Rich and Strange Aeons

The pricing of Philadelphia's bikeshare program is pretty weird.

One ride? A whopping $4.50 for 30 minutes; extra $0.30/min if you go over or use electric. Bus fare here is $2.50 and gets you free transfers.( Read more... )

A video yesterday reminded me of the Saudi Line proposal to build a brand new very linear city (or linear arcology, one long building) in western Arabia. I looked again at the numbers, and wow it is nuts.

170 km long.

500 m high.

200 m wide.

(Area 34 km2.)

It's supposed to be higher than it's long! Crazy. You could probably bring the cost down just by flipping those two numbers (though maybe ventilating a 500 m wide building would be a bit more challenging, I dunno.)

For minimizing trip lengths you would want a circular city, or something close like a diamond or grid. But I can see some appeal of a linear city: simplifying your high speed transport by needing just one backbone route, and keeping it easy to go outside the city into a greenbelt/preserve. (Not sure how much point to that there is in western Arabia, but anyway.) So I wondered what a saner proposal might look like.

1) drop the arcology and just go with a conventional city with streets and buildings.

2) Have the width be at least a 5 minute walk from edge to spine, so 400 meters, making it 800 meters (10 minutes) edge to edge, which avoids the need to have any cross transit. This is 4x the width, so could reduce the length from 170 km to 42 km. (Though the original proposal used the height to be very high density, which I'm kind of waving away.)

You could double the width, for a 20 minute edge-edge walk; 1.6 km x 21 km.

But since you're trying to avoid cars, you should go in for bicycles and other micromobility, at let's say 3x expected walking speed. 2.4 km edge to spine, and 4.8 x 7 km in shape... which is actually almost a square, whoops. And you'd probably need cross-transit again for the minority who can't use any form of wheels, or the larger group who don't always want to. Still, it's a city where every point is a 10 minute bike/fast powerchair ride to the central spine, at 15 km/hr.

San Francisco is actually bigger than this, so I've just discovered that SF could be way nicer than it is (granted SF has hills.)

To keep a line shape better, go back to the 10 minute width of 800 meters, triple it for bikes, now you have a 2.4 x 14 km city, and can get some real rail use out of your backbone, while it's still a 15 minute walk from the center to the edge.

Not that long ago, I read At Day's Close about pre-modern night and darkness in European light. I also have a recurrent interesting in low-tech 'fantasy' settings. All this got me wondering what candlelight is actually like, something I haven't experienced in a long time. Happily, I found that my host has 8 pillar candles in the basement, plus some long lighters, so nothing had to be purchased. ( Read more... )

1) A sloppy joe/picadillo. $1 1 lb fatty ground pork, $3 canned diced tomatoes, $1/lb whole wheat elbows, $2 4 slices of American cheese, plus onion and spices. Call it $8. Closest nearby equivalent is a quesadilla picadillo, that was quite good, but cost $14 (a fairly standard meal price around here), and probably had 1/4 - 1/2 lb of meat. So $8 at home, vs. $28-56 of takeout meals... Could be $6 at home, because with that cheap fatty pork, you don't really need the cheese.

2) I'm back to baking whole wheat sourdough. $6 for 5 lbs of whole wheat flour. After adding water, that's like 5 24-oz loaves of commercial bread costing $2.50 each ($12.50 total), or 7 1-lb loaves of artisanal bread costing $4-6 each ($28-42 total).

Are those fair comparisons? Well, I can't make anything like industrial sliced bread. Home bread is closer to artisanal. Probably not as good... then again, I don't think I've ever seen whole wheat sourdough in a store. There's refined sourdough, or whole wheat, not both.

When I moved here, I talked about getting a cheap non-stick egg pan again, so I could fry or especially scramble eggs with no cleaning effort. Avi said I needn't need one, that cast iron and stainless steel provided all the non-stick you need. I have slowly been converted, mostly. First I got fried eggs sliding off, but that's pretty easy. Then I found that simple omelettes worked well too: wait till it's a partly-cooked egg pancake, then fold. Finally, today, I did scrambled well. ( Read more... )

"Flu" in Scotland is so bad that many NHS doctors are voluntarily wearing masks, probably surgical face masks, to protect themselves, and suggested visitors do too. Let's count all the problems with this:

1) "so many​ doctors and nurses were falling ill ​from​ the virus that frontline workers were voluntarily wearing protective face coverings to avoid contracting the infection", 'described​ flu patients waiting for “hours and hours” to ​secure places on wards' -- despite all this crisis, no actual policy change for infection control, just individual mask wearing. Because apparently trying to keep your own workforce from being infected is too much for hospitals.

2) The article never mentions covid or coronavirus, despite the virtual certainty that many, if not a majority, of those "flu" cases are in fact covid-19. But hey, if you don't test, it's not there, right?

3) Three years ago, a British hospital did as close to a high-power controlled test as we're likely to ever get, basically proving that FFP3 masks are far more protective than surgical masks. (Quick summary: in surgicals, the covid ward workers got infected a whole lot, while non-covid workers only got infected at the community rate. In FFP3s, the covid workers got infected at the same rate as the non-covid workers and community.) Despite that, the doctors and nurses reported are likely wearing... surgicals. Certainly the blurry photo is only of baggy blues.

4) Reminder that influenza virus is easy mode. The same controls in 2020 that generally struggled with or outright failed to contain SARS2/covid-19, wiped out one or two entire flu seasons, with the B/Yamagata strain being wiped out by accident.

We have the technology. Mass respiratory infection is a choice, now. Our (across multiple countries) hospitals are choosing to permit mass infection. Our public health agencies are choosing to let infection spread without saying anything. Our health care workers are (mostly) choosing to get infected.

I've been facing the challenge of packing up all my stuff again. Compared to when I moved here: all my T-shirts are larger, which adds up in bulk and weight; I've acquired yet more masks; I invested in a second pair of jeans; I have an air purifier, bathroom scale, and folding bike, all of which I might want to take along.

Verrry late in the process it occurred to me to try to be logical/mathematical about it. This turned out to help less than I'd hoped. ( Read more... )

Where does this leave me? Still in indecision. I'd hoped the math would make it clear "ah yes, you should live minimally and walk away from stuff", but in fact there's a reasonable value proposition for maxing out my luggage, even with the extra taxi and baggage fees. At the very least clothes and bike, and not, say, "bring folding bike and buy new clothes". (Though I don't think single-luggage is even an option with this bike and current gear, I doubt it'd fit in my case without wheel removal, and maybe even with removal.)

Of course, the other consideration is some upper bound of willingness to deal with stuff. Even if bringing more makes sense as a $/lb measure, at some point I'm just done with extra pounds. But I'm not sure what point, yet.

On Bluesky a few days ago, some NYC people said that blacks were the demographic most masking these days. This surprised me, as I would have guessed Asians, from my own observations and vague memories of polls. Thing is, I feel gut level observations are pretty junk statistics, whether mine or someone else's, especially for anything complicated. ( Read more... )

They do work well, and are comfortable once on, but they're a huge pain to don and doff. Have to wrestle my shoe into the sole just right, then strap, zip, strap (and second strap is on other side, have to twist leg or attach it by feel). And getting the overshoe off without pulling my shoe off is difficult, I've only done it once in 4 times. Doffing my overshoes (and extracting the shoes) this evening took nearly 2 minutes.

I find it funny when I learn things from fiction, especially "lower end" fiction, such as when I learned a better way of cutting meat from a webcomic. Or when a yuri manhua introduced me to the idea of rain shoe covers: a girl saw rain, pulled covers out of her purse, put them on, and happily went splashing in the rain. This seemed neat, so I looked it up on Amazon, and found various options: disposable thin plastic that doesn't even cover the top of the shoe, more for indoor than rain use; disposable thin plastic that does go up higher, and might be appropriate for sticking in your bag for emergencies; less disposable rubber things.
