HOW AGENTIC RAG WORKS

Standard RAG is a one-shot pipeline: query in, retrieve, generate. However, it breaks down the moment a question is ambiguous, the answer is spread across multiple sources, or the retrieved chunk looks relevant but isn't. Agentic RAG fixes this by adding an LLM in the middle that can rewrite the query, route to the right source, evaluate whether what came back is actually good enough, and loop again if not.

REVENUE DURABILITY IS FAILING IN THE AGE OF AI

Every VC, PE firm, and public market investor is circling the same question in 2026: Is this company's revenue actually durable? The answer is crushing valuations, freezing M&A, and making fundraising brutal. Bill.com dropped from 90% growth to 12%. Snowflake fell from 73% to 26%. The uncomfortable truth is that nobody has real confidence that software revenue will hold up over the next decade, and that uncertainty alone is enough to reshape how every founder thinks about pricing, retention, and defensibility.

ORBITAL DATA CENTERS, PART 1: THERE'S NO WAY THIS IS ECONOMICALLY VIABLE, RIGHT?

Replicating the output of a single large terrestrial data center would require hundreds of satellites. Building things in space is enormously expensive. While there are advantages to putting data centers in space, such as the abundant energy provided by the Sun, the high costs make such a venture likely unviable. There may also be other impacts of putting data centers into space, such as crowding out the night sky, which would impact astronomers and other space-based ventures.

AUTO MODE FOR CLAUDE CODE

Auto mode for Claude Code is an alternative to --dangerously-skip-permissions. It allows Claude to make permission decisions autonomously. A separate classifier model reviews conversations before each action runs to see whether actions match intent. It blocks actions that escalate beyond the task scope or seem otherwise unsafe. Auto mode ships with an extensive set of default filters, and users can customize them further with their own rules.
