How to safely unsave Reddit posts and export your saved data first

Reddit does not appear to offer an official bulk unsave or multi-select option, so the documented method is unsaving items one at a time. Because unsaving has no documented undo, the article recommends requesting an official data export first, which Reddit says can take up to 30 days. Unsaving only removes an item from your saved list and does not delete the post or comment itself. The Saved page also appears to show a limited number of items, so older saves may not be visible there. The author advises against third-party scripts or automation, which Reddit's rules restrict, and promotes their own browser extension for organizing saves.

Queue Fan-Out Outperforms Monolithic Cron for Large Email Retry Workloads

The article argues that cron should only admit work, while a queue-backed worker sends each report email with bounded retries. Each job is keyed by report date and recipient or tenant ID, so redelivery under at-least-once semantics does not cause duplicate sends. Using a hypothetical 18,400-recipient digest that hits provider rate limits partway through, the author shows how a monolithic run forces risky restarts or manual cleanup. The approach lets operators retry only unfinished recipient jobs, and alerts can focus on exhausted attempts or message age rather than transient 429 responses. The piece also notes that payloads should stay small, since queue message bodies have size limits.

Oracle Adds Assistant to Investigate Project Cost Import Exceptions

Oracle is introducing a Project Cost Exceptions Assistant for Fusion Cloud Project Costing, slated for release in 27A. Project costs that fail validation during the Import Costs process remain unprocessed, which can complicate month-end close for project accountants. The assistant lets users search, categorize, and drill into these exceptions through natural-language requests and suggests possible resolutions based on the error type. It is designed for investigation rather than correction, so corrective changes must still be made through standard Oracle Fusion functions. The distinction matters because unresolved exceptions can delay reporting and downstream billing and revenue activities.
