  • Bash Keyboard Shortcuts for the pro! - TREND OCEANS

    Typically, we use arrow keys to control shell behaviors like moving the cursor from one point to another point. Also, it’s quite common to make mistakes while writing commands and to correct these you may use arrow keys + backspace, which is not optimal at all.

    In the bash terminal, you can use several keystrokes to control the shell features that you are going to see.

  • How to Write and Run a C Program on Ubuntu – OSNote

    C language is one of the earliest programming languages. It is simple and easy to learn. Formerly C programming was performed on Turbo C, a discontinued integrated development environment. But nowadays it can be easily executed on different operating systems.

    In this guide, you will learn how to write your first C program using the Linux operating system which requires a GNU C compiler instead of an integrated environment. The following steps will show to install a GNU C compiler on Linux, how to write the source code, compile and execute the C program.

  • How to use Spring Boot with MongoDB | FOSS Linux

    Spring Boot is a Java-based open-source framework for creating microservices, which allows developers to deploy and develop services independently. Each service running has its process, thereby achieving the lightweight model that supports business applications. Microservices have several advantages: simple scalability, minimum configuration, lesser production time, container compatibility, and easy development.

    Spring boot provides a good platform for developers to build stand-alone and production-ready spring applications that you can just run; thus, one can get started with minimum configurations without needing an entire spring configuration setup.

    For instance, handling dependency management is complex for big projects; Spring Boot thus resolves this difficulty by providing a set of dependencies for the developer’s convenience. The Spring Boot application scans all the beans and package declarations when the application initializes; Besides, the Spring Boot application annotation includes component scan, Auto-Configuration, and Spring Boot Configuration.

  • How to use LXD Containers on Ubuntu 20.04 – VITUX

    Linux container virtualization (LXD) is similar to Virtual machines (e.g. KVM) but with more speed, efficiency and much lighter compared to virtual machines. LXD containers for OS like Ubuntu, Centos, Arch Linux, etc are easy to create. LXD uses the same Linux kernel which reduces the overhead of the addition of such kernels.

    In this article, we will show the installation and configuration process of LXD on Ubuntu 20.04 server. Also, we will explain how to start an LXD container and how to run commands inside the container.

  • How to install XFCE Desktop on Debian 11 | FOSS Linux

    Debian 11 provides so many options for choosing a desktop environment. One of the many great desktop options is Xfce which is light, simple, fast, and a very resource-friendly DE that works very well in almost any system.

    Whether you have already installed the default GNOME desktop that comes with Debian and would like to experience Xfce while keeping the GNOME DE or install Debian 11 along with Xfce, we will show you both the methods in this article today.

    There are so many use cases for installing Xfce DE on Debian 11. You can do a fair bit of customization to your liking and run so many utilities. The desktop is intuitive and highly resource-friendly. You can run it quite well on old hardware, and due to that reason, you can utilize any old PC lying around and set it up and running with the help of this desktop.

  • How to install Wireshark on Debian 11 Buster | FOSS Linux

    Wireshark is a free and well-known network communication link analyzer formerly known as Ethereal. It presents captured packet data in as much detail as possible. You can contemplate a network packet analyzer as a measuring gadget for cross-examining what is happening inside a network cable, just like an electrician utilizes a voltmeter to check what is inside an electric cable.

    Sometime back, Wireshark and look-alike tools were either expensive, proprietary, or both. Nevertheless, the dawn of Wireshark has enormously changed to the point that it is now available for free, open-source, and it has proven to be one of the best packet analyzers available in the market today.

  • How to Store Docker Container Data In Docker Volumes

    One option for automating a container with data is to store the data within the container image. However, this requires a copy of the data to be in each container you run, which can lead to wasted resources if the containers are scaled up. A better option is to store one copy of the data in a Docker volume and then share that volume between containers.

    You can think of a Docker volume as a folder that exists outside of the container filesystem but is still accessible by the containers running on the same host. When you create a new container, you can either mount an existing volume or create a new one. If you create a new volume, Docker will automatically create a new storage layer on the underlying host filesystem and initialize it with the data you specify.

    Once you have created a volume, you can use it to store any type of data, including static files, application data, or logs. You can also use volumes to share data between containers.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • 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.
