It doesn't seem that implausible for a program to be reading through a dataset and issue a notice for a measurement above some value. If the dataset encoded years in just two digits, it (almost) makes sense that the program would report it 100 years off.

Imagine:

    with open(file) as f:
        for record in f:
            year, month, day, time, magnitude = record.split()
            
            if magnitude > 5:
                raise_alarm()

In case I just missed them, are there some comparable projects to this? Is there an established library in the space?

Steve, thanks for all your work on this and with Rust. Your attitude toward teaching and your writing ability go a long way in encouraging people to learn and in having the lesson be worthwhile.

Edit: The original submission (see dang's post) references a similar set of maps[0] for the Mississippi River, which are equally beautiful and even more impressive.

* Why is constant time desirable here, if the operation can be quicker for some inputs?
