How to return a result from a VBA function
...ct type, then you must use the Set keyword like this:
Public Function testRange() As Range
Set testRange = Range("A1")
End Function
Example usage:
Dim r As Range
Set r = testRange()
Note that assigning a return value to the function name does not terminate the execution of your function. I...
How to get the nth element of a python list or a default if not available
...an empty list if n => len(a)
Here is an example of how this works with range(5)
>>> range(5)[3:4]
[3]
>>> range(5)[4:5]
[4]
>>> range(5)[5:6]
[]
>>> range(5)[6:7]
[]
And the full expression
>>> (range(5)[3:4]+[999])[0]
3
>>> (range(5)[4:5...
Why do we have to normalize the input for an artificial neural network?
...
Some inputs to NN might not have a 'naturally defined' range of values. For example, the average value might be slowly, but continuously increasing over time (for example a number of records in the database).
In such case feeding this raw value into your network will not work v...
How to initialize a vector in C++ [duplicate]
...t page, actually. The constructor can take the first and last element in a range and create a vector with everything in between. The tipoff is the & will result in memory addresses.

Which regular expression operator means 'Don't' match this character?
...
There's two ways to say "don't match": character ranges, and zero-width negative lookahead/lookbehind.
The former: don't match a, b, c or 0: [^a-c0]
The latter: match any three-letter string except foo and bar:
(?!foo|bar).{3}
or
.{3}(?<!foo|bar)
Also, a correction...
How important is the order of columns in indexes?
... but keep in mind an index is stored on several pages and is a tree with a range of values, while Column 1 above does negate 1/2 the possibilities, the index already knows which index page to go straight to for the Column2 value, it does not necessary need Column 1 to narrow down the set.

generate days from date range
... starting from the current date. If you want to generate any kind of dates range (past, future, and in between), you will have to use this view instead:
CREATE VIEW dates AS
SELECT
SUBDATE(CURRENT_DATE(), number) AS date
FROM
numbers
UNION ALL
SELECT
ADDDATE(CURRENT_DATE(), numb...
Java equivalent of unsigned long long?
...g(objScannerInstance.next("\\d+")); Not exactly elegant because it lacks a range check, but it would let you pull in long numeric inputs that would otherwise possible exceed the range of a signed long. (Leverages the fact that Scanner::next(...) can also accept either a Pattern object or String patt...
Python division
I was trying to normalize a set of numbers from -100 to 0 to a range of 10-100 and was having problems only to notice that even with no variables at all, this does not evaluate the way I would expect it to:

Mapping two integers to one, in a unique and deterministic way
..., here. The limitation of Cantor pairing function (relatively) is that the range of encoded results doesn't always stay within the limits of a 2N bit integer if the inputs are two N bit integers. That is, if my inputs are two 16 bit integers ranging from 0 to 2^16 -1, then there are 2^16 * (2^16 -1)...
