FIFA will track players’ bodies using AI to make offside calls at 2022 World Cup

FIFA, the international governing body of association football,* has announced it will use AI-powered cameras to help referees make offside calls at the 2022 World Cup.

The semi-automated system consists of a sensor in the ball that relays its position on the field 500 times a second, and 12 tracking cameras mounted underneath the roof of stadiums, which use machine learning to track 29 points in players’ bodies.

Software will combine this data to generate automated alerts when players commit offside offenses (that is: when they’re nearer to the other team’s goal than their second-last opponent and receiving the ball). Alerts will be sent to officials in a nearby control room, who will validate the decision and tell referees on the…

How to Become a Backend Developer

In the past few years, the internet has emerged as a powerful tool for the growth of every business worldwide. Applications are used all the time, whether studying, working, or watching a video on YouTube. YouTube is an application too. Right? No one can imagine their life without Apps because we constantly use them. Behind the scenes, any application relies on a large amount of code to function.

Web development combines two parts- frontend and backend, and both are of equal importance. The user interface connects the end-user with the internet and comes under the front end. The backend is all about the websites’ or apps’ functioning and structure. 

Backend development is basically like the BTS version of what happens on websites. Be it making purchases online or Email login, backend development is a necessity. Browsers connect with database information thanks to code developed by backend developers. 

Tasks regarding the job might be difficult to do at times, making work more stressful. Time is of the essence here, which sometimes wouldn’t be given enough, but the workload would still multiply. 

Above all, good communication, the ability to work independently or as part of a team, and perseverance are all qualities that should assist a backend engineer in creating trustworthy software. 

The Frontend and Backend are two different sorts of programming. The user sees the front, and the backend is what makes the frontend work.

So, let’s look at what backend developers are and the talents, income, and job responsibilities that come with being and becoming a backend developer. 

What is Backend Developer?

Let us understand this with an example. The website you are currently on, reading this post, is nothing but the frontend part of a website. All the buttons, including the sign-in button, images, and texts, together make up the interface of this website.

However, how can you view this web place in the first place? How do we get your information once you have signed in or signed up?

Well, that is because backend developers are working behind the scenes. The data taken from the signup form is stored in the organization’s database. Further, the organization can receive the data from the data set to send an email or recent update.

In simple terms, a backend developer is a server-side developer responsible for collecting, storing, and modifying data. If you are a beginner and want more information, you can go for Backend Development Bootcamp

Backend Developer – What Do They Do?

Backend developers must have technical expertise, analytical thinking, and excellent collaboration skills. As a backend web developer, you should be able to work independently to design the web infrastructure.

Here’s what many backend developers do on a day-to-day basis: 

  • Design and Build websites 

The major role of a backend developer is to build user-friendly applications or websites using efficient tools and skills. In addition, as a software developer, one has to develop complex MS SQL Server Databases, implement data storage, and keep an eye on the security of the application or website and user information. 

  • Write high-quality code 

Developers must write clean and easily maintainable code to produce sustainable web applications. Moreover, backend developers review the code, make changes, and conduct unit tests to improve the overall performance of a website.

  • Perform quality assurance (QA) testing

Create and oversee testing schedules to optimize user interface and experience, ensuring optimal display on various browsers and devices. 

  • Assess efficiency and speed 

Once a website is up and running and during updates and edits, developers need to assess its performance and scalability, adjusting code as necessary. 

  • Troubleshoot and debug 

Troubleshoot and resolve issues while communicating them to project managers, stakeholders, and QA teams. 

  • Train and support 

Maintain workflows with client teams to ensure ongoing support and lead training and mentorship for junior developers. 

How to Become a Backend Developer?

Acquire the Necessary Skills 

As the backend developers will be dealing with programming and codes, it is a must to learn about programming languages and be an expert in backend frameworks. This helps to make the work easier. As there are many programming languages, let’s talk about some languages widely used in backend development. 

1. Python

Python is intuitive and clear; subsequently, it can be user-friendly and easy to learn for beginners. Python consists of numerous deep learning libraries, making it the default AI language. The flexibility and versatility of the Python backend makes tasks easier and choose to best for Data Science. Everyone must have heard the name python in two ways, either as a snake or as the programming language. It is one of the fast-growing languages among languages. Easy syntax and fewer lines of code make Python a competitive advantage over other languages. 

2. Java

Java is most attentive to security which plays a major role in maintaining confidentiality while dealing with sensitive data. Due to the higher degree of scalability that it ensures, it is one of the popular choices for creating large-scale machine learning systems. Java is one of the most relevant programming languages used by backend developers. Product company websites mainly use it. The backend of Java is versatile, and developers can run code on any device, from laptops to smartphones. 

3. Statistical Programming Language

R is one of the top-most widely used tools for statistical calculations, mathematical modeling, and data visualization. R is an open-source platform, a powerful scripting language that deals with complex data sets, including computing and graphics. 

4. SQL (Structure Query Language)

SQL consists of crucial requirement tools that comply with the workflow of Data Science. Direct access to data is possible due to its combination of transactional and analytical capabilities. 

5. MATLAB (Matrix Laboratory)

MATLAB is highly supportive of workloads on numerical computations on a large scale. MATLAB consists of integration features and an interactive environment to build custom GUIs(Graphical User Interface). 

6. SAS (Statistical Analysis Software)

SAS, previously “Statistical Analysis System,” is a 4th generation programming language (4GL) and a statistical software suite from SAS Institute. SAS plays a significant role in retrieving, reporting, and analyzing statistical data. 

7. Scala

Scala is highly capable of handling parallel processes on big data arrays due to the combinational feature of functional and object-oriented programming. Moreover, Scala comprises libraries suitable for data science tasks and developmental process that enhances flexibility. 

8. Julia

Julia is highly effective for data analysis as it consists of dynamic tools and speed enough to meet modeling requirements in an interactive language. As a result, Julia is one of the top choices among high-profile businesses focusing on time-series analysis, risk analysis, and space mission planning.

9. TensorFlow

TensorFlow is an ML-based framework that is used to handle a large volume of datasets. TensorFlow works efficiently with distributed computing and can quickly train complex and large neural networks. TensorFlow includes creating dataflow graphs and structures describing how data moves through a series of processing nodes. 

10. JavaScript

JavaScript is one of the easy object-oriented languages most widely utilized for web development programming due to its capability to build interactive web pages. JavaScript is more of an aid in data science for creating visualizations, which is an excellent way of evaluating and extracting big data. JavaScript backend is a highly beneficial language in web development as it can be used in both frontend and backend development. This is a highly recommended programming language if you focus on being a full-stack developer rather than a backend developer. 

These are some programming languages. The next skill is to manage how to handle API 

(Application Program Interface). This is a bridge layer between two applications. It accepts incoming requests to a backend application, retrieves the relevant data, and returns it in a response message. Developers use API to fetch data for applications. These are some of the skills you should learn to be a beginner in the field of backend development. 

Get a Relevant Degree 

There is no specific degree for backend developers. In India, most highly skilled backend developers either have a B.Tech degree in Computer Science or a diploma in computer science.

To pursue a B.Tech degree in computer science, one must complete their 12th grade with at least 50% marks in physics, chemistry, and math as major subjects. For a diploma degree in computer science, one can take it after the 10th, which will be a three-year program. However, students can also opt for a diploma program two years after their 12th in science.

However, one doesn’t need to have these degrees in hand to become a backend developer. Therefore, even if you have already completed your graduation with other degrees irrelevant to this field, you can still be a skilled backend developer by pursuing some of the courses offered specifically in this domain.

Get Relevant Certifications

There are several certifications out there for backend developers. If you haven’t pursued a computer science degree, you can take an In-person Backend development certification course or an online certification course.

In-person Backend development certification course: 

To find the best in-person certification course, one has to do extensive research and consider several factors, including the duration of the course, fees, lessons covered, etc.

In-person courses or boot camps are costly, but as compared to pursuing a degree, it is quite less. The main advantage is that one can have one-on-one conversations with your instructor.

Online Certification course for backend 

It is not as easy to find back-end-only online courses. Most teach full-stack, which is both the front and backend. However, there are several benefits of taking a Back-End Development Bootcamp that provides certification.

The first is that you can learn from the comfort of your home. The second being one can access the lectures of the classes for a lifetime. Anytime you have got any doubts, you can straight away look into the lectures.

Moreover, these web development certificates online offer optimized learning lectures that let you grasp concepts easily.
