Anybody in Austin TX going to visit @microcenter for grand opening Friday? I'll be there; they're sponsoring my trip to work on a fun project with Patrick Kennedy / STH!

The main thing I learned at NIST last week (video coming soon!): you can NEVER have too many oscilloscopes :D
(And frequency counters)
Tektronix unveils low cost scope with 12-bit ADC and built-in Bode plots

And then you have me: Resurrecting the Smooth Jazz era WeatherSTAR machines such as the 4000.
Life goal achieved: visiting NIST-F4, the US's current primary frequency standard. I learned SO MUCH I didn't know about how UTC(NIST) is generated and distributed. I can't wait to share it in a video!
(Thanks to everyone at NIST who answered my time-noob questions!)
Tuning in WWV from St. Louis with my dad @radijoe for an upcoming @GeerlingEng video.
10/15 MHz fairly clear during daytime with MLA-30+ antenna and a HackRF Pro @OSSDRLab sent us for testing!
It is incredible to me how many people have authorized their AI tools to email on their behalf.
I now get 10-20 emails per day like this 😣
I feel Déjà vu.
(Remember to change your clocks if you haven't already! And say hello to your past self.)
There was a 30% chance for a negative leap second, because the Earth's rotation sped up. We've never had one of those before.
To save us from something likely worse than Y2K, the CGPM passed Resolution 5, killing the leap second early. More here: youtube.com/watch?v=vFMU2m-T…
At least in my mind, the actor I'll always picture as "the captain of the Enterprise". That character was also the reason I'm hooked on Earl Grey tea. RIP.

lol my lawn mower is only used 1x a week. Should I rent one from OpenAI instead?
Also, who caused the DRAM shortage? It wasn't consumers...
sam: local inference is a terrible allocation of scarce resources
“a lot of people want local inference, and somehow they assume that the problem is solved now because we have open-source models, we're going to be able to run them on our computers, and so we're not going to need all the stuff in the data centre
but from a global allocation perspective, actually it's quite terrible to have everybody, like, have a bunch of the world's limited supply of DRAM sitting in their own computer and being used five percent of the time
you want maximum utilisation in the cloud if you're trying to deal with this very supply-constrained environment
somehow many people's intuition is the opposite of that”
Neat watch I picked up to test time over RF. It's a NatGeo watch with Dakota's 'radio controlled' time tech. Fun to watch the seconds fly by when it acquired a signal.
Tiny coil antenna inside; I wonder how close I could take this to WWVB's antenna before it burns out...
I was sent one of these units and will be testing it.
Short preliminary thoughts: don't buy it if you just need a cheap scope—it's more for learning, and can do the basics.
The dual Pico architecture is interesting (and slightly quirky!). Full thoughts after more testing.
Picotronix is now live on Kickstarter!
A modular oscilloscope + logic analyser built on two Raspberry Pi Pico 2s. Programmable in MicroPython, fully open.
Start with the Main Module, then add picoPods as you need them:
- Analog
- Differential
- 12-bit waveform generator
- 12-channel logic analyser, 150 MSPS
- ADC-100: dual 100 MSPS ADCs, up to 75 MSPS on a stock RP2350
Early Birds are limited: picotronix.com/ks

It's been 12 years since I last updated Quick Resizer, a Mac App that... quickly resizes images.
I built it because I hated waiting 10s or so to launch Photoshop just to scale an image for my blog.
I let Claude fix 3 bugs and port it to Swift (under my guidance), and it's now hit 2.0, and works better than it ever did before (and waaaay faster on modern Apple Silicon). Plus it still runs on Intel, at least macOS 13+!
It's still $0.99 as it always was: apps.apple.com/us/app/quick-…
And now I can again stop launching Photoshop's monstrous husk of an app just to scale down photos for my blog.
Most interesting heatsink I've seen in a while. Found it while performing a Noctua fan swap on my Calnex Rb/GPS Frequency Reference. It's more like a porcupine than a heat sink!
Question for @CorridorDigital - any chance CorridorKey 2 could be built for Final Cut Pro X as well?

Update: I let Claude take a crack at it. Have not had a chance to test it, but looks like the complication is the plugin needs to operate on more than 1 frame at a time, so processing would need to go through a background server app: github.com/geerlingguy/Corri…

Last week's vulnerabilities found in PHP and Node.js (not to mention a separate certificate compromise) were a big deal.
I asked for @geerlingguy's expertise in my story for @radioworld_news that has takeaways for all online interests.
