A-Class Catamaran Video: 2012 German Championship

Last month I mentioned a beautiful video of the 2011 German Championship that emphasized storms and stark scenery.

Here is a video of the 2012 Championship that is much more upbeat and celebratory. The weather certainly sets the tone.

This version has some aerial views that can be grabbed to study. It is always useful to review a start line.

And here is the natural separation of the fleet, hinting at wind disturbance and shadow for each boat.

Snow on the Mountain in Kansas: Konza Prairie

It’s been a while since I mentioned the Konza and security so I thought maybe it’s time for an update. Often when Kansas comes up in conversation I hear either one or two responses from Americans:

  • The Land of Wizard of Oz! Where’s Toto?
  • It’s so flat and boring! Right? One time, I drove cross-country and Kansas seemed to take forever…

Yes and yes, but no.

First, the political and historical relevance of the Wizard of Oz and its secret story are definitely related to Kansas. I mentioned it in 2006 and noticed a lot more interest in it after the financial crisis of 2008.

US political historian Quentin Taylor, who supports [Littlefield’s 1964] interpretation, says: “There are too many instances of parallels with the political events of the time.

“The Tin Woodman represents the industrial worker, the Scarecrow is the farmer and the Cowardly Lion is William Jennings Bryan.”

[…]

The Wicked Witch of the West is associated with a variety of controversial personalities, chief among them the industrialist Mark Hanna, campaign manager to President William McKinley.

In this scenario, the yellow brick road symbolises the gold standard, the Emerald City becomes Washington DC and the Great Wizard characterises the president – and he is exposed as being less than truthful.

The little dog doesn’t really have any significance (despite some suggesting Toto represents a teetotaler) once characters are framed in 19th Century deflation and depression, with a struggle between populists and industrialists (e.g. the 99% and 1%). That is why no one knows where Toto is.

Second, I have not yet written very much here about my impression of the terrain. So here’s a good example of why flat may not really be flat. This is a photo I took a long time ago. Notice what it does to your focus. The Konza landscape was formed from glacial runoff into giant valleys. Barely hidden beneath the tallgrass are rocks and boulders.

At first glance it may seem to be an endless green space or a flat top. The trained eye soon realizes the open space of a tallgrass prairie belies billions of interesting data points. You might not believe it at first but snow-on-the-mountain is right there, in front of you.

Hills are formed from an inverse effect. What you see through a little window at 70 mph could be a trick on your eyes; easy to focus only on the flat top with some blur below. But take a back road that tries to conquer the elevation change or slow down and let your eyes soak up the view. When you stop you will find an incredible diversity of life at the micro level.

It’s similar to the ocean. You can stare accross the sheer expanse of it through a window and see the emptyness. Or you can ride a wave and slow down to observe life below peak elevation. If you let the data in, you might be amazed.

U.S. Navy Supercomputers Predict Weather Threats

Calm waters mean greater chance of attack, as I mentioned recently, so weather forecasts can give a major advantage. CNet reports on the latest technology:

[The Fleet Numerical Meteorology & Oceanography Center] benefits from its immediate proximity to weather and supercomputing experts at the Naval Research Laboratory, the National Weather Service, and the Naval Postgraduate School, all of which are in Monterey. That allows Fleet Numerical’s team of just 13 officers, 13 enlisted, and 128 civilians to do a job that the National Weather Service’s own forecasting center needs at least three times the resources to do, while the U.S. Air Force’s needs twice as much, Sauer explained.

[…]

Fleet Numerical’s most powerful supercomputer is a Dell Linux cluster system known as A2 Emerald with 27.3 peak teraflops. But that runs the center’s unclassified global modeling, which brings in giant amounts of data from countries all around the world. Its classified and Top Secret computers are smaller, and are geared towards much finer resolution regional and local modeling.

This Day in History: Escape From Alcatraz

It was fifty-years ago tonight, June 11, 1962, when convicted bank robbers Frank Lee Morris, Clarence Anglin and John Anglin disappeared from Alcatraz. They were never found.

It took them a year to create the escape route, disguise it and create the necessary tools. Soap and toilet-paper turned into decoys, air ducts became doorways, and rubber raincoats and plastic bags made a raft. On the night of the escape a ventilation shaft behind air ducts to their cells gave them a route to the roof. From there they climbed down a chimney on the outside of the building and then paddled their raft towards Marin. Mythbusters recreated the scene and tested the raft’s seaworthiness.

Morris is credited with devising the plan during his first year at the deteriorating facility. He had been sent to Alcatraz in 1960 on a sentence that would have ended in 1974. Instead, he escaped and it was closed by 1963.
