@daringfireball I don’t get how YouTube gets away shipping an app without PLAY/PAUSE button working. Need to push the middle button to resume.

Peacock is the worse. I’ll pause a video, go off to do something and hear my movie resume 10 minutes later from across the house.

over a year ago, i gave a talk at the xoxo conference about a mural, a mcdonald’s, and a man. (but it was also secretly about life, and legacy, and meaning.)

finally, i’m blogging the full story, with behind-the-scenes details, and a video of the talk.

i hope you enjoy this read. https://cabel.com/wes-cook-and-the-mcdonalds-mural/

Wes Cook and the Centralia McDonald's Mural

A personal story about discovering a mural in a McDonald's, an unknown artist named Wes Cook, trying to save the mural, and a conference talk about it all.

I’ve been tinkering with the ADALM-Pluto the last few months. Claude and I put together this multisite multi band spectrum management tool.

@geerlingguy I built a small program to translate the Time of Day signals from an old HP GPSDO to chrony! It works fairly well on the CM4. I think it stayed within 10 ns of gps time.

@poleguy i have this snippet in one of our systems. It’s so dumb and so cool that it just works like that. No drivers!

@marioguzman I waited in line on release night to buy a $129 DVD!

lldp-bar is another small tool i've been working on. This script puts LLDP/CDP info right in the mac menubar.

It's been great for field work. I don't always have a LinkRunner on me, lldp-bar makes it easy to identify ports/switches for troubleshooting and configuration.

I've been working on chrony support for some old HP GPSDO lab gear.

I created a custom PTT microphone for Shure wireless systems. Tune in next week to watch me turn an old cable modem into a spectrum analyzer!

@film_girl my mom still uses an iPad Air 2 from 2014! Can’t get her to upgrade, still does everything she needs it to do.
