PTP, NTP, Sync-E, GPS, PPS... the Switchberry does it all :)

A Raspberry Pi-powered managed Ethernet switch built specifically for timing applications. I used it to finally get all my clocks in sync, quick video with bonus Wireshark sniffing! https://www.youtube.com/watch?v=wxFHw57XGjA

The movie 'Fall' has a radio tower in it. Don't let a radio engineer see it 🫣 https://www.youtube.com/watch?v=WGzruDpVX-Q

Kicking off #MARCHintosh with the smallest Mac ever: the Pico Micro Mac!

Did you ever have a day where you have one task.

And you open up the app, open the file...

Then spend 8 hours on a completely separate task, and wonder how it's already 5 pm?

(At least I got this particular clock down from 37 seconds off to 200ms off...)

re @claudeai@threads.net

I've identified industrial-scale copyright violations on my content by Anthropic, OpenAI, Google, X, and more.

These companies created thousands of crawlers incorporating the text of all my blog posts, open source code, and books into their paid AI models to profit exorbitantly.

The madlads at Pimoroni overclocked an RP2350 microcontroller from the base clock of 150 Mhz to a whopping 861.6 MHz.

It looks like 400-500 MHz can be stable on most Pico 2s, which is still wild.

Exaviz mini NAS/NVR CM5 board - includes 8x PoE, 2.5 Gbps uplink from Pi. Fits in a 10" mini rack, with an enclosure (not final version) from DeskPi. Testing it next week!

Can a robot replace my parent-child interactions? It should be "utterly trivial"... but I found that not to be the case. The robot is still cool, though. Full video here: https://www.youtube.com/watch?v=yvBbcLCZIhg

Prepping for #Marchintosh...

Why does every clipart illustration Google use look so... weird.

Like this one for "No content available" in YouTube Studio looks like a cigarette sitting up against a flower

When I think of what electric car UX could be, this is more of what I think of, not "one giant touchscreen" and some capacitive touch buttons

Jony Ive understands iPhone UX (a slab of glass with no buttons) does not belong in the driver's seat.

This monitor is ridiculous. So I plugged in my Quicksilver G4 and tested the limits of early 2000s VGA in 6K :D https://www.youtube.com/watch?v=yPQbfD32V2k

OpenClaw (which was Moltbot, which was ClawdBot, all in the course of a week) is the new `sudo curl | bash`

A good time to ensure you have a stable holdover clock, and a way to switch NTP servers in case the one you rely on is down.

But this is rough, losing power to the clocks that make time for US services... https://groups.google.com/a/list.nist.gov/g/internet-time-service/c/o0dDDcr1a8I
