These can be helpful.
If you're finding by Contains then it'll be like this
$("input[id*='DiscountType']").each(function (i, el) {
//It'll be an array of elements
});
If you're finding by Starts With then it'll be like this

What is the advantage of using REST instead of non-REST HTTP?
... POST for all the setters, we try to have the URLs identify resources, and then use the HTTP actions GET, POST, PUT and DELETE to do stuff to them. So instead of
GET /get_article?id=1
POST /delete_article id=1
You would do
GET /articles/1/
DELETE /articles/1/
And then POST and PUT correspond...
Select random row from a sqlite table
...aster than anktastic's (the count(*) costs a lot, but if you can cache it, then the difference shouldn't be that big), which itself is much faster than the "order by random()" when you have a large number of rows, although they have a few inconvenients.
If your rowids are rather packed (ie. few del...
Public Fields versus Automatic Properties
...ts value into the local variable), pass the local variable as ref/out, and then set the property to the value the local variable then has. But then the method called does not itself access the property, it accesses the local variable you made there.

“Unable to find remote helper for 'https'” during git clone
...when you compile git can cause this.
If you install (lib)curl-devel, and then rebuild/install git, this should solve the problem:
$ yum install curl-devel
$ # cd to wherever the source for git is
$ cd /usr/local/src/git-1.7.9
$ ./configure
$ make
$ make install

...rstanding the problem
Browsers make HTTP requests to servers. The server then makes an HTTP response.
Both requests and responses consist of a bunch of headers and a (sometimes optional) body with some content in it.
If there is a body, then one of the headers is the Content-Type which describes...
Computational complexity of Fibonacci Sequence
...intuitively figure out that this function is asymptotically O(2n). You can then prove your conjecture by induction.
Base: n = 1 is obvious
Assume T(n-1) = O(2n-1), therefore
T(n) = T(n-1) + T(n-2) + O(1) which is equal to
T(n) = O(2n-1) + O(2n-2) + O(1) = O(2n)
However, as noted in a comment, ...
