This is not a novel, original or unusual insight: it's what lots of people (myself and others) have been saying for years, and is also in the most recent of the much-maligned IMF reports on China. But it runs directly contrary to the official government diagnosis which is that aggregate demand is fine and the economy mainly su…

I just realized something I'm very confused by: Is it really the case “pinning’ in NixOS prototypically means “pinning a single version of the entire package repository, and then pulling in whatever versions it contains”? I mean, "it's all just code" and it seems to be *possible* to mix and match via `fetchTarball`. But is pinning the universe as-a-unit really the normal pattern?
