How to disable a user on Linux? That's easy! And if you don't already know, a quick search will give you the answer:
usermod -L user
Or so you might think. However, usermod -L does actually not disable the user, it only invalidates the user's password. If we are looking at a server and a user who has configured an ssh key, this will do nothing to prevent the user from logging in.

Week 1, #Unix History
Exhibiting one of the cardinal virtues of System Administrators โ laziness โ we're reusing a video from my #programming class to give a whirlwind history tour: Bell Labs, Berkeley & the Unix Wars, USL v. BSDi, the birth of #NetBSD & #FreeBSD, the development of GNU & its adoption of #Linux, all leading to Unix on your fridge, car, and mobile phone.

Week 2, Storage Virtualization
In this video, we cover the concept of storage virtualization -- combining individual disks into larger storage pools and utilizing resources from such a pool. This includes a discussion of RAID and some of the different supported levels as well as Logical Volume Management (by example on #Debian #Linux). We also illustrate some of these properties by example of ZFS (on #OmniOS).

Week 2, Partitions
In this video, we'll talk about how to divide a single disk -- physical or virtual -- and how the partitions relate to the physical structure of the disk. We show examples partitioning disks on #NetBSD, #OmniOS, and #Linux using the disklabel, fdisk, and format tools.

Week 3, Resizing file systems
Closing out our week of discussing the Dark Arts[1] of file systems, we show how to resize an existing file system on #NetBSD using the resize_ffs(8) tool. We first increase the size of a 512MB partition to 1GB, then shrink it down to 256MB:
For comparison, we then repeat the same exercise on #Debian #Linux, using resize2fs(8):

xkcd 2531: Cueball tells whitehat: "Long ago, in another age, I mastered these dark arts. But now I endeavor to live my ilfe such that I never need them. Their power leads only to ruin."

Week 6, Networking II: A simple request
In this video, we trace a simple HTTP request made via telnet to find out just how exactly our application knows how to connect to the remote server. In the process we learn about the ktrace(1) utility (strace(1) on #Linux), as well as the nsswitch.conf(5), hosts(5), and resolve.conf(5) configuration files.

Interest in LibreOffice, the open-source alternative to Microsoft Office, is on the rise, with weekly downloads of its software package close to 1 million a week as users look to avoid subscription costs. Thatโs the highest download number since 2023. It works on Linux, macOS, Windows and Unix like systems. https://www.computerworld.com/article/3840480/libreoffice-downloads-on-the-rise-as-users-look-to-avoid-subscription-costs.html
