System Administration
Week 11, Configuration Management I
In this video, we illustrate the general evolution of the management of system configuration and then talk about defining services by abstracting individual requirements for system-specific and service-specific aspects. We present a few sample snippets of Puppet, Chef, and CFEngine code to give you a taste of some common CM systems.

@ChrisLAS @ironicbadger really sad to hear about the #selfhosted #podcast reaching #EOL, I've been with you since the single-digit episodes, was an #SRE supporter then Jupiter.party, it was SelfHosted that brought me to #JupiterBroadcasting all those years ago.
Will be really sad to see it go, the cadence was great, and you two made wonderful hosts.
Sorry about the #AdWinter, afraid that is what is doing in so many JB shows like SH and Coder Radio.

Week 10, Backups by example
In this video, we illustrate how to perform backups using tar(1) (overcoming xkcd/1168), dump(8) and restore(8), and rsync(1), both locally and to a remote system.
OH on work slack while joking about how ridiculous infosec gatekeeping can be:
IF YOU’VE NEVER CHANGED YOUR BAUD RATE BY ADJUSTING DIP SWITCHES, I’M NOT INTERESTED IN YOUR CYBERSECURITY OPINIONS
On Friday which is typically a payday for weekly wages workers, there was some kind of outage that prevented #HomePay (from Care[dot]com) from paying out salaries to domestic workers like nannies, maids, babysitters, etc. They subsequently had a message on their website login screen, but for most of the day for many there was no clarity on when the funds would be dispersed to the workers. Customer care had long wait times due to this issue too. Since funds are typically collected on the Wednesday before, it was already gone from the families accounts who employed them. They eventually sent out communication indicating the delayed payroll would be paid out on Monday.
I’m surprised with such a major payroll platform having a payout outage and there was no news coverage I could find on the subject. I’m really interested in understanding what was the technical issues causing this problem. Also what banking service is HomePay using?
this week I'm reading Human Factors in Systems Engineering
there are so many gems I've highlighted already but really vibed with how the author clearly and simply expressed the impact of writing docs "early" here

a short lil blog post sharing how re-reading the evergreen etsy Debriefing Facilitation Guide helped me better investigate a mysterious sound....
Not sure if I asked this before: Does anyone use anything in particular to inject #apache logs into #SQL databases? I have been looking around and asking around and the only solid I got was "do not expect an apache module for that; it would introduce too much latency to each request" in #httpd@libera.chat.

Week 10, Backups: Core Concepts
In this video, we begin our discussion of backups by covering some core concepts and terminology, looking at full vs. incremental vs. differential backups and the difference between long-term storage and disaster recovery of files due to more localized data loss.
And here’s the big reveal:
Virtual flash cards for the key terms for all of DevOps Institute’s exams. I took the glossaries from all their public study guides, deduplicated them, converted the courses they appear in to tags and added an exam they missed.

Reposting because I forgot the number one rule of chronological timelines (don’t post when everyone’s asleep lol).

Week 9, Writing System Tools
This week we're going on a side-quest to discover solid #programming best practices that apply across simple scripting, prototyping, growing your tools, and owning a software product. We don't have videos for this topic, but the slides below include a lot of hopefully useful links ranging from coding style to ticket management and commit messages.
