So let’s dive into the code. First I will show you the JavaScript functions I have used to set/read/delete cookie. Create a JavaScript file : “fasttwittter.js” or any name you want.

Note: I am specifying my cookie expiry in hours. If you want to do that in seconds then remove both the “60″s from the createCookie function and if you want to set it in minutes then remove only one “60″ and if you want to set it for days then multiply below value by 24. i.e seconds*24*60*60*1000.

function createCookie(name,value,hours) {
if (hours) {
var date = new Date();
date.setTime(date.getTime()+(hours*60*60*1000));
var expires = "; expires="+date.toGMTString();
}
else var expires = "";
document.cookie = name+"="+value+expires+"; path=/";
}

function eraseCookie(name) {
createCookie(name,"",-1);
}

Now we are ready with our cookie related functions. And now the real trick: Twitter update uses a JavaScript file called “blogger.js”. We will have to download this script and modify it and use it from our site instead of using the one from Twitter. Hence go to following URL : http://twitter.com/javascripts/blogger.js and save this script on your system.

Now we have to modify this script to save the feeds into the cookie instead of displaying it on your site.

In the blogger.js, replace the last line i.e document.getElementById(‘twitter_update_list’).innerHTML … etc … with following line
createCookie(‘twittercook’,statusHTML.join(”),1); // 1 => Number of expiry hours in this example.

Now lets go back to the “fasttwitter.js” file, where we had written the JavaScript functions and lets add one more function over there.

function loadTweet() {
document.getElementById('twitter_update_list').innerHTML = readCookie('twittercook');
// Twittercook is the name of the cookie I have specified. You can use any name you want
}

Above function will display “Twitter feeds” from the cookie instead of the site.
Now the call to the above function:

Note: I am using PHP to check if my cookie is set or not. You can even do that with JavaScript or other language if your site is not in PHP

<?php if(trim($_COOKIE['twittercook']) == "") { ?> //Checks if the cookie is set with the twitter feed, if not then fetch the latest tweets from twitter
<script type="text/javascript" src="[yoursite]/js/blogger.js"></script>
<script type="text/javascript" src="http://twitter.com/statuses/user_timeline/[yourusername].json?callback=twitterCallback2&amp;count=[count_of_tweets]"></script>
<?php } ?>
<script type="text/javascript">loadTweet()</script> //Function call to display the tweets
<?php } ?>


Now, my twitter won’t take ages to load. If you are someone who tweets every minute, then make sure you set the cookie expiry to minutes and not hours like in this example.

“This operation cannot be completed because the item filename.ext is in use”

and you would go crazy trying to delete it but it wouldn’t unless you restart your system.
One way to empty trash in this case is:

1) Drag the file from your Trash bin back to the Desktop.

2) Launch a Terminal i.e Go to Application -> Utilities -> Terminal and type the following into the terminal window leaving a space after -rf

cd ~/.Trash && sudo rm -rf

3) Drag that file you wanted to delete from your Desktop to the terminal window and then press Enter.

4) It will ask for your Mac password, so enter your password and press Enter. (Note: On terminal window, when you type the password, you won’t be able to see it, but the password is being entered. So don’t panic).

If you followed the steps correctly, then the trash will be emptied.
