To generate a stable income, an educational web platform must be able to meet competition. Firstly, it should offer some obvious benefits to users. Secondly, it needs to have perfect usability. Finally, it must be easy to maintain and upgrade, as this will help you keep up with the latest trends. 

Developing an effective e-Learning website from scratch is quite a challenging issue, so you need a skilled and experienced software development team to fulfill it. In this guide, we’ll make a brief overview of educational platform types, their basic features, and models of generating revenue.

What Type of Educational Platform to Choose?

Arguably, the most popular concept of an online educational service is a kind of marketplace where one can buy various courses. Your platform can be field-specific (e.g. courses for web developers) or multi-discipline. The content can be delivered to clients in various forms: lectures, slide decks, e-books, audio/video classes, etc. As a rule, e-courses include tools for self-assessment and testing. 

Among other things, you need to create a transparent system of certification. Once a user has completed the course, he should get a certificate confirming his competence.

Typical Revenue Models of e-Learning Websites

Before developing an e-Learning platform, you need to make sure you understand how the whole system will work and how exactly you will gain a profit from it. To get some ideas, you may review some existing models that have already proved their effectiveness. In our guide, we’ll compare two giants of the online education sector – Coursera and Udemy.

Coursera is (probably) the best-known online platform that collaborates with numerous universities all over the globe. The educational institutions provide video records of lectures on multiple disciplines. Coursera, in turn, provides access to the lectures for a moderate monthly fee of $39-79. The total number of courses available is about 2700.

Udemy’s killer feature is an impressive variety of courses. Unlike Coursera, it collaborates not only with world-famous universities but also with individuals. If a newly added course meets certain quality control standards, it becomes available to customers. There is no monthly fee; instead, users pay for every course. The price per course varies from$20 to $200.

Basic Features of an Online Educational Platform

While e-Learning websites do not come equal, some essential features are mandatory for all types of educational platforms. One should keep in mind that a good educational site is rather complicated. It must be developed by a high-skilled and competent team. Alternatively, you may choose to outsource website development. In many cases, it helps run the budget. Let’s find out what features are essential for an e-Learning site, irrespective of its type.

A Sign-Up/Login Page

Before you start using the service, you must sign up or log in by entering his username/email and password. The good idea is to add such features as two-step authentication and social network integration. The “Forget the Password” feature is a must-have.

User Profile

On this page, users will specify their personal info, such as first/last name, date of birth, gender, occupation, contact information, and so on. 

Search Page

A user must be able to find the needed course quickly and with minimum hassle. Apart from a standard search box, you may want to add a drop-down menu for choosing a category, search filters that help narrow the search, the system of suggestions, and the query history. 

Course Description Page

Each course must have a short description, which includes the topics covered, the number of lessons, and basic information about the tutor or educational institution. Additionally, you may add the “Testimonials” option to let users share their opinions on the courses completed.

Instructor Dashboard

Instructors should have access to advanced settings of their profiles. Thus, apart from adding personal info, they must be able to monitor their statistics, upload and edit files, including videos, slides, presentations, etc.

Payment Page

Decide what types of payments you are going to accept and add integration with the relevant payment systems – MasterCard, Visa, PayPal, or any others. It’s crucial to use modern security protocols for transaction processing. 

Push Notifications

While not mandatory, this feature is nice to have. Push notifications are a modern and convenient method of delivering important information (tests completed, deadlines, adding new courses, etc.). However, avoid being obtrusive with too many notifications.

Admin panel

As the name implies, this is a page for an administrator who manages the whole service. Depending on the specific features of the platform, an administrator may have various powers: user ban/unban, content editing, adding, deleting, etc.

Once all the essential pages are created, and all the features added the project can be released for initial testing and bug-fixing.

Roles and Responsibilities

Frontend developers aim to ensure that the user-side is delivered. But what should Angular dev do, and what are they responsible for? You’ll find the answers in the section below.

Angular Developer Role

Angular developers focus on creating interactive User interface service, ensuring outstanding performance across all platforms. 

Angular stands for JS framework utilized to create scalable web apps. It’s a collection of well-integrated libraries that cover a bunch of features. 

Front-end engineers need to be also proficient in other software development tools along with Angular language. 

Angular is primarily used to develop one-page apps, and it utilizes HTML’s syntax to express your app’s elements clearly. This framework enables you to build your own custom components that can pack functionality and render logic into reusable pieces. Moreover, Angular allows you to effortlessly move your data from your Javascript code to the view and react to user events without writing any code by yourself. 

Angular Developer Responsibilities

Angular developers are quite diversified specialists. Apart from front-end development, they’re responsible for bug testing, API integration, database management, and so on.

Fast front-end creation. Capability to build scalable, dynamic, and cost-effective web and mobile apps, particularly one-page applications. Moreover, the Angular framework applies multiple out-of-the-box components, which reduce the development time. Their main goal is to develop high-efficiency software.

Deal with JavaScript, HTML, CSS Angular UI developers should write logical JavaScript code while applying HTML and CSS languages.

Designing. Capability to create minimalist web app modern design applying latest techniques and approaches.

RESTful APIs creation. Capability to interpret the API documentation and employ it efficiently. It’s vital to ensure smooth communication with backend services. 

Testing. Angular devs are also in control of conducting three different tests to ensure the application works as expected. Some of them are unit testing, integration testing, and end-to-end testing.

External data sources and APIs. Angular UI developers should be proficient in external databases and APIs implementation when necessary to obtain the information from 3-party services.

Bug fixing. Angular engineers should keep up with modern Angular libraries releases and upgrade them regularly to fix defects detected in previous versions.

Things to Know Before Finding Angular Developer

It’s vital to know about requirements before hiring an Angular programmer. You can’t just message the potential candidates, tell them that you need a front end developer, and share a link to a job site. Most likely, they don’t accept your job offer. All specialists appreciate their time. Any developers will wait for a detailed and strict description of their project’s responsibilities. Hence, you’ll need to draw up the list of requirements, define the deadlines by which the project should be completed, and what tech stack should be applied during product development.

Angular developer skills

Angularjs developers’ skills vary depending on the qualification level: junior, middle, or senior. 

Basic skills:

• Great understanding of typescript languages like JavaScript, HTML5, and CSS to build light-weight and well-optimized code
• Be familiar with Angular best practices and modules.
• Creating independent, testable modules
• Experience working with AJAX and DOM manipulation techniques
• Capability to write a cross-browser compatible code
• Deep knowledge of REST services
• Enhanced understanding of database, web APIs, and other web services employed in the system

Middle and senior skills:

• Expert-level of the Angular framework. As this framework is regularly upgraded and renewed versions are released, it’s vital to sustain the required knowledge and skills.
• Proficiency in web markup, mainly understanding of HTML and CSS. A programmer who knows how to employ web markup has a correct understanding of all correlation elements, including UX principles.
• Monitoring how users interact with the software on the client-side of the software and giving conscious feedback.
• Ability to write asynchronous code, utilizing state-of-the-art techniques such as RxJs Observables, if it’s required
• Writing complete unit tests employing automated Test Driven Development tasks.
• Hands-on experience with RESTful API integration applying HTTP queries to receive, deploy and delete information.

This is not a complete list of required skills. For example, you may need a specialist who has a deep knowledge of Typescript functionalities, browser APIs, or REST architecture. The final choice will depend on the complexity of the project. 

Interview Questions 

I covered basic interview questions that can assist you in evaluating the candidate’s level of experience. 

Hard Skills Questions

• What is the use of Angular?
• What is data binding in  AngularJS?
• What are the controllers in Angular?
• What stands behind Angular directives?
• What are the different types of Angular directives? 
• Explain the importance of the NPM and Node_Modules folder.
• What is Typescript, and why do we need it?
• Explain the architecture of Angular.
• Explain the significance of Components and Modules
• What is the Package.json file in Angular, and why is it essential?
• What do Annotations and MetaData mean?

The question set can differ depending on the project’s requirement and individual approach.

Soft Skills Questions

Soft skills questions vary depending on corporate culture and are usually adapted to personal preferences. 

• Detail orientation 
• Communication skills
• Change management capabilities
• Creativity
• Problem-solving
• Ability to teamwork

Of course, these questions don’t guarantee a successful interview if you don’t have a technical background. But they aid you in finding the right AngularJS developers. In the section below, I disclosed the different cooperation models.

Hiring Options 

The IT market provides you with several hiring options to find Angular programmers with the skill set needed to inject life into your project concept.

You can start negotiating with independent contractors, augment your in-house team, or hire specialists from outsourcing organizations.  

Freelancers

Freelancers work remotely as independent contractors. You can use different freelance platforms to find the appropriate front end expert. You can talk with the candidate via the live video call to access their skill level and understand whether you’re both comfortable with each other.  

If you need to build an enterprise-level app, it’s better to skip this option. This approach works great for small projects and simple applications. Mind that one freelancer can’t create top-tier software all alone. You may need to form a dedicated team, including designers, front-end developers, solution architects, and others. 

However, hiring a team of freelancers can be a costly and risky idea due to team fragmentation. Besides, all the responsibilities for the project management lay on your shoulders (in case you don’t have a project manager).

Pros

• Freelancers charge less than a software development company
• Good for small-one tasks

Cons

• Impossible to check the product’s quality if you’re not a tech specialist
• Can abandon your project any time
• One freelancer can’t be in charge of the entire software development life cycle 
• Risks of deadline failure

Below you’ll see public services for finding Angular developers:

• Toptal
• Upwork
• Stack Overflow
• Angular Air

In-house Team

Looking for in-house Angular developers implies a long and tiring recruitment process that requires interviewing each candidate independently.  However, they’ll build software under the same roof, and you’ll have a high level of control. If you’re a startup, hiring local experts is recommended to establish a consistent and effective communication process. You can also cooperate with offshore programmers, but you should be ready to handle time zone and language differences. The in-house team is a convenient but costly approach. It’s associated with additional expenses like office rent, equipment, software, taxes, and so on.

Pros

• Complete control over the development process
• You can enhance communication between employees during the development
• No language issues

Cons

• Overpriced service. You’re charged to pay monthly wages taking no discern of an employee’s project contribution.
• Additional expenses.
• Difficult hiring process. You’ll need to recruit each applicant separately.

You can look for full-time employees on the following platforms:

• Indeed
• CareerBuilder
• Glassdoor

Outsourcing Agencies

Outsourcing development overseas can save you hundreds of dollars as this option doesn’t require additional expenses like rent, taxes, or equipment.

How does it work? You outsource product development to popular tech hubs like Poland, Ukraine, or Germany and cooperate with a dedicated team experienced working on various industry-specific projects. Or you can extend your in-house team with one specialist (e.g., Angularjs developer)

The main benefit of outsourcing companies is that they’re responsible for team management and project delivery. You just need to take care of money. The point is to find a reliable vendor meeting your resources and requirements. 

Pros

• Cost control. The outsourcing model doesn’t require additional expenses like rent or software. Besides, you get a custom project estimate before the project deployment.
• Diversified talent pool. You can select a competent developer from a wide variety of professionals experienced in front-end web app development with Angular.  
• Cost optimization. You can attract experienced developers globally without losing quality. Angular developers’ rates can vary depending on the country.
• Flexibility. If the product requires some changes, the team can be scaled up or down to meet changing project requirements. 
• Quality. Building up expertise in multiple fields allows outsourcing agencies to deliver high-quality products within an established timeline.

Cons

• You may encounter communication issues and language barriers
• Different time zones. It’s better to select the country with slight time differences.

I’ve compiled a list of platforms to look for outsourcing companies: 

• Clutch
• GoodFirms
• IT Firms

You can select the right vendor based on its cases, review, and clients’ feedback. Thus, you’ll get a sound understanding of what skill set your project requires, what budgetary provision should be set aside, and what software development companies meet your initial requirements. 

Wrapping Up

Finding a competent developer is challenging no matter what type of specialist you need. As a business owner, you’re responsible for the consequences of choosing and delivering a high-end product for your clients. Thus, it’s essential to consider all the nuances to hire a programmer fitting your business needs and requirements.

In the first stage, text becomes part of the infrastructure. They occupy a central place in people’s lives. Text has been used as a tool to create laws and develop strategies. This is especially true of land laws, which began to take the form of written texts instead of personal testimonies.

In the second stage, text became an integral part of everyday life. Thanks to massive literacy campaigns beginning in the nineteenth century, most people mastered the skills of writing and reading. Literacy helped access information in newspapers with descriptions of events, in pamphlets with recommendations for farmers, and in bills to keep track of debts. The more people mastered reading and writing skills, the more mainstream literacy had to become.

Computers first became part of the infrastructure when the government used them for the census. Universities, airlines, and banking started using computers in the 1950s. Around the 1980s, computers became available to most people, and knowledge about computers began to spread from the knowledge fields of narrow specialists into the lives of ordinary people. People were more likely to use computers when contacting hospitals, organizing government data and managing education.

Then computers became part of life. The ability to write a simple program or code gradually became a basic skill. Programming and computational thinking are empowering and become a requirement for anyone from a physicist to a journalist. The ability to read and understand computer code is becoming more in demand, so programming is moving from special knowledge to universal literacy. It is the literacy of using modern tools of communication and work – computers. And if this is an aspect of literacy, it needs to be developed from childhood

How programming teaches problem solving

Programming develops computational thinking. It is a set of techniques for solving problems in computer science, but applicable in any field. For example, computational science helps in education. A special platform collects data about students’ activities. With the data, the instructor tracks ineffective assignments to create a new curriculum.

Computational thinking teaches how to formulate a problem, look for a solution, and analyze it. Programming is part of computational thinking and the most effective way to master it. For example, before programming, we analyze and break down the problem into subtasks. Programming concretizes computational thinking and can be a tool for gaining knowledge.

Why teach children to program

Constructivist pedagogical ideologist Jean Piaget proposed this idea: children learn faster when they form their own ideas about what they see and draw their own conclusions, not when they are told how they should perceive the world. Children are not passive recipients of knowledge, but on the contrary, they construct it themselves.

Programmer and one of the founders of artificial intelligence theory Seymour Peypert added: Effective learning occurs when a student creates an object that is meaningful to him, whether it is a sand castle or a theory. Constructionism combines two types of construction: children construct things in the real world and construct new ideas in their heads. The two types of construction create a continuous spiral of learning: when children have new ideas, they construct new things in the real world. Programming helps children bring these ideas to life.

Through programming, a child develops computational thinking. Computational thinking helps children develop problem solving skills, creative thinking, learning skills, and teamwork skills.

Develops problem-solving skills
Programming and computational thinking help children learn networking skills: chatting, video conferencing, and social networking. When solving complex problems, children use the four basic components of computational thinking: decomposition, pattern selection, automation, and abstraction.

Teaching children programming is not about making them programmers in the future. The task of programming is to prepare children for computational thinking, which will help them confidently cope with the complex problems of the 21st century, which have no one-size-fits-all solution.

How to Teach Children to Program.

According to research on the development of computer thinking, a formal setting develops systematic thinking and approaches, while an informal setting helps children develop motivation and identify areas of interest. The ideal setting should combine both. The proliferation of technology is blurring the lines between formal and informal education. Teachers no longer need to “skim through” all educational programs – students are building new connections to the world on their own.

Professors Kafai and Burke created two learning environments to assess the differences between structured learning and extracurricular environments. In each, students created digital stories with the same teacher for ten weeks.

According to the study, in the after-school environment, fewer children completed their projects, but made them more complex and larger. Students in the club used more creative programming skills and were twice as likely to collaborate with their peers. That said, for those just getting acquainted with programming, a structured class would be more effective.

With regular slots, you simply place a bet and then pull a knob or press a button to start spinning. If they stop on a winning combination, you win some money. A winning combination can be three of the same item, such as three cherries or three diamonds. Regardless of what is on the reels and what the machine shows, there are potential winning combinations. There is no involvement of another player, you just have to wait to see where the reels stop. Then the process starts all over again.

There are some similarities with online machines, but there is also a difference. You place a bet and pull the knob to make the reels spin. Now you have to see if you get a winning combination just like you do on regular machines. Or you can try again to take a chance by making the next bet.

The really big difference you see with fruit machines is what’s called a “trope.” It’s kind of like a board game. So you can spin the reel and it will land on a symbol that will leave a trail on the screen. Different things can happen to you here, depending on which fruit machine you play. There may also be a small wheel on the screen that you have to activate. It will land on a number that you will move to that certain number on the screen. Whatever square you land on may have some sort of bonus attached to it. This may tell you that you have three extra free moves. So this means that for the next three times you spin the reels, you no longer have to pay to do so. But if you win, you can keep your winnings. In many ways, playing fruit machines means that you get more options for your bet. This is one of the reasons why they are so popular.

How to learn casino insider secrets in slot machines when playing fruit machines

Slot machines are pretty simple when it comes to the standard old type machines that first came out. They were those machines where you had 3 reels that spun and you had to line up bells or cherries. Although they still have the classic 3 tumbler slots, they have come a long way since then. Now they have a lot more pictures and a lot more flashing lights. There are more combinations to win.

How much to bet is determined as the machine itself requires. It can be a quarter bet. This means you can only bet 25 rubles or some machines can allow a maximum bet of seventy-five cents. If you pay seventy-five cents, you get the maximum payout when you win. So you can choose how much you want to bet. The choice of bet is up to you.

Some of the new machines have bonuses attached to them. For example, if you manage to line up certain images, you will be rewarded with a certain number of free spins. Or, you might get a bonus package that you can choose for yourself. More often than not, slot machine games contain all sorts of graphics to make the game interesting and entice more people to play it.

Many touches on the theme of the machines. Whenever a new Talk Show comes out, it is worth waiting for a similar version of the slot machine. Slot machines based on this system are considered more appealing to people because they are already familiar with the concept of the game. Fastest withdrawal online casinos in Canada are here.

Whether you can strategically plan for winnings or it’s all a matter of chance, slot machines are very entertaining and intriguing.

The main things to know about how slot machines work
First is that a slot machine is a machine. If you ever see a slot machine from the inside, you will understand how simple this machine is. You just have to understand the technique of how the machine works. A whole bunch of wires, electronic things, lots of gadgets and a motherboard that holds the random number generator (RNG) computer chip(s).

Most modern slot machines are designed to look and feel like the old mechanical models, but they work on a completely different principle. The outcome of each pull of the knob or push of the twist button is actually programmed by a computer or random number generator (RNG) inside the machine

• Client/ Server Computing

Client/ Server computing happens when the client’s computer connects with one or more server computers in a network. As a result, a client can request a resource from the server. Clients and servers also communicate through a computer network. This happens when the server hosts several programs to share with the clients. Therefore, it is the client who initiates a conversation with the server.

The client-server model operates in a request-response messaging pattern. It should follow the set standard communication protocol. There are rules, dialog patterns, and language to follow when requesting a server’s service. Some major applications that use client-server interfaces include World Wide Web, Email, and network printing.

Besides, in client-server computing, the server can only host a limited number of users at a time. As a result, the server can only respond to some clients each time.

Types of Client-Server Computing

• One-Tier Architecture

It involves placing all the components required for a software application in a single server. As a result, all the application’s elements such as interface, back-end data, and Middleware are in one place. Therefore, it is direct and straightforward to use a one-tier interface.

• Two-Tier Architecture

The two-tier architecture consists of the server, client, and the protocol. This interlinks the two. The domain logic is on the server host while the Graphical User Interface (GUI) code resides on the client’s host. The GUI comes in languages such as Java and C++.

• Three-Tier Interface

It has three tiers, which are the presentation tier, application tier, and data tier. A prominent example of a three-tier interface is Microsoft MySQL Server. It has a protocol layer, a relational engine, and a storage engine.

The presentation or user tier is the user interface layer where multiple views of a database can be made available by the application. The application tier is the service layer that does detailed processing. It sits at the middle of the system and acts as the mediator between the database and the end-user. Finally, the data tier carries the database server that keeps information.

• N-Tier

N-tier can be open or closed. In a closed N-tier interface, a layer can only communicate with the next layer down. Within an open one, a layer can communicate with any layer under it.

The interface separates an application into two, that is the logical layers and physical tiers. The logical layer controls dependency and separates responsibilities in an application. The physical tier adds a delay of data from additional network communication. It also promotes scalability.

• Packet Switching

Packet switching involves grouping of data into blocks known as packets. It routes them through a network using a destination address in each packet. It allows many users to share the same path in a network. Also each packet can take a different route to its destination. Besides, it is a connectionless network.

The Process of Packet Switching

Each pocket in apacket switching technique contains a header, payload, and a footer. The header carries two network addresses of the packet. One for the host (sender) and the second for the receiver. The intermediate routers use them to direct the packet to its correct destination. On the other hand, the payload contains the actual data.

When does a packet get transmitted? When a packet is available in a node, it is sent depending on its header information. Also, the packets of a particular message are not routed on the same path. Therefore, an order takes place for the packets in a message to reach the destination. It is the work of the destination to reorder the packets.

Besides, the packet may contain additional information such as;

• Error handling- Packets carry parity bits or checksum to detect any error during the transmission process.

• Hop counts- this is where a packet gets ‘time to live’ information. The value of the hop counts continues to decrease as the packet passes through the network node. The system discards the packet when the hop counts reach zero. This repeats when the packet fails to reach the destination. ‘Time to live’ helps to avoid congestion in a network with faulty packets that may lead to failure.

• Priority- priority helps to transmit packets in a particular order. Once a network incorporates a QoS (Quality of Service), packets queue in a specific order.

• Length- some packets contain the length field. It indicates the quantity of the packet.

• TCP/IP Connectivity

TCP/IP stands for Transmission Control Protocol/Internet Protocol. It was invented in the early 1970s. It supported the U.S. Department of Defense Advanced Research Project Agency (DARPA). The department helped scientists transmit data to different computers in distant places in the world.

TCP/IP is a global set of methods that governs how to break and group digital messages into packets. It routes them into the right addresses. After routing it reassembles them into coherent messages. The IP contains the address to which the data is sent, while the TCP caters for the data delivery.

ATCP/IP divides different communication tasks into layers. Each layer has its functions to cater for. The data passes through various layers before reaching its destination. Once the data is delivered, TCP/IP goes through the layers in reserve. it does this in order to reassemble the data and give it to the recipient.

The Four Layers of the TCP/IP Model

• Datalink Layer

It is also referred to as the physical/link/network interface layer. It handles the physical parts of sending and receiving data. This is through a wireless network, device driver, or internet channel.

• Internet Layer

The Internet layer or the network layer manages packets’ movement. The packets move from one point of the internet to another.

• Transport Layer

It gives reliable data connection between two devices. The transport layer breaks the data into packets. It then recognizes its packet from the other devices. Also, it ensures that the other device has acknowledged the packet it receives.

• Application Layer

The application layer is the group of applications that need network communication. It is what the user interacts with, for example, email and messaging.

The three technologies which the internet is based on are crucial for every network. They work together to offer smooth communication processes. The server and the user are able to reach each other well. Thus make sure your network hosts the three technologies in the best suitable manner.

Source Code and Object Code

Source code comprises statements made in programming languages. With the help of visual programming tools or text editors and saved in files.

Object code is an output or a compiled file. It is obtained when a programmer uses a C compiler to compile the source code.

The object code comprises sequences of machine-readable instructions. The instructions need to be processed by the central processing unit (CPU) of a computer. App software and operating systems are, thus, in the form of object code.

Source code refers to as the “before” version of compiled computer programs. While object code refers to the “after” version of the same.

In the case of script languages like JavaScript, code exists in only one form. Either there is no object code and source code.

How Source Code Originated

Tracing the origins of source code is difficult. Programmers of the early forties wrote the first software in binary code. One may consider these early programs as the first examples of source code.

Computer engineer Tom Kilburn wrote one of the first examples of source code in 1948. He saved it on his computer in the digital format. The purpose of this program was to solve a mathematical problem.

In the fifties and the sixties, some companies wrote software programs. But the companies provided their source code free of cost. As software companies continued to evolve, the demand for source code increased. Source code used to be published in popular computing magazines. This was before the emergence of the Internet. Those interested had to retype this code if they wanted to use it.

Later, programmers started saving source code in floppy disks and sharing it with one another. When the Internet arrived, source code became easier to access.

Open Source Code vs. Proprietary Source Code

Two types of source code are available—open-source code and proprietary source code. Check the licensing agreement to find out more about the nature of the source code.

Proprietary Source Code – The source code of complex software programs is proprietary. Like that of Microsoft. When you buy the source code from Microsoft, you can access only the compiled executable files. It comes along with their associated library files.

Proprietary software companies like Microsoft don’t reveal their source code to customers. They do this to safeguard their intellectual property. Also, they don’t want customers to make changes to the source code. Some source code may either destroy the program or make it insecure.

Open Source Code – Apache OpenOffice is an open-source software code. Programmers can download and change it.

The purpose of open-source software is to avail the source code to talented programmers and developers. This way they can work on the code and change it to enhance the program. This makes it more secure and robust or even changes it into something better.

If you are a programmer, you can download and use open-source code bearing public licenses. A good case is the GNU General Public License.

Source Code Structure

The structure of the source code depends on the traditions of the language written in. As most programming languages relate to one another. The following elements are common to source codes written in all languages.

Commands – All software programs need instructions that establish their purpose, goal, or intent. These commands either display text messages or trigger calculations.

Comparisons – Most software programs comprise building blocks of queries. This comes on the basis principles of propositional logic. Entering a particular value, thus, triggers only one solution and not any other.

Variables – These are information-packed vacancies. They appear throughout the source code under assigned names.

Comments – Programmers using common programming languages comment on lines between the code. This allows programmers who access the code in the future to understand parts of it better.

Loops – This is repeating commands to reach a particular value. In a source code, a query can form the foundation of a loop.

The purpose of creating source code is to solve a problem. But there are different ways of solving the same problem. For example, two programmers may work on finding a solution to the same problem. Using the same programming language, can produce source code that doesn’t look alike.

All good software programs, however, avoid introducing unnecessary text. They are aware that unnecessary text complicates the problem further. Even experienced programmers find it difficult to read complicated code. This is referred to as “spaghetti code” because its structure is complex and tangled.

Website Source Code

The term “source code” is also used to refer to the structure of websites. Though it is a document written in HTML language and not a software program or app. You may also come across statements in programming languages like JavaScript in website source code. Source codes of software programs as well as website source codes are saved as simple text files.

Studying the source code of a website and detecting faulty elements in it can be an interesting exercise. All web browsers allow you to access and study website source code. You can download and save the website source code as an HTML file. You can then open it in Notepad.

You can view the website source code without downloading and saving it. Web browsers allow you to view the source code in two ways, as follows:

View HTML Code – This looks like the downloaded file. When you choose this option, a page displaying the source code opens in a new tab.

View HTML Code with Analysis Tool. This option presents an exciting way to explore the website source code. You will find the analysis tool under “Inspect” (Google Chrome). You can also find Inspect Element” (Firefox and Internet Explorer) in the context menu.

This option displays the source code along with many interesting functions. For example, you can place your mouse pointer over a line of code. Then find out exactly which part of the website the code affects.

Uses of Source Code

Source code has many uses, as follows:

• It forms the foundation of a software program.

• Skilled programmers can access it to customize a program whenever required.

• Developers can change the source code to make the same program work on other platforms.

• Shared source code facilitates growth and learning within the developer community. Also leads to the creation of new applications.

Coding is computer programming, which allows the writing of programs to develop software, or a web page, for example, but also to tell a machine what to do, to guide it. What for? Because we would like this info page to open when we click there, when the text appears on a pink background, that the machine directs the water jet pressure as it takes to cut a piece of metal, etc . . The purposes can be very diverse but the code is the initial language necessary for these uses.

The real French word is “programmer.” “Coder” comes from English and is more and more used.

Geek Anecdote: Know that when a programmer writes lines of code, he says, in his flowery vocabulary, that he “pees lines of code.

For those who are not immersed in body and soul computing, the code is a mystery. Better yet, we don’t even know it exists. And, honestly, we don’t care. I hope it works.

One thing is certain: this will be essential for tomorrow’s trades.

What’s the point of learning in the classroom?

There is not just one but lots. The student will discover how to create small action scenes himself with his tablet or computer. This will mobilize another form of intelligence since he must design, anticipate, program the movements of characters on the screen. Thus, he will solve the problems that arise to him and take care of the architecture of the program, its design, while creating the story he wants to tell.

Programming a story and moving the actors on the screen will help him develop sequencing abilities, which the student also uses in reading: spotting the beginning, the middle, the end of action, a scene described, and programming it in a logical order.

The student mobilizes all this when he does write production: At the beginning … [blah, blah, blah…]; then… [blah, blah, blah…]; then… [blah, blah, blah…]; for finally … [blah, blah, blah…].

Rather than having a long suite of “and, after,” “and after,” “and after” …

Having to arrange a character’s actions in a coherent and logical way will develop structuring abilities of thought. In this way, he will be better able to structure his production of writings later, so that it flows from the source and to convince his audience. If we go through winding paths and not very logical, we quickly lose the attention of others.

Encode the movements of these little “men” and different characters, make them speak at the right time, position the “blocks” appropriately will help children to realize the importance of this structuring, of this logic.

With the ScratchJr app, programming is learned by ordering action blocks: If the “blue guy” says “Thank you, well, well, and you?” before the “cat” has had time to greet him and ask him how he is doing, it’s messy. And when it’s messy on the screen, you realize it by watching the action and you’re going to fix it by reorganizing the blocks logically. This will not necessarily be obvious in a text written by the child.

With pure coding tools (see Code Academy or Free Code Camp), we see the immediate effects of what we order to “the machine” and it’s amazing … or very annoying if something gets stuck… but you also learn to look for mistakes. We are forced to start again until we get the desired effect. The approximation is not allowed. We need precision.

Programming offers the opportunity to make mistakes and correct mistakes – which is too rarely the case in school: you test, it works or not, you start over. We are only sanctioned by the success of the project or the fiasco. No sentence from above. The trial-and-error is very formative.

Programming serves language but also mathematics. We will repeat actions a number of times, for example, which requires numbering capabilities.

It can be said that with applications of this type, students do not only learn to code, but they will code their learning.

School workshops are being held. What if we were inspired by it?

You’ve heard of it: the coding-testers, Magic Makers. These magical names make you dream because they make reason the possibility of creating their own games. There’s something to “show off” in the playground.

I was lucky enough to attend a code session at Magic Makers, which was founded by Claude Térosier and Sébastien Louit.

They’re using Scratch. Students aged 8 and over had been taking part in the course since the beginning of September and we’re all creating their maze full of pitfalls, traps, holes to be bypassed, etc… to play it afterward. Or playing the boys.

The skills and sensibilities of each one come to light: one will work on the design, while the other will make a very elaborate journey. We don’t all have the same talents but everyone can prioritize what they like. It’s his game and he’ll meet the audience who will be sensitive to it.

One of the great characteristics of group coding is the cooperation that emerges from it: “Are you stuck? I know how to help you. I’m taking the time to guide you.”

A final argument if you are not already convinced: we do not know today what the professions of tomorrow will be, the ones that our students will practice. The only certainty is that systems programming, coding, will be necessary for this world of the future. And who will be able to use this language will hold the keys.

Trades of the Future

The trades of the future? We don’t even know their names. Knowing that, according to a study by the University of Oxford (09/13), in 20 years, 50% of the trades will be replaced by the machine, in the US, one imagines that the other half will have to reinvent itself. But in what? A lead for digital, perhaps? Today, an “ethical hacker” (paid hackers to test software) earns between $100,000 and 125,000 (The Guardians US Survey – 07/14). And it’s not about to falter.

Similarly, in September 2014, 8 times as many students as in 2002 chose the Computer Science Class at Harvard. In 2013, Xavier Niel created School 42, which recruits without a diploma, offers a program-learning course without a theoretical course or a teacher, at the end of which each student can draw between 30 job offers or about… without holding a recognized state diploma. It’s a dream, isn’t it?

Only one thing is certain: since it is better to know how to work wood to become a cabinetmaker, knowing how to code in a world cemented by the digital will be an asset, to master the “machine” and not the other way around. It won’t necessarily make the difference – like speaking English today – but not mastering the language at least will certainly be a disadvantage. There is already an explosion in the number of “coding” courses, and this is not about to falter. The future of our children is encoded now.

Today, onboard computing is everywhere. The automobile is one of the sectors that use a lot of onboard technologies. This profession, which mixes pure and hard computing (programming, application design) and electronics (sensors, interfaces, etc…), is shown as a profession of the future in the field of new technologies.

A quick overview of embedded systems on cars

Evolution and origin….

It was at the end of the 1980s that we started talking about microcontrollers in cars. Since then, their number has only increased, bringing to the passing technologies developed specifically for the automobile such as the CAN network.

What about today?

Electronics account for 30% of the price of the vehicle, there are on average between 40 and 60 computer controllers in cars and up to 80 for high-end models. Contrary to all that one might think, there is not only one computer box controller but several, scattered in the vehicle.

Technology, Electronic, Micro-controllers

These are mainly programmable microcontrollers (mostly in the C language). They are designed to take up minimal space, release little heat and consume as little energy as possible.

Sensors

In a car, you can find just about every type of sensor you can imagine, ranging from the simple temperature sensor to the tachometer (turn count) through the light sensor, rain, etc.

The transport of information

For a long time, the lengths of wires unrolled in cars are impressive and necessarily expensive (about 800 meters of cables). Since the late 1990s, networks have appeared in our cars. The CAN and LIN networks are mainly found. The goal is to connect all the calculators on a single loop and have them communicate together. For the record, the networks are sized so as to be occupied only 20% of the time.

Computer science, Real-time notion

Real-time means adding a notion of execution time to a task. On your Windows PC, running time will only affect your good mood. In your car, the reaction time between the moment you press the brake and the time your wheels are slowed down could affect your life.

Each task has a time limit that it must not exceed. For example, between the time you press the horn button and the sound of the noise, there may be a maximum of 30ms (PSA).

Programming

Everything is developed on computers and models. To compile the code, the principle of cross-compilation is used. It’s about compiling software for a platform other than the one used for development.

Most microcontrollers are equipped with an interface called JTAG (Joint Test Action Group). This interface is used to code components but also for debugging. From this port and specific software, the technician can know exactly what is going on in the microcontroller, run the software step by step, put stopping points, etc.

The benefits

Cars have always been safer thanks to safety equipment that implements on-board systems such as ABS or ESP. The comfort of the occupants has also improved considerably. In garages also electronics are useful: by plugging in a computer, the mechanic can directly know where the mechanical problem comes from.

The downsides

All of these types of equipment are expensive, complex and like any complex element, the risk of bugs is high. Electricity consumption is not negligible, it is even one of the main limits today (the Citroen C4, in a high-end model, has 2 batteries). Computer boxes are so everywhere… that there is soon no more room to put in!

Becoming an auto-reprogrammer

Automotive reprogramming has many advantages, and it is a growing activity: zoom in on to this profitable automotive business, engine reprogramming training, and the necessary skills. This type of job is new and rewarding as not many people are doing it yet.

Automotive reprogrammer, a new and still unknown trade

In this growing sector, there is no reference degree training yet: CAP, Bac Pro, BTS… That’s why many people who have downloaded software can now position themselves in this niche… often with mixed or sometimes even damaging results for their customers. Reprogramming an engine is a complex job, which is not improvised and requires great technicality: it is, therefore, better to start by finding the right training!

Before you start: the basics of the trade

Before embarking on this sector, it is better to have a certain technical background, a knowledge of the principles of the operation of a thermal engine, and a logical mind.

But there is no need to be an engine engineer: graduates of the BTS MCI (Internal Combustion Engines), experienced professionals in the automotive sector (engine preparer, garage owners,…), or any professional (or passionate!) of automotive mechanics can take our training and become a reprogrammer.

Engine reprogrammer: opportunities

Once the training is completed, the re-programmer can set up his business or work for a mechanical professional, and specialize in a specific sector: the automobile, in competition or not, the heavy goods vehicles, on which there is a strong demand from the transport companies or the agricultural sector which is also dynamic. There is also a growing demand for reprogramming related to the E85 conversion of gasoline engines.

Reprogramming is a skill that opens doors: today, more and more automotive maintenance professionals are offering this service to their customers, and are looking for qualified and trained employees. Become a professional in engine development by taking our training.

If,  however, you are a software developer, you can apply as a lead programmer at automotive manufacturers.

Well, what program coding languages and skills should we attain to be successful in web development? Most experts in this area say it depends on many factors. When it comes to selecting the perfect IT-language for site construction, it is important to understand that there is no such word as “perfect” in terms of data processing. It’s just a matter of selecting the language that highly responds to your needs. Before you decide what language is appropriate for you, it would be smart to consider the following issues:

1. server platform; 
2. server software;
3. previous experience in programming;
4. back-end database.

Before choosing a specific programming language, consider the above-mentioned server platform, software part, coding experience as well as a server database. Taking these conditions into account, you won’t have trouble selecting the proper language in a particular case. We are not going to describe HTML, CSS since these languages or at least their basics should be known by any web developer. Even if you don’t, it’ll be too easy to learn them any time. TOP-8 most popular computer languages for web engineering are shown below.

JavaScript

JavaScript is an utterly marketable and powerful computer coding language intended for website construction. It is extremely useful as this language can help us create a conversation for our website. JavaScript is capable of performing a great many functions including browser control, editing content in the data storage. It’s also ideal for customer-side scripting and communicating with users, as well as asynchronous data exchange.

PHP

We can talk a lot about PHP and its functional purpose, but the main thing is that it’s designed for server-side programming. It means that its library is tuned for those constant tasks that you perform many times. PHP has the advantage of intertwining with HTML code, allowing you to work with the layout while programming. PHP compatible with most operating systems and especially with Unix and Windows. 

Professional programmers use it on the back end of the server, considering PHP as the most suitable language for web designing. Basically, it can be embedded in HTML descriptor language and further, structure fluctuating pages. If the task is to extend the web application, then the best solution is to use PHP language. You don’t even have to use an external file: PHP code penetrates the HTML encryption.

Python

Talking about high-end scripting dialects, then Python is what fits the description. It was created to solve a back part of a server transcribing tasks. The language’s suitable for both websites and smartphone Apps. Python copies coding paradigms like structured coding. In addition to the structure, we can remind of operational programming and it’s also the merit of Python. It works confidently on a Windows server, although the original purpose used to be exceptionally for LINUX.

Ruby

Ruby is known to be a highly recognizable and temporal coding language for website development. It is used to configure or program mobile Apps and websites. This language is efficiently balanced and accessible with a help of practical programming. Ruby is favored by many IT experts because of its uncomplicated and impactful processes, writing and is a very easy-to-learn language for newcomers.

Java

The Java language is basically meant for creating mobile Apps and network programs. It is considered the main code language for Android. Java keeps up with the times and today is more up to date than ever. It includes object-oriented programming (OOP) – a technique for simplifying intricate code, in which a piece of code with conflicting functions is divided into independent objects, each of which contains the same functions and data. The functions are activated while directly referring to them, rather than simultaneously, creating a conflict. Additional Java benefits:

1. security;
2. reliability;
3. simple syntax.

C

C is a consistent program coding language developed in the early 1970s by Dennis Ritchie. It is intended for use in the Unix operating system. Since then, it has spread to many other operating systems and came to be a broadly used computer language. C is respected for its effectiveness and claims to be number one in popularity. With its help, programmers easily perform software system shorthand, although it is also used for App transcribing. C is a useful language as it demonstrates a similar syntax that is used by many modern languages: Java, PHP, JavaScript.

Perl

Perl is an adapted scripting language that is compiled into binary implementable low-level code. Perl is a vastly recognized program writing language in the sphere of web designing. Perl presents essential tools for resolving various unspecified failures in the system programming. Nowadays, Perl is actively used while writing interactive Apps, administering servers and is adapted to all popular platforms such as Windows, Mac, and others.

SQL

SQL, in other words sounds like Structured Query Language. SQL is an indispensable part of web construction. If a site designer uses such databases as Microsoft SQL, Oracle, MySQL, then he is supposed to know about this language and be able to use it. But SQL has a few disadvantages. First of all, its complexity. The language was conceived as a means of end-user experience, but became so complicated that it turned into a tool for professional programmers. Any specialist must certainly know SQL if he runs such databases as MySQL, Oracle in development. 

The task of any programming language is to describe the content of a page in an accessible way.

What Means a Good Web Designing Team?

If you decide to create your own business on the Internet, then it is important to find the right contingent from the very beginning and separate it from the bad agencies. Unstable web agencies are often seen in the poor quality code and design, inappropriate solutions, overdue deadlines, and too high projects’ cost. Working with such a team, you run the risk of not only disrupting the deadline for a project, but also get a low-quality product at the end, which will result in a loss of time and budget.

Why Do People Face Problems in Finding an E-commerce Team?

The difficulty is in the fact that there are too many web development organizations on the market. In most cases, each e-commerce agency concentrates on a definite platform or a certain e-commerce solution. They all offer different web development services aimed at different types of businesses. But how can we choose the team we really need?  First of all, we must understand what kind of service is needed. Thus, will narrow the field of our searches and increase the chances of finding the right technology partner. Right now, we are going to tell you about the characterization of IT teams based on the types of their services and projects they provide to clients.

Templates

Basically, a template is a collection of HTML web pages.  In addition, you can fill it with appropriate text or images, which will result in a finished website.  Mostly HTML is used to create such sites, but sometimes CSS is suitable as well.  Such sites will allow you to create an online store without the help of developers and designers.  As for the developers, they are actively using this method for creating websites and online stores.

Templates allow creating a simple website for your business that will be visible to search engines. For instance, WordPress Platform and template designs bought from marketplaces like Theme-Forest, Template-Monster, or Elegant Themes came to be the most popular way to create a template site. 

Unique websites

Some web development companies specialize in creating unique websites. They start building a website from scratch, according to customer requirements. The design process becomes much more complex as it involves researching the target audience and developing exclusive features. To create a unique website, one needs a significant budget and quite a lot of time.  However, an exclusive website is a great solution for well-known brands and large companies that want to surprise their customers with an unusual design.

Online Stores

E-commerce sites make it possible to sell products and services on the Internet. The online store can work both on an existing or on a custom-made platform. In the IT services market, companies that specialize only in creating online stores are called e-commerce agencies. Usually, such companies have extensive experience in the areas of e-commerce platforms, payment gateways, and other solutions related to online commerce. An online store may include both standard functions, such as a goods basket, catalog, payment gateway, and more complex integrations with CRM, social networks and shopping websites. 

Full-cycle Development Companies

Full-cycle development companies consist of several departments, due to which they provide a wide range of services. Typically, such companies have the development section, design, management, and testing department. Thus, they create not only websites, but also design, mobile applications, and exclusive functions with further website support. Cooperating with such a company, a customer receives an all-inclusive package. It is more convenient for future website owners to work with such a team than control the work processes of freelancers. Working with a full-cycle team is not affordable for everyone, but it justified by lots of commercial means.

How to Choose a Web Development Team

Choosing the right development team is not as easy as it seems. We can even compare developing a website to building a house. If you hire unskilled foundation workers who will use the wrong materials, then your project will be at risk. To avoid such situations in the development of your website, we’ll share the most important aspects, taking which into account, you will find the trustworthy team. The steps are as following:

Mind the team’s Portfolio

While choosing your future development team, it would be reasonable to assess the expertise level. It’ll let you understand whether the team has enough experience to complete your project. Therefore, the first step is to look at your future team’s portfolio. In most cases, you will be able to assess the level of functionality and usability of ready-made websites, as well as their programming and design skills. The agency’s portfolio may include projects that suit the level of your requirements and expectations. Moreover, you will learn more about the company’s experience in a specific area.

Request Contacts of Previous Customers

All existing companies have their history and previous clients. You can ask their contacts to communicate with them directly. If previous customers are happy with your future team, then you are in good hands. If not, it is better to look for another command. A short interview with previous clients will let you know more about the development team.
