Raspberry Pi Cluster Episode 6 - Turing Pi Review
A few months ago, in the 'before times', I noticed this post on Hacker News mentioning the Turing Pi , a 'Plug & Play Raspberry Pi Cluster' that sits on your desk.
It caught my attention because I've been running my own old-fashioned 'Raspberry Pi Dramble' cluster since 2015.

So today, I'm wrapping up my Raspberry Pi Cluster series with my thoughts about the Turing Pi that I used to build a 7-node Kubernetes cluster.

Earlier this year, I started recording more videos and doing live streams in my office. Originally I just used a webcam, a Logitech C920 .
The Pi 4 Compute Module might support NVMe storage
There is a companion video to this post: Is fast NVMe storage coming to the Raspberry Pi? .
A couple days ago, Tom's Hardware posted an article stating NVMe support might be coming to the Raspberry Pi Compute Module 4 .
On the first episode of The Pi Cast , Eben Upton, the CEO of Raspberry Pi, said "microSD will always be the baseline for storage", but "it's fairly likely we'll support NVMe soon on the Compute Module 4, to some degree, using

Transition from blogging to YouTube - my experience
Reading a Hacker News post linked to a YouTube video yesterday, I spotted this comment by user tomerico:
I think [ Shane Wighton's Stuff Made Here YouTube channel ] illustrates well the transition from personal blogs to youtube videos.
If you go to his projects blog, https://shane.engineer/ you could see very detailed blog posts in the past that go deeply into the engineering, including code snippets. However, he only really go traction when starting to publish youtube videos, specifically youtube video with a

Drupal VM 6 'Rectifier' is here!
I just released Drupal VM 6.0.0 today, and it is the best version of Drupal VM yet!
The main goals for this new version are stability and compatibility .
Originally I was going to drop some features that are helpful for people running older Drupal 7 sites, but since Drupal 7's End of Life was just extended into 2022 , I decided to extend the support for some features like Drush make files, as many users of Drupal VM still maintain Drupal 7 sites, or use
UASP makes Raspberry Pi 4 disk IO 50% faster
You can view a video related to this blog post here: Does UASP make the Raspberry Pi faster? .
A couple weeks ago, I did some testing with my Raspberry Pi 4 and external USB SSD drives. I found a USB 3.0 SSD was ten times faster than the fastest microSD card I tested.
In the comments on the video associated with that post, Brad Manske mentioned something I never even thought about. He noticed that I had linked to an Inateck USB 3.0 SATA case that didn'

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:
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

Ansible 101 live streaming series - a 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
What does Apple Silicon mean for the Raspberry Pi and ARM64?
Note: There's a video version of this blog post available here: What does Apple Silicon mean for the Raspberry Pi and ARM64?
A couple weeks ago I tried using the latest Raspberry Pi 4 8 gig model as my main computer for a day, and I posted a video about my experience .
Besides many diehard Linux fans complaining in the comments about my apparent idiocy caused by being a Mac user, the experience taught me one thing: A lot of software still isn't built for 64
