What does the exclamation mark mean in a Haskell declaration?
...ause you can't look inside it without it existing). The first, since we're testing it, we need to evaluate all the way to 4, where we realize it doesn't match.
The second doesn't need to be evaluated, because we're not testing it. Thus, rather than 6 being stored in that memory location, we'll just...

Way to get number of digits in an int?
...
See my benchmark unit test below(wich may be flawed too i am no benchmark expert). Over a large number of runs (100 000 000), the speed is 11s to 8s on my machine hardly twice as fast.

Parsing command-line arguments in C?
...uild it (gcc-7.3) and found that the library builds and works, but the C++ test could do with some minor work. iostream.h should become iostream, and using namespace std; should be added. I will mention it to James. This only affects the C++ API test, not the code itself.

What are the advantages of NumPy over regular Python lists?
..., histograms, etc. And really, who can live without FFTs?
Speed: Here's a test on doing a sum over a list and a NumPy array, showing that the sum on the NumPy array is 10x faster (in this test -- mileage may vary).
from numpy import arange
from timeit import Timer
Nelements = 10000
Ntimeits = 100...
Elegant ways to support equivalence (“equality”) in Python classes
...t copies sitting around, then it's usually good add an initial an identity test if other is self. This avoids the more lengthy dictionary comparison, and can be a huge savings when objects are used as dictionary keys.

Create a pointer to two-dimensional array
...dimensional arrays to functions by reference:
int l_matrix[10][20];
void test(int matrix_ptr[static 10][20]) {
}
int main(void) {
test(l_matrix);
}
Unlike a plain pointer, this hints about array size, theoretically allowing compiler to warn about passing too-small array and spot obvious out...
