Reducing Python String Memory Use in Apache Arrow 0.12
You're right, PyUnicode_InternInPlace (which is called by sys.intern) already caches results using a regular Python dictionary, so @functools.cache wouldn't add any value.
It happened a long time ago, but I think I misread something about sys.intern not being able to handle lots and lots of strings, so I added an extra layer of caching, but it looks like it's not needed anymore.

Scientific Computing with Perl
See also my blog post "How you average numbers matters"[2].
> Now, in the real world, you have programs that ingest untold amounts of data. They sum numbers, divide them, multiply them, do unspeakable things to them in the name of “big data”. Very few of the people who consider themselves C++ wizards, or F# philosophers, or C# ninjas actually know that one needs to pay attention to how you torture the data. Otherwise, by the time you add, divide, multiply, subtract, and raise to the nth power you might be reporting mush and not data.
> One saving grace of the real world is the fact that a given variable is unlikely to contain values with such an extreme range. On the other hand, in the real world, one hardly ever works with just a single variable, and one can hardly every verify the results of individual summations independently.
Correct algorithms may be slower, but I am hoping that it is easy understand why they ought to be preferred.

Windows, Ruby and Long Paths
I started going through the Python codebase, but all I could find was the addition of the longPathAware manifest key, which kind of dismantled all my preconceptions about how application manifests work. Maybe having the manifest was indeed enough.
