Ansible Questions and Answers from the final Ansible 101 livestream

Over the past four months, I live-streamed a series of episodes covering all the basics of using Ansible for infrastructure automation in my Ansible 101 series on YouTube.

In the last episode of the series, I asked viewers to send in questions that I could answer on the final live stream, and there were many great questions sent in. Some of those questions and my answers are posted below, and you can also view the entire episode in the embedded video below:

How do you organize your Ansible tasks? What are the best practices for Ansible?

Raspberry Pi Cluster Episode 5 - Benchmarking the Turing Pi

At this point, I've showed you how you can use the Turing Pi as a Kubernetes cluster to run different things. I barely scratched the surface of what's possible with Kubernetes, but I'm planning on doing another series exploring Kubernetes itself later this year. Subscribe to my YouTube channel if you want to see it!

In this post, I'm going to talk about the Turing Pi's performance. I'll compare it to a more traditional Raspberry Pi cluster, my Pi Dramble, and talk about important considerations for your cluster, like what kind of storage you should use, or whether you should run a 32-bit or 64-bit Pi operating system.

As with all the other work I've done on this cluster, I've been documenting it all in my open source Turing Pi Cluster project on GitHub.

Ansible 101 live streaming series - a retrospective

Ansible 101 Retrospective

In late March, as the COVID-19 pandemic hit the US, I decided to make my Ansible books free to help people level-up their skills at home. That offer was generously extended by Device42 in April.

Something happened that I never expected, but in hindsight is pretty amazing: while the books were free, paid sales went up 400%!.

Anyways, in the midst of that, I also realized after getting my equipment in order for live streaming, I could teach a free 'Ansible 101' course on YouTube. So I asked people if they'd be interested, got a very enthusiastic 'YES', and tried to make a concise but somewhat entertaining live series on all things Ansible.

Recording multiple camera angles, full-size, simultaneously, on a Mac

I've been doing a lot of video production work for the past few months, both for my YouTube channel, and in helping people with their live streams, and one thing that I miss by not having dedicated (and expensive!) video production system like a NewTek TriCaster is being able to record multiple camera angles at their full resolution simultaneously on my Mac.

There are a lot of little conveniences you get used to if you do professional live video production with high-end equipment that you often can't replicate in a budget studio... like my desk here at my house.

Raspberry Pi Cluster Episode 4 - Minecraft, Pi-hole, Grafana and More!

This is the fourth video in a series discussing cluster computing with the Raspberry Pi, and I'm posting the video + transcript to my blog so you can follow along even if you don't enjoy sitting through a video :)

In the last episode, I showed you how to install Kubernetes on the Turing Pi cluster, running on seven Raspberry Pi Compute Modules.

In this episode, I'm going to show you some of the things you can do with the cluster.

The world's first Drupal 9 LIVE upgrade!

Update: The upgrade was a success! The site is now on Drupal 9.0.0, yay!

I'm planning on upgrading my www.pidramble.com website from Drupal 8 to Drupal 9 LIVE on my YouTube channel today, in honor of the #D9Launch today!

The site is currently running on a single Raspberry Pi on my desk in my basement... so this would not only be the world's first live Drupal 9 upgrade, it may possibly be the first-ever Drupal 9 site running on a Raspberry Pi!

Fingers crossed, I hope Drupal 9.0.0 will be ready to go by 5:00 p.m. US Eastern time (today, June 3rd)—if so, the stream will begin at that time, and I've embedded it below:

25K Open Source Pay-it-Forward Pi 4 8GB Giveaway!

This morning, my YouTube channel passed 25,000 subscribers, and that's only a couple weeks after I was amazed to see it pass ten thousand! I'm working on my next video on the Turing Pi cluster, and it will be out very soon, but I thought I'd try to do something special for 25,000 subscribers.

The videos I make for my YouTube channel wouldn't be possible without me relying on the work of thousands of people, working on thousands of open source projects. I want to see how much I can pay it forward for them in this video.

Raspberry Pi 4 goes 8GB, and Raspberry Pi OS goes 64-bit!

This morning the Raspberry Pi Foundation announced a new 8 GB version of the Raspberry Pi 4. They've been selling a 1, 2, and 4 GB version for the past year, and I've been using all three models in my projects.

More RAM is always better, because you can fit more applications on the same Pi, especially if you're using them in a Kubernetes cluster, like I am in my Turing Pi Cluster series!

The FINAL Drupal 7 to 8 migration live stream - May 19

May 19 Update: It was a total success, yay! This site is now running Drupal 8.

Drupal 7 to Drupal 8 live migration - FINAL EPISODE May 19 at 11 am ET

Over 100 days in, the big day has finally arrived—it's time to upgrade this website from Drupal 7 to Drupal 8! The entire process has been documented, one hour at a time, in my 'Drupal 7 to 8' live streams. Visit that link to view all the previous episodes, from setting up a new Drupal codebase, to running the first test drush migrate-upgrade command, to upgrading this site's theme from PHPtemplate in Drupal 7 to Twig in Drupal 8.

Some of the highlights:
