This is an unexpected programming application. It's nice that the farmer actually changed behavior after receiving the phone call. At first, I thought there was a clear improvement. This problem essentially boils down to finding the intersection point of three circles. But it's also likely that with the small fuzz from imprecise time measurement that the three measured circles wouldn't actually intersect. I would gue…

Oregon state and Corvallis have a noise ordinances. The farm likely would have faced significant fines if he hadn’t solved the problem.

I'm curious if regularly firing these cannons on a schedule actually works to scare the geese away. When reading about the accident of Ural Airlines Flight 178 [1], the airport had air cannons for scaring off birds, but they fired them on a regular schedule instead of in response to particular flocks, and the local birds just got used to it. I don't know if the circumstances are similar enough for that to apply with these farms and birds, though.

Sometimes you have to fire a few rounds at them.[1]

Not sure why you are being downvoted, this is the best kind of pedanticism.

A large number of people believe it impolite to correct someone's language. I've seen it even called "colonial" to correct written grammar, that we should just let language evolve naturally and not try to enforce rules on others. I am not of that mindset.

You should read Power of Babel if you like this topic!

I really dislike Python. This is a clean install of Python straight from the Python developers in a clean container. And it doesn't work. I figured I must need "points" so I pip-installed that. Feels like every time I try to use Python, stupid, incomprehensible errors such as this occur: ``` root@1623eb794014:/# ./tri.py Traceback (most recent call last): File "//./tri.py", line 6, in from points import Point, Block…

In this case it’s the fault of the author in either not including all the source code, or having undocumented dependencies

The author explicit mentions it twice.

I am letting language evolve naturally, by providing evolutionary pressure. The people who tell me not to correct people are the ones who don't let language evolve.

This is the point at which I would have changed my attitude to the situation quite dramatically. Given the opportunity to own up and simply apologize and fix the issue, the fellow just went full lie-to-your-face mode. What in the everloving heck is wrong with people?
