VentureBeat — AI: One AI module faked 86% of a pipeline's accuracy gains by feeding another the answers. A retrieval-augmented generation (RAG) system is built to answer strictly from the documents it retrieves. But when engineers optimize these AI pipelines end-to-end, the reader module can learn a shortcut: instead of relying on retrieved evidence, it starts answering from its own internal memory — w ZDNet — AI: AI-enriched Linux 7.2 delivers cache-aware scheduling - here's everything new. The latest kernel also brings filesystem and I/O improvements and substantial new support across AMD, Intel, Apple, Nvidia, USB4, and laptop hardware.

With AI-driven RAM shortages pushing Raspberry Pi prices sky high, here's how to repurpose your old handset into a portable powerhouse for your projects.

Today's PM news comes from Lenny's Newsletter. The story is 🎙️ How I AI: How a solo founder used Codex and ChatGPT to launch a fashion brand without engineers. For a senior PM, the key takeaway is to watch how product decisions and strategy plays out in practice — not just the headline, but the reasoning behind it.

Today's PM learning comes from Lenny's Newsletter. The core idea is 🎙️ How I AI: How a solo founder used Codex and ChatGPT to launch a fashion brand without engineers. What matters for a senior PM is translating the idea into a repeatable habit: define the user problem clearly, pick a metric that actually reflects value, identify the riskiest assumption, and make the next experiment small enough to learn quickly. Good PM content is rarely magic. It is usually disciplined prioritisation dressed up in nicer prose.
