Crypto-economics

What is cryptoeconomics? Ethereum developer Vlad Zamfir says that cryptoeconomics is:

Cryptoeconomics is a structured field of study that examines the protocols regulating the creation, allocation, and utilization of commodities and services within a decentralized digital economy. This practical discipline revolves around the crafting and analysis of these protocols.”

Cryptoeconomics originates from the fusion of two terms: Cryptography and Economics. Previously, the decentralized peer-to-peer system faced challenges. Torrent platforms have long utilized this approach for file sharing. However, this practice allowed anyone to share files within the decentralized network. When a file was downloaded, it was expected that the person reciprocated by sharing files with the network for others to access. This gave rise to an issue – individuals were reluctant to continuously share files, which needlessly occupied space on their computers. In 2008, a collective effort led by Satoshi Nakamoto introduced a paper that laid the groundwork for Bitcoin. This marked a pivotal point as it offered people a genuine economic incentive to adhere to the established rules.

Crypto-economics characteristics :

•  Built upon blockchain technology, each block within the chain incorporates the hash of its preceding block, forming an unbroken sequence.
• The specific transactional state is subject to alteration as transactions unfold.
• Immutability is a prerequisite for appending new blocks to the blockchain, ensuring that past blocks remain unaltered.
• The blockchain must be both downloadable and readily accessible globally, enabling verification of individual transactions from any location.

Cryptography

Cryptography, or cryptology in this context, involves the application and exploration of methods to safeguard communication from potential eavesdroppers, commonly referred to as adversaries. Bitcoin, on the other hand, represents a decentralized digital cryptocurrency – a type of electronic currency – enabling direct person-to-person transactions across the peer-to-peer bitcoin network, eliminating the requirement for intermediaries.

Bitcoin

Functioning as a virtual currency, the concept of Bitcoin was realized in 2008 through the manifesto of Satoshi Nakamoto. Distinguished as the pioneer blockchain implementation, it employs cryptographic measures to ensure the security of data within the ledgers. Many contemporary systems and applications derive inspiration from the Bitcoin framework.

Blockchain developers can be divided into two categories.

• Core blockchain developer
• Blockchain system developer.

The primary role of a core blockchain developer involves the conceptualization of the blockchain system’s structure, crafting intricate protocols, and devising security measures for the network. They bear the responsibility of overseeing the network’s operations comprehensively. In contrast, a blockchain system developer utilizes these established protocols and architecture to create decentralized applications that operate on blockchain technology. This encompasses tasks such as crafting Smart Contracts, designing interactive interfaces for Dapps (decentralized applications), handling backend development specific to blockchain, and ensuring the smooth operation of the entire technology stack supporting their Dapps.

Skills Required to become a Block Developer

Acombination of skills is expected by the person who aspires to become a blockchain developer. Let’s discuss them one by one.

Blockchain architecture

One must gain a deep understanding of the technology’s structure and become acquainted with concepts such as cryptographic hash functions, consensus mechanisms, and distributed ledger technology. A highly effective approach to achieve this is by studying the Bitcoin blockchain whitepaper.

Data structure

 The craftsmanship of architecture is coupled with the applied knowledge of data structure. The developer has to tune the data constantly to meet their personal requirements. A strong data structure added to the cryptography, builds a secure and immutable system.

Contractual development

 After the introduction of Ethereum, blockchains assimilate smart contractual functionality into its systems to apply business logics. It generally involves learning languages like Solidity Viper, Chaincode etc.

Web development

The most basic aspect of learning to be a blockchain developer is to get acquainted with the  basic designing of decentralized applications.

In summary, to succeed as a blockchain developer, you will need both technical and conceptual skills. Here’s what you need to master:

Technical Skills:

• Programming Languages: Solidity, JavaScript, Python, Go, Rust
• Blockchain Fundamentals: Hashing, blocks, consensus algorithms, forks
• Smart Contracts: Writing, testing, and deploying smart contracts (primarily on Ethereum)
• DApp Development: Using web3.js, ethers.js, React, or Vue.js
• Databases: Understanding distributed and traditional databases
• Cryptography: Public/private key encryption, hashing, digital signatures

Soft Skills:

• Logical thinking and problem-solving
• Continuous learning mindset
• Collaboration and communication

But even after knowing the main branches of this technology, how to work upon its practicality is a different thing.

Educational Pathways

While a computer science degree is beneficial, it’s not mandatory. Blockchain development is a field where skill and portfolio matter more than formal education.

Options Include:

• Degree Programs: Computer Science, Information Technology
• Online Courses: Platforms like Coursera, Udemy, edX
• Certifications: Vskills Certified Blockchain Developer, IBM Blockchain Foundation
• Bootcamps: Intense training programs with real-world projects

To bring this into practice, establish your own account on a cryptocurrency exchange platform. The process is straightforward, and you don’t have to create a comprehensive portfolio right away. You can start by gaining access to a platform like Coinbase and purchasing a few coins using a simple online wallet. This wallet allows you to access your funds from any server or device connected to the internet around the world. However, it’s advisable to store only the minimum amount needed for trading purposes, as your private key is stored on a separate server, which could attract hackers.

Cryptography:-

As previously explained, cryptography serves the purpose of safeguarding communication and preventing third-party intrusion. Blockchain, on the other hand, is established through the combination of data structure and cryptography. Possessing a profound mastery of this practice is crucial. It involves the process of converting original text into encrypted form, rendering the information resistant to manipulation. For blockchain developers, the skill of cryptography is essential in ensuring data protection. This artistry distinguishes blockchain technology from other contemporary innovations. Noteworthy cryptographic techniques include hash functions like SHA256 and KECCAK 256, which serve as prime examples.

Smart Contracts and Tools Required

For creating Dapps and contracts, one needs to get familiar with the existing Dapps. There are numerous applications developed every moment on Ethereum. The most popular Dapps are

Decentralized Exchanges (DEX) function as platforms where cryptocurrency trading takes place, mitigating the risk of exchange hacking and theft. Among the notable DEX options are Idex, alongside alternatives such as Bancor and the Token Store. Gaming Dapps provide a unique experience where users can acquire characters from creators, akin to traditional non-blockchain games. However, the distinction lies in the economic aspect, enabling players to freely trade characters with others. Cryptokittis stands as a prime illustration of a gaming Dapp. While the realm of Gambling Dapps has been marred by scams, some have garnered unfavorable reputation. For instance, fomo 3D serves as a cautionary example within this category. Ethereum’s marketplace applications are relatively uncommon, and Decentraland’s marketplace offers a splendid instance of such utilization.

Programming Skills

Blockchain also needs coding to work or even to exist as it has to be a transparent ledger holding on to it’s quality of being immutable and that’s what makes this technology credulous.

One of the coding languages extensively utilized in Blockchain development is one that you might be familiar with from your school days – C++. This assertion is substantiated by Bitcoin, where the core framework of bitcoin, known as bitcoin core, is implemented using C++. However, proficient developers must also embrace other programming languages to avoid limiting their skillset. Ethereum, for instance, employs a combination of various languages including C++, Ruby, Python, Java, Go, Rust, JavaScript, and more.

C++

Incorporating data and functions into ‘objects,’ C++ is a language that facilitates efficient resource management and provides enhanced memory control. C++ enables the development of applications capable of not only orchestrating interactions across multiple endpoints but also swiftly handling their exchanges. As an example, Solc, the compiler for the Solidity programming language, is coded in C++.

Java

Java has become one of the top 3 programming languages for blockchain development. Java programming language is useful in creating highly interactive web pages and making simple and immutable blockchains.

Python

The structure and rationale of this programming language for blockchain mirror the creator’s ambitious vision. To communicate with Ethereum clients, a Python version of web3 is employed, capable of generating abstractions (objects) dynamically to embody a smart contract.

Solidity

Solidity, a contract-based and high-level programming language for blockchain, is gaining traction as a newcomer in the field. An online Integrated Development Environment (IDE) called Remix is dedicated to crafting smart contracts using Solidity. Additionally, expertise in languages such as C++ and Java is crucial for blockchain developers to effectively encode and decode transparent data. These languages serve a dual purpose – not only are they instrumental in developing blockchain applications, but they also serve as a foundation for mastering contract-oriented languages like Simplicity or Solidity.

7. Adsense, PopAds, Infolinks
   Platforms like Adsense, Infolinks PopAds etc. have made marketing largely productive. Their engagement with Machine Learning makes the skill susceptible to the field.
8. Data, Intelligence, and Learning
   While Data Science remains as an overarching sphere that will remain in the field, Artificial Intelligence will become the focus. Multiple sectors will be affected by AI as it would become prominent in the market. Machine Learning and Natural language Processing along with AI will only expand.
9. Help Desk and Desktop Support Professionals 
   Most Businesses are customer facing and require the help desk. For the right customer service and troubleshooting, this job requires technical experience and soft skills for necessary results. Delivering of technology product and technology-enabled service need representatives with emotional intelligence.
10. Blockchain Developer
    Blockchain Developers are in demand because of the of the high impact of the technical skill in various industries. The skill set needed for becoming a blockchain developer would include an understanding of Blockchain systems in addition to possessing strong software development or engineering skills.
11. Software Testing
    Software Testing is basically the verification of the expected result of a Software System. What is emerging increasingly, however, is automated testing, the field has undergone advancement in such a way and the same would be expected of you.

Combining a Skill with a Personal Attribute

Skills like critical thinking, decision making, and vision are such that after an extent they need to be internalized by an individual, so much so, that they become natural to the individual. For example, if a game developer has emotional intelligence then it would be easy for her to understand the catch in a particular kind of game, the target audience and the possible reception of the game amongst the users.

Combining Skills with your Strengths

The choice of the skills you intend to learn this year must have some resonance with the field in which you have expertise. Forth, i,s, you can consider the interrelated skills. For instance, cloud computing, AWS architect, Machine learning and artificial intelligence are all interrelated in the work they are deployed in.

Time Period and relevance

It is true that skill learning is valuable if you are considering to switch your job or simply trying to undertake innovative and challenging tasks at work. However, you need to be conscious of the time it would take for you to learn and master a skill. Also how relevant would be the skill that you select today in your future? Some soft skills could be of such abstract nature that you can not determine the exact time it would take you to learn them with absolute conviction.

Making a better impression

It is true that employers are looking into these skills with great importance. But it is also true that employers cannot keep hiring experts with the undergoing changes. It then turns out that you need to upgrade your position before your employer. Things that can be done to stand out would include:

• Active participation in training programmes
  It is only through such training programmes that you can acquaint yourself with the priorities of your firm and acquire the skills that are in urgent need.
• Social media presence and web awareness
  No company can survive in the market if they do not endorse themselves in the social platforms. Being aware of the attractions and jargon of web is only favorable.

When a group of numbers is sorted in either ascending or descending order, the median is the midway value.

34. 2x + 3y = 10 and x – 2y = 4 must be solved.

2x – 4y = 8 is the result of multiplying the second equation by 2. x is removed by adding the two equations, leaving -y = 18. We discover y = -18 by dividing by -1. When y is substituted into the first equation, the answer to the x problem is 2x + 3(-18) = 10. To put it simply, x = 64/2 = 32.

35. What is the formula for a trapezoid’s area?

The area of a trapezoid is calculated as (total of bases) height / 2.

36. What is the equation for a rectangular prism’s surface area?

The formula for a rectangular prism’s surface area is 2 (length width + width height + height length).

37. What is the geometric mean?

The answer is that the geometric mean is the product of n numbers multiplied by n, where n is the total number of numbers.

38. Simplify: √81.

Answer: The square root of 81 is 9.

39. Solve: 2^x = 16.

Answer: Since 16 is equal to 2^4, the value of x is 4.

40. What is the formula for a parallelogram’s area?

The area of a parallelogram is calculated using the formula base height.

41. What is absolute value?

The magnitude or separation of a number from zero on a number line is known as absolute value. It is never negative.

42. Solve: 3x + 4 = 19.

If we take 4 out of both sides, we obtain 3x, which is 15. multiplying both sides by 3, x equals 5.

43. What is the equation for a rectangular prism’s volume?

The volume of a rectangular prism is calculated using the formula length, width, and height.

44. Explain mode.

The answer is that a collection of numbers’ mode is the value that appears the most frequently.

45. Solve: sin^2(x) + cos^2(x) = ?

According to the Pythagorean identity, sin^2(x) + cos^2(x) = 1.

46. If a train travels at 60 km/hr, how far will it travel in 3 hours?

Speed = 60 km/hr Time = 3 hours Distance = Speed * Time = 60 * 3 = 180 km

47. Find the simple interest on Rs. 5000 at the rate of 10% per annum for 2 years.

Principal (P) = Rs. 5000 Rate of interest (R) = 10% per annum Time (T) = 2 years Simple Interest (SI) = (P * R * T) / 100 = (5000 * 10 * 2) / 100 = Rs. 1000

48. If the ratio of boys to girls in a class is 3:2 and there are 15 boys, how many girls are there?

Let the number of girls be x. Ratio of boys to girls = 3:2 Therefore, 3/2 = 15/x Cross-multiplying, we get 3x = 30 So, x = 10 There are 10 girls in the class.

49. Find the average of the numbers 2, 4, 6, and 8.

Average = (Sum of numbers) / (Number of numbers) Average = (2 + 4 + 6 + 8) / 4 = 20 / 4 = 5

50. A shopkeeper bought a product for Rs. 200 and sold it for Rs. 250. What is the profit percentage?

Cost Price (CP) = Rs. 200 Selling Price (SP) = Rs. 250 Profit = SP – CP = 250 – 200 = Rs. 50 Profit percentage = (Profit / CP) * 100 = (50 / 200) * 100 = 25%

1. Introduction to programming using PYTHON.

2. Introduction to programming using JAVA. 

In the previous Section, I explained “How I benefitted through Introduction to Programming using PYTHON” course. Now I will share my views of my journey through Testpreptraining.ai with Introduction to programming using JAVA also!! 

You can access the Testpreptraining’s Test Series Content from this link: 

https://www.testpreptraining.ai/introduction-to-programming-using-java-98-388- certification-exam 

Before going to the topic, I will explain why I completed PYTHON, then to JAVA. Python has several Pros and very easier for beginner to start and enter into Competitive coding. 

Python is a popular, high-level, general purpose, dynamic programming language that has been present on the market for almost 30 years now. It can be easily found almost anywhere today: web and desktop apps, machine learning, network servers and many more. It’s used for small projects, but also by companies like Google, Facebook, Microsoft, Netflix, Dropbox, Mozilla or NASA. Python is becoming very popular in the world of programming. It’s growing faster than other languages, and it’s expected to become even more popular than Java in 2019. Job search engines also say that Python is one of the top three languages that can help you earn a good income. So, lots of programmers are learning and using Python.

Other Important advantages are: 

• It’s open source and has a lively community.
• It comes with a wide range of libraries.
• Perfect for making prototypes, allowing you to do a lot with less code.
• Has speed limitations.
• Faces challenges with threading.
• Not Native to Mobile Environment.

By considering all these benefits, I preferred Python to JAVA. Python coding is very useful to do projects in Machine Learning, AI and Data science. But java would be widely used in Embedded and Cross Platform applications. As I am studying M.Tech with Signal Processing as my specialization, I opted for Python. 

Then why we should learn JAVA? 

This is a perfect question for Java Lover. Java & Python both have secret magic, everyone is comparing both of them! 

Advantages of Java over Python: 

1. Java is Static type system and Python is Dynamic type system.J

2. Java is a better choice for cross platform support

3. Java is Faster than Python.

4. Java is Platform independent, python is not.

5. Java has support for concurrency and python is more resolutely a sequential  language.

6. Java is more verbose than Python.

7. Java is ideal for android and IoT development and Python is for Data Science (Mainly).

8. Java has Strong database connectivity on the other hand Python has weaker database access than java.

9. Java is in demand from last decades.

10. Java is compiled and Python is interpreted Language.

11. Today, 95 % of the enterprise are using Java and more than 1 billions Smart phone are having Java in them. 

The IDE support situation…This is most Important and we can say Prime comparision!! 

The strict typing makes it way easier to provide auto-completion for Java. 

For example, Let’s consider a sample code in Python… 

1. myVar = getRecord() 2. myVar.<lets autocomplete here> 

An IDE cannot reliably autocomplete the methods on myVar, because it does not, and cannot know what it is, as Python allows you to return anything (or nothing) from a method without declaring what that might be. 

Another example… In Python… 

1. if a == 1: 2. print “hmmm?” 3. if b == 2: 4. print “woop!” 

If I want my IDE to autoformat the above code, it can’t. Is the second “if” nested in the first? We can’t know, as Python doesn’t explicitly declare the end of scope. So the IDE can’t help you. In such cases, JAVA is quite preferrable

✓ Do you know about 5 Primary goals of JAVA? 

There were five primary goals in the creation of the Java language: 

1. It must be simple, object-oriented, and familiar.

2. It must be robust and secure.

3. It must be architecture-neutral and portable.

4. It must execute with high performance.

5. It must be interpreted, threaded, and dynamic. 

Besides Seeing the course videos, we should be able to code daily. In what view we should start our coding practice, to absorb the concepts systematically?? That’s should be taken take. 

You can access the TestPrepTraining.ai’s Test Series Content from this link: 

https://www.testpreptraining.ai/introduction-to-programming-using-java-98-388- certification-exam 

So we should opt for daily practicing of coding such that we will derive the new corners of the Programming Language. Not only JAVA, If choose C, Python… any Language needs good practice to cherish in it. While I was practicing, I found out few things which exclaimed me. They are all seems to be general for programmer, but those things were exclaimed me!! 

✓ Hello world Program 

The traditional Hello world program can be written in Java as: 

public class HelloWorldApp { 

public static void main(String[] args) { 

System.out.println(“Hello World!”); // Prints the string to the console. 

Every source file in Java should have the same name as the public class it contains, followed by “.java.” For instance, if it has a public class called “HelloWorldApp,” the file should be named “HelloWorldApp.java.”

Before you can run it, you must first turn it into bytecode using a Java compiler. This will create a file with the “.class” extension, like “HelloWorldApp.class.”

In a Java source file, you can have just one public class. However, you can have multiple classes with non-public access and any number of public inner classes. When your source file has multiple classes, one class must be declared public (using the “public” keyword), and the source file should be named after that public class.

A class that is not declared public may be stored in any .java file. The compiler will generate a class file for each class defined in the source file. The name of the class file is the name of the class, with .class appended. For class file generation, anonymous classes are treated as if their name were the concatenation of the name of their enclosing class, a $, and an integer. 

The keyword public denotes that a method can be called from code in other classes, or that a class may be used by classes outside the class hierarchy. The class hierarchy is related to the name of the directory in which the .java file is located. This is called an access level modifier. Other access level modifiers include the keywords private(a method that can only be accessed in the same class) and protected(which allows code from the same package to access). If a piece of code attempts to access private methods or protected methods, the JVM will throw a SecurityException 

The keyword static in front of a method indicates a static method, which is associated only with the class and not with any specific instance of that class. Only static methods can be invoked without a reference to an object. Static methods cannot access any class members that are not also static. Methods that are not designated static are instance methods and require a specific instance of a class to operate. 

The keyword void indicates that the main method does not return any value to the caller. If a Java program is to exit with an error code, it must call System.exit() explicitly. 

The method name main is not a keyword in the Java language. It is simply the name of the method the Java launcher calls to pass control to the program. Java classes that run in managed environments such as applets and Enterprise JavaBeans do not use or need a main() method. A Java program may contain multiple classes that have main methods, which means that the VM needs to be explicitly told which class to launch from. 

The main method in Java needs to take in an array of String objects. Usually, people call this array “args,” but you can use a different name if it follows the rules.

Starting from Java 5, the main method can also use something called “variable arguments.” Instead of just “String[] args,” you can write “String… args,” which means you can give the main method any number of String arguments. The result is the same as before (it’s still treated as an array of String objects), but it provides a different way to create and pass that array.

The Java launcher launches Java by loading a given class (specified on the command line or as an attribute in a JAR) and starting its public static void main(String[]) method. Stand-alone programs must declare this method explicitly. The String[] args parameter is 

Article on TestPrepTraining’s: Introduction to Programming Using JAVA – M.R.K.S.N.SAI 

The “main” method in Java takes an array of words or phrases called “arguments” that you pass to the class. These arguments are usually given through the command line when you run a Java program.

To display information on the screen in Java, we use something called “printing.” Java has a built-in way to do this using the “System” class, which has a special object called “out.” This “out” object belongs to the “PrintStream” class and has various methods for printing stuff on the screen. One common method is “println(String),” which not only displays the given text but also adds a new line afterward.

The string “Hello World!” is automatically converted to a String object by the compiler. 

This is the basic thing which I known in my initial days. Gradually, while I was keep on practising rigorously, I came to knew about the following things also… 

✓ Applet 

Java applets were programs that were embedded in other applications, typically in a Web page displayed in a web browser. The Java applet API is now deprecated since Java 8 in 2017. _{✓ Servlet} 

Java servlet technology provides Web developers with a simple, consistent mechanism for extending the functionality of a Web server and for accessing existing business systems. Servlets are server-side Java EE components that generate responses (typically HTML pages) to requests (typically HTTP requests) from clients. 

The Java servlet API has to some extent been superseded by two standard Java technologies for web services: 

• The Java API for RESTful Web Services (JAX-RS 2.0) useful for AJAX, JSON and REST services, and 

• The Java API for XML Web Services (JAX-WS) useful for SOAP Web Services. 

✓ JavaServer Pages 

JavaServer Pages (JSP) are like computer programs that run on a web server. They create web pages, usually in HTML, when someone asks for them through a web browser. JSPs mix regular HTML with special markers (<% and %>) to include Java code.

When you visit a JSP web page, it’s turned into a special kind of Java program called a servlet. This happens the first time you access it. Afterward, this servlet handles making the web page every time it’s requested.

✓ Swing application 

Swing is a tool that helps create the visual part of computer programs in Java. You can make it look like different styles, such as Windows, GTK+, or Motif. Sun, the company behind Java, offers these styles, and Apple has one called Aqua for Mac.

In older versions, Swing didn’t always look quite right on different systems. But in Java SE 6, they improved it by making it use the computer’s own way of drawing buttons and windows, which makes it fit in better with the rest of the system.

✓ JavaFX application 

JavaFX is a program for making desktop and web applications that can work on many different devices. It’s meant to take over from Swing, another program used for making the visual part of Java programs, but Swing will still be around for a while.

JavaFX works on Windows, Linux, and macOS, but it doesn’t try to copy the look of those systems exactly. Instead, it has its own style.

✓ Generics 

In 2004, generics were added to the Java language, as part of J2SE 5.0. Prior to the introduction of generics, each variable declaration had to be of a specific type. For container classes, for example, this is a problem because there is no easy way to create a container that accepts only specific types of objects. Either the container operates on all subtypes of a class or interface, usually Object, or a different container class has to be created for each contained class. Generics allow compile-time type checking without having to create many container classes, each containing almost identical code. In addition to enabling more efficient code, certain runtime exceptions are prevented from occurring, by issuing compile- time errors. If Java prevented all runtime type errors (ClassCastExceptions) from occurring, it would be type safe. 

The Java Class Library is the standard library, developed to support application development in Java. It is controlled by Oracle in cooperation with others through the Java Community Process program.^[69] Companies or individuals participating in this process can influence the design and development of the APIs. This process has been a subject of controversy during the 2010s.^[70] The class library contains features such as: 

• The core libraries, which include: 

o IO/NIO o Networking o Reflection o Concurrency o Generics o Scripting/Compiler 

o Functional programming (Lambda, Streaming) o Collection libraries that implement data structures such as lists, dictionaries, 

trees, sets, queues and double-ended queue, or stacks^[71] o XML Processing (Parsing, Transforming, Validating) libraries o Security^[72] o Internationalization and localization libraries^[73] 

• The integration libraries, which allow the application writer to communicate with external systems. These libraries include: 

o The Java Database Connectivity (JDBC) API for database access o Java Naming and Directory Interface (JNDI) for lookup and discovery o RMI and CORBA for distributed application development o JMX for managing and monitoring applications 

• User interface libraries, which include: 

o The (heavyweight, or native) Abstract Window Toolkit (AWT), which provides GUI components, the means for laying out those components and the means for handling events from those components o The (lightweight) Swing libraries, which are built on AWT but provide (non- 

native) implementations of the AWT widgetry o APIs for audio capture, processing, and playback o JavaFX 

• It’s a version of the Java virtual machine that runs Java programs and third-party apps, but it’s made specifically for a certain type of computer system.

• Plugins, which enable applets to be run in web browsers 

• Java Web Start, which allows Java applications to be efficiently distributed to end users across the Internet 

• Licensing and documentation 

✓ Implementations 

Oracle Corporation is the company that now owns and manages the official version of the Java SE platform. They got it when they bought Sun Microsystems in 2010. This version of Java is built on the original one made by Sun.

You can use Oracle’s Java on Microsoft Windows (it even works on older versions like XP, but they only officially support newer ones), macOS, Linux, and Solaris.

Since Java doesn’t have a formal standard accepted by big organizations like Ecma International, ISO/IEC, or ANSI, the Oracle version has become the widely accepted standard that most people use.

The Oracle implementation is packaged into two different distributions: The Java Runtime Environment (JRE) which contains the parts of the Java SE platform required to run Java programs and is intended for end users, and the Java Development Kit (JDK), which is intended for software developers and includes development tools such as the Java compiler, Javadoc, Jar, and a debugger. Oracle has also released GraalVM, a high performance Java dynamic compiler and interpreter. 

OpenJDK is another notable Java SE implementation that is licensed under the GNU GPL. The implementation started when Sun began releasing the Java source code under the GPL. As of Java SE 7, OpenJDK is the official Java reference implementation. 

The goal of Java is to make all implementations of Java compatible. Historically, Sun’s trademark license for usage of the Java brand insists that all implementations be compatible. This resulted in a legal dispute with Microsoft after Sun claimed that the Microsoft implementation did not support RMI or JNI and had added platform-specific features of their own. Sun sued in 1997, and, in 2001, won a settlement of US$20 million, as well as a court order enforcing the terms of the license from Sun.^[75] As a result, Microsoft no longer ships Java with Windows. 

Platform-independent Java is essential to Java EE, and an even more rigorous validation is required to certify an implementation. This environment enables portable server-side applications. 

✓ Use outside the Java platform 

The Java programming language requires the presence of a software platform in order for compiled programs to be executed. 

Oracle supplies the Java platform for use with Java. The Android SDK is an alternative software platform, used primarily for developing Android applications with its own GUI system. 

Android 

The Android operating system makes extensive use of Java-related technology. The Java language is a key pillar in Android, an open source mobile operating system. Although Android, built on the Linux kernel, is written largely in C, the Android SDK uses the Java language as the basis for Android applications but does not use any of its standard GUI, SE, ME or other established Java standards.^[76] The bytecode language supported by the Android SDK is incompatible with Java bytecode and runs on its own virtual machine, optimized for low-memory devices such as smartphones and tablet computers. Depending on the Android version, the bytecode is either interpreted by the Dalvik virtual machine or compiled into native code by the Android Runtime. 

Android does not provide the full Java SE standard library, although the Android SDK does include an independent implementation of a large subset of it. It supports Java 6 and some Java 7 features, offering an implementation compatible with the standard library (Apache Harmony). 

I would like to conclude with this quote… 

Truth can only be found in one place: the code. 

This line keeps motivating me, throughout my competitive coding journey!! 

Happy Coding ☺

1. JavaScript

JavaScript is the most popular, commonplace and a rather conventional programming language for all programmers. It is an object-oriented language that is deployed in front to end development and in the recent account back to end development as well. JavaScript is being brought to use in the Internet of Things (IoT) technology and game development. Due to its accessible UI, it is ideal for beginners. JavaScript besides the otherwise conventional HTML and CSS is useful in web tool technology. Due to its complaint and accepting syntax JavaScript is used for major websites like Amazon, Microsoft, Facebook, LinkedIn etc.

2. Python

Python has become an essential language for programmers with the advancements in AI, ML, Automation & Analytics. Python is most useful in software development, science and numeric purposes, ERP processes, game development, and data analytics. With the increased prioritization of automation, Python has gained immense demand. The development frameworks Django, Turbo Gear and Pyramid are python based.

3. Java

Java is and object-oriented programming language that deploys automatic memory allocation and garbage collection that makes it in effect easier to understand than C++. The language is compatible to be written on any possible device and in turn platform independent. The language can compile into low-level machine code that makes it flexible to be used on any device, so long as it is executed by JVM which is and acronym for Java Virtual Machine. JVM in itself however is platform dependent. Java is fundamental to the Android Operating system and accounts for various back end applications. The language is most useful for beginners due to its flexibility and business applications in abundance.

4. PHP

Hypertext preprocessors is a general purpose language. It is the most basic of programming languages that are used in creating web pages that are basically written in HTML.

GRE, that is , Graduate Record Examination, is a computer or paper based standardised test to apply for masters and doctoral degree programs in various universities in the United States. It is administered by the Educational Testing Service (ETS) and through verbal reasoning, quantitative reasoning, critical thinking and analytical writing skills, GRE sets a common eligibility criteria for the applicants of different educational and cultural background to applying for an advanced degree.
Apart from this general test of GRE, there is also a GRE subject test that evaluates candidate’s ability over particular subject and is required for getting admission in specialised courses, for instance, Mathematics, Literature , Physics, Psychology, Biology, Chemistry, and Biochemistry.

The GRE test is basically formed of three measures:

A. Analytical writing skills, that is, is to deal and support with any argument  accompanying evidence and discussion over certain ideas which requires a focused analysis of the given task.
 
B.Verbal reasoning skills, it reflects how one understands the content, captures the written material and compose the information from it. It requires the grasp of meaning and the analogy of words and concepts.

C. Quantitative reasoning skill is the practice of  dealing with mathematical concepts of algebra, geometry, arithmetic, data analysis. It  measures the  ability to analyse the problem and solving it through mathematical models.

The test is been taken in two ways
1. The COMPUTER-delivered:-
The criteria consists of six sections and the first section, always, is analytical writing task following by five sections coinciding two verbal reasoning sections,two quantitative reasoning sections and an experimental section. The examined person is given about 3 hours and 45 minutes for the entire testing procedure including a 1 minute break after each section and a 10 minutes break after the third section. The applicant is allowed to deal with the questions in any pattern within each section and can mark the question to review.

2. The PAPER-delivered:-
The format of paper based test is mostly similar to the computer based test except that it doesn’t include any experimental section.

PREPARATION for the GRE test-
ETS provides the resources for the preparation of GRE test through a preparation software, Power prep, that contains two practice tests of remote questions that gives an insight over the structure and scores of the actual GRE test . In addition, it supplies the review material as well for further practice. ETS is the only source of their retired material, denying any allowance to other companies.
University textbooks, GRE preparation books and online resources are much available if not interested in the online practice courses.

SCORES :-
• An analytical writing score reported on a 0-6 score scale, in half point increments.
•A verbal reasoning score reported on a 130 to 170 score scale, in 1-point increments.
•Scores:- A quantitative reasoning score reported on a 130 to 170 score scale, in 1-point increments.
               

Many factors affect the graduate school application and GRE score is just one aspect of the calculation of one’s profile. The undergraduate GPA, letters of recommendation (LoR), research, and personal essays will all contribute to the student’s acceptance into the desired universities.

Validity and Attempts to rise-
Despair is a natural tendency over the first failed attempt and  after months of labour and investing such load of expenses over it is dejection. But the spark of hope rises when one gets to know of the flexibility of attempts GRE allows . Technically there is no limitation for applying for the test but a gap of 21 days between consecutive tests is must with maximum of 5 attempts in a year.
And once the score report is in favour of the students, it’s validity consoles one’s heart for 5 years from the day score reports are published.

Talking about expenses, one needs to know that it’s not only GRE test fees but other expenditures as well that matters a lot and depends on  student to student.
It costs $195 for the registration of GRE. And this registration fee, initially varied for different countries but now is fixed for every student across the world by ETS. And it is just the initial stage of  spending, for after getting the score record of the test, one has to apply for their desired universities. ETS allows to send the score record to four universities for free and if the student decides to apply for more, it costs them 27 bucks per University. With this scale of expense, student need to shortlist the universities with great care.

Why GRE is a big deal?
After completing the graduation course, students plan to acquire a prestigious foreign degree through GRE .And an impressive GRE score, brightens the student’s profile with the exposure to international institutions. It reflects student’s analytical and reasoning skills related to the subject.

•A good GRE score paves the way of getting scholarships that makes the admission easier. Some universities mark GRE not for admission but for the selection of scholarship and fellowship candidates.

•A good GRE score helps to lift up the profile if the student has a week undergraduate GPA or little work experience.

• Different sections of GRE are taken into consideration for different programs. If the application of for maths or statistics program, the score of  Quantitative section are more effective than Verbal section. Similarly ,verbal and analytical section are considered more importantly when applied to English graduate program.

 So prepare yourself for this opportunity and give yourself some extra stars. *For further and detailed information regarding the GRE test, it’s official website https://www.ets.org/gre would be a great help.
