The PostgreSQL parameter scram_iterations is not really a server setting but a default baked into each password at creation time. Changing it and reloading does nothing to existing passwords, since the iteration count is stored inside each password string. Raising it shifts CPU cost to connecting clients, not the server: testing showed clients spending 0.05 to 18.3 seconds per connection as iterations rose from 1 to 1,000,000, while server CPU stayed flat. A related flaw, CVE-2026-14672, let attackers detect which usernames exist by comparing the iteration count returned for real versus nonexistent roles; it was fixed in PostgreSQL 18.6, 17.11 and 16.15. The advice: leave generated application passwords at 4096 and reset every password on a cluster after raising the value.

pwn.college is a free, hands-on education platform for learning core cybersecurity and hacking skills, maintained by a team at Arizona State University. Learners progress through belt ranks, starting with a 'white belt' and earning belts through practice. Hackers continue beyond the platform to 'brown belt' and eventually 'black belt' status, which must happen outside the dojo. The site powers much of ASU's cybersecurity curriculum and asks users not to post writeups or walkthrough videos of challenge solutions. It points learners toward CTFtime.org for Capture The Flag events and a GitHub list of wargames for further practice. The underlying infrastructure is open source and accepts pull requests, though some modules remain closed-source.

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
RAG (Retrieval-Augmented Generation) và Agentic RAG là hai phương pháp xử lý thông tin khác nhau trong lĩnh vực AI. RAG hoạt động bằng cách truy vấn vector database để tìm thông tin liên quan trước khi tạo câu trả lời, ví dụ như với vector database có thể chứa hàng triệu document embeddings. Agentic RAG thêm vào một agent có khả năng tự suy luận, cho phép hệ thống tự động xác định cần tìm thêm thông tin hay không, như trường hợp của OpenAI's GPT-4 với function calling. Sự khác biệt chính là Agentic RAG có khả năng tự chủ trong việc quyết định cần làm gì tiếp theo thay vì chỉ phụ thuộc vào kết quả truy vấn ban đầu. Đây là kiến thức quan trọng để hiểu sự tiến hóa từ RAG cơ bản đến các hệ thống thông minh hơn có khả năng tự điều chỉnh.
Bài viết này giúp bạn hiểu rõ sự khác biệt cơ bản giữa RAG và Agentic RAG để áp dụng hiệu quả vào các dự án AI.
