Evolution in the world of USB Mouse: Celluon evoMOUSE

evoMOUSE is a mouse that allows you to use your finger as a pointer in place of a physical mouse. It sits right at the position where you would usually place a mouse, and through its two infrared sensors that look like eyes, it allows the usual mouse functions: click and select, drag and drop, right click, and double-click. It also allows a little more functions similar to touch enabled devices such as rotate, pinch to zoom, and handwriting recognition, which you can do using your finger or a pen.

The device works on almost any flat surface and needs only a small amount of space, with the size of the unit itself also making it a high-quality option for taking on the road. It can be operated wirelessly via a Bluetooth connection or wired via USB, which will also charge the unit’s battery to provide around two hours of wireless running time. It is well-matched with PCs or laptops running Windows XP, Vista or 7, and Windows Mobile, BlackBerry and Symbian devices.

+1’s: the right recommendations right when you want them—in your search results

+1’s: the right recommendations right when you want them—in your search results: " Search should bring the most relevant results as quickly as possible based on relevance of words on webpages. Thats the reason Google has enabled an experiment to share recommendations with the world right in Google’s search results. It’s called +1—the digital shorthand for “this is pretty cool.”
Clicking on +1 on a webpage or ad you find useful you will recommend something and these +1’s will then start appearing in Google’s search results.

The +1 button will appear next to each search result

After pressing the +1 button, you have the option to undo the action immediately

To get started +1’ing the stuff you like, you’ll need to create a Google profile—or if you already have one, upgrade it. You can use your profile to see all of your +1’s in one place, and delete those you no longer want to recommend. To see +1’s in your Google search results you’ll need to be logged into your Google Account.


If you can’t wait to start seeing +1’s, you can opt-in to the launch by visiting our experimental search site. Initially, +1’s will appear alongside search results and ads, but in the weeks ahead they’ll appear in many more places (including other Google products and sites across the web). If an advertiser and want to learn more about how the +1 button works on search ads and websites, visit our AdWords blog.

To make round corner through CSS

For slightly round corder, use the code:

  -moz-border-radius: 20px;
   border-radius: 20px; 


As you will go on increasing the pixel from 20px to 200px

  -moz-border-radius: 200px;
   border-radius: 200px;

Corner will become more round. Try it yourself & find the difference

Now, take a look at this...
101%

From a strictly mathematical viewpoint:
What Equals 100%?
What does it mean to give MORE than 100%?
Ever wonder about those people who say they are giving more than 100%?
We have all been in situations where someone wants you to GIVE OVER 100%.
How about ACHIEVING 101%?
What equals 100% in life?

Here's a little mathematical formula that might help answer these questions:

If:
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
Is represented as:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26.

If:
H-A-R-D-W-O- R- K
8+1+18+4+23+ 15+18+11 = 98%

And:
K-N-O-W-L-E- D-G-E
11+14+15+23+ 12+5+4+7+ 5 = 96%

But:
A-T-T-I-T-U- D-E
1+20+20+9+20+ 21+4+5 = 100%

THEN, look how far the love of God will take you:
L-O-V-E-O-F- G-O-D
12+15+22+5+15+ 6+7+15+4 = 101%

Therefore, one can conclude with mathematical certainty that:
While Hard Work and Knowledge will get you close, and Attitude will get you there, It's the Love of God that will put you over the top!

Getting error "Retrieving unmerged branches Error:" when trying to push Rails application code from RubyMine

Yesterday, when I was trying to push the Rails3 application code from RubyMine, I got a strange error.
Errors was:

Retrieving unmerged branches Error:
Process failed to start (git branch --no-color): com.intellij.execution.process.ProcessNotCreatedException: Cannot run program "/usr/local/git/bin/git" (in directory "C:\projects\rails3_app"): CreateProcess error=2, The system cannot find the file specified

Let me explain the scenario about this error in a bit more detail. I had cloned a Rails application and committed in git as a branch of that application. Then I took checkout on other system and modified the code. When I was trying to push my changes through RubyMine I got the above errors and I was not able to push the code.

After long time of google and findings, I found the solution myself.
Reason of the error was that when we open any Rails application through RubyMine, it creates a ".idea" folder and that folder was commited when creating the branch. And when I took checkout of the code, the ".idea" folder of another computer's RubyMine setting was cloned on another system which was creating error.

Solution was quite a simple one. I just closed the newly created Rails3 project on RubyMine and deleted the ".idea" folder of the application. Then again I opened the project and this time I was able to push my code changes. Main point to note here is that you need to close the project from RubyMine before deleting the folder or else RubyMine will create the old folder again if the project is not closed.

How to debug jQuery is getting properly loaded or not

 What is jQuery and why it is used?
 

jQuery is a fast and concise JavaScript Library that simplifies HTML document traversing, event handling, animating, and Ajax interactions for rapid web development. jQuery is designed to change the way that you write JavaScript. 
For details you can refer to http://jquery.com/

There are many Rails application in which I have used jQuery. Many times when jQuery is added to the application we aren't able to run it properly. Basic problem, how to debug jQuery, how to test whether jQuery is getting called or not?

To answer such questions, you can write the below codes in layout where you are including jQuery.

    <script type="text/javascript">

   $(document).ready(function() {

      alert("test");

   })

    </script>

Following codes will give you alert "test" when application is loaded. This way you can be sure where your problem lies.

Any ideas why I am getting this error?

Open a web page URL in popup

Just now spent a lot of time searching for one solution. My requirement was to open a web page say www.google.com in a popup. That popup can be either thickbox, facebox, redbox or other similar popup box.

After some time of struggle, came across one solution which will definitely help in saving lots of other people effort. I did it with facebox and must admit, I didn't found it anywhere as simple enough to be directly implemented. It requires iframe along with facebox.

1. Download and install facebox from  http://chriswanstrath.com/facebox/.
2. For installing the facebox, lot of articles can be found, if you come across any issue, let me know.
3. Place the below code where you want to render the site:

<div>
  <div id="interactive_ad" style="display:none">
    <iframe height="500" width="800" src="www.google.com"></iframe>
  </div>
  <a href="#interactive_ad_1" rel="[facebox]">interactivea_ad</a>
</div>

And thats it. Now when you will click on "interactivea_ad" link, it will open a facebox popup and will display the site in popup.
