System Administration, Week 1: Warmup Exercise 1 - No Space Left On Device
In this video, we try to find out what happens when we run out of disk space as well as how the system behaves when use up all inodes. This is intended as a warmup exercise for our week 2 topic, introducing the concept of disk storage and filesystem behavior.
System Administration, Week 2: Storage Models and Disks
In this video, we'll introduce the larger topic of filesystems and storage. In particular, we'll discuss the conceptual storage models, such as Direct Attached Storage (DAS), Network Attached Storage (NAS), Storage Area Networks (SANs), and Cloud Storage.
System Administration, Week 1: AWS Aliases
System Administrators are notoriously lazy, and AWS commands a notoriously lengthy to type. In this video, we demonstrate the use of shell aliases and functions to save ourselves some typing whenever we run AWS EC2 commands.
The aliases and shell functions we use are available here:

System Administration, Week 1: Warming up to EC2
In this short video, we prepare for our first homework assignment and demonstrate how to launch a #NetBSD instance in AWS EC2.

System Administration, Week 1: UNIX History
We're borrowing this video from our "Advanced Programming in the UNIX Environment" class to give a brief summary of the history of the UNIX family of operating systems.

Dear #SysAdmin fedi – I am sure this has to exist, but I cannot find a tool like that.
I need a CLI tool that would canonicalize a DNS zone file. As in: put all the entries in a well-defined order, replace whitespace with a predefined pattern, organize the SOA section in a reproducible manner.
My basic need is being able to tell two zone files are 100% functionally equivalent, even if one uses tabs, the other spaces, and if entries are in completely random order, etc.
Anyone?

I have a #question about how #Mastodon works. If I #boost something (my own #toot or someone else's) in the morning, then come back in the afternoon and UNboost it, wait a while, then boost it again, does that toot show up in everyone's Home feeds again? Or do toots only get posted once, regardless, making unboosting-then-reboosting a waste of time? Does anyone know how the #DevsOfMastodon make this work? Any #MastoTips, #FediTips, or #boosts will be appreciated!
