I've been thinking maybe this has nothing to do with pi the number and more to do with pie the dish.
So probably I'm wrong, but when googled for source/origin of pie I got result as Romans/Greeks/Greece? If the answer is Greeks the answer also coincides with the origin/root of the letter pi as a Greek letter and the country is also named Greece (6).
Having different meanings for the same word in different industries is one thing...
I've heard IT terms used differently in different IT companies.
Like there was this company where they used the term "front-end" for everything from code running in the browser to the IIS service that served the pages.
The back-end, for them, was everything that did not serve HTML pages.
To me, and other places I've worked, the front-end is just what's running in your browser, everything else is back-end.
Some people also use the term back-end to mean their database, while others don't include it and mention a database explicitly.
And those are just two words.
It's all just very confusing...
I thought it might be interesting to write a bit about System.Numerics.Vector (and probably System.Runtime.Intrinsics), which is one of those things that can be helpful (I still don't exactly like the Vector<T> API, but it can be used for some things and for other things I can throw in some System.Runtime.Intrinsics), but used more rarely than it deserves. It's not easy to get into.
Of course I can cover the usual suspects such as linear algebra and Fourier transforms, but it would be more interesting to have some examples that are less on the "pure math" side and more on the "just random stuff that comes up in programs" side.
Good candidates look like a loop over one or more arrays, nested loops and some "mild conditionals" and "innocent function calls" (Math.Max and such) are fine, but if it's a big rat's nest of control flow I probably can't use it.
