How to force ASP.NET Web API to always return JSON?
...onfiguration.Formatters.JsonFormatter);

this code is pain for unit testing but that's also possible like this:
sut = new WhateverController() { Configuration = new HttpConfiguration() };
sut.Configuration.Formatters.Add(new Mock<JsonMediaTypeFormatter>().Object);

Manually raising (throwing) an exception in Python
...t For me the role of assertions isn't error-checking per se (which is what testing is for), but they set up fences within the code that certain bugs can't get through. So it becomes easier to track down and isolate the bugs, which will inevitably occur. This is just good habits that take little effo...
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 timeit import Timer
Nelements = 10000

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...

is_file or file_exists in PHP

is_file() is the fastest, but recent benchmark shows that file_exists() is slightly faster for me. So I guess it depends on the server.
My test benchmark:

Why return NotImplemented instead of raising NotImplementedError
