Continuing with it developmental efforts the Mozilla group has recently released the Firefox 3.1 beta 2 for download. Out of the several features that have been added to the latest version the most significant or important feature is the private browsing mode that lets you browse without any of your web history being stored locally.

It would be great for people who like to browse internet anonymously for some part while saving their browsing history for the other part, like a person trying to find a new employer at the work place. Once enabled it directs the Firefox browser not to store any of your browsing information.

As far as other browsers like IE 8, Safari, Google Chrome are concerned this is a already regular feature in them. Some other features that you may see added in the new Firefox are designed to increase the performance and the speed of Firefox, one of the areas where Firefox was losing to Chrome.

In this particular post I would like to mention some important thing while using a PC and also keeping in mind various measures that can be taken to bypass if anything goes wrong. So, the topic for today is keeping your data safe and sound. Well let’s start off with me. I try to keep my data safe and sound which is on PC so that I may not have to look around for data files if the PC ‘s hard disk gets corrupted or the digital Media gets damaged.

It is estimated that by the end of this decade millions of people will be using online backup services , mostly corporates have started using backup services because they can not carry their hard disks everywhere and even compact discs each time they move out of the country as there might be chances that in transit their data or presentations might get damaged as well. Because of the same reason I have also started using Online Backup to store my confidential data and even private data like photos,music and videos that I have made myself.

But before starting out to go for an online backup service you should check pros and cons of a service, their server speeds, their backup time , bandwidth availability, space available, whether upgrade possible or not, download speed, server maintainence and how many operating systems does the software support. If you find out the answers of all these questions in a satisfactory manner then you should go with particular service, if not then look for other service. In case you get a free trial that would be good to test the system as well.

All this gyaan would be a waste if you do not use backup service , if you are used to these sort of services then the following would never happen with you , or you would not try to patch your disc or try to get the data from it when it got broken.

Google has recently updated its popular chat service G Talk with video and voice chat features. Voice chat was always a part of G Talk but went missing in the Labs edition. It was a anticipated move after Gmail was recently updated with similar features.

Though GTalk has wonderful video quality it is even far from being a contender to the popular service Skype, but may be some time in the near future that we may even say that.

Talking a bit more about the audio and video quality they are just great and arguably so. The reason behind this that all the video and traffic passes through the highly efficient Google servers and we all know that Google has endless bandwidth and server space.

But unlike other services like Yahoo and Skype Google uses a 2 MB plugin that needs to be installed on the computer where you wish to use GTalk. This could be probably an issue with students who often hop around for their internet needs.

According to a study conducted in 2007 there were at least 2.7 billion mobile subscribers around the world connected with each other using either GSM or CDMA handsets and services. With the inception of mobile in 20th Century between (1960-1980) there have been drastic changes in the services being offered by mobile phones then and now. With the addition of 3G networks , the demand for quality contents has increased.

I myself have four mobile connections from different service providers so that I may be in contact with my loved ones and friends as well , not only this I too want different content for my mobile. In this context mobile marketing does play a very vital role and to manage these there should be a Mobile Marketing Company who can take care of our needs.

Imagine a small website can deliver products around the world and for its marketing it would require devoted team to handle the marketing campaign. Taking a small example , one of the websites using mobile technology started last year has delivered more than 130 million user generated SMS’es and has over 2.5 million users on it’s site. So imagine the potential of Mobile Marketing and it’s extensive reach.

Japanese won’t ever give up innovating newer robots. They seem to make robots for literally everything. Their latest robot cleans up the entire building all by itself. The robot that has been developed by the Fuji Heavy Industries and Sumitomo is being hailed as the future of industrial cleaning automatons.

To move from one floor to the other it uses the lifts just like us humans. The robot interfaces with the office elevators with the help of an optical control system and thus is able to eliminate the requirement of multiple robots on the different floors of the same building.

The robot can detect any kind of obstacles thanks to its laser sensors and camera. The only thing missing in this robot is its name. We hope it will get one soon.

Not so long back there was this news about a Facebook virus named “Koobface” that if executed would turn your computer into a zombie and so I thought it is the right time to reflect upon some of the deadliest PC viruses till date.

The point that you need to understand here is that Computer viruses like those mentioned below are still being regularly programmed and sent through attachments or downloads and therefore you should always try to avoid downloading any attachment from any unknown sender or any file from unknown site. But in case you do, immediately contact the computer repair centre and get it fixed.

Here are the 5 worst computer viruses till date.

First computer virus one in our list is Melissa Virus in 1999. It spread through Microsoft Word 97 and Word 2000. Using a mass email process it was able to access and delete critical Windows file. The losses were estimated to be around $ 1 billion.

Second computer virus one in our list is ILOVEYOU virus that appeared in the year 2000. The virus which spread through email used your email contacts to send more messages. The estimated losses were about $ 8.7 billion and roughly ten percent of all the computers that were connected to the internet were affected.

Third computer virus in our list is Code Red Virus that appeared in the year 2001. The virus benefited from the overflow vulnerability in Microsoft IIS servers and replicated itself in other MS computers. The overall losses were estimated to be around $ 2 billion.

Fourth computer virus in our list is MSBlast virus that appeared in the year2003. It affected over 25 million PC’s and losses were estimated to be about $ 10 billion.

Fifth and last in our list is Sobig Virus that appeared in the year 2003. The virus entered the PC in the form of an email attachment which if executed would collect email ids and send messages to all of them. It literally flooded the internet with emails. When it all got over the losses were estimated to be $ 1 billion with more than 500,000 computers affected.
