🥈 Use subagents and custom agents in Codex
Use subagents and custom agents in Codex — simonwillison.net · 8h ago · 🤖 AI / ML
OpenAI Codex now offers general availability of subagents, enabling users to delegate tasks to specialized agents such as ‘explorer’, ‘worker’, and ‘default’. The ‘worker’ subagent is optimized for running many small tasks in parallel, similar to Claude Code’s approach, though distinctions between ‘worker’ and ‘default’ remain somewhat unclear. Codex also supports the creation of custom agents, allowing for tailored workflows and automation. These enhancements provide greater flexibility and scalability for complex coding and data processing tasks.
💡 Why read this: Explore this article to learn how subagents and custom agents in Codex can streamline and parallelize your automation and development workflows.

5. Quoting A member of Anthropic’s alignment-science team
Quoting A member of Anthropic’s alignment-science team — simonwillison.net · 9h ago · ⭐ 21/30
A member of Anthropic’s alignment-science team explains that the purpose of the ‘blackmail exercise’ was to create vivid, relatable scenarios that make AI misalignment risks tangible for policymakers. By designing exercises with visceral impact, the team aims to bridge the gap between abstract alignment theory and practical policy concerns. The approach is intended to foster a deeper understanding of generative AI risks among those unfamiliar with technical details. The key takeaway is that effective communication of AI risks requires concrete, memorable examples.

6. Quoting Guilherme Rambo
Quoting Guilherme Rambo — simonwillison.net · 10h ago · ⭐ 21/30
Guilherme Rambo reveals that the MacBook Neo’s software-based camera indicator light operates within the secure enclave, providing security nearly equivalent to a hardware indicator. This design ensures that even a kernel-level exploit cannot activate the camera without the indicator appearing on screen, as the light is managed in a privileged environment separate from the kernel and rendered directly to the display hardware. The approach significantly reduces the risk of covert camera activation. The main point is that Apple’s implementation offers robust privacy protection through hardware-level isolation.

7. Cleaning old GPG RPM keys that your Fedora install is keeping around
Cleaning old GPG RPM keys that your Fedora install is keeping around — utcc.utoronto.ca/~cks · 5h ago · ⭐ 17/30
Long-lived Fedora installations accumulate outdated GPG (or PGP) keys in the RPM database, stored as pseudo-packages. This can lead to clutter or issues if a key becomes compromised or obsolete. The article provides a command to list all stored keys and discusses scenarios where cleaning up old keys is necessary for system hygiene and security. The main takeaway is that periodic key management is important for maintaining a secure and tidy Fedora environment.
