Programming

The demand for big data, analytics, and data science professionals is on a steady rise globally. Its relevance is increasing day by day in just about every sector. Not only IT companies, other sectors are also looking for data scientists. Major requirements coming from Financial Services firms, Retail and FMCG organizations, Investment/Retail Banks and NBFCs, Healthcare organizations, and Market Research firms. Companies are offering job roles like - Data scientist, Analyst manager, senior data analyst, Business analyst, Analyst consultant. 10 leading organizations with the most number of analytics opening this year are Amazon, Citi, HCL, Goldman Sachs, IBM, JPMorgan Chase, Accenture, KPMG, and E&Y & Capgemini. These companies are paying heavily for Data Scientist with proficiency in R-programming. Average pay scale is from Rs. 4-8 LPA. For Post-Graduates, it is even higher. It starts from Rs. 14-15 LPA.

Hello,
Assembly level Languages are low level programming language for microprocessors and other programmable devices. This isn't a single language, rather is a group of languages targeted towards a specific CPU architecture. It contains symbolic representation of the machine codes for the target CPU infrastructure. Unlike High - level programming languages like C+, Java, .NET, etc., these programs can be ported to only those systems which have the same CPU architecture.
Understanding of basic programming languages like GWBASIC, C, etc. would serve as an added benefit to understand Assembly level programming as these entire use top - down approach.
Though Assembly Languages are used these days only in companies which design microprocessors and other programmable devices, it does find an extensive opportunity in security devices, which involve output of hard-wired encrypted messages from those devices. Also, it does find massive employment in the field of Artificial Intelligence to design smart devices.

Ruby is a powerful, flexible programming language you can use in web/Internet development, to process text, to create games, and as part of the popular Ruby on Rails web framework. Ruby is a scripting language designed by Yukihiro Matsumoto, also known as Matz. It runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX. Ruby is a dynamic, reflective, object-oriented, general-purpose programming language.

1. You must know the object oriented programming principles.
2. You must know UML modeling.
3. Data structure knowledge is must before coding in any programming language.
Eligibility: Bachelor of Technology, Bachelor of Engineering, Bachelor of Science, Bachelor of Computer Application, Master of Technology, Master of Engineering, Master of Science and Master of Computer Application.
Admission process: If you are qualified just look for the right Institute and apply nothing fancy.

For a Java developer, having a strong understanding of Object-Oriented Programming is a must.
Master the core APIs- It doesn't matter how strong you are in terms of theoretical knowledge if you don't know the language constructs and core APIs.
Keep coding- Things look simpler when talking about them theoretically. We can give a solution to a problem very easy in theory. But we can realize the depth of the problem when we start implementing our approach. You will come to know the language limitations, or design best practices while coding. So keep coding.
Subscribe to forums -When starting to work on a new technology the best and first thing to do is subscribe to the relevant technology forums. Whatever the issue you are facing, someone else in the world might have already faced it earlier and might have found the solution. And it would be really really great if you can answer the questions asked by other forum users.
Read open source frameworks source code- A good developer will learn how to use a framework. But if you want to be an outstanding developer you should study the source code of various successful, popular frameworks where you can see the internal working mechanism of the framework and lot of best practices. It will help a lot in using the frameworks in a very effective way.
Know the technology trends- In the open source software development technology trends keep on changing.
Know different development methodologies- Nowadays choosing the development methodology depends on the client. Some clients prefer Agile and some clients are happy with waterfall model. So having an idea of various methodologies would be great.
J2EE would be a better choice as its an extended version. So, definitely opt for that.

Some questions for JAVA developers -
Which is the superclass of all classes?
Differentiate between J2SDK 1.5 and J2SDK 5.0?
What are wrapper classes?
What is the ThreadLocal class? How and why would you use it?
What is the volatile keyword? How and why would you use it?
What is runtime polymorphism or dynamic method dispatch?
What is the number of bits used to represent ASCII, Unicode, the UTF-16, and the UTF-8 characters?
Is it possible to import same package or class twice? Will the JVM load the package twice at runtime?
What is the difference between System.out, System.err, and System.in?
What is the Java Classloader? List and explain the purpose of the three types of class loaders?
What are the differences between Heap and Stack Memory?
What are the differences between Get and Post methods?
How do cookies work in Servlets?

Python is the older of the two languages. In programming language evolution, it is common to maintain backward compatibility indefinitely. This is not the case with Python. Python versions are largely compatible but have enough functionality- and syntax-breaking differences that they can be treated as different languages. Python is adapted because of Simplicity, Open source, object-oriented and General purpose language. It is an interpreted language available on many platforms, making it a portable option for general development.
Java on the other hand
Its attraction and value is its portability and relative efficiency. Java is a compiled language, unlike C/C+. Its execution model is more machine-centered than purely interpreted languages. Java is more than just a language and libraries. It is also a virtual machine and, therefore, an ecosystem. The Java Virtual Machine (JVM) is an idealized and portable platform for running Java code. Rather than worrying about hardware specifics and having to port code to new platforms, the promise of Java has been written once, run anywhere. That is so that as long as a JVM is present, anything compiled into its bytecode can run and interact easily with anything else written for the JVM.

Perl is a programming language developed by Larry Wall, specially designed for text processing. It stands for Practical Extraction and Report Language. It runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX. This tutorial provides a complete understanding of Perl. Prior knowledge of C/C++ or UNIX shell programming is preferred for Perl programming. Courses for Perl developers may include computer systems, algorithms, data structures, machine architecture, software engineering, linear algebra, and discrete math. Because Perl is a dynamic programming language that differs fundamentally from languages such as C/C++ and Java. There are many online courses available for Perl on Udemy, Lynda, Coursera etc. Check the below link for institutes offering Perl courses - https://www.shiksha.com/it-software/colleges/perl-colleges-india
