You know what I miss about CDs and other physical music media?

Liner notes.

Art, lyrics, sometimes stories…

…and credits. Who is that familiar-sounding background singer? Who wrote the song? Is it a cover? This one really reminds me of a certain composer, lyricist, or arranger’s style – can I confirm that?

The performer and title are easy to get, even if it’s not in your own library.

But the rest? If the song is notable enough for Wikipedia, great. Otherwise, who knows?

(This post brought to you by trying to figure out just how many songs on a Bonnie Tyler compilation were written by Jim Steinman.)

Tiger staring through a chain link fence

The tiger was a lot closer to the fence than I expected, watching us tourists with a disdainful look as it lounged in the afternoon heat. The fence mostly blurred out of view, but I didn’t notice a dry leaf in front of its face to the left of its mouth, leaving a brown splotch in the camera’s view. The tigers at the San Diego Zoo’s Safari Park have quite a bit of space, and this isn’t the only shade, which makes me think they were people watching. It’s an intriguing thought. And a disturbing one!

Looking at the photo reminded me: Tigers and other large cats have round pupils, unlike housecats. I read an article a while back on a study that linked pupil shape to ecological niche: Horizontal pupils mainly appear in prey animals (sheep and goats, for instance), and vertical pupils appear primarily in ambush predators who are active in both day and night, and whose heads are low to the ground (like snakes and smaller cats). Horizontal pupils handle glare better and offer a wider visual field. Vertical pupils adjust to a greater range of light levels and, by narrowing the depth of field, offer better distance cues…but that effect is stronger when your eyes are close to the ground. Higher off the ground, the vertical slits don’t help as much, so bigger cats like lions kept round pupils.

Expanded from a post at Photog.social. More photos from trips to the Safari Park in this Flickr album.

Twitter is suited for short statements and back-and-forth conversation.

It’s terrible for anything long-form.

Long Twitter threads* and images filled with text remind me of the old tech support days when users would paste screen shots of error messages into Microsoft Word documents and email me the document. It was a terrible tool for the job, but it was the one they knew.

Once you get past two or three tweets (doesn’t matter whether they’re 140 characters or 280, it’s the structure that matters), your ideas will hang together better and be better understood if you write an actual article somewhere. Sadly, Twitter has trained people to stay in Twitter instead of going outside to read the %#$ article**, because you won’t be able to get back to where you were in your timeline, and besides, that’s just too long to read right now.

And that would require you to have, like a blog or something, and what sort of weirdo has one of those? 🙄

So people use what they know, and we get screenshots of long paragraphs that are awful for accessibility. And we get 40-tweet threads that people only see fragments of and take bits out of context. And they’ll reply to tweet #5 complaining about something that’s addressed in tweet #12, but they didn’t see it, because that was hidden behind the “read more” link, and how long does this thread go, anyway? (Scroll bars solved this problem decades ago.) And we get links to articles that people don’t read, but they reply to them anyway — or rather they reply to what they assume was in them.

Which I suppose is what we had in the old days, I mean “nobody reads the articles” was a joke on Slashdot 20 years ago. But it’s still frustrating.

Update: I realized I don’t see this so much on Mastodon. I wonder if that’s one of the ways the culture is different, or if I just happen to not be following anyone who writes/boosts long threads on a regular basis, or if 500-character posts give people enough room to breathe that they don’t feel like they’re already writing a long chain, so why worry about keeping the number of posts down, what’s the difference between 10 tweets and 15?

Update March 2024: Apparently it was a posting culture thing, because it’s common on the Fediverse now too. At least on platforms like Mastodon that maintain a smallish size limit.

*To clarify, I’m talking about long threads that are effectively one piece of writing, not a series of “oh, and another thing” follow-ups, live-tweeting as things come up, actual conversations, etc.

**This part is true of Facebook as well.

Imagine a dangerous road curve. Do you blame the drivers and call it a day? After all, not everyone crashes over the edge or into oncoming traffic.

Or do you bank the turn, calculate a safe speed limit and add a railing?

It won’t stop all crashes, but it’ll reduce them.

Re-engineering the road doesn’t ignore the driver’s decisions, but it acknowledges that they don’t happen in isolation. Change the circumstances, and you change how many drivers crash and burn.

Thin clouds and contrails cross the sky. A bright rainbow-like ring circles a spot just out of view above the frame. A fainter rainbow-like line runs across the sky below it.

Two solar ice halos spotted at lunch today.

The 22° halo around the sun is really bright and clear, and not that uncommon even in Los Angeles. I’ve seen so many that I still take photos, but I often forget to post them unless there’s something unusual about the view.

The circumhorizon arc below it, on the other hand, I’ve only seen a few times, usually fragments. It’s faint, but it’s the longest and least wispy of these arcs that I’ve seen (though the best was probably this one from 2010).

The lower one could be an infralateral arc. It wasn’t quite long enough to tell in person whether it curved upward or was parallel to the horizon, and it’s hard to tell how much of the curve in the photo is due to lens distortion. But according to Atmospheric Optics, they’re a lot rarer than circumhorizon arcs.

It’s cool to be able to get pictures of these with my phone. There was a time I’d run to get a camera and hope it wouldn’t fade first.

Saturation enhanced. It was really hazy!
