I used Claude Code to reverse engineer a 13-year-old game binary and crack a restriction nobody had solved — the community is losing it

"I want to share something I built with Claude Code this past week because I think it shows what AI-assisted development can actually do when pointed at a genuinely hard problem. Disney Infinity 1.0 (2013) is a game where you place physical figures on a base to play as characters. Each character is ..."

A Quantitative Characterization of Forgetting in Post-Training

"Continual post-training of generative models is widely used, yet a principled understanding of when and why forgetting occurs remains limited. We develop theoretical results under a two-mode mixture abstraction (representing old and new tasks), proposed by Chen et al. (2025) (arXiv:2510.18874), and..."

[P] I got tired of PyTorch Geometric OOMing my laptop, so I wrote a C++ zero-copy graph engine to bypass RAM entirely.

"If you train Graph Neural Networks on large datasets (like Papers100M), you already know the pain: trying to load the edge list and feature matrix usually results in an instant 24GB+ OOM allocation crash before the GPU even gets to do any work. I just open-sourced **GraphZero v0.2**, a custom C++ d..."

đŸŽ¯ GNN neighbor sampling â€ĸ Memory-efficient data structures â€ĸ CPU/CUDA message passing ops
đŸ’Ŧ "np.memmap is fine for basic arrays, but using it for GNN neighbor sampling ("fancy indexing") triggers implicit RAM copies in Python, causing OOMs anyway." â€ĸ "Another easy win from a throughput perspective is if you use any edge -> node pooling message passing ops, you can write a pretty nice CPU/CUDA implementation that bypasses storing the full edge feature list in memory and instead consumes on-the-fly."

Cross-Context Review: Improving LLM Output Quality by Separating Production and Review Sessions

Matching Features, Not Tokens: Energy-Based Fine-Tuning of Language Models

We introduce a feature-matching objective for language-model fine-tuning that targets sequen..."
