  • How to change the color of active windows in Plasma

    Alternatively, the title of this article is: how to change the color of active titlebars in Plasma. So what is this all about? In the Plasma desktop, the default theme is called Breeze. Until about Plasma 5.18, Breeze shipped with a light application theme, plus dark window borders. Excellent ergonomic choice, easy separation between foreground and background windows. None of the flat, modern nonsense.

    Recently, Plasma offers distinct all-light or all-dark themes, plus a mixed theme called Twilight, which gives you the old light-dark combo. Except ... it no longer works correctly. The window borders for active windows are light-themed. This is an under-reported, not-well-understood issue. I even had people emailing me telling me how to change the colors. Which I did, and the change does nothing, as there seems to be an unresolved bug in Plasma. I've been talking about this for more than a year. It's time for a dedicated article.

  • How to Mount Bitlocker Encrypted Windows Partition on Linux [Ed: A bit misleading as Bitlocker is not proper encryption; it's back doored in the sense Microsoft steals the keys [1, 2]]

    Here’s the scenario. My system came with Windows 10 Pro and that came with BitLocker encryption. I installed Ubuntu in the dual boot mode even with the BitLocker encryption enabled for Windows.

    You can easily access the Windows files from within Linux. No hi-fi stuff here. Just go to the file manager and click on the Windows partition which is located usually under the “Other Locations” tab.

  • What sysadmins need to know about Linux permissions | Enable Sysadmin

    Standard permissions in Linux are simple and direct, and they can be used to manage files and file shares on many different filesystems and file-sharing protocols. An access control list (ACL) adds even more functionality to Linux permissions. This article covers just a few permissions basics and provides links to other great Enable Sysadmin content that delves into permissions and ACLs in more detail.

  • Delete unused EBS (Elastic Block Storage) Volumes on AWS using a Lambda Function

    Amazon Elastic Block Store (EBS) is an easy-to-use, high-performance block storage service. It is like an external disk that can be attached to an EC2 Instance and used to store our data on it. If the EBS Volumes are not in use and not needed and still available in the account, then you will be charged by AWS for them unnecessarily. To save some cost, we will see the Lambda function which can be used to find and delete such unused EBS Volumes.

  • 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.
