Previously, we discussed the limitations of assuming a default pinhole model in camera modeling, offering an alternative formulation using the unit sphere instead of the normalized image plane. Continuous optimization algorithms in robotics often involve minimizing errors or risks. In Differential Geometry, traveling efficiently on the unit sphere involves following geodesics or great circles rather […]

John Graham-Cumming tackled the issue of Steve Ballmer’s incorrect binary search interview question. While the expected value of the game is seemingly $952, interestingly, strategic variations by Ballmer can substantially affect this number. Binary search appears the best method at first, yet the game’s Nash equilibrium is more complex. The analysis delves into a simplified […]

In the world of quantum computing, the delicate nature of qubits presents a challenge due to their fragility and proneness to errors. Quantum Error Correction (QEC) plays a crucial role in correcting errors faster than they accumulate by combining multiple physical qubits into robust logical qubits. Google Quantum AI’s recent breakthrough showcases the successful operation […]

On June 30, 2012, the Quake3 network model was highlighted for its elegance. UDP/IP is favored over TCP/IP for its lower latency, with encryption and compression features. The server side efficiently sends updates to clients using snapshots and memory introspection. Clients receive gamestate updates while servers manage propagating gamestate accurately. The system automatically generates partial […]

Dear Reader, the struggle to avoid building a compiler is real. Despite initial resistance to complicated tools like abstract syntax trees (ASTs), the journey ultimately leads to developing one’s own AST library to manage code transformation. Surprising challenges arise, such as adapting to older versions of a language and simplifying transpiled code to meet requirements. […]
