Extending That XOR Trick to Billions of Rows

news.ycombinator.com Unknown 2025-08-25 03:15:41

Can we extend the XOR trick for finding one or two missing numbers in a list to finding thousands of missing IDs in a billion-row table? Yes, we can! This is possible using a data structure called an Invertible Bloom Filter (IBF) that compares two sets with space complexity based only on the size of the difference. Using a generalization of the XOR trick [1], all the values that are identical cancel out, so the size of this data structure depends only on the size of the difference. Most explan

‘Suzzanna: The Queen of Black Magic’ Is a Colorful Portrait of a Cult Horror Legend

Suzzanna: The Queen of Black Magic offers an excellent introduction to the Indonesian movie legend, but it’s a fun watch even if you’re already familiar with her work. Just about the only prerequisite for enjoyment is being a horror fan, because David Gregory’s documentary is packed with clips from Suzzanna’s gloriously over-the-top filmography, especially her much-loved early-’80s entries. “The Queen of Indonesian Horror,” as she came to be known, was born during World War II; she knew from an

Fanfic study challenges leading cultural evolution theory

arstechnica.com Unknown 2025-08-28 08:24:42

It's widely accepted conventional wisdom that when it comes to creative works—TV shows, films, music, books—consumers crave an optimal balance between novelty and familiarity. What we choose to consume and share with others, in turn, drives cultural evolution. But what if that conventional wisdom is wrong? An analysis based on data from a massive online fan fiction (fanfic) archive contradicts this so-called "balance theory," according to a paper published in the journal Humanities and Social S
