I've been a user of the Vim text editor for about two decades. For a little while, I have been customizing my Vim configuration, only using plugins for the last couple of years.

In a previous article, I covered Red Hat Ansible basics and installed Ansible, creating one control node named RHEL8 and four managed nodes (node1, node2, node3, and node4), all running Red Hat Enterprise Linux. Now, for Ansible to communicate with a managed node, you need to configure the control node and the managed nodes with a user account, and give that user account privilege escalation to run commands without having to enter a password.

Periodically, I need to come up with new passwords, some of which need to be more secure than others. My mind often seems to draw a blank when I have to create a new login, and this short Bash script fills that void.

Solid State Drives (SSDs) brought performance to the forefront of computing technologies, and their adoption is increasing not only in the data center but also in consumer-grade products. Unlike its traditional spinning hard disk drive (HDD) counterpart, SSDs comprise a collection of computer chips (non-volatile NAND memory) with no movable parts. Therefore SSDs are not kept busy seeking to new drive locations and, in turn, introducing latency. As great as this sounds, SSDs are still more expensive than HDDs. HDD prices have settled to around $0.03/GB; SSD prices vary but sit at around $0.13-$0.15/GB. At scale, that price gap makes a world of difference.

The Linux operating system is a true multi-user OS, meaning it assumes that there's data on every computer that should be protected, whether in the interest of privacy, security, or system integrity. Linux uses file ownership and permissions to manage file and folder access. For administrators who deal with different user environments all day, this system is easy to understand, calculate, and control.
