City of Cambridge weighs in on the Indian question

In local news… “‘Real Indian’ challenging Elizabeth Warren must remove signs calling her a fake Indian, city [of Cambridge] says” (Miami Herald) is fun:

“Only a REAL INDIAN Can Defeat the Fake Indian.”

The words, emblazoned on two signs that hang off U.S. Senate candidate Shiva Ayyadurai’s campaign bus, appear next to two images: one of a stoic Ayyadurai looking into the camera, and another of a closeup of Massachusetts Sen. Elizabeth Warren wearing a Native American headdress.

So you can say whatever you want in Cambridge as long as you have a permit from the city for a sign on which to say it and you need the permit whether the sign is attached to a building or hanging from a vehicle.

The Sky Below (book by an astronaut)

The Sky Below: A True Story of Summits, Space, and Speed is Scott Parazynski’s account of day-to-day life as an astronaut, plus some mountaineering stories.

It turns out that being an astronaut is bad for your health, even if the rockets don’t blow up. Spending time in a zero-g environment leads to permanent back problems:

my multiple spaceflights and spacewalks mean the likelihood of spinal trouble is almost as inevitable as an overloaded, rickety Jenga tower toppling over into a ragged heap. In space, the spine straightens and the intervertebral discs swell when not being compressed by gravity,

So don’t be too envious when your friend gets accepted by NASA and you don’t! There are minor issues as wel…

In space, astronauts often develop facial edema or swelling, associated with a mild runny nose and headache, because gravity no longer pulls blood and interstitial fluid into the legs as it does on Earth. Conversely, astronauts appear to have “bird legs” with this redistribution of fluid into the central blood circulation, accompanied by a 10 to 30 percent decrease in leg circumference.

Another serious danger is decompression sickness, or the bends, something I was very familiar with from my scuba diving background. If the pressure inside the spacesuit isn’t managed properly, going outside into the vacuum of space could cause nitrogen gas bubbles to expand inside an astronaut’s blood vessels, causing severe pain, cramping, and even paralysis or death. Higher suit pressure decreases the risk of decompression sickness, but lower suit pressure increases the astronaut’s flexibility and dexterity. Like a deep-sea scuba diver doing decompression stops to prevent the bends, astronauts must purge nitrogen from their bloodstream before going outside, accomplished by breathing 100 percent oxygen. The oxygen and other critical systems of the suit are housed in the Primary Life Support System, which resembles a large backpack.

The author is a physician so the book is strong on space medicine.

The author participates in a famous repair to a photovoltaic array that powers the International Space Station. Try searching for some videos of this seven-hour space walk!

As tough as the space walking is, the author describes climbing Mt. Everest as yet more difficult (similar risk of death as well). Two attempts on the mountain, the latter one successful, are describes in the book.

The book describes the author’s formative years. His father was a sales executive at Boeing. Iran looked promising in 1978 and the family was sent there for a one-year assignment:

But three days after we arrive, the country erupts in revolution. September 8, 1978, marks Black Friday, a massacre in the capital city’s Jaleh Square.

Optimistically betting on a quick and peaceful end to the protests, Dad goes to work at the Boeing office selling aircraft in the Middle East and I enroll in the twelfth grade at the Tehran American School, home to 1,059 high schoolers.

In December we receive notice that our 5,500 pounds of household goods have finally arrived from Athens, and Dad arranges for delivery on December 23. We move into a nice but compact rental house in a walled compound, but sometime that month, Dad finds a note on his car. Die, imperialist pig. You have one month to leave the country or we’ll kill you.

Dad feels sure the Shah can put down the insurrection with his substantial army, and he wants to go back and do his job, looking to the promise of a bright future.

In other words, what we think of as the inevitable political and religious trajectory of Iran did not seem inevitable at the time, at least to a foreigner.

The author’s personal life contains some challenges:

by fifteen months, Jenna starts to fall off the developmental curve. We notice she is easily agitated and incredibly noise sensitive, prone to intense, inconsolable tantrums. She doesn’t like to be comforted, or even touched. When she is two years old, after my return from STS-100, Jenna is behind in language development, doesn’t seem very interested in people (including us), and lives in an almost constant state of agitation.

At just over two years of age, our daughter is diagnosed with autism spectrum disorder,

Jenna’s diagnosis and the ongoing struggles put a heavy strain on our marriage. For a time, I mourn the loss of my traditional hopes and dreams for Jenna, realizing she might not ever achieve a fully independent life, have a career, get married, or have children.

The author is candid about getting a “divorce,” though the term under Texas family law means something completely different than in California or New York. The financial damage is minimal (Texas caps child support profits and alimony is not generally available for a working spouse such as the author’s). He says that being an astronaut takes a toll on relationships and divorce is therefore common, but he does not look at the role of no-fault divorce laws. Explorers in the 19th century would go away for a year or two, still be married after their return (if they returned!), and then stay married for the next few decades. With on-demand divorce, would their partners have decided to stay partnered?

Once free of the wife with whom he does “not see eye to eye,” the author is quickly united with Meenakshi Wadhwa, a professor at ASU with whom he works (apparently it isn’t a #MeToo situation if the woman thinks that you’re tall, good-looking, and fit…).

Let’s hope that the ex-wife isn’t reading this book:

I pour out my heart to the most remarkable woman I’ve ever met. I thought soul mates only existed in Meg Ryan movies, but here is a woman who shares my great passions in life, accepts my weaknesses, and who brings out my very best. We are dreamers who never dreamed we’d find each other. Somehow, the universe brought us together through Earth, space, and ice. And I am never going to let her go.

They’re both on government-paid trips to Antarctica at the time of the proposal. Being a scientist has its perks! (but the childless status of Professor Wadhwa suggests that there is a price to be paid, especially for women)

Why are the rest of us such underachievers by comparison?

Most dreams are left on the pillowcase, unfulfilled. Dreams without a plan and a purpose get left behind in the rush of daily life. I get it; I have many dreams still on the shelf, and I learned early on that the pathway to success is long and arduous, and giving up can be tempting as hell. But I have learned how to dream big and then set course to make it happen. I’ve learned the essentials: keeping laser focused, visualizing the path to success, maintaining a strong support network, training for success but preparing for failures along the way, and having confidence tempered by humility and a dose of luck. If you are ready for the call of opportunity when it rings, and you are willing to put in the work required, it’s remarkable how dreamlets emerge, tangible, from the fog of unrealized dreams. It’s really not all that hard if you aren’t afraid to stumble every once in a while and then get back up. And back up. And back up again. The summits and calderas and skywalks and other bold life challenges are out there, waiting for you to dust off your dream. Everything is possible until proven impossible, and then you just need to become more creative. The sky is not the limit. And it never will be.

We need a dream and a plan!

Virtue lessons from our Silicon Value superiors

From a group chat… “Sheryl Sandberg Talks Paid Family Leave, Community Organizing, and Cambridge Analytica”:

It’s not enough to have the policies, you also have to use them. I’m really proud that Mark [Zuckerberg] took paternity leave. He sets the right example. Our CTO took paternity leave, our chief product officer took paternity leave. One of the most important things we need to fight is the idea that this is a female issue. This is an issue for families and if we want mothers and fathers to be equal parents in the households, we need to start out equal. And that’s why equal paternity leave is so important. We give four months to both [mother and fathers] and we really encourage people to take it. Another thing we found is that flexibility in how you take the policies works. We offer four months over the course of the first year. And that really increases participation, especially amongst men.

Friend’s comment:

Mark Zuckerberg took paternity leave so his stay-at-home wife could continue to provide for the family while he took care of the baby

I wonder if these multi-billionaires actually can set examples for the rest of us. It is nice that Mark Zuckerberg could take some time off while the childless workers at Facebook had to stay at their desks in order to get paychecks so that they could pay the rent, but he could also take the rest of his life off if desired.

Separately, the article gives some insight into the future of politics on Facebook:

Do you still see Facebook as a viable tool for activism?

Sandberg: I think [Facebook is] a critical tool to organize around issues. A bunch of the Parkland March [for Our Lives] was just organized on Facebook. Some of Black Lives Matter was organized on Facebook. Facebook is a critical way that people communicate and we’re really proud of the role Facebook plays in social mobilization. The Women’s March was [born from] a [Facebook] post a woman did. She said, ‘What if people march?’ She woke up the next day and there was a Women’s March. That doesn’t mean there haven’t been things on Facebook that we don’t want to have happen on Facebook—and we’re taking strong steps to correct that—but as an organizing tool for people who are trying to reach communities, it’s huge.

Readers: Do you think that these stratospherically wealthy and powerful Silicon Valley folks can be role models for ordinary schmucks? If Mark Zuckerberg does something, will Joe or Jane Average try to do it too?

Service to upload and print photo quality from PDF files?

I have organized some photos, with captions, into PDF files (8.5×11″ paper size). The standard photo printing services, such as Mpix, will print 8.5×11, but they won’t accept PDF files as uploads (maybe because it becomes too hard to print when multiple pages may be printed?).

I could do this with home inkjet printer, right, onto glossy 8.5×11 photo paper? But all that I have currently is a “near photo quality” laser printer.

Isn’t there a service bureau that will accept PDF files, a credit card, and mail the resulting print-outs? Or can this be done at a FedEx/Kinko’s or Staples?

Why isn’t this something that a lot of people want? Everyone wants photo printing from JPEGs, right?

Technical means of preventing cars from hitting pedestrians en masse?

The news from Toronto is not good. I’m wondering if there are reliable technical means, short of hacker-proof self-driving cars, for preventing modern vehicles from being used as weapons.

No modern car will run without the computers that time the ignition and fuel injection, right? So it should be possible to have the engine control computers refuse to continue running the engine unless they are getting a signed “everything is great” signal from a tamper-proof computer/sensor system?

Our 2018 Honda Odyssey tries to sense some bad situations, e.g., an impending head-on collision. Unfortunately, it seems to panic every 20 or 30 miles when driven on two-lane roads, thinking that a car in the opposite lane is on a collision course.

There are already cars, however, that will hit their own brakes if you’re about to run into a pedestrian, right?

What about a system where the car or van can sense that it has departed from the road and is now on a sidewalk? The result would be limiting the vehicle’s speed to, say, 3 mph.

Obviously there are a lot of older non-compliant vehicles on the roads, but a country that was serious about preventing these kinds of attacks could simply export all of the legacy vehicles and insist that everyone buy a new car.

Or is the whole idea bad in light of the impending self-driving vehicle revolution?

Boston Opera Collaborative La Bohème: should opera be presented in smaller venues?

The cultural highlight of our spring here was the Boston Opera Collaborative La Bohème. Part of what made it so great was the comparatively small venue, a craft brewery in Jamaica Plain. Instead of thousands of elderly people falling asleep there were about 60 audience members, at least 20 years younger than the median age for the big opera houses.

The orchestra was small, but didn’t sound thin. (conductor: Beatrice Jona Affron) We have supertitles on flat-screen TVs. The acoustics were remarkably good. Maybe if the hall is small the engineering constraints can be relaxed?

Being so much closer to the singers it was possible to appreciate their acting and also understand more about the technique. The audience was visibly far more engaged than at a big opera venue.

As the audience was younger than at the Met, so too were the singers, all of whom seemed to be in their mid-20s. Fausto Miro and Junhan Choi were wonderful as Rodolfo and Marcello. Abigail Krawczynska was appropriately bewitching as Musetta. Sarah Cooper sang Mimi beautifully.

La Bohème contains a scene that ties right into today’s news. The young attractive Musetta hangs around the elderly rich Alcindoro and extracts cash from him. This role, along with that of Benoit, the confused landlord, was acted and sung well by Matthew Stansfield, but he was not convincingly elderly when viewed up close. That’s one limitation of “opera in the small”: the performers need to match the roles more closely than when the average audience member is 200′ away.

One suburban couple: “We would go to opera every night if it were like this.”

Readers: What do you think? In an age where everything can be captured and streamed, as with the excellent Metropolitan Opera performances in movie theaters, would it make sense to say that live opera should be done in small halls? This might be the only way to keep the art form vibrant for the next generation.

Social Justice Warriors do not dispense Social Justice?

The Los Angeles Times is committed to the righteous path of social justice. From “Hillary Clinton would make a sober, smart and pragmatic president. Donald Trump would be a catastrophe.” (by the full Editorial Board):

The election of Hillary Clinton as the first female president of the United States would surely be as exhilarating as it is long overdue, a watershed moment in American history after centuries of discrimination against women.

From April 14, 2018, “A welcome assault on the gender wage gap” (by the full Editorial Board):

Year after year, study after study has come to the same depressing conclusion: Women are paid less than men in most every occupation, from accounting to teaching to sales to nursing. In the 55 years since the federal Equal Pay Act was passed, the gap has shrunk a bit, but it’s still far too wide. … it is unfair and dispiriting … prehistoric attitudes about the value of women’s work persist and are reflected in their collective pay.

These gender equity warriors are now leaving the newsroom for the courtroom, but not on the side that you might expect… “LA Times Union Preparing Class-Action Lawsuit Over ‘Illegal Pay Disparities’: Last week, an analysis of the newsroom’s pay structure revealed wide discrepancies along racial and gender lines.” (Huffington Post)

Readers: Explain this apparent paradox!

Happy Earth Day and Happy 20th Anniversary to Scorecard.org

Almost exactly 20 years ago I was part of a team that launched scorecard.org, a web site that enables consumers to check out pollution in their neighborhoods. (See also this chapter of a tutorial book on Web development that describes it.)

The site is still running, remarkably, a tribute to the persistence of Bill Pease, the Big Idea person behind it. (I take credit for “Why don’t we just have people type in their ZIP code as the primary interface?”)

So Happy Earth Day to everyone and, if celebrating, try not to drink too much Toluene.

Interesting analysis of US home prices in the 1950s and now

“Why buying a house today is so much harder than in 1950” (Curbed) has some interesting numbers:

To understand just how unaffordable owning a home can be in American cities today, look at the case of a teacher in San Francisco seeking his or her first house.

Educators in the City by the Bay earn a median salary of $72,340. But, according to a new Trulia report, they can afford less than one percent of the homes currently on the market.

Despite making roughly $18,000 more than their peers in other states, many California teachers—like legions of other public servants, middle-class workers, and medical staff—need to resign themselves to finding roommates or enduring lengthy commutes. Some school districts, facing a brain drain due to rising real estate prices, are even developing affordable teacher housing so they can retain talent.

This housing math is brutal. With the average cost of a home in San Francisco hovering at $1.61 million, a typical 30-year mortgage—with a 20 percent down payment at today’s 4.55 percent interest rate—would require a monthly payment of $7,900 (more than double the $3,333 median monthly rent for a one-bedroom apartment last year).

Over the course of a year, that’s $94,800 in mortgage payments alone, clearly impossible on the aforementioned single teacher’s salary, even if you somehow put away enough for a down payment (that would be $322,000, if you’re aiming for 20 percent).

The figures become more frustrating when you compare them with the housing situation a previous generation faced in the late ’50s. The path an average Bay Area teacher might have taken to buy a home in the middle of the 20th century was, per data points and rough approximations, much smoother.

According to a rough calculation using federal data, the average teacher’s salary in 1959 in the Pacific region was more than $5,200 annually (just shy of the national average of $5,306). At that time, the average home in California cost $12,788. At the then-standard 5.7 percent interest rate, the mortgage would cost $59 a month, with a $2,557 down payment. If your monthly pay was $433 before taxes, $59 a month wasn’t just doable, it was also within the widely accepted definition of sustainable, defined as paying a third of your monthly income for housing. Adjusted for today’s dollars, that’s a $109,419 home paid for with a salary of $44,493.

I’m not sure that the author’s explanation of why houses are expensive today is right, but I think at least he is good at explaining that houses are expensive. (My personal view is that the U.S. is crazy bad at urban planning so there are only a few nice places to live and, with the population having quadrupled since the most recent batch of “nice places” were built (circa 1900), that puts a lot of pressure on prices.)

Readers: What do you think of this author’s arithmetic and, more importantly, his grand explanation?
