I was the leadoff speaker at the American Association of Individual Investors conference in Las Vegas. I enjoyed meeting participants, disproportionately older folk asking questions about how to financially assist their adult children and grandchildren. While there, I took some pics….
…So says the White House Council of Economic Advisors, anyway.
Nonlinear functional forms make Trump look even better in most cases
— CEA (@WhiteHouseCEA) September 10, 2018
I’d wanted to learn how to do K-means image compression in R. So I decided to fact-check CEA’s claim by seeing what President Trump would look like if I compressed his image. Total time from googling R code to posted image: 15 minutes. Props to this guy for the clear code.
On the whole, I would have to say that CEA’s claim checks out…
CEA: "Nonlinear functional forms make Trump look even better in most cases."
Politifact evaluation: True. (kmeans k=2, k=3).
(Not a knock on the President's appearance. Of course he is more handsome than I am. Just a fun opportunity to learn R-based image compression.) pic.twitter.com/DOEP4b3CLl

…And she did some walking around…
On a poorly-planned trip, I got fewer good pics than last year, but a few decent ones. Mainly, the trip demonstrated the value of high-quality equipment. My full-frame camera with a 300mm lens got much better pics than my new super-zoom Nikon P900. The P900 got a few cool pictures of parachutists from miles away, but the soft lens, camera jitter, and related challenges made it hard to do action shots at high zoom.
(Me from two years ago)
A four-year-old with her toy basket and cute yellow boots plays with her father in the sand. She has no way to understand–not that the rest of us really do, either that the spot on which she is playing was once a killing field, Juno Beach, where so many brave Canadian troops were subject to withering German fire on the morning of June 6, 1944.
Our tour bus from Paris hit the usual sites. Memorials to Allied soldiers pepper the area. We saw no memorials to their German adversaries, who fought all too bravely and well for an unspeakable cause. I cannot honor these men. Yet they, too, left much behind.
Like many of my contemporaries, I was a childhood World War II buff. I’ve probably read a hundred books on World War II since I was a child. I learned world geography from the battle maps of American Heritage accounts of Midway, Stalingrad, and the Ardennes. So I was intimately familiar with our guide’s account of the logistical feats and planning missteps in Operation Overlord’s first day.
I knew of the bombing runs missed, the amphibious vehicles than had sunk. I knew about the currents and tides led many of the invaders to arrive a fatal thirty minutes late or to land a fateful few hundred-yards from their intended site. The greatest and most consequential victory of American arms since 1865 was, at ground level, bloody chaos, replete with tragic mistakes and accidents that led thousands of men to die.
I knew about the American Rangers who rappelled the steep face of Pointe du Hoc, while German troops on the ridge above slashed their climbing ropes and rained down grenades. I did not, until Saturday, know what that rock face looked like from above.
We held a University of Chicago event tonight for the GPHAP program. Some pictures were taken from the fifth floor of our Gleacher Center.
Bad news: I left the camera on ISO 2000 for a bright morning in the sunshine. Good news: Full-frame camera recovered some decent shots.
Sometimes, you just have to walk up to someone and ask if you can take his picture.
