Someone's trying to get Nvidia GPUs working on a Raspberry Pi by running x86 VMs and passing through the PCIe devices on the hardware level hacking the Linux kernel IOMMUs... ...and I'm here for it! github.com/geerlingguy/ra…

Even basic CAD skill is a minor superpower. Making something exist that you want to exist but doesn't yet exist, is very cool. I was tired of my shopping bags flailing around my trunk, and cargo covers can't get things drilled into them. So I made this: printables.com/model/1403210-…

I've had a Xerxes Pi for testing, and also backed it on Kickstarter. Regular crowdfunding caveats apply, but this is an interesting alternative to the Compute Blade for CM5 (and potentially other CM) 1U blades... 7 hours left on KS, but no guarantees! kickstarter.com/projects/19076…

I'm preaching to the choir here, and it will never make YouTube change, but can I just say how much I *despise* a shorts carousel now being the top spot of my Subscriptions feed in the YouTube app—and it can't be disabled, even if I tap the dots and say 'don't show this'?

People ask me why I don't do more testing with Nvidia Jetson. I think the reaction to the (overpriced) DGX Spark is a good illustration. Costs too much for what it does, alternatives are better supported and faster at a lower price point, and you don't get stuck on an old OS.

#homelab learning for the week: for actually-critical racks, have an AC transfer switch in front of any UPS, since UPS battery replacement will likely require some downtime, even if just for re-calibrating for new batteries. (Redundant PSU even better but not always possible.)
