System Administration: Week 11: Configuration Management, Part I

In this video, we're starting our discussion of Configuration Management. We illustrate the general evolution of the management of system configuration and talk about defining services by abstracting individual requirements for system-specific and service-specific aspects. We present a few snippets of Puppet, Chef, and CFEngine code to give you a taste of some common CM systems.

Hi. I'm Saket from the Netherlands.

He/him.

I believe #kindness is key to our survival.

Fascists, racists, TERFs, misogynists, etc., give me a wide berth (ideally so wide you fall off the edge of your platform into open-mindedness)

I'm interested in conversations with thoughtful conversationalists on topics such as: #books, #writing, #climate, #politics, #philosophy, #banter, #scripting, #apps, #fediverse, #softwaredesign, #martialarts, #ttrpg, #videogames, #design, #devops

System Administration: Week 10: Time Machines and Snapshots

Get in, we have to go back... to the snaphots!

In this video, we demonstrate another form of backup and redundancy via filesystem snapshots using fss(4) on NetBSD, ZFS on OmniOS, and how NetApp's WAFL and macOS's Time Machine work.
