Researchers found a 55-year-old bug hiding in the Apollo 11 guidance computer, Claude Code users are getting locked out for hours, and Cloudflare just published their roadmap to post-quantum security. Here's what matters today.
An Undocumented Bug on the Dark Side of the Moon
A team at JUXT discovered a previously undocumented bug in the Apollo 11 guidance computer code. The bug existed in the original flight software and went unnoticed for over five decades.
The discovery came from a deep dive into the AGC (Apollo Guidance Computer) source code that's been publicly available on GitHub. What makes this interesting isn't just the historical curiosity. It's a reminder that even the most scrutinized, mission-critical code can harbor subtle issues.
Claude Code Users Locked Out for Hours
Anthropic's Claude Code is experiencing significant issues with rate limiting that's locking users out for extended periods. A GitHub issue documents the problem, with developers reporting multi-hour lockouts during active coding sessions.
This follows earlier reports about Claude Code becoming unusable for complex engineering tasks after recent updates. For teams relying on AI coding assistants, these reliability issues highlight the importance of having fallback workflows.
Cloudflare's 2029 Post-Quantum Target
Cloudflare published their roadmap for achieving full post-quantum security by 2029. The plan outlines a phased migration path for upgrading cryptographic systems before quantum computers can break current encryption.
The timeline aligns with estimates from cryptography engineers about when cryptographically relevant quantum computers might emerge. If you're building systems that need to protect data for years or decades, this migration should be on your radar.
Why One Developer Dropped Cloudflare for Bunny.net
A detailed post explains why one developer switched from Cloudflare to Bunny.net for their CDN needs. The reasons include pricing transparency, simpler configuration, and better fit for specific use cases.
It's not an anti-Cloudflare piece. It's a practical look at how different infrastructure choices serve different needs. Worth reading if you're evaluating CDN options.
Google Open-Sources Agent Orchestration Testbed
Google released Scion, an experimental testbed for agent orchestration. The project provides infrastructure for testing how multiple AI agents coordinate and communicate.
As AI agents become more prevalent in development workflows, tools for testing multi-agent systems become essential. Scion gives researchers and developers a sandbox for exploring these patterns.
GLM-5.1: Long-Horizon Task Performance
Z.AI released GLM-5.1 with improvements focused on long-horizon tasks. The model shows better performance on complex, multi-step reasoning problems that require maintaining context over extended interactions.
