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.

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

Shift+i—Typed text appears at the beginning of current line.

Shift+a—Typed text appears at the end…

The best Free mining tool that adds value to backup data

#data-mining-tool-that-adds-value-to-backup-data:
What is data mining?
The next big thing in backup will be a business use case to mine the data being stored for useful information. It’s a shame all that data is just sitting there wasted unless a restore is required. It should be leveraged for other, more important things. This method is called Data Mining Technique.
For example, can you tell me how many instances of any single file is being stored across your organization? Probably not, but if it’s being backed up to a single-instance repository, the repository stores a single copy of that file object, and the index in the repository has the links and metadata about where the file came from and how many redundant copies exist.
By simply providing a search function into the repository, you would instantly be able to find out how many duplicate copies exist for every file you are backing up, and where they are coming from.
Knowing this information would give you a good idea of where to go to delete stale or useless data. The complete knowledge on Data mining is a plus point to start further on this. After all, the best way to solve the data sprawl issue in the first place is to delete any data that is either duplicate or not otherwise needed or valuable. Knowing what data is a good candidate to delete has always been the problem.

Tools available
I think there may be an opportunity to leverage those backups for some useful information. When you combine disk-based backup with data deduplication, the result is a single instance of all the valuable data in the organization. I can’t think of a better, more complete data source for mining.
  • With the right tools, the backup management team could analyze all kinds of useful information for the benefit of the organization, and the business value would be compelling since the data is already there, and the storage has already been purchased. 
  • The recent move away from tape backup to disk-based deduplication solutions for backup makes all this possible.
Being able to visualize the data from the backups would provide some unique insights. As an example, using the free WinDirStat tool

A best use case is, I noticed I am backing up multiple copies of my archived Outlook file, which in my case is more than 14GB in size. If you have an organization of hundreds or thousands of people similar to me, that adds up fast.
The below are the best questions to use Data Mining tool
Are you absolutely sure you are not storing and backing up anyone’s MP3 files? How about system backups? Do any of your backups contain unneeded swap files? How about stale log dumps from the database administrator (DBA) community? What about any useless TempDB data from the Oracle guys? Are you spending money on other solutions to find this information? Are you purchasing expensive tools for email compliance or audits?
Advantages of Data mining
The backup data could become a useful source for data mining, compliance and data archiving or data backup, and can also bring efficiency into data storage and data movement across the entire organization.

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.

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…
