GUI Fact of The Day

Phase 1 — Source adapters & normalization

• Implement ≥4 adapters (e.g., domain-specific RSS/JSON sites)
• Query by user-defined domain (astronomy, biology, etc.)
• Normalize common fields, such as title, description, url, image_url, published_at, source
• Add short request timeouts

Functional result: A test run fetches recent items for chosen domains from ≥4 sources and prints normalized entries.

Phase 2 — Aggregation & interval fetch

• Merge results per domain; remove duplicates (URL/title key)
• Sort newest-first; cap items per domain
• Interval scheduler (e.g., every 15 min) triggers background fetch
• Keep a small in-memory cache to avoid rapid refetch

Functional result: On a timer, new items are aggregated, de-duplicated, and ready for display without blocking the app.

Phase 3 — GUI (Tkinter) feed viewer

• Domain selector, interval control (15/30/60), “Refresh now”
• Scrollable list of cards: title, source, time, description, optional image
• Click to open article in browser
• Non-blocking data fetch in background

Functional result: User selects domains and sees clickable, up-to-date cards with titles, descriptions, and images where available.

Phase 4 — Auto-refresh UX & Error handling

• Auto-update feeds at the chosen interval
• Display the “Last update” time
• Brief banner on fetch failure; keep last good results
• Lightweight preferences (domains, interval) saved to a small config

Functional result: Feeds update on schedule, the timestamp reflects updates, errors show briefly while prior results remain visible across restarts.
