The article outlines a technical framework for reducing LLM costs through tiered response caching. It details how to implement exact-match and semantic-match strategies to avoid redundant model inferences.

A significant vulnerability in Coldcard hardware wallets' firmware led to a massive reduction in entropy, enabling attackers to steal over $100 million in Bitcoin. The flaw has prompted the cryptocurrency community to move away from trusting hardware-based random number generators in favor of auditable, physical entropy methods like dice rolling.

A critical vulnerability in Ollama allows unauthenticated attackers to trigger an out-of-bounds heap read via malicious GGUF files. This exploit can expose sensitive information like user messages and system prompts by leaking them into newly created model files.
