What is self-documenting code and can it replace well documented code? [closed]
...is being done:
/* compute displacement with Newton's equation x = vₒt + ½at² */

float timeInSeconds = 5;
float displacement = (1 / 2) * gravitationalForce * (timeInSeconds ^ 2);
And the final version of code as documentation with zero comments needed:

Difference between Big-O and Little-O Notation
...
x² ∈ O(200 * x²)
The following are true for little-o:
x² ∈ o(x³)
x² ∈ o(x!)
ln(x) ∈ o(x)
Note that if f ∈ o(g), this implies f ∈ O(g). e.g. x² ∈ o(x³) so it is also true that x² ∈ O(x³), (again, think of O as <= and o as <)

What is a plain English explanation of “Big O” notation?

N² → (2N)² = 4(N²)
... I double-cubed (octuple) the time an O(N³) ("cubic time") algorithm takes." (e.g. a problem 100x as big takes 100³=1000000x as long... very unsustainable)

Ignoring accented letters in string comparison
...re details on MichKap's blog (RIP...).
The principle is that is it turns 'é' into 2 successive chars 'e', acute.
It then iterates through the chars and skips the diacritics.
"héllo" becomes "he<acute>llo", which in turn becomes "hello".
Debug.Assert("hello"==RemoveDiacritics("héllo"));
