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

Early in 2020, I kicked off the Ansible 101 live streaming series. I wrote an Ansible 101 retrospective post and decided to give it another go, this time covering Kubernetes .

Starting late in 2020 and wrapping things up today, I streamed a new 10-episode series, Kubernetes 101 (the first episode is embedded below).

I'm a fan of Raspberry Pi cases that keep my Pi cool. And the cases made by Argon Forty have great cooling, which is one reason they're a popular choice. Their latest Argon One M.2 case also adds a built-in high speed SSD drive slot!

A few months ago, someone from Argon Forty reached out and asked if I'd like to review the Argon ONE M.2 , after they watched my video on booting a Pi 4 from an external SSD, and

I've worked in open source my entire career ¹ . To say that I'm worried about the impact recent events have on the open source ecosystem would be an understatement.

In the past couple months:

• Red Hat effectively killed CentOS
• Elastic effectively killed Elasticsearch

People may rightfully refute these statements, but the statements are more complicated than you might think. Killing a project doesn't mean the project will vanish overnight, but what has happened so far is two very large companies in the 'enterprise open source' space

tl;dr : The Raspberry Pi Pico is a new $4 microcontroller board with a custom new dual-core 133 MHz ARM Cortex-M0+ microprocessor, 2MB of built-in flash memory, 26 GPIO pins, an assortment of SPI, I2C, UART, ADC, PWM, and PIO channels.

It also has a few other party tricks, like edge castellations that make it easier to solder the Pico to other boards.

The Pico is powered by a new RP2

I recently received an email from someone asking me how I got the voice recording in my videos to sound so clear and strong. The answer to that question is much more complex than I'll deal with here, but that person asked me mostly about the microphone I used, and if that could make a big difference in getting better recordings. Here's what I replied:

I currently use an EV RE320 in a shock mount .

I have it plugged into a Behringer U-Phoria audio interface

This is a quick blog post, mostly for my own reference.

I finally got sick of a certain government website thinking that preventing pasting passwords into certain forms was some sort of security feature, so I am documenting my workaround in Safari for stupid forms written by compliance-minded folks (the same who think that expiring passwords every 30 days leads to any kind of better security).

In Safari, select Develop > Show Javascript Console (or press ⌥⌘C, that's Option +

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 got this Rosewill RC-20001 PCIe 2.5 Gbps Network Adapter working on the Raspberry Pi Compute Module 4.

Right after I got the card working, though, I tested it in an external powered PCI Express riser, and that test released the card's magic smoke. Oops.

Here's a dramatic re-enactment that's actually pretty accurate to what it looked like in real life:
