Camera Size: Compare the size of digital cameras

Thinking of buying a digital camera for your next vacation? Here is a online service that will help you easily view the different sizes of cameras. While many tools exist to compare technical characteristics, Camera Size lets you know the size of each camera.

Camera Size is a user-friendly web application that displays the exact dimensions of digital cameras to better compare. Operation is easy, just choose the two cameras that you want to compare from the drop-down list, and you�ll get the photo and the size of each camera.

The menu on the left sidebar allows you to choose the orientation of the camera (on supported models). You can rotate the camera left, right, top, front or back.

At the right side you can see an image of a regular AA Battery, which gives you an option to visualize the size of the camera. If that�s not enough, you can initialize a helper image of an average human male hand by clicking on the �Show hand�. You can drag this image around and position it under each camera and better visualize the size of the camera.

How to Test your vision online

Are you working daily on your computer and you want to test your eyesight?

ThinkQuest is an online tool to test your vision at home for free. This allows you to test your eyesight through a succession of letters becoming small. A bit like a doctor!

To take this test the application will ask you to choose the size of your monitor (you must have either a 15�, 17�, or 19� monitor), and your screen resolution, to measure out the correct length that you should sit back at (the length will vary depending on your screen size and resolution).

Now read the row of letters on the screen and press �next� to display more rows in decreasing sizes. When you can no longer read more than half the words on a line, press �stop� and you will get the result.

Of course this self eye test is no substitute for visiting your doctor but if you follow the steps well, you may get some idea about how good (or bad) your vision is.

ZenMate: Chrome extension for Free VPN with easy location switching

In a previous post we've learned What is a VPN and How does it work ? VPN is a network technology that creates a secure network connection over a public network such as the Internet.

ZenMate is a free extension for Google Chrome that will allow you to get a free VPN. A service that lets you connect anonymously and access sites that are blocked or censored in your country! Unlike other Chrome extensions � which are usually regular proxies without encryption - ZenMate will encrypt your browser traffic and build a secure tunnel around the data you send or receive. Your IP is hidden, your Internet unrestricted and your privacy protected.

How to use ZenMate and Change your IP:

Once you have installed this extension, a shield icon appears on the top right of your browser and you will be redirected to a new page that will ask you to enter you email to activate ZenMate. Then you will have a message saying that they �have sent you an eMail with your account credentials but you�re already signed in and can surf the web protected right away!�.

To access settings just click on the shield icon on the top right of your browser, to turn ON/OFF the service, (ON: the color of the shield turns green), you can even choose your location by clicking on �Change location�. ZenMate secure your connection and lets you access restricted content that only works in some countries such as Hulu.com or Pandora.com which only works in the USA, by changing the IP address location.

Download ZenMate for Google Chrome for free.

Note! The VPN is NOT a way to increase its anonymity for prohibited practices. A VPN does not make you completely anonymous and invisible !. It�s a way to protect your Internet privacy.
