🤯 Ah, the mystical #NaN, the not-a-number that still manages to baffle #JavaScript enthusiasts since forever. Let's watch as #developers ponder this enigmatic concept with the intensity of a cat chasing its own tail. Maybe someday they'll realize that multiplying an enigma by zero still ends up in 🤦♂️... NaN!

"Te catastrophic 2011 floods remain te most painful reminder: according to #WorldBank, they caused US$46.5bil in #economic losses, displaced 13 million people, & claimed approx'ly 800 lives. Fast forward to 2025, & te story is largely unchanged. Recent floods in #Nan (July), #ChiangMai (Aug) & #Phetchabun (Sept) highlight tt devastat'g #inundations continue..

Today in thinking-sideways news:
"NaN-Propagation: A Novel Method for Sparsity Detection in Black-Box Computational Functions", Peter Sharpe 2025
https://arxiv.org/abs/2507.23186
The abstract is already amazing.
"By systematically contaminating inputs with NaN and observing which outputs become NaN, the method reconstructs conservative sparsity patterns that eliminate a major source of false negatives."
"... advanced strategies such as NaN payload encoding via direct bit manipulation enable faster-than-linear time complexity, yielding speed improvements"

Не доверяйте groupby().first()
Привет, Хабр! В этой статье рассмотрим, почему groupby().first() в pandas — не такая уж безопасная и очевидная штука, как может показаться. Особенно когда нужно достать первую строку группы в точности, как она была в датафрейме — с NaN, с порядком, без сюрпризов. Но для начала рассмотрим отличия first от других подобных методов.

Balatro University Explains “naneinf” And How To Reach It
How do you reach an impossible score, so high that the counting system malfunctions and vomits up gibberish?

Is a #yaml document with a mapping that contains two #NaN keys valid? Are the keys duplicated? According to the spec scalars compare byte by byte and use the canonical representation. According to how people think about NaN values, this is not so obvious.
The spec uses the language: "Obviously, identical nodes are always considered equal." which reminds me that the word obviously is most likely never a good choice in a specification.
