A developer shares their experience migrating a personal website from RSS to Atom feeds in 2026, describing it as long-overdue 'impulse coding'. The post covers the key technical differences between RSS and Atom, including Atom's requirement for URI-based entry IDs (using UUID URNs), RFC 3339 timestamps, and explicit content type declarations. A shell command using sed and uuidgen was used to replace old key attributes with UUIDs. To avoid spamming subscribers with re-appearing old posts due to changed IDs, a workaround was implemented to only include new posts in the feed going forward.
