We use Crystal a lot too at Crunchy Bridge. It is used for all of the on-instance programs, the per-region monitoring service, as well as the customer CLI. I'm a big fan of Crystal, and wrote the postgres driver for the language :)

However a main reason we used Ruby was for the production REPL which lets us manage our entire server fleet with like 1/3 of the staff we'd need otherwise.

For the control plane part of Crunchy Bridge, on day one I decided to go with the deleted_records table that is mentioned at the end of this post. It's been great. No need to keep around dead data that no one ever looks at.

We don't need to have `where deleted_at is null` on every single query. But the best part though is our actual working data set of records we actually care about is tiny compared to the deleted cruft that would have otherwise been just sticking around forever. Backups and restores take no time at all. It's really cool that postgres lets you have conditional indexes on things, but it's even cooler not to need them.

Overall sorbet has been good and useful, so thank you. But you just have to be careful when you're not using the same version of ruby that stripe uses. I recently got hit by a bug:

    # typed: strict
    extend T::Sig

    sig {params(x: Integer, y: String).void}
    def run(x:, y:)
      puts(x + 1, y)
    end

    args = {
      x: 1,
      y: "Hi"
    }

    run args

type checks just fine in sorbet, but is an error in ruby 3+. It works though (with errors) in 2.7 and lower which is what Stripe uses from what I gather.

If there is something like heartbleed that needs to update a common dependency, how does NixOS deal with that? Do you need to rebuild everything that uses that dependency, instead of just changing the shared library on a more traditional os?

> Over the past couple of weeks, Stripe began handling a large, though undisclosed, portion of Amazon’s transactions. Neither company will address the scope of the deal—which was only revealed by Stripe’s addition of Amazon’s logo to its website—but it could help Stripe greatly increase its transaction volume.

So, reading into this, amazon presumably invested in stripe, then gave it some transaction traffic to juice the numbers to make an S-1 look better?
