🌘 Hengefinder：尋找太陽與街道對齊的時刻
➤ 從幾何糾偏到精準搜尋：如何用程式碼鎖定懸日時刻
✤ https://victoriaritvo.com/blog/hengefinder/
本文分享了開發者如何打造「Hengefinder」工具的歷程。這項計畫的核心在於計算曼哈頓懸日（Manhattanhenge）這類天文景觀出現的時間。作者透過解析街道方位角（Bearing）與太陽方位角（Azimuth），克服了地球曲率帶來的幾何誤差，並利用二分搜尋法精準鎖定太陽觸及地平線的時刻。這不僅是一個技術專案，更是一次將地理直覺與球面三角幾何實踐結合的探索。
+ 這篇文章展示瞭如何將枯燥的球面幾何應用在實際生活，特別是處理經緯度誤差的那段說明非常清晰，解決了我一直以來的盲點。
+ 使用二分搜尋法來尋找太陽高度角的臨界值，這個思路非常巧妙，比單純的暴力遍歷高效且優雅得多。

@Goffi thanks for the tip! Sure i'm gonna try again... and contribute with some feedback.
Hopefully it may very well guiding our classrooms next course.

The most common place we use super() in #Python? __init__:

class Child(Parent):
def __init__(self, a, b, c):
super().__init__(a, b) # Parent sets a + b
self.c = c # Child sets c

c = Child(10, 20, 30)
print(vars(c)) # {'a':10, 'b':20, 'c':30}

#Python ist bei Ausgaben auf stdout schneller als #rust ? Python flushed seltener: https://blog.strangerthanusual.de/blogposts/to_flush_or_not_to_flush
To flush() or not to flush()

Bei I/O sollte man vorsichtig sein, wie oft man flushed. Insbesondere, wenn die Programmiersprache eigene Ideen hat, wann geflushed werden soll.
