This week I finally moved my gaming/Linux PC into my little office rack—it's that 2U box above the UPS at the bottom:

I remembered seeing Linus Tech Tips' 4U build in a video a couple years ago—but he has a full 42U rack in his basement. I don't have that much space—just 2U (technically 3U if I wanted) in my little under-desk studio rack.

So after working with them last year on a similar build (but with a prototype case), I got in touch with MyElectronics and they sent over their new production Mini ITX short-depth 2U PC case.

Radxa's Rock 5 model B is an ARM single board computer that's 3x faster than a Raspberry Pi. And that's just the 8-core CPU—with PCI Express Gen 3 x4 (the Pi has Gen 2 x1), storage is 7x faster! I got over 3 GB/sec with a KIOXIA XG6 NVMe SSD.

It's still half as slow as modern ARM desktops like Apple's M1 mini, or Microsoft's Dev Kit 2023 (see my review here). But it's way faster than a Pi, it comes with 2.5 Gig Ethernet, it has two M.2 slots on board... and, well—it also starts at $150!

...that was the question I asked my Dad, a radio engineer for many decades, who worked at the biggest AM station in St. Louis, KMOX. The station is approaching its centennial in 2025, as are—some YouTube commenters argue—its primary audience!

I recorded that video during my convalescence at my parents' house (I am feeling much better now, thank you!), and my Dad discussed a few reasons why AM radio—at least in the US—is not dead. But it is suffering.

In the video, I pointed out the current dichotomy:

This is the Compute Blade, and I'm test driving it in a four-node cluster:

For the past few years, my workflow for editing videos for my YouTube channel was the following:

1. Write and record narration / 'A-roll' using a teleprompter
2. Import recording into timeline, and chop out silent portions manually using the blade and/or range tools
3. Work on the rest of the edit (adding 'B-roll' and inserts).

Step 3 is where the vast majority of editing time is spent, especially when I need to add in charts, motion graphics, etc.

Raspberry Pi just announced their new Camera Module 3, which comes in four variations (standard and wide angle, normal and NoIR for infrared use), and costs $25 for the standard versions, and $35 for wide angle.

That's a step up from the older Camera Module 2, which cost $25 and only came in a 'standard' focal length.

I posted a video reviewing the Camera Module 3 on YouTube, and you can watch it here:

About 1 percent of Americans have diagnosed Inflammatory Bowel Disease (IBD) like Crohn's Disease or Ulcerative Colitis. And about 1 in 500 Americans (0.2%) have ostomies—small openings called stomas that help when their bowels get really screwed up (whether through disease, cancer, or trauma).

I'm in both groups. And this month, I had a second ostomy surgery. I now have a revised stoma, so now I'm in the 0.001% of Americans who have IBD and have had multiple ostomies!

I'm not sure that's the type of 'one-percent' I want to be...

But I digress.

As the son of a radio engineer, I've seen my share of radio towers. From small, rural AM and FM towers to urban 'constellation' towers serving dozens or even hundreds of services, there's a lot more than meets the eye.

My Dad and I visited the so-called 'FM Supertower' in St. Louis, MO twice now, to explore the tower and the supporting infrastructure below. Both of these visits are documented on our Geerling Engineering YouTube channel:

After battling IBD complications through the summer and fall, I've come to a point where surgery is necessary. You can learn more about my health issues in my lighthearted book about Crohn's Disease, You Only Have Crohn's Once!.

The surgery (an ostomy revision) will take place tomorrow, December 2, and it'll be a pretty rough recovery, so I'm not planning on doing any substantial work until at least 2023.

It's ironic I had just given a presentation titled Just Say No: Staying sane while you maintain weeks before learning the surgery was necessary. I was planning a video on the topic (burnout, protecting your time, and open source maintainership) this year, but I guess the blog post will have to do.

I have plenty of fun tech and software I want to highlight here and on YouTube (some of it detailed in my video embedded below), but for now it's all on the shelf waiting until my strength returns:

Last week Microsoft started selling their $599 Windows Dev Kit 2023, formerly known as 'Project Volterra'.

I got my hands on one after a little bit of a shipping delay, and promptly started tearing it down to see what's inside. You can click here to browse the entire Twitter thread where I posted pictures of the box contents and teardown, or view it below:
