Ubuntu VI editor Commands to learn today

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.

Scrum Vs Agile Methodology best explained with more details


Life cycle of scrum with more details
#Life cycle of scrum with more details:
Scrum is part of the Agile movement. Agile is a response to the failure of the dominant software development project management paradigms (including waterfall) and borrows many principles from lean manufacturing. In 2001, 17 pioneers of similar methods met at the Snowbird Ski Resort in Utah and wrote the Agile Manifesto, a declaration of four values and twelve principles. 

These values and principles stand in stark contrast to the traditional Project Manager’s Body Of Knowledge (PMBOK). The Agile Manifesto placed a new emphasis on communication and collaboration, functioning software, team self organization, and the flexibility to adapt to emerging business realities.


How Does Scrum Fit With Agile?
The Agile Manifesto doesn’t provide concrete steps. Organizations usually seek more specific methods within the Agile movement. These include Crystal Clear, Extreme Programming, Feature Driven Development, Dynamic Systems Development Method (DSDM), Scrum, and others. While I like all the Agile approaches, for my own team Scrum was the one that enabled our initial breakthroughs. Scrum’s simple definitions gave our team the autonomy we needed to do our best work while helping our boss (who became our Product Owner) get the business results he wanted. Scrum opened our door to other useful Agile practices such as test-driven development (TDD). Since then we’ve helped businesses around the world use Scrum to become more agile. A truly agile enterprise would not have a “business side” and a “technical side.” It would have teams working directly on delivering business value. We get the best results when we involve the whole business in this, so those are the types of engagements I’m personally the most interested in.

What’s The Philosophy Behind Scrum?
Scrum’s early advocates were inspired by empirical inspect and adapt feedback loops to cope with complexity and risk. Scrum emphasizes decision making from real-world results rather than speculation. Time is divided into short work cadences, known as sprints, typically one week or two weeks long. The product is kept in a potentially shippable (properly integrated and tested) state at all times. At the end of each sprint, stakeholders and team members meet to see a demonstrated potentially shippable product increment and plan its next steps.


Scrum is a simple set of roles, responsibilities, and meetings that never change. By removing unnecessary unpredictability, we’re better able to cope with the necessary unpredictability of continuous discovery and learning.

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…
