All you need to do is click the link below to crash a computer. Works on both MAC and Windows.

Disclaimer: This seriously works. Before trying make sure you have all your works saved. Only way to come out of this is to pull the power off your computer/laptop. Proceed at your own risk

Ok so you tried or not tried but want to know how it works?

The exploit basically triggers multiple instance of your default mail client and ends all your computer resource (CPU/RAM) and hangs the computer.

Here is how it works. Typing the following url on your browser will open your default mail client with fields populated. If you don’t know you can try it. Its safe.

mailto:somebody@somebody.com?subject=Hell Ya&body=Check my Site.. classictutorials

Now in a HTML page if you just give the same in an iframe it will basically do the same. Reloading the page will open one instance of mail client.

<iframe src=”mailto:somebody@somebody.com?subject=Hell Ya&amp;body=Check my Site.. classictutorials”></iframe>

If above script opens one instance of mail client, what happens if we have similar 100 entries in a page and just reload the page say every 5 sec.. IT BECOMES EVIL

You can do a HTML reload using

<meta http-equiv=”refresh” content=”5;url=current page URL“>

Cheers! Bring it on

Quoted from V1.o

This plugin lets you show a different greeting message to your visitors depending on their referrer url. For example, when a Digg user clicks through from Digg, they will see a message reminding them to digg your post if they like it. Another example, when a visitor clicks through from google search they will see a message suggesting them to subscribe to your RSS feed. Having these targeted suggestions will help your blog increase exposure, loyal readership, and reader interaction so all together it should increase your page hits.

For anyone who don’t know much about the previous version should check this URL. It all started more than 2yrs back. If you want to check all previous versions here it is.

Hope you like the release. Would like to hear from all of you.

All you need to do is follow this Reditt post and you get all the new and unique way of status updates.

QR code algorithm works even with 30% error in it

First thing came in my mind was a 30% destorted QR image should work then. And saying so i started doing some research on internet and figured out its very easy to destroy a QR and still make it work.

First thing i did was went here http://zxing.appspot.com/generator/ and created a sample QR code.

Then installed a QR reader on my phone. There are lot of free QR application. Just search in your market place with “QR”.

The actual output:

Opened Photoshop. All good and let the game begin.

Stage1: (Click Images for larger view)

Lets make it colorful like those Japanese festival.

Worked!

Stage2:(Click Images for larger view)

How about a colored image inside it.Think of putting some branding.How about a colorful company logo? Just a random image. Scanning with an apple iphone so added a pineapple image #PJ

Ok must say it was bit complex then it looks. I was forced to reduce the size of the pineapple little by little and stopped at the point as soon as it started working.

Worked!

Stage3:(Click Images for larger view)

Thinking about branding again.This time more complex.How about some alphabets like a company name. Trying with my name.

Ok this was most complex. Worked after several attempts. But this looks the best. I have written the text in white and gave a black background to make it look better.

Worked!

Game over

Try out some more combinations and its really fun. Make sure to keep your phone and a photo editing app like photoshop or GIMP handy as it take lot of hit and trials.

There are few hacks you can do to enable it. Like editing the plugin XPI file with a notepad. Or enable compatible through about:config for each plugin. But this is the easiest way. Just install the following plugin. Restart your browser and done.

PLUGIN: Compatibility Reporter

Ok if you have not you can think now. Google has this unique service called Google News Archive which digitalized lots of old news papers. Check the screenshot below.

URL:Google News Archive

We work closely with newspaper partners on a number of initiatives, and

as part of the Google News Archives digitization program we

collaborated to make older newspapers accessible and searchable online,

-Google

But the bad news is they have recently stopped the archiving service but still there are already lot of information available in there databases.

We don’t plan to introduce any further features or functionality to the

Google News Archives, and we are no longer accepting new microfilm or

digital files for processing.

-Google

To learn about Mozilla location share you can check this: Mozilla Geo Location

OR for Chrome you can check this: Chrome Geo Location

To understand the basics:

A DOM object is provided in all new browsers (FF 3.5+ and chrome 7+[I don't count IE as browser, as usual it doesn't supports this feature also]) called navigator.

A document about the same is provided here for more understanding of extended features but i will try to cover the basics in this post.Geolocation API Specification

Note: Each time such code is executed your browser will ask for permission.

Enough of those reading stuffs, lets do some coding.

navigator.geolocation

The above object is all about location.

A sample code would be

if (navigator.geolocation) {
 navigator.geolocation.getCurrentPosition(function(position) {
 doStuff(position.coords.latitude, position.coords.longitude);
 });
 }

In the above code

position.coords.latitude, position.coords.longitude

will give you your current latitude and longitude. We can pass this to something and use. Say for example in my doStuff function I pass the same to google map and show the current map location.

Demo: Geo Location Demo

For more HTML5 resources check this.

Note: Using the same data and Google map API we can use it to pre-fill registration pages like Google do for orkut registration page.

A QR Code is a matrix barcode (or two-dimensional code), readable by QR scanners, mobile phones with a camera, and smartphones. The code consists of black modules arranged in a square pattern on white background. The information encoded can be text, URL or other data.

-Quoted from wikipedia.org

Now as you can see in this site i have added a dynamic QR code on each post. So for each post a dynamic QR code gets generated. Very simple use of third party sites.

I did a bit of web search and figured out there are mainly 2 websites which provide QR <Embed> code. I just modified them a bit with javascripts. You can use any one of the two.

TO USE:  Just copy-paste any where in your website and it should start working.

1) goqr.me

To change the image size just modify the “size=150×150” to what ever equal value you want.

Code:

<script type="text/javascript">
var uri=window.location.href;
document.write("<img src='http://api.qrserver.com/v1/create-qr-code/?data="+encodeURI(uri)+"&size=150x150'/>");
</script>

2) kaywa.com

To change the image size just modify the “s=5” value to what ever you want. Highest is 12.

Code:

<script type="text/javascript">
var uri=window.location.href;
document.write("<img src="http://qrcode.kaywa.com/img.php?s=5&d="+encodeURI(uri)+"" alt="qrcode" />");
</script>

NB: The bigger the image better for lower end mobiles because of there lower camera capability.

Google has partnered with in.com, saavn and saregama. Its cool. Tried searching some new songs. Also the search result page you can directly play each songs.

Go ahead and give a try. I have defaulted the text inputs with my id, 2 celebrity id and 1 engadget id and the feed is a merged twitt of every one and sorted by time. Let me know your comments.
