The (almost) perfect mini NAS for my mini rack

The GMKtec G9 N150 4-bay NVMe mini PC is $240 and the nearly perfect NAS for my mini rack:

It has an Intel N150 4-core SoC with halfway-decent Intel UHD integrated graphics, 12 GB of LPDDR5 RAM, dual 2.5 Gbps Ethernet, WiFi 6, and the best part: 4 integrated M.2 NVMe slots.

Granted, splitting up the 9 PCIe Gen 3 lanes limits the performance a bit, but there are


It's easier than ever to de-censor videos

Last month I asked people to hack part of my YouTube video , specifically to de-pixelate the contents of a folder I had pixelated starting at the 4:57 mark.

For years, people have used the censor tool to blur or pixelate out parts of videos where there's sensitive information. And for years, every time I've used it, I get a few comments from people saying that's not a safe way to censor information.

So


Raspberry Pi cluster spotted inside $6k audio processor

People often ask me whether Pi clusters are useful besides just tinkering. I've built my fair share , including my most recent 'Lamp Rack' Kubernetes-in-a-Lamp cluster .

Well... I have a definitive answer: the Orban Optimod 5000-series audio processors:

These rackmount units each include a 3-node Raspberry Pi cluster, and they cost between $6,000-15,000! I found this specimen at the Orban booth at


BPS is a GPS alternative that nobody's heard of

I came to the NAB (National Association of Broadcasters) show this year with my Dad to learn more about time in broadcast and live production.

I was expecting to learn more about grandmaster clocks, AV sync, timing in protocols like Dante, Livewire, AES67, and more—and I have . But then on the first day here I found this odd little corner of the building with a completely empty booth:

BPS Demo Booth - it is empty

Running the LAMP Stack in a Lamp Rack

Lamp rack for a LAMP stack - Jeff Geerling mini rack

I typically don't do anything for April Fool's Day, but this year I thought I'd unite a bit of a meme in the homelab community with something I wanted to make a video on anyway: a lamp rack .

What's a lamp rack? Well, you're looking at one! It's a floor lamp with an integrated mini rack !

I didn't want to make a video about a floor lamp, but more on the fact you don't need fancy


DIY PTP Grandmaster Clock with a Raspberry Pi

tl;dr : I set up an open source Time Pi project to build a stratum 1 PTP and NTP timeserver using a Raspberry Pi.

Time is important to modern society, and most of us have a clock on our wrist that's more accurate than at any time in human history. But highly precise time is important in many industries, especially robotics, finance, and media production. And with tech like VR working its way into homes, precise time may become more important there , too.

The timing industry

Never in a million years...

...would I have imagined my video on whether a pigeon is faster than the Internet would end up on a popular Italian quiz show, L'Eredita. Specifically, in the March 26th episode (playable in Italy, or with an account).

L'Eredita quiz show question on courier pigeons

The question, roughly translated:

A test by the expert Jeff Geerling from 2023 proved that in transporting data the carrier pigeons can be more, what?

  • More reliable than a registered letter
  • Faster than DSL.
  • More precise than a human courier

I won't connect my dishwasher to your stupid cloud

This weekend I had to buy a new dishwasher because our old GE died.

I bought a Bosch 500 series because that's what Consumer Reports recommended, and more importantly, I could find one in stock.

After my dad and I got it installed, I went to run a rinse cycle, only to find that that , along with features like delayed start and eco mode, require an app.


Exploring WiFi 7 (at 2 Gbps) on a Raspberry Pi 5

Raspberry Pi 5 with Waveshare WiFi HAT+

Last time I seriously dug into 6 GHz WiFi was with 6E on a Raspberry Pi CM4 with Intel's AX210 card , in 2023.

Back then—and even up until recently—using WiFi 6E or WiFi 7 on a Raspberry Pi meant recompiling Linux , as the iwlwifi Linux drivers weren't included with the default Pi OS install.

But recently, the Intel WiFi drivers were added by default , and now all that's required is loading


YouTube scares me; I need RAID 1 for my video content

Jeff Geerling - YouTube Channel Home

I've published 500 videos in 18 years on my YouTube channel .

It was different back in 2006, when I moved from Google Videos over to YouTube. Monetization wasn't a thing, and we all just posted video online for the fun of it.

Fast forward to today, and it seems like AI slop is set to take over the entire platform, proving the Dead Internet Theory right. You have AI videos with AI bots watching and commenting, and YouTube enables it by
