No, So what can we do in this case? There are two solutions,

1 – rename the new image and change the image name in code. But for a dot net developer this is pain because he may have to republish the code and send an upload of the dll again. And giving an upload of dll because of change in image is foolishness, ain’t it?

2 – Another solution is to write a javascript code so that the browser does not pick up image from the cache and loads it everytime. Following is the sample code of how you can try this,

document.getElementById('myimg').src = document.getElementById('myimd').src + '?' + (new Date()).getTime();

You need to make sure this code runs after page has loaded else, it will give an error if that image tag is not yet rendered.

In JQuery for single image code will be

$(document).ready(function(){
$("#myimg").attr('src',$(this).src + '?' + (new Date()).getTime());
});

For all the images

$(document).ready(function(){
jQuery('img').each(function(){
jQuery(this).attr('src',jQuery(this).attr('src')+ '?' + (new Date()).getTime());
});
});

Hope this helps. If you have any more idea please share it with us by dropping a comment.

JParallax

jParallax turns a selected element into a 'window', or viewport, and all its children into absolutely positioned layers that can be seen through the viewport. These layers move in response to the mouse, and, depending on their dimensions (and options for layer initialisation), they move by different amounts, in a parallaxy kind of way.

And here is the Bing’s Design

Bing's Design

Google didn’t checked the Bing’s design? or Google liked the Bing’s design so much? What’s your say on this?

Make the following changes in top-admin.php file

1 – Look for the URL shortner drop down list, find the code that looks like below

'.__('URL Shortener Service', 'TweetOldPost').':

'.__('is.gd', 'TweetOldPost').'
'.__('su.pr', 'TweetOldPost').'
'.__('bit.ly', 'TweetOldPost').'
'.__('tr.im', 'TweetOldPost').'
'.__('3.ly', 'TweetOldPost').'
'.__('u.nu', 'TweetOldPost').'
'.__('tinyurl', 'TweetOldPost').'

2 – Once you get there, add another option tag to the list like below,

'.__('urlshortner', 'TweetOldPost').'

Note – In the above option replace ‘urlshortner’ with new shortner name.

Make the below changes in top-core.php file,

1 – find the function shorten_url(), and add an elseif block of new shortner api like below code,

elseif ($shortener=="urlshortner") {
		$url = "http://u.nu/unu-api-simple?url={$the_url}";
		$response = send_request($url, 'GET');
	}

Note – replace urlshortner with new shortner name, it should be same as in point 2 of top-admin.php changes. In the URL section change the API URL with your shortner API URL and pass the required parameters the above just have the URL parameter.

2 -Some API may require additional parameters like API key. So it will look somewhat like this,

elseif ($shortener=="urlshortner") {
		$url = "http://yourshortnerapiurl/api?url={$the_url}&api=xxxxxx";
		$response = send_request($url, 'GET');
	}

Note – replace urlshortner with new shortner name, it should be same as in point 2 of top-admin.php changes. In the URL section change the API URL with your shortner API URL and pass the required parameters. The above have the URL parameter and API key replace xxxxxx with your API Key value.

That’s it and you are ready to go. In case you find it difficult to implement the above code feel free to drop by a comment I’ll add it for everyone and you can always drop me a mail.

//source and args are required if calling from custom validator in asp.net else its not required
function htmlValidation(source,args)
{
var re = /(<([^>]+)>)/gi;

if (document.getElementById(’<%=TextBox2.ClientID%>’).value.match(re)) {
document.getElementById(’<%=TextBox2.ClientID%>’).value = “”;
alert(’Invalid content’);
//args.IsValid = false; // you can use this if you are calling this from custom validator in asp.net
return false;
}
if (document.getElementById("textboxid").value.match(re)) {
document.getElementById("textboxid").value = “”;
alert(’Invalid content’);
return false;

Just add this code on your page load and the menu control will start working fine in Google Chrome as well.

Also some times the hover menus don’t work on IE8 to make it work on IE8 you need to set

“z-index”

Here are some of the applications supported by opera unite. I am going to give example of Opera Unite File Sharing.

List of Opera Unite Applications

Opera Unite file sharing configuration options.

Opera Unite File Sharing Configuration

This is how your screen will look after file sharing configuration it will show all the files from the folder. You can also see the password option on the right bottom. Once set it will ask the password to the person you send the link to.

Opera Unite Web Sever Application

Opera may not be as popular as Internet Explorer or Mozilla Firefox, but the Opera browser has forged a reputation for being one of the most innovative in the world. It was the first to come up with tabbed browsing – the option to open multiple websites in the same window – and also on efot he pioneers in synchronising bookmarks on the desktop browser and mobile phone browser. And now, with its latest version, 10.10, Opera has once again added  a new dimension to browsing, by including a server in the browser itself.

If that sounds like Greek to you, then here is simple version – with the new Opera browser, you can share pictures, music, documents and just about any file with the people you want. You can do it without having to upload any file to a website or attach it to an e-mail. That’s right, no more twiddling your thumbs while you wait for your pictures to get uploaded to Facebook or Flickr or Picassa; or sauntering off to brew some coffee while your detailed multimedia presentation gets attached to your e-mail over a broadband connection that tends to struggle more often than not. You do not need to even compress or zip up heavy files, all you need to do to share information is click a few buttons.

Making all this magic happen is a part of the Opera browser called Opera Unite. Cutting out the fancy server jargon, it lets you specify which files on your computer – documents, music, video – you would like to share it with your friends. Once you do this, it generates a URL. Now, all tha remains to be done to make sure your friends to view the file – just send them the URL and ask them to enter it in their browser. That’s it – they will bea bel to see the content you wish to share. The concept is as simple as browsing the internet – when you enter the URL of a website you are taken to the server that hosts the website, so that you can see it. Opera unite actually turns your computer into the server – so when a user enters the URL you sendd him or her, they are actually looking at the files on your computer itself. You can even play music on your computer and let your friends hear it on theirs. No uploading or downloading involved.

Of course, this does raise the specter of security issues – after all, people are looking at information on your computer. Well, there is a password option that ensures that only those users who enter the correct password can access the information you wish to share. Discretion is, however, advised.

There are those who will sneer at this feature, pointing out that this is very similar to peer-to-peer (P2P) computing where two computers connect to each other and exchange information, and can therefore be done from just about any browser like the Internet Explorer or Mozilla Firefox. While this is indeed true, the fact is that none of the browsers out there have a server installed within them, which really simplifies the task for the user, who has no additional software or plugins to download. All one needs to do is grab Opera 10.10 from www.opera.com and signup for a My Opera account. Opera 10.10 costs nothing, in best browser tradition.

There are other features worth a mention in the browser, such as Turbo browsing option that lets you download pages faster and Visual Tabs, that let you drag the handles below the tabs to get snapshots of the web page you are browsing, but it is Opera Unite that we see changing web browsing as we know it.
