Toobmap reads video metadata and captions to identify places and match them to the video timeline. The web app and browser extension share the same location pipeline. The extension adds a map to YouTube’s sidebar.

• I replaced rule-based place extraction after finding too many exceptions across videos
• Coordinates from metadata appear first. An LLM refines the locations in the background
• Captions connect locations to timestamps, with chapter markers as a fallback

The map uses NBIM’s annual CSV of real estate holdings. The main challenge was turning inconsistent addresses into accurate coordinates. I added a geocoding cache, checks for misplaced results, and a manual correction pass.

• 1,389 properties · 245 cities · 15 countries (2025 dataset)
• Basemap falls back through three providers mid-session if a tile request fails
• Open source, MIT, built entirely from public NBIM data

Backups, video conversions, and training runs can often wait until electricity is cheaper. You set a deadline, such as 07:00, and the scheduler uses Nord Pool prices to decide when to start.

• Rechecks every 60 seconds as new prices become available
• Scheduling decisions are tested independently of the clock and database
• Cost estimates include grid tariffs, electricity tax, and strømstøtte
• The repository documents the limits of the expected savings in docs/CRITIQUE.md
