Claude Code Unpacked: A visual guide
A beautifully annotated visual map of Claude Code's half-million-line codebase. The HN thread is a direct companion to the ongoing source-leak story — together they reveal the raw, unglamorous architecture of an AI agent: frustration regexes, context sanitizers, tool-retry loops, and state rollbacks. One commenter put it plainly: "we're still herding cats with massive code volume." Making a probabilistic LLM behave deterministically is a massive state-management nightmare.
Claude Wrote a Full FreeBSD Remote Kernel RCE (CVE-2026-4747)
An AI agent autonomously found a real kernel-level buffer overflow in FreeBSD's RPCSEC_GSS implementation — a stack buffer of 128 bytes into which an entire credential body is copied without bounds checking, yielding remote code execution on an NFS server. This isn't a CTF exploit or a controlled demo. It's a CVE in production kernel code, found by asking a model to look. The tool became the vulnerability researcher.
Is BGP Safe Yet?
A test-your-ISP tool for measuring whether your network operator is vulnerable to BGP route hijacking. The internet's core routing protocol was designed on trust between peers, and decades later that trust is still a surface for exploitation. It runs in your browser — no account, no probe — and tells you in seconds whether your ISP's route announcements are being validated.
