Step1 : Download ns-allinone-2.34 package .

Step2 : Place the ns-allinone-2.34.tar.gz file in under your home folder and extract it using following command

tar xvfz ./ns-allinone-2.34.tar.gz

step3 : Using command line go to this folder /home/ruzdi/program/ns-allinone-2.34

step4 : use the following command

sudo apt-get install build-essential autoconf automake libxmu-dev gcc-4.3 

change CC= @CC@ to CC= gcc-4.3 

./install

Step7: Once the installation is successful without any errors, we need to add the path information to the file ~/.bashrc

  $ gedit   ~/.bashrc 

# LD_LIBRARY_PATH
OTCL_LIB=/home/ruzdi/program/ns-allinone-2.34/otcl-1.13
NS2_LIB=/home/ruzdi/program/ns-allinone-2.34/lib
X11_LIB=/usr/X11R6/lib
USR_LOCAL_LIB=/usr/local/lib
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$OTCL_LIB:$NS2_LIB:$X11_LIB:$USR_LOCAL_LIB

# TCL_LIBRARY

TCL_LIB=/home/ruzdi/program/ns-allinone-2.34/tcl8.4.18/library
USR_LIB=/usr/lib
export TCL_LIBRARY=$TCL_LIB:$USR_LIB

# PATH

XGRAPH=/home/ruzdi/program/ns-allinone-2.34/bin:/home/ruzdi/program/ns-allinone-2.34/tcl8.4.18/unix:/home/ruzdi/program/ns-allinone-2.34/tk8.4.18/unix

# Note: the above two lines starting from XGRAPH should come in the same line

NS=/home/ruzdi/program/ns-allinone-2.34/ns-2.34/
NAM=/home/ruzdi/program/ns-allinone-2.34/nam-1.14/
PATH=$PATH:$XGRAPH:$NS:$NAM

Step9: For the changes to take effect immediately, do the following:

$ source      ~/.bashrc 

Thats all cheers …

SELECT * FROM props 
WHERE `active` = 1
AND (rent >= 25 OR price >=25) AND 1=  1
AND `props`.`id` = '1'

I found a surprising solution for this type of query. for this query i make the where clause like following –

$this->db->where('(rent >= 25 OR price >=25) AND 1= ',1); 
$this->db->where('props.id',1); 

I don’t actually know this is the fault of the developers or a feature but it is good for my work to move on.

so the total query for this SQL becomes –

$this->db->where('(rent >= 25 OR price >=25) AND 1= ',1); 
$this->db->where('props.id',1); 
$this->db->get('props');

When i was pressing duplicate key very fast then it accepts only the fast key and escape the other duplicate keys. Such as if i type “http://” then it write “htp:/”, “teen” becomes “ten” etc.

To solve this problem go to

System->Preferences->Keybord
Then go to “accessibility” tab and uncheck the “Ignore fast duplicate keypresses” under “Bounce Keys” section.

Thats it…

Failed to get the adb version: Cannot run program “/usr/src/android-sdk-linux_x86/tools/adb”: java.io.IOException: error=2, No such file or directory

After that 
1. download getlibs from http://frozenfox.freehostia.com/cappy/getlibs-all.deb
2. open terminal and go to your download folder where getlibs-all.deb is placed 
3. then on terminal use the following command —      

getlibs aapt

sudo passwd root

When you see the prompt that says “Enter new UNIX password”, enter the password you want for the root user and confirm it.
Save the file.

Click other and type your user name: root, and enter the password of root you have set.

Thats it ………
***Note this is a bad Idea to do if you are connected to the Internet while logged in as root. Any malicious scripts execute themselves with out user permissions.

gksudo nautilus

on ubuntu it is in /etc/apache2/httpd.conf and open it using

sudo gedit /etc/apache2/httpd.conf

then put your desired filename on directory index—

DirectoryIndex index.html index.htm default.htm index.php index.pl

<?php
function getBanglaDate($date){
 $engArray = array(
 1,2,3,4,5,6,7,8,9,0,
 'January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December',
 'am', 'pm'
 );
 $bangArray = array(
 '১','২','৩','৪','৫','৬','৭','৮','৯','০',
 'জানুয়ারি', 'ফেব্রুয়ারি', 'মার্চ', 'এপ্রিল', 'মে', 'জুন', 'জুলাই', 'আগস্ট', 'সেপ্টেম্বর', 'অক্টোবর', 'নভেম্বর', 'ডিসেম্বর',
 'সকাল', 'দুপুর'
 );

 $converted = str_replace($engArray, $bangArray, $date);
 return $converted;
}

?>

calling procedure is like –

<?php

 if($GLOBALS['lang'] == "bn"){
 $date = date( 'j F, Y, a g:i',strtotime($publisheddate) ) ;
 $date = getBanglaDate($date);
 }else if($GLOBALS['lang'] == "en"){
 $date = date( 'j F, Y, g:i a',strtotime($publisheddate) ) ;
 }
 ?>

So when if send a date format like  “28 July, 2010, 12:00 am”  then it returns   “২৮ জুলাই, ২০১০, সকাল ১২:০০”    date format

For tutorial you need to mod_rewrite enabled.

Step 1: setup hosts file

open /etc/hosts and add a virtual domain with a specific local IP.

Lets assume that our virtual domain name is “ruzdi.com” and It will listen to the ip “127.0.0.2″

so on /etc/hosts file we will add

127.0.0.2 ruzdi.com

now whenever you browse http://ruzdi.com your browser will actually hit http://127.0.0.2

Step2: configure virtual host with apache
Now goto /etc/apache2/sites-available and create a file named “ruzdi.com”

sudo touch ruzdi
sudo gedit /etc/apache2/sites-available/ruzdi

write the following contents inside. but please note to create the appropriate directory before linking your virtual host with that, for example we’ve create a folder named “/var/opt/ruzdi” and linked that directory as my document root in the following configuration file.

<VirtualHost 127.0.0.2:80>
        ServerName  ruzdi.com
        ServerAlias  ruzdi.com
        ServerAdmin admin@ruzdi.com
        DocumentRoot /opt/ruzdi
        <Directory /opt/ruzdi/>
                Options FollowSymLinks
                AllowOverride All
        </Directory>

</VirtualHost>

now create a symbolic link of this file to /etc/apache2/sites-enabled directory as “ruzdi.com”

sudo ln -s /etc/apache2/sites-available/ruzdi /etc/apache2/sites-enabled/ruzdi

**** here look directory location is /opt/ruzdi so you must create a directory named “ruzdi” on /opt location

Step 3: restart apache

simple, either one of the followings

sudo a2ensite ruzdi

And

sudo /etc/init.d/apache2 restart

now on your browser to http:// ruzdi.com

***This is post is similar Hasin Hyder blog post I just change a little. In my case on the hosts file port was not working so I removed it and I got everything all right.
