In my experience Spotify's song/playlist recommendations are not great, but the album recommendations have a pretty high hit rate. I'm not sure why this would be.
Did they get a lot better recently? For years I rarely even looked at them because they were so banal and repetitive, but about six months ago they suddenly became something to stay on top of.
Aha. I'm also in California. This explains why the ads stand out more to me when watching the (baseball) World Series and listening to podcasts -- because generally, gambling sites don't waste their time and money advertising to me.
You understate your point: the 83% rate is much, much more than 3x worse. To kill 100 intended targets, a 28.6% civilian death rate means you'll need to kill `N / (100 + N) = 0.286` (N = 40.06) civilians. With an 83% civilian death rate, to kill 100 intended targets, you need to kill `N / (100 + N) = 0.83` (N = 488) civilians. It is about 12x worse to have an 83% civilian death rate compared to a 28.6% rate.
Almost all energy released in earthquakes is released in the biggest ones. No realistic number of smaller quakes is ever going to add up to even the single biggest earthquake ever recorded.
Another factor is that literacy rates were very low before colonization, in Vietnam to read or write using Chinese characters was never a broadly known skill (outside of the elite). This is a pretty big contrast to Japan, which had double-digit rates of literacy during the same era.
I've only heard it used in tech when you have actual operations, in my experience that meant lab managers and technicians. I'm not sure what it is supposed to mean in this context.
How could one prove this is aperiodic? I'm guessing maybe you can prove that some or most of the triangles have globally unique rotations regardless of N?
In college we discovered everyone's ID number was evenly divisible by 13. Presumably it's because that's the smallest number you'd need so that you could detect any one digit being incorrect, or two adjacent digits being swapped (I think?). Or that it's just very easy to implement the increment when assigning new numbers.
It's what quite a few banks used to use as a check digit, maybe that where you remember it from. But it depends on the size of the number you want to verify and exactly what system is employed. Lots of banks used 9 or 10 digit numbers which worked with a "11 check". Nine was also often used on smaller numbers.
You can use any prime afaik for this example but your number space will be limited.
I've definitely done it in places (in the US) where locally it was not legal. But it's not like the cops ever checked and caused us trouble about it, so it's easy to get away with it if there aren't other legal issues going on.
