What does macOS or iOS think about YOUR dns server?

Context

macOS (MacBookPro18,2) and iOS (iphone 11 pro) claims the DNS service in my router is flaky, occasionally displaying a dialog accusing me of being offline.

not-online-supposedly

(no, this isn't MaxMSP for iPhone - just a youtube video, settle down...)

This doesn't happen often, but when it does, it's always just after a wake or unlock. The problem is more than cosmetic, though - when it occurs, I am actaully offline on that device until it decides that I'm online again. Usually it doesn't take long, perhaps because I generally don't take this news quietly... OR, maybe recovery is hastened by a background heuristic tasked with mitigating and sharpening the other heuristics, taking a page from the generative adversarial network design... Maybe that sounds far fetched, but I would certainly like to opt into "shake to over-r

One-liner to open the most recent video in your YouTube watch history
# This is for macOS, and requires that you have yt-dlp and Chrome installed.
# yt-dlp gains easy access to your youtube profile by borrowing cookies from
# Chrome, so you'll need to have logged into youtube with Chrome. The yt-dlp
# command will return the URL to the video at the top of your history, which
# can then be opened using your tool of choice - in this case, I pass it to
# 'open' to use the default browser.
# I use this primarily when I am (or was) watching a YT video on my
# Internet telephone, but then I want to pick it up on the mac.
# This technique is faster for me than anything done from the phone, even if

A somewhat brutal repair of Synalize It! Pro for macOS, which is broken by linking against the system-provided python which no longer exists.

check current python linkage

% otool -L /Applications/Synalyze\ It\!\ Pro.app/Contents/MacOS/Synalyze\ It\!\ Pro | grep Python
	/System/Library/Frameworks/Python.framework/Versions/2.7/Python (compatibility version 2.7.0, current version 2.7.16)

Download and install Python2.7.16 for macOS. By default this lands in /Library/Frameworks/Python.framework/Versions/2.7

Make a copy of the Synalize It! Pro app bundle, e.g. to your desktop.

cp -R /Applications/Synalyze\ It\!\ Pro.app ~/Desktop

The Powder Toy build produces malformed executable?

Working out of this repo: [email protected]:The-Powder-Toy/The-Powder-Toy.git

(base) andre@boom The-Powder-Toy % git remote -v
origin	[email protected]:The-Powder-Toy/The-Powder-Toy.git (fetch)
origin	[email protected]:The-Powder-Toy/The-Powder-Toy.git (push)

I had to change the SDL includes from two-level style to one-level style.
