Show HN: Fixing a single pointer bug unlocked 1M+ row JSON parsing on WindowsI've been building a cross-platform JSONL viewer app that handles multi-GB files. It worked perfectly on macOS (my development machine), but consistently crashed on Windows at exactly 2,650 KB. Here's the debugging journey and the tiny fix that made all the difference.The Problem- macOS: Handles 5GB+ files effortlessly - Windows: Crashes at 2,650 KB every time - Same codebase, cross-compiled from Mac Silicon to Windows using MinGWThe InvestigationAdded detailed logging to track execution. The crash happened during string interning after successfully parsing ~6,000 rows. Not during parsing, not during file I/O, but during the merge phase.The Root CauseMy StringPool class used std::unordered_map to deduplicate strings. The string_views pointed into a std::vector.When the vector grew and reallocated, all the string_view keys became dangling pointers. The hash map was full of invalid references.Why did it work on macOS? Different memory allocator behavior, different default stack sizes (8M

Show HN: Undatas.io – A pay-on-accept document parsing APIHey HN, Alex here, founder of undatas.io.Our journey started from a place of deep frustration with RAG (Retrieval-Augmented Generation). I was helping companies build internal knowledge bases on their own data, and the promise was huge. But in practice, the results were often mediocre. Important information was frequently missed during retrieval, and we kept hitting dead ends.After endless debugging, we realized the problem wasn't the LLM; it was classic "garbage in, garbage out." We traced the retrieval failures back to the very first step: document parsing.Whether we used open-source libraries or expensive paid APIs, the story was the same. Precision was lost. Key phrases, critical numbers, and entire table rows would just vanish during the parsing process. We spent countless hours manually comparing the original PDFs to the parsed output to find what went wrong. It was a soul-crushing, time-consuming nightmare.The biggest pain points were:1. Complex Tables: Most tools collapsed when
