Raspberry Pi has a new AI HAT. This time with built-in 8 GB of RAM, so you can run machine vision + LLM inference all without touching the Pi's CPU. It's $130 and a little bit of a niche item. Find out why in my video: www.youtube.com/watch?v=jRQa...
Look! More AI stuff!

Hosting websites was so much easier back when I didn't have to consider AI scrapers, malicious actors, etc.
It was more fun getting /.'ed and seeing things fall over than having to be able to handle a terabit of traffic in a sudden deluge multiple times a month.

So far since posting my video on the 1U rackmount Pico GPS clock, I've tested 0.08, 0.12, and 0.20mm thick filament "lenses" (pictured below), a tinted plastic tape, kapton, and car window tint.
Interesting findings; do you think it's worth a follow up on L2J?

The Mono Gateway is a 10 Gbps router with dual SFP+ ports that fits in 1U in a mini rack. It's custom-built for open source Linux router software like OpenWRT, and I tested its throughput on @ServeTheHome's $1m CyPerf server!

For the last video of the year, I tested Dell's "Dell Pro Max with GB10" (rolls right off the tongue, that).
Dell sent two and mentioned they aren't gaming boxes, so maybe don't focus on that in a review. So guess what I did first ;)

Here's the wash cycle of my broken Bosch 500 series dishwasher.
It's fixed now (pump was making grinding noises and was very weak), but this is like strike 7 for this dumb appliance.
Might have to make another video about it sometime.

to save any of y'all trying the new @jeffgeerling.com super rdma jaccl magic and you only have the thunderbolt 4?
don't bother, you need thunderbolt 5.
however you can still use ring mode though, which as you can see isn't so shabby at 37.9 Gbit/s of old fashioned TCP over thunderbolt 4!
