According to BBC, there are now more Uber cars than traditional taxis in New York City. That happened fast. For now, there are still more trips taken by taxi. The article uncritically quotes traditional taxi advocates (without quoting Uber advocates) who think it is unfair that they are no longer allowed to jack up prices by limiting the supply of transportation available to people. They’re right, it’s no longer unfair in their favor.

The Setup
I like this blog The Setup, even though it is obviously trying to sell me stuff. This particular post caught my eye because I have fantasies very similar to this, and I thought I was the only one:
I have a dream home all built in my mind. I want to buy a big square warehouse with 4 floors, each wide open from wall to wall. If it was a city block that would be fine. I would open the first floor to the public and have a bar/lounge/music venue. It would be a labyrinthine layout and the decor would be all hacked and repurposed, upcycled and somewhat robotic – a mad scientist bar! This would help to fund the second floor, which would be a wood/metal shop and a stop motion studio. We would have plenty of room to develop inventions and churn out animation as well as concoct fun and entertaining technological novelties for the bar downstairs.
The third floor would be a sweet pad for artists in residency. I would pick and choose different people from all walks of life to come and offer their creativity to the entire process. If I want to make some crazy scifi dream come to life, I could invite several experts from a variety of fields and have them all working together on that idea. That would be absolutely incredible – better than a superpower! I think the third floor would also probably have airhockey and skiiball as well.
The fourth floor would be my sort of living quarters. I would have a big kitchen and movie theater and dining room and all that stuff. It would be totally sweet and only a select few would get to come up there.
The roof, though, is the really special part. The roof would be my bedroom. I would have a man-made hill, with soft grass, under a geodesic dome like the biodome. I would have fruit trees and a vegetable garden. My bed would be dug right into the side of the hill so I could sleep under the stars. But also at the top of the hill, I would have a platform on a pneumatic lift that would raise my super high-tech telescope up into the bombardier’s bubble at the top of the dome. It would be so cool! I could sit down at the desk and hit a button and ascend to the highest point in the building to stargaze.
Sounds pretty good. My fantasy actually involves a chocolate factory. Seriously, there is an actual abandoned chocolate factory a few blocks from my house in Philadelphia that has been sitting vacant for decades, and is now up for auction.
Now, people are saying it’s going to go for about $10 million, so I need to raise that. There might be some asbestos in there that will need to come out. Then the renovations can begin. On the first floor, I’m going to recreate Philadelphia neighborhood bars and diners that have gone defunct over the years, using actual materials from them if they exist, otherwise just recreated from photos. So you can wander through the different rooms and each one will be a different recreated diner or bar. At least one will be a coffee shop open during the day. Then on the second floor will be offices of my foundation, the mission of which has not been established yet, but of course will have something to do with sustainability and doing something good for the world. Dogs will be allowed. The third floor will be apartments for visiting scholars and other interesting people. But as I will be fabulously wealthy, I will also just buy a bunch of nearby houses that interesting people can hang out in, including one for myself of course. Hey, it’s my fantasy.
maternal mortality
I’ve talked recently about the happy statistics on child mortality globally – not only did it drop dramatically worldwide in the 20th century, but the progress has continued to be dramatic this century. Now, NPR has another happy statistic – moms are doing well too.
Since 1995 the rate of women worldwide who die in childbirth has dropped by more than 40 percent.
When you look deeper into that statistic, there’s even more reason to celebrate. Sometimes a rosy global health statistic can overstate the extent of change. A few large countries that improve their situation pull up the average, masking the fact that everyone else has stagnated or worse. But the maternal mortality rate has plunged by 40 percent or more in at least 76 countries — that’s close to half of the world’s nations…
Improving maternal health worldwide will require a heavy focus on sub-Saharan Africa, which accounts for 62 percent of annual deaths. Southern Asia is the other hotspot — a fourth of maternal deaths occur there.
worm bins
Making a worm bin is on my list of projects to eventually try. The one question I have always had is, once you separate the adult worms from the finished compost, aren’t there still worm eggs in there that are going to hatch?
kids and risk
I like the way Lenore Skenazy, author of Free Range Kids, talks about risk:
I think that we are thinking like lawyers a lot now because our society is so litigious, especially in America. For instance, one kid fell off a swing, maybe 20 years ago, broke her arm, sued the park district, and suddenly park districts across America started taking out high swings, they started taking out teeter-totters – see-saws – they started taking out merry-go-rounds. And so they started thinking like lawyers and then we started internalising the idea that, like, “Oh my God! It must be very dangerous for our children to do these things if they’re being removed from regular life.” And everything started seeming so dangerous that we sort of forgot, like, yes, some things are a little dangerous – you go on a merry-go-round, there’s a chance you’ll fall off, there’s a chance you might, your kid might break an arm. There’s also a chance they’ll have a fantastic time, they’ll lose weight, they’ll be fit, they’ll have something fun to do after school instead of just turning on the TV or going to the computer. But we always think in terms of the what if? worst case scenario, and that’s thinking like a lawyer. Because a lawyer could go to court and say, “We knew that these merry-go-rounds are dangerous! And why did they have one there? I’m asking you!” And we think ahead to that point and get rid of anything fun, even if the risk is tiny, because we think a tiny risk even is not worth it.
…in the same day that I’m saying children should go to the park, 769 children will be diagnosed with diabetes,” – that’s in the United States. That’s twice as many as 10 years ago. Nobody says, “How dare you let your child stay inside! What if they get diabetes?” Nobody says that. “How dare you let your kids stay at home just watching TV – they’re gonna get depressed, they’re gonna get fat, they’re not gonna have any friends, they’re not gonna have memories of their childhood.” Nobody thinks about the trade-off. Everything is straight to: you let your child have one iota of freedom, what if something terrible happens. They see the iota[?], they see the rape, murder and dismemberment and they try to put them together and of course it doesn’t work. What I’m suggesting is let your kids have the kind of well-thought-out freedom with you training them. Train them to cross the street, train them, “Don’t go off with strangers”, train them to swim. You know, I do think our job is to keep our children safe, but I don’t think that the outside is so unsafe that we have to regard it as Predators’ Ball every time you open the door.
I agree with most of this, except that the outside really is unsafe, not because of predatory humans but because of motor vehicles – you really can’t “train them to cross the street” safely because the streets are not designed safely. In reasonably developed countries that are not at war, I am positive that cars are the biggest source of violence against children. Of course at the present time we need to train our children to cross our unsafe streets as safely as possible. We also have to accept the risk that they can cross the street exactly the way we train them and still never come home. If we don’t want to accept this risk, then we can’t continue to accept unsafe street designs. Politicians and planners and engineers who perpetuate unsafe street designs, and all the rest of us who complacently accept them, are the real murderers and dismemberers of children. The solutions are known. This is a risk to children we really can do something about. Let’s do it!
ocean on Jupiter’s moon
Here is an article called Vast underground ocean discovered on Jupiter’s largest moon. Somehow they can tell by the way the planet bulges out that there is water underneath the surface.
NASA’s Hubble Space Telescope has the best evidence yet for an underground saltwater ocean on Ganymede, Jupiter’s largest moon. The subterranean ocean is thought to have more water than all the water on Earth’s surface.
This reminded me of Stanislaw Lem’s novel Solaris. About half that book is verbal description of an ocean on an alien planet. It doesn’t sound exciting, but I found it fascinating. This is a case where a picture is not worth a thousand words, because he describes these fantastical geometric shapes that you can picture in your mind’s eye, and yet they could never actually be drawn. It’s even more amazing that the book was written in Polish, and the version available in English is supposedly an English translation of a French translation of the original. Or maybe that has something to do with why the language is so fascinating. I wish I had a copy to pull out a good quote but I don’t have one at the moment.
Chinese “Crackup”
The Wall Street Journal is predicting the “crackup” of the Chinese government.
We cannot predict when Chinese communism will collapse, but it is hard not to conclude that we are witnessing its final phase. The CCP is the world’s second-longest ruling regime (behind only North Korea), and no party can rule forever.
Looking ahead, China-watchers should keep their eyes on the regime’s instruments of control and on those assigned to use those instruments. Large numbers of citizens and party members alike are already voting with their feet and leaving the country or displaying their insincerity by pretending to comply with party dictates.
I don’t find any of the evidence the author gives all that convincing. For example, part of his evidence is that people are traveling, investing, and studying abroad, while I wouldn’t consider any of those things unpatriotic. He interprets facial expressions at a party meeting to mean people are bored and insincere, but my own experiences trying to interpret facial expressions in cultures other than my own have been humbling. Finally, he suggests that restrictions on political speech are incompatible with a modern, innovation-driven economy. I think that may be true if “innovation” means truly creative system-based problem solving. But if it just means inventing new patentable objects that can be profitably sold, then I think narrow, highly specialized thinking may suffice, and the education system may be able to produce that without sparking a high level of political engagement.
the suburbs are dying
To my good friends still thinking about buying property in the suburbs – I don’t recommend it! According to Ellen Dunham-Jones, author of Retrofitting Suburbia; Urban Design Solutions for Redesigning Suburbs:
of the 1,100 shopping malls, one third are dead or dying. The 50,000 strip malls have a 11% vacancy rate. Within the 350,000 big box stores, 300 million square feet are vacant. However, you point out these dynamics have been around awhile, with the newest marker being the suburban office vacancy rates of 16-24%. What has changed to make these suburban offices less attractive?
There are several converging factors here. The one most frequently cited by CEOs is the need to relocate to the cities that are attracting the educated 25-34 year-olds that they most want to hire and who, for the most part, find the idea of working in a Dilbert-like suburban cubicle un-creative and toxic. Additional factors include the fact that computers have automated many of the clerical jobs that used to be done in the suburban back-offices at the same time that space/employee standards have significantly reduced. The wave of ’80′s office parks and corporate campuses are aging and increasingly out of date, while the cities have become immensely more livable than they were in the ’70s. So, we’re seeing the tide reverse itself as a wave of corporate relocate out of suburbs and back into cities and newly named “innovation districts.”
solar will be dominant
Deutsche Bank is the latest financial corporation to conclude that solar power is ascendant and fossil fuels are doomed. The research doesn’t seem to be free so we have to rely on press articles like this one. Perversely, it can be exciting when an amoral profit-seeking corporation tells you something you want to hear about the environment, because you know there is no agenda behind it.
homework
Surprisingly, serious studies of homework can almost never prove that it has any benefit at all.
And the result of this fine-tuned investigation? There was no relationship whatsoever between time spent on homework and course grade, and “no substantive difference in grades between students who complete homework and those who do not.”
This result clearly caught the researchers off-guard. Frankly, it surprised me, too. When you measure “achievement” in terms of grades, you expect to see a positive result — not because homework is academically beneficial but because the same teacher who gives the assignments evaluates the students who complete them, and the final grade is often based at least partly on whether, and to what extent, students did the homework. Even if homework were a complete waste of time, how could it not be positively related to course grades?
And yet it wasn’t. Again. Even in high school. Even in math. The study zeroed in on specific course grades, which represents a methodological improvement, and the moral may be: The better the research, the less likely one is to find any benefits from homework. (That’s not a surprising proposition for a careful reader of reports in this field. We got a hint of that from Timothy Keith’s reanalysis and also from the fact that longer homework studies tend to find less of an effect.[5])
This is hard to swallow. Obviously, from our adult life experience, most of us know there is such a thing as learning by doing. To really master a concept or come up with a new idea, you have to struggle with it on your own over a period of time. Homework seems like it could prepare children to do that as adults, so if it is not, either the kind of homework given is the wrong kind, or it’s given at the wrong age where kids are not yet ready to benefit from it.
