Pwn.college

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.

Goodbye Claude, Hello Pi

A longtime Claude Code user is switching to the open source harness Pi after accumulating frustrations. Claude Code only lets one session connect to the IDE at a time, a bug reported since December 2025 and closed as a duplicate. The author counts 244 Claude Code releases this year, with over three-quarters changing the system prompt or tool descriptions. Despite trimming 80% of the system prompt, the default Bash tool description still runs almost 3,000 tokens. The author calls Claude Code a product without strong direction and says Pi has been smooth sailing since the first few days.

Claude Code's creator says better prompts need just 3 things, so I tested his approach

Bối cảnh của bài viết khám phá liệu chúng ta có đang quá tư duy hóa việc tạo prompt hay không. Nguyên nhân kỹ thuật được nêu ra là một phương pháp đơn giản chỉ cần 3 yếu tố: context, instruction, và input, được đề xuất bởi nhà sáng tạo Claude Code. Hệ quả khi áp dụng phương pháp này là việc tạo prompt hiệu quả trở nên dễ dàng hơn nhiều so với những cách phức tạp trước đây. Điều đáng học là ngay cả những AI model mạnh nhất hiện nay như Claude 3 hay GPT-4 vẫn phản ứng tốt với prompt có cấu trúc đơn giản này.

Bài viết này giúp bạn hiểu ra cách đơn giản hóa việc tạo prompt hiệu quả chỉ với ba yếu tố cơ bản.
