A delivery app engineer discovered that their Redis caching layer for route estimates was inefficiently distributing keys across hash slots, causing MGET operations to be split into individual requests. By learning how Redis hash slots work and restructuring their key format, they were able to optimize the batching of multi-key commands to improve latency.
ArrowSpace successfully processed 100,000-dimensional biomarker data from the Dorothea dataset, scaling to 800 samples in 41-110 seconds with over 600× memory compression. The system achieved 5-22% graph density through parameter sweeps, with TauMode computation being the critical bottleneck at 62% of runtime. Johnson-Lindenstrauss projection and k-NN connectivity emerged as key factors controlling build time and graph density respectively.
VoltGrid is a software interposition engine that mitigates dangerous power surges in GPU clusters by staggering synchronous current draws across accelerators, reducing voltage droop by 97.52% without sacrificing compute performance or requiring code changes.
HeronLoom is a tool that transforms social media posts and documents into a 3D graph for analyzing trends, sentiment, and predictions using iterative clustering and LLM-based analysis. It tracks how topics and narratives evolve over time while preserving conflicting interpretations and maintaining evidence-based confidence scores with citations to source material.
Reletter is a tool that creates a 3D map of newsletter connections by identifying when newsletters link to the same pages. It tracks over 7 million newsletters across multiple platforms including Substack, Beehiiv, Kit, Ghost, and LinkedIn, processing approximately 350,000 new issues weekly.
