What is the Difference Between Compiling and Debugging?

Debugging:-Computer programmers, like everybody else, are not perfect. This means the programs they write sometimes have small errors, called “bugs,” in them. These bugs can be minor, such as not recognizing user input, or more serious, such as a memory leak that crashes the program. Before releasing their software to the public, programmers “debug” their programs, eliminating as many errors as possible. This debugging process often takes a long time, as fixing some errors may introduce others.

Compiling:-When programmers create software programs, they first write the program in source code, which is written in a specific programming language, such as C or Java. These source code files are saved in a text-based, human-readable format, which can be opened and edited by programmers. However, the source code cannot be run directly by the computer. In order for the code to be understood by the computer’s CPU, it must be compiled into an executable program.

Most software development programs include a compiler, which compiles source code files into machine code. This code, sometimes referred to as object code, can be executed directly by the computer’s processor. Therefore, the resulting application is often referred to as an executable file. Windows executable files have a .EXE file extension, while Mac OS X programs have .APP extension, which is often hidden.

So the conclusion is a compiled program may have errors or bugs but not a successfully debugged program cannot have any.

So for a perfect program you need to debug and compile a program… Read More

Machine Vision Systems: Basic Things to Know

A machine vision system is based on a technology that uses imaging-based inspection for a variety of applications like robot guidance, process control, and automatic inspection, just to name a few. Actually, machine vision involves a lot of technologies, expertise, methods, actions, integrated systems, hardware products, and software to name a few. Let’s find out more about it.

There is a difference between computer vision and machine vision. Basically, this system tries to create an integration between current technologies in fresh ways and implement them in order to resolve real world problems.

The machine vision process involves planning the project details and then finding solutions. And the process begins with imaging and moves towards the automated analysis of the required information like images.

Imaging based Inspection

Primarily, the visual inspection machines are used for image-based inspection and robot guidance. The first step involves the image acquisition, which is taken using lighting, lenses and cameras.

MV software programs are used in combination with digital image processing for the extraction of required information.


The typical parts of an automated inspection system include output devices, software, image processors, camera and lighting.


The imaging device can be part of the unit or may work independently. If it is part of the machine, it is known as the smart sensor or smart camera. When it’s used as a separate unit, the connection is made to the intermediate hardware, a frame grabber or a processing appliance.

Although traditional imaging is also used in machine vision systems, other alternatives are also quite common, such as x-ray imaging, 3D imaging, line scan imaging, hyper spectral imaging, and multispectral imaging.

While most of the visual inspection systems use 2D imaging, many of them also use 3D imaging. In fact, the 3D imaging-based systems are getting more popular with time. The most common 3D imaging method involves triangulation, which is based on scanning.

In this scanning, a laser is shot onto the object surface and seen from a quite different angle. Moreover, in the case of a visual inspection machine, you can achieve this through a scanning motion of the camera.

Lines from more than one scan are combined into a point cloud or depth map. In special cases, stereoscopic vision is implemented, especially when unique features are found in both views of cameras.

Other visual inspection systems are grid or time of light based. For instance, the grid array oriented system makes use of a pseudorandom structured system of light.

Image Processing

Once an image is captured, it goes through processing. Generally, the processing is done in more than one stages. Typically, the sequence starts with many tools like filters that change the image. After that, the extraction of data and objects is done. Next, the data is communicated and compared against different target values ​​for creating the desired results.

So, this was a brief introduction to machine vision systems aka visual inspection systems. If you are interested, you can install this system in your inspection rooms … Read More

The Importance of Blue Light Glasses for Kids

We are surrounded by blue light no matter where we go. This is the light that gives the blue color to the sky. The same light is emitted by the screens of the mobile phones and tablets when your kid plays his favorite games. Now, the question is, does this light cause harm to the eyes of your kids? Should you buy blue light glasses for your kids? We are going to answer these questions in this article. Read on to know more.

If you worry about the health of your kids, we suggest that you don’t allow them to use their smartphones all day. Instead, you should help them follow the popular 20/20 rule. This rule is quite simple and beneficial. Just ask your kids to look 20 feet away from the screen for at least 20 seconds after they have spent 10 minutes starring at their phone or tablet screens.

Another alternative is to buy protective glasses. They offer a great degree of protection. Plus, they don’t cost a lot of money.

In case you don’t know, blue light is a visible light that features shorter wavelengths and a high level of energy unlike other wavelengths. Given below are some common sources of this wavelength:

  • Sunlight

  • Smartphones, tablets and computer screens

  • TV screens

  • LED lights

  • Fluorescent lights

Although we don’t have strong evidence to suggest that this wavelength can cause damage to your kids’ eyes, we can’t take risk as there could be long-term side effects.

How do the Glasses offer Protection for their Eyes?

Spending a few minutes in the sun is healthy for your kids. As a matter of fact, a little bit of regular exposure to the sun can help your kids reduce their risk for developing myopia.

Although some sun is good for human eyes and body, excessive exposure may cause retinal damage over the long haul. According to research studies, kids are at a higher risk of retina damage due to constant exposure to blue light.

Moreover, prolonged exposure to this wavelength for years after years can cause visions problems after the age of 30. For instance, the exposure to UV light is associated with age-related macular degeneration. This condition may result in vision loss.

Screen Time for Children

Kids are more exposed to blue light when they are outside. However, if your kids spend most of their time looking at computer screens, they may suffer from digital eyestrain, aka computer vision syndrome. Given below are some common symptoms of this condition in kids:

  • Poor posture

  • Headaches

  • Fatigue

  • Eye tiredness

  • dry eyes

  • Vision changes

Aside from these, there are other risks of prolonged exposure to this type of light. Therefore, we suggest that you take proper measures to save the eyesight of your kids.

The Takeaway

If you are worried about your kids’ eyesight, we suggest that you buy them a good pair of blue light sunglasses. This is the only easiest way to ensure the safety of your kids’ health.… Read More
