Despite the doubts in stability of the American economy in 2012, the research has showed that American companies are going to expand their IT staff. Analytics have found out what IT professions will be called for. The results of the annual research organized by Computerworld showed that 29% out of 353 IT-executive managers are planning to increase the number of their departments by the summer 2012.

‘The demand for IT-specialists in companies of all types and sizes is constantly growing’, says Mike McBrierty, the executive director of one of the biggest recruiting agencies the Eliassen Group. Moreover, according to his own words, the companies are planning to update the infrastructure and restart the realization of the projects postponed for the last 3 years.

As Computerworld claims, in 2012 the directors of IT departments have set teeth for implementing innovations and that’s why the most relevant for future employees will be the following nine main skills.

•    web and mobile application development skills
•    project management skills
•    technical support and maintenance skills
•    network technologies skills
•    business analysis skills
•    Web 2.0 technologies skills – more and more companies are planning to implement these technologies and the demand for php/java/.net software developers won’t decrease in 2012. Also there will be a big demand for Ajax GWT professional web developers as well as the specialists in .Net, PHP, HTML, XML, CSS, Flash and Javascript.

Eclipse has rolled out Orion, a new web development tool that will enable web application development in the cloud. Unlike Eclipse flagship products Orion is a browser-based tool designed to support widely-used web technologies and take these technologies to the cloud.

With WordPress conditional statements your blog will stand out against thousands of others
Conditional statements can transform themes in something unrecognizable. Be sure, your readers will be amazed by such features in Wordpress blog design. There is nothing difficult in directory conditioned elements, they based on PHP code. So with the help of php programmers you will be able to realize your ideas. For instance, welcome block at the home page can be done with the following code:
if (is_home()) {
echo ‘YOUR WELCOME BOX CODES HERE’;
} else { }

Theme framework is a timesaver for WordPress template customization
There are a lot of theme frameworks (Guerrilla Theme, Thesis, Thematic, WP Framework, etc.) that will help you to build custom templates in the shortest possible time. Use them with no hesitation!

WordPress widgets for better usability
With widgets you can easily customize the look of your theme, rearrange different blog areas (ad blocks, posts, headers, footers, etc.).

Say “no” to plugins and “yes” to PHP code
Using WordPress plugins you force end-users of your blog to download and install additional software. It’s not a good idea for quick and easy accesses to blog features and published information. PHP solves this problem and it also gives more know-hows for WordPress developers.
Continuous learning is an indispensable condition of qualitative WordPress development

WordPress has a great blogging community, it’s even more then web community. So WordPress-as-a-CMS development can be just fun and easy work with some simple plugins, php code and official teaching material from tutorial sites. You can try a simple hack code that helps to reduce spam. It blocks all comments on your blog written by users who have come with “No referrer” result (for example, spam bots).

function check_referrer() {
if (!isset($_SERVER['HTTP_REFERER']) || $_SERVER['HTTP_REFERER'] == “”) {
wp_die( __(‘Please enable referrers in your browser, or, if you\’re a spammer, bugger off!’) );
}}
add_action(‘check_comment_flood’, ‘check_referrer’);add_action ( ‘check_comment_flood’, ‘check_referrer’);

Eclipse Summit that was organized in Germany brought fresh news: Microsoft together with its partners Tasktop and Soyatec are going to release a range of tools and updates for Eclipse.

• Eclipse will support Windows 7 and all its new interface functions;
• Eclipse Standard Widget Toolkit (SWT) will be expanded to work with new features in Windows 7 and Windows Server 2008 R2;
• The open source tools Windows Azure Tools for Eclipse will be available for PHP developers;
• The open source Windows Azure Software Developer Kit (SDK) will be available for Java developers;
• The Eclipse Tools plug-in will be available for Silverlight.

So, Windows Azure SDK for Java allows leveraging Azure storage service while developing Java applications. Its logical architecture is quite simple:
It is reported that according to the voting (see The Open Source Developer Report 2009 based on Eclipse Community Survey), conducted among Eclipse users, more than 64% are using it in Windows OS. It’s obvious that PHP and Java programmers will appreciate this significant commitment from Microsoft.

The impact of recent changes in the world economy changed the situation in world of software. Now the majority of developers are focused on short-term work. But it doesn’t mean that they are careless about their prospects. Self-education and experience are still the only way to success. That is why it’s so important to be constantly analyzing existing technologies and methodologies trying to keep step with changeable IT- world, not wasting valuable time for unnecessary knowledge and superseded information.

So we will try to forecast the most essential skills for developers that won’t become obsolete in the next five-six years. In this and the next posts we will list 14 the most relevant technologies for software developers.

#1-3: Java, PHP, .NET

It’s highly unlikely that three foundations of software development, Java, PHP, .NET, will be in less demand in the near future. Developers need to know at least one of these programming languages and development platforms: Java, .NET (VB.NET or C #), or PHP. Nevertheless only one programming language syntax is not enough. Usually projects cover a wide range of different functions, so developers need to know the frameworks and libraries associated with the necessary functionality in more details.

Current version of Lightbox (widely used in web development) has an intricate navigation in the image gallery. At first a user trys to guess where to show “previous” or “next” buttons. This navigation isn’t user friendly. Here are some small modifications for creating a simple navigation:

The best way for creating it in your image gallery is overriding the code without direct changes in the lightbox source code. It’s profitable when it is necessary to update the source code.

Note: In the examples we were using lightbox2.04 in folder lightbox, the folder with the names of styles for containing css styles and the folder with the name ‘js’ for containing the java script code.

1. Creat the lightbox_override.css in the styles folder and place in it the next code snippet:

[source='php']
#hoverNav{ height: 40px; width: 100%; z-index: 10;}
#hoverNav a{ outline: none; text-align:center }

/* change height for next and previous link */
#prevLink, #nextLink{ width: 60px; height: 40px !important; background-image: url(data:image/gif;base64,AAAA); display: block; }
#prevLink, #prevLink:hover, #prevLink:visited:hover { background: url(/lightbox/images/prevlabel.gif) left 15% no-repeat;}
#nextLink, #nextLink:hover, #nextLink:visited:hover { background: url(/lightbox/images/nextlabel.gif) right 15% no-repeat;}

/* change image data container height */
#imageDataContainer{ height:40px;font: 10px Verdana, Helvetica, sans-serif; background-color: #fff; margin: 0 auto; line-height: 1.4em; overflow: auto; width: 100% ; }

#imageData{ color: #666; }
#imageData #imageDetails{ text-align: center; padding-left:60px; padding-right:60px}
#imageData #numberDisplay{ }
#imageContainer #bottomNavClose{ position:absolute; float: right; padding-top:2px; width: 17px; right: 10px;outline: none;}
[/source]

2. Creat the lightbox_override.js in the ‘js’ folder and place in it the next code snippet:
[source='php']
/**
* Override lightbox initialization.
*
*/
Lightbox.prototype.initialize = function() {

this.updateImageList();

this.keyboardAction = this.keyboardAction.bindAsEventListener(this);

if (LightboxOptions.resizeSpeed > 10) LightboxOptions.resizeSpeed = 10;
if (LightboxOptions.resizeSpeed < 1) LightboxOptions.resizeSpeed = 1;

this.resizeDuration = LightboxOptions.animate ? ((11 - LightboxOptions.resizeSpeed) * 0.15) : 0;
this.overlayDuration = LightboxOptions.animate ? 0.2 : 0; // shadow fade in/out duration

var size = (LightboxOptions.animate ? 250 : 1) + 'px';
var objBody = $$('body')[0];

objBody.appendChild(Builder.node('div',{id:'overlay'}));

// Change lightbox html code and place next and previous link to bottom of box
objBody.appendChild(Builder.node('div',{id:'lightbox'}, [
Builder.node('div',{id:'outerImageContainer'},
Builder.node('div',{id:'imageContainer'}, [
Builder.node('a',{id:'bottomNavClose', href: '#' },
Builder.node('img', { src: LightboxOptions.fileBottomNavCloseImage })
),
Builder.node('img',{id:'lightboxImage'}),
Builder.node('div',{id:'loading'},
Builder.node('a',{id:'loadingLink', href: '#' },
Builder.node('img', {src: LightboxOptions.fileLoadingImage})
)
)
])
),
Builder.node('div', {id:'imageDataContainer'},
Builder.node('div',{id:'imageData'}, [
Builder.node('div',{id:'hoverNav'}, [
Builder.node('a',{id:'prevLink', href: '#' }),
Builder.node('a',{id:'nextLink', href: '#' }),
Builder.node('div',{id:'imageDetails'}, [
Builder.node('div',{id:'caption'}),
Builder.node('span',{id:'numberDisplay'})
])
])
])
)
]));

$('overlay').hide().observe('click', (function() { this.end(); }).bind(this));
$('lightbox').hide().observe('click', (function(event) { if (event.element().id == 'lightbox') this.end(); }).bind(this));
$('outerImageContainer').setStyle({ width: size, height: size });
$('prevLink').observe('click', (function(event) { event.stop(); this.changeImage(this.activeImage - 1); }).bindAsEventListener(this));
$('nextLink').observe('click', (function(event) { event.stop(); this.changeImage(this.activeImage + 1); }).bindAsEventListener(this));
$('loadingLink').observe('click', (function(event) { event.stop(); this.end(); }).bind(this));
$('bottomNavClose').observe('click', (function(event) { event.stop(); this.end(); }).bind(this));

var th = this;
(function(){
var ids =
'overlay lightbox outerImageContainer imageContainer lightboxImage hoverNav prevLink nextLink loading loadingLink ' +
'imageDataContainer imageData imageDetails caption numberDisplay bottomNav bottomNavClose';
$w(ids).each(function(id){ th[id] = $(id); });
}).defer();
};

Difference between standard initialization and custom is in changing html element positions.

3. Include the standard litebox files:

[source='php']

4. Include the ‘css’ customization:

[source='php']

5. Include the java script logic customization:

[source='php']

Note: all files included must be located in the head element of the html page.

Home page: www.doctrine-project.org. Current version: 1.0.2

Doctrine requires PHP 5.2.3+. It doesn’t require any external libraries. For the database function call abstraction Doctrine uses PDO which comes bundled with the PHP official release that you get from www.php.net.

Doctrine features:

• Supports: MySQL, SQLite, PostgreSQL, Oracle, Mssql, Firebird and Informix.
• Supports result caching with Memcache, APC or SQLite.
• Supports import/export with YAML schemas, SQL scripts or existing database.
• Has DQL (Doctrine Query Language) it helping users in complex object retrieval.
• Supports migration functionality. For making a migration process easy.
• Has integrated searching functionality.

Example:
This example illustrates the way of extracting data from the database table.

File structure:
Models/
Users.php – user model
Doctrine/ - Doctrine library files
Doctrine.php – Doctrine main file
index.php
Example of index.php
[source='php']
// include Dotrine main file.
require_once 'Doctrine.php';

// register Doctrine library file loader.
spl_autoload_register(array('Doctrine','autoload'));

// connect to database
Doctrine_Manager::connection('mysql://user:password@localhost/database');

// set path to models
Doctrine::loadModels('models');

// create simple query on DQL.
$users = Doctrine_Query::create()->from(‘Users’);

// print result
foreach ($users as $user)
echo $user->email;
?>
[/source]

Example of Users.php
[source='php']
/**
* User model definition.
*/
class Users extends Doctrine_Record
{
/**
* Define model metadata.
*/
public function setTableDefinition()
{
$this->setTableName(‘users’);

$this->hasColumn(
‘id’,
‘integer’,
4,
array(
‘type’ => ‘integer’,
‘length’ => 11,
‘primary’ => true,
‘autoincrement’ => true
));

$this->hasColumn(
‘email’,
’string’,
255,
array(
‘type’ => ’string’,
‘length’ => 255,
‘default’ => ”,
‘notnull’ => true
));
}
}
?>
