Best Machine Learning Book for Beginners

You need a mixof different technologies for Data Science projects. Instead of learning many skills, just learn a few. The four main steps of any project are extracting the data, model development, artificial intelligence, and presentation. Attending interviews with many skills is not so easy. So keep the skills short.
A person with many skills can't perform all the work. You had better learn a few skills like Python, MATLAB, Tableau, and RDBMS. So that you can get a job quickly in the data-science project.
Out of Data Science skills, Machine learning is a new concept. Why because you can learn Python, like any other language. Tableau also the same. Here is the area that needs your 60% effort is Machine learning.  Machine Learning best book to start.

Interview Questions on Solidity

1. 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 an 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 (its state) that resides at a specific address on the Ethereum blockchain

4). Can the source code of smart contracts accessible to the outside world? 

A). No, it is not possible to access source code to the network. Also, there is 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 sandboxed and you cannot access it.


5). How many accounts are present in Ethereum?

A). There are two - One is external and the other one is a contract account.

6). What is Remix?

A). This is an online platform to develop smart contracts. Here, you can use solidity programs and develop your own smart contracts.
