Here in this Article I will try to cover up all the aspects about Bitcoin.
Bitcoin is a Digital Currency used in e-payment system. This is in place for quite a sometime now, but the risk that it comes with cannot be ignored.

The internet has revolutionised so many aspects of our lives. A new language, coding, designing, art, cooking — things you would normally expect to pay for – are all available online for free. Here are 7 courses in varied streams that can be availed online for free.


To get started with the basics of photography, you should visit This is a site without any distracting ads and with content neatly laid out by skill level.

At, you’ll find a handy collection of (regularly updated) articles and tutorials from photo professionals. And when you need to brush up on your photography jargon, the ever-popular DP Review has a comprehensive listing at www.

On the app side, Photography Tutorials (by Anton Gregory) is a great free app for Android devices. This app curates and organizes a large list of photography tutorials from around the web — practically any beginner or advanced technique that you need to know about is here.

Computer Programming
For javascript, jquery, PHP, Python and Ruby, head to The interactive website offers step-by-step instructions to familiarize you with the language, shortcuts and other instructions.

You don’t even need to sign-up, but do so if you want to keep track of your course and resume from where you left off. A free iPad app called Treehouse can teach you Objective-C, HTML, CSS, JavaScript, PHP, Ruby, and SQL. There is also a dedicated section for iOS and Android app development if you are interested in it.

You get access to various tutorial videos for learning, which are constantly updated with new updates. As you move ahead in the course, you have to take a regular quiz and complete interactive challenges.

New Language
Depending on what you currently speak, some languages are easier to learn than others. For instance, if you know English well, it’ll be easier for you to pick up Spanish rather than Russian.

The courses hosted on are a pretty good place to start. Duolingo is another great place to learn Spanish, English, French, German, Portugese or Italian. Duolingo ‘gamifies’ the process with rewards. They also have free apps for iOS and Android.

Other popular services include Live Mocha and Lang-8. While you learn, you also act as an editor for someone learning your native language — this keeps everything free.

Cooking is a fine art — any seasoned chef or homemaker will tell you that cooking is not just about combining ingredients — it’s also about applying hundreds of little tricks and techniques that usually take years to master.

Luckily, you can find a lot of tips on basic cooking techniques at (they also offer free apps). Over at, the ‘How to cook’ tab will help you brush up on roasting, poaching, grilling, frying, braising, baking and everything in between.

A handy cooking converter at the bottom of every page can help you convert quantities: tablespoons to teaspoons, litres to pints and so on. For apps, two of our favourites are All Recipes and Epicurious (free, for all platforms). They’re easy to use, attractive and customised for each platform.

Artistic Skills

It’s possible to learn art at any stage as long as you have the motivation. To learn the basics (colours, drawing techniques, perspective and so on), head to

Meanwhile, at you can find a list of art lessons, tutorials, articles and videos curated from around the web. When you want to do more, head to — where you can learn how to do stuff as diverse as watermelon carving, making jewellery, puppets, and costumes.

You’re also welcome to share your ideas with the community. On the apps side, How to Draw by ArtelPlus (for iOS and Android) is a good place to start. There’s also a huge range of apps available in the ‘How to Draw’ series — each app teaches something specific.

Self Defence

You won’t be able to learn advanced self defence techniques or master a competition, but you can easily pick up and practice basic martial arts and self defence with some online help.

Lifehacker has a great, one-page guide to basic self defence that can get you out of a sticky situation. This includes tips on vulnerable parts of the body, how to attack, leveraging your weight, basic kicks/punches and how to administer/get out of basic holds.

You can find the guide here — For apps, you can try the Self Defense Trainer by Bizapp Media.

Unlike most others on this page, dancing needs you to ‘do’ more than read or look up. That’s why tutorial videos on various dance forms on YouTube are the first place you should look.

Next, head to www. and you can start learning different dance moves and styles (hip hop, pop, street, break dance, krumping, ballroom and so on). Beyond that, practice is what you need.

Free Courses from Top Universities

Prominent names like MIT, Harvard, Berkeley, University of Texas and University of Toronto offer free online courses that anyone can access.

You can either visit the individual websites of these institutions or head to Edx accumulates all free courses offered by institutions across the world across subjects.

Choose a subject of your choice, select the institution you want to learn from and join a course. There is no prerequisite knowledge required for most courses and you get access to various videos, transcripts and notes.

You can even earn yourself a certificate of course completion from Edx if you do all the homework and pass the exam for a particular course

In the Compose tab of Gmail, as you start typing out in the ‘To’ field, you are prompted with probable email addresses. It’s convenient, no doubt, especially when you can’t recall the email ID. But it could lead to an embarrassment, when in a hurry you end up sending the mail to the wrong person.

Gmail has an option, wherein within a specified period of time, you can recall the mail you sent. To enable this useful tool, click on the ‘Gear’ symbol on the top right of the email page, and go to ‘Settings’. Click on ‘Labs’ in the series of options you see on the top of the page.

Scroll down and look for the ‘Undo Send’ option. Click Enable. Scroll down and click on ‘Save changes’.

Click on ‘General’ in the top row of options. Scroll down and look for the ‘Undo Send’ option. Check ‘Enable Undo Send’, and choose from the options for cancellation period. The minimum is 5 seconds and the maximum is 30 seconds. Scroll down and Save Changes. Now, when you send a mail, it wouldn’t go for the period of time you have selected, within which you can Undo Send.

Here are few MCQs on Database along with Answers and Explanation.


Image processing has certainly brought visual world closer to programming world. In imaging science, image processing is form of signal processing for which the input is an image, such as a photograph or video; the output of image processing may be either an image or a set of characteristics or parameters related to the image. Most image-processing techniques involve treating the image as a two-dimensional signal and applying standard signal-processing techniques to it.

Image processing usually refers to digital image processing, but optical and analog image processing also are possible. The acquisition of images (producing the input image in the first place) is referred to as imaging. Here we will be particulary interested in Digital Image Processing. Digital image processing is the use of computer algorithms to perform image processing on digital images. As a subcategory or field of digital signal processing, digital image processing has many advantages over analog image processing. It allows a much wider range of algorithms to be applied to the input data and can avoid problems such as the build-up of noise and signal distortion during processing.

So we have selected this particualar project to detect salient object in a static image. On future scope the project can be extended to detect salient object on video as well. The abstract for the project is mentioned below to provide you with some input regarding the project.
