How to compare Unicode characters that “look alike”?
...tion to the former, so you can normalize the string to FormKC or FormKD to convert the micro signs to mus.
However, there are lots of sets of characters that look alike but aren't equivalent under any Unicode normalization form. For example, A (Latin), Α (Greek), and А (Cyrillic). The Unicode w...

Analyze audio using Fast Fourier Transform
...Ed.. It was very helpful for me.
So that is what those numbers represent. Converting to a percentage of height could be done by scaling each frequency component magnitude by the sum of all component magnitudes. Although, that would only give you a representation of the relative frequency distributi...
Is it possible to set a number to NaN or infinity?
...
The numpy functions also work for numpy arrays and everything that can be converted to one (like lists, tuple, etc.)
There are also functions that explicitly check for positive and negative infinity in NumPy: numpy.isposinf and numpy.isneginf.
Pandas offers two additional functions to check for NaN...
What does the Q_OBJECT macro do? Why do all Qt objects need this macro?

How do I save a stream to a file in C#?
...r-complicate things with StreamReader if you already have a stream you can convert to bytes directly with .ToArray()!
Only potential downsides I can see in doing it this way is if there's a large file you have, having it as a stream and using .CopyTo() or equivalent allows FileStream to stream it...
How do I use reflection to call a generic method?
...f you know the return type of the function call then you should implicitly convert it to the required type so the rest of the code is statically typed:
string result = ProcessItem((dynamic)testObjects[i], "test" + i, i);
You'll get a runtime error if the type doesn't match.
Actually, if you try ...
