THE BIG WHEEL

This piece of code pulls off all the images from your web page and rotates them in a circle. Really makes any page go naked (without its images). The best place to test is a website with many images. (Google Images for an example)

javascript:R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; DI=document.getElementsByTagName("img"); DIL=DI.length; function A(){for(i=0; i-DIL; i++){DIS=DI[ i ].style; DIS.position='absolute'; DIS.left=(Math.sin(R*x1+i*x2+x3)*x4+x5)+"px"; DIS.top=(Math.cos(R*y1+i*y2+y3)*y4+y5)+"px"}R++}setInterval('A()',5); void(0);

If you look carefully in the above code, its rotating the HTML “img” tag. Just replace it with “a” or “p” and watch some links or text rotate instead of images.

PLAY THE LORD OF THE WEB

This code lets you edit any page/website in real-time . With Firefox, you can even edit and save the modified pages to your computer. Very nifty code!

javascript:document.body.contentEditable='true'; document.designMode='on'; void 0

Ten Facts about Google

2010-09-03T22:39:00.000-07:00

1.The name Google is a spelling error. The founders of the site, Larry page and Sergey Brin, thought they were going for ‘Googol.’ Googol is the mathematical term for 1 followed by 100 zeros. The term was coined by Milton Sirotta, nephew of American mathematician Edward Kasner, and was popularized in the book, Mathematics and the Imagination by Kasner and James Newman. Google’s play on the term reflects the company’s mission to organize the immense amount of information available on the web. Initially, Larry and Sergey Brin called their search engine BackRub, named for its analysis of the of the web’s “back links.” The search for a new name began in 1997, with Larry and his officemates starting a hunt for a number of possible new names for the rapidly improving search technology.

2.The reason the Google page is so bare is because the founder didn’t know HTML and just wanted a quick interface. Due to the sparseness of the homepage, in early user tests they noted people just kept sitting staring at the screen, waiting for the rest to appear. To solve the particular problem the Google Copyright message was inserted to act as an end of page marker.
Google started as a research proj6.ect by Larry page and Sergey Brin when they were 24 and 23 years respectively. Google’s mission statement is to organize the world’s information and make it universally accessible and useful.

3.The company’s first office was in a garage, in Menlo Park, California. Google’s first employee was Craig Silverstein, now Google’s director of technology.

4.The basis of Google’s search technology is called PageRank that assigns an “importance” value to each page on the web and gives it a rank to determine how useful it is. However, that is not why it is called PageRank. It is actually named after Google co-founder Larry Page.

5.Google receives about 20 million search queries each day from every part of the world, including Antarctica and Vatican.You can have the Google homepage set up in as many as 116 different languages — including Urdu, Latin, Cambodia, Tonga, and Yoruba. In fact, Google has the largest network of translators in the world.

6.In the earliest stage of Google, there was no submit button, rather the Enter key needed to be pressed.Google has banned computer-generated search requests, which can sop up substantial system resources and help unscrupulous marketers manipulate its search rankings.

7.The Google’s free web mail service Gmail was used internally for nearly two years prior to launch to the public. The researchers found out six types of email users, and Gmail has been designed to accommodate these six.The free e-mail service recently changed its name for new UK users. Following a trademark dispute with a London-based Independent International Investment Research, the mail account has been renamed Google Mail.

8.It would take 5,707 years for a person to search Google’s 3 billion pages. The Google software does it in 0.5 seconds.Google Groups comprises more than 845 million Usenet messages, which is the world’s largest collection of messages or the equivalent of more than a terabyte of human conversation.
9.The logos that appear on the Google homepage during noteworthy days and dates and important events are called Google Doodle. The company has also created an online museum where it has all the logos it has put on various occasions so far.Dennis Hwang, a Korean computer artist in the United States, is the guy behind these witty Doodles. Hwang has been drawing the face of Google for over two years.

10.You have heard of Google Earth , but not many know there is a site called Google Moon, which maps the Lunar surface.
Google Moon is an extension of Google Maps and Google Earth that, courtesy of NASA imagery, enables you to surf the Moon’s surface and check out the exact spots that the Apollo astronauts made their landings

Google Moon
Keyhole, the satellite imaging company that Google acquired in October 2004 was funded by CIA.
Keyhole’s technology runs Google’s popular program Google Earth that allows users to quickly view stored satellite images from all around the world.

Important Facts about Sql

2010-08-24T01:00:00.000-07:00

Hi friends,
I am going to introduce some facts about sql commands hope you all will like it.

1) have you tried the command insert into ashu(max(id)+1,'deepu');
i tried it to insert id(last max(id)+1) automatically in serial order.but it fails.guess why??
because insert statement does not take group function in insert statement.

2)CASE – similar to IF/THEN/ELSE – used to turn Rows into Columns
Syntax –
SELECT a,b,c,
CASE WHEN(condition) THEN action ELSE action
FROM table_name
COALESCE – similar to IFNULL – returns first Non-NULL value in a list of values
Syntax – COALESCE (value1,value2)

EXTRACT – can be used to Extract Date parts –
Syntax - EXTRACT(month FROM date_field) or SUBSTR in Oracle

UNION and UNION ALL
Beware that UNION ALL is usually required –
because UNION implies a DISTINCT that does not return all the qualifying records.

Avoid Dividing by Zero – use NULLIF

2) what is the use of dual in sql? plz post your answers.i will be posting its answer with in some weeks(;-))

2010-08-20T23:41:00.000-07:00

Hi friends.
when it come to joomla 1.0 component development, there is one and only one thing that is need to be take care of, is the TASK(eg. delete,edit,cancel etc) that you pass in the component.
some time we pass the task through hidden fields also so that we can get it through the $_REQUEST(all though you can use $_POSTor $_GET but i would advice you to use $_REQUEST).

When building Joomla! components, modules or plugins we can define all configuration parameters through XML files. Some common parameter types are predefined and can be used in our Joomla! extensions.

Parameters in the Joomla for modules

Every parameter you define must have five basic attributes.

Parameter name, so you can reference it later in your code.
A default value to be displayed and used if no value is chosen.
A visible label
A description appearing when the mouse cursor hovers over it
The type of parameter
A categorized list is below:

Content

section - All published sections in a list category - All published categories in a list

Text Input
text - A standard text input
textarea - A plain textarea field
password - A standard text input where the characters are masked as they are entered editors

Selections

folderlist - A list of folders to choose from, given a base folder path
imagelist - A list of images to choose from, given a base folder
path list - A list of items to choose from
radio - A list of radio selection items to choose from

Predefined

How to use H1 and H2 tag in the content pages

First of all i would like to tell you why we concerned with h1 and h2 tags,because they just help to optimize the page on the google(because google look for h1 and h2 tags for good optimization of the page on goolge page rank system).
in joomla 1.0 just look for the
function Title( &$row, &$params, &$access ) {

if ( $params->get( 'item_title' ) ) {
if ( $params->get( 'link_titles' ) && $row->link_on != '' ) {

?>

after the above code look
in the content.html.php and replace the "contentheading" class(its pre defined css file) with the h1 and the contenttitle with the h2 tag.
same in the joomla 1.5.I was just looking for the same solution but i found very confusing articles.

In simple words when ever you see content heading or content title replace the class with the tag you want. just replace td with the h1 or h2 .
