Welcome to Lobste.rs! New York Times articles are generally not well recieved or removed by moderators, because either they are offtopic, or in this case, are targeted at a non-technical audience (explaining prime numbers, simplification of encryption to RSA). See https://lobste.rs/domain/nytimes.com.
In the future, I’d look for something more detailed and aimed at a more technical audience.
What you did here is fantastic and I’m going to try to start doing this, too.
Thanks for the tip!
