Project Maven: The Architecture of Algorithmic Warfare Prologue: The Silent Transformation of War War has always evolved with technology—from steel to gunpowder, from mechanization to nuclear deterrence. Yet no transformation has been as subtle, pervasive, and consequential as the one now unfolding: the transition from human decision-making in warfare to algorithmic mediation of violence. At the center of this transformation lies Project Maven. What began as a technical solution to an intelligence bottleneck has evolved into something far more consequential: A system that compresses human judgment into machine-speed decision loops—reshaping not only how wars are fought, but how life-and-death decisions are made. This documentary report examines Project Maven from its origins in 2017 through its global deployment in 2026. It traces the technical evolution, corporate part...

Scenario Listen to this story: a boy and his father, a computer programmer, are playing with wooden blocks. They are building a pyramid. Their pyramid is a bit weird, as it is actually a pyramid-shaped wall - it's flat. The pyramid is stacked according to one simple principle:  👉 each lower layer contains one block more than the layer above 👈 . The figure illustrates the rule used by the builders: building blocks Your task is to write a program which reads the number of blocks the builders have, and outputs the height of the pyramid that can be built using these blocks.
