Much improved new version. Search for words similar to the query. For example, "death" will find "death", "dying", "dead", "killing"... Incredibly useful for exploring large text datasets where exact matches are too restrictive.

Hi, I recently published my ebook on GNU awk one-liners [1]. It starts from the basics of awk syntax and then discusses one-liner examples. There's a chapter on regular expressions as well. The github repo has the details on how to get the PDF version, all the example files and code snippets used in the book, sample chapters as well the markdown source used to generate the PDF. I made all my ebooks [2] free last month amidst the pandemic fears. These include GNU grep & ripgrep, GNU sed and three books on regular expressions (Python, Ruby, JavaScript). I'd appreciate your feedback and hope…

An extension of regular expressions for text editing, with a grep-like command-line tool. If you, like me, struggle with group logic in regular expressions, you might find it useful. I wanted to do this for a very long time. It is more of a sketch or prototype. I'd really appreciate your feedback!

Hi HN, I built an open-source AI agent that has already indexed and can search the entire Epstein files, roughly 100M words of publicly released documents. The goal was simple: make a large, messy corpus of PDFs and text files immediately searchable in a precise way, without relying on keyword search or bloated prompts. What it does: - The full dataset is already indexed - You can ask natural language questions - Answers are grounded and include direct references to source documents - Supports both exact text lookup and semantic search Discussion around these files is often fragmented. This…

This is a vector index I built that supports insertion and k-nearest neighbors (k-NN) querying, optimized for GPUs. It operates entirely in CUDA and can process queries on half a billion vectors in under 200 milliseconds. The codebase is structured as a standalone library with an HTTP API for remote access. It’s intended for high-performance search tasks—think similarity search, AI model retrieval, or reinforcement learning replay buffers. The codebase is located at https://github.com/rodlaf/BinaryGPUIndex.
