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.

r—Replace current character with the next one you type.

Poor Data Quality-New Job Roles in Data Quality

Data quality is on rise and important to the organizations today. Since in Experian research it has found that poor data quality causing losses to the companies.

Experian research suggests companies in the UK, the US, Australia and western Europe have poorer quality data this year than last. The credit information company’s 2015 Global Data Quality Research among 1,239 organisations found a dramatic lack of data quality “ownership”, and 29% of respondents were still cleaning their data by hand.
 
The number of organisations that suspect inaccurate data has jumped from 86% in 2014 to 92%. Also, respondents reckoned 26% of their data to be wrong, up from 22% in 2014 and 17% in 2013. Some 23% of respondents said this meant lost sales, up from 19% in 2013.
Boris Huard, managing director of Experian Data Quality, said: “Getting your data strategy right is vital if you want to be successful in this consumer-driven, digitalised age. It is encouraging that companies are increasingly switching on to the value of their data assets, with 95% of respondents stating that they feel driven to use their data to understand customer needs, find new customers or increase the value of each customer.”

Poor Data Quality is cost million pounds to the companies.About one-third of organisations use automated systems, such as monitoring and audit technology (34%), data profiling (32%) or matching and linkage technology (31%) to clean their data. A total of 29% still use manual checking to clean their data.

Huard added: “As our Dawn of the CDO research demonstrated, a new breed of chief data officers, chief digital officers and director of insights are emerging – new roles that have come about in response to the pressure and opportunity presented by big data.”

However, only 35% of respondents said they manage data quality by way of a single director and nearly 63% are missing a coherent, centralised approach to data quality. More than half said individual departments still go their own way with respect to data quality enforcement, and 12% described their data quality efforts as “ad hoc”.

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.

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.

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…
