recover kopete password

I was trying to recover a password from a kopeterc file.

Open the kopeterc file in a hex editor
In the password location you will find three-byte chunks: [EF][BE][XX]. The first two bytes stay most of the time same.
Just subtract each third byte from 0x1001F then you will get the character value from ASCII table.

everything was working fine as mentioned in Raphman's blog

But I had a little problem with numeric value. My combination was "EF BE XX" but before the numeric value it was "EF BF XX".

For the numeric value I have to subtract 0x40 again to get the original value.

It worked for me at last...

get database structure using PHP

I was facing problem to connect a mysql host, as it was only accepting connection from a specific server. But I need to know the database structure to design some report.

At last I have written a simple php code to print the table name along with the structure.

<?php
   
   mysql_connect("host_name","user","password") or die(mysql_error());
   mysql_select_db("database_name") or die(mysql_error());


   $result = mysql_query("SHOW TABLES;") or die(mysql_error());  

   while($row = mysql_fetch_array($result)){
  
 echo $row[0]; //print the table name
 
 $result2 = mysql_query("DESCRIBE ".$row[0].";") or die(mysql_error()); //get details schema for each table
 
 echo "<table border='1' width='70%'>";
 echo "<tr><td>Field</td><td>Type</td><td>Null</td><td>Key</td><td>Default</td><td>Extra</td>";
 
 while($row2 = mysql_fetch_array($result2)){
   
  for($i=0; $i<6; $i++){ 
   if($row2[$i] == "" || $row2[$i] == NULL){
    $row2[$i] = " ";
   }
  }   
   
  echo "<tr>";
  echo "<td>".$row2[0]."</td><td>".$row2[1]."</td><td>".$row2[2]."</td><td>".$row2[3]."</td><td>".$row2[4]."</td><td>".$row2[5];
  echo "</tr>";
 }
 
 echo "</table>"; 
 echo "<br/>";
}

?>

Just change your database configuration then upload in your server. Browse the url and you must delete the file from server after get the structure. Be safe...

function call in javascript

I was studying russkey.mozdev.org source code to learn how to write Firefox extension.

Found this style of function call in javascript.

var collection =   {

 hello : function() {
  document.write("Hello World!");
 },
 
 understand : function() {
  document.write("<br/>Understand!");
 },
 
 bye : function() {
  document.write("<br/>bye!");
 }
 
};


var m = new collection.hello();
var n = new collection.understand();
var o = new collection.bye();

The output will

Hello World!
Understand!
bye!

flash/swf height width in CodeIgniter 1.6

In libraries/Upload.php

Edit the function is_image().

add the 'application/x-shockwave-flash' in $img_mimes

$img_mimes = array(
 'image/gif',
 'image/jpeg',
 'image/png',
 'application/x-shockwave-flash',
);

It simply allow set_image_properties function to read the height & width for flash.

//now this will not call for flash
if ( ! $this->is_image())
{
return;
}
