mannylopezon Show HN: Tiny Moon – Swift library to calculate the moon phase

Thank you! I was a technical writer before learning how to program, so it's important for me to write well-documented and well-tested code.

Doing so also allowed me to completely remove and replace my first attempt at implementing the moon phase algorithm when it turned out to be not-accurate enough (the values were off by about 4 hours).

Yes, pretty much every good library I came across referenced Meeus' Astronomical Algorithms [0] book and formulas. Those were a bit dense for me to fully parse, but Dr. Louis Strous` page [1] on finding the position of the moon helped simplify it for me (although that implementation is less accurate, I think).

The algorithm in Moontool for Windows [2], which Tiny Moon is based off of, is based off of Meeus' algorithm.

Good news! According to Swift Package Index [0], Tiny Moon is already compatible with Linux environments.

mannylopezon Music for Programming

My go to music is the band Kiasmos. They're an Icelandic duo that plays atmospheric/minimal techno music. They're on hiatus now, so if anyone has any music that's like this, I'd love to hear your recommendation.

mannylopezon The Sweden Solar System

Peoria, Illinois has one too and claims the "world's most complete large-scale model of the Solar System. The scale factor is 99,000,000:1, covering 6,000 square miles of Central Illinois."[0] and you can "become a part of the world's most complete large scale model of the Solar System by purchasing an Unnamed Comet Plaque in the Peoria Riverfront Museum Store. Unnamed comet plaques are located on all seven continents, stretching as far north as Barrow, Alaska, and as far south as South Pole Station, Antarctica."[1]

I hate going to drive.google.com to create a new doc and was about to build a shortcut for myself, but it turns out that Chrome already has these built in!
