Difference between ref and out parameters in .NET [duplicate]
...ore use. Ref parameters are passed both into and out of a method.
So, out means out, while ref is for in and out.
These correspond closely to the [out] and [in,out] parameters of COM interfaces, the advantages of out parameters being that callers need not pass a pre-allocated object in cases wher...
Which is faster : if (bool) or if(int)?
...so it compiles to essentially the same code, except for cmpl vs cmpb.
This means that the difference, if there is any, doesn't matter. Judging by unoptimized code is not fair.
Edit to clarify my point. Unoptimized code is for simple debugging, not for speed. Comparing the speed of unoptimized cod...

String.equals versus == [duplicate]
... must be equivalent. The final return true after the while loop does not mean we have the same "Jorman", it means the that the two entities share the same value (equivalent) which does not imply equality. (The Java .equals method is misnamed in this regard).

What is the difference between LL and LR parsing?
... the target string. An LR parse is a left-to-right, rightmost derivation, meaning that we scan from the left to right and attempt to construct a rightmost derivation. The parser continuously picks a substring of the input and attempts to reverse it back to a nonterminal.
During an LL parse, the p...
Can I set max_retries for requests.request?
...esponse with a response code in the 3xx range.
raise_on_status – Similar meaning to raise_on_redirect: whether we should raise an exception, or return a response, if status falls in status_forcelist range and retries have been exhausted.
NB: raise_on_status is relatively new, and has not made it...

animating addClass/removeClass with jQuery
...ince you are not worried about IE, why not just use css transitions to provide the animation and jQuery to change the classes. Live example: http://jsfiddle.net/tw16/JfK6N/

What's the point of const pointers?
...le-time, rather than run-time, by getting the compiler to enforce what you mean.
Even though it doesn't change the functionality, adding const generates a compiler error when you're doing things you didn't mean to do. Imagine the following typo:
void foo(int* ptr)
{
ptr = 0;// oops, I meant *...
