4.Download flasher from here: http://tablets-dev.nokia.com/maemo-dev-env-downloads.php?f=maemo_flasher-3.5_2.5.2.2.exe
5. Install flasher in your pc.
6.Copy the downloaded pr1.2 image file to the flasher installed location. that would probably be at C:\Program Files\maemo\flasher-3.5 folder.
7.Open command prompt.
8.Change the directory to the flasher using the command cd C:\Program Files\maemo\flasher-3.5
9.Switch off your device and then press and hold the u key on the n900 keyboard and connect your usb cable to the pc and your n900. Your device should be now set to the flashing mode. A usb icon should appear on the upper right hand corner.
10. Run following command on the command prompt.
flasher-3.5.exe -F RX-51_2009SE_10.2010.19-1_PR_COMBINED_MR0_ARM.bin -f -R
This should execute a series of command and reboot your n900 to latest pr1.2 maemo successfully.

Function for generating breadcrumb

first parameter an array with key and values, value is used for link where as keys are used for link name.

second optional parameter for sending class of ul in the breadcrumb listing.

<?php
function breadcrumb_generate($paths = array(), $ul_class = 'breadcrumb')
{
	$forward_icon = '<img src="'.base_url().'images/front_img/icons/forward.png" alt="&raquo;" />';
    $breadcrumb = '<ul class="'.$ul_class.'">';
	$i=1;
	$total_paths = count($paths);
	foreach($paths as $path=>$link)
	{
		if($link!='nolink')
		{
			$breadcrumb .= '<li><span><a href="'.site_url($link).'">'.$path.'</a></span></li>';
		}
		else
		{
			$breadcrumb .= '<li><span>'.$path.'</span></li>';
		}
		$i++;
	}
	$breadcrumb .= '</ul>';

	return $breadcrumb;
}
?>

usage

<?php echo breadcrumb_generate(array('Home'=>'', 'Group'=>'group/browse', ucfirst($row->name)=>'group/'.$row->permalink, 'Forum'=>'group/'.$row->permalink.'/topic', $topic_row->title=>'nolink'), 'topicBreadcrumb');?>

css styles for listing breadcrumbs

ul.breadcrumb{
	padding-top:5px;
	width:400px;
}
ul.breadcrumb li{
	float:left;
	list-style:none;
	background:url(../images/front_img/icons/forward.png) no-repeat 0.2em 0;
	padding-left:17px;
}
ul.breadcrumb li span{
	padding:5px;
}
ul.breadcrumb li span:hover{
	padding:4px;
	border:1px solid #090;
	-moz-border-radius:5px; -webkit-border-radius:5px;

}
ul.breadcrumb li:first-child{
	background:none;
	padding-left:0px;
}

This is just a rough usage of this function. you can hack it up and use as needed.

1. set the locale in the theme header.php file.
   setlocale(LC_ALL, ‘es_ES.UTF8′); //at the very top of the theme header file.
2. using strftime function to change the time in the wordpress loop function.
   <?php echo strftime(“%A, %d”,strtotime(get_the_time(‘d M Y’)));?> de <?php echo strftime(“%B”,strtotime(get_the_time(‘d M Y’)));?> de <?php echo strftime(“%Y”, strtotime(get_the_time(‘d M Y’)));?>

This was how i set the locale for time to spanish in wordpress. if you have better ways out please comment.

	}

	function check_username_exist($username)
	{
		//connect to database and find the category
		include(APPPATH.'config/database'.EXT);

		$conn = mysql_connect($db['default']['hostname'], $db['default']['username'], $db['default']['password']);
		mysql_select_db($db['default']['database'],$conn);
		$sql = sprintf("SELECT COUNT(id) as count FROM users WHERE username = '%s'", mysql_real_escape_string($username));
		$query = mysql_query($sql);
		$row = mysql_fetch_object($query);
		mysql_close($conn);
		if($row->count)
		{
			return TRUE;
		}
		return FALSE;
	}
}

The above code checks for the username in database table user and routes them to controller user/profile. Offcourse you could use simple routing rules but there can be case when you specifically route for the records in the database only. So this method comes handy in that condition.

Recently i needed to use phpQuery in one of my project based on codeigniter. I would like to show you ease of usage of phpquery for dom manipulation and getting it to work with codeigniter. First get the phpQuery http://code.google.com/p/phpquery/

Extract the phpquery you will get several folders like api-reference, cli, jqueryServer, phpQuery, test-cases.. copy the phpQuery  folder and drop it in to libraries folder of you codeigniter application.

Now to use it in any of your controller.

do this:

class PhpQueryTest extends Controller{

function PhpQueryTest(){

parent::Controller();

}

function index(){

//include phpQuery for dom manipulations
require_once('application/libraries/phpQuery/phpQuery.php');
//getting html from url
$html = @file_get_contents('http://www.yalamber.com');
//response from the curl
$html = $response;
$doc = phpQuery::newDocument($html);

//getting title of the url

$title = $doc['title']->text();

echo 'title of the site is '. $title;

//here title is the selector you can use any selector like # for id and .(dot) for class similar to jquery and the function like text(), html() etc similar to jquery. I will add more tutorial on phpquery like getting video embed code from site and other parts later.

}
