Ask HN: Multi dimensional sort (beyond Hilbert curve)
My point is about structuring and indexing an arbitrary dataset, for preprocessing before eg segmentation/clustering, neighbor querys...In 1D, sorting is trivial because scalar values have a total, unambiguous order. In 2D and higher dimensions, there is no single way to order points, and points can't all be compared >=/<= in a consistant way. Space-filling curves like Hilbert or Z-order curves still can order Nd points by mapping them to a 1D index, but flattening the space
The Cost of Seamlessness
The Hidden Cost of Frictionless Technology Taotuner — 2026I recently asked an AI assistant for restaurant recommendations. It listed five places, complete with ratings, distance, and popular dishes. I picked one, went, had a fine meal. Later, when a friend asked what I'd eaten, I couldn't remember the name of the restaurant.The experience wasn't bad. It was frictionless. And it left almost no trace.We've built tools that eliminate the gap between want and satisfaction, questi
Show HN: I made an algorithmic arena game with physics in 3D
Hey,I finally dare to raise the curtains to my 3D physics-modeled arena game, where players' algorithms fight and perform tasks.The arena treats algorithms as a black box, meaning that the implementation of algorithms is in the free hands of the players via the Algohol API. Algohol is roughly in the same context as Screeps or Battlesnake, but brings its own dimension to the genre.At the moment the only world is energy economy based SciFI, but there will be Terra (traditional kinetic combat

NTHU Joins European Space Mission to Help Unlock the Mysteries of Galaxy Evolution by 2030
HSINCHU, Taiwan, July 24, 2026 (GLOBE NEWSWIRE) -- Andrew Cooper, Associate Professor at National Tsing Hua University's Institute of Astronomy, has joined the European Space Agency's newly approved ARRAKIHS mission, which will launch a space telescope in 2030 to explore the faint outermost regions of galaxies that have long remained beyond the reach of observation. As Co-Chair of the Galaxy Science Working Group, Cooper leads an NTHU research team in developing theoretical models using high-performance computing to help the international collaboration interpret the mission's future observations and, for the first time, reconstruct the unique formation history of individual galaxies.
