    MilleMiglia: A realistic instance generator for middle-mile logistics

    MilleMiglia is an open‑source C++ generator that creates realistic, privacy‑preserving middle‑mile logistics instances (space‑time graphs with fixed schedules, throughput limits, and synchronization constraints). It uses data‑driven spatial, demand, and rotation distributions, serializes with protobuf, and ships small files for small‑toy to continent‑scale problems, enabling both exact/heuristic…

    GSoC 2026: Improving HLSL Support in clangd

    The GSoC 2026 project identified and closed numerous gaps in clangd’s HLSL support. By performing a systematic gap analysis, the author authored an RFC, opened 11 GitHub issues, and landed multiple PRs that improve hover (semantic annotations, out/inout parameters, swizzles, RootSignature, register ranges) and code‑completion (attributes, register, semantic annotations, swizzle). The work also ex…

    How LLMs Can Find a Needle in a Haystack

    The post explains how retrieval‑augmented generation (RAG) lets LLM‑based assistants answer questions from private corpora. It covers chunking documents into passages, embedding queries and chunks, similarity metrics, and the trade‑offs of different vector indexes (flat, IVF, HNSW). The focus is on practical design choices rather than new research.

    Advancing AI for biology: Teaching models to design and characterize antibodies

    Amazon Bio Discovery developed three AI models: MochiBind for fast, sequence-based antibody binding ranking, CA-MAP for context-aware developability prediction robust to batch effects, and an agent-guided system for de novo antibody design. These advancements aim to accelerate and improve the accuracy of antibody drug discovery, with experimental validation for a novel cancer target.
