Why do people say there is modulo bias when using a random number generator?
...te the numbers between 0 and 2 with equal probability. Of course for small ranges this might not be the biggest issue but for a larger range this could skew the distribution, biasing the smaller numbers.
So when does rand()%n return a range of numbers from 0 to n-1 with equal probability? When RAN...
How many double numbers are there between 0.0 and 1.0?
...tween powers of two, because there are many powers of two included in that range, and, also, one gets into the thorny issues of denormalized numbers. 10 of the 11 bits of the exponents cover the range in question, so, including denormalized numbers (and I think a few kinds of NaN) you'd have 1024 t...
Streaming a video file to an html5 video player with Node.js so that the video controls continue to
...
The Accept Ranges header (the bit in writeHead()) is required for the HTML5 video controls to work.
I think instead of just blindly send the full file, you should first check the Accept Ranges header in the REQUEST, then read in and s...
What does the C++ standard state the size of int, long type to be?
... not specify the size of integral types in bytes, but it specifies minimum ranges they must be able to hold. You can infer minimum size in bits from the required range. You can infer minimum size in bytes from that and the value of the CHAR_BIT macro that defines the number of bits in a byte. In all...
Last non-empty cell in a column
...on can not find an exact match, it chooses the largest value in the lookup_range (in our case {1,1,..,#DIV/0!,..}) that is less than or equal to the value (in our case 2), formula finds last 1 in array and returns corresponding value from result_range (third parameter - A:A).
Also little note - a...
Create array of all integers between two numbers, inclusive, in Javascript/jQuery [duplicate]
...
In JavaScript ES6:
function range(start, end) {
return Array(end - start + 1).fill().map((_, idx) => start + idx)
}
var result = range(9, 18); // [9, 10, 11, 12, 13, 14, 15, 16, 17, 18]
console.log(result);
For completeness, here it is w...
