2008 Goes Out With A Bang, Crash, and A Boom

2008-12-31 John Winkelman

So there I was, driving Rick home from tai chi practice. We were heading east on Logan, at the Madison Ave intersection, when I noticed the stop sign. I hit the brakes, but on the fresh-fallen snow even ABS gave me no love. At about the middle of the intersection I saw “GMC” fast approaching my side window, so I let off the brakes and gunned the engine.

Apparently, I was half a second too slow.

The Escalade hit this side.

The Escalade hit my car about even with the driver’s side rear wheel, which spun the back end of my car around, up onto a curb, and into a telephone pole. The pole made contact just behind the passenger side rear wheel, and spun us back the other way and into a snowbank.

A telephone pole and a curb hit this side

We sat there for a second, making sure all of our parts were in the correct places, then jumped out and ran over to the SUV to make sure everyone was okay. Other than a smashed grill, there was not a mark on it. According to the tire tracks, the Escalade didn’t even slow down appreciably when it swatted my car out of the way.

Fortunately, no-one was hurt in either vehicle.

That was all last night about 9:30. I just got back from Wealthy Body Shop, getting some personal things out of the car. Seeing it in the daylight gave me a serious case of the shakes. The specific damage is not as bad as seeing that the car is no longer symmetrical, left to right. The whole thing is…warped.

my car is no longer bilaterally symmetrical

This is the first accident I have been in where I was at fault. It sucks.

I Think I Figured It Out

2008-12-01 John Winkelman

Back in February I posted a quote from Neal Stephenson’s book Interface, wherein he suggests we have, politics-wise, come through the ages of ideas, character, and charisma, and were now in the age of scrutiny. When Mr. Stephenson was at his local book signing earlier this autumn, I asked him what he thought the next “age” might be. He declined to give a specific answer, although he pointed out that people seem to be more attracted to simple-or simplified-answers as the world grows more complex.

I have been giving this issue a lot of thought, and I think I have an answer for what the new age is: Perception.

The age of scrutiny came about before the explosion of the internet, and blogging, and YouTube, and the instant transmission of information from the insect-eyed crowds at every public gathering. The age of scrutiny has become buried under an influx of signals so vast it is indistinguishable from random noise. Now we are caught in the flux between conflicting viewpoints, and trying to tease un-distorted images from a kaleidoscope as big as the world. An event barely has a chance to occur before ten thousand sources provide spin and commentary, and soon the most pressing question is “Did anything actually happen in the first place?” If there is something verifiable, should it be thought of as good or bad? Patriotic or traitorous? Profitable or unprofitable? The uncountable eyes in the hive of perception each provide a unique view, but in aggregate that which is most seen becomes a form of consensual reality.

We have always lived in an age of perception to some degree, but during the age of scrutiny people – briefly – were able to use technology to sift through any available information coming in. But now our ability to produce information has so far outstripped our ability to make sense of it that we are back where we were in the late 1960s. And we will probably stay here until the next paradigm shift in pattern recognition.

A Murder in Heritage Hill

Crows

This (and other you can see by clicking the photo) is a small part of a large flock of crows which gathered near the corner of Union and Lyon late this afternoon. This is the first time I have seen crows in this neighborhood.

Procedurally Generated Map With Shading

2008-11-02 John Winkelman

Procedurally-generated map

Click here to load the map. Once it launches, click the movie to activate it, then use the arrow keys to move around. Clicking “reset” will create a new map.

This is a quick update to the tile game experiments of days past. I worked up a better color palette, and figured out a way to include shading to provide a better sense of depth and scale.

Perlin Ants In Color

Perlin ants in color

Click here to launch the ants.

Click the left button to reset the terrain which the ants follow.
Click the right button to show and hide the terrain.

1800 ants in a full-color version of yesterday’s experiment. Instead of looking for dark/light pixels, the ants look at the different color channels of the pixel they land on – red, green and blue. Then the ants follow the same pattern as yesterday – dark pixels turn left, light pixels turn right – based on the intensity of the target color.

Yup. I like how this one turned out, too.

Perlin Ants with visible terrain

Click here to launch the ants.

Click the left square to generate a new terrain map.
Click the right square to show and hide the terrain map.

This is kind of a mash-up between bits and pieces of some previous experiments – the terrain from the tile-based game, and the ants from the Langton’s Ants experiments.

Basically, what is happening here is this: A thousand “ants” are created and placed in random locations on the screen, facing in random directions. Each turn, each ant moves forward one pixel. If the color of the new pixel is lighter than the previous pixel, it turns a bit widdershins. If the new pixel is darker, it turns a bit clockwise.

The ants end up tracing something like contour lines, and seem to be “attracted” to sections where the color of the terrain varies significantly over a small area.

I threw in a bit of a blur to make things more interesting visually.

Enjoy!
