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.

Top SAP HANA Iot must read Interview Questions(2 of 3)

1. How parallel processing is achieved in SAP HANA?
The phrase "divide and conquer" (derived from the Latin saying divide et impera) typically is used when a large problem is divided into a number of smaller, easier-to-solve problems. Regarding performance, processing huge amounts of data is a problem that can be solved by splitting the data into smaller chunks of data, which can be processed in parallel.

2.How data portioning will happen in SAP HANA?
Although servers that are available today can hold terabytes of data in memory and provide up to eight processors per server with up to 10 cores per processor, the amount of data that is stored in an in-memory database or the computing power that is needed to process such quantities of data might exceed the capacity of a single server. To accommodate the memory and computing power requirements that go beyond the limits of a single server, data can be divided into subsets and placed across a cluster of servers, which forms a distributed database.

The individual database tables can be placed on different servers within the cluster. Tables bigger than what a single server can hold can be split into several partitions horizontally (a group of rows per partition) or vertically (a group of columns per partition), with each partition on a separate server within the cluster.

3. What are key features in SAP HANA?
SAP HANA database- The SAP HANA database (which is also referred to as the SAP in-memory database) is a hybrid in-memory database that combines row-based, column-based, and object-based database technology that is optimized to use the parallel processing capabilities of current hardware. It is the heart of SAP offerings, such as SAP HANA.

SAP HANA appliance (SAP HANA) -SAP HANA is a flexible, data source-neutral appliance with which you can analyze large volumes of data in real time without needing to materialize aggregations. It is a combination of hardware and software and is delivered as an optimized appliance with SAP's hardware partners for SAP HANA.

4. Basics of SAP HANA internet of things?

5) What is SAP HANA internet of things?
The customers of discrete manufacturing companies are more and more demanding. They expect individualized solutions with a combination of products and services. To understand their customers’ unique requirements, companies have to capture and analyze real-time data from products through embedded software. Manufacturers are responding with cloud-based platforms. With output and throughput relevant across the entire product and customer life cycles, manufacturers can serve customers in new and more cost-efficient ways, expanding their business opportunities.

6) Case Studies of SAP HANA internet of things?

Many SAP customers are transforming business models with IoT. Let me give you three examples. Using the SAP HANA Cloud Platform and supply chain management solutions including production planning and shop floor management, Harley Davidson increased output by 25 percent by creating an end-to-end connected manufacturing operation from customers to shop floor. Delighted customers can now configure a customized motorcycle up to six hours before final production versus the previous time of 21 days.(ref:SAP)

Another example is how Kaeser transformed its business model. Instead of compressors, Kaeser now sells cubic meters of compressed air through their “Sigma Air Utility” service. Sensors on its compressors at customer sites capture and transmit real-time air metering and quality data for faster error resolution, minimizing downtime. Kaeser is working with SAP on a predictive maintenance solution for its equipment.(ref:SAP)

A third example is GEA, one of the world’s largest suppliers for the food processing industry. GEA is using SAP Predictive Maintenance & Service and SAP IoT connector on the HANA Cloud Platform to help remote technicians monitor machine performance in real-time, identifying and solving problems faster while reducing downtime and increasing product quality.(ref:SAP)

7) What is the motto for IOT?
When processing power is so cheap, you can afford to put processors in places that you couldn't before—not just a business workstation or a home PC but also a telephone, an electricity meter, a bedside lamp, or a teddy bear. We can make objects intelligent. We can make them think and speak. Pundits have dubbed this "physical computing", "ubiquitous computing" or "ubicomp", or "the Internet of Things". Whatever you choose to call it.

8) What is basic architecture in IOT?

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.

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…
