A window frame like this is a good way to test lens distortion and/or your post-processing workflow. As much as I hate it, Adobe Lightroom did a reasonably good job compensating for the lens distortion.

I keep some directories synchronized between my notebook and desktop with rsync. After upgrading my desktop to Mac OS 15.4.1, I started getting errors:

[sjg@BigThud 2025-04-21 13:01:05] ~/Documents/Backup
$ rsync -auP . sjg@10.3.2.xx:Documents/Backup
(sjg@10.3.2.xx) Password:
rsync: failed to set times on "/Users/sjg/Documents/Backup/Whatever": Operation not permitted (1)

Interestingly, ssh also showed an error:

[sjg@BigThud 2025-04-21 13:04:29] ~/Documents/Backup
$ ssh sjg@10.3.2.xx "ls /Users/sjg/Documents/Backup/Whatever"
(sjg@10.3.2.xx) Password:
ls: /Users/sjg/Documents/Backup/Whatever: Operation not permitted

On the desktop, I look again at Documents/Backup/Whatever, and the permissions are fine. What gives?

To make a long story short, something in the latest update on the desktop changed sshd‘s full disk access permission. Looking at System Preferences > Privacy & Security > Full Disk Access, sshd-keygen-wrapper was checked, so it should have been enabled. I tried toggling that, but it didn’t help.

Apparently, the sshd-keygen-wrapper was pointing at an old version or something? I had to go into System Preferences > General > Sharing and turn Remote Login off then on again, then go into System Preferences > Privacy & Security > Full Disk Access and re-enable sshd-keygen-wrapper.

Et voilà, I could ssh and rsync again!

I don’t want to use biometrics on my phone. There are a lot of reasons, most of them not very good for a nobody like me. Still, I like reading about OPSEC and thinking about it.

Biometrics are not revocable like a code. That may seem like a strange concern, but if, say, your fingerprint gets reproduced on the internet, there’s no way to prevent its abuse. People have 3D-printed fingers in gelatin with a captured image and gotten past phone fingerprint sensors. Many years ago when I was in the aerospace industry, we’d joke about the Russians “borrowing” your head if they wanted to get through the retina scanner at a secure facility. Again, do I have this kind of security requirements? No, but I still don’t want to use biometrics.

For the longest time, I couldn’t find the way to get Apple to honor my preference. I get a daily pop-up telling me to “finish setting up your phone.” Naturally, it pops up when I’m in the middle of a phone call and trying to do something with my calendar or something, and it gets in the way. Furthermore, it’s disrespectful. I don’t want to set up Face ID. Stop bugging me, Apple!

I used to be able to click into Preferences > Finish Setting Up Your iPhone and clicking the “Set up later…” button on each feature I didn’t want. Now there’s only an “Enable” feature. But it turns out that you can click the “Enable” and then “Cancel” when it asks for your passcode. This stops the nagging.

Apple has always thought they know best how you should be using their products. I’m finding it increasingly annoying. Why should each update turn on Apple Intelligence? I don’t want “AI” just as much as I don’t want biometrics.

I don’t want to go full Luddite, but maybe it’s time for me to start thinking more along the lines of a dumber phone.

I have always had a strangely strong relationship to places. It’s difficult to verbalize, but having a deep familiarity with a locale has been a fundamental way I relate to the world. This extends into mapping fantastic places I’ve read about upon the physical world.

For example, when I spent some summer months of my tweens on the Gulf Islands near Vancouver, the archipelago became Earthsea in my mind. Around that same timeframe, I lived near Altadena. When I “discovered” Tolkien’s works, Middle-earth started imprinting upon the local terrain.

The San Gabriel mountains formed an excellent stand-in for the Misty Mountains. In winter, the clouds sit on the peaks, in Spring, the “June Gloom” does the same, and in the summer, the mountains were nearly hidden by the swirling smog of the late 70s.

The area is filled with places that mapped across those worlds. There’s a windy road above a tributary to the Arroyo Seco that goes through forests of oak and deodar, and in the early evening when the sky grows dark the lights in the windows of houses on the lower slope twinkle mysteriously. It was exactly what Rivendell looked like in my mind’s eye.

As I’d read, local places would overlay. The craggy entrance to Colby Canyon with its guardian trees, the steep drop-off ridges around Mount San Gabriel, the rough-hewn tunnel just down the trail at Eaton Saddle, the rustic cabins among the bright streams and white alder groves in Sturtevant Canyon, the high forested ridges above Ice-House Canyon — all mapped to places within the Lord of the Rings for me.

Decades later, when the blockbuster movies came out, I opted not to see them. The images in my head and the mappings to places I know were too important to be overwritten by Peter Jackon’s vision.
