Microsoft released the source code for MS DOS 1.1 and 2.0 version and Microsoft Word for Windows 1.1 on March 25 2014. With the help of the Computer History Museum, they are making this code available to the public for the first time.

Initially on August 1980′s MS-DOS was renamed of 86-DOS which was written by Tim Paterson of Seattle Computer Products. In May 1981 Microsoft hired Paterson and bought 86-DOS for $75,000 in July, which was further renamed to MS-DOS. The First DOS version of word was released in 1983. In 1989, Word for Windows arrived, and within four years was generating over half the revenue of the worldwide word-processing market.

As this was quite a long time, and keeping these source code is really appreciated. Microsoft Research managing director Roy Levin had said-“Thanks to the Computer History Museum, these important pieces of source code will be preserved and made available to the community for historical and technical scholarship,”.


Full HD isn't the ultimate resolution anymore. Televisions have moved on, to greater and better resolutions. 4K, for the lack of content at present, is supposed to become the standard for Blu-ray discs and even for HD channels broadcasts, at some point of time. Let us run you through what 4K is all about.

What is 4K
The term 4K denotes a very specific resolution - 4096x2160 pixels, to be precise. This is the set resolution for anything that is recorded as true 4K content. Some people refer to any content with around 4000 horizontal pixels as 5K but that is strictly not true.

Is it the new Full HD?
Well, your Full HD TV has a resolution of 1920x1080 pixels. Along the way, silently, Ultra HD TVs came along with the resolution of 3840x2160 pixels. The 4K resolution display will have four times the total number of pixels on a 1920x1080p display.

Can any TV be 4K?
 No, the answer is that simple. Which is why, companies are spending a lot of money on making new 4K TVs.

So, can I buy a 4K TV?
Sony kicked it off with the mammoth like 84-inch 84X9005. This TV costs more than
$25,000 in the US. The company recently launched 65-inch and 55-inch versions for affordable costs (and definitely that's too is not affordable by all). LG got into the game as well, with the 84-inch HD 3D TV.
At the moment, unless you have a lot of spare cash lying around, that you desperately need splurge on, 4K TVs deserve the waiting game.

Where do I get the 4K content?
This is where things get tricky. With such a huge boost in the resolution, any existing 1080p content will also look weird on a 4K TV, no matter if somehow even upscaled to that resolution.
This brings us to the question of native 4K content. Yes, Sony is now selling the FMP-X1 4K media player for around US $800 in the U.S, with some content preloaded. The device has a 2TB built-in hard drive and web connectivity. The service that Sony is talking about, the Sony Video Unlimited 4K, is supposed to be rolled out later this year, and is expected to refresh the 4K movies and TV show line-up regularly. However, keeping the kind of broadband speeds most of us get here, we won't even dare consider downloading a 4K movie, if this service wwere to launch in Nepal in the near furture.
Alternatively, this content will also cost a considerable amount of money. It will not come cheap, with prices being quoted ranging aroung $30-$40 for buying a 4K movie in 4K discs

When will TV channels become 4K?
That is still quite some distance away. After the first 4K TVs from Sony and LG were unveiled late last year, a couple of channels did go live, one in Europe and one in South Korea. But at the moment, thats pretty much it. Most broadcasters expect them to start beaming before 2014, actually 2015 to be realstic. The FIFA 2014 World Cup  Final from Brazil is scheduled to get a 4K broadcast in Japan, but that is more the "on-demand" broadcast.

Forget the point-and-shoot Galaxy Camera from last year and feast your eyes on the Samsung Galaxy NX instead. It's the world's first ever interchangeable lens camera running on android and supporting 4G LTE cellular data. It lacks manual dials, but the Galaxy NX has a 20.3 MP APS-C sensor, 1/6000 shutter speed, built-in Wi-Fi, 16 GB onboard storage and a few other bells and whistles to push it into the high-end cameras category. It also lests you to connect to some popular social networking sites like facebook and lets you upload your pics directly.

Samsung Galaxy Gear

Samsung finally beat Apple into the wearable gadgets segment by giving the world a sneak peek into the Galaxy Gear, its first smartwatch. Sporting a 1.63-inch Super AMOLED (320x320 pixel res) display, 4GB internal memory, 512 MB RAM and an 800 MHz processor, the Gear's designed tp be a companion device for a smartphone, connecting over Bluetooth, pulling notifications and voice calls. It runs on a custom build of Android, offering good voice recognition features to interact with your phones in a handsfree mode. It also supports quite a variety of apps.

Samsung Galaxy Note 3

There's a brand new Galaxy Note phablet on its way for all who can't decide between a tablet or smartphone purchase. The device's 5.7-inch Super AMOLED screen touts a Full HD resolution and its frame packs a 13MP shooter with a whole host of dazzling features. It's slated to be available in two configs: the LTE version sporting a quad-core 2.3 GHz Krait 400, while the 3G only model featuring a quad-core 1.9 GHz Cortex A15 or quad-core 1.3GHz Cortex A7 SoC. It packs in a whooping 3GB of RAM, which should deliver a pleasant user experience and performance. And it comes with a stylus, too.

Watch the official commercial here :
China has build a new super computer which is about 74% faster than present fastest super computer at USA and Japan.Its name is given Tianhe-2 (also called Milkyway-2).

According to Computer World, the supercomputer can reach speeds of up to 54.9 petaflops. It has been built with Intel's chips, but also includes Chinese technology. The country's government has spent about $290 million building the computer.

It operates as fast as 30.7 petaflops - quadrillions of calculations per second.It runs Linux and has storage of 12.4 PB and memory of 1.4 PB.It also has 48,000 Xeon Phi chips, which is a co-processor based on Intel's Many Integrated Core architecture. Each of the Xeon Phi processors is capable of more than a Teraflop of speed.
Sony and Panasonic have announced that they're working together to develop the next generation optical discs. These discs will be capable of holding 300GB of data - considerably higher than the 50 GB that a dual-layer Blue-Ray can hold at  the moment - which can be read by standard players and hardware. Both companies believe that the discs will be ready for use by the end of 2015.

"Optical discs have excellent properties to protect them against the environment, such as dust resistance and water resistance and can also with stand changes in temperature and humidity when stored. They also allow inter-generational compatibility between different formats, ensuring that data can continue to read even as formats evolve. This makes them robust medium for long-term storage of content"said the jkoint press release from Sony and Panasonic.

"Both companies have previously developed products based on the Blu0ray format, leveranging the strength of optical discs. However, both Song and Panasonic recognized that optical discs will need to accomodate mucu larger volumes of storage in years to come given the expected furture growth in the archive marked and responded by formulating this agreement."

It's easy to understand why Sony wants to support the evolution with 4k content being critically important to irs 4k products since these discs will be capable of storing 4k movies.
Good care must be taken to ensure that a battery lasts a long life, this includes paying attention to it's charging cycles, the temperature, using the proper charger, etc. Here are a few pointers you need to keep in mind.

Your Li-ion battery has a limited number of charge cycles as time progress the capacity of the battery is going to reduce by a little bit till the point that you cannot aford to unplug the charger from your phone at all. As average  Li-on battery lasts about 1200 charges cycles. For example, if there are 365 days in a year and let's say you charge 3000 times a year, your battery should last 4 years before needing a replacement.

Li-on batteries also suffer from what is termed as the memory effect. When a battery is charged after having only been partially discharged, it sort of "remembers" the partial capacity, so the battery will show that it is fully charged when  it actually is not.  Given the cut-off mechanism in phones these days, when a battery tells that it is full the phone stops the charging, thus as your battery progress through its charging cycles, your battery life reduces by a small amount each time. This is why you should always discharge your phone as much as possible before commencing another charge cycle (i.e plugging the charger in).

How to protect

Use a few of your phone’s features as necessary to reduce consumption. Switch off Bluetooth, WiFi, 3G when not needed, smart phones these days come with a quick menu wherein these features can be managed without much fuss. Adjust the screen brightness to a level that is easy on the eyes and at the same time lower that half the screen’s brightness to ensure a long discharge cycle.An important factor to a consider for phones slightly older would be to use the proper charger that came with it, as the amperage of the current inflow may cause the battery to bloat if it is higher than what the battery was designed to handle. Nowadays phones use USB to charge so any compatible outlet should do fine but stay away from cheap chargers as they might not be up to standard and could cause some damage to your device. More at

Theory of How this Repair Works

First of all you can go ahead and make yourself an omelet and a banana split to keep you company during this project, as they do not really do a whole lot for repairing a CD as you may have seen on YouTube or equivalent. While some of you may have received positive results from using bananas and such, I have not, and I must say that the science just isn't there to back it up.
The theory behind fixing a scratched CD, is similar to fixing scratched paint on your car. The key is to polish out the deep scratches by using a substance that will create very fine scratches, and essentially polish the CD. To do this you can use any number of plastic polishes, rubbing compounds, and some have even reported good results with a metal polish, like Brasso.

Rubbing Compound (Polish) Method

I prefer the good old standby of automotive grade rubbing compound, such as from 3M. Admittedly, 3M polish is not necessarily a green product, it is after all synthetic in its basic composition, but you will need only a dab and quite frankly, there is no natural product that will even come close to the power of this stuff when it comes to resurfacing a badly scratched CD.
The experts tell you to always polish in a straight line from the radius of the center to the outside, rather than polish in circles. While this is good advice for the most part, since small circular scratches have been known to throw off the laser tracking system of a player, most tracking systems today are far superior to the ones we remember from the 90's. So, if you are willing to let the rubbing compound breakdown to its final stages, circle polishing can work well too.
When I refer to letting the rubbing compound breakdown, I am saying the rubbing compound formula essentially contains a grit that is designed to scratch the surface you are polishing, and wear down the deeper scratches until they are closer to the same height as the rest of the CD. It does this by starting out with a heavy grit, which breaks down over the polishing course into finer and finer grit, until it eventually leaves a mirror polished surface. But this is only if you put enough elbow grease into it.
I have found that circular polishing works just as well as radius polishing, but you can follow whatever advice you like, as this is simply a matter of opinion and personal experience. But what if you need to fix a CD right away and don't want to travel out to your nearest store to grab a bottle of polish, in such a case, toothpaste works reasonably well too.

Toothpaste Method


Toothpaste is designed much the same way as a rubbing compound, in that it is manufactured with a gritty substance, which gently scratches the enamel on the teeth, to clean and polish them. It can offer your CDs the same service, albeit not to quite the extend as the polish, but if the scratches are not too bad, it may just do the job.
Start with the most simple toothpaste you can find. I personally like Tom's of Maine Natural Toothpaste as it contains a basic enamel polish, without all the fancy gels, swirls, glitter, and bubble gum flavors. All you want is a good old fashioned white toothpaste. There is no need for frills here. Squeeze a smidgen of paste on the CD and rub it in using a straight sweeping motion with your finger from the center radius of the CD to the outside. Work your way around the CD using this motion until the CD is completely covered with a thin layer of the toothpaste.
If the CD is badly scratched, you may want to rub the toothpaste around the radius of the circle several times. Once finished, let the toothpaste dry to the touch. Hold the CD under your sink with running water and gently rub the tooth paste off. When satisfied with the cleanliness of the CD, gently dry it with a clean, soft cloth.

Finish with Some Wax


It is not a bad idea to put a coat of car wax on the CD (if you have some available). I prefer using an all natural 100% carnauba wax, which is made from the outside surface of a leaf. It is super strong and also friendly towards the environment. It will first of all, help fill-in any remaining deep scratches, second, protect the CD from being scratched in the future, and third, help repel any future dust and dirt from finding its way onto your newly cleaned and resurfaced CD.
Your CD should be good to play after all this hard work. If not, you can try the entire process once more and hope for better results. There have always been more than just one way to re-skin a CD, so share your own experiences, defeats, and triumphs with us.

You might have used Bitlocker to protect your drive from being accessed by others. If you haven't used bitlocker then don't worry I will guide you through the process later in this post. If you unlocked the drive locked with bitlocker, you have to restart the machine again to lock the drive. So I will guide you through some very simple yet the most effective process to lock your unencrypted drive again without restarting.

First I will guide you through the process of encrypting the drive through bitlocker. This is for those who don't know how to use bitlocker. If you have used bitlocker then please skip these steps and goto the next steps down here.

1. Goto "control panel"

2. Click on "BitLocker Drive Encryption"


3. Select the drive which you want to lock with bitlocker and click "Turn on Bitlocker" But remember, once the encryption part is started, you should not shutdown or restart your computer until the encryption is finished. Otherwise your whole drive would get damages and you will have yo format your drive. So if you have lots of datas stored in the drive, first move the files to some other location and put only few files in the drive which you want to lock.

4. Then provide the password that you want to use to unlock the drive in the furture. Then follow the steps properly.

5. Then setup will begin encrypting your drive, it will take a while depending upon your system and the space used by the disk. After the encryption finishes, your machine will reboot and the drive will be locked.

6. To unlock the drive you will just need to double click on the drive and provide the password that you set for it.

So the problem that you and most of the users will face is that when you unlock the drive, you will have to restart the system to lock the drive again. Well here's the solution. As I promised before, here are the simple steps to lock your drive again without restarting your computer.

1. Right click on "Command Prompt" and click "Run as administrator".
2. Now type manage-bde -lock x: on command prompt where,
                                                     'x' is drive letter u want to unlock

3. That's  it. Your drive will be locked again.

To do some higher level settings in your computer, you will require administrative privileges to perform the action. Even if your user account is administrator or even more, the only administrator, you still won't have the access to get administrative privilege. So follow these steps set up administrative privilege in your user account.

1.Click on "Computer".

2.Right click on the Hard Disk icon where your OS is installed on and click "Properties".

3.Click the "Security" tab.

4.Click the "Advanced" tab.

5.Click the "Change Permissions" button located after the Permission Entries list.

6.A new window will appear on your screen. Such a window contains a list of all the user accounts available on your computer.

7.Select the user account you want to give total control over your Windows and click the "Edit" button.

8.Now, tick the checkbox labeled “Total Control” and press OK.
You are done. Now you have finished setting up administrative privilege in your user account.
