Current status: musing about crane operations on a day when it's too foggy to see the ground, relying on folks on the ground for feedback. I bet crane operators use this in similes for all kinds of situations.

two crane towers fade up into fog. A crane hook descends from the fog. You can hazily make out a crane counterweight at the top of the nearer tower.

I saw some sidewalk chalk art walking in #SanFrancisco yesterday morning.

At 20th and Irving, a skateboarding fire-demon-maybe by Kal Zakzouk.

At 4th and Irving, a mermaid by, I'm guessing, two collaborators.

sidewalk chalk art. zooming in on top left of the skater. she wields a lollipop overlaid with a faint mouse skull. her arms are perhaps tattooed or are perhaps Frankenstein-ish combinations of things.

This morning's mystery solved: Did someone seriously take the time to point out some dangerous wet ground on a path in the park? Oh, wait, apparently a recent Hash House Harriers (very un-serious follow-the-leader-playing running club) run, in addition to the usual trails for Eagles (speedy runners) and Turkeys (normal runners) had a separate way for Walkers. chalk marks on pavement: "↑ WET". More subtly, there is a clump of chalk dust nearby

I continue to check my little dashboard of #SanFrancisco COVID numbers each morning to figure out whether shopping for groceries in person is a good way to get the best produce or the kind of eventual-lung-problems risk that I'd be embarrassed to discuss with my doctor in a few years. Lately SF's COVID-in-wastewater numbers have been sneaking up. You'll recall that I track three statistics; when their combo gets high, I switch to getting my groceries delivered and such. Just one number's a little high; so I'll keep picking out peppers in person, but with a perhaps less-carefree mien.

graph charting three numbers over the past two months. The purple line, test positivity%, was high a couple of months ago, but is now pretty low. The red line, new cases, was low a couple of months ago, and is now even lower, yay. The green line has jiggled and wiggled high and low over the last couple of months; lately, it's been high-ish

Some pics from walks in #SanFrancisco the past few days.

View of UCSF Parnassus from Irving Street. I wondered why one building's lights moved funny as I walked; and that's because it's not a building yet, still a construction site without walls. I guess I should snap a photo now, since in a few months it will look quite different.

Some soap bubbles clinging to leaves let me know I'd missed the Golden Gate Park sea serpent Naga's exhalation by a few minutes.

Some chalk marks clinging to the sidewalk let me know I'd missed a Kal Zakzouk artwork by a few minutes' worth of rainfall.

A new mural's going in on the public housing building at Haight/Stanyan. It's not visible from many places, kinda hidden behind buildings.

in the foreground, a retail street. behind, dimly-lit big buildings on a hill; when you peer more closely, you notice the one on the right is under construction. above the buildings hover some cranes, confirming that construction's going on. in the very background, colors of sunrise

bright green leaves. at first you might think there's a bright blue strangely-shaped flower resting on the leaves, but when you look more closely, you see it's a soap bubble reflecting something bright (the sky?)

patch of sidewalk with hints of color, where chalk has mostly washed away. Most legible is a partial signature @zakikal...something

hemmed in by other buildings, we see a mural taking shape on the eastern exterior wall of the new building at Haight/Stanyan. The mural has clouds styled as in an old-timey Chinese painting, sunflowers, poppies, rainbows. Some purple geometrical designs with 8-way symmetry. It's pretty bright and colorful

Some chalk #StreetArt, I assume by Kal Zakzouk, at 20th and Irving in #SanFrancisco yesterday morning.

there's a lot going on here. inert human figure is somehow connected to various spiritual bits: arms performing mudras, demon head, antlers,… Uh, it's a lot

Some things I saw on my walk in #SanFrancisco this morning.

The simple geometric-form murals have been up at the new public housing building at Haight/Stanyan for a while, but I finally noticed the piece of paper that says they're the work of Jenifer Wofford et al. Looking at her web site, I think most of her work tends to depict real-world things instead of geometric abstractions. I'm guessing that the public housing folks, tired of listening to the local poor-people-hating neighbors' complaints said, "Please give us the most unobjectionable design you can." Anyhow, check out her website for not-so-abstract stuff.

A geometrical construction rendered in sidewalk chalk near Hippie Hill.

A fork in the path at Heroes' Grove on a foggy day.

wall with mural consisting of different-colored circles on a background of a geometrical regular wave. Below, some still-under-construction pavement and a traffic cone. To the side, a window with a little piece of paper; if this image were higher resolution, you'd see that the paper tells you that Jenifer Wofford and others made the mural

in the foreground, a sidewalk wiggles between a field and a grassy hill. drawn on the sidewalk in colored chalk are some circles and arcs which form a hexagonal construction suggesting triangles. in the background, trees obscured by thick fog. really thick fog. would you believe me if i told you there's a dog and a dog-walker back there?

fork in a path among redwood trees. the path is 'paved' with wood chips and needles. looking up, you can see the treetops, but they're kinda obscured by fog

Milestone: 50 Million Hits

Wow, it's the site's 50 millionth hit. These "hits" aren't a measure of humans visiting pages; that count would be much lower. It's just requests to the website: every time a robot visits some page, the count goes up. If a human views a page that contains a dozen graphics, those graphics cause another dozen hits. So "a million hits" isn't as impressive as it sounds. But hits are easy to measure so that's what I measure. We can take a look at the log:

68.221.75.24 - - [05/Nov/2025:16:34:02 +0000] "GET /frivolity/prog/phraser/words_500K.txt HTTP/1.1" 200 6452256 "-" "Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko); compatible; ChatGPT-User/1.0; +https://openai.com/bot"

Ah, it looks like a bot is reading words_500K.txt, that long list of words I use when writing and solving word puzzles. This bot says it's from openai.com, the ChatGPT company. If I look up the 68.221.75.24 address at the beginning, I learn that the machine making this request is running on Microsoft's Azure cloud. Or it could be a bot from some other company running elsewhere; that "openai.com" and "68.221.75.24" info is fake-able. That's something you read about on the socials, these days. Some web-publisher gets annoyed at a bot from an AI company, and blocks it; just to notice that requests start coming in seemingly from other organizations running on some other cloud…but that data is fake, it's just the annoying bot trying to be sneaky. It's easy to understand why a web-publisher might get annoyed; some of these bots are pretty stupid. If your memory is amazing, you might recall some months back when I posted about this site's 47-millionth hit, it was a bot checking to see if I'd added a little graphic (I hadn't.), which it re-checked 2000+ times over the course of that day. At the time, I wrote "Of yesterday's ~8500 hits, ~2800 of them (about ⅓) were this stupid bot checking for the favicon. 'Has Larry updated this one thingy in the past 30 seconds? Better check! Nope, no change! Well, better get ready to check again in another 30 seconds!'"

When I looked at yesterday's logs to pick out the 50 millionth hit, I saw it was openai looking at words_500K.txt; and then my eyes looked up and saw that the previous hit was openai looking at words_500K.txt; and then my eyes flicked down and saw that the next hit was openai looking at words_500K.txt. I search the logs: Of yesterday's ~15000 hits, ~5000 of them (about ⅓) were this stupid bot checking words_500K.txt. I update that file a couple of times a year, but OpenAI's stupid crawler-bot checks three times a minute.

It occurs to me that a lot of these AI companies are maybe using AI to write their computer programs. Thus, they might have a lot of darned-poorly written computer programs. Maybe that's why their crawler-bots re-check unchanging web pages so enthusiastically? Anyhow, welcome to the site, bots and humans of varying levels of sophistication. Enjoy your read.

I continue to check my little dashboard of #SanFrancisco COVID numbers each morning to figure out whether ducking into a little shop to get out of the rain is sensibly staying dry or likely to be an embarrassing thing to bring up with my doctor when discussing the risk trade-offs that led to my hypothetical long-term lung problems. Lately, all three numbers that I track have been looking good! The last time I posted, two of the numbers looked good, but the wastewater-number still looked high. But it's come down since then, whew!

graph charting three numbers over the last couple of months in San Francisco: # of positive (sick) PCR tests, % of positive PCR tests, and COVID in wastewater. Lately, all three numbers have been low, yay

Guess I'll try to stay dry.

After many attempts, yesterday I finally got to see Naga blowing bubbles.
