## Worth attention

- **1.15.7**
  https://github.com/crewAIInc/crewAI/releases/tag/1.15.7
  CrewAI 1.15.7 fixes Responses API/tool-calling failures, GPT-5.6 reasoning errors, and patches a Bedrock CVE.
- **SQLite WAL Mode Can Lock Short-Lived Readers**
  https://hynek.me/til/sqlite-read-only-wal-locked/
  Hynek shows WAL mode can still lock short-lived read-only SQLite readers; busy timeout or DELETE mode removed the errors.
- **The AI in my home inventory app costs me money every time someone taps it, and no subscription I modelled survived that. Here is what I shipped instead.**
  https://www.reddit.com/r/SaaS/comments/1v7sl6y/the_ai_in_my_home_inventory_app_costs_me_money/
  One founder found subscriptions failed for bursty AI usage and switched to metered credits plus an optional bring-your-own API key.
- **Show HN: Writemark, a dependency free web component for inline Markdown editing**
  https://news.ycombinator.com/item?id=49051130
  Writemark is a dependency-free Markdown editor web component with split/preview modes and 951 Playwright checks.
- **A garment factory was tracking 100 plus production processes in Excel. Replacing it taught me more about selling software than building it.**
  https://www.reddit.com/r/SaaS/comments/1v7thgw/a_garment_factory_was_tracking_100_plus/
  A small dev shop says fixed-price delivery and cheap open-source hosting eased buyer fear more than the app itself.
