The Next Episode of Billions?


"German police arrested a man on Friday suspected of detonating three bombs that targeted the Borussia Dortmund soccer team bus in the hope of sending the club’s shares plummeting and making a profit on an investment, prosecutors said.

In a statement, the federal chief prosecutor said the 28-year old man, a dual German and Russian national identified as Sergei V., had bought options on Borussia Dortmund’s stock before the attack.
The team bus was heading to the club’s stadium for a Champions League match against AS Monaco on April 11 when the explosions went off, wounding Spanish defender Marc Bartra and delaying the match by a day.

Prosecutors last week expressed doubts about the authenticity of three letters left at the site of the attack that suggested that Islamist militants had carried it out.

The prosecutor’s office said the suspect had bought 15,000 put options, or contracts giving him the right to sell Borussia Dortmund’s shares at a pre-determined price, on the day of the attack, using a consumer loan he had signed a week earlier."

Facebook Looks at AR


"Facebook hopes to take further advantage of developing technologies such as Simultaneous Localisation and Mapping (SLAM) which allows the camera to plot out where an object is in the real world so AR can seems to be placed accurately in the ‘real world’. Additionally, Facebook are working on technology that allows the conversion 2D stills mages into 3D representations that can be modified with AR. The object recognition that will be introduced to the app means that the camera can ‘recognise’ the size, depth and location of the object so the object can be manipulated within the AR space."

Climate Change Population Migration

From Nature Climate Change:

"Many sea-level rise (SLR) assessments focus on populations presently inhabiting vulnerable coastal communities1, 2, 3, but to date no studies have attempted to model the destinations of these potentially displaced persons. With millions of potential future migrants in heavily populated coastal communities, SLR scholarship focusing solely on coastal communities characterizes SLR as primarily a coastal issue, obscuring the potential impacts in landlocked communities created by SLR-induced displacement. Here I address this issue by merging projected populations at risk of SLR1 with migration systems simulations to project future destinations of SLR migrants in the United States. I find that unmitigated SLR is expected to reshape the US population distribution, potentially stressing landlocked areas unprepared to accommodate this wave of coastal migrants—even after accounting for potential adaptation. These results provide the first glimpse of how climate change will reshape future population distributions and establish a new foundation for modelling potential migration destinations from climate stressors in an era of global environmental change."

A Paragraph to Ponder

From the Washington Post:

"Demand for flights to the United States has fallen in nearly every country since January, ­according to Hopper, a travel-booking app that analyzes more than 10 billion daily airfare price quotes to derive its data. Searches for U.S. flights from China and Iraq have dropped 40 percent since Trump’s inauguration, while demand in Ireland and New Zealand is down about 35 percent. (One exception: Russia, where searches for flights to the United States have surged 60 percent since January.)"

Better Call Saul

From the New York Times:
"In an hour long news conference that touched on race, policing and airline manners, a lawyer for the passenger dragged off a United flight on Sunday listed his client’s injuries: a broken nose, a concussion, two knocked-out teeth and sinus problems that may require reconstructive surgery.
“For a long time, airlines, United in particular, have bullied us,” the lawyer, Thomas A. Demetrio, said Thursday in downtown Chicago.
“Are we going to just continue to be treated like cattle — bullied, rude treatment?” asked Mr. Demetrio, who placed the blame for his client’s injuries on a “culture of disrespect” at United Airlines and overly aggressive tactics from Chicago aviation police officers. He said a lawsuit was likely.
The video of Dr. David Dao, 69, of Kentucky, being bloodied as he was pulled off the flight in order to make room for four United employees has ignited conversation and outrage around the world. The three Chicago aviation police officers who removed Dr. Dao from the plane have been placed on administrative leave."

Thoughts on Speed Bumps

From Tyler Cowen:

"By its very design, a speed bump is a deliberate obstruction with maximum transparency as such. It is sending a message that the social goals of safety or neighborhood quiet are sufficiently important that it is worth slowing people’s progress when they travel. There are many regulations that try to make our lives safer, but most of them are hidden, with nontransparent costs, such as auto-safety regulations as applied through crash tests. A speed bump, in contrast, can work only if people notice it each time. So to the extent a society accepts speed bumps, it is visibly advertising the notion that limits to fast transportation — a symbol of progress — are acceptable in the name of safety and cozy locality."

Off to Texas Water 2017

A Paragraph to Ponder

From Arup Thoughts Column:

"The increasingly interconnectedness of today’s infrastructure networks poses additional risks to be overcome. In the event that a freak storm damages a key telecoms facility, the danger might be that the ensuing loss of connectivity creates cascading failures, such as suspending key systems at a local power plant or hospital. Hurricane Sandy in 2012 caused many such connected failures. It also damaged data centres relied on by media organisations like BuzzFeed and the Huffington Post. The issue of interconnected failures in vital aspects of our day-to-day infrastructure will require a ‘systems thinking’ response if climate change resilience is to be achieved."

The Importance of Engineering Resiliency this Century

From the New York Times:

"Prosperity will ultimately belong to cities and nations around the world that find ways to capitalize on strategies of resilience against the inevitable impact of climate change. Those cities will retool themselves for new technologies and global businesses whose employees, reflecting a growing worldwide generational shift, want to walk, ride bikes and take mass transit."

Rising Waters and the Costs of Inaction

From the New York Times by Michael Kimmelman and Josh Haner - Rising China Waters Imperil a World of Progress:

"That’s a trillion-dollar question, according to the World Bank, which projected the potential cost of damage to coastal cities worldwide from rising seas to be somewhere near that figure. It estimates that China is already losing 1.4 percent of its annual G.D.P. to climate change. Last spring, residents in Guangzhou woke again to flooded streets after a furious downpour swept across the delta and drowned entire neighborhoods of the city. Local news media, once more, said that there had been nothing like it in years. And as usual, Chinese social media sites buzzed with posts of people trapped in flooded cars. One man, named Pang, became an overnight celebrity for catching a fish with his umbrella, then going home and making soup with the head and tail. “It was fresh and tender,” he told The Guangzhou Daily."

Engineering Puzzle Solvers

"Two intelligent, honest students are sitting together at lunch one day when their math teacher hands them each a card. “Your cards each have an integer on them,” the teacher tells them. “The product of the two numbers is either 12, 15 or 18. The first to correctly guess the number on the other’s card wins.”
The first student looks at her card and says, “I don’t know what your number is.”
The second student looks at her card and says, “I don’t know what your number is, either.”
The first student then says, “Now I know your number.”
What number is on the loser’s card?"

The New Dynamics Shaping Engineering

From the current issue of the Economist:

"Parking spaces seem innocuous, just a couple of lines painted on asphalt. Multiplied and mismanaged, though, they can create traffic jams, worsen air pollution and force cities to sprawl. The cost and availability of parking affects people’s commuting habits more than the rapid buses and light-rail lines that cities are so keen to build (see article). Next to other worthy policies like congestion-charging and road-tolling, parking is also easy to change. The fast-growing metropolises of Africa and Asia, especially, need to get it right, before they repeat the West’s debilitating mistakes."

Civil Engineering for Shrinkage

Safer Cars Yet Higher Insurance Rates

From the WSJ:

"New cars loaded with high-tech crash-prevention gear are having a perverse effect on car-insurance costs: They are soaring.

Safety features such as autonomous braking and systems to prevent drivers from drifting out of their lanes are increasingly available on vehicles rolling off assembly lines. Auto companies and third-party researchers say these features help prevent crashes and are building blocks to self-driving cars. But progress comes with a price.

Enabling the safety tech are cameras, sensors, microprocessors and other hardware whose repair costs can be more than five times that of conventional parts. And the equipment is often located in bumpers, fenders and external mirrors—the very spots that tend to get hit in a crash. Insurance companies, unwilling to shoulder all the pain, are passing some of the cost off to buyers."

Leadership 101 - Don't Ignore the Obvious

Great observation from this blog post:
"For the last ten years, the low to mid-tier retailer Target has virtually ignored online shopping.  In fact, it continues to focus primarily on stores, very recently announcing a multi-billion dollar program to modernize 600 of its 1,800 locations and open more than 100 small format stores.  In recent years, they initiated an intensive online shopping effort, and are attempting to employ the Best Buy model of using stores as online distribution centers, but it’s late; Target is even behind Walmart.  Up until about 2 years ago, their bricks-and-mortar focus was serving them well.  More recently, things have gone downhill.  Specifically, Target stock is off 29% versus 12 months ago and is now below its stock price of 10 years ago.
There is no question that bricks-and-mortar retailers are suffering as fewer consumers are stepping foot into actual stores; more and more they are opting to shop online.  Department store sales in January fell 3.2% from a year earlier, continuing a downward trend for much of the past two years according to the U.S. Commerce Department.  Conversely, sales at non-store retailers, a category that includes online shopping and is dominated by, rose 12%.
Stepping back, the lesson is very clear.  Human beings are wired to sit back and enjoy any kind of success they achieve.  Success generates pride which can become a crippling mentality.  It often causes the individual to ignore the reality of what’s coming at them.  Target is simply the latest victim."

What I Learned From the Sunday Paper

My notes from the Dallas Morning News today - -

  • Economic growth is a demanding master - the more you have, the more you need.  Can Texas continue to draw large number of job seekers?
  • Dallas has a shortage of policemen and firefighters, and is having problems recruiting trainees because of the cloud over the pension fund.
  • Declining manufacturing employment and share of GDP are hurting the U.S. - without manufacturing you start to lose your position in the global value chain.  Finance, real estate, and the service sector have a daunting challenge to make up the difference.
  • What about hydrogen fuel cell powered cars that get their hydrogen from gasoline?
  • The median price of a house the U.S. is $234,900.  The median in Texas is $249,900.
  • Our sleep challenged society costs the U.S. economy $411 billion in lost productivity per year.
