Generate random points inside a sphere

Generating random points inside a sphere of any dimension.

The customary way to generate points on a sphere in n dimensions is to generate points from an n-dimensional normal (Gaussian) distribution and normalize by dividing by the length. And the way to generate samples from an n-dimensional normal is simply to generate a list of n one-dimensional normals…

The Psychology of Choice: How Much Freedom Do Customers Really Want?

Retailers have long assumed that the bigger the range, the happier the customer. Endless shelves, multiple variants, and every possible option should, in theory, increase satisfaction. Yet the evidence is more nuanced. Recent research shows that in some contexts, larger…

Beyond Von Neumann: Toward a unified deterministic architecture

The mechanism behind this is a time-resource matrix: A scheduling framework that orchestrates compute, memory and control resources across time. Much like a train timetable, scalar, vector and matrix operations move across a synchronized compute fabric without pipeline stalls or contention.
By predicting exactly when data will arrive — whether in 10 cycles or 200 — Deterministic Execution can slot dependent instructions into the right future cycle. This turns latency from a hazard into a schedulable event, keeping the execution units fully utilized and avoiding the massive thread and…
