Earlier today[1], helped my son with a raycasting issue and then ended up updating/extending the 2D shape intersection function in thi.ng/geom, which now also supports ray intersections with nested shape groups/hierarchies (via same single function call) and a new option to return _all_ intersection poi…

2D line art animation showing some shapes (rectangles, circles, hexagon, wavy polyline...) and a line/ray rotating anti-clockwise. The intersection points between that ray and the static shapes are highlighted as pink dots. Each dot also has a label showing the distance from the ray origin (center of image). Depending on the angle and shapes intersected, the number of intersections varies (max. approx. 10 points)

LACS: Learning-Augmented Algorithms for Carbon-Aware Resource Scaling with Uncertain Demand
Motivated by an imperative to reduce the carbon emissions of cloud data centers, this paper studies the online carbon-aware resource scaling problem with unknown job lengths (OCSU) and applies it to carbon-aware resource scaling for executing computing workloads. The task is to dynamically scale resources (e.g., the number of servers) assigned to a job of unknown length such that it is completed before a deadline, with the objective of reducing the carbon emissions of executing the workload. Th…
