I got a text message yesterday from one of my co-teachers in an upcoming pilot ground school class. She wasn’t in my contacts, but iOS found her phone number in an email and put a “Maybe: Tina Prabha Srivastava” up at the top of the Messages page. I clicked on the “i” button and tried to “Add New Contact”. At that point, however, the inferred name had been dropped and I was forced to retype everything (except the phone number) by hand.

“Mel Gibson’s ex sued for $108K over child support fight” (Page Six) provides an interesting window into just how much Americans spend on transaction costs in family court:

Court documents obtained by The Blast reveal the forensic accounting firm that Grigorieva, 47, hired to investigate baby daddy Mel Gibson’s finances in her child support fight, is suing the singer for $108,000 for unpaid fees.

Grigorieva hired White, Zuckerman, Warsavsky, Luna & Hunt following her 2015 bankruptcy filing, and the company claims they aided Grigorieva in getting her child support payments increased to $22,500 per month for daughter Lucia.

In their filing, the firm noted that Gibson, 61, paid the bulk of their charges with the exception of the unpaid balance of $108,887.24.

I.e., the accounting fees were in excess of $218,000 for this child support modification action (Gibson paid at least 50 percent if it was “the bulk of the charges”). Just imagine the legal fees!

Note that, despite the fees, litigation should have been a rational strategy for the plaintiff. Her daughter is now yielding tax-free revenue of $270,000 per year. That’s nearly $5 million over the 18 years during which a child can yield a profit under California family law. Legal and expert fees might be pretty close to the $5 million number, but her defendant will pay most of them.

[The defendant in this case is famous, which is why the lawsuit is in the news, but this scale of fees is consistent with what is spent when ordinary high-income Americans are sued.]

Young readers: Remember that going to accounting school doesn’t mean being stuck filing 1040 returns!

Time to plan summer travel! Here’s an idea for pilots with kids: a 48-state tour of the U.S. in a four-seat airplane, hitting a bunch of historical sites, especially pre-Columbian, with at least a touch-and-go in every state. The tour should take roughly three weeks with about 50 hours of flight time in a Cirrus SR20 and cost about $5,000 for fuel and engine/prop reserves.

See

• the route on Skyvector (note that coming down the spine of the Appalachians enables a lot of Eastern states to be knocked out without too much flying; staying on the east side of the West Coast states also saves quite a bit of flying time, though there is a lot of wilderness)
• an annotated navlog with some information about what to do and see at each stop

A Cirrus SR22 with air conditioning would certainly be a more comfortable choice for this journey, but it could also be done in an even more basic plane, such as a Cessna 172.

Aviation rules:

• Pick airports such that we can land within 60 percent of available runway (i.e., FAR 121 airline safety margins)
• Avoid IMC/IFR since a big reason for this trip is to understand the landscape rather than be inside a cloud, despite the high level of avionics and autopilot capability of the Cirrus.
• No night flying in the mountains.
• No IMC/IFR flying in the mountains.
• Wait out any afternoon thunderstorms; fly the next morning.
• Cross big mountain ranges only when winds aloft are 30 knots or less, ideally first thing in the morning.
• No over-water operations (go around Great Lakes); saves having to carry a raft

Prep:

• Update Cirrus with ADS-B transponder
• Upgrade Jepp and Garmin subscriptions to cover all of North America
• Get oil changed by East Coast Aero Club (good for 50 hours so plane will be just ready for another change upon return)
• Send oxygen system out for recertification
• Send in PLB for fresh battery

Best time of year? If the kids are substantially ahead of grade level, take them out of school around June 1 so as to avoid (a) peak summer school vacation crowds, and (b) peak summer temperatures that will compromise aircraft performance. For home-schooled kids, maybe start this trip on April 15?

Readers: Thoughts on the overall idea or route?

… and then wasting the rest.

Vanity Fair has published an except from Brotopia that has my Facebook friends talking.

[The excerpt does not take the Wall Street position that “there are two sides to every trade.” There are, instead, victims and victimizers. This lead to a Facebook comment regarding the purported victims: “they thought that they were going to Bible study with some good Christian friends”]

Traveling by car in Manhattan has slowed down 27 percent in the last 5 years, from a slow running pace of 6.5 mph on average to a fast walking pace of 4.7 mph (nytimes).

“The Most Expensive Mile of Subway Track on Earth” (nytimes) says the same thing as New Yorker magazine (the U.S. spends 5-6X what it costs other developed countries to build infrastructure), but supplies details on the no-show jobs, the $400/hour for union construction workers, etc.

As the U.S. population grows (due almost exclusively to immigration) and our successful cities reach Chinese-style population densities, I wonder if it is time to abandon the idea of travel by road or rail. Instead of trying to relearn how to build major infrastructure projects, why not arrange cities into walkable sub-cities in which the primary mode of transportation is via foot? To speed up travel-by-foot time, New York could build catwalks about 15′ above the streets. This is a pretty simple project that should be within an American local government’s capability and it would speed up travel times tremendously (no waiting for lights; no fighting for space on sidewalks that have become crowded).

Details: compensate building owners for the compromised view from the second floor windows by reducing the property tax rate on those floors.

Readers: Thoughts?

The forecast for our local airport (Boston suburbs) is a high of 4 degrees F on Saturday with a low of -12.

Tomorrow will be toasty warm by comparison with a high of 29. Time to celebrate? I just got this email from the airport operations folks:

Tomorrow, Thursday 1/4, we are expecting 10-15” of snow with blizzard conditions, followed by high winds gusting over 50mph and frigid wind chills down to -25F through Saturday 1/6.

To better assist you, we ask you to advise us of any planned flight operations on Thursday 1/4 or Friday 1/5.

(The airport almost never officially closes, but sometimes a runway will be closed for snow-plowing and also sometimes runways are in marginal condition, e.g., covered with an inch or two of snow.)

From the school on Monday:

As you know we are experiencing extreme cold temperatures with dangerous wind chills. This is a reminder to ensure that your children are properly dressed for the conditions as they prepare to return to school tomorrow. … Our principals, including the preschool coordinator, will be working with faculty to ensure the safety of children throughout the day. As always, you should make the decisions that are best for your family regarding transportation to school and school attendance under severe weather conditions. [emphasis added]

(As it happened, the school building, slated for a $100 million identically sized replacement, was so thoroughly heated that students and teachers ended up opening windows to obtain a comfortable T-shirt temperature in the classroom.)

One of our local public radio stations (see this previous post on the finances), WBUR, ran an article (“2 Firms To Investigate Allegations Against Tom Ashbrook”) about unhappy times among staff members of the On Point show. I.e., the news organization is reporting on itself. This makes sense because WBUR is packed full of journalism professionals who are great as investigations, right?

But then it seems that they are going to spend listener donations on hiring a $1,200/hour law firm, Holland & Knight, to figure out who had sex (or wanted to have sex? or talked about sex?) with whom. They’re hiring a separate contractor to look at “allegations of name-calling” (why not give the cash to local 3rd graders? That’s where I would go to find expertise in this area!).

I could understand WBUR not wanting to write about its own internal dispute and also leaving any investigation to outsiders. But if they are going to investigate this sufficiently to write the article, why can’t they finish the investigation internally? Why not simply have the reporter who wrote the above-cited article continue interviewing people and deliver a full account to management?

Over the past 10-20 years I have noticed an increasing percentage of young people seeking to spend their careers in non-profit enterprises, e.g., universities or public radio stations. Americans also now seek government jobs as avidly as 15th century Chinese did. Now that the tax code has been revised to make starting and operating a business more financially rewarding, I wonder if 2018 will be a year in which more Americans become interested in the (formerly?) dwindling for-profit sector of the economy?

Readers: What do you think? If for-profit corporations get to keep more of their profits, will that enable them to compete more effectively with non-profits for the next generation of workers?

Happy New Year!

How about a resolution to learn something new in 2018?

Under the time-honored medical school principle of “See One, Do One, Teach One,” I am preparing to help medical students use the R programming language. This post is to share what I’ve learned about learning R.

Set up your PC: download R and then download RStudio.

Advice from a friend who teaches machine learning at Harvard… “For a traditional procedural programmer”: read R Cookbook (O’Reilly); “For someone with low-level or Lisp knowledge”: read Advanced R (CRC).

[Somewhat tangentially, he recommended An Introduction to Statistical Learning, with Applications in R (James, et al; Springer), or The Elements of Statistical Learning (Springer), which can be used to awe friends with all of the equations and graphs.]

If you’d rather watch lectures and take short quizzes, start with the free edX course Data Science: R Basics. The next step on edX is Statistics and R, part of a seven-course series.

Separately, I’m not sure that I love R so far. “Like APL without the special keyboard” seems like a fair description. All kinds of magic happen with just a character or two and I worry that code won’t be readable, maybe even by the original author!
