Why should NFC be switched off when not in use?


NFC or Near Field Communication that you find in almost all modern smartphones except Apple products is a set of standards for smartphones and also any other device to establish radio communication with each other by simply touching the area having the embedded NFC chip together or bringing them into close proximity, usually only a few centimeters  This is a pretty hassle free method to make two like devices communicate.

All you folks who are using Android phones or tablets have a very easy way to regulate NFC and also NFC feature can be turned off very easily. But if NFC happens to be a service you use on a routine basis then you would want to think twice before switching it off all together. Since you will end up turning it on and off all the time, although it’s a very simple process. 

For the folks who don’t actually use NFC often (like me) you can just keep it disabled for quite a few very good reasons - save a bit of battery life and also keep your Android phone or tablet free from any malicious attack in the form of NFC transfer. To have NFC disabled, click on the apps link and scroll to find the “Settings” link. Then, tap the “More” option beneath the “Wireless and Networks” section. Some of these steps may slightly vary based on the phone you use and also the version of Android operating system that your phone is running.

Windows 8 Activation Key Serial Available for Free Download



Though we - the loyal customers need to wait a couple of months before we get the legal copies of Windows 8. The Windows 8 Activation crack is already available online for Free download. It has been barely a couple of weeks since Microsoft made available the RTM version of Windows 8 to the OEMs and lo we have the activation crack already available for Windows 8.

The Windows 8 Activation crack is available on a Chinese Forum(Link cannot be revealed due to piracy concerns). The Windows 8 Ultimate activation crack has been built on the OEM version of Lenovo's Windows 8 OEM DVD. The DVD ISO of Windows 8 along with the newly available crack is already leaked at the forum. Anyone who uses the leaked .ISO, along with the OEM-SLP product key of Windows 8, coupled along with the activation certificates can be obtained through the boot.wim - helps you run Windows 8Ultimate Final version.

The new activation crack uses a very simple technique of exploiting the "OEM Activation 4.3", which happens to be an updated volume license activation system by Microsoft that was earlier available from 2009 with Windows 7 and known infamously as "Activation 2.0". Looks like Microsoft hasn't learned from the mistakes coz, Activation 2.0 was previously the easy module break into Windows 7 way back in 2009 when Win 7 hit the stores.

The new crack which has been successfully been built on a Windows 8 volume license means that anyone who uses this cracked version can install Windows 8 on numerous machines without any limitations as such.

How to easily Uninstall Internet Explorer 9 when the uninstall program fails


Internet Explorer (IE) still continues to be one of the world's most used browser for several years now. Though in the recent times it has begun to get quite a lot of competition from Firefox and lately from Google Chrome.

With Windows 7 getting into the market and having a pretty strong presence users now have a very easy task of upgrading their browsers to Internet Explorer 9(IE 9) but just running the upgrade utility.

Microsoft says that users can very easily downgrade to their old browser version of IE anytime they want by simply uninstalling IE9 -  how this can be done is by navigating to Control Panel >> Programs and Features >> click on View installed updates option where you will see an entry for Internet Explorer 9. Right click and select the uninstall option. This should easily remove the IE 9 version from your PC and restore the earlier version of the Internet Explorer browser.

But many a times users get an error while trying to uninstall IE9 by following the simple method mentioned above or at times are not able to find the Internet Explorer 9 entry in the installed updates list. If that is the case, the you can easily follow the simple steps explained below to remove Internet Explorer 9 from your PC.

Step 1: Type CMD in Start menu search box and simultaneously press Ctrl + Shift + Enter keys(This is used to launch the elevated prompt). Click Yes when you get the User Account Control (UAC) prompt. The other way of doing this is by going to Start >> All Programs >> Accessories >> right-click on Command Prompt entry and then click Run as administrator - this will also open the elevated prompt.



Step 2: In the command prompt, copy and paste the below command and then press enter key to execute the command.
FORFILES /P %WINDIR%\servicing\Packages /M Microsoft-Windows-InternetExplorer-*9.*.mum /c "cmd /c echo Uninstalling package @fname && start /w pkgmgr /up:@fname /norestart"

Step 3: You are done almost!! Just reboot your computer to completely uninstall Internet Explorer 9 from your PC.

Hope this helped - if it did let me know!!

Why do you think thermal runaway reactions are dangerous on an industrial scale?


Thermal runaway reactions are always said to be dangerous on an industrial scale since the reactions go faster in an industry where they tend to reach higher temperatures. As you would already know that Exothermic reactions tend to release quite a large amount of heat, so when the reaction mixture gets very warm, a very very hot exothermic reaction begins. 

When you use industrial floor scales, it wouldn't take long to measure how and for how long the reaction needs to run to completion, so although it begins to get very very hot, it's soon over at the speed it started off with. When we see no more heat is being generated by the industrial reaction, and when it'll start cooling once the reaction is over. Did you know that for around 30 years manufacturers of some of the top of the line industrial weighing equipment with the best quality, accuracy, advanced technology and durability have always struggled to sustain it. 

When you have got a large volume of raw materials reacting, and that too in an exothermic reaction, it then begins to get hot, and finally it can quickly spiral abd get out of control. What happens is that the heat generated from the reaction can't escape, the reaction goes quicker, which then leads it to release even more heat, which speeds up the reaction even more. So that is how you have a thermal runaway reaction - in such a reaction even vessels cold melt, or explode. 

The raw material or even the product might boil away and be lost. At times it might catch fire and lead to very very dangerous situations. So that leads to the conclusion that exothermic reactions have to be run with plenty of coolant available which will help to keep the reaction at a manageable temperature. But on the other hand Nuclear power stations is another example where you don't want it to get too hot.

Norton 360 Version 4 – The best Anti-Virus solution till date


As most of you folks already know, I have become a fan of Norton products ever since I started using Norton Internet Security about 6 months back. The new Norton products and solutions have had a radical shift in terms of performance (which I deem very important), features and even the UI. This time round I got hold of a copy of Norton 360 Version 4 – the new kid(version) in the block!!

First things first – Norton 360, as the name truly suggests is a complete 360 solutions that truly runs out of the box from the time you say go (err… install). Norton 360 takes care of all things related to security for your PC / Laptop / Netbook and also takes care of a few more mundane tasks. It is packed with a powerful Anti-Virus, a super smart Fire-Wall, a password safe storage solution and also a auto-backup feature.

Lets deep dive into each of these features separately and the significant improvements that you get with the new Version 4.

Norton 360’s Anti-Virus Solution: One of the most powerful and yet light weight anti-virus solution that I have seen for quite sometime now and it’s getting better. The most useful and exciting feature that I find is called “Live Scan” – this is switched ON by default and runs whenever it finds the computer usage to be idle or low. “Live Scan” automatically determines whether to run a ‘Quick Scan’ or a ‘Full System Scan’. The advantage that I get with this cool new feature is that it runs usually when I’ve left my comp and gone to grab a cup of coffee or catch up on dinner – so no more hassles of setting up a schedule and making sure your comp is up and running for the scheduled scan to run.

I for once have had issues running scheduled scans – missing most of the schedules all the time, setting up a schedule over the weekend or late times of the day means that your machine needs to run over that time to hit the schedule. Now all that looks passé with this very cool and intuitive option. The best part of all this is that the scan magically ends as soon as you once again start using your computer – so you never feel that any of the computer resources have been sacrificed for the scan.

Norton 360’s File Insight Feature: How often do we download .exe’s / setups and what not off the internet – but how do we know that whatever you’ve downloaded is really legitimate and free of any virus, Trojan or root-kit. The later part is taken care by the anti-virus solution but never the legitimacy of the file. You are always left to make the decision yourselves based on the site from which you have downloaded, the person/forum that recommended it, etc – but even for a seasoned internet person like me, it’s quite a daunting task to decide. That’s when you’ve got help in the form of ‘File Insight’ which checks the file against an online database and reveals some interesting facts, let alone whether the file is safe to use/install. It churns out some cool facts such as the number of users who have downloaded/installed the file, safety level of the file and from where you got it to the physical location on your hard-disk that the file resides on. That’s a lot of cool and interesting facts to consider before you make a choice.

Norton 360’s Firewall : This is a very simple and lucid fire-wall solution, nothing much to worry on and it’s so very simple that if you can use your computer for browsing you can configure the firewall too easily. But I guess the default setting that Norton 360 ships out with is more than enough and you don’t really need to tweak any of the configurations frankly speaking. Also Norton's new SONAR (Symantec Online Network for Advance Response) behavioral monitoring system does a good task in combating phishing attacks and real time surveillance of your PC from attacks of the outside work over the network.

Norton 360’s Identity Safe Storage: Quite a cool option to store your usernames and passwords for the sites that you often visit. All the information is safely encrypted and stored. You now need to only remember one master password to access the safe storage.
But, I am really not a very big fan of this solution since it’s not portable really. In the sense, if I happen to use a public computer at a kiosk or over at a friend’s place – I really can’t harness this solution easily. Also, since I’ve become lazy in not typing the password’s each time to login – over a period of time one tends to forget the actual credentials. There must be a better solution for this problem but I can’t think of one that would be truly safe in all scenarios for now.

Norton 360’s BackUp feature: Looks like Norton is slowly consolidating it’s portfolio and that’s really a boon for users like me and you. The backup feature is pretty tidy and easy to setup and use. A few clicks on configuring your backup drive/media and the locations to backup – you should be ready to go. Believe me it’s a very simple process and best of all it’s right out of the box for all practical purposes.

Norton 360’s backup and recovery tool also provides you a free 2GB of online storage space that you can easily backup your important documents and photos. This free Online Backup is simply too cool if you’re out of home/office on a remote country with only a PC connected to the internet (read an airport) - viola you get access to all your backup files right there online.
Also for an extra charge you can easily increase your online backup storage up to 25GB at $69.99 per year. This is a very cool feature that the other backup / anti-virus products like McAfee currently donot do not offer today.

Performance has really been a deciding feature for me to switch over to Norton (this statement looked very very unlikely about 10 months back – if you were to ask me). There is absolutely no reason why you shouldn’t choose Norton 360 over the ample number of products that are out there in the market.

Norton 360 1 PC license costs INR 1795 - but the deal is with the 3 PC license at INR 3200, nowadays most of us have a desktop, laptop and netbook - so it does make sense to have a three license one - these also come with 2GB of online storage space. The premium edition includes 25GB of online storage space and a three PC license, the suggested retail price is INR 4025. Both - standard and premium editions of Norton 360 includes a one-year service subscription to use the product and receive Symantec’s protection updates. All Norton 360 users with a valid product subscription are eligible to receive the latest product updates via the subscription service model.

Norton 360 not only protects your computer but also tunes up your system for the best performance like doing a disk defragmentation or fixing driver issues and also backs up essential files – all in the background (now that’s the icing on the cake). The list of features and the great value for money that it provides is simply endless – as I started off this review, it’s truly an out-of-the-box solution where you deploy and completely let it take care of everything – all in the background.
