What is DNS :An Introduction

You type a web address – say www.facebook.com – in the web browser, your computer queries a DNS server to find the corresponding IP address where that site is located and once it has that information, it routes your browser to the correct website.

That is a simplified definition of DNS but, behind the scenes, several parties could get involved as soon as your computer asks for the IP address of a domain name. There’s the Resolving Name Server, the Root Name Server, the TLD Name Server and finally the Authoritative Name Server.

Confused? You don’t have to be as here’s an informative short video that explains the entire DNS workflow in simple English.

Save Missed Calls to your Google Tasks with Any.do [Android]

Any.do is my favorite task manager for mobile. It is currently available for Android phones only but they are working on an iPhone app and also a web-based version that should make it available to all the other mobile platforms.

Any.do has a beautiful UI with large fonts and there’s voice input so you can add new tasks by speaking instead of typing on that small keyboard. My favorite feature though is the app's integration with Google Tasks. Any.do can sync your task list with Gmail both ways so you always have access to your tasks.

Add Missed Calls to your Pending Tasks List

The new version of Any.do’s Android app adds another interesting feature.

If there’s a missed call on your mobile phone and you are too busy to return the call at that time, you can quickly add it to your pending task list with a simple click. Thus, you would remember to call that person and since Any.do synchronizes with Google Tasks, all your missed call notifications would also be available inside Gmail.
