"Age verification" laws are actually "upload your ID or get your face scanned to access every website, ending anonymity and associating your identity with everything you do online" laws and if more people understood that they would not be down for this authoritarian nonsense

I love that @signal.org is using Microsoft's own DRM copyright API to block Windows from its own stupid new "feature" which takes screenshots of, well, everything and saves them. It's like an intellectual property Jedi mind trick.

WhatsApp Is Gambling That It Can Add AI Features Without Compromising Privacy WhatsApp's AI tools will use a new β€œPrivate Processing” system designed to allow cloud access without letting Meta or anyone else see end-to-end encrypted chats. But experts still see risks.

Be an imperfectionist.

Imperfectionists hit publish.

Imperfectionists ship product.

Imperfectionists iterate publicly.

It's not that they don't believe in excellence.

They dream big, but iterate small.
