Byakugan Scan — Instant, in-memory screen OCR, QR code, and barcode scanner for macOS built with Swift 6.0 and Apple Vision Framework. Zero telemetry, sub-50ms hotkeys.

aritrosaha2025@gmail.com (Aritro Saha) — Wed, 28 Oct 2026 00:00:00 GMT

Byakugan Scan is a native macOS menu bar utility for instant, in-memory screen OCR, QR code, and barcode recognition. Unlike conventional screenshot OCR tools that write temporary image files to disk and trigger Spotlight or media analysis daemons, Byakugan Scan captures selected screen regions directly into NSPasteboard memory as a CGImage buffer and processes them on the Apple Neural Engine in under 50ms—with zero temporary files, zero network calls, and zero external Swift package dependencies.

Quarantine — Zero-dependency dead-letter queue and fault-tolerance library on PyPI. Wrap Python loops with @quarantine to isolate errors without crashing batch jobs.

aritrosaha2025@gmail.com (Aritro Saha) — Wed, 28 Oct 2026 00:00:00 GMT

quarantine is an open-source, zero-dependency Python library that brings dead-letter queue resilience to regular loops and batch data pipelines. When processing thousands of records (e.g., CSV ingestion, scraping, API syncing), an unexpected exception at item #5,247 no longer crashes the entire multi-hour run. quarantine safely isolates the failing item, captures the error and full execution state to disk, and keeps the loop running.
