For LTX 2023, I built this:

This build centers around the Time Card mini. Typically you'd install this PCI Express card inside another computer, but in my case, I just wanted to power the board in a semi-portable way, and so I plugged it into a CM4 IO Board.

The Time Card mini is a PCIe-based carrier board for the Raspberry Pi Compute Module 4, and by itself, it allows you to install a CM4 into a PC, and access the CM4's serial console via PCIe.

But the real power comes in 'sandwich' boards:

I'm testing Adlink's Ampere Altra Developer Platform. This machine has a 96-core Arm CPU, but now they sell a 128-core version. Apple also recently released the M2 Ultra Mac Pro, so the model I'm testing isn't the "fastest in the world" like I could boast a couple months ago... but it's close, and I actually doubled my performance from last time—I'll show how later.

Two years ago, Red Hat killed CentOS, a widely-used free version of their Enterprise Linux distribution.

The community of CentOS users—myself included—were labeled as 'freeloaders', using the work of the almighty Red Hat corporation, without contributing anything back. Don't mind all the open source developers, Linux kernel contributors, and software devs who used CentOS for testing and building their software. Also ignore the fact that Red Hat builds their product on top of Linux, which they didn't build and don't own.

This blog post is one of the few instances where, no matter how much you prefer reading to watching a video... you're going to want to watch the video.

The day after I interviewed Eben Upton, co-founder of Raspberry Pi, I went to the Sony UK Technology Centre in Pencoed, Wales to tour the factory where almost every Raspberry Pi has been made—50,000,000 of them (as of this month!).

I got to snap a picture with the milestone Pis:

Earlier this month, I was able to discuss with Eben Upton (co-founder of Raspberry Pi) the role RISC-V could play in Raspberry Pi's future (among other things—watch the full interview here).

If you're tired of waiting for Apple to migrate its Mac Pro workstation-class desktop to Apple Silicon, the Ampere Altra Developer Platform might be the next best thing:

I somehow convinced Ampere/ADLINK to send me a workstation after my now years-long frustrated attempts at getting graphics cards working on the Raspberry Pi. And they sent me a beast of a machine:

Every few months, I try to test a number of new Raspberry Pi Compute Module 4-based projects, and at this point I've looked at over 100 boards that use the CM4 to fill some need—general computing, industrial controls, media playback, or even clustered computing!

This month, among other projects, I spent a bit of time with Zymbit's Secure Edge Node D35:

KSDK-TV broadcasts to well over 1 million households in the St. Louis metro area. And my Dad and I went to their broadcast tower last month to explore how the digital TV signal is delivered through the air to so many people.

On our tour, we explored over 75 years of television broadcast history, seeing how things transitioned from thousands of volts down to hundreds, and from analog audio and video to all-digital.

And we even found strange artifacts of the past, like this random microwave dish that received a signal through the roof of the broadcast building for a time:

Today Raspberry Pi launched their new Global Shutter Camera.

Outwardly it is almost identical to the 12 Megapixel High Quality Camera, and like that camera it accepts C and CS mount lenses, or most anything else with the appropriate adapter.

But flipping it over reveals a black plastic cover over the back of the board that is not present on the HQ or M12 HQ Camera:

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.
