> Dachshunds are extremely intelligent dogs who are brave and tough in the face of danger. They had to be, in order to win a battle with a fierce badger.

You need a several Dachshunds to take out a badger. Some will probably die during the hunt. Badgers are larger and have much bigger teeth and huge claws. What is that tiny dog's face going to be able to do?

They also used to arrange fights to bet on called Badger Baiting...

What's the point? Any progress will require massive amounts of funding to solve these issues and states can't print money.

Oh, I was only running the C program not the Go binary which orchestrates it, that's why I wasn't seeing the longer stats. But I'm still getting no duplicate collisions.

I'm running it on real hardware (Ryzen 9 5900X, 12 cores 24 threads) and all I'm doing is executing the program once. My understanding is that the program is using runtime.GOMAXPROCS(0) to ensure it's using all available CPU cores because that falls back to runtime.NumCPU ?

Comment out CLOCK_MONOTONIC_RAW because that's not available on FreeBSD, and it looks OK to me? My understanding is that we should see some timestamps repeating if there's a collision, correct? I can't get any collisions...

Miami-Dade and Broward requires buildings to be built to modern hurricane standards ("best in the world") but the rest of the state has resisted adopting the same standards.

Namecheap's API is like this. It's baffling. People wipe out their entire zones by accident
