Last time I intalled git on my computer I had to use vi to commit every change, as Im not so good editing files width vi I opted for change the editor to nano, so to do that open a terminal and type this:
export EDITOR=nano |
Where nano is the editor to use.
There are many ways to include jquery on wordpress, there is a post here http://www.nosolocodigo.com/5-trucos-para-usar-jquery-con-wordpress that shows 5 sore of set jqeruery, but I use this way http://digwp.com/2009/06/including-jquery-in-wordpress-the-right-way/ allegedly this is the best form to do it.
This is a jQuery plugin to allow users to select multiple items from a predefined list, using autocompletion as they type to find each item. You may have seen a similar type of text entry when filling in the recipients field sending messages on facebook.

Some times we need to change the system time from shell cause we only have ssh access, so to do this we have first to have the shell access or open and the tipe this:
sudo date 032411002010.00
Where it means: March 24th 2010 11:00:00
The first 4 numbers are the month and the day (0324 – March 24th)
The follow 4 number are the time (1100 11:00 Hrs.)
The follow 4 number are the year (2010)
and the last 2 number are the seconds (00)
Its reaaly simple to do it, to send mails from our server (local or not) using postfix
Ok to do this open your terminal and type:
sudo apt-get install postfix
As you are using “sudo” you must set your admin password.
For further configuration settings, type the following into the terminal as a new command :
sudo dpkg-reconfigure postfix
That’s it.

There are many things to do this, Im going to show one way to do it width JavaScript. Here we have an example:
var FF=/a/[-1]=='a';
if(FF){
//codigo}
else {
//codigo alternativo}
//Firefox detector 2/3 FF=/a/[-1]=='a'//Firefox 3 FF3=(function x(){})[-5]=='x'//IE detector IE='\v'=='v'//Safari detector Saf=/a/.__proto__=='////Chrome Chr=/source/.test((/a/.toString+''))//Opera Op=/^function \(/.test([].sort)
B=(function x(){})[-5]=='x'?'FF3':(function x(){})[-6]=='x'?'FF2':/a/[-1]=='a'?'FF':'\v'=='v'?IE':/a/.__proto__=='//'?'Saf':/s/.test(/a/.toString)?'Chr':/^function \(/.test([].sort)?'Op':'Unknown'
there are many ways to do it, but I will show just two of them.
The first way is doing the following:
Using the wp_print_styles tag:
add_action('wp_print_styles', 'add_my_stylesheet');
function add_my_stylesheet() {
$myStyleUrl = WP_PLUGIN_URL . '/myPlugin/';
$myStyleFile = WP_PLUGIN_DIR . 'style.css';
if ( file_exists($myStyleFile) ) {
wp_register_style('myStyleSheets', $myStyleUrl);
wp_enqueue_style( 'myStyleSheets');
}
}
The second way is printing it on the header file.
add_action('wp_head', 'business_directory_css');
function business_directory_css(){
global $bizdir_relative;
echo '<link type="text/css" rel="stylesheet" href="'.get_option("siteurl") . '/wp-content/plugins/myplugin/mycssstyle.css'" />' . "\n";
}
I thing the second one is easier.
There are a function that I found in the php Manual, and it can help. To use it you must have installed curl.
Here the function:
<?php
function url_exists($url) {
$url = curl_init();
curl_setopt($url, CURLOPT_URL, $strURL);
curl_setopt($url, CURLOPT_BINARYTRANSFER, 1);
curl_setopt($url, CURLOPT_HEADERFUNCTION, 'curlHeaderCallback');
curl_setopt($url, CURLOPT_FAILONERROR, 1);
curl_exec ($url);
$intReturnCode = curl_getinfo($url, CURLINFO_HTTP_CODE);
curl_close ($url);
if ($intReturnCode != 200 && $intReturnCode != 302 && $intReturnCode != 304) {
return false;
}else{
return true ;
}
}
//example :
if(url_exists("http://php.net/manual/en/book.curl.php")) {
echo"The URL exists";
}else{
echo"The URL doesnot exist";
}
?>
