Gimme Friction, Baby!

Wednesday, August 8th, 2007

This game is amazing and addictive and totally mind-bogglingly difficult.

I love it! Got a top score of 8 so far, but I think the learning curve on this one is an exponential function of both patience and free time.

  

Stretch Run

A quick post about the remaining schedules for the Red Sox and Yankees. I listed out all the series that the two teams have remaining for the year. Then I canceled out matchups that the two teams had in common, while ignoring home field advantage. For example the Sox have two series with Baltimore remaining and so do the Yanks, so those were canceled out. The remaining series that each team has are:

Boston: White Sox (Winning Percentage = .464), 2 vs. D-Rays (.375), Oakland (.474), Minnesota (.509)

New York: Cleveland (Winning Percentage = .566), 2 vs. Detroit (.563), Seattle (.555), Kansas City (.441)
The teams also play two three game series against each other, one in Boston and one in New York. The bottom line: the Sox have a much easier schedule going forward than the Yankees do.

POTW #1: Squirrel by the Sphynx

Squirrel

Nathaniel suggested I post a photo of the week (POTW) on the blog. Here is the first, a squirrel in a tree near the sphynx. What do you think? (click image for a larger version)

technical specs:
shutter: 1/160, aperture: f/3.5, focal length: 72mm (432 mm in 35mm equivalency) distance: about 4 meters

Additional notes: In a high contrast image taken with a digital camera, it can be difficult to avoid chromatic aberration (CA), which often appears as purple fringing at the boundaries between light and dark in the image. This is caused by a few things:
1) the red and blue pixels on the CCD are more sensitive to IR than the green ones,
2) IR is focused differently than visible light by the lens
3) I think the interpolation from the RGB images probably has a hand in it too.

This image showed some CA at the lower edge of the branch and around the leaf stem in the bottom of the frame. I removed the purple fringes by desaturating magenta in the GIMP. See the before and after below (this image is also clickable to enlarge):

Note that the “corrected” image has also had some adjustments to levels and curves.
