Dynamically add a group of fields using jQuery

2012-02-12T12:03:00.000+06:00

Its not a so tough thing, tough. Just wanted to keep a record and add a tip :) Following is the code I am using:

Note:
I was facing a problem, when the groups of fields grows more then the view area for each click to create the window jumps to the top of the page; To resolve, to remain where I was creating the new fields I just added one line return false as the last line of the click even.
Instead of remaining the same place if you want to scroll to some where else you can use the following jQuery plugin:
scrollTo

Manipulating Auto Increment values in MySql

2012-02-08T13:43:00.000+06:00

Set the MySql variables auto_increment_increment and auto_increment_offset variables.
Play with the Auto_Increment in Information schema.

To start with an AUTO_INCREMENT value other than 1, you can set that value with CREATE TABLE or ALTER TABLE, like this:

ALTER TABLE tbl AUTO_INCREMENT = 100;

Note:It is not possible to confine the effects of these two variables to a single table, and thus they do not take the place of the sequences offered by some other database management systems; these variables control the behavior of all AUTO_INCREMENT columns in all tables on the MySQL server. If the global value of either variable is set, its effects persist until the global value is changed or overridden by setting the session value, or until mysqld is restarted. If the local value is set, the new value affects AUTO_INCREMENT columns for all tables into which new rows are inserted by the current user for the duration of the session, unless the values are changed during that session.

Unload/Uninstall Trend Micro Office Scan client 10.5

2011-12-20T23:33:00.000+06:00

I wonder why to block the everything instead of trying to grow the culture for trust and reliability and ownership ? I wonder why this freaking Trend Micro's Office Scan to narrow down the accesses ?! I was ok with it untill when they locked access to my external devices which is really essential for me to back all my things up. After couple of google here is the solution I got to Unload(disable) or Uninstall Trend Micro Client where a prompt comes up for a password.

Go to the ..\Trend Micro\OfficeScan Client directory. Usually, it would be:

C:\Program files\Trend Micro\Officescan Client\

Locate and open the Ofcscan.ini[this is the file where all the configuration setting for the OfficeScan client is stored ] file using any text editor. You may use notepad to edit.

Find [INI_CLIENT_SECTION] section.

Change the value of the Uninstall_Pwd to

!CRYPT!523F7DC2E525044E2800FCDEA7E5D78B70C0A4165387060525E3EE66D5D2D2F460EA361E712B5F871FD473C7A6C

Change the value of the Unload_Pwd to

!CRYPT!523F7DC2E525044E2800FCDEA7E5D78B70C0A4165387060525E3EE66D5D2D2F460EA361E712B5F871FD473C7A6C

Save and close the file.
Right click on the Officescan client on your system tray then click on Unload Officescan
Once it prompts you for the password type trendmicro as the password.

You should be able to see your officescan client on the system disappear. Now you are free from all the blocking imposed by this tool. I can access my external devices... o la la :D

Note:

If you can't save the Ofscan.ini file [windows 7] open the editor as administrator - right mouse on the editor program and click run as administrator.
If Client_Allow_Uninstall / Client_Allow_Unload set to 0 make it 1.
If UnloadProtect is set to 1 make it 0.

My Instant Continuous Integration environment for development

2011-12-07T15:50:00.001+06:00

A simplest dev environment for continuous integration for a dev team [considering a php project with mysql db] :
1. Install Visual SVN server - its for windows and easy to install and manage SVN server.
2. Create a post commit hook for the repo; to do that - In the VisualSVN Server GUI Tool:
-Select your repository
-Right click Properties Select the Hooks tab
-Select the Post-commit hook
-Click the Edit button.
-Enter a line like this into the textbox:

c:\program files\visualsvn server\bin\svn.exe" export https://svn.yourserver.com:4433/svn/YourRepository/Websites/YourWebsite/ C:\inetpub\wwwroot\YourWebsite --quiet --non-interactive --force --username youruser --password yourpassword

-Click Ok.
3. Now for the DB Sync follow the steps in the following article : [However, you might need some modification to meet your need]
http://www.decodephp.com/2008/09/29/svn-and-mysql-schema-synchronization/

Surely, You can add more flavor to this environment, like you can add a script to run each day so that it grabs all the commit logs and emails to the test team and/or stack holders or may to the entire team - so that everybody remains better informed.

Hope this will help us a to remain synced in an Agile team.
Those who is not aware of the term Continuous Integration, you can check this wikipedia link

Installing php driver for MongoDB

2011-11-13T13:05:00.001+06:00

&

This is the post where I will configure php to work with mongoDB. On my previous post I have put the teps I followed to install mongoDB on my Ubuntu [TurnKey Linux] running on VirtualBox.
1.Run:

sudo pecl install mongo

2.Open your php.ini file and add to it:

extension=mongo.so

It is recommended to add this to the section with the other "extensions", but it will work from anywhere within the php.ini file.
3.Restart your web server (Apache, nginx, etc.) for the change to take effect.
Note:
pecl requires that pear be installed. For those using apt-get, you may need to run the following:

sudo apt-get install php5-dev php5-cli php-pear

However, you can download the source for the driver and can compile it manually :

shell> tar -xzvf mongo-1.2.6.tar.gz
shell> cd mongo-1.2.6
shell> phpize
shell> ./configure
shell> make
shell> make install

Check with the phpinfo

Starting MongoDB and php on Ubuntu

2011-11-13T12:40:00.001+06:00

Installing MongoDB on Ubuntu:

1. Add 10gen package to source.list
The 10gen package contains the latest mongoDB version, append below line to the end of the file “/etc/apt/sources.list”

deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen

For example, you can vim the “source.list” and append the 10gen package like this :

$ sudo vim /etc/apt/sources.list

File : /etc/apt/sources.list

#...content omitted ...
## This software is not part of Ubuntu, but is offered by third-party
## developers who want to ship their latest software.
deb http://extras.ubuntu.com/ubuntu natty main
deb-src http://extras.ubuntu.com/ubuntu natty main
#mongo repo ##########
deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen

2. Update package
Update the modified “/etc/apt/sources.list” :

sudo apt-get update

Now, a new “mongodb-10gen – An object/document-oriented database” is available for install.

3. Add GPG Key

10gen package required GPG key, import it :

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv 7F0CEB10

4. Install mongodb-10gen

Everything is ready, now you can Install the mongoDB package :

sudo apt-get install mongodb-10gen

5. Post-InstallationVerification

Now, mongoDB is installed, started, and auto start mongoDB script is generated to “/etc/init/mongo” and “/etc/init.d/mongo“. In addition, all mongoDB files are copied to “/usr/bin” folder.

The main configuration file “mongodb.conf” is located at “/etc/mongodb.conf“, change the values to customize your mongoDB server.

File : mongodb.conf

# mongodb.conf
# Where to store the data.
# Note: if you run mongodb as a non-root user (recommended) you may
# need to create and set permissions for this directory manually,
# e.g., if the parent directory isn't mutable by the mongodb user.
dbpath=/var/lib/mongodb
#where to log
logpath=/var/log/mongodb/mongodb.log logappend=true
#port = 27017
#......

6. Verification

To verify it, just connect it with “mongo”

$ mongo
MongoDB shell version: 1.8.1connecting to: test
>

on my next post I will try to connect php with this mongoDB.

Parsing Email with PHP

2011-11-04T18:34:00.002+06:00

I was working for a Email Advertisement tool,recently. And the first thing I was put to work with is to develop a parser that parses and incoming email and decides whether it is a bounced back email. After couple of googling I got some fare enough solution that I wanted to use for the solution. The steps I followed for the solution are adopted from the following :
HOWTO: Email Bounce handling with PHP, Exim & CPanel, Catch bounces from non-deliverable emails

And the very basic parser I wrote can be downloaded from the following location:
Download the email parser for bounce management
[Bascially It's a codeIgniter controller, but you can use it as you wanna use it]

However, I had to go some more details parsing, later to decide the type of bounce or the reason for the bounce.First I tried parsing the log file for the exim [exim_mainlog file] and then parsing the entire body of the bounced back emails. I will share two more posts on them in this series.

Hack a Blackberry 9700 Bold to access internet without BlackBerry data service

2011-10-03T10:23:00.000+06:00

[I kept this post for long as Draft; thought I shud l publish; ]
Playing with the Blackberry 9700 from Sujoy who was not using it because it cost a lot to enable Blackberry service with the Operators who are offering BB services.

So I picked it up just to see why should such a device left unused just because some kinda service is not available or bcz its expensive. Following are the things what I am currently doing with it :

Setting the Internet connection without the Blackberry data service :
First of all you have to set up your tcp settings. In your BlackBerry menu go to => Options - Advanced Options - TCP and enter your APN information for your GSM Service.You can ask your customer care for the APN information.When you finish the settings you need a browser to surf the net. The best one is Opera Mini Browser. You download the Opera Browser to your BlackBerry and in the Opera Browser menu you go through automatic network setup. Once the Opera Browser finds out your settings you are ready to surf the net from you BlackBerry for free. (Excluding standart connection charges- for the GPRS/Edge from your GSM service provider)

Happy, browsing then without paying the BB service :P.

Node.js : Simple push from server to browser

2011-07-02T13:38:00.000+06:00

Here you go a test that a tasted while playing with Nodejs.I must say that it is a great fun playing with Nodejs.I always love to create real time environment for the web. Here is a little example of it. With this piece of code you'll be able to monitor any changes in a file in real time directly from your browser. Nothing too efficient but still a very good start.

My flavor : On this video you will see Pedro is using a log file. Instead, I used a simple text file and updated the file manually.

Issue I faced : Din work for me on google chrome but was good on firefox. After investigation here seems a little convincing reason :
http://stackoverflow.com/questions/6068820/node-js-problems-with-response-write

For getting started with Node.js, You'll get a complete set of video tutorials at the following location :

Simple Hacks for windows using regedit

2011-07-02T12:57:00.000+06:00

Following is a list of some interesting restrictions, which can be made in Windows 2000, XP, 2003, Vista, 2008 and 7. Like you can restrict Display properties, task bar properties, folder options, etc. All tricks are based on Registry editing. So I'll tell the key name and the value, that you have to create for the restriction. If the key is not present, then simply create it.

1.) Restrict Display Properties:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\System
create DWORD value NoDispCPL and set its value to 1

2.) Restrict Taskbar Properties:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer
create DWORD value NoSetTaskbar and set its value to 1

3.) Restrict Folder Options:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer
create DWORD value NoFolderOptions and set its value to 1

4.) Restrict Locking/Unlocking the taskbar:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer
create DWORD value LockTaskbar and set its value to 1

5.) Restrict Active Desktop:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer
create DWORD value NoActiveDesktop and set its value to 1

6.) Restrict adding/deleting items from Toolbars:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer
create DWORD value NoToolbarCustomize and set its value to 1

7.) Restrict adding/deleting toolbars:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer
create DWORD value NoBandCustomize and set its value to 1

8.) Restrict right-click in Start Menu:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer
create DWORD value NoChangeStartMenu and set its value to 1

9.) Restrict Desktop Cleanup Wizard:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer
create DWORD value No Desktop Clean up Wizard and set its value to 1

10.) Restrict notification at low disk space:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer
create DWORD value No Low Disk Space Checks and set its value to 1

11.) Restrict Taskbar Context Menu:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer
create DWORD value No Tray Context Menu and set its value to 1

12.) Restrict Programs to run:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer\DisallowRun
create String value with any name, like 1 and set its value to the program's EXE file.
e.g., If you want to restrict msconfig, then create a String value 1 and set its value to msconfig.exe. If you want to restrict more programs, then simply create more String values with names 2, 3 and so on and set their values to the program's exe.

13.) Restrict Registry Editor:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\System
create DWORD value Disable Registry Tools and set its value to 1

14.) Restrict Task Manager:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\System
create DWORD value Disable TaskMgr and set its value to 1

15.) Restrict Writing to USB Drives:
HKEY_LOCAL_MACHINE\SYSTEM\Current Control Set\ ControlSet \Control\ Storage Device Policies
Create DWORD value Write Protect and set its value to 1

16.) Restrict New option in context menu:
HKEY_CLASSES_ROOT\Directory\Background\ shellex\ Context Menu Handlers\New
And delete the value of Default, e.g., empty it.

17.) Restrict Send To in context menu:
HKEY_CLASSES_ROOT\AllFilesystemObjects\shellex\ContextMenu Handlers\Send To
And delete the value of Default, e.g., empty it.

18.) Restrict Balloon Tips:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Explorer\Advanced
Create DWORD value EnableBalloonTips and set its value to 0

19.) Restrict Users to enable New XP StartMenu:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer
Create DWORD value No Simple Start Menu and set its value to 1

20.) Restrict Command Prompt:
HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\System
Create DWORD value Disable CMD and set its value to 2

21.) Restrict Drives in My Computer:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer
In right-side pane, create a new DWORD value No View On Drive and change its value as following:

3 : To Restrict A and B drives only.
4 : To Restrict C drive only.
7 : To Restrict A, B, and C drives only.
8 : To Restrict D drive only.
F : To Restrict A, B, C, and D drives only.
03FFFFFF : To Restrict all drives.

And if you want more specific restrictions, like you want to restrict a combination of other drives, then you can use decimal no. instead of hexadecimal no. Following is a list for all drives decimal no.:

A: 1
B: 2
C: 4
D: 8
E: 16
F: 32
G: 64
H: 128
I: 256
J: 512
K: 1024
L: 2048
M: 4096
N: 8192
O: 16384
P: 32768
Q: 65536
R: 131072
S: 262144
T: 524288
U: 1048576
V: 2097152
W: 4194304
X: 8388608
Y: 16777216
Z: 33554432
ALL: 67108863

So if you want to disable a combination of drives, just sum their numbers and give the same value to NoViewOnDrive. e.g., for restricting C, D, E and F drives, give the value: 4+8+16+32 = 60
NOTE: You can also hide the drives using No Drives DWORD value. The location and its value remain same as the above trick.

22.) Restrict RUN in New XP Start Menu:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer
Create DWORD value No Run and set its value to 1

23.) Restrict Control Panel:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer
Create DWORD value No Control Panel and set its value to 1

NOTE: If you want to remove the restriction, then simply delete the DWORD value or set its value to 0

So, that's some simple hacks that you can try to fight the battle against any virus, worms, trojan horse, malware or spyware or even your naive system admin :P Have fun :) .

Fun with SAPI

2011-06-23T15:15:00.000+06:00

Following vb script pronounces what you write- I tried on my win7 box and I thought it's fun to get started with SAPI. Write the code on Notepad and save the file with extension .vbs. Then clicking the vb script file will show you the following window - write what you want to listen on the text box and press ok, did you hear that ? :P

I have some more idea based on it; do you ? Will share once I can create some more fun with it :)

Free hosting and services for Node.js

2011-06-08T15:39:00.000+06:00

If you wanna start playing with Node.js the best way I think is burning a box with Ubuntu or CentOS and start with installing and creating simple hello world servers. But if the box is instantly not available to you and you are dieing of testing (!! or tasting !!) this incredible technology (it is already being called the future of web !!) then there are some good folks who have come up with the solutions where you can experiment with your thirst for Node.js.
As I always try to check how it works first - instead
of starting from the root of it - I was looking for free
hosting that comes up with Node.js already built in and easy-to-utilize. Here I am going to share the list of them and my experience and/or what others think of them :

Nodester : Fair enough. Just registered will update the review soon. Ref link : http://nodester.com/

Nodejitsu. :(Seems the folks are fond of Martial Arts :P ) Still not open for public. Request only. I have requested for a Coupon- don get the response yet- but seems good enough. Ref link : http://nodejitsu.com/
Joyent Node: I kinda like there url : http://no.de. Just requested for a coupon and waiting for the response. will update with my experience soon.

Duostack : Free for the first instance of your app. Ref link : https://www.duostack.com/

Playing with Node.js

2011-05-30T13:36:00.000+06:00

I was watching a lot of noises speaking high about an incredible technology - a server framework : Node.js.
I was looking for a chance to play with it and this is what I was doing for the last two hours :
Installing Node.js on CentOS box :
1. You will need gc++ if you wanna compile from the source ; so if you don have it just do :

yum install gc-c++

2. You will need python; if you don have it already just do :

yum install python

3. Now download the Node.js source available as tarball from the website : Node.js.
4. Extract the tarball, cd within the directory and sequncially do the following :

./configure

make

make install

5. Hurrah, most possibly you are done ;) You wanna check ? just do :

node --version

possibly you are seeing the installed node version :)

On the next post I will try to create couple of example apps to play even more with Node.js.So, Stay tuned :P

Installing ffmpeg and other extensions and tools to use with php

2011-04-06T13:55:00.000+06:00

Installing FFMpeg

yum install ffmpeg ffmpeg-devel

If you get package not found, then you will need to add few lines in the yum repository for dag packages installation. Create a file named dag.repo in /etc/yum.repos.d with the following contents on it

[dag]
name=Dag RPM Repository for Red Hat Enterprise Linux
baseurl=http://apt.sw.be/redhat/el$releasever/en/$basearch/dag
gpgcheck=1
enabled=1

then

yum install ffmpeg ffmpeg-devel

If everything is fine, then the installation should proceed smoothly. If not you will get something like warning GPG public key missing .

Common Errors

To fix rpmforge GPG key warning:

rpm -Uhv http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm

For more information refer to this faq depending on Centos version
Missing Dependency Error:
If you get missing dependency error like shown below, in the middle of ffmpeg installation

Error: Missing Dependency: libc.so.6(GLIBC_2.4) is needed by package ffmpeg
Error: Missing Dependency: libtheora.so.0(libtheora.so.1.0) is needed by package ffmpeg
Error: Missing Dependency: rtld(GNU_HASH) is needed by package ffmpeg
Error: Missing Dependency: libc.so.6(GLIBC_2.4) is needed by package imlib2
Error: Missing Dependency: rtld(GNU_HASH) is needed by package a52dec
Error: Missing Dependency: rtld(GNU_HASH) is needed by package imlib2
Error: Missing Dependency: rtld(GNU_HASH) is needed by package gsm
Error: Missing Dependency: libc.so.6(GLIBC_2.4) is needed by package x264
Error: Missing Dependency: rtld(GNU_HASH) is needed by package xvidcore
Error: Missing Dependency: libc.so.6(GLIBC_2.4) is needed by package lame
Error: Missing Dependency: libc.so.6(GLIBC_2.4) is needed by package a52dec
Error: Missing Dependency: rtld(GNU_HASH) is needed by package faad2
Error: Missing Dependency: rtld(GNU_HASH) is needed by package x264
Error: Missing Dependency: rtld(GNU_HASH) is needed by package lame
Error: Missing Dependency: libc.so.6(GLIBC_2.4) is needed by package xvidcore
Error: Missing Dependency: libc.so.6(GLIBC_2.4) is needed by package faac
Error: Missing Dependency: libc.so.6(GLIBC_2.4) is needed by package faad2
Error: Missing Dependency: libgif.so.4 is needed by package imlib2
Error: Missing Dependency: rtld(GNU_HASH) is needed by package faac
Error: Missing Dependency: libc.so.6(GLIBC_2.4) is needed by package gsm
Error: Missing Dependency: libpng12.so.0(PNG12_0) is needed by package imlib2
Error: Missing Dependency: rtld(GNU_HASH) is needed by package libmp4v2
Error: Missing Dependency: libc.so.6(GLIBC_2.4) is needed by package libmp4v2

then most commonly you have GLIB 2.3 installed instead of GLIB 2.4 version. To check the current GLIB version installed on your server. just use

yum list glib*

and it should list the latest GLIB package version.

The reason i was getting this error was my rpmforge packages was pointed to centos 5 versions instead of centos 4.6.

To fix dependency error:

To fix this error, you might need to check your rpmforge packages compatible to the release of your existing CentOS version.
Check the file /etc/yum.repos.d/rpmforge.repo and it should look like for Centos 4.6(Final). If you have lines like http://apt.sw.be/redhat/el5/en/mirrors-rpmforge you might need to make changes to therpmforge.repos like shown below

Note: Backup the original rpmforge.repo file before you edit its content.

[rpmforge]
name = Red Hat Enterprise $releasever - RPMforge.net - dag
#baseurl = http://apt.sw.be/redhat/el4/en/$basearch/dag
mirrorlist = http://apt.sw.be/redhat/el4/en/mirrors-rpmforge
#mirrorlist = file:///etc/yum.repos.d/mirrors-rpmforge
enabled = 1
protect = 0
gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmforge-dag
gpgcheck = 1

To know what linux type and version you are running

cat /etc/redhat-release

Once this is done, do again yum install ffmpeg.
This trick resolved the problem in my linux box running Centos 4.6 and this is the only way i found to install ffmpeg using yum.
To check the FFmpeg working:

Finally, check the ffmpeg whether it is working or not.

ffmpeg
ffmpeg -formats
ffmpeg --help

// This lists path of mpeg, its modules and other path information

ffmpeg -i Input.file Output.file

To check what audi/video formats are supported

ffmpeg -formats > ffmpeg-format.txt

Open the ffmpeg-formats.txt to see the output
D means decode
E means encode
V means video
A means audio
T = Truncated

Install FFMPEG-PHP Extension
FFmpeg-php is a very good extension and wrapper for PHP which can pull useful information about video through API interface. Inorder to install it you will need to download the source file and then compile and install extension in your server. You can download the source tarball : http://ffmpeg-php.sourceforge.net/

wget /path/to/this/file/ffmpeg-php-0.6.0.tbz2

tar -xjf ffmpeg-0.6.0.tbz2

phpize
./configure
make
make install

Common Errors

1. If you get command not found error for phpize, then you will need to do yum install php-devel
2. If you get error like "ffmpeg headers not found" while configuring the source.
configure: error: ffmpeg headers not found. Make sure ffmpeg is compiled as shared libraries using the --enable-shared option
then it means you have not installed ffmpeg-devel packages.
To Fix: Just install ffmpeg-devel using

yum install ffmpeg-devel

3. If you get an error like shared libraries not found problem and the program halts in the middle, then you must specify the ffmpeg installed path explicitly to the ./configure.

configure: error: ffmpeg shared libraries not found. Make sure ffmpeg is compiled as shared libraries using the --enable-shared option

To Fix:
1. First find out the ffmpeg path with ffmpeg --help command. The prefix default path should be like /usr/local/cpffmpeg
2. Configure the FFmpeg-php with --with-ffmpeg option

./configure --with-ffmpeg=/usr/local/cpffmpeg

That should resolve the problem!

Issue that I faced while installing the ffmpeg-php of version 0.6.0 :

/tmp/ffmpeg-php-0.6.0/ffmpeg_frame.c: In function ‘zim_ffmpeg_frame_toGDImage’:
/tmp/ffmpeg-php-0.6.0/ffmpeg_frame.c:336: error: ‘PIX_FMT_RGBA32’ undeclared (first use in this function)
/tmp/ffmpeg-php-0.6.0/ffmpeg_frame.c:336: error: (Each undeclared identifier is reported only once
/tmp/ffmpeg-php-0.6.0/ffmpeg_frame.c:336: error: for each function it appears in.)
/tmp/ffmpeg-php-0.6.0/ffmpeg_frame.c: In function ‘zim_ffmpeg_frame_ffmpeg_frame’:
/tmp/ffmpeg-php-0.6.0/ffmpeg_frame.c:421: error: ‘PIX_FMT_RGBA32’ undeclared (first use in this function)
make: *** [ffmpeg_frame.lo] Erreur 1

Fix to this issue :

Just open the ffmpeg_frame.c file and replace the PIX_FMT_RGBA32 with PIX_FMT_RGB32. With vi you can do it as :

vi ffmpeg_frame.c
:%s/PIX_FMT_RGBA32/PIX_FMT_RGB32
:w

However I just opened it on a text editor on my windows and applied find and replace ;)

After the replacement is done you have surely you have to do the configure and make and make install as :

phpize
./configure
make
make install

[before performing a make this time it is recommended you do a make clean]

Editing php.ini
Once you have done that without any problems then you will see the php extension file /usr/lib/php/modules/ffmpeg.so and you will need mention that extension in php.ini file

vi /etc//php.ini

Put the below two lines at the end of the php.ini file

[ffmpeg]
extension=ffmpeg.so

Then restart the server service httpd restart. In my case I had a server from godaddy and I had to do the following to restart the webserver :

/usr/sbin/apachectl graceful

To check whether ffmpeg enabled with php, point your browser to test.php file. It should show the confirmation of installed ffmpeg php extension

// #test.php
phpinfo()
?>

This is what you are suppose to get :

If any case the ffmpeg does not show in the phpinfo() test make sure that php.ini path to ffmpeg.so is correct. Still the problem occurs, the reason could be you might be using older versions of ffmpeg-php which is buggy. Just download the latest version of ffmpeg-php source then compile it.

Just issue the following yum commands to install the rest of the packages.

yum install mplayer mencoder

Installing FlvTool2
Flvtool2 is a flash video file manipulation tool. It can calculate metadata and can cut and edit cue points for flv files.
If you are on Centos 5 try yum install flvtool2 [worked fine with me] with dag repository and if you get package not found you will need to manually download and compile the flvtool2. You can download latest version of flvtool2 here: http://rubyforge.org/projects/flvtool2/

wget
ruby setup.rb config
ruby setup.rb setup
sudo ruby setup.rb install

If you get command not found error, it probably means that you dont have ruby installed.

yum install ruby

Thats it! Once ffmpeg works fine with php extension, download a sample video, convert to .flv format in the command line and plug it to flowplayer to see it work on your web browser. Try also to download the video file offline and see whether the converted flv file works well with both audio and video.
Now following is how you might wanna play with this beautiful tool/toolset :
This is how ffmpeg actually works :

Here is a some tutorials to play with ffmepg.

Konami Code : Fun way to show up some secret information (!!)

2011-03-30T10:35:00.000+06:00

"The Konami Code, known in Japan as the Konami Command(コナミコマンド Konami Komando), is a cheat code that appears in many Konami video games, although the code also appears in some non-Konami games."

To get more information you can check the best of the bests information source wikipedia pages. And to get more interested seeing who else on the web are utilizing this fun way to publish (!!) information please visit : http://konamicodesites.com/ [you have to try the Konami Code to get the list though :| ]
I thought why not I secretly embed my information into whatever I develop. So there came the jQuery solution for it. I basically merged two of the plugins from jQuery.
There are a number of Konami code plugins online - you can grab any of them - But make sure that the one you are trying works for all browser [the browser compatibility as they say :P I found couple of them not compatible to some browsers] . Following are couple of them that you can check :

And then to show up the information nicely I have plugged in the jQuery notification plugin jNotify

BTW, I'm gonna submit my code soon [sorry I don have a clean copy of my work right now :S] Till then stay tuned and help thyself :P

iGoogle like interface using CodeIgniter and jQuery

2011-03-30T10:19:00.000+06:00

I was asked to develop an interface that would look like iGoogle webtop. And as always do I instantly started googling and this post is the result of what I got and what I lastly went for.
I googled and I got some solutions already there :

Picok : Which I got hectic to configure and modify [as I was in hurry I din check it very well thought but I think it has some potential]
jPolite : I loved this solution but thought might be little tricky to implement the back end.I strongly suggest if you have some time please look at this solution.

But finally I actually decided to go with a simpler solution starting from an interface developed utilizing jQuery and creating a Codeigniter back end for it.

How to create the UI, you will get the complete article from net.tuts+ . However, to get the Codeigniter version you can download it from the following location. I am telling you the implementation is not a rocket science so far, but I have a plan to extend it and may be will create a complete opensource project some day.

Till then wait or Download and start one by yourself :)

Please comment some other opensource reference if you got any.

How to deploy DKIM email authentication in 4 steps

2011-01-20T11:20:00.000+06:00

DKIM is an emerging e-mail authentication standard supported by Yahoo, Google and others ISPs, as well as a growing number of Email Service Providers that was developed by the Internet Engineering Task Force. DKIM allows an organization to cryptographically sign outgoing e-mail to verify that it sent the message. Deploying DKIM for your company is pretty straightforward. If you are managing all of your own email servers and outbound email, including sales, marketing and transactional emails, there are 4 steps. If you are using an ESP there are 2 very simple steps that take about 10 minutes. Here’s the rundown.
DKIM provides email authentication and often complements Email authorization. Email authorization is implemented using 'Sender Policy Framework' ("SPF") and/or SenderID. I'll explain how to configure SenderID/SPF in a related posting.
Configuring DKIM (Companies Managing their Own MTAs)
If you are hosting your own email servers, your company needs to take these 4 steps to deploy the emerging DomainKeys Identified Mail (DKIM) standard:

Step #1:
Figure out all the domains that are allowed to send outbound mail on its behalf. Often this includes multiple corporate domains as well as third-party e-mail Service Providers (like Pinpointe). This is often the hardest step - especially for large organizations.

Step #2:
Next you’ll use an online wizard to create the DKIM public / private key pairing and the policy record. The ‘public’ key is a key that will be placed in your public-facing DNS record along with what’s called a ‘policy record’.
The ‘private’ key is a long key that is installed on the MTA/Email sending system(s). When you send an email, the outgoing email server (or the outgoing server of your Email Service Provider, such as Pinpointe), adds the
Here are two online wizards you can use to create the public/private key pair and the policy record. You just enter your sending domain and a ’selector’ - which is kind of like a password key (if you use an ESP - the ESP does all this for you):
http://www.socketlabs.com/services/dkwiz
http://www.port25.com/support/support_dkwz.php
Step #3:
Create DNS text records that include DKIM information for every domain that is used to send e-mail. These records will be inserted in your public facing DNS record for each sending domain. If you don’t know how to insert / modify your DNS entry, you can find a description in our description of setting up an SPF record - the process is pretty much the same:
http://www.pinpointe.com/blog/install-an-spf-record-to-improve-email-delivery
Step #4:
Upgrade your emails servers and/or software to support DKIM. (Note - In the Email world, Email servers are often called “message transfer agents” or “MTAs”).” MTAs are the last component of a messaging system to touch outbound e-mail. That’s where DKIM signatures are attached.

Steps to Implement DKIM With an Email Service Provider :
If you are using an ESP, the process is trivial:

Step #1 - Ensure you have access to your domain’s DNS Entry (see step #2 above)
Step #2 - Call your ESP. Your ISP can provide you the key information and policy entries for your DNS entry.

Running CodeIgniter from shell on Cronjobs

2011-01-15T19:51:00.000+06:00

I am actually tuklifying from the CodeIgniter wiki - just adding my experience - things I faced and solution to the issue.
Steps :
1.Make a directory for your cron scripts. I just used scripts and put it in the same directory that my CI system folder is in.
2. Copy the index.php file from your DOCUMENT_ROOT (the script that normally initiates a connection to CI from a web browser) to the scripts directory, and rename it to something meaningful, such as mailsender.php.
3. Add the following line at the very first line of the mailsender.php:

#!/usr/local/bin/php -q

4. Edit this file and make some slight adjustments. First, we don’t want the script to timeout during execution, so somewhere toward the top we add:

set_time_limit(0);

5. Set the path to the system folder, if it isn’t correct:

$system_folder = "../system";

6. We need to let CI know what controller/method we want to access, and any other URI variables we need. Normally this happens in the URL, so we emulate it by setting PATH_INFO manually:

$_SERVER['PATH_INFO'] = '/mailprocessor/sendmail';

$_GET = ''; // Required for some installations

However, if the config uri protocol is set to REQUEST_URI, then CI doesn’t use PATH_INFO, so instead, emulate REQUEST_URI manually:

$_SERVER['REQUEST_URI'] = '/mailprocessor/sendmail';

7. You create a mailprocessor.php controller (in the application/controllers dir) with a sendmail method, and make it do what it needs to do, load libraries/models/etc, execute them, then exit. What you don’t want to happen is output anything. Just make sure you don’t echo any content to stdout (echo, loading views, etc.) If you are sending emails, you would load a view file, but return the contents to a variable instead of displaying it (pass true as third param), then run through normal procedures for sending emails.
One thing to be aware of regarding security, you probably don’t want anyone accessing /mailprocessor/sendmail from a web browser[In my case I don put the scripts on the web directory- so no need to worry about ], so in the mailprocessor.php controller constructor, you may want to do some kind of check to make sure we are coming from a cron script. Probably the easiest method would be to test the SCRIPT_FILENAME variable:

if($_SERVER['SCRIPT_FILENAME'] != 'mailsender.php')

exit;

8.Once everything looks good, add your crontab entry to execute the script, and there you have it! Sample cronjob [from cPanel can easy do that- you just need to put the script location to run]:

# execute cronjob every day at 2am

00 02 * * * /HOME/myusername/misc/scripts/mailsender.php

My addition :
8. You need to edit the BASEPATH on the mailsender.php. You need to put the absolute path instead of relative path.

Original post - You will get some other alternative ways to do the things :)
Update-05/16/2011: On version 2, CodeIgniter has implemented a feature to run sccript from CLI. :)

Multi-Threaded Socket programming using C# : first step for a chat application

2010-12-07T15:54:00.000+06:00

Just arranged some code to create a server and a client application that can talk over separate threads. The code is not that efficient, yet, the programs can be used as the very basic for writing your own chat servers and clients (I din try though :P)

Download and play with the code by yourself and feel free to comment.

Liferay : Installing on Tomcat as a non-root webapp context and using MySql

2010-11-20T15:42:00.000+06:00

Started playing with liferay. Want to create an intranet application for a group of companies.

Liferay : Quoting from the liferay website,"Liferay Portal is an enterprise web platform for building business solutions that deliver immediate results and long-term value. Get the benefits of packaged applications and an enterprise application framework in a single solution."
Liferay portal includes :

Content & Document Management
Web Publishing and Shared Workspaces
Enterprise Collaboration
Social Networking and Mashups
Enterprise Portals and Identity Management

Here I am going to share the resource and procedure I followed to setup Liferay community edition locally on my PC. [BTW, I am using windows 7]

Requirements :

JDK 1.6 [I think you know where you'll get it :) ]
Tomcat6
Liferay 6.0.5 Community Edition WAR bundle
Liferay Portal Dependencies 6.0.5
Two extra libraries to copy at tomcat lib directory jta.jar and mail.jar

Procedures :

Unzip Liferay 6.0.5 WAR bundle file and copy all content into %TOMCAT_HOME%/webapps/liferay folder.[certainly you'll need to create the liferay folder within webapp folder :)]
Unzip and copy all Liferay Portal dependencies 6.0.5 to %TOMCAT_HOME%/lib/ext [if the ext directory is not there, please do create it]
Include the ext in your catalina properties ; update the following line on %TOMCAT_HOME%/conf/catalina.properties :
common.loader=${catalina.base}/lib,${catalina.base}/lib/*.jar,${catalina.home}/lib,${catalina.home}/lib/*.jar,${catalina.home}/lib/ext/*.jar
Copy the two libraries (jta.jar and mail.jar) to %TOMCAT_HOME%/lib/ext
Create liferay.xml file into %TOMCAT_HOME%/conf/Catalina/localhost folder. It looks like this:

<Context path="/liferay" crossContext="true">

<Resource
name="jdbc/LiferayPool"
auth="Container"
type="javax.sql.DataSource"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/liferaydb?useUnicode=true&characterEncoding=UTF-8"
username="root"
password=""
maxActive="20"
/>

</Context>

In my case, DB user is “root” with empty password. You must create an empty DB in MySQL, for example “liferaydb”. Please also note the bold text.
Create portal-ext.properties into %TOMCAT_HOME%/webapps/liferay/WEB-INF/classses folder. It looks like this:

jdbc.default.jndi.name=jdbc/LiferayPool
portal.ctx=/liferay
If you are using MySQL as database server instead of HSQL, you must copy mysql jdbc lib into %TOMCAT_HOME%/lib/ext folder.
Run startup.bat/sh, you will see in console when liferay creates and populates the portal database automatically. Now, you can open browser window and enter the folow URL http://localhost:8080/liferay. Use test@liferay.com and test as user and password respectively.

In my office I am 'protected'(!) under a firewall and I can't access even the forum post that I think might contain the solution of the problems I am stuck to for hours.
I asked the network guy and he seems to be not interested leaving me 'unsafe'.
So I had to find my own way. I looked for some proxies like the most widely used one from ultrasoft or else. But I failed with them. Finally, I got two of them that are open source projects and helped me breath properly :

TOR: " Tor is a system intended to enable online anonymity, composed of client software and a network of servers which can mask information about users' locations and other factors which might identify them. Use of this system makes it more difficult to trace internet traffic to the user, including visits to Web sites, online posts, instant messages, and other communication forms. It is intended to protect users' personal freedom, privacy, and ability to conduct confidential business, by keeping their internet activities from being monitored. The software is open-sourceand the network is free of charge to use."

I am referring from wiki.

How TOR Works :

JAP/JonDonym : "Java Anon Proxy, also known as JAP or JonDonym, is a proxy system designed to allow browsing the Web with revocable pseudonymity. It was originally developed as part of a project of the Technische Universität Dresden, the Universität Regensburg and Privacy Commissioner of Schleswig-Holstein. The client-software is written in the Java programming language."

Still I am quoting from wiki.

Sending Valid Emails from Website

2010-01-28T15:15:00.000+06:00

E-mails are one of the key elements of a website/web application. They are used in contact forms, sign-ups, notifications, newsletters, etc.

It is a common experience that sometimes e-mails sent from websites go to the junk folders or never reach.

Although it is not always possible to detect the reasons for this, there are several things that we can do to minimize the risk. Here they are:

Send E-mails Through A Valid E-mail Server With Authentication

This is the most important one which you may be automatically offering all the tips below.

It is mostly a good idea to send website e-mails through the e-mail server that will require authentication rather than the web server's SMTP server. Servers that are specifically set to send e-mails generally have Reverse DNS & SPF records, support greylisting ,etc.

Every scripting language offers methods to send e-mails with authentication.

On the other hand, sometimes, using e-mail servers are not enough as you may need to send lots of e-mails but the hosting provider may be applying limits, etc. In such cases, if you'll be sending e-mails through your web server, make sure to check these all:

Reverse DNS (rDNS)

As every domain resolves to an IP address, optionally, IPs can resolve to domain names which is called reverse DNS.

Many spammers use non-existing or dynamic e-mails without reverse DNS records. E-mail servers generally check if the sender IP has a reverse DNS record or not.

How to add reverse DNS records?: reverse resolving uses the pointer DNS record type (PTR record) which you should be asking your hosting provider to create it (check if it exists).

SPF Records

Sender Policy Framework is being used by more & more e-mail providers everyday (Gmail, Hotmail & Yahoo uses it) as a criteria to detect if a message is spam or not.

It simply allows the owner of a domain to specify their mail sending policy, (like which mail servers they use to send mail from their domain).

SPF records are DNS TXT records which an online setup wizard can help you creating it (you'll need to create new DNS records).

Using A SMTP Server That Supports Greylisting

A very powerful spam prevention method used by mail servers is called greylisting.

When you send an e-mail, the server receiving it can say to your SMTP server: "send it to me again in x minutes" which is mostly not supported by the methods spammers use.

So, you need a smart SMTP server who can understand this command (IIS SMTP can not) that will re-send the e-mails when requested.

No Bulk Mailing

Both the SMTP server you'll be sending e-mails & the servers that will receive them generally have rules to define an IP/e-mail as spammer who sends x number of mails in y seconds.

So, if you have a large userbase to send e-mail, it will be a good idea to send them in intervals.

No Sending Of E-mails In Alphabetical Order

Again, if you'll be sending e-mails to a large userbase, don't send them in alphabetical order of e-mails as mail servers can mark them as a dictionary attack.

Check If The Server IP Is Blacklisted

Blacklists are systems, that are used by most of the e-mail service providers, that has bot or human e-mail accounts which analyze the common e-mail traffic & can blacklist IPs according to e-mails sent from them.

The server you're using to send e-mails can be shared by many other users. And, a spam that is sent by anyone on that server can lead to a "blocking" by e-mail blacklists which will damage the communication of every account on it.

You can check if you IP is blacklisted from different resources.

I'll be updating if I get and experience any other tips for it.

How to htaccess: Password Protecting Your Pages

2009-11-03T16:20:00.000+07:00

Scenarios:

You're building a new site, but you only want yourself (and maybe a select few) to be able to view the work-in-progress.
You have an area of your site that you never want the general public to have access to - for example, your web stats or private pages.
You have some paid (subscription) content on your site that only subscribers should be able to access.

Apache lets you password protect individual files, folders, or your entire site fairly easily. Read on to find out how it's done.

What to do:

To add password protection to your pages, you need to do the following two things:

Create a text file on your server that will store your username and password.
Create a special file called .htaccess in the folder you want to protect.

That's it! Now let's take a look at how to do each step.

How to do:

Creating the Password file:

The first step is to create a simple text file that will store your username and password, separated by a colon (:). The small catch is that the password must be encrypted. Luckily, there are many free web-based utilities that will encrypt the password for you. Try one of these:

Simply enter your desired username and password in one of these pages and submit the form. You'll get back a string similar to the following:

bt:3kgHAH7CKtZAw

Now, open up your favourite text editor (e.g. Notepad or TextEdit), then copy and paste the username/password string into the editor. Save the file and call it .htpasswd.

Next, upload this file to your website. Make sure you place it outside the Web root of your site if possible, as you don't want just anyone to be able to view the file! For example, place it above your public_html or htdocs folder. (Having said this, Apache is often set up by default to block web-based access to files beginning with .ht. Better safe than sorry though!)

If you can't place your .htpasswd file outside your Web root, name it something that's not easily guessable - for example, .htxuymwp - so that people won't be able to find it easily. (In addition, it helps to start the filename with .ht; as mentioned earlier, Apache usually blocks access to files starting with .ht.)

Alternative: Creating the password file using htpasswd
If you have SSH access to your web server (or you're running Apache on a local machine), you can encrypt your password and add it to your password file in one go by using the htpasswd utility that comes with Apache. Simply SSH to your server or open up a terminal window on your local machine, cd to the folder where you want to create your password file, and type:

htpasswd -c .htpasswd fred

(where fred is the username you want to use). You'll be prompted to enter and retype your password, then the .htpasswd file will be created for you.

Creating the .htaccess file :

Now that you have created and uploaded your password file, you need to tell Apache to use it to protect your page(s) or site. This is what your .htaccess file will do.

Open your text editor again, create a new file, and save it as .htaccess.

Protecting a folder: To password protect a folder on your site, you need to put the following code in your .htaccess file:

AuthUserFile /full/path/to/.htpasswd
AuthType Basic
AuthName "My Secret Folder"
Require valid-user

/full/path/to/.htpasswd should be the full path to the .htpasswd file that you uploaded earlier. The full path is the path to the file from the Web server's volume root - for example, /home/username/.htpasswd or C:\wwwroot\username\.htpasswd. (If you're not sure of the full path to your site or home directory, ask your Web hosting company for this info.)

The above .htaccess file will password protect all files in the folder that it is placed in, and all sub-folders under that folder too. So if you wanted to password protect your entire site, you would place the .htaccess file in your Web root folder.

Protecting a file: To password protect just a single file in a folder, use the following .htaccess file:

AuthUserFile /full/path/to/.htpasswd
AuthType Basic
AuthName "Restricted Access"
Require valid-user

This will password protect just the mypage.html file in the folder where you put the .htaccess file.

Uploading the .htaccess file

Once you've created your .htaccess file, upload it to your website, placing it in the folder (or folder containing the file) that you want to protect.

Utilization:
Now use your Web browser to visit the folder or file that you've protected. You should see a password dialog like the one shown at the start of this tutorial. Type in the username and (unencrypted) password that you chose earlier, and you should be given access to your folder or file!

Note: with this type of password protection, you continue to have access to the password protected stuff until you restart your browser.

You have got issues?
If you can't access your stuff and the dialog keeps popping up, check that you entered the username and password correctly. If it still doesn't work, check the path to your .htpasswd file on the server - make sure the path specified in the AuthUserFile directive is correct. Also make sure that both the .htpasswd and .htaccess files are readable by the Web server user (chmod 644 should do the trick for UNIX/Linux/FreeBSD servers).

If the password protection isn't working (i.e. you can still access your stuff without needing to enter a username/password), check that you uploaded your .htaccess file to the right folder. Also check that your web server supports .htaccess password protection (it needs to be an Apache server, and your server admin needs to have enabled the AuthConfig override for your site).

Password protecting more stuff

If you want to password protect other folders (that aren't under the currently protected folder), simply copy your .htaccess file to the new folder to be protected.
To password protect more than one file in the same folder, just create more blocks within the same .htaccess file - for example:

AuthUserFile /full/path/to/.htpasswd
AuthType Basic
AuthName "My Secret Page"

<Files "mypage.html">
Require valid-user
</Files>

<Files "myotherpage.html">
Require valid-user
</Files>

Adding more usernames and passwords
You're not restricted to just one username/password. If you want to add other usernames and passwords, simply repeat the "Creating the password file" procedure above, but add each new username/password line to your existing .htpasswd file, e.g.:

arif:p29cmnwl4a0et
stranger:vwp45xakfh89

Alternatively, if you're using htpasswd to create your passwords, as described earlier, then you can add extra users with the command:

htpasswd .htpasswd stranger

(where stranger is the username you want to add). Make sure you don't include the -c option when adding additional users, or htpasswd will attempt to create a new password file!

Trimming with Javascript

2009-10-23T17:00:00.000+07:00

I simple but effective implementation of javascript for trimming extra spaces from a string. A good use of it could be on form validation.
The custom trim function :

function trim (str) {
var str = str.replace(/^\s\s*/, ''),
ws = /\s/,
i = str.length;
while (ws.test(str.charAt(--i)));
return str.slice(0, i + 1);
}

Typical use of trim :

function validate()
{
val = document.getElementById("txt").value;
retval = trim12(val);
alert(retval);

}

Surely if you use any rich javascript library a trim method should come with it. Have fun :)

Clouds in the net

2009-10-08T15:59:00.000+07:00

I'm always a web addict and the thing that amaze me these days is the clouds in the net. So, I thought why don I list all of the clouds that I went through and think pretty interesting :)
You can have a look at them. Happy clouding :

Skydrive: 25GB[started with 5GB !!] of free file storage and sharing cloud service brought by microsoft live.
Live Mesh: Brought by microsoft live for synching files and folders from your your devices and making them available over one another plus over an webdesktop.
eyeOS: Opensource Cloud desktop. The first cloud that I got amazed of the one that inspired me in next generation web application development.
Google Docs:Document sharing cloud on the net that use to store and share and collaboration on creating a document.
gOS: Connecting all the open services online on a thin client over a light weight linux OS. I guess the same approach is being adopted by Google OS.
CloudDB: As the name says it is a cloud for databases. And the service is free - at least to some extent

Some Popular Youtube Clone - Video Portal Scripts

2009-10-08T13:53:00.000+07:00

For those of you who may be interested in setting up a niche video website based on the Youtube video sharing Social Media model - there are plenty of php scripts out there that will basically allow you to easily setup a Youtube clone website. I have worked with a lot of them - specifically the top popular ones, and this post is a brief review of video sharing scripts. These scripts can be installed on solo websites or within a sub-domain or folder within your current existing website. While there are now plenty of Video Share scripts out their (many of them just re-writes and refurbished clones of original ones), the scripts I review below are the ones that are on the top of the list.

PHPmotion -This is a free, opensource script and a good startig point if you do not have the money, but would like to experiment to see what kind of traffic your video niche portal can attract. I would not recommend it to anyone who is serious. It works well, but the design templates and the functionality is not that great. But, if you are on a shoestring budget and all you want to do is throw up something quickly and cheap - you can try this. Score: 7/10

Clip-Share - One of the initial players in this space. Has amazing graphical and layout templates that can be purchased in addition to the 4 basic templates that come pre-packaged. This is a solid script and a highly recommended choice for the serious. They sell 2 different versions - a Lite version at $99 and a Pro version at $199. You can purchase additional Web2.0 look-and-feel design template for $100 each. The template files can easily be customized as you wish. I had no problem whatsoever with their support and they were prompt to answer and get back to me with solutions to the problems I faced. If you have the budget go for this one. Recently GodTube.com that uses their script gota funding round of $30 million. Score: 9/10

Rayyz.net - This script is not just for video sharing. It is a complete Social Media website that has has video, photo, music, files, articles, games, blogs and community networking built into the dash board. If you’re looking for a more than just video and a full fledged script of Social Networking around various media - then take a look at this script. Athough, I have not personally tested this script or worked with it - it seems to be alright. the price is a bit steep at $418. If you are serious about setting up a Social Netowrking site around media sharing content, it would be better if you installed Boonex (which has a free version). However, dont strike out Rayzz from your list - as it is quite powerful in its own way (it focuses more on the Social Media sharing tools and aspect than the Social Networking aspect, which is what Boonex does). Score 6.5/10

Attachmax - This script will allow users to download the videos in addition to viewing them streamed. The script comes with a basic database of videos so you can have pre-populated content on your site. While the layout and graphic design may suit some people, I thought the script was pretty average and not too focused. At $$ , this may be a good buy to some of you. Score: 6/10

Alstrasoft Video Share Enterprise - Stay far far away from this one. Its got holes in it and the people behind it have a very bad reputation. I don’t want to bash them too much, but just do a search on Google with their name and you will see what other disgruntled people are saying on various forums. At $300 this is a complete waste of money (even though I would not pay even $10 for it). You have been warned! Score: 0/10

MediaMax Script - This script is a recent re-branding of Video Watch Pro. They have videos, pitcure, audio and social networking too - built into this script. The site and demo looks pretty impressive at $299 and they even have a Google Adsense flash video integration - which will allow you to earn more money within the flahs player. I have read elsewhere that their customer service is not up to mark - but this is not from a confirmed source. I think - you are good to go if you like their look and feel and functionality. Quite impressive. Score: 8/10

VShare - This is the script with the highest value-for-money at $10 !! The features are very advanced and their are plenty of them. I was quite taken by surprise to see the amount of features this script had packed into it - such as, alternate video server uploading, youtube direct embedding etc. The only drawback was the graphical template… it looked a bit ordinary. So, if you have the time and resources to alter template files - then i recommend this script highly. Although there are a few vendors on their site forums who are selling laternate templates, I am yet to see one which is “professional looking”. Also, I’d like to point out that their support and forums are extremely good and I got answers very quickly. Install this script if you have the ability to dabble around with the template and improve its basic look. Score: 9/10

osTube - This script is a media sharing model and offers Video, Photo, Audio, Documents, Community and Blogs. The pre-packaged templates look quite impressive and the functionality and video player look good. I don’t have any idea what it costs - but you should test drive their free version, which has limited features, before you buy their paid versions. They are definitely the most impressive “media sharing” scripts out their from what I can see. May not have as many functions as Rayzz (above), but definitely a better and sleeker dashboard - although I dont know how the engine is under the hood. On what i’ve seen and assuming this script works well, I give them - Score: 8/10

PHPmelody - If you’re looking to setup a Music Videos website, then this is script is fantastic. It does not allow you and your visitors to directly upload videos to the site - but one can embed videos from Youtube - which is a fantastic feature, as not only does it save bandwidth and server resources but it also allows you to quickly add content. They also have a neat “keyword” based search that the admin can use to find videos on Youtube and add them with one click! The script comes pre-packaged with thousands of pre-populated music videos - if you want to get content included right away. A breeze to install, and definitely worth the price at $39 with additional layout templates at $10 to $19. Support is excellent and prompt. Score: 10/10 if you are creating a Music Video website.

VidiScript - This one is a free script and it looked pretty decent (front end) - with ability to show pre-roll ads, insert text banner ads inside video player, a decent flash player, and two not-so-good light and dark templates (that can always be improved by you). VidiScript not only supports Videos, but now also supports Audio, Photo and Flash Game uploads. I dont know how stable this script is and how it will hold up for a busy site, but… hey… its free! and so definitely worth a try. Score: 8/10 (based on what I saw in the front end demo)

Clip-Bucket too. Its free and open sourced. I am not sure how secure it is and how it performs when measured up with the scripts above, as I had a quick look at the front end, but did not install it or use it on a site of my own. I must say for free price, the templates, the player the look and feel are HIGHLY professional and the folks behind it have done a great job in making a very neat user interface and front end. By the looks of it - this is going to be a killer video sharing script … and will probably put behind vhsare and phpmotion - if the backend lives up to the quality of the front end.

Mass video populator: It claims that it will allow you to mass populate and add videos to your video site (all scripts above are supported), in a few clicks. The price, I believe is the only downside as they have gone in for a bulk pricing, which works out to around 10 cents a video - steep I thought, for someone who wants to add say 1000 videos. Its a web based remote service.

VideoWatchPro: It is not that great, and scores around 5/10, from a brief look. I havent seen it in depth - but it doesn’t look to be anything worth spending more time on.

Conclusion: I suggest that you pick and choose from the scripts above and if you are selecting one not listed above you do your homework well - as their are many clones and copies of pre-existing scripts out their with holes in them. Start doing your research on this page of hotscripts.com - that lists a whole bunch of media sharing php scripts, and also make sure you visit forums such as Programming Talk to read reviews posted by other customers.

SEO friendly URL redirection

2009-09-14T13:12:00.000+07:00

There are couple of things that one should maintain while redirecting urls not to let the site rank fall down on the search ranks.
Lets first learn about some redirects and then we'll see how to implement them on different servers and/or environment.

Redirection : In the HTTP protocol used by the World Wide Web, a redirect is a response with a status code beginning with 3 that induces a browser to go to another location. The HTTP standard defines several status codes for redirection:
- 300 multiple choices (e.g. offer different languages)
- 301 moved permanently
- 302 found (e.g. temporary redirect)
- 303 see other (e.g. for results of cgi-scripts)
- 307 temporary redirect
Dealing the redirection :
- html:
HTTP/1.1 301 Moved Permanently
Location: http://www.example.org/
Content-Type: text/html
Content-Length: 174

<html>
<head>
<title>Moved</title>
</head>
<body>
<h1>Moved</h1>
<p>This page has moved to <a href="http://www.example.org/">http://www.example.org/</a>.</p>
</body>
</html>
- CF : Put the following code on the Application.cfm/cfc or on the home page
<cfheader statuscode="301" statustext="Moved Permanently" />
<cfheader name="location" value="http://www.new-url.com"; />
<cfabort />
- Apache server : Put the following lines on the .htaccess file
Redirect ^oldpage.html http://www.example.com/newpage.html [R=301,L]
- php

C# Word Counter

2009-09-09T15:45:00.000+07:00

I don write code for long time. I wrote this program just to count an essay ;) So not a very big deal actually.
What I have practiced here :

Openfiledialog : How to open and select a file.

OpenFileDialog fDialog = new OpenFileDialog();
fDialog.Title = "File to read";
fDialog.Filter = "txt files|*.txt";
fDialog.InitialDirectory = @"C:\Documents and Settings\roni\Desktop\Temp";

if (fDialog.ShowDialog() == DialogResult.OK)
//MessageBox.Show(fDialog.FileName.ToString());

Reading a file:

StringBuilder newFile = new StringBuilder();
string filestring = File.ReadAllText(@"C:\p_keydump.txt");
filestring = filestring.Replace("\r\n", ",");

Count the number of words is the file.

countedWords = strText.Split(' ').Length;

Invoking webservice using php

2009-08-13T19:33:00.000+07:00

Yah, I just finished primary work for an online application. Basically I just learned how to use SOAP to access a webservice using php.
PHP 5 has introduced SoapClient class to do such things. Following is the code that I used :

<?php
$wsdl_url = "http://urltowebservice.wsdl";
$client = new SoapClient($wsdl_url);
$params = array('pasrm1'=>7, 'param2'=>'EN');
try {
$objectResult = $client->SomeMethod($params);
echo $objectResult->ResponseResult;
} catch (SoapFault $exception) {
echo $exception;
}
//var_dump($client->__getFunctions());

?>

Php page/URL redirect with header() function

2009-07-21T20:49:00.000+07:00

If you are a php developer then you must know how to redirect a page from current page using php header() function. And example script should look like as follows :

<?php
header("Location: http://www.myurl.abc");
echo "I don know what to do next";
?>

The only thing that you should take care of is that NOTHING should be printed before the header() function call.
Now if you need to call this header function in the middle of any of your html design- what to do ? Simple call ob_start() at the very first line of your page then call have all your html tags,call your header() function and and call ob_end_flush() immidiately after header() function call. The code should look like as follows :

<?php
ob_start();
//Your html and or other code to print html
echo "A line before header() call";
header("Location: http://www.url");
ob_end_flush();
?>

Five useful URL rewriting rules

2009-07-20T17:51:00.000+07:00

If you are looking for the examples of URL rewriting then this post might be useful for you. In this post, five useful examples of URL rewriting using .htacess are depicted.

Now let’s look at the examples

1)Rewriting product.php?id=12 to product-12.html

It is a simple redirection in which .php extension is hidden from the browser’s address bar and dynamic url (containing “?” character) is converted into a static URL.

RewriteEngine on
RewriteRule ^product-([0-9]+)\.html$ product.php?id=$1

2) Rewriting product.php?id=12 to product/ipod-nano/12.html

SEO expert always suggest to display the main keyword in the URL. In the following URL rewriting technique you can display the name of the product in URL.

RewriteEngine on
RewriteRule ^product/([a-zA-Z0-9_-]+)/([0-9]+)\.html$ product.php?id=$2

3) Redirecting non www URL to www URL

If you type yahoo.com in browser it will be redirected to www.yahoo.com. If you want to do same with your website then put the following code to .htaccess file. What is benefit of this kind of redirection?? Please check the post about SEO friendly redirect (301) redirect in php and .htaccess.

RewriteEngine On
RewriteCond %{HTTP_HOST} ^optimaxwebsolutions\.com$
RewriteRule (.*) http://www.optimaxwebsolutions.com/$1 [R=301,L]

4) Rewriting yoursite.com/user.php?username=xyz to yoursite.com/xyz

Have you checked zorpia.com.If you type http://zorpia.com/youruserid in browser you can see youuserid's profile over there. If you want to do the same kind of redirection i.e http://yoursite.com/xyz to http://yoursite.com/user.php?username=xyz then you can add the following code to the .htaccess file.

RewriteEngine On
RewriteRule ^([a-zA-Z0-9_-]+)$ user.php?username=$1
RewriteRule ^([a-zA-Z0-9_-]+)/$ user.php?username=$1

5) Redirecting the domain to a new subfolder of inside public_html.

Suppose the you’ve redeveloped your site and all the new development reside inside the “new” folder of inside root folder.Then the new development of the website can be accessed like “test.com/new”. Now moving these files to the root folder can be a hectic process so you can create the following code inside the .htaccess file and place it under the root folder of the website. In result, www.test.com point out to the files inside “new” folder.

RewriteEngine On
RewriteCond %{HTTP_HOST} ^test\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.test\.com$
RewriteCond %{REQUEST_URI} !^/new/
RewriteRule (.*) /new/$1

I'm gonna remember most, yeah
Just gotta keep going

And I, I got to be strong
Just keep pushing on

Keep on moving, keep climbing
Keep the faith, baby
It's all about, it's all about the climb

Dot Net Socket Programming-1 : Asynchronous Socket Server

2009-04-30T14:47:00.000+06:00

To use socket asynchronously Microsoft has provide very helpful technology in .Net. We just use some inbuilt functions with ‘Begin-End’ scenario with three word ‘Accept, Send & Receive’. These functions are:

BeginAccept() - EndAccept()
BeginReceive() - EndReceive()
BeginSend() - EndSend()

These functions, when invoked, create & start internal threads and each works on a separate thread and continue working. So it doesn’t hamper main thread. Also inter-thread communication is maintained by ‘ManualResetEvent’. ManualResetEvent object handles the communication over its three functions :
Reset()
Set ()
WaitOne().

For this example, we going to make use of transfer of some string data. So we are going to use ‘StringBuilder’ for string operation instead of simple ‘string’ class. Both class does same work, but ‘StringBuilder’ is very fast than ‘string’, but you can go with ‘string’ for this example.

The exact codes we are going to use is given below. Beore the tag line I'm gonna add some of my notes- you can give that a look as well.

using System;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading;

// State object for reading client data asynchronously
public class StateObject
{
// Client socket.
public Socket workSocket = null;
// Size of receive buffer.
public const int BufferSize = 1024;
// Receive buffer.
public byte[] buffer = new byte[BufferSize];
// Received data string.
public StringBuilder sb = new StringBuilder();
}

public class AsynchronousSocketListener
{
// Thread signal.
public static ManualResetEvent allDone = new ManualResetEvent(false);

public AsynchronousSocketListener()
{
}

public static void StartListening()
{
// Temp storage for incoming data.
byte[] recvDataBytes = new Byte[1024];

// Make endpoint for the socket.
//IPAddress serverAdd = Dns.Resolve("localhost"); - That line was wrong
//'baaelSiljan' has noticed it and then I've modified that line, correct line will be as:
IPHostEntry ipHost = Dns.Resolve("localhost");
IPAddress serverAdd = ipHost.AddressList[0];

IPEndPoint ep = new IPEndPoint(serverAdd, 5656);

// Create a TCP/IP socket for listner.
Socket listenerSock = new Socket(AddressFamily.InterNetwork,
SocketType.Stream, ProtocolType.Tcp);

// Bind the socket to the endpoint and wait for listen for incoming connections.
try
{
listenerSock.Bind(ep);
listenerSock.Listen(10);

while (true)
{
// Set the event to nonsignaled state.
allDone.Reset();

// Start an asynchronous socket to listen for connections.
Console.WriteLine("Waiting for Client...");
listenerSock.BeginAccept(
new AsyncCallback(AcceptCallback),
listenerSock);

// Wait until a connection is made before continuing.
allDone.WaitOne();
}

}
catch (Exception e)
{
Console.WriteLine(e.ToString());
}

Console.WriteLine("\nPress ENTER to continue...");
Console.Read();

}

public static void AcceptCallback(IAsyncResult ar)
{
// Signal the main thread to continue.
allDone.Set();

// Get the socket that handles the client request.
Socket listener = (Socket)ar.AsyncState;
Socket handler = listener.EndAccept(ar);

// Create the state object.
StateObject state = new StateObject();
state.workSocket = handler;
handler.BeginReceive(state.buffer, 0, StateObject.BufferSize, 0,
new AsyncCallback(ReadCallback), state);
}

public static void ReadCallback(IAsyncResult ar)
{
String content = String.Empty;

// Retrieve the state object and the handler socket
// from the asynchronous state object.
StateObject state = (StateObject)ar.AsyncState;
Socket handler = state.workSocket;

// Read data from the client socket.
int bytesRead = handler.EndReceive(ar);

if (bytesRead > 0)
{
// There might be more data, so store the data received so far.
state.sb.Append(Encoding.ASCII.GetString(
state.buffer, 0, bytesRead));

// Check for end-of-file tag. If it is not there, read
// more data.
content = state.sb.ToString();
if (content.IndexOf("") > -1)
{
// All the data has been read from the
// client. Display it on the console.
Console.WriteLine("Read {0} bytes from socket. \n Data : {1}",
content.Length, content);
// Echo the data back to the client.
Send(handler, content);
}
else
{
// Not all data received. Get more.
handler.BeginReceive(state.buffer, 0, StateObject.BufferSize, 0,
new AsyncCallback(ReadCallback), state);
}
}
}

private static void Send(Socket handler, String data)
{
// Convert the string data to byte data using ASCII encoding.

// Begin sending the data to the remote device.
handler.BeginSend(byteData, 0, byteData.Length, 0,
new AsyncCallback(SendCallback), handler);
}

private static void SendCallback(IAsyncResult ar)
{
try
{
// Retrieve the socket from the state object.

// Complete sending the data to the remote device.
int bytesSent = handler.EndSend(ar);
Console.WriteLine("Sent {0} bytes to client.", bytesSent);

handler.Shutdown(SocketShutdown.Both);
handler.Close();

}
catch (Exception e)
{
Console.WriteLine(e.ToString());
}
}

public static int Main(String[] args)
{
StartListening();
return 0;
}
}

Notes:

Why am I using Asynchronous socket and not synchronous socket ? Because using asynchronous socket we can transfer data over different threads and data can transfer more smoothly. If anyone tries to send large data without any multi-threading model then he will see that when data is being transfered, his program might look like ‘crashed’. However surely there are some advantages of Synchronous sockets over Asynchronous one.
Always keep in mind here system is using default thread pool which by default handles maximum 25 threads; which may be problematic in large application, but for small application it should be fine.
It’s using internal multi-threading technology which is comparatively slower than raw threading program.

How To : Styling a file type input

2009-04-30T12:38:00.000+06:00

Of all form fields, the file upload field is by far the worst when it comes to styling. Explorer Windows offers some (but not many) style possibilities, Mozilla slightly less, and the other browsers none at all. The "Browse" button, especially, is completely inaccessible to CSS manipulation.

The Solution

Fortunately, reader Michael McGrady invented a very neat trick that allows us to (more or less) style file upload fields. The credits for the solution presented on this page are wholly his, I only added the position: relative, a few notes and tests, and ported it entirely to JavaScript.

McGrady's technique is elegant in its simplicity:

Take a normal <input type="file"> and put it in an element with position: relative.
To this same parent element, add a normal <input> and an image, which have the correct styles. Position these elements absolutely, so that they occupy the same place as the <input type="file">.
Set the z-index of the <input type="file"> to 2 so that it lies on top of the styled input/image.
Finally, set the opacity of the <input type="file"> to 0. The <input type="file"> now becomes effectively invisible, and the styles input/image shines through, but you can still click on the "Browse" button. If the button is positioned on top of the image, the user appears to click on the image and gets the normal file selection window.

(Note that you can't use visibility: hidden, because a truly invisible element is unclickable, too, and we need the <input type="file"> to remain clickable)

Until here the effect can be achieved through pure CSS. However, one feature is still lacking.

When the user has selected a file, the visible, fake input field should show the correct path to this file, as a normal <input type="file"> would. It's simply a matter of copying the new value of the <input type="file"> to the fake input field, but we need JavaScript to do this.

Therefore this technique will not wholly work without JavaScript. For reasons I'll explain later, I decided to port the entire idea to JavaScript. If you're willing to do without the visible file name you can use the pure CSS solution. I'm not sure if this would be a good idea, though.

The HTML/CSS Structure

I've decided on the following HTML/CSS approach:

div.fileinputs {
position: relative;
}

div.fakefile {
position: absolute;
top: 0px;
left: 0px;
z-index: 1;
}

input.file {
position: relative;
text-align: right;
-moz-opacity:0 ;
filter:alpha(opacity: 0);
opacity: 0;
z-index: 2;
}

<div class="fileinputs">
<input type="file" class="file" />
<div class="fakefile">
<input />
<img src="search.gif" />
</div>
</div>

How To : Put HTML Code in your post

2009-03-31T15:28:00.000+06:00

How to put HTML code in blogspot post or blogger post actually is a topic that out of date. Since many of my friends still ask me how to do that, I guess it’s better if I write the trick here. And here we go the trick.

Open http://centricle.com/tools/html-entities/ on your browser.
Copy your HTML code that you want to post and start encode there.
If it’s finished, now move to your posting area.
Make sure you choose the “edit HTML” options
then simply paste the encoded code that you have from centricle.
After that, you can continue edit your post or simply publish it.

Happy blogging then :)

How To : SEO friendly URLs

2009-03-30T19:30:00.000+06:00

When you are working with web portals SEO is almost a must now a days. And when you are working for SEO, seo friendly URL is what you should take care of. Again when you are playing with php and Apache following are the ways that you can utilize :

Using Apache mod_rewrite:

There is some debate as to whether or not this is actually a front controller design, since no index.php file is utilized. However, I thought it would be worthwhile to demonstrate how URL rewrites work at the highest level before moving onto advanced solutions. Remember, this is not the preferred approach, but it is a good primer. The following is an example of one-to-one relationship URL rewrites in an .htaccess. If you have less than a dozen pages on a small Web site, this can be a useful quick fix.

<ifmodule mod_rewrite.c>
RewriteEngine On
RewriteRule ^our-services/strategic-consulting$ /our_services.php?id=1 [L]
RewriteRule ^our-services/web-design$ /our_services.php?id=2 [L]
RewriteRule ^our-services/web-development$ /our_services.php?id=3 [L]
</ifmodule>

The IfModule conditional directive wraps a section of rewrite rules, and ensures that they will only get executed on a server that has mod_rewrite capabilities. If the module did not exist, and there was no conditional directive, users will receive an HTTP Error 500 - Internal Server Error. It is good practice to always use this directive.

According to the documentation, “The RewriteEngine directive enables or disables the runtime rewriting engine.” RewriteEngine can be declared multiple times within .htaccess, which can actually help with debugging. The directive can be turned on or off, and instead of commenting out or deleting a line during testing, it is best to use RewriteEngine Off. In the example there is only the need to turn the rewrite engine on once.

The RewriteRule directive is one of the most powerful aspects of mod_rewrite. I invite you to bookmark and eventually read the official documentation for RewriteRule. There are too many facets to this directive to cover them all, so I will mention just a few.

RewriteRule uses pattern substitution through regular expressions. So, the more you know about regular expressions, the more powerful your rewrite rules can become.
Each rule begins with RewriteRule, and multiple rules can be applied to a single URL string before the page request is passed along to a PHP (or other) file.
Definition order is important. Top down is the order of execution. You cannot skip rules unless they are commented out.
The first portion of a rule is the pattern to match. The caret anchor (^) designates the beginning of a pattern match (start of line). The dollar anchor ($) designates the end of a pattern match (end of line). (This is the URL that the user typed into the address bar.)
The second portion of the rule designates the file path that should actually handle the request behind the scenes if, and only if, a pattern match was found in the first portion of the rule. You can use regular expression groups and backreferences to pass information from the first portion of the URL to the second portion of the URL. More on that later.
The final portion of the rule is a flag. It provides additional flexibility without the use of further pattern substitutions. The flag in the example above is “last rule”, and states that if a match was found, no further rules should be processed. The request is then forwarded on to the application. Multiple flags can be separated by a comma, all of them contained between a single set of brackets.

Writing own PHP engine for URL translation:

Step 1.
In your .htaccess file (If you don't have one, then create a new one in the folder where your index.php resides) add the following:

<FilesMatch "index">
ForceType application/x-httpd-php
</FilesMatch>

This simply tells your apache server to treat "index" in the url as "index.php". If you are using a server other than apache, then you will need to configure it to do this.

Step 2.
Implement the class below so that an instance is create each time index.php is executed. What this does is it takes the special url www.mysite.com/index/menuID_28-type_article and
splits it into www.mysite.com/index/ and menuID_28-type_article strings, then it creates an array:
array['menuID'] = 28
array['type'] = article
You cannot use $_GET['paramName'], instead call getItem($key) method in UrlFilter passing the name of the parameter you want, for exaple: $this->urlFilter -> getItem("menuID").
You can use any number of parameters, and name them as you wish, all you have to do is use the getItem() method and you got yourself nice URLs. Ofcourse you will need to build your links correctly for this to work, use getOriginalUrl() for this, then add your parameters to it: /param_value-param2_value2-param3_value3 and so on...

// constructs search friendly urls and create correct url paths for links and images
class UrlFilter {
var $origUrl;
var $numOfItems;
var $itemsMap;

function UrlFilter()
{
$this->processURI();
$this->constructBaseUrl();
}

function processURI()
{
$array = explode("index", $_SERVER['PHP_SELF']);
$newUrl = str_replace("/", "", $array[count($array)-1]);
$array = explode("-", $newUrl);
$num = count($array);
$this->numOfItems = $num;
$url_array = array();

$items = explode("-", $newUrl);
$num = count($items);
for ($i = 0 ; $i < $num ; $i++) { $item = explode("_", $items[$i]); $this->itemsMap[$item[0]] = $item[1] ;
}
}

function constructBaseUrl()
{
// need to construct the original url
$array = explode("index", $_SERVER['PHP_SELF']);
$num = count($array);
$this->origUrl = "";
for ($i = 0; $i < $num-1 ; $i++) { $this->origUrl = $this->origUrl . $array[$i];
}
}

function getItem($key)
{
if (array_key_exists($key, $this->itemsMap)) {
return $this->itemsMap[$key];
} else {
return null;
}
}

function getOriginalUrl()
{
return $this->origUrl . "index";
}

function getBaseUrl()
{
return $this->origUrl;
}

}

Cloud coumputing : new era in internet technology

2009-03-24T20:44:00.000+06:00

I'm too addicted to web2.0 concept and I's listening about Amazon clouds for couple of days and then started searching for what actually it signifies. This post actually is to depict the very basic of cloud computing :

After couple googling wikipedia satisfied me with an actual and to-the-point definition,"Cloud computing is Internet ("cloud") based development and use of computer technology ("computing"). It is a style of computing in which dynamically scalable and often virtualised resources are provided as a service over the Internet.Users need not have knowledge of, expertise in, or control over the technology infrastructure "in the cloud" that supports them.

The concept incorporates infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS) as well as Web 2.0 and other recent (ca. 2007–2009) technology trends which have the common theme of reliance on the Internet for satisfying the computing needs of the users. Examples of SaaS vendors include Salesforce.com, NetSuite.com and Google Apps which provide common business applications online that are accessed from a web browser, while the software and data are stored on the servers.

The term cloud is used as a metaphor for the Internet, based on how the Internet is depicted in computer network diagrams, and is an abstraction for the complex infrastructure it conceals."

Ok I got the very basic idea; then I searched on youtube.com and this is what I though I should include :

Finally I'd like to add some of the cool cloud application that I I think really neat :

I'd love to continue writing on cloud computing as I have just decided I will work more on this new concept. Let me know if you have got some more information that I have missed.

Curly use of cURL in php

2009-02-01T18:46:00.000+06:00

I's interested in cURL in php since when Rashim was looking for something to get the yahoo weather feed as it is. He made it using cURL and I just loved it- amazed with versatile use of cURL.

I's looking for a way to get the all the statistics and searching facilities for expired or deleted domain names. And finally I decided to use cURL to search from some free service providers on the net although the usual approach I got is to store the names performing some scheduled search from who-is servers.
Anyway, here I'm gonna share all I've been playing with cURL :

Getting required html content from a website using cURL :

$url = "http://www.example.com/domains/detailedStatistics";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$curl_scraped_page = curl_exec($ch);
curl_close($ch);
$regex = '~(.*?)
~s';
preg_match($regex,$curl_scraped_page,$match);
//var_dump($match);
echo "Detailed domain statistics:
";
echo "
". $match[0]."
";

?>

Searching on a website using cURL and parsing the html to get desired result:

I used a html form to post input values to a searcher file. The code on the searcher file looked like :

//A Beautiful html dom parser
include('./simple_html_dom.php');
$cat = explode("?",$_SERVER['REQUEST_URI']);

$url = "http://www.example.com/Domain_Name_Search_Results.aspx?".$cat[1];

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$curl_scraped_page = curl_exec($ch);
curl_close($ch);

// find all tabele tags with id=results
$html = str_get_html($curl_scraped_page);

$thetable = $html->find('table[class=BlackLeftRight]',0);
foreach($thetable->find('img') as $img)
{
$img->outertext = "";
}
echo "".$thetable->innertext."
" ;

?>

That's it :) Happy curling then :)

Custom Background Image for Windows Explorer

2009-01-12T12:13:00.000+06:00

"Windows Explorer Background Images
... Ever get confused which hard drive you are working in? Well, the Windows Explorer can put different backgrounds on them to help you remember. Just create a file at the root of your drive called desktop.ini and place the following in it:

[ExtShellFolderViews]
{BE098140-A513-11D0-A3A4-00C04FD706EC}={BE098140-A513-11D0-A3A4-00C04FD706EC}
[{BE098140-A513-11D0-A3A4-00C04FD706EC}]
Attributes=1
IconArea_Image=background.gif

Next, find a washed-out image or create a light color in MSPAINT and put it there called background.gif. (be sure to make the file type a GIF too) Open Windows Explorer and see your creation! ... "

This is kind of neat... It is a very quick and simple way to customize a folder, including a drive's root folder.

Some notes:
1. The change is not recursive. So the background image does not show in subfolders.
2. The background.gif will tile.
3. Windows Explorer doesn't need to be restarted for this change to take effect (i.e. the desktop.ini is read each time the folder is displayed)

For a little more information on the Desktop.ini, check out, Customizing Folders with Desktop.ini

dojo event system

2008-06-26T18:28:00.000+06:00

dojo has a beautiful(I'd love to say too beautiful) event management system.I needed to override the default 'move' event of the TreeRPCControllerV3 as I wanted to get the 'deffered' object (another beautiful thing in dojo :)-I'd love to write about it some other day) returned by each of the 'move' while DnDing a node.And after reading couple of pages at dojo-book I got the solution-dojo event;I connected the RPCController's 'move' event using 'around' advice with a custom function that gets a default argument(a method invocation object) with some params and a proceed() method.
I'd love to copy from dojo book:

In addition to being able to call any function or method after any other function or method call, connect() can be used to call listeners before the source function is called. In Aspect Oriented Programming terminology, this is called "before advice" while the previous examples have all be "after advice". The terminology is confusing, but for a lack of anything less mind-bending or better accepted, we adopt it for the advanced cases that connect() supports.

Here's how we'd ensure that "bar" gets alerted before "foo" when exampleObj.foo() is called:

dojo.event.connect("before", exampleObj, "foo", exampleObj, "bar");

As you can see, we just perpended our previous call to connect() with the word "before". In the other cases, the word "after" was the implied first argument, which we could have added if we wanted, but typing more isn't something any of us want, and most of the time "after" is what you want anyway.

The same connection using kwConnect() looks like:

dojo.event.kwConnect({
type: "before",
srcObj: exampleObj,
srcFunc: "foo",
targetObj: exampleObj,
targetFunc: "bar"
});

Before and after advice give us tools to handle a huge range of problems, but what about when the listener and the source functions don't have the same call signatures? Or what about when you want to change the behavior of a function from someone else's code but don't want to change their code? If we take the view that any function call in our environment is an event, then shouldn't we also have an "event object" for each of them? When using dojo.event.connect(), this is exactly what happens under the covers, and we can get access to it via "around advice". Long story short, around advice allows you to wrap any function and manipulate both it's inputs and outputs. This'll let us change both the calling signatures of functions and change arguments for listeners (among other things).

Unlike the other advice types, around advice requires a little bit more cooperation from the author of the around advice function, but since you'll probably only be using it in situations where you know that you want to explicitly change a behavior, this is isn't really a problem. This example take a function foo() which takes 2 arguments and provides a default value for the second argument if one isn't passed:

function foo(arg1, arg2){
// ...
}

function aroundFoo(invocation){
if(invocation.args.length < 2){
// note that it's a real array, not a pseudo-arr invocation.args.push("default for arg2"); }
var result = invocation.proceed();
// we could change the result here return result; }
dojo.event.connect("around", "foo", "aroundFoo");

The aroundFoo() function must take only a single argument. This argument is the method-invocation object. This object has some useful properties (like args) and one method, proceed(). proceed() calls the wrapped function with the arguments packed in the args array and returns the result. At this point, you can further manipulate the result before returning it. If you don't return the result of proceed(), it will appear to the caller as though the wrapped function didn't return a value. At any point you could call another function to do things like log timing information. Once this connection is made, every time foo() is called aroundFoo() will check it's argument and insert a default value for arg2. Around advice is kind of like goto in C and C++: if you don't know better you can make huge messes, but when you really need it, you really need it. Despite the power of around advice, it's not very often that globally changing a function signature or return value is the best plan. More often, you'll just want to smooth over the differences in calling signatures between two functions that are being connected. As you might have come to expect by now, Dojo provides a solution for this type of impedance matching problem too. The solution is before-around and after-around advice. These advice types apply a supplied around advice function to the listener in a connection. They only apply the around advice when the listener function is being called from the connected-to source. Put another way, it's connection-specific argument and return value manipulation. To access before-around and after-around advice, just pass in another object/name pair to a normal "before" or "after" connection, like this:

var obj1 = { twoArgFunc: function(arg1, arg2){
// function expects two arguments }
};
var obj2 = { oneArgFunc: function(arg1){
// this function expects a two-element array // as its only parameter
} };
// we'd probably connect the functions somewhere else. Perhaps in a // different file entirely.

function aroundFunc(invocation){
var tmpArgs = [ invocation.args[0], invocation.args[1] ];
invocation.args = tmpArgs;
return invocation.proceed();
}
// after-around advice
dojo.event.connect( obj1, "twoArgFunc", obj2, "oneArgFunc", "aroundFunc");

Each function now gets what it expects, and the code calling obj1.twoArgFunc() never need be the wiser that any of this is happening.

DOCTYPE for XHTML documnets

2008-06-18T17:20:00.000+06:00

Recently I faced a problem while playing with dojo tree.The DnD within the tree was not functioning properly.I spent all the day to fix the problem and was getting frustrated as I couldn't figure out what was I missing. At the end of the day I suddenly could remember some buddy on the net wrote that DOCTYPE tag that we often overlook while beeing busy with some other stuffs is very important while playing with DHTML/XHTML documents.
So if you are a good web2.0 player be sure you are not missing your DOCTYPE tag on the very first line of you page :)
A sample DOCTYPE tag should look like:

PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

Ten Rules of Thumb for Business Success

2008-05-25T12:29:00.000+06:00

The best known blogger in France, Loïc Le Meur has ten rules for achieving success in business. I got it posted at one of my favorite site[anvari.org] and found it quite interesting and copied it all here:

Don’t wait for a revolutionary idea. It will never happen. Just focus on a simple, exciting, empty space and execute as fast as possible
Share your idea. The more you share, the more you get advice and the more you learn. Meet and talk to your competitors.
Build a community. Use blogging and social software to make sure people hear about you.
Listen to your community. Answer questions and build your product with their feedback.
Gather a great team. Select those with very different skills from you. Look for people who are better than you.
Be the first to recognize a problem. Everyone makes mistakes. Address the issue in public, learn about and correct it.
Don’t spend time on market research. Launch test versions as early as possible. Keep improving the product in the open.
Don’t obsess over spreadsheet business plans. They are not going to turn out as you predict, in any case.
Don’t plan a big marketing effort. It’s much more important and powerful that your community loves the product.
Don’t focus on getting rich. Focus on your users. Money is a consequence of success, not a goal.
