Everyone has some persnal and confidential information which he he/she does not want to share with other people. In our computer there are some very confidential files also. To hide these files we generally use some third party softwares. But in this article, I will tell you a trick that will help you lock and hide any folder without installing any third-party software. With just a simple .bat file, you can protect your folders easily. Whenever you want to open the protected folder, a password will be required before the folder becomes visible and accessible. So, without further delay, follow the steps given below to password protect a folder : First of all, open the folder you want to secure with a password. You can see in the below animation that I’ve created a folder named “ Test, ” which consists of an image and an HTML file. Now, create a new text file inside the same folder. You can name the text file according to your choice. I’m naming it “lockFolder.txt.” Copy the followin

Visual Studio Code is a source-code editor made by Microsoft for Windows, Linux and macOS. Features include support for debugging, syntax highlighting, intelligent code completion, snippets, code refactoring, and embedded Git. In this post, we will see how you can install vs code on an android device. We will use one of the most popular android terminals simulation called termux. This will allow you to use all of VS code functionality using your Web Browser. Here are the steps how you can install : Step 1 - Install termux In order to install VS code, you will have to install termux using the following link. Download Termux The official release available on the play store doesn't seem to get the packages updated for some reason. If upgrade command doesn't work on your termux, try to change the default repo by using the command below: termux-change-repo Step 2 - Install ubuntu using termux Enter the following command on termux and ubuntu will start to install on your A

What is Django? Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. Built by experienced developers, it takes care of much of the hassle of web development, so you can focus on writing your app without needing to reinvent the wheel. It’s free and open source. It is used for rapid development of web based application. Advantages : 1. Django was designed to help developers take applications from concept to completion as quickly as possible. 2. Django takes security seriously and helps developers avoid many common security mistakes. 3. Some of the busiest sites on the web leverage Django’s ability to quickly and flexibly scale. Installing Django + Setup pip install django Creating a project The below command creates a new project django-admin startproject projectName Starting a server The below command starts the development server. python manage.py runserver Django MVT Django follows MVT(Model, View, Template) architectur

What is Flask Flask is a micro web framework written in Python. It is classified as a microframework because it does not require particular tools or libraries. It has no database abstraction layer, form validation, or any other components where pre-existing third-party libraries provide common functions. Importing Flask from flask import Flask Most used import functions These are some of the most used import functions from flask import Flask, render_template, redirect, url_for, request Boilerplate This is the basic template or barebone structure of Flask. from flask import Flask app = Flask(__name__) @app.route("/") def hello_world(): return "<p>Hello, World!</p>" app.run() route(endpoint) This is to make different endpoints in our flask app. @app.route("/") Route method Allowing get and post requests on an endpoint. methods = ['GET', 'POST'] Re-run while coding This is used to automatically rerun the pr

What is php? PHP is a general-purpose scripting language geared towards web development. It was originally created by Danish-Canadian programmer Rasmus Lerdorf in 1994. The PHP reference implementation is now produced by The PHP Group. PHP originally stood for Personal Home Page, but it now stands for the recursive initialism PHP: Hypertext Preprocessor. PHP code is usually processed on a web server by a PHP interpreter implemented as a module, a daemon or as a Common Gateway Interface (CGI) executable. On a web server, the result of the interpreted and executed PHP code – which may be any type of data, such as generated HTML or binary image data – would form the whole or part of an HTTP response. Various web template systems, web content management systems, and web frameworks exist which can be employed to orchestrate or facilitate the generation of that response. Additionally, PHP can be used for many programming tasks outside the web context, such as standalone graphical applicati

Database It is defined as a collection of interrelated data stored together to serve multiple applications. What is MySQL? MySQL is an open-source relational database management system (RDBMS). Its name is a combination of "My", the name of co-founder Michael Widenius's daughter, and "SQL", the abbreviation for Structured Query Language. A relational database organizes data into one or more data tables in which data types may be related to each other; these relations help structure the data. SQL is a language programmers use to create, modify and extract data from the relational database, as well as control user access to the database. In addition to relational databases and SQL, an RDBMS like MySQL works with an operating system to implement a relational database in a computer's storage system, manages users, allows for network access and facilitates testing database integrity and creation of backups. MySQL is free and open-source software under the ter

What is C++ Programming Language? C++ is a general-purpose programming language created by Bjarne Stroustrup as an extension of the C programming language , or "C with Classes". The language has expanded significantly over time, and modern C++ now has object-oriented, generic, and functional features in addition to facilities for low-level memory manipulation. It is almost always implemented as a compiled language, and many vendors provide C++ compilers, including the Free Software Foundation, LLVM, Microsoft, Intel, Oracle, and IBM, so it is available on many platforms. Basics Basic syntax and functions from the C++ programming language. Boilerplate #include <iostream> using namespace std; int main() { cout << "Welcome to C++"; return 0; } cout << It prints output on the screen cout << "This is C++ Programming"; cin >> It takes input from the user cin >> variable_name Data types Th

  What is JAVA? Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers write once, run anywhere (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but has fewer low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as reflection and runtime code modification) that are typically not available in traditional compiled languages. As of 2019, Java was one of the most popular programming languages in use according to GitHub, particularly for client–server web applications, with a reported 9 million developers. Basics Basic syntax a
