is for soft-users and not hard-crazy linux fans. Ubuntu is nice, is really REALLY REALLY easy to install and if you aren’t sure about replacing your desktop with it, you can try Wubi -it installs Ubuntu as a Windows application -WOW!

Just to clarify, I had been using Ubuntu and other linux distributions for a long time (Fedora is another one) but it is the first time I decided to switch to Linux WITHOUT a Windows partition. My wife -who is a dentist- hates its portable due to its response time, and I did all the normal-not-so-risky tasks to speed up its XPS 1210 (that used to be mine) with Windows XP Home Edition, today we had our first class about linux and she is so happy about the speed and performance, and also the virus/crappy-sw situation that isn’t a critical issue on Ubuntu (Linux) so she is thinking seriously about moving to Ubuntu her portable too.

“So, if you’re using Windows and want to ditch it, click here to begin a less stressful life”

IMPORTANT NOTE: I decided to write this post when a friend of mine sent me a link to a post who has the same title of this one. Thanks to Gregory Ferenstein for such inspiring post -I did’t move to Linux because of his post, but I makes me feel like “I’m not alone, I’m not just a crazy guy that hates Microsoft, I’m not a linux fanboy… we are just right about Windows: it sucks!


How to choose the right project management software?

Choose RightTo choose the right software is not a simple process, and to choose the right project management software is then an even more complicated process and decision. Below you will find few tips and proposed procedure to reduce the risk inherit to this decision.

Tip #1

To choose and implement a PM software tool is not the same of implementing a PM process. Many organizations try to implement a software tool expecting a nonexistent-unnatural process improvement. If you do not have a formal process, or even if your process is not working you have to stop thinking that automation will fix/improve/solve your problems. Automation should be used to reinforce a process and minimize the weaknesses.

Tip #2

Every software implementation process includes at least the following steps -of course every company has its own natural process. Public companies have also additional restriction and evaluation/validation processes that will extend the suggested process:

  • Identify needs
  • Define selection criteria
  • Create a list of options
  • Create the request for information
  • Evaluate responses
  • Reduce the list of options
  • Ask for demonstrations or pilot programs
  • Choose one

Tip #3

Try to isolate your needs by using the following dimensions to measure the products you are considering:

  • Scale – how big the change will be?
    • Simple: are you going to organize your projects?
    • Personal: are you going to automate estimation and planning on you projects
    • Collaborative: are you going to support a team? are you going to share information? do you need to centralize team communications?
    • Enterprise: are you affecting the whole company? are you going to bill to your clients using your projects’ data? do you have virtual teams all around the globe?
  • Management Paradigm – do you and your team follow a traditional or agile approach to project management?
  • Process Maturity – how formal/strong is your process?
    • Chaotic: No evidence of documented processes or best practices
    • Active: Documented processes carried out, but not formalized
    • Efficient: Consistent discipline started
    • Responsive: Ubiquitous and measured
    • Business driven: Provides data and information to drive business decisions
  • Implementation model – are you going to buy the product and support it by yourself? are you going to adopt the SaaS model?
  • Budget -

Tip #4

Set your goals – do not expect to do everything better and to include any improvement during the first phase (or the initial implementation cycle). Prioritize to get faster results. Below you will find a list of possible goals that you could address with a PM software tool

  • Improve project reporting and tracking
  • Improve estimating and scheduling
  • Reduce cost or speed process up by automating workflows
  • Improve resource assignments
  • Improve project communication
  • Improve project team collaboration
  • Improve overall project process

Every goal will impact different functional areas within an organization. You should plan your implementation to impact those areas and improve those process that will add the most value.

Facebook & CodeIgniter – Definitive Guide

I spent more hours than the expected starting a simple development for a new Facebook application that runs on top of CodeIgniter. First I read A LOT, then I checked for solutions and, of course, I read a little bit more. After several hours reading and coding I knew it wasn’t good at all so I decided to start a new integration method from the scratch using only the code I found as guide. Here’s the result:

0. Environment

Before you get excited just review a few things before spent time reading another useless post :-)

  • PHP Version 5.2.6
  • MySQL 5 (It doesn’t affect Facebook integration at all but it is good to know)
  • HostMonster is my hosting provider (it is not a marketing initiative, just they have a nice environment set up for PHP)
  • Facebook platform 5 – I upload a copy of it to ensure you get the same copy I used.
  • CodeIgniter 1.6.3 – latest version available at the time of this post.

1. Do not hack CodeIgniter

I found a lot of solutions about hacking CodeIgniter by overriding functions or classes. NO, YOU DO NOT HAVE TO DO IT.

2. Install facebook library as plugin

  • Download the facebook platform ZIP
  • Unzip the files wherever you want -outside your Code Igniter application
  • Copy the WHOLE content under /php folder (under means files inside the folder and not with the container folder) to yout ./system/plugins folder inside Code Igniter application -Note: Yes, you have to include the jsonwrapper folder.
  • Rename the facebook.php file to facebook_pi.php

It is done! You already have installed facebook framework as plugin.

3. Autoload facebook plugin [optional]

To avoid the need of including the “load plugin” sentence inside every controller/class you can modify the ./system/config/autoload.php to include facebook plugin as required. It is almost a requirement for Facebook applications. Add to your $autoload['plugin'] array the facebook plugin. It could look like this:

$autoload['plugin'] = array('facebook');

Note: If you skip this step you will have to include the following line every time you need facebook functionality available.

$this-&gt;load-&gt;plugin('facebook');

4. Setup your application [updated]

Update your configuration file and set the ./system/application/config/config.php and change it as follows:

$config['uri_protocol'] = "PATH_INFO";
$config['base_url'] = "APPLICATION_URL";

Note: If you want to test your application locally, you can set base_url to http://127.0.0.1/path_to_your_app/

5. Extend your Controller class

Because I’m building a 100% facebook application, all my controllers require facebook API available. So I decided to extend my main Controller class as follows – BTW: By the date of this post the CodeIgniter documentation WAS WRONG about how to extend the core classes (CodeIgniter User Guide Version 1.6.3 – Creating Core System Classes). It is not true -i.e. it is false- that you have to extend the CI_ClassName. At least it didn’t work for me at all. Extend the ClassName directly.

Facebook Controller class should be placed under ./system/application/libraries folder.

Filename: XX_Controller.php (where “XX_” is the prefix you set on your ./system/application/config/config.php file – subclass_prefix parameter)

class FB_Controller extends Controller {
 
	// Facebook application key
	var $API_KEY = 'YOUR_API_KEY';
 
	var $facebook;
	var $uid;
 
	/*
	 * Custom Controller constructor.
	 * Adds Facebook support.
	 *
	 */
	function FB_Controller() {
 
		parent::Controller();
 
		// Authentication key
		$secret = 'YOUR_SECRET_KEY'; 
 
		// Prevent the 'Undefined index: facebook_config' notice from being thrown.
		$GLOBALS['facebook_config']['debug'] = NULL;
 
		// Create a Facebook client API object.
		$this-&gt;facebook = new Facebook($this-&gt;API_KEY, $secret);
		$this-&gt;uid = $this-&gt;facebook-&gt;require_login();
	}
}

Note: Inside the facebook application I built I always require an authenticated users, so that’s why I do have the require_login() call. However you can also validate if the user already have the application added. You should do this manually inside controller classes because there are a few exceptions where it is needed that user is authenticated but without adding the application.

6. Create your own controllers

Now you can extend your controllers from your Custom Controller. Note: You do not have to add any include or require sentence in your other classes, CodeIgniter will load directly your XX_Controller.php file -if it doesn’t load please check the config.php file and validate the subclass_prefix parameter.

Below you will find an example of a Controller that will validate if the user has the application added in his/her profile.

class Welcome extends XX_Controller {
 
	function Welcome() {
 
		parent::XX_Controller();
 
		// Check if the application has been added by the user
		try {
			if (!$this-&gt;facebook-&gt;api_client-&gt;users_isAppAdded()) {
				$this-&gt;facebook-&gt;redirect($this-&gt;facebook-&gt;get_add_url());
				return;
			}
		}
		catch (Exception $x) {
			// Clear cookies for your application and redirect them to a login prompt
			$this-&gt;facebook-&gt;expire_session();
			$facebook-&gt;redirect($this-&gt;facebook-&gt;get_login_url());
		}
	}
 
	// You should place your Controller's methods below.
 
}

7. Get out and celebrate

CodeIgniter is running as cleaner as you expected and Facebook API was included nicely!

I hope you find this post useful as I said at the beginning.
