Paul Graham GPT is a specialized AI-powered search and chat app built on a corpus of essays from Paul Graham, giving users the ability to query and discuss his writings in a conversational way. The repo stores the full text of his essays (chunked), uses embeddings (e.g. via OpenAI embeddings) to allow semantic search over that corpus, and hosts a chat interface that combines retrieval results with LLM-based answering — enabling RAG (retrieval-augmented generation) over a fixed dataset. The app uses a Postgres database (with pgvector) hosted on Supabase for its embedding store, making the backend relatively simple and accessible, and the frontend is again built with Next.js/TypeScript for a modern responsive UI. By pulling together search and chat, it creates a useful tool both for readers who want to revisit or explore Paul Graham’s ideas thematically, and for learners or researchers who want to query specific essays or concepts quickly.

DuMP3 is a duplicate and similar file finder. It finds exact duplicate binaries by hash, similar text files by substring content, images (JPG, BMP, GIF, PNG, etc) by color and audio files (MP3, WAV, OGG, etc) by wave data. Future: fonts, video.

DupLichaSe is a very fast Duplicate File Detector that uses inductive heuristics to detect duplicate files very fast; based on content! DupLichaSe stands out from EVERY other Duplicate file detection Software because of it's graph based semi-automatic selection system. ... after finding 100s of duplicate files, do you have to go through some manual and possibly laborious process of deleting the duplicates? ...or is there a way for the Software to learn and do most of it for you in a SAFE and RECOVERABLE MANNER? YES!! There is!! ...This Software will ALSO help you and delete duplicate files, after you must have taken action on a a FEW important files(i.e large files that are duplicates). ++Thanks to its trivial Graph based suggestion System
