  • Shading in Blender – Linux Hint

    Shading is an act of adding shade to a drawn object to give it a look and a perception of depth. Nobody likes white bland 3D objects. In 3D modeling, it is very significant to give objects some color material or texture. The process of adding shades to color materials and textures is called shading. Shading is so essential in 3D modeling that Blender has a dedicated workspace for shading.

    Shading workspace will automatically bring us in the “Look Dev” mode. Look Dev mode approximates lights and gives a general idea of the output of the object or scene. The shader editor will show the shader nodes of the selected object. Every object in Blender can be assigned a default material with white shading. And these shaders can be manipulated in the Shading workspace. You can add material to any object by going into the material tab.

  • Blender Viewport Navigation – Linux Hint

    The viewport is the main view of Blender that a user sees after getting it installed. At first look, it may appear intimidating, but it has become a lot comprehensible after the launch of the 2.80 version. The interface is less complicated and simple to learn.

    The viewport is a window that allows you to look around the scene or object you created. Viewport and camera view can be confusing, but both are not similar. A camera is an object in the scene, whereas the viewport is a part of the interface.

    Basics of navigating viewport include rotating, zooming, and panning the perspective of the view. There are various ways to navigate in the viewport.

  • Blender Cloud Rendering – Linux Hint

    How does it feel when you create a beautiful scene in Blender with high definition textures, shaders, particles, and volumetric effects and when you click on rendering, it just says that you need 2 hours to render just one frame? Yes, it feels discouraging. It is not easy to render a high-quality image or animation using an ordinary workstation.

    It is not a piece of cake to render in Blender, especially when working in Cycles (rendering engine). 3D rendering requires a lot of computing power. If you are rendering an animation, then it will take much more power and time. It would be best if you had a powerful PC with high-end specifications to get decent results. The trouble is the affordability of a robust workstation; they are costly. But this issue is fixable; just use cloud rendering.

  • Delete/Drop a Database in MySQL – Linux Hint

    MySQL is an RDBMS (Relational Database Management System) that is famous for its speed and easy-to-use interface.

So, feel free to read on if you have already installed MySQL on your system and have some dummy databases in MySQL that you want to delete.

  • CentOS 8 Restart Network – Linux Hint

    Among the most frequent system administration practices is the process of restarting the network. To connect your machine with the Internet, a sound networking service is always required. At times, due to undesirable issues, the networking service in a particular operating system may start malfunctioning. If the issue is temporary, then it can be resolved simply by restarting your networking service.

    There are multiple methods that you can use in any operating system to restart the system’s networking service. Today, we walk you through the two primary methods of restarting the network service in CentOS 8, one of the most popular distributions of the Linux operating system.

    If you are using a system based on CentOS 8 and are not able to establish a secure connection with your network, you would be shocked by how many issues a quick restart can solve. You can restart the Linux networking service using various commands, but you must execute the commands to restart the network using sudo or su commands as a root user.

  • WireShark in-depth Tutorial – Linux Hint

    Wireshark is an open-source and free network traffic inspection tool. It captures and displays packets in real-time for offline analysis in a human-readable format with microscopic details. It requires some sound knowledge of basic networking and is considered an essential tool for system administrators and network security experts.
    Wireshark is the de-facto go-to tool for several network problems that vary from network troubleshooting, security issue examination, inspecting network traffic of a suspicious application, debugging protocol implementations, along with network protocol learning purposes, etc.

    The Wireshark project was initiated in 1998. Thanks to the global networking expert’s voluntary contribution, it continues to make updates for new technologies and encryption standards. Hence, it’s by far one of the best packet analyzer tools and is utilized as a standard commercial tool by various government agencies, educational institutes, and non-profit organizations.

  • 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.
