You can’t go home again, unless you are just in the nick of time

1999: Andrea and I (finally) get married at Sunset Point, a beautiful circle of palm trees atop a grassy knoll overlooking the Seven Seas Lagoon and, in the distance, the Magic Kingdom, at the Polynesian Resort in Walt Disney World.

The years that follow: we start a family, hoping always to return to that magical spot.

2013: We (finally) return to WDW and Sunset Point, this time with the fruits of our union.

A few months later (as I learned just this morning via a Google Follow Your World update), Sunset Point looked like this:

Gone forever, to make way for the construction of new villas over the lagoon, and as part of a general revamp of the resort, probably in anticipation of Disney’s upcoming Polynesian-themed film Moana.

Walt Disney himself endorsed the continual reimagining of his parks, and no doubt the Polynesian will be as magical after these changes as it was before. But that circle of palm trees was my one favorite place in the entire world. Goodbye Sunset Point! Thank heavens we made it back to you just in time.

Exciting coincidence!

California’s license-plate scheme is


We can consider this as a number written with one base-10 digit followed by three base-26 digits (where A is 0, B is 1, C is 2, etc.) followed by three more base-10 digits. It’s easy to convert such a sequence to a pure base-10 number. For instance, 0AAA000 is 0. 0AAA001 is 1. 0AAA002 is 2. And so on up through 0AAA999, which is 999, and then to 0AAB000, which is 1,000. 0AAC000 is 2,000. 0AAZ000 is 25,000. 0AAZ999 is 25,999, and 0ABA000 is 26,000. And so on.

Here is a short Python function that does the conversion:

def plate_to_number(sequence):
  result = 0
  for character in sequence:
    if character.isdigit():
      result = result * 10 + int(character)
    elif character.isalpha():
      character = character.lower()
      result = result * 26 + (ord(character) - ord('a'))
  return result

My first license plate on moving to California in 1992 was 2ZZZ923, whose number value is 52,727,923. Now here’s the exciting coincidence: the number value of my current license plate, from 2007, is almost exactly double that (to within an error of 0.014%)!

Well, it’s exciting to nerds.
