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).

Different Types Of Payment Cards awesome list people being used

The bank or plastic cards are many in the financial transactions people are using. This post tells you about all the payment cards being used in the financial world with some brief description. The below is the list of credit or payment cards of different types.
different credit cards

Top plastic cards being used in payments

  • The purpose o this card is to buy any item within the limit prescribed by banks to the cardholder. These cards can have both Magnetic stripe and Chip cards.
  • Nowadays all banks are issuing credit cards with CHIP and PIN. After entering the PIN by the cardholder, then transaction starts for further processing.

Types of Credit cards

  • Secure credit cards: Cardholder deposits a certain amount of money. When the cardholder goes unpaid, then the card issuer pay from it. Credit Union Cards: 
  • The private Credit Union owners issue credit cards. They usually charge less than what banks will charge Pre-paid cards: They technically equal to Debit cards. They pre-loaded with a certain amount, that amount, you can use your cards 

Debit (ATM, Cash) card

  • It is a relatively new method of payment. It is different from a credit card because the debit cardholder pays with the money available in their bank account, which is debited immediately in real time. 
  • A debit card seems to be more dangerous compared to a credit card because the debit card is directly linked to the bank checking account and usually allows ATM cash withdrawals. 
  • On the other hand, it is more protected by the required two-factor authentication (PIN number plus card itself). The real dangerous element of many branded debit cards is that they can be processed as credit cards, without entering the PIN.

Offline-Debit Cards

They do not require a PIN. Also, these cards differ from normal Debit Cards.

The Gift card. 

  1. It is similar to a debit card but usually does not have the protection provided by a PIN. The gift card is not linked to a bank account and normally "contains" fixed amounts of funds. 
  2. The card itself does not hold any financial information—the point-of-sale (POS) terminal communicates with the gift card provider during payment transactions in order to get authorization. 
  3. Gift cards are less dangerous than credit and debit cards because only fixed, often very limited, amounts of money can be stolen.

The fleet (or proprietary)

  • This card is similar to a credit card but can be used only at particular locations (usually gas stations and convenience stores) and for purchasing only limited types of merchandise (such as fuel and other automobile items). 
  • Fleet cards, even though often issued by major card brands, are less interesting to "bad guys" because they cannot be used for ATM withdrawal, online shopping, or purchases in department or grocery stores.

Co-brand cards

  • A co-branded card is a retail merchant credit card that is issued in partnership with a specific network processor. 
  • Co-branded cards are branded with the logo of the network processor and retailer. 

A private label credit card

It is a store-branded credit card that is intended for use at a specific store.
A private label credit card is a type of revolving credit plan managed by a bank or commercial finance company for either retail or wholesale manufacturers, such as department and specialty stores

Cash Cards

These are Debit cards, Payroll cards, Gift cards, and Pre-paid cards. The credit cards do not come under Cash Cards.

Closed Loop Cards

These cards have imprinted particular company logo. You can only utilize these cards only in that company. These cards do not contain Master or Visa cards logos

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.

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.

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.
