I have given VI editor commands to use in Ubuntu operating system. You can practice using them for your benefit and you can complete your work quickly.

To begin changing or adding to text with vi, you can enter Insert or Replace modes, as shown in the following list. When you enter Insert or Replace mode, the characters you type will appear in the text document (as opposed to being interpreted as commands).
Ubuntu Vi editor commands Press the Esc key to exit to Normal mode after you are done inserting or replacing text.
List of VI Editor Commands.. i—Typed text appears before current character.

a—Typed text appears after current character.

o—Open a new line below current line to begin typing.

s—Erase current character and replace with new text.

c?—Replace ? with l, w, $, or c to change the current letter, word, end of line, or line.

Data science career these 4 top skills absolutely you need

The data science is a combination of technical and general skills. As a analyst you need to provide valuable information to the client. The below is highly useful list of skills.

Top Skills You Need for Data Science Career


data science

1# Paradigms and practices

This involves data scientists acquiring a grounding in core concepts of data science, analytics and data management. 

Data scientists should easily grasp the data science life cycle, know their typical roles and responsibilities in every phase and be able to work in teams and with business domain experts and stakeholders. 

Also, they should learn a standard approach for establishing, managing and operationalizing data science projects in the business.

2# Algorithms and modelling

Here are the areas with which data scientists must become familiar:
  • linear algebra, 
  • basic statistics, 
  • linear and logistic regression, 
  • data mining, 
  • predictive modeling, 
  • cluster analysis, 
  • association rules, 
  • market-basket analysis, 
  • decision trees, 
  • time-series analysis, 
  • forecasting, machine learning, 
  • Bayesian and Monte Carlo Statistics, 
  • matrix operations, 
  • sampling, 
  • text analytics, 
  • summarization, 
  • classification, 
  • primary components analysis, 
  • experimental design and unsupervised learning-constrained optimization.

3# Tools and platforms

Data scientists should master a basic group of modeling, development and visualization tools used on your data science projects, as well as the platforms used for storage, execution, integration and governance of big data in your organization.
Depending on your environment, and the extent to which data scientists work with both structured and unstructured data, this may involve some combination of : 

  • data warehousing, Hadoop, stream computing, NoSQL and other platforms. 
  • It will probably also entail providing instruction in MapReduce, R and other new open-source development languages in addition to SPSS, SAS and any other established tools.

4# Applications and outcomes

A major imperative for data scientists is to learn the chief business applications of data science in your organization, as well as ways to work best with subject-matter experts. 
  • In many companies, data science focuses on marketing, customer service, next-best offer and other customer-centric applications. 
  • Often, these applications require that data scientists know how to leverage customer data acquired from structured survey tools, sentiment analysis software, social media monitoring tools and other sources. 
  • Plus, every data scientist must understand the key business outcomes—such as maximizing customer lifetime value—that should be the focus of their modeling initiatives.

Data science Secrets Simple Project Useful for Practice

I want to share with you how to use Python for your Data science or analytics Projects. Many programmers struggle to learn Data science because they do not know where to start. You can get hands on if you start with a mini project.

I have used Ubuntu Operating System for this project Skills You Must Need to become a Data Scientist You need dual skills - Learning and Apply knowledge. In Data science you need to learn and apply your knowledge. After study engineering, any person getsB Tech or M Tech Degree. You can become a real engineer if you apply engineering principles. So Data science also the same.

Data Visualization in Python is my simple project Importance of Data Data is the precious resource in resolving Machine Learning and Data Science Problems. Define first what is your problem. Collect Data Wrangle  the Data and Clean it.Visualize the PatternsIn olden days you might be studied a subject called Statistical Analysis. In this subject, you need to study the actual problem an…

Top Solidity Interview Questions for Sure Success

Solidity is the prime language to write logic for smart contracts in Ethereum blockchain. These are selected interview questions refresh before you take any interview.

Interview Questions on Solidity1. What is Solidity?

A) Solidity is the main language that you can use to write programs in Blockchain, such as smart contracts.

2. Where the Solidity programs run in Ethereum?

A). Those will run in EVM. You can also call it as Ethereum virtual Machine.

3. What kind of logic a Smart Contract can contain?

A contract in the sense of Solidity is a collection of code (its functions) and data (itsstate) that resides at a specific address on the Ethereum blockchain

4). Can the source code of smart contract accessible to the outside world? 

A). No, it is not possible to access source code to the network. Also, there is a limited access to one smart contract logic to the other smart contract logic. Eve, file system and other processes cannot access the source code.

Actually the code is sand boxed an…

Automation developer these are top Skills you need to learn

Robotic process automation is an upcoming IT skill. Three tools are popular. It is difficult to learn all three tool. So, learn anyone tool to start your career in automation.
To get a job in this line, I found in my research that some programming skills and Hand-on training on any one of the tools is required. Also, try to know the differences between popular RPA tools.
Skills Companies Looking in Automation Engineers All big companies looking for candidates having experience in Automation anywhere, Blue Prism and UIPath. It is not possible to learn all tools. Learn anyone tool and do practice well.

Ok.

You may ask a question about how to do it. Join in good training institute and learn one tool.  Take online classes to learn faster.

8 Popular Encryption methods real Usage

Encryption works as it replaces original data with some special characters and stores the data. You need a private key to decrypt the data. Else it is not possible to understand encrypted data even for hackers.

Private keys are two types. Sender uses one private key and receiver uses one other private key.
I have given in this post about 8 encryption methods.

 Different Encryption Methods Classic CipherRandom Key GenerationRSA TokenHash FunctionsMac value - Message Authentication codeKey HashTLS ProtocolAuthenticated Cipher  1. Classic Cipher The best example is this kind of algorithm was used in world war -II communication machines. 2. Random Key Generations One kind of security. They use an algorithm that sends random numbers. People use that number as a password.
3. RSA Token Every 60 seconds a token is generated. Mostly people use for financial applications. An extra identity mechanism along with user id and password. 4. Hash Functions It assigns a hash va…

Three popular RPA tools functional differences

Robotic process automation is growing area and many IT developers across the board started up-skill in this popular area. I have written this post for the benefit of Software developers who are interested in RPA also called Robotic Process Automation.


In my previous post, I have described that total 12 tools are available in the market. Out of those 3 tools are most popular. Those are Automation anywhere, BluePrism and Uipath. Many programmers asked what are the differences between these tools. I have given differences of all these three RPA tools.

BluePrism Blue Prism has taken a simple concept, replicating user activity on the desktop, and made it enterprise strength. The technology is scalable, secure, resilient, and flexible and is supported by a comprehensive methodology, operational framework and provided as packaged software.The technology is developed and deployed within a “corridor of IT governance” and has sophisticated error handling and process modelling capabilities to ens…
