KonomiTV is a modern, full-stack online PVR/streaming server tailored for Japanese digital television (GR, BS, CS, BS4K). In production, it serves as a live TV player with hardware-accelerated transcoding (QSV, NVENC, VCE, FFmpeg), a complete EPG and recording scheduler, and deep social media integration (Twitter/X, Bluesky, Niconico Jikkyo). The system acts as a modern web frontend for the traditional EDCB and Mirakurun TV middleware. The backend is a Python FastAPI application executing complex pipelines for MPEG-TS parsing, live encoding, and metadata analysis. The frontend is a Vue 3/TypeScript Progressive Web App with offline storage via Service Workers. The codebase exhibits high craftsmanship in its low-level protocol interactions: it contains a complete reverse-engineered binary protocol parser for EDCB, an undocumented Twitter GraphQL scraper, and zero-dependency keyframe seekers for MPEG-TS and MP4 containers. While primarily an application, it incorporates significant reverse-engineering and data processing research, including automatic CM detection, computer vision-based thumbnail scoring, and BML data broadcasting support. The architecture is well-structured but heavily coupled to the Japanese TV ecosystem and multiple fragile third-party dependencies (custom binary forks, hardware-specific drivers, browser automation for social feeds). These dependencies introduce medium technical drift, but the project is actively maintained with thorough CI/CD and regular third-party updates.
FileCodeBox is a file and text sharing service built with FastAPI and Tortoise ORM. It allows users to upload files or text accessible via short codes, with features including time/count-based expiration, chunked uploads, pre-signed URLs for direct cloud storage uploads, and an admin dashboard for management. The architecture uses a modular design with separate apps for base functionality and admin, storage abstraction for multiple backends (local, S3, OneDrive, WebDAV, OpenDAL), and background tasks for cleanup. Key entry points include main.py (FastAPI setup), apps/base/views.py (public sharing endpoints), and apps/admin/views.py (admin interfaces). The service demonstrates solid engineering practices with reusable components like storage abstraction and security headers, though some areas like settings management and rate limiting show opportunities for improvement in distributed environments.
