Launched: Red Shirt Jeff merch store

It makes me throw up a little in my mouth to say this, because it's such a YouTuber thing to do... but I now have an official merch store to go along with my YouTube channel:

Red Shirt Jeff store - launch products

The Red Shirt Jeff store has original designs that I find interesting or funny, and there are three shirt designs available at launch:

Hardware RAID on the Raspberry Pi CM4

A few months ago, I posted a video titled Enterprise SAS RAID on the Raspberry Pi... but I never actually showed a SAS drive in it. And soon after, I posted another video, The Fastest SATA RAID on a Raspberry Pi.

Well now I have actual enterprise SAS drives running on a hardware RAID controller on a Raspberry Pi, and it's faster than the 'fastest' SATA RAID array I set up in that other video.

A Broadcom engineer named Josh watched my earlier videos and realized the ancient LSI card I was testing would not likely work with the ARM processor in the Pi, so he was able to send two pieces of kit my way:

How I make my YouTube videos - 100K Office/Studio Tour

Early this year, I passed a major milestone on my YouTube channel—100,000 subscribers!

I've had a channel since 2006, but never really devoted time to it until last year, and I'm blown away by the positive response I've gotten publishing videos on Raspberry Pi, Kubernetes, Ansible and more.

To celebrate the milestone, I created a 'how it's made' video where I go behind the scenes and show how I made—from start to finish—my Argon One M.2 Raspberry Pi Case review video.

WiFi 6 is not faster than Ethernet on the Raspberry Pi

I didn't know it at the time, but my results testing the EDUP WiFi 6 card (which uses the Intel AX200 chipset) on the Raspberry Pi in December weren't accurate.

It doesn't get 1.34 gigabits of bandwidth with the Raspberry Pi Compute Module 4 like I stated in my December video, WiFi 6 on the Raspberry Pi CM4 makes it Fly!.

I'm very thorough in my benchmarking, and if there's ever a weird anomaly, I try everything I can to prove or disprove the result before sharing it with anyone.

In this case, since I was chomping at the bit to move on to testing a Rosewill 2.5 gigabit Ethernet card, I didn't spend as much time as I should have re-verifying my results.

Kubuntu Focus M2 Linux laptop review and MacBook Pro comparison

A few months ago, I replaced my Core i9 MacBook Pro with a Raspberry Pi 4 model B with 8GB of RAM for a day, and I made a video and a blog post about the experience.

Obviously there's a vast difference between a new Core i9 laptop with 32 GB of RAM, a dedicated GPU, and a 2 terabytes of fast storage and a tiny Raspberry Pi running ARM. So it wasn't a fair fight, but I could do a lot of things well enough, and every generation of Pi has gotten better.

Kubuntu Focus M2 Linux laptop

A few weeks ago, someone from Mindshare Management asked me if I'd like to do the same test, but this time with an almost one-for-one replacement laptop: the new Kubuntu Focus M2.

Review video: Check out the video that goes along with this review:

The Raspberry Pi 4 has a fan now - the Case Fan

Last year, I wrote a blog post titled The Raspberry Pi 4 needs a fan.

And in a video to go along with that post, I detailed the process of drilling out a hole in the top of the official Pi 4 case and installing a 5v fan inside.

But that solution wasn't great. The fan was a little loud and annoying, and would stay on constantly. And who wants to damage the nice-looking Pi Case by putting a hole right in the top?

The Raspberry Pi makes a great USB webcam for $100

There are many Raspberry Pi projects where I spend a few hours (or dozens of hours) building something with a Pi, and realize at the end that not only could I have purchased an off-the-shelf product to do the same thing for half the component cost, but it would work better too.

But this is not one of those projects:

Pi Webcam on Tripod - Pi Zero W and HQ Camera

The Raspberry Pi and its HQ camera make a surprisingly potent webcam, and if you want to cover the basics, and rival the image quality of all but the highest-end dedicated webcams, you can do it for under $100.

Above is a single frame from a recording I did with the HQ Camera on my Raspberry Pi Zero W connected as a standard USB webcam using the Camera app on Windows 10 on my Dell laptop.

Kubernetes 101 livestream series starts Nov 18th!

On November 18th, at 11 a.m., the first episode of my upcoming Kubernetes 101 livestream series will start on my YouTube channel.

The first episode will be available here on YouTube: Kubernetes 101 - Episode 1 - Hello, Kubernetes!.

You can find more details about the series on my Kubernetes 101 site, and there is also an open-source Kubernetes 101 GitHub repository which will contain all the code examples for the series.

In the spring, I presented a similar livestream series, Ansible 101, covering all the basics of Ansible and setting people up for success in infrastructure automation.
