Try itPostgres 18’s new file_copy_method = clone setting lets you give every git worktree its own copy of your database in seconds, without eating up your disk.
This week vector search opened the MySQL Contributor Summit. A plugin started the fire, the M-ecosystem picked it up, the hyperscalers went native, and now the benchmark wars have begun.
json vs jsonb in PostgreSQL 17 and 18, measured on six document shapes: when jsonb is 23% smaller or 41% larger, read speed, GIN, and what it changes.
Two incompatible migrations merge clean, then resolve in the database — as a failed deploy in one environment and a healthy one in another, decided by apply order. The idempotent version is worse: every statement succeeds and the schemas silently diverge.
OccupySaaS is a protest movement in code: laid-off developers building clean-room, open-source, drop-in replacements for the SaaS giants. First up: ZeroAuthy (Auth0) and SalesCompel (Salesforce).
An API can save an order and crash before publishing the message that tells other services about it.
If you have certain lines of code that repeat over and over again in a project, there's a pretty standard solution for it: using a function. But what about when you have the same project file setup th
Bối cảnh triển khai AI mà không có bước review rủi ro giống như thiếu một WHERE clause trong SQL có thể dẫn đến đêm dài khắc phục sự cố. Nguyên nhân kỹ thuật nằm ở việc các model AI có thể tạo ra dữ liệu không mong muốn khi không có bộ lọc phù hợp. Hệ quả có thể rất nghiêm trọng khi hệ thống AI vô tình tạo ra nội dung độc hại, sai lệch hoặc vi phạm chính sách. Đáng học hỏi là bài nhấn mạnh việc xác định rõ vị trí của cơ chế "phanh" (brake) trong hệ thống AI và ai chịu trách nhiệm kiểm soát nó.
Bài viết này giải thích tại sao thiếu bước kiểm duyệt trong AI sản xuất có thể dẫn đến hậu quả nghiêm trọng như lỗi query SQL không có WHERE clause.
