• Floating-Point Printing and Parsing Can Be Simple and Fast

  • Fast unrounded scaling enables efficient floating-point printing and parsing, achieving speeds surpassing existing algorithms like Dragon4 and Grisu3, with a Go implementation expected in Go 1.27 by August 2026.

• [R] I solved CartPole-v1 using only bitwise ops with Differentiable Logic Synthesis

  • The author achieved a perfect score on CartPole-v1 by distilling the control policy into four bitwise rules using Differentiable Logic Synthesis, treating the state as a boolean input vector rather than numerical values.

• Waypoint-1: Real-Time Interactive Video Diffusion from Overworld

  • Waypoint-1 is a real-time interactive video diffusion model that allows users to control and prompt video generation through text and inputs, creating immersive experiences with zero latency.

• Wilson Lin on FastRender: a browser built by parallel agents

  • FastRender is a web browser developed using 2,000 parallel agents, showcasing the potential of autonomous coding in complex tasks, with nearly 30,000 commits made during its development.

• [R] Teacher-Free Self-Distillation: Fixing the Softmax "Infinite Gap" with Euclidean alignment

  • Teacher-Free Self-Distillation (TFSD) addresses the "Infinite Gap" problem in Cross-Entropy loss by employing negative squared Euclidean distance, which bounds logits and prevents infinite values during optimization.

• [P] motcpp; I rewrote common 9 MOT trackers in C++17 achieving 10–100× speedup than Python implementations in my MOT17 runs!

  • The motcpp library, an open-source C++17 project, achieves 10–100× speedup over Python implementations for multi-object tracking in video frames, enhancing real-time performance and deployment ease.
