Ethereum is known for its wide use in blockchain programming. Especially Solidity is used to write most of the blockchain applications known for today. Here, I’ll help you to learn solidity effortlessly.
Because you interact with the internet and the ethereum nodes at the same time, learning JavaScript becomes necessary to understand the data structures of solidity. Even more, ethereum nodes interact with nodeJS. Furthermore, solidity is written in JavaScript and it requires a basic understanding of JavaScript to work with the ethereum environment.
When I started learning solidity, my first course was face to face offered free because of my club’s connections. But I never stopped and decided to go further by purchasing a udemy course and looking for high-quality YouTube courses, you can level up your solidity skills by practicing. About offline courses, they can be really expensive for you to afford and online courses can allow you to look at the videos and ask questions lifetime.
Mentioned in my previous posts, taking notes by hand allows you not to forget easily when not practicing for a very long time. Even more, remembering the data structures can help you analyzing the codes even with the hugest projects imaginable. I managed to find most of the mistakes in my acceleration project in ethereum despite I was a beginner.
You don’t have to if you prefer using remix IDE for projects. But you might need to consider certain text editors for the best results in programming on ethereum. But, they require you to download certain packages before starting to write your code on these text editors to compile solidity code on your computer.

ML is type of AI
AI is a discipline , Machine Learning is tool set to achieve AI. DL is type of ML when data is unstructured like image, speech , video etc.
AI & ML was daunting and with high barrier to entry until cloud become more robust and natural AI platform. Entry barrier to AI & ML has fallen significantly due to

Bitcoin Cash was created as a result of a hard fork in the Bitcoin network. The Bitcoin Cash network supports a larger block size than Bitcoin (currently 32mb as opposed to Bitcoin’s 1mb).
Later on, Bitcoin Cash forked into Bitcoin SV due to differences in how to carry on its developments.
That’s Bitcoin Cash in a nutshell. If you want a more detailed review watch the complete video. Here’s what I’ll cover:
0:50 - Bitcoin forks
2:06 - Bitcoin’s block size debate
3:35 - Big blocks camp
4:26 - Small blocks camp
5:16 - Small blocks vs. big blocks arguments
7:05 - How decisions are made in the Bitcoin network
10:14 - Block size debate resolution
11:06 - Bitcoin cash intro
11:28 - BTC vs. BCH
12:13 - Bitcoin Cash (ABC) vs. Bitcoin SV
13:09 - Conclusion

Web applications are types of software applications that run on remote servers (source). Examples of web applications can range from word processors, to file scanners, video editing tools, shopping carts, and more. Web applications can be great additions to any website; they can even function as websites themselves (Facebook, Gmail, and Udacity’s classroom are all examples of popular web applications), so understanding how to set up and implement a web application is a fantastic skill to have.
For this guide, I am assuming that you already have a basic knowledge of npm
, node
and whatExpress Requests and Responses
are (or that you at least know what they are used for in their basic sense). Also, I assume that you know what the npm install
and mkdir
commands do. You have to know basic Typescript to implement — or at least know basic JavaScript to read and understand — the code below. Finally, this is the base for the backend of a web application. You still need to create a frontend application using a framework like Angular or an HTML/CSS file to make requests and display responses.
Before you start, it’s important that you create a folder in your favorite place on your computer. This can be anywhere as long as you have a sense of how you are going to find it later when you come up with an awesome project to start developing.

SQL is a standard language for storing, manipulating, and retrieving data in databases. In this article, I’ll teach you the very basic fundamentals of the SQL language and hope you will be able to write your own database queries at the end.
SQL stands for Structured Query Language and lets you access and manipulate databases.
Most of the actions you need to perform on a database are done with SQL statements. The following SQL statement selects all the records in the “Users” table:
SELECT * FROM Users;
The select statement is used to retrieve data from a database. The requested data is returned in a results table.
SELECT column1 FROM table_name;
The Select Distinct statement is used to return only distinct (different) values.
SELECT DISTINCT * FROM table_name;
Count
The following SQL statement lists the number of different customer countries:
SELECT COUNT(DISTINCT Country) FROM Customers;
The Where clause is used to filter records.
SELECT column1
FROM table_name
WHERE condition;
For example:
SELECT * FROM Users
WHERE Country='Netherlands';
The Where clause can be combined with AND, OR, and NOT operators. The AND and OR operators are used to filter records based on more than one condition:
The NOT operator displays a record if the condition(s) is NOT TRUE.
AND
SELECT column1, column2, ...
FROM table_name
WHERE condition1 AND condition2 AND condition3 ...;
OR
SELECT column1, column2, ...
FROM table_name
WHERE condition1 OR condition2 OR condition3 ...;
NOT
SELECT column1, column2, ...
FROM table_name
WHERE NOT condition;
