Two of the day's bigger infrastructure bets landed within hours of each other: a runtime absorbed into the agent stack, and a hardware maker raised on the compute shortage. Cloudflare is acquiring Deno outright, and the Deno runtime will end development in a year. Both companies announced the deal today: Cloudflare gets the team and celld — Deno's open-source implementation of the Durable Objects pattern — with the goal of making self-hosted workerd a first-class way to run the Workers…
