IF SOMEONE SELLS YOU STOCK AT YOUR BID PRICE, LOWER YOUR BID AND OFFER SLIGHTLY: IF SOMEONE IMMEDIATELY “HITS YOUR BID,” THEN YOU MIGHT WORRY THAT YOUR BID WAS ACTUALLY TOO HIGH AND YOU COULD’VE PAID LESS.

When you launch a Developer ID signed app, it may perform an OCSP check. You can see this if you take a packet trace. The check consists of an HTTP GET request (port 80, unencrypted!) to ocsp.apple.com with a path that is both Base64 encoded and URL encoded. According to the OCSP format, the encoded bytes end with the serial number of the Developer ID cert. The OCSP check is performed by the trustd processes (/usr/libexec/trustd). An OCSP check is different and separate from a notarization check, which is performed by the syspolicyd process. Developer ID certs were always checked for revocation via OCSP, before notarization even existed.

The title of this essay inverts the title of a book about economics by Donald Mackenzie, An Engine Not a Camera. The premise of that book is that economics theories are engines that produce (via policies and institutions) economic behaviors, but trick us into thinking they merely describe them. Modern AI has the reverse problem. It’s a camera that tricks us into thinking it’s an engine that “generates” rather than “sees” things. As an aside, this weird symmetry makes me suspect that economics and modern AI are true duals of some sort — maybe the way to get to AI with agency is to bolt on an economics theory.
