  • A Simple Way To Open A Port In Ubuntu 21.10

    Ubuntu, which is based on Debian’s design, provides multiple utilities, one of which allows it to open closed ports. Ports allow communication between devices. To perform their tasks, internet-facing services and applications generally listen for ports to connect from the outside. Communication between hosts via the internet is impossible without ports. Some ports are closed by default, and some are closed using a firewall. This article is about opening the ports on Ubuntu systems.

    A virtual point where a network connection begins, and stops is referred to as a port. The operating systems of computers manage ports, which are software-based. Each port is linked to a particular operation or service. Both TCP and UDP networks consist of ports. Some of the common ports are HTTP, FTP, SSSH, and so on.

  • How to Use Postgres Array Literal

    PostgreSQL database provides a facility to use arrays in the tables to store the same type of data in the bulk form. Arrays are the type of data that are used to store values of the same data type. PostgreSQL allows the column to store data by using multidimensional arrays. We have implemented all the examples in the PostgreSQL pgAdmin dashboard. In this tutorial, we have used many functions on the array in the tables of PostgreSQL. These functions include Data insertion in an array. The conversion of an array into the list is also explained.

  • Latex Horizontal Line

    Whenever it concerns composing and structuring a document, LaTeX has a lot of options. It’s extremely beneficial when working with numbers, but it has a lot of other uses as well. The greater complexity comes at a cost when compared to other word processors and typography applications. Yet if you want your text to appear the finest it can, LaTeX is very good enough to justify it. We can accomplish remarkably almost everything you need using LaTeX as far as you’re serious about learning a bit whenever you have to do anything such as create a straight edge.

    Let’s get started with the opening of the terminal shell in Ubuntu first with the shortcut key “Chtrl+Alt+T”.

  • Square Brackets Latex

    Brackets are signs, some of which are usually accustomed group statements or explain the sequence in which actions are to be performed inside an algebraic equation, like as: (simple braces), {curly brackets}, [square brackets], so on and so forth.

    In mathematical formulae, parentheses and braces are particularly prevalent. This article discusses how to alter the style and size of square parentheses in LATEX. Let’s get started now with opening your command shell of the Ubuntu 20.04 Linux system. Use “Ctrl+Alt+T” to do so. After that, you need to open the Latex texmaker for editing and creating the documents. This can be achieved by the terminal shell “texmaker” command on the shell.

  • Postgres where in array

    If you are familiar with object-oriented languages, you may have heard a very well-known concept of Arrays. Arrays are the data structures holding the same type of items or elements together on transmissible memory locations. To get the values from a specific memory location of an array, we must use some conditions in our code. The PostgreSQL database also allows keeping arrays as data in its tables. Getting values from the Arrays in PostgreSQL provides us with the “WHERE” clause to query data. If you are looking for a guide to learn about how to query data from arrays using the WHERE clause, then this guide is meant for you.

  • PostgreSQL Fuzzy Search

    A fuzzy word leads to partial or unclear. This search deals with the result that does not see the accurate or perfect search. The fuzzy search of data in PostgreSQL contains different approaches. Either through extensions or algorithms. But the phenomenon is applied in both ways. This article will contain all possible methods to demonstrate the working and implementation of fuzzy search in PostgreSQL data.

  • Postgres Security Definer

    Within this advanced and automated era of computers and technology, everybody wants to be secured along with their personal information. Same like that, databases are used to store information regarding a lot of things including personal information about people. Due to a lot of information, we also need to take care of our database security to not let anyone make use of it wrongly. Within the PostgreSQL database, we have to use many built-in databases to fetch some records from the tables and database. Just like many of these functions, one is the Security Definer function. As the title suggests that it must be something related to defining the security of the PostgreSQL database. As this concept is unique, complex, and new to most of the PostgreSQL users, we have decided to cover it within a whole new article. So, let’s have a little knowledge about the security definer property of methods now.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
