My Understanding of HTTP Polling, Long Polling, HTTP Streaming and WebSockets
...
There are more differences than the ones you have identified.
Duplex/directional:
Uni-directional: HTTP poll, long poll, streaming.
Bi-direcitonal: WebSockets, plugin networking
In order of increasing latency (approximate):

Is MATLAB OOP slow or am I doing something wrong?
...per se - MATLAB has a JIT - but MATLAB's looser typing and syntax may mean more work at run time. (E.g. you can't tell from syntax alone whether "f(x)" is a function call or an index into an array; it depends on the state of the workspace at run time.) It may be because MATLAB's class definitions ar...
NOT using repository pattern, use the ORM as is (EF)
...uld perfect the use of it and my implementation of “Unit Of Work”. The more I started digging I started asking myself the question: "Do I really need it?"

What does T&& (double ampersand) mean in C++11?
...:forward function that can properly forward lvalue/rvalue references. For more information about how std::forward works, see this excellent answer.
This enables us to define the factory function like this:
template <typename T, typename A1>
std::unique_ptr<T> factory(A1&& a1)

How do we control web page caching, across all browsers?
...ags to avoid confusion by starters and rely on hard HTTP response headers. Moreover, specifically those <meta http-equiv> tags are invalid in HTML5. Only the http-equiv values listed in HTML5 specification are allowed.
Verifying the actual HTTP response headers
To verify the one and other, y...
How to choose an AES encryption mode (CBC ECB CTR OCB CFB)?
...
ECB should not be used if encrypting more than one block of data with the same key.
CBC, OFB and CFB are similar, however OFB/CFB is better because you only need encryption and not decryption, which can save code space.
CTR is used if you want good parallelizati...
What is the difference between quiet NaN and signaling NaN?
...
In contrast, NaNs are for more normal programming. They can be produced by normal operations when there is no numerical result (e.g., taking the square root of a negative number when the result must be real). Their purpose is generally to allow arithm...
