When should I use Arrow functions in ECMAScript 6?
...render = function () {
var book = this;
this.$pages.each(function (index) {
var $page = $(this);
book.draw(book.currentPage + index, $page);
});
};
We must use function in order for each to bind this dynamically. We can't use an arrow function here.

How to retrieve the current value of an oracle sequence without increment it?
...t max(PK) from TheTable is also very fast, probably because a PK is always indexed. Or select count(*) from TheTable. I am still experimenting, but both SELECTs seem fast.
I don't mind a gap in a sequence, but in my case I was thinking of polling a lot, and I would hate the idea of very large gaps....
“for loop” with two variables? [duplicate]
...you would want (since it is impossible for there to be the same element at index 9 when one of the lists is only 5 elements long). If that is what you want, go with this:
def equal_elements(t1, t2):
return [x for x, y in zip(t1, t2) if x == y]
This will return a list containing only the elem...

How do you bind an Enum to a DropDownList control in ASP.NET?
...
By the way in C#, you can't access to Array with index itemNames[i], you only could do it with arrayObject.GetValue(i) and in that way, it's returning just the name in both cases.

There are many more options here: http://docs.python.org/install/index.html, including the option of appending sys.path with the user-level directory of your development code, but in practice I usually just symbolically link my local development dir to site-packages - copying it over has t...
Getting started with Haskell
... to stick.
Now, in learning various imperative/OO languages (like C, Java, PHP), exercises have been a good way for me to go. But since I don't really know what Haskell is capable of and because there are many new concepts to utilize, I haven't known where to start.

How to add an extra column to a NumPy array
...e vector, for instance duplicate the last column:
b = np.insert(a, insert_index, values=a[:,2], axis=1)
Which leads to:
array([[1, 2, 3, 3],
[2, 3, 4, 4]])
For the timing, insert might be slower than JoshAdel's solution:
In [1]: N = 10
In [2]: a = np.random.rand(N,N)
In [3]: %timeit ...
