@chesterzelaya when i was back at fitbit, we engineered a very elaborate mtls system that prevented chinese knockoffs from using our backend. we literally were burning certificates in authentic devices on the assembly line.

not enough people doing things for the love of the game anymore

too much money, status, politics involved

ultimately you should just do things cause you like doing things

It is 70 and sunny in New York City, we’re heading to a kite festival, and I haven’t heard the words “agent” or “token” once all morning.

Greatest city in the world.

@SusieM414141 we had these at a minor league ballpark 10 years ago. it’s a magnet at the bottom. expensive cup that gets translated into more expensive beer for the consumer. company that created it made a fortune with deals like this. also lots of wasted beer!

@ParvSondhi welcome to nyc! i miss SF every day but love hanging out with friends and meeting strangers in all walks of life that dont talk about work :)

@nkohari jj doesn’t quite do what you’re describing, but it does a better job of “telling a story” since you’re in control of how the changes look for reviews (eg no fix: fix: pollution). jj evolog does a good job of describing how the changes developed for reviewers. we use it at work.

[kacy ☕️ @kacyf]

@nkohari heh, i’ve toyed around with this idea a bunch over the years. https://t.co/zyovpmYMbr is the closest and probably best in this category imo.

i built out a device attestation library to complement the apple and android sdks a few months back with this but shelved it (again)

I’m increasingly convinced you can tell everything you need to know about a person by observing how they treat service workers.

@zackkanter if you’re interested in what k8s would look like if it were built on 2026, I’m building https://t.co/mgBxdceW80. still early, but it’s far simpler and goes straight to the kernel.
