Facebook, the online social networking site, has added a new feature that takes your privacy and throws it out the window. There is an auto facial recognition feature that is ON by default. Unfortunately there are a lot of issues with this and they completely outweigh any positive points that this feature may have.
First off, this feature is ON by default. I personally know that my parents are TERRIBLE at adjusting the privacy settings for Facebook and the fact that this is on by default means that millions of people who DON’T want to have their face stored in Facebook’s database for recognition will have go figure out how to go turn it OFF. For the average person it should be fairly easy, but I know numerous people who just aren’t that great with computers. Those who aren’t computer literate will likely leave this feature on because they don’t understand, or don’t know how to remove it.
Secondly, this is a godsend for stalkers of any kind. All they have to do is just take a picture of someone they want, upload it on Facebook, and voila! There is all of their targets personal information! Being able to identify people without another person’s consent is a complete violation of the personal information that millions of people have entrusted to Facebook.
Are there any positive features about this auto facial recognition?
Yes of course. Now when you are uploading pictures you no longer have to tag people manually! That extra few seconds spent on each picture is now yours!
Unfortunately if you want this feature gone you’ll have to manually disable it.
How can I manually disable Auto Face recognition feature on Facebook?
You can do that by going to your Facebook page, go to Account then click the ‘Privacy Settings’ option. Once there, click ‘Customize Settings’. Once you’ve done that, scroll down and go to the ‘Things others share’ section. Click ‘Edit Settings’ next to the spot where it states the feature will use a comparison of photos to tag you in new photos. Switch this section from ‘Enabled’ to ‘Disabled’. Should you decide to change your mind later on, then simply follow those same steps and switch it from ‘Disabled’ to ‘Enabled’.
For a much easier way to learn how to disable this auto recognition feature, you can view the short video below.

If you are new to ‘webmaster’ing, one of the first things you should be aware of – is of robots.txt. For a starter who is figuring what robots.txt is, these two links will give you fair idea about it: link 1 and link 2.
When you discuss the advantages of robots.txt, different people have different views: some think it’s a very good idea to have robots.txt on their site, while others opine it’s not all that necessary. As they say, it’s to each his own. If you believe that having a robots.txt file on your domain will give you an edge, then go ahead and direct the Search Engine Bots what they should index and what they should exclude. If you are not concerned about everything on your server being indexed, then don’t bother using one. If you ask my personal opinion, I’d say, just for the heck of it have one, even if you want everything on your server to be indexed.
=> This link will give you some insight to advantages of robots.txt.
If you are wondering what possibly can go wrong with one ‘robots.txt’ file, then continue reading:
I had never put up a good robots.txt and one fine day I decided to put up one – Mistake !
Instead of carefully handcrafting a good robots.txt file, I decided to just randomly pick some code which was freely floating around on web, saved it in a text file named robots.txt and uploaded it onto the server- Big Mistake !!
So here’s what exactly happened:
Techbuzz is built on php, and the code which I found was blocking all the ‘.php’ files, as it was custom built for ‘.html’ sites. I overlooked this factor and went ahead. And the price I had to pay for it was: I lost more than 50% of my traffic in less than 24 hours !!
Luckily, Chibcha and Webado pitched in and their suggestions helped me regain a significant portion of the lost traffic.
Lesson’s I learnt from this mistake:
I guess by now you have enough information that’ll protect your website from any ‘robots.txt’ malfunction.
I’m no expert, but just an experienced webmaster. If there are any doubts regarding ‘robots.txt‘ please do drop a comment. I’ll answer if I have any idea about it, or point you to a solution at the least!
Is Google’s Chrome browser competing with Internet Explorer and Firefox ? Browser war: Which is the most preferred browser : Chrome / Internet Explorer or Firefox ?
Web browser you use is very crucial as that’s your gateway to chat, mail, search, shop, bank, read news and watch videos online. The browser war was always dominated by Internet Explorer for a real long time, though it is not the only best browser available, their marketing strategy had kept it ahead in the race so long. But, the statistics today has a different story to tell all together.
The browsers domain is saturated, with some of the best companies fighting for every bit of market share. The latest addition in the browsers section is Google’s Chrome.
Google introduced Google chrome browser with many advanced features like:
As Internet Explorer and Firefox were the leading web browsers when Chrome was released and to compete with them Google released an open source web browser engine Chromium. You can download Chromium code from here.
A web browser should provide good platform to the users and user friendly to get on with their things.
Keeping all these requirements in view Google launched Chrome with a more powerful JavaScript engine. It has additional “isolated” tabs feature to avoid collapse between browsers.
Google Chrome is built to add more value for users, to help them with viewing web information, related search, purchasing things and to work online.
What is the story behind Chrome ? Watch this video :
So who is the leader at this point ? Who won the race ? Which browser is better ? Guess this picture gives you basic insight to the above questions:
The statistics in the image above points out that Firefox is winner by a margin, with IE 8.0 almost catching up with it, and Google Chrome too has a significant chunk. If you consider all the versions of Internet Explorer, then IE wins by a margin, however, the popularity of Chrome has significantly increased in the recent past and it is a very tough competitor considering the time it has been available for.
We have to wait and see when it takes over the market, if at all it does !
It is not astonishing that the Xbox has bagged the top position on its sales considering the superior quality that it brings out. This has enabled it to over-power Sony PS3 and Wii, shooting to the top position of gaming consoles. Latest Microsoft reports say that sales have surpassed 3.5 million units until October and has been on a steady increase even after that. It has managed to maintain the same position for 5 months now.
This constant increase depends mainly on the availability of the gaming software. It is also the area where Microsoft has earned bonus points over others, because it has 6 out of the top 10 console games obtained for the month, along with such popular games like Halo: Reach and Fable111. This is enough to show that without sufficient software even the best of gaming stations can take a back seat.
If this is the status of gaming hardware[ a downfall], the gaming software on the other hand is on a rapid increase of sales and with Microsoft holding most of the top gaming softwares, Xbox can be at no other position than the top. In gaming, the user always looks for more thrilling games which is proved in the greatest Call of Duty: Black Ops. Xbox 360 supposedly gathered 59% of the Black Ops market in comparison to the 36% of PS3.
Sony and Nintendo have more cause to worry for the tough competition thrown by Xbox 360 Kinect’s popularity. And unless they can come up with better ideas, Microsoft has all the chances of remaining at the top. In October, the sales were prominent with Microsoft at 325000 units against 250000 units of PS3 and 232000 units of Nintendo Wii, speaking volumes for itself.
This result makes Microsoft the only console to have sold more units every successful year. It is important to note that these figures have been obtained before the launch of Xbox 360 Kinect which claimed to have sold over 1 million units in one day. The competition gets tougher with the approach of Christmas, for the new releases by Xbox360 Kinect and Sony PlayStation More, will determine their positions too.
On the whole, sales of video game hardware all over the industry has fallen by 26% to $280 million for October, while video gaming software sales have risen by 6% and accessory sales have shot up by 18% to reach a target of $142 million. Constant updates can be obtained through Twitter and Facebook Fan page.

Benefits of CSS Templates
There are lots of pros and cons of CSS templates, but the pros are primarily discussed in this article. Schematic table based designs are lagging way behind than CSS templates for development of the websites. Using of CSS templates are being recommended by most of the WWW (World Wide Web) companies. In the very first place, to design a web tables are not recommended and thus the table based designs are going to be replaced by CSS templates.
The pros of CSS templates are mention below:
CSS Flexibility:
Coding and presentation in the CSS layout are separated. For the website there is an external style sheets, if any designers make any change or improve the layout through the style sheet, then the following pages will also update accordingly. Let us suppose that to manage the appearance of padding, paragraph and margins a simple class is used for paragraph. Now if any designers have to change its appearance, then updating the style-sheets only will make the changes for all the other pages. Thus a CSS template is so flexible that the designers can save their valuable time and use that for productivity.
Rendering of CSS Codes:
The volume of codes required for table based design of websites was much, much higher than what is required for CSS layouts. Thus the reduction of codes gives a host of advantages for the users, making the performance of the website higher and simpler. There are many users who have dial up connection rather than broadband, so the reduction helps those users to load their WebPages faster. With the help of the CSS templates, the size has also been reduced, which reduces the time of loading of WebPages, making it quick and efficient in working
CSS Accessibility:
The main field on which any designers give more importance is accessibility, so that the user can interpret the WebPages properly and efficiently. It will be very difficult for any users to read and understand, with the screen reader, a webpage designed based on table and it is quite impossible to get the logic out of it.
No one can even imagine reading the tables column by column whereas there are table inside of another table. This is the problem not only to and the user, but also for the developers. If a developer misses out something from that table then he will be dammed to find that mistake. CSS templates make this work simple, logical and understandable by all.
