Some misconceptions about technology

Tech Blog: 

Should be charged with original charger -

Many people think that the phone should be charged only with the original charger available with the phone. Actually any charger can be charged with. One thing should be kept in mind that the charger will be used if its output voltage is similar to the output voltage of the original charger. There is no special reason. The same rules for any phone charger, laptop or power bank There will be no problem with the phone or its battery.

Impossible to get rid of deleted files -

Once a file is deleted from the computer or if a file is deleted from Recycle Bin, then it is not possible to get the file back. This is a concept but not completely true. After deleting the file, it remains there as long as the hard drive is not filled with anything else, or a new file will not be saved there, the deleted file will be there. It can be easily remodeled by any common Recovery software.

Apple Computer is not infected with viruses -

Many misconceptions are that Apple Computer is not infected with viruses. Actually Apple's computer is also infected by viruses. Apple's computer uses 1-2% of people and the remaining 98-99% people use Windows computers. The only difference is that the amount of Windows computer that is infected with the virus is not affected by Apple's computer. When a programmaker creates viruses on a platform where people use more. This does not mean that there is no virus in Apple.

Higher price means better HDMI cable -

The more expensive HDMI cable the picture quality can be found. Many people now use the HDMI cable to connect the TV with set-top boxes, DVD players or any other device. And many people think that the cable quality is as good as the quality of the image quality. In fact, the digital signal is transmitted through the HDMI cable. The signal will come through the cable or there will be no signal. It does not happen that the signal came but image quality is not good. Good cable is required only when the connection needs to be taken 20-25 meters away. Besides, work can also be continued with cable of 80-100 rupees. So with good image quality there is no relation to good HDMI cable.

More camera means more megapixel -

Today's latest misconceptions Many people think that the higher the megapixel camera means better image quality. But the word is not entirely true. The camera does not have to be more than just megapixels, with lens, sensor, aperture and image processing software as well as megapixel. Sometimes an 8-10 megapixel DSLR camera can take a lot of good quality pictures from a 20-megapixel phone camera. Only a camera's image quality can be judged based on megapixels.

Popular 5 language writing programs

Tech Blog: Information Technology Quickly Change In order to create new programs, the technology has to change and change with the era. What languages ​​are written in the program? The new version of all programming languages ​​comes regularly. But the popularity is not the same. Tamim Shahriar talks about five popular programming languages ​​that are useful for writing useful programs at this time

C. (C): Today 46 years ago C programming language was created by Dennis Ricchi, which quickly gained popularity. C is very powerful programming language. Many types of work can be done by C, one of which is the operating system created. At the university level, students of computer science are bound to be educated.

Currently, software is being used in computing the compiler, system programming and IOT (Internet of Things) programs. All students interested in computer science or computer science should learn c. Another programming language based on C-C Plus Plus (C ++) is quite popular.

Java: James Gosling created Java programming language in 1995. It is an Object Oriented Programming Language. Java became rapidly popular in creating desktop and web-based software. One of the reasons was that software created by Java could run on different operating systems. Initially Java is considered to be very slow programming language, but as a result of continuous development it is now popular as a very effective and powerful language. Java is widely used in developing enterprise applications. Zaav has also been selected to create native software (programs designed for specific operating systems or machines) for the Android operating system.

Javascript: JavaScript is the programming language of the internet. Initially, it was created for the browser, but it is now widely used both in frontend and backend. The programming language designed by Brandon Aich in 1995 has made it much easier to create interactive web applications. JavaScript can be created in a variety of programs with functional programming, object-oriented programming. Once again, the framework software programmers of different languages ​​of this language got popularity. In the hundreds of thousands of frameworks made on this language, Geekyri was popular for a long time. AngularJS, Reykjavit JS, Bhujes etc. The framework is popular in recent times. Server side JavaScript (such as nods) has also been popular in the backend. Javascript is also used in many frameworks to create mobile applications.

Python: Guido van Rozam created Python programming language in 1991. Python is an object-oriented programming language, but it is much easier than C ++ or Java. Python has a good reputation as a beautiful, straightforward and fluent language. As it is relatively easy to learn, so today Python is taught as the first programming language in many organizations. It is popular in the world of the web, as well as the most widely used programming language for machine learning and data analysis. So, the use of python is increasing in educational institutions, research institutions, software establishments everywhere.

PHP: In 1995, Rasmus Lerdrof created PHP programming language. This language has been created using C programming language. Web programming makes it a lot easier for PHP So, the language itself is popular, as well as taking web programming to more people. All of the popular software like WordPress, Joomla, Drupal are made with PHP. Therefore, it can be said, PHP is the most widely used programming language on the Web site. Although Python, Ruby and many other programming languages ​​are becoming popular in the web world, PHP still survives for a long time.

There are also: C-Sharp (#) is quite popular, especially for Microsoft's dot-net frameworks to be the first choice of most software manufacturers. Apart from this, three more programming languages ​​are fast becoming popular. These are Google's Go or Goals made in the backend of the Internet-based organization, Cotlin for the development of Android applications, Swift for the creation of Apple's iOS app.

The devices from far away will know about the heart

Tech Blog: Is human heart rate possible to be measured from a distance? For the benefit of modern technology many accomplishments are being accomplished. Recently Australian researchers created such a small drifting drone, which could measure the heart rate from a distance.

A group of researchers led by University of South Australia researcher Javan Chahal recently displayed the drone. Their claim, the drone is able to measure the heart rate of people from 60 meters away. This can be used during various human disasters.

The news agency Xinhua reported that the drone has a camera, through which the details of heart rate can be determined.

The researcher said that the newly developed drone can be used during any disaster. Usually during the disaster, the situation of the wounded people will be known by using the drone. In this software, the use of facial recognition will be used to measure heart rate. It is possible to know the heart rate of one hundred thousand people in one day.

The Australian Defense Force (ADF) helped the study.

However, researcher Chahal warned about the negative aspects of the drone. It may be suspected of spying, and even using it as weapons. Apart from this, mischief can occur if the information of such drone is lost to the miscreants. References: IANS
