Hard-kill invocation timeouts (the host never trusts user code to exit), warm-container idle eviction via a background reaper, per-container event queues that stop cross-container event stealing, per-function warm pools so concurrent invokes fan out and callers block when the pool is saturated, and the Lambda Runtime API long-poll loop (/next then handler then /response). A FastAPI host process orchestrates the whole container lifecycle. https://github.com/himanishpuri/PolyDub 6a9d90999a33489da8cb8c43 Sun, 06 Sep 2026 21:36:08 GMT An automated video-dubbing pipeline with voice cloning and multi-language support. It transcribes with OpenAI Whisper, translates subtitles offline with Argos Translate, synthesises voice-cloned speech in the target language with Coqui XTTS v2, and reassembles a dubbed video with pitch-preserving time-stretch. Optional Demucs source separation keeps the original score under the cloned speech. Whisper and XTTS load once per run, artifacts are cached by audio fingerprint so failed runs resume, and the device (CUDA / MPS / CPU) is auto-detected. Ships as a one-command Docker image with a Gradio web UI. https://continuum.himanishpuri.dev 6a9d90999a33489da8cb8c42 Sun, 06 Sep 2026 21:36:08 GMT A persistent, agentic wellbeing and habit-planning assistant — deliberately not a chatbot with a database. It recalls your history and long-term memory, compares adherence with deterministic statistics rather than a model guess, explains what it noticed with concrete evidence, then proposes a plan change and waits for your approval. On approval it acts for real: a versioned plan update, an audit event, and a scheduled follow-up run by a background job that later adapts the plan or decides no intervention is needed. Next.js with Genkit/Gemini and Firebase auth. Non-clinical. https://github.com/himanishpuri/helix_chatbot 6a969590c10b6954e7f110db Tue, 01 Sep 2026 09:06:24 GMT Fully self-hosted RAG chatbot with zero external LLM API calls — inference runs locally via llama.cpp, eliminating per-token cost and external data exposure. A semantic response cache cuts repeat-query latency from 2.5s to 0.3s, and history-aware query rewriting keeps follow-up questions reliable. A two-process design (SSE gateway + Redis-backed async workers) streams tokens live with cancel-on-disconnect. https://github.com/himanishpuri/AcousticDNA 6977b750c2edc4caaa6f6ff6 Tue, 27 Jan 2026 00:22:00 GMT Audio recognition system built from scratch in Go with WebAssembly support. Implements time-coherence voting algorithm to match songs from short audio clips using spectral fingerprinting. Features include client-side WASM processing, REST API server, CLI tool, Docker deployment, and YouTube integration. Custom DSP pipeline performs STFT analysis, peak extraction, and combinatorial hashing. Optimized for performance with batch SQL queries, handles 1000+ songs, and achieves matching with data reduction through local hash computation. https://kompte.com/ 68ede4d0e1e4977d6eb1fd51 Tue, 14 Oct 2025 05:51:12 GMT Kompte is a sports event hosting and management platform that allows users to create, manage, and participate in various sports events. It features user authentication, event creation, registration, and a leaderboard system as well as tournament bracket generation. https://talkeys.xyz 68ede4d0e1e4977d6eb1fd50 Tue, 14 Oct 2025 05:51:12 GMT Talkeys is a social-first event discovery platform that enables users to find, host, and attend events, while engaging in anonymous, chat-based communities. Integrated payment gateway and handles frontend and backend, integration and features. https://www.thapargo.com/ 68ede4d0e1e4977d6eb1fd52 Tue, 14 Oct 2025 05:51:12 GMT ThaparGo is a ride-sharing platform designed specifically for Thapar University students, facilitating easy and secure carpooling. It allows users to post and find rides, ensuring a convenient travel experience within the campus community.
