Learning how decrypt a drive when booted from a usb stick wasn't on my bucket let, but hey, it might come in handy later. initramfs is rebuilt, and laptop is again usable.

After many years of taking Ubuntu updates without thinking much about it, one of my Thinkpads just hiccupped. Attempting to reboot, cryptsetup waits for a bit, then dumps me in to busybox.

A quick search isn't turning up howls of pain from elsewhere, but does turn up some (old?) advise. Time to track down rescue media.

They way Merlin identifies birds by their calls is pretty slick. It does fast-fourier transforms, then uses image recognition on the resulting spectrograms.

Behind the Scenes of Sound ID in Merlin

What is Sound ID? Today we announced one of our biggest breakthroughs—Sound ID, a new feature in the Merlin Bird ID app—and a major leap forward in sound identification and machine learning

Fired up the Merlin app this morning and set it in a window close to the bird feeders. In ten minutes, Merlin (credibly) identified: chestnut-backed chickadee, house finch, american crow, anna's hummingbird, black phoebe, oak titmouse, lesser goldfinch, bewick's wren, american goldfinch, california towhee, spotted towhee, mallard, western bluebird, california scrub-jay, dark-eyed junco.

Notably absent: white-breasted nuthatches, who must have been put off by the crowd; woodpackers, who typically start in later; and mourning doves, who were quietly hanging around under the feeders. There were robins here two weeks ago, but they must have been passing through.

Thanks here go to the crows, who've been keeping the hawks away.

Realized too late in life that the offers of side quests that appear while I have a head cold, and defenses are down, are best deferred. Especially those that involve touching a keyboard.

Elapsed time from:

"I should probably clean out the coffee grinder."

to:

"Oh, dear God!"

about 15 seconds.

Noting a sudden resurgence of EDC and travel gadgetry in my feeds. A psyop from Big Vacation? Some of this gadgetry is cool, but taking advantage of it means booking flights.

"What is Correct?" and is that even the right question any more?

Of particular interest to those for whom Naur's, "Programming as Theory Building" paper resonates.

"SOC 2 For Individuals"

will not make it on to the list of good ideas my brain has coughed up at 2am.

The empty Waymo ahead of me demonstrated human-level judgement, making a well-executed, perfectly safe u-turn at an intersection that was very clearly marked 'no u-turn'. This in an area that Waymo trained in heavily for a year, so should be very well-representing in their training data.

I still trust their driving more than many humans on the road here.
