Version Control with Git: A Beginner’s Guide If you are a developer, you probably know how important it is to keep track of your code changes and collaborate with other developers on a project. But how do you do that effectively and efficiently? The answer is version control. Version control is a system that records changes to a file or set of files over time so that you can recall specific versions later. It allows you to revert files back to a previous state, compare changes over time, see who last modified something, and more. Version control also enables you to work with other developers on the same code base without stepping on each other’s toes. One of the most popular version control systems in the world is Git. Git is a free and open source distributed version control system that is designed to handle everything from small to very large projects with speed and efficiency. Git has many features that make it superior to other version control systems, such as: Cheap local branchin...

 C++ bindings and thread pool are two different concepts in C++ programming. Let me explain them briefly. C++ bindings are a way of creating interfaces between C++ and other languages, such as Python, Java, or C. C++ bindings allow programmers to use C++ libraries or classes in other languages, or vice versa. C++ bindings can be implemented using various techniques, such as: Using the C interface of C++, which is compatible with most languages that support calling C functions. Using a foreign function interface (FFI) library, such as Boost.Python or SWIG , which can generate wrappers for C++ code automatically. Using a language-specific tool, such as pybind11 or JNI , which can expose C++ classes or functions to Python or Java respectively. A thread pool is a design pattern that creates and manages a set of threads that can execute tasks concurrently. A thread pool can improve the performance and scalability of an application by reducing the overhead of creating and destroying th...

Databases and SQL: A Beginner’s Guide If you are interested in learning how to store, manipulate, and retrieve data using a computer, then you need to know about databases and SQL. In this blog post, I will explain what databases and SQL are, why they are important, and how you can use them to create and query your own data. What is a database? A database is a collection of interrelated data that is organized in a structured way. A database can store various types of data, such as text, numbers, images, audio, video, etc. A database can also have different levels of complexity, from a simple spreadsheet to a large-scale system that handles millions of transactions per day. A database is managed by a software called a Database Management System (DBMS). A DBMS is responsible for creating, maintaining, and controlling the access to the database. Some of the commonly used DBMS are MySQL, SQL Server, Oracle, MongoDB, etc. What is SQL? SQL stands for Structured Query Language. It is a standa...

 Front-end vs. Back-end Development: What’s the Difference? If you are interested in web development, you might have heard the terms front-end and back-end development. But what do they mean, and what are the differences between them? In this blog post, I will explain the basics of front-end and back-end development, the skills and tools required for each, and the benefits and challenges of both. What is front-end development? Front-end development is the process of creating the user interface (UI) of a website or a web application. The UI is the part that users see and interact with, such as the layout, colors, fonts, images, buttons, menus, forms, etc. The goal of front-end development is to make the website or web application look good, responsive, and user-friendly. Front-end developers use a combination of three main languages: HTML, CSS, and JavaScript. HTML (Hypertext Markup Language) defines the structure and content of the web page. CSS (Cascading Style Sheets) controls th...

Bitwise Operators in C/C++ In C, the following 6 operators are bitwise operators (also known as bit operators as they work at the bit-level). They are used to perform bitwise operations in C. The & (bitwise AND) in C or C++ takes two numbers as operands and does AND on every bit of two numbers. The result of AND is 1 only if both bits are 1. The | (bitwise OR) in C or C++ takes two numbers as operands and does OR on every bit of two numbers. The result of OR is 1 if any of the two bits is 1. The ^ (bitwise XOR) in C or C++ takes two numbers as operands and does XOR on every bit of two numbers. The result of XOR is 1 if the two bits are different. The << (left shift) in C or C++ takes two numbers, the left shifts the bits of the first operand, and the second operand decides the number of places to shift. The >> (right shift) in C or C++ takes two numbers, right shifts the bits of the first operand, and the second operand decides the number of places to shift. The ~ (bit...
