Even in the TRON future they still have the problem that "ps aux | grep" includes the grep itself.

screenshot from TRON Ares where the villain is trying to restart something and runs "ps aux | grep -i SHV" and then sudo systemctl restart on the pid. the grep list includes their own process.

Here's the cropped video of the flashing light on the crane; the first few seconds are real time and then the video slows to 240fps.

The crane across the river from my house has been bothering me for the past year with a flickering light, so I did what any reasonable person would do: shoot a 240fps video of it to see if it was encoding data. The flashes from different samples seem to align very well, so maybe pulse width modulated?

snowy bridge across a river at night with a work crane above a theater two bar graphs of the intensity of the light on the crane, plotted versus time and aligned so that maybe there is a binary pattern encoded in the two of them.

Controversial opinion: navigation is much easier with decimal math instead of minutes and seconds. I make far fewer mistakes with base ten than sixty, plus 0.01 is slightly smaller than 1/60. And besides 1' equals 1 nautical mile only at the equator so it's not really very useful on the rest of the planet.

Intercept success! The Lines of Positions from two Sun sights converge on the actual location (within a few nautical miles at this scale)

Fixed the LHA computation to use the DR longitude instead of the actual longitude and now the lines of position converge very close to the actual location!

lots of colored lines that cross at a point with a small circle drawn nearby

That's better, although now they all converge at the actual latitude but the dead reckoning longitude position.

lots of colorful lines that cross at a central point, rather than the actual point (represented by a small circle to the left)

Something is wrong with my math. The LOP aren't lining up correctly.

Math is hard. Let's go sailing.

Sight reduction tables, plotting worksheet, normal slide rule and a custom one for degree math.
