Selenium is designed for automated software testing by simulating user's action on web pages. Since it does DOM and HTML parsing it is well suited for my project.

The word camera comes from the Latin words camera obscura, which mean “dark chamber.” This is because the earliest experiments with capturing images took place in a darkened chamber, or room.

One can extend this script to First collect all the profile links by crawling from My network page and then running a for loop to visit each profile to scrap data with the above-discussed method. Which can be saved to CSV file.

I went on research to figure out techniques people were using to scrap web and came across various web crawling framework like scrappy, Pyspider, MechanicalSoup, Cola, Selenium.

In the late 1800s the U.S. inventor George Eastman made a camera that brought photography to the general public. Before this time cameras were heavy, complicated, and expensive. Eastman’s camera was small and easy to use. People simply pushed a button to take pictures and then sent the film to Eastman’s factory to be printed.

The U.S. inventor Thomas Edison and the French Lumière brothers developed movie cameras in the late 1800s. Digital cameras did not appear until the 1990s.

In ancient times people used a camera obscura to view eclipses of the Sun. They stood in a small, dark room that had only a tiny hole to let in light. An upside-down image of the scene outside appeared on the wall across from the hole. Later, people made portable boxes that worked like the ancient camera obscura. A mirror reflected the image outside the box and onto a screen.

There are many types of traditional cameras. Some are fully automatic. This means that the camera focuses and allows in the right amount of light to take a good picture. The photographer needs only to aim the camera and press a button. Other cameras allow the photographer to make these adjustments by hand.

I selected to go with Selenium since it is industry standard and I found its documentation well explained and easier to start with.

A digital camera works in a similar way as a traditional camera. However, it captures the image on an electronic chip rather than on film. The chip is a light sensor that turns the image into electric signals. Most digital cameras have a small screen that displays the image right away. The camera can also store the image on a memory card. Photographers can transfer the stored image to a computer. This allows them to view, e-mail, or print out the image.

A traditional camera is a lightproof box. The box contains an aperture, or opening, that lets light in for a certain amount of time. A part called a shutter opens and closes the aperture. This controls the amount of light coming into the camera.

Movie cameras are like traditional cameras, but they record moving images. They do this by taking many still pictures in a row—usually 24 or 30 each second. They record images on a reel of film. When a movie projector shows the pictures on the film one after the other, the images appear to be moving. Video cameras, or camcorders, record moving images on magnetic tape. Digital camcorders store moving images as electric signals.

A camera is an instrument used to take, or record, pictures of people and objects. Some cameras record single, still pictures called photographs. Movie cameras and video cameras record moving pictures. These are called movies, films, or videos.

Light from an object, or subject, passes into the camera through one or more lenses. The lenses focus the light onto film stored in the camera. The chemically coated film reacts to the light and records an image, or picture, of the object. Photographers then remove the film from the camera. With special chemicals, they use the film to make prints of the image on paper.

A few months ago, I was assigned a task to find a way to scrap out LinkedIn connections data. Being a fresh graduate computer science student this was an exciting task for me since it was something kind of real project and not the boring practicals I did in my college days.

In 1837 a Frenchman, Louis Daguerre, found a way to record the images made by a camera obscura on metal plates. These pictures were called daguerreotypes. Around the same time an Englishman named William Henry Fox Talbot used a similar box to record images on paper. These men had created the first modern cameras.
